Description

Technical Field

[0001] This invention relates to the field of eyeglass frame technology, and specifically to a screwless quick-release eyeglass frame. Background Technology

[0002] To improve the comfort and fit of eyeglasses, existing technologies have incorporated air-cushioned nose pads. These flexible air bladders create a smooth contact with the bridge of the nose, reducing localized pressure and improving slip resistance. Some existing nose pads use a one-piece, interconnected air bladder design for even pressure distribution; others employ independent dual-air bladder structures to accommodate different fit requirements. Meanwhile, technologies such as micro-rotating inflation structures and modular quick-release connections are also being applied in small inflatable products and eyeglass accessories.

[0003] However, existing airbag nose pads generally suffer from limited functionality and insufficient adaptability. They often only offer one mode of integrated pressure equalization or independent support, making it difficult to flexibly switch according to the wearer's nose bridge shape and usage needs. Existing inflation adjustment methods are not convenient to operate, and nose pads are mostly fixed to the frame, making them difficult to disassemble and replace individually, resulting in high maintenance costs. Overall, existing technologies have failed to effectively combine multi-airbag support, manual adjustment, and modular structure, making it difficult to simultaneously consider wearability, ease of use, and cost-effective maintenance, thus failing to meet diverse wearing needs.

[0004] To address the aforementioned technical deficiencies, a solution is proposed. Summary of the Invention

[0005] This invention provides a screwless quick-release eyeglass frame, which solves the problem that existing airbag nose pads are not flexible enough due to their one-piece design.

[0006] To achieve multi-dimensional flexible adjustment, convenient disassembly and assembly, and comfortable wearing of the nose pads for eyeglasses, this invention achieves this through the following technical solution: A screwless quick-release eyeglass frame, comprising a frame body, on which a nose pad mechanism is provided. The number of nose pad mechanisms is two, symmetrically distributed left and right. Each nose pad mechanism includes a mounting block, which is fixedly connected to the frame body. A connecting rod is detachably connected to the mounting block. An adjustment knob is rotatably connected to the end of the connecting rod away from the mounting block. A mounting plate is rotatably connected to the adjustment knob. A rotating cylinder is rotatably connected to the side of the mounting plate near the connecting rod. A connecting cylinder is fixedly connected to the end of the rotating cylinder near the mounting plate, passing through and rotatably connected to the mounting plate. A conical cylinder is fixedly connected to the end of the connecting cylinder away from the mounting plate. An airbag is provided inside the conical cylinder through an adjustment mechanism. The adjustment mechanism is used to uniformly and disperse the inflation and deflation of the airbag and to adjust the position of the airbag.

[0007] Furthermore, openings are provided on both sides of the outer surface of the mounting block, and pressing membranes are fixedly connected in the openings. An installation cavity is provided between the two pressing membranes. The installation cavity is located inside the mounting block. A spring is movably connected in the installation cavity. A connecting piece is fixedly connected to the top of the spring. The connecting piece is movably connected to the mounting block. The top of the connecting piece is rotatably connected to the connecting rod.

[0008] Furthermore, the spring is V-shaped.

[0009] Furthermore, a ball groove is provided at the end of the connecting rod away from the mounting block, and a ball bearing is rolled in the ball groove. The ball bearing is fixedly connected to the adjustment knob.

[0010] Furthermore, the adjustment mechanism includes a spiral groove formed on the conical cylinder. A rotating pair is provided on the mounting plate. The mounting end of the rotating pair is fixedly connected to the mounting plate. A sliding rod is fixedly connected to the movable end of the rotating pair. A collar is sleeved on the sliding rod and slidably connected to it. A movable rod is fixedly connected to the collar via a telescopic rod. An inflation knob is rotatably connected to the movable rod. An abutment block is fixedly connected to the output end of the inflation knob. The end of the abutment block away from the inflation knob is fixedly connected to and communicates with the airbag.

[0011] Furthermore, a slider is fixedly connected to the end of the movable rod away from the adjustment knob. The slider is located in the spiral groove. A limit piece is provided at the end of the slider away from the movable rod. The limit piece is located on and in contact with the outer wall of the conical cylinder. A spring is fixedly connected between the limit piece and the slider.

[0012] Furthermore, the number of adjustment mechanisms is several, and the adjustment mechanisms are radially distributed with the center of the mounting plate as the center.

[0013] Furthermore, a rotating shaft is fixedly connected to the center of the mounting plate, the rotating shaft passes through the center of the mounting plate, and the rotating shaft is fixedly connected to the adjustment knob. A second friction wheel is fixedly connected to the end of the rotating shaft away from the mounting plate. A first friction wheel is rotatably connected to the slide rod. The first friction wheel is located on the slide rod at the end away from the rotating pair. A first gear is fixedly connected to the end of the first friction wheel away from the rotating pair. A second gear is fixedly connected to the inflation knob.

[0014] Furthermore, when the slider moves to the end of the spiral groove near the mounting plate, gear one meshes with gear two, and several friction wheels one contact friction wheels two.

[0015] The present invention has the following beneficial effects: This screwless, quick-release eyeglass frame utilizes a rotating cylinder, a spiral groove within a conical cylinder, and a slider for transmission. Rotating the cylinder synchronously drives multiple airbags to perform linear telescopic movements, precisely adjusting the relative distance between the airbags and the frame to flexibly adjust support height and spacing. Simultaneously, the limiting constraints of the sliding rod, collar, and telescopic rod effectively prevent radial offset during airbag extension and retraction, ensuring consistent synchronous movement of the multiple airbags. It can accommodate different nose bridge heights and widths. The linear telescopic movement of the airbags achieves intermittent meshing of the transmission gears; when an airbag moves to the meshing position near the mounting plate, gear one and gear two mesh. With the adjustment knob turned, multiple airbags can be inflated and deflated simultaneously, making operation efficient and convenient. When an airbag moves out of the engagement range, the corresponding inflation knob can be turned individually to inflate and deflate a single airbag independently. This perfectly adapts to wearing scenarios with asymmetrical nose bridges and different support pressure requirements on the left and right sides. At the same time, the V-shaped spring clips provide a stable limit between the nose pad module and the frame. When disassembling, simply press the pressing film to squeeze the spring clip upwards to unlock it. The nose pad module can be quickly disassembled and installed without any auxiliary tools, facilitating daily cleaning, replacement of worn parts, and maintenance of the nose pads, significantly reducing usage and maintenance costs.

[0020] Please see Figures 1-10 This invention provides a technical solution: a screwless quick-release eyeglass frame, including a frame body 1, on which a nose pad mechanism is provided. The number of nose pad mechanisms is two and they are symmetrically distributed from left to right. The nose pad mechanism includes a mounting block 2, which is fixedly connected to the frame body 1. A connecting rod 5 is detachably connected to the mounting block 2. An adjustment knob 9 is rotatably connected to the end of the connecting rod 5 away from the mounting block 2. A mounting piece 10 is rotatably connected to the adjustment knob 9. A rotating cylinder 11 is rotatably connected to the side of the mounting piece 10 near the connecting rod 5. A connecting cylinder 12 is fixedly connected to the end of the rotating cylinder 11 near the mounting piece 10. The connecting cylinder 12 passes through the mounting piece 10 and is rotatably connected to it. A conical cylinder 13 is fixedly connected to the end of the connecting cylinder 12 away from the mounting piece 10. An airbag 25 is provided inside the conical cylinder 13 through an adjustment mechanism. The adjustment mechanism is used to unify and disperse the inflation and deflation of the airbag 25 and to adjust the position of the airbag 25.

[0021] The frame 1 is the overall frame except for the nose pads of the eyeglass frame. The frame 1 serves as the overall supporting base. The nose pad mechanism is fixedly mounted on the frame 1 with symmetrical left and right sides. The nose pad mechanism is fixed to the frame 1 by the mounting block 2. The mounting block 2 has a mounting cavity 7 inside. The mounting cavity 7 is equipped with a V-shaped spring piece 6. Pressing membranes 3 are fixed at the openings on both sides of the mounting block 2. The top of the spring piece 6 is connected to the connecting piece 4. The connecting piece 4 is rotatably connected to the connecting rod 5.

[0022] Both sides of the outer surface of the mounting block 2 have openings, and a pressing membrane 3 is fixedly connected inside the opening. An installation cavity 7 is opened between the two pressing membranes 3. The installation cavity 7 is located inside the mounting block 2. A spring piece 6 is movably connected inside the installation cavity 7. A connecting piece 4 is fixedly connected to the top of the spring piece 6. The connecting piece 4 is movably connected to the mounting block 2. The top of the connecting piece 4 is rotatably connected to the connecting rod 5. The spring piece 6 is V-shaped.

[0023] The material of the pressing membrane 3 is silicone rubber.

[0024] Under normal conditions, the spring piece 6 relies on its own elastic snap-fit ​​limit to make the connecting rod 5 and the mounting block 2 form a stable assembly. When disassembling, press the pressing films 3 on both sides. The pressing films 3 squeeze the spring piece 6 to deform and lift it up, releasing the snap-fit ​​limit. Then the connecting piece 4, connecting rod 5 and the entire nose pad mechanism can be removed from the mounting block 2. When installing, align the spring piece 6 into the mounting cavity 7. After releasing the pressing films 3, the spring piece 6 elastically resets and snaps back into place, realizing the quick disassembly and assembly of the nose pad mechanism without screws or tools.

[0025] The connecting rod 5 has a ball groove at the end away from the mounting block 2, and a ball bearing 8 is rolled in the ball groove. The ball bearing 8 is fixedly connected to the adjusting knob 9.

[0026] The end of the connecting rod 5 is in rolling engagement with the ball bearing 8 through a ball groove. The ball bearing 8 is fixedly connected to the adjusting knob 9, allowing the adjusting knob 9 to rotate flexibly relative to the connecting rod 5.

[0027] The adjustment mechanism includes a spiral groove 14, which is formed on the conical cylinder 13. A rotating pair 15 is provided on the mounting plate 10. The mounting end of the rotating pair 15 is fixedly connected to the mounting plate 10. A sliding rod 16 is fixedly connected to the movable end of the rotating pair 15. A collar 24 is sleeved on the sliding rod 16 and slidably connected. A movable rod 22 is fixedly connected to the collar 24 via a telescopic rod 23. An inflation knob 30 is rotatably connected to the movable rod 22. A contact block 29 is fixedly connected to the output end of the inflation knob 30. The end of the contact block 29 away from the inflation knob 30 is fixedly connected to and communicates with the airbag 25. A slider 21 is fixedly connected to the end of the movable rod 22 away from the adjustment knob 9. The slider 21 is located in the spiral groove 14. A limit piece 19 is provided at the end of the slider 21 away from the movable rod 22. The limit piece 19 is located on and in contact with the outer wall of the conical cylinder 13. A spring 20 is fixedly connected between the limit piece 19 and the slider 21.

[0028] The inflation knob 30 and the airbag 25 together form the existing micro rotary inflation and deflation airbag. The telescopic rod 23 is a physical telescopic rod, with its two ends fixedly connected to the movable rod 22 and the collar 24, respectively. The adjustment knob 9 is connected to the mounting plate 10. The mounting plate 10 is rotatably equipped with a rotating cylinder 11, a connecting cylinder 12 and a conical cylinder 13. The surface of the conical cylinder 13 is provided with a spiral groove 14. The mounting plate 10 is equipped with a sliding rod 16 through a rotating pair 15. The collar 24 is slidably sleeved on the sliding rod 16. The collar 24 is connected to the movable rod 22 through the telescopic rod 23. The end of the movable rod 22 is provided with a slider 21 adapted to the spiral groove 14. A limiting piece 19 is provided on the outside of the slider 21. A spring 20 is connected between the limiting piece 19 and the slider 21.

[0029] Rotating the rotating drum 11 can sequentially drive the connecting drum 12 and the conical drum 13 to rotate synchronously. The spiral groove 14 rotates with the conical drum 13 and drives the slider 21 to produce displacement. Under the limiting and guiding action of the sliding rod 16, the collar 24 and the telescopic rod 23, the movable rod 22 and the airbag 25 can only move in a straight line. The spring 20 keeps the slider 21 in contact with the spiral groove 14 and the limiting piece 19 in contact with the outer wall of the conical drum 13, ensuring that the displacement adjustment is stable and without any movement.

[0030] There are several adjustment mechanisms, which are radially distributed around the center of the mounting plate 10. A rotating shaft 27 is fixedly connected to the center of the mounting plate 10, and the rotating shaft 27 passes through the center of the mounting plate 10. The rotating shaft 27 is fixedly connected to the adjustment knob 9. A second friction wheel 28 is fixedly connected to the end of the rotating shaft 27 away from the mounting plate 10. A first friction wheel 17 is rotatably connected to the slide rod 16. The first friction wheel 17 is located on the slide rod 16 at the end away from the rotating pair 15. A first gear 18 is fixedly connected to the end of the first friction wheel 17 away from the rotating pair 15. A second gear 26 is fixedly connected to the inflation knob 30. When the slider 21 moves to the spiral groove 14 near the end of the mounting plate 10, the first gear 18 meshes with the second gear 26, and several first friction wheels 17 are in contact with the second friction wheel 28.

[0031] Friction wheel 17 and friction wheel 28 are made of rubber, and the contact block 29 is made of lightweight stainless steel alloy. The contact block 29 has a hollow structure. The center of the mounting plate 10 is fixed with a rotating shaft 27. The upper end of the rotating shaft 27 is fixed to the adjusting knob 9, and the lower end is equipped with friction wheel 28. Friction wheel 17 is rotatably mounted on the slide rod 16. The lower end of friction wheel 17 is fixedly connected to gear 18. The inflation knob 30 on the movable rod 22 is fixedly equipped with gear 26. The output end of the inflation knob 30 is connected to the contact block 29 and communicates with the airbag 25.

[0032] When the slider 21 moves with the spiral groove 14 to the side closer to the mounting plate 10, each friction wheel 17 simultaneously engages with the friction wheel 28, and the gear 18 meshes with the corresponding gear 26. At this time, rotating the adjustment knob 9 can drive the friction wheel 28 to rotate synchronously via the rotating shaft 27. Relying on friction transmission, all friction wheels 17 are driven to rotate in linkage. Then, through the meshing transmission of gear 18 and gear 26, each inflation knob 30 and the contact block 29 are driven to move synchronously, so that all airbags 25 are inflated and deflated uniformly. When the slider 21 moves to the side away from the mounting plate 10, the friction wheel 17 and friction wheel 28, and gear 18 and gear 26 are disengaged, and the transmission relationship is broken. A single inflation knob 30 can be rotated to independently control the inflation and deflation of the corresponding airbag 25.

[0033] Working principle: Under normal conditions, the spring piece 6 relies on its own elasticity to lock and limit the connection, so that the connecting rod 5 and the mounting block 2 form a stable assembly. When disassembling, press the pressing films 3 on both sides. The pressing films 3 squeeze the spring piece 6 to deform and lift it up, releasing the locking and limiting, so that the connecting piece 4, connecting rod 5 and the entire nose pad mechanism can be removed from the mounting block 2. When installing, align the spring piece 6 into the mounting cavity 7. After releasing the pressing films 3, the spring piece 6 elastically resets and re-locks, realizing the screwless and tool-free quick disassembly and assembly of the nose pad mechanism. The end of the connecting rod 5 is connected through... The ball groove and the ball bearing 8 roll together, and the ball bearing 8 is fixedly connected to the adjusting knob 9, allowing the adjusting knob 9 to rotate flexibly relative to the connecting rod 5. Rotating the rotating cylinder 11 can sequentially drive the connecting cylinder 12 and the conical cylinder 13 to rotate synchronously. The spiral groove 14 rotates with the conical cylinder 13 and drives the slider 21 to produce displacement. Under the limiting and guiding action of the sliding rod 16, the collar 24 and the telescopic rod 23, the movable rod 22 and the airbag 25 can only move in a straight line. The spring 20 keeps the slider 21 in contact with the spiral groove 14 and the limiting piece 19. The slider 21 fits snugly against the outer wall of the conical cylinder 13, ensuring smooth displacement adjustment without any shifting. When the slider 21 moves with the spiral groove 14 to the side close to the mounting plate 10, each friction wheel 17 simultaneously contacts the friction wheel 28, and gear 18 meshes with the corresponding gear 26. At this time, rotating the adjustment knob 9 will drive the friction wheel 28 to rotate synchronously via the rotating shaft 27. Relying on friction transmission, all friction wheels 17 are driven to rotate in unison, and then through the meshing transmission of gear 18 and gear 26, each inflation wheel is driven synchronously. The knob 30 and the contact block 29 are activated to inflate and deflate all airbags 25 in a unified manner. When the slider 21 moves to the side away from the mounting plate 10, the friction wheel 17 and friction wheel 28, and the gear 18 and gear 26 are disengaged, and the transmission relationship is broken. A single inflation knob 30 can be rotated to independently control the inflation and deflation of the corresponding airbag 25. This achieves multiple functions, including adjustable airbag support position, unified inflation and deflation of the whole airbag and independent inflation and deflation of a single airbag, and screwless quick-release of the nose pad module.
