Swimming lens belt adjusting piece

Abstract

The utility model relates to an adjusting piece for adjusting the length of a swimming lens belt, which is provided with a long-strip-shaped adjusting hole 2, a long-strip-shaped front opening 3 and a straight inlet 4 which are arranged on a plastic adjusting piece 1, and is characterized in that the rear end and the front end of the long-strip-shaped adjusting hole 2 are provided with a zigzag rear lock tooth 7 and a zigzag middle lock tooth 6; sawtooth-shaped front locking teeth 5 are arranged at the rear end of the long-strip-shaped front opening 3, and a plurality of adjusting edges 8 with corresponding distances are arranged on the front face of the head band 9. Due to the structure, the length of the headband can be relatively shortened, and the material cost of the headband is reduced; the structure with only one adjusting hole and the front opening is simple, and the die cost and the material cost are greatly reduced.

Description

Technical Field

[0001] This invention is an adjustment component for adjusting the length of a swimming lens strap. Background Technology

[0002] The length of swimming goggle straps varies from person to person, so an adjustment device is needed to adjust it to the appropriate position. Since the adjusted swimming goggle strap needs to be locked, most existing technologies use multiple wraps to lock it in place, preventing displacement. However, this method is cumbersome, and lengthening the headband to complete multiple wraps is neither costly nor practical. A few methods use a rotating pressure plate and add ridges to the reverse side of the headband to achieve a single wrap, simplifying the adjustment process. However, this requires an additional locking ring to close the headband, making the adjustment mechanism more complex and costly to manufacture. The additional locking ring installation and adjustment during assembly and adjustment still present some inconvenience and affect the appearance. Furthermore, this type of adjustment mechanism is only used at the rear end, while a significant portion of swimming goggle strap adjustments are located at the ends. Summary of the Invention

[0003] The purpose of this invention is to provide a headband adjustment component with a simpler structure, lower cost, and easier operation.

[0004] The technical solution of the present invention is,

[0005] An adjustment component for a swimming headband includes a plastic adjustment component 1 with an elongated adjustment hole 2 adapted to the width of the headband, an elongated front opening 3, and a straight inlet 4. The elongated adjustment hole 2 has a serrated rear locking tooth 7 and a middle locking tooth 6 at its rear end and front end, a serrated front locking tooth 5 at the rear end of the elongated front opening 3, and a number of adjustment ridges 8 at corresponding distances on the front of the headband 9.

[0006] The technical advantages of this invention are that the headband is inserted into the adjustment hole from below and then into the straight inlet of the front opening, so that the two headbands fit together to complete the adjustment and locking tasks. Furthermore, when worn horizontally, the two overlapping headbands naturally press together, eliminating the need for locking rings or similar accessories. In use, it not only has a perfect appearance, but its serrated rear locking tooth 7, serrated middle locking tooth 6, serrated front locking tooth 5, and several adjustment ridges on the front of the headband 9 ensure that the headband tightens more as it is pulled. When adjusting the length, it requires only a single pull in the longitudinal direction, unlike existing technologies where multiple turns are needed. Moreover, since multiple turns are not required, the headband length can be relatively shortened, reducing material costs. This structure with only one adjustment hole and a front opening is also quite simple, significantly reducing both mold and material costs. Attached Figure Description

[0007] The following structural drawings provide a further detailed description of the invention.

[0008] Appendix Figure 1 This is a schematic diagram of the present invention;

[0009] Appendix Figure 2 This is a diagram illustrating how to insert the headband.

[0010] In the diagram, 1 is the adjusting part, 2 is the adjusting hole, 3 is the front opening, 4 is the straight inlet, 5 is the front locking tooth, 6 is the middle locking tooth, 7 is the rear locking tooth, 8 is the adjusting ridge, 9 is the headband, and 10 is the rear hole. Detailed Implementation

[0011] See attached document Figure 1 The adjusting component 1 is made of plastic and has adjusting holes 2 on both the left and right sides, and a front opening 3 on both sides. A rear locking tooth 7 is provided on the rear edge of the adjusting hole 2, a middle locking tooth 6 is provided on the front edge of the adjusting hole 2, and a front locking tooth 5 is provided on the rear edge of the front opening 3. A straight inlet 4 is opened in the middle of the front edge of the front opening 3, allowing the headband to be inserted directly through this straight inlet 4 without having to pass through the front opening 3, facilitating the length adjustment of the headband 9. A rear hole 10 is also provided at the rear end of the adjusting component 1. This is a spare hole. When the total length of the headband 9 needs to be adjusted to a smaller value, resulting in a longer end of the headband 9, the length can be shortened through this rear hole 10, meaning the headband 9 does not pass through the adjusting hole 2 but instead enters the rear hole 10.

[0012] See attached document Figure 2 The crossbeam formed by the front locking tooth 5 and the middle locking tooth 6 leaves a certain space above the headband 6 to prevent it from protruding too much upward. Similarly, a certain space is also left below the crossbeam with the front opening 3, i.e. the direct opening 4, to prevent it from protruding too much downward.

[0013] The headband 9 has an adjustment ridge 8 on the front end, which is used to lock the headband when engaged with the locking teeth. In use, the front end of the headband 9 is inserted into the adjustment hole 2 from below and then inserted into the front opening hole 3 through the straight inlet 4 to lock the headband 9. The operation is that simple. When the headband 6 is put on the head and pulled tight, it is locked in just one turn. The principle is that the headband 9 forms a 90-degree bend in the tightening direction. In addition, the adjustment ridge 8 cooperates with the middle locking tooth 6 and the rear locking tooth 7, so that it locks tighter and tighter as it is pulled. The end of the headband 9 inserted into the front opening hole 3 is not only pressed and not moved, but also pressed against the other headband 9. Compared with the existing technology that requires an extra large loop to make the two headbands 9 stick to each other, this technology saves a component and is simple and beautiful.
