A retractable led display fixing mechanism

Abstract

A telescopic LED display screen fixing mechanism comprises a frame body, a set screw arranged on the side wall of the frame body and extending out of a cavity of the frame body, a supporting rod arranged beside the set screw and penetrating two opposite side walls of the frame body, a handle arranged at one end of the supporting rod, a connecting fork arranged at other end of the supporting rod, clamping blocks arranged on the upper cover plate and the lower cover plate of the frame body, penetrating the top of the supporting rod and extending out of the upper cover plate, and a spring arranged between the clamping block and the lower cover plate. A square shaft is arranged on the supporting rod, a hole for the supporting rod to pass through in each clamping block includes a round hole capable of being matched with a supporting rod circular shaft at the upper portion and a long hole closely following on the lower portion of the round hole and capable of being matched with the square shaft of the supporting rod. By utilizing telescopic and rotary functions of the supporting rod, an LED display screen can be conveniently and quickly, the evenness of the display face of the LED display screen can be ensured, and the displaying effect can be improved.

Description

technical field [0001] The invention relates to an LED display screen, in particular to a retractable LED display screen fixing mechanism. Background technique [0002] A large LED display is a display device formed by splicing many display units. The spliced ​​LED display needs to be fixed in place by a fixing mechanism. The current LED display is widely used, and has been widely used in outdoor advertising media, program performances, large conferences and other fields. As a fixed mechanism of LED display, it is an indispensable part of LED display. However, the existing fixing parts have always troubled the convenience and display effect of LED display screen fixing: [0003] 1. The fixing method of the LED display is cumbersome [0004] The existing display screens are fixed in a way of connecting pieces and screws. The disadvantage of this fixing method is that each connecting piece must be equipped with 4 screws, the fixing method is too cumbersome, the speed is sl...

AI Technical Summary

Problems solved by technology

The disadvantage of this fixing method is that each connecting piece must be equipped with 4 screws, the fixing method is too cumbersome, the speed is slow, and the fixing method is not convenient

[0005] 2. The fixing effect of the LED display is poor

[0006] The disadvantage of fixing the LED display screen with connecting piece and screws is that it is difficult to ensure that the strength of the four screws on the connecting piece is consistent during the process of fixing the display screen, which will lead to poor flatness of the LED display surface and poor display effect.
