[0004] To achieve the above objectives, the solution of this utility model is as follows: a windproof structure for eyeglasses, the eyeglasses having an eyeglass frame and a pair of temples, the pair of temples being pivotally connected to the rear ends of the left and right sides of the eyeglass frame, and also including two protective leaves, the two protective leaves being detachably installed on the left and right sides of the eyeglasses respectively, the protective leaves including a protective leaf body and a snap-fit ​​part, the snap-fit ​​part being used to snap and fix with the eyeglasses, so that after the protective leaf is snapped and fixed with the eyeglasses, the protective leaf body is located on the outer periphery of the eyeglasses facing the human body, and is used to block wind from blowing into the eyes from the outer periphery of the eyeglasses.

[0005] Furthermore, the snap-fit ​​part protrudes from the main body of the lens protector, and the eyeglasses are provided with a snap-fit ​​groove, into which the snap-fit ​​part can be inserted to snap and fix with the eyeglasses.

[0006] Furthermore, the snap-fit ​​part expands to form a protrusion at the end opposite to the main body of the lens, and the snap-fit ​​groove protrudes from the side wall of the eyeglass and extends back and forth so that it can slide back and forth after the snap-fit ​​part is inserted into the snap-fit ​​groove. A limit block is provided at the front end of the snap-fit ​​groove, and the limit block limits the protrusion to the side facing the main body of the lens so that when the snap-fit ​​part slides to the front end of the snap-fit ​​groove, it can prevent the protrusion from sliding out from the front end of the snap-fit ​​groove toward the main body of the lens.

[0007] Furthermore, the eyeglasses frame has temple connecting parts extending backward on both the left and right sides, with the temples pivotally connected to the temple connecting parts and locking grooves formed in the temple connecting parts.

[0008] Furthermore, a pivot groove is formed at the rear end of the temple connection part, and the front end of the temple is pivotally connected in the pivot groove. A snap-fit ​​groove is formed by extending forward from the pivot groove so that after the snap-fit ​​part is inserted into the snap-fit ​​groove, it can slide from back to front and snap-fit ​​and fix with the snap-fit ​​groove.

Therefore, it should not be construed as limiting the specific protection scope of this utility model.

[0030] like Figure 1-8As shown, this utility model provides a windproof structure for eyeglasses. The eyeglasses 1 have an eyeglass frame 2 and a pair of temples 3, which are pivotally connected to the rear ends of the left and right sides of the eyeglass frame 2. It also includes two protective leaves 4, which are detachably installed on the left and right sides of the eyeglasses 1. Specifically, the two protective leaves 4 are arranged in a mirror image. The protective leaves 4 can be installed on the inner side of the eyeglasses 1, on the side facing the face, or on the outer side of the eyeglasses 1, on the side away from the face; there are no specific limitations. The protective leaves 4 include a main body 41 and a locking part 42, which is used to engage with the eyeglasses 1. The glasses 1 are snapped in place so that after the protective leaf 4 is snapped in place with the glasses 1, the protective leaf body 41 is located on the outer periphery of the glasses 1 facing the human body, which is used to block the wind from blowing into the eyes from the outer periphery of the glasses 1. There are various snapping methods, such as the snapping of the protrusion and the snapping of the slot, or the snapping of the spring and the snapping of the hole, etc., without specific limitations. When the two protective leaves 4 are installed on the left and right sides of the glasses 1 respectively, they can achieve the windproof function, which is convenient for use in sports environments such as cycling. After the protective leaves 4 are removed from the glasses 1, the glasses 1 can meet the daily wearing needs without causing inconvenience to daily wear, so that the glasses 1 can be used in multiple scenarios.

[0031] In this specific embodiment, the snap-fit ​​part 42 protrudes from the lens protector body 41, and the glasses 1 is provided with a snap-fit ​​groove 5. The snap-fit ​​part 42 can be inserted into the snap-fit ​​groove 5 to snap and fix it to the glasses 1. The snap-fit ​​groove 5 can be provided on the outside of the glasses 1 or on the inside of the glasses 1. Correspondingly, when the snap-fit ​​groove 5 is provided on the outside of the glasses 1, the snap-fit ​​part 42 is located on the side of the lens protector body 41 facing the human body and snaps and fixes itself to the snap-fit ​​groove 5; when the snap-fit ​​groove 5 is provided on the inside of the glasses 1, the snap-fit ​​part 42 is located on the side of the lens protector body 41 away from the human face and snaps and fixes itself to the snap-fit ​​groove 5.

[0032] In this specific embodiment, the end of the snap-fit ​​portion 42 facing away from the lens protector body 41 is enlarged to form a protrusion 43. The snap-fit ​​groove 5 is exposed on the side wall of the glasses 1 and extends back and forth so that after the snap-fit ​​portion 42 is inserted into the snap-fit ​​groove 5, it can slide back and forth. A limiting block 6 is provided at the front end of the snap-fit ​​groove 5. The limiting block 6 limits the protrusion 43 on the side facing the lens protector body 41 so that when the snap-fit ​​portion 42 slides to the front end of the snap-fit ​​groove 5, it can prevent the protrusion 43 from sliding out from the front end of the snap-fit ​​groove 5 toward the lens protector body 41. Figure 6As shown, specifically, the snap-fit ​​part 42 also includes a connecting rod 49, which connects the protrusion 43 and the leaf protector body 41. The connecting rod 49 and the protrusion 43 combine to form a T-shaped structure. The outer contour dimension of the protrusion 43 is larger than the outer contour dimension of the connecting rod 49. There are two limiting blocks 6, which are respectively set at the upper and lower parts of the front end of the snap-fit ​​groove 5, so that the inner contour of the front end of the snap-fit ​​groove 5 is consistent with the outer contour of the snap-fit ​​part 42. When the snap-fit ​​part 42 is located at the front end of the snap-fit ​​groove 5, the limiting blocks 6 can protrude from the protrusion. The slide path of block 43 towards the main body 41 of the lens protector is designed to prevent the protrusion 43 from sliding directly out of the front end of the snap-fit ​​groove 5. When installing the lens protector 4, insert the connecting part 42 of the lens protector 4 into the rear end of the snap-fit ​​groove 5, and then slide it forward to the front end of the snap-fit ​​groove 5 to snap and fix it, so that the lens protector 4 is connected and fixed to the glasses 1. When removing the lens protector 4, slide the lens protector 4 to the rear end of the snap-fit ​​groove 5, and the snap-fit ​​part 42 can be pulled out directly from the snap-fit ​​groove 5 to separate the lens protector 4 from the glasses 1. The disassembly and assembly are simple and convenient. Furthermore, the lens protector 4 is integrally formed.

[0033] Key points combined Figure 1-4 As shown, the eyeglass frame 2 has temple connecting portions 21 extending rearward on both the left and right sides. The eyeglass frame 2 also includes a front portion 23 for mounting the lens 24. The temple 3 is pivotally connected to the temple connecting portion 21. A locking groove 5 is formed in the temple connecting portion 21. A pivot groove 22 is formed at the rear end of the temple connecting portion 21. The front end of the temple 3 is pivotally connected in the pivot groove 22. The temple 3 and the pivot groove 22 are pivotally connected by a pivot shaft. This is prior art and will not be described in detail. In order to simplify the overall structure of the eyeglass 1 without adding or changing it, the locking groove 5 is formed by extending forward from the pivot groove 22 so that after the locking portion 42 is inserted into the locking groove 5, it can slide from back to front and lock and fix with the locking groove 5.

[0034] To ensure a more secure connection between the leaf protector 4 and the eyeglasses 1, focus on the following aspects: Figure 5-6As shown, an elastic locking protrusion 7 is provided on the side wall of the locking groove 5. The elastic locking protrusion 7 can elastically extend and retract. After the locking part 42 is inserted into the locking groove 5, the elastic locking protrusion 7 is located on the front and rear sliding path of the locking part 42. A groove 44 is provided on the outer side wall of the locking part 42 to cooperate with the elastic locking protrusion 7, so that when the locking part 42 slides forward, the elastic locking protrusion 7 can slide into the groove 44 to limit the locking part 42 from sliding backward. The elastic locking protrusion 7 can be any existing elastically extendable element, with an elastic extension part and a cooperating part. The elastic extension part can be a spring or a spring sheet, etc. A sliding groove (not shown in the figure) is provided on the side wall of the locking groove 5, and the elastic extension part is extended and retracted in the sliding groove of the locking groove 5. Inside the groove, the mating part is fixed to the end of the elastic telescopic part away from the sliding groove. The mating part can extend and retract with the elastic telescopic part to extend out of the sliding groove or retract into the sliding groove. This is prior art and will not be described in detail. When worn, the lens 4 and the glasses 1 are firmly connected and the lens 4 will not slide back and forth. The elastic locking protrusion 7 can be set on the side wall or top wall of the locking groove 5, and the groove 44 can be set on the protrusion 43 or the connecting rod 49. There are no specific restrictions. When disassembly is required, simply press the elastic locking protrusion 7 against the sliding lens 4 to make the elastic locking protrusion 7 elastically retract and slide out of the groove 44. The elastic locking protrusion 7 separates from the groove 44, and the locking part 42 can slide backward and exit the locking groove 5.

[0035] Key points combined Figure 1 and Figure 6 As shown, the main body 41 of the eyeglasses has an upper baffle 45 and a side baffle 46. When the glasses 1 are worn on the eyes, the upper baffle 45 is located on the top side of the glasses 1 and extends laterally to cover the hollow area between the upper left and right sides of the glasses frame 2 and the face. The side baffle 46 is located between the lower edge of the temple 3 and the side edge of the glasses frame 2 to cover the hollow area between the back left and right sides of the glasses frame 2 and the face. When riding, this prevents wind from blowing into the eyes from above or from the cheekbones on both sides of the face.

[0036] In this specific embodiment, the lens protector 4 is installed on the side of the eyeglass frame 2 facing the human face, that is, on the inside of the eyeglasses 1. After the lens protector 4 is removed, it does not affect the overall appearance of the eyeglasses 1. When the lens protector 4 is not needed, it maintains the overall appearance of the eyeglasses 1, making it suitable for daily wear without creating an obtrusive feeling; (Focusing on...) Figure 7 As shown, a clearance area 47 is formed between the upper baffle 45 and the side baffle 46 so that when the temple 3 pivots and folds relative to the frame 2, the clearance area 47 can avoid the pivoting of the temple 3.

[0037] Key points combined Figure 8As shown, in order to ensure breathability during riding, the rear end of the leaf guard 4 has a ventilation hole 48. The number of ventilation holes 48 can be one, two or more. In this specific embodiment, the number of ventilation holes 48 is two. The rear end of the side baffle 46 of the leaf guard 4 forms a wavy curved surface. The curved surface is located on the side of the side baffle 46 away from the human face. The ventilation hole 48 is strip-shaped and formed on the curved surface. The wavy curved surface can guide the airflow, improve the airflow, and reduce the noise generated when the airflow is running.

[0038] The above description is only a preferred embodiment of this utility model and is not a limitation on the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
