Head-up, looking up one-step quick conversion bracket

Abstract

The invention discloses a support enabling switching between the horizontal watching state and the looking-up watching state to be achieved rapidly in a one-step mode and belongs to the technical field of supports for display devices such as flat televisions, flat-panel displayers and computer all-in-one machines. The support enabling switching between the horizontal watching state and the looking-up watching state to be achieved rapidly in the one-step mode is simple in structure, rapid falling and rising can be achieved, and the angles of the display devices can be changed synchronously. The support comprises a four-bar mechanism which is formed by hinging a machine frame base, an upper rocker arm, a connecting arm rod and a lower rocker arm in sequence in an end-to-end mode. The support is characterized by further comprising a telescopic rod, one end of the telescopic rod is hinged to the machine frame base, and the other end of the telescopic rod is hinged to the upper rocker arm or the lower rocker arm.

Description

technical field [0001] The invention belongs to the technical field of brackets for display devices such as flat-panel TVs, flat-panel displays, and integrated computers. Background technique [0002] There is no display device support in the market that can take into account both sitting and lying positions, can be quickly converted, and has a wide range of applications. [0003] At present, there is a wall-mounted TV stand with a lifting function, such as the patent number: 201120480832.X, which is a utility model patent named "Slide Type Display Lifter", which controls the display screen up and down through the form of gears and racks. Its transmission mechanism is complex, the rack and pinion require high precision, difficult processing, high cost, slow lifting speed, and only the lifting function can be realized, and the angle of the display screen cannot be rotated. [0004] The patent number is 201220086366.1, and the name is a utility model patent of "liftable TV st...

Problems solved by technology

[0005] The patent number is 201110211829.2, and the name is the invention patent of "An Angle-Adjustable TV Hanger", which realizes the angle adjustment of the flat-panel TV through the cooperation of the adjustment pin and the card position in the keyway, and it does not have the lifting function; in addition, its The angle adjustment structure is also more complicated

When adjusting the angle, you need to pull the pull cord to control the adjustment pin to enter and exit the card slot through the movement of the inclined block; it has the following disadvantages: 1. The size of the inclined block is proportional to the tilt angle of the TV; big

[0010]There are also some ceiling-mounted TV stands, although they meet the requirements of looking up, they cannot meet the requirements of looking up, cannot be lowered low enough, and cannot be attached to the wall. It takes up a lot of space, and it is inconvenient to increase the viewing distance
