Abstract
Description
Technical Field
[0001] This utility model specifically relates to a thin-film eyeglass with a straight-folding function, belonging to the field of eyeglasses technology. Background Technology
[0002] Eyeglasses are optical devices used to correct vision or protect the eyes. They typically consist of lenses and frames, with lenses custom-made to meet individual vision needs and help improve vision problems such as nearsightedness, farsightedness, and astigmatism.
[0003] Most folding glasses currently available use a damping hinge design at the connection between the nose pads and the frame to achieve folding and storage of the frame. At the same time, the temples are also equipped with a damping hinge structure in the middle to support folding in the middle. Through the double folding mechanism, the overall size of the glasses is significantly reduced, making them easy to carry and store.
[0004] However, after prolonged use, the damping hinge structure of the frame and temples is prone to mechanical fatigue and loosening due to frequent folding. This leads to a decrease in the stability of the connection between the temples and the frame, which in turn causes the entire frame to loosen, affecting wearing comfort and optical correction. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a thin-film eyeglass with a straight-folding function. It includes a nose pad, with rotating blocks rotatably connected to both ends of the nose pad via damping shafts. One end of each rotating block is connected to a frame. A first pressing and limiting component is provided inside the nose pad, and second pressing and limiting components are provided at both ends of the frame. The first pressing and limiting component includes a U-shaped frame, which is fixedly disposed inside the nose pad. A sliding rod slides through the U-shaped frame, with a T-shaped push block fixedly connected to one end of the sliding rod inside the U-shaped frame, and a triangular slider fixedly connected to the other end of the sliding rod. A first spring is provided between the triangular slider and the U-shaped frame.
[0006] The first pressing and limiting component also includes a support frame, which is fixedly installed inside the nose pad. Limiting plates are fixedly installed at both ends of the support frame. Trapezoidal slide plates are also slidably connected to both ends of the support frame. The inclined surfaces of the two sets of trapezoidal slide plates and the triangular slider cooperate with each other. One end of the trapezoidal slide plate is connected to an insert rod, which is slidably connected to the nose pad. A second spring is provided between the trapezoidal slide plate and the inner wall of the nose pad.
[0007] The first pressing limit component also includes two sets of slots, both of which are opened on the surface of the rotating block and are set at a 90-degree angle.
[0008] The second pressing and limiting component includes a first temple, which is rotatably disposed at one end of the frame. A second temple is slidably connected inside the first temple, and multiple sets of slots are provided on one side of the inner wall of the first temple.
[0009] The second pressing and limiting component also includes a support block, which is fixedly disposed inside the second temple. One end of the support block is rotatably connected to a rocker plate. One end of the rocker plate extends to the end of the second temple near the first temple and is connected to a locking block. The other end of the rocker plate extends to the end of the second temple away from the first temple and is connected to a pressure plate. A third spring is provided between the end of the rocker plate near the pressure plate and the second temple.
[0010] The surface of the T-shaped push block is provided with anti-slip texture.
[0011] Beneficial effects: By pushing the T-shaped push block to move the slide bar and triangular slider, the trapezoidal slide plate can be quickly released from its constraint on the insert rod and retracted into the nose pad, allowing the frame to fold freely. After releasing the push block, the first spring returns to its original position and pushes the triangular slider to press the trapezoidal slide plate, causing the insert rod to re-insert into the rotating block slot and complete the locking. This solves the problem of loose connection caused by mechanical fatigue in traditional damping pivots, and improves the folding stability and long-term reliability of the frame.
[0012] By pressing the pressure plate to drive the rocker to rotate, the locking block can be disengaged from the slot, allowing the second temple to slide freely inside the first temple. After releasing the pressure plate, the third spring resets and pushes the locking block back into the slot to complete the locking. The multi-slot design supports quick adjustment of the temple length and adopts a lever-type buckle structure to avoid loosening caused by mechanical fatigue of traditional damping shafts.

[0015] 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.
[0016] Please see Figures 1-4 As shown, a thin-film type of glasses with a straight-folding function includes a nose pad 1. Both ends of the nose pad 1 are rotatably connected to rotating blocks 2 via damping pivots 4. One end of each rotating block 2 is connected to a frame 3. A first pressing and limiting assembly is provided inside the nose pad 1. Second pressing and limiting assemblies are provided at both ends of the frame 3. The first pressing and limiting assembly includes a U-shaped frame 5, which is fixedly installed inside the nose pad 1. A sliding rod 6 slides through the U-shaped frame 5. A T-shaped push block 7 is fixedly connected to one end of the sliding rod 6 inside the U-shaped frame 5, and a triangular slider 8 is fixedly connected to the other end of the sliding rod 6. A first spring 9 is provided between the triangular slider 8 and the U-shaped frame 5. The first pressing and limiting assembly also includes a support frame 1. 0. The support frame 10 is fixedly installed inside the nose pad 1. Limiting plates 11 are fixedly installed at both ends of the support frame 10. Trapezoidal slide plates 12 are also slidably connected to both ends of the support frame 10. The inclined surfaces of the two sets of trapezoidal slide plates 12 and the triangular slider 8 cooperate with each other. One end of the trapezoidal slide plate 12 is connected to the insertion rod 13. The insertion rod 13 and the nose pad 1 are slidably connected through each other. A second spring 14 is provided between the trapezoidal slide plate 12 and the inner wall of the nose pad 1. The first pressing and limiting component also includes two sets of slots 15. Both sets of slots 15 are opened on the surface of the rotating block 2, and the two sets of slots 15 are set at a 90-degree angle. The elastic thrust of the first spring 9 is much greater than the elastic thrust of the second spring 14.
[0017] Operating steps: When the user needs to fold the glasses, by pushing the T-shaped push block 7, the slide bar 6 and the triangular slider 8 are moved away from the support frame 10. At this time, the triangular slider 8 no longer presses against the inclined surfaces of the two sets of trapezoidal slide plates 12. Under the restoring elasticity of the second spring 14, the two sets of trapezoidal slide plates 12 are pushed to slide closer to the center area of the support frame 10, and simultaneously the insertion rod 13 is disengaged from the corresponding slot 15 and retracted into the nose pad 1, releasing the lock on the rotating block 2. At this time, the user can freely fold the glasses. Frame 3, after folding the two sets of frame 3 together, release the T-shaped push block 7. Under the restoring elasticity of the first spring 9, push the triangular slider 8 to move quickly towards the support frame 10. Its two sides of the inclined surface contact and squeeze the inclined surfaces of the two sets of trapezoidal slide plates 12, overcome the elasticity of the second spring 14 and push the two sets of trapezoidal slide plates 12 to slide away from the center area of the support frame 10 until they contact the limiting plate 11. During this process, push the insert rod 13 from the inside of the nose pad 1 into the corresponding slot 15 to quickly lock the rotating block 2.
[0018] Furthermore, the second pressing and limiting assembly includes a first temple 16, which is rotatably disposed at one end of the frame 3. A second temple 23 is slidably connected inside the first temple 16. Multiple sets of slots 17 are provided on one side of the inner wall of the first temple 16. The second pressing and limiting assembly also includes a support block 18, which is fixedly disposed inside the second temple 23. One end of the support block 18 is rotatably connected to a rocker arm 19. One end of the rocker arm 19 extends to the end of the second temple 23 near the first temple 16 and is connected to a locking block 20. The other end of the rocker arm 19 extends to the end of the second temple 23 away from the first temple 16 and is connected to a pressure plate 22. A third spring 21 is provided between the end of the rocker arm 19 near the pressure plate 22 and the second temple 23.
[0019] Working steps: When the glasses need to be stored, press the pressure plate 22, which in turn pushes the rocker arm 19 to rotate around the support block 18. At this time, the rotation of the rocker arm 19 causes the locking block 20 to disengage from the slot 17. During this process, the third spring 21 is compressed and stores reset energy. After the locking block 20 disengages, the second temple 23 can slide freely inside the first temple 16. Push the second temple 23 to the end inside the first temple 16 and release the pressure plate 22. At this time, the reset force of the third spring 21 pushes the rocker arm 19 to rotate in the opposite direction, causing the locking block 20 to re-insert into the corresponding slot 17 to lock the new position of the second temple 23 and prevent the second temple 23 from sliding freely inside the first temple 16. The multiple slots 17 allow users to quickly adjust the overall length of the temples by inserting the locking block 20 into different slots 17 to adapt to different wearing needs.
[0020] Furthermore, the surface of the T-shaped push block 7 is provided with anti-slip texture, which can increase the friction between the surface of the T-shaped push block 7 and the user's hand, thereby improving the stability when pushing the T-shaped push block 7.
