Technical Field

The invention relates to the technical field of elevators, in particular to an asynchronous door vane device.

Background

The asynchronous door knife device is mounted on the lift car and moves along with the lift car to clamp a door ball assembly on the landing door device so as to open the landing door device. Because the asynchronous door vane has the characteristic of firstly opening the door and then unlocking the door vane device, the problem that the lock hook of the asynchronous door vane device is locked with the fixed hook of the car door and cannot be opened easily occurs in the door opening process. And when the door machine is closed in place, the locking hook of the asynchronous door knife device impacts the fixed hook of the car door, so that abnormal sound and the like during closing are caused, and improvement is needed.
