[0028] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of this utility model's educational publicity device.

[0029] like Figure 1-6 As shown, this utility model discloses a college education and publicity device, comprising two height-adjustable support frames 1. Each support frame 1 includes support legs 6 and lifting legs 7 that are slidably connected vertically to the inner cavity at the top of the support legs 6. The lower sidewall of the lifting legs 7 has multiple equally spaced mounting holes 15 along its vertical direction. The top sidewall of the support legs 6 has a fixing hole 16 corresponding to the mounting holes 15. The fixing hole 16 and the mounting hole 15 are fixedly connected by bolts. The vertical slidable connection between the lifting legs 7 and the support legs 6 facilitates height adjustment of the main board 2 during installation, improving the device's flexibility. Furthermore, the fit between the fixing hole 16 and the mounting hole 15 facilitates fixing the support legs 6 and the lifting legs 7. A base plate 10 is provided at the bottom of the support legs 6, with through holes at the four corners of the base plate 10. The base plate 10 facilitates fixing the support frame 1 to the ground.

[0030] A motherboard 2 is fixedly installed between two support frames 1. Two movable plates 4 are slidably connected to the front and rear surfaces of the motherboard 2. A rain shield 3 is set between the tops of the two support frames 1. A groove 11 is set in the middle part of the front and rear surfaces of the motherboard 2. A U-shaped groove 5 is set on the side of the movable plate 4 away from the motherboard 2. The groove 11 and the U-shaped groove 5 are designed to facilitate pasting the educational publicity content of colleges and universities into the groove 11 and the U-shaped groove 5. The front and rear sides of the main board 2 are provided with trapezoidal grooves 12 with closed ends along their length. The upper and lower side walls of the movable plate 4 are provided with trapezoidal plates 17 corresponding to the trapezoidal grooves 12. The trapezoidal plates 17 are slidably connected to the trapezoidal grooves 12. The cooperation between the trapezoidal plates 17 and the trapezoidal grooves 12 facilitates the sliding of the movable plate 4. When there is little content to be promoted, the movable plate 4 can be combined with the main board 2, which can effectively reduce the space occupied by the device. When there is a lot of content to be promoted, the corresponding number of movable plates 4 can be unfolded as needed, so that the device can accommodate more educational promotional content. It is highly practical and easy to operate.

[0031] The front and rear side walls of the lifting leg 7 are each provided with two vertically distributed limiting blocks 13. The distance between the two limiting blocks 13 matches the width of the moving plate 4. Through the setting of the upper and lower limiting blocks 13, when the moving plate 4 is pulled open, the upper and lower sides of the moving plate 4 will contact the upper and lower limiting blocks 13. The limiting blocks 13 not only limit the moving plate 4, but also support it, making the moving plate 4 more stable. The left and right ends of the main board 2 are each provided with two vertically distributed mounting plates 8. The side of the lifting leg 7 opposite to the main board 2 is provided with mounting openings 14 corresponding to the mounting plates 8. The front side wall of the lifting leg 7 is provided with a notch 9 above the mounting opening 14, which is connected to the mounting opening 14. The mounting plate 8 extends into the mounting opening 14 through the notch 9 and is fixedly connected to the lifting leg 7 by bolts. Through the cooperation between the mounting plate 8, the notch 9, and the mounting opening 14, the main board 2 can be disassembled and installed without disassembling the support frame 1, making the disassembly and assembly of the main board 2 more convenient and quick.

[0032] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
