Description

Technical Field

[0001] This application relates to the field of replacement of goggles accessories, and in particular to a replacement structure for the elastic band of a fixed-lens goggle. Background Art

[0002] With the continuous improvement of living standards, people increasingly love outdoor sports. In recent years, extreme sports such as skiing have gradually gained the favor of young people. Skiing requires wearing ski goggles due to environmental factors. On the one hand, it can prevent the strong light and ultraviolet rays reflected in the snow from hurting people's eyes, and on the other hand, it can also play a role in wind prevention and cold resistance.

[0003] Since skiing is a strenuous sport, it requires the goggles to be worn very firmly, and generally an elastic elastic band is used for wearing. A large amount of sweat will be produced during the movement, soaking the elastic band. Over time, the elastic band will produce an odor or mildew, so the elastic band needs to be replaced regularly.

[0004] For the goggles existing in the current market, their elastic bands are often directly sewn on the lenses or assembled through complex structures, making replacement very inconvenient. Utility Model Content

It includes fixing devices provided at one end of the lens and one end of the elastic band for fixing the position of the elastic band on the lens. There are two fixing devices, and the two fixing devices are respectively located at both ends of the elastic band for fixing both ends of the elastic band on both ends of the lens. The fixing device includes a fixing part fixedly connected to the end of the elastic band and a limiting part for fixing the position of the fixing part on the lens. An installation groove for the fixing part to pass through is opened on the lens, and the limiting part is installed in the installation groove.

[0008] By adopting the above technical solution, both ends of the elastic band can be respectively fixed at both ends of the lens through two fixing devices. During installation, directly insert the fixing part of the elastic band into the installation groove on the lens, and then install the limiting part in the installation groove as well. Then the position of the fixing part in the installation groove can be fixed by the limiting part to prevent the fixing part from sliding out of the installation groove. Both installation and disassembly are very convenient, realizing the quick replacement of the goggles elastic band.

[0009] Optionally, the fixing part includes a folding layer formed by folding the end of the elastic band multiple times and a fixing wire fixedly connected to the middle of the folding layer. The fixing wire fixes the folding layer into a whole, and the cross-section of the folding layer is in the shape of an "8".

[0010] By adopting the above technical solution, after folding the elastic band itself and fixing it with a fixing wire, a fixing part integrally fixed with the elastic band can be formed, and the processing technology is simpler and the processing cost is lower.

[0011] Optionally, the installation groove includes an embedding groove for the folding layer to pass through and a first limiting groove opened on one side of the embedding groove. The limiting part is installed in the first limiting groove to fix the position of the folding layer in the embedding groove.

[0015] Optionally, the limiting part includes a first limiting block inserted into the first limiting groove, and the perimeter of one end of the first limiting block is greater than the perimeter of the other end of the first limiting block.

[0016] By adopting the above technical solution, the end of the first limiting block with a smaller perimeter can be smoothly inserted into the first limiting groove, while the other end is stuck at the first limiting groove, thereby realizing the installation and fixation of the first limiting block, and the installation and fixation are more convenient.

[0017] Optionally, the cross-section of the first limiting block is trapezoidal.

[0018] By adopting the above technical solution, the longer the first limiting block is inserted into the first limiting groove, the firmer the fixation is.

[0019] Optionally, the first limiting groove is located at the front side of the embedding groove.

[0020] By adopting the above technical solution, when the fixing part is installed in the embedding groove, the first limiting block is located at the front side of the elastic band, avoiding the elastic band abutting against the first limiting block and causing the first limiting block to move.

Detailed implementation manners

[0035] The following will further describe the present application in detail with reference to the Figures 1-5 accompanying drawings.

[0036] The embodiment of the present application discloses a replacement structure for the elastic band of a fixed-lens goggle. Referring to Figure 1 , the present application is mainly used for replacing the elastic band 3 on the goggle. The goggle includes a frame 2, a lens 1 mounted on the frame 2, and an elastic band 3 mounted on the lens 1. The two ends of the elastic band 3 are respectively connected to the two ends of the lens 1.

[0037] Referring to Figure 1 , the replacement structure for the elastic band of the fixed-lens goggle includes a fixing device 4 provided between one end of the lens 1 and one end of the elastic band 3 for fixing the position of the elastic band 3 on the lens 1. Among them, two fixing devices 4 can be provided, and the two fixing devices 4 are respectively located at the two ends of the elastic band 3 for respectively fixing the two ends of the elastic band 3 on the two ends of the lens 1. The structure of one of the fixing devices 4 will be taken as an example for illustration in the present application.

[0038] Referring to Figures 1 to 3 , a mounting groove 11 for mounting the fixing device 4 is formed in the lens 1. The fixing device 4 includes a fixing part 41 fixedly connected to the end of the elastic band 3 and a limiting part 42 for fixing the position of the fixing part 41 in the mounting groove 11.

[0039] Referring to Figure 3, the fixing part 41 is the part directly connected to the elastic band 3. By folding the end of the elastic band 3 multiple times and using the fixing thread 43 to fix the folded layers, a stable figure-eight structure is formed, which can reduce the processing technology when the fixing part 41 is fixed to the elastic band 3 and reduce the processing cost. Moreover, since the fixing part 41 is formed by the end of the elastic band 3 and is made of a soft material, when in use, it also reduces the wear caused by the fixing part 41 directly abutting against the lens 1 and provides a more stable wearing experience. The fixing thread 43 is made of high-strength nylon thread and is sewn multiple times by a professional sewing machine to ensure its firmness.

[0040] Referring to Figure 2 and Figure 4 , the installation groove 11 includes an embedding groove 111 for the folded layer to pass through and a first limiting groove 112 opened on one side of the embedding groove 111 for installing the limiting part 42 to prevent the fixing part 41 from sliding out of the embedding groove 111 during use.

[0041] Referring to Figure 1 , in this embodiment, the limiting part 42 is a first limiting block 421 with different circumferences at both ends. Its large end can be firmly stuck in the first limiting groove 112, while its small end is convenient for insertion and extraction, thus achieving the effect of quick replacement.

[0042] Specifically, the cross-section of the first limiting block 421 can be trapezoidal, so that the more the first limiting block 421 is embedded in the first limiting groove 112, the more firmly the first limiting block 421 is fixed.

[0043] When the user needs to replace the elastic band 3, just insert the fixing part 41 of the new elastic band 3 into the embedding groove 111, and then insert the first limiting block 421 into the corresponding first limiting groove 112 to complete the replacement. Due to the design of the first limiting block 421, it can fix the position of the installation part in the embedding groove 111 while being able to complete the replacement easily, greatly simplifying the replacement process.

[0044] Referring to Figure 1 and Figure 2 , the first limiting grooves 112 can be arranged at intervals along the length direction of the embedding groove 111. In this application, two first limiting grooves 112 are taken as an example for illustration, and the limiting parts 42 are also provided in multiple numbers corresponding to the number of the first limiting grooves 112, and each limiting part 42 is installed in each first limiting groove 112 one by one. This enables multiple fixings of the elastic band 3, making the force applied to the elastic band 3 more uniform.

[0045] Moreover, in order to prevent the elastic band 3 from driving the first limiting block 421 to slide in the first limiting groove 112 during use, the first limiting groove 112 can be arranged at the rear side of the embedding groove 111, so that during use, the elastic band 3 and the first limiting block 421 are respectively located on both sides of the embedding groove 111, avoiding interference between the two.

[0046] Referring to Figure 5 , a second limiting groove 21 is further arranged on the spectacle frame 2, and the limiting part 42 further includes a second limiting block 422 inserted into the second limiting groove 21. The design of the second limiting block 422 is similar to that of the first limiting block 421, and the circumferences of both ends are different, so that it can be conveniently inserted into and pulled out of the second limiting groove 21. The small ends of the first limiting block 421 and the second limiting block 422 are connected by a fixed connection method, providing a double fixing effect, making the stability of the elastic band 3 during movement better. At the same time, by fixing the first limiting block 421 and the second limiting block 422, the fixing of the spectacle frame 2 and the lens 1 can also be realized, making the installation of the entire goggles more convenient and fast.

[0047] At the same time, when the lens 1 and the spectacle frame 2 are installed together, the first limiting block 421 and the second limiting block 422 are fixed, and the fixing part 41 is clamped between the lens 1 and the spectacle frame 2, thereby increasing the clamping force on the fixing part 41 and making the fixing of the fixing part 41 more firm.

[0048] Among them, both the first limiting block 421 and the second limiting block 422 can be made of magnets, and the small ends of the first limiting block 421 and the second limiting block 422 are designed to be of opposite sexes and have the characteristic of attracting each other. When the small ends of the abutting limiting block and the second limiting block 422 abut against each other, they will automatically adsorb together to complete the fixing of the first limiting block 421 and the second limiting block 422, and the fixing is more rapid.

[0049] The implementation principle of a fixed lens goggle elastic band replacement structure in an embodiment of the present application is as follows: During replacement, directly operate the first limiting block 421 and the second limiting block 422 to move away from each other, so as to release the fixed relationship between the first limiting block 421 and the second limiting block 422, and then directly pull out the fixing part 41 from the installation groove 11. Then take out the new elastic band 3, operate one side of the fixing part 41 to slide into the installation groove 11, that is, make the figure-eight end of the fixing part 41 face the installation groove 11, so that the fixing part 41 can smoothly pass through the installation groove 11. When the fixing part 41 passes through the installation groove 11, the side part of the figure-eight of the fixing part 41 can abut against the lens 1 under the action of the pulling force of the elastic band 3, thereby preventing the fixing part 41 from sliding out of the installation groove 11. Then install the first limiting block 421 on the lens 1, install the second limiting block 422 on the lens frame 2, and install the lens frame 2 on the lens 1, so that the small ends of the first limiting block 421 and the second limiting block 422 are in contact, and the first limiting block 421 and the second limiting block 422 can automatically adsorb together to complete the replacement of the elastic band 3, and the replacement is more convenient and fast.

[0050] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
