Description

Technical Field

[0001] The utility model relates to the technical field of swimming and diving equipment, in particular to a fin with a thrust-enhancing paddle. Background Art

[0002] Diving is an entertainment activity that is deeply integrated into the modern lifestyle. It allows people to travel underwater, explore the wonderful and exotic underwater world, and satisfy the enjoyment of the spiritual world. Diving can also improve physical fitness and make people's cardiopulmonary function continuously improved and stronger, so it is sought after and loved by more and more people.

[0003] Traditional fins are usually flat in structure, extending outward from the wearing part of the fins to increase the contact area with the water. The propulsion in the water is achieved by kicking the fins back and forth. Although the larger the contact area of ​​the fins, the greater the thrust generated; however, due to the large contact area of ​​the fins, the fins will be subjected to greater downward force when swinging, causing the user to expend more physical energy and swing more times to snorkel.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0005] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a flipper with increased thrust.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A pair of fins with increased thrust paddles comprises a fin body for wearing on a foot, wherein the fin body is provided with a thrust paddle, the thrust paddle is movably arranged at a side end of the fin body, and the fin body is further provided with a limit block for limiting the thrust paddle from continuing to move upward.

[0008] As a preferred embodiment, the thrust paddle and the fin body are integrally formed of a flexible material, and an upwardly recessed bending and swinging groove is provided at the connection between the thrust paddle and the fin body. When the fin body moves upward, the thrust paddle is subjected to the reaction force in the water to swing downward along the bending and swinging groove to release force; when the fin body moves downward, the thrust paddle is subjected to the reaction force in the water to swing upward and increase the obstructed contact area, so that the fin body generates thrust.

[0009] As a preference, the thrust paddle is further provided with a water-permeable hole which passes through from top to bottom, and the water-permeable holes are respectively arranged at the front and rear ends of the thrust paddle.

[0010] As a preference, the number of the thrust paddles is set to at least two, and the two thrust paddles are respectively arranged on the left and right side ends of the fin body.

[0011] As a preference, the thrust paddle is configured to be semicircular in shape, and the inner end of the semicircular thrust paddle is connected to the fin body.

[0012] As a preference, the limit block is configured as a structure protruding to the left and right sides, the limit block protruding above the thrust paddle, and the lower end surface of the limit block abuts against the upper end surface of the thrust paddle to limit it from continuing to swing upward.

[0013] As a preference, the flipper body is further provided with a front plate, which is fixed to the front end of the flipper body, and the rear side end of the front plate abuts against the top of the thrust paddle and restricts it from continuing to swing upward.

[0014] As a preferred embodiment, the front sole of the fin body is provided with a plurality of anti-slip suction cups distributed in an array.

[0015] As a preference, the rear sole of the fin body is provided with obliquely arranged drainage guide grooves.

[0016] As a preference, the left and right sides of the rear end of the fin body are further provided with outwardly protruding fixing ears, and the fixing ears are provided with fixing straps for the wearer to fix the fin on the foot.

[0017] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0018] The utility model has a simple structure and is convenient and quick to use. A front plate and a thrust paddle are provided on the fin body, and the thrust paddle is arranged at the side end of the fin body. A bending and swinging groove is provided between the thrust paddle and the fin body. When the user wears the fins in the water and lifts upward, the thrust paddle is subjected to the reaction force of the water and is bent downward along the bending and swinging groove to reduce resistance, thereby making the upward movement more labor-saving; conversely, when the fins move downward, the thrust paddle is subjected to the force of the water below, so that the thrust paddle is expanded to both side ends, increasing the contact area, thereby increasing the propulsion force, allowing the user to save physical energy in exercise, and providing a faster floating movement effect, meeting the use requirements and having strong applicability.
