Base with advantages of being convenient to fold and simple in structure and protecting display screen against attachment of dust

Abstract

The invention relates to the technical field of display screens, and discloses a base with advantages of being convenient to fold and simple in structure and protecting a display screen against attachment of dust. The base comprises a base body. A spring rod is fixedly installed inside the base body, rotating frames are rotationally connected to the left side and the right side of the base body, and a screen protection plate is connected between the rotating frames in a sliding mode. The bottom ends of the rotating frames are rotationally connected with connecting rods, the ends, far away from the rotating frames, of the connecting rods are fixedly connected with rotating wheels, and the surfaces of the rotating wheels are fixedly connected with compression balls. Telescopic rods can freely ascend and descend, and therefore the practical effects of automatic supporting and convenient folding of the display screen are achieved, the structure is simple and is not prone to damage, and the display screen is protected from being easily broken by a naughty child; and the rotating frames drive the connecting rods to act on the rotating wheels to enable the compression balls to extrude compression air bags, and therefore the dust on the screen protection plate is prevented from being attached to the display screen, the dustproof effect on the display screen is greatly improved, and the dust is prevented from affecting the watching effect of the display screen.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a base that is convenient to fold and has a simple structure and protects the display screen from dust. 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 liquid crystal molecules to generate points, lines, and surfaces to form a picture with the back lamp tube, which brings a lot of colors to people's life, but because the surface of the screen is very fragile, it is easy to place it vertically on the table It is accidentally broken by children while playing, causing economic losses, and the display itself is easy...
