Description

Technical Field

[0001] This utility model relates to the field of billboards, and more specifically, to an outdoor billboard with a double-sided structure. Background Technology

[0002] As a mainstream outdoor advertising medium, billboards primarily function to accurately convey various information such as commercial promotions and public service announcements to the public. Leveraging their intuitive visual presentation, they serve as a crucial bridge connecting brands and consumers, possessing both commercial value and communicative attributes. To maximize information coverage, billboards are typically located in densely populated areas, including bus stops, shop entrances, intersections, commercial districts, main roadsides, entrances to large residential communities, and highway service areas. They capitalize on the high frequency of pedestrian and vehicle traffic to increase the exposure of advertising content. The adoption of a double-sided structural design is a key means of optimizing space utilization. It allows for two-way information display within limited installation space, adapting to different viewing angles, without requiring additional installation space, thus reducing construction and maintenance costs. Therefore, it has become the mainstream form of outdoor billboards.

[0003] In complex outdoor environments, wind impact is a core challenge affecting the stability of billboards, and related technologies are constantly being iterated and optimized. For example, Chinese utility model patent CN221446769U addresses wind resistance with its design improvements. This patent utilizes a sliding structure with a slider and guide rail, allowing for sliding displacement under wind force. This buffers the impact of the wind, effectively reducing the direct effect of strong winds on the billboard structure. Simultaneously, a buffer spring releases elastic potential energy during lulls in the wind, causing the slid-out billboard to reset and quickly return to its initial state to withstand subsequent strong wind impacts. Compared to traditional fixed-structure billboards that are easily damaged by strong winds, this design significantly improves wind resistance and safety, making it suitable for outdoor installations in windy areas.

[0004] However, this patent still has obvious technical shortcomings: the buffer spring has a fixed extension limit. When the wind is extremely strong and the spring is compressed to its limit, its buffering function will completely fail. At this time, the entire billboard must directly withstand the wind load. The instantaneous impact force generated by the strong wind will be concentrated on the connection point between the billboard and the support. Long-term repeated stress can easily lead to loose bolts and cracked welds at the connection points, and even cause safety accidents such as support breakage and billboard falling. This not only affects the service life of the equipment, but also poses a great outdoor safety hazard. In view of the shortcomings of the existing technology, and combined with the practical advantages of the double-sided structure, we propose an outdoor billboard with a double-sided structure, which aims to balance information display efficiency and wind resistance stability, and make up for the defects of the existing design. Utility Model Content

[0005] The purpose of this utility model is to solve the problems currently raised.

[0006] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides an outdoor billboard with a double-sided structure, including a mounting base. Two mounting plates are fixedly connected to the front surface of the mounting base. A connecting shaft is fixedly connected to the adjacent side surface of each of the two mounting plates. A connecting sleeve is rotatably fitted onto the outer surface of the two connecting shafts. A double-sided billboard is fixedly connected to the connecting sleeve. Relief grooves are formed on both the upper and lower surfaces of the connecting sleeve. Torsion springs are fixedly connected to the inner wall of the relief grooves. The ends of the two torsion springs that are far apart from each other are fixedly connected to the two mounting plates respectively. Two sets of buffer pads are fixedly connected to the front surface of the mounting base. The two sets of buffer pads are respectively set on the left and right sides of the double-sided billboard. Two sets of sliding grooves are formed on the front surface of the mounting base, with two sliding grooves in each set. Protective components are provided inside the sliding grooves.

[0007] As a preferred technical solution of this application, the protective component includes a guide rod, which is fixedly connected to the inner wall of the sliding groove. Two guide plates are provided on the front side of the mounting base. Both guide plates are configured in a ∠ shape and are mirror images of each other.

[0008] As a preferred technical solution of this application, a sliding block is fixedly connected to the rear surface of the guide plate, and the sliding block is slidably connected inside the sliding groove.

[0009] As a preferred technical solution of this application, the sliding block is slidably connected to the guide rod.

[0010] As a preferred technical solution of this application, a return spring is fixedly connected to the sliding block.

[0012] As a preferred technical solution of this application, the end of the cable is fixedly connected to the double-sided billboard, and a cable hole is opened on the rear surface of the connecting sleeve.

[0013] As a preferred technical solution of this application, mounting ears are fixedly connected to both the upper and lower surfaces of the mounting base, and fixing bolts are provided on the mounting ears.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. The rotatable design of the double-sided billboard can be used to make the billboard flush with the mounting base when the wind is strong, reducing the wind-exposed area and thus greatly reducing the stress on the connecting shaft, preventing it from breaking. At the same time, the design of the buffer pad can prevent the double-sided billboard from being damaged by collision due to excessive folding, effectively ensuring the safety of the double-sided billboard itself. 2. The design of the deflector plate can guide the wind direction after the double-sided billboard is folded, preventing the wind from blowing directly to the sides of the double-sided billboard and further reducing the pressure on the connecting shaft. At the same time, the design of the deflector plate moving on its own as the double-sided billboard is folded can prevent the deflector plate itself from becoming loose due to wind force after the two deflector plates and the double-sided billboard are integrated into a whole.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example 1

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 An outdoor billboard with a double-sided structure includes a mounting base 1. Two mounting plates 2 are fixedly connected to the front surface of the mounting base 1. Connecting shafts 3 are fixedly connected to the adjacent surfaces of the two mounting plates 2. Connecting sleeves 4 are rotatably fitted onto the outer surfaces of the two connecting shafts 3. A double-sided billboard 5 is fixedly connected to the connecting sleeves 4. Relief grooves 6 are formed on both the upper and lower surfaces of the connecting sleeves 4. Torsion springs 7 are fixedly connected to the inner walls of the relief grooves 6. The ends of the two torsion springs 7 that are far apart from each other are fixedly connected to the two mounting plates 2 respectively. Two sets of buffer pads 8 are fixedly connected to the front surface of the mounting base 1. Two sets of buffer pads 8 are respectively set on the left and right sides of the double-sided billboard 5. The front surface of the mounting base 1 is provided with two sets of sliding grooves 9. The sliding grooves 9 are equipped with protective components. With the help of the rotatable design of the double-sided billboard 5, the double-sided billboard 5 can be made flush with the mounting base 1 when the wind is strong, reducing the wind-exposed area and thus greatly reducing the stress on the connecting shaft 3, preventing it from breaking. At the same time, the design of the buffer pads 8 can prevent the double-sided billboard 5 from being damaged by collision due to excessive folding, effectively ensuring the safety of the double-sided billboard 5 itself. Example 2

[0022] The outdoor billboard with a double-sided structure provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the protective assembly includes a guide rod 10, which is fixedly connected to the inner wall of the sliding groove 9. Two guide plates 11 are provided on the front side of the mounting base 1, both of which are ∠-shaped and mirror-image. A sliding block 12 is fixedly connected to the rear surface of the guide plate 11, and the sliding block 12 is slidably connected inside the sliding groove 9. The sliding block 12 is slidably connected to the guide rod 10. A return spring 13 is fixedly connected to the sliding block 12, and its end is fixedly connected to the inner wall of the sliding groove 9. A cable 14 is fixedly connected to the guide plate 11, and its end is connected to... The double-sided billboard 5 is fixedly connected. The rear surface of the connecting sleeve 4 is provided with a cable hole 15. The upper and lower surfaces of the mounting base 1 are fixedly connected with mounting ears 16. The mounting ears 16 are provided with fixing bolts 17. Through the design of the guide plate 11, the wind direction can be guided after the double-sided billboard 5 is folded, so as to avoid the wind blowing directly to the side of the double-sided billboard 5 and further reduce the pressure on the connecting shaft 3. At the same time, the guide plate 11 can move on its own as the double-sided billboard 5 is folded. After the two guide plates 11 and the double-sided billboard 5 are integrated into a whole, the guide plate 11 itself can be prevented from becoming loose due to the wind force.

[0023] The power supply line for the double-sided billboard 5 can pass through the cable hole 15, and sufficient space must be reserved for the wire to prevent it from breaking. The usage process of the double-sided outdoor billboard provided by this utility model is as follows: In windy weather, if the wind force exceeds the elastic force of the two sets of torsion springs 7 and the return spring 13, it will cause the double-sided billboard 5 to rotate. During rotation, the billboard 5 will rotate around the connecting shaft 3 via the connecting sleeve 4, compressing the two sets of torsion springs 7. Simultaneously, during the rotation of the billboard 5, one side of the cable 14 will loosen, while the other side will tighten. The guide plate 11 on the loosened side remains in position, while the guide plate 11 on the other side will move due to the pull of the cable 14. During the movement of the guide plate 11, it can be limited by the sliding groove 9 in conjunction with the guide rod 10. The double-sided billboard 5 controls its own movement trajectory, and during the movement, it will compress the return spring 13. After the double-sided billboard 5 is completely folded, it is parallel to the mounting base 1. At this time, the double-sided billboard 5 is in contact with the buffer pad 8. As one side of the guide plate 11 is pulled close to the double-sided billboard 5, both sides of the double-sided billboard 5 are protected by the guide plate 11. The slope of the guide plate 11 can guide the wind direction and prevent the wind force from directly acting on the double-sided billboard 5, reducing the pressure on the connecting shaft 3. At the same time, when the wind force weakens, the double-sided billboard 5 and the guide plate 11 will automatically return to their original positions under the action of the torsion spring 7 and the return spring 13.
