卡扣配合结构及分离式壳体 技术领域
本实用新型涉及机械结构领域， 尤其涉及一种卡扣配合结构及分离式壳体。 背景技术
产品壳体为分离式结构时， 需要设计相应的配合结构， 比较常见的配合结 构为螺纹连接、 螺釘连接、 卡扣连接。 对于螺纹连接的结构， 旋进和旋出比较 麻烦， 特别对于较大的壳体； 而螺釘连接， 安装和拆卸都比较复杂， 螺釘如果 拆卸次数过多， 还容易造成滑丝， 并且螺釘连接不美观； 卡扣连接为直接扣接 的结构， 壳体安装会比较筒单， 但是拆卸时会比较麻烦， 卡扣依赖于自身材料 的弹性， 如果拆卸次数过多可能造成卡扣断裂等问题。
综上所述，现有的分离式壳体的配合结构往往在安装和 /或拆卸中比较复杂， 或者受结构限制拆装次数不宜过多等， 导致对于可能需要经常拆装的壳体而言 使用比较麻烦。 实用新型内容

为详细说明本实用新型的技术内容、 构造特征、 所实现目的及效果， 以下 结合实施方式并配合附图详予说明。
请参阅图 1以及图 2, 本实施例的卡扣配合结构包括第一构件 10和第二构 件 20, 使用时， 两构件分别设置于两需要对应连接的部件上。
第一构件 10包括基座 13,从基座 13上表面向上凸伸形成卡钩部 11和凸块
部 12, 且卡钩部 11和凸块部 12之间具有一定间距， 其中凸块部 12所在的基座 13位置为一弹臂结构， 使凸块部 12在垂直方向上具有一定的弹性位移， 凸块部 12在面向卡钩部 11的一侧设置为斜面， 而背向卡钩部 11的一侧则设置为竖直 面。 基座 13侧面还设置有手柄 14, 方便人握住手柄使第一构件 10移动。
第二构件 20外形大致为块状， 其一端设置为卡扣部 21 , 另一端设置有向下 突出的平片状的骨位部 22;卡扣部 21与骨位部 22之间的距离小于卡钩部 11与 凸块部 12之间的距离； 卡扣部 21与第一构件 10的卡钩部 11适配。
如图 1所示， 第一构件 10和第二构件 20扣合时， 卡扣部 21限位于卡钩部 11内， 骨位部 22位于卡钩部 11与凸块部 12之间， 即凸块部 12的斜面侧与所 述骨位部 22相对。 当握住手柄 14按箭头指示方向移动第一构件 10使第一构件 10与第二构件 20分离后， 两者位置关系如图 2所示， 此时卡扣部 21脱离卡钩 部 11 , 而骨位部 22则越过凸块部 12到达凸块部 12的另一侧并与凸块部 12抵 接， 即凸块部 12的竖直面侧与骨位部 22相对且两者接触。
由于凸块部 12所在的基座 13具有一定弹性， 因此， 在第一构件 10移动的 过程中， 骨位部 22可以下压凸块部 12而越过凸块部 12, 凸块部 12面向卡钩部 11的一侧设置为斜面， 骨位部 22可以对凸块部 12逐步使力， 方便两者进行相 对位置关系的正常改变。 两构件分离后， 两构件所在的部件即可上下分离， 卡 钩部 11上表面设置为斜面， 则是方便在安装时卡扣部 21在下行时对第一构件 10施力，使卡钩部 11让位而最终使卡扣部 21进入卡钩部 11的钩状结构内限位 固定。
本实用新型的卡扣配合结构中， 通过卡钩部与卡扣部的配合进行扣合， 安 装方便， 而在卡钩部与卡扣部脱离后， 骨位部与凸块部相抵接形成一暂停回位 结构即卡钩部与卡扣部不再能回复卡接状态， 方便第一构件和第二构件的最终 分离。
本实用新型的卡扣配合结构可应用于上下分离的壳体中， 其中壳体包括座 体和盖体， 其中第二构件一体成型于盖体上， 可以是在盖体内壁的筋条上设置 该结构， 除了卡扣配合作用外还起到增加盖体强度的作用。 第一构件安装于座 体上， 且座体上设置有供第一构件运动的空间， 第一构件与座体之间还设有回
位弹簧。 当第一构件运动使卡钩部与卡扣部分离时， 第一构件对回位弹簧产生 挤压力而压缩回位弹簧， 而当卡钩部与卡扣部脱离， 骨位部抵接凸块部后， 骨 位部顶住凸块部， 抵消回位弹簧的回复力， 使第一构件无法运动， 产生暂停功 能； 由于此时卡扣部与卡钩部脱离， 盖体可从座体上分离， 当盖体分离后， 凸 块部失去抵接， 此时回位弹簧的回复力使第一构件返回原位。
该分离式壳体中， 由于该卡扣配合结构提供了暂停功能， 使得盖体和座体 的分离方便快捷； 而通过回位弹簧使得在盖体分离后， 第一构件可以自动回位。
当座体和盖体均为圓形结构时， 可以在座体和盖体上设计多个绕圓周分布 的卡扣配合结构， 且多个第一构件联动， 可以只在其中一个第一构件上设置手 柄， 手柄突出于座体， 这样座体上只需要设置一个用于手柄伸出的孔， 外表上 比较美观， 当通过该手柄移动第一构件时， 所有的第一构件均相应移动。 设计 多个卡扣配合结构， 可以使座体跟盖体之间在安装和分离时更加稳定。
当座体和盖体为多边形结构时， 可以只在其中一边设置该卡扣配合结构。 座体和盖体可以按照常规结构， 只需要在座体上设计与第一构件相适配的 结构即可， 由于图 1和图 2 已经清楚地示出了第一构件和第二构件的结构， 对 于壳体结构， 只需相应地将第一构件安置于座体上， 而将第二构件成型于盖体 上， 发明人认为根据图 1和图 2的结构结合文字表述已经可以清楚地表达壳体 的结构， 因此不再给出附图示意。
以上所述仅为本实用新型的实施例， 并非因此限制本实用新型的专利范围， 凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换， 或直 接或间接运用在其他相关的技术领域， 均同理包括在本实用新型的专利保护范 围内。
