[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: a rolling display information board, which includes a bracket 1. A dust-proof cover 2 is fixedly connected to the upper surface of the bracket 1. A support column 3 is rotatably connected inside the dust-proof cover 2. A protective shell 12 is fixedly connected to the upper surface of the support column 3. A rolling display board 17 is arranged inside the protective shell 12. A motor 4 is fixedly connected inside the bracket 1. A bottom plate 5 is fixedly connected to the upper surface of the bracket 1. The dust-proof cover 2 is arranged on the upper surface of the bottom plate 5. A tray 6 is rotatably connected to the upper surface of the bottom plate 5. The output end of the motor 4 is fixedly connected to the side wall of the tray 6. A first turntable 8 is fixedly connected to the upper surface of the tray 6. A limit post 7 is fixedly connected to the upper surface of the tray 6. A connecting column 9 is rotatably connected to the upper surface of the bottom plate 5. The connecting column 9 is fixedly connected inside the support column 3. A second turntable 10 is fixedly connected to the side wall of the connecting column 9. The side walls of the first turntable 8 and the second turntable 10 are in contact with each other. A sliding groove 11 is opened inside the second turntable 10. The side wall of the limit post 7 is slidably connected inside the sliding groove 11. An auxiliary component is arranged on the side wall of the bracket 1. The auxiliary component includes a universal wheel 26 and a ventilation hole 27. The universal wheel 26 is arranged on the lower surface of the bracket 1. The ventilation hole 27 is opened inside the bracket 1.

[0033] During the operation of the device, first start the motor 4. When the motor 4 starts to work, its output end drives the tray 6 to rotate. The rotation of the tray 6 drives the limit post 7 on its upper surface to rotate, and at the same time drives the first turntable 8 to rotate. When the limit post 7 rotates into the sliding groove 11, it further drives the rotation of the second turntable 10. Because of the special position of the limit post 7, every time the limit post 7 slides inside the sliding groove 11, the second turntable 10 will rotate 180 degrees once. The second turntable 10 drives the connecting column 9 to rotate, and then the connecting column 9 drives the support column 3 to rotate, and finally the support column 3 drives the protective shell 12 to rotate. Finally, the protective shell 12 realizes an indirect 180-degree rotation.

[0034] Refer to Figure 3 - Figure 4 , a cover plate 13 is arranged on the side wall of the protective shell 12. A first rotating column 14 is fixedly connected inside the protective shell 12. A second rotating column 15 is fixedly connected to the side wall of the cover plate 13. A connecting rod 16 is rotatably connected between the first rotating column 14 and the second rotating column 15. A handle 18 is fixedly connected to the side wall of the cover plate 13. A clamping groove 19 is opened on the side wall of the protective shell 12. A fixing plate 20 is arranged inside the protective shell 12. The side wall of the fixing plate 20 is fixedly connected inside the clamping groove 19. A first fixing block 22 is fixedly connected to the side wall of the fixing plate 20. A female buckle 24 is rotatably connected between the first fixing blocks 22. A second fixing block 23 is fixedly connected to the side wall of the female buckle 24. A spring 21 is arranged between the fixing plate 20 and the second fixing block 23. A male buckle 25 is fixedly connected to the side wall of the cover plate 13. The male buckle 25 is engaged with the female buckle 24.

[0035] When performing the replacement operation of the rolling display board 17, the operator first needs to hold and pull the handle 18. By applying appropriate pressure to the handle 18, the spring 21 will contract under the extrusion effect of the sub - buckle 25. As the spring 21 contracts, the pressure originally exerted by the spring 21 on the mother - buckle 24 disappears, causing the sub - buckle 25 to slide out from the inside of the mother - buckle 24. During this process, one end of the connecting rod 16 rotates inside the first rotating column 14, and the other end of the connecting rod 16 rotates correspondingly inside the second rotating column 15. Through the rotation of the connecting rod 16, finally, the cover plate 13 is moved to one side of the protective shell 12. After the position of the cover plate 13 is adjusted, the replacement work of the rolling display board 17 can be started.

[0036] Working principle: When using this device, first start the motor 4. The output end of the motor 4 drives the tray 6 to rotate. When the tray 6 rotates, it drives the limit post 7 on its upper surface to rotate. The tray 6 drives the first turntable 8 to rotate. When the limit post 7 rotates into the sliding groove 11, the second turntable 10 starts to rotate. Due to the special position of the limit post 7, every time the limit post 7 slides inside the sliding groove 11, the second turntable 10 rotates 180 degrees. The second turntable 10 drives the connecting column 9 to rotate, and the connecting column 9 drives the support column 3 to rotate. The support column 3 drives the protective shell 12 to rotate, thereby indirectly rotating the protective shell 12 by 180 degrees. When it is necessary to replace the rolling display board 17, first pull the handle 18 to apply pressure to it. At this time, the spring 21 contracts under the extrusion of the sub - buckle 25, and the mother - buckle 24 loses pressure, so that the sub - buckle 25 slides out. At this time, one end of the connecting rod 16 rotates inside the first rotating column 14, and the other end of the connecting rod 16 rotates inside the second rotating column 15, so that the cover plate 13 is moved to one side of the protective shell 12, and then the rolling display board 17 can be replaced.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
