A wire threading hole 24 is opened on the back of the outer housing 2, and the wire threading component 6 is arranged in the wire threading hole 24.

[0025] Preferably, the adjusting assembly 5 includes an inner hinge seat 51, an outer hinge seat 52 and a second spring 56. An inner push rod 53 and an outer push rod 54 are respectively rotatably connected to the inner hinge seat 51 and the outer hinge seat 52. A first spring 55 is provided inside the inner push rod 53 and the outer push rod 54. The outer end of the second spring 56 is connected to a movable shaft 57 and a push-pull block 58 is fixed to the outer end of the movable shaft 57. The inner hinge seat 51 is fixed to the inner wall of the outer housing 2, and the outer hinge seat 52 is fixed to the back of the identifier 3. The inner push rod 53 and the outer push rod 54 are rotatably connected to each other. Two sets of first springs 55 are provided. The two ends of the first spring 55 are respectively connected to the outer housing 2 and the identifier 3. The second spring 56 and the movable shaft 57 are located inside the upper and lower ends of the identifier 3. A limiting hole 23 is formed in the inner wall of the outer housing 2. The outer end of the movable shaft 57 penetrates through the identifier 3 and is inserted into the limiting hole 23;

[0026] Through the cooperation of the push-pull block 58 and the second spring 56, the movable shaft 57 can be driven to perform elastic telescopic movement. Through the cooperation of the movable shaft 57 and the limiting hole 23, the installation position of the identifier 3 can be limited. Through the cooperation of the inner push rod 53, the outer push rod 54 and the first spring 55, the identifier 3 can be elastically pushed and controlled back and forth, which is convenient for popping out for maintenance or retracting and embedding for installation.

[0027] Preferably, the wire threading assembly 6 includes a rear cover plate 61 and a front cover plate 62. External threads 63 and internal threads 64 are respectively provided on the inner sides of the rear cover plate 61 and the front cover plate 62. Rubber rings 65 are provided on the inner sides of the rear cover plate 61 and the front cover plate 62. The rear cover plate 61 and the front cover plate 62 are inserted on both sides of the wire threading hole 24, and the external threads 63 and the internal threads 64 are screwed and fixed;

[0028] Through the cooperation of the external threads 63 and the internal threads 64, it is convenient to connect and install the rear cover plate 61 and the front cover plate 62 and fix them in the wire threading hole 24. Through the rubber ring 65, it is convenient to protect the internal wire threading and avoid problems such as wear and breakage of the wire harness.

[0029] The working principle and working process of the present utility model: When in use, the outer housing 2 can be installed on the inner wall of the elevator through the side blocks 21 and the fixing bolts 22. Then, the internal wire harness of the identifier 3 is connected to the outside. The wire harness is threaded through the rubber ring 65. Through the external threads 63 and the internal threads 64, the two cover plates can be tightened or loosened and their positions in the wire threading hole 24 can be adjusted. After adjustment, they can be tightened and fixed. At this time, the two push-pull blocks 58 can be squeezed inward, so that the movable shaft 57 contracts into the identifier 3. Then, the identifier 3 is pushed into the inner part of the outer housing 2, so that the inner push rod 53 and the outer push rod 54 rotate towards each other, and the first spring 55 is compressed. When the identifier 3 completely enters the outer housing 2, the push-pull block 58 is released, and the second spring 56 pushes the movable shaft 57 to be elastically inserted into the limiting hole 23. At this time, the installation of the identifier 3 is completed. When disassembling, the reverse operation can be performed, which can realize the quick disassembly and assembly and embedded protection of the identifier 3.
