Abstract

The invention discloses a swimming propeller. The upper end of an U-shaped protective plate (4) is provided with a securing waistband (1), an accelerating box (6) is fixedly arranged on the lower end of the U-shaped protective plate (4), a chain wheel (7) is movably arranged at the lower middle portion inside the accelerating box (6), wheel teeth (10) are arranged at the side edge of periphery of the chain wheel (7), a small gear (11) is movably arranged at the lower end inside the accelerating box (6) by a rotating shaft (13) and a support (12) and movably connected with the wheel tooth (10) at the peripheral side of the chain wheel (7), and a spiral blade (14) is fixed at the lower bottom of the rotating shaft (13). According to the swimming propeller, the large chain wheel is used for driving the small gear, a pedal is used for driving, and thus the spiral blade is driven to rotate and boost; the swimming propeller is fixed on the waist of a person by the U-shaped protective plate and the waistband, fast swimming is thus achieved; the swimming propeller is convenient to use, simple to operate and easy for water rescue and entertainment.

Description

[0001] Technical field: [0002] The invention relates to a swimming propeller. [0003] Background technique: [0004] At present, when people swim in water, they mostly use their arms, palms, legs, and feet to increase their strength, and they also use flippers to speed up swimming. The general swimming speed is limited. [0005] Invention content: [0006] The technical problem to be solved by the present invention is to provide a swimming propeller that adopts a large sprocket to drive a small gear, drives it with pedals, and drives the propeller blades to rotate and boost, thereby realizing fast swimming. [0007] The technical solution adopted by the present invention to solve the technical problem is: a fastening belt 1 is arranged at the upper end of the U-shaped guard plate 4 of a swimming propeller, the acceleration box 6 is fixedly arranged at the lower end of the U-shaped guard plate 4, and the sprocket 7 passes through the central shaft 8 is arranged in the lower...
