Adjustable support for liquid crystal display

Abstract

The invention discloses an adjustable support for a liquid crystal display. The adjustable support comprises a base, wherein a supporting column is fixedly welded to the middle of the top surface of the base; a mounting frame is rotatably connected to the top surface of the supporting column through a bearing; a one-way screw rod is rotatably connected between the top and the bottom of the inner wall of the supporting column; a first sliding sleeve sleeves the surface of the one-way screw rod in a threaded mode; and driven wheels fixedly sleeve the surface of the bottom of the one-way screw rod. The problems that an existing support and the liquid crystal display are fixedly welded and when the liquid crystal display needs repair and maintenance, the liquid crystal display and the supportcannot be quickly disassembled and installed, so that the inconvenience of repair and maintenance is easy to cause; and the existing support can only match with the liquid crystal display with one specification, cannot adjust the angle of the liquid crystal display and cannot be suitable for different people to use are solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display screens, in particular to an adjustable bracket for liquid crystal display screens. Background technique [0002] Liquid crystal display is a flat and ultra-thin display device. It is composed of a certain number of color or black and white pixels and is placed in front of a light source or reflective surface. The power consumption of liquid crystal displays is very low, so it is favored by engineers and is suitable for electronic devices that use batteries , Its main principle is to stimulate the liquid crystal molecules to generate points, lines and surfaces with the back lamp to form a picture. [0003] However, there are some disadvantages in the traditional use process, such as: [0004] 1. The existing bracket and the LCD screen are fixedly welded. When the LCD screen needs to be repaired and overhauled, the LCD screen and the bracket cannot be disassembled and installed quic...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing bracket and the LCD screen are fixedly welded. When the LCD screen needs to be repaired and overhauled, the LCD screen and the bracket cannot be disassembled and installed quickly, which will easily cause maintenance and overhaul. Inconvenience, and the existing bracket can only be used with one type of LCD screen, which has limitations

[0005] 2. The existing brackets cannot adjust the angle of the LCD screen. Users who watch the LCD screen at an uncomfortable angle for a long time may easily cause discomfort in the cervical spine. They cannot be used by different people and have low practicability.
