Externally-supported door vane car door lock device and method

Abstract

The invention provides an externally-supported door vane car door lock device and a using method. A transition plate, a first connecting block, a second door vane arm and a second connecting block aresequentially hinged to form a first parallelogram structure, the transition plate, a first swing arm, a first door vane arm and a second swing arm are sequentially hinged to form a second parallelogram structure, and the first door vane arm is fixedly provided with an unlocking block; a lock hook assembly comprises a lock hook body and a pulling lever, the lock hook body is hinged to a door vanebottom plate, the pulling lever is fixedly connected with the lock hook body, the relative orientation between the pulling lever and the unlocking block is configured to be that after the first door vane arm swings to a preset position, the unlocking block can touch the pulling lever to rotate the lock hook body to achieve unlocking. During in-car door pushing, conversion into rotation action of adoor vane is achieved, and the unlocking operation of a car door lock is the same as the operation when a door is normally opened. Moreover, during out-hall door pushing, single tool arm motion is done, the structure of the overall car door lock is simplified, the unlocking action is reliable and stable, the production and processing cost is reduced, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of elevator accessories, in particular to an outrigger door knife car door lock device and method. Background technique [0002] After the introduction of the new national standard GB7588 No. 1 Amendment, more explicit requirements have been made on the opening of the car door, that is, in the non-leveling area, the car door cannot be opened for any reason; The car door should be able to be opened inside. [0003] In order to achieve the above functions, the existing outrigger car door lock technology relies on the driving force of the driving element to continuously output the holding force, so that the car door lock keeps the retracted state when the door is closed, and the lock hook is in the locked state at this time. When opening the door normally, the drive element drives the door knife to prop the door knife arm open, and now the door knife arm touches the floor door ball to unlock the car door lock....

AI Technical Summary

Problems solved by technology

Utilizing the continuous output of the driving element is very easy to cause continuous heating of the driving element, thereby shortening its service life

In addition, when the car accidentally loses power when the car is running, because the door knife will be opened under the action of the return spring, it is easy to hit the door ball on the floor and cause danger.

[0004] Although there are also some mechanical outrigger car door locks in the prior art, the unlocking under normal door opening, car door opening, and hall door opening depends on different linkage structures, resulting in complex and stable car door lock structures. Poor performance and high cost
