Embodiment Construction

[0030] like Figure 1-7 As shown, the spring hinge for spectacles in the present invention firstly welds and fixes the track frame 10 on the spectacle leg 1, and then slides and inserts the shell 20 with the coil spring 30 inside the track frame 10, and in front of the shell 20 The structure of the folded portion 40 is bolted.

[0031] The structure of the rail frame 10 of the present invention is: it has a rectangular block shape, and is fixed on the spectacle leg 1 by welding the bottom surface.

[0032] The center portion of both sides of the above rail frame 10 is formed with a step portion 11 in the horizontal direction, which is slidingly combined with the insertion portion 23 formed on both sides of the casing 20 described later. When the rail frame 10 is combined with the casing 20, there will be no Voids, forming a tightly knit structure. Simultaneously, at the front portion of the upper end of the track frame 10, a guide portion 12 in the shape of a rectangular pro...

Abstract

The invention relates to a spring hinge product for spectacles. A track rack bottom is welded and fixed on a spectacle leg. A housing equipped with a coil spring is inserted on the track rack and is connected with a hinge part by a bolt, thus being easy to assemble and disassemble without generating thermal strain of the coil spring and without ultra hinge, and a small volume spring hinge is produced. In the invention, another hinge necessary in prior art is not adopted and the housing directs on the hinge, thus shortening the spring hinge for spectacles to 2.0mm. Simultaneously, only a track rack is welded on the spectacle leg, thus not generating thermal strain of the spring and maintaining original strength of the spring and it is easy torepair and replace after a long term use when the elasticity of the spring is reduced. Additionally, the housing is connected after welding the track rack and the housing completely covers on the track rack, thus avoiding viewing the welding part and achieving the aesthetic effect.

Description

Technical field: [0001] The invention relates to a spring hinge for spectacles. More specifically, after the bottom of the track frame is welded and fixed on the spectacle leg, a shell equipped with a spring is inserted into the track frame, and then bolts are used to connect the hinge. It is easy to assemble and disassemble. , not only does not cause thermal deformation of the coil spring, but also does not require additional hinges, and can be made into a spring hinge for small-sized glasses. Background technique: [0002] Under normal circumstances, the spring hinges for glasses are used on the temples combined with the glasses frames. The elasticity of the glasses legs improves the comfort of wearing glasses and keeps the original shape of the glasses frames. Therefore, the market demand has gradually increased recently. [0003] Along with the increase of market demand, developed the spring hinge for glasses of multiple different forms on the market. But there are some...
