[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-7 A modular bulletin board includes two bulletin boards 1. Each bulletin board 1 has a base 2 at its bottom, and two telescopic columns 3 are slidably mounted on the top of each base 2. A connecting ring 4 is fixedly mounted on the back of each bulletin board 1, and the connecting ring 4 is rotatably connected to the top of the telescopic columns 3. A connecting component is provided between the two bulletin boards 1. During use, both bulletin boards 1 are rectangular in shape. The connection state of the two bulletin boards 1 is twofold: in one state, the two short sides of the two bulletin boards 1 are connected, maximizing the length of the device and making it suitable for narrow corridors; in the second state, the long sides of the two bulletin boards 1 are connected, shortening the overall length of the device and utilizing the top vertical space for advertising and display. Simultaneously, the telescopic columns 3 can be retracted to reduce the overall height of the bulletin board 1. The two combined states of the two bulletin boards 1 allow for modular combination to meet the needs of different venues.

[0026] As a preferred embodiment, the connecting component includes multiple snap-fit ​​posts 5, which are respectively fixedly installed on two adjacent sides of the two bulletin boards 1. The snap-fit ​​posts 5 on the corresponding sides of the two bulletin boards 1 are staggered. Multiple snap-fit ​​holes 6 are provided on the sides of the two bulletin boards 1, and the snap-fit ​​holes 6 are located between the two snap-fit ​​posts 5. The snap-fit ​​post 5 on one side of the bulletin board 1 corresponds to the snap-fit ​​hole 6 on the other side of the bulletin board 1. When assembling the two bulletin boards 1, the snap-fit ​​post 5 is inserted into the corresponding snap-fit ​​hole 6 to complete the assembly.

[0027] As a preferred technical solution in this embodiment, the top of the base 2 is provided with a sliding groove 7, and the two telescopic columns 3 are slidably installed at both ends of the sliding groove 7. A ball screw 8 is rotatably installed inside the sliding groove 7. The two ends of the ball screw 8 have opposite thread directions, and the two ends of the ball screw 8 are threadedly connected to the two telescopic columns 3 respectively. A rotating handle 9 is rotatably connected to the side wall of the base 2, and the rotating handle 9 is fixedly connected to one end of the ball screw 8. When the two bulletin boards 1 are switched, the rotating handle 9 drives the ball screw 8 to rotate, which drives the two telescopic columns 3 to move away from or towards each other through the threaded transmission.

[0028] As a preferred technical solution in this embodiment, the telescopic column 3 is slidably mounted with four locking posts 10 on its top four sides. A spring 11 is fixedly connected between the multiple locking posts 10 and the telescopic column 3. Multiple slots 12 are opened on the inner wall of the connecting ring 4, and the locking posts 10 are adapted to the slots 12. The end of the locking post 10 inside the slot 12 is set as a ball head. In actual use, the bulletin board 1 is simply fixed by locking the locking post 10 with the slot 12. After receiving external force, the locking post 10 is compressed out of the slot 12, so that the bulletin board 1 can rotate. When the two bulletin boards 1 are separated, the stability of the two bulletin boards 1 can also be guaranteed.

[0029] As a preferred technical solution in this embodiment, a handle 13 is fixedly installed at the bottom of the end of the bulletin board 1 away from the connecting ring 4. The reason for installing the handle 13 at the bottom of the end away from the connecting ring 4 is that, after the bulletin board 1 is rotated, the handle 13 is located at the top of the side, and the position of the handle 13 is convenient for gripping in both combined states. In addition, the bulletin board 1 is rectangular in shape and rotates with the center of the connecting ring 4 as the origin. Installing the handle 13 at the bottom of the end away from the connecting ring 4 can make the entire bulletin board 1 a lever, making it easier to rotate the bulletin board 1.

[0030] As a preferred technical solution of this embodiment, a sealing strip 14 is provided on the long side of the top of the bulletin board 1, and a magnet 15 is installed on the side wall of the sealing strip 14. The sealing strip 14 is engaged with a plurality of the snap-fit ​​posts 5. When the short sides of the two bulletin boards 1 are connected, the snap-fit ​​posts 5 and snap-fit ​​holes 6 on the top long side are exposed and protected by the sealing strip 14. By providing the magnet 15 on the sealing strip 14, it is easy to magnetically attach the sealing strip 14 to the back of the bulletin board 1, and it is easy to store the sealing strip 14.

[0031] As a preferred technical solution in this embodiment, rollers 16 are fixedly installed at the four corners of the bottom of the base 2; the rollers 16 facilitate simple movement of the device.
