Abstract

The utility model relates to a life saving device in water, which has no gas generating device and can be rapidly inflated. Mainly comprises a handle, a pulling plate, a tension ring, a middle clapboard, an air inlet valve body, an adhesive tape and a pulling wire. The rubberized fabric and the pulling plate form an air bag. The air bag is folded in a leather case with the size as a camera at ordinary times, can be hung on the shoulder of a person and is convenient to carry. When the air bag is used, the air bag is stretched by two hands, air enters the air bag from the air inlet valve port, and the air inlet valve is automatically closed after the air bag is inflated. Can be continuously and repeatedly used. The inflation is rapid (2-3 seconds), and the self-rescue device is suitable for water operation, flood fighting and emergency rescue, swimming and other water self-rescue uses.

Description

Portable lifesaver

The utility model relates to a kind of inflatable lifesaving appliance waterborne.

Existing water life saving apparatus, the buoy quoit of makeing as kapok or foamed plastic, life jacket etc., its shortcoming is that volume is big, inconvenience is carried.Use the gas filed life jacket of pressurized air, need wear high-pressure gas bottle, the high-pressure gas bottle heaviness can only disposablely be inflated.Adopt the gas filed life saving apparatus of chemicals, its shortcoming is a complex structure, every use medicine that once need change the outfit, and the subject word of medicine is limited, the expense height.Without chemicals and air bottle also can gas filed " buoyant apparatus that makes things convenient for waterborne " (number of patent application 912141824) its shortcoming be that the check valve that adopts of air inlet is without external force, SELF CL after inflation, when the stretching airbag, the airbag internal pressure is outer more smaller than airbag, the spring resistance that extraneous air overcomes check valve is opened the separate room valve, needs only pressure reduction near balance, and check valve is just closed, the outside air advances not go, so cause the airbag inflation not full.And, cause inflationtime to increase because the gap that check valve is opened in gas replenishment process reduces gradually.Owing to do not have bracing ring between two arm-ties, gas dress folds again at ordinary times again, when stretching the inner space expansion slower, cause inflationtime to increase again, inflationtime reaches 10 seconds.

The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, and providing a kind of does not have gas generating unit and can inflate the full rapidly buoyant apparatus that makes things convenient for.Airbag is folding at ordinary times, does not inflate, and is loaded in the leather sheath packing box as the camera size.Stretch airbag with pulling during use, promptly rapidly aerated (2-3 second), easy to operate, repeated use continuously.

The utility model is achieved in that mainly and is made of arm-tie, median septum, Zhang Quan, adhesive plaster, air inlet valve body.Adhesive plaster and arm-tie are made the osed top airbag.Open circle, median septum, air inlet valve body in airbag.Closing of air inlet valve is after inflation finishes, to close with mechanical control.The air inlet valve body is made of bottom valve shell, piston, rubber cushion, pull bar, piston spring, fixture block, fixture block spring, fixture block backguy.Rubber cushion is connected solid on the piston bottom surface by pull bar, piston moves freely in the bottom valve shell, and spring is contained in the piston, and pull bar is held the piston holddown spring at ordinary times and blocked by fixture block, and valve is in opening.Backguy one end passes fixture block spring (spiral little spring) and connects solid on fixture block, the other end is walked around bottom valve cap edge, and (this edge is smooth, very little with the backguy friction, although the backguy direction of pull almost becomes 90 degree with fixture block advance and retreat direction, but the pulling backguy still is enough to fixture block is retreated) connect admittedly on median septum.When the stretching airbag, spatial expansion in the airbag, pressure reduces, and air enters airbag from the admission port on the arm-tie, airbag is just stretching, and inflation finishes in a flash, and backguy is the past post-tensioning of fixture block, let slip pull bar,, close admission port tight so spring presses piston and rubber cushion to push against ring of admission ports.In airbag, increase again and open circle, support the sectional area in airbag stage casing.It is the same with arm-tie to open the circle oad, and when stretching inflation, the airbag inner space can be expanded rapidly, and inflation is accelerated.Because said structure changes, overcome the weakness that " buoyant apparatus that makes things convenient for waterborne " inflationtime is grown (10 seconds), make inflationtime reduce to 2-3 second.And overcome the not full weakness of inflation.

The utility model further describes below with reference to accompanying drawing:

By accompanying drawing, the utility model by backguy 1, fixture block 2, fixture block spring 3, pull bar 4, piston 5, rubber cushion 6, handle 7, arm-tie 8, bottom valve shell 9, spring 10, open circle 11, median septum 12, adhesive plaster 13, tighten line 14 and constitute.Handle 7 connects solid on arm-tie 8, and adhesive plaster 13 is made the obturator airbag with arm-tie 8.Open circle 11 and median septum 12 in airbag, tighten line 14 adhesive plaster 13 tighten open enclose and median septum outside in the trough of garden.After median septum 12 is tightened line and tightened, innerly cling crack, make whole airbag become two independently air chambers with the rubber cement envelope." many air chambers " more can adapt to the needs of lifesaving in the water.Bottom valve shell 9 connects with arm-tie 8 and is solidified as a whole, and is being equipped with the torus section of four air inlets with the arm-tie connecting place.Fixture block 2 can be free to advance or retreat, and the effect of fixture block spring 3 is fixture block is resetted and to block pull bar 4.Handle 7 stretching airbags, just stretching, backguy 1 is the fixture block 2 past post-tensioning (length of backguy 1, be when airbag is just stretching, can let slip pull bar 4) fixture block 2 toward post-tensioning, rubber cushion 6 compresses admission port under spring 10 effects, inlet close promptly is full of air in the airbag.During venting, the pull bar bottom that press...withes one's finger, pull bar is blocked by fixture block again.When folding, airbag is contained in the packing box as accordion one-level level crimping.As stated above, both sides handle 7 can be inflated again.Repeated use, inflation repeatedly.

Claims
