The invention belongs to the field of elevators, solves the problem of how to provide a hand-pulling type ejector rod assembly for testing a speed limiter, and relates to a self-inspection type elevator speed limiter hand-pulling type electrical switch ejector rod assembly which comprises an ejector rod used for pushing an electrical switch contact forwards to turn off an electrical switch, and further comprises a support, a push rod, a push rod, a push rod, a push rod and a push rod, a penetrating hole I is formed in the support, and the ejector rod is arranged in the penetrating hole I in a penetrating mode and can slide back and forth relative to the support. The pulling mechanism comprises a movable plate and a pull rod used for pulling the movable plate; the baffle is connected to the ejector rod and located on the rear side of the movable plate. The ejector rod is sleeved with the spring, the spring is located between the movable plate and the baffle, and the length of the spring is smaller than the maximum distance between the movable plate and the baffle. The beneficial effects are that the test can be started by hand pulling, and the arrangement of the hand-pulling type push rod assembly does not affect the normal operation of the elevator.
本发明属于电梯领域,解决了如何提供一种手拉式的顶杆组件来进行限速器测试的问题,涉及一种自检型电梯限速器手拉式电气开关顶杆组件,包括用于向前推动电气开关触点以关闭电气开关的顶杆,还包括:支架,所述支架中设置有穿孔Ⅰ,所述顶杆穿设在所述穿孔Ⅰ中并能够相对于所述支架前后滑移;拉动机构,所述拉动机构包括活动板和用于拉动所述活动板的拉杆;挡板,所述挡板连接在所述顶杆上且位于所述活动板后侧;弹簧,所述弹簧套设在所述顶杆上,所述弹簧位于所述活动板和所述挡板之间,所述弹簧的长度小于所述活动板与所述挡板之间的最大距离。有益效果是能够实现手拉来启动测试,且手拉式顶杆组件的设置不影响电梯正常运行。
