LED (light-emitting diode) display screen box body bracket

Abstract

The invention discloses an LED (light-emitting diode) display screen box body bracket. The bracket comprises a box body, a pedestal, an upper turntable, a lower turntable, a rotating shaft and a spring, wherein the pedestal is hinged to the box body; the upper turntable is fixedly connected with the box body; the lower turntable is fixedly connected with the pedestal; the rotating shaft penetrates through the upper turntable to be connected with the lower turntable; the spring is arranged on the rotating shaft and enables the lower end surface of the upper turntable to be always connected with the upper end surface of the lower turntable in a resisting way; the rotating shaft and the upper turntable are in clearance fit; the upper turntable comprises a standard surface I and a step which is protruded downwards in the manner of being relative to the standard surface I; the lower turntable comprises a standard surface II and a groove which is matched with the step of the upper turntable and is lower than the standard surface II. The bracket is rotationally linked, is inclined, and is simple in structure, simple in operation and stable in adjustment. The bracket can be widely applied to an inclined angle adjusting device of an LED display screen box body.

Description

technical field [0001] The invention relates to an LED display box, in particular to a box bracket. Background technique [0002] With the development of LED technology, LED displays are used more and more widely. The use of LED displays has many advantages and is favored by people, such as low energy consumption, fast response, wide range of working environment temperature, and small size of all firmware equipment. , good impact resistance and long life, etc.; at the same time, it is a semiconductor component, so it can be fully compatible with IC circuits, and the control and drive circuits can be easily integrated into the flat panel display, further reducing the size of the display, and can also facilitate the realization of multiple signals. road transmission. In many large public places, in order to give clear information to the public, large display screens made of LEDs are widely used, such as displaying game information in stadiums. Usually, the auditorium of the ...

AI Technical Summary

Problems solved by technology

Usually, the auditorium of the stadium is set up step by step. Due to the different positions of the audience watching the display screen, there will be deviations in viewing the display screen. In order to avoid this phenomenon, there is usually an adjustable display screen on the back of the display screen An adjustment device for the tilt angle, but the structure is too complicated and difficult to control
