[0002] Elevators play an extremely important role in the work and life of modern society and bring great convenience to people. Therefore, the safe use of elevators is very important. When the traditional elevator door lock is opened, it is usually operated by a driving mechanism. When the bolt is pulled into the elevator door lock, it will collide when the bolt is pulled back, making a huge noise of metal collision, and when it is closed, the drive mechanism will be powered off, and the bolt will pop out directly under the action of the reset part. When the reset part is ejected, it will make a sound of collision, and when the latch is ejected, it will also make a loud noise of metal collision
