Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to a track-type bayonet screwless elastic eyeglass hinge structure. Background Technology

[0002] The track-mounted, screwless, flexible eyeglass hinge structure is a new type of connection structure used to connect eyeglass frames and temples. Its core is to achieve screwless assembly of the temples and temples through a track-mounted design, and to give the temples flexible opening and closing function by means of material properties and structural design. In the use of eyeglasses, the hinge needs to take into account the flexibility of temple opening and closing, the stability when wearing, and the compatibility with different head shapes. This structure was developed to meet users' needs for eyeglass wearing comfort, durability and convenience, and aims to solve many limitations of traditional hinges in practical applications through innovative design.

[0003] Traditional eyeglass hinges rely on screws to connect the temples to the frame. This structure has significant drawbacks: screws are prone to loosening or falling off due to frequent opening and closing, causing temples to wobble and jam, affecting the user experience and requiring frequent repairs. Furthermore, traditional hinges have limited elastic adjustment range, making it difficult to adapt to different head shapes. This can result in the glasses slipping due to being too tight or too loose. In addition, direct friction between metal parts accelerates wear and shortens the hinge's lifespan. Moreover, disassembly and assembly require tools, failing to meet users' personalized needs such as quick frame changes, thus limiting the usage scenarios and convenience of eyeglasses. Therefore, we have proposed a track-type, bayonet-style, screwless elastic eyeglass hinge structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a track-type bayonet screwless elastic eyeglass hinge structure, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a track-type bayonet-style screwless elastic eyeglass hinge structure, comprising:

[0006] The headpiece and temple are both made of titanium. The headpiece has an inner frame made of phosphor bronze. The headpiece and temple are connected without screws via a track structure.

[0007] Preferably, the bottom of the temple has a small notch, and the bottom of the inner frame of the temple has a small notch. The positions of the small notch at the bottom of the temple and the small notch at the bottom of the inner frame correspond, so that the temple neck on the side of the temple can be vertically inserted from the bottom to complete the connection.

[0008] Preferably, the top of the inner frame of the lens head is provided with a groove, which is a curved hidden track groove, and the front end of the temple is provided with a curved temple protrusion. The groove and the temple protrusion can be tightly fitted together, so that the temple opens and closes stably within the lens head.

[0009] Preferably, the temples can elastically expand outward by 12° when at 0°, improving wearing comfort and making the glasses fit the face better to prevent them from falling off.

[0010] Preferably, the top of the temple has a through-type fork, which enables the temple to have an elastic opening and closing function.

[0011] Preferably, a connecting block is fixedly connected to the side of the head, and a mirror frame is fixedly installed on the side of the connecting block.

[0012] Compared with the prior art, this utility model provides a track-type bayonet screwless elastic eyeglass hinge structure, which has the following characteristics:

[0013] Beneficial effects:

[0014] 1. This track-type, screwless, flexible eyeglass hinge structure utilizes a track-type, screwless connection. Through a small notch at the bottom of the hinge head and a vertical fit with the neck of the temple, combined with the curvature of the inner frame groove and the temple protrusion, a stable connection between the temple and the hinge head is achieved. The screwless design eliminates the risk of loose screws at the source. Furthermore, the titanium and phosphor bronze splicing structure reduces wear caused by direct metal-to-metal friction, significantly extending the hinge's lifespan and reducing maintenance frequency. This ensures smooth opening and closing even after long-term use. The forked temple design provides elasticity, allowing the temple to expand outwards by 12° from a 0° position, automatically adjusting the tightness according to different head shapes. When the temple reaches 45°... The forked sections fit together to form a small square. When tilted to 90°, the forks open and return to the large square track of the main frame, creating a 90° elastic effect. This multi-angle elastic adjustment allows the glasses to fit the face more closely, avoiding both the discomfort of being too tight and the slippage during wear, significantly improving the wearing experience. Through the vertical insertion structure of the corresponding notch at the bottom of the main frame and the neck of the temple, the connection and disassembly of the temple and main frame can be completed without auxiliary tools. This feature allows users to easily change different frames, such as using prescription frames indoors and quickly changing sunglasses lenses outdoors or while driving, meeting diverse eyewear needs. The convenient disassembly and assembly function greatly improves the flexibility of the glasses, expands the application scenarios, and better adapts to the user's personalized lifestyle.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model

[0021] Please refer to Figure 1-4 , the track-type bayonet screwless elastic spectacle hinge structure, comprising:

[0022] The hinge head 1 and the temple 6 are both made of titanium metal. The hinge head 1 is provided with an inner frame 2 of the hinge head, and the inner frame 2 of the hinge head is made of phosphor bronze metal. The hinge head 1 and the temple 6 are connected without screws through a track structure

[0023] Furthermore, a small notch 3 at the bottom of the hinge head 1 and a small notch 4 at the bottom of the inner frame 2 of the hinge head are provided. The positions of the small notch 3 at the bottom of the hinge head and the small notch 4 at the bottom of the inner frame of the hinge head correspond to each other, providing a vertical insertion from the bottom of the neck 7 on the side of the temple 6 to complete the connection. The small notch 3 at the bottom of the hinge head and the small notch 4 at the bottom of the inner frame of the hinge head are not only the positioning entrances during assembly, but their precise matching with the neck 7 of the temple can also form a lateral limit after assembly, preventing the temple 6 from shifting left and right during use. This double-notch corresponding design not only provides a clear path guidance for vertical insertion, but also enhances the overall firmness of the connection through the tight fit between the structures, ensuring that the temple 6 will not accidentally disengage from the hinge head 1 during frequent opening and closing, laying a foundation for the stable cooperation of the subsequent track structure

[0024] Furthermore, the top of the inner frame 2 of the headpiece has a groove 5, which is a curved hidden track groove. The front end of the temple 6 has a curved temple protrusion 8. The inner frame groove 5 and the temple protrusion 8 can fit together tightly, so that the temple 6 can open and close stably within the headpiece 1. The inner frame groove 5, as a curved hidden track groove, is designed to match the opening and closing angle of the temple 6. When the temple 6 rotates from 0° to 90°, the temple protrusion 8 slides along the curved trajectory of the inner frame groove 5. The curvature of the inner wall of the groove forms a continuous constraint on the protrusion. This constraint not only ensures the smoothness of the rotation process, but also avoids the problem of limited rotation angle caused by screw fixing in traditional hinges. At the same time, the hidden design makes the track structure not exposed, reducing the possibility of dust, sweat and other impurities entering, reducing the risk of poor opening and closing due to foreign objects, and maintaining a smooth feel during long-term use.

[0025] Furthermore, the temples 6 can elastically expand outward by 12° from the 0° position, improving wearing comfort and making the glasses fit the face better to prevent them from falling off. The 12° elastic expansion function of the temples 6 from the 0° position is not only due to the structural design of the temple bifurcation position 9, but also closely related to the excellent elastic properties of titanium itself. Titanium has high strength and toughness, and can quickly return to its original shape after being expanded under force. The synergistic effect of this material property and the bifurcation structure allows the temples 6 to provide sufficient clamping force to prevent slipping when fitting the head, without causing a feeling of pressure due to excessive rigidity. The 12° expansion range has been precisely calculated to cover the differences in head shape for most users. Whether the user has a wide or narrow head, they can get a close and comfortable wearing experience.

[0026] Furthermore, the top of the temple 6 has a through-type temple fork 9, which enables the temple 6 to have an elastic opening and closing function. The through-type design of the temple fork 9 makes the front end of the temple 6 form a structure similar to an "elastic clip". When the temple 6 is opened and closed under force, the two sides of the fork can produce symmetrical deformation, ensuring that the elastic force is evenly distributed. This symmetrical deformation characteristic avoids the temple 6 from tilting to one side during the opening and closing process, ensuring that the temple protrusion 8 and the inner frame groove 5 of the temple head always remain tightly fitted, and the track fit will not loosen due to uneven force. At the same time, the through depth of the fork is optimized, which can provide sufficient elastic deformation space without weakening the overall structural strength of the temple 6, thus taking into account both elastic function and structural durability.

[0027] Furthermore, the side of the frame 1 is fixedly connected to the connecting block 10, and the side of the connecting block 10 is fixedly installed with the frame 11. The fixed connection between the frame 1 and the frame 11 through the connecting block 10 makes the connecting block 10 the central hub for force transmission. When the temple 6 generates clamping force due to elastic expansion, the connecting block 10 can evenly distribute the force to the frame 11, avoiding excessive local force that could cause deformation of the frame 11. The material of the connecting block 10 is the same as that of the frame 1, both being titanium, ensuring the strength matching of the entire connection structure and preventing stress concentration due to material differences. In addition, the length and angle design of the connecting block 10 have been ergonomically optimized, making the connection position between the frame 11 and the temple 6 more in line with the facial contour, reducing indirect pressure on the bridge of the nose and ears when wearing glasses, and improving the overall balance of wearing glasses.

[0028] Structural Description:

[0029] Headpiece 1: Made of titanium metal, with an inner frame 2 inside and a small notch 3 at the bottom. It is connected to the temple 6 without screws via a track structure. The side is fixedly connected to the connecting block 10, which is the core component connecting the temple 6 and the frame 11.

[0030] The inner frame of the headpiece 2 is made of phosphor bronze metal. It has a small notch 4 at the bottom and an arc-shaped groove 5 at the top. It works with the headpiece 1 to achieve stable assembly and opening / closing of the temple 6.

[0031] Small notch 3 at the bottom of the headpiece: It is opened at the bottom of the headpiece 1, corresponding to the position of the small notch 4 at the bottom of the inner frame of the headpiece, so that the neck 7 of the temple 6 on the side of the temple 6 can be vertically inserted from the bottom, providing an entrance for connecting the temple 6.

[0032] Small notch 4 at the bottom of the inner frame of the headpiece: It is opened at the bottom of the inner frame of the headpiece 2, corresponding to the position of the small notch 3 at the bottom of the headpiece, and together they form an assembly channel for the neck of the temple 7, which helps to connect the temple 6 and the headpiece 1.

[0033] The inner frame groove 5 of the frame head is a hidden track groove with an arc at the top of the inner frame head 2, which can be tightly engaged with the temple protrusion 8 at the front end of the temple 6 to ensure that the temple 6 opens and closes stably within the frame head 1.

[0034] Temple 6: Made of titanium, with a temple groove 8 at the front end, a temple neck 7 on the side, and a temple fork position 9 at the top. It is connected to the head 1 via a track structure and has an elastic opening and closing function.

[0035] Neck of temple 7: Located on the side of temple 6, it can be vertically inserted through the small notch 3 at the bottom of the head and the small notch 4 at the bottom of the inner frame of the head to achieve connection and fixation between temple 6 and head 1;

[0036] Temple groove 8: This is a curved groove at the front end of the temple 6, which can fit tightly with the inner frame groove 5 of the temple, so that the temple 6 can maintain a stable fit during opening and closing.

[0037] Temple bifurcation position 9: It is located at the top of temple 6 and extends through it, so that temple 6 has an elastic opening and closing function. At 0°, it can elastically expand outward by 12°. At 45°, it closes tightly to form a small square. At 90°, it opens to match the large square track inside the temple head 1.

[0038] Connecting block 10: It is fixedly connected to the side of the head 1, and the mirror frame 11 is fixedly installed on the other side. It is used to transmit force and connect the head 1 and the mirror frame 11.

[0039] Frame 11: It is fixedly connected to the head 1 via the connecting block 10 and serves as the frame for mounting the lenses. It is affected by the linkage of the hinge structure to ensure the stability and comfort of wearing.

[0040] Working principle: When assembling the temple 6 with the headpiece 1, first clamp the front end of the temple 6, aligning its neck 7 with the corresponding small notch 3 at the bottom of the headpiece and the small notch 4 at the bottom of the inner frame of the headpiece. Insert it vertically upwards from the bottom until the front end of the temple 6 contacts the top of the opening of the headpiece 1, then release it. At this point, the curved groove 5 at the top of the inner frame 2 of the headpiece and the curved protrusion 8 at the front end of the temple 6 tightly engage, achieving a screwless connection through the track structure. This ensures that the temple 6 and the headpiece 1 are initially fixed. During daily use, the opening and closing of the temple 6 is guided by the curved track of the groove 5 in the inner frame of the headpiece and the protrusion 8. The tight engagement of the two allows the temple 6 to rotate stably within the headpiece 1, preventing wobbling or jamming. Simultaneously, the temple fork at the top of the temple 6... Position 9 plays a crucial role. When temple 6 is tilted to 45°, the forked position closes tightly to form a small square, enhancing structural stability. When tilted to 90°, the forked position quickly opens, returning to its matching state with the large square track inside the headband 1, creating a 90° elastic effect. This ensures smooth opening and closing and provides elastic cushioning. When temple 6 is in a 0° wearing position, the design of the forked position 9 allows it to elastically expand outward by 12°. This elastic adjustment automatically adapts to different head shapes, improving wearing comfort and making the glasses fit the face better to prevent them from falling off. In addition, the headband 1 and temple 6 are made of titanium, while the inner frame 2 of the headband is made of phosphor bronze. This splicing structure of different metals avoids the sticking sensation caused by direct friction between titanium metals, reducing... While ensuring smooth rotation despite wear, the hinge 1 is fixedly connected to the frame 11 via the connecting block 10, making the entire hinge structure the core hub connecting the frame 11 and the temple 6. The linkage of all components not only achieves the basic function of flexible opening and closing of the temple 6, but also eliminates the risk of loosening traditional screws through the screwless design. Elastic adjustment adapts to various head shapes, and the tight track ensures long-term stability. Ultimately, it achieves a comprehensive effect of requiring no frequent maintenance, providing comfortable and stable wear, and adapting to various usage scenarios. When it is necessary to disassemble the temple 6, simply clamp the front end of the temple 6 again, aligning the temple neck 7 with the small notch 3 at the bottom of the hinge and the small notch 4 at the bottom of the inner frame of the hinge, and remove it vertically downwards. The entire process is tool-free and convenient. In this linkage state... The curved fit between the inner frame groove 5 and the temple protrusion 8 ensures stable rotation of the temple 6, avoiding the wobbling caused by loosening of traditional screw connections. The elastic design of the temple fork 9 provides adaptability at different angles. The 12° elastic expansion at 0° meets the wearing needs of different head shapes, while the shape changes at 45° and 90° enhance the structural strength at specific angles and prevent excessive deformation. The titanium material of the lens 1 and temple 6, and the phosphor bronze material of the inner frame 2, utilize the properties of different metals to reduce friction and wear, extending service life. At the same time, the lightweight properties of titanium also improve the overall wearing comfort. The lens 1 is fixedly connected to the frame 11 through the connecting block 10, making the entire hinge structure the force-bearing hub of the glasses.The elasticity and stability of the temples 6 are transferred to the frame 11, ensuring that the glasses maintain overall stability and harmony during wear and use. This achieves an efficient, stable, and comfortable process from assembly to daily use and disassembly.
