Description

Technical Field

[0001] The utility model specifically relates to a front maintenance device for an LED display screen panel, belonging to the technical field of display screens. Background Art

[0002] The panel-level front maintenance device for LED display screens is designed specifically for LED display screens to facilitate maintenance and repair directly from the front without having to go to the back of the screen or dismantle the entire screen. This design is particularly suitable for indoor or space-limited installation environments because it greatly reduces the need for maintenance channels, thereby saving space and costs. However, when using existing maintenance devices, suction cups are usually used to remove the single display screen from the whole for inspection and maintenance. When removing a single display screen, the display screen is prone to slide down on the suction cup under the action of its own gravity, which can easily cause the display screen to fall and damage the display screen. At the same time, when the existing maintenance device is used to maintain the single display screen, it needs to be frequently installed and disassembled, which is not flexible and convenient to use, and there are certain disadvantages in the use process.
