Description

Technical Field

[0001] The invention relates to the technical field of ski goggles, and in particular to a device for quickly disassembling and assembling lenses through a magnetic connection and a pull rope mechanism. Background Art

[0002] Ski goggles are essential for skiing. Because the sunlight reflects strongly on the snow, and the cold wind during skiing can cause great irritation to the eyes, ski goggles are needed to block the sunlight and flying dust to protect the skier's eyes and avoid eye damage.

[0003] The lenses of traditional ski goggles are usually fixed to the frame by screws, buckles or glue. This design has the following problems:

[0004] Disassembly is cumbersome: tools (such as screwdrivers) or complicated operating steps are required, making it difficult to quickly replace lenses while skiing.

[0005] Fragile structure: Frequent disassembly may cause the buckles to wear or the screws to loosen, affecting the stability of the lens and frame.

[0006] Difficult to operate with one hand: Traditional buckles require both hands to press or align, which is inconvenient to operate in cold environments or when wearing gloves.

[0007] Therefore, a pull rope structure that is convenient for lens disassembly needs to be studied urgently. Summary of the invention

[0008] The purpose of the present invention is to solve the problems mentioned in the background technology and provide a pull rope structure that is convenient for disassembling lenses, which is combined with the pull rope mechanism through a magnetic connection to achieve rapid disassembly and assembly of lenses.

The first buckle and the second buckle are used in combination. When the pull rope is pulled outward, the protrusion moves outward, the first buckle is separated from the second buckle, and the lens is separated from the frame.

[0013] As a preferred solution, the blocking cover is connected to the surface of the second connecting groove by a snap-fit ​​connection.

[0014] As a preferred solution, the inner diameter of the spring is larger than the outer diameter of the spring protrusion, and the outer diameter of the spring is smaller than the inner diameter of the spring groove.

[0015] Compared with the prior art, the advantages of the present invention are: simple structure and easy to use; one-handed operation, the lens can be unlocked by simply pulling the pull cord, without the need for tools or complicated steps; stable structure, dual fixation by magnetic attraction and buckle to ensure the stability of the lens after installation; strong durability, the spring and buckle design reduces mechanical wear and extends the service life.

[0030] 1. Structural composition

[0031] Frame and lens: The frame and lens are connected by magnetic attraction. A first connecting groove is provided on the edge of the frame, and a second connecting groove is provided on the side of the lens. The two are nested and matched.

[0032] Lens removal rope mechanism:

[0033] The first connecting groove (frame side): a second buckle is provided on the inner side.

[0034] The second connecting groove (lens side): two spring protrusions are arranged at the inner end, and the outer side is closed by a blocking cover; a pull rope member and a spring are installed inside.

[0035] The pull rope member includes a protrusion, a pull rope fixed to the outside of the protrusion, and spring grooves on both sides of the protrusion; a first buckle is provided on the inside of the protrusion, which is matched and locked with the second buckle of the frame.

[0036] Spring: Installed in the spring slot, with the outer end against the spring protrusion to provide rebound force.

[0037] Blocking cover: fixed to the outer side of the second connecting groove by buckles to prevent the pull rope from falling off.

[0038] 2. Connection method and working principle

[0039] Install the lens: align the second connection groove of the lens with the first connection groove of the frame and push it in. The magnetic attraction will initially position the lens; the first buckle will automatically engage with the second buckle, the spring will rebound under pressure, push the bump back to its original position, and complete the locking.

[0040] To remove the lens: pull the rope outwards, the protrusion moves outwards to compress the spring, and the first buckle is separated from the second buckle; the magnetic attraction is overcome and the lens can be easily removed.

[0041] 3. Key component parameters

[0042] The inner diameter of the spring is larger than the outer diameter of the spring protrusion to ensure that the spring can expand and contract freely;

[0043] The outer diameter of the spring is smaller than the inner diameter of the spring slot to avoid motion interference;

[0044] The blocking cover is tightly connected to the second connecting groove through a buckle to prevent external foreign matter from entering.

[0045] 4. Operation method

[0046] To remove: pinch the drawstring with one hand and pull outwards until the lens comes out of the frame.

[0047] Installation: Align the second connection groove of the lens with the first connection groove of the frame, gently push the lens until it fits magnetically, and the buckle will automatically lock.

[0048] In skiing scenarios, users only need to pull the drawstring to quickly change the lens without taking off gloves or interrupting exercise, which greatly improves convenience and safety. The dual fixation of magnetic attraction and buckle ensures that the lens is stable and does not fall off during high-speed exercise.

[0049] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
