Description

Technical Field

[0001] This utility model relates to the field of advertising devices, specifically an advertising device. Background Technology

[0002] The Industrial Engineering major aims to cultivate students' ability to solve practical problems, improve production efficiency, and reduce costs. However, in actual educational promotion, it is often necessary to popularize and publicize the Industrial Engineering major. Therefore, a promotional device is needed.

[0003] A publicity device, disclosed in CN220357773U, addresses the problem that existing publicity boards, with their fixed dimensions, cannot place large maps and images flat, causing information obstruction. The proposed solution includes an upper mounting plate. Two screw rods are threadedly mounted on both sides of the bottom of the upper mounting plate. Adjusting sleeves are threadedly mounted on the outer bottom ends of the two screw rods. Two screw rods are threadedly mounted on the inner bottom ends of the two adjusting sleeves. A lower mounting plate is threadedly mounted on the bottom ends of the two screw rods. Hinges secure the front sides of both the upper and lower mounting plates. This invention uses two adjusting sleeves to control the extension and retraction of the screw rods, thereby adjusting the distance between the upper and lower mounting plates and ensuring that maps and images are placed flat. Furthermore, existing publicity devices have the following drawbacks in use:

[0004] (1) The existing publicity devices lack a mobile structure. When conducting publicity for industrial engineering, it is often necessary to transport the device to a designated area for publicity. The lack of a mobile structure means that users need to carry it manually, which not only consumes a lot of time and energy, but also significantly reduces work efficiency.

[0005] (2) The existing publicity devices lack protection. When the publicity devices are used for publicity outdoors, they are inevitably exposed to wind and sun. The lack of protection makes the publicity materials easy to be damaged, which not only shortens the service life of the publicity materials, but may also affect the publicity effect.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Push the device to the designated location for promoting industrial engineering, screw in bolt 207, bolt 207 pushes the abutment plate 208 to abut the rotating wheel 206, and the device is fixed. The extension and retraction of the damping rod 203 and spring 204 at the top of the moving structure 2 provides shock absorption when the device moves, resulting in high work efficiency and ease of use. Move the fixed plate 12 out of the empty slot 1001, open the transparent plate 9, and post the promotional materials for industrial engineering in the bulletin board 8. Close the transparent plate 9 and rotate the fixed plate 12 back into the empty slot 1001. The device is fixed, and the protective shell 6 and the shielding structure 7 can provide protection for the advertising materials in the bulletin board 8. When it is necessary to shield the sun, the motor 702 causes the lead screw 701 to rotate. The lead screw 701 drives the first movable seat 703 and the two second movable seats 705 to move forward, thereby causing the top shielding canopy 707 to shield the bulletin board 8. When it is necessary to store it, the motor 702 causes the lead screw 701 to rotate in the opposite direction, driving the first movable seat 703 and the two second movable seats 705 to retract, thereby causing the shielding canopy 707 to retract back to the top of the protective shell 6. It saves space and is easy to operate. When it is necessary to adjust the display height, the electric telescopic rod 4 can be raised and lowered through the control panel 3.
