Problems solved by technology

Whether it is adjustable fins or all-inclusive fins, due to the large surface area, the resistance of the water when swinging back and forth is relatively large, which produces a lot of useless work and is likely to cause ankle sprains, and even cause loss of life and property of the user.

Abstract

The invention provides a flipper and relates to the field of swimming appliances. The flipper comprises brackets, a sleeve and blades, wherein the brackets comprise a peripheral bracket, a vertical bracket and transverse brackets; the vertical bracket is arranged along the center line of the long shaft of the peripheral bracket; the two ends of the vertical bracket are connected with the peripheral bracket; the transverse brackets are perpendicular to the vertical bracket, are connected with the vertical bracket and the peripheral bracket, and divides the space surrounded by the peripheral bracket into a plurality of gaps; the sleeve is arranged at the joint of the vertical bracket and the transverse brackets; the blades are rotationally connected with the vertical bracket and used for opening the gaps when the flipper swings upwards and closing the gaps when the flipper swings downwards; all the blades are correspondingly arranged below the gaps of the brackets. According to the flipper provided by the invention, the blades can only rotate downwards and are limited in upward rotation, so that when in use, the flipper receives small resistance when a foot wearing the flipper is raised. By virtue of the flipper provided by the invention, idle work is reduced during swimming, and a user can use the flipper more conveniently with less effort.

Description

technical field [0001] The invention relates to the field of swimming equipment, in particular to fins. Background technique [0002] Flippers are an auxiliary swimming device that can help people dive and swim. Most of them are worn on the feet. By swinging the feet, the large surface of the flippers is used to push the water to generate power to push the user to exercise. [0003] The flippers in the prior art are divided into: adjustable flippers, which can be adjusted by using the heel strap, but it is necessary to wear diving socks or diving boots so as not to hurt the feet during kicking; all-inclusive flippers, directly Just put it on your feet, no need to buy additional diving boots. The advantage is that it is light and cheap. No matter the adjustable flipper or the all-inclusive flipper, due to the large surface area, the resistance of the water when swinging back and forth is relatively large, which produces a lot of useless work and is likely to cause ankle spr...
