Description
Technical field
The invention belongs to glasses manufacturing technology field, relate to a kind of elastic hinge for eyeglasses, particularly a kind of elastic hinge for eyeglasses that can prevent that earpiece from swinging.
Background technology
The glasses of in the past selling on the market, spectacle frame and earpiece mostly adopt the connected mode of hinge screws, this hinged glasses clamping force a little less than, and earpiece open after and the position of spectacle frame fix, earpiece can not be too much rotation, otherwise damage easily.
For the problem that exists, people have made improvement, and earpiece is connected with spectacle frame and is adopted elastic hinge to connect in the existing glasses, and for example the Chinese patent literature data discloses the eyeglasses frame elastic hinge [patent No.: 200820095445.2; Granted publication number: CN201226057Y], it comprises hinge bidentate, slingshot core and catapult box body, slingshot core comprises monodentate core body, keeper and spring, keeper and spring housing are on the monodentate handle of monodentate core body, spring is positioned at after the keeper, and the inner of monodentate handle is provided with one and prevents the flat position that spring comes off; The outer end of monodentate core body and hinge bidentate are flexibly connected, and the keeper of slingshot core and spring are arranged in the catapult box body, and slingshot core is removable by its keeper with the catapult box body and is connected.
But the outer end of the monodentate core body of this kind eyeglasses frame elastic hinge is exposed at outside the catapult box body, only have a part that is connected with the pin thread position to be positioned at the groove of catapult box body, after the installation, the outer end of monodentate core body is positioned between the bidentate of hinge bidentate, if the hinge bidentate is little with the gap that the monodentate core body cooperates, will increase the friction force between hinge bidentate and the monodentate core body, earpiece in moving process, will follow the string or elasticity very weak; If increase the gap that the hinge bidentate cooperates with the monodentate core body, earpiece after the assembling can swing, poor stability, so in process, the tolerance along the diameter of its radial direction of the spacing between the hinge bidentate bidentate and monodentate core body is very high, in the reality batch production, be difficult to control, and processing cost is high.
Summary of the invention
The objective of the invention is for the above-mentioned problems in the prior art, provide a kind of and can prevent that earpiece from swinging, firmly degree is high, the elastic hinge for eyeglasses of good stability.
Purpose of the present invention can realize by following technical proposal: a kind of elastic hinge for eyeglasses, comprise hinge head, spring core and slingshot shell, described spring core is installed in the slingshot shell, it is characterized in that, described slingshot shell has the end of mounting hole one end along at least a slice single tooth in the form of sheets that is axially arranged with of spring core, has at least a slice pin-joint piece in the hinged place of described hinge head, the outer end of described spring core has hinged end and is hinged by bearing pin with the pin-joint piece of above-mentioned hinge head, and the lateral surface of described pin-joint piece fits on the medial surface of above-mentioned single tooth.
Slingshot shell and the earpiece of elastic hinge for eyeglasses are connected, hinge head and spectacle frame are connected, and spring core is installed in the mounting hole in the slingshot shell, spring core be exposed at slingshot shell outer be hinged end, and be hinged by bearing pin with the pin-joint piece of hinge head, the lateral surface of pin-joint piece fits on the medial surface of single tooth, and hinge head and single tooth all are relatively-stationary, though about pull earpiece, the pin-joint piece of hinge head and single tooth block mutually, earpiece can not swing yet, and firmly degree is high, good stability.

The whole hinge hole that is arranged in pin-joint piece and spring core hinged end of bearing pin can not have influence on the bonded to each other of pin-joint piece and single tooth.
In above-mentioned elastic hinge for eyeglasses, has the gap between the hinged end of described spring core and the pin-joint piece of hinge head.
This kind structure makes elastic hinge for eyeglasses when rotating, and does not have friction between hinge head and the spring core, and glasses rotate smooth and easy, and it is little to wear and tear, long service life.
In above-mentioned elastic hinge for eyeglasses, have through hole on single tooth of described at least a slice, described through hole passes for bearing pin.
When using the hinged spring core of bearing pin and pin-joint piece, through hole makes the hinged convenience of spring core and pin-joint piece for passing of bearing pin provides passage.
In above-mentioned elastic hinge for eyeglasses, have breach on single tooth of described at least a slice, described breach passes for bearing pin.
When using the hinged spring core of bearing pin and pin-joint piece, breach makes the hinged convenience of spring core and pin-joint piece for passing of bearing pin provides passage.
In above-mentioned elastic hinge for eyeglasses, the quantity of described single tooth is two, and all has breach on every single tooth, and the both ends of the surface of above-mentioned bearing pin are between two lateral surfaces of two single teeth.
This kind structure, bearing pin can be suitable the lateral surface that stretches out pin-joint piece, can not affect the rotation of elastic hinge for eyeglasses, for attractive in appearance, the both ends of the surface of bearing pin are between two lateral surfaces of two single teeth.
In above-mentioned elastic hinge for eyeglasses, the lateral surface lateral surface corresponding with slingshot shell of the single tooth of a slice in the single tooth of described at least a slice flushes.
Easy to process.
In above-mentioned elastic hinge for eyeglasses, the lateral surface lateral surface corresponding with slingshot shell of two single teeth in the single tooth of described at least a slice flushes.
Two lateral surfaces of two single teeth corresponding with slingshot shell about two lateral surfaces flush respectively, this kind structure, easy to process, profile is consistent, compact conformation, product is attractive in appearance, firmly degree is high.
In above-mentioned elastic hinge for eyeglasses, described single tooth has fillet away from an end of slingshot shell.
One end and the slingshot shell of single tooth are connected, and the other end has fillet, and elastic hinge can not collide between single tooth and the hinge head when rotating, and the length of this kind structure energy proper extension list tooth increases the contact area of single tooth and pin-joint piece, and antihunting is effective.
In above-mentioned elastic hinge for eyeglasses, the end that described slingshot shell has mounting hole one end radially has along spring core runs through slingshot shell groove up and down.
After in spring core is installed to slingshot shell, can be inserted in the groove by an inserted sheet, make spring core protruding, make things convenient for spring core and hinge head to be hinged.
In above-mentioned elastic hinge for eyeglasses, described through hole is elongated, and described breach is elongated.
Strip has enlarged the lateral length of through hole, makes things convenient for the installation of bearing pin.
In above-mentioned elastic hinge for eyeglasses, described bearing pin is screw.
Compared with prior art, elastic hinge for eyeglasses provided by the invention has the following advantages:
1, the lateral surface of the pin-joint piece of this elastic hinge for eyeglasses fits on the medial surface of single tooth, even earpiece is pulled about by external force, earpiece can not swing yet, and the firm degree of earpiece is high, good stability.
2, have the gap between the pin-joint piece of the hinged end of the elasticity fuse of this elastic hinge for eyeglasses and hinge head, when elastic hinge rotated, there was not friction in this place, and earpiece rotates smooth and easy, good springiness.
