Description

Technical Field

[0001] The utility model belongs to the technical field of glasses manufacturing, and particularly relates to a spring hinge mechanism for glasses legs. Background Art

[0002] The hinge structure between the temples and the frames of existing glasses is mostly connected by screws to achieve the folding of the temples. In order to achieve a more comfortable wearing effect, the material of the temples is selected to be a thin steel sheet that can undergo elastic deformation, so that the temples can be bent outwards, making them more comfortable to wear. However, this type of temple has special requirements on the material and cannot meet the personalized needs of users. Announcement No. CN221507276 U discloses an invisible elastic glasses hinge, which includes: a glasses pile head, a single-hinge long axis, a decorative cover, a single-hinge long axis, and glasses legs; the glasses pile head and one end of the single-hinge long axis are fixedly connected to each other by a hinge screw structure; a spring is inserted into the rear part of the single-hinge long axis and is fixedly connected to the metal axis bud hole set in the front end of the fixed block through the long axis thread bud at the rear part of the single-hinge long axis; a fixing block screw hole is set on the tail of the fixing block, and the fixing block is inserted into the metal axis hole position of the temple set inside the glasses leg, and then a screw is passed through the glasses leg screw hole that is connected with the metal axis hole position of the temple and is screwed and fixed to the metal axis screw hole set at the tail of the fixing block; the combined structure of the single-hinge long axis, spring, and fixed block is wrapped with a decorative cover on the outside. It increases the opening and closing angle of the glasses and reduces the pressure of the glasses legs on the user by installing an elastic device in the hinge. However, it has many parts and complex connection relationships, resulting in high processing costs and inconvenient subsequent repair and maintenance. In addition, when the legs of traditional glasses are closed, the ends of the legs will contact the frame, thereby accelerating the wear of the legs and shortening the service life of the glasses.

[0003] Therefore, the above problems should be considered and solved in the process of designing and producing the temples of glasses. Utility Model Content

[0020] The following will describe the implementation of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] As shown in the figure, the present invention provides a spring hinge mechanism for the temple of glasses, comprising a temple 1 and a stud 2, wherein the temple 1 and the stud 2 are connected via a hinge assembly, wherein the hinge assembly comprises a connecting seat 3 welded to one end of the temple 1, a connecting sleeve 4 welded to one end of the stud 2, a torsion spring 5, a fixing pin 6, and a fixing seat 7. The connecting sleeve 4 is provided with an arc-shaped notch 8 on the side connected to the connecting seat 2, so that the connecting seat 2 is embedded in the side end of the connecting sleeve 4. The outer wall of the connecting seat 3 is provided with a first limiting groove 9, and the side wall of the connecting sleeve 4 is provided with a second limiting groove 10. The torsion spring 5 is disposed in the connecting sleeve 4, and the two ends of the torsion spring 5 are respectively fixed in the first limiting groove 9 and the second limiting groove 10. The fixing pin 6 has a T-shaped cross-section and includes a pressing surface 11 and a positioning shaft 12. The positioning shaft 12 is inserted into the torsion spring 5. The pressing surface 11 is placed on one end face of the connecting sleeve 4. A through hole is provided in the middle of the fixing seat 7 to match the positioning shaft 12. The fixing seat 7 and the positioning shaft 12 are fixed to the other end face of the connecting sleeve by an interference fit. The hinge mechanism of this embodiment fixes the two ends of the torsion spring 5 in the first limiting groove 9 and the second limiting groove 10, respectively. By providing the torsion spring 5, the temples can have a certain elastic force, so that they can be expanded to a suitable width according to each person's face shape, so that the temples can automatically tighten and fit the face, thereby improving the customer applicability of the frame. The pile head 2 is provided with a bending portion 13 with a bending angle of 110°. The other end of the bending portion 13 is fixed to the frame, and the pile head is bent to 110°. The setting of this angle allows the temples to automatically fold inward when the glasses are stored during actual use. When folding inward, the temples are elastically positioned due to the limitation of the torsion spring 5, and the temples will not be completely closed to the lowest point, so that the tails of the temples will not touch the frame, avoiding contact between the temples and the frame, and not causing wear on the frame, thereby extending the service life of the frame.
