Description
Technical Field
The utility model belongs to the technical field of the glasses structure, concretely relates to amorphous metal elasticity hinge structure and glasses for glasses.
Background
The glasses hinge is used for connecting the glasses legs and the glasses ring. When the glasses are used, the glasses legs are completely opened, are put on the ears and are clamped on the two sides of the face to play a role in fixing the glasses ring. At present, the materials of the spectacle frame are generally cupronickel, stainless steel and titanium alloy; the adopted processing technique mainly comprises machining, and in addition, the techniques of MIM (metal powder injection molding), lost wax mold casting and the like are also adopted.
The glasses hinge structure is easy to wear when being in a rotating opening and closing state for a long time, and the elasticity and the stability of the glasses hinge structure are reduced due to the wear condition; typically, the temples are connected to the frame by a hinge structure, which is typically the same as the frame material of the existing eyeglasses.
The cupronickel is the most commonly used spectacle hinge structural material in the current market because of convenient processing and low cost, but the material has no elasticity, and the clamping degree of spectacle legs is adjusted only by the tightness of hinge screws, so the wearing comfort is poor; after long-term use, the hinge is worn and deformed, which causes the imbalance of the glasses ring and influences the eyesight of the user.
Stainless steel hinges are also used in a wider range because they are stronger than cupronickel and slightly more flexible. Because the processing difficulty of stainless steel is higher, the cost is higher. Meanwhile, because the strength of the material is not high, the hinge can generate plastic deformation in the long-term use process, the glasses legs lose elasticity, and the wearing comfort is reduced. And because of the deformation, the left and right heights of the glasses ring are not balanced, and the vision of a user is influenced.
The titanium alloy hinge is generally used for high-end spectacle frames because the titanium material is not easy to process and the production cost is high. Due to single independent processing, the size of the hinge is unstable, the consistency is poor, and the quality stability of the finished glasses is poor. And more complicated elastic structures cannot be produced, and the elastic structures are limited.
