Description

technical field [0001] The invention relates to the field of elevators, in particular to a door lock linkage device for a sundries elevator landing door. Background technique [0002] When the existing elevator runs up and down, in the leveling state, the fixed bow on the car (the length of the bow surface is about 150mm) knocks the billiard ball (rubber) connected to the door lock of the landing door to unlock. the goal of. Only when the fixed bumper knocks open the billiard ball connected to the landing door lock, the user can open the landing door to get the goods in the elevator. Generally, this type of door lock adopts a single hook method, or a double hook method to lock the hall door through the action of a compression spring. This method often has great security risks. Once the compression spring fails, it cannot be locked. If the landing door is not locked and the elevator starts, the user can open the non-leveling landing door. This is a taboo in the elevato...

This method often has great security risks

Once the pressure spring fails, it cannot be locked. If the landing door is not locked and the elevator starts, the user can open the non-leveling landing door. This is a taboo in the elevator industry and is very unsafe.

Moreover, there is no electrical interlock device on the door lock, so it is impossible to judge whether the door lock is hooked. If it is not hooked, the user can open it in the non-leveling area, which is also very dangerous; so this is an unqualified door lock device.
