Problems solved by technology

However, most of the existing car door locks are provided with a locking device independent of the door knife mechanism at the door opener, and an unlocking device independent of the door ball is set on the landing door. When the car door is in the unlocking area of ​​the landing door When the unlocking device opens the locking device at the car door to achieve normal door opening, but if it is in the non-unlocking area, the locking device at the car door opener cannot be opened, and the car door cannot be opened.
The disadvantage of this kind of car door lock is that the structure is complicated, and the installation is time-consuming, which not only wastes the material cost but also wastes the installation man-hours of the personnel, and once the car door lock is damaged, it is more difficult to repair.

Abstract

The invention discloses a simple elevator car door lock, which comprises a door knife mechanism arranged on a door opening machine and driven by a motor driving belt, a car door lock hook, and a lock catch matched with the car door lock hook, wherein the lock catch is fixed on an upper ridge of the door opening machine, and the car door lock hook is matched with the door knife mechanism in a linkage mode; when an elevator is positioned in a hall door unlocking area, a door ball is clamped by the door knife mechanism, so that the car door lock hook is separated from the lock catch; and when the elevator is positioned in a hall door locking area, the door knife mechanism is folded, so that the car door lock hook is buckled with the lock catch, and the elevator car door can not be opened. The simple elevator car door lock has a simple structure and high reliability, and is convenient to install and maintain.

Description

technical field [0001] The invention relates to a simple elevator car door lock. Background technique [0002] The national standard GB75-88-2003 "Safety Code for Elevator Manufacturing and Installation" stipulates in 12.2.1: the horizontal distance between the inner surface of the elevator shaft and the car sill, car door frame or the nearest door edge of the sliding door should not be greater than 0.15 m. It also stipulates that if the car is equipped with mechanically locked doors which can only be opened in the unlocked area of ​​the landing doors, the operation of the lift shall automatically depend on the locking of the car doors, except in the cases mentioned in 7.7.2.2, and The locking of the car door must be confirmed by an electrical safety device that meets the requirements of 14.1.2, and the above distance is not limited. Therefore, if the distance specified in 11.2.1 exceeds 0.15m, the car door lock can meet the standard. The function of the car door lock is t...
