Lifesaving ball

Abstract

A lifesaving ball relates to the field of water lifesaving appliances. The lifesaving ball comprises a bottle body, a partition plate, stirring blades, a firing pin assembly, a rope buckle, a rotatingshaft and an elastic air bag. The elastic air bag is arranged on the bottle opening; the two groups of partition plates divide the interior of the bottle body into a left bin, a right bin and a middle working bin, and the left bin and the right bin are filled with foaming forming materials; the stirring blade and the striker assembly are arranged in the middle working bin, and the striker assembly is in trigger connection with a power switch of the stirring blade; the rope buckle is connected with the firing pin assembly and the elastic separation membrane. The striker assembly is provided with a striker and a pressing spring; the upper portion of the rotating shaft is connected with the top cover, the lower portion of the rotating shaft is rotatably clamped with the bottle body, and thebottom end of the rotating shaft abuts against the striker to compress the pressing spring. When the rotating shaft rotates and is not clamped with the upper shell, the striker moves upwards to strikethe rotating shaft, so that the top cover is opened; and the firing pin continuously moves upwards to drive the rope buckle and the elastic separation membrane to be separated from the separation plate and continuously moves upwards to trigger a power switch of the stirring blade to be turned on.

Description

technical field [0001] The invention relates to the field of water lifesaving appliances, in particular to a lifesaving ball. Background technique [0002] The usual water lifesaving equipment is mostly life jackets, life buoys, and foam buoys, which are relatively large in size and are generally only used when swimming, so it is inconvenient to carry them with you. There are self-inflating wrist-type lifesaving equipment on the market. Although it has certain practicality and portability, it is dangerous because it uses high-pressure bottled liquid gas as the gas source, and its appearance is not small enough. It can be worn while swimming, and the price is relatively expensive. There are not many people who buy and use it, and it cannot protect the crowd anytime and anywhere. There are also various technologies that generate gas through chemical reactions to automatically inflate the airbags. Because of their obvious defects, they are either bulky and simple in appearance...

[0002] The usual water lifesaving equipment is mostly life jackets, lifebuoys, and foam buoys, which are relatively large in size and are generally only used when swimming, so it is inconvenient to carry them with you.

There are self-inflating wrist-type lifesaving equipment on the market. Although it has certain practicality and portability, it is dangerous because it uses high-pressure bottled liquid gas as the gas source, and its appearance is not small enough. It can be worn while swimming, and the price is relatively expensive. Not many people buy and use it, and it cannot protect the crowd anytime and anywhere.

There are also various technologies that generate gas through chemical reactions to automatically inflate the airbags. Because of their obvious defects, they are either bulky and simple in appearance, or the airbags are easy to break, and their safety is not guaranteed, or they contain toxic and harmful substances that are not healthy and environmentally friendly. unable to provide effective protection
