LED (Light-Emitting Diode) box body, LED display screen and maintenance tool

Abstract

The invention discloses an LED (Light-Emitting Diode) box body, which approximately comprises a module and an installing frame, wherein the module comprises a veil, a PCB (Printed Circuit Board) lamp board and a bottom shell, and the bottom shell of the module and the installing frame are magnetically adsorbed and fixed; the veil, a PCB lamp board and the bottom shell are fixedly connected; and a bolt is arranged on the veil of the module, and a clamping space is left between a screw cap of the bolt and the outer surface of the veil. In an LED display screen disclosed by the invention, by adopting a magnetically adsorbing and fixing structure of the bottom shell of the module and the installing frame, the module is more convenient and rapider to install, the work efficiency is improved, and meanwhile, the problem that the bolt is easy to fall when the bolt is assembled and disassembled is solved; and a structure that the clamping space is left between the screw cap of the bolt and the outer surface of the veil is adopted by the invention, so that a maintenance tool can be conveniently utilized for clamping the bolt on the veil of the module, the module can be more conveniently assembled and disassembled, and the work efficiency is further improved.

Description

technical field [0001] The invention relates to the field of LED displays, in particular to an LED box body, an LED display screen and a maintenance tool. Background technique [0002] At present, LED displays have been widely used in various occasions. As an electronic product, these LED displays will inevitably fail or age as time goes by. Therefore, the maintenance method should be the current LED display An important content to be considered in the design of the screen circuit and structure. [0003] The LED display screen in the prior art mainly realizes its huge display area by splicing modules into cabinets and splicing the cabinets into large screens. Although the sizes of the modules vary, their structures are basically the same. They are generally composed of a mask, a PCB light board and a bottom shell. To increase the contrast, when the module is assembled on the box, the usual fixing method is to embed a copper column that can be driven into the bottom shell, ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem mainly solved by the present invention is that the installation environment of the box is relatively narrow, and it is extremely inconvenient for the maintenance personnel to work in the space; when the module is fixedly installed and disassembled, the back door of the display box needs to be opened, causing the screws to fall; after the module is powered on, it is necessary to For the problem of viewing the picture playing on the front of the display screen, the present invention provides an LED cabinet and LED display screen that can quickly perform maintenance before the module on the front of the display screen without opening the back door of the display screen cabinet and without disassembling the mounting screws.
