Description

Technical Field

[0001] The utility model relates to an anti-skid flipper with easy-to-adjust tightness, and relates to the technical field of flipper equipment. Background Art

[0002] Fins provide powerful forward propulsion for swimming and diving. The wide area of ​​the fins can provide powerful power, eliminating the need to paddling with the hands to generate power, freeing up the hands to engage in other work.

[0003] Traditional fins are mostly straight-through fins, and the corresponding model of fins is selected according to the size of the foot for wearing. However, since everyone's foot size is different, fixed-size fins cannot perfectly match the sizes of different people, and thus there is a possibility of detachment during the wearing process. In order to improve the wearing security of the fins, fasteners are used in the prior art to fasten the wearing part. For example, the patent technology with announcement number CN116726461A discloses a swimming fin, which specifically includes a wearing component, a bionic foot and an elastic reset component. The wearable assembly includes a foot support and a first wearable component, the first wearable component being mounted on the foot support; a bionic foot located at the bottom of the foot support, the rear end of the bionic foot being pivotally mounted on the foot support, the bionic foot extending forward from its rear end and beyond the front end of the foot support; and an elastic reset assembly being mounted on the foot support and connected to the bionic foot. The bionic foot can be rotated from a water-splashing position to a drag-reducing position under the action of the elastic reset assembly. In the water-splashing position, the bionic foot rests against the bottom surface of the foot support, and in the drag-reducing position, an acute angle is formed between the bionic foot and the foot support, facing forward. However, in this solution, the wearable assembly is formed solely by a simple fixing strip to form the first wearable component. While this effectively secures the wearable component, the wearable component is not particularly effective. Long-term water exposure can cause swelling of the foot, and the tightness of the wearable component can cause discomfort, thus affecting the user experience. Furthermore, the wearable component is not well adapted to users with different foot shapes, and the sole lacks a non-slip structure, resulting in low safety. Utility Model Content

[0025] More specifically, a water blocking groove 11 is provided at the bottom of the front end of the fin body 1. During swimming, the water blocking groove can prevent part of the water from flowing backward, thereby increasing the resistance and improving the swimming effect.

[0026] The working principle of the present invention is as follows: when wearing the fins, first loosen the rotary adjustment knob 5 to relax the elastic cord 4. After wearing, tighten the rotary adjustment knob 5 to the appropriate tightness to complete wearing. When it feels too tight or uncomfortable, you can adjust it again. The convenient adjustment makes it easier to wear. During the wearing process, the anti-slip grooves 6 in the fin body 1 can effectively play an internal anti-slip role, and the foot will not slip during the wearing process. At the same time, the anti-slip block 12 at the bottom of the fin body 1 can also play an anti-slip role when walking. During swimming, the water blocking groove 11 can block the water flow, making walking easier.
