Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to a hinge and eyeglasses. Background Technology

[0002] The hinge of eyeglasses is the structure that connects the temples to the frame, enabling a rotatable connection between them. In traditional technology, such as the utility model patent with patent number 202322956664.2, a flexible eyeglass hinge structure is disclosed. This flexible eyeglass hinge structure includes: an eyeglass post, a spring, and eyeglass temples. The front end of the eyeglass post has a post mounting hole, and the outer side of the front end of the eyeglass post has a first structural surface and a second structural surface. The front end of the eyeglass temple is a U-shaped structure composed of an upper connecting piece and a lower connecting piece. The upper and lower connecting pieces have a post fixing connection hole and a spring connecting hole passing through them. The bottom of the U-shaped structure of the eyeglass temple has a third structural surface, and the front end of the spring... The system features a front structural surface and a rear end with a spring fixing hole and a rear structural surface. The spring is inserted into the U-shaped structure of the temple. A spring screw is inserted into the fixing hole and connecting hole to secure the spring and temple. The spring design allows the temple to open outwards at a certain angle, providing a rebound force and increasing wearing comfort. However, in actual use, the temple relies on the spring for positioning. After repeated rotations, the spring may lose its elasticity due to aging, resulting in a loss of rebound force and thus failing to limit the temple's rotation range. This presents a technical problem of poor hinge positioning reliability. Utility Model Content

[0003] Therefore, it is necessary to provide a hinge and eyeglasses to address the technical problem of poor hinge positioning reliability.

[0004] A hinge includes: a transition block and a tailstock. The transition block has a rotating hole and a limiting groove. The limiting groove and the rotating hole are coplanar and the limiting groove extends along a preset arc trajectory. The central axis of the arc trajectory of the limiting groove overlaps with the axis of the rotating hole. The two ends of the limiting groove have a first end and a second end, respectively. The tailstock includes a base, a rotating column, and a limiting column. The base has a guide surface. The rotating column and the limiting column are spaced apart on the guide surface. The rotating column is rotatably disposed in the rotating hole, and the limiting column is movably disposed in the limiting groove.

[0005] The adapter block has a first use position and a second use position. When the adapter block is in the first use position, the limiting post abuts against the first end. When the adapter block is in the second use position, the limiting post contacts the second end.

[0006] In one embodiment, the tailstock further includes a combination pad mounted on the rotating column to space the adapter block and the rotating column.

[0007] In one embodiment, the combined pad includes a collar and a washer ring. The collar is sleeved on the rotating column and located within the rotating hole, and the washer ring is disposed between the adapter block and the guide surface.

[0008] In one embodiment, the composite pad is a metal composite pad.

[0009] In one embodiment, the tailstock further includes a flat pad that is fitted onto the limiting post and located between the adapter block and the guide surface.

[0010] In one embodiment, the tailstock further includes a fixing member connected to the rotating column to prevent the adapter block from disengaging from the rotating column along the axis of the rotating column.

[0011] In one embodiment, the base includes a body and a connecting block, the body having a through hole and the connecting block having a connecting hole corresponding to the position of the through hole.

[0012] In one embodiment, the seat further includes a limiting rib, which is connected to the body and forms a fixed space with the body. The connecting block is fixedly installed in the fixed space and abuts against the limiting rib and the body.

[0013] In one embodiment, the adapter block is provided with an oil reservoir located on the side of the adapter block near the guide surface.

[0014] The beneficial effects of the hinge provided in this application are as follows: the adapter block is provided with a rotating hole and a limiting groove, the central axis of the arc trajectory of the limiting groove overlaps with the axis of the rotating hole, and the tailstock includes a base, a rotating column and a limiting column. The rotating column is rotatably disposed in the rotating hole, and the limiting column is movably disposed in the limiting groove. The adapter block rotates relative to the tailstock through the cooperation of the rotating column and the rotating hole. The limiting column moves within the limiting groove, and the first and second ends of the limiting groove limit the rotation range of the adapter block, so that the adapter block is restricted to a stable switching between two use positions. This effectively avoids the situation where the hinge loses its limitation on the rotation range of the temple due to aging, thereby improving the limiting reliability of the hinge.

[0015] A pair of eyeglasses includes temples, a frame, and the hinge described in any one of the above, wherein the temples are connected to the adapter block, and the frame is connected to the tailpiece.

[0016] The beneficial effects of the eyeglasses provided in this application are as follows: by adopting the aforementioned hinge, the rotation range of the temples relative to the frame can be stably controlled, the opening and closing angle of the temples can be reasonably limited, and the clamping force can be weakened or even lost due to excessive opening of the temples. At the same time, the temples can be prevented from being unable to properly fit the frame due to excessive folding, thus preventing the temples from accidentally pressing against the lens surface and causing scratches or wear on the lens. This effectively extends the service life of the eyeglasses and improves the overall performance and comfort of the eyeglasses. Attached Figure Description

[0031] like Figure 1 As shown, it is the hinge 100 of this utility model.

[0032] like Figures 1 to 2 As shown, the hinge 100 includes: a transition block 10 and a tailstock 20, wherein, as Figure 3 As shown, the adapter block 10 is provided with a rotating hole 11 and a limiting groove 12. The limiting groove 12 and the rotating hole 11 are coplanar, and the limiting groove 12 extends along a preset arc trajectory. The central axis of the arc trajectory of the limiting groove 12 overlaps with the axis of the rotating hole 11. The two ends of the limiting groove 12 are respectively provided with a first end 121 and a second end 122, as shown. Figure 2 As shown, the tailstock 20 includes a base 21, a rotating column 22, and a limiting column 23. The base 21 has a guide surface 211. The rotating column 22 and the limiting column 23 are spaced apart on the guide surface 211. In use, the rotating column 22 is rotatably disposed in the rotating hole 11, and the limiting column 23 is movably disposed in the limiting groove 12. The adapter block 10 has a first use position and a second use position, as shown. Figure 1 As shown, when the adapter block 10 is in the first use position, the limiting post 23 abuts against the first end 121, as... Figure 4 As shown, when the adapter block 10 is in the second use position, the limiting post 23 contacts the second end 122. The adapter block 10 is provided with a rotating hole 11 and a limiting groove 12. The central axis of the arc trajectory of the limiting groove 12 overlaps with the axis of the rotating hole 11. The tailstock 20 includes a seat body 21, a rotating post 22 and a limiting post 23. The rotating post 22 is rotatably disposed in the rotating hole 11, and the limiting post 23 is movably disposed in the limiting groove 12. The adapter block 10 rotates relative to the tailstock 20 through the cooperation of the rotating post 22 and the rotating hole 11. The limiting post 23 moves in the limiting groove 12, and the first end 121 and the second end 122 at both ends of the limiting groove 12 limit the rotation range of the adapter block 10. This allows the adapter block 10 to be stably switched between the two use positions, effectively preventing the hinge 100 from losing its limitation on the rotation range of the temple due to aging, and achieving the purpose of improving the limiting reliability of the hinge 100.

[0033] The following text, combined with Figures 1 to 4 The hinge 100 described above will be further explained.

[0034] To further improve the service life and performance of hinge 100, such as Figure 3 As shown, the adapter block 10 is provided with an oil reservoir 13. The oil reservoir 13 is located on the side of the adapter block 10 near the guide surface 211. The oil reservoir 13 can store lubricating oil. During the rotation of the hinge 100, the lubricating oil can seep out from the oil reservoir 13 and lubricate the contact parts such as the guide surface 211 between the adapter block 10 and the tailstock 20 and between the rotating column 22 and the rotating hole 11. This reduces the friction and wear between the parts, thereby reducing the rotational resistance of the adapter block 10 and making the hinge 100 rotate more smoothly, thus further improving the service life and working performance of the hinge 100.

[0035] To improve the user experience of adapter block 10, such as Figure 2 As shown, the tailstock 20 also includes a combination pad 24, which is installed on the rotating column 22 to separate the adapter block 10 and the rotating column 22. The combination pad 24 can effectively prevent the adapter block 10 from directly contacting the rotating column 22, reducing friction and wear between them and extending the service life of the hinge 100. At the same time, the combination pad 24 can also effectively reduce the contact area between the adapter block 10 and the rotating column 22, thereby reducing the friction between the adapter block 10 and the rotating column 22, making the adapter block 10 more stable and smooth during rotation, and achieving the purpose of improving the user experience of the adapter block 10.

[0036] To further enhance the user experience of adapter block 10, such as Figure 2 As shown, the combination pad 24 includes a collar 241 and a washer 242. The collar 241 is sleeved on the rotating column 22 and located inside the rotating hole 11. The washer 242 is located between the adapter block 10 and the guide surface 211. Through the cooperation of the collar 241 and the washer 242, the different contact parts between the adapter block 10 and the rotating column 22 can be more precisely protected and spaced. The collar 241 located inside the rotating hole 11 can effectively reduce the contact area between the rotating column 22 and the hole wall of the adapter block 10, thereby improving the smoothness of the rotation of the adapter block 10 relative to the rotating column 22. The washer 242 located between the adapter block 10 and the guide surface 211 can also effectively prevent the adapter block 10 and the guide surface 211 from directly rubbing against each other, thereby effectively reducing the contact area between the adapter block 10 and the guide surface 211, thereby improving the smoothness of the rotation of the adapter block 10 relative to the rotating column 22, so as to further improve the user experience of the adapter block 10.

[0037] In order to improve the reliability and operational stability of the hinge 100, the combination pad 24 is a metal combination pad 24. The metal combination pad 24 has high strength and wear resistance, and can withstand greater friction and pressure. Compared with combination pads 24 made of other materials, it is more adaptable to the working environment of the hinge 100 during frequent opening and closing, thereby further extending the service life of the hinge 100 and achieving the purpose of improving the reliability and operational stability of the hinge 100.

[0038] To improve the rotational stability of the adapter block 10, such as Figure 2 As shown, the tailstock 20 also includes a flat pad 25, which is sleeved on the limiting post 23 and located between the adapter block 10 and the guide surface 211. The flat pad 25 can further reduce the friction between the adapter block 10 and the guide surface 211 of the tailstock 20 at the limiting post 23, making the limiting post 23 rotate more smoothly and achieving the purpose of improving the rotational stability of the adapter block 10.

[0039] To improve the service life and safety of hinge 100, tailstock 20 also includes a fastener (not shown). The fastener is a screw and is connected to rotating post 22. It is used to prevent the adapter block 10 from detaching from rotating post 22 along the axis of rotating post 22. The presence of the fastener ensures a stable connection between adapter block 10 and rotating post 22, preventing adapter block 10 from detaching from rotating post 22 along the axis of rotating post 22 due to external force during use. This ensures the integrity and reliability of hinge 100 structure and avoids hinge 100 failure due to adapter block 10 falling off, thereby improving the service life and safety of hinge 100.

[0040] To improve the ease of maintenance of the base 21, such as Figure 2 As shown, the base 21 includes a body 212 and a connecting block 213. The body 212 is provided with a through hole 214, and the connecting block 213 is provided with a connecting hole 215 corresponding to the position of the through hole 214. The separate design of the body 212 and the connecting block 213, as well as the setting of the through hole 214 and the connecting hole 215, facilitates the connection of the connecting block 213 to the frame first, and then the screws pass through the through hole 214 and are threadedly connected to the connecting hole 215 to realize the connection between the body 212 and the connecting block 213, thereby improving the installation convenience and flexibility of the base 21 and achieving the purpose of improving the maintenance convenience of the base 21.

[0041] To improve the overall reliability of hinge 100, such as Figure 2As shown, the seat 21 also includes a limiting rib 216, which is connected to the body 212 and forms a fixed space 217 with the body 212. The connecting block 213 is fixedly installed in the fixed space 217 and abuts against the limiting rib 216 and the body 212. The fixed space 217 formed by the limiting rib 216 and the body 212 can position and fix the connecting block 213, making the installation of the connecting block 213 more stable. The abutment between the connecting block 213 and the limiting rib 216 and the body 212 increases the contact area and friction between the connecting block 213 and the seat 21, further improving the stability of the seat 21 structure and preventing the body 212 from shifting or loosening during use, thereby improving the overall reliability of the hinge 100.

[0042] A pair of eyeglasses includes temples, a frame, and a hinge 100 for any of the above. The temples are connected to an adapter block 10, and the frame is connected to a tailpiece 20. By using the hinge 100, the rotation range of the temples relative to the frame can be stably controlled, and the opening and closing angle of the temples can be reasonably limited. This avoids the situation where the clamping force weakens or even disappears due to the temples being over-opened. At the same time, it avoids the situation where the temples cannot properly fit the frame due to excessive folding, thus preventing the temples from accidentally pressing against the lens surface and causing scratches or wear on the lens. This effectively extends the service life of the eyeglasses and improves the overall performance and comfort of the eyeglasses.

[0043] When the hinge 100 provided in this application is used, the adapter block 10 rotates around the rotating column 22 when the temple is rotated, and the limiting column 23 moves within the limiting groove 12. When the limiting column 23 abuts against the first end 121 or the second end 122 of the limiting groove 12, the temple reaches the corresponding limit position, thus effectively limiting the rotation range of the temple. At the same time, the combination pad 24, the flat pad 25 and the lubricating oil in the oil reservoir 13 ensure the smoothness and stability of the hinge 100 rotation, reduce wear between components, and extend the service life of the hinge 100 and the glasses.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
