The utility model discloses, when the installation of elbow and lens, can set up two through-holes on the lens, the interference fit installation is adopted with the structural both sides limit of taking the barb alveolus of U type to two through-holes, and the position that links to each other with two through-holes on the lens still is provided with the counter bore, and the setting of counter bore can let whole U type structure inlay in the lens and do not pass the lens, improves the area of contact that the lens is connected, increases joint strength.
Description
Technical Field
The utility model relates to a resin glasses processing field especially relates to a fixed elbow of frameless glasses lens that lens material is resin, PC or ya keli material.
Background
The frameless glasses generally comprise lenses, a middle beam, an elbow and glasses legs, and the lenses, the middle beam, the elbow and the glasses legs are not fixed by fish wires, so that the frameless glasses are attractive in appearance, but how to ensure that the left and right lenses are well fixed, small shaking exists between the left and right lenses, the relative requirements on the structures of the middle beam and the elbow are higher, the lenses are generally punched at present, threaded rods are reserved on the middle beam and the elbow, and the rimless glasses are installed in a nut fixing mode. However, in general, a gap is formed between the threaded rod and the lens hole, and once the nut is loosened, the whole glasses are easy to displace, so that the use of a wearer is affected.
Disclosure of Invention
To the above problem, an object of the utility model is to provide a fixed elbow of frameless glasses lens, through U type structure and barb alveolus structure of setting on the elbow, can increase the area of contact with the lens when the installation, improve locking not hard up ability.
The technical scheme of the utility model is realized through following mode: the utility model provides a fixed elbow of frameless glasses lens comprises elbow main part, mirror leg connecting portion, lens connecting portion, mirror leg connecting portion set up the afterbody in the elbow main part, mirror leg connecting portion on be provided with the circular through-hole of being connected with the mirror leg, lens connecting portion set up the afterbody inboard in the elbow main part, mirror leg connecting portion and lens connecting portion make its characterized in that by the metal material: the lens connecting part is of a U-shaped structure.
The U-shaped structure of the lens connecting part is provided with barb tooth socket structures which are uniformly distributed.
The top of the left side and the top of the right side of the U-shaped structure of the lens connecting part are provided with sharp tops, and the tops of the sharp tops are subjected to arc transition treatment.
The barb alveolus structure the higher authority be circular arc transition surface, the lower authority be the straight flange, the straight flange is 75 degrees ~82 degrees with the contained angle of vertical direction.
The horizontal height of the upper surface of the inner side of the U-shaped structure of the lens connecting part is greater than the horizontal height of the upper surface of the elbow main body and the lens connecting part.
The utility model discloses, when the installation of elbow and lens, can set up two through-holes on the lens, the interference fit installation is adopted with the structural both sides limit of taking the barb alveolus of U type to two through-holes, and the position that links to each other with two through-holes on the lens still is provided with the counter bore, and the setting of counter bore can let whole U type structure inlay in the lens and do not pass the lens, improves the area of contact that the lens is connected, increases joint strength.
Drawings
Fig. 1 is a front view of a fixed elbow for a rimless spectacle lens of the present invention;
fig. 2 is a schematic view of the elbow and the lens of the present invention.
In the figure: 1 elbow main part, 2 mirror leg connecting portion, 3 lens connecting portion, 4 lenses.
Detailed Description
As shown in figure 1, the schematic view of the frameless spectacle lens fixing elbow of the utility model comprises an elbow main body 1, a glasses leg connecting part 2 and a lens connecting part 3, wherein the glasses leg connecting part 2 is arranged at the tail part of the elbow main body 1, the glasses leg connecting part 2 is provided with a circular through hole 2-1 connected with a glasses leg, the lens connecting part 3 is arranged at the inner side of the tail part of the elbow main body 1, the glasses leg connecting part 2 and the lens connecting part 3 are all made of metal materials, the lens connecting part 3 is of a U-shaped structure, the U-shaped structure of the lens connecting part 3 is provided with barb tooth groove structures 3-1 which are uniformly distributed, the tops of the left side and the right side of the U-shaped structure of the lens connecting part 3 are provided with sharp tops 3-2, the tops of the sharp tops 3-2 adopt circular arc transition treatment, the barb tooth socket structure 3-1 is characterized in that the upper side is an arc transition surface, the lower side is a straight edge, an included angle A between the straight edge and the vertical direction is 75-82 degrees, and the horizontal height of the upper surface 3-3 on the inner side of the U-shaped structure of the lens connecting part 3 is larger than the horizontal height of the upper surface 1-1 of the connecting part of the elbow main body 1 and the lens 4.
As shown in figure 2, the elbow and the lens are fixed schematically, because the level height of the upper surface 3-3 on the inner side of the U-shaped structure of the lens connecting part 3 is greater than the level height of the upper surface of the connecting part of the elbow main body 1 and the lens 4, when the elbow connecting part 3 and the lens 4 are installed, two through holes 4-1 can be arranged on the lens 4, the two through holes 4-1 and two side edges of the barbed tooth groove 3-1 on the U-shaped structure are installed in an interference fit manner, a counter bore 4-2 is also arranged at the position on the lens 4 connected with the two through holes 4-1, the arrangement of the counter bore 4-2 can enable the whole U-shaped structure to be embedded in the lens 4 without passing through the lens 4, the contact area of the lens 4 is increased, and.
