40的示意图, 图 2是根据本实用新型实施例的优选防掉落装置的整体示意图, 如图 1 和 2所示, 该连接件 40包括: 第一孔 42, 与防掉凸台 60的横截面相适配, 设置为将连接件 40可旋转地嵌套在 防掉凸台 60上, 其中, 该防掉凸台 60固定在设备 70上; 至少一个第二孔 44, 设置为可旋转地嵌套螺钉 (10); 至少一个连接部 46, 该连接部 46的两端分别连接至第一孔 42和第二孔 44。优选 地, 该连接件 40可以是弹性件。 本实施例通过上述部件,通过第一孔 42与设备 70上的防掉凸台 60的嵌套,将连 接件 40固定在设备 70上, 并通过连接件 40上的至少一个第二孔 44, 将螺钉 10嵌套 在连接件 40中, 从而使得螺钉 10在使用过程中难以从连接件 40中脱出, 实现了防掉 落功能, 并且, (由于连接件 40嵌套固定在设备 70上, 从而使得在螺钉 10的使用过 程中, 不会由于连接件 40的颤动导致螺钉 10跟随连接件 40旋转, 从而防止了螺钉 10的旋转和脱落。 解决了相关技术中防掉落方案操作不便, 螺钉在使用的过程中掉落 的问题, 使螺钉使用过程操作方便且安全性强。 优选地, 图 3是根据本实用新型实施例的组合螺钉优选示意图, 如图 3所示, 上 述螺钉 10可以是组合螺钉, 该组合螺钉包括单独的螺钉 12和弹簧垫圈 30。 图 3a根 据本实用新型实施例的组合螺钉优选示意图二, 与图 3的不同之处在于, 该组合螺钉 包括单独的螺钉 12和弹簧垫圈 30及平垫圈 31。 作为一种优选实施方式, 参考图 1和图 2所示, 上述连接部 46可以呈圆弧形。通 过这种方式, 在螺钉 10沿连接件 40平面的垂直方向移动时, 可以将加在连接部 46 上的垂直方向的力扩散到该连接部 46的两端,从而能够防止连接部 46发生直接折弯, 提高了连接件 40的使用寿命。 优选地, 上述第一孔 42可以为腰型孔, 上述第二孔 44也可以为腰型孔。 作为一种优选实施方式, 还可以在上述每个第二孔 44中分别嵌套一个轴套 20。 图 4是根据本实用新型实施例的优选轴套 20的示意图,图 5是根据本实用新型实施例 的优选连接件安装示意图, 如图 4和 5所示, 轴套 20可以通过第二孔 44嵌套在连接 件 40上, 该轴套 20靠近设备 70—端的外半径大于螺钉孔 44的半径, 该轴套 20可以 固定在螺钉 10上, 以防止螺钉 10从连接件 40中脱落。 通过这种方式, 由于轴套 40 嵌套在第二孔 44中, 并且轴套 20靠近设备 70—端的外半径大于第二孔 44的半径, 从而使得轴套 20很难从连接件中脱出, 而且轴套 20又固定在螺钉 10上, 使螺钉 10 在使用过程中更加难以从连接件 40中脱出, 提高了防掉落效果。 并且由于轴套 20的 存在, 使得连接件 40与螺钉 10的表面实现了脱离, 从而使得连接件 40与螺钉 10在 转动过程中不会相互跟随, 并且连接件 40可以针对多种型号的螺钉 10实现防掉落功 能, 避免了连接件 40需要单独设计, 提高了连接件 40的适用范围。 优选地,参考图 4和图 5所示,在轴套 20通过第二孔 44嵌套在连接件 40上的情 况下, 轴套远离设备 70—端的外半径能够延展至大于第二孔 44的半径。 通过这种方 式, 使螺钉 10无论在向上移动还是向下移动的过程中, 均不会从连接件 40中脱出, 进一步提高了防掉落效果。 为了实现轴套 20在螺钉 10上的固定,本实施例中给出了如下两种优选实施方式: 方式一, 可以在轴套 20的内壁设置螺纹, 从而使轴套 20通过螺纹旋转至螺钉 10 的无螺纹部位, 起到固定位置的效果。 方式二, 也可以不在轴套 20的内壁设置螺纹, 例如, 可以在螺钉 10的加工过程 中, 先将轴套 20套在螺钉 10的无螺纹部分, 然后再对螺钉 10进行螺纹加工, 从而将 轴套 20固定在螺钉 10的无螺纹部位, 同样也能够起到固定位置的效果。 在本实施例中还提供了一种防掉落装置, 参考图 2所示, 该防掉落装置包括上述 连接件 40和防掉凸台 60, 连接件 40包括: 第一孔 42, 与防掉凸台 60的横截面相适 配, 设置为将连接件 40可旋转地嵌套在防掉凸台 60上; 至少一个第二孔 44, 设置为 将螺钉 10可旋转地嵌套在连接件 40中; 至少一个连接部 46, 该连接部 46的两端分 别连接至第一孔 42和第二孔 44; 防掉凸台 60的一端固定在设备 70上, 设置为将连 接件 40固定至设备 70上。 本实施例通过上述部件,通过第一孔 42与设备 70上的防掉凸台 60的嵌套,将连 接件 40固定在设备 70上, 并通过连接件 40上的至少一个第二孔 44, 将螺钉 10嵌套 在连接件 40中, 从而使得螺钉 10在使用过程中难以从连接件 40中脱出, 实现了防掉 落功能, 并且, (由于连接件 40嵌套固定在设备 70上, 从而使得在螺钉 10的使用过 程中, 不会由于连接件 40的颤动导致螺钉 10跟随连接件 40旋转, 从而防止了螺钉 10的旋转和脱落。 解决了相关技术中防掉落方案操作不便, 螺钉在使用的过程中掉落 的问题, 使螺钉使用过程操作方便且安全性强。 并且, 由于防掉凸台 60的存在, 使得 连接件 40与设备 70之间存在一定空间,从而避免了连接件 40存在卡死或过紧的情况, 进一步方便了螺钉 10安装过程中的操作。 优选地, 防掉凸台 60可以通过紧固的方式固定在设备 70上, 或者也可以与设备 70—体加工形成。 这种方式易于实现。 在实施过程中, 将连接件 40嵌套在防掉凸台 60上的方式有很多种, 例如, 由于 连接件 40是弹性部件,可以将防掉凸台 60远离设备 70—端的端口处的半径设置成略 大于第一孔 42的半径, 这样, 在用户加力将连接件 40嵌套至防掉凸台 60上后, 连接 件 40不易再从该端口处脱出, 实现了将连接件 40嵌套在防掉凸台 60上的效果,但是 这种方式会随着连接件 40弹性性能的不同而导致嵌套不便。在本实施例中还提供了另 一种优选实施方式, 如图 2所示, 防掉凸台 60呈柱状, 在将连接件 40套入防掉凸台 60上后, 将固定件 50在该防掉凸台 60远离设备 70的一端固定, 由于固定件 50上设 置有环形凸沿, 该凸沿的半径大于第一孔 42的半径, 因此在将固定件 50固定完成后, 也能够实现将连接件 40嵌套在防掉凸台 60上的效果, 并且这种嵌套方式不会因为连 接件 40的弹性性能不同而导致连接件 40无法嵌套进防掉凸台 60中,提升了本方案的 适用范围。 其中, 该固定件 50可以是螺钉、 铆钉等。 下面结合优选实施例进行说明, 以下优选实施例结合了上述实施例及其优选实施 方式。 实施例一 本优选实施例提供了一种螺钉的防掉落方案, 例如在高空中对零件安装时避免螺 钉的掉落的情况, 当然也可以扩展到其他领域相关方面的使用。 该螺钉防掉方案通过轴套的转接解决了连接件与螺钉配合处在螺钉打紧时的转 动, 通过将连接件直接套设在设备上设计的防掉凸台之上, 解决高空中零件安装时螺 钉掉落的问题。 同时该方案提高了安装过程中的简便性和可靠性。 该螺钉防掉方案可以包括: 组合螺钉 10 (包括单独的螺钉 12和弹簧垫圈 30)、轴 套 20、 连接件 40、 固定件 50。 其中, 弹簧垫圈 30安装在螺钉 12上, 组成组合螺钉 10; 轴套 20安装在组合螺钉 10上, 并与连接件 40的一端装配; 连接件 40的另一端 直接套设在设备 70的防掉凸台 60上, 然后固定件 50固定在设备 70上的防掉凸台 60 上, 这样就实现了组合螺钉 10的防掉功能。 通过轴套 20将组合螺钉 10与连接件 40 连接的方式, 可以防止组合螺钉 10打紧的过程中连接件 40的旋转。 连接件 40可以为弹性件(例如, 塑胶件), 其一端的第二孔套在轴套 20上凸缘的 位置, 然后对轴套 20的凸缘端进行扩口, 防止连接件 40脱落。连接件 40上可以设置 多个与轴套 20第二孔 44, 用以实现不同个数螺钉的防掉方案。 连接件 40与轴套 20第二孔 44的孔径以及与固定件 50第一孔 42的孔径可以根据 需要增大或设置成为腰型孔, 使连接件 40套设到防掉凸台后, 组合螺钉 10可以活动 的空间更大, 保证安装操作更顺畅。 连接件 40上连接第二孔之间的部分 (即上述连接部 46) 可以设置成圆弧型, 这 样在固定件 50和组合螺钉 10都安装后, 能够有效避免连接件 40发生直接折弯。 轴套 20与组合螺钉 10配合的内壁上可以设置螺纹,螺纹尺寸同组合螺钉 10的螺 纹规格, 装配时, 旋过组合螺钉 10的螺纹部分到光杆部分, 能防止轴套的脱落。 轴套 20与组合螺钉 10配合的内壁上也可以不设计螺纹, 例如, 在组合螺钉 10的螺纹加工 之前, 进行轴套 20与组合螺钉 10的装配, 然后再进行组合螺钉 10的螺纹加工, 从而 实现轴套 20不脱落。 固定件 50固定连接件 40的一端在设备的防掉凸台 60之上, 固定件 50可以采用 螺钉、 铆钉等, 形式多样。 采用螺钉防掉方案方案能够具有以下的进步和效果: 安装维护方便; 结构简单, 易操作; 易生产, 成本低廉; 通用性高。 实施例二 如图 2所示, 轴套 20通过螺纹或其它方式实现与组合螺钉 10的装配, 保证装配 后轴套 20不会脱落。 连接件 40上另外一端的第一孔 42套在设备上设置的防掉凸台 60上, 然后将固定件 50固定在防掉凸台 60之上, 防止连接件 40从该端脱出, 这样 就实现了组合螺钉 10在拆卸时的防脱落设计。 如图 3所示,螺钉 12、弹簧垫圈 30形成组合螺钉 10,螺钉 12上设置有一段光杆, 光杆上装配弹簧垫圈 30。或者如图 3a所示, 螺钉 12、 弹簧垫圈 30及平弹垫 31形成组 合螺钉 10, 螺钉 12上设置有一段光杆, 光杆上装配弹簧垫圈 30及平弹垫 31。 如图 5所示,将连接件 40—端的第二孔 44套在轴套 20上凸缘的位置,然后对轴 套 20的凸缘端进行扩口, 防止连接件 40脱落。 一个连接件 40可以设计与多个轴套 20进行配合, 用以实现多个螺钉防掉的需求。 如图 4所示,轴套 20可以设置成带凸缘的结构, 依据与组合螺钉 10的配合形式, 轴套 20中间的过孔可以设计成有螺纹结构, 也可以设计成无螺纹结构。 如图 1所示, 连接件 40, 其上与轴套 20第二孔 44的孔径以及与固定件 50第一 孔 42的孔径根据需要可以增大或设置成腰型孔,这样有利于在套设到防掉凸台 60后, 使组合螺钉 10有更大的活动空间。连接件 40上第二孔之间的部分可以设置成圆弧型, 防止组合螺钉 10安装后连接件 40发生直接折弯。另外,连接件 40的材质也可以更换 为其他有弹性的材料。 实施例三
如图 4所示, 轴套 20可以设置成不带凸缘的结构, 依据与组合螺钉 10的配合形式, 轴套 20中间的过孔可以设计成有螺纹结构, 也可以设计成无螺纹结构。 如图 3所示, 螺钉 12、 弹簧垫圈 30形成组合螺钉 10, 螺钉 12上设置有一段光杆, 光 杆上装配弹簧垫圈 30。 或如图 3a所示, 螺钉 12、 弹簧垫圈 30及平垫圈 31形成组合螺钉 10, 螺钉 12上设置有一段光杆, 光杆上装配弹簧垫圈 30及平垫圈 31。 图 6是根据本实用新型实施例的优选连接件安装示意图二, 如图 6、 图 2所示, 将连接 件 40—端的第二孔 44套在组合螺钉 10的光杆部分, 然后将轴套 20通过螺纹或其它方式 实现与组合螺钉 10的装配, 保证装配后轴套 20不会脱落。 然后将连接件 40上另外一端的 第一孔 42套在设备上设置的防掉凸台 60上, 然后将固定件 50固定在防掉凸台 60之上, 防止连接件 40从该端脱出, 这样就实现了组合螺钉 10在拆卸时的防脱落设计。 以上所述仅为本实用新型的优选实施例而已, 并不用于限制本实用新型, 对于本 领域的技术人员来说, 本实用新型可以有各种更改和变化。 凡在本实用新型的精神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本实用新型的保护范围 之内。
