Description

Air bag, the built-in automatic inflation bag of airbag

The utility model relates to various air bags, airbag, and the gas filed device of object such as airship, buoy quoit, especially a kind of air bag, the built-in automatic inflation bag of airbag.

Existing needing gas filed object, as various air bags, airbag, and airship, buoy quoit etc., during use, generally is to inflate or by blow slowly inflation with mouth with air pump.If need the gas filed object gas of substituting the bad for the good in advance, very large space to be taken when carrying, otherwise the heavy inflatable tool of band benzene must be taken, very inconvenient.

The purpose of this utility model is at the problem of at present the gas filed object of various need being inflated inconvenience, providing a kind of is placed in the various inflatable objects interlayers, fold, carry with inflatable objects, when inflatable objects is inflated, the inflatable safety draw ring that is exposed outwards need only be pulled out, just can be to inflatable objects inflatable air bag, the built-in automatic inflation bag of airbag.

Air bag described in the utility model, the built-in automatic inflation bag of airbag comprise that upper grooves integral body, lower recess integral body and plastic cement seal barrier film.Upper grooves is shaped on upper groove on the whole, and lower recess is shaped on basic groove on the whole.The upper grooves integrated bottom is shaped on to open splits line.Plastic cement seals barrier film between upper grooves integral body and lower recess integral body.Upper grooves single-piece one end is provided with the semicircle closed head groove that can place the deadend head.Lower recess single-piece one end also is provided with the semicircle closed head groove that can place the deadend head, and the whole other end of lower recess is provided with places the needle-like groove that the threading ring seat is used.Threading ring seat fixed plate cover is pressed on the thimble seat.Link to each other with the closed head groove, be provided with a lead ditch.The two ends that plastic cement seals barrier film are equipped with a backguy earhole.In the upper grooves single-piece upper groove chemical powder is housed, places chemical liquid in the groove of lower recess single-piece basis, plastic cement seals barrier film periphery and lower recess integral sealing.It is fixed that one of total backguy of safety and plastic cement seal barrier film one backguy earhole, the other end is passed the threading ring seat from outside to inside and is sealed the knotting of barrier film other end backguy earhole with plastic cement again, again will this safety total backguy is passed from inside to outside by the pore at a deadend center, and fixes by safe permanent joint and safe draw ring.Upper grooves integral body aligns lower recess integral body, and periphery seals mutually.

In the upper grooves single-piece upper groove chemical powder NaHCO is housed ₃, place chemical liquid C in the lower recess basic groove on the whole ₆H ₈O ₇H ₂O.

This air bag, the built-in automatic inflation bag of airbag can be placed in any two-layer or solid figure air bag, airbag, airship, the buoy quoit, and make this object to be inflatable body and built-in automatic inflation be surrounded by the edge heat seal sealing of deadend head, can supply the usefulness of these object to be inflatable body inflations.

When the object to be inflatable body is inflated, only need the safety draw ring is pulled out, the total backguy of safety spurs the backguy earhole that plastic cement seals the barrier film two ends respectively, just the barrier film that seals that is enclosed on the basic groove can be drawn back from two ends, at this moment the upper grooves chemical powder NaHCO in the groove on the whole ₃Chemical liquid C in falling into basic groove ₆H ₈O ₇H ₂Among the O, chemical change takes place produce a large amount of gases, and make upper grooves opening on the whole split line to break, a large amount of gases are emitted, and make the inflation of object to be inflatable body.

The utility model has the advantages that to be placed in the various inflatable objects interlayers, at any time to the gas filed object inflation of various need.Not the time spent, can fold, need when inflatable objects is inflated, the inflatable safety draw ring that is exposed outwards need only be pulled out with inflatable objects, just can be to the inflation of object to be inflatable body, list is easy to carry between structure, service free, cost is low.
