Description

Technical Field

[0001] The utility model relates to the technical field of billboards, in particular to an outdoor billboard with a long service life. Background Technique

[0002] Outdoor billboards, as an indispensable information dissemination medium in urban and rural environments, are widely used in various fields such as advertising, announcements, and cultural exhibitions. They not only carry rich information content but also, with their eye-catching appearance and location, become an important tool to attract public attention. However, with the increasing usage frequency and continuous environmental changes, outdoor billboards also face many challenges.

[0003] In the prior art, firstly, from the perspective of replacing the promotional content, most traditional outdoor billboards rely on manual operations such as screw fixation and disassembly. This process is not only time-consuming and laborious but also prone to damage or improper installation. Especially in situations where rapid response to market changes or emergencies is required, the replacement efficiency of traditional billboards is particularly insufficient. In addition, frequent manual operations increase the maintenance cost and reduce the overall economic benefits. Secondly, the environment where outdoor billboards are located is complex and changeable. Being exposed to sunlight, wind, and rain for a long time, it is easy to accumulate pollutants such as dust and dirt. These pollutants not only affect the visual effect of the billboard but may also damage the structure of the billboard and shorten its service life. Therefore, regular cleaning and maintenance of outdoor billboards are essential. However, the traditional manual cleaning method is not only inefficient but also difficult to achieve timely cleaning effects. In response to the above problems, although there are already some outdoor billboard products with a relatively high degree of automation on the market, most of them have disadvantages such as complex structure, high cost, and difficult maintenance. Therefore, how to design an outdoor billboard that can efficiently replace the promotional content, automatically clean the surface, has a moderate cost, and is easy to maintain has become a technical problem that needs to be solved currently. Against this background, the utility model is committed to providing an innovative solution. By optimizing the design of the transmission mechanism and the cleaning mechanism, it realizes the alternating replacement of the billboard while cleaning the transparent glass. This design not only simplifies the operation process, improves the replacement efficiency, but also reduces the maintenance cost and extends the service life of the billboard. At the same time, its simple structure and reasonable layout are also convenient for users to carry out daily management and maintenance, providing a broader space for the application of outdoor billboards. For this reason, we propose an outdoor billboard with a long service life to solve the above problems. Content of the Utility Model

[0026] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides an outdoor billboard with a long service life through improvement. The technical solution of the present utility model is as follows:

[0028] As Figure 1 - Figure 8 shown, an outdoor billboard with a long service life includes a base 1. A metal mounting plate 2 is fixedly connected to the upper surface of the base 1. A rain shield 3 is fixedly connected to the upper surface of the metal mounting plate 2. Two symmetrically arranged installation grooves 4 are formed in the side wall of the metal mounting plate 2. The two installation grooves 4 communicate with each other. A rotating shaft 6 is rotatably connected to the inner wall of the installation groove 4. A gear 7 is fixedly connected to the surface of the rotating shaft 6. A billboard 8 is placed in the installation groove 4. A rack 9 is fixedly connected to the lower surface of the billboard 8. The two racks 9 are meshed with the gear 7. A polygonal groove 10 is formed at the lower end of the rotating shaft 6. A polygonal limiting groove 11 communicating with the polygonal groove 10 is formed in the lower surface of the metal mounting plate 2. A polygonal limiting post 20 is arranged in the polygonal groove 10 and the polygonal limiting groove 11. The polygonal limiting post 20 matches the polygonal groove 10 and the polygonal limiting groove 11. A cleaning mechanism is arranged on the metal mounting plate 2.

[0029] Further, the cleaning mechanism includes two sliding grooves 12 which are opened on both sides of the metal mounting plate 2. The two sliding grooves 12 are communicated with the mounting groove 4. Compression springs 13 are fixedly connected to the inner walls of the two sliding grooves 12. The other ends of the two compression springs 13 are fixedly connected with sliders 14. One end of the slider 14 is slidably connected to the inner wall of the sliding groove 12, and the other end of the slider 14 extends into the mounting groove 4 and abuts against the rack 9. Cleaning brushes 15 are arranged on both sides of the metal mounting plate 2. The lower ends of the cleaning brushes 15 are fixedly connected to the upper surfaces of the sliders 14. The side walls of the sliders 14 abut against the side walls of the rack 9. A connecting block 21 is fixedly connected to the upper end of the cleaning brush 15. A roller 22 is rotatably connected to the inner wall of the connecting block 21. The surface of the roller 22 abuts against the side wall of the metal mounting plate 2. By providing the roller 22, during use, the frictional resistance during the movement of the cleaning brush 15 is reduced, making the cleaning process smoother, and at the same time avoiding scratches or damages caused by direct contact.

[0030] Further, observation ports 5 are opened on the front and rear sides of the metal mounting plate 2. Transparent glasses 16 are arranged in the observation ports 5. The transparent glasses 16 can allow light and sight to pass through freely, and at the same time can more effectively prevent external factors such as dust and sundries from entering the inside of the observation ports 5.

[0031] Further, the material between the two mounting grooves 4 is transparent acrylic material. The transparent acrylic material has a high light transmittance, so that the front and back surfaces of the promotional board 8 can be displayed through the observation ports 5.

[0032] Further, placing grooves 17 matching the two mounting grooves 4 are opened on the side wall of the metal mounting plate 2. Baffles 18 are placed in the placing grooves 17. By providing the baffles 18, the mounting grooves 4 and the internal promotional board 8 can be blocked, playing a certain dust-proof role.

[0033] Further, an annular magnet strip 19 is embedded in the side wall of the baffle 18, and the magnet strip 19 is magnetically attracted to the inner wall of the placing groove 17. The magnetic attraction between the magnet strip 19 and the inner wall of the placing groove 17 can firmly fix the baffle 18 in the placing groove 17, thereby enhancing the stability of the installation.

[0034] Further, the polygonal limiting post 20 has magnetism, and the polygonal limiting post 20 is magnetically attracted to the lower surface of the metal mounting plate 2. The magnetic attraction makes the polygonal limiting post 20 firmly fixed on the metal mounting plate 2 and not easy to loosen or fall off.

[0035] Working principle: When in use, by setting the gear 7 and the rack 9, when it is necessary to replace the promotional content, first, the polygonal limit posts 20 in the polygonal groove 10 and the polygonal limit groove 11 can be pulled out to release the limit of the rotating shaft 6. Then, the new promotional board 8 is placed in another idle installation groove 4 and slowly pushed in. The rack 9 fixedly connected to the promotional board 8 acts on the gear 7 to make the gear 7 rotate. At the same time, through the meshing action of the gear 7 and the rack 9, the promotional board 8 already in the installation groove 4 moves axially to leave the installation groove 4, completing the replacement of the promotional board 8. The material between the two installation grooves 4 is set as transparent acrylic, so that both the front and back of the promotional board 8 can be displayed through the observation port 5. The compression spring 13 is in a stretched state in its natural state. The slider 14 and the cleaning brush 15 are near the entrance of the installation groove 4. When the promotional board 8 enters the installation groove 4, the rack 9 fixedly connected to the promotional board 8 moves accordingly. Then the rack 9 will touch the slider 14 and continue to move inward. The slider 14 compresses the compression spring 13 and drives the cleaning brush 15 to move, achieving the effect of cleaning the transparent glass 16. When the promotional board 8 leaves the installation groove 4, due to the resilience of the compression spring 13, the slider 14 drives the cleaning brush 15 to reset along with the movement of the promotional board 8. The reset process achieves the effect of cleaning the transparent glass 16. Then, the polygonal limit post 20 is inserted into the polygonal limit groove 11 and the polygonal groove 10 to limit the rotating shaft 6 so that it cannot rotate, thereby ensuring that the gear 7 will not rotate and the promotional board 8 cannot move randomly. Finally, the baffle 18 is placed in the placement groove 17, and through the magnetic attraction between the magnetic strip 19 and the inner wall of the placement groove 17, the baffle 18 can be firmly fixed in the placement groove 17 to cover the entrance of the installation groove 4.

[0036] The above description enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
