Abstract

The invention provides a lifebuoy with an air leakage preventing function. The lifebuoy comprises an inflatable annular main cavity, wherein an annular auxiliary cavity prepared from elastic rubber and coaxial with the annular main cavity is fixedly connected with the upper surface of the annular main cavity; the annular auxiliary cavity and the annular main cavity are connected through an air passage internally equipped with a first check valve, and circulation direction of the first check valve points to the annular main cavity from the annular auxiliary cavity; a second check valve is arranged at the upper part of the annular auxiliary cavity, and circulation direction of the second check valve points to the inside of the annular auxiliary cavity from outside. According to the lifebuoywith the air leakage preventing function, gas in the lifebuoy can be replenished, and safety of a user is guaranteed.

Description

technical field [0001] The invention relates to the field of water lifesaving equipment, in particular to a lifebuoy. Background technique [0002] Life buoys are widely used as water rescue equipment. Usually the shell is made of rubber, plastic and other materials, and the interior is inflated. However, after a long time of use, the life buoy may be worn out, and air leakage may occur, and the slight damage and air leakage are not easy to be detected. , but a lifebuoy that leaks air during use will cause great harm to the user. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an air-leakage-proof lifebuoy, which can supplement the gas in the lifebuoy and ensure the safety of users. [0004] The technical solution adopted by the present invention to achieve the technical purpose is: the anti-leakage lifebuoy includes an inflatable annular main cavity; The annular sub-cavity of the shaft; between the annu...
