Butterfly head is arranged outside box 1, and inside is threadedly coupled with bottle cap 3, is punctured part above the bottleneck of gas cylinder 2, rotates butterfly outside
Forming head portion can drive punctured part to puncture the sealing 21 of gas cylinder 2 downwards.
For convenience of carrying, a settable key chain 6 outside box 1, key chain 6 includes ring set 61 and hanging buckle 62, and ring set 61 connects
Box 1 and hanging buckle 62 are connect, for 62 suspended of hanging buckle on waist belt, clothing or other articles, drawstring 53 connects key chain 6, key
Clockwork spring 63 is equipped in button 6, drawstring 53 is connected with clockwork spring 63.Key chain 6 can be used as anti-error-touch device, when not in use,
Drawstring 53 is that relaxation shape in emergency circumstances unlocks ring set 61, so that key chain 6 is detached from box 1, pulls box 1, drawstring 53
It drives runner 52 to rotate, punctures the sealing 21 that needle tubing 51 punctures gas cylinder 2 to drive.
But it is general it is overboard after, be difficult to stay calm and unlock ring set 61, operation difficulty is bigger in water, therefore in box 1
One auto-unlocking device 7 of upper increase can unlock ring set 61 after meeting water automatically, and then facilitate and pull box 1.Auto-unlocking device
7 include a folding key 71 and a push rod 72, and folding key 71 is similar with Foldable key of car, is equipped with key bar 711, turns
Axis 712, button 713 and spring 714, when installation, 61 sets of ring set on key bar 711, key bar 711 is mounted on by a pin shaft
712 side of shaft, key bar 711 and shaft 712 can also be integrally formed, and shaft 712 is mounted on the upper housing at 1 one edges of box
11 and lower case 12 in, the slot and rotary spacing slot of installation shaft are equipped in upper housing 11 and lower case 12, lower case 12 is installed
Spring mounting post is equipped at the spindle central of shaft 712, upper housing 11 is equipped with button hole 12, and spring is loaded onto 713 one end of button
714, it passes through shaft 712 and is inserted into spring mounting post, counter-clockwise rotation two encloses, and then covers shell 11, and button 713 is from upper housing 11
Button hole 13 in expose, upper housing 11 is equipped with card slot 111, and button 713 has a protrusion, and protrusion, which is caught in card slot and can limit, to be turned
Dynamic, by lower button 713, protrusion is detached from card slot, then spring 714 turns round, and shaft 712 and key bar 711 is driven to rotate.
To prevent from accidentally touching the button 713, the present embodiment is arranged lid 73 and closes 13 end face of button hole, passes through push rod 72
Push button 713,72 one end of push rod are against on button 713, wedge mechanism are formed with button 713, as shown, button
713 be inclined wedge, and top surface is inclined-plane, and push rod 72 is sliding block, push rod 72 be ramped up direction it is mobile when, can will be by
Button 713 is pressed.Push rod 72 is mounted in lid 73, slideway 731 is equipped in lid 73, the rear end of push rod 72 is equipped with chance
Water expands adhesive tape 74, and water-swellable adhesive tape 74 is placed between push rod 72 and lid 73, is packed into cunning together with push rod 72
When in road 731, size is suitable (equal or smaller) with slideway 731, will not generate motive force to push rod 72.Water-swellable glue
731 two sides of slideway of 74 installation site of item are provided with permeable hole 732, and after meeting water, water penetrates into water-swellable adhesive tape from permeable hole 732
74, water-swellable adhesive tape 74 is only capable of expanding to 72 direction of push rod, generate to push rod 72 under the limit of slideway 731
It is mobile to button 713 to push push rod 72 for extruding force, to button 713 be pressed, the pop-up unlock of key bar 711.Slideway
Settable idler wheel or sliding rail (not shown) in 731, such water-swellable adhesive tape 74 push push rod 72 more labor-saving.
To prevent water-swellable adhesive tape 74 from making moist when not in use water swelling, it can be added on the outside of permeable hole 732 and meet water and melt
Layer 75 is used as waterproof layer, and meeting water melt layer 75 can be other chance instant materials of water such as common PVA film or starch paper, adherency
In the outside of slideway 731, seal permeable hole 732, meet after water several seconds it is i.e. solubilized.
Box 1 is usually hung at waist belt by user as pendant, as hanging key chain, does not influence work and life
It is living.Once overboard, the water-swellable adhesive tape 74 of auto-unlocking device 7 can squeeze push rod 72, and button 713 is pressed, key is made
Key lever 711 pops up, and ring set 61 can be detached from key bar 711, completes unlock, pulls box 1, and drawstring 53 drives 52 turns of runner
Dynamic, punctured part 511 punctures sealing 21, and compressed gas is discharged out of gas cylinder 2, and via through holes 32 and channel 31 enter in air bag 4, air bag
4 rapid expandings open box 1, continue inflation and form life saving air bag.
It is used in water for convenience of life saving air bag 4, the most of line segment of drawstring 53 relies on clockwork spring 63 to be accommodated in key
In button 6, drowning people pulls out drawstring 53, and promotes the non-return card (not shown) on key chain to block drawstring 53 and prevent retraction,
One end life saving air bag 4 that drawstring 53 connects can float on front, the other end key chain 6 that drawstring 53 connects far from key chain 6
Still it is to be hung at waist belt, drowning people has not only been facilitated to embrace use, but also prevents life saving air bag 4 from drifting out loss.
It is also placed with lifesaving whistle lifejacket light in box 1 and integrates bar 8 and satellite positioning tracker 9, cassette housing is provided with
Compass (not shown), lifesaving whistle lifejacket light integrates bar and satellite positioning tracker is equipped with touching taps, the lifesaving whistle
Lifejacket light integrates bar 8 and is hung on air bag 4 by anti-lost rope system.
The above is only the utility model preferred embodiment, not appoints to the technical scope of the utility model
What is limited, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent variations
With modification, the protection scope of the utility model is still fallen within.
