[0002] An LED curtain wall is an innovative application that combines LED display technology with building facades, and is usually used in large buildings such as commercial buildings, hotels, shopping centers, and stadiums. The main applications of LED curtain walls are generally: advertising, building decoration, information dissemination, art performances, and interactive experiences. Due to its flexibility, customizability, and strong visual impact, LED curtain walls are widely used in daily commercial scenarios.

[0003] Especially for the LED curtain walls on large concerts and stages, they need to be hoisted and installed quickly during installation. In order to meet personalized requirements, it is also required that the LED curtain wall can form curved surfaces, such as outer arc-shaped, inner arc-shaped, and wavy curved curtain walls. However, to achieve the curved surface modeling of the LED curtain wall and realize various curved surface displays, it is necessary to rely on the installation base of the module, that is, the LED display module base called the "hanging floor beam" in the industry. The hanging floor beam needs to have the ability to rotate, unfold, and contract, so that the LED display modules installed on the hanging floor beam can form an inner arc surface or an outer arc surface. By combining an appropriate number of inner arc surface or outer arc surface LED display modules, a large LED curtain wall with a curved surface modeling can be formed.

[0004] Disadvantages of the existing technology of the hanging floor beam:

[0005] (1) The existing hanging floor beam usually has an unfolding angle of only ±20 - 30 degrees, which is difficult to meet the continuously rapidly changing curved surface modeling.

[0006] (2) The existing unfolding structure of the hanging floor beam is not smooth when unfolding the hanging floor beam, and it is more troublesome to use.

[0007] (3) The existing hanging floor beam can only be used as a base and cannot be used as a top mounting part, and does not have a dual-purpose function.

[0008] (4) The existing fixing method of the hanging floor beam is relatively single, and it can only be fixed by fixing hooks or connecting shafts, which is not convenient for installation.

[0009] In summary, it is found that the existing technology has at least the following technical problems:

[0010] For the existing hanging floor beam device, there are problems that the unfolding angle is small, the unfolding is not smooth, and the fixing method is single, resulting in the inconvenience of installing a curved surface modeling curtain wall with the hanging floor beam.
