Problems solved by technology

[0002] When people swim, they need to paddle with their limbs, which requires a lot of physical exertion. Even if they use fins, their human body structure cannot fully adapt to this swimming method, and they need to go through certain training before they can master them.
In addition, the patent No. is 92107167.1, a kind of pedal swimmer, although the design is ingenious, but its volume is huge, transmission efficiency is low, and there are certain deficiencies.
There is no simple and efficient swimming aid at present

Embodiment Construction

[0007] exist figure 1 It can be seen that the casing 1 of the present invention is a cylinder with upper and lower openings, the inner upper end is supported by the upper bracket 2, the lower end is supported by the lower bracket 3, and the middle of the two brackets has a hole and a mandrel 4 is housed.

[0008] The working principle is briefly described below.

[0009] When in use, the back frame 14 is close to the chest and abdomen, the braces 15 are placed on the shoulders, and the feet are placed in the pedals 17, so that the present invention can be fixed on the human body. In the water, the two feet of a person cycle through the pedal 17, and the power rope 10 is pulled and loosened like a saw. If one end of the power rope 10 is pulled, the upper power wheel 8 rotates in the opposite direction, and the upper ratchet 6 drives the transmission 11 and then drives the propeller 12. Reverse rotation, the lower power wheel 9 is forward rotation; then, when pulling the other ...

Abstract

The invention discloses an auxiliary device of swimming. A casing is a cylinder, the upper part and the lower part of the cylinder are not sealed, the upper end of the inside is supported by an upper bracket, the lower end is supported by a lower bracket, an upper power wheel and a lower power wheel are installed at the inside, the side faces of the upper power wheel and the lower power wheel are both provided with double grooves, and power is transmitted to the power wheels and ratchet wheels by foot pedal power ropes and then is transmitted to a screw propeller so as to realize forward reactive force. As the invention skillfully designs a transmission mechanism, a both-foot circular water pedaling motion is naturally transformed into the rotation of the screw propeller, thereby providing forward boosting; moreover, the invention has compact structure, is convenient for loading and unloading, saves the physical strength and also enhances the pleasure of swimming, and people feel very comfortable when using the invention.

Description

technical field [0001] The invention relates to a swimming auxiliary equipment, in particular to a swimming auxiliary training equipment. Background technique [0002] When people swim, they need their limbs to stroke the water, and their physical exertion is relatively large. Even if flippers are used, the human body structure cannot fully adapt to this swimming method, and they must be trained to master when used. In addition, the patent No. is a kind of pedal swimmer of 92107167.1, though ingenious in design, its bulky, transmission efficiency is low, has certain weak point. There is no simple and efficient swimming aid at present. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art and provide a water swimming aid with compact structure, reasonable design, low cost and easy use, which can make swimming in water fun and save energy. [0004] The scheme adopted by the present invention is as follows: th...
