The invention relates to the technical field of elevators, and discloses an elevator door knife cam and movable light curtain linkage device. The device comprises a first car door, a second car door and a fixing plate, wherein the first car door is fixedly connected with the second car door, the fixing plate is located at the top of the first car door and the top of the second car door, and the surface of the fixing plate is fixedly connected with a movable door knife cam. According to the elevator door knife cam and movable light curtain linkage device, by means of a first electromagnetic switch, an upper connecting piece and electromagnets, when the upper connecting piece makes contact with a lower connecting piece, a second electromagnetic switch and the first electromagnetic switch are powered on, so that the electromagnets have magnetic force, the electromagnets repel each other to push an elevator light curtain into the inside of the first car door and the second car door, springs are arranged and reset after being extruded to push the elevator light curtain out of the inside of the first car door and the second car door, then the elevator light curtain can conveniently detect passengers or obstacles, and the elevator light curtain is stretched out and drawn back when an elevator is opened and closed.
本发明涉及电梯技术领域,且公开了一种电梯门刀及可动式光幕联动装置,包括第一轿门、第二轿门和固定板,所述第一轿门和第二轿门固定连接,所述固定板位于第一轿门和第二轿门的顶部,所述固定板的表面固定连接有移动门刀。该电梯门刀及可动式光幕联动装置,通过第一电磁开关、上连接件和电磁铁,上连接件和下连接件接触时第二电磁开关和第一电磁开关进行通电,从而使电磁铁具有磁力,电磁铁之间相互排斥将电梯光幕推进第一轿门和第二轿门的内部,通过设置弹簧,弹簧受到挤压后复位将电梯光幕从第一轿门和第二轿门的内部推出,从而便于电梯光幕对乘客或阻挡物进行检测,从而实现电梯在开关时将电梯光幕进行伸缩。
