Description

Technical Field

[0001] The invention belongs to the field of display screen technology equipment, and in particular relates to a maintenance tool and outdoor display screen equipment. Background Art

[0002] In recent years, with the increasing application of outdoor LED fixed screens, the requirements for the installation and daily maintenance of display modules have become increasingly higher, requiring both convenient and quick installation and disassembly without causing damage to the modules and maintenance tools.

[0003] Among them, the suction cup exhaust type front maintenance tool is the most common front maintenance tool on the market. However, when each module is spliced ​​tightly without gaps, it is generally difficult to directly take out the middle part of the module. For the magnetic fixed module, it is easy to cause the module to fall and cause loss at the moment of removal. At the same time, the exhaust type tool is only suitable for modules with flat surfaces. When the module surface has a high brim, it will not work.

[0004] There are also other tools such as L-shaped or T-shaped hexagonal wrenches. Such tools are easy to fall when in use, and there is no effective fixation on the module, which will cause the module to fall easily, posing a safety hazard and causing inconvenience to maintenance personnel.

[0005] Therefore, the existing front maintenance tools on the market are simple and can only disassemble the middle module quick lock, but cannot conveniently remove the module from the screen body. In addition, there is a risk of the module falling during the disassembly process, which can easily cause safety accidents. Summary of the invention

[0006] The purpose of the embodiments of the present application is to provide a maintenance tool to solve the problem of how to quickly and safely disassemble a display module.
