Synchronous door knife integrated with car door lock and synchronous door knife system

Abstract

The invention discloses a synchronous door knife integrated with a car door lock and a synchronous door knife system. The synchronous door knife integrated with the car door lock comprises a door knife bottom plate, and a blade assembly and a latch hook assembly which are linked are installed on one face of the door knife bottom plate. The synchronous door knife integrated with the car door lock is characterized in that a swing arm is installed on the other face of the door knife bottom plate; a door machine force application shaft is arranged at the free end of the swing arm; a swing arm reset compression spring is arranged between the door knife bottom plate and the swing arm; a linkage pin shaft penetrating the door knife bottom plate is arranged between the swing arm and the door knife assembly; and a locking assembly matched with the swing arm to limit swing is further installed on the door knife bottom plate. According to the synchronous door knife integrated with the car door lock and the door knife system, force transmission is simple and reliable, opening and closing are achieved through a safety loop, the risk of dust accumulation is avoided, the integration level is high, debugging is convenient, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an integrated car door lock synchronous door knife and a synchronous door knife system. Background technique [0002] With the gradual improvement of elevator safety performance requirements, the new GB7588 standard requires that the motor door opening mechanism needs such a function: it can lock the car door in the non-leveling section of the elevator, and allow the car door to be locked in the leveling section of the elevator under any circumstances. Can be unlocked to allow passengers to escape. [0003] For this, there are basically two solutions in the market; [0004] The first type is an independent car door lock, which is not directly related to the door knife and landing door kick that execute the door opening; [0005] The second type is the car door lock integrated in the door knife, relying on the clamping of the landing gate kick to judge whether the floor is lev...

AI Technical Summary

Problems solved by technology

The transmission process of multiple connecting rods is complicated, which can easily cause the risk of being stuck, and the lock hook is pressed into the socket from top to bottom, which will still cause the risk of dust accumulation, and excessive dust accumulation will cause the elevator to stop

In this patent document, there are two parts that cooperate with the action of the door knife: the auxiliary lock placed on the auxiliary hanging plate and the contact mounting plate on the door head of the door operator. Many matching parts will cause difficulty in site adjustment.
