需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。相反，当元件被称作“直接在”另一元件“上”时，不存在中间元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1和图11所示，在一个实施例中提供了一种管件接头组件10，包括连接本体11和导向套筒12，所述导向套筒12的一端能够插入管材13内，所述导向套筒12的另一端的外壁设有第一凹凸结构121，所述连接本体11的两端均能够插入所述导向套筒12，所述连接本体11的内壁设有与所述第一凹凸结构121匹配的第二凹凸结构111，当套设在所述导向套筒12上的管材13插入到位时，所述第一凹凸结构121与所述第二凹凸结构111过盈配合，且当所述导向套筒12与所述连接本体11相对转动时，所述第一凹凸结构121与所述第二凹凸结构111发生相对刮擦，产生摩擦声响。
上述提供的管件接头组件10，通过所述第一凹凸结构121和所述第二凹凸结构111的配合来判断所述管材13是否安装到位，且无需采用另外的工序去制造所述管件接头组件10，对材料的选择也没有特殊要求，具有较强的市场竞争力。具体地，在日常生活中，通过管件接头来实现管件之间的连接，上述提供的管件接头组件10包括连接本体11和导向套筒12，且所述连接本体11的两端均可插入所述导向套筒12。使用过程中，先将管材13套设到所述导向套筒12上，然后将连接有所述管材13的导向套筒12插入所述连接本体11内，当所述管材13插入到位时，如图2和图3所示，所述连接本体11内壁上的第二凹凸结构111与所述导向套筒12外壁上的第一凹凸结构121过盈配合。且当所述连接本体11与所述导向套筒12相对转动时，所述第一凹凸结构121与所述第二凹凸结构111能够发生刮擦，产生摩擦声响，以此判断所述管材13安装到位。通过这样的结构设置，避免了在管件接头组件10上另行打孔等复杂的工序，而且在连接本体11和导向套筒12上设置相应的凹凸结构对于管件接头组件10的材料也没有特殊要求，整体上提升了所述管件接头组件10的市场竞争力。
进一步地，上述管材13安装到位是指管材13插入到连接本体11内的深度 符合安装要求。具体的，可以是管材13是否有足够的长度与连接本体11重叠，也可以是所述管材13插入的深度是否满足密封等其他方面的要求。
上述提供的管件接头组件10主要通过所述第一凹凸结构121和所述第二凹凸结构111的过盈配合，当所述连接本体11与所述导向套筒12发生相对转动时过盈配合的第一凹凸结构121和第一凹凸结构121会出现相互刮擦，产生摩擦声响，通过听是否有所述摩擦声响来判断管材13是否安装到位。因此只要所述第一凹凸结构121和所述第二凹凸结构111能够在所述连接本体11和所述导向套筒12发生相对转动时，能够发生刮擦，产生摩擦声响即可，对于所述第一凹凸结构121和第二凹凸结构111的具体形状和设置位置没有过多要求。例如所述第一凹凸结构121和所述第二凹凸结构111均可是分布在相应位置的波浪形尖齿。或者所述第一凹凸结构121可以是间隔设置在导向套筒12外壁的多个凸起，所述第二凹凸结构111可以是间隔设置在连接本体11内壁的多个凸起，只要在连接本体11与导向套筒12相对转动时所述导向套筒12外壁上的多个凸起能够与所述连接本体11内壁上的多个凸起发生相对刮擦，产生摩擦声即可。
或者具体地，在一个实施例中，如图9所示，所述第一凹凸结构121包括尖角拨片，如图5和图6所示，所述第二凹凸结构111包括沿所述连接本体11内壁周向分布的波浪形尖齿。在使用过程中当所述管材13安装到位时，所述尖角拨片与所述波浪形尖齿过盈配合，且在所述连接本体11与所述导向套筒12发生相对转动时，所述尖角拨片与所述波浪形尖齿之间会发生相对刮擦，产生摩擦声响。具体地，所述尖角拨片的个数不做具体要求。例如，可以是一个，也可以是多个，只要在刮擦的过程中能够产生摩擦声响即可。进一步地，在一个实施例中，所述尖角拨片为多个，且各个尖角拨片在所述导向套筒12的外壁轴向间隔分布。通过设置多个尖角拨片去与所述波浪形尖齿发生刮擦，所产生的摩擦声响更加明显。具体地，如图9所示，所述尖角拨片为4个，间隔分布在导向套筒12外壁上。如图1和图2所示，当所述管材13安装到位时，在所述连接本体11与所述导向套筒12相对转动时，所述尖角拨片与所述波浪形尖齿刮擦，将发出哒哒哒的声响。
进一步地，在前述管件接头组件10中连接本体11的两端均能够插入所述导向套筒12，具体的可以设置一个足够宽度的第二凹凸结构111去配合从连接本体11两端插入的导向套筒12的第一凹凸结构121。或者，在一个实施例中，如图5所示，在所述连接本体11的中部轴向分布两个所述第二凹凸结构111，两个第二凹凸结构111之间设有第一凸台112，如图7和图8所示，所述导向套筒12设有所述第一凹凸结构121的端部设有倒角122。在使用过程中，从连接本体11两端插入的导向套筒12的第一凹凸结构121分别与各自相应的第二凹凸结构111配合，实现管材13是否安装到位的判断。通过这样设置两个第二凹凸结构111，且在两个第二凹凸结构111之间设置第一凸台112，可以有效防止 从连接本体11两端插入的导向套筒12之间的相互影响。且为进一步提升所述导向套筒12与所述连接本体11的配合性能，在所述导向套筒12设有所述第一凹凸结构121的端部设置倒角122，安装过程中所述第一凹凸结构121能够更加方便的插入到第二凹凸结构111中，实现两者的过盈配合。且通过将两个所述第二凹凸结构111设置在所述连接本体11的中部，使得所述连接本体11在实现连接导通作用的同时，刚性较好，提升所述管件接头组件10的使用可靠性。
进一步具体地，如图5所示，在一个实施例中，所述连接本体11的中部轴向设有两个所述波浪形尖齿，且在所述波浪形尖齿中间设有第一凸台112。通过这样的结构设计，从连接本体11两端插入的导向套筒12的第一凹凸结构121分别与相应侧的波浪形尖齿配合。在使用过程中，通过旋转管材13或者连接本体11使得所述第一凹凸结构121在所述波浪形尖齿上刮擦，发出摩擦声响，以此判断管材13安装到位。且由于管材13尺寸的误差等因素的影响，管材13插入连接本体11内达到安装标准的深度会存在一定变化，通过设计所述波浪形尖齿，所述波浪形尖齿具有一定有效宽度，能够有效避免正常误差范围内无法判断管材13是否安装到位的情况发生。
进一步地，如图1和图11所示，在所述管件接头组件10中进一步设置有第一密封圈14和密封环15，所述导向套筒12的外壁设有第一凹槽123和第二凹槽124，所述第二凹槽124位于所述第一凹槽123与所述第一凹凸结构121之间，所述第一密封圈14与所述第二凹槽124匹配，用于实现所述导向套筒12的外壁与所述连接本体11的内壁之间的密封，所述密封环15为在所述第一凹槽123内二次注塑成型的橡胶环，用于实现所述管材13的内壁与所述导向套筒12的外壁之间的密封。
通过在所述导向套筒12的外壁设置第一凹槽123，且在所述第一凹槽123内设置二次注塑成型的橡胶环。使用过程中，所述管材13套设在所述导向套筒12上时，如图4所示，所述管材13的端部会压紧在所述橡胶环上，从而有效防止由所述管材13流入所述导向套筒12内的液体从所述管材13与所述导向套筒12之间溢出，实现此方向上管材13连接组件的密封。通过在所述导向套筒12的外壁设置所述第二凹槽124，再在所述第二凹槽124与所述连接本体11的内壁之间设置所述第一密封圈14，实现所述导向套筒12的外壁与所述连接本体11的内壁之间的密封，防止由所述连接本体11的中部流向所述管材13内的液体从所述连接本体11与所述导向套筒12之间的缝隙流出，实现所述管材13连接组件另一方向上的密封。通过采用上述结构实现所述管材13连接组件的双重密封，降低液体泄漏风险，提高管件接头组件10的使用性能。
基于所述密封环15在使用过程中是需要在管材13套设到所述导向套筒12上时挤压在所述管材13的端部，其密封位置的特殊性使得一般的O型垫圈的密封效果不佳，当安装O型垫圈的凹槽较浅时，O型垫圈容易被推出凹槽，因此 为了满足使用需求，用于安装O型垫圈的凹槽的深度需要设置的较大，为满足凹槽深度需要，将使得所述导向套筒12内径变小。而如图7所示，上述结构设计中，所述密封环15通过采用的在所述第一凹槽123内二次注塑成型的橡胶环来实现所述管材13与导向套筒12之间的密封。基于所述橡胶环咬合性强，壁薄等特点。在实现上述双重密封的同时，所述导向套筒12也不会因为需要设置放置所述橡胶环的第一凹槽123而减小内径尺寸。而且通过采用所述二次注塑橡胶环，在套设所述管材13时，能够有效避免采用O型垫圈时，垫圈从相应的凹槽内偏移，造成密封失效漏水的情况发生，提高所述管件接头组件10的密封可靠性。
进一步地，为提高所述密封环15在所述第一凹槽123内的安装性能，如图8所示，所述第一凹槽123的底壁设有防滑筋125，所述防滑筋125为沿所述导向套筒12轴向分布的筋条。二次注塑成型的橡胶环会形成与所述防滑筋125相适应的形态，能够有效增强所述橡胶环在所述第一凹槽123能的稳固性，使得压紧在所述橡胶环上的管材13能够更好的密封。
进一步地，如图7和图8所示，所述导向套筒12的外壁设有倾斜凸起126，所述第一凹槽123位于所述第二凹槽124与所述倾斜凸起126之间，所述倾斜凸起126的厚度沿远离所述第一凹凸结构121的方向上逐渐减小，套设在所述导向套筒12上的管材13的内壁能够挤压在所述倾斜凸起126上。在使用过程中，所述管材13在插到所述导向套筒12上时，随着插入深度的增加，所述管材13逐渐压紧在所述倾斜凸起126上。所述管材13会随着所述倾斜凸起126厚度的增加，越来越紧的压紧在所述倾斜凸起126上，使得所述管材13能够更加可靠的插在所述导向套筒12上，实现所述管材13与所述导向套筒12之间的固定连接。
具体地，所述倾斜凸起126的个数不做限制，只要能够使得所述管材13更加可靠的插在所述导向套筒12上即可。可以是多个，也可以如图10所示，在所述导向套筒12的外壁设置四个倾斜凸起126，且所述四个倾斜凸起126均匀间隔分布。采用这样的结构设置能够使得所述管材13插在所述导向套筒12上时，各个方向上的压紧和偏移量相同，所述管材13始终与所述导向套筒12同轴，进一步增加所述管材13与所述橡胶环之间的密封性，同时保证所述管材13与所述导向套筒12和连接本体11的同轴度，提升所述管材13内液体在在所述导向套筒12与所述连接本体11之间流动的稳定性。
进一步地，如图1和图5所示，所述管件接头组件10还包括第二密封圈16，所述连接本体11的内壁设有用于实现所述第二密封圈16定位的安装位113，所述第二密封圈16能够挤压在所述连接本体11与所述管材13之间。通过在连接本体11的内壁设置所述第二密封圈16的安装位113，将所述第二密封圈16定位在连接本体11与管材13之间，来实现所述连接本体11与所述管材13之间 的密封，进一步提升所述管件接头组件10的密封性能。由所述连接本体11流向管材13内的液体会在所述第一密封圈14的作用下避免从所述连接本体11与所述导向套筒12之间溢出，而所述第一密封圈14没有阻止成功的液体将在所述密封环15和所述第二密封圈16的作用下进一步阻止其溢出到管材13组件外。通过所述第一密封圈14、第二密封圈16和密封环15的共同作用形成多道密封，提升所述管件接头组件10的密封可靠性。
进一步地，为防止插入所述连接本体11内的管材13脱落，如图1和图11所示，在所述管件接头组件10中进一步设置靠垫115、内齿垫圈116和套设在连接本体11外壁上的外壳17，所述靠垫115和内齿垫圈116依次层叠在所述连接本体11的端部，所述连接本体11的外壁设有凸缘114，所述外壳17的内壁设有紧固槽171，所述紧固槽171的一个侧壁压紧在所述内齿垫圈116上，所述紧固槽171的另一个侧壁钩挂在所述凸缘114上，所述内齿垫圈116的齿牙1161能够压紧在所述管材13的外壁上。
使用过程中，如图12所示，先将所述密封环15通过二次注塑成型的方式设置在所述第一凹槽123内，将所述第一密封圈14安装在所述第二凹槽124内。然后将所述管材13插到所述导向套筒12上，随着管材13与导向套筒12之间重叠长度的增加，所述管材13的内壁在所述倾斜凸起126的作用下逐渐涨紧，直到所述管材13插到所述导向套筒12上的端部与所述密封环15压紧，实现所述管材13与所述导向套筒12之间的紧固安装。然后再将所述第二密封圈16安装到所述连接本体11的安装位113上，依次将所述靠垫115和内齿垫圈116层叠在所述连接本体11的端部，然后利用所述外壳17内壁设置的紧固槽171将所述靠垫115和内齿垫圈116固定在所述连接本体11的端部。最后再将连接有所述管材13的导向套筒12由外至内依次通过所述内齿垫圈116、靠垫115和第二密封圈16插入所述连接本体11内，直到所述导向套筒12上的第一凹凸结构121与连接本体11上的第二凹凸结构111匹配，实现过盈配合。且通过旋转管材13或者连接本体11，所述第一凹凸结构121与所述第二凹凸结构111将发生观察，产生摩擦声响。此时所述管材13安装到位，所述内齿垫圈116的齿牙1161压紧在所述管材13的外壁上，阻止所述管材13从所述连接本体11内向外退出，提升所述管材13在所述管件接头组件10内安装连接的可靠性。且通过合理设计所述连接本体11上与所述第一密封圈14贴紧的内壁的轴向宽度，使得当所述齿牙1161压紧的管材13有正常范围内的倒退时，所述第一密封圈14始终能够实现所述连接本体11与所述导向套筒12之间的密封，进一步提高所述管材13在所述管件接头组件10内安装和使用的可靠性。
进一步地，如图11和图12所示，所述管件接头组件10还包括压套18和取管压件19，所述压套18插设在所述外壳17内，所述压套18钩在所述外壳17的内壁上，且所述压套18的前端部181与所述内齿垫圈116的齿牙1161抵 接，所述取管压件19包括弹性弯曲部191和位于所述弹性弯曲部191两端的按压部192，所述弹性弯曲部191的侧壁设有凸块193，通过控制所述按压部192将所述取管压件19向靠近所述压套18的方向按压，使得所述凸块193顶压所述压套18的后端部182，使得所述压套18的前端部181移动撑开所述内齿垫圈116的齿牙1161。
通过所述内齿垫圈116的作用，插入到位的管材13无法从所述管件接头组件10内退出。在需要取出所述管材13组件时，可以通过所述取管压件19的凸块193去抵压所述压套18的后端部182，使得所述压套18向所述连接本体11内移动，从而使得所述压套18的前端部181移动撑开能够与其抵接的齿牙1161，使所述齿牙1161释放所述管材13，然后抽出所述管材13，实现所述管材13的快速拆卸和更换。无需通过损坏管材13来实现所述管材13的拆卸，使得管材13可以重复利用，节约成本，避免不必要的浪费。
上述提供的管件接头组件10，主要通过设置第一凹凸结构121和第二凹凸结构111的配合来实现管材13是否安装到位的判断。在安装过程中，当管材13安装到位时所述第一凹凸结构121与所述第二凹凸结构111过盈配合，且当所述连接本体11与所述导向套筒12相对转动时所述第一凹凸结构121与所述第二凹凸结构111将发生相对刮擦，产生摩擦声响，以此方式判断管材13是否安装到位。无需依赖管件接头组件10的材料，也不需要复杂的制造工艺来实现，提升所述管件接头组件10的市场竞争力。
图13至图16示出了本发明另一个实施例。如图13所示，管件接头组件20包括：导向套筒22，该导向套筒22的一端插入管材24内；连接本体21，连接本体21的内壁上设置有第二凹凸结构，在本实施例中，第二凹凸结构为波浪形尖齿210；和内齿圈23。内齿圈23同心地插入到连接本体21内。导向套筒22的另一端同心地插入到连接本体21内，同时也同心地插入到内齿圈23内。如图14所示，导向套筒22的插入到连接本体21内的一端设置有第一凹凸结构。在本实施例中，第一凹凸结构为尖角拨片220。如图15所示，内齿环23的内圈设置有第三凹凸结构，且所述内齿圈的外圈设置有第四凹凸结构，在本实施例中，第三凹凸结构波浪形尖齿231，第四凹凸结构为凸棱230。
当管件接头组件20组装时，连接本体21的两端均能够插入导向套筒22和内齿圈23，其中，内齿圈23同心地插入连接本体21中，凸棱230与波浪形尖齿210过盈配合，使得内齿圈23牢固地卡接在连接本体21的内壁。应该明确的是，本实施例中凸棱230与波浪形尖齿210都是示例性的，第二凹凸结构和第四凹凸结构可以为尖角拨片、波浪形尖齿、凸棱以及其他任意合适的结构，第二凹凸结构和第四凹凸结构可以为相同的结构，也可以为不同的结构，只需满足使得第二凹凸结构和第四凹凸结构能够通过过盈配合互相连接在一起的需求即可。导向套筒同心地插入连接本体21并插入到内齿圈23中，尖角拨片220 与波浪形尖齿231之间以存在移动干涉的方式间隙配合。当导向套筒22与内齿圈23发生相对转动时，尖角拨片220与波浪形尖齿231由于存在移动干涉而发生相对刮擦，从而产生摩擦声响及震动手感，提示使用者管材已经插入到位。应该明确的是，本实施例中尖角拨片220与波浪形尖齿231都是示例性的，第一凹凸结构和第三凹凸结构可以为尖角拨片、波浪形尖齿、凸棱以及其他任意合适的结构，第一凹凸结构和第三凹凸结构可以为相同的结构，也可以为不同的结构，只需使得第一凹凸结构和第三凹凸结构能够以存在移动干涉的方式间隙配合即可。
管件接头组件20的其他结构特征与管件接头组件10相同，故不再重复描述。以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
