Abstract

A special hinge for injection-molded spectacle frames includes two hinge components hinged mutually. Free ends of the two hinge components are correspondingly connected to a frame and a temple respectively, the free end of each hinge component is a U-shaped double-layer open structure, the corresponding connection end-face of the frame or the temple is provided with a slot, and the free ends of the hinge components are correspondingly engaged with the slots in an inserted-connection way. The special hinge has smart design and reasonable structure, the position of the slots for the frames and the temples can be accurately set during injection molding, the hinge component is inserted for tight connection after production of injection molding parts, which guarantees precise positioning and quick and convenient assembly without adjustment pair by pair, additionally the hinge can be assembled after all the components as the frames, temples and the like are painted and colored, thereby the coloring quality is fine while the appearance of the whole spectacle frames is beautiful, and the paint on the special hinge can not be easily peeled due to the rotation of the hinge during using, thereby greatly increasing the quality of the products.

Description

Special hinge for injection-molded spectacle frame

Technical field:

The utility model relates to hinge special-purpose in the hinge that a kind of spectacle frame is used, particularly injection-molded spectacle frame.

Background technology:

The picture frame of injection-molded spectacle frame all is to be connected by hinge through with the mirror pin, the hinge member of general hinge all is to be embedded in the moulding to fix, must in the spectacle frame injection moulding process, just hinge member be fixed on corresponding picture frame and mirror foot position, the rigging position of hinge obviously can not be very accurate like this, the also excessive easily limit of moulding, generally also must adjust by secondary, the requirement of assembling is improved, production efficiency reduces.And this connected mode of existing hinge can only be after assembling be finished, again to whole spectacle frame together with the hinge colouring of spraying paint, operation is inconvenient, has influenced controllable quality.In use, the rotation repeatedly of hinge also will inevitably produce depainting phenomenon, makes spectacle frame look very old, has influenced the attractive in appearance of whole glasses, has reduced the class of product.

Summary of the invention:

At the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, and assembling and positioning is special hinge for injection-molded spectacle frame accurately and conveniently.

The utility model comprises two hinge members that are hinged, the free end of two hinge members correspondence respectively is connected on picture frame and the mirror pin, the free end of each hinge member is the double-deck uncovered structure of U type, be equipped with slot on the corresponding connection end face of picture frame or mirror pin, the free end of hinge member is then corresponding to plug together close-fitting with slot and is connected.

Hinge member deft design of the present utility model, rational in infrastructure, picture frame and mirror pin can accurately be set the position of slot in injection moulding is produced, hinge member inserts close-fitting again and connects after moulding production, it is very accurate to locate, and assembling is convenient rapidly, need not to adjust by secondary.And, can after all spraying paint colouring, parts such as picture frame, mirror pin refill the align reaming chain, and not only tinctorial quality is good, and glasses integral body specious in use also can depainting phenomenon not occur because of hinge through, and the class of product increases substantially.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings:

Fig. 1 is the main structure synoptic diagram of embodiment;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the assembly structure synoptic diagram of embodiment;

Fig. 4 is that the A-A of Fig. 3 analyses and observe enlarged diagram.

Embodiment:

As shown in the figure, the free end of two hinge members that are hinged 1 correspondence respectively is fixedly connected on picture frame 3 and the mirror pin 4, the free end of each hinge member 1 is the double-deck uncovered structure of U type, be equipped with slot 5 on the corresponding connection end face of picture frame 3 or mirror pin 4, the free end of hinge member 1 is then corresponding to plug together close-fitting with slot 5 and is connected.The general connecting hole 2 that on the sidewall of each hinge member 1, also is provided with, 6 of corresponding fasteners are passed connecting hole 2 and are connected picture frame 3 or mirror pin 4, like this after hinge member 1 and slot 5 plug together close-fitting, can utilize securing member 6, as screw, hinge member 1 and corresponding picture frame 3 or mirror pin 4 are tightened, connected more firm.

Present embodiment makes the one deck in the double-deck uncovered structure of the free-ended U type of hinge member 1 plug together slot 5 into picture frame 3 or mirror pin 4, and another layer then exposes, and generally is outer and slot 5 plugs together, and internal layer then is exposed at the surface outward.In the reality,, internal layer or bilayer are all plugged together in the slot 5 according to different designing requirements.
