Immediately inflating swimming life-belt
When being a kind of swimming, uses the utility model, and can instant gas filed safety device for life-saving.
For natatory people, carry in advance gas filed or very inconvenient less than the lifesaving appliance of the material of water with proportion, the influence enjoyment of swimming.And natatory people may drown equally and dies.Instant gas filed lifesaving appliance is easy to carry, occurring when unexpected again can lifesaving, and this device is made up of gas generator and the air bag that is attached thereto, is wound in a certain position of health during swimming, start gas generator when accident occurring to airbag aeration, just can realize saving oneself.Gas generator in a kind of known technology (CN85 2 05258U) is: the gas of liquefaction is easily sealed up for safekeeping in Pressure Container with fusible alloy, center on heating by heating system, heating system is made up of dry storage battery and heating wire or thermal element, connect heater circuit in the time of need saving oneself, the fusion fusible alloy, make blue gas charge into air bag, in order to prevent that hot thing from causing gaseous combustion, need at butane, add fire extinguishing agent or sulphur dioxide such as alkyl halide in the liquid such as butylene, can also connect a stay cord on fusible alloy, those have the swimmer of certain strength can exert oneself a fusible alloy that clogs the mouth of pipe is pulled out when heating system contingency is malfunctioning.Above-mentioned design-calculated shortcoming is that gas generator can not repeated usage, complex structure, and the reliability of startup is low, causes burning easily, also need take precautions against fire, the weight of carry-on articles when carrying dry storage battery and having increased swimming again.
The purpose of this utility model provides a kind of repeated usage of being convenient to, and is simple in structure, and it is reliable to start sensitivity, and aeration speed is fast, the instant inflation swimming life-saving belt that weight is little.
Feature of the present utility model is: the gas generator of life belt is a closed container, on wall of container, have one with the general identical valve of gas lighter inflation inlet principle, it both can be used to charge into blue gas in container, can fill blue gas in the container to air bag again, the bore of the bore of valve and commercial gas lighter inflator pump is complementary, spatial communication in the charging valve of container and the air bag, also can and even all probe in the air bag with the valvular part of container, after emitting, container removal from the air bag can be inflated again with the lighter inflator pump liquid in the gas generator, also can outside air bag, establish one again to the gas filed valve of container, need not when container is inflated its removal from the air bag.The lighter inflator pump can be purchased everywhere, and is gas filed simple to operate, without any need for specified conditions and technical ability, so the extremely suitable repeated usage of life belt of the present utility model; As long as across air bag valve was both pressed down and can need not the alloy fusion processes of above-mentioned known technology to airbag aeration, also need not the course of reaction that other chemical reaction generates gas when needs are saved oneself, aeration speed is very fast; It does not need heater circuit and the battery of energy is provided, and is simple in structure and can further alleviate the weight of belongings in the swimming; Gas does not contact with the hot object of high temperature, does not have the danger of burning, need not to add the particularly harmful sulphur dioxide of fire extinguishing agent; At gas generator a hard objects that valve can be pressed down that can move such as sheetmetal etc. are arranged towards the people side among a small circle, need only one during startup and press gas generator, valve is pressed down and sells position after pressing down, because it is not to seek very little specified point or make very complicated breakdown action with hand, even occurring guaranteeing startup under the unexpected more flurried situation yet.The wall of container of gas generator has transparent material, so that determine to charge into what of blue gas, also can on air bag, establish one in addition and seal aperture easily, at any time check the gas retaining of air bag, can propel the price of air bag for the people of learning swim again and make used for life buoy, if this hole be located at valve on the gas generator right position then neither need to be located in addition air bag outer to the gas filed valve of container, do not need when container is inflated its removal from the air bag yet.The thin neck of inflator pump is probeed into this hole just can be inflated to container.Air bag rubber, the material that permeability to airs such as plastics are low is made, textile is close to the sense of discomfort of article such as rubber, plastics to reduce human body on side lining next to the shin, also available textile covers whole air bag and gains in strength, thereby reduction rubber, the thickness of plastic layer, more satellite is light can to make life belt like this.Air bag should be processed into the shape that is fit to around trunk top, keeps human body to be tending towards in water uprightly, need not conscious activity and just can keep people's head to emerge.When this life belt uses for the women can with swimming costume make interlayer around the chest, life belt is placed in the interlayer.
Be described further by an embodiment below in conjunction with accompanying drawing:
Fig. 1 is the scheme drawing of life belt, and 1 is gas generator among the figure, the 2nd, and valve, the 3rd, air bag, the 4th, the sheetmetal of pressure valve, this sheetmetal press down the back at step 5 places by pinning, need not in the process of airbag aeration, to pin gas generator with hand all the time, make and save oneself that operation is simple whole.
Fig. 2 is the longitudinal sectional drawing that the valve that amplified is crossed its axis, and among the figure 6 is air-filled pores, the 7, the 8th, and rubber pad.When using 9 times pressure valves 2 of inflator pump as shown in Figure 3 to state as shown in the figure, air-filled pore 6 spatial communication in container, liquid had both been realized the inflation to container from the inflator pump input pod.When needs are saved oneself, press gas generator with hand one, human body props up sheetmetal 4 across airbag wall, valve 2 also will be depressed into state shown in Figure 3 (sheetmetal and valve contact position can not be sealed air-filled pore 6) pore 6 space in air bag space and the container will be connected, and blue gas charges into air bag along air-filled pore 6 against the direction when container is inflated.
