[0001] The invention belongs to the field of display screen installation frames, and in particular relates to a display screen installation frame which can be conveniently spliced ​​and maintained. Background Art

[0002] At present, the domestic creative LED display screen is developing rapidly, and a large number of creative display products have emerged, such as curved screens, five-sided screens, sliding screens, rotating screens, and sky curtains. The LED display screen is composed of high-precision aluminum alloy die-casting cabinets and thin modules. The use of aluminum alloy die-casting cabinets to achieve front and rear maintenance of the ceiling screen is the key, and it is a high-density and small-pitch display screen.

[0003] Currently, indoor display screens are made of non-standard designs of sheet metal cabinets. However, the accuracy and reliability of sheet metal are lower than those of die-cast parts, making it difficult to install components and assemble them. In addition, the display screen is fixedly installed on the front of the cabinet, making it difficult to disassemble and assemble the display screen components. The power supply and chassis are installed directly against the cabinet, making it extremely inconvenient to inspect and maintain the power supply and chassis. Therefore, a display screen installation frame that can facilitate splicing and maintenance is proposed. Summary of the Invention
