Description

Technical Field

[0001] The present application relates to the field of eyeglass component technology, and in particular to a pile head structure and eyeglasses. Background Art

[0002] The frame of existing glasses is generally connected to the temples by a hinge device with a screw, so that the temples and the frame can be folded or unfolded. In order to make the temples more labor-saving when unfolding and folding, most glasses have adopted an elastic hinge structure.

[0003] Existing elastic hinges generally connect the temples and frames with screws, and elastic force is provided by a torsion spring sleeved on the screws. However, loose screws can easily cause the torsion spring to shake, causing the elastic effect of the hinge to fail. In addition, the configuration of the temple hinges requires extremely small screw specifications. Due to the small size of the objects, special tools must be used for assembly or disassembly, making it difficult to assemble or disassemble. Utility Model Content

[0004] In order to reduce the elastic effect and facilitate assembly, the present application provides a pile head structure and glasses.

[0005] The present application provides a pile head structure and glasses that adopt the following technical solutions:

[0006] A pile head structure includes an elastic hinge, which includes a base, a fixed plate plugged into the base, a spring piece sleeved on the fixed plate, and a connecting plate engaged with the fixed plate and rotatably connected. The spring piece is bent and arranged between the base and the connecting plate. The spring piece includes a fixed part abutting the base, a toggle part abutting the connecting plate, and an elastic part connecting the toggle part and the fixed part. Both the fixed part and the toggle part are provided with through holes for the fixed piece to pass through at the same time.

[0007] By adopting the above technical solution, when the connecting plate is rotated, it can abut against the toggle portion, thereby lifting the toggle portion. Under the influence of the elastic portion, the spring piece has accumulated some elastic force at this time. When the connecting plate continues to rotate and reaches a certain angle, the spring piece resets, prompting the connecting plate to rotate to the specified position more quickly, thereby achieving elastic rotation of the connecting plate. The entire elastic hinge structure does not require screws to fix, and there is no loss of elasticity due to loose screws. The assembly process is simpler and faster, effectively improving assembly efficiency.

[0008] Optionally, the fixing plate includes an abutting portion and a connecting portion, the abutting portion is wider than the connecting portion, and the abutting portion abuts against a side of the base away from the elastic plate.

[0009] By adopting the above technical solution, in conjunction with the spring sheet and the connecting plate, the abutting portion can always abut against the side wall of the base, thereby ensuring that the fixing plate is stably inserted into the base and is not easy to fall out of the base, thereby ensuring the stability of the overall structure.

[0010] Optionally, the connecting plate is provided with a travel hole, the connecting portion is provided with a snap-in hole for inserting one end of the connecting plate, the snap-in hole extends to the side wall of the connecting plate, and the connecting portion is located at the end of the snap-in hole away from the abutting portion as a hook foot, and the hook foot is used to be inserted into the travel hole.

[0011] By adopting the above technical solution, the connecting plate can be inserted into the connecting portion along the inner wall of the clamping hole, and the hook foot can be inserted into the travel hole of the connecting plate, thereby achieving mutual engagement and rotation, making it difficult for the connecting plate to fall off from the fixing plate.

[0012] Optionally, the inner wall of the engaging hole close to the hook foot is arc-shaped.

[0013] By adopting the above technical solution, the arc-shaped inner wall makes the inner wall of the travel hole abut against the clamping hole, and the abutting part will form a straight line rather than a surface, so that no interference will occur when the connecting plate rotates, causing it to be unable to rotate.

[0014] Optionally, the width of the hook foot gradually decreases toward the side away from the base, and the side walls on both sides of the hook foot are guide surfaces, and the guide surfaces on both sides are inclined toward one side.

[0015] By adopting the above technical solution, when the connecting plate rotates, the inner wall of the travel hole will not abut against the side wall of the hook foot, causing the connecting plate to be unable to rotate normally, thereby ensuring that the connecting plate can rotate normally.

[0016] Optionally, the opening direction of the bent spring is the same as the extending direction of the locking hole.

[0017] By adopting the above technical solution, when the connecting plate rotates, the moving part of the spring can be more easily lifted up. After rotating to a certain angle, it can ensure that the moving part of the spring has sufficient elastic force to move one end of the connecting plate, thereby quickly resetting the connecting plate.

[0018] Optionally, a clearance hole is formed at one end of the connecting plate close to the clamping hole.

[0019] By adopting the above technical solution, the clearance hole allows a part of the hook foot to be placed in the clearance hole, thereby preventing the end of the connecting plate from abutting against the inner wall of the clearance hole, resulting in a failure in smooth rotation.

[0020] Optionally, the width of the through hole is greater than the width of the connecting portion.

[0021] By adopting the above technical solution, when the toggle part is pushed up, the inner wall of the through hole will not abut against the side wall of the connecting part, causing the toggle part to be unable to be pushed up smoothly, ensuring that the spring piece can continue to generate rebound force to realize automatic resetting of the connecting plate without manual adjustment.

[0022] A pair of glasses, comprising temples, a nose bridge, a frame connected to both sides of the nose bridge, a lens clamped inside the frame, and the above-mentioned pile head structure, wherein the elastic hinge is arranged at one end of the temple, the temple is fixedly connected to the connecting plate, and the base is fixedly connected to the frame or the lens.

[0023] Optionally, the frame and the base are both made of plastic, and the base is provided with a groove for placing the shrapnel.

[0024] By adopting the above technical solution, in order to ensure the supporting effect, the plastic frame and base will have a large thickness, and grooves are provided so that the spring can be placed in the grooves, and the fixing plate can ensure the normal rotation of the elastic hinge.

[0025] In summary, this application has the following beneficial effects:

[0026] 1. By opening a through hole in the spring piece and a snap-in hole on the fixing piece, the elastic hinge can be quickly installed through plug-in cooperation, which is convenient for assembly.

[0027] 2. By setting the spring piece and the fixing piece, no screws are required during the installation of the elastic hinge, thus achieving screw-free installation and preventing elastic failure due to looseness. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] Example 1 of the present application discloses a pile head structure and glasses. Figure 1 The glasses include a nose bridge 3, frames 4 connected to both sides of the nose bridge 3, lenses 5 snapped into the frames 4, and temples 2 connected to opposite sides of the frames 4. A stud structure is connected between the temples 2 and the frames 4. When in use, the stud structure allows the temples 2 to rotate on one side of the frame 4, so that the temples 2 on both sides can be opened, and the glasses can then be worn.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 The head structure includes an elastic hinge 1, which includes a base 11 fixedly connected to the frame 4, a fixing plate 12 plugged into the base 11, a spring 13 sleeved on the fixing plate 12, and a connecting plate 14 engaged and rotatably connected to the fixing plate 12. The connecting plate 14 is used to connect to the temple 2. The frame 4 and base 11 are made of metal, which can achieve a lighter and thinner design, reducing the burden when wearing. The spring piece 13 is bent and arranged between the base 11 and the connecting plate 14. The two ends of the spring piece 13 are respectively abutted against the base 11 and the connecting plate 14. The spring piece 13 includes a fixed portion 131 abutting against the base 11, a toggle portion 132 abutting against the connecting plate 14, and an elastic portion 133 connecting the toggle portion 132 and the fixed portion 131. The fixed portion 131 and the toggle portion 132 are both provided with a through hole 134 for the fixing piece 12 to pass through. The fixing piece 12 includes an abutting portion 121 abutting against the base 11 and a connecting portion 122 penetrating the base 11. The width of the abutting portion 121 is greater than that of the connecting portion 122. The abutting portion 121 abuts against the side of the base 11 facing away from the spring piece 13.

[0036] During assembly, the fixing plate 12 is inserted into the base 11, the spring plate 13 is then sleeved onto the fixing plate 12 along the through hole 134, and finally the connecting plate 14 is snapped into the fixing plate 12. At this point, both sides of the spring plate 13 will abut against both the base 11 and the connecting plate 14, thereby completing the assembly of the elastic hinge 1. Due to the curved configuration of the spring plate 13, the spring plate 13 always has elastic force, and the spring plate 13 continuously releases elastic forces in opposite directions toward the base 11 and the connecting plate 14, respectively. Since the connecting plate 14 is snapped into the fixing plate 12, the fixing plate 12 is driven to move away from the base 11, thereby causing the abutting portion 121 to tightly abut against the base 11, ensuring the stability of the assembled structure.

[0037] When the temple 2 needs to be opened or closed, the temple 2 is rotated to drive the connecting plate 14 to rotate. When the connecting plate 14 rotates, the toggle portion 132 of the spring piece 13 is pushed up. At this time, the spring piece 13 accumulates more elastic force. When the connecting plate 14 continues to rotate to a certain angle, the elastic force of the spring piece 13 will prompt the connecting plate 14 to rotate faster, thereby reaching the specified position and realizing the elastic rotation of the connecting plate 14.

[0038] In the embodiment of the present application, the base 11 is directly fixedly connected to the frame 4, thereby achieving a better fixing effect; in other embodiments, the base 11 can also be directly fixed to the lens 5 to meet the needs of frameless glasses.

[0039] Reference Figure 2 、 Figure 3 The width of the through hole 134 is greater than the width of the connecting portion 122. When the connecting plate 14 rotates, the toggle portion 132 is lifted. Since the width of the through hole 134 is greater than the width of the connecting portion 122, the inner wall of the through hole 134 does not abut against the side wall of the connecting portion 122, which prevents the toggle portion 132 from being lifted normally. This ensures that the connecting plate 14 can rotate normally and that the toggle portion 132 can quickly return to its original position.

[0040] Reference Figure 2 、 Figure 3 The connecting plate 14 is provided with a travel hole 141, and the connecting portion 122 is provided with a snap-in hole 123 for inserting one end of the connecting plate 14. The snap-in hole 123 extends to the side wall of the connecting plate 14 away from the frame 4. The end of the connecting portion 122 located at the snap-in hole 123 away from the abutting portion 121 is a hook foot 124, which is inserted into the travel hole 141. The frame is inserted into the travel hole 141 of the connecting plate 14, and the connecting plate 14 is inserted into the connecting portion 122 along the inner wall of the snap-in hole 123, so that the fixing plate 12 and the connecting plate 14 are mutually engaged and rotated, and the elastic plate 13 abuts against each other, making it difficult for the connecting plate 14 to fall out of the fixing plate 12. The opening direction of the elastic plate 13 after bending is the same as the extension direction of the snap-in hole 123. When the connecting plate 14 rotates, the toggle portion 132 can be more easily lifted up, so that the toggle portion 132 has sufficient elastic force to quickly reset the connecting plate 14.

[0041] Reference Figure 2 、 Figure 3 , the inner wall of the snap-in hole 123 near the hook foot 124 is arc-shaped. The arc-shaped inner wall makes it possible for the connecting plate 14 to form a straight line rather than a surface when the inner wall of the travel hole 141 abuts against the snap-in hole 123 during the rotation of the connecting plate 14, so that line contact is achieved, making the rotation smoother. The width of the hook foot 124 gradually decreases toward the side away from the base 11, and the side walls on both sides of the hook foot 124 are guide surfaces 125, and the guide surfaces 125 on both sides are inclined toward each other. Since the width of the hook foot 124 gradually decreases, when the connecting plate 14 rotates, the inner wall of the travel hole 141 away from the fixing plate 12 will not abut against the side wall of the hook foot 124, causing the connecting plate 14 to be unable to rotate normally, thereby ensuring that the elastic hinge 1 works normally.

[0042] Reference Figure 2 、 Figure 3, the connecting plate 14 is provided with a clearance hole 142 at one end close to the fixing piece 12. During the rotation of the temple 2, the clearance hole 142 prevents the end of the connecting plate 14 from abutting against the inner wall of the clamping hole 123, thereby ensuring the smooth rotation of the connecting plate 14.

[0043] The implementation principle of the pile head structure and glasses of Example 1 of the present application is: when installing, first insert the fixing plate 12 into the base 11 so that the abutting portion 121 abuts against the outer wall of the base 11, then bend the spring plate 13, and sleeve the spring plate 13 on the connecting portion 122 of the fixing plate 12 along the through hole 134, and finally insert the connecting plate 14 into the connecting portion 122 along the snap-fit ​​hole 123, so that the hook foot 124 can be inserted into the travel hole 141, thereby completing the overall installation.

[0044] Example 2 of the present application discloses a pile head structure and glasses, which differs from Example 1 only in that the structure of the base 11 is different. Figure 4 The base 11 defines a groove 111 for placing the spring piece 13, and the fixing piece 12 is inserted through the inner wall of the groove 111. When the frame 4 and the base 11 are made of plastic, in order to ensure support, the thickness of the frame 4 and the base 11 will inevitably increase. In this case, after the fixing piece 12 is inserted into the base 11, there will not be enough space for the spring piece 13 to be installed. Therefore, the base 11 defines a groove 111 for placing the spring piece 13, so that after the fixing piece 12 is inserted into the base 11, the groove 111 provides sufficient space for the spring piece 13 to be placed, thereby realizing the normal rotation of the elastic hinge 1 and ensuring the smooth operation of the elastic hinge 1.

[0045] The implementation principle of the pile head structure and glasses of Example 2 of the present application is: when installing, first insert the fixing plate 12 into the base 11 so that the abutting portion 121 abuts against the outer wall of the base 11, then bend the spring plate 13, and sleeve the spring plate 13 on the connecting portion 122 of the fixing plate 12 along the through hole 134, and finally insert the connecting plate 14 into the connecting portion 122 along the snap-fit ​​hole 123, so that the hook foot 124 can be inserted into the travel hole 141, thereby completing the overall installation.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
