Portable waterborne emergency lifesaving device

Abstract

The invention provides a portable waterborne emergency lifesaving device. A chamber in which a foamed material can be arranged is formed in the end of a closed box which can be connected with a strap; a capsule cavity in which a soft airbag can be arranged and is fixedly connected is formed in the other end of the closed box; a foamed liquid material channel for regulating the on-off by virtue of a key switch is formed between the chamber and the capsule cavity; a closeable foamed liquid material injection hole is formed in the outer end of the chamber; a sealing cover expanded to open is arranged at the outer end of the capsule cavity; a strap fastening ring through which the strap can be inserted is arranged on one side of the closed box which can be connected with the strap; and a pull ring capable of pulling the key switch is arranged on one side opposite to the key switch of the box. During use, a polyurethane foamed material is injected into the chamber, the device is fixed on a human body after the box is connected with the strap by virtue of the strap fastening ring, and during waterborne swimming or waterborne operation, the foamed liquid can enter the soft airbag so as to form a solid foamed material by virtue of the key switch during emergency, a water floating effect can be achieved, the device is small in size and convenient to carry, and the formed block is large in size and high in buoyancy.

Description

technical field [0001] The invention relates to a water lifesaving device, in particular to a portable water emergency lifesaving device. Background technique [0002] Now when swimming or working on water, lifebuoys or lifejackets will be directly configured for backup. Existing lifebuoys and lifejackets are all filled with gas or equipped with buoyancy devices with foam block materials. Although they are convenient to use, they are very easy to carry. It is inconvenient, especially for life buoys filled with gas, if you don't pay attention, there will be air leakage and failure. Contents of the invention [0003] The invention provides a portable water emergency lifesaving device, which has the characteristics of convenient carrying, convenient use and good buoyancy effect. [0004] The present invention includes a soft airbag and strap buckle, and the adopted technical scheme is: there is a cavity that can be filled with foaming material in a closed box body end that c...
