Background

The glasses generally comprise a glasses frame and lenses, and the glasses frame is formed by connecting a glasses frame and glasses legs through hinges. The glasses hinge is used as a key movable part in the glasses, and the stability and the reliability of the glasses hinge directly influence the normal use of the glasses. The existing glasses hinges are mostly formed by adopting screw connection, the frequently movable glasses legs easily cause screws to loosen and fall off, the rotation tightness degree of the glasses hinges is usually determined by the screwing degree of the screws, and the glasses legs can become loose after a plurality of glasses are used for a period of time, and the glasses legs cannot be stably packed up when not used.

In view of the above problems of the conventional eyeglass hinge, some screw-free elastic eyeglass hinge structures have been proposed, such as an "eyeglass frame" disclosed in chinese patent No. ZL201120419289.2, which includes an eyeglass frame and earpieces, wherein two sides of the eyeglass frame respectively extend out of an extension portion that is matched with the earpieces, one end of the earpieces that is matched with the extension portion is provided with two elastic legs and a hinge leg, the hinge leg is located between the two elastic legs, a clamping structure is formed between the elastic legs and the hinge leg and clamped on the extension portion, the elastic legs are located outside the extension portion, the hinge legs are located inside the extension portion, and the hinge legs are hinged to the extension portion. The patent application utilizes the clamping structure formed between the elastic foot and the hinge foot to clamp the extending part, so that the combination of the glasses foot and the glasses frame is not easy to be separated; in addition, the elastic foot elastically deforms in the rotating process, so that the elastic foot always exerts pressure on the extending part and keeps the clamping state of the spectacle leg on the spectacle frame; the hinge foot is hinged with the extending part, so that the spectacle foot and the spectacle frame realize the hinging function, and finally, the elastic hinging structure of the spectacle foot and the spectacle frame without screw matching is realized.

Also, as disclosed in chinese patent No. zl201922097400.x, "an elastic hinge structure of glasses and glasses including the same" includes a first hinge member and a second hinge member, a hinge joint is formed at one end of the first hinge member, an elastic hinge structure is provided at one end of the second hinge member, the elastic hinge structure includes a hinge part and a limiting part which are arranged at left and right intervals, rear ends of the hinge part and the limiting part are connected together through two elastic connecting arms, so that an interval between the hinge part and the limiting part can be elastically expanded and enlarged, the hinge joint of the first hinge member can be inserted between the hinge part and the limiting part and rotatably connected to the hinge part from the middle of the two elastic connecting arms, and the first hinge member can be rotated to an open state parallel to each other or a closed state bent inward with respect to the second hinge member by a limiting effect of the limiting part. The first hinge part and the second hinge part of the application are in running fit without screws or rotating shafts, and are convenient and quick to assemble through the hinged fit of the hinge head and the elastic hinge structure, and the assembling efficiency can be improved.

However, the hinge structure of the existing screw-free elastic glasses adopts an integrally formed elastic piece structure design, the processing technology is complex, and the dimensional precision is not easy to guarantee. In addition, the integrally processed structure also limits the style of the glasses hinge, so that the shape and the style of the glasses hinge part are difficult to further expand, and the product style of the glasses is not beneficial to being enriched. In addition, the integrally formed spring structure needs to use more metal spring materials, which is not beneficial to enriching the application of the glasses materials.
