Lifebuoy tattoo means to take someone as emotional sustenance. Lifebuoy is a kind of life-saving equipment on water, usually made of cork, foam plastic or other light materials with a smaller proportion, wrapped in canvas, plastic and so on. The life buoy for swimming practice can also be made of rubber and filled with air, also known as rubber band.
The swimming ring is not a life buoy and must not be used as a life-saving appliance. The national standards of swimming ring and life buoy are different. Life buoy plays a life-saving role and has many auxiliary functions; The swimming circle is defined as a water toy, which only implements the toy standard.
Therefore, compared with the real life buoy, the toy swimming ring is easy to be damaged and leak, has poor pressure resistance, and is very easy to burst. The plastic surface is wet and slippery in water, which is difficult to grasp. It can only play a certain auxiliary or protective role in water leisure sports. If it is brought to the deep water area, it is dangerous.
