Description

Technical Field

[0001] The utility model relates to the field of glasses manufacturing, in particular to a screwless hinge structure. Background Art

[0002] Glasses are a very practical tool, widely used in vision correction, eye protection, decoration and special purposes. Glasses are a very practical tool, widely used in vision correction, eye protection, decoration and special purposes. With the continuous advancement of technology, the design of glasses is also constantly improving.

[0003] The Chinese utility model patent with publication number "CN220795603U" discloses a screwless elastic glasses hinge structure, including a pile head and a glasses leg. The pile head and the glasses leg are hinged to each other, one end of the pile head is a U-shaped structural spring piece, and the front end of the spring piece is provided with an open front connecting end, and the front connecting end has a certain elasticity under the action of external force, and two or more limit card points are provided inside the front connecting end. A groove body is provided in the middle of the front connecting end of the pile head to divide the front connecting end of the pile head into two parts, upper and lower parts, a flat rear connecting end is provided at the front end of the glasses leg, and two openings are provided on the rear connecting end of the glasses leg, and a first positioning shaft and a second positioning shaft are installed in the openings. The rear connecting end of the glasses leg is installed in the groove body of the front connecting end of the pile head, and the front connecting end and the rear connecting end have the same structure. The rear pile head connecting end of the glasses leg can rotate in the groove body. The number and position of the glasses leg positioning shaft and the pile head limit card points serve to control the opening angle of the glasses leg and fix them to each other with the pile head.

[0004] However, the screwless elastic hinge structure's stop points somewhat restrict the maximum angle the temples can open and close. When the temples are fully opened and squeezed by external forces, they are more susceptible to breakage due to their limited range of motion. This situation not only inconveniences users but also poses a potential safety hazard. Furthermore, traditional eyewear designs are often too monotonous, lacking innovation and interest. Therefore, eyewear design needs to keep pace with the times and incorporate more creative elements to meet consumers' pursuit of fun and personalization.

[0005] To sum up, in order to enhance user experience, ensure product durability and safety, and meet the market demand for innovation and personalization, it is particularly necessary to improve the existing screwless elastic eyeglass hinge structure. Utility Model Content

[0006] The purpose of this utility model is to provide a screwless hinge structure to solve the above problems existing in the prior art.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a screw-free hinged structure, including a post and a temple, a front connecting end is provided at one end of the post, and a rear connecting end is provided at the end of the temple close to the post, the front connecting end is provided with an integrally formed limiting through-hole, and the rear connecting end is provided with a plurality of positioning bolts, and the temple and the post are hinged through the interference between the positioning bolts and the limiting through-holes, and the position of the positioning bolts and the post of the temple serves to control the opening angle of the temple.

[0008] By adopting the above technical solution: the pile head is provided with an integrally formed limiting through-hole, and the positioning bolt contacts the inner edge of the limiting through-hole. Compared with the method of limiting the maximum opening and closing angle of the temple by the pile head limiting card point in the prior art, this application eliminates the need for the temple limiting mechanism, and at the same time realizes the large-angle opening and closing rotation of the temple relative to the pile head, which not only solves the problem of the temple breaking due to extrusion in the open state, but also maintains stability at any angle relative to the pile head, providing a larger adjustment space to adapt to the face shape and wearing habits of different users. In addition, users can easily install and remove the temples according to their needs, which not only improves the practicality of the glasses, but also increases their fun and personalized options.

[0009] The above-mentioned screwless hinged structure can be further configured as follows: the limiting through hole is a polygonal structure, the edge of the limiting through hole is provided with a certain curvature, the positioning bolt is a cylindrical structure, and the edge curvature of the limiting through hole cooperates with the outer curvature of the cylindrical structure of the positioning bolt to realize the connection and fixation of the rear connection end.

[0010] By adopting this technical solution, the carefully designed inner curvature of the limiting through-holes and the outer curvature of the cylindrical structure of the positioning shaft complement each other. This screwless hinged structure achieves a precise control of the temple opening and closing angles, which not only enhances the durability of the glasses but also optimizes the user's wearing experience. The defined opening and closing angles ensure that the temples fit the user's head tightly, providing a stable and comfortable wearing experience while reducing the risk of eye or facial injuries caused by accidental temple folding.

[0011] The above-mentioned screwless hinged structure can be further configured as follows: a groove is provided at the front connecting end, a slot is provided at the rear connecting end, the rear connecting end is in a U-shaped structure, the rear connecting end is placed in the groove by extruding the U-shaped structure and positioning bolts are provided at both ends of the U-shaped structure to achieve hinged connection with the pile head.

[0012] By adopting the above technical solution: the temple passes through the U-shaped structure of the rear connecting end, the U-shaped structure is extruded so that the width of the two end portions is consistent with the width of the limiting through hole, and positioning bolts are penetrated at the end to realize the clamping connection between the temple and the pile head. At the same time, the U-shaped structure of the rear connecting end can increase the strong stress.

[0013] The above-mentioned screwless hinged structure can be further configured as: the temples are divided into a first temple and a second temple, the width of the first temple is greater than the width of the second temple, and a resistance block is provided at one end of the first temple near the second temple, the width of the resistance block is greater than the width of the middle part of the first temple, and the second temple has a certain curvature biased towards the frame and can be adapted to a variety of glasses leg covers.

[0014] By adopting the aforementioned technical solution, the differentiated temple design—where the first temple is wider than the second—not only enhances support and stability near the temple tip, but also makes the overall structure more durable. The curved design of the second temple significantly improves fit, allowing a pair of glasses to be adapted to a variety of occasions and user needs by replacing different temple covers, thus enabling personalized customization. This design optimizes the user's wearing experience, making the glasses both comfortable and practical, providing a good fit and stable support for sports, work, and daily life.

[0015] The screwless hinged structure can be further configured as follows: an end of the pile head away from the limiting through hole is provided with an integrally formed first weight-reducing hole, and the first weight-reducing hole is in the shape of an elongated strip and passes through the pile head.

[0016] By adopting the above technical solution: by opening a first weight-reducing hole in the pile head, this screwless hinged structure design effectively reduces the weight of the glasses, which is crucial for improving wearer comfort, especially during prolonged wear. While reducing weight, this design also takes aesthetic factors into consideration, cleverly integrating the weight-reducing hole into the overall design of the glasses. This not only plays a functional role, but also adds a decorative effect and improves the appearance. This improvement makes the glasses more comfortable to wear while maintaining a stylish and beautiful appearance, meeting the user's dual needs for glasses that are both practical and fashionable.

[0017] The screwless hinge structure can be further configured as follows: a plurality of second weight-reducing holes are provided at one end of the first temple close to the stud, and the second weight-reducing holes are evenly distributed at intervals at the end of the first temple close to the U-shaped structure.

[0018] By adopting the above-mentioned technical solution: by creating multiple secondary weight-reducing holes at the end of the first temple near the base, this screwless hinged structure design has achieved significant improvements in wearing comfort. These evenly distributed weight-reducing holes effectively reduce the weight of the temples, making it easier to wear glasses for extended periods of time. At the same time, the even weight distribution helps maintain the balance of the glasses when worn, reducing pressure on the ears or side of the head, and improving overall comfort. This design also enhances the durability and stability of the temples, ensuring the reliability of the glasses in various usage conditions. Finally, the improved breathability and heat dissipation provide users with a more pleasant wearing environment, especially in warm or hot conditions. These comprehensive improvements provide users with a pair of glasses that are both practical and stylish, comfortable and durable.

DETAILED DESCRIPTION

[0031] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0032] like Figures 1 to 6 The screwless hinged structure shown includes a post and temples. A front connection end is provided at one end of the post, and a rear connection end is provided at the end of the temple near the post. The front connection end is provided with an integrally formed limiting through-hole, and the rear connection end is provided with a number of positioning bolts. The temple and the post are hinged by the positioning bolts and the limiting through-holes. The position of the positioning bolts and the post of the temple is used to control the opening angle of the temple. The positioning bolts and the inner periphery of the limiting through-holes interfere with each other, eliminating the need for a temple switch limiting mechanism, while achieving a 180° opening and closing rotation of the temple relative to the post. This not only avoids the problem of temple fracture caused by extrusion in the fully open state, but also maintains stability at any angle, providing greater adjustment space to accommodate different users' face shapes and wearing habits. In addition, users can easily install and remove temples according to their needs, which not only improves the practicality of the glasses, but also increases their fun and personalized options.

[0033] like Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 The illustrated retaining hole is a polygonal structure with a defined curvature along its edges. The positioning pin is a cylindrical structure, and the curvature of the retaining hole's edges aligns with the outer curvature of the cylindrical structure of the positioning pin to secure the rear connection. This coordination of the retaining hole's curvature with the outer curvature of the cylindrical structure of the positioning shaft allows for precise control of the temple's opening and closing angles, enhancing the durability of the glasses and optimizing the user's wearing experience. The defined opening and closing angles ensure a snug fit of the temples on the user's head, providing a stable and comfortable fit while reducing the risk of eye or facial injury from accidental temple folding.

[0034] like Figure 1 、 Figure 3The temples 3 shown are divided into a first temple 31 and a second temple 32. The width of the first temple 31 is greater than the width of the second temple 32. The first temple 31 is provided with a contact block 311 near one end 32 of the second temple. The second temple 32 has a certain curvature to adapt to a variety of temple sets 3. The differentiated design of the temples 3, that is, the width of the first temple 31 is greater than the second temple 32, not only enhances the support and stability near the base 2, but also makes the overall structure more durable. The curvature design of the second temple 32 significantly improves the adaptability, allowing a pair of glasses to adapt to various occasions and user needs by replacing different temple sets 3, thus realizing the possibility of personalized customization. This design optimizes the user's wearing experience, making the glasses both comfortable and practical, and providing good adaptability and stable support for sports, work, and daily life.

[0035] like Figure 2 、 Figures 4 to 10 The illustrated head 2 is provided with a first weight-reducing hole 24, which extends through the end of the head 2 near the frame 1. This effectively reduces the weight of the glasses, which is crucial for enhancing wearer comfort, especially during extended wear. While reducing weight, this design also takes aesthetics into account, cleverly integrating the weight-reducing hole into the overall design of the glasses. This not only serves a functional purpose but also adds a decorative effect and improves the appearance. This improvement makes the glasses more comfortable to wear while maintaining a stylish and aesthetically pleasing appearance, satisfying users' dual needs for practical and fashionable glasses.

[0036] like Figures 3 to 10 The first temple 31 shown has multiple second weight-reducing holes 37 at one end near the base 2. The second weight-reducing holes 37 are evenly spaced at intervals at the end of the first temple 31 near the U-shaped structure 34, making significant progress in improving wearing comfort. These evenly distributed weight-reducing holes effectively reduce the weight of the temple 3, making it easier to wear glasses for long periods of time. At the same time, the even weight distribution helps maintain the balance of the glasses when worn, reduces the pressure on the ears or one side of the head, and improves overall comfort. In addition, this design also enhances the durability and stability of the temple 3, ensuring the reliability of the glasses under various conditions of use. Finally, the improved air permeability and heat dissipation provide users with a more pleasant wearing environment, especially under warm or hot conditions. These comprehensive improvements provide users with a practical, stylish, comfortable and durable glasses option. Example 2

[0037] Figures 7 to 10The screwless hinged structure shown in the figure has a flat rear connecting end 33 and a slot 331. The rear connecting end 33 is a U-shaped structure 34. The temple 3 is compressed against each other by the U-shaped structure 34 and placed in the slot body 23. Positioning bolts 35 are respectively passed through the two ends of the U-shaped structure 34, so that the positioning bolts 35 are against the inner edge of the limiting through hole 22 to realize the hinged connection of the temple 3 and the pile head 2. The U-shaped structure 34 of the rear connecting end 33 can increase the strong stress. The positioning bolts 35 and the positioning bolts 36 are in conflict with the four sides of the limiting through hole 22 to fix the temple 3 and the pile head 2. The temple 3 can realize the movement of the positioning bolts 35 and the positioning bolts 36 along the four sides of the limiting through hole 22 through the stress of the U-shaped structure 34, thereby realizing the opening and closing of the temple 3 relative to the pile head 2.

[0038] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
