Abstract

The utility model relates to a water life-saving device, which solves the problem that the existing buoy can not carry out autoinflation. The water life-saving device is provided with a gas storage cylinder and a control valve on the sides of the buoy. A valve rod is movably arranged in a valve body of the control valve. Springs are arranged between the valve rod and the gas storage cylinder. The valve rod extends out of the valve cap. Gas inlet ports on the valve rod are communicated with a side hole d to get into the valve chamber. A gas outlet hole a of the gas storage cylinder is communicated with the gas storage cylinder and the valve chamber. A gas-filled hole b of the valve body is communicated with the valve chamber and the buoy. The gas outlet hole a is corresponding to t-shaped glue on the lower part of the valve rod, and the side hole d extends out of the valve chamber. The utility model has the advantage of simple structure, and is suitable for aquatic sports.

Description

Self saving swimming life saving device

The utility model relates to a kind of emergency device waterborne, particularly a kind of type swimming lifesaving device of saving oneself.

At present can realize automatic gas filed life-saving: as the inflation certainly mostly of military rubber boat, but this series products general technology complexity, raw MAT'L source difficulty costs an arm and a leg, and may popularize into civilian product hardly.

The purpose of this utility model is to provide a kind of and can conveniently folds and wear conveniently, can the automatic easily gas filed type swimming lifesaving device of saving oneself when urgent.

The utility model is finished with following mode:

The type of saving oneself swimming lifesaving device, it includes air bag 1, it is characterized in that gaholder 2 and by-pass valve control being housed at the side of air bag 1, by-pass valve control is by between valve rod 3 and the gaholder 2 spring 6 being housed, with valve gap 4 dress valve rods 3 movable glands in valve body, the valve body gaholder 2 of ining succession, valve rod 3 stretches out valve gap 4, the center of valve rod 3 has induction opening c to be communicated with side opening d on its sidewall, and side opening d displacement is outside the valve pocket of valve body; In the lower end of valve rod 3 T-shaped glue 7 is arranged, it is in the top of the air inlet/outlet a on the gaholder 2, on the sidewall of valve body, there is air-filled pore b to be communicated with the gentle capsule 1 of valve pocket, a film 12 corresponding air-filled pore b are arranged in the air bag 1, the valve of pressure band 10 is arranged on valve body, on pressure valve band 10, there are the valve block 8 of pressure and valve to buckle 9, press valve band 10 to withhold on valve rod 3.Gaholder 2 that air bag 1 side is equipped with and by-pass valve control have one to three.Air bag 1 is circular ring type buoy quoit or life jacket.

The utility model type swimming lifesaving device of saving oneself, it is to utilize to adorn liquid gas in gaholder, in case of emergency, easily by-pass valve control is opened, the liquid gas gasification is expanded charge in the air bag, realize automatic gas filed lifesaving appliance, it will increase the safety of this motion of swimming greatly as swimmer's safety locking motion, alleviate swimmer's psychological burden, it will satisfy this great demand of swimming fan's " raising safety control " as a kind of product.

Fig. 1 is the utility model structural representation.

Structural representation when Fig. 2 is the dress gaseity.

Fig. 3 is the structural representation behind the dress gas.

Structural representation when Fig. 4 is the gas storage state.

Fig. 5 is the structural representation when air bag 1 inflation.

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1, the utility model type swimming lifesaving device of saving oneself adopts the liquid gas gasification to be expanded to the gas filed principle of life preserver, and air bag 1 can be inflatable lifesaving articles for use such as buoy quoit, life jacket among Fig. 1.At first liquid gas is stored in the gaholder 2, buoy quoit (air bag 1) can be folded into a waistband when normal circumstances lies in the waist, when emergency situation is enabled, only need rip control cock, liquid gas expands to gasify and just injects in the waistband, in several seconds waistband (air bag 1) aerification is become a buoy quoit, rapidly the people is emerged and realizes saving oneself.

The utility model save oneself type swimming lifesaving device such as Fig. 1, shown in Figure 2, it is by buoy quoit 1(air bag 1), gaholder 2 two large divisions form, on gas cylinder 2, by-pass valve control is housed, gaholder 2 is close on the buoy quoit 1, air-filled pore b is arranged being close on the position, as shown in Figure 2, buoy quoit 1 is communicated with the valve pocket of by-pass valve control by air-filled pore b, valve pocket is communicated with gaholder 2 by the air inlet/outlet a on the gaholder 2, in the valve pocket of by-pass valve control by gaholder 2 upper valve bodies valve rod 3 is housed, between valve rod 3 and the gaholder 2 spring 6 is housed, with valve gap 4 valve rod 3 activities are contained in the valve pocket, valve rod 3 stretches out valve gap 4, valve gap 4 is contained on the valve body, there is a circle boss to be in the valve pocket at the middle part of valve rod 3, in the inboard of valve gap 4 seal ring 5 is arranged, slit between sealed valve stem 3 and the valve gap 4, there is induction opening c to be communicated with side opening d on its sidewall at the center of valve rod 3, at valve rod 3 during by the free state of spring 6 jack-up, side opening d is in outside the valve pocket, in the lower end of valve rod 3 T-shaped glue 7 is housed, and it is on the air inlet/outlet a on the gaholder 2, after valve rod 3 was depressed, this T-shaped glue 7 was sealed into a that portals.The valve of pressure band 10 is arranged on valve body, the valve block 8 of pressure is arranged on this pressure valve band 10, valve button 9 presses valve band 19 to withhold on valve rod 3, and valve rod 3 is depressed.Seal ring 11 sealed valve caps 4 are connected with valve body, and film 12 is contained in corresponding air-filled pore b in the buoy quoit 1, blocks air-filled pore b when being used to adorn gas.Below with its principle of work of procedure declaration such as dress gas, gas storage, inflations.

As shown in Figure 2, be the dress gaseity, at this moment characteristics are positions that valve rod 3 valve that is provided liquid gas (being called for short the air feed mouth) presses to about 3/4 range, from accompanying drawing 2 as can be seen, air-filled pore b is sealed by plug-hole film 12, and liquid gas will enter from the hole c on the valve rod 3, flows into valve pocket by the side opening d on the valve rod 3, the gap between process valve rod 3, the valve gap 4 and the gap of spring 6 arrive the air inlet/outlet a below the T-shaped glue 7, and flow in the gaholder 2.After filling liquid gas in the gaholder 2, it is removable air feed mouth, after this valve lever 3 is got back to the extreme higher position, as shown in Figure 3, owing to air-filled pore 6 is sealed, under the elastic force effect of spring 6, make seal ring 5 pressurizeds with the clearance seal of valve rod 3 with valve gap 4, and this moment, the side opening 2 sealed circles 5 of valve rod 3 were isolated in outside the valve pocket, and gas does not have circulation path, can not be excessive.After this only need pressure valve button 9 is buckled well, as shown in Figure 4, press valve block 8 that valve rod 3 is pressed to extreme lower position, T-shaped glue 7 is sealed the air inlet/outlet a of gas cylinder 2, and liquid gas is enclosed in the gas cylinder 2, causes this dress gas process and finishes.

Because above process is sealed in liquid gas in the gas cylinder 2, whole device has entered the gas storage state, as shown in Figure 4.

Inflated condition as shown in Figure 5, during inflation, only need rip the valve button, valve rod 3 is got back to the extreme higher position again, as previously mentioned, the sealed circle 5 of side opening d on the valve rod 3 is isolated in outside the valve pocket, valve rod 3 and sealed circle 5 sealings in the gap of valve gap 4, the circulation path of liquid gas has only the air inlet/outlet a outflow from gas cylinder 2, and the air-filled pore b that then flows through enters in the buoy quoit 1, liquid gas gasifies in buoy quoit 1 and expand into gaseous state, and reaches to buoy quoit 1 gas filed purpose.
