Abstract
The utility model provides a fluid-gas transition life-saving air bag, the structure of which comprises an aeration device, which consists of a casing and a liquid tank, and an air bag. The external side of an aeration port of the casing is provided with the air bag with a valve, and the internal side of the aeration port has a thimble, which is used for opening a one-way valve of the liquid tank. The liquid tank arranged in the casing is provided with the one-way valve on the head, and the high-pressure fluid, which can be converted into gas, e.g. ammonia gas etc., under the normal temperature and pressure, is contained inside. When in use, the liquid tank in the casing is pressed to the direction of the aeration port, the one-way valve of the liquid tank is opened by the thimble and the high-pressure fluid in the can flows to the aeration port, so that the air bag is inflated. With simple structure, small volume, convenient carrying and operation, the utility model can be made into life buoy or life jacket type and is properly used in various on-water operations or swim.
Description
Technical field:
The utility model belongs to lifesaving appliance in danger in a kind of water, particularly a kind of life saving air bag.
Background technology:
Present stage, the most frequently used life saving apparatus that arrives when life jacket or buoy quoit are operation at sea or swimming.But existing life jacket or buoy quoit volume are bigger, carry, use and cause a lot of inconvenience.
Summary of the invention:
The purpose of this utility model provides a kind of life saving air bag of liquid-gas shift.Need only Push switch when the people is in danger in water, this life saving air bag just can be inflated automatically, forms air bag, buoy quoit or life jacket, helps it to be out of danger.
The technical solution of the utility model is: a kind of life saving air bag of liquid-gas shift, its structure comprises gas filled device and air bag, it is characterized in that described gas filled device is made up of shell, fluid reservoir, the head of shell is provided with an inflation inlet that has seal ring, the outer end of this inflation inlet is set with and has the valve air bag, and inflation inlet the inner is provided with a thimble that is used to back down the fluid reservoir check valve; Described fluid reservoir is sleeved in the shell, and its head is provided with check valve, and the highly pressurised liquid that becomes gas under the normal temperature and pressure is equipped with in its inside, as ammonia etc.Like this, fluid reservoir will be installed during use in the enclosure push to the inflation inlet direction, thimble just backs down the check valve of fluid reservoir, jar inner high voltage flow direction inflation inlet, and simultaneously because the reduction of pressure forms gas, thereby with airbag aeration.
Liquid provided by the utility model-gas shift life saving air bag is simple in structure, carries easily, can make the form of water wing or life jacket.As long as push fluid reservoir when getting into danger in the water, highly pressurised liquid will discharge rapidly, gives the inflation of water wing or life jacket, and is easy to operate, use when being fit to various operation at sea or swimming.
Description of drawings:
Fig. 1 is the structural representation before the inflation of this life saving air bag.
Fig. 2 is the structural representation after the inflation of this life saving air bag.
The specific embodiment:
Below in conjunction with accompanying drawing embodiment is elaborated.As shown in Figure 1, this liquid-gas shift life saving air bag is made up of gas filled device and air bag.Described gas filled device is made up of shell 1, fluid reservoir 3, and fluid reservoir is sleeved in the shell during use.The head of shell 1 is provided with an inflation inlet 5 that has seal ring, and air bag 1 is socketed on this inflation inlet.Inflation inlet 5 the inners have a thimble 6.Fluid reservoir 3 heads are provided with check valve 4, and its inside is filled with the highly pressurised liquid that becomes gas under the normal temperature and pressure, liquid ammonia etc.When fluid reservoir advanced to head, the check valve of its head was pushed open by thimble, jar inner high voltage liquid by inflation inlet with airbag aeration.The said air bag of the utility model also can be made the form of buoy quoit or life jacket, and is convenient during use.
In an embodiment, the rear portion of shell 1 is provided with Location resilient piece 7, can not withdraw from after fluid reservoir is advanced inwards, as shown in Figure 2, thereby can keep thimble all the time check valve to be backed down after it is advanced, and can not unclamp, and keeps inflated condition.Under this structure, the front end of shell must be detachable, and fluid reservoir takes out from front end.
Claims (4)
