DETAILED DESCRIPTION

[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] like Figure 1-4As shown, the utility model provides a technical solution: an achievement display and publicity rack, comprising a protective shell 1, the bottom of the protective shell 1 is fixedly connected to a supporting structure 3, the supporting structure 3 comprises two supporting plates 31, the two supporting plates 31 are fixedly connected to the bottom of the protective shell 1, an opening 5 is provided above the protective shell 1 and in front of the protective frame 2, and identification stickers are provided above the protective shell 1 and on both sides of the opening 5. The two identification stickers can be used to place brief introductions of administrative achievements and background introductions, which are convenient for personnel to watch and switch according to needs, and the bottoms of the two supporting plates 31 are fixedly connected to the same bottom plate 32. The supporting plates 31 can play a role in erecting the protective shell 1, and the bottom plate 32 can improve the stability of the device. There is a chain transmission structure 6, which is enclosed by a protective shell 1, so as to protect the chain transmission structure 6. The chain transmission structure 6 includes two first sprockets 61, which are engaged and driven by a chain 62. The first sprocket 61 can support the chain 62 and enable the two first sprockets 61 to maintain the smooth movement of the chain 62. The two sides of the chain 62 are also engaged and driven with the two second sprockets 9. An operating rod 63 is fixedly connected to the chain 62. The operating rod 63 can provide a force point for personnel to facilitate personnel to control the movement of the chain 62. The operating rod 63 passes through the opening 5 upward. The opening 5 can provide an active point for the operating rod 63, so that the operating rod 63 can move smoothly, and the opening 5 allows the operating rod 63 to extend. To facilitate personnel operation, a rotating shaft 64 is fixedly connected to the first sprocket 61, and the rotating shaft 64 rotates in the first bearing 65. The first bearing 65 can maintain the stable rotation of the rotating shaft 64, so that the first sprocket 61 can rotate stably. The first bearing 65 is fixed in the protective shell 1. The two sides of the chain transmission structure 6 are respectively engaged with the two second sprockets 9. The diameter of the first sprocket 61 is greater than the diameter of the second sprocket 9, so that the torque ratio of the first sprocket 61 is greater than the torque ratio of the second sprocket 9, so that the transmission ratio of the second sprocket 9 is higher, the transmission efficiency is improved, and the number of rotations of the second sprocket 9 is increased, and the operation of switching the promotional surface 8 can be smoothly realized without the first sprocket 61 driving one circle. A transmission roller 7 is fixedly connected to the second sprocket 9, and the two transmission rollers 7 are transmitted through the conveyor belt 11 Dynamic connection, the transmission roller 7 can realize the movement of the conveyor belt 11, so that the movement of the conveyor belt 11 can smoothly realize the operation of switching the promotional surface 8. Both sides of the conveyor belt 11 are provided with promotional surfaces 8. The promotional surfaces 8 can be pressed with rubber strips to fix the promotional surfaces 8 to meet the needs of replacement. It can also be fixed by snap-fitting. The upper and lower ends of the transmission roller 7 are respectively rotatably connected to the two second bearings 10. The second bearings 10 can fix the transmission roller 7 to maintain the stability of the transmission roller 7, and the second bearings 10 can also ensure the smooth rotation of the transmission roller 7, so that the transmission roller 7 can smoothly drive the conveyor belt 11 to move. The upper second bearing 10 and the lower second bearing 10 are respectively fixedly mounted on the protective frame 2 and the protective shell 1. The protective frame 2 is fixedly connected to the protective shell 1.A window panel 4 is provided in front of the protective frame 2. The window panel 4 is transparent, which makes it convenient for personnel to display the results. In addition, the window panel 4 and the protective frame 2 can cooperate to seal and protect the promotional surface 8 to prevent damage to the promotional surface 8. Secondly, the window panel 4 is connected to the protective frame 2 by a hinge, so that the window panel 4 can be opened, making it easy to replace the promotional surface 8.

[0026] The working principle of this utility model is:

[0027] When switching the promotional surface 8, the operating rod 63 is moved, and the operating rod 63 drives the chain 62 to move, so that the chain 62 engages with the first sprocket 61 and the second sprocket 9 for transmission. Since the first sprocket 61 can increase the transmission ratio of the second sprocket 9 through the chain 62, the second sprocket 9 drives the transmission roller 7 to rotate, and the transmission roller 7 drives the conveyor belt 11 to rotate, and the conveyor belt 11 drives the promotional surface 8 to move, so that the front and rear positions of the front and rear promotional surfaces 8 are switched.

[0028] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense.
