Abstract

The utility model relates to the spectacle field, which discloses frameless spectacles. Primary fixing columns and secondary fixing columns of existing spectacles penetrate through lens, the secondary fixing columns penetrate through hemispherical secondary fixing grooves at the edges of the lenses, and inner spherical surfaces of the lenses are rough and unattractive. The hemispherical fixing grooves are easy to be broken and glass fragments are easy to hurt eyes of people. Further, convex secondary fixing columns are easy to form sanitary dead angles and affects beauty level of the spectacles. The depth of the secondary fixing groove of the frameless spectacles is half of that of the lens, thereby resolving the above problems of the existing spectacles.

Description

A kind of no-frame glasses

Technical field

The utility model relates to a kind of glasses, relates in particular to a kind of no-frame glasses.

Background technology

Glasses are essential articles for use of dysphotia person, also are fashion accessories, use very extensive.Authority's enquiry data shows: at present, China's adolescent myopia incidence of disease accounts for 33% of world A nearsighted person sum up to 50%-60%, accounts for the ratio of world population sum 22% far above China; The amblyopia incidence of disease is 2%-4%, and the low eyesight incidence of disease is 1%-2%, about 800,000,000 people of the number that existing China wears glasses.

Existing glasses have patterns such as full frame, half frame, no frame.No-frame glasses meet the design concept of brief group from seeming fairly simple in appearance, also are welcomed by users.But the spoilage of no-frame glasses is higher than full frame and no-frame glasses far away, practicality is not high, therefore with regard to the practicality aspect of no-frame glasses, no-frame glasses can be accepted and welcome by more consumers, just must be innovated and improve the steadiness of no-frame glasses and applicability.

The main fixed leg of existing no-frame glasses and secondary fixed leg all are to connect eyeglass, and secondary fixed leg passes the semi-circular secondary pickup groove of lens edge, and the Internal Spherical Surface of eyeglass is more coarse, and is attractive in appearance inadequately.Semi-circular secondary pickup groove is broken easily, and glass fragment jeopardizes the safety of eyes easily.The secondary fixed leg of projection forms the corner or spot as yet untouched by a clean-up campaign easily, influences attractive in appearance.

The utility model content

The technical problems to be solved in the utility model is the improvement by structure, has both guaranteed the steadiness of no-frame glasses, guarantees the attractive in appearance of eyeglass Internal Spherical Surface again, reduces the corner or spot as yet untouched by a clean-up campaign, improves the safety coefficient of glasses.

For solving above technical matters, the utility model is made into secondary pickup groove by the half slot that connects eyeglass, and the degree of depth is half a semi-circular groove of lens thickness, and the length of secondary fixed leg also shortens accordingly.No-frame glasses after the improvement comprise left mirror pin, the bridge of the nose, nose holder, eyeglass, right mirror pin.The two ends of the bridge of the nose are respectively equipped with main fixed leg and secondary fixed leg, and main fixed leg is a double-screw bolt, pass the main fixed orifice of eyeglass, use nut lock; Secondary fixed leg is stuck in the secondary pickup groove of eyeglass for highly approximating half cylinder of lens thickness; Distance between main fixed leg and the secondary fixed leg equals the distance between main fixed orifice and the secondary pickup groove.Every eyeglass is provided with two main fixed orifices and two secondary pickup grooves.Two secondary pickup grooves place the edge, the left and right sides of eyeglass respectively, for the degree of depth equals half half slot of lens thickness.Main fixed orifice places the same horizontal line of secondary pickup groove, the inboard of eyeglass, for running through the circular hole of eyeglass.The nose holder is installed on the bridge of the nose.Left side mirror pin is installed on the eyeglass on the left side, and right mirror pin is installed on the eyeglass on the right, and mounting means is the same with the mounting means of the bridge of the nose, all is to be installed in respectively on the main fixed orifice and secondary pickup groove of eyeglass by main fixed leg and secondary fixed leg.

Because the degree of depth of secondary pickup groove equals lens thickness half, does not run through eyeglass, so lens surface cleans easily, can not stay the corner or spot as yet untouched by a clean-up campaign; The Internal Spherical Surface of eyeglass is smooth, in case the eyeglass fragmentation, fragment can not fly inside, has guaranteed the safety of eyes, has improved the safety coefficient of glasses.

Embodiment

Fig. 1 is the structural representation of the utility model no-frame glasses.

Fig. 2 is the front view of the eyeglass of the utility model no-frame glasses.

As shown in the figure, the utility model no-frame glasses comprise left mirror pin 2, the bridge of the nose 1, nose holder 4, eyeglass 3, right mirror pin 5.The two ends of the bridge of the nose 1 are respectively equipped with main fixed leg and secondary fixed leg, and main fixed leg is a double-screw bolt, pass the main fixed orifice 31 of eyeglass 3, use nut lock; Secondary fixed leg is stuck in the secondary pickup groove 32 of eyeglass 3 for highly approximating half cylinder of eyeglass 3 thickness; Distance between main fixed leg and the secondary fixed leg equals the distance between main fixed orifice 31 and the secondary pickup groove 32.Every eyeglass 3 is provided with two main fixed orifices 31 and two secondary pickup grooves 32.Two secondary pickup grooves 32 place the edge, the left and right sides of eyeglass 3 respectively, for the degree of depth equals half half slot of eyeglass 3 thickness.Main fixed orifice 31 places the same horizontal line of secondary pickup groove 32, the inboard of eyeglass 3, for running through the circular hole of eyeglass 3.Nose holder 4 is installed on the bridge of the nose 1.Left side mirror pin 2 is installed on the eyeglass 3 on the left side, and right mirror pin 5 is installed on the eyeglass 3 on the right, and mounting means is the same with the mounting means of the bridge of the nose 1, all is to be installed in respectively on the main fixed orifice 31 and secondary pickup groove 32 of eyeglass 3 by main fixed leg and secondary fixed leg.

Claims

1, a kind of no-frame glasses, comprise left mirror pin, the bridge of the nose, nose holder, eyeglass, right mirror pin, it is characterized in that: described eyeglass is provided with secondary pickup groove (32), the degree of depth of secondary pickup groove (32) equals half of lens thickness, is equipped with secondary fixed leg on described left mirror pin, right mirror pin and the bridge of the nose and is stuck in the secondary pickup groove (32).
