When the second connecting rod 11 rotates, the slide plate 13 is driven to slide back and forth left and right through the connecting rod 12, thereby driving the cleaning brush 15 to slide left and right, and the dust on the surface of the rising display screen 3 is wiped back and forth, so that the dust on the surface of the display screen 3 is cleaned.

[0028] The active rod 5 passes through the outer shell 2 and is rotatably connected to the outer shell 2. A threaded rod 16 is fixedly connected to the top of the active rod 5. A first rectangular plate 17 passes through the surface of the threaded rod 16 and is threadedly connected to the threaded rod 16. When the motor 4 is started to drive the active rod 5 to rotate, the threaded rod 16 is also driven to rotate, causing the first rectangular plate 17 to slide up, which can drive the display screen 3 to slide up and rise from the outer shell 2 to display information.

[0029] A guide rod 18 is fixedly connected to the inner wall of the right bottom of the shell 2, and a second rectangular plate 19 is fixedly connected to the right surface of the display screen 3. The second rectangular plate 19 penetrates the guide rod 18 and is slidably connected to the guide rod 18. The display screen 3 is slidably connected to the inner wall of the shell 2 and the cleaning brush 15. When the display screen 3 is raised, it can slide on the guide rod 18 through the second rectangular plate 19, which plays a role of guiding and supporting the display screen 3, and helps to make the display screen 3 slide up and down stably.

[0030] The top of the base plate 1 is fixedly connected to a mounting frame 20, the bottom of the motor 4 is fixedly connected to the bottom inner wall of the mounting frame 20, the top surface of the motor 4 is fixedly connected to a support plate 21, the active rod 5 passes through the support plate 21 and is rotatably connected to the support plate 21, the driven rod 6 is rotatably connected to the support plate 21, the top of the mounting frame 20 is fixedly connected to the outer shell 2, and the support plate 21 supports the driven rod 6.

[0031] A connecting block 22 is fixedly connected to the surface of the shell 2 near the annular rack 10, and one end of the connecting block 22 away from the shell 2 is fixedly connected to the annular rack 10. A slide plate 23 is fixedly connected to the surface of the shell 2, and the slide plate 13 is slidably connected in the slide plate 23. The annular rack 10 can be supported by the connecting block 22, so that the gear 9 and the annular rack 10 can be stably meshed. Under the limitation of the slide plate 23, the slide plate 13 can make a horizontal reciprocating motion, thereby driving the cleaning brush 15 to wipe and clean the surface of the display screen 3 that is rising or falling.

[0032] A cavity is provided inside the cleaning brush 15, and a piston in the cavity of the cleaning brush 15 is connected to a piston rod 24. A water spray hole is provided on the surface of one side of the cleaning brush 15 close to the display screen 3. A water suction pipe 25 is fixedly connected to the left surface of the cavity of the cleaning brush 15, and a one-way valve is fixedly installed inside the water suction pipe 25. When the piston rod 24 performs piston motion in the cavity of the cleaning brush 15, water in the cavity of the cleaning brush 15 can be sprayed out from the water spray hole to the surface of the display screen 3 for auxiliary cleaning, and the one-way valve in the water suction pipe 25 can prevent water from flowing back to the water suction pipe 25.

[0033] One end of the water suction pipe 25 away from the cleaning brush 15 is fixedly connected to a water storage bucket 26, and the bottom of the water storage bucket 26 is fixedly connected to a placement plate 27, and the placement plate 27 is fixedly connected to the cleaning brush 15. A spring 28 is sleeved on the surface of the piston rod 24 near the outside of the cleaning brush 15, and an inclined plate 29 is fixedly connected to the outer surface of the piston rod 24.

A bearing plate 30 is fixedly connected to the surface of the shell 2, and a fixed plate 31 is fixedly connected to the end of the bearing plate 30 away from the shell 2. The fixed plate 31 is slidably connected to the inclined plate 29. When the cleaning brush 15 slides to the right, the inclined plate 29 will be driven to conflict with the fixed plate 31, so that the inclined plate 29 drives the piston rod 24 to compress the spring 28 and make a piston movement in the cavity of the cleaning brush 15. When the cleaning brush 15 slides to the left and the inclined plate 29 is disengaged from the fixed plate 31, the piston rod 24 and the inclined plate 29 can be reset by the spring 28, so that the piston rod 24 slides in the cleaning brush 15, and air is sucked from the water suction pipe 25, and the water in the water storage barrel 26 is sucked into the cavity of the cleaning brush 15, and sprayed out from the water spray hole again, thereby repeatedly cleaning the surface of the display screen 3.

[0035] In the utility model, when it is necessary to display information on the display screen 3, the starting motor 4 drives the active rod 5 to rotate. When the active rod 5 rotates, the driven rod 6 is driven to rotate through the synchronous belt 7, and at the same time, the threaded rod 16 is driven to rotate, so that the first rectangular plate 17 slides up, driving the display screen 3 to slide up, and at the same time, the driven rod 6 drives the first connecting rod 8 to rotate, so that the gear 9 is meshed with the annular rack 10, so that the gear 9 rotates and drives the second connecting rod 11 to rotate, and the second connecting rod 11 drives the slide plate 13 to do left and right reciprocating in the slide groove plate 23 through the connecting rod 12. The L-shaped plate 14 and the cleaning brush 15 slide back and forth, thereby driving the L-shaped plate 14 and the cleaning brush 15 to slide back and forth, and wiping the surface of the rising display screen 3 back and forth. At the same time, when the cleaning brush 15 slides to the right side of the shell 2, it drives the inclined plate 29 to contact the fixed plate 31, and cooperates with the spring 28 to make the inclined plate 29 drive the piston rod 24 to do reciprocating piston motion in the cavity of the cleaning brush 15, and absorbs water from the water storage barrel 26 through the suction pipe 25, and then sprays it from the water spray hole of the cleaning brush 15 onto the display screen 3 for auxiliary cleaning, so that the display screen 3 is cleaned more cleanly.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
