Description

LED display module quick locking structure

Technical Field

The utility model relates to the technical field of LED display screens, in particular to a quick locking structure for an LED display screen module.

Background Art

Light emitting diode (LED) is abbreviated as LED. LED display screen is composed of many LEDs. It can display various information such as text, graphics, images, animation, market conditions, videos, and video signals by controlling the on and off of LEDs. LED display screen is also called electronic display screen or floating text screen. The content can be changed at any time, and each component is a display device with modular structure. It is usually composed of display module, control system and power supply system. The display module is composed of a dot matrix composed of LED lights, which is responsible for luminous display; the control system can display text, pictures, videos, etc. on the screen by controlling the on and off of the corresponding area; the power supply system is responsible for converting the input voltage and current into the voltage and current required by the display screen. LED display screen can display changing numbers, text, graphics, images, and videos; it can be used not only in indoor environments but also in outdoor environments, and has advantages that projectors, TV walls, and LCD screens cannot match.

LED display screens are generally formed by splicing together multiple smaller independent LED display screen modules. Each independent display module can work independently or be spliced together to work in combination. Usually, the LED display screen system is formed by multiple LED display screen modules through a mounting rack to form a large LED display screen. Because LED display screen systems are often used outdoors or in public places, for safety reasons, the mounting rack part is usually hidden and fixed, which often involves the front disassembly and maintenance of LED display screen modules, that is, taking out the LED display screen module from the front side of the LED display screen and performing maintenance. The existing front disassembly device of the LED display screen module generally absorbs the LED display screen module through a magnet assembly, thereby enabling the disassembly of the LED display screen module. The existing front disassembly device of the LED display screen module has a complex structure, and the magnetic suction method is prone to failure over time, resulting in an inability to unlock. Therefore, it is necessary to further improve the existing front disassembly device of the LED display screen module.
