Problems solved by technology

When this structure is implemented, the unlocking action of landing door opening can only rely on the elastic force of the elastic element. Since the elastic element will work tired, the elastic force will decrease after working for a long time. If the elastic force cannot make the movable door hook tilt up, Then the lock cannot be unlocked, and the car door cannot be opened at this time, which will pose a safety hazard
Moreover, in this structure, when the landing door is closed, the elastic force of the first compression spring acts horizontally on the push rod of the landing door hanging plate, and this elastic force will form a large resistance to the automatic closing of the landing door.
Therefore, the structure is not safe for practical application

Abstract

The invention discloses a gate lock device of an elevator car. The gate lock device comprises an elevator-car-side gate lock device and a landing-side unlocking device, wherein the elevator-car-side gate lock device is provided with an unlocking roller, the landing-side unlocking device is provided with a striking plate, when a carriage and a landing are opened and interlinked, the unlocking roller of the elevator-car-side gate lock device is initiatively pressed by the striking plate of the landing-side unlocking device under the effect of gravity, so that the elevator-car-side gate lock device is opened. The gate lock device of the elevator car, provided by the invention, has the advantages of simple structure, capability of greatly saving an inner mounting space of a beam of an elevator car machine, convenience for installation, and stable and reliable unlocking action.

Description

technical field [0001] The invention relates to an elevator accessory, in particular to an elevator car door lock device. Background technique [0002] When the horizontal distance between the inner surface of the elevator shaft and the car sill, the car door frame or the edge of the nearest door of the sliding door is large, in the process of the elevator running up and down, in order to prevent passengers from falling into the shaft after opening the door in the non-unlocking area, The car is required to be equipped with a mechanically locked car door and the car door can only be opened in the unlocking area of ​​the landing door. The operation of the elevator should automatically depend on the locking of the car door, and the locking of the car door must be detected and confirmed by an electrical safety device that meets certain requirements. [0003] At present, the elevator car door lock device has the following structures: [0004] 1. The rotating hook of the elevato...
