电源盒安装结构 技术领域
本公开涉及一种电源盒安装结构。
背景技术
传统的洗衣机电源盒在安装时，洗衣机电源盒的两端多通过螺钉固定。但是在安装螺钉时，需要使用辅助安装工具旋拧螺钉方可将电源盒与洗衣机大框连接。这种连接方式，虽然较为简单，但是需要人工或者机械手臂将螺钉拧紧，同时需要一定的时间，耗时耗力。
或者，在电源盒和洗衣机大框中的一个上上设置卡爪，在电源盒和洗衣机大框中的另一个上设置与卡爪配合的卡槽或凸起。但是在维修过程中，将电源盒拆卸变得困难。同时卡爪与洗衣机大框/电源盒为一体式结构，拆卸时容易被损坏，不利于后期维护安装。

具体实施方式
为了使本领域技术人员更好地理解本公开的技术方案，下面结合附图并通过具体实施方式来进一步说明本公开的技术方案。
实施例1
本实施例提供了一种电源盒安装结构，如图1-5所示，该电源盒安装结构包括电源盒2和底座1。电源盒2第一侧设置有第一连接轴4，电源盒2的第二侧设置有第二连接轴5。底座设置有连接耳。电源盒2的一端通过第一连接轴4与底座的连接耳卡接，电源盒2的另一端通过第二连接轴5与固定锁扣连接后与底座上的另一连接耳卡接，从而完成电源盒2与底座1的连接。
本实施例中，连接耳分别为第二连接耳7、第一连接耳6。第一连接轴4***第一连接耳6内使电源盒的一侧被固定。第二连接耳7内***固定锁扣3且第二连接轴5伸入固定锁扣3的容纳槽31内，使电源盒2的另一侧被固定。通过上述连接关系，该电源盒2被固定在底座1上。为了使固定锁扣3在底座1振动时不会从第二连接耳7上脱落，本实施例中，固定锁扣3与第二连接耳7卡接。在另一个实施例中，固定锁扣3与第二连接耳7通过过盈配合连接。
需要注意的是，第一连接轴4长度大于第二连接轴5长度。如图3-5所示，第一连接轴4伸入第一连接耳6内，而第二连接轴5则不伸入第二连接耳7内，第二连接轴5的最大长度与电源盒安装完成后电源盒侧壁到第二连接耳7的距离相等，上述电源盒侧壁是指第二连接轴5所在的电源盒的侧壁，而非第一连接轴6所在的电源盒的侧壁。对应的，第一连接耳6厚度h应小于第二连接耳7厚度H，这样能够保证固定锁扣3固定于第二连接耳7内，且第一连接耳6不会造成材料浪费。
请参考图2、图4、图6，固定锁扣3包括锁扣本体32，锁扣本体32靠近第二连接轴5的一端开设有容纳槽31，第二连接轴5伸入容纳槽31。容纳槽31的深度应不小于第二连接轴5的长度的二分之一。可选地，容纳槽31为通槽。锁扣本体32顶部设置有弹片33，设置弹片33的目的是将固定锁扣3能够限定在第二连接耳7内。弹片33的第一端与所述锁扣本体32连接，第二端悬空设置。对应的锁扣本体32横截面为梯形结构，该种结构方便按压弹片33。第一连接耳6、第二连接耳7均包括两竖直侧壁以及分别与两竖直侧壁相连的水平顶壁，两竖直侧壁一端与底座1连接，另一端与水平侧壁连接，使第一连接耳6、第二连接耳7从外形上为门型结构。可选地，所述第一连接耳包括第一侧壁、第二侧壁以及第一顶壁，所述第一侧壁和第二侧壁均与第一顶壁大体垂直连接；第二连接耳包括第三侧 壁、第四侧壁和第二顶壁，所述第三侧壁和第四侧壁均与第二顶壁大体垂直连接。
该种结构方便连接轴、固定锁扣3***连接耳内。上述弹片33第二端还设置有按压凸起331，该按压凸起331方便操作人员按压，且在按压时不会发生打滑的情况。
由于底座1在工作中会发生振动，固定锁扣3也会随底座一起振动，长时间的振动会使固定锁扣3与第二连接耳7脱离。本实施例中弹片33顶部设置有限位凸起34，第二连接耳7的水平顶壁设置有限位槽8，安装时，将限位凸起34限制在限位槽8内使固定锁扣3不易与第二连接耳分离。
如图6所示，固定锁扣3为一体式结构。锁扣本体32底部、弹片33顶部均设置有安装凸起35。安装凸起35沿锁扣本体32长度方向设置。在固定锁扣3的底部与顶部不平整的情况下，这种设置能够使安装更方便。
安装时，先将第一连接轴4***第一连接耳6内，第二连接轴5位于第二连接耳7一侧，将固定锁扣3从第二连接耳7的另一侧***，固定锁扣3***过程中需要将弹片33按压，当弹片33上的限位凸起34位于限位槽8正下方时，释放弹片，使限位凸起34落入限位槽8内，此时安装完成。后期维护时，只需要将固定锁扣3从第二连接耳7中取出，即可完成电源盒的拆卸。
本实施例中提供的电源盒安装结构，无需使用安装工具就可完成电源盒的安装，方便省时。
本实施例中的涉及的底座是指洗衣机、干衣机、洗碗机上的电源盒的底座。
实施例2
本实施例中，与实施例1不同之处在于：
底座1的两端的连接耳均为第二连接耳，其中第一连接轴4和第二连接轴5 的长度相同，且第一连接轴4与第二连接轴5均不伸入第二连接耳7内，第一连接轴4与第二连接轴5均伸入固定锁扣3的容纳槽31内将电源盒2固定。
其他结构与实施例1中相同，在此不再赘述。
注意，以上显示和描述了本公开的基本原理和主要特征和本公开的优点。本行业的技术人员应该了解，本公开不受上述实施方式的限制，上述实施方式和说明书中描述的只是说明本公开的原理，在不脱离本公开精神和范围的前提下，本公开还会有各种变化和改进，这些变化和改进都落入要求保护的本公开范围内，本公开的要求保护范围由所附的权利要求书及其等效物界定。
