Description

Technical Field

[0001] The utility model relates to the technical field of glasses, and more particularly to a spring piece and a replaceable and multifunctional elastic hinge structure. Background Art

[0002] The wearing comfort and durability of glasses have always been the focus of attention. The connection between the frame and the temples of traditional glasses, namely the hinge structure, usually adopts a rigid design. After the temples of the glasses are opened, the angle between the temples and the frame is basically maintained in a vertical state, and the temples cannot continue to rotate outward relative to the frame; although the hinge of this structure is simple and direct, but because the temples cannot continue to rotate outward relative to the frame, when users with large head circumference wear glasses, the wearing comfort is reduced due to too tight clamping. If worn continuously, the two temples will be forced to expand outward. This unnatural expansion can easily cause damage to the temples and the hinges connected to the temples, affecting the service life of the glasses.

[0003] Therefore, how to provide an elastic hinge structure with a simple structure that can be worn by people with different head circumferences, while improving wearing comfort and durability, and can be applied to glasses of different types and materials, and can also provide versatility and diversified shaping conditions for eyeglass products, is a problem that technical personnel in this field urgently need to solve.
