The specific embodiment

In conjunction with accompanying drawing and embodiment, further structure and the principle of work to the utility model elaborates:

In conjunction with Fig. 1, Fig. 3, Figure 10; A kind of emergent Inflated vest formula life jacket; Comprise vest 90 and liquid gas controller 80; As improvement: described vest 90 has at least two strip shape air bags 93 on the position between under waist to the liquid, and an end of each strip shape air bag 93 all is communicated with at a circle and is arranged in the elongated distribution pipe 92 on the liquid upper/lower positions, elongated distribution pipe 92 be positioned at the position, shirtfront have one with liquid gas controller 80 movable airtight bonded assembly adapting pipes 91; Described liquid gas controller 80 main bodys are liquid gas storage tank bodies 81; There is the intermediate pipe 82 that is communicated with control valve body 87 liquid gas storage tank body 81 belows; Rotary spool 83 is arranged in the control valve body 87; There is outgoing gas connection tube 89 control valve body 87 belows, and outgoing gas connection tube 89 is having a blowdown valve 99 near control valve body 87 places.

As further improvement: described control valve body 87 has switch swing arm 85 in positive outer end on rotary spool 83 axial lines; Outer end, the back side has spring anchor shaft 86 fixing torsion spring 60; Go up right angle turning 61 for one of torsion spring 60 and be pressed against liquid gas storage tank body 81 and intermediate pipe 82 junctions, right angle turning 61 is pressed against in the switch swing arm 85 under the another of torsion spring 60.

As further improvement: described blowdown valve 99 comprises blowdown valve shell 71 and pressure release spring 73 and blowdown valve core bar 74; There is cone 75 one termination of described blowdown valve core bar 74; The described blowdown valve shell 71 inner ends outgoing gas connection tube 89 of ining succession; Have bypass pipe 77 to be connected between blowdown valve 99 and the outgoing gas connection tube 89, there is pressure relief opening 72 described blowdown valve shell 71 outer ends.

As further improvement: the length dimension of described strip shape air bag 93 is 2 to 5 times of self width dimensions, and total volume is 1 to 4 liter after the inflation of all strip shape air bags 93.

Adopt among the embodiment:

Vest 90 has six strip shape air bags 93 on the position between under waist to the liquid, and the length dimension of strip shape air bag 93 is 3 times of self width dimensions, reduces the swimming resistance; Total volume is 2.5 liters after the inflation of six strip shape air bags 93, guarantee that the adult has enough buoyancy below 60 kilograms, and the vertical layout of strip shape air bag can reduce the swimming resistance.

There is a suspension ring circle 88 top, liquid gas storage tank body 81 outsides of liquid gas controller 80, dress liquid freon F12 in the liquid gas storage tank body 81,

There is the intermediate pipe 82 that is communicated with control valve body 87 below, and rotary spool 83 is arranged in the control valve body 87, and there is outgoing gas connection tube 89 control valve body 87 belows, and outgoing gas connection tube 89 is having a blowdown valve 99 near control valve body 87 places.

Concrete use is following:

Fig. 2; Vest 90 is through in the overcoat, fastens soft cord on the suspension ring circle 88, worn behind the necklace liquid gas controller 80 and just weighed down the suspension member that kind and hang over the front as the decorative fitting chest like necklace; Do not affect the appearance and comfort level; With adapting

pipe

91 and 89 airtight linking to each other of outgoing gas connection tube, blowdown valve 99 is between control valve body on the outgoing gas connection tube 89 87 and adapting pipe 91 again, and everything is ready.

In conjunction with Fig. 5, Fig. 6, Fig. 9, Figure 10, the utility model is not when meeting accident drowning need the inflation, and liquid gas controller 80 is in closed condition, and the passage on the rotary spool 83 becomes vertical relation with the passage of intermediate pipe 82.At this moment blowdown valve 99 also is in closure state, and the pressure release spring 73 on the blowdown valve core bar 74 forces the conical surface of cone 75 pressing bypass pipe 77.

Fixing torsion spring 60 on the spring anchor shaft 86 of outer end, control valve body 87 back side; Go up right angle turning 61 and be pressed against liquid gas storage tank body 81 and intermediate pipe 82 junctions for one of torsion spring 60; Right angle turning 61 is pressed against in the switch swing arm 85 under the another of torsion spring 60, guarantees that the normally off of liquid gas controller 80 is under the insurance of torsion spring 60.

In conjunction with Fig. 3, Fig. 4, Fig. 7, Fig. 8; After falling into water in case meet accident, only with hand refers to switch swing arm 85 is rotated up, and switch swing arm 85 driven rotary spools 83 revolve and turn 90 degrees; The passage of passage on the rotary spool 83 and intermediate pipe 82 relation of being in line rotates to open mode from closed condition.Unclamp finger, under the effect of torsion spring 60, liquid gas controller 80 is in closed condition at once again.

Cause hypertonia in the whole air inflator systeies such as strip shape air bag 93 in case deflation time is long; The pressure release spring 73 that sets in advance is inflated in the system pressure and overcomes and compress; The conical surface of cone 75 is leaving bypass pipe 77; Excess pressure gas in the air inflator system will be run away from pressure relief opening 72 through bypass pipe 77, makes that the gaseous tension in the air inflator system is in the whole air inflator system safety allowed bands such as strip shaped air sac 93.
