Front maintenance device of LED display box body and assembling method of LED display screen

Abstract

The invention relates to a front maintenance device of an LED display box. The device comprises an adsorption connecting part corresponding to odd rows of an LED display box body of an LED display screen and an adsorption limiting hanging mechanism part corresponding to even rows of the LED display box body of the LED display screen, wherein magnetic steel on the LED display box body in the adsorption connecting part and a magnetic steel adsorption plate on a vertical back frame are adsorbed and fixed; and step magnetic steel on the LED display box body in the adsorption limiting hanging mechanism part is hung on a box body clamping piece and is adsorbed and fixed by a magnetic steel sticking plate on a vertical back frame. During maintenance, the LED display box body in odd-numbered rowscan be directly pulled out for maintenance; for the LED display box body in the even-numbered rows, the LED display box body in the previous row is horizontally drawn out, and then the LED display boxbody is upwards lifted and drawn out, so that the LED display box body can be maintained. The assembling efficiency of the display screen can be improved, and later maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a front maintenance device for an LED display box and an assembly method thereof. Background technique [0002] LED display box (LED display) is a flat-panel display unit, which is composed of one or more LED module panels and a die-cast metal box, and is used to display various information such as text, images, videos, and video signals. [0003] At present, the front maintenance of LED display is a major trend in the market. The installation of the existing LED display is mainly realized by the front maintenance of the display module. When it is applied to a large-scale front maintenance LED display project, the front maintenance of the module has a natural sagging extrusion, which increases the failure rate. Small unit display modules The splicing of the screen is cumbersome and the structure is complex. Usually, it is necessary to design and manufacture a special...

AI Technical Summary

Problems solved by technology

The installation of the existing LED display is mainly realized by the front maintenance of the display module. When it is applied to a large-scale front maintenance LED display project, the front maintenance of the module has a natural sagging extrusion, which increases the failure rate. Small unit display modules The splicing of the screen is cumbersome and the structure is complex. Usually, it is necessary to design and manufacture a special box mold to adapt to the front maintenance and installation of the unit module. The cost is high, the labor waste is large, and the efficiency is low.
