Problems solved by technology

But adopting brazing in the spring hinge structure of the prior art can encounter such problems: because the temperature of brazing is higher, the area of ​​welding is the connecting surface of the whole housing, so high temperature has great influence on the performance of parts pre-installed in the housing. will have a big impact
[0007] With the improvement of people's consumption level and living standard, the requirements for the materials of spectacle frames and accessories are getting higher and higher. In the past, the hinges and their butt joints

Abstract

A spring hinge structure of spectacle frame, which contains a spring box, a joint held in spring box extending one end, at least a spring held in box, and a package element, said hinge structure can reducing the size of hinge, each element is respectively assembling without machine. Said invention can prevent the liquid plastics or solution permeating into spring box in injection moulding, friction in material, so to raise performance of spectacle frame.

Description

technical field [0001] The invention relates to a spring hinge structure, in particular to a spectacle frame spring hinge structure for connecting spectacle legs and spectacle frames. Background technique [0002] The spring hinge structure of the spectacle frame is usually used to rotatably connect the spectacle legs and the spectacle frame, so that when the spectacle legs are not in use, the spectacle legs can be rotated to be folded into the spectacle frame, thereby facilitating the storage and carrying of the spectacle glasses, and can be used when wearing the spectacle glasses. The temples of the glasses are elastically opened to the outside, so that it is convenient and comfortable to wear the glasses. [0003] International Patent Application No. WO97 / 41482 discloses a spring hinge structure for a spectacle frame, as shown in Figure 1, which includes a box body 100, a T-shaped pull rod 110 housed in the box body, and two springs 120 respectively located on both sides ...
