Description

Technical Field

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

[0002] Current eyeglass frames generally use screw-type hinges to connect the temples to the ends. While the structure is mature, screw loosening and detachment are very common during use, especially under frequent opening and closing or external pressure, causing the temples to wobble or even fall off. For users, the small size of the screws also makes repairs extremely inconvenient. Once they come loose in non-professional settings, reassembly is often difficult, and temple replacement requires tools and a stable operating environment. Furthermore, many current so-called "quick-release" structures still rely on screws or spring hinges, resulting in a complex assembly process and insufficient disassembly, failing to truly achieve tool-free, quick temple replacement. With the increasing demand for personalized and modular eyewear, users want to be able to quickly replace temples of different styles and functions for different usage scenarios, such as sports temples, lightweight temples, or decorative temples. Therefore, a screwless, reliable hinge structure that allows for quick temple replacement is particularly necessary. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a screwless hinge structure for eyeglass frames with replaceable temples, which effectively overcomes the shortcomings of existing technologies.

[0004] This utility model is achieved through the following technical solution: a screwless hinge structure for replaceable temples of eyeglass frames, comprising:

[0005] The temple and the end cap are rotatably connected by a hinge structure, the hinge structure comprising:

[0006] A rotating body, which is fixedly connected to the temple of the mirror;

[0007] A rotating groove is formed on the end, and a rotating track groove is also provided on the circumferential surface of the end, the rotating track groove communicating with the rotating groove;

[0008] A notch is provided at the end, and the rotating body on the temple is inserted into the rotating groove through the notch.

[0009] As a preferred technical solution, a connecting section is provided between the rotating body and the temple, and the connecting section passes through the notch to insert the rotating body into the rotating groove.

[0010] As a preferred technical solution, a protruding limiting protrusion is provided at the position of the rotating track groove near the notch.

[0011] As a preferred technical solution, an elastic support pad is provided on the bottom surface of the rotating groove.

[0012] The beneficial effects of this utility model are: By setting a rotating groove, a rotating track groove and an opening notch on the end, and forming a rotating body and connecting section that cooperate with it on one side of the temple, the temple can be directly inserted into the rotating groove through the notch to complete the installation without screws. This simplifies the assembly process and avoids the reliability problems caused by loose or falling screws in traditional screw hinges.

[0013] Meanwhile, the limiting protrusion set near the notch of the rotating track groove effectively blocks the rotating body after the temple is inserted, keeping it stable within the normal opening and closing range, and providing additional limiting protection when under force, thereby improving the durability and resistance to external forces of the entire hinge structure.

[0019] 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.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1As shown, in a specific embodiment of this utility model, the screwless hinge structure of the replaceable temple 1 eyeglass frame mainly consists of the temple 1 and the end 2. The temple 1 and the end 2 are reliably connected by a screwless hinge structure. A fixedly mounted rotating body 3 is provided at the end of the temple 1. This rotating body 3, as a key component for rotation, locking, and limiting, matches the shape of the rotating groove 7 inside the end 2, allowing it to rotate stably within the rotating groove 7 after assembly. To ensure smooth assembly and structural strength, a connecting section 5 is provided between the rotating body 3 and the temple 1. This connecting section 5 is generally elongated or transitional in shape, allowing it to smoothly pass through the notch 4 on the end 2 during assembly. After passing through the end 2, it accurately guides the rotating body 3 into the rotating groove 7, enabling the entire assembly process to be completed without screws or tools.

[0022] End 2, serving as the other side of the hinge structure, has an internal rotating groove 7 that mates with the rotating body 3. The dimensions, width, and depth of the rotating groove 7 correspond to the geometry of the rotating body 3 to ensure smooth rotation within the groove after insertion. To enable a quick-installation insertion method for the temple 1, a notch 4 communicating with the rotating groove 7 is provided on the outer circumferential surface of end 2. This notch 4 provides an entry path for the rotating body 3 during installation. The user simply applies force to press the rotating body 3 into the notch 4, and the rotating body 3 will automatically engage in the rotating groove 7 along the notch 4 and complete the positioning. When the temple 1 is pushed through the notch 4, the connecting section 5 first enters the notch 4 and acts as a guide, subsequently driving the rotating body 3 completely into the rotating groove 7. This not only makes the assembly process more natural but also avoids wear or jamming caused by forced insertion.

[0023] To enhance the stability of the temple 1 during rotation and prevent it from accidentally detaching under external force, a rotating track groove 6 extending circumferentially is provided on the circumferential surface of the end 2. The rotating track groove 6 communicates with the rotating groove 7 and is used to limit the movement path of the rotating body 3 in the left and right opening and closing directions. A protruding limiting protrusion 9 is provided near the track groove position of the notch 4. This limiting protrusion 9 forms a reverse obstruction after the temple 1 is inserted, making it difficult for the rotating body 3 to slide out along the original path. This effectively prevents the temple 1 from loosening due to external pulling or excessive rotation, thereby improving the safety and durability of the overall structure. In actual use, the user can still disassemble the rotating body 3 by using a specific angle and force to move it over the limiting protrusion 9, thus ensuring both quick disassembly and structural stability.

[0024] To improve the feel of the temple 1 when opening and closing and reduce wear caused by hard contact, an elastic support pad 8 is provided on the bottom surface of the rotating groove 7. The elastic support pad 8 can be made of rubber, silicone or other flexible materials. Its main function is to provide elastic support for the rotating body 3. In addition, the elastic support pad can also lift the rotating body, so that the connecting section can only rotate within the rotating track groove defined by the limiting protrusion. When it encounters the limiting protrusion, it cannot disengage. When it is necessary to remove the temple, the rotating body is pressed down, causing the elastic support pad to deform under pressure, which allows the connecting section to separate from the rotating track groove. Then it can be taken out upward through the notch, which is very convenient.

[0025] 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.
