Embodiment
The utility model is described in further detail in conjunction with drawings and Examples.
Conjoined pneumatic bag 1 of the present utility model, is mainly made up of monomer air bag, check valve and inflation road.Referring to Fig. 1~Fig. 2, integral product includes two layers of the high strength plastics film 11,12 fit together（Only for the convenience of diagram, double- layer filmses 11,12 are separated in figure）, it is wide bar shaped；It is composition monomer air bag and the basis for inflating road；Also include being sandwiched in the two layers of narrow bar plastic film 21,22 in the middle of the two layers of plastic thin films 11,12（Only for the convenience of diagram, double-layer filmses 21,22 are separated in figure）, it is the basis for constituting check valve.Because plastics are transparent, the end line up and down of narrow bar plastic sheeting 21,22 is visual in Fig. 1.
Two parallel hot- sealing lines 31,32 are provided with the side of wide bar plastic film 11,12, it irons conjunction plastic sheeting 11,12, constitutes the inflation road 30 of an insertion.Plastic sheeting 11,12 is provided with some perforated lines 40 vertical with hot- sealing line 31,32, and integral product is divided into many monomer air bags 300 by it, and perforated line 40 and hot- sealing line 31,32 are non-intersect, to ensure the connectivity for inflating road 30；Hot-sealing line 32 close to perforated line 40 together with the hot-sealing line 301 located at another three weeks, seals an independent space, constitutes monomer air bag 300 as a sealing margin of each monomer air bag 300.Check valve includes air inlet and gas outlet, and its gas outlet is located in monomer air bag 300, and air inlet is connected with inflation road 30, thus, when being inflated into inflation road 30, via check valve, gas can enter in monomer air bag 300, and can keep holding one's breath, and form several air bags.It is connected between adjacent air bag by perforated line 40, when needing to use air bag, can be easy to disconnect it, facilitate user.
What the check valve was formed by, in Fig. 1, hot-sealing line 32 passes through some oil film pieces 50, those oil film pieces 50 are affixed between narrow bar plastic sheeting 21,22, when being heated along hot-sealing line 32, due to the effect of oil film piece 50, film 21,22 does not iron conjunction in this place, some openings thus are formed, as shown in Fig. 2 this constitutes several air inlets of check valve；In monomer air bag 300, some heat seal points 60 are provided between narrow bar plastic sheeting 21,22 and plastic sheeting 11 or only between narrow bar plastic sheeting 21,22, form the lattice arrangement staggered, air is via the opening into after between narrow bar plastic sheeting 21,22, gap along between dot matrix heat seal point 60, advance tortuously, the lower edge of plastic sheeting 21,22 is eventually disengaged from, into monomer air bag 300；And when the air of entrance is more and more, extruding force is formed, the lower edge of narrow bar plastic sheeting 21,22 is tightly fit together, thus can only allowed air into, and air can not be discharged, this is a kind of embodiment of check valve.
The check valve may also is that composition, referring to Fig. 3, above-mentioned plastic sheeting 21,22 is replaced by layer of plastic film 23, and some oil film pieces are provided between plastic sheeting 23 and plastic sheeting 11, so that not ironing conjunction at this and forming some openings, the air inlet of check valve is formed；In monomer air bag 300, the heat seal point 60 of some lattice arrangements is provided between plastic sheeting 23 and plastic sheeting 11, air along the gap between heat seal point 60 through into after between plastic sheeting 11,23, advancing, until entering in monomer air bag 300；The air of entrance produces extruding force, the lower edge of plastic sheeting 11,23 is tightly fit together, thus air can only be allowed to enter from air inlet, and can not discharge air, and this is second of embodiment of check valve.
The above is only preferred embodiment of the present utility model, any formal limitation is not done to the utility model, although the utility model is disclosed above with preferred embodiment, but it is not limited to the utility model, any those skilled in the art, in the range of technical solutions of the utility model are not departed from, when the technology contents using the disclosure above make a little change or are modified to the Equivalent embodiments of equivalent variations, in every case it is the content without departing from technical solutions of the utility model, any simple modification made according to technical spirit of the present utility model to above example, equivalent variations and modification, in the range of still falling within technical solutions of the utility model.
