Embodiment approach

[0087] As an implementation, the gate body 240 is a spherical structure (not shown), such as the one-way valve in some hydraulic valves often adopts this structure;

[0088] As another implementation, as in image 3 and Figure 4 As shown in , the gate body 240 is a plate-shaped structure, and the plate-shaped structure is provided with a third through hole 240-1, and the fastener 23 is passed through the third through hole 240-1. The fastening member 23 pierced through the third through hole 240 - 1 has a positioning and guiding effect on the gate body 240 of the plate-like structure, and prevents fluid leakage in the airbag body due to deviation during use.

[0089] Please continue to refer Figure 5 to Figure 11 , specifically, the shaft retraction mechanism 30 includes:

[0090] The first exhibition body 31 is provided with two first turning ears 311 at intervals, and a plurality of first clasps 312 are provided on its side;

[0091] The second exhibition body 32 is pr...

Abstract

The invention discloses a near-drowning life saving bracelet which comprises a folded belt-shaped airbag body. The airbag body comprises an open end and a sealed end, and the sealed end is detachablyfixed to the airbag body. The near-drowning life saving bracelet further comprises a one-way medium circulating mechanism, a rotating shaft folding and unfolding mechanism and a gas generating substance, wherein one end of the one-way medium circulating mechanism clamps the open end of the airbag body, and external fluid media flow into the open end of the airbag body in one way from the one-way medium circulating mechanism; the rotating shaft folding and unfolding mechanism is movably arranged in the airbag body and is unfolded in the airbag body under the action of external force; and the gas generating substance is arranged in the rotating shaft folding and unfolding mechanism and encounters with the fluid media flowing into the airbag body to generate gas which expands the airbag bodywhen the rotating shaft folding and unfolding mechanism is unfolded. According to the near-drowning life saving bracelet, the problems that an existing life saving bracelet is not convenient to use due to limit of the size and weight, and the potential safety hazard of gas cylinder explosion exists are solved.

Description

technical field [0001] The invention relates to the technical field of lifesaving equipment, in particular to a lifesaving bracelet for drowning. Background technique [0002] At present, there is a wearable life-saving device called Kingii (kingii is a product name in the United States) on the market. Similar products in China are commonly known as drowning self-rescue bracelets. Its working principle is to connect the high-pressure carbon dioxide cylinder and the airbag body through a channel. , there is a striker inside the channel aimed at the seal of the gas cylinder, and there is a wrench on the outside to push the striker to move to the gas cylinder. Inflated by high-pressure gas inside the cylinder, which in turn provides additional buoyancy to the wearer. [0003] The above-mentioned products use high-pressure gas cylinders as the source of inflation gas. Due to the volume and weight of high-pressure gas cylinders, the further lightweight of this type of bracelet i...
