Abstract

The invention relates to a spectacles structure, in particular to a spring hinge for spectacles, which consists of a bird's head, a housing, a spring core assembly, and screws connecting the bird's head and the spring core assembly. The spring core assembly is composed of a mandrel with a plug at one end, a spring set on the mandrel, a slider threaded on the mandrel, and a single tooth core body inserted into the mandrel. Described single tooth core body and slide block all are a cross section and are square cubes, and the top of single tooth core body is a semicircular flat body, namely single tooth, and it is horizontally provided with through hole, and its transverse hole is used for single tooth When the core body and the bird head are hinged, the screw passes through; the bottom end of the lower half is an inclined plane, and a blind hole for inserting the mandrel is arranged on the inclined plane along the axial direction of the rectangular cylinder. The upper end surface of the slider is an inclined plane, and a long through hole for inserting the mandrel is arranged in the axial direction. The casing and the temples form a cavity for the spring core assembly to be placed in, and a groove or a protrusion for the slider to be caught.

Description

technical field [0001] The invention relates to a spectacles structure, in particular to a spring hinge for spectacles. Background technique [0002] Chinese patent CN96192848.4 discloses "a spring hinge for glasses and a manufacturing method thereof". Its purpose is to provide a spring hinge with simple structure and low manufacturing cost and its manufacturing method, in particular to provide a spring hinge for spectacles with a middle piece and two spectacle legs hinged to it. Wherein, the spring hinge includes a spring housing corresponding to the temple of the glasses and an intermediate hinge member cooperating with the spring housing, the intermediate member is fixed on the intermediate hinge member, and the spring housing has a The body extends longitudinally and has a continuous through inner wall; the spring housing can be pressed into the range of the annular groove of the locking ring supported by the groove as the locking body, so that the locking ring is fixed...
