Background technique

In the past, the traditional image tube display used with general computer equipment has been used in recent years because of its large size, heavy weight, space occupation, and serious radiation problems. It is replaced by liquid crystal displays with advantages such as no radiation, and has become an indispensable and important electronic device for computer equipment.

However, the display itself cannot stand on its own firmly, especially the liquid crystal display. A supporting frame structure must be assembled at the rear side of the liquid crystal display to stand firmly on the desktop. The support frame has changed from the previous fixed height to an adjustable lifting height according to the user's needs, so that the user can adjust to an appropriate viewing height.

Among them, there are many types of support frames for liquid crystal displays, for example: No. TWM256920 (application number: 93201238) patent discloses a coil spring structure of a liquid crystal display lifting seat, which discloses a lifting seat, a lifting block and a coil spring, The lifting block is set in the lifting base and can slide up and down. The coil spring is fixed on the lifting base, one end is wound on a shaft, and the other end is fixed on the lifting base, and the lifting base can be used for fixing the liquid crystal display. .
