The invention discloses an elevator door anti-pinch device, and belongs to the field of elevator equipment, the elevator door anti-pinch device comprises a door frame, door plates and a controller, the door plates are arranged in two groups, the two groups of door plates are arranged on one side of the door frame, the lower ends of the two groups of door plates are slidably connected with sliding rails, and the sliding rails are fixedly mounted on the door frame; the upper end of the door plate is fixedly connected with an electric push rod, the electric push rod is installed on the door frame, and the electric push rod is electrically connected with the controller; detection mechanisms are arranged in the two sets of door plates and used for detecting whether foreign matter exists between the two sets of door plates or not after the two sets of door plates are closed. When the elevator door is closed, the trigger plate can clamp a foreign matter, then the trigger plate moves towards the interior of the door plate to trigger the detection mechanism and the standby detection mechanism, and therefore the elevator door is controlled to be opened, the problem that glass cannot be detected through infrared rays is solved, and meanwhile the problem that a rope chain cannot be detected through dead corners generated through infrared detection is solved.

    本发明公开了一种电梯门防夹装置,属于电梯设备领域,包括门框、门板及控制器,所述门板呈两组设置,两组所述门板设置在门框的一侧,两组所述门板的下端滑动连接有滑轨,所述滑轨固定安装在门框上,所述门板的上端固定连接有电动推杆,所述电动推杆安装在门框上,所述电动推杆与控制器电性连接;两组所述门板的内部均设置有检测机构,所述检测机构用于检测两组门板在关闭后,其两者之间是否有异物。可以实现在电梯门关闭时触发板会夹住异物,然后触发板向门板内移动触发检测机构和备测机构,从而控制电梯门打开,解决了红外线检测不到玻璃的问题,同时也解决了红外线检测出现死角检测不到绳链的问题。
