1) snap joint of the prior art, its structure is more complicated, and service life is short；
2) snap joint of the prior art, direct clamping is outside rigid clamping, easy line up outside pipeline when using
Table produces catcher mark and damage, influences the use of pipeline；
3) snap joint of the prior art, direct clamping is rigid clamping outside pipeline when using, sealing compared with
Difference, easily because poor sealing causes channel interior to be intake, influences the use of pipeline；
4) snap joint of the prior art, when pipeline is inflated and detected into water, snap joint need to soak together with product
Enter in water, easily intake because of design reasons, inside snap joint and be difficult purging and clean out, when recycling so that product
Channel interior is intake, and influences the use of pipeline.

In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of inflation inlet of anti-gas-leak, institute
State the front end that inflation inlet is mounted in appendix, it is characterised in that：The inflation inlet include with appendix coordinate screw thread bleeder pipe, with
Rotation nut and be connected to the gas port joint rotated in nut, the appearance of described screw thread bleeder pipe one end that screw thread bleeder pipe coordinates
Face is provided with screw thread, and the rotation nut coordinates with screw thread carries out position adjustments, and the screw thread bleeder pipe other end is provided with extension fore-set,
Extension fore-set is contained in gas port joint, and the front end of the gas port joint is provided with the vent plug coordinated with extension fore-set.
Further, the gas port joint is in funnel-form, and the extension fore-set is by rotating the tune that nut and screw thread coordinate
Section does pushing action in rectilinear tubes.
Further, the tail end of the gas port joint is provided with barb outer, and barb outer is connected to rotation nut
In neck.
Further, the extension fore-set is provided with top opening, and top opening is semicircular arc, a diameter of vent plug arc length of top opening
1/3rd.
Further, the diameter of the vent plug is more than the diameter of screw thread bleeder pipe.
Further, the vent plug is fixed on gas port inner nosepiece wall by soft-plastic material.
Principle：Appendix is fixed in screw thread bleeder pipe by the utility model, by rotating in nut and screw thread bleeder pipe
Screw thread position, 1 is adjusted) rotation nut rotates toward appendix direction, position of the extension fore-set in gas port joint is toward leakage
Struggle against hole propulsion, after vent plug is withstood, continues to press on vent plug so that vent plug and gas port joint formation bleed passage, realizes and deflates；2)
Rotation nut rotates toward gas port joint direction, in extension fore-set retraction gas port joint, drive of the vent plug in soft-plastic material restoring force
And it is interior replied under gas pressure, block gas port joint, carry out gas storage.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model has following excellent
Point：
1st, this practical operation is more convenient, and with adjustability, gas capacity that can be immediately to inside air bag is adjusted
Section.
2nd, beneficial to being deflated in time to life-support back pack, the original state convenient use for reclaiming recover knapsack in time is reached.
