参见图1至图4,本申请一实施例提供了一种轴锁,用于对第一零件50和第二零件60进行锁定,所述第一零件50和所述第二零件60相对活动,所述轴锁包括安装组件10、锁芯组件20、锁定结构30和弹性组件40,所述安装组件10固定连接于所述第一零件50,所述锁芯组件20活动连接于所述安装组件10,所述锁定结构30设置于所述第二零件60,所述锁定结构30与所述锁芯组件20适配,所述弹性组件40与所述锁芯组件20连接;
其中,所述弹性组件40带动所述锁芯组件20自所述第一零件50朝向 所述第二零件60的方向移动,或带动所述锁芯组件20背离所述第二零件60;
在所述轴锁将所述第一零件50相对于所述第二零件60锁定的情况下,所述锁芯组件20自所述第一零件50朝向所述第二零件60的方向移动,且所述锁芯组件20的移动距离越长,所述锁芯组件20与所述锁定结构30之间的间隙越小。
在本申请的实施例中,轴锁的设置用于对第一零件50和第二零件60进行锁定,使可以进行相对活动的第一零件50和第二零件60暂时进入无法相对活动的状态。其中,安装组件10为轴锁的安装主体,用于安装锁芯组件20和弹性组件40。锁芯组件20在安装组件10的配合下,安装于第一零件50,锁定结构30设置于第二零件60,锁芯组件20的设置用于配合锁定结构30实现对第一零件50和第二零件60进行锁定。弹性组件40的设置可以使锁芯组件20保持在锁定状态或者保持在解锁状态,在锁芯组件20与锁定结构30相互适配的情况下,此时锁芯组件20将处于锁定状态,在弹性组件40的作用下,锁芯组件20自第一零件50朝向第二零件60的方向移动,这样可以使锁芯组件20与锁定结构30的配合更加紧密。在锁芯组件20的移动距离越长,锁芯组件20与锁定结构30之间的间隙越小时,可以通过弹性组件40的作用使锁芯组件20和锁定结构30之间的间隙趋于消失,这样可以尽可能地消除锁芯组件20和锁定结构30之间的虚位,进而可以在第一零件50和第二零件60进入锁定状态后,减少相对活动的余量,不会出现晃动等情况,使锁定地更加稳定。本申请的实施例具有可以使第一零件50和第二零件60锁定后,虚位更小,锁定更加稳定,不容易出现相对晃动的有益效果。
需要说明的是,本实施例中的活动包括滑动或转动中的至少一者。也就是说,第一零件50和第二零件60的相对活动,可以使相对滑动、相对转动,或者滑动和转动同时存在。
需要说明的是,锁定结构30可以设置为不同位置的多个,这样可以使第一零件50和第二零件60在不同的相对位置上进行锁定。
可选地,本申请实施例中,所述安装组件10包括固定连接于所述第一零件50上的安装座11,所述安装座11上开设有安装槽111,所述弹性组件40安装于所述安装槽111内,所述安装槽111的一侧开设有安装孔112,所述锁芯组件20与所述安装孔112活动连接,所述安装孔112朝向所述第二 零件60的方向贯通。
在本申请的实施例中,安装座11的设置用于承载弹性组件40和锁芯组件20,其中,安装槽111的设置用于安装弹性组件40,安装槽111的形状可以根据弹性组件40的形状进行适配;安装孔112的设置用于安装锁芯组件20,锁芯组件20至少部分地处于安装孔112内。在安装孔112朝向第二零件60的方向贯通后,可以使锁芯组件20在弹性组件40的作用下向第二零件60伸缩,进而可以与锁定结构30进行配合,实现第一零件50和第二零件60的锁定。此处的配合是指第一零件50和第二零件60的相对位置到达锁定位置后,弹性组件40带动锁芯组件20向锁定结构30的位置进行移动,进而使锁芯组件20与锁定结构30相互抵接,实现第一零件50和第二零件60的锁定。当锁定结构30设置为至少两个时,锁定位置将会有对应的至少两个。

需要说明的是,可以通过设置对应的传动机构,可以在其它方位对拨杆22进行拨动。也可以在拨杆22或传动机构上连接驱动件,实现对拨杆22的自动化控制。此处对拨杆22的控制,是对拨杆22与不同导向结构的配合进行切换,切换后将不会对拨杆22的移动造成限制。
可选地,本申请实施例中,所述拨杆22远离所述芯杆21的一端设置有拨钮23。
在本申请的实施例中,拨钮23的设置用于对拨杆22的手动拨动,使拨杆22得控制更加方便。可以在拨钮23上设置防滑结构,如粗糙面、防滑橡胶套或者一体设置的柔性胶层。
