Height adjusting mechanism of floor model support

Abstract

The invention discloses a height adjusting mechanism of a floor model support. The height adjusting mechanism of the floor model support comprises an upper stand column, a lower stand column, a clamping part and an elastic part, wherein the upper stand column is vertically inserted into the lower stand column in a slidable manner, a plurality of inserting openings which are arranged in the vertical direction are formed in the side wall of the upper stand column at intervals, the clamping part is installed on the lower stand column in the manner of being capable of rotating around a horizontal shaft, a ratchet tooth structure is formed at one end of the clamping part and can just stretch into one inserting opening in the side wall of the upper stand column, the ratchet tooth structure of the clamping part only allows the upper stand column to slide upwards, the elastic part can provide set retentivity, for stretching into one inserting opening in the side wall of the upper stand column, for one end of the clamping part, and a driving mechanism which can drive the clamping part to rotate so that one end of the clamping part can get out of one inserting opening of the upper stand column is further arranged on the side wall of the lower stand column. With the height adjusting mechanism of the floor model support, the height of a television set can be adjusted conveniently by only one person, both time and labor are saved, adjustment is safe and reliable, and the television set will not slide down because of self-gravity after long-term use, and can keep the stable position state for a long time.

Description

technical field [0001] The invention relates to a TV bracket, in particular to a floor-standing bracket height adjustment mechanism. Background technique [0002] Floor-standing TV brackets often need to have a TV height adjustment function. At present, floor-standing TV racks mainly adopt the following schemes for TV height adjustment: [0003] The first type: using the slider clamping mechanism, by setting the slider on the lower column to match the T-shaped chute of the upper column, the side walls of the slider and the T-shaped chute of the upper column at different heights are kept clamped by bolts The upper and lower columns are kept in a fixed connection state through friction. This adjustment method requires the cooperation of two people, which is inconvenient to adjust, and the wear of the slider after long-term use will easily lead to failure. During the adjustment process, it is easy to get stuck when sliding quickly. , difficult to adjust; [0004] The second t...

[0005] The third method is to adjust the height of the TV through the friction locking structure of the hanging board and the column. This is similar to the first method, but it is also inconvenient to adjust, requires the cooperation of multiple people, and is prone to wear and tear.
