Description

Technical Field

[0001] The utility model relates to the technical field of poster display rack equipment, in particular to a lodging-resistant poster display rack. Background Art

[0002] Advertising, as the name suggests, is to make something known, that is, to inform the general public of something. When displaying advertisements on posters, display stands are usually used to display them, so as to attract consumers' attention. Generally, shopping malls, gas stations, banks and other places will place promotional posters of various products at the door to inform or attract customers to go in for consumption or to handle related services. Generally, posters are equipped with display stands for use, so that the posters can be clearly and flatly displayed to passing customers.

[0003] For example, the Chinese utility model patent with authorization announcement number CN220691660U discloses a lodging-resistant poster display stand, which relates to the technical field of poster display stands and includes a display board and a supporting board. The supporting boards are two in number and symmetrically arranged on both sides of the display board. A support board is fixedly provided in the middle of the top surface of the supporting board. An adjustment mechanism is provided at one end of the supporting board away from the supporting board. The adjustment mechanism is used to fix the display board to the end of the supporting board and adjust the angle of the display board. The utility model, through the setting of the adjustment mechanism, can fix the display board and adjust the display angle of the display board, thereby adjusting the angle of the poster display to facilitate viewing by pedestrians. The setting of the counterweight mechanism increases the stability and load-bearing capacity of the device, allowing the supporting board to be placed more firmly on the ground to avoid movement caused by external factors such as wind. In addition, the counterweight plate can also balance the center of gravity of the device, making the entire device more stable.

[0004] The following problems exist in the use of the above-mentioned authorized patent:

[0005] The bottom of the anti-lodging poster display stand occupies a small area and is prone to tipping over, resulting in poor wind resistance. The display board is fixed by friction after the angle is rotated, which makes it easy to loosen and cannot achieve a stable and fixed effect. When the wind is strong, the angle of the display board is prone to change, affecting the display effect. Moreover, the counterweight plate is not limited to the left and right positions, so it is easy to fall off the disc, which can easily injure the feet or damage tiles.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original anti-lodging poster display stand. Utility Model Content

[0039] Working principle: When using the anti-lodging poster display stand, according to Figure 6-9 As shown, insert your finger into the pull hole 10 and pull the card rod 9 hard to move the card rod 9 away from the first card slot 8. At the same time, the card rod 9 drives the movable block 13 to move inside the groove 11, so that the spring 12 is compressed. Then push the card rod 9, and the card rod 9 drives the end of the second carrier plate 5 to move out from the inside of the slide groove 4 until the end of the card rod 9 is aligned with the second card slot 14. Release the card rod 9. Under the elastic force of the spring 12, the end of the card rod 9 is engaged with the second card slot 14, completing the fixation of the position of the second carrier plate 5 after moving. Figure 7 become Figure 8 state, thereby increasing the floor space at the bottom of the anti-lodging poster display stand and reducing the chance of the anti-lodging poster display stand tipping over. Similarly, the second carrying plate 5 can be stored inside the first carrying plate 3, which can reduce the floor space at the bottom of the anti-lodging poster display stand and facilitate the carrying and transportation of the anti-lodging poster display stand.

[0040] according to Figure 1-5As shown, a poster is placed inside the placement slot 19, and the poster is fixed inside the placement slot 19 by the attraction between the permanent magnet 20 and the iron plate 21. Then the handle 27 is rotated, and then the handle 27 drives the screw rod 25 to rotate. Since the lower end of the screw rod 25 is rotatably mounted with a tooth block 26 through a bearing, and the fixing plate 24 and the screw rod 25 are threadedly connected, and the guide rod 28 and the fixing plate 24 are slidably connected, the screw rod 25 drives the tooth block 26 to move upward without rotating until the lower end of the tooth block 26 is separated from the gear 23. Then the display board 18 is rotated until the angle of the poster on the display board 18 is adjusted. Then the handle 27 is rotated in the opposite direction, so that the tooth block 26 moves downward and engages with the top of the gear 23, completing the fixation of the gear 23, thereby fixing the second rotating shaft 22, the display board 18 and the first rotating shaft 17.

[0041] according to Figure 1 and Figure 10 As shown, pick up the counterweight plate 31 and make the counterweight plate 31 be located above the anti-slip rod 34, and at the same time make the reserved opening 32 on the counterweight plate 31 engage with the vertical rod 29, and then install the through hole 33 on the counterweight plate 31 on the anti-slip rod 34 to complete the installation of the counterweight plate 31.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
