<p>A lifebelt. A body thereof is mainly formed by a housing (6) of soft elastic foaming material and a built-in framework (7), and the housing (6) of soft elastic foaming material sleeves the built-in framework (7). Appropriate material performance is used to produce lifebelt for rescuing, and security and protection, and soft elastic foaming material sleeving technology is adopted to solve the problem that a current hard lifebelt inevitably causes injuries and even death once hitting a person calling for help. The built-in framework is used to achieve load bearing strength of over 90 kilograms, external sleeving of the housing of soft elastic foaming material satisfies weight requirements and load bearing strength requirements, and obturator external soft elastic foaming material can also provide enough buoyancy force. The housing of soft elastic foaming material has a fine cushion function when hitting the person calling for help, and therefore does not harm the person calling for help.</p> |
