Elevator landing door combination mounting anti-off device

Abstract

Provided is an elevator landing door combination mounting anti-off device. The elevator landing door combination mounting anti-off device solves the problems of breakdown and hidden danger caused by unreasonable design in an existing landing door anti-off scheme. The elevator landing door combination mounting anti-off device comprises a sill and two door leaves which are assembled on the sill. The elevator landing door combination mounting anti-off device is characterized in that a guiding sliding groove of the sill adopts a U-shaped opening type structure, a guiding sliding block and a guiding anti-off sliding block are fixed at the bottom of lower end sockets of the door leaves, a left anti-off straight hook and a right anti-off straight hook are arranged on the portions of door pillars corresponding to the lower portions of the two door leaves, a locking screw is utilized by the middle portion of the guiding sliding groove of the sill to fix an anti-off stop dog, when a landing door is in a locking position, an anti-off hook of the anti-off sliding block is inserted into an anti-off cavity of the anti-off stop dog, and the left anti-off straight hook and the right anti-off straight hook respectively hook a shift stopping part which prevents the door leaves from falling off. The elevator landing door combination mounting anti-off device has the advantages of being simple in structure, rational in design, convenient to use, safe and reliable, capable of prominently improving an anti-off function of the elevator landing door, effectively avoiding the landing door leaves from falling off the guiding groove of the sill, and radically eliminating potential safety hazard that opening or closing a door is stuck or passengers drop from the elevator.

Description

technical field [0001] The invention relates to an improved elevator landing door safety protection device, in particular to an elevator landing door combination hanger used to prevent the door leaf from being impacted by abnormal external force and the sliding block at the lower part of the door leaf detaching from the sill guide groove when the landing door is in a locked state. Connect the anti-loosening device. Background technique [0002] Elevators are an indispensable and important part of modern buildings. They have become the best choice for people to walk through buildings because of their convenience and speed. People pay attention to it, especially when the landing door is hit by an abnormal external force and the door leaf is separated, which causes the ladder falling accident to attract the most attention. In order to avoid the above-mentioned falling accidents, according to literature reports, many manufacturers in the industry at home and abroad try to adopt...
