LED (Light Emitting Diode) combined screen latching mechanism, LED unit screen and LED combined screen

Abstract

The invention discloses an LED (Light Emitting Diode) combined screen latching mechanism, an LED unit screen and an LED combined screen. The LED combined screen latching mechanism comprises a first connecting part and a second connecting part, wherein the first connecting part comprises a slide block, a locating pin, a first screen board and a locating pin offsetting spring; the first screen board comprises a shaft hole of the locating pin and a longitudinal slideway of the slide block, and the locating pin is inserted to the shaft hole of the locating pin from the front to the back; the second connecting part comprises a latch hook, a wrench and a second screen board, the wrench is hinged with the second screen board, and the rear end of the latch hook is hinged with the wrench; and when the latching mechanism is latched, a hook head at the front end of the latch hook is lapped and hung on the slide block, the slide block slides along the slideway, and the rear end of the locating pin is inserted to a locating pin hole of the second screen board, so that the first screen board and the second screen board are connected together. When being used for splicing the unit screen, the LED combined screen latching mechanism is free of using an auxiliary mounting tool or high professional staff, time-saving and labor-saving purposes are achieved in the assembling process, the splicing precision is high, and the LED combined screen latching mechanism is suitable for splicing a display screen with high resolution.

Description

[technical field] [0001] The invention relates to an LED electronic display screen, in particular to a locking mechanism for an LED combined screen, an LED unit screen and an LED combined screen. [Background technique] [0002] Due to its excellent display effect and applicability, LED electronic display screens have been widely used in stages, commercial performances, advertisements, exhibitions and other industries. LED electronic display screens are generally composed of smaller unit screens. When the demand for display area is large, dozens or even hundreds of unit screens may be assembled and used together, which requires a lot of manpower and material resources of the display provider to install and disassemble. . [0003] With the growing maturity of the display screen rental market, higher requirements are put forward for the convenience and safety of display screen assembly and disassembly. The traditional LED display generally uses parts such as pull locks or con...

AI Technical Summary

Problems solved by technology

The traditional LED display generally uses parts such as pull locks or connecting pieces to assemble the unit screens. When fixing the unit screens, auxiliary installation tools must be used. It is difficult for one person to assemble, time-consuming and labor-intensive. The positioning between the unit screens requires Relying on the addition of positioning pins, it is difficult to control the seam gap, and the assembled display screen is not easy to disassemble. The traditional assembly structure is especially not suitable for high-resolution display screens that require high seam accuracy.
