Elevator door vane

Abstract

The invention provides an elevator door vane which comprises a bottom plate (1), a left vane arm (2), a right vane arm (3), an upper connecting rod (4) and a lower connecting rod (5). The two ends of the upper connecting rod (4) are movably connected with the left vane arm (2) and the right vane arm (3) respectively, and the two ends of the lower connecting rod (5) are movably connected with the left vane arm (2) and the right vane arm (3) respectively. The elevator door vane further comprises a lock hook assembly (12), a positioning plate (13) and a swing arm (14). The lock hook assembly (12) comprises a lock hook (121), a contact (122) and an unlocking connecting part (123), and the lock hook (121), the positioning plate (13) and the swing arm (14) are fixed in a riveted mode and movably connected to the bottom plate (1) through a third connecting shaft (63). The elevator door vane has the advantages that the lock hook assembly, the positioning plate and the swing arm are fixed and then movably installed on the bottom plate so that synchronization of unlocking of the lock hook and the disconnection of the switch contact on the swing arm can be achieved, and the smoothness and the safety of door opening and closing when an elevator is at a flat bed are improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an elevator door knife. Background technique [0002] With the rapid development of science and technology and the heightening of building floors, elevators are used more and more frequently in daily life. As a means of transportation for going up and down stairs, it is closely related to the safety of people taking elevators. requirements are becoming more and more stringent. As an important part of controlling the switch of the elevator landing door, the elevator door knife plays an important role in the daily work of the elevator. [0003] Commonly used door knives include two types: synchronous door knives and asynchronous door knives. The synchronous door knives first realize the action of clamping the floor door linkage door ball, and then the car door and the landing door are linked together; the asynchronous door knives are It moves with the car door at the same time. Before the ...

Problems solved by technology

However, what this patent adopts is the combination of the switch trigger and the lock hook. The rotation radius of the switch trigger and the lock hook is very different, and it is impossible to realize the simultaneous disconnection of the switch trigger and the unlocking of the lock hook.
