Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, and in particular to a limiting structure for an eyeglass frame. Background Technology

[0002] Eyeglasses, as a common vision correction tool, can effectively correct various vision problems such as myopia, hyperopia, astigmatism, presbyopia, strabismus, and amblyopia. Eyeglasses generally consist of lenses and frame connectors, primarily used to improve vision, protect the eyes, or as a decorative item. With the improvement of people's living standards and changes in aesthetic concepts, eyeglasses are no longer just functional tools; more and more people are beginning to regard them as fashion accessories, and the shape of the lenses and the style of the frames have become important factors when choosing eyeglasses. The connecting part of the frame, as one of the most critical structures, not only bears the function of connecting the frame and temples but also needs to ensure the comfort and long-term durability of the glasses.

[0003] The connecting parts of existing eyeglass frames are usually made of rigid materials. When the glasses are unfolded or folded, friction occurs between the upper and lower parts of the material at the connection. As the usage time increases, this friction will cause wear on the connecting parts, increase the resistance during folding and unfolding, and thus affect the smoothness of the eyeglass frame and shorten its service life.

[0004] Therefore, a limiting structure for eyeglasses frames is proposed to solve the above problems. Utility Model Content

[0005] The main purpose of this invention is to provide a limiting structure for eyeglass frames, which aims to solve the problem that existing eyeglass frames suffer severe wear at the connection points when unfolded or folded, affecting smoothness of use and service life.

[0006] To achieve the above-mentioned utility model objectives, this utility model proposes a limiting structure for an eyeglass frame, including a frame connector and temples. The temples and the frame connector are connected by a hinge, the hinge including a snap-fit ​​element and a rotating shaft. Both the frame connector and the temples are connected to the rotating shaft, and the snap-fit ​​element snaps onto the rotating shaft.

[0007] A shim is provided between the temple and the rotating shaft, and the shim is configured to reduce friction.

[0008] Furthermore, a gap is provided at the connection between the temple and the rotating shaft for the installation of the gasket, and the gasket protrudes from the opening sidewall of the gap.

[0009] Furthermore, the gasket is a T-shaped rubber sheet.

[0010] Furthermore, the rotating shaft is provided with an annular groove, and the snap-fit ​​component is rotatably connected to the annular groove.

[0011] Furthermore, the temple includes a first connecting portion and a second connecting portion, both of which are provided with connecting holes;

[0012] Wherein, when the snap-fit ​​component is inserted into the connecting hole, the connecting hole and the annular groove are aligned.

[0013] Furthermore, the first connecting portion and the second connecting portion together form a U-shaped body.

[0014] Beneficial effects:

[0015] This utility model discloses a limiting structure for an eyeglass frame, comprising a frame connector and temples. The temples and frame connector are connected by a hinge, which includes a snap-fit ​​component and a rotating shaft. Both the frame connector and temples are connected to the rotating shaft, with the snap-fit ​​component engaging with the shaft. A gasket is provided between the temples and the rotating shaft to reduce friction.

[0031] Reference Figures 1 to 4 This utility model discloses a limiting structure for an eyeglass frame, comprising a frame connector 100 and a temple 200. The temple 200 and the frame connector 100 are connected by a hinge 300. The hinge 300 includes a snap-fit ​​element 310 and a rotating shaft 320. Both the frame connector 100 and the temple 200 are connected to the rotating shaft 320, and the snap-fit ​​element 310 is snapped onto the rotating shaft 320.

[0032] A shim 500 is provided between the temple 200 and the rotating shaft 320, and the shim 500 is configured to reduce friction.

[0033] The temple 200 is made of pure titanium.

[0034] The limiting structure design of this eyeglass frame aims to solve the wear problem caused by friction between the temples 200 and the frame connector 100. In this embodiment, the temples 200 are made of pure titanium. Pure titanium has high hardness and good corrosion resistance, but during repeated unfolding and folding, friction between pure titanium materials can easily lead to wear, thus affecting the service life of the eyeglasses. To solve this problem, a shim 500 is added between the temples 200 and the rotating shaft 320. The shim 500 reduces friction, minimizes wear, ensures smooth use of the connection, and extends the durability of the product.

[0035] In this design, the frame connector 100 and the temple 200 are connected by a hinge 300, which consists of a snap-fit ​​element 310 and a rotating shaft 320. The frame connector 100 and the temple 200 rotate via the rotating shaft 320, which serves as a support and connection in the hinge 300. The snap-fit ​​element 310 is used to fix the rotating shaft 320, ensuring that the frame and temple 200 do not loosen during folding and unfolding. To reduce friction between the temple 200 and the rotating shaft 320, a shim 500 is placed between them. The design of the shim 500... The purpose is to minimize the direct contact between the temple 200 and the rotating shaft 320, thereby reducing friction and avoiding wear caused by friction between pure titanium materials. By setting a shim 500 between the temple 200 and the rotating shaft 320, direct metal-to-metal friction is reduced, significantly lowering the coefficient of friction between the frame connector 100 and the temple 200. The use of the shim 500 effectively reduces wear and avoids damage or unevenness of the contact parts caused by long-term friction of pure titanium materials, so that the eyeglass frame can still maintain smooth unfolding and folding functions even after long-term use.

[0036] When the user unfolds the eyeglass frame, the frame connector 100 and the temple 200 rotate via the rotating shaft 320. At this time, the pad 500 reduces friction between the rotating shaft 320 and the temple 200, ensuring a smooth connection between the frame and the temple 200. During the unfolding process, the pad 500 buffers the friction of the hinge, preventing excessive wear caused by direct contact between the pure titanium materials, making the unfolding action smoother and reducing the impact of wear. When the user folds the eyeglasses after use, the rotating shaft 320 between the frame connector 100 and the temple 200 also acts as a hinge. The friction during the folding process is effectively controlled by the pad 500, reducing the possibility of jamming or inability to fold smoothly due to excessive friction.

[0037] The connection between the temple 200 and the rotating shaft 320 is provided with a gap for the installation of the gasket 500. The gasket 500 is inserted into the gap and protrudes from the opening sidewall of the gap.

[0038] The gasket 500 is a T-shaped rubber sheet.

[0039] The material chosen for the gasket 500 is a T-shaped rubber sheet, which has good elasticity, wear resistance, and adaptability. This effectively reduces friction between the rotating shaft 320 and the temple 200, thereby improving the performance and durability of the eyeglass frame. The T-shaped structure of the gasket 500 provides better fixation and stability. Specifically, a gap is provided at the connection between the rotating shaft 320 and the temple 200. This gap is designed to accommodate the T-shaped rubber sheet. When the frame and temple 200 are unfolded or folded, the gasket 500 is installed within this gap, with both sides of the T-shaped structure contacting the contact surfaces of the rotating shaft 320 and the temple 200, respectively. The rubber material of the gasket 500 provides elasticity, enabling it to act as a shock absorber and buffer in the friction area, significantly reducing the generation of friction. The T-shaped design ensures that the gasket 500 will not shift during use, while avoiding direct contact friction between the gasket 500 and the rotating shaft 320 or the temple 200, further reducing wear and extending service life. In addition, by having the gasket 500 protrude from the sidewall of the gap opening, this embodiment ensures that the gasket 500 will not shift or fall off during the use of the eyeglass frame, helping to keep the gasket 500 in the correct position at all times, ensuring that it exerts its maximum effect and provides a stable friction-reducing effect.

[0040] The rotating shaft 320 is provided with an annular groove 400, and the snap-fit ​​member 310 is rotatably connected to the annular groove 400;

[0041] The temple 200 includes a first connecting part 210 and a second connecting part 220, and both the first connecting part 210 and the second connecting part 220 are provided with connecting holes 230;

[0042] When the snap-fit ​​310 is inserted into the connection hole 230, the connection hole 230 and the annular groove 400 are aligned.

[0043] The first connecting portion 210 and the second connecting portion 220 together form a U-shaped body.

[0044] The snap-fit ​​310, through its rotatable connection with the annular groove 400, ensures an effective connection between the frame connector 100 and the temple 200, and allows the temple 200 to rotate flexibly on the rotating shaft 320. Simultaneously, the first connecting portion 210 and the second connecting portion 220 of the temple 200, by having connecting holes 230 and engaging with the annular groove 400 via the snap-fit ​​310, make the connection more secure. In this embodiment, the rotating shaft 320 is provided with an annular groove 400, and the snap-fit ​​310 and the annular groove 400 form a reliable connection through rotatable connection. The snap-fit ​​310 is inserted into the connecting hole 230 of the temple 200 and engages with the annular groove 400. The frame and temple 200 can rotate via the rotating shaft 320, providing flexible unfolding and folding functions. The alignment of the connecting hole 230 with the annular groove 400 and the insertion of the snap-fit ​​310 provide stability to the connection, preventing loosening or instability between the temple 200 and the rotating shaft 320. The first connecting part 210 and the second connecting part 220 of the temple 200 together form a U-shape, further enhancing the stability and strength of the connection. The U-shaped design improves pressure resistance and disperses external pressure, making the connection of the temple 200 more robust and able to withstand greater external forces, thus extending its service life.
