[0002] The function of a hinge is to connect the temple to the frame, providing the opening and closing function of the temple and maintaining the stability of the entire frame. Currently in the eyewear industry, fixed hinge structures significantly limit the additional elastic adjustment of glasses. In response to this, some manufacturers have invented spring hinges. These spring hinges can automatically adjust the angle of the temple within a certain range to better accommodate people with different face shapes, but they still have limitations. The spring gradually relaxes with age, which not only affects the elastic force but also the angle of the temple, further affecting the wearing comfort and stability of the glasses. Furthermore, the complex structure of spring hinges increases the difficulty of production costs and technical risks.

[0003] Defects of the existing technology:

[0023] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, the utility model is a hinge for glasses, comprising a first connecting part 1 and a second connecting part 2, the first connecting part 1 comprising a threaded column 11 connected to the glasses frame 3 and a limiting column 12 arranged above the threaded column, the second connecting part 2 comprising two hinged parts 21 and a connecting member 22 connected to the glasses leg 4, the hinged part 21 comprising an annular part 211 connected to the middle of the connecting member and a movable arc-shaped part 212 connected to the outer side of the connecting member, a gap 213 is provided between the annular part 211 and the movable arc-shaped part 212, the outer side of the movable arc-shaped part 212 is in contact with the glasses leg 4, a pin shaft 5 is provided in the annular part 211, and the glasses leg 4 is installed in the groove 214 through the pin shaft 5, between the two hinged parts 21.

[0025] The utility model provides a hinge for glasses, which mainly includes a first connecting part 1 and a second connecting part 2. The first connecting part 1 includes a threaded column 11 and a limiting column 12. When installing, the threaded column 11 can be screwed into the glasses frame and fixed. The limiting column 12 is used to limit the installation position of the threaded column 11; the second connecting part 2 includes two hinged parts 21 and a connecting member 22. The connecting member 22 is connected to the top of the limiting column 12. The two hinged parts 21 are symmetrically arranged on both sides of the top of the connecting member 22, and a groove 214 for installing the legs of the glasses is provided in the middle thereof; the hinged part 21 includes an annular part 211 and a movable arc part 212. A gap 213 is provided between the annular part 211 and the movable arc part 212. When the legs of the glasses 4 need to move outward, the movable arc part 212 will move toward the annular part 211 to ensure that the distance between the legs of the glasses can be adjusted to adapt to people with different face shapes.

[0026] In a preferred embodiment, referring to Figure 1 and Figure 2The curvature of the movable arc part 212 of the hinge for glasses is greater than 1 / 2. The outer diameter of the limiting column 12 is greater than the outer diameter of the threaded column 11. The annular part 211 and the connecting part 22 are integrally formed, and the connecting part 22 is a bending structure. The first connecting part 1 and / or the second connecting part 2 is made of flexible material. By setting the curvature of the movable arc part 212 to be greater than 1 / 2, it is ensured that the outer side of the movable arc part 212 can contact the inner side of the glasses leg 4, thereby realizing the deformation of the movable arc part 212 and driving the glasses leg 4 to move outward; by setting the outer diameter of the limiting column 12 to be greater than the outer diameter of the threaded column 11, the stability of the hinge installation is ensured; by setting the first connecting part 1 and the second connecting part 2 as flexible parts, the glasses leg 4 can automatically adjust according to the wearer's face shape, thereby improving better comfort and adaptability, reducing wearing discomfort, and there is no need to consider the size of the wearer's face. The hinge can greatly improve the user experience.

[0027] The hinge for glasses of the present invention has the following features:

[0028] 1. The hinge is flexible and can automatically adjust the angle of the temple according to the wearer's face shape, so that the wearer can get a comfortable fit regardless of the size or shape of the face;

[0029] 2. Because the hinge can relieve the pressure caused by the fixed angle, the wearer will not feel uncomfortable when wearing glasses for a long time, especially avoiding pressure on the ears and nose bridge;

[0030] 3. The hinge structure is simpler and requires fewer parts, reducing production complexity and material costs;

[0031] 4. The hinge is more convenient during the manufacturing and installation process, reducing the need for complex tools and operations, which not only improves production efficiency but also reduces the difficulty and time cost of assembly in the factory;

[0032] 5. Due to the durability of the hinge, the service life of the glasses is extended, thereby reducing the waste generated by frequent replacement of glasses and being more environmentally friendly.

[0033] Compared to existing eyeglass hinges, this technology's greatest advantage lies in its automatic adaptability. Traditional hinges rely on fixed dimensions during wear, making it impossible to adjust the angle of the temples to suit different facial shapes. However, the elastic hinge structure of this invention automatically adjusts the temples to the wearer's face shape, providing a comfortable wearing experience regardless of facial size. This breakthrough eliminates the limitations of traditional eyeglasses in adapting to different face shapes and is the technology's greatest advantage.

[0034] The utility model also provides a pair of glasses, referring to Figure 1 、 Figure 3 and Figure 4The eyeglasses comprise a frame 3, temples 4, and lenses, and also include the aforementioned hinge for glasses. The hinge's first connecting portion 1 is connected to the frame 3, and its second connecting portion 2 is connected to the temples 4. The temples 4 can rotate vertically about the hinge, with a rotation angle of 0-30°. When a person with a small face wears the glasses, the temples 4 do not need to rotate, and their rotation angle is 0°. When a person with a large face wears the glasses, the temples 4 can rotate outward by 1-30°, with the rotation angle being determined by the face size. Furthermore, the rotation angle of the temples is associated with the size of the gap 213: a larger gap increases the rotation angle, and a smaller gap decreases the rotation angle.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
