Description

Technical Field

[0001] This utility model specifically relates to a sunglasses with a quick-change lens structure, belonging to the field of sunglasses technology. Background Technology

[0002] Sunglasses, also known as sunglasses or visors, are a type of eyewear specifically designed to protect the eyes from harmful ultraviolet rays and strong light from the sun. They reduce the intensity of light through the lenses, and can reduce eye fatigue, especially in outdoor environments with strong sunlight, such as at the beach, in the snow, or while driving.

[0003] Most sunglasses currently use a snap-fit ​​structure between the frame and the lens, secured with screws. When replacing the lens, special tools are required for disassembly. However, the screws are small and easily lost or stripped during disassembly, making the replacement process quite troublesome. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a sunglasses with a quick-change lens structure; it includes a frame and temples, the temples being hinged to both ends of the frame, a limiting frame being fixed inside the frame, a lens being placed on the limiting frame, a guide frame being installed on one side of the frame, a sliding groove being provided inside the guide frame, a slider being slidably connected inside the sliding groove, a first spring being provided between the sliding groove and the slider, a connecting frame being fixed to one end of the slider, a holding frame being hinged to one end of the connecting frame, a locking plate being fixed to the end of the holding frame away from the connecting frame, a insertion groove being provided inside the locking plate, and a locking component being provided inside one end of the frame.

[0005] The locking assembly includes a lock groove and a guide block. The lock groove is formed inside the frame and the shape inside the lock groove is the same as the shape outside the lock plate. The guide block is slidably disposed inside the frame. A pin is fixedly provided at one end of the guide block. A second spring is provided between one end of the guide block and the inside of the frame. A pull plate is installed on one side of the guide block.

[0006] Mounting brackets are fixedly installed at both ends of the frame, and a reinforcing rod is fixedly installed between the two sets of mounting brackets. A rotating rod is fixedly connected to one end of the mounting bracket, and a worm gear is installed at the other end of the rotating rod.

[0007] A protective shell is installed at one end of the temple. Inside the protective shell, a worm gear that meshes with a worm wheel is rotatably mounted. One end of the worm gear passes through the inside of the protective shell and is equipped with a lever.

[0008] The area where the limiting frame contacts the lens is provided with a rubber pad, and the area where the pressing frame contacts the lens is also provided with a rubber pad.

[0009] The surface of the pull plate is provided with protective texture and guide arrows.

[0010] Beneficial effects: Pulling the pull plate compresses the second spring, causing the pin to disengage from the locking plate and releasing the holding frame lock. Pushing the slider and rotating the holding frame releases the lens, completing the replacement. Then, rotating the holding frame to make it flush with the lens frame and releasing it allows the locking plate to be quickly placed into the insertion slot. After releasing the pull plate, the second spring resets to lock the lens. Installation and disassembly require no tools and avoid the risk of loss caused by disassembly using screws.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-6As shown, a pair of sunglasses with a quick-change lens structure includes a frame 1 and temples 20. The temples 20 are hinged to both ends of the frame 1. A limiting frame 2 is fixed inside the frame 1, and a lens 3 is placed on the limiting frame 2. A guide frame 4 is installed on one side of the frame 1. A groove 5 is opened inside the guide frame 4, and a slider 6 is slidably connected inside the groove 5. A first spring 7 is provided between the groove 5 and the slider 6. A connecting frame 8 is fixed to one end of the slider 6, and a holding frame 9 is hinged to one end of the connecting frame 8. The holding frame 9 is away from the connecting frame. One end of the frame 8 is fixedly provided with a locking plate 10, and the locking plate 10 has an insertion groove inside. The frame 1 is also provided with a locking component inside one end. The locking component includes a locking groove 11 and a guide block 12. The locking groove 11 is opened inside the frame 1, and the internal shape of the locking groove 11 is consistent with the external shape of the locking plate 10. The guide block 12 is slidably disposed inside the frame 1. One end of the guide block 12 is fixedly provided with a pin 13. A second spring 14 is provided between one end of the guide block 12 and the inside of the frame 1. A pull plate 15 is installed on one side of the guide block 12.

[0015] Working steps: When replacing lens 3, by pulling the pull plate 15, the guide block 12 slides and compresses the second spring 14, and the pin 13 exits from the insertion slot of the locking plate 10, releasing the locking state of the holding frame 9. Then, push the slider 6 to slide in the slide groove 5, driving the connecting frame 8 and the holding frame 9 to move, so that the holding frame 9 moves away from the lens 3, releasing the holding of the lens 3. At this time, one end of the holding frame 9 can rotate around the connecting frame 8, providing operating space for replacing and taking out the lens 3. Then, take out the old lens 3, put the new lens 3 into the limiting frame 2, and then release the slider 6. At this time, the first spring 7 pushes the slider 6 to reset, driving the connecting frame 8 and the holding frame 9 back to the initial position. During this process, rotate and adjust the holding frame 9 so that the holding frame 9 re-holds the new lens 3. Then, release the pull plate 15. At this time, the second spring 14 pushes the guide block 12 to reset, and the pin 13 re-inserts into the insertion slot of the locking plate 10, completing the locking of the holding frame 9 and completing the replacement operation of lens 3.

[0016] Furthermore, mounting brackets 16 are fixedly installed at both ends of the frame 1, and a reinforcing rod 17 is fixedly installed between the two sets of mounting brackets 16. A rotating rod 18 is fixedly connected to one end of the mounting bracket 16, and a worm gear 19 is installed at the other end of the rotating rod 18. A protective shell 21 is installed at one end of the temple 20. A worm 22 that meshes with the worm gear 19 is rotatably installed inside the protective shell 21. A lever is installed at one end of the worm 22 that passes through the inside of the protective shell 21. During operation, the reinforcing rod 17 is used to enhance the stability and strength of the frame 1 structure. By moving the lever, the worm 22 can be rotated, which in turn meshes with and drives the worm gear 19 to rotate, causing the rotating rod 18 and the mounting bracket 16 to rotate, thereby causing the entire frame 1 to rotate. This achieves the effect of adjusting the overall angle of the frame 1 and the lens 3, allowing the user to adjust the optimal wearing angle as needed. It should be noted that there is only one set of worm gear 19 and worm 22 mechanism in this device. In the illustration, the protective shell 21 is set with two sets for symmetry, making the sunglasses more visually balanced and harmonious.

[0017] Furthermore, a rubber pad is provided in the area where the limiting frame 2 contacts the lens 3, and a rubber pad is also provided in the area where the holding frame 9 contacts the lens 3. During operation, the rubber pad provides a uniform pressure distribution and increases the friction in the area where it contacts the lens 3.

[0018] Furthermore, the surface of the pull plate 15 is provided with protective texture and guide arrows. The protective texture increases friction with the hand, while the guide arrows make the operation process more intuitive.
