[0002] Eyeglasses can correct various vision problems, including myopia, hyperopia, astigmatism, presbyopia, strabismus, or amblyopia. Eyeglasses are composed of lenses and frames, and are used to improve vision, protect the eyes, or serve as decoration. With the rapid development of my country's economy, the eyeglasses industry has also developed vigorously. In addition to their initial use for vision correction, people also regard eyeglasses as a fashion accessory, and have increasingly higher requirements for the shape of the lenses and the style of the frames.
[0003] Most existing eyeglass frames use screws to fix the temples to the frame. During daily use, due to the frequent opening and closing of the temples, the small screws can easily loosen or even fall off, requiring regular tightening. If not maintained for a long time, screws can easily be lost, causing the temples to separate from the frame. Furthermore, after sweating during daily use, there are blind spots at the connection between the temples and the frame, making cleaning and maintenance difficult.
[0004] Therefore, a screwless eyeglass frame is proposed to solve the above problems. Utility Model Content

[0034] Reference Figures 1 to 6 The present invention relates to a screwless eyeglass frame, comprising a frame connector 100 and a temple 200, wherein the temple 200 and the frame connector 100 are hinged together by a hinge 300.
[0035] The hinge 300 includes a pin 310 and a rotating shaft 320. The frame connector 100 and the temple 200 are both connected to the rotating shaft 320, and the pin 310 is inserted into the rotating shaft 320.
[0036] The rotating shaft 320 is provided with a mounting hole 400, and the pin 310 is inserted into the mounting hole 400;
[0037] The pin 310 is interference-fitted with the mounting hole 400;
[0038] The temple has a through hole on the side near the frame connector. When the temple is connected to the frame connector, the through hole is aligned with the mounting hole.
[0039] In this embodiment, the frame connector 100 and the rotating shaft 320 are integrated. The temple 200 has a through hole 210. When installing the temple 200 and the frame connector 100, after aligning the through hole 210 of the temple 200 with the mounting hole 400 on the rotating shaft 320, the pin 310 is inserted into the hole. In this embodiment, the diameter of the pin 310 is 1.25mm, and the diameter of the mounting hole 400 is 1.20mm. The pin 310 and the mounting hole 400 are interference-fitted to achieve a hinged connection between the temple 200 and the frame connector 100. This design eliminates the traditional screw structure and uses a pin 310 and a rotating shaft 320 to form a hinged connection. The hinge 300 design avoids the problem of loose or missing screws, fundamentally improving the reliability and durability of the eyeglass frame. In daily use, due to the frequent opening and closing of the temples 200, traditional screw connections often loosen or even fall off due to mechanical fatigue, causing the temples 200 to separate from the frame connector 100. However, the hinge structure using pins 310 and rotating shafts 320 can withstand frequent mechanical movements while maintaining a firm connection, significantly improving service life and stability. In addition, the hinge design in this embodiment reduces the possibility of dirt accumulating at the connection between the frame connector 100 and the temples 200, making cleaning and maintenance simpler and faster.
[0040] The rotating shaft 320 is provided with a groove 500, and the pin 310 is inserted into the rotating shaft 320. The pin 310 protrudes from the opening sidewall of the groove 500.
[0041] The groove 500 has an inwardly concave arc shape;
[0042] In this embodiment, a curved groove 500 is provided on one side of the rotating shaft 320. When the pin 310 is inserted into the mounting hole 400, the tail end of the pin 310 protrudes from the opening wall of the curved groove 500. The groove 500 is concave and curved. After the pin 310 is inserted into the mounting hole 400, its tail end will protrude from the opening side wall of the curved groove 500. The operator can flatten the protruding part of the pin 310 by tapping it, so that the pin 310 changes from the initial T-shaped structure to an I-shaped structure, thereby further fixing the pin 310 and making the connection between the pin 310 and the rotating shaft 320 more stable. The design of the curved groove 500 is precisely to accommodate this tapped pin end, ensuring that the pin 310 can be firmly fixed in the rotating shaft and will not loosen due to external force or frequent operation; at the same time, it prevents the tail end of the pin 310 from continuing to protrude, ensuring that the overall structure is flat, simplifying the assembly process and improving production efficiency.
[0043] The arc-shaped groove 500 not only provides space for the deformation of the pin 310, avoiding protrusions or depressions from affecting the overall appearance, but also prevents the protruding pin 310 from scratching or causing discomfort to the skin or fingers. Especially when adjusting glasses, the parts that the user touches are smoother, avoiding the risk of scratches; it also makes the frame structure look flatter and more beautiful.
[0044] The rotating shaft 320 includes a first limiting surface 330 and a second limiting surface 340, and the temple 200 rotates between the first limiting surface 330 and the second limiting surface 340.
[0045] Based on the above embodiments, the temple 200 is provided with a first abutment portion 220 and a second abutment portion 230 on the side near the frame connector 100. When the temple 200 is unfolded, the first abutment portion 220 cooperates with the first limiting surface 330. This design ensures that the temple 200 can stop stably when unfolded to a preset angle. On the one hand, it enhances the stability of the temple 200 when unfolded, preventing loosening or angle deviation during use. On the other hand, it helps to provide users with the best wearing angle and comfort, ensuring that the temple 200 fits the face consistently and improving the overall wearing experience of the glasses. When the temple 200 is bent and stored, the second abutment portion 230 cooperates with the second limiting surface 340 to prevent the temple 200 from being damaged or deformed due to excessive bending. At the same time, it ensures that the glasses are compact in the stored state, making them easy to carry and store. That is, the cooperation of the first abutment portion 220 and the first limiting surface 330, as well as the second abutment portion 230 and the second limiting surface 340, limits the maximum rotation angle of the temple 200.
[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
