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 earpiece from swinging.
Background technology
The glasses in the past market sold, spectacle frame and earpiece mostly adopt the connected mode of hinge screws, and this hinged glasses clamping force is more weak, and earpiece is opened afterwards and the position of spectacle frame is fixing, earpiece can not be too much rotation, otherwise easily to damage.
For Problems existing, people have made improvement, and in existing glasses, earpiece and spectacle frame adopt elastic hinge to be connected mostly, and such as Chinese patent literature data discloses the eyeglasses frame elastic hinge [patent No.: 200820095445.2; Authorization Notice No.: 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, after spring is positioned at keeper, the inner of monodentate handle is provided with a flat position preventing spring from coming off; The outer end of monodentate core body is flexibly connected with hinge bidentate, and the keeper of slingshot core and spring are arranged in catapult box body, and slingshot core is removable connection by its keeper with catapult box body.
But the outer end of the monodentate core body of this kind of eyeglasses frame elastic hinge is exposed at outside catapult box body, the part be connected with pin thread position is only had to be positioned at the groove of catapult box body, after installation, the outer end of monodentate core body is positioned between the bidentate of hinge bidentate, if the gap that hinge bidentate coordinates with monodentate core body is little, the friction force between hinge bidentate and monodentate core body will be increased, earpiece will follow the string in moving process or elasticity very weak; If increase the gap that hinge bidentate coordinates with monodentate core body, earpiece after assembling can swing, poor stability, so in process, the tolerance of the diameter in the spacing between hinge bidentate bidentate and the radially direction of monodentate core body is very high, be difficult to control in reality batch production, and processing cost is high.
Summary of the invention
The object of the invention is for the above-mentioned problems in the prior art, provide one and can prevent earpiece from swinging, firmness is high, the elastic hinge for eyeglasses of good stability.
