A front maintenance structure of LED display screen

Abstract

A front maintenance structure of an LED display, the front maintenance structure includes a component box fixedly connected to the horizontal and vertical frames of the display screen, the component box includes an upper cover and a base fixedly connected as an integral structure, and a disassembly The unit module, the structure of disassembling the unit module includes installing the positioning column and unlocking the driving column. The upper cover is provided with a first half groove that is slidingly fitted with the installation positioning column, and a second half groove that is slidingly fitted with the unlocking driving column. Both the bottom of the first half groove and the second half groove are provided with springs; the base is provided with a torsion spring positioning column, a torsion spring fixed end, a torsion spring, an equal-diameter through groove, and a variable-diameter through-pass with a stepped limit platform. slot, the installation positioning post is arranged in the equal-diameter through-slot, the unlocking drive post is arranged in the variable-diameter through-slot, the equal-diameter through-slot corresponds to the first half-slot, and the variable-diameter through-slot corresponds to the second half-slot. The invention has simple structure, convenient installation and disassembly, and fundamentally solves the technical problem of front maintenance of the LED display screen.

Description

technical field [0001] The invention belongs to the technical field of LED display screen maintenance, and in particular relates to a front maintenance structure of an LED display screen. Background technique [0002] With the rapid development of the LED display industry, both the quantity and the quality of LED displays are constantly improving. More and more manufacturers are beginning to pay attention to quality issues on the premise of ensuring quantity. Product repair and maintenance issues. At present, the maintenance of the LED display includes front maintenance and rear maintenance. After the maintenance, when the disassembler disassembles or repairs the problematic module, it needs to be disassembled by screwing the screws very complicatedly. The screwing process is very troublesome. [0003] At present, a front maintenance mechanism with a simple combination of an extension mechanism and a flip mechanism has appeared on the market to solve the limitation on the ...

Problems solved by technology

However, this structure does not fundamentally solve the technical problems of front maintenance, and the structure is relatively complicated and inconvenient to adjust

[0004] The application date published by the State Intellectual Property Office of China is November 25, 2013, and the patent "a front maintenance LED display" with the publication number CN103646616A discloses a principle of using an SD card slot, through a fixed plate and a fixed card slot With the cooperation of the SD card, the idea of ​​pressing the SD card to fix it and then pressing it to pop up is proposed, but it does not give a practical and specific structure. Although this idea is very good, it can be realized for lighter things such as umbrellas. , and the problem we want to solve is the front maintenance of the LED display, and the weight of the LED display module is relatively heavy. Using the structure of the SD card slot, first of all, the structure of the card slot has low sensitivity and is prone to loosening or jamming The phenomenon, the application is very inconvenient, although it is theoretically feasible, it cannot be realized in actual implementation and operation
