Description

Technical Field

[0001] This utility model relates to the field of sports goggles, and in particular to replaceable frame sports goggles. Background Technology

[0002] Sports goggles are eye protection gear specifically designed for sports activities. Their core function is to protect the eyes from physical injuries (such as impacts and splashes), environmental disturbances (such as strong light, wind, sand, and ultraviolet radiation), or chemical irritants (such as sweat and liquid splashes) that may be encountered during sports. These goggles are typically made of high-strength, impact-resistant polycarbonate (PC) or special plastic materials. The frames are designed to fit the contours of the face and are equipped with non-slip nose pads and temples to ensure stability during vigorous activity. Lenses offer different features depending on the type of sport, such as UV protection (UV400 protection), anti-fog coating (reducing fogging caused by temperature differences), scratch-resistant treatment, or polarized technology (reducing glare). Some high-end products also feature interchangeable lenses to adapt to different lighting conditions. Sports goggles are widely used in skiing, cycling, basketball, swimming, and other sports, ensuring safety while enhancing athletic performance through clear vision and a comfortable wearing experience.

[0003] In existing technologies, most replaceable frame sports goggles are worn on the head using elastic straps. Over time, these straps lose elasticity due to material aging. Aged straps cannot provide sufficient tightening force, causing the goggles to become loosely secured to the head, affecting protective performance. Furthermore, frequent stretching and loosening accelerates fatigue of the elastic material, further leading to loss of elasticity. Because the straps are tightly integrated with the replaceable frame sports goggles, they are difficult to remove and replace independently. Although some goggles use special interfaces or fixing devices to connect the straps, these require specialized tools or techniques for disassembly and installation, making them difficult for ordinary users to operate. Therefore, when the elastic straps lose elasticity, become damaged, need to be replaced with straps of different elastic strengths, or need cleaning, the disassembly and use of the elastic straps becomes inconvenient, thus reducing the effectiveness of the replaceable frame sports goggles. Utility Model Content

[0004] The main purpose of this invention is to provide replaceable frame sports goggles, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] Replaceable frame sports goggles include a sports goggle body, a frame, and lenses. Several magnetically attracted blocks are fixedly connected to the opposite surfaces of the frame and the sports goggle body, and the sports goggle body and frame are magnetically attracted together by these blocks. Lenses are also fixedly installed inside the frame, and the frame is further fixed to the front end of the sports goggle body via buckles on both sides. A wearing mechanism is located at the rear of the sports goggle body, and the wearing mechanism includes an elastic strap and an L-shaped edge. The goggles consist of a plate, a knob, a movable plate, and a threaded short rod. The elastic restraint straps are respectively fitted onto the outside of the positioning plates on both sides of the main body of the sports goggles through positioning holes at both ends. L-shaped side plates are fixedly connected to the side walls of the main body of the sports goggles. The knob is movably connected to the vertical part of the L-shaped side plate through a rotating convex ring on the side wall. The movable plate is movably connected to the bottom surface of the horizontal part of the L-shaped side plate through a sliding block at the top. The limiting plate is fixedly connected to the inner side wall of the movable plate. The movable plate is also movably connected to the knob through a threaded short rod on the outer side wall.

[0007] Furthermore, positioning plates are fixedly installed on the left and right side walls of the main body of the sports goggles, and limit openings are provided on the side walls of the positioning plates.

[0008] Furthermore, the elastic restraint band has positioning openings at both ends, and positioning plates are inserted and installed in the positioning openings.

[0009] Furthermore, L-shaped side plates are fixedly installed on the left and right side walls of the main body of the sports goggles above the positioning plate, and a horizontal sliding opening is provided on the top surface of the horizontal part of the L-shaped side plate. A through hole is provided on the outer wall of the vertical part of the L-shaped side plate, and a rotating protrusion is provided on the vertical part of the L-shaped side plate outside the through hole.

[0010] Furthermore, a rotating convex ring is fixedly installed on the inner side wall of the knob, and the rotating convex ring is movably installed in the rotating convex groove. A threaded hole corresponding to the through hole is also opened on the side wall of the knob.

[0011] Furthermore, a sliding block is fixedly installed on the top surface of the movable plate, and the sliding block is movably installed in the sliding port. A limiting plate is fixedly installed on the inner side wall of the movable plate, and the limiting plate is inserted into the limiting port. A threaded short rod is fixedly installed on the outer side wall of the movable plate, and the threaded short rod passes through the through hole and is threadedly connected to the threaded hole.

[0012] Furthermore, the overall structure of the main body of the sports goggles is hollowed out.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, a lens-equipped frame can be quickly and securely attached to the sports goggles using a snap-on and magnetic method. This allows for easy frame replacement when the lens is damaged or when a plane or spherical lens is needed. Combined with the wearing mechanism, the user can quickly put on the sports goggles with the replaced frame using the elastic strap. When the elastic strap needs to be replaced, rotating the knob moves a threaded rod through the threaded hole, causing the rod to move outwards along the threaded hole. The threaded rod also drives a movable plate... The movable plate moves outward via the sliding block on the top surface until the limiting plate moves out of the limiting opening. Then, the elastic restraint strap can be removed from the positioning plate for replacement. This facilitates the disassembly and replacement of the elastic restraint strap, allowing for timely replacement when the elasticity is lost, the strap is damaged, or a strap with a different elastic strength is needed, or when cleaning is required. This ensures that the user can wear the replaceable frame sports goggles stably and securely through the wearing mechanism, thereby improving the effectiveness of the replaceable frame sports goggles.

[0022] like Figure 1 - Figure 5 As shown, replaceable frame-type sports goggles include a sports goggle body 1, a frame 2, and a lens 3. Several magnetically attracted blocks 6 are fixedly connected to the opposite surfaces of the frame 2 and the sports goggle body 1, and the sports goggle body 1 and the frame 2 are magnetically attracted to each other via the magnetically attracted blocks 6. The lens 3 is also fixedly installed inside the frame 2, and the frame 2 is also fixedly connected to the front end of the sports goggle body 1 via buckles 4 on both sides. A wearing mechanism 5 is provided at the rear of the sports goggle body 1, and the wearing mechanism 5 includes an elastic restraint strap 9, an L-shaped side plate 11, and a knob 15. The movable plate 18 and the threaded short rod 21, and the elastic restraint strap 9 are respectively fitted onto the outside of the positioning plates 7 on both sides of the sports goggle body 1 through the positioning ports 10 at both ends. L-shaped side plates 11 are fixedly connected to the side walls of the sports goggle body 1. The knob 15 is movably connected to the vertical part of the L-shaped side plate 11 through the rotating protrusion 16 on the side wall. The movable plate 18 is movably connected to the bottom surface of the horizontal part of the L-shaped side plate 11 through the sliding block 19 at the top. The limiting plate 20 is fixedly connected to the inner side wall of the movable plate 18. The movable plate 18 is also movably connected to the knob 15 through the threaded short rod 21 on the outer side wall.

[0023] like Figure 3 As shown, positioning plates 7 are fixedly installed on the left and right side walls of the sports goggle body 1, respectively. The positioning plates 7 are used to cooperate with the positioning port 10 to achieve positioning and installation of the elastic restraint strap 9. The side wall of the positioning plate 7 is provided with a limiting port 8, which is used to cooperate with the limiting plate 20 to achieve limiting and installation of the elastic restraint strap 9.

[0024] like Figure 4 As shown, the elastic restraint strap 9 has positioning holes 10 at both ends, and the positioning plate 7 is inserted into the positioning hole 10. After the positioning plate 7 is inserted into the positioning hole 10, the elastic restraint strap 9 can be positioned and connected with the replaceable frame sports goggles.

[0025] like Figure 5As shown, L-shaped side plates 11 are fixedly installed on the left and right side walls of the sports goggle body 1 above the positioning plate 7. The top surface of the horizontal part of the L-shaped side plate 11 is provided with a horizontal sliding opening 12. The sliding opening 12 is used to cooperate with the sliding block 19 to realize the sliding operation. The outer wall of the vertical part of the L-shaped side plate 11 is provided with a through hole 13. The through hole 13 can guide the movement of the threaded short rod 21. The vertical part of the L-shaped side plate 11 and outside the through hole 13 is also provided with a rotating protrusion 14. The rotating protrusion 14 is used to cooperate with the rotating protrusion ring 16 to restrict the movement of the knob 15 to realize positioning rotation.

[0026] like Figure 5 As shown, a rotating convex ring 16 is fixedly installed on the inner side wall of the knob 15, and the rotating convex ring 16 is movably installed in the rotating convex groove 14. A threaded hole 17 corresponding to the through hole 13 is also provided on the side wall of the knob 15. Rotating the knob 15 can make the rotating convex ring 16 rotate in the rotating convex groove 14 so that the knob 15 can achieve positioning rotation. In conjunction with the threaded hole 17 on the upper side wall, the threaded short rod 21 can be moved laterally.

[0027] like Figure 5 As shown, a sliding block 19 is fixedly installed on the top surface of the movable plate 18, and the sliding block 19 is movably installed in the sliding opening 12. A limiting plate 20 is fixedly installed on the inner side wall of the movable plate 18, and the limiting plate 20 is inserted into the limiting opening 8. A threaded short rod 21 is fixedly installed on the outer side wall of the movable plate 18, and the threaded short rod 21 passes through the through hole 13 and is threadedly connected to the threaded hole 17. The threaded short rod 21 will move inward through the through hole 13 and along the threaded hole 17, and push the movable plate 18 to move synchronously. The sliding block 19 on the top surface of the movable plate 18 will slide in the sliding opening 12 until the limiting plate 20 installed on the inner side wall of the movable plate 18 is inserted into the limiting opening 8. Then, the elastic restraint strap 9 can be fixedly connected to the replaceable frame-type sports goggles.

[0028] like Figure 3 As shown, the overall structure of the sports goggle body 1 is hollow. Through the hollow structure design of the sports goggle body 1, the sports goggle can play a role in buffering and absorbing energy when it is impacted, as well as ventilation and anti-fogging.

[0029] Lens 3 includes plane mirrors and spherical mirrors. The specific operating principle of the wearable mechanism 5 in conjunction with this replaceable frame sports goggles is as follows:

[0030] When a plane mirror or spherical mirror lens 3 is needed, or when a damaged lens 3 needs to be replaced, the frame 2 with the required lens 3 can be magnetically attached to the front end of the sports goggle body 1 via the magnetic block 6 installed on the opposite side of the sports goggle body 1. During magnetic attachment, the frame 2 can be further fixed to the front end of the sports goggle body 1 via the buckles 4 on both sides of the sports goggle body 1, so as to facilitate the replacement of the sports goggle frame 2 according to actual usage needs. After replacement, the sports goggle with the replaced frame 2 can be put on the head by the elastic strap 9 and the elastic force of the elastic material of the elastic strap 9. The sports goggle will be bound to the head by the reverse elastic force of the elastic strap 9.

[0031] When the elastic band 9 loses its elasticity, is damaged, needs to be replaced with an elastic band 9 of different strength, or needs to be cleaned, rotate the knob 15 located on the outer wall of the vertical part of the L-shaped side plate 11. The knob 15 will drive the rotating protrusion 16 on the inner side wall to rotate within the rotating protrusion 14 opened on the outer wall of the vertical part of the L-shaped side plate 11. During the positioning rotation, the knob 15 will force the threaded short rod 2 through the threaded hole 17 opened on the side wall. 1. After passing through the through hole 13, it moves outward along the threaded hole 17. During the movement, the movable plate 18 moves outward synchronously on the bottom surface of the lateral part of the L-shaped side plate 11. During the movement, the sliding block 19 installed on the top surface of the movable plate 18 will slide within the sliding opening 12 opened on the top surface of the lateral part of the L-shaped side plate 11 until the limiting plate 20 installed on the inner side wall of the movable plate 18 moves out from the limiting opening 8 opened on the side wall of the positioning plate 7 installed on the side wall of the sports goggle body 1, and the knob 15 can no longer be turned. After rotating, remove both ends of the elastic restraint strap 9 that is fitted onto the positioning plate 7 through the positioning port 10, and move it out between the positioning plate 7 and the limiting plate 20. The elastic restraint strap 9 can then be removed and reinstalled onto the sports goggles. After inserting the positioning plate 7 into the positioning port 10, rotate the knob 15 in the opposite direction to push the movable plate 18 through the threaded short rod 21 until the movable plate 18 is inserted into the limiting port 8. The elastic restraint strap 9 can then be connected and fixed together with the sports goggles for use. This facilitates the disassembly and replacement of the elastic restraint strap 9, allowing for timely replacement when the elasticity of the elastic restraint strap 9 is lost, damaged, or when it needs to be replaced with an elastic restraint strap 9 of different strengths, or when the elastic restraint strap 9 needs to be cleaned. This ensures that the user can wear and use the replaceable frame sports goggles stably and securely through the wearing mechanism 5, thereby improving the effectiveness of the replaceable frame sports goggles.
