Problems solved by technology

[0005] However, this liquid crystal display lifting mechanism adopts the lifting block 6 to cooperate with the lifting seat 5. Although the lifting adjustment function can be realized, in order to ensure that the lifting block 6 has sufficient strength to support the liquid crystal display screen, the lifting block 6 usually has a larger weight. and volume, and the lifting seat 5 matched with the lifting block 6 also has a relatively large weight and volume, resulting in a large weight and high manufacturing cost of the entire lifting mechanism.
In addition, the lifting mechanism realizes the positioning at the desired position through the friction force between the lifting block 6 and the lifting seat 5, but the friction force is limited, and the impact of external force is likely to cause the liquid crystal display to drop suddenly. Therefore, the stability of the lifting mechanism poor

Abstract

The invention provides an elevator mechanism, which comprises a bracket, a sliding panel, two roller components, a transmission component and a gravity balance device. The roller components comprise two rollers which are rotatably arranged on the roller components. The transmission component comprises two racks and at least two gears. The two racks are symmetrically arranged on the bracket. The at least two racks are arranged on the sliding panel and meshed with the rack in a rolling way. The gravity balance device comprises a guy rope and a coil spring. The guy rope is connected with the coil spring, bypasses the roller and is connected with the sliding panel. The coil spring is rotatably connected with the bracket. The invention provides the elevator mechanism with compact structure, low cost and better stability.

Description

technical field [0001] The invention relates to a lifting mechanism, in particular to a lifting mechanism of a liquid crystal display. Background technique [0002] Compared with CRT (Cathode Ray Tube, cathode ray tube) displays, liquid crystal display devices have the advantages of small size and light weight, and now they have gradually replaced traditional CRT displays and become mainstream products in the market. However, in the existing liquid crystal display lifting mechanisms, most of them realize the lifting function with a slide rail structure. [0003] Such as figure 1 As shown, a conventional lifting mechanism for adjusting the height of a liquid crystal display includes: a lifting seat 5 , a lifting block 6 and a coil spring 7 . A groove 51 is defined on the lifting base 5 , and two opposite sliding rails 52 are arranged in the groove 51 , and a fixing hole 53 is formed on the top of the outer edge of the groove 51 . The lifting block 6 is accommodated in the ...
