[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a technical solution: a prefabricated children's aesthetic education bulletin board, including a bulletin board 2 and columns 1 on the left and right sides of the bulletin board 2. Each adjacent side wall of the two columns 1 has a second through hole 102. Connecting columns 201 are welded to the left and right side walls of the bulletin board 2, and the connecting columns 201 are inserted into the cavities of the second through holes 102 to facilitate assembly between the bulletin board 2 and the columns 1. A plug-in block 103 is welded to the bottom wall of the column 1, a third through hole 104 is formed on the surface of the plug-in block 103, a support assembly is connected to the bottom of the column 1, and an expansion assembly is provided inside the bulletin board 2.

[0022] The support assembly includes a base 4 located at the bottom of the column 1, a slot 401 formed in the top wall of the base 4, and a third through hole 104 inserted into the cavity of the slot 401. The base 4 has a positioning cavity 402 located outside the slot 401, with the side furthest from the center of the two slot 401 cavities being the outer side of the slot 401. A positioning rod 15 is disposed within the cavity of the positioning cavity 402, with its inner end extending through the cavity wall of the positioning cavity 402 and into the cavity of the slot 401. The end closest to the slot 401 is the inner end of the positioning rod 15. The rod body of the positioning rod 15 is inserted into the cavity of the third through hole 104. The other end of the positioning rod 15 moves through the other side wall of the positioning cavity 402. The reset plate 16 and the spring 17 are disposed in the cavity of the positioning cavity 402. The reset plate 16 is welded to the surface of the rod body of the positioning rod 15, and the spring 17 is sleeved on the surface of the rod body of the positioning rod 15. The spring 17 is located on the side of the reset plate 16 away from the slot 401. The purpose is to make the reset plate 16 squeeze the spring 17 when the positioning rod 15 is pulled out from the third through hole 104, so that the positioning rod 15 can be automatically reset under the action of the spring 17 after the positioning rod 15 is released. The expansion components include a storage cavity 202 inside the advertising board 2. Guide rods 11 are welded between the upper and lower side walls of the left and right sides of the storage cavity 202. Slider 12 is slidably connected to the surface of the guide rods 11. The expansion plate 9 is set in the inner cavity of the storage cavity 202. The left and right side walls of the expansion plate 9 are welded to the walls of the sliders 12 on the left and right sides, respectively. A handle 10 is welded to the bottom wall of the expansion plate 9. A rotating column 13 is threaded to the left bottom wall of the advertising board 2. A limiting plate 14 is welded... On the surface of the rotating column 13, horizontal blocks 6 are welded to the adjacent side walls at the bottom of the two columns 1. Clips 7 are adhered to the top wall of the horizontal blocks 6. The clips 7 are made of plastic, giving them deformability, allowing the connecting rod 8 to be easily pressed into the annular cavity of the clip 7. The connecting rod 8 is movably connected between adjacent clips 7, enabling assembly between the connecting rod 8 and the clip 7. Limit heads 801 are welded to both ends of the connecting rod 8 to prevent it from detaching from the clip 7. Universal wheels 5 are installed on the front and rear bottom walls of the column 1. A first through hole 101 is opened on the top wall of the column 1. The canopy 3 is located on the top of the advertising board 2. Insert rods 301 are welded to the bottom walls on both sides of the canopy 3, and these rods 301 are movably inserted into the cavity of the first through hole 101.

[0023] By opening a second through hole 102 on the side wall of the column 1, connecting columns 201 are fixed to the two side walls of the advertising board 2, allowing the connecting columns 201 to be inserted into or removed from the second through hole 102. This facilitates quick assembly and disassembly between the column 1 and the advertising board 2. Furthermore, by providing a plug-in block 103 on the bottom wall of the column 1, and opening a third through hole 104 on the surface of the plug-in block 103, and by opening a slot 401 on the surface of the base 4, the plug-in block 103 can be inserted into or removed from the slot 401. This also allows for easy disassembly of the column 1 and the base when disassembly is required. At time 4, simply pull the positioning rod 15 to remove it from the third through hole 104 on the surface of the plug block 103. During this process, the reset plate 16 will compress the spring 17. The purpose is to facilitate automatic reset after the positioning rod 15 is released. After the positioning rod 15 is removed, the plug block 103 can be taken out from the slot 401, thereby completing the quick assembly and disassembly between the column 1 and the base 4. This greatly facilitates the transportation of the bulletin board. Furthermore, the detachable connection between the plug rod 301 and the first through hole 101 facilitates the assembly connection between the column 1 and the canopy 3. By creating a storage cavity 202 in the advertising board 2 and setting an extension plate 9 in the storage cavity 202, when the advertising board 2 is insufficient, the limiting plate 14 can be moved to one side so that it no longer supports the extension plate 9, allowing the extension plate 9 to slide out of the storage cavity 202. During this process, the slider 12 will move downward along the guide rod 11. When the extension plate 9 is not needed, it can be stored back into the storage cavity 202, which is very convenient. By rotating one end of the limiting plate 14 to directly below the extension plate 9, it can be prevented from sliding out of the storage cavity 202, thus avoiding the situation where only one advertising board 2 is used for display.
