[0002] At present, many public places need to display or broadcast pictures, texts, videos, etc. through display screens. The common installation methods of display screens in public places are mainly floor-standing bracket installation, wall-mounted installation and ceiling hanging. Among them, the ceiling hanging method saves ground space and can be installed in various positions indoors, especially in the middle of the room. The display screen can be oriented to any position as needed without being restricted by the wall. Therefore, the hanging method is widely used. The current structure of the hanging display screen installation bracket mostly includes a wall panel for installation on the ceiling, a vertically extending hanging pipe, a crisscross frame for installing the display screen and a connecting swivel. The upper end of the hanging pipe is fixedly connected to the wall panel, the swivel is fixedly installed at the lower end of the hanging pipe, the crisscross frame is installed on the swivel, and the display screen is installed on the crisscross frame. This display screen hanger structure is relatively complex and has high manufacturing costs. The weight of the display screen will cause the hanging tube to tilt, which in turn makes it difficult for the display screen to remain vertical and will result in a certain tilt. If this structure needs to install two back-to-back display screens, two brackets are required, or a double swivel head is set at the lower end of the hanging tube. The two display screens are installed through two cross-shaped frames. The distance between the two display screens is large, making it difficult to form a compact position state. The display screen hanger structure of this type also causes dust to accumulate on the display screen and the connecting parts between the two display screens, making them difficult to clean.
