 本发明的最佳实施方式
本发明的实施方式
下面结合附图和实施例对本实用新型作进一步详细的说明：
如图1，图2，图3所示，一种门锁，包括把手复位装置和离合复位装置；把手复位装置包括把手1、锁面2、蜗簧3、定位片4、转圈5，把手1、蜗簧3、定位片4、转圈5同心装配在锁面2上的大孔21内，把手1、蜗簧3、定位片4、转圈5可绕大孔21的中心轴旋转。离合复位装置包括装配在转圈5内的离合器组件7，装配在锁面2上的小孔22内的离合复位齿轮组8；所述离合器组件7上设有可以伸缩的执行销72，转圈5上设有第一凹槽52，执行销72与第一凹槽52配合。
所述把手1上设有凹槽、卡簧槽11，转圈5上设有凸台，转圈5上的凸台嵌入把手1上的凹槽中，形成把手1和转圈5的嵌合结构，转圈5可以和把手1互相驱动；卡簧6卡入卡簧槽11内，从而可以很好的把把手1和转圈5固定起来。
如图4所示，转圈5上设有第一凸块51，蜗簧3上设有第一触角31、第二触角32，锁面2上设有第二凸块23，第二凸块23上设有第一挡边231、第二挡边232，第一触角31与第一挡边231相抵，第二触角32与第四挡边232相抵，第一触角31和第二触角32同时也卡装在第一凸块51的两边。
所述离合复位齿轮组8包括第一复位块81、第二复位块82、复位簧83，复位簧83套装在第二复位块82的内部，第二复位块82又套装在第一复位块81的内部，第一复位块81、第二复位块82、复位簧83绕同一中心轴旋转；锁面2上的小孔22内设有第三凸块221，第二复位块82内设有第二凹槽821，第三凸块221装配在第二凹槽821内，实现第三凸块221对第二复位块82的定位作用；所述离合复位装置是通过离合器组件7上的第一齿轮71和第一复位块81上的第二齿轮811的连接，实现离合器组件7和离合复位齿轮组8之间的传动。
执行销伸出离合器组件外部
如图5所示，为执行销72伸出离合器组件7外部时，右开门状态结构示意剖面图。当执行销72伸出离合器组件7外部时，转圈5可以带动离合器组件7一起旋转；在外力作用下下压把手1，由于把手1和转圈5被紧固在一起，所以转圈5可随把手1一起逆时针旋转；当转圈5随把手1一起逆时针旋转时，蜗簧3上的第一触角31由于受第一挡边231的限制静止不动，第二触角32随转圈5一起逆时针旋转，从而使蜗簧3产生逆时针的周向力；此时，转圈5可以带动离合器组件7一起逆时针旋转；与此同时，离合器组件7逆时针转动带动离合复位齿轮组8顺时针转动；离合复位齿轮组8顺时针转动时，对复位簧83的第三触角831施加顺时针的周向力，迫使第三触角831随第一复位块81一起顺时针转动， 而此时锁面2上的小孔22内的第三凸块221装配在第二复位块82上的第二凹槽821内，从而起到对第二复位块82的定位作用，所以第二复位块82不随复位簧83一起顺时针转动，且第二复位块82上的第三挡边822与复位簧83上的第四触角832相抵，从而使复位簧83周向压缩，产生逆时针的周向回复力。
当作用于把手1 上的外力消失时，蜗簧3产生顺时针的周向回复力，迫使第二触角32顺时针自动复位，第二触角32反向驱动第一凸块51，使转圈5一起顺时针旋转复位；与此同时，复位簧83产生逆时针的周向回复力反作用与第一复位块81，使第一复位块81逆时针旋转复位，再通过第二齿轮811和第一齿轮71的齿轮传动使离合器组件7顺时针复位到原始位置，如图4所示。
执行销缩进离合器组件内部
如6，图7所示，当执行销72缩进离合器组件7内部时，转圈5不能带动离合器组件7一起转动，即不能开门，保持锁门状态。在外力作用下下压把手1，由于把手1和转圈5被紧固在一起，所以转圈5可以随把手1一起逆时针旋转；当转圈5随把手1一起逆时针旋转时，蜗簧3上的第一触角31由于受到第一挡边231的限制静止不动，第二触角32随转圈5一起逆时针旋转，从而使蜗簧3产生逆时针的周向力。
当作用于把手1上的外力消失时，蜗簧3产生顺时针的周向回复力，迫使第二触角32顺时针自动复位，第二触角32反向驱动第一凸块51，使转圈5一起顺时针旋转复位。
以上所述实施例仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但不能因此而理解为对本实用新型专利范围的限制；应当指出的是，对于本领域的技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些变形和改进都属于本实用新型的保护范围；因此，凡跟本实用新型权利要求范围所作的等同变换与修饰，均应落在本实用新型权利要求的保护范围之内。
