1, owing to adopt and to be threaded, when filling gas the dismounting of connection set loaded down with trivial details, inconvenience influences working efficiency;
2, owing to be to be used for realizing sealing between the charging air inlet of connection set and the gas cylinder valve nozzle by the impacting force that screws the screw thread generation, be hard rays contact seal between charging air inlet and the gas cylinder valve nozzle, when screwing not enough or the two the sealing Line of contact of impacting force that screw thread produces distortion such as wearing and tearing or impression arranged, its sealing effect is very poor, very easily cause to fill gas leakage, unfavorable in safety.
Summary of the invention
At the problem of above existence, the utility model proposes following solution, fill gas cylinder to reach quick connection, raising fills efficient, also has the purpose of good self-sealing function simultaneously.
Technical solution of the present utility model is:
A kind of pressure cylinder fills the selfsealings Quick Connect Kit, the gas tube 2 that comprises gas cylinder valve nozzle 1, band charging air inlet 5, it is characterized in that: the periphery of the valve end of gas tube 2 is with ring locking jaw 4, is with locking jaw cover 3 in the outer ring of locking jaw 4, is used to open and banding locking jaw 4.
Further, ring locking jaw 4 is that the identical circular arc lobe 6 of three lobes combines, intrados at circular arc lobe 6 has internal thread, circular arc lobe 6 can open under locking jaw overlaps 3 effect, and overlap 3 bandings with the outer ring of gas cylinder valve nozzle 1 pawl that carries out being locked again after screw thread docks, meanwhile the charging air inlet 5 of gas tube 2 can be docked with the internal conical surface of gas cylinder valve nozzle 1, realize the fast assembling-disassembling of connection set.
Further, be carved with chute 7, on locking jaw cover 3, be drilled with three screws 8 corresponding, screw in screw 8 and extend in the chute 7, make locking jaw cover 3 do spacing moving and can not deviate from along chute 7 with screw with chute 7 at the outer arced surface same position place of circular arc lobe 6.
Further, be carved with the annular groove 9 of the proper width and the degree of depth, in annular groove 9, embed the seal ring made from plastic material 10 at the annular mouth end face of charging air inlet 5.
Further, be carved with V-shaped groove 11 on an end end face of seal ring 10 embedding grooves, the interior external diameter of seal ring and length and annular groove 9 adapt, and seal ring embeds the degree of tightness appropriateness of groove 9, can slide vertically in groove with seal ring and be advisable.
Further, after the internal conical surface formation of charging air inlet 5 and gas cylinder valve nozzle 1 is docked and is opened gas charging valve, the end face that seal ring is carved with V-shaped groove produces end thrust under the effect that fills gas pressure, the internal conical surface of the other end of seal ring 10 and gas cylinder valve nozzle 1 is compressed closely connected, realize axially from motive sealing; Meanwhile, radially also being subjected to filling the effect of gas pressure of seal ring and produce radial expansion makes the inner arc surface swelling of the exterior arc surface of seal ring 10 and annular groove 9 closely connected, realizes radially from motive sealing, thereby whole connection set is realized from motive sealing.
The utility model advantage is: adopted the Placement of screw thread socket between connection set and the gas cylinder valve nozzle, both realized quick connection, kept with right-handed thread preventing the misloading of inflammable gas and combustion-supporting gas and the function that incompatible gas loads in mixture again; Owing on charging air inlet, set up the seal ring that the band V-shaped groove is arranged, seal ring can be formed from the sealing of expanding under the effect that fills gas pressure again, need not to realize excellent sealing by external force.

Specific embodiments
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is described further:
As shown in Figure 1, a kind of pressure cylinder fills the selfsealings Quick Connect Kit, comprises the gas tube 2 of gas cylinder valve nozzle 1, band charging air inlet 5, and the periphery of the valve end of gas tube 2 is with ring locking jaw 4, be with locking jaw cover 3 in the outer ring of locking jaw 4, be used to open and banding locking jaw 4.
As Fig. 4, shown in Figure 2, ring locking jaw 4 is combined by the identical circular arc lobe 6 of three lobes, intrados at circular arc lobe 6 has internal thread, circular arc lobe 6 can open under locking jaw overlaps 3 effect, make the pawl that is locked again after the outer ring screw thread rapid abutting joint of its internal thread and gas cylinder valve nozzle 1 overlap 3 bandings, to realize the fast assembling-disassembling of connection set.The outer arced surface of circular arc lobe 6 is carved with chute 7, is drilled with three screws 8 corresponding with chute 7 on locking jaw cover 3, screws in screw 8 and it is extended in the chute 7 with screw, makes locking jaw cover 3 do spacing moving and can not deviate from along chute 7.
