Description

TECHNICAL FIELD

[0002] The swimming training waistband is an auxiliary equipment specially designed for water training, usually made of buoyant material, worn on the waist, which can provide additional buoyancy, help beginners or technical practitioners maintain body balance, make leg and core strength training more focused, and can be used to correct swimming posture and reduce fatigue, suitable for children, rehabilitation patients and professional athletes to practice decomposed movements, effectively improving water feeling and swimming efficiency.

[0003] The patent application with application number CN202311785240.2 discloses a swimming training resistance device, which comprises a waistband, a plurality of back-shaped frames are fixed on the outer wall of the waistband at equal intervals, the inside of each back-shaped frame is inserted with a resistance increasing mechanism, and an adjusting mechanism is fixedly connected between the outer wall of the waistband and the adjacent two back-shaped frames.

[0004] In summary, when the exerciser performs swimming training, the existing swimming training waistband needs to adjust the resistance by installing plastic blades with adjustable angles before getting into the water, so that the exerciser cannot adjust the resistance in real time during swimming.

When the user encounters an emergency during training and needs to be immediately removed from the device, the air pump 301 performs rapid exhaust on the floating air bag 101 and the waist clamping air bag 105 through the second connecting pipe 304. In this process, relying on the resistance of water, the floating air bag 101 can be separated from the user's body, thereby avoiding the sustained resistance generated by the floating air bag 101 and the waist clamping air bag 105 to interfere with the user.
