Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to eyeglasses with a windproof structure. Background Technology

[0002] When wearing glasses outdoors in windy conditions, wind can enter through the temples on both sides of the frame, blowing directly into the eyes and affecting comfort. Patent number "A Glasses with Windproof Sheets" discloses glasses with windproof sheets. These sheets have sheaths on the temples on both sides of the frame, with insert blocks on the sheaths inserting upwards into slots. The limiting blocks of these insert blocks hook into limiting notches for fixation. The sheaths prevent wind from blowing directly into the eyes from the sides of the glasses, improving comfort in windy weather. However, the connection method of the sheaths in existing technology is relatively simple, with poor fixation, and they are prone to loosening due to vibrations during walking or running, or external contact. Therefore, designing glasses with a windproof structure that improves the stability of the sheath connection and prevents it from loosening has become an urgent technical problem to be solved. Summary of the Invention

[0003] To solve the above problems, this utility model provides a pair of glasses with a windproof structure.

[0004] The present invention provides a pair of glasses with a windproof structure, comprising a frame, temples, and a plastic windproof component. The frame has pins on both sides that are hinged to the temples, and the inner side of the pins has a snap-fit ​​groove. The plastic windproof component includes a support plate that is attached to the top surface of the frame and side plates that are connected to both ends of the bottom surface of the support plate. The side plates have positioning grooves for the pins to snap into, and the side walls of the positioning grooves have snap-fit ​​blocks that cooperate with the snap-fit ​​grooves. The upper inner wall of the snap-fit ​​grooves has downwardly protruding pressing blocks, and the front edge of the support plate has a hook plate that extends to the front of the frame.

[0005] With the above structure, the first fixation is achieved by inserting the stake head into the positioning groove on the side baffle, which then holds the stake head from the inside towards the outside of the glasses. The second fixation is achieved by attaching a support plate to the top surface of the frame and having a hook plate extending to the front of the frame to hook the top edge of the frame. The third fixation is achieved by inserting a locking block from the positioning groove into a tenon-and-mortise joint. During the insertion of the locking block into the joint, the pressing block on the inner wall of the joint presses against the top surface of the locking block, causing elastic deformation and generating significant friction, further strengthening the third fixation and preventing the locking block from falling out of the joint. This achieves multiple fixations from the stake head and the top edge of the frame, improving the connection stability of the plastic windshield. The pressing block generates significant friction, preventing vibrations during walking or running from causing the locking block to fall out of the joint.

[0006] As a further improvement of this utility model, the extrusion block is a strip-shaped block parallel to the opening of the snap-fit ​​groove. The bottom surface of the extrusion block is provided with a downwardly protruding arc surface, and the edge of the snap-fit ​​block is provided with a guide slope that cooperates with the arc surface.

[0007] With the above structure, when the card block is inserted into the card slot, the guide slope extrudes the arc surface to guide it, causing the top surface of the card block to deform downwards, and the extrusion block and the arc surface can move the top surface of the card block more easily.

[0008] As a further improvement of this utility model, the top surface of the card block is provided with a groove that engages with the arc surface.

[0009] With the above structure, the top surface of the card block is provided with a groove that engages with the arc surface. When the card block is fully inserted into the groove, the arc surface is engaged in the groove, preventing the card block from leaving the groove. The pressing block remains outside the groove, maintaining pressure on the top surface of the card block, so that the arc surface and the card block always have a certain friction.

[0010] As a further improvement of this utility model, any extrusion block has no less than two arc surfaces, and the arc surfaces are continuously arranged to form a wave surface, with the shape of the groove corresponding to the wave surface.

[0011] With the above structure, a wave-like surface is formed by the continuous arrangement of multiple arc surfaces. When the plastic windshield is subjected to a small external force, part of the arc surface will come out of the groove, while the rest of the arc surface will remain in the groove, thus preventing the locking block from completely detaching from the locking groove.

[0012] As a further improvement of this utility model, the front edge of the side panel is fitted with the left and right side edges of the frame.

[0013] With the above structure, the front edge of the side panel fits into the left and right sides of the frame, reducing the gap between the side panel and the frame and improving the windproof effect. Attached Figure Description

[0019] like Figures 1-4 The image shows a pair of glasses with a windproof structure, including a frame 1, temples 2, and a plastic windproof component 3. The left and right sides of the frame 1 are provided with pins 4 that are hinged to the temples 2. The inner side of the pins 4 is provided with a snap-fit ​​groove 5. The plastic windproof component 3 includes a support plate 6 that is attached to the top surface of the frame 1 and side baffles 7 that are connected to both ends of the bottom surface of the support plate 6. The side baffles 7 are provided with positioning grooves 8 for the pins 4 to snap into. The side wall of the positioning groove 8 is provided with a snap-fit ​​block 9 that cooperates with the snap-fit ​​groove 5. The upper inner wall of the snap-fit ​​groove 5 is provided with a downwardly protruding pressing block 10. The front edge of the support plate 6 is provided with a hook plate 11 that extends to the front of the frame 1.

[0020] The first fixation is achieved by inserting the stake 4 into the positioning groove 8 on the side baffle 7, which then holds the stake 4 from the inside towards the outside of the glasses. The second fixation is achieved by attaching the support plate 6 to the top surface of the frame 1 and having a hook plate 11 extending to the front of the frame 1 to hook the top edge of the frame 1. The third fixation is achieved by inserting the locking block 9 on the positioning groove 8 into the locking groove 5 for mortise and tenon connection. During the insertion of the locking block 9 into the locking groove 5, the pressing block 10 on the inner wall of the locking groove 5 presses against the top surface of the locking block 9, causing the top surface of the locking block 9 to elastically deform and generate a large frictional force, further strengthening the third fixation and preventing the locking block 9 from falling out of the locking groove 5. This achieves multiple fixations from the stake 4 and the top edge of the frame 1, improving the connection stability of the plastic windshield 3. The pressing block 10 presses down on the locking block 9 to generate a large frictional force, preventing the locking block 9 from falling out of the locking groove 5 due to vibrations during walking or running.

[0021] The extrusion block 10 is a strip-shaped block parallel to the opening of the snap-fit ​​groove 5. The bottom surface of the extrusion block 10 is provided with a downwardly protruding arc surface 12, and the edge of the snap-fit ​​block 9 is provided with a guide slope 13 that cooperates with the arc surface 12.

[0022] When the card block 9 is inserted into the card slot 5, the guide slope 13 presses the arc surface 12 to guide it, causing the top surface of the card block 9 to be concave and deformed downwards, so that the pressing block 10 and the arc surface 12 can move the top surface of the card block 9 more easily.

[0023] The top surface of the card block 9 is provided with a groove 14 that engages with the arc surface 12.

[0024] The top surface of the card block 9 is provided with a groove 14 that engages with the arc surface 12. When the card block 9 is fully inserted into the engagement groove 5, the arc surface 12 is engaged in the groove 14, preventing the card block 9 from leaving the engagement groove 5. The pressing block 10 remains outside the groove 14, maintaining pressure on the top surface of the card block 9, so that the arc surface 12 and the card block 9 always have a certain friction.

[0025] The number of arc surfaces 12 of any extrusion block 10 is not less than two, and the arc surfaces 12 are arranged continuously to form a wave surface. The shape of the groove 14 corresponds to the wave surface.

[0026] By continuously arranging multiple arc surfaces 12 to form a wave surface, when the plastic windshield 3 is subjected to a small external force, some of the arc surfaces 12 will come out of the groove 14, while the remaining arc surfaces 12 will remain in the groove 14, thus preventing the locking block 9 from completely detaching from the locking groove 5.

[0027] The front edge of the side panel 7 is fitted with the left and right side edges of the frame 1.

[0028] By fitting the front edge of the side baffle 7 with the left and right sides of the frame 1, the gap between the side baffle 7 and the frame 1 is reduced, thus improving the windproof effect.
