Description

Technical Field

[0001] This utility model relates to the technical field of eyeglasses, specifically to a quick-change lens structure and eyeglasses using this quick-change lens structure. Background Technology

[0002] Eyeglasses are a combination of lenses and frames, used to improve vision, protect the eyes, or for decorative purposes. Depending on their purpose, eyeglasses are categorized into corrective lenses, safety goggles, swimming goggles, sunglasses, and sports glasses, among others. For those who value aesthetics, eyeglasses not only improve vision and protect the eyes but also serve a decorative purpose. Different occasions and outfits require different accessories, including decorative eyeglasses, specifically in terms of the shape, color, and material of the lenses and / or frames. For instance, the same frame can be paired with lenses of different shapes and colors to create different decorative effects. Similarly, the same pair of glasses can be fitted with lenses of different shades to suit indoor or outdoor use, day or night. However, once manufactured, eyeglasses typically have the frames and lenses fixed together, making disassembly difficult for non-professionals. In other words, existing eyeglass lenses are often not replaceable. If multiple decorative effects are desired, multiple pairs of glasses must be made, which is extremely expensive and impractical for most people. In view of this, the inventor has specifically researched and developed a quick-change lens structure and eyeglasses using this quick-change lens structure, so that users can easily and quickly change the lenses on the frame as needed to meet their usage needs, and this invention arises from this. Utility Model Content

[0003] The purpose of this invention is to provide a quick-change lens structure and a pair of glasses using this quick-change structure, so that users can easily change the lenses, the replacement operation is simple, and the replaced lenses are firmly and stably installed.

[0004] To achieve the above objectives, the solution of this utility model is:

[0005] A quick-change lens structure is disclosed, wherein the lens adopts a one-piece left and right lens structure; a clip is installed in the middle of the one-piece lens corresponding to the bridge of the nose; a hook is formed on the back of the clip and a hook groove is formed on the top edge of the frame's central bridge; the clip is installed on the frame's central bridge by means of the hook hooking into the hook groove; a first magnetic element is also installed on the back of the clip, and a second magnetic element is installed on the frame's central bridge; the clip is fixed to the frame's central bridge by means of the magnetic attraction between the first and second magnetic elements, thereby realizing the assembly of the lens and the frame.

[0006] A protruding locking block is formed on the upper front of the locking component, a locking bracket is formed on the lower front of the locking component, and a locking hole is formed on the lens. The lower edge of the lens is lifted by the engagement of the protruding locking block and the locking hole, so that the locking component is fixedly installed on the lens.

[0007] The connection between the convex block and the clip is reduced in size to form an elastic root. The convex block and the elastic root are inserted together into the clip hole, so that the front top of the clip is fixedly installed with the lens.

[0008] The connection between the card holder and the card piece forms a recessed groove, and the lower edge of the lens forms a convex edge. The convex edge is embedded in the recessed groove, so that the lower front of the card piece is fixedly installed together with the lower edge of the lens.

[0009] The card is H-shaped, and a first magnetic element is mounted on the back of the card below the H-shape.

[0010] The central beam of the eyeglass frame extends downward to form a clip mounting part, and a recessed groove is formed on the clip mounting part. The second magnetic element is installed on the clip mounting part, and the clip is precisely embedded in the recessed groove when it is fixed at the central beam of the eyeglass frame.

[0011] The lower end of the mounting part of the frame forks to form a nose pad mounting part, and the nose pads are assembled on the nose pad mounting part.

[0012] A pair of glasses consists of lenses and a frame. The lenses are assembled onto the frame using the aforementioned quick-change lens structure. The lenses are of a single, integrated design. A clip is installed in the middle of the integrated lens corresponding to the bridge of the nose. A hook is formed on the back of the clip, and a groove is formed on the top edge of the frame's central bridge. The clip is installed on the central bridge of the frame by hooking the clip into the groove. A first magnetic element is also installed on the back of the clip, and a second magnetic element is installed on the central bridge of the frame. The clip is fixed to the central bridge of the frame by the magnetic attraction between the first and second magnetic elements, thus assembling the lenses and the frame.

[0013] By adopting the above solution, this utility model fixes the lens and the clip together, and assembles the lens and frame together by assembling the clip with the frame. Because the clip is assembled with the frame by hooking into a groove, and its positioning with the frame is achieved by magnetic attraction between magnetic components, the assembly operation is quick, accurate, secure, and stable. For disassembly, simply push the clip upwards; this misaligns the magnetic components, weakening the magnetic attraction, and disengages the hook from the groove, allowing the clip to be quickly removed from the frame, thus separating the lens from the frame. The disassembly operation is simple, quick, and convenient.

[0014] In this way, when using this utility model, different lenses with different functions and colors can be easily and quickly changed according to different scenarios, clothing and styling needs. For example, dark lenses can be used when cycling during the day, and transparent lenses can be changed at night, which is very convenient to use. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] It should be noted that the terms front, back, inside, outside, top, bottom, left, right, first, second, third, etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the technical features indicated, unless otherwise explicitly defined.

[0029] like Figures 1 to 7 As shown, this utility model discloses a quick-change lens structure, which is suitable for quick assembly and replacement between lens 1 and frame 2.

[0030] The lens 1 adopts a one-piece structure. A clip 3 is installed in the middle of this one-piece lens 1 corresponding to the bridge of the nose. A hook 31 is formed on the back of the clip 3, pointing backwards. Correspondingly, a hook groove 21 is formed on the top edge of the bridge of the frame 2. By hooking the hook 31 into the hook groove 31, the clip 3 can be installed on the bridge of the frame 2. A first magnetic element 32 is also installed on the back of the clip 3. Correspondingly, a second magnetic element 22 is installed on the bridge of the frame 2. The magnetic attraction between the first and second magnetic elements allows the clip 3 to be quickly aligned and fixed to the bridge of the frame 2. The first and second magnetic elements 32 can both be magnets, or one can be a magnet and the other a metal part that can be attracted by a magnet, or other elements with magnetic attraction, which will not be listed here. Thus, this invention, by using the clip 3 fixed to the lens 1, utilizes the hook structure and magnetic attraction to achieve rapid assembly and replacement of the lens 1 and the frame 2.

[0031] Furthermore, the optimized design of this utility model is that the central beam of the frame 2 extends downward to form a clip mounting portion 24, and a recessed groove 23 is formed on the clip mounting portion 24. The second magnetic element 22 is installed on the clip mounting portion 24. When the clip 3 is fixed to the central beam of the frame 2 by the hook structure and magnetic adsorption, the clip 3 is precisely embedded in the recessed groove 23. In this way, by means of the cooperation between the recessed groove 23 and the outer contour of the clip 3, the deflection of the clip 3 on the frame 2 can be prevented, further making the assembly between the lens 1 and the frame 2 more secure and stable. In this utility model, the mounting portion of the frame 2 branches at the lower end to form a nose pad mounting portion 25, and the nose pad 26 is assembled on the nose pad mounting portion 25 for easy replacement.

[0032] Furthermore, the optimized design of this utility model is that the clip 3 is H-shaped, which not only saves material but also reduces weight. A first magnetic element 32 is installed on the back of the clip 3 below the H-shape. In this way, by means of the magnetic attraction between the first magnetic element 32 and the second magnetic element 22, the lower part of the clip 3 is fixed to the center beam of the frame 2, while the upper part of the clip 3 is fixed to the center beam of the frame 2 by means of the hook 31. This one-up-one-down fixing method is more stable.

[0033] To facilitate assembly and replacement for consumers and make operation more convenient, this utility model typically uses the clip 3 as a standard accessory fixed to the lens 1, thus avoiding wear and tear caused by repeated disassembly and reassembly of the clip 3 and lens 1. To make the assembly of the clip 3 and lens 1 more secure and stable, this utility model further forms a protruding clip 33 on the upper front of the clip 3 and a clip holder 34 on the lower front of the clip 3. Correspondingly, a clip hole 11 is formed on the lens 1. The protruding clip 34 of the clip 3 engages with the clip hole 11, and the clip holder 34 lifts the lower edge of the lens 1, thus firmly fixing the clip 3 onto the lens 1 as a single unit. Furthermore, this utility model also forms a recessed groove 35 at the connection between the clip holder 34 and the clip 3, and a protruding edge 12 on the lower edge of the lens 1. When the clip 3 and lens 1 are assembled together, the protruding edge 12 fits precisely into the recessed groove 35, making the position of the lower front of the clip 3 and the lower edge of the lens 1 more accurate when fixed together. Furthermore, to facilitate the assembly of the clip 3, the size of the connection between the convex clip 33 and the clip 3 is reduced to form an elastic root 36. The convex clip 33 and the elastic root 36 are inserted together into the clip hole 11, so that the front top of the clip 3 is fixedly installed with the lens 1. The elastic root 36 gives the convex clip 33 a certain elasticity during assembly and allows it to be adjusted naturally, which not only facilitates assembly but also makes the assembly more secure.

[0034] This utility model also discloses a pair of eyeglasses using the aforementioned quick-change lens structure, comprising a lens 1 and a frame 2. The lens 1 is assembled onto the frame 2 using the aforementioned quick-change lens structure, enabling quick assembly and replacement. As mentioned above, the lens 1 adopts a one-piece left and right structure; a clip 3 is installed in the middle of the one-piece lens 1 corresponding to the bridge of the nose; a hook 31 is formed on the back of the clip 3, and a hook groove 21 is formed on the top edge of the bridge of the frame 2. The clip 3 is installed on the bridge of the frame 2 by hooking the hook 31 into the hook groove 21; a first magnetic element 32 is also installed on the back of the clip 3, and a second magnetic element 22 is installed on the bridge of the frame 2. By means of the magnetic attraction between the first magnetic element 32 and the second magnetic element 22, the clip 3 is automatically aligned and fixed on the bridge of the frame 2, thereby realizing the assembly of the lens 1 and the frame 2.

[0035] This invention allows for the initial fixing of the lens 1 to the clip 3, followed by the assembly of the clip 3 with the frame 2. During assembly, the magnetic attraction between the first magnetic element 32 and the second magnetic element 22 causes the clip 3 to automatically align with the center beam of the frame 2 and engage. The hook 31 of the clip 3 then hooks into the hook groove 21, assembling the clip 3 with the frame 2. This achieves the assembly and positioning of the lens 1 and the frame 2, resulting in a fast, accurate, secure, and stable assembly operation. For disassembly, a slight force is applied to push the clip 3 upwards. This causes misalignment between the first magnetic element 32 and the second magnetic element 22, weakening the magnetic attraction, and disengages the hook 31 from the hook groove 21. This allows for the quick removal of the clip 3 along with the lens 1 from the frame 2, separating the lens 1 from the frame 2. The disassembly operation is simple, fast, and convenient.

[0036] The above description is merely an example of the implementation of this utility model and is not intended to limit the scope of protection of this utility model. It should be noted that any equivalent changes made by those skilled in the art after reading this specification, based on the design concept of this case, shall fall within the scope of protection of this case.
