Description

Technical Field

[0001] This utility model relates to the field of eyeglasses, specifically to a hinge structure for eyeglass frames. Background Technology

[0002] Eyeglasses, as a common vision correction and protection product, typically consist of lenses, frames, temples, and a hinge structure connecting the frames and temples. The hinge structure is a key component of eyeglasses, and its performance directly affects the smoothness of opening and closing, wearing comfort, and overall lifespan. Most existing eyeglasses use a screw-fastening connection method for their hinge structures. This involves mounting holes at the end of the frame, where screws engage with hinge plates at the temple ends, allowing the temples to open, close, and rotate relative to the frame. This traditional structure has some shortcomings in practical use.

[0003] First, the screw fastening method is highly dependent on the assembly process. During production and maintenance, screws are prone to stripping, loosening, or even falling off, causing the connection between the temple and the frame to become loose or completely separate, thus affecting the normal use of the glasses. To prevent screws from loosening, it is often necessary to use glue to fix them or to repeatedly tighten them to maintain the reliability of the connection, but this increases production costs and the complexity of later maintenance to some extent.

[0004] Secondly, some hinge structures use welding to connect the temples to the frame. While welding improves stability, it involves complex assembly processes, requires additional welding equipment and process control, and the welds may break due to stress concentration during long-term use. Furthermore, the welded connections are not detachable, hindering maintenance and replacement, thus limiting the overall lifespan of the glasses.

[0005] Secondly, traditional screw or welded hinge structures make it difficult to achieve a fixed-point stopping function for the temples during use. When wearing the glasses, the temples can only be fully open or closed, and cannot stay at a fixed angle according to wearing needs, resulting in insufficient wearing comfort, especially in scenarios requiring specific angle adjustments.

[0006] In addition, the existing hinge structure has a relatively complex size design and requires high processing precision. Some products have a large structural volume, which increases the weight of the glasses and can easily cause users to feel pressure or discomfort when wearing them for a long time. This does not conform to the development trend of lightweight and comfortable products. Summary of the Invention

[0007] To address the aforementioned problems, this utility model provides a hinged structure for eyeglass frames, which is easy to assemble, requires no screws or welding, and enables the temples to remain stationary at a fixed point, effectively overcoming the shortcomings of the prior art.

[0008] This utility model is achieved through the following technical solution: a hinged structure for eyeglass frames, comprising:

[0009] The frame connector is used to connect the eyeglass frame and the hinge structure in assembly.

[0010] A hinge structure is used to connect the temples of eyeglasses. The temples are rotatably mounted in the frame via the hinge structure, and the hinge structure enables the temples to stay at a fixed point.

[0011] As a preferred technical solution, the hinge structure includes: a hinge clip and a hinge pivot. A pivot mounting hole is provided on the temple of the eyeglasses. The hinge pivot is disposed in the pivot mounting hole. The hinge clip is disposed at the upper and lower ends of the hinge pivot and is installed together into the headpiece.

[0012] As a preferred technical solution, the head has a U-shaped locking groove, and the hinge structure is locked in the U-shaped locking groove.

[0013] As a preferred technical solution, the hinge core includes a main body and a connecting shaft. The connecting shaft is disposed at the upper and lower ends of the main body. The hinge clip includes an upper hinge clip and a lower hinge clip. The upper hinge clip and the lower hinge clip are provided with connecting holes corresponding to the positions of the connecting shaft. The connecting holes and the connecting shaft are both polygonal in shape. The upper hinge clip and the lower hinge clip are assembled with the connecting shaft on the hinge core through the connecting holes.

[0014] As a preferred technical solution, the rotating core mounting hole is polygonal in shape and has multiple positioning edges, and the main body is a polygonal main body with the same shape as the inner wall of the rotating core mounting hole.

[0015] As a preferred technical solution, the inner wall of the rotating core mounting hole is provided with an open relief groove.

[0016] As a preferred technical solution, the hinge head is made of metal, which elastically presses the hinge structure into place after the hinge structure is installed.

[0017] The beneficial effects of this utility model are: by setting a U-shaped mounting groove inside the frame and using a polygonal mating structure of hinge clip and hinge pivot, this utility model achieves a stable assembly between the temple and the frame. This not only avoids the problem of loosening and falling off of traditional screw connections, but also eliminates the complex procedures required for welding. The overall assembly process is simple and quick, and the structure can be fixed in a short time.

[0018] Meanwhile, the main body of the hinge rotating core cooperates with the polygonal rotating core mounting holes on the temple. With the help of the meshing relationship of the polygonal positioning edges, the temple can achieve a fixed-point stopping function at multiple angles during the opening process, thereby improving the wearer's comfort and convenience in different scenarios.

[0019] In addition, the hinge clips cooperate with the connecting shaft through polygonal connecting holes, ensuring the stability and reliability of the temple rotation and reducing wobbling and offset; the relief groove provides good guidance during the installation of the rotating core, improving the smoothness of assembly; furthermore, the hinge head uses metal parts and utilizes its elastic clamping effect to effectively clamp and fix the overall hinge structure, improving durability and service life.

[0027] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0028] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0029] like Figures 1-4 As shown, this utility model provides a hinged structure for eyeglass frames. Its overall structure is reasonably designed, which can realize a reliable connection between the temples 2 of the eyeglasses and the frame. It can also provide a fixed-point stopping function during use, thereby improving the comfort of wearing and the stability of use.

[0030] In this specific embodiment, the eyeglass frame hinge structure includes a head 7 and a hinge structure installed in the head 7. The head 7 serves as a mounting component at the end of the eyeglass frame, and its main function is to provide a fixed position for the assembly of the hinge structure and to achieve an overall connection with the eyeglass frame.

[0031] Zhuangtou 7 is made of metal parts, which can meet the requirements of long-term use in terms of strength and rigidity. At the same time, the metal material has a certain degree of elasticity. After the hinge structure is installed, Zhuangtou 7 can elastically compress the hinge structure, thereby further improving the stability of the assembly and preventing the structure from loosening.

[0032] In the specific structural design, the interior of the hinge 7 features a U-shaped mounting slot 8. This slot serves as the mounting cavity for the hinge structure, and its shape is adapted to the outline of the hinge structure. It allows the hinge clip and hinge pivot 12 to be fitted together and secured after assembly to maintain structural stability. The U-shaped structure of this mounting slot not only facilitates the assembly of the hinge structure but also provides lateral support for the hinge when subjected to external forces, preventing the rotating parts from shifting.

[0033] The hinge structure mainly consists of hinge clips and hinge pivot 12. The hinge pivot 12 is the core rotating component between the temple and the head 7, which enables the temple to rotate and open.

[0034] To ensure reliable assembly and smooth rotation, the temple is equipped with a pivot mounting hole 9. This mounting hole is polygonal in shape, with multiple positioning edges inside, which can engage with the main body 5 of the hinge pivot 12. The main body 5 of the hinge pivot 12 is also machined into a polygonal structure that matches the pivot mounting hole 9. When the main body 5 is inserted into the pivot mounting hole 9, the engagement of the polygonal positioning edges effectively prevents the pivot from rotating or slipping within the mounting hole, thereby ensuring the stability of the temple at the opening angle.

[0035] In the specific structure of the hinge core 12, it includes a main body 5 and a connecting shaft 6 provided at the upper and lower ends. The connecting shaft 6 serves as a positioning end during rotation and can cooperate with the hinge clip.

[0036] The hinge clip consists of an upper hinge clip 3 and a lower hinge clip 4. A connecting hole 11 is provided at the position corresponding to the connecting shaft 6. Both the connecting hole 11 and the connecting shaft 6 adopt a polygonal design. When the connecting shaft 6 is inserted into the connecting hole 11, it can form a surface-to-surface fit, thereby enhancing the anti-torsion ability and preventing the connection from loosening due to long-term rotation.

[0037] With this structural design, the hinge clip and the hinge pivot 12 can be reliably assembled into one piece and snapped into the U-shaped mounting groove 8 of the hinge head 7 to form a stable rotational hinge relationship.

[0038] To further improve assembly smoothness and adaptability, an open recessed groove 10 is provided on the inner wall of the pivot mounting hole 9. This groove provides space compensation for local positions during the insertion of the hinge pivot 12, making the assembly process smoother and preventing jamming or assembly difficulties due to excessive interference from polygonal corners. Simultaneously, this groove continues to act as a buffer and guide after the structure is assembled, ensuring smoother rotation of the temple.

[0039] In this specific embodiment, the hinge head 7, as a metal component, maintains good elasticity during processing. When the entire hinge structure is inserted into the U-shaped mounting slot 8, the hinge head 7 exerts a continuous elastic clamping force on the hinge clip and hinge pivot 12. This clamping force not only ensures the stability of the hinge structure during use but also creates a certain frictional positioning effect when the temple rotates to the open position, thus allowing the temple to remain stationary at a specific angle. This design allows users to position the temple at a suitable angle according to their needs when wearing glasses, avoiding the single state of the temple being only fully open or closed in traditional structures, thus improving the wearing experience.

[0040] The eyeglass frame hinge structure of this utility model, through the metal clamping of the head 7, the stable installation of the U-shaped mounting groove 8, the positioning and matching of the polygonal rotating core and the mounting hole, and the smooth assembly design of the relief groove 10, not only achieves the advantages of quick assembly and no need for screws and welding, but also ensures the stability and reliability of the opening and closing of the temples, and can achieve the function of stopping at a fixed point during use, ultimately achieving the effect of being lightweight, comfortable and safe to wear.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
