LED (Light-Emitting Diode) display screen box

Abstract

The invention relates to an LED (Light-Emitting Diode) display screen box which comprises a plurality of unit box bodies spliced with one another and rear covers arranged at the back surfaces of the unit box bodies, wherein four sides of each rear cover are provided with avoiding positions; four sides of the back surface of each unit box body are sequentially provided with a first locking plate, a second locking plate and two third locking plates corresponding to the avoiding positions, the first locking plate and the second locking plate are provided with a first threaded through hole and the third locking plates are provided with second threaded through holes larger than the first threaded through holes; the second threaded through holes are provided with regulating pieces; the regulating pieces are provided with three threaded through holes which have the same size with the first threaded through holes; after the third locking plates of each unit box body are aligned with the first locking plates or second locking plates of the adjacent unit box bodies, abutted seams among the box bodies are regulated by virtue of the regulating pieces; the locking pieces penetrate through the third threaded through holes of the regulating piece and the first threaded through holes of the first locking plates or the second locking plates, so that locking is realized. According to the LED display screen box, the abutted seams among the box bodies can be regulated and controlled under the condition that the rear covers are not opened.

Description

technical field [0001] The invention relates to the field of LED display screens, and more specifically, to an LED display screen box. Background technique [0002] As the production technology of LED display becomes more and more mature, its application is becoming more and more extensive. For LED display, especially the ultra-fine-pitch LED display, the demand for fine assembly and adjustment functions has attracted more and more attention from all parties. At present, the LED display systems on the market are assembled by arranging and assembling several LED display cabinets (display units) on structural supports. For the assembly of LED display cabinets, more attention is often paid to efficiency and the adjustability of assembly is easily overlooked. However, most products on the market currently have complex structures, poor stability, and poor stability in the locking structures between LED display cabinets. Disadvantages such as high production cost and non-adjustab...

AI Technical Summary

Problems solved by technology

[0003] At present, in the ever-changing LED market, especially in the market situation where small-pitch LEDs are becoming more and more popular, the cabinet structures of most manufacturers do not have the seam adjustment control function, which cannot meet the objective needs of small-pitch products, that is, when the need Not achievable when seams are properly adjusted
