Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a bottom shell structure of an LED display screen with strong applicability. Background Art

[0002] The LED display screen is an electronic display screen composed of LED dot matrix. It can timely convert the screen display content such as text, animation, picture, video by turning on and off the red and green light beads. The component display control is carried out through a modular structure. It is mainly divided into display module, control system and power supply system. The display module is composed of LED light matrix to emit light on the screen. The control system regulates the on and off conditions in the area to realize the conversion of the content displayed on the screen. The power supply system converts the input voltage and current to meet the needs of the display screen. The LED screen can realize the conversion between different forms of various information presentation modes and can be used indoors and outdoors. It has incomparable advantages over other display screens. It has the characteristics of high light intensity, low power consumption, low voltage requirement, small and convenient equipment, long service life, stable impact resistance and strong resistance to external interference. It has developed rapidly and is widely used in various fields.

[0003] For example, the Chinese utility model patent with announcement number CN202394471U discloses a bottom shell of an LED display module, including a bottom shell, which is fixedly connected to one side of a light board through a plurality of copper pillars, and the ends of the copper pillars extend to contact the light board. When in use, the ends of the copper pillars extend to contact the light board, so that the light board is grounded through the copper pillars, thereby cleverly solving the problem of difficulty in grounding the light board and playing a good shielding role on the front of the LED display.

[0004] The above solution has the following problems: the LED display screen may have different lengths during installation. When this happens, the device cannot freely adjust the length and the bottom shell needs to be re-customized. Re-customization requires manpower, material resources and time, which slows down the installation progress.

[0005] Therefore, we propose a LED display screen bottom shell structure with strong applicability to solve the above-mentioned problems. Utility Model Content

[0012] By adopting the above technical solution, the connecting block can be connected to the movable groove on the main shell through the fixed rod and the connecting rod, so that the connecting block can move freely in the movable groove as the turning handle rotates, and the main shell can move in the sliding groove as the connecting block moves in the movable groove, thereby achieving the purpose of controlling the movement of the main shell.

[0013] As a preferred technical solution of the utility model, a plurality of heat dissipation holes are provided on the main shell; the heat dissipation holes are designed to be centrally symmetrical on the left and right shells of the main shell.
