[0014] The base is equipped with casters at all four corners, and the front of the display board is rotatably connected to a hinge, with a transparent plate rotatably connected to the outer wall of the hinge.

[0015] The above technical solution protects the posters inside using a transparent panel while allowing for easy viewing.

[0016] As a further description of the above technical solution:

[0017] An adjustment frame is fixedly connected to the top of the base, and a reinforcing bolt is threaded onto the outer wall of the adjustment frame.

[0018] The above technical solution allows for height adjustment of the device by using an adjustment frame in conjunction with reinforcing bolts, making it more practical.

[0019] As a further description of the above technical solution:

[0020] The outer walls of the adjustment frame are all fixedly connected with reinforcing plates, and the bottoms of the multiple reinforcing plates are all fixedly connected to the top of the base.

[0021] The above technical solution connects the adjustment frame and the base with a reinforcing plate, ensuring the stability of the adjustment frame.

[0022] As a further description of the above technical solution:

[0023] A handle is fixedly connected to the front side of the transparent plate, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0024] The above technical solution involves installing a handle on the front of the transparent panel, along with an anti-slip sleeve, to facilitate opening the panel and replace the internal posters.

[0025] As a further description of the above technical solution:

[0026] The top left and right sides of the notice board are fixedly connected to fixed columns, and the top of each of the two fixed columns is fixedly connected to a shielding plate.

[0027] The above technical solution allows the shielding plate to block light and rain, further improving the service life of the device.

[0028] This utility model has the following beneficial effects:
