[0002] A smart community refers to a model that integrates various existing service resources in a community by utilizing various intelligent technologies and methods to provide residents with a variety of convenient services such as government affairs, business, entertainment, education, medical care, and mutual assistance. Most communities meet residents' needs in social interaction, entertainment, and learning by regularly holding short-term events, thereby enhancing community cohesion. Traditional smart community bulletin boards play a significant role in promoting corporate culture and disseminating information and announcements about the residential area.

[0003] However, existing technologies have some problems: currently, many bulletin boards are assembled and fixed together by welding, which requires a lot of installation tools during the installation process, making the installation process cumbersome. When it is necessary to disassemble or install the bulletin board after installation, a lot of time and effort are required, resulting in low efficiency and increasing the complexity and cost of the project. It is also very inconvenient for the reuse of bulletin boards. Therefore, we propose a bulletin board that is easy to install and disassemble. Utility Model Content

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] like Figures 1 to 6 As shown in the figure, the present invention provides an easy-to-install and disassemble bulletin board, including a bracket 1, a support leg 2 on the bracket 1, two brackets 1, a bulletin board 3 between the two brackets 1, the support leg 2 is configured to cooperate with the bracket 1 and the support leg 2 and the bracket 1 can extend and retract together, a canopy 4 is provided on the bracket 1, a limit component 5 is provided between the bracket 1 and the bulletin board 3, a base 23 is fixedly connected to the lower end of the support leg 2, and an anti-slip pad 24 is provided on the base 23.

[0024] Furthermore, the design of retractable support legs 2, which work in conjunction with the bracket 1, not only ensures the stability of the bulletin board but also greatly facilitates the installation and disassembly process, saving time and labor costs. Meanwhile, the canopy 4 on the bracket 1 effectively protects the advertising content from inclement weather, while the limiting component 5 further enhances the secure fixation of the advertising board 3. In addition, the anti-slip pads 24 on the base 23 effectively prevent the bulletin board from sliding during use, improving overall safety and stability.

[0025] Specifically, the canopy 4 is provided with a connecting block 41, the support 1 is provided with a connecting plate 11, the connecting plate 11 is provided with an insert plate 12, the connecting block 41 is provided with a clearance groove 42, the clearance groove 42 is provided with a slot 43, the clearance groove 42 is provided with a corresponding connection plate 11, the slot 43 is provided with a corresponding insert plate 12, the support 1 is provided with a sliding groove 13, and the advertising board 3 is provided with lifting lugs 31 on both sides, the sliding groove 13 is provided with a corresponding lifting lug 31.

[0026] Furthermore, the canopy 4 is connected to the connecting plate 11 on the bracket 1 via the connecting block 41. The corresponding arrangement of the insert plate 12 and the slot 43 makes the installation process simpler and faster, while ensuring the stability of the structure. The sliding groove 13 on the bracket 1 corresponds to the lifting lugs 31 on both sides of the advertising board 3, which not only facilitates the quick installation and disassembly of the advertising board 3, but also provides flexible adjustment space to adapt to the needs of different scenarios.

[0027] Specifically, the limiting component 5 includes a limiting pin 51, a limiting hole 18 is provided on the bracket 1, the limiting pin 51 is inserted into the limiting hole 18, a limiting ring 52 is sleeved on the limiting pin 51, the limiting ring 52 is slidably connected to the limiting hole 18, a spring 53 is provided in the limiting hole 18, one end of the spring 53 contacts the limiting hole 18, and the other end of the spring 53 contacts the limiting ring 52.

[0028] Furthermore, the advertisement board 3 and the bracket 1 are firmly fixed by inserting the limiting pin 51 into the upper limit hole 18 of the bracket 1. The sliding connection between the limiting ring 52 on the limiting pin 51 and the limiting hole 18, as well as the setting of the spring 53, not only enhance the stability of the structure, but also make it easy for operators to insert and remove the limiting pin 51 during installation or disassembly.

[0029] Furthermore, during use, pulling the limit pin 51 disengages it from the lifting lug 31, releasing the restriction on the advertising board 3. The limit pin 51 is then released by compressing the spring 53 via the limit ring 52. After the limit pin 51 is released, it automatically resets via the spring 53.

[0030] Specifically, a connecting rod 19 is provided between the two brackets 1, and the connecting rod 19 is threadedly connected to the bracket 1.

[0031] Furthermore, by incorporating connecting rod 19, the overall structural strength of the bulletin board is enhanced, making it more stable when subjected to external forces such as wind and human contact, and less prone to tipping over or deformation. Simultaneously, the threaded connection facilitates installation and disassembly, allowing operators to fix and adjust connecting rod 19 without complex tools, improving work efficiency and facilitating subsequent maintenance and replacement, thus ensuring the long-term stable use of the bulletin board.

[0032] Specifically, a cavity 14 is formed inside the support 1, and a gear 15 is installed inside the cavity 14. A knob 16 is rotatably connected to the support 1, and the knob 16 is fixedly connected to the gear 15. A slider 21 is installed on the support leg 2, and a rack 22 is installed on the slider 21. The gear 15 meshes with the rack 22. A wrap angle 17 is installed on the support 1, and the wrap angle 17 is correspondingly set with the slider 21.

[0033] Furthermore, by rotating the knob 16, the gear 15 drives the rack 22 to move, which in turn drives the slider 21 to slide on the bracket 1, thereby adjusting the height of the bulletin board. The corner bracket 17 not only enhances the structural strength of the bracket 1, but also ensures the stability and safety of the slider 21 during movement, preventing the support leg 2 from overtraveling when sliding. This not only improves the applicability and flexibility of the bulletin board, but also simplifies the installation and adjustment process.

[0034] Working principle: During installation, first position the bracket 1, the canopy 4, the advertising board 3, and the connecting rod 19. Then, while inserting the connecting plate 11 and the connecting block 41, connect the advertising board 3 and the connecting rod 19 to the advertising board 3 to achieve mutual fixation between multiple sets of structures. This not only makes the operation simple and quick, but also ensures a stable structure, improving installation efficiency and safety. This modular design also facilitates subsequent maintenance and upgrades, providing a guarantee for the long-term stable operation of the advertising board and effectively extending its service life.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
