Described capping comprises lid, and the inside face of described lid has the 4th screw thread matching with the second screw thread.

Further, described capping also comprises cock body, and one end of described cock body is fixedly connected with lid, and the other end is inserted in bung.

Preferably, one end that described lid inserts bung is connected with boss, has for placing the second annular groove of the 3rd seal ring on the outside face of described boss.

Further, on the outside face of one end that described cock body is connected with lid, have the 5th screw thread, on the inside face of described coupling link, have the 3rd screw thread matching with the 5th screw thread.

Further, the inner side of bulge loop is fixed with the 4th seal ring, and described the 4th ring set is on described cock body.

Preferably, on the outside face of described coupling link, be fixed with handle.

Advantage and the good effect that the utlity model has are: the poted assemblies that the utility model provides, and simple in structure, volume is little, productive costs is low, good airproof performance, can conveniently be installed on the bung of Plastic Drum.The utility model adopts coupling link to connect bung and capping, does not require the height that increases Plastic Drum bung when meeting air-proof condition, has reduced the manufacturing cost of Plastic Drum.The sealed plastic barrel that the utility model provides, dispose poted assemblies, between each parts, tightly coordinate, coupling link and bung, coupling link and lid, coupling link and cock body, cock body and through hole, quadruple sealing altogether, guarantee the tightness of storage area, made that liquid is unlikely to be evaporate into outside Plastic Drum, eliminated potential safety hazard.

The specific embodiment

In order better to understand the utility model, below in conjunction with the specific embodiment and accompanying drawing, the utility model is conducted further description.

As shown in Figure 1-Figure 3, a kind of sealed plastic barrel 4, comprises cylindrical shell 401, bung 402 and is arranged on the poted assemblies on bung 402.On the outside face of bung 401, have bung screw thread 4021.

Poted assemblies comprises coupling link 1, capping 2 and four seal rings.In present embodiment, seal ring is O RunddichtringO.

On the inside face of one end of coupling link 1, have the first screw thread 101 matching with bung screw thread 4021.On the inside face of coupling link 1, near the first screw thread 101 places, have in the first annular groove 104, the first annular grooves 104 the first seal ring 301 is housed.On the other end of coupling link 1, be connected with bulge loop 105, bulge loop 105 is one-body molded with coupling link 1.The external diameter of bulge loop 105 is less than the external diameter of coupling link 1, and the internal diameter of bulge loop 105 is greater than the internal diameter of coupling link 1.The 3rd seal ring 303 is equipped with in the outside of bulge loop 105, and the 4th seal ring 304 is equipped with in its inner side.Coupling link 1 is connected with on the outside face of one end of bulge loop 105 and has the second screw thread 102, has the 3rd screw thread 103 on the inside face of this one end.On the outside face of coupling link 1, be also fixed with handle 106, handle 106 is conveniently rotationally connected ring 1.
