Description

A kind of Combined spectacle frame

Technical field

The utility model belongs to glasses manufacturing technology, is specifically related to a kind of Combined spectacle frame.

Background technology

At present, glasses common on the market only have a mirror holder, the demand that A nearsighted person avoids sunburst to irradiate can not be met, in order to address this problem, the glasses of two-pack mirror holder are disclosed in prior art, the such as patent No. is the modified node method that the Chinese utility model patent of ZL200620139047.7 discloses between a kind of front hanging subframe and main glasses holder, main glasses holder is fastened on mainly through central sill fixture, what this kind of structure mainly adopted is that groove fastens principle with protruding embedded pairing, easily come off when colliding, and clasp can be caused to slide along groove, easily hinder people.

And the patent No. is the utility model patent of ZL201420568423.9, its structure is comparatively complicated, safeguard and use cost higher.

Utility model content

The purpose of this utility model is: mainly overcome existing two-pack mirror holder and there is easy slippage, complex structure, preparation and troublesome maintenance and costly problem.

For this reason, the utility model provides a kind of Combined spectacle frame, the sub glasses holder comprising main glasses holder and be flexibly connected with this main glasses holder, its special character is, the lateral surface of the bridge of the nose support part of described main glasses holder is provided with horizontal two the fixing hangers side by side along described bridge of the nose support part; The medial surface of the overarm of the connection left and right picture frame of described sub glasses holder is provided with the coupling bar that can penetrate described fixing hanger; This coupling bar one end is fixedly connected with this overarm by a vertical described overarm connecting rod;

The other end end of described coupling bar is provided with the scalable and snap close that is that rotate around the length direction of this coupling bar of length direction along this coupling bar;

Described snap close is formed by lock body and from this lock body one end extension to the sleeve of the external screw thread in this lock body;

The opposed end end of the coupling bar relative with lock body is provided with the threaded hole that the periphery caved inward from this opposed end arranges screw thread, extends outward a pitman from the bottom of this threaded hole;

Described pitman one end is fixedly connected with the bottom of described threaded hole, the other end is set in described sleeve, and be hooked on the spacing ring on the inwall being fixed on described sleeve by the annulus of this other end end, with the other end preventing described sleeve from skidding off this pitman;

The length being exposed at the part of described lock body outside described sleeve is greater than the width of described fixing hanger.

The length of described sleeve is 2/3rds of the length of described pitman.

Described lock body is right cylinder or ellipsoid.

Described sleeve and described pitman thread connection.

Described pitman is ring multistage rod.

The utility model has the advantages that: major and minor mirror holder realizes being connected by the simple hanger of structure and coupling bar, easy to use, easy maintenance, low cost, and can not produce longitudinal sliding motion when colliding and damage people.

Below in conjunction with drawings and Examples, the utility model is elaborated.

Embodiment

Easy slippage, complex structure, preparation and troublesome maintenance is there is and costly problem in order to overcome existing two-pack mirror holder, present embodiments provide a kind of Fig. 1, the Combined spectacle frame shown in 2,3, the sub glasses holder 2 comprising main glasses holder 1 and be flexibly connected with this main glasses holder 1, its place being different from existing compound glasses is: the lateral surface of the bridge of the nose support part 3 of described main glasses holder 1 is provided with horizontal two the fixing hangers 4,5 side by side along described bridge of the nose support part 3; The medial surface of the overarm 6 of the connection left and right picture frame of described sub glasses holder 2 is provided with the coupling bar 7 that can penetrate described fixing hanger 4,5; This coupling bar 7 one end is fixedly connected with this overarm 6 by vertical described overarm 6 connecting rod 8.

Composition graphs 4 is visible, and the other end end of coupling bar 7 is provided with the scalable and snap close 9 that is that rotate around the length direction of this coupling bar 7 of length direction along this coupling bar 7; And snap close 9 as shown in Figure 5, form by lock body 10 and from this lock body 10 one end extension to the sleeve 11 of the external screw thread in this lock body 10; The opposed end of the coupling bar 7 relative with lock body 10 is provided with the threaded hole 12 that the periphery caved inward from this opposed end arranges screw thread, a pitman 13 is extended outward from the bottom of this threaded hole 12, pitman 13 one end is fixedly connected with the bottom of described threaded hole 12, the other end is set in described sleeve 11, and be hooked on by the annulus 14 of the other end end of this pitman 13 shown in Fig. 6 outside the spacing ring 15 on the inwall being fixed on described sleeve 11 (right-hand side namely shown in Fig. 6), skid off the other end of this pitman 13 to prevent described sleeve 11; The length being exposed at the part of described lock body 10 outside described sleeve 11 is greater than the width of described fixing hanger 4,5.Fixing hanger can be stuck in the gap between lock body 10 and coupling bar 7 like this, realize clamping, improve the steadiness of the connection of major-minor mirror holder.

Pass through above-described embodiment, easily major and minor mirror holder can be added single hanger by structure to realize being connected with coupling bar, easy to use, easy maintenance, low cost, and can not longitudinal sliding motion be produced when colliding and people be damaged to (probability of lateral impact is less, and after the transverse direction that causes of lateral impact slides, due to the existence of spectacles, play a part barrier, therefore, directly can collide human body to the longitudinal sliding motion of comparing with degree of the probability of the injury that people causes, the injury caused is much smaller).

Less in order to ensure the distance between lock body 10 and coupling bar, the present embodiment is special is 2/3rds of the length of described pitman 13 by the length of sleeve 11.

And in order to the rotation that realizes snap close 9 be convenient to insert in fixing hanger, special lock body 10 to be designed to as right cylinder or ellipsoid.

In order to guarantee the stability between lock body 10 and coupling bar 7 further, sleeve 11 and pitman 13 are designed to thread connection by spy.

And for the ease of realizing the bending effect of lock body 10, special is ring multistage rod by pitman 13, being namely movably hinged by multiple segment is formed, and can realize the bending within the scope of certain angle.
