In art design, the design content is often displayed through multimedia display devices so that people can watch and understand the design content.

[0003] For example, the Chinese utility model patent with publication number "CN218208798U" discloses a multimedia display device for environmental art design. By using a rotating shaft and an adjusting bolt structure in the installation frame, the staff can adjust the placement angle of the installation frame and the display screen, thereby avoiding the influence of light, improving the display effect of the device, and improving the flexibility of use of the device.

[0004] However, in the above-mentioned patent, although the structure of the prior art can realize the display of the display screen at different placement angles, when such display devices are actually used, the display screen for external display is often directly exposed to the air without other auxiliary assembly. When the display screen is stored after use, it is easy to be contaminated by external dust, and the display screen is easy to be damaged when the device is moved. In addition, the effect of reducing the influence of light in actual use by only flipping and adjusting the display screen is limited. Utility Model Content
