具体实施方式
为使本领域的技术人员更好地理解本实用新型的技术方案，下面结合附图对本实用新型提供的卡扣和卡扣组件进行详细描述。
第一实施例
图1为根据本实用新型的第一实施例提供的卡扣1在固定在第一固定件上时的结构示意图，图2为图1所示卡扣1的立体图，图3为第一固定件的卡孔21、22和限位孔23的结构示意图。如图1-3所示，所述卡扣1包括限位柱13、弹性部件14和至少一个卡钩11。所述弹性部件14设置在所述限位柱13的底部。在第一固定件的与所述卡钩11相对应的位置上设置有卡孔21，在所述第一固定件的与所述限位柱13相对应的位置上设置有限位孔23。
可选的是，所述第一固定件为底盘2。所述弹性部件在所述卡钩11放置于所述卡孔21附近时由于限位柱13抵靠所述底盘2而处于形变状态，从而在弹性部件的回弹方向上产生弹性作用力。所述限位柱13在所述卡扣1移动至预定位置时在所述弹性作用力的作用下落入所述限位孔23中，以使所述卡扣1固定在适当位置。所述卡钩11在所述限位柱13落入所述限位孔23中时与所述卡孔21卡合，以使所述卡扣1与所述第一固定件2固定连接。由上述卡扣的结构描述可知，在所述卡扣1与第一固定件2固定连接时没有使用一颗螺丝，因此所述 卡扣的结构简单。另外，当需要更换卡扣时，例如当安装和拆卸所述卡扣时，操作人员不需要使用专业工具，因此整个工作过程可以更加方便快捷，从而降低了人力成本和时间成本。
在本实施例中，所述卡钩的数量为两个，其中一个卡钩11设置在所述卡扣1的一端，另一个卡钩12设置在所述卡扣1的另一端。相应的是，在所述第一固定件(例如，底盘2)上设置有两个卡孔，其中一个卡孔21设置在所述底盘2的与所述卡钩11相对应的位置，另一个卡孔22设置在所述底盘2的与所述卡钩12相对应的位置。在实际应用中，所述卡钩的数量可以大于两个，多个所述卡钩分布在所述卡扣1的不同位置并且均匀分布以保证受力的均匀性。这样，所述卡扣1可以更牢固地固定在所述底盘2上。
可选的是，所述限位柱13设置在卡钩11与卡钩12之间的位置。优选的是，所述限位柱13设置在卡钩11与卡钩12的中间位置。所述限位柱13与所述限位孔23相互配合以固定所述卡扣1的位置。当所述限位柱13位于两个卡钩11和12的中间位置时，所述卡扣1受到的来自所述限位柱13的用于固定所述卡扣1的作用力更加均匀，从而使得所述卡扣1更加牢固地固定在适当位置。
在本实施例中，所述弹性部件为弹性跳板14，所述弹性跳板14的一端固定在所述卡扣1上，所述弹性跳板14的另一端形成有所述限位柱13。可选的是，所述卡钩11的自由端设置为朝向第一方向(即，安装方向)，所述第一方向与所述卡扣1在安装时的移动方向一致，从而保证所述卡钩11顺利与所述卡孔21卡合，以便将所述卡扣固定连接在所述底盘上。
图4为图1所示卡扣1在处于安装状态时的示意图，图5为多个卡扣与第一固定件(例如，底盘2)固定连接的立体图。如图4和图5所示，所述卡钩11和卡钩12分别位于所述卡孔21和卡孔22附近，此时所述弹性跳板14由于限位柱13抵靠底盘2而处于弯曲形变状态，从而在弹性跳板14的回弹方向上产生弹性作用力。随着在所述第一方向(即，安装方向)上移动所述卡扣1，当所述限位柱13移动到所述限位孔23的正上方时，所述卡扣1所在的位置为预定位置。这时，所 述限位柱13在所述弹性跳板14的弹性作用力的作用下落入所述限位孔23内，从而固定所述卡扣1的位置。同时，所述卡钩11与所述卡孔21卡合，所述卡钩12与所述卡孔22卡合，从而使所述卡扣1与所述底盘2固定连接。上述安装过程没有使用任何的专业工具，也不需要在所述底盘与卡扣之间拧上多颗螺丝，因此整个工作过程可以更加方便快捷，从而降低了人力成本和时间成本，提高了工作效率。
下面描述所述卡扣1的拆卸过程。首先，可以通过任何方式使所述限位柱13与所述限位孔23分开。例如，在所述限位柱13的相反侧用手指或其他任何适当工具将弹性跳板14撬起，或者在所述限位柱13一侧用任何适当工具下压限位柱13，使得所述限位柱13脱离所述限位孔23。然后，在与所述第一方向相反的第二方向(即，拆卸方向)上移动所述卡扣1。这样，所述卡钩11与所述卡孔21不再卡合，所述卡钩12与所述卡孔22不再卡合。最后，卡扣1可以从所述底盘2上卸下。上述拆卸过程没有使用任何的专业工具，也不需要在所述底盘与卡扣之间卸下多颗螺丝，因此整个工作过程可以更加方便快捷，从而降低了人力成本和时间成本，提高了工作效率。
优选的是，所述限位柱13与所述弹性跳板14是一体成型的。更优选的是，整个所述卡扣1是一体成型的。一体成型的结构使得所述卡扣更加简单，安装和拆卸也更加方便快捷。
根据本实施例提供的卡扣包括限位柱、弹性部件和至少一个卡钩。所述弹性部件设置在所述限位柱的底部。第一固定件的与所述卡钩相对应的位置设置有卡孔。所述第一固定件的与所述限位柱相对应的位置设置有限位孔。当所述卡扣移动至预定位置时，所述限位柱落入所述限位孔内，同时所述卡钩与所述卡孔卡合，从而使所述卡扣与所述第一固定件固定连接。所述卡扣的结构简单，没有使用螺丝，而且安装和拆卸无需专业工具，更加方便快捷，从而可以降低人力成本和时间成本。
第二实施例
图6为根据本实用新型的第二实施例提供的卡扣组件的局部剖面 图，图7为第二固定件的立体图，图8为第二固定件的主视图。如图6-8所示，所述卡扣组件包括第一固定件2、第二固定件3以及多个根据第一实施例提供的卡扣1。卡扣1的结构以及卡扣1与第一固定件2的安装和拆卸的详细描述可以参照上述第一实施例的内容，此处不再赘述。如图6-8所示，所述第二固定件3的边缘设置有向内弯曲的并与所述卡扣1对应的凸缘31。所述凸缘31可以与所述卡扣1相互配合以使所述第一固定件与所述第二固定件固定连接。
在本实施例中，所述卡扣组件为灯具，所述第二固定件为灯罩3，所述第一固定件为底盘2。在实际应用中，所述卡扣组件也可为显示装置，所述第一固定件为显示器主体，所述第二固定件为外壳罩。当然，其它任何具有本实用新型结构的装置都将落入本实用新型的保护范围。
优选的是，所述卡扣1的远离所述第一固定件的一侧设置有唇缘。所述唇缘与所述第二固定件的凸缘卡合以使所述第一固定件与所述第二固定件固定连接。参见图6，在本实施例中，所述卡扣1的远离所述底盘2的一侧设置有唇缘15，所述唇缘15与所述灯罩3的凸缘31卡合以使所述底盘2与所述灯罩3固定连接。在安装时，将所述灯罩3放置在所述底盘2的上方，使得所述卡扣1与所述凸缘31错开。然后转动所述灯罩3以使所述唇缘15与所述凸缘31卡合以使所述底盘2与所述灯罩3固定连接。
在本实施例中，所述卡扣1和凸缘31的数量分别为3个。在实际应用中，所述卡扣1和凸缘31的数量可以为3至6个。当然，所述卡扣1和凸缘31的数量也可以根据需要增加。优选的是，所述卡扣1与所述唇缘15是一体成型的，所述灯罩3与所述凸缘31是一体成型的。一体成型的结构使得所述灯具更加简单，安装和拆卸也更加方便快捷。
在根据本实施例提供的卡扣组件中，所述卡扣包括限位柱、弹性部件和至少一个卡钩。所述弹性部件设置在所述限位柱的底部。第一固定件的与所述卡钩相对应的位置设置有卡孔。所述第一固定件的与所述限位柱相对应的位置设置有限位孔。当所述卡扣移动至预定位置时，所述限位柱落入所述限位孔内，同时所述卡钩与所述卡孔卡合， 以使所述卡扣与所述第一固定件固定连接。所述卡扣的结构简单，没有使用螺丝，而且安装和拆卸无需专业工具。这样，在更换卡扣本身或者第一固定件和第二固定件时更加方便，增强了适用性。另外，由于更换方便快捷，降低了人力成本和时间成本。
可以理解的是，以上实施方式仅仅是为了说明本实用新型的原理而采用的示例性实施方式，然而本实用新型并不局限于此。对于本领域内的普通技术人员而言，在不脱离本实用新型的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本实用新型的保护范围。
