Description

LED display box

Technical Field

The utility model relates to the field of display screen boxes, in particular to an LED display screen box.

Background Art

With the development of science and technology, display screens have become an important information output tool in various outdoor equipment. LED display screens are electronic display screens composed of LED dot matrixes. By turning on and off the lamp beads, the screen display content forms such as text, animation, pictures, and videos are changed in a timely manner, and the component display control is performed through a modular structure. The more common LED display screens are the LED display screens seen in front of the glass windows of major shopping malls, or the outdoor LED display screens embedded in the outer wall of the building wall, or the display screens used in stage venues formed by splicing through brackets. Therefore, for the display screens required for venues, concerts, stages, etc., they are generally formed by splicing the display screen cabinets.

Therefore, in order to ensure the normal operation of the display screen under various environmental conditions, it needs to be installed in a special box. The set box can not only protect the display screen from environmental factors, but also help assemble and fix the display screen so that it can work stably during use.

The existing LED display cabinet has structural defects. The cabinet structure is generally formed by die-casting, so that the display screen is installed on the open side of the cabinet. The outer shell of the existing cabinet is easily deformed or damaged by external forces, resulting in an unstable installation structure, which affects the normal use of the LED display screen. In addition, the existing display cabinet is generally formed by metal die-casting, and the LED display screen generates a large amount of heat when working. The ventilation and heat dissipation performance of the metal cabinet is poor, which will cause heat accumulation, thereby affecting the life of the LED lamp beads and the display effect, making it unfavorable for the stable use of the display screen.
