Winding layer is distributed on the outside of plastic inner container, and together with plastic inner container and metal bottle open tightening, the outside of metal bottleneck is enclosed with
Moulding；The upper outer of metal bottleneck is protruded equipped with outer, and the protrusion of outer is embedded into moulding, outside the top of moulding
It is protruded equipped with outer side.The gas cylinder of this kind of structure, metal bottleneck and moulding are connected merely by fitting, connected secured journey
Spend it is low, there are problems that between metal bottleneck and moulding loosen, cause the sealing performance between metal bottleneck and moulding to become
Difference, and be sealed by a seal ring between moulding and plastic inner container, the area of sealing is small, and sealing effect is poor, causes
The gas cylinder of this kind of structure is set to there are problems that gas leakage in bottleneck.
On the other hand, outer mouth is cylinder, is unfavorable for equipment clamping, easy to fall off.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of gas cylinder bottle necks of good airproof performance.
The technical scheme is that：A kind of gas cylinder bottle neck, including Nei Zui and outer mouth, the outer interior mouth of mouth injection molding package, institute
The lower end for stating interior mouth is plugged with sealed inserted piece, and the outer mouth includes outer mouth main body, is set at the top of outer mouth main body lateral wall to extension
The fixed ring stretched and set on the outwardly extending first clamping ring in outer mouth main body lateral wall centre position, the outer mouth main body is in circle
Cylindricality, the fixed ring are in prismatic, and the sealed inserted piece center is equipped with venthole, the link position point of sealed inserted piece and interior mouth
Not She You several annular grooves, be respectively equipped with sealing ring in the annular groove.
Preferably, the interior mouth includes interior mouth main body and is clamped set on lower end on the outside of interior mouth main body outwardly extending second
Ring, described second is clamped on ring with several spaced mounting holes, and first clamping is equipped with embedded cavity, described
Interval is fixed with several fixed columns in embedded cavity, and the second clamping ring is embedded in embedded cavity and fixed column difference
Across mounting hole.
Preferably, the link position of the sealed inserted piece and interior mouth is respectively equipped with first annular slot and the second annular up and down
Slot is respectively equipped with the first sealing ring and the second sealing ring in the first annular slot and the second annular groove.
Preferably, the bottom surface of the sealed inserted piece is equipped with coaxial pillar, and the diameter of the coaxial pillar is less than sealed inserted piece.
Beneficial effects of the present invention：Sealed inserted piece is equipped with sealing ring, and after being installed in place, sealing ring is respectively in inside and outside mouth
The both sides of parting line can effectively prevent influence of the both sides gas to interface；Sealed inserted piece is detachably connected with interior mouth, conveniently more
It changes；Second clamping ring is embedded in embedded cavity, improves the sealing area between Nei Zui and outer mouth, at the same improve Nei Zui and outer mouth it
Between the degree that is connected firmly, to make Nei Zui and outer mouth gluing, sealing always, sealing effect is good, improves the air-tightness of gas cylinder；Gu
It is connected that the setting of fixed column and mounting hole makes Nei Zui and outer mouth mutually be clamped, and increases fastness；Fixed ring is in prismatic, is conducive to outer
Outer mouth is clamped in equipment.
