[0042] Please refer to Figure 1 This utility model provides an adjustable diopter eyeglass, including a frame body 10, a slidable first lens 21, and a second lens 22. Both the first lens 21 and the second lens 22 have at least one free-form surface, and the free-form surfaces of the first lens 21 and the second lens 22 are arranged opposite to each other.
[0043] The frame body 10 is provided with a groove structure for guiding the sliding of the first lens 21. The first lens 21 is provided with a sliding limiting structure adapted to the groove structure. By sliding the sliding limiting structure in the groove structure, the horizontal position of the first lens 21 relative to the second lens 22 is changed, so that the relative position of the first lens 21 and the second lens 22 in the horizontal direction when worn by default moves, resulting in a change in the combined focusing ability, thereby achieving the purpose of vision correction.
[0044] Please refer to Figure 2 When the first lens 21 slides, it can move relative to the second lens 22, resulting in a change in the combined focusing ability, thereby achieving the purpose of vision correction.
[0045] By changing the position of the lenses to alter the path of light refraction, the refractive power can be adjusted, thus meeting the clear vision requirements of people with different vision needs in different scenarios without the need to switch between multiple pairs of glasses.
[0046] Please refer to the reference. Figures 4 to 6 In this embodiment, the frame body 10 includes a lens ring 11.
[0047] The sliding groove structure is a first sliding groove 12 disposed inside the lens ring 11, and the sliding limiting structure is a first sliding limiting part 212 disposed on the first lens 21. The position of the first sliding limiting part 212 corresponds to the position of the first sliding groove 12, and the first sliding limiting part 212 is slidably limited within the first sliding groove 12.
[0048] The first slide groove 12 provides a precise guide track for the sliding of the first lens 21. The first sliding limit part 212 is in close cooperation with the first slide groove 12 to ensure that the first lens 21 does not shift or shake during the sliding process, thus ensuring the accuracy and stability of the diopter adjustment and ensuring that the user can operate more smoothly when adjusting the diopter of the glasses.
[0049] In this embodiment, the mirror ring 11 is provided with a second sliding groove 14, and a sliding push button 13 is provided in the second sliding groove 14.
[0050] The push button 13 is provided with a drive limiting part 132, and the outer periphery of the first lens 21 is provided with a drive limiting groove 211. The drive limiting part 132 is limited within the drive limiting groove 211. When the push button 13 slides in the first slide groove 12, it drives the first lens 21 to slide relative to the lens ring 11.
[0051] By setting the push button 13 to achieve precise driving of the first lens 21, the user can easily adjust the position of the first lens 21 by simply pushing the push button 13, thereby changing the refractive power of the glasses.
[0052] In this embodiment, the drive limiting groove 211 is formed by the interval between two drive limiting protrusions 2111 arranged side by side.
[0053] Understandably, the cooperation between the drive limiting part 132 and the drive limiting groove 211 ensures the effectiveness and reliability of the push button 13 in driving the first lens 21, while the two drive limiting protrusions 2111 can stably limit the position of the drive limiting part 132 on the push button 13, preventing it from moving in an unexpected direction, thereby avoiding the situation where the lens detaches from the push button 13 or the drive fails during use, and improving the stability of the eyeglasses' diopter adjustment.
[0054] In this embodiment, the push button 13 is provided with a second sliding limit part 131, which is a hook-shaped structure and is slidably hooked on the inner side of the lens ring 11.
[0055] During the sliding process of the push button 13, the hook-shaped second sliding limit part 131 further restricts the position of the push button 13, preventing the push button 13 from tilting up or disengaging from the lens ring 11 in the direction perpendicular to the sliding direction, ensuring that the push button 13 always slides within the predetermined track, and enhancing the stability of the connection between the push button 13 and the lens ring 11.
[0056] Please refer to this again. Figures 1 to 4 and refer to together Figure 7 and Figure 8 Furthermore, in this embodiment, the diopter-adjustable eyeglasses also include a detachable second lens 22.
[0057] The second lens 22 is surrounded by an outer frame 222, and the outer frame 222 and the lens ring 11 are magnetically detachable.
[0058] In this embodiment, a first magnetic clasp 2221 is embedded inside the outer frame 222, and a second magnetic clasp is provided inside the lens ring 11 at the position for inserting the outer frame 222. After the outer frame 222 is inserted into the lens ring 11, the first magnetic clasp 2221 can be magnetically attracted and fixed to the second magnetic clasp, which facilitates the quick installation and removal of the second lens 22. Users can remove the second lens 22 according to actual needs to facilitate cleaning of dirty areas between the two lenses, thereby ensuring the clarity of the glasses.
[0059] Specifically, one of the first magnetic attractor 2221 and the second magnetic attractor is a magnet, and the other is an iron component (such as an iron block, patch, or iron frame) or a magnet. It should be noted that when both the first magnetic attractor 2221 and the second magnetic attractor are magnets, the polarities of the first magnetic attractor 2221 and the second magnetic attractor are opposite in order to provide magnetic attraction.
[0060] The lens rim 11 has a handle groove 111 at its bottom, and the outer frame 222 has a handle protrusion 2222 at its bottom that matches the handle groove 111. This mating structure between the handle protrusion 2222 and the handle groove 111 provides the user with a clear point of leverage, making it easier and more accurate for the user to connect or separate the outer frame 222 from the lens rim 11. This improves the convenience and efficiency of lens replacement and reduces the risk of damage to the lens or frame due to improper operation.
[0061] In this embodiment, the outer periphery of the second lens 22 is provided with a fixed limiting part 221, and the inner periphery of the outer frame 222 is provided with a fixed limiting groove 2223, and the fixed limiting part 221 is fixedly limited within the fixed limiting groove 2223.
[0062] The tight fit between the fixed limiting part 221 and the fixed limiting groove 2223 ensures that the second lens 22 is stably positioned within the outer frame 222, preventing the second lens 22 from shifting, shaking, or falling off during daily use, lens replacement, or when the glasses are subjected to external impact. This ensures the stability and reliability of the second lens 22 during use, thereby guaranteeing the vision correction effect and overall quality of the glasses.
[0063] Please refer to Figure 9 In this embodiment, the push button 13 is made by two-color injection molding, and the push button 13 is provided with a friction part 133 on the side near the lens ring 11. The friction part 133 is an elastic element with elasticity and friction force, which is used to form an interference fit between the push button 13 and the second slide groove 14. In addition to improving the user's feel when adjusting the diopter, it can also keep the push button 13 and the lens ring 11 relatively stationary when there is no external force, preventing the push button 13 from sliding on its own due to accidental slight vibration or shaking, which would cause unnecessary changes in the diopter of the glasses.
[0064] Therefore, only when the user applies sufficient external force can the push button 13 overcome the resistance of the friction part 133 to slide, thereby achieving precise adjustment of the refractive power, ensuring the stability of the refractive power of the glasses during wear, and improving the user's wearing experience and the accuracy of vision correction.
[0065] Furthermore, the outer surface of the push button 13 is flush with the outer surface of the lens rim 11, thereby ensuring that the outer surface of the eyeglasses is flat.
[0066] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
