The invention relates to a travel switch for an elevator. The travel switch comprises a placement frame, a sliding groove column and a buckle column. A protective frame is connected to the middle of the interior of the placement frame, and the sliding groove column is arranged in the middle of the protective frame. Limiting frames are arranged on the two sides of the sliding groove column, and positioning bolts are connected into the limiting frames. The buckle column is arranged in the middle of the top end of the placement frame, and vertical bolt columns are arranged on the two sides of thebuckle column. Clamping bolts are arranged on the upper side and the lower side of the protective frame. A connecting column is arranged in the middle of the bottom end of the placement frame. The beneficial effects of the travel switch are that: the bolt columns with bolt guide holes are effectively buckled between packaging plates, the packaging plates can be packaged between clamping frames, agap sealing effect on the left side of the placement frame can be achieved, the packaging plates can be buckled between equipment gaps of the elevator travel switch in a threaded mode, dust is prevented from entering the elevator travel switch, the use effect of the elevator travel switch is improved, and failure of the elevator travel switch is avoided.
本发明涉及一种电梯用行程开关,包括安置架、滑槽柱和卡扣柱,所述安置架的内部中部连接有防护架,且防护架的中部设置有滑槽柱,所述滑槽柱的两侧安置有限位架,且限位架的内部连接有定位栓,所述安置架的顶端中部安置有卡扣柱,且卡扣柱的两侧设置有竖栓柱,所述防护架的上下两侧安装有夹持栓,所述安置架的底端中部设置有连接柱。本发明的有益效果是:有效的将带有导栓孔的栓柱卡扣在封装板之间,能够将封装板封装在卡合架之间,对安置架左侧能够达到缝隙封闭的效果,使得封装板螺纹卡扣在电梯行程开关的设备缝隙之间,预防灰尘进入电梯行程开关的内部,提高电梯行程开关的使用效果,避免发生电梯行程开关故障。
