Abstract
The utility model discloses a kind of plastic barrel anti-leakage structure, comprise plastic barrel and bung, several annular auxiliary bars are provided with above described plastic barrel, it is characterized in that: described plastic barrel bung edge placement is arc convex, annular catching groove is provided with below described bung, described bung is provided with the clasp with ring buckle slot fit, is provided with the arc-shaped slot coordinated with arc convex inside described clasp, and described arc convex camber ratio arc-shaped slot radian is large.The utility model overcomes the deficiencies in the prior art, project organization is reasonable, plastic barrel bung edge placement is designed to arc convex, and bung designs the arc-shaped slot coordinated with arc convex, and arc-shaped slot radian is relatively little, bung is when covering tightly, notch is subject to relatively large projection extruding and reaches sealing effectiveness, eliminates packing seal, reduces productive costs, add the market competitiveness of enterprise, Applicable scope is wide.
Description
Technical field
The utility model relates to plastic barrel technical field of sealing technology, specifically belongs to a kind of plastic barrel anti-leakage structure.
Background technology
Plastic barrel is used for storage and the transport of various liquid, to special dangerous articles package, there is good characteristic, it has the feature such as non-corrosive, light weight, and oil resistant, the good excellence of performance of being able to bear strong corrosion, and is used for needing insulation, moistureproof, withstand voltage, erosion resisting dangerous articles package.
Existing plastic barrel sealing is by arranging packing seal to seal between plastic barrel and bung, generally just use immediately after characteristic due to plastic barrel article-containing causes unlatching, without the need to secondary seal or the secondary seal time shorter, at this moment packing seal is used to compare waste, the productive costs of relative increase.
Utility model content
The purpose of this utility model there is provided a kind of plastic barrel anti-leakage structure, overcome the deficiencies in the prior art, project organization is reasonable, and plastic barrel bung edge placement is designed to arc convex, bung designs the arc-shaped slot coordinated with arc convex, arc-shaped slot radian is relatively little, and bung is when covering tightly, and notch is subject to relatively large projection extruding and reaches sealing effectiveness, eliminate packing seal, reduce productive costs, add the market competitiveness of enterprise, Applicable scope is wide.
The technical solution adopted in the utility model is as follows:
A kind of plastic barrel anti-leakage structure, comprise plastic barrel and bung, several annular auxiliary bars are provided with above described plastic barrel, described plastic barrel bung edge placement is arc convex, annular catching groove is provided with below described bung, described bung is provided with the clasp with ring buckle slot fit, is provided with the arc-shaped slot coordinated with arc convex inside described clasp, and described arc convex camber ratio arc-shaped slot radian is large.
Described plastic barrel bung edge placement is tapered protrusion, is provided with the conical rebate coordinated with arc convex inside described clasp, and described tapered protrusion taper ratio conical rebate tapering is large.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Plastic barrel bung edge placement is designed to arc convex by the utility model, bung designs the arc-shaped slot coordinated with arc convex, arc-shaped slot radian is relatively little, bung is when covering tightly, notch is subject to relatively large projection extruding and reaches sealing effectiveness, eliminates packing seal, reduces productive costs, add the market competitiveness of enterprise, Applicable scope is wide.
