Load-adjustable swimming auxiliary device

Abstract

The invention discloses a load-adjustable swimming auxiliary device. A front shaft is arranged at the front end of a device body which is cylindrical after being inflated, and the front shaft is connected with a lifting ring. Wing panels are arranged on the device body, and the wing panels are of a streamline structure and are symmetrically distributed. A pipe shaft at the rear end of the device body is sleeved with a shaft sleeve, and the shaft sleeve and the pipe shaft are in loose fit and can flexibly rotate. Wing-shaped and inclined-angle-adjustable rotor wings are arranged on the outer wall of the shaft sleeve, the rotor wings are symmetrically distributed on the shaft sleeve in a streamline shape, and a rotor wing ring is arranged on the outer edges of the rotor wings to form an integral component. A detachable rotary cover is arranged on the pipe shaft to achieve sealing and is provided with an air nozzle. The load-adjustable swimming auxiliary device is made to rotate by ingeniously using the fluid mechanics principle, the safety of swimming can be effectively ensured, the dynamic effect and interestingness are enhanced, the training load can be adjusted, the exercise intensity can be easily, suddenly and remarkably increased or reduced, various functions of swimming safety, interestingness, the dynamic effect, training and the like are integrated, and the load-adjustable swimming auxiliary device is ideal and wide in prospect.
