Description

Technical Field

[0001] The utility model relates to the technical field of publicity boards, in particular to an outdoor publicity board with an external detachable waterproof structure. Background Art

[0002] Outdoor billboards refer to large billboards or advertising signs used to display advertisements, information or promotional content outdoors. These billboards are usually installed in public places, beside roads, on the exterior walls of commercial buildings or other open spaces. They are designed to attract the attention of pedestrians and vehicles passing by and convey specific information or brand image. Due to exposure to outdoor environments, these billboards are usually weather-resistant and can withstand the influence of natural elements such as sunlight and rain.

[0003] A Chinese patent discloses an outdoor advertising billboard (authorization announcement number CN209962662U). The patented technology includes a first support rod, a second support rod and an advertising cloth. The first support rod and the second support rod are both fixedly installed with side support rods by welding. The side support rods are both inclined. An advertising cloth is installed between the first support rod and the second support rod. The first support rod is located on one side of the advertising cloth, and the second support rod is located on the other side of the advertising cloth. The outdoor advertising billboard is provided with a first support rod, a second support rod and a connecting mechanism. By increasing or decreasing the number of connecting mechanisms, the distance between the first support rod and the second support rod can be adjusted according to the length of the advertising cloth. Merchants can better use the advertising billboard for publicity. At the same time, when it needs to be moved, the billboard can be quickly disassembled into four parts: the first support rod, the second support rod, the advertising cloth and the connecting mechanism. It is easy to carry, has a simple structure and a reasonable design, and is therefore easy to promote.

[0004] This patented technology is easy to move and promote when in use, but there are still some shortcomings when in use. The advertising cloth is installed through the first and second support rods. When the advertising cloth needs to be stored after use, the staff needs to manually fold it for storage. It is cumbersome to disassemble and store it and to install and unfold it. Therefore, the technical personnel in this field provide an outdoor billboard with an external detachable waterproof structure to solve the problems raised in the above background technology.
