An optional led display box

Abstract

The present invention provides an optional LED display box, including a protection box; two cooling fans are installed on the left inner wall of the protection box; and a folding crank is rotatably connected to the bottom of the rear side of the protection box , and the front end of the folding handle is meshed with the bottom of the driving screw, and the driving screw is threadedly connected with a control slider; the driving screw is connected with the driven screw through a synchronous belt; the present invention uses the rotating driving screw and the driven screw The screw changes the lifting and lowering of the control slider, so that the control slider controls the opening and closing of the bottom of the display connection frame through the support arm, which is beneficial to change the angle between the left side wall of the display connection frame and the right side wall of the protective box, thereby changing the display The display angle of the screen connection frame makes the LED display screen connected to the display screen connection frame have a better display effect, which improves the display effect of the LED display screen and increases the convenience for the maintenance of the LED display screen.

Description

technical field [0001] The invention belongs to the technical field of LED display screen boxes, and more particularly, particularly relates to an optional LED display screen box body. Background technique [0002] The LED display box is simply a combination of several display units and metal boxes plus a set of appropriate controllers to meet the use of different environments, so a variety of specifications of the display panels with different control technologies The controller can form many kinds of LED display. [0003] The optional LED display box can refer to the patent CN106548714B, which mainly includes a support frame, an LED module, a box back cover and a drive assembly. The LED module is installed at the front end of the support frame. The rear cover of the box body is installed at the rear end of the support frame, the support frame, the rear cover of the box body and the LED module are jointly formed to form an accommodating space, and the drive assembly is acc...

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
