Abstract

The utility model discloses an elastic structure for spectacle frame legs, which belongs to the field of the spectacle, and has simple structure, can make the spectacle frame legs have elasticity, and can be better fixed when in use. The elastic structure is provided with a first part which is fixedly provided with a second part, a cam rotating shaft is fixed on the second part and is provided with a third part which is provided with an elastic piece, and the arc part of the elastic piece is assembled on the cam rotating shaft to form a free-rotating structure. The utility model has novel design, makes the wearer feel comfortable and stable when wearing the spectacle, and is applicable to the field of the spectacle.

Description

A kind of elastic construction of eyeglasses frame leg

Technical field

The utility model relates to a kind of eyeglasses frame, more specifically, relates to a kind of elastic construction of eyeglasses frame leg.

Background technology

In the prior art, the structure of eyeglasses frame is comparatively single, in order to improve comfort level that people wear glasses and glasses better to be fixed in wearer's cheek, the common position of amounting at glasses, just elastic device is set in the junction of spectacle-frame and mirror holder leg, now general use mostly be various catapult hinges, structure is complicated, produce and assembling and maintenance comparatively loaded down with trivial details; The existing technological deficiency of eyeglasses frame in the present technology; Become those skilled in the art anxious technical matters to be solved.

Summary of the invention

Technical purpose of the present utility model is to overcome in the prior art, the comparatively loaded down with trivial details technical matters of elastic construction production, assembling and maintenance of eyeglasses frame leg; Provide a kind of rational in infrastructure, make the eyeglasses frame leg that certain elasticity be arranged, more comfortable during use, the elastic construction of the eyeglasses frame leg that can better fix.

For realizing above technical purpose, the technical solution of the utility model is:

A kind of elastic construction of eyeglasses frame leg, described elastic construction is provided with first parts, is fixed with second parts on described first parts, on described second parts, be fixed with a cam shaft, the curved portions that flexure strip on the 3rd parts is set on the described cam shaft forms rotational structure.

Further, the flexure strip of described the 3rd parts is located in the middle of the 3rd parts and with the both sides of the 3rd parts and is separated.

In the utility model, first parts are fixed on the picture frame of glasses, space when vacateing elastic stage for the 3rd parts, second parts are fixed in a side of first parts and extend, be provided with a cam shaft at extended spot, and the 3rd parts are provided with flexure strip, and the curved portions of flexure strip is assemblied on the cam shaft on second parts, forms free rotational structure.

Useful technique effect of the present utility model is, adopted a structure cleverly, constitutes the elastic construction on the eyeglasses frame leg, and is more comfortable and firm when making wearing spectacles; The utility model is simple in structure, design is ingenious, with low cost, easy to implement.

Fig. 4 is among embodiment of the utility model, the structural representation of the 3rd parts and flexure strip thereof.

Fig. 5 is among embodiment of the utility model, the flexure strip of the 3rd parts be located in the middle of the 3rd parts and with the both sides separated structures synoptic diagram of the 3rd parts.

Embodiment

Following structure accompanying drawing describes embodiment of the present utility model in detail, but claim of the present utility model is not done any qualification.

In conjunction with Fig. 1 to Fig. 5; In the elastic construction of the utility model eyeglasses frame leg, on described elastic construction, be provided with first parts 1, be fixed with second parts 2 on described first parts 1, on described second parts 2, be fixed with a cam shaft 20, on the described cam shaft 20, be equipped with the curved portions of flexure strip 31 on the 3rd parts 3.

In use of the present utility model, one end of first parts 1 is fixed on the lens frame of glasses, mobile space when vacateing elastic stage for spending for third angle 3, second parts 2 are fixed in a side of first parts 1 and extend, be provided with a cam shaft 20 at extended spot, and the 3rd parts 3 are provided with flexure strip 31, and the curved portions of flexure strip 31 is assemblied on the cam shaft 20 on second parts 2, forms free rotational structure; In embodiment of the present utility model, flexure strip 31 can be that a side of being located at the 3rd parts 3 forms fixed sturcture.As shown in Figure 4, also can be to be located in the middle of the plane of the 3rd parts 3 and to separate with the both sides of the 3rd parts.In Fig. 2, when the 3rd parts 3 during to lopsidedness, flexure strip 31 just produces a restorable elastic force, and the mirror holder leg is clamped on the cheek.

In a word, the utility model is simple in structure, design is ingenious, with low cost, easy to implement, and is more firm and comfortable when the user wears, and is a not only practical but also novel technological improvement of this area.
