However, the existing bulletin board design has some shortcomings, especially in the installation and maintenance process, there are usually many inconveniences, which seriously affects its use efficiency and promotion effect.

[0003] The existing bulletin board design usually adopts a fixed structure, such as welding or riveting, although these fixed ways can ensure the stability of the bulletin board, but there are some unavoidable problems in the actual installation process. First of all, the installation process of the traditional bulletin board is complicated and not flexible. In order to ensure the stability of the structure, each part of the bulletin board needs to be accurately matched and fixed by bolts, welding and other methods. Although these processes ensure the firmness of the bulletin board to a certain extent, they lead to complex and time-consuming installation steps.

[0004] Secondly, the traditional bulletin board lacks modular and standardized design, which means that the installation and assembly process of each bulletin board is independent, and usually needs to be customized or adjusted according to the site environment. For example, the fixed frame, panel, support and other parts of the bulletin board are usually customized, which leads to a series of debugging and fixing according to the specific geographical location and use scene during installation. This design not only causes inconvenience in the installation process, but also makes it quite complex to disassemble each part during the later maintenance and replacement, so that maintenance personnel may need to disassemble a large number of parts to complete the maintenance or replacement, thereby increasing the maintenance difficulty and time cost.
