Description

推拉开关
推拉开关属于建筑门窗上的部件。
目前,防撬门上的门窗开口处,所装小门由于人站在室内操纵开启或关闭,有时会关闭不严,有缝隙。
本实用新型的目的是提出一种为防撬门配套使用的推拉开关,使安装在防撬门上的小门推拉方便牢固可靠。
本实用新型是这样实现的,推拉开关拉杆的一端固定钩板,拉杆中部是凸台结构上面有卡槽,在拉杆上有弹簧,与弹簧配套的滑套外装有固定座和卡板组成的锁紧装置。
根据附图对本实用新型做进一步说明:
图1推拉开关关闭状态结构示意图;
图2,图1的A-A锁紧装置视图;
图3锁紧装置开启视图;
图4推拉开关开启状态结构示意图。
图中:拉杆10的一端紧固有钩板1,拉杆中部是凸台结构,外部有滑套3,滑套的移动与钩板夹紧小门板2拉杆10中间有卡槽,且上面套有弹簧4,滑套3上有凸台,凸台的右端安装有由固定座5和卡板8拉簧12组成的锁紧装置,锁紧装置往右移由滑套3上的凸台和固定座5夹紧小门框6,固定座与卡板间用联接轴7连接并用小螺母9拧紧,拉杆的另一端是手柄11。
下面对推拉开关的工作情况做说明如下:
推拉开关关闭说明:
先转动手柄90°,拉杆10,钩板,使这3个件变位为横向,再用力拉动手柄11,带动拉杆10,与钩板,迫使小门板2向内靠进一定位置时,两卡板8在拉簧12的拉力作用迫使两个卡板8,正好与拉杆凹槽向交卡住,完成关闭状态,见图1-图2所示。
推拉开关开启说明:
先转动手柄11成90°,拉杆10,钩板1经过转动后使这3个件变位当成竖向,两个卡板8同时张开口,在弹簧12的弹力推动拉杆10向外伸出所需的长度,小门板12同时脱离钩板1。完成开启状态。见图3-图4所示。
