[0002] Swimming goggles are a common piece of equipment used in swimming. They are worn tightly around the swimmer's eyes so that the swimmer can open their eyes to observe the surrounding environment while preventing water from entering the eyes and causing eye diseases.

[0003] Currently, common swimming goggles consist of two frames, a nose bridge connecting the two frames, and an elastic band connecting the two frames. A lens is integrally molded onto the frame, forming a cavity within the lens and frame to accommodate the swimmer's blinking. An anti-light coating is applied to the outer surface of the lens to reduce light transmission and prevent strong external light from entering the goggles and causing discomfort to the swimmer's eyes. Because the frame and lens are a single unit, it's impossible to change the lens to suit different lighting conditions. Therefore, swimmers must carry multiple goggles with different anti-light coatings, and the lenses are generally plano lenses. If a swimmer is nearsighted, the entire goggles need to be replaced, failing to meet the needs of different swimmers. Utility Model Content

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These descriptions are intended to aid in understanding the utility model but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] Example 1

[0031] See Figures 1 to 6 This embodiment relates to a combined myopia swimming goggles, including two frames 1, a nose bridge 2 connecting the two frames 1, an elastic band 3 connected to the side of the two frames 1 away from the nose bridge 2, and lenses and pads 4 disposed on the frames 1. When worn, the two frames 1 are fastened to the swimmer's face by the elastic band 3, and the pads 4 are in close contact with the swimmer's face to form a sealed cavity at the eyes, preventing water from entering the interior of the frames 1, and allowing the swimmer to open their eyes underwater and observe the surrounding environment through the lenses on the frames 1.

[0032] Specifically, the frame 1 has a U-shaped frame structure. The frame 1 has a first slot 5 on its inner side and an insertion port on its top side that connects to the first slot 5. A closable cap 6 is provided at the insertion port. The lens is inserted into the first slot 5 from the insertion port, and the cap 6 is closed to fix the lens. The lens after being inserted into the first slot 5 and the frame 1 form a cover cavity inside, so as to cover the swimmer's eyes when wearing the glasses and allow the swimmer to blink in the cover cavity.

[0033] The pressure cap 6 has a second slot 7 on its inner side. When the pressure cap 6 is closed, the top side of the lens is fitted into the second slot 7 on the pressure cap 6. At this time, the bottom side of the lens abuts against the bottom wall of the bottom groove of the first slot 5, the left and right sides of the lens abut against the bottom walls of the opposite sides of the first slot 5, and the top side of the lens abuts against the bottom wall of the top groove of the second slot 7, so as to form a fixing force on the outer periphery of the lens to complete the lens fixing.

[0034] The pressure cap 6 is hinged to the insertion port on the frame 1 on one side of the length direction via a hinge. The pressure cap 6 can rotate around the hinge side on the other side of the length direction and lock with the other side of the insertion port on the frame 1. The pressure cap 6 and the insertion port on the frame 1 are provided with a locking structure on the locking side to lock the pressure cap 6 after it is closed. The locking structure locks the pressure cap 6 after it is closed, so that the insertion port on the frame 1 is not easy to be opened after the pressure cap 6 is closed, thus preventing the lens inserted on the frame 1 from falling off due to the insertion port being opened.

[0035] The sockets on the cover 6 and the frame 1 are respectively provided with locking surfaces on the locking side for them to fit together when closed; the locking structure includes a screw 8 provided on the locking surface of the frame 1, and a locking hole 9 opened on the locking surface of the cover 6. The locking hole 9 penetrates the top surface of the cover 6 so that the screw 8 can pass through the locking hole 9 and be threadedly connected to the nut 10 to complete the locking when the cover 6 is closed.

[0036] In this embodiment, the lock hole 9 is a U-shaped hole. The opening side of the lock hole 9 is connected to the side of the locking side of the pressure cover 6 so that when the pressure cover 6 is closed, the stud can be inserted and engaged with the lock hole 9 from the side of the pressure cover 6.

[0037] The first slot 5 and the second slot 7 are provided with elastic gaskets (not shown in the figure) on the side wall of the slot. The elastic gaskets are used to seal the gap between the lens and the first slot 5 and the second slot 7, thereby improving the waterproofness.

[0038] The lens has a main body and edge portions formed around the main body. The edge portions on opposite sides and the bottom side of the lens mate with the first slot 5, and the edge portion on the top side of the lens mates with the second slot 7. When worn, the main body of the lens is opposite to the swimmer's eyes.

[0039] In this embodiment, two sets of lenses are provided. Each set of lenses includes a water-blocking lens 11 and a refractive lens 12. The water-blocking lens 11 and the refractive lens 12 are arranged sequentially from far to near along the axial direction of the eye. The water-blocking lens 11 is used to prevent water from entering the interior of the goggle frame 1, and the refractive lens 12 is used to correct the refractive error of the swimmer's eyes so that nearsighted swimmers can clearly observe the underwater environment. Accordingly, each goggle frame 1 is provided with two first slots 5, and each pressure cap 6 is provided with two second slots 7. This allows the water-blocking lens 11 and the refractive lens 12 to be inserted respectively, and a cavity is formed between the inserted water-blocking lens 11 and the refractive lens 12 to reduce heat transfer between the inside and outside of the goggles, thereby improving the anti-fog effect.

[0040] The outer surface of the water-blocking lens 11 is coated with a light-reducing coating (not shown in the figure) to reduce the intensity of light entering the swimming goggles, reduce irritation to the swimmer's eyes, and improve comfort.

[0041] The frame 1 has a connecting ear 13 on the side away from the nose bridge 2. One end of the elastic band 3 is connected to the connecting ear 13 on one of the frames 1, and the other end of the elastic band 3 is connected to the connecting ear 13 on the other frame 1. When worn, the elastic band 3 can be used to tighten the swimming goggles around the swimmer's eyes.

[0042] The frame 1 and the cover 6 have a flange 14 on the side away from the water-blocking lens 11. When the cover 6 is closed, the flange 14 on the frame 1 and the cover 6 are joined together to form a ring. The pad 4 has an annular groove 15 on its inner side. The flange 14 and the annular groove 15 cooperate with each other to fix the pad 4 on the frame 1.

[0043] In this embodiment, two first slots 5 are provided inside the frame 1 to allow the insertion of the water-blocking lens 11 and the refractive lens 12. The lenses are locked by closing the pressure cap 6. Each pressure cap 6 has two second slots 7 on its inner side. The two first slots 5 and the two second slots 7 respectively cooperate with the edges of the water-blocking lens 11 and the refractive lens 12 to fix the water-blocking lens 11 and the refractive lens 12. This makes the swimming goggles a detachable assembly structure. Swimmers can replace the water-blocking lens 11 with different colored light-reducing coatings and the refractive lens 12 with a color corresponding to the swimmer's myopia according to their actual needs, thus meeting the needs of different swimmers.

[0044] Example 2

[0045] See Figures 7 to 10The difference between this second embodiment and the first embodiment lies in that the second embodiment has two lenses, which are respectively inserted into two frames 1. Each frame 1 has a corresponding first slot 5, and each cover 6 has a second slot 7. The outer surface of each lens is a water-blocking surface and is coated with a light-reducing coating (not shown in the figure). The water-blocking surface of the lens prevents water from entering the interior of the frame 1 and weakens the intensity of light transmitted into the swimming goggles, reducing the stimulation to the swimmer's eyes and improving comfort. Each lens has an inwardly concave refractive surface on its inner surface. The refractive surface of the lens corrects the swimmer's refractive error, so that nearsighted swimmers can clearly observe the underwater environment. The degree of concavity of the refractive surface corresponds to the swimmer's degree of nearsightedness. The lens has a hollow cavity inside, which reduces heat transfer between the inside and outside of the swimming goggles, thereby improving the anti-fog effect.

[0046] In this embodiment, a lens with a water-blocking surface and a refractive surface, and a hollow cavity is inserted into each frame. Each frame only needs one lens to block external water and correct the swimmer's refractive error. Correspondingly, each frame only needs to be provided with a first slot 5 and the cover only needs to be provided with a second slot 7 to fix the lens. This can significantly reduce the thickness of the swimming goggles, thereby reducing water resistance and wearing weight during swimming and improving the swimmer's user experience.

[0047] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
