Technical Field

[0001] This utility model relates to a foldable billboard that is easy to transport, and belongs to the field of billboard technology. Background Technology

[0002] Billboards refer to all outdoor media that convey advertising information. The size of the media depends on the actual environment and can be produced by hand-drawing, computer-generated, or printed on paper. The materials used for billboards are generally welded from square tubing, angle steel, etc. Other materials include 3D panels, lightbox fabric, vacuum forming, automotive paint, snap-on panels, and aluminum composite panels. For example, when a large event is held in a certain location, many billboards are usually set up around the perimeter.

[0003] However, most existing billboards are not foldable, making them troublesome to move and costly to transport. Once the advertisement is fixed, it is not easy to remove, making it difficult to replace.

[0004] This utility model proposes a new solution to the above problems. Utility Model Content

[0005] The main purpose of this utility model is to solve the problems of cumbersome transfer and high transportation costs, as well as the difficulty in removing and replacing advertisements once they are fixed. Therefore, it provides a foldable advertising board that is easy to transport.

[0027] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0028] like Figures 1-8 As shown, this embodiment provides a foldable advertising board that is easy to transport, including a base 1 and an upper frame 2. A hinge 3 is provided on the back of the base 1, and the base 1 is rotatably connected to the upper frame 2 via the hinge 3. Mounting grooves 4 are provided at the bottom corner of the base 1 and the top corner of the upper frame 2. Screw holes 5 are provided on the inner wall of the mounting grooves 4, and elastic blocks 6 are provided on the inner wall of the mounting grooves 4. Through holes 7 are provided on the surface of the elastic blocks 6, and fixing areas 8 are provided on the elastic blocks 6. Advertising signs are provided on the front of both the base 1 and the upper frame 2. When installing the elastic block 6 in the groove 14, the elastic block 6 is inserted into the mounting groove 4, and then the bolt is inserted into the through hole 7 and tightened in the screw hole 5. In the normal state, the elastic block 6 presses the fixing area 8 against the inner wall of the advertising groove 14, lifts the fixing area 8 upward, so that the elastic block 6 undergoes elastic deformation, thereby generating elastic force, placing the corner of the advertisement below the fixing area 8, and then releasing the fixing area 8. Under the elastic force of the elastic block 6, the fixing area 8 fixes the corner of the advertisement to the inner wall of the advertising groove 14.

[0029] In this embodiment, as Figure 1 , Figure 4 and Figure 5As shown, the inner wall of the advertising slot 14 is fixedly connected to a limiting slot 9. The limiting slot 9 is cut in the middle, and the two segments of the limiting slot 9 are distributed on the base 1 and the upper frame 2. The inner wall of the limiting slot 9 is fixedly connected to a damping rotating shaft 10. The surface of the damping rotating shaft 10 is fixedly connected to a limiting plate 11. The lower surface of the upper frame 2 is fixedly connected to a first wear-resistant pad 13, and the upper surface of the base 1 is fixedly connected to a second wear-resistant pad 12. To unfold the billboard, unfold the base 1 and the upper frame 2, and then rotate the limiting plate 11 so that the limiting plate 11 is fully inserted into the limiting slot 9, making it difficult for the base 1 and the upper frame 2 to close again after unfolding. Conversely, remove the limiting plate 11 from the limiting slot 9, rotate the upper frame 2, and fold the base 1 and the upper frame 2 to facilitate the transfer of the billboard.

[0030] In this embodiment, as Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, a sleeve 15 is fixedly connected to the lower surface of the base 1. The sleeves 15 are symmetrically distributed, and positioning holes 16 are opened on the surface of the sleeves 15. A support rod 17 is slidably connected to the inner wall of the sleeve 15. The surface of the support rod 17 is provided with mating holes 18, which are evenly distributed. A base plate 19 is fixedly connected to the lower surface of the support rod 17. A baffle 20 is fixedly connected to one end of the support rod 17. The inner wall of the sleeve 15 is slidably connected to the baffle 20. A soft band 21 is fixedly connected to the surface of the sleeve 15. A limiting rod 22 is fixedly connected to the surface of the soft band 21. A slot 23 is opened on the surface of the limiting rod 22. The shape of the slot 23 is similar to that of the base 1. With the mating hole 18 fitted, the base plate 19 is placed on the ground. The base plate 19 prevents the billboard from tipping over. Then, the base 1 and the upper frame 2 are raised and their heights are adjusted. After adjustment, the positioning hole 16 is aligned with the nearest mating hole 18. Then, the limiting rod 22 is inserted into the positioning hole 16, so that the slot 23 is aligned with the position of the mating hole 18. Then, the base 1 and the upper frame 2 are released. Under the action of gravity, the sleeve 15 and the support rod 17 slide, so that the mating hole 18 is inserted into the slot 23, so that the position of the support rod 17 and the sleeve 15 is fixed, and the limiting rod 22 is not easy to disengage from the positioning hole 16.

[0031] In this embodiment, as Figures 1-8 As shown in the figure, the working principle of the foldable billboard that is easy to transport provided in this embodiment is as follows:

[0032] Unfold the base 1 and the upper frame 2, then rotate the limiting plate 11 so that it is fully inserted into the limiting groove 9, making it difficult for the base 1 and the upper frame 2 to close again after unfolding. Lift the fixing area 8 upwards, causing the elastic block 6 to undergo elastic deformation, thereby generating elastic force. Place the corner of the advertisement below the fixing area 8, and then release the fixing area 8. Under the elastic force of the elastic block 6, the fixing area 8 fixes the corner of the advertisement to the inner wall of the advertisement groove 14. Adjust the height of the base 1 and the upper frame 2. After adjustment, align the positioning hole 16 with the nearest mating hole 18. Then insert the limiting rod 22 into the positioning hole 16, so that the slot 23 matches the position of the mating hole 18. Then release the base 1 and the upper frame 2. Under the action of gravity, the sleeve 15 and the support rod 17 slide, so that the mating hole 18 is inserted into the slot 23, thus fixing the position of the support rod 17 and the sleeve 15.

[0033] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
