[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by providing a traction disc and an L-shaped plate, when multiple posters need to be unfolded, by releasing the fixed operating rod, the traction disc moves downward due to gravity. This causes the four sets of hinged rods and four sets of L-shaped plates to hinge with each other, causing the four sets of L-shaped plates to simultaneously drive the four sets of rods A to unfold outward. This, in turn, pulls the connecting rod to pull the poster out from the insertion rod and keeps the poster taut through the locking rod B. This achieves rapid unfolding and stable tension of the posters, reduces the complexity of manual operation, improves unfolding efficiency, and ensures the flatness and stability of the posters. It is suitable for large-scale or emergency use.

[0023] 2. In this utility model, by fixing the plug-in rod to the inner surface of the rod body A with bolt A, the plug-in rod can be quickly removed and replaced when the poster is replaced by unscrewing bolt A. This allows for quick and safe removal of the plug-in rod and replacement of the poster, reducing cumbersome operating steps and improving work efficiency. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figure 1 , Figure 3 , Figure 5 This utility model provides an embodiment of a community emergency temporary publicity device, comprising a column 1. A traction disc 6 is slidably connected to the inner surface of the column 1, enabling the traction disc 6 to move vertically along the inner surface of the column 1. A hinge 10 is slidably connected to the inner surface of the traction disc 6, enabling the hinge 10 to move laterally along the inner surface of the traction disc 6. Furthermore, when the traction disc 6 moves vertically, it can drive the hinge 10 to move together. An L-shaped plate 9 is hinged to the left side of the inner surface of the hinge 10, so that when the hinge 10 is driven vertically by the traction disc 6, it can drive the L-shaped plate 9 to move together through the hinge. The bottom of the inner surface of the L-shaped plate 9 is hinged to the top of the inner surface of the column 1, so that when the L-shaped plate 9 is moved by the hinge 10, it can flip along the top of the inner surface of the column 1. The L-shaped plate 9 is L-shaped, so that when the hinge 10 moves vertically, it can drive the L-shaped plate 9 to flip along the top of the inner surface of the column 1. The bottom of the outer surface of the L-shaped plate 9 is fixedly connected to the rod A2, so that when the L-shaped plate 9 flips, it can drive the rod A2 to flip together. The inner surface of the rod A2 is slidably connected to the insertion rod 12, so that the insertion rod 12 can be moved laterally along the inner surface of the rod A2 and pulled out.

[0038] Reference Figure 2 , Figure 4 , Figure 6 The inner surface of the plug rod 12 is elastically connected to the rotating column 11 via a spiral spring 13, so that the rotating column 11 can always rotate in the specified direction without being affected by external force. The outer surface of the rotating column 11 is provided with a poster 5, so that when the poster 5 moves outward, it can drive the rotating column 11 to rotate. The bottom end of the outer surface of the traction disc 6 is fixedly connected to the traction column 16, so that when the traction column 16 moves vertically, it can drive the traction disc 6 to move together. The bottom end of the outer surface of the traction column 16 is fixedly connected to the operating rod 4, so that when the operating rod 4 moves vertically, it can drive the traction column 16 to move together. Furthermore, by providing the operating rod 4, the traction column 16 can be operated from outside the column body 1. The outer surface of the column body 1 is provided with a spreading component, so that the poster 5 can be tightened by the spreading component to prevent it from being blown by the wind and causing the image on the poster 5 to be unclear.

[0039] Reference Figure 6 - Figure 8 The expansion assembly includes a connecting rod 7, a hook 8, a rod body B3, and a connecting column 14. One end of the poster 5 is fixedly connected to the outer surface of the rotating column 11, so that when the rotating column 11 is driven to rotate by the spiral spring 13, it can roll up the poster 5. The other end of the poster 5 is fixedly connected to the left side of the outer surface of the connecting rod 7, so that when the connecting rod 7 is pulled, the poster 5 can be pulled out of the insertion rod 12. The top of the outer surface of the hook 8 is hinged to the right side of the outer surface of the connecting rod 7, so that when the connecting rod 7 is vertical or parallel, the hook 8 can always hang downward due to gravity, and when the hook 8 is fixed, it can drive the connecting rod 7 to be fixed in a designated position. The effect is that the top of the outer surface of the rod B3 is hinged to the bottom of the outer surface of the column 1, allowing the rod B3 to unfold outward along the bottom of the outer surface of the column 1. The inner surface of the rod B3 is fixedly connected to the connecting column 14, allowing the rod B3 to move together with the connecting column 14. The bottom of the outer surface of the hook 8 is engaged with the outer surface of the connecting column 14, allowing the connecting rod 7 to be fixed in a designated position by engaging the hook 8 with the outer surface of the connecting column 14. Multiple sets of hooks 8 and connecting columns 14 are provided, so that when multiple sets of hooks 8 are engaged with multiple sets of connecting columns 14, the connecting rod 7 and the poster 5 can be subjected to a more uniform traction force, preventing the poster 5 from wrinkling.

[0040] Reference Figure 6 , Figure 9 - Figure 10One end of the spiral spring 13 is fixedly connected to the inner surface of the plug rod 12, and the other end of the spiral spring 13 is fixedly connected to the outer surface of the rotating column 11. This allows the rotating column 11 to retract the poster 5 through the elastic force of the spiral spring 13 when the hook 8 is released from the connecting column 14. This retraction of the poster 5 also causes the connecting rod 7 to return to its original position. A bolt B17 is threaded through and connected to the left side of the inner surface of the rod A2, allowing the bolt B17 to be fixed at a designated position on the rod A2 via the threaded connection. The bottom end of the outer surface of bolt B17 is engaged with the left side of the outer surface of the plug rod 12, so that the plug rod 12 can be fixed inside the rod body A2 by engaging with bolt B17. The bottom end of the outer surface of column 1 is fixedly connected to limit plate 18, which provides fixed support for limit plate 18 through the bottom of the outer surface of column 1. The bottom end of the outer surface of limit plate 18 is in contact with the left side of the outer surface of the top of rod B3, so that when rod B3 is unfolded outward, it can be restricted by limit plate 18 and can only be rotated to a designated position.

[0041] Reference Figure 8 The inner surface of the operating lever 4 is slidably connected to a bolt A15, which allows the bolt A15 to move laterally along the inner surface of the operating lever 4. The outer surface of the bolt A15 is slidably connected to the bottom of the inner surface of the column 1, which allows the operating lever 4 to be fixed in a designated position by the bolt A15 passing through the bottom of the inner surface of the column 1. This allows the operating lever 4 to drive the traction column 16 to be fixed in a designated position.

[0042] Working principle: When using the device, first place the device in a suitable position, then loosen the connection between bolt A15 and operating rod 4. Then, operating rod 4 and traction column 16 move downwards due to gravity, which also drives traction disc 6 downwards. As traction disc 6 moves downwards, it drives hinge 10 downwards as well. Due to the hinge of L-shaped plate 9 and hinge 10, hinge 10 causes L-shaped plate 9 to rotate outwards along the top of the inner surface of column 1. Furthermore, hinge 10... The L-shaped plate 9 can slide along the inner surface of the traction disc 6, thus offsetting the motion interference caused by the flipping of the L-shaped plate 9. When the L-shaped plate 9 flips, it will simultaneously drive the rod A2 to flip as well. When the rod A2 flips to the designated position, it pulls the connecting rod 7 downward, causing the poster 5 inside the plug rod 12 to be pulled out together. Then, the rod B3 is flipped upward, and the hook 8 at the bottom of the connecting rod 7 is engaged with the connecting post 14 inside the rod B3, thus opening the poster 5 to achieve the purpose of advertising.

[0043] When it is necessary to replace the poster 5, first unscrew the bolt B17, then pull the plug rod 12 out of the rod body A2, so that the plug rod 12 pulls the poster 5 out together. Then insert the poster 5 to be replaced and the plug rod 12 into the rod body A2 together, and then tighten the bolt B17.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
