Abstract
The utility model provides a barrel cover structure and belongs to a structure on containers as oil barrels and the like. The barrel cover structure is provided with a cover seat which is integrated with a barrel body, an outer cover is mounted outside the cover seat through screw threads, an inner gland is mounted in the cover seat, at least the upper portion of the inner surface of the cover seat is a conical face, at least the upper portion of the outer surface of the inner gland is another conical face which is matched with the conical face on the inner surface of the cover seat. After being mounted on the barrel cover structure, the upper outer cover applies stress on the inner gland to lead the conical faces of the inner surface of the cover seat and the outer surface of the inner gland to be closely attached together to improve sealing effect, contact area between the cover seat and the inner gland is increased by changing a shape of the inner surface of the cover seat and a shape of the outer surface of the inner gland, and the sealing effect is further improved.
Description
Technical field
The utility model provides the structure on the containers such as a kind of oil drum, bucket, chemical bucket, especially a kind of cover structure.
Background technology
At present, cover structure is arranged usually on containers such as oil drum.On this cover structure, have and staving all-in-one-piece cage, by screw thread enclosing cover is installed on the cage, the inside face of cage is a tubular face straight up and down, the outer round surface of internal gland also is a tubular face straight up and down, the imprecision of fitting between internal gland and the cage, and area of contact is little, liquid in the bucket is easy to generate and leaks, and sealing effectiveness is relatively poor.
Summary of the invention
The utility model wants the technical solution problem to be, a kind of cover structure is provided, to improve its sealing effectiveness.
The utility model is to realize like this, a kind of cover structure, it has and staving all-in-one-piece cage, the cage outside is equipped with enclosing cover by screw thread, internal gland is installed in the cage, at least the top of the inside face of described cage is conical suface, the top at least of the outside face of internal gland, another conical suface that adapts for the conical suface with the cage inside face.
Adopt the cover structure of said structure, after loading onto enclosing cover, enclosing cover is exerted pressure to internal gland, make between the conical suface of outside face of cage inside face and internal gland and tightly fit together, improved sealing effectiveness, and the change by cage inner surface configuration and internal gland external surface shape has increased the area of contact between cage and the internal gland, has further improved sealing effectiveness.
Description of drawings
Fig. 1 is the scheme drawing of the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model.
As shown in drawings, a kind of cover structure of the utility model, it has and staving all-in-one-piece cage, the cage outside is equipped with enclosing cover by screw thread, internal gland 3 is installed in the cage, at least the top of the inside face of described cage 4 is conical suface, the top at least of the outside face of internal gland 3, another conical suface that adapts for the conical suface with the cage inside face.
Obviously, the outside face of the inside face of cage, internal gland also can be entirely conical suface.
Described two conical sufaces adapt, and be meant that the tapering of two conical sufaces is basic identical, and the internal diameter of cage are equal to or slightly less than the external diameter of internal gland.
Inboard oriented projecting inward baffle ring 42 at described cage 4 has the warpage that adapts with the baffle ring shape on the internal gland 3.Like this, the lower surface at warpage place can fit together with the baffle ring upper surface, further improves sealing effectiveness.
On the described internal gland 3 warpage that adapts with the baffle ring shape is arranged, be meant that flex location is corresponding with the baffle ring position, and there is the lower surface that contacts with the baffle ring upper surface at internal gland warpage place, the external diameter of the internal gland under warpage is sentenced is equal to or slightly less than the internal diameter of baffle ring.
The using method of this bung no longer describes in detail with existing identical.
Between the upper surface of the lower surface of described enclosing cover 1 and cage 4, flexible gaskets 2 is arranged.After enclosing cover was tightened, flexible gaskets can further improve sealing property.
Lower surface at described enclosing cover 1 is useful on the shackle 12 that hooks flexible gaskets 2.Flexible gaskets is attached on the lower surface of enclosing cover, to improve the comfort feature that this cover structure uses.
The inside part of cage can be the preformed part 41 of rigid plastic material, during making, the other parts of itself and cage is made one.
Outer exterior surface can have fin 11, so that the application of force when rotating enclosing cover.
At the internal gland upper surface lath 31 can be arranged, so that internal gland is taken out.Lath can vertically be provided with, also can horizontally set.
