Holding device and image display device using the holding device

Abstract

The subject of the invention is to provide a retaining device and an image display device using the retaining device. The retaining device is formed by a left-right swing control device and an up-down swing control device which comprise a left-right swing locking device and an up-down swing locking device, wherein the left-right swing locking device and an up-down swing locking device are installed on a hinger bar for left-right swinging and on a hinger bar for up-down swinging and comprise fixed gears and rotary gears, wave-shaped washers, elastic assemblies and push-press washers, and also comprise a left-right locking rod and an up-down locking rod which are abutted to the push-press washers and assembled to the left-right swing hinge bar and the up-down swing hinge bar. The fixed gears and the rotary gears are occluded; the wave-shaped washers are installed between the fixed gears and the rotary gears; compression joint is formed between the fixed gears and the rotary gears by the elastic assemblies; the left-right locking rod and the up-down locking rod make the fixed gears and the rotary gears clamped together or detached.

Description

technical field [0001] The present invention relates to a holding device for an image display device such as a TV monitor and an image display device using the holding device, wherein the TV monitor may include a liquid crystal TV or a plasma TV, for example. Background technique [0002] In the prior art, as described in the following patent document 1 and patent document 2, it is a well-known technique to use a holding device to assemble an image display device such as a TV monitor to a supporting device such as a wall. Although this known holding device can make the image display device swing forward and backward while maintaining the image display device, in order to keep the image display device at the required angle, and not cause the image display device to be held at a desired angle without due to its own weight, vibration or The inclination angle of the image display device changes due to other reasons. The conventional holding device usually has a friction mechanis...

Problems solved by technology

[0005] However, although the holding device in the above-mentioned prior art document can be applied to the case where the image display device is small and light, or the installation state of the image display device does not bring an excessive frictional moment to the holding device, it is not suitable for the image display device. When the display device is large and heavy, or the image display device is assembled on the wall, etc., so that a large frictional moment is applied to the holding device, the inclination angle of the image display device will change over time , thus having the disadvantage of being impractical

And even if a locking device is additionally provided in the holding device, if the user inadvertently changes the inclination angle without releasing the lock, or when the image display device shakes greatly due to factors such as earthquakes, the locking device may be damaged, which is in vain. Increased troubles in use
