[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] Please refer to the following: Figure 1 and Figure 3 This application provides a screwless eyeglass frame, including: two posts, two pivots, two temples, and temples.

[0021] Two posts 2 are symmetrically installed on both sides of the lens frame 1. Two parallel through slots 21 are formed at the end of each post 2 furthest from the lens frame 1. Two rotating shafts 22 are respectively installed within the two through slots 21, with their axes aligned vertically. Two temples 3 are symmetrically positioned outside the two posts 2, with the temples 3 partially flush against the outer side of the posts 2. At the end of each temple 3 near the posts 2, a first spring piece 31 and a second spring piece 32 extend into the two through slots 21. The ends of the first spring piece 31 and the second spring piece 32 are equipped with barbs 33, which are movably engaged from the inside of the posts 2 and elastically pressed against the rotating shafts 22. A temple 4 is movably fitted onto the end of the temple furthest from the posts 3.

[0022] It can be understood that the head 2 is a component connecting the frame and the temple 3. The through groove 21 is a channel that passes horizontally through the head 2. The first spring piece 31 and the second spring piece 32 are components with permanent elastic deformation capability, such as alloys, elastic plastics, etc., but not limited to these. Of course, the first spring piece 31 and the second spring piece 32 can be fixed to the temple 3 by welding, bonding, or other integrated methods.

[0023] As can be seen from the above, since the temple 3 is tightly attached to the outside of the post head 2, the barbs on the first spring 31 and the second spring 32 are elastically engaged from the inside of the post head 2 and elastically pressed against the pivot 22, thus forming a clamping effect on both the inside and outside of the post body. Furthermore, the movable engagement of the barbs with the pivot 22 ensures that the angle between the temple 3 and the post head 2 can be adjusted without affecting the folding of the temple 3. Even after the temple 3 is folded, the barbs on the first spring 31 and the second spring 32 elastically press against the pivot 22, and the temple 3 rests against the end of the post head 2, still forming a clamping effect, ensuring a stable connection between the temple 3 and the post head 2. The entire structure requires no hinges or screws, making it more ingenious and simple.

[0024] In some embodiments, the first spring 31 and the second spring 32 are integrally formed on the temple 33. This integral forming can be achieved by stamping or laser cutting, but is not limited to these methods. Through integral forming, the connection between the first spring 31 and the second spring 32 and the temple 3 is more secure and stable.

[0025] In some embodiments, the side of the post 2 near the temple 3 is provided with a rounded chamfer. Here, during the bending process of the temple 3, the post 2 and the inside of the temple 3 will have a fulcrum contact. The rounded chamfer can make the temple 3 fold more smoothly and can also reduce damage to the temple 3.

[0026] In some embodiments, the temple 4 is provided with a slot into which the temple 3 is inserted. In this way, the temple 4 can be movably fitted onto the temple 3.

[0027] In some embodiments, reference Figure 1 and Figures 4-5 The temple 3, at the end away from the head 2, has several positioning grooves 35 spaced apart on its outer wall. The temple 4 includes a cavity 41, a prying member 42, a pressing member 43, and a positioning block 44. The cavity 41 is located inside the temple 4, and the outer and inner walls of the temple 3 are respectively provided with a first through hole 47 and a second through hole 48 communicating with the cavity 41. The prying member 42 is located inside the cavity 41, with one end being a pressing end and the other end being a prying end, and the prying end passing through the second through hole 48 and pointing towards the positioning groove 35. The pressing member 43 is located at the pressing end of the prying member 42 and extends outward through the first through hole 47. The positioning block 44 is located at the prying end of the prying member 42 and is fitted into the positioning groove 35. The diameter of the second through hole 48 is larger than the diameter of the positioning block 44.

[0028] Understandably, the cavity 41 can be formed between the inner and outer double tubes of the temple 4; alternatively, it could be a small portion of the inner hollow structure of the temple 4. The pressing member 43 is a protruding component for pressing, such as a button-like structure, a rod-like structure, etc., but not limited to these. The fit between the positioning block 44 and the positioning groove 35 can be a round block with a round hole, a square block with a square hole, etc., but not limited to these. The diameter of the second through hole 48 is larger than the diameter of the positioning hole, allowing part of the positioning block 44 to be located within the second through hole 48 when the positioning block 44 is tilted up.

[0029] With this configuration, by pressing down on the pressing member 43, the positioning block 44 can be moved out of the positioning groove 35, and the temple 4 can slide on the temple 3. When the positioning block 44 is in the positioning groove 35, the position of the temple 4 on the temple 3 is fixed, realizing the length adjustment of the temple 4 and the temple 3, which is convenient for different users to meet the length requirements of wearing glasses.

[0030] In some embodiments, a housing 45 is provided on the outer wall of the temple 4 to enclose the pressing member 43. Here, the housing 45 can be made of materials such as rubber or silicone. The housing 45 can also seal the first through hole 47, which can both protect the pressing member 43 and prevent impurities from entering the cavity 41 through the first through hole 47.

[0031] In some embodiments, the prying member 42 includes an arc-shaped lever 421, a support rod 422, and a spring 423. The support rod 422 is disposed on the inner wall of the cavity 41 and is movably connected to the middle of the arc-shaped lever 421 to serve as a fulcrum. One end of the spring 423 is disposed on the inner wall of the cavity 41, and the other end elastically abuts against the end of the arc-shaped lever 421 near the pressing member 43.

[0032] Understandably, the support rod 422, acting as a fulcrum, can be connected to the arc-shaped lever 421 via hinges, ball joints, or other means. The spring 423 can be connected to the end of the arc-shaped lever 421 or directly rest against the bottom of the arc-shaped lever 421.

[0033] With this configuration, the spring 423 is in the upward position, and the positioning block 44 can be stably positioned in the positioning groove 35. Pressing the pressing member 43 causes the arc-shaped lever 421 to lift the positioning block 44, disengaging it from the positioning groove 35. When the pressing member 43 is stopped, due to the action of the spring 423, the positioning block 44 continues to elastically press down on the temple 3 until it slides into the positioning groove 35.

[0034] In some embodiments, the inner side of the outer wall of the temple is provided with anti-slip texture 46, which can increase the friction of the temple 4, making the user more stable when wearing glasses and less likely to slip off.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
