Description

Knapsack formula is aerifyd back of body and is floated

Technical Field

The utility model relates to a technical field of sports and educational outfit particularly, indicates a knapsack formula is aerifyd the back of the body and is floated.

Background

The swimming back float for children mainly has the advantages that extra buoyancy is added to children during swimming learning and playing with water to ensure safety and prevent drowning, the swimming back float for children in the current market is basically formed by superposing and combining foamed EVA (ethylene vinyl acetate) plates, and the buoyancy of the children in water is increased by the way that one back belt penetrates through a plurality of EVA combined plates and fixes the EVA combined plates on the back of the body of the children. The three defects of the product exist at present, the first fixing mode and the second fixing mode are similar to a mode of embracing a big tree with two hands for fixing, the biggest problem is that the back float cannot be firmly attached to the body in water, and the back float can float and swing back and forth along with the impact of water flow due to the fact that the back float is fixed by embracing the body with one back belt, so that the back of a child is impacted by the shaking of the back float, and the back of the child has stronger unstable feeling. Secondly, the volume of the foaming EVA board is fixed and invariable, and the foaming EVA board occupies a fixed space regardless of carrying and storage. Thirdly, although the foaming EVA board is made of foaming materials, the foaming EVA board has certain hardness and is not easy to deform, and therefore the foaming EVA board can be bound on the back of a child to have strong discomfort.
