[0017] In the description of the utility model, it should be noted that unless otherwise clearly defined and limited, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0018] Combined with the attached Figure 1 , Figure 2 , an ecological civilization education and publicity device, including a bottom plate 1. On both sides of the upper surface of the bottom plate 1, telescopic rods 2 are provided. Between the telescopic rods 2 above, a display rack 3 is provided. The display rack 3 is provided with a hollow interior. Between the opposite side surfaces in the display rack 3, two driving rollers 4 that are symmetrically arranged up and down are rotatably provided. Transmission wheels 5 are provided on the driving rollers 4. A transmission belt 6 is provided between the transmission wheels 5. An activity cavity 7 is provided in the display rack 3.

[0019] Combined with the attached Figure 2 , Figure 3 , a driving mechanism capable of rotating one of the driving rollers 4 is provided in the activity cavity 7. The driving mechanism includes a motor 1 8 located in the activity cavity 7, a turntable 9 connected to the output end of the motor 1 8, a driving rod 10 located on the turntable 9, a driving part 11 cooperating with the driving rod 10. At the central position of the side surface of the driving part 11 close to the driving roller 4, a connecting shaft 12 connecting the driving roller 4 is provided. The driving part 11 includes a solid part 13 and a driving groove 14. The solid part 13 is rotatably connected to the activity cavity 7. Four driving grooves 14 are evenly distributed in the circumferential direction. The driving grooves 14 are respectively located at the four quadrant point positions. The driving grooves 14 cooperate with the driving rod 10 provided on the turntable 9 to drive the solid part 13 to rotate. Arc-shaped recessed parts 15 are provided on the solid part 13 and between every two adjacent driving grooves 14. A semi-circular limiting plate 16 is provided on the turntable 9. The arc-shaped recessed parts 15 are in contact with the semi-circular limiting plate 16.

[0020] Combined with the attached Figure 1, a lifting mechanism capable of adjusting the height of the display rack 3 is provided on the bottom plate 1. The lifting mechanism includes a second motor 17 located above the bottom plate 1. A first gear 18 is provided at the output end of the second motor 17. A second gear 19 meshing with the first gear 18 is rotatably provided on the bottom plate 1. A screw rod 20 is provided at the center of the second gear 19. A moving plate 21 is threadedly connected to the screw rod 20. A baffle 23 for preventing the moving plate 21 from falling off is provided above the screw rod 20. Connecting rods 22 are provided on both sides of the upper surface of the moving plate 21. The other ends of the connecting rods 22 are connected to the display rack 3.

[0021] When the present utility model is specifically implemented, first, the annular promotional page is sleeved between the two driving rollers, and then the first motor is started. The first motor drives the turntable to rotate. The turntable drives the driving rod connected thereto to rotate. The driving rod and the driving groove cooperate with each other, so that the driving member rotates by a certain angle. The driving member drives the connecting shaft to rotate. The connecting shaft drives the driving roller to rotate. The driving rollers are driven by the transmission belt between the transmission wheels, so that the two driving rollers rotate simultaneously, thereby driving the promotional page to be scrolled and displayed.

[0022] When the driving rod is disengaged from the driving groove, the driving member stops rotating, that is, the promotional page stops scrolling, leaving people with a certain amount of time to view the content on the promotional page. At the same time, since the semi-circular limiting disk can fit with the arc-shaped recessed portion, when the driving rod rotates out of the driving groove, the driving member no longer rotates. The semi-circular limiting disk rotates along the arc-shaped recessed portion, which has a certain limiting effect on the driving member, avoiding the driving member from rotating when the driving rod is disengaged from the driving groove, resulting in the next driving groove being unable to cooperate with the driving rod. When the driving rod rotates to cooperate with the next driving groove, the promotional page is rotated to the other side for conversion, thereby realizing the scrolling and promotional effect of the promotional page. This structure can realize the intermittent rotation of the driving member, leaving a certain amount of time for people to view, so as to more effectively display the content on the promotional page.

[0023] Then the second motor is started. The second motor drives the first gear to rotate. The first gear meshes with the second gear, driving the screw rod to rotate. And under the limiting effect of the connecting rod on the moving plate, the moving plate moves up and down to adjust the height of the display rack.

[0024] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
