The top of the elevator door 1 is fixedly connected to the connecting block 2, the upper side of the connecting block 2 is fixedly connected to the first sliding plate 3, one side of the first sliding plate 3 is fixedly connected to the metal column 5, the first sliding plate 3 slides on a slide 6, one side of the slide 6 is fixedly connected to the wall 7, one side of the wall 7 is fixedly connected to the top plate 4, the lower end of the top plate 4 is fixedly connected to the detection module 9, the lower side of the detection module 9 A magnetic interface 11 is provided inside, and a door lock 10 is provided below the detection module 9. The door lock 10 includes a joystick 1001, a rotating shaft 1002, a telescopic joint 1003 and an iron hook 1004. The top of the joystick 1001 is fixedly connected to the telescopic joint 1003, the left bottom end of the joystick 1001 is fixedly connected to the iron hook 1004, one side of the joystick 1001 is rotatably connected to the rotating shaft 1002, and the end of the rotating shaft 1002 away from the joystick 1001 is fixedly connected to the second sliding plate 8.

[0025] There are two elevator doors 1 so that the elevator can work normally; there are two connecting blocks 2 so that the elevator door 1 drives the first sliding plate 3 to move on the slide 6; there are two magnetic interfaces 11 so that they can attract the telescopic joint 1003; the first sliding plate 3 and the second sliding plate 8 have the same shape and size and can both slide freely on the slide 6.

[0026] Working process: The electricity required by the utility model is provided by an external power supply. When the elevator door lock device needs to be used, if the elevator door 1 is closed, the connecting block 2 at the top of the elevator door 1 will drive the first sliding plate 3 and the second sliding plate 8 to slide in the slide 6 on the wall 7, and the second sliding plate 8 drives the door lock 10 to move. The second sliding plate 8 and the door lock 10 are fixedly connected by the rotating shaft 1002. The door lock 10 includes a joystick 1001, a rotating shaft 1002, a telescopic joint 1003 and an iron hook 1004. At this time, the telescopic joint 1003 will touch the top The detection module 9 at the bottom of the plate 4 is provided with a magnetic interface 11 at the bottom of the detection module 9.
