Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an eyeglasses hinge and eyeglasses. Background Technology

[0002] Eyeglass hinges are connecting components in the eyeglass structure, located on both sides of the frame. Their primary function is to connect the temples to the frame, allowing the temples to open and close flexibly. They are typically made of metal to ensure durability and stability. By rotating the hinges, users can easily unfold or fold the eyeglasses for convenient carrying and storage.

[0003] For example, Chinese Patent No. CN210155444U discloses a novel eyeglass hinge, which consists of a hinge base and a hinge component. The hinge base is used to fix the eyeglass frame, and the hinge component is used to fix the eyeglass temple. The hinge base is provided with a double-piece hinge assembly with a locking distance, and the hinge component is provided with a single-piece hinge assembly. The locking distance of the single-piece hinge assembly is adapted to that of the double-piece hinge assembly. The single-piece hinge assembly is correspondingly hinged to the locking distance of the double-piece hinge assembly by a pin. The hinge component is provided with a flat strip-shaped connecting part that is horizontally embedded and fixed in the eyeglass temple. The upper surface and the lower surface of the strip-shaped connecting part are provided with an anti-detachment structure to prevent the strip-shaped connecting part from axially detaching from the eyeglass temple when it is fixed in the eyeglass temple.

[0004] With the continuous progress and innovation in the eyewear industry, eyeglasses, while ensuring their basic functions are perfected, have gradually incorporated a large number of fashionable design elements, making them not only tools to aid vision but also fashion accessories. Specifically, various patterns, brand logos, or unique color schemes have been added to the outer part of the temples, aiming to meet consumers' personalized and diverse visual aesthetic needs, so that each pair of glasses can show a unique style and taste.

[0005] However, while current eyewear designs have made breakthroughs in fashion, the patterns, logos, or color schemes on the outer temples are often limited, failing to offer flexibility in adapting to changes in user preferences or occasions. Their functionality is relatively singular, making it difficult to meet the diverse needs of users in different situations. Utility Model Content

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

[0022] like Figures 1-6As shown, this embodiment discloses an eyeglass hinge, including a hinge body. The hinge body includes a connector 3 connected to the temple 1 and a functional rod 4 slidably connected to and rotatable with the temple 1. The functional rod 4 has multiple functional surfaces 41 arranged circumferentially. The bottom of the connector 3 is fixedly connected to the temple 1 by, but not limited to, glue. In this embodiment, the functional rod 4 is a quadrangular prism structure with four functional surfaces 41. Different patterns, logos, or color schemes can be set on different functional surfaces 41.

[0023] A positioning device for positioning the functional surface 41 is provided between the functional rod 4 and the connecting member 3. The positioning device includes a positioning component 5 disposed between the functional rod 4 and the connecting member 3, and a first elastic component disposed between the functional rod 4 and the temple 1. The sliding of the functional rod 4 controls the opening and closing of the positioning component 5. The first elastic component provides a pre-tightening force to the positioning component 5. The positioning component 5 is used for positioning the functional surface 41 after it is fixed. When it is necessary to rotate the functional rod 4 to change the functional surface 41, the pre-tightening force needs to overcome the elastic force of the first elastic component to separate the positioning component 5. After the functional surface 41 is changed, the first elastic component can reset to provide the pre-tightening force.

[0024] like Figure 2 , Figure 6 As shown, the positioning component 5 includes a plurality of positioning grooves 51 arranged circumferentially on the connector 3, and at least one positioning protrusion 52 arranged on the functional rod 4 and adapted to the positioning grooves 51. Specifically, in this embodiment, four positioning grooves 51 and positioning protrusions 52 are provided. By engaging the positioning protrusions 52 into the positioning grooves 51, the rotational positioning of the functional rod 4 can be achieved.

[0025] In this embodiment, the first elastic component includes a first spring 6 disposed between the functional rod 4 and the temple 1. The functional rod 4 is slidably sleeved on the temple 1, and the first spring 6 is interference-fitted with the temple 1 and the functional rod 4. When the functional rod 4 slides downward relative to the temple 1, the friction between the first spring 6 and the functional rod 4 and the temple 1 causes the first spring 6 to stretch slightly until the positioning protrusion 52 disengages from the positioning groove 51, at which point the functional rod 4 can be rotated. When released, the elastic force generated by the return of the first spring 6 causes the positioning protrusion 52 to automatically engage with the positioning groove 51.

[0026] In addition to being positioned between the function lever 4 and the temple 1, the first spring 6 can also be positioned below the function lever 4 and connected to the temple 1. In this way, when the function lever 4 slides downward, it will compress the first spring 6, and when the first spring 6 returns to its original position, it will also cause the positioning protrusion 52 to automatically engage with the positioning groove 51.

[0027] To limit the bottom of the functional rod 4, in this embodiment, a limiting block 7 is slidably disposed on the temple 1. The limiting block 7 is located at the end of the functional rod 4 away from the connector 3, and the limiting block 7 and the functional rod 4 are rotatably connected, so it will not affect the sliding of the functional rod 4.

[0028] like Figure 5 As shown, a limiting structure (sliding groove slider limiting structure) is also provided between the temple 1 and the limiting block 7. Under the action of the limiting structure, the temple 1 and the limiting block 7 can only slide and fix their displacement relative to each other, thus cooperating with the sliding of the functional rod 4.

[0029] like Figure 1 , Figure 3 As shown, the hinge body also includes a hinge assembly for connecting the connector 3 and the frame 2. The hinge assembly includes a connecting rod 8 slidably disposed on the connector 3, a mounting groove 31 disposed within the connector 3, and a second elastic component installed within the mounting groove 31 and connected to the connecting rod 8. The top of the connecting rod 8 is rotatably connected to the frame 2. The rotation between the connecting rod 8 and the frame 2 enables the frame 2 and temple 1 to unfold and fold. When the frame 2 and temple 1 are unfolded or folded, the second spring 11 assembly always provides elastic force. Under the action of this elastic force, the frame 2 and temple 1 will not easily change state when in the unfolded or folded state (the state change can only be made by the user actively applying external force), thus making the state more stable.

[0030] When the frame 2 and temple 1 are switched, a rotation limiting groove 32 is provided at the end of the connector 3 near the frame 2 to limit the rotation of the frame 2. Under the action of the rotation limiting groove 32, the frame 2 can rotate within a 90° range. When the frame 2 rotates within the rotation limiting groove 32 and the state is switched, the connecting rod 8 will be lifted upward by a certain displacement and will also have a certain offset to the left and right. Therefore, a movable limiting structure is provided between the connector 3 and the connecting rod 8.

[0031] like Figure 4 As shown, the movable limiting structure includes a movable groove 9 on the connecting rod 8 and a top block 10 on the connecting member 3 extending into the movable groove 9. The movable groove 9 has a movable space for the top block 10 to move. This movable space can adapt to the movement state between the connecting rod 8 and the connecting member 3 during state transition. The top block 10 and the movable groove 9 have a V-shaped structure.

[0032] Furthermore, the second elastic component includes a second spring 11 sleeved on the connecting rod 8, and a limiting sleeve 12 disposed within the mounting groove 31 and through which the connecting rod 8 passes. The second spring 11 is located between the limiting sleeve 12 and the bottom end of the connecting rod 8, and the limiting sleeve 12 and the mounting groove 31 are in clearance fit (e.g., Figure 5As shown, a sliding block limiting structure is also provided between the limiting sleeve 12 and the mounting groove 31. When the frame 2 is rotated and the frame 2 and temple 1 are folded, the connecting rod 8 is pulled up during the process, which can further compress the second spring 11. The elastic force generated by the second spring 11 can make the folded state difficult to change on its own.

[0033] According to another embodiment of the present invention: This embodiment discloses a pair of glasses, including a frame 2, temples 1, lenses disposed on the frame 2, and a glasses hinge for connecting the frame 2 and temples 1. The glasses hinge adopts the glasses hinge of Embodiment 1, which allows the outer side of the entire temple 1 to display different logos or color schemes, etc., making it versatile. At the same time, when the frame 2 and temples 1 are in an unfolded or folded state, they will not easily change state, making it convenient for the use and storage of glasses.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
