图6与图7是本发明卡扣装置较佳实施方式的剖面图,其分别表示两种不同的使用状态。
具体实施方式
请参阅图1及图2,本发明卡扣装置应用于笔记本电脑上,是将一盖体10锁固于一基座20,该卡扣装置包括装设于该基座20内的一按动件30、一卡扣件40、一固定件50、一卡抵件60、一弹性元件70及一抵顶件80。其中该弹性元件70在本实施方式中为一弹簧。
该基座20包括一底板22及盖设于该底板22的盖板24。该底板22的边缘向上凸伸形成一凸楞221。该凸楞221的中部开设一收容槽224。一凸柱222凸设于该底板22上邻近该收容槽224处。该凸柱222上开设一固定孔223。该底板22远离该收容槽224处突设有一长形的定位柱224及一固定柱225,该固定柱225沿轴线开设一固定孔226。该盖板24开设一通孔242。
该按动件30包括一柱状部32及设置于该柱状部32一侧的驱动部34。该驱动部34呈直角梯形,其包括一倾斜的抵推面342。
该卡扣件40呈长形,其包括一推抵端41及一卡扣端。该卡扣件40于靠近该抵推端41处开设一长形的第一限位槽43。该卡扣件40于靠近该卡扣端处开设一长形的第二限位槽45。该卡扣件40于其第二限位槽45与端缘之间开设一方形通孔46以使该端缘处形成一卡掣部473。
请参阅图3,该盖体10的一侧设置一柱状的卡钩12,该卡钩12的末端设置一钩扣部,该钩扣部包括一形成于末端的呈圆台状的导引部122及一开设于该导引部122附近的卡槽124。
请一并参阅图4与图5,该固定件50包括一大致呈长方形的基板51。该基板51的一侧中部突设一圆柱体52,该圆柱体52周围设置若干加强肋。该圆柱体52沿其轴线方向开设一台阶孔,该台阶孔包括一开设于该圆柱体52顶部的直径较小的通孔522及一直径较大的并且贯通该固定件50的容置孔524。该圆柱体52于其上部开设一开槽526,该开槽526连通于该容置孔524。该固定件50于该圆柱体52附近突设一凸柱53,该凸柱53沿轴向开设一固定孔532。该固定件50于其另一侧面突设两截面呈L形的卡固部56,两卡固部56对称设置于该容置孔524两侧。该基板51上还开设一固定孔58及一长形的定位孔59。
该卡抵件60包括一半圆形的底壁61及一沿该底壁61的弧形边缘向一侧延伸形成的U形的侧壁62。该侧壁62的末端对称设置两凸耳64,每一凸耳64沿其向着该底壁61的一面上设置一凸点642。
该抵顶件80为一台阶状的圆柱体,其包括一大端82及一小端84。
请一并参阅图6,组装时,将该抵顶件80及该弹性元件70先后置入该固定件50的台阶孔内。将该卡抵件60附着于该固定件50的有卡固部56的一侧,使该卡抵件60的两凸耳64分别卡入该固定件50的两卡固部56内,凸点642起辅助卡紧的作用。该弹性元件70的一端卡抵于该抵顶件80的大端82,该弹性元件70的另一端卡抵于该卡抵件60的底壁61。将该固定件50置于该底板22的固定柱225及定位柱224上,使该底板22的定位柱224卡入该固定件50的定位孔59内。利用一螺丝(图未示)穿过该固定件50的固定孔58锁入该底板22的固定柱225的固定孔226内将该固定件50固定于该底板22。其中该固定柱225的高度应该使该固定件50与该底板22之间的距离足以容纳该卡抵件60。
利用两螺丝90分别穿过该卡扣件40的第一限位槽43及第二限位槽45并分别锁入该底板22的凸柱222上的固定孔223及该固定件50的凸柱53上的固定孔532将该卡扣件40滑动装设于该底板22上。该按动件30容置于该底板22的收容槽224内。该按动件30的一抵推面342抵顶于该卡扣件40的推抵端41。
然后将该盖板24与该底板22盖合,使卡扣件40的通孔46对应于该盖板24的通孔242。在该弹性元件70的弹力作用下,该抵顶件80的小端84突出于该圆柱体52的顶部并穿入该盖板24的通孔242内将该通孔242填平,使该盖板24的表面平整。
请一并参阅图7,将该盖体10枢转装设于该基座20,旋转该盖体10,该卡钩12的导引部122将该抵顶件80压下并穿过该卡扣件40的通孔46。该卡扣件40可利用一弹簧(图未示)进行复位,在该弹簧(图未示)的回复力作用下,该卡扣件40的卡掣部473穿过该圆柱体52的开槽526卡入该卡钩12的卡槽124内,从而使该卡钩12钩扣于该卡扣件40,此时该盖体10锁固于该基座20。
当需要打开该盖体10时,向内按动该按动件30,该按动件30的驱动部34推抵该卡扣件40的推抵端41,使该卡扣件40向远离该按动件30的方向移动,直到该卡扣件40的卡掣部473从该卡钩12的卡槽124内完全退出,从而可将该盖体10相对该基座20打开。打开后,在该弹性元件70的弹力作用下,该抵顶件80的小端84突出于该圆柱体52的顶部并穿入该盖板24的通孔242内将该通孔242填平,使该盖板24的表面平整。
显而易见地,作为本发明卡扣装置的第二较佳实施方式,该弹性元件70的另一端可直接卡抵于该底板22上,进而可以省掉该卡抵件60。
