Elevator door vane device with locking mechanism

Abstract

The invention relates to the technical field of elevator door vanes, and discloses an elevator door vane device with a locking mechanism. The elevator door vane device comprises a bottom plate, a left door vane is arranged on the front side of the bottom plate, a right door vane is arranged on the right side of the left door vane, a rotating plate is arranged on the rear sides of the left door vane and the right door vane, the rotating plate is positioned on the front side of the bottom plate, and a door vane locking mechanism is arranged on the left door vane and the right door vane. The door vane locking mechanism comprises a rotary shaft. According to the elevator door vane device with the locking mechanism, through the arrangement of the rotating shaft, the left door vane and the right door vane can penetrate through the rotating shaft, the left door vane and the right door vane are effectively connected in a screwed mode through matched external threads, meanwhile, the rotating plate can be conveniently connected in a penetrating mode, and through the arranged ball bearing, the rotating shaft and the rotating plate can be effectively and movably connected, meanwhile, the rotating plate can conveniently drive the left door vane and the right door vane to move close to each other and separate from each other, the good smooth rotating effect is achieved, and through the arranged nut, the effective limiting and locking effect on the upper end of the rotating shaft is achieved.

Description

technical field [0001] The invention relates to the technical field of elevator door blades, in particular to an elevator door blade device with a locking mechanism. Background technique [0002] As a vertical means of transportation, elevators are used more and more in buildings such as high-rise residences, business hotels, office buildings, and shopping malls. The frequency of elevator use varies depending on the occasion. Elevators are widely used, and accidents caused by the equipment itself or improper human operation methods also occur from time to time, especially the problem of the door system, which accounts for about 80% of elevator accidents. [0003] In the use of the elevator door knife in the prior art, bolts are usually used to fix the elevator door knife, but because the elevator door knife often needs to rotate and the elevator often vibrates during operation, the elevator door knife is easy to Loose, resulting in inaccurate contact with the gate ball, so ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an elevator door knife device with a locking mechanism, which has the advantages of effective locking and auxiliary limit, and solves the problem that the door knife in the traditional technology is easy to loosen and affects the overall use
