Synchronous door cam device integrated with car door lock

Abstract

The invention discloses a synchronous door cam integrated with a car door lock. The synchronous door cam provides a door machine bottom plate, and a door hanging plate which horizontally slides along the door machine bottom plate and is used for hanging a car door; a door cam bottom plate is fixedly mounted on the door hanging plate; a hook seat is fixed on the door machine bottom plate; a movable blade oscillating mechanism and an unlocking blade assembly are mounted on the door cam bottom plate and positioned at the left inner side and the right inner side or the left outer side or the right outer side of a landing door roller and can be used for clamping or propping the landing door lock roller; a transmission assembly is connected to the movable blade oscillating mechanism; one end of the transmission assembly is hinged on a door machine transmission belt which drives the door hanging plate to move, and while the other end of the transmission assembly is hinged to the movable blade oscillating mechanism; the movable blade oscillating mechanism links with the unlocking blade assembly, wherein the unlocking blade assembly is in match with a lock hook hinged to the door cam bottom plate and can be used for triggering the lock hook to hook or separate from a hook seat. According to the synchronous door cam device, the car door can be opened or closed simply by the landing door lock roller; a car door locking mechanism is integrated to the synchronous door cam, so that the structure of the door cam is simplified, and the difficulty at mounting and debugging can be reduced.

Description

technical field [0001] The invention relates to the field of elevator products, in particular to a synchronous door knife device with a car door locking mechanism. Background technique [0002] The popularization of the use of elevators has greatly facilitated people's lives at present, and at the same time, the safety performance of elevators is also increasingly concerned. [0003] The national standard GB7588-2003 "Safety Code for Elevator Manufacturing and Installation" stipulates in 11.2.1: the horizontal distance between the inner surface of the elevator shaft and the edge of the nearest door of the car sill, car door frame or sliding door should not be greater than 0.15m, It also stipulates that: if the car is equipped with mechanically locked doors and can only be opened in the unlocking area of ​​​​the landing door, except for the cases mentioned in 7.7.2.2, the operation of the lift shall automatically depend on the locking of the car door. And the locking of the ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the door knife of the elevator and the car door lock great majority are set up separately, as the Chinese patent of CN101117870 of Chinese Patent Publication No., the title is called the invention patent application of the elevator car door lock, and it needs to carry out the door when installing. The debugging of the knife and the car door lock is not only inefficient, but also leads to an increase in the failure rate

[0005] Also having a kind of prior art in addition is: the secondary roller of landing door is set on the landing door lock, and the car door lock is opened or closed by the secondary roller, as disclosed in a kind of elevator car door lock device disclosed by Chinese Patent Publication No. CN101081677. The auxiliary gate ball rollers are coordinated and linked, the structure of the device is complex, the installation and debugging efficiency is low, and the cost is high
