Abstract

The invention relates to an inflation-free swimming ring. A ring body is made by means of soft foaming of PU (polyurethane) materials. A seal covering is disposed on the surface of the ring body. Air exhausts generated during soft foaming of PU are arranged at joints of the upper portion and the lower portion of the outer edge of the swimming ring. The inflation-free swimming ring has the advantages of safety, reliability, softness, comfortableness and long service life.

Description

technical field [0001] The invention relates to a non-inflatable swimming ring and a manufacturing method thereof. Background technique [0002] At present, there are two main types of swimming rings, one is the swimming ring with inflatable structure, and the other is the swimming ring with solid structure. The swimming ring with inflatable structure is thin and easy to be punctured by sharp objects, which has certain safety hazards and is easy to be aged and used. The lifespan is short; while the solid structure swimming ring is generally made of foam material, the solid structure swimming ring does not need to be inflated and is safer, but the foam material is not soft enough and the comfort is poor. Contents of the invention [0003] The object of the present invention is to provide a kind of non-inflatable swimming ring, which is made of soft foam of polyurethane material, and the surface of the swimming ring is formed from the sealing skin of the crust, and the vent ...
