The protrusion 301 is slidably connected to the driving groove 501 according to the radius of the stabilizing plate 4. The side of the driving groove 501 coincides with the side of the stabilizing plate 4. The middle of the stabilizing plate 4 is fixedly connected to the output shaft of the motor 2. One end of the connecting rod 502 is fixedly connected to the middle of the driving groove 501. The other end of the connecting rod 502 is rotatably connected to the inner wall of the ladder wall 1. The diameter of the driving gear 6 is equal to the diameter of the driven gear 7. Both the driving gear 6 and the driven gear 7 are bevel gears. The driven gear 7 is fixedly connected to the bottom of the display screen 8. One end of the support rod 801 is rotatably connected to the bottom of the display screen 8. The other end of the support rod 801 is fixedly connected to the bottom of the inner cavity of the ladder wall 1. The display screen 8 and the display groove 101 are at the same height.

[0023] Specifically, a display slot 101 is provided on the ladder wall 1, and the display screen 8 and the display slot 101 are located at the same height, so that the elevator user can clearly observe the information displayed on the display screen 8, a motor 2 is fixedly installed on the inner wall of the ladder wall 1, a driving rod 3 and a stabilizing plate 4 are fixedly welded on the output shaft of the motor 2, and the stabilizing plate 4 is located on the right side of the driving rod 3, a protrusion 301 is fixedly welded at the end of the driving rod 3, and the length of the driving rod 3 is greater than the radius of the stabilizing plate 4, so that the protrusion 301 is located outside the side of the stabilizing plate 4, The stabilizing plate 4 is rotatably connected to the rotating plate 5 on the side, and a driving groove 501 is provided on the rotating plate 5, so that the protrusion 301 can enter the driving groove 501 and slide when rotating, thereby driving the rotating plate 5 to rotate, and the side of the rotating plate 5 coincides with the side of the stabilizing plate 4, so that when the rotating plate 5 rotates, the side of the rotating plate 5 can fit closely with the side of the stabilizing plate 4, thereby ensuring that the rotating plate 5 does not shake when rotating, and a connecting rod 502 is fixedly welded in the middle of the side of the rotating plate 5, and the other end of the connecting rod 502 is rotatably connected to On the inner wall of the ladder wall 1, in order to provide support for the connecting rod 502 without affecting the rotation of the connecting rod 502, three driving gears 6 arranged at equal intervals are fixedly welded on the connecting rod 502, and a driven gear 7 is meshed on each driving gear 6, and the driving gear 6 and the driven gear 7 are bevel gears, so as to increase the contact area between the driving gear 6 and the driven gear 7, so that the connection is more stable, and the supporting force of the driving gear 6 can be improved. A display with three display screens 8 is fixedly welded on the upper surface of the driven gear 7, so that when the driving gear 6 drives the driven gear 7 to rotate, the driven gear 7 can drive the display to rotate, thereby realizing the switching of the display screen 8. Due to the special shape of the rotating plate 5 and the shape of the display is a triangle, the rotating plate 5 can realize the perfect switching of the display screen 8 when it rotates. A support rod 801 is rotatably connected to the bottom of the display screen 8, and the other end of the support rod 801 is fixedly connected to the bottom of the inner cavity of the ladder wall 1, so that the support rod 801 can provide support for the display screen 8 without affecting the rotation switching of the display screen 8.

[0024] The working principle and use process of the utility model are as follows: first, the display screen 8 on the same side of the three displays is turned on, and information can be transmitted to the elevator user at this time. When the display screen 8 in use fails, the motor 2 can be started to control the driving rod 3 and the stabilizing plate 4 to rotate, and the protrusion 301 will slide in the driving groove 501, thereby driving the rotating plate 5 to rotate, and the rotating plate 5 drives the connecting rod 502 to rotate, and the connecting rod 502 drives the driving gear 6 to rotate, and then the driving gear 6 can drive the driven gear 7 to rotate, and finally drive the three displays above the driven gear 7 to rotate at the same time, realizing the switching of the display screen 8, thereby hiding the failed display screen 8, and using the healthy display screen 8, avoiding the untimely and inaccurate information transmission due to only one window for transmitting information.
