LED display screen box body capable of being selectively used

Abstract

The invention provides an LED display screen box body capable of being selectively used. The LED display screen box body comprises a protection box, two cooling fans are mounted on the inner wall of the left side of the protection box; a folding crank is rotatably connected to the bottom of the rear side of the protection box, the front end of the folding crank is in engaged connection with the bottom of a driving screw rod, and a control sliding block is in threaded connection to the driving screw rod; the driving screw rod is in transmission connection with a driven screw rod through a synchronous belt; lifting of the control sliding block is changed through the rotating driving screw and driven screw, so that the control sliding block controls opening and closing of the bottom of a display screen connecting frame through a supporting arm, the included angle between the left side wall of the display screen connecting frame and the right side wall of the protection box can be changed, and the display angle of the display screen connecting frame is changed; the LED display screen connected to the display screen connecting frame has a better display effect, the display effect of the LED display screen is improved, and meanwhile the maintenance convenience of the LED display screen is improved.

Description

technical field [0001] The invention belongs to the technical field of LED display boxes, and more specifically relates to an optional LED display box. Background technique [0002] Simply speaking, the LED display box is a combination of several display units and metal boxes plus a set of appropriate controllers to meet the use of different environments. Therefore, display panels of various specifications are matched with different control technologies. The controller can form many kinds of LED displays. [0003] The optional LED display cabinet can refer to patent CN106548714B, which mainly includes a support frame, an LED module, a rear cover of the cabinet and a drive assembly. The LED module is installed on the front end of the support frame. The back cover of the box body is installed on the back end of the support frame, and the support frame, the back cover of the box body and the LED module are jointly surrounded to form an accommodating space, and the drive assemb...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an optional LED display box to solve the problem that most of the existing similar optional LED display boxes fix the LED display to the LED display box. In addition, the LED display cannot be adjusted in angle, resulting in limited display effect of the LED display, and most of the LED displays are used outdoors. The waterproof effect of the existing LED display cabinet is not very good, and rainwater can easily pass through the LED display. The heat dissipation holes of the screen box seep into the box, causing moisture inside the LED display box, which can easily cause short circuit problems
