Pre-maintenance LED display screen and maintaining method thereof

Abstract

The invention discloses a pre-maintenance LED display screen and a maintaining method thereof. The pre-maintenance LED display screen comprises at least two LED display boxes and a splicing device. Each LED display box comprises a frame and at least two LED display modules. A power pack is fixedly arranged on the back of the frame. Connecting portions are arranged on the first side edge and the second side edge of the frame. Fixing portions are arranged on the third side edge and the fourth side edge. The splicing device comprises a rapid lock and a rapid lock fixing base. The rapid lock is installed on the connecting portion. The rapid lock fixing base is installed on the fixing portion. The rapid lock comprises a lock catch and a spanner. The rapid lock fixing base comprises a base, a connecting plate, a first clamping tongue and a second clamping tongue, wherein the first clamping tongue and the second clamping tongue are arranged on the two sides of the connecting plate and symmetric with each other. By adopting the scheme, the pre-maintenance LED display screen is simple in structure and easy to install and maintain, the LED module assembling and disassembling speed is high, the pre-maintenance LED display screen particularly meets the requirement for narrow installation environment or rapid installation, workloads of front-line workers are greatly reduced, and the good market application value is achieved.

Description

technical field [0001] The invention relates to the technical field of LED displays, in particular to a front maintenance LED display screen and a maintenance method thereof. Background technique [0002] With the development of technology, due to the advantages of seamless splicing, cost reduction, and the development of high-density display screens, the existing LED display screens are more and more widely used in the field of indoor display, and the market share in the field of advertising and information release getting bigger. [0003] However, the existing LED display screens are generally based on future maintenance. Since the post-maintenance needs to leave a large maintenance channel behind the display screen, the installation and maintenance of the display screen will take up a lot of space, and the overall appearance is very complicated. Thick, which restricts the promotion and use of LED displays indoors; therefore, it is particularly important for convenient an...

Problems solved by technology

[0003] However, the existing LED display screens are generally based on future maintenance. Since the post-maintenance needs to leave a large maintenance channel behind the display screen, the installation and maintenance of the display screen will take up a lot of space, and the overall appearance is very complicated. thick, which restricts the promotion and use of LED displays indoors; therefore, it is particularly important for convenient and reliable front maintenance LED displays

[0004] However, the existing front-maintenance LED display screen can only maintain some parts, and other parts still need post-maintenance, so that the installation space for post-maintenance cannot be saved, and it is very inconvenient to operate and has low reliability. needs, therefore, the existing technology is flawed and needs to be improved
