Description

Technical Field

[0001] The invention belongs to the field of sports goods, and in particular relates to a headband adjustment structure of swimming goggles. Background Art

[0002] Swimming goggles are worn by users when swimming. Their main purpose is to avoid direct contact between water and eyes, prevent eye pain caused by different tension, allow users to see things in the water clearly, avoid allergies to disinfectants and the spread of diseases, and by wearing swimming goggles, you can also avoid being accidentally hit or kicked in the eyes by other swimmers while swimming.

[0003] The main wearing method of swimming goggles is to cover the two frames of the swimming goggles with the eyes of the user respectively, and then tighten the headband to fix the swimming goggles on the head of the user by utilizing the elasticity of the headband. In order to prevent the swimming strap from loosening during swimming, a stopper is provided on the existing swimming strap to prevent the swimming strap from slipping off again after being tightened. However, the provision of the stopper also makes it difficult to pull the swimming strap when it is tightened, and even causes the worn swimming goggles to slip due to the force, causing water to enter the swimming strap during swimming.

[0004] In order to overcome the above problems, the invention patent "Swimming goggles and headband structure" with publication number TWI720807B and the new patent "Headband adjustment device and swimming goggles" with publication number TWM454225U1 have both improved the headband structure of the swimming goggles. However, the improved structures are mostly focused on adjusting the tooth shape and angle of the buckle teeth, resulting in a large friction force when pulling the swimming strap, causing the worn swimming goggles to slip due to the force, and even increasing the wear rate of the buckle teeth.

[0005] As mentioned above, the current adjustment structure of the swimming strap still has its problems and is not a good design. Therefore, the inventor of this case is eager to improve and innovate it. After painstaking research, he finally successfully developed and completed the head strap adjustment structure of the swimming goggles. Summary of the invention

[0021] like Figure 1 to Figure 4 As shown, the headband adjustment structure of the swimming goggles provided by the present invention mainly includes two adjustment parts 1 and a swimming strap 2. The two adjustment parts 1 each include a connecting portion 11, a positioning buckle 12 and a fixing buckle 13. The positioning buckle 12 and the fixing buckle 13 are arranged on opposite sides of the connecting portion 11 and connected to the connecting portion 11. The fixing buckle 13 includes two extension parts 131. One end of each of the two extension parts 131 is respectively connected to the side of one of the two ends of the connecting portion 11, and the other end of the two extension parts 131 opposite to the connecting portion 11 has a stopper 132 respectively, and the two stopper parts 132 extend toward the direction of the other connecting portion 11, so that the fixing buckle 13 is surrounded by the connecting portion 11, the two extension parts 131 and the two stopper parts 132 to form a through hole 133 that passes through the middle of the fixing buckle 13.

[0022] The positioning buckle 12 includes two compression parts 121 and two positioning parts 122. One end of each of the two compression parts 121 is connected to the side of one of the two ends of the connecting part 11, and the side of the other end of the two compression parts 121 connected to the connecting part 11 extends a positioning part 122 toward the direction of the other compression part 121, and a positioning hole 123 is formed by the two compression parts 121, the two positioning parts 122 and the connecting part 11. The positioning hole 123 is gradually narrowed on the inner wall surface from the end where the two compression parts 121 are connected to the connecting part 11 toward the direction of the two positioning parts 122 to form an inclined surface 1211. In addition, there is a gap 124 between the two positioning parts 122, and a buckle tooth 125 is provided on the surface of the two positioning parts 122 facing the inside of the positioning hole 123.

[0023] A fixing member 21 is respectively provided at the two ends of the swimming belt 2. Each fixing member 21 includes two clamping parts 211 and a penetration part 212. The penetration part 212 is provided between the two clamping parts 211. A side surface of the swimming belt 2 has a plurality of protrusions 22. A positioning groove 23 is formed between each protrusion 22.

[0024] When the headband adjustment structure of the swimming goggles provided by the present invention is assembled, the two ends of the swimming strap 2 correspond to an adjustment member 1 respectively, and each end of the swimming strap 2 is respectively passed through the positioning hole 123 of the positioning buckle 12 in the adjustment member 1, and the surface of the swimming strap 2 with a plurality of positioning grooves 23 faces the direction of the buckle teeth 125 in the positioning hole 123, and one of the positioning grooves 23 on the side of the swimming strap 2 is used to accommodate the buckle teeth 125, and then the penetration portion 212 of the swimming strap 2 is penetrated into the penetration hole 133 of the fixing buckle 13, and the top and bottom surfaces of the periphery of the penetration hole 133 are clamped by two clamping portions 211, so that the fixing buckle 13 is clamped by the fixing member 21 of the swimming strap 2.

[0025] When the headband adjustment structure of the swimming goggles provided by the present invention is used, the length of the swimming strap 2 is adjusted by pulling the swimming strap 2. Figure 5 As shown, when the swimming belt 2 is pulled, the convex portion 22 of the swimming belt 2 passes through the two buckle teeth 125 of the positioning buckle 12, the two buckle teeth 125 and the convex portion 22 act on the two buckle teeth 125 to drive the two buckle teeth 125 to move toward the middle due to elastic deformation, thereby generating a lateral force (stress), so as to drive the inclined surfaces 1211 of the two compression parts 121 to compress the swimming belt 2, so that the swimming belt 2 is subjected to the lateral force (such as Figure 6 As shown in the figure, the swimming belt 2 is compressed and deformed into an arc-shaped state, wherein the swimming belt 2 is compressed and deformed into an arc-shaped state by the lateral force.

[0026] When the swimming belt 2 is deformed into an arc shape by the lateral force, the protrusion 22 on the swimming belt 2 is also bent into an arc shape as the swimming belt 2 is deformed, thereby reducing the contact area of ​​the protrusion 22 with the buckle 125 due to the deformation, so that the swimming belt 2 can quickly pass through the positioning hole 123 and reduce the probability of wear between the buckle 125 and the protrusion 22.

[0027] In summary, the present invention is completely novel, has no similar disclosure or application in the market, and has the value of industrial applicability with substantially improved efficacy, so a patent application is filed in accordance with the law; however, this specification is only a description of the preferred embodiment, and is not used as a definition of the scope of the patent. All modifications and evolutions of the constituent elements under the principles and technologies of the present invention should be covered by the patent scope of the present invention.
