Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to a sliding eyeglass temple rotation structure. Background Technology

[0002] Existing eyeglasses generally consist of an eyeglass frame with two lenses and two temples symmetrically arranged on both sides of the eyeglass frame. There are two connectors on each side of the eyeglass frame that are used to connect to the corresponding temples. The connectors and temples are generally connected by groove insertion and bolt positioning. When not wearing glasses, the two temples are folded and stored in the glasses case. During storage, the temples may shift due to angle or excessive movement, requiring refolding. Also, when not in a case, people often tuck one of the folded temples into their collar to hang the glasses there. However, the temples wobble with the wearer's movements, causing them to shift and lose their hanging function. As the wearer's movements increase, the hanging effect of the partially folded temple gradually decreases until the glasses eventually fall off the collar. Utility Model Content

[0003] The purpose of this invention is to provide a sliding temple rotation structure for eyeglasses to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sliding temple rotating structure for eyeglasses, including a frame, connectors symmetrically and fixedly connected to both ends of the frame, and temples rotatably connected to the other end of the connectors. A rhomboid connecting block is fixedly connected to the other end of the connector. A rhomboid through groove is provided at the top of the rhomboid connecting block. Slots communicating with the inner wall of the rhomboid through groove are provided on the middle of the outer walls of the rhomboid connecting block near the temples and on the middle of the outer wall of the rhomboid connecting block near the frame. Two flexible connecting pieces are integrally provided at the end of the temple near the rhomboid connecting block. The two connecting pieces are arranged in a V-shape. The end of each connecting piece near the rhomboid connecting block passes through the slot and extends into the rhomboid through groove. Two extension blocks are symmetrically arranged at the ends of the connecting pieces located in the rhomboid through groove. The outer wall of the extension block fits and slides against the inner wall of the corresponding rhomboid through groove. The upper and lower outer walls of the connecting piece fit and slide against the upper and lower inner walls of the slot, respectively.

[0005] Furthermore, the included angle of the rhomboid connecting block is arc-shaped, and the cross-section of the extension block is circular.

[0006] Furthermore, the end of the connecting piece is arc-shaped, and the cross-sectional width of the connecting piece is greater than the diameter of the extension block. Both ends of the slot have slides extending towards the inner wall of the diamond-shaped through groove.

[0007] Furthermore, two sets of limiting components are symmetrically arranged on the inner walls of the diamond-shaped through grooves located on the upper and lower sides of the slot. The limiting components include two symmetrical and integrally arranged limiting blocks on the inner wall of the diamond-shaped through grooves. One of the limiting blocks is arranged on the front inner wall of the diamond-shaped through groove away from the frame, and the other limiting block is arranged on the rear inner wall of the diamond-shaped through groove near the frame.

[0008] Furthermore, the length of the limiting block located on the inner wall of the front side of the rhomboid channel from the angle near the temple to the angle of the inner wall of the adjacent rhomboid channel, and the length of the limiting block located on the inner wall of the rear side of the rhomboid channel from the angle away from the temple to the angle of the inner wall of the adjacent rhomboid channel are greater than the diameter of the extension block, and the slot extends to the corner of the outer wall of the front side of the rhomboid connecting block away from the frame.

[0009] Furthermore, the distance between the outer walls on both sides of the limiting block is set to gradually decrease from the diamond-shaped through groove to the end of the limiting block.

[0010] The beneficial effects achieved by this utility model are as follows: By adopting a structural design that combines a diamond-shaped connecting block with a built-in diamond-shaped through groove, and by using a flexible connecting piece with an extension block that slides against the inner wall of the through groove, the extension block can move adaptively along the inner wall of the through groove during the unfolding and folding of the temples. The flexibility of the connecting piece can always keep the extension block in contact with the inner wall of the through groove. With the limiting effect of the diamond-shaped through groove angle on the extension block, displacement and shaking of the temples are effectively prevented in the unfolded or folded state, thus improving the stability of the temple connection.

[0011] By using the arc-shaped design at the included angle of the rhomboid connecting block and the circular design of the cross-section of the extension block, the extension block can slide smoothly along the inner wall of the through groove during the flipping of the eyeglass temple, reducing frictional loss.

[0012] By defining the distance between the included angle of the limiting block and the included angle of the rhomboid through slot, and combining it with the structural design of the slot extending to the corner of the rhomboid connecting block, the temples of the glasses can be flipped outwards to accommodate wearers with wider faces, greatly improving the wearing fit range of the glasses.

[0013] The gradually decreasing spacing between the outer walls of the two sides of the limiting block reduces the smoothness of the extension block when it comes into contact with the limiting block, thus reducing frictional loss. By using an arc-shaped design where the width of the connecting piece cross-section is greater than the diameter of the extension block, and combined with the flexibility of the connecting piece, the connecting piece extending from the extension block can always be engaged in the slot, thereby preventing the end of the connecting piece from coming out of the slot.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1-5 As shown, this utility model discloses a sliding temple rotation structure for eyeglasses, including: a frame 1, connectors 2 symmetrically and fixedly connected to both ends of the frame 1, and temples 3 rotatably connected to the other end of the connectors 2. A rhomboid connecting block 21 is fixedly connected to the other end of the connectors 2. A rhomboid through groove 22 is provided at the top of the rhomboid connecting block 21. Slots 23 communicating with the inner wall of the rhomboid through groove 22 are provided on the middle of the outer walls of the rhomboid connecting block 21 near the temples 3 and on the middle of the outer wall of the rhomboid connecting block 21 near the frame 1. The temples 3 are positioned near... Two flexible connecting pieces 31 are integrally provided at one end of the near-rhomboid connecting block 21. The two connecting pieces 31 are arranged in a V-shape. The end of the connecting piece 31 near the rhomboid connecting block 21 passes through the slot 23 and extends into the rhomboid through groove 22. The end of the connecting piece 31 located in the rhomboid through groove 22 is symmetrically provided with two extension blocks 32. The outer wall of the extension block 32 fits against the inner wall of the corresponding side rhomboid through groove 22 and is slidably connected. The upper and lower outer walls of the connecting piece 31 fit against the upper and lower inner walls of the slot 23 and are slidably connected.

[0017] Furthermore, such as Figure 2-5 As shown, the included angle of the rhomboid connecting block 21 is arc-shaped, and the cross-section of the extension block 32 is circular.

[0018] Furthermore, such as Figure 3-5 As shown, the end of the connecting piece 31 is arc-shaped, and the cross-sectional width of the connecting piece 31 is greater than the diameter of the extension block 32. Both ends of the slot 23 have slides 25 extending towards the inner wall of the rhomboid through groove 22.

[0019] Furthermore, such as Figure 2-5As shown, two sets of limiting components are symmetrically arranged on the inner walls of the rhomboid through grooves 22 located on the upper and lower sides of the slot 23. The limiting components include two symmetrical and integrally arranged limiting blocks 24 on the inner walls of the rhomboid through grooves 22. One limiting block 24 is arranged on the front inner wall of the rhomboid through groove 22 away from the frame 1, and the other limiting block 24 is arranged on the rear inner wall of the rhomboid through groove 22 near the frame 1.

[0020] Based on the above structure, such as Figure 1-5 As shown, when people wear glasses, (such as...) Figure 3 (As shown in the unfolded state), the extension blocks 32 at the ends of the two connecting pieces 31 within the same rhomboid groove 22 respectively abut against the two lateral angles of the rhomboid groove 22. When the temples 3 are folded, the two temples 3 flip to opposite sides. The extension block 32 on the side closer to the frame 1 moves along the front inner wall of the rhomboid groove 22 on the side closer to the frame 1 towards the angle of the rhomboid groove 22 on the side closer to the connector 2. At the same time, the extension block 32 on the side away from the frame 1 moves along the rear inner wall of the rhomboid groove 22 on the side away from the frame 1 towards the angle of the rhomboid groove 22 on the side closer to the temple 3, until the temples 3 are completely folded (as shown in the unfolded state). Figure 3 (As shown in the folded state), at this time, the outer wall of the extension block 32 that was originally close to the frame 1 abuts against the angle of the rhomboid through groove 22 that was close to the connector 2, and the outer wall of the extension block 32 that was originally far away from the frame 1 abuts against the angle of the rhomboid through groove 22 that was close to the temple 3. During the flipping of the temple 3, because the distance between the two symmetrical angles in the rhomboid groove 22 is greater than the distance between the middle parts of the two symmetrical inner walls in the rhomboid groove 22, the distance between the extension blocks 32 at the ends of the two connecting pieces 31 gradually decreases and then gradually increases during the flipping of the temple 3. For example, when the ends of the two connecting pieces 31 are aligned with the middle parts of the two symmetrical inner walls in the rhomboid groove 22, the distance between the extension blocks 32 at the ends of the two connecting pieces 31 is the shortest. When the ends of the two connecting pieces 31 abut against the two symmetrical angles in the rhomboid groove 22, the distance between the extension blocks 32 at the ends of the two connecting pieces 31 is the largest. At the same time, the distance between the ends of the two connecting pieces 31 on the same temple 3 changes with the distance between the extension blocks 32 at the ends of the two connecting pieces 31. Meanwhile, due to the toughness of the connecting piece 31, during the movement of the extension block 32, the connecting piece 31 always applies a force to the outside of the rhomboid connecting block 21 on the extension block 32, thereby keeping the outer wall of the extension block 32 in contact with the inner wall of the rhomboid through groove 22. Especially when the outer wall of the extension block 32 is in contact with the inner wall of the rhomboid through groove 22, the angle of the inner wall of the rhomboid through groove 22 limits the extension block 32, thereby limiting the eyeglass temple 3, thus preventing the eyeglass temple 3 from displacing and shaking in the unfolded and folded states. Furthermore, since the cross-sectional width of the connecting piece 31 is greater than the diameter of the extension block 32, the connecting piece 31 extending from the extension block 32 can always be engaged in the slot 23, thereby preventing the end of the connecting piece 31 from disengaging from the slot 23.

[0021] Furthermore, such as Figure 2-5 As shown, in order to accommodate wearers with a wider face, the length of the limiting block 24 on the front inner wall of the diamond-shaped channel 22 from the angle near the temple 3 to the angle of the adjacent inner wall of the diamond-shaped channel 22 and the length of the limiting block 24 on the rear inner wall of the diamond-shaped channel 22 from the angle away from the temple 3 to the angle of the adjacent inner wall of the diamond-shaped channel 22 are greater than the diameter of the extension block 32. The slot 23 extends to the corner of the front outer wall of the diamond-shaped connecting block 21 away from the frame 1. Based on the above structure, such as Figure 1-5 As shown, when used by a wearer with a wider face, the user flips the two temples 3 of the glasses in the unfolded state (at which point, the extension blocks 32 at the ends of the two connecting pieces 31 in the same rhomboid groove 22 respectively abut against the two lateral angles of the rhomboid groove 22) to the side away from each other. At this time, the extension block 32 on the side closer to the frame 1 moves along the rear inner wall of the rhomboid groove 22 on the side closer to the frame 1 towards the angle between the limiting block 24 on the side closer to the temple 3 in the rhomboid groove 22. At the same time, the extension block 32 on the side away from the frame 1 moves along the rhomboid groove 22 towards the angle between the limiting block 24 on the side closer to the temple 3. The inner front wall of the eyeglass frame 1 moves towards the angle between the limiting block 24 on the side away from the temple 3 in the diamond-shaped groove 22. The outer walls of the extension blocks 32 at the ends of the two connecting pieces 31 abut against the angle between the two limiting blocks 24 in the same diamond-shaped groove 22, until the outer wall of the connecting piece 31 on the side away from the eyeglass frame 1 abuts against the inner wall of the slot 23 at the end away from the eyeglass frame 1, thereby completing the complete outward expansion of the two temples 3. In the state of complete outward expansion of the temples 3, the distance between the ends of the two connecting pieces 31 in the same diamond-shaped groove 22 is shortened. The wearer then puts the glasses on their face and gradually reduces the distance between the two temples 3 away from the frame 1. During this process, the extension block 32, which originally abutted the angle between the outer wall and the limiting block 24, moves to the lateral angle on the corresponding side inside the rhomboid groove 22. During this process, because the connecting piece 31 is resilient, the connecting piece 31 rebounds, keeping the outer wall of the extension block 32 always abutting the inner wall of the rhomboid groove 22, until the rear end of the outer wall of the temple 3 near the frame 1 is in contact with the wearer's skin.

[0022] Furthermore, such as Figure 2-5 As shown, the distance between the outer walls on both sides of the limiting block 24 is gradually reduced from the diamond-shaped through groove 22 to the end of the limiting block 24.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
