Description

Technical Field

[0001] This utility model relates to the field of ski goggles technology, and in particular to a ventilable ski goggle. Background Technology

[0002] Currently, the ventilation holes of ski goggles are generally fixed on the side of the frame, and their ventilation capacity is fixed. The ventilation level cannot be adjusted. Therefore, in some scenarios where ventilation is less required, the ventilation capacity cannot be reduced to maintain the temperature inside the lens, making it difficult to provide better protection. Similarly, in some scenarios where ventilation is more required, it is difficult to provide sufficient ventilation. After wearing them for a long time, a temperature difference will occur between the inside and outside of the lens, which will cause water vapor to form, affecting the user's vision and posing a significant safety hazard. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a ventilable ski goggle with lenses that can be separated from the frame, so as to provide sufficient ventilation inside the ski goggle.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a ventilable ski goggle, including a frame and a lens disposed in front of the frame. A side buckle assembly is provided between the lens and the frame on both sides. The side buckle assembly includes a connecting seat and a hinge connected to the lens. The connecting seat is connected to the frame via the hinge. The connecting seat has a first groove, and the inner walls on both sides of the first groove have shaft holes. A second groove is provided on the frame corresponding to the position of the first groove. The hinge includes a first hinge portion disposed in the first groove and a second hinge portion disposed in the second groove. The first hinge portion and the second hinge portion are hinged by a pin. A protrusion in the second groove provides damping engagement with the first hinge portion. The principle of this invention is as follows: When air needs to be exchanged inside the ski goggles, the lens is pushed forward by the connecting seats on both sides of the lens. The connecting seats rotate around the hinge, causing the lens to move forward and separate from the frame. A ventilation channel is formed between the lens and the frame, allowing the ski goggles to communicate with the outside world and achieve air exchange. After air exchange is completed, the lens is pushed backward by the connecting seats on both sides of the lens. The connecting seats rotate around the hinge, causing the lens to move backward and fit against the frame. The first hinge part cooperates with the protruding damping to fix the lens.

[0005] As an improvement, the first hinge part includes a body, a fixed shaft head at one end of the body, a movable shaft head at the other end of the body, a toggle block connected to the movable shaft head, and a spring. The body has a receiving cavity, the spring is located in the receiving cavity, one end of the movable shaft head is inserted into the receiving cavity and abuts against the spring, and the fixed shaft head and the movable shaft head respectively cooperate with the shaft holes on both sides of the first groove.

[0006] As an improvement, the upper end of the protrusion is provided with an arc-shaped guide surface, and the outer side of the protrusion forms a limiting surface that presses against the first hinge portion.

[0007] As an improvement, the protrusions are respectively provided at both ends of the second hinge portion.

[0008] As an improvement, a limiting plate is provided on the first hinge part. After the first hinge part rotates away from the protrusion, the rotation angle is limited by the cooperation between the limiting plate and the lens.

[0009] As an improvement, the connector is provided with an embedding groove, and the edge of the lens is located in the embedding groove and locked with screws.

[0010] As an improvement, the side of the connecting seat is provided with an opening communicating with the first groove, and the side of the connecting seat forms a force-receiving part that pushes it forward.

[0011] The beneficial effects of this utility model compared with the prior art are: The hinge structure between the lens and the frame allows for complete separation of the lens from the frame during ventilation, ensuring sufficient ventilation and making operation convenient.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, a ventilable ski goggle includes a frame 1 and a lens 2 located in front of the frame 1. The front of the frame 1 has a connecting surface that mates with the lens 2. The two sides of the frame 1 are connected to the headband respectively. The back of the frame 1 has a sponge frame to increase wearing comfort. The top and bottom surfaces of the frame 1 have perforations and are filled with sponge.

[0017] like Figures 1 to 3As shown, a snap fastener assembly is provided between the lens 2 and the frame 1 on both sides. The snap fastener assembly includes a connecting seat 3 connected to the lens 2 and a hinge. The connecting seat 3 has an embedding groove, and the edge of the lens 2 is located in the embedding groove and locked with screws. The connecting seat 3 and the lens 2 are integrally formed, and the connecting seat 3 is connected to the frame 1 via the hinge. The bottom surface of the connecting seat 3 has a first groove 31, and the side surface of the connecting seat 3 has an opening communicating with the first groove 31. The inner walls on both sides of the first groove 31 have shaft holes. The front of the frame 1 has a second groove 11 corresponding to the position of the first groove 31. When the first groove 31 and the second groove 11 are closed, they can accommodate the hinge, so that the lens 2 can fit snugly against the frame 1. The hinge includes a first hinge part 4 located in the first groove 31 and a second hinge part 5 located in the second groove 11. The first hinge part 4 and the second hinge part 5 are hinged by a pin. The second groove 11 has a protrusion 6 that engages with the first hinge part 4 in a damping manner. The first hinge part 4 includes a body 41, a fixed shaft head 42 at one end of the body 41, a movable shaft head 43 at the other end of the body 41, a toggle block 44 connected to the movable shaft head 43, and a spring. The body 41 has a receiving cavity, and the spring is located in the receiving cavity. One end of the movable shaft head 43 is inserted into the receiving cavity and abuts against the spring. The fixed shaft head 42 and the movable shaft head 43 respectively cooperate with the shaft holes on both sides of the first groove 31. The first hinge part 4 can rotate within the first groove 31. The first hinge part 4 is elongated and has an arc-shaped back, so that it will not interfere with the connecting seat 3 when rotating. The front of the first hinge part 4 is flat. When the first hinge part 4 cooperates with the protrusion, the front of the first hinge part 4 faces the second groove 11, and the toggle block 44 located on the front is correspondingly hidden in the second groove 11. The protrusions 6 are respectively located at both ends of the second hinge portion 5, making the forces on both ends of the first hinge portion 4 more stable. The upper end of the protrusion 6 is provided with an arc-shaped guide surface, and the outer side of the protrusion 6 forms a limiting surface that presses against the first hinge portion 4. After the first hinge portion 4 passes the arc-shaped guide surface, it abuts against the limiting surface, thereby fixing the first hinge portion 4. The first hinge portion 4 is provided with a limiting piece 45. After the first hinge portion 4 rotates away from the protrusion 6, its rotation angle is limited by the cooperation between the limiting piece and the lens 2. When it is necessary to rotate the first connecting part, the side of the connecting seat 3 is pushed, and the first hinge portion 4 is driven by the connecting seat 3.

[0018] The principle of this invention is as follows: When air needs to be exchanged inside the ski goggles, the lens 2 is pushed forward by the connecting seats 3 on both sides of the lens 2. The connecting seats 3 rotate around the hinge, causing the lens 2 to move forward and separate from the frame 1. A ventilation channel is formed between the lens 2 and the frame 1, allowing the ski goggles to communicate with the outside world and achieve air exchange. After air exchange is completed, the lens 2 is pushed backward by the connecting seats 3 on both sides of the lens 2. The connecting seats 3 rotate around the hinge, causing the lens 2 to move backward and fit against the frame 1. The first hinge part 4 cooperates with the protruding damping to fix the lens 2.
