In the market, the marine life buoy and the swimming ring have obvious differences and use. A marine life buoy is a kind of water lifesaving equipment, usually made of cork, Styrofoam or other lightweight material with small weight, and is covered with canvas, plastic, etc. The life buoy used for swimming practice can also be made of rubber, filled with air, also known as Rubber band.
The swimming circle is not a life buoy and must not be used as a lifesaving appliance. The national standards for the implementation of the swimming ring and life buoy are not the same, the buoy is a lifesaving function, it has a lot of ancillary functions, and the swimming ring is defined as water toys, the implementation of the toy standard. Therefore, compared with the real life buoy, toy swimming ring easily damaged air leakage, compressive capacity is very poor, very easy to burst, plastic surface water wet slippery, more difficult to grasp, can only play a certain role in the water recreational activities, if brought to the deepwater area is dangerous.
