[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] For reference as follows Figures 1-5 The present invention will be described as follows:

[0024] Example: A novel eyeglass frame structure, comprising a ring-shaped frame 1 (with lenses fixedly connected inside the eyeglass frame 1).

[0025] The frame 1 is provided with a disconnect groove 2 (the disconnect groove 2 is provided to facilitate the installation of the lens into the frame 1). The frame 1 on both sides of the disconnect groove 2 is provided with a fixing part 3, and also includes a fixing hole 31 that passes through the two fixing parts 3 (after the lens is installed, the frame 1 is fixedly connected at the disconnection point through the two fixing parts 3).

[0026] The annular frame 1 is used to fix the lens, and the opening groove 2 is designed to provide an opening for lens installation. The fixing parts 3 on both sides of the opening groove 2 are provided with fixing holes 31. After the lens is installed, the fixing connection at the opening of the frame 1 is achieved by connecting the connector through the fixing holes 31.

[0027] The frame 1 is provided with a hinge part 4, and the hinge part 4 is provided with a hinge hole 41. The hinge hole 41 provided by the hinge part 4 is used to establish a rotational connection with the temple of the glasses, so that the temple of the glasses can rotate around the hole to open and close.

[0028] The above describes the prior art; the following is the improved technical solution of this application:

[0029] Core improvement: The fixing hole 31 and the hinge hole 41 are set coaxially.

[0030] It also includes screws 5 that connect to the fixing hole 31 and the hinge hole 41. Screws 5 serve as pivots for the rotation of the temples. Screws 5 securely connect the two fixing parts 3.

[0031] The central axes of the two holes, fixing hole 31 and hinge hole 41, are on the same straight line. A screw 5 is introduced as a connector, passing through both fixing hole 31 and hinge hole 41. From a structural and functional perspective, screw 5 serves as a pivot for the rotation of the eyeglass temple, replacing the independent pivot in a traditional hinge structure; furthermore, the threaded connection of screw 5 secures the fixing parts 3 on both sides of the disconnected slot 2, achieving a fixed connection at the disconnection point of the frame 1.

[0032] During the assembly process, the lens is first inserted into the frame 1 through the disconnecting groove 2. Then, the fixing holes 31 of the fixing parts 3 on both sides are aligned with the hinge holes 41 of the hinge parts 4. Since the holes are coaxial, at this time, the screws 5 are simply passed through the hinge holes 41 and the fixing holes 31. By tightening the screws, both functions can be completed at the same time.

[0033] Advantages compared to existing technologies:

[0034] Component simplification: In existing technologies, fixing the fixing part 3 requires a separate fixing screw, and connecting the hinge part 4 to the temple of the eyeglasses requires a separate hinge shaft or screw, requiring at least two types of connecting parts. However, this solution uses a coaxial design, requiring only one screw 5 to simultaneously meet the needs of both the fixing part connection and the hinge shaft, thus reducing the number of components and lowering component procurement costs and inventory management difficulties.

[0035] Improved assembly efficiency: Traditional assembly requires two steps: first, fixing the screws at the disconnect slot, and then installing the hinge shaft or screws. This solution completes the fixing of the fixing part 3 and the assembly of the eyeglass temple hinge structure simultaneously by installing screw 5 in one step. The assembly steps are simplified from at least two steps to one step, reducing assembly time. Especially in large-scale production, it can significantly improve the efficiency of assembly line operations.

[0036] Optimized structural compactness: The coaxial arrangement avoids the space occupation problem caused by the separate placement of fixing holes and hinge holes in the traditional structure, making the structural layout of frame 1 more compact.

[0037] The diameter of the hinge hole 41 is larger than the diameter of the fixing hole 31. This dimensional difference creates a precise fit with the structure of the screw 5.

[0038] The screw 5 includes a first screw 51 and a second screw 52 and a screw head 53 coaxially connected to both ends of the first screw 51.

[0039] The diameter of the second screw 52 is smaller than the diameter of the first screw 51, and the diameter of the first screw 51 is smaller than the diameter of the screw head 53.

[0040] The diameter of the first screw 51 is equal to the diameter of the hinge hole 41, and the diameter of the second screw 52 is equal to the diameter of the fixing hole 31.

[0041] The inner wall of the fixing hole 31 on the fixing part 3 away from the hinge part 4 is provided with an internal thread that is threaded to the second screw 52.

[0042] During assembly, the screw 5 is inserted through the hinge hole 41. Since the diameter of the first screw 51 is equal to that of the hinge hole 41, a clearance fit is formed, allowing the screw to pass smoothly into the hinge hole 41. After passing through the hinge hole 41, the second screw 52 of the screw 5 aligns with the fixing hole 31. Because the diameter of the second screw 52 is equal to that of the fixing hole 31, and the inner wall of the fixing hole 31 of the fixing part 3, which is away from the hinge part 4, is provided with an internal thread, the second screw 52 can achieve a threaded connection with this internal thread. When the screw 5 is tightened, the end of the first screw 51 abuts against the end face of the fixing part 3 near the hinge part 4. At this time, the end face of the screw head 53 is spaced apart from the hinge part 4, and the tightened screw 5 forms a fixed connection between the two fixing parts 3.

[0043] There are two hinge parts 4, which are spaced apart.

[0044] The frame 1 is made of metal, and both the fixing part 3 and the hinge part 4 are welded to the frame 1. Common materials include titanium alloy, aluminum alloy, or stainless steel. Metal materials have the characteristics of high strength, good toughness, and wear resistance, which can meet the structural strength and durability requirements of eyeglass frames.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
