Description
Technical field
The utility model relates to a kind of holding bottle of liquefied petroleum, relates in particular to a kind of plastic inner container winding gas cylinder bottleneck.
Background technique
The excellent properties such as the plastic inner container winding gas cylinder is lightweight with it, intensity is high, corrosion-resistant have broad prospects in order to substitute traditional metal gas cylinder.But be subjected to the restriction of plastics self intensity, the air outlet of plastic inner container gas cylinder is made by metallic material usually, because modulus and the rates of thermal expansion of bi-material differ greatly, and make the binding site of bi-material the crack can occur because rigidity is discontinuous when suffering cyclic loading; Under the effect of ambient temperature, can produce thermal stress, also can make the connecting part crackle occur, thereby cause gas cylinder gas leakage.
Sealing force between the metal bottle neck of existing plastic inner container winding gas cylinder on the market is the power by self-assembling formation in the moulding, is difficult to control, often causes sealing reliability inadequate, produces easily and leaks.Complicated, the complex technical process of accessory structure has reduced manufacturing efficiency simultaneously.
Summary of the invention
The utility model is inadequate for plastic inner container winding gas cylinder bottle sealing reliability in the prior art, produces easily the deficiency of leaking, and a kind of novel plastic inner container winding gas cylinder bottleneck is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Plastic inner container winding gas cylinder bottleneck comprises the metal bottleneck, metal bottleneck outside is provided with moulding, metal bottleneck and moulding vertically highly consistent, the outside, below of metal bottleneck is provided with annular boss, the annular boss upper surface is the inclined-plane that dips down, moulding is circular, the outer shape of the inboard shape of annulus and metal bottleneck is coincide, the top of the relative annular boss of moulding is provided with the outer body, the upper surface of the outer body inclined-plane that dips down, the outer body is reduced to 3mm-15mm gradually with radial thickness, and the lower surface of outer body is provided with embedded rings, and the both sides of embedded rings are provided with seal ring.
As preferably, the outer side surface of the below of the outer body of moulding is the plastic inner container of blowing, and body top in outer is provided with winding layer, and winding layer is distributed in the plastic inner container outside, and plastic inner container and metal bottle open tightening are in the same place.Whole bottleneck portion only contains integrally manufactured metalwork and moulding, does not have other Component, has reduced the manufacturing of part, and the cooperation space of avoiding a plurality of parts to produce causes gas leakage, has reduced the technique that processing is installed.
The bottleneck of whole plastic inner container winding gas cylinder is only combined by metal bottleneck and moulding, has reduced the installation of Component, and moulding is molding and forming, and the error of having avoided size is so that cooperation between the two is tightr.The metal bottleneck is consistent with the moulding height, and the outside of metal bottleneck all is enclosed with moulding, so that the metal bottleneck is stressed more even, and better tightness.Annular boss is embedded into the inboard of moulding so that combination between the two is more tight, the upper surface of inclination so that moulding in shaping plasticized process can since the spring-back force of plastic deformation so that contact is more tight.The annular boss of the outer body complexed metal bottleneck of moulding stretches out, so that moulding thickness everywhere is approximately consistent, so that stress equalization.The embedded rings of outer body lower surface be used for to connect the injection moulding inner bag, so that the injection moulding inner bag is connected connection with bottleneck tightr.The gradually attenuation of the thickness of outer boss is thinned to 3mm-15mm always, and concrete thickness determines according to the size of winding gas cylinder.The arrangement of seal ring is so that the tightness of whole bottle is better.Outer field winding layer is so that whole winding gas cylinder as an integrated gas cylinder, improves anti-pressure ability and the sealing of gas cylinder.
As preferably, the upper outer of metal bottleneck is provided with the outer and protrudes.The protrusion of outer is embedded in the moulding, so that chimeric connection between the two is tightr, can not occur getting loose.
As preferably, the upper outer of moulding is provided with the outer and protrudes.Protrude along with radially abduction is protruded in the outer of metal bottleneck herein outer, has guaranteed in the consistent situation of moulding thickness answer everywhere, and bottle mouth position forms the plan view of N limit shape, so that bottleneck is more convenient when cooperating with other accessories installations.
As preferably, form bottleneck between the outer of the upper outer of moulding protrusion and the winding layer.Convenient carrying and fastening is convenient to be connected with other equipment.
As preferably, the interior side-lower radial dimension of metal bottleneck is less than the top radial dimension.Metal bottleneck inboard need to other equipment connections so that Inner Dimension is reserved enough greatly.
As preferably, the inside front of metal bottleneck is provided with internal thread.Be used for connecting other equipment.
Make the technique of above-mentioned arbitrary described plastic inner container winding gas cylinder, the metal bottleneck is placed in the mold cavity of injection machine, moulding directly tightly fits in together by molding and forming and metal bottleneck, and then the product of injection formed is seated on the blow-moulding machine, and seal ring is enclosed within respectively the embedded rings both sides of moulding, finish the blow moulding and forming of plastic inner container, at last winding layer is wound into the plastic inner container outside, and the fastening metal bottleneck.Whole technological process is simple, does not need artificial cooperation to install, and has avoided the appearance of alignment error.
According to the plastic inner container winding gas cylinder of the technical solution of the utility model, the accessory part of bottleneck is few, and the sealing of bottle mouth of gas cylinder is high, and bottleneck is difficult for producing leakage.
