Description

一种第一连接件、连接组件及连接系统 技术领域
本发明涉及一种第一连接件，用于二合一、三合一或四合一家具五金连接件；本发明还涉及一种连接组件及连接系统，用于连接第一构件和第二构件，特别用于连接家具构件。
背景技术
目前，随着人们的审美观念不断提高，两个家具板件之间逐渐采用隐形性连接件实现隐形式连接，从而提高家具或设备的美观性，其中，二合一连接件或三合一连接件或四合一连接件等隐形连接件广泛应用于两个家具板件之间的连接。如图1-图3所示，现有的三合一连接件主要由预埋螺母10、连接杆20及偏心轮30组成，使用时，预埋螺母10预埋在第一构件6’的第一安装孔61’内，偏心轮30安装在第二构件7’的第二安装孔71’内，连接杆20的第一端通过预埋螺母10与第一构件6’牢固连接，预埋螺母10起到加固作用，连接杆20的第二端插入第二构件7’的内部并与偏心轮30牢固连接，从而使第一构件6’与第二构件7’通过三合一连接件实现隐形式连接，同时三合一连接件的可拆卸性强，可以通过多次拆装来实现第一构件6’与第二构件7’的拆装。
其中，上述连接杆20一般为金属材质或金属配塑料材质，连接杆20的第二端端部设有用于连接偏心轮30的圆头201。现有技术中，为了使连接杆20的第一端能够在预埋螺母10中转动以实现牢固连接，连接杆20的圆头201上开设有一字槽或十字槽或六边形槽，采用螺丝刀或六角扳手转动连接杆20的圆头201以使连接杆20的第一端在预埋螺母10中转动。其中，根据现有的一般使用习惯，为了达到较好的效果，连接杆20的圆头201的直径尺寸设计较大且高度尺寸较大，以 确保连接杆20的圆头201能够多次操作，但这导致现有锌合金材质的偏心轮30的直径尺寸需要大于12mm(通常为15mm)，从而导致第二构件7’的第二安装孔71’的孔径较大，用户容易通过较大孔径的第二安装孔71’观察到偏心轮30，从而导致三合一连接件的隐形性较低，影响了家具的美观性。相同地，二合一连接件或四合一连接件也存在连接杆20的圆头201的直径尺寸较大的现象，从而导致第二构件7’上的开孔孔径较大，导致二合一连接件或四合一连接件的隐形性较低，影响了家具的美观性。

具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指 示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本发明的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
现有技术中，如图1-图2所示，三合一连接件由预埋螺母10、连接杆20及偏心轮30组成，主要用于实现两个家具板件之间的隐形性连接。其中，设定其中一个家具板件为第一构件6’，另一个家具板件为第二构件7’，第一构件6’与第二构件7’的形状或材质可以相同，也可以不相同，形状例如呈板状体或块状体或柱状体等，材质可以为木质、塑料、金属、或者高分子合成材料等或其组合件，此处不作限定。
在使用三合一连接件时，第一构件6’开设有第一安装孔61’，第二构件7’开设有第二安装孔71’，将预埋螺母10预埋在第一构件6’的第一安装孔61’内，偏心轮30安装在第二构件7’的第二安装孔71’ 内，连接杆20的第一端通过预埋螺母10与第一构件6’牢固连接，预埋螺母10起到加固作用，连接杆20的第二端插入第二构件7’的内部并与偏心轮30牢固连接，从而使第一构件6’与第二构件7’通过三合一连接件实现隐形式连接。此外，现有技术中，还存在二合一连接件或四合一连接件，其中二合一连接由连接杆20及偏心轮30组成，使用时连接杆20的第一端直接安装在第一构件6’的第一安装孔61’内，连接杆20的第二端插入第二构件7’的内部并与偏心轮30牢固连接，因此二合一连接件相比于三合一连接件省略使用预埋螺母10，导致连接牢固性较为一般。四合一连接件的连接方式请参考本领域中的现有技术，此处省略说明。
无论是三合一连接件或二合一连接件，现有的连接杆20的第二端端部均设有用于连接偏心轮30的圆头201，同时圆头201上开设有一字槽或十字槽或六边形槽(通常是十字槽)，采用螺丝刀作用于十字槽以驱动圆头201转动，从而使连接杆20的第一端锁紧于预埋螺母10内或第一构件6’的第一安装孔61’内。由于连接杆20的长度尺寸较大，为了确保连接杆20的第一端在预埋螺母10的内部或第一构件6’的第一安装孔61’的内部顺利转动，本领域中通常需要将连接杆20的直径尺寸设计较大，以确保圆头201的十字槽够大够深，用于确保螺丝刀作用在圆头201的作用力以稳定驱动连接杆20转动。此外，较大直径的圆头201才能确保螺丝刀重复操作，以实现连接杆20在第一构件6’上的多次拆装。
基于上述圆头201的直径尺寸较大，导致与圆头201配合连接的锌合金材质偏心轮30的直径尺寸需要大于12mm，从而导致第二构件7’上的第二安装孔71’的孔径较大，较大孔径的第二安装孔71’破坏了第二构件7’的美观性，同时当第一构件6’与第二构件7’完成连接后，用户容易通过第二安装孔71’观察到偏心轮30，导致现有的三合一连接件或二合一连接件的隐形性较低，降低了家具的美观性。
此外，第一构件6’与第二构件7’采用四合一连接件也存在第二 安装孔71’的孔径较大的技术问题，破坏了第二构件7’的美观性，降低了家具的美观性。
实施例1
为此，针对两个家具板件采用现有技术中的二合一连接件或三合一连接件进行连接后存在隐形性较低的技术问题，本发明实施例1公开了一种连接组件，如图19-图22所示，连接组件包括第一连接件1及第二连接件2，使用时先将第一连接件1牢固连接在第一构件6上，第二连接件2安装于第二构件7的第二安装孔71内，通过第一连接件1的一端插入第二构件7的内部并与第二连接件2牢固连接，从而使第一构件6与第二构件7通过第一连接件1与第二连接件2实现隐形式连接。其中，本发明实施例1的第二连接件2的结构与现有技术中的偏心轮30的结构相似，但不同之处在于：第二连接件2的直径尺寸远小于现有技术的偏心轮30的直径尺寸，使得第二安装孔71的孔径较小，提高第二构件7的美观性，同时用户难以通过孔径较小的第二安装孔71观察到第二连接件2，进一步提高家具的美观性。
下面针对本实施例1的第一连接件1的具体结构做进一步说明。
如图3-图18所示，本发明实施例1的第一连接件1包括第一连接件本体，第一连接件本体的一端凸出形成有连接凸台11，第一连接件本体的另一端设有安装部12，安装部12用于锁紧在第一构件6的第一安装孔61内，第一连接件本体在连接凸台11与安装部12之间固定设有操作部13，操作部13与连接凸台11相对间隔设置以形成有连接凹槽14，操作部13用于被外部工具驱动以带动第一连接件本体的至少一部分转动；其中，操作部13的外侧壁上具有至少一个操作平面或操作孔或操作凸点或操作凹槽，或，操作部13的横截面适配于套筒的横截面。
可以理解的是，操作部13相对第一连接件主体是不可转动，以使在外部工具驱动操作部13转动过程中，操作部13带动第一连接件本体的至少一部分转动。其中，操作部13可以一体成型于第一连接件本 体上，例如操作部13与第一连接件本体为金属一体件或塑料一体件；或者，操作部13通过过盈配合的方式套紧于或包覆于或粘接于第一连接件本体的连接凸台11和安装部12之间，以使操作部13固定设于第一连接件本体上，例如操作部13为塑料件，第一连接件本体为金属件。操作部13的横截面需要设计成非圆形或者操作部13需要设计成非圆柱体结构。例如图3-图5所示，操作部13的侧壁上具有至少一个操作平面，操作平面的数量可以为一个或两个或四个或六个等，采用老虎钳或其他钳子或扳手等外部工具夹紧操作部13以驱动操作部13转动。又例如操作部13的侧壁上具有操作孔，采用螺丝刀或金属杆或内六角扳手等外部工具插入操作孔内以驱动操作部13转动。又例如图6所示，操作部13的侧壁上具有操作凸点或操作凹槽，采用老虎钳或扳手等外部工具夹紧操作凸点或操作凹槽以驱动操作部13转动。再例如图3、图4、图7-图20所示，操作部13的横截面适配于套筒的横截面，此时驱动操作部13转动的外部工具为套筒扳手，其中套筒扳手为本领域中常用工具，例如为国标GB T 3390.1-2004的手动套筒扳手，或者其他国标的手动套筒扳手或电动扳手，套筒的横截面为非圆形，包括但不限于三角形或方形或六边形或八边形等多边形状、或椭圆形或腰圆形或花瓣形等，以使套筒扳手驱动套筒在转动的过程中，能够带动操作部13与套筒同步转动，从而使第一连接件1的安装部12的至少一部分转动并与第一构件6牢固连接。
基于上述方案，在第一连接件本体上设有操作部13，操作者采用外部工具作用于操作部13以驱动安装部12与第一构件6连接，操作过程中施力面积大且施力稳定，有效提高第一连接件1在第一构件6上的安装效率及拆装稳定性。同时，如此在第一连接件本体设有操作部13能够缩小第二连接件2的直径尺寸，进而使第二构件7的第二安装孔71的孔径更为微小，提高第二构件7的美观性，同时用户难以通过孔径较小的第二安装孔71观察到第二连接件2，提高第二连接件2在第二构件7上的隐形性，从而提高家具的美观性。
进一步地，第一连接件本体通过连接凸台11与本实施例1的第二连接件2进行可拆卸连接，连接凸台11的横截面呈圆形或椭圆形或方形或六边形或不规则形等，本发明实施例1不对连接凸台11的具体形状做限定。通常情况下，连接凸台11的横截面优选为圆形，且连接凹槽14沿第一连接件本体的外侧壁的周向环绕以呈环形凹槽状，操作者在将第一连接件1固定连接于第一构件6后，不需要区分第一连接件1的安装方向以将连接凸台11顺利插入第二连接件2的内部，提高装配便捷性。
进一步地，在本实施例1的一些实施方式中，当连接凸台11的横截面呈圆形时，连接凸台11的直径尺寸为3-5.3mm，例如为3mm、3.5mm、4.0mm、4.2mm、4.5mm、5mm、5.3mm等，如此设计能够确保第二连接件2的直径尺寸小于12mm,以使本发明实施例1的第二连接件2的直径尺寸远小于现有技术中的偏心轮30的直径尺寸，提高第二连接件2在第二构件7上的隐形性，从而提高家具的美观性。
进一步地，其中，当本实施例1的第一连接件的连接凸台11的直径尺寸在4.2mm-5.3mm范围时，本领域技术人员可以在连接凸台11的端面加工有一字槽或十字槽或六边形槽，在采用螺丝刀或扳手插入该一字槽或十字槽或六边形槽以驱动第一连接件主体转动后，该一字槽或十字槽或六边形槽会发生磨损，难以再次使用；或者，当本实施例1的第一连接件的连接凸台11的直径尺寸在4.2mm-5.3mm范围时，通过手动的或电手的一字或十字或六边形螺丝刀头，难以将第一连接件1直接安装到第一构件6上，因此驱动第一连接件主体再次转动仍需要通过转动操作部13，当安装第一连接件1到第一构件6上时需要操作部13，则连接凸台11的端面设有一字槽或十字槽或六边形槽仍处于本发明的保护范围内。当本实施例1的第一连接件的连接凸台11的直径尺寸在3mm-4.2mm范围时，连接凸台11的端面上难以加工有一字槽或十字槽或六边形槽，此时驱动第一连接件主体转动时完全依靠操作部13，此时与第一连接件1配合的第二连接件2的直径尺寸更为微小， 减小第二构件7的第二安装孔71的孔径以提高隐形性。
相应地，第一连接件主体的具有环形凹槽状的连接凹槽14的直径尺寸小于连接凸台11的直径尺寸，即本发明实施例1的第一连接件主体的具有连接凹槽14的直径尺寸的取值范围为1.8-4mm，例如为1.8mm、2.0mm、2.5mm、3.0mm、3.5mm、4mm等。
进一步地，在本实施例1的一些实施方式中，为了使外部工具更为稳定地驱动操作部13转动以带动第一连接件本体转动，操作部13的横截面面积大于连接凸台11的横截面面积，即由操作部13的外轮廓形成的外接圆的直径尺寸大于连接凸台11的直径尺寸。如此使操作部13与外部工具之间具有较大的接触面积，从而提高第一连接件1在第一构件6的装配稳定性。此外，当外部工具为套筒扳手时，如此操作部13的横截面面积大于连接凸台11的横截面面积能够确保套筒穿过连接凸台11后套设于操作部13上，确保套筒扳手顺利驱动操作部13转动。
进一步地，本发明实施例1的安装部12与第一构件6之间的连接方式包括如下两种：第一种为安装部12包括第一转动部121，使用时将第一转动部121直接置于第一构件6的第一安装孔61内，第一转动部121随操作部13同步转动后与第一安装孔61的内壁侧相互咬紧；第二种为安装部12包括第一膨胀体122及第二转动部123，第二转动部123设于第一膨胀体122的内部并相对第一膨胀体122相对转动，使用时第一膨胀体122设于第一构件6的第一安装孔61内，第二转动部123随操作部13同步转动后使第一膨胀体122的外周壁膨胀，以使第一膨胀体122上的第一紧固凸台122a与第一安装孔61的内侧壁相互咬紧。
下面分别对上述安装部12与第一构件6之间的两种连接方式作详细说明。
作为安装部12与第一构件6之间的第一种连接方式，如图3-图11，安装部12包括第一转动部121，当操作部13被外部工具驱动以实 现转动时，第一转动部121在第一构件6的第一安装孔61的内转动一定角度后与第一安装孔61的内侧壁相咬紧。其中，第一转动部121与第一安装孔61的内侧壁之间的咬紧方式包括如下两种，第一种例如图3-图9所示，第一转动部121为圆柱体状或圆锥体状，且第一转动部121的外周侧壁设有外螺纹，第一转动部121的外螺纹的外径尺寸大于第一安装孔61的直径尺寸，以使第一转动部121在第一安装孔61内沿第一转动方向(通常为顺时针方向)转动时，第一转动部121自攻式旋入第一安装孔61内以使第一转动部121的外螺纹与第一安装孔61的内侧壁相互咬紧，以使第一连接件1固定连接于第一构件6上。
作为第一转动部121与第一安装孔61的内侧壁之间的第二种咬紧方式，如图10-图11所示，沿第一转动部121的横向观察方向上，第一转动部121沿第一预定直线方向U上的两端的间距尺寸大于沿第二预定直线方向V的两端的间距尺寸。其中第一预定直线方向U与第二预定直线方向V具有一定夹角，例如为30°、60°或90°等，此处不作限定。如此使第一转动部121的横截面例如为椭圆形或腰圆形或长方形或菱形状等，第一构件6的第一安装孔61的形状及尺寸与第一转动部121的形状及尺寸相配合，即第一安装孔61的横截面呈椭圆形或腰圆形或长方形或菱形状等，以使第一转动部121能够通过间隙配合顺利插入第一安装孔61内。当外部工具驱动操作部13沿第二转动方向(通常为顺时针方向)转动一定角度时，第一转动部121在第一安装孔61内也转动相同的角度，以使第一转动部121的横截面的长度尺寸较大的两端分别移动到第一安装孔61的横截面的长度尺寸较小的两端，此时第一转动部121与第一安装孔61之间处于过盈配合，使第一转动部121与第一安装孔61的内侧壁之间产生一个咬紧力，限制第一转动部121从第一安装孔61内拔出。当需要将第一连接件1从第一构件6上拆下时，外部工具驱动操作部13沿与第二转动方向相反的方向(通常为逆时针方向)转动即可。
进一步地，为了确保第一转动部121随操作部13同步转动、以及 第一连接件1整体具有较大的结构强度，第一连接件本体、连接凸台11、操作部13及第一转动部121为金属一体件，例如采用铁质、镀锌合金或不锈钢等材质制备而成。
在本实施例1的另外一些实施方式中，操作部13的横截面面积大于第一转动部121的横截面面积，同时，操作部13的横截面面积大于第一安装孔61的横截面面积，以使第一转动部121能够全部插入第一安装孔61并与第一安装孔61的内壁相互咬紧时，操作部13的端部抵接至第一构件6的表面，利用操作部13起到安装定位的目的，提高装配精度及便捷性。
作为安装部12与第一构件6之间的第二种连接方式，如图12-图16，安装部12包括第一膨胀体122及第二转动部123，第一膨胀体122例如呈内部中空状的圆柱体结构，第二转动部123可转动地设于第一膨胀体122的内部，第一膨胀体122的外侧壁设有至少一个第一紧固凸台122a，第二转动部123与第一连接件本体为一体成型结构，以使第二转动部123也随操作部13同步转动。当操作部13被外部工具驱动以实现转动时，第二转动部123在第一膨胀体122的内部转动一定角度，以使至少一个第一紧固凸台122a沿第一膨胀体122的径向向外膨胀，从而使至少一个第一紧固凸台122a与第一构件6的第一安装孔61的内侧壁相咬紧。
本发明实施例1的第一紧固凸台122a的数量可以为一个或多个，第一紧固凸台122a与第一膨胀体122为一体成型结构。第一紧固凸台122a及第一膨胀体122可以具有一定弹性，例如为塑料材质。此外，本实施例1的第一膨胀体122的其他结构与现有技术的预埋螺母10的结构相同，此处省略赘述。
进一步地，在本实施例1的一些实施方式中，如图15、图16所示，第一膨胀体122由多个子件拼合形成，为了防止在使用过程中第一膨胀体122发生分散现象，第一紧固凸台122a设于第一膨胀体122的一端，第一膨胀体122的另一端套设有安全筒16。其中，安全筒16 的筒径大于操作部13的直径，如此采用安全筒16包围多个子件来保证组装后的第一膨胀体122的连接稳定性。
进一步地，第二转动部123驱动第一紧固凸台122a沿第一膨胀体122径向向外膨胀的方式包括如下两种，第一种例如图12、图15、图16所示，第二转动部123为圆柱体状或圆锥体状，第二转动部123的外周侧壁设有外螺纹；第一膨胀体122内设有与第二转动部123配合连接的安装内螺纹122b；其中，沿第二转动部123插入第一膨胀体122内部的方向上，安装内螺纹122b的螺纹底径逐渐减小。当第二转动部123在第一膨胀体122内转动时，能够使第一膨胀体向外膨胀。
作为第二转动部123驱动第一紧固凸台122a沿第一膨胀体122径向向外膨胀的第二种方式，如图13、图14所示，沿第二转动部123的横向观察方向上，第二转动部123沿第三预定直线方向X上的两端的间距尺寸大于沿第四预定直线方向Y的两端的间距尺寸。其中第三预定直线方向X与第四预定直线方向Y具有一定夹角，例如为30°、60°或90°等，此处不作限定。如此使第二转动部123的横截面例如为椭圆形或腰圆形或长方形或菱形状等，第一膨胀体122内部中空部分的形状及尺寸与第二转动部123的形状及尺寸相配合，即第一膨胀体122内部中空部分的横截面呈椭圆形或腰圆形或长方形或菱形状等，以使第二转动部123能够通过间隙配合顺利插入第一膨胀体122的内部。当外部工具驱动操作部13沿第四转动方向(通常为顺时针方向)转动一定角度时，第二转动部123在第一膨胀体122的内部也转动相同的角度，以使第二转动部123的横截面的长度尺寸较大的两端分别移动到第一膨胀体122内部中空部分的横截面的长度尺寸较小的两端，此时第二转动部123在第一膨胀体122的内部为过盈配合，第二转动部123会驱动第一膨胀体122的侧壁沿其径向向外膨胀，从而带动至少一个第一紧固凸台122a膨胀并抵紧至第一安装孔61的内侧壁，增大第一膨胀体122在第一安装孔61内的滑动摩擦力，从而限制安装部12从第一安装孔61拔出，进而实现第一连接件1与第一构件6之间牢 固连接。当需要将第一连接件1从第一构件6上拆下时，外部工具驱动操作部13沿与第四转动方向相反的方向(通常为逆时针方向)转动即可。
进一步地，上述第一连接件本体在连接凸台11与安装部12之间为一体成型的刚性结构，以使连接凸台11的中心线与安装部12的中心线处于同一直线上，此时第一连接件1通常适用于第一构件6及第二构件7的连接面分别为竖直面或水平面的情况，具有较强的重力承载能力。
在一些实施方式中，当第一构件6与第二构件7相向连接并贴合的一侧均为斜面时，如图17、图18、图22所示，第一连接件本体在连接凸台11与安装部12之间具有铰接部111，连接凸台11与安装部12通过铰接部111相互转动，以使连接凸台11与安装部12形成一定夹角，夹角例如为10°、30°、65°、100°、150°、或180°等，具体根据第一构件6与第二构件7相互连接的斜面来调节连接凸台11与安装部12之间的夹角，以使安装部12固定连接于第一构件6的连接面，同时连接凸台11及连接凹槽14能够与位于第二构件7的连接面上的第二连接件2顺利连接，最后使第一构件6的连接面与第二构件7的连接面相互贴合以实现隐形性连接。
其中，本发明实施例1的操作部13相比于铰接部111更靠近于连接凸台11，以使安装部12、铰接部111、操作部13、连接凹槽14及连接凸台11依次设于第一连接件主体上。
进一步地，本发明实施例1的铰接部111可以为枢轴或铰接球或万向节结构。具体地，如图17所示，第一连接件本体在连接凸台11与安装部12之间为分离结构，即第一连接件本体分离成第一分体和第二分体，连接凸台11位于第一分体上，安装部12位于第二分体上，当铰接部111为枢轴时，第一分体与第二分体分别设有枢孔，采用销轴或圆柱体结构作为枢轴依次穿设于第一分体与第二分体的枢孔，使得第一分体与第二分体能够绕枢轴相对转动，从而使连接凸台11与安 装部12相对转动。如图18所示，当铰接部111为万向节时，万向节例如为十字轴，第一分体与第二分体分别设有转轴孔，第一分体的转轴孔套设于十字轴的第一转轴上，第二分体的转轴孔套设于十字轴的第二转轴上，使得第一分体与第二分体能够绕十字轴相对转动，从而使连接凸台11与安装部12相对转动，角度调节更为灵活，提高装配便捷性，从而使本发明实施例1的连接组件适用于两个家具板件的连接面为斜面的隐形性连接，提高家具成品的美观性。
进一步地，基于上述本发明实施例1的第一连接件1的结构，下面对本实施例1的与第一连接件1配合连接的第二连接件2的具体结构做进一步说明。
如图19、图20所示，第二连接件2可以为圆柱体或圆锥体或球体结构，第二构件7的底部(或顶部)开设有容纳第二连接件2的第二安装孔71，第二连接件2通过间隙配合安装于第二安装孔71内并在第二安装孔71内可转动，以使第二连接件2直接连接于第二构件7上，同时第二连接件2能够在释放位置和锁定位置之间的转动方向上转动。第二连接件2的侧壁开设有插槽21，插槽21的至少一个内侧壁设有夹紧臂22；当第二连接件2处于释放位置时，连接凸台11及连接凹槽14从插槽21的开口插设于插槽21内；当第二连接件2处于锁定位置时，夹紧臂22限制连接凸台11从插槽21内拔出。
如图34所示，为了实现第一构件6与第二构件7之间隐形式连接的目的，第二连接件2完全设于第二安装孔71内，因此第二构件7的侧壁开设有与第二安装孔71连通的安装通道72，以使连接凸台11及连接凹槽14穿过安装通道72后以插入第二连接件2的插槽21内，此时第一连接件本体的一部分及操作部13也插入安装通道72内，从而使第一连接件1部分隐匿在第二构件7的内部，此时第一构件6的表面与第二构件7的表面相互贴合以实现隐形式连接，用户在第一构件6或第二构件7的外部看不到第一连接件1及难以看到第二连接件2。
进一步地，本发明实施例1的夹紧臂22沿插槽21的开口边缘设 置，夹紧臂22的数量可以为一个或两个，通常情况下，夹紧臂22的数量为两个时，两个夹紧臂22分别设有插槽21的相对两内侧，通过两个夹紧臂22分别设于连接凹槽14内，从而限制连接凸台11从插槽21中拔出。
在本实施例1的一些实施方式中，第二连接件2为金属材质，例如铁质或钢质或镀锌合金材质，结构强度大，满足较大的承载要求。
为了驱动第二连接件2在释放位置和锁定位置之间转动，第二连接件2的端部设有用于驱动第二连接件2转动的驱动部23，驱动部23可以为凹槽或凸点结构。在一些实施方式中，如图19、图20所示，驱动部23为凹槽结构，例如为一字槽或十字槽或内六角槽等，凹槽结构的驱动部23能够确保第二连接件2全部设于第二安装孔71，达到隐形目的，然后采用工具插入驱动部23内以驱动第二连接件2在第二安装孔71内发生转动。
进一步地，本发明是实施例1的第二连接件2为偏心轮结构，即插槽21呈偏心结构。当第二连接件2在释放位置时，此时连接凸台11及连接凹槽14插入插槽21的深度较大；当第二连接件2在锁定位置时，连接凸台11插入插槽21的深度较小，以使夹紧臂22卡设于连接凹槽14中，此时夹紧臂22抵紧连接凸台11以限制连接凸台11从插槽21中拔出。基于上述本实施例1的第一连接件1的连接凸台11的直径尺寸为3-5.3mm，本发明实施例1的第二连接件2的直径尺寸为6-11.5mm，例如6mm、7mm、8.5mm、10mm、11.5mm等，如此本发明实施例1的第二连接件2的直径尺寸远小于现有技术中偏心轮的直径尺寸，从而使第二安装孔71的孔径较小，提高第二连接件2在第二构件7上隐形性。
基于上面本发明实施例1的连接组件的结构，可以通过本发明实施例1的连接组件来实现第一构件6与第二构件7之间的隐形式连接，以形成一个连接系统，如图21、图22所示，连接系统包括第一构件6、第二构件7、第一连接件1及第二连接件2；其中第一构件6开设有第 一安装孔61，安装部12插入第一安装孔61内；当操作部13转动一定角度时，安装部12与第一安装孔61的内侧壁相咬紧；第二构件7的底部开设有第二安装孔71，第二构件7的侧壁开设有连通至第二安装孔71的安装通道72，第二连接件2可转动地设于第二安装孔71内；当第二连接件2处于释放位置时，连接凸台11及连接凹槽14通过安装通道72插入第二连接件2的插槽21内，且操作部13位于安装通道72内；当第二连接件2处于锁定位置时，夹紧臂22限制连接凸台11从插槽21内拔出，从而使第一构件6与第二构件7通过第一连接件1与第二连接件2实现隐形性连接。
其中，本发明实施例1的连接系统的第一连接件1与第一构件6的具体安装方式、及第二连接件2与第二构件7之间的具体安装方式分别请参考上面描述，此处省略赘述。
在本实施例1的一些实施方式中，如图34所示，安装通道72包括相互连通的第一级子通道721及第二级子通道722，第一级子通道721的横截面面积与连接凸台11的横截面面积相适配，第二级子通道722的横截面面积与操作部13的横截面面积相适配。当操作部13的横截面面积大于连接凸台11的横截面面积时，安装通道72为变径通道，安装通道72靠近第二安装孔71的部分(即第一级子通道721的横截面面积)小于安装通道72靠近其开口的部分(即第二级子通道722的横截面面积)，以使第一连接件1更能适配插入安装通道72，对第二构件7的载荷能力更强，提高第一构件6与第二构件7之间的连接牢固性。
实施例2
针对两个家具板件采用现有技术中的二合一连接件或三合一连接件进行连接后存在隐形性较低的技术问题，如图23-图28所示，本发明实施例2公开一种第一连接件1，其与上述实施例1的第二连接件2配合组成连接组件，第一构件6与第二构件7通过本发明实施例2的 连接组件实现隐形式连接。其中，本发明实施例2的第一连接件1的结构与上述实施例1的第一连接件1的结构不同，其不同之处在于：本实施例2的第一连接件1包括第一连接件本体，第一连接件本体的至少一部分在外力驱动下进行滑动，从而使第一连接件本体的安装部12与第一构件6牢固连接，从而使第一连接件1安装于第一构件6上。
具体地，下面针对本实施例2的第一连接件1的具体结构作详细说明。
如图23-图27所示，本实施例2的第一连接件1包括第一连接件本体，第一连接件本体的一端凸出形成有连接凸台11，第一连接件本体的另一端设有安装部12，安装部12用于锁紧在第一构件6的第一安装孔61内，第一连接件本体在连接凸台11与安装部12之间的位置处固定设有驱动外螺纹部17，驱动外螺纹部17配合连接有带内螺纹的操作部13，操作部13与连接凸台11相对间隔设置以形成有连接凹槽14，操作部13用于被外部工具驱动以带动第一连接件本体的至少一部分滑动；其中，操作部13的外侧壁上具有至少一个操作平面或操作孔或操作凸点或操作凹槽，或，操作部13的横截面适配于套筒的横截面。
需要说明的是，本实施例2的连接凸台11的结构与上述实施例1的连接凸台11的结构完全一样，其具体结构及工作原理可参考上述实施例1的描述，此处省略赘述。例如当连接凸台11的横截面呈圆形时，连接凸台11的直径尺寸为3-5.3mm，例如为3mm、3.5mm、4.0mm、4.2mm、4.5mm、5mm、5.3mm等。
本实施例2的操作部13的具体结构与上述实施例1的操作部13结构相似，但不同之处在于：本实施例2的操作部13与第一连接件本体之间是相对分离，即操作部13能够从第一连接件本体上拆卸。第一连接件本体在连接凸台11与安装部12之间固定设有驱动外螺纹部17，例如驱动外螺纹部17一体成型于第一连接件本体上，操作部13套设于驱动外螺纹部17外并使操作部13的内螺纹与驱动外螺纹部17相互配合以实现螺纹连接，当外部工具驱动操作部13转动时，利用螺纹连 接的原理将操作部13的旋转运动转变成驱动外螺纹的直线运行，从而带动第一连接件本体的至少一部分直线滑动。
进一步地，下面针对安装部12与第一构件6的第一安装孔61之间实现牢固连接作详细说明。
如图23-图26所示，本实施例2的安装部12包括第二膨胀体124及与第一连接件本体固定连接的锥形部125，第二膨胀体124的内部形成有锥形通道124a，锥形部125滑动设于锥形通道124a内，第二膨胀体124的外侧壁设有至少一个第二紧固凸台124b；其中，当操作部13被外部工具驱动以实现转动时，锥形部125在锥形通道124a内滑动一定距离，以使至少一个第二紧固凸台124b沿第二膨胀体124的径向向外膨胀，从而使至少一个第二紧固凸台124b与第一构件6的第一安装孔61的内侧壁相咬紧。可以理解的是，锥形部125的一端横截面面积大于另一端横截面面积，例如呈圆台体状或锥形台体状等，也是可以是非锥形的突出状，只要当锥形部125在锥形通道124a内滑动后能使至少一个第二紧固凸台124b沿第二膨胀体124的径向向外膨胀即可，在此不对锥形部125的形状作特别的限制。锥形部125优选为圆台体状，锥形部125例如一体成型于第一连接件本体的一端端部，此时锥形通道124a内周壁也呈圆台状。
其中，为了使锥形部125能够顺利置于第二膨胀体124内的锥形通道124a，第二膨胀体124可以为由多个子件拼合形成，如图23-图25所示，第二膨胀体124由两个带锥形槽的子件拼合而成。第二紧固凸台124b与第二膨胀体124为一体成型结构。第二紧固凸台124b及第二膨胀体124可以具有一定弹性，例如为塑料一体件。进一步地，为了确保第二紧固凸台124b能够顺利沿第二膨胀体124的径向向外膨胀，第二膨胀体124上位于第二紧固凸台124b的位置处开设有连通至锥形通道124a的形变间隙，形变间隙用于提高第二膨胀体124的变形能力。
当本发明实施例2的第一连接件1安装于第一构件6上时，将第 二膨胀体124通过间隙配合置于第一构件6的第一安装孔61内，外部工具驱动操作部13沿第五方向(通常为顺时针方向)转动时，通过操作部13的内螺纹与驱动外螺纹部17之间的螺纹连接以使第一连接件本体的一部分沿直线滑动，带动锥形部125在锥形通道124a内滑动，使得锥形部125的横截面面积较大的一端逐渐往锥形通道124a的横截面面积较小的一端滑动，从而使锥形部125与锥形通道124a内周壁之间逐渐变成过盈配合，以使锥形部125抵紧至锥形通道124a的内壁，从而使第二膨胀体124的外周壁逐渐径向向外膨胀，进而以使至少一个第二紧固凸台124b也沿第二膨胀体124的径向向外膨胀并与第一构件6的第一安装孔61的内侧壁相咬紧，实现安装部12与第一构件6的第一安装孔61之间实现牢固连接。当需要将第一连接件1从第一构件6上拆除时，外部工具驱动操作部13沿与第五方向的相反方向(通常为逆时针方向)转动时，锥形部125的横截面面积较大的一端逐渐往锥形通道124a的横截面面积较大的一端滑动，使锥形部125与锥形通道124a的内周壁之间逐渐变成间隙配合，从而使第二膨胀体124的外周壁逐渐径向向内收缩，进而以使第二紧固凸台124b也沿第二膨胀体124的径向向内收缩并与第一构件6的第一安装孔61的内侧壁相分离，从而使安装部12能够轻松从安装孔拔出，进而使第一连接件1与第一构件6拆分。
在一些实施方式中，为了使外部工具更为稳定地驱动操作部13(转动以带动第一连接件本体的一部分沿直线方向滑动，操作部13的内螺纹的横截面面积大于连接凸台11的横截面面积，如此可使操作部13能够穿过连接凸台11安装到驱动外螺纹部17上，从而提高第一连接件1的装配效率。此外，当外部工具为套筒扳手时，如此操作部13的内螺纹的横截面面积大于连接凸台11的横截面面积能够确保套筒穿过连接凸台11后套设于操作部13上，确保套筒扳手顺利驱动操作部13转动。
进一步地，在本实施例2的一些实施方式中，如图26所示，当第 二膨胀体124由多个子件拼合形成时，为了防止在使用过程中第二膨胀体124发生分散现象，第二紧固凸台124b设于第二膨胀体124的一端，第二膨胀体124的另一端套设有保护筒110。其中，保护筒110的筒径大于驱动外螺纹部17，如此采用保护筒110包围多个子件来保证构成的第二膨胀体124的连接稳定性。
进一步地，上述本实施例2的第一连接件本体在连接凸台11与安装部12之间为一体成型的刚性结构，以使连接凸台11的中心线与安装部12的中心线处于同一直线上，此时第一连接件1通常适用于第一构件6及第二构件7的连接面分别为竖直面或水平面的情况，具有较强的重力承载能力。
在一些实施方式中，当第一构件6与第二构件7相向连接并贴合的一侧均为斜面时，如图27所示，本实施例2的第一连接件本体在连接凸台11与安装部12之间具有铰接部111，连接凸台11与安装部12通过铰接部111相互转动，以使连接凸台11与安装部12形成一定夹角，夹角例如为10°、30°、65°、100°、150°、或180°等，具体根据第一构件6与第二构件7相互连接的斜面来调节连接凸台11与安装部12之间的夹角，以使安装部12固定连接于第一构件6的连接面，同时连接凸台11及连接凹槽14能够与位于第二构件7的连接面上的第二连接件2顺利连接，最后使第一构件6的连接面与第二构件7的连接面相互贴合以实现隐形性连接。
其中，本发明实施例2的操作部13相比于铰接部111更靠近于安装部12。此外，本实施例2的铰接部111的结构及工作原理请参考上述实施例1的铰接部111的描述，此处省略赘述。
基于本发明实施例2的连接组件的结构，如图28所示，可以通过本发明实施例2的连接组件来实现第一构件6与第二构件7之间的隐形式连接，以形成一个连接系统，其中，本实施例2的第一连接件1与第二连接件2组成的连接系统请参考上面实施例1的连接系统的描述，此处省略赘述。
实施例3

其中，本发明并不限制连接凸台11及连接凹槽14的形状，例如连接凸台11是可以呈圆形或方形或其它不规则形状，连接凹槽14可以是环形凹槽状或方形槽或V型槽等。在一些实施方式中，如图29所示，本实施例3的连接凸台11呈扁平的方形状，连接凹槽14呈V形槽状，且连接凹槽14的数量为两个，两个连接凹槽14对称设于第一连接件主体的两侧，相应地，连接通道31的横截面的形状与连接凸台11的形状相同，以使连接凸台11顺利插入连接通道31中。
本发明实施例3的第三连接件3的其他结构与现有技术的四合一连接件的销件结构相同，此处省略赘述。
基于本发明实施例3的连接组件的结构，可以通过本发明实施例3的连接组件来实现第一构件6与第二构件7之间的隐形式连接，以形 成一个连接系统，如图31-图33所示，连接系统包括第一构件6、第二构件7、第一连接件1及第三连接件3；其中，第一构件6开设有第一安装孔61，安装部插入第一安装孔61内；当操作部转动一定角度时，安装部与第一安装孔61的内侧壁相咬紧；第二构件7的底部开设有第二安装孔71，第二构件7的侧壁开设有连通至第二安装孔71的安装通道72，第三连接件3插设于第二安装孔71内并使连接通道31与安装通道72相连通；连接凹槽14的至少一部分穿过安装通道72以插设于连接通道31与连接孔32相连通的位置处，且操作部位于安装通道72内；螺纹紧固件5螺纹连接于连接孔32内，且螺纹紧固件5的一端插入连接凹槽14内。
其中，本发明实施例3的第一连接件1与第一构件6之间的安装方式分别请参考上述实施例1或实施例2的第一连接件1与第一构件6之间的安装方式，此处省略说明。
