Abstract

The utility model relates to an elastic eyeglass rack which comprises an eyeglass frame, eyeglass legs and an elastic hinge shaft core, wherein the eyeglass frame and the eyeglass legs are movably connected into integration, the eyeglass frame and the end part of one of the eyeglass legs are in main hinge-shaped structure, the end part of the other one of the eyeglass legs is provided with a containing hole matched with the elastic hinge shaft core which is clamped in the containing hole, the head of the elastic hinge shaft core is in auxiliary hinge-shaped structure connected with a main hinge and is hinged with the main hinge, the end part of the auxiliary hinge-shaped structure of the head of the elastic hinge shaft core is provided with a butting surface, the main hinge-shaped structure is correspondingly provided with a butting surface, and the butting surfaces are butted when the eyeglass frame and the eyeglass legs are mutually retracted. When the eyeglass frame and the eyeglass legs are retracted and are mutually rotated to a full folding position, the butting surfaces of the auxiliary hinge-shaped structure and the main hinge-shaped structure of the head of the elastic hinge shaft core are mutually and just opposite and are butted for preventing a condition that the outside edges of the end parts of the eyeglass frame and the eyeglass legs are crashed to abrade the outer surface of the eyeglass frame to affect the appearance of the utility model. In addition, the central lines of retracting positions between the eyeglass frame and the eyeglass legs can be ensured to be mutually vertical after the utility model is retracted.

Description

Elastic spectacle frame

Technical field

The utility model relates to a kind of component parts of glasses, particularly a kind of elastic spectacle frame that adopts elastic hinge to connect.

Background technology

As everyone knows, glasses are commodity indispensable during people live, and along with progress of science and technology, people are also more and more higher to the requirement of glasses, Just because of this, glasses manufacturer and deviser all keep on improving to each component parts of glasses, to make it to wear more comfortable and convenience.

In the prior art, to shown in Figure 2, the folding position of spectacle frame is just at the coupling arrangement of picture frame 1 with the junction setting of mirror leg 2 as Fig. 1, use various elastic hinges mostly, make picture frame 1 and mirror leg 2 form flexible flexible connection, that is to say, during 2 one-tenth open modes of picture frame 1 and mirror leg, both connect by elastic hinge because of it, still but elastic range is in fine setting, makes to wear more comfortablely, and the elastic force of spring hinge also can help the folding gathering action of picture frame 1 and mirror leg 2.

But, because in the use of glasses, picture frame 1 and mirror leg 2 are opened many times and are drawn in, and when drawing in, shown in the dotted line among Fig. 1 and Fig. 2, usually because the inertia of elastic force, make the engagement edge place, the outside of picture frame and mirror leg end, promptly collision mutually takes place in the position of C shown in the figure, easy to wear, the exterior appearance of destruction spectacle frame.

In addition, most glasses manufacturer, particularly in the production of high-quality glasses, require mirror leg 2 vertical mutually with picture frame 1 its gathering position when drawing in, just its center line (among the figure shown in the dot-and-dash line) that draws the position in becomes 90 degree, there is no the vertical accurate realization that the specific structure of design guarantees to draw in the position on the existing spectacle frame, the general size that just adopts part cooperates and realizes, and the tolerance of industrial mass production, usually make that the center line that draws the position in is difficult to accurately become 90 degree, can be described as and be difficult to realize.

In summary, the glasses frame elastic hinge of described prior art on reality is used, obviously exists inconvenience and defective, so be necessary to be improved.

Summary of the invention

The purpose of this utility model provides a kind of picture frame and mirror leg when drawing in, and the sub-hinge of head of the axle core of elastic hinge forms conflict with the centre drawer hinge structure, and the outer ledge that prevents picture frame and mirror leg bumps and guarantees to draw in the orthogonal elastic spectacle frame in position.

To achieve the above object, the technical solution of the utility model is as follows:

A kind of elastic spectacle frame comprises picture frame, mirror leg at least and picture frame, mirror leg is flexibly connected all-in-one-piece elastic hinge axle core; Described picture frame becomes centre drawer hinge shape structure with one end in the mirror leg, another end is provided with the containing hole that matches with this elastic hinge axle core, this elastic hinge axle core is installed in this containing hole, and its head is the sub-hinge shape structure that is connected with described centre drawer hinge and hinged with this centre drawer hinge; The end of the sub-hinge arrangement of described axle core head is provided with a conflict face, and described centre drawer hinge structure correspondence also is provided with a conflict face, and these conflict faces form when picture frame and mirror leg draw in mutually and conflict.

Described elastic spectacle frame, wherein, the end of described centre drawer hinge structure is provided with a storage tank and inserts also the rotation mutually of generation therein for sub-hinge, conflict face corresponding to sub-hinge end section on the bottom land wall of this storage tank also is provided with conflict face, and when mirror leg and picture frame drew in fully, this two conflict face forms conflicted.

Described elastic spectacle frame, wherein, described conflict face is the plane.

Owing to adopt above-mentioned structure, picture frame and mirror leg draw in, when turning to complete folding position mutually, the conflict face of the sub-hinge of head and the centre drawer hinge structure of the axle core of elastic hinge mutually over against and form conflict, the end outer ledge that prevents picture frame and mirror leg bumps and the outside surface of the spectacle frame that weares and teares causes influencing attractive in appearance.

And when complete folding position, the sub-hinge of head of the axle core of elastic hinge and the conflict face of centre drawer hinge structure are conflicted over against also forming mutually, can guarantee that after gathering the center line at the gathering position of picture frame and mirror leg is vertical mutually, and may command mirror leg can not collide eyeglass after gathering.
