The specific embodiment

Below with reference to above-mentioned accompanying drawing embodiment the utility model is described in detail again.

As Figure 1-3, inflatable life jacket is basic unit 6 with air bag with the PU polyurethane cloth or the PVC of double-deck salmon pink, fix formation air bag 4 with mould through the high frequency heat means of press seals, air bag is that three air chambers 5 that connected by air flue 7 of symmetrical configuration are formed, each air flue and air chamber soaking are pressed with the reinforced rib 9 to convex, there are two air chambers to be distributed in the left side of life jacket in three air chambers, right front chest, an air chamber is distributed in the back, and on an air chamber of shirtfront, be connected with gas filled device, this gas filled device is connected with the gas cylinder 2 of the carbon dioxide compression gas of substituting the bad for the good in advance, is connected with mouth gas blow pipe 8 on another air chamber.

Gas filled device can manually also can be automatic, Fig. 2 is manual gas filled device 3, there is a pressure injection that the inflation seat 15 of inserts 11 is arranged, the hot pressing of inflation seat communicates with air chamber 5 in basic unit 6, on inserts, the seal ring 16 in the inserts is tightly connected both to the gas cylinder 2 of compressed air suits in formation with the screw thread spinning in advance, leaks when preventing to inflate, simultaneously be provided with sealing sheet 14, prevent gas cylinder gas leakage at the gas cylinder oral area.Striker 17 with oblique edge of a knife is installed in the inflation seat of position of bottleneck, and striker is provided with retracing spring 18 and " O " RunddichtringO 19, and " O " RunddichtringO prevents gas leakage when airbag aeration.The striker tail end is with manually torque arm 20 is inconsistent; manually torque arm forms lever-type structure with rivet 21 for hinged being hinged in the inflation seat; stay cord 13 1 ends connect manual torque arm 20; one end connects stay cord hammer 10; the clamp 12 that is plugged in the inflation seat is installed on the stay cord; the effect of clamp shields; prevent to draw by mistake and cause unnecessary inflation; when therefore needing to inflate before entry, must shed clamp earlier and spur the stay cord hammer again, manually torque arm is rotated under the stay cord effect and is made the striker pressurized downward; the edge of a knife punctures the bottleneck sealing sheet; pressure gas in the gas cylinder is promptly to airbag aeration, and inflatable finishes in 5 seconds, forms life jacket.
