[0002] With the advancement of science and technology and the advent of the digital age, LED display screens have been widely used in advertising, exhibitions, conferences, performances and other fields due to their advantages such as high brightness, high definition, low power consumption and long life. However, with the continuous increase in the size of LED display screens and the continuous enhancement of their functions, their internal structure has become increasingly complex. The main electronic components of LED display screens are all concentrated on their backs. When the LED display screen is in normal use, it is generally provided with a protective shell on the outside and a back cover is generally installed on its back. After the back cover is removed, the electronic components on the back are exposed to the outside, which is convenient for maintenance and other operations, and the back cover is generally fixed by a plurality of fastening screws and other fixing methods.

[0003] However, when multiple fastening screws are used for fixing operations, it takes time to tighten and loosen the fastening screws, especially when there are a large number of fastening screws, which will delay the time. In addition, special tools are required for disassembly, which is cumbersome and inefficient, and is not conducive to portable disassembly for maintenance operations. In view of this, we propose a convenient maintenance back cover structure for LED display screens. Utility Model Content
