Description

Technical Field

[0001] The invention relates to a glass swimming goggle. Background Art

[0002] The swimming goggles in the prior art are composed of a main lens and a side lens. The plane of the main lens is the same as that of myopic glasses, labor protection goggles, wind goggles, and diving goggles. Its plane is parallel to the plane of the face (or the plane of the eyes). This is also the inertial thinking of the lens designer. The designer believes that only a parallel design between the two can not affect the viewing effect of the eyes. Generally speaking, the side lenses of swimming goggles are not as clear as the main lenses. Their main function is to form a slope at the two corners to reduce the resistance of water, and secondly, to act as a cover to prevent water leakage. For flat glass lenses, it is impossible to set up side lenses to transition to the two ends of the swimming goggles. In theory, the absence of side lenses will reduce the visual angle. If the main lens parallel to the face is used alone, it will cause the two ends to bulge outward at right angles and cannot transition to the two ends. This not only increases the volume, but most importantly, this structure will increase the resistance of water and affect the appearance of the swimming goggles. Summary of the invention

[0003] The invention aims to provide a swimming goggles with a main lens tilt angle, so as to minimize the resistance of the flat glass swimming goggles in water, expand the field of vision on both sides and improve the appearance effect.

[0004] The technical solution of the present invention is that a glass groove 6 is provided at the front end of the silicone eye ring 2 of the glass swimming goggles, the two silicone eye rings 2 are connected by a nose bridge 4, the headband 1 is connected to the silicone eye ring 2, and the glass lens 3 is embedded in the glass groove 6 with elastic potential energy. The front ends of the two silicone eye rings 2 are respectively provided with glass grooves 6 tilted backward at corresponding angles, and then the outer edge 7, the inner edge 8, the lens 3, and the boss 5 related to the glass groove 6 are tilted backward at the same angle; it can also be simply said that the glass lens 3 is tilted backward at a corresponding angle.

[0005] It is an embodiment that the inner diameter of the outer edge 7 of the glass groove 6 is smaller than the inner diameter of the inner edge 8 .

[0006] The closed surface of the outer edge 7 of the glass groove 6 is inclined inward at a certain angle, so that the glass groove 6 is approximately triangular, which is an embodiment.

[0007] The upper and lower ends of the middle positions behind the two bosses 8 are respectively inclined at a certain angle to extend two headbands 1 to both ends as starting points. The two extended headbands 1 can form double headbands 1 respectively, or can be combined together to form one headband 1 after extending.

[0008] The technical effect of the present invention is that the two lenses of the glass swimming goggles are tilted towards both ends to expand the field of vision. This structure can incorporate the functions of the side lenses of ordinary swimming goggles into the main lenses, eliminating the side lenses of ordinary swimming goggles, and relatively expanding the field of vision on both sides within the limited main lenses. It is a technical measure to save costs and reduce volume. The windshields of cars are all tilted, and this tilt angle is quite large, which does not affect the driver's forward vision, while the tilt angle of the swimming lens is limited, which can be almost ignored relative to the slope of the car windshield; secondly, the two main lenses of the glass swimming goggles are tilted towards both ends to form an approximate streamline shape, avoiding the right angles protruding at both ends of the flat glass swimming goggles to increase the resistance of the swimming goggles in the water; thirdly, the volume of the swimming goggles is relatively reduced, and the appearance effect is improved.

[0012] See attached Figure 1 The glass swimming goggles are provided with only one main lens, namely the lens 3. For the convenience of description, the glass groove 6 at the front end of the silicone eye ring 2 is used as a reference. The glass groove 6 is composed of a groove formed between the inner closed surface of the outer edge 7 and the inner closed surface of the inner edge 8. The outer surface of the outer edge 7 and part of the outer surface of the inner edge 8 (another part of the outer surface of the inner edge 8 is connected to the rear end of the eye ring 2) and the outer surface of the bottom of the groove form a convex outer surface called a boss 5, or a convex outer shape formed by the boss 5 wrapping the glass groove 6.

[0013] The size of the glass groove 6 is smaller than the edge size of the glass lens 3 , so when the glass lens 3 is inserted into the glass groove 6 , an interference fit connection is generated. At this time, the elastic silicone glass groove 6 forms elastic potential energy to wrap, fix and seal the glass lens 3 .

[0014] When the lens 3 is subjected to water pressure, the closed surface of the inner edge 8 of the glass groove 6 will be pressed tighter by the lens 3, so the sealing is more reliable and safe.

[0015] The two silicone eye rings 2 are respectively provided with glass grooves 6 tilted backward at corresponding angles, and the outer edge 7, inner edge 8, lens 3 and boss 5 closely related to the glass groove 6 are tilted at the same angle. That is, the front planes of the two silicone eye rings 2 are tilted backward at corresponding angles as a whole, which can also be referred to as the lens 3 tilting backward at corresponding angles.

[0016] The contact surface between the rear end of the silicone eye ring 2 and the face is provided with an elastic and comfortable sealing surface; the inner diameter of the outer edge 7 of the glass groove 6 is smaller than the inner diameter of the inner edge 8 of the glass groove 6, or it can be said that the closed surface length of the outer edge 7 (glass groove height) is greater than the closed surface length of the inner edge 8. The lens 3 is installed from the rear end of the eye ring 2, and is installed into the glass groove 6 by expanding the inner diameter of the inner edge 8 of the glass groove 6. After entering, the lens 3 is tightly wrapped by the glass groove 6 with elastic potential energy, and the outer edge 7 (relatively high glass groove) with a relatively small inner diameter is provided in front, which can effectively prevent the lens 3 with a relatively large outer diameter from slipping out, and ensure the reliability of its fixed sealing.

[0017] The closed surface of the outer edge 7 of the glass groove 6 is inclined inward at a certain angle, so that the inner closed surface of the outer edge 7 is not parallel to the inner closed surface of the inner edge 8, that is, the groove section of the glass groove 6 is approximately triangular. This structure can make the outer edge 7 in the air always have an elastic force to keep a close fit with the lens 3 (in the vicinity). Figure 1 The inner closed surface of the outer edge 7 is parallel to the inner closed surface of the inner edge 8, which is a tight fit effect during use). In order to make this force stronger, one or two raised rings are added to the outer surface of the outer edge 7 to increase the thickness of the silicone to ensure that sufficient elastic force is formed at the inner diameter edge to press the lens 3, which is also another measure to prevent the lens 3 from falling out.

[0018] The main parts of the two ends of the nose bridge 4 are connected to the rear end surface of the boss 5, which can prevent the outer edge 7 of the glass groove 6 from being pulled and deformed, and prevent the lens 3 from falling out. The ends of the headband 1 are connected from the upper and lower points of the middle position behind the boss 5 of the outer shape of the glass groove 6 as starting points, and are connected to the two ends of the eye ring 2 at a corresponding angle to tilt backward. The purpose is to make the headband 1 apply tension from the center position of the eye ring 2. First, it is to ensure that the boss 5 wrapping the lens 3 will not be deformed and affect the fixation of the lens 3; second, the tension of the headband 1 starting from the upper and lower points in the middle will make the eye ring 2 evenly stressed and comfortable to wear.

[0019] The two headbands 1 extending from the upper and lower points of the middle position can form a double headband 1 respectively, and then be connected by an adjustment buckle; or they can be combined together at both ends of the eye ring 2 to form a headband 1 and then connected by an adjustment buckle.
