Abstract

The utility model relates to a hidden spring glasses frame improved structure, particularly a structure of glasses leg. A hinge cuboid thereof is arranged in the parallel lead rails; one end of the parallel lead rail bunts a spring; the front end of an adjustable screw is screwed with the hinge after penetrated by the other end of the spring to enable the spring to be compressed between the parallel lead rails and the adjustable screw. The components are put into a housing of the glasses leg. When the glasses leg is pulled open exceeding 90 DEG, the glasses leg is avoided being broken or glasses deformation owing to the effect of the spring to achieve the effect on protecting glasses, and one other replaceable hinge can be used with different hinge types.

Description

Hidden spring glasses frame improved structure

The utility model relates to a kind of improvement structure of concealed spring earpiece, is applicable on the spectacle frame of various materials, because the effect of spring, earpiece is pulled open surpass 90 degree and the unlikely earpiece or make the glasses distortion of fractureing.

General glasses have suitable tightness, earpiece to pull open when wearing for keeping all to be no more than usually 90 degree, but because the wearer often only holds an earpiece with one hand takes off or put on one's glasses, and day long-pending cause glasses to be out of shape, to focus inaccurate and affect one's power of vision with tired; Though the appearance of existing spring earpiece, so ideal is not attained in its structural design, manufacturing as yet.Habitual Glass spring earpiece is that spring 3A is placed on the spring base 21A as illustrated in fig. 1 and 2, and combined hinge 1A and slide block 2A insert fixing pin 4A and prevent to separate when hinge 1A from sliding with slide block then, and said structure has following shortcoming:

1, in order to make the slip about having only between combination back hinge 1A and slide block 2A, and can dandle or have before and after the situation of displacement take place, slide rail 12A and chute 22A need have high precision, could driving fit during combination, and it is complex-shaped, the manufacturing cost height.

2, spring base 21A is formed by milling, increases processing cost.

3, need first compression spring 3A could insert fixed pin 4A, spring base 21A becomes closed during combination, and compression spring is difficult for, and causes combination difficulty height.

4, with welding manner and earpiece combination, so only be applicable to the earpiece of metal material, the scope of application is wideless.

Fundamental purpose of the present utility model is to overcome the above-mentioned defective of prior art and improvement structure that a kind of concealed spring earpiece is provided, avoids the person's of wearing glasses improper use to cause the glasses distortion and affects one's power of vision.

Secondary objective of the present utility model is to provide a kind of improvement structure of concealed spring earpiece, and it can be applied on the materials such as metal, plastic cement, carbon fiber, nylon, and the scope of application is extensive.

A purpose more of the present utility model is to provide a kind of improvement structure of concealed spring earpiece, and it can utilize automatization high speed production to reduce cost, and cost is about 1/5 to 1/10 of habitual product.

Another purpose of the present utility model is to provide a kind of improvement structure of concealed spring earpiece, and its member is simple, assembling is simple and maintenance is easy.

Realize the improvement structure of a kind of concealed spring earpiece of the present utility model, it comprises:

One hinge, one end are circular-arc and a circular hole are arranged that the other end extends to rectangular parallelepiped; One closed slide becomes the hollow tetrahedron of both ends open, but is opening simultaneously wherein; One spring; One adjusts screw; One shell becomes the hollow form of an end opening, in guide groove is arranged, opening part outwards protrudes a catch; One earpiece;

Wherein, hinge rectangular parallelepiped part is inserted in the closed slide by an end, the closed slide other end props up spring, adjusting screw penetrates in the spring, and its front end screws in hinged base is compressed spring, combinations thereof is inserted the shell hollow bulb, and make closed slide and shell combination, with the shell other end and earpiece combination;

By the assembling of said structure, make earpiece produce the effect that can outwards pull open an angle again, and the protective spectacles pin is not fractureed, the unlikely distortion of glasses.

Hinge can be the hinge of another replaceable use, and the top of its circular-arc end and front end respectively are a recess, and the other end is a rectangular parallelepiped.

Now be described as follows with regard to detailed content conjunction with figs. of the present utility model, figure number:

Fig. 1 is the assembled sectional view of habitual product.

Fig. 2 is the exploded view of habitual product.

Fig. 3 is a constitutional diagram of the present utility model.

Fig. 4 is an exploded view of the present utility model.

Fig. 5 is an assembled sectional view of the present utility model.

Fig. 6 is an embodiment cut-open view of the present utility model.

The utility model (referring to Fig. 4) comprising: one is placed in closed slide 2, on hinge 1 rectangular parallelepiped passes the adjustment screw 4 that a spring 3 and hinge 1 screw togather, and said elements is placed shell 5 in it, shell 5 and earpiece 7 combinations; Wherein, one of 1 one-tenth on hinge is circular-arc, and end has a pan 11, is used for the hinge combination with spectacle-frame, and an end that extends to rectangular parallelepiped has one to support protruding 13 and prop up the closed slide 2 that is placed on the hinge 1, and the rectangular parallelepiped bottom is provided with a screw 12; Be placed in the JiongZi Xing of the closed slide 2 formation openings at one side on the hinge 1, its end face is provided with a fixing threaded hole 21, closed slide 2 one ends prop up spring 3, adjusting screw 4 goes here and there in the middle of spring 3, screw 12 spiral shells of its front end and hinge 1 bottom and and be threaded to suitable tightness, make spring 3 at closed slide 2 with adjust 4 on screw by compression; The hollow form of 5 one-tenth one end openings of shell, the combinations thereof part is placed shell 5 inside, there are guide groove 52 guiding closed slides 2 to insert in the shell 5, fixed screw 6 passes taper hole 51 on the shell 5 and the fixing threaded hole 21 of closed slide 2 screws togather, make closed slide 2 and shell 5 combinations, shell 5 opening part front ends have the catch 53 of protrusion, prop up spectacle-frame when earpiece is pulled open and form a fixing subtended angle, the earpiece 7 of shell 5 can be used plastic material one injection molding, or earpiece 7 make with metal after again with shell 5 combinations of injection molding.Other has one can replace the hinge 8 that uses with hinge 1, and there is a recess 81 hinge 8 circular top top, and is preceding and another recess 82 arranged.

When generally wearing glasses, because catch 53 props up spectacle-frame (referring to Fig. 5), make the open fixed angle of spectacle-frame, when pulling outward again (referring to Fig. 6), be to be that the center of circle rotates with the point that catch 53 and spectacle-frame join, when earpiece rotates and the closed slide 2 of shell 5 combinations on hinge 1, slide, and compression spring 3, till maximum can pull open and be compressed fully to spring 3, decontrol the back because the elastic force of spring 3 makes the earpiece reinstatement, so can reach earpiece and do not fractureed the effect of the unlikely distortion of glasses.

In sum, the utility model can be used for all kinds of ocular lens materials such as metal, plastic cement, carbon fiber, and its scope of application is extensive, and can avoid glasses distortion and affect one's power of vision, and has practicality.
