Description

Technical Field

[0001] This utility model relates to the field of display equipment technology, and in particular to a roll-up banner with strong wind resistance. Background Technology

[0002] A roll-up banner, also known as a poster stand or display stand, is a type of vertical poster commonly found in high-traffic street passages. It assists individual vendors in roadshow promotions or temporary stalls. The main materials for roll-up banner stands are plastic or aluminum alloy, and the poster material is photo paper. Alternatives to roll-up banners include street banners, road flags, posters, and stickers.

[0003] Currently, there is a difference between outdoor and indoor use of roll-up banners. When used outdoors, strong winds can easily blow the roll-up banner over, causing damage to the banner and the posters on its surface, resulting in poor advertising efficiency.

[0004] A search revealed that patent publication number CN115512624B provides an outdoor roll-up banner with anti-tipping function. This solution involves energizing the top rod body, causing the induction coil to emit magnetism. Simultaneously, the support frame is magnetically attached to the surface of the receiving column. When there is strong wind, the poster body causes the rotating base to slide within the slide rail until it is stopped by the limiting block. At this point, the poster forms a 45° angle with the wind resistance from the front, reducing the wind force on the surface of the support frame and making it less likely to be blown over and damaged. As the wind gradually weakens, the poster returns to its initial shape under the force of the torque spring, presenting itself flat to the viewer again. After the poster returns to its original position, the first magnet at the bottom of the slider is attracted by the second magnet, thus completing the limiting and reducing the possibility of the poster rotating during normal placement.

[0005] Based on the above search and analysis of existing technologies, it was found that existing outdoor roll-up banners similar to those disclosed above have relatively complex structures and cannot protect the poster in strong winds, thus their practicality needs improvement. Therefore, a wind-resistant roll-up banner is proposed to address these issues. Utility Model Content

[0006] The purpose of this application is to provide a wind-resistant roll-up banner to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: a wind-resistant roll-up banner, including a poster and an elastic retractable device for storing the poster. A rotating base is installed at the lower end of the elastic retractable device, and a fixed base is rotatably installed at the lower end of the rotating base. A reset torsion spring is installed between the rotating base and the fixed base.

[0008] The free end of the poster is located outside the elastic retractable device and is fixed with a fixing plate. A support rod is vertically installed on the upper end of the rotating seat. The fixing plate is vertically slidably sleeved on the outside of the support rod. A magnetic ring that attracts the fixing plate is installed at the top of the support rod.

[0009] As a further supplement to this solution, the support rod is cylindrical, and at least two support rods are provided.

[0010] As a further supplement to this solution, a first threaded post is coaxially integrated at the top of the support rod, and the diameter of the first threaded post is smaller than the diameter of the support rod. The magnetic ring is threaded onto the outside of the first threaded post.

[0011] As a further supplement to this solution, a fixing block is fixed to the side end of the flexible retractable device, and a second threaded post is coaxially and integrally provided at the bottom end of the support rod. The threaded post of the second threaded post passes through the fixing block, and a screw hole for threaded connection of the second threaded post is provided at the upper end of the rotating seat.

[0012] As a further supplement to this solution, the upper end of the fixed base is provided with an annular groove for the second threaded column to rotate.

[0013] As a further supplement to this solution, the center of rotation between the rotating base and the fixed base falls on the straight line of the width of the poster in the unfolded state, and is offset from the middle position of the width of the poster in the unfolded state.

[0014] As a further supplement to this scheme, the bottom end of the second threaded column is set as a tapered head.

[0015] As a further supplement to this solution, a flexible sealing ring is fixed at the opening of the retractable device, and the flexible sealing ring is fitted and sleeved on the outside of the poster.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] 1. In this utility model, by means of the design of the fixing plate and the magnetic ring attracting each other, the fixing plate is pulled upward to pull the poster out of the elastic retractable device, so that the fixing plate and the magnetic ring attract each other, which can realize the quick fixing of the poster.

[0018] 2. In this utility model, by rotating the rotating seat and the fixed base in a rotating connection and using a reset torsion spring, when the wind blows the poster in a strong wind, the wind resistance formed by the poster will cause the poster and the rotating seat to rotate relative to the fixed base. After the poster rotates, the side of the poster faces the windward side, which can reduce the wind resistance and thus reduce the damage to the poster. After the wind weakens, the poster and the rotating seat will automatically reset under the action of the reset torsion spring.

[0019] 3. In this utility model, through the design of the fixed plate and the magnetic ring attracting each other, when the wind force is too strong and the poster shakes violently, the fixed plate is pulled by the poster and separates from the magnetic ring. Then, the poster is automatically stored in the elastic retractable device under the action of the elastic retractable device, so as to avoid further damage to the poster.

[0026] 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.

[0027] Example: Reference Figure 1-4The illustrated roll-up banner with strong wind resistance includes a poster 5 and an elastic roll-up device 4 for storing the poster 5. The elastic roll-up device 4 adopts a conventional elastic roll-up structure in the prior art, such as the structure of a conventional spring tape measure. A rotating base 2 is installed at the lower end of the elastic roll-up device 4, and a fixed base 1 is rotatably installed at the lower end of the rotating base 2. A return torsion spring 9 is installed between the rotating base 2 and the fixed base 1. The free end of the poster 5 is located outside the elastic roll-up device 4 and is fixed with a fixing plate 6. A support rod 3 is vertically installed at the upper end of the rotating base 2. The support rod 3 is cylindrical and at least two support rods 3 are provided. The fixing plate 6 is vertically slidably sleeved on the outside of the support rod 3. A magnetic ring 7 that attracts the fixing plate 6 is installed at the top of the support rod 3.

[0028] Pull the fixing plate 6 upwards to pull the poster 5 out of the elastic retractable device 4, causing the fixing plate 6 to attract the magnetic ring 7. The fixing plate 6 itself can be made of ferromagnetic material, or a ferromagnetic structure can be fixed to the upper surface of the fixing plate 6 to fix the fixing plate 6 and the magnetic ring 7 to achieve a stable display of the poster 5. When it is windy, if a strong wind blows the poster 5, the wind resistance created by the poster 5 will cause the poster 5 and the rotating base 2 to rotate relative to the fixed base 1. After rotation, the side of the poster 5 faces the windward side, which can reduce wind resistance and reduce damage to the poster 5. After the wind weakens, the poster 5 and the rotating base 2 will automatically return to their original positions under the action of the return torsion spring 9. When the wind is too strong and the poster 5 shakes violently, the fixing plate 6 will be pulled away from the magnetic ring 7 by the poster 5. After that, the poster 5 will automatically be stored in the elastic retractable device 4 under the action of the elastic retractable device 4 to avoid further damage to the poster 5.

[0029] To ensure that when a strong wind blows the poster 5, the poster 5 and the rotating base 2 can rotate relative to the fixed base 1, the center of rotation between the rotating base 2 and the fixed base 1 lies on the straight line of the width of the poster 5 in its unfolded state, and is offset from the middle position of the width of the poster 5 in its unfolded state.

[0030] The top of the support rod 3 is coaxially integrated with a first threaded post 31, and the diameter of the first threaded post 31 is smaller than the diameter of the support rod 3. The magnetic ring 7 is threaded onto the outside of the first threaded post 31 for easy replacement of the poster 5.

[0031] Among them, the side end of the elastic retractable device 4 is fixed with a fixing block 8, the bottom end of the support rod 3 is coaxially integrated with a second threaded post 32, the second threaded post 32 is threaded through the fixing block 8, the upper end of the rotating seat 2 is provided with a screw hole 201 for the second threaded post 32 to be threadedly connected, the upper end of the fixed base 1 is provided with an annular groove 101 for the second threaded post 32 to rotate, and the bottom end of the second threaded post 32 is provided with a conical head.

[0032] The above design allows for easy separation of the flexible retractable device 4, poster 5, and support rod 3 from the fixed base 1 and rotating seat 2. When used in outdoor muddy ground, the second threaded post 32 at the bottom of the support rod 3 can be inserted into the ground to fix the roll-up banner, making it more flexible to use and more convenient to carry.

[0033] Considering that the poster 5 is prone to dust or rainwater accumulation on its surface during outdoor display, the poster 5 is preferably made of waterproof material. A flexible sealing ring 10 is fixed at the opening of the elastic retractable device 4. The flexible sealing ring 10 fits snugly on the outside of the poster 5. When storing, the flexible sealing ring 10 can be used to scrape the dust and rainwater on the surface of the poster 5 onto the outside of the elastic retractable device 4, achieving an automatic cleaning effect.

[0034] The working principle of this utility model is as follows: When in use, the user manually pulls the fixing plate 6 upward to pull the poster 5 out of the elastic retractable device 4, so that the fixing plate 6 and the magnetic ring 7 are attracted to each other, so that the fixing plate 6 and the magnetic ring 7 are relatively fixed, thereby achieving a stable display of the poster 5.

[0035] When the wind picks up and a strong wind blows against the poster 5, the wind resistance created by the poster 5 will cause the poster 5 and the rotating base 2 to rotate relative to the fixed base 1. After rotating, the side of the poster 5 faces the windward side, which can reduce wind resistance and thus reduce damage to the poster 5.

[0036] After the wind weakens, the poster 5 and the rotating seat 2 automatically reset under the action of the reset torsion spring 9;

[0037] When the wind is too strong and the poster 5 shakes violently, the fixing plate 6 is pulled by the poster 5 and separates from the magnetic ring 7. Then, the poster 5 is automatically stored in the elastic retractable device 4 under the action of the elastic retractable device 4, so as to avoid further damage to the poster 5.

[0038] 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.
