Hinge mechanism

Abstract

This invention is hinge device, which includes fixing element, rotating element and pivot rotating assembly. The rotating element and fixing element are connected through pivot rotating assembly. The rotating element is arranged with lateral plate, on which has deformed hole. The fixing element has the seat, on which has pivot hole and spacing groove. The spacing groove is adjacent to the pivot hole and communicated to one side of pivot hole. The pivot rotating assembly is composed of pivot, elastic element and locking element. The pivot is arranged with deformed shaft part matching the deformed hole of rotating element and the spacing element. The pivot passes through the lateral plate deformed hole of rotating element and seat pivot hole of fixing element. The locking element is fixed on one end of pivot. The elastic element, which generates torsion force when rotating element rotates relative to fixing element, is covered on pivot and clamped between rotating element and fixing element. The spacing element, which limits rotating element to rotate between first and second limiting positions, is set in the said spacing groove. This invention has good spacing effect and stability.

Description

Technical field [0001] The invention relates to a hinge structure, in particular to a hinge structure for liquid crystal displays. Background technique [0002] With the widespread application and development of computers, monitors used with them tend to be thinner and lighter. The traditional display is a Cathode Ray Tube (CRT), which is not only large in size but also quite heavy. The liquid crystal display has the advantages of small size, light weight, high definition and low radiation, and is widely accepted by the market. In addition, in order to increase the convenience of use of the liquid crystal display, it is often necessary to rotate or swing its screen to a certain angle. [0003] The rotation or swing function of the liquid crystal display is usually realized by a hinge structure. For example, an existing hinge structure includes: a fixing piece, a pivot, a number of gaskets containing oil holes, and a fixing assembly; the fixing piece is bent into an L-shaped plate...

AI Technical Summary

Problems solved by technology

The hinge structure limits the rotation angle of the LCD screen through the special-shaped limiting hole. However, the hinge structure requires high manufacturing precision for the special-shaped limiting hole, and the limiting hole is easy to wear, so its limiting effect and stability are poor.
