Abstract
The invention provides a sealing oil drum which is excellent in sealing performance and overcomes the defect that in the prior art, an oil drum is poor in sealing performance. The sealing oil drum comprises a drum cover, wherein at least one thickening part is arranged on the drum cover, an oil drum hole is formed in the thickening part, an internal nut is fixedly disposed in the oil drum hole and connected with a bolt, and a sealing ring is arranged between the internal nut and the bolt. By the adoption of the oil drum of the structure, the thickening part is arranged on the drum cover, the oil drum hole is formed in the thickening part, and the internal nut is fixedly disposed in the oil drum hole, so that the connecting thread on the oil drum hole is lengthened, and the sealing effect is effectively improved.
Description
?
Technical field
The present invention relates to a kind of oil drum, particularly relate to the sealing oil drum that is provided with seal bore on top cover.
Background technology
Existing oil drum, the sealing arrangement arranging on the dark inspection door of its oil inlet and/or oil adopts the mode that seal ring is set under nut conventionally, if application number is 201220052261.4, name is called a kind of Chinese invention patent of oil drum sealing arrangement, staving place at hydraulic fluid port is provided with negative thread, need to seal oil drum time, on bolt shank, put seal ring, after bolt shank is screwed in screw thread.The oil drum that adopts said structure sealing arrangement, because oil drum wall is thin, so the length of the sealing thread at oil inlet place is short, makes the poor sealing performance of oil drum.
Summary of the invention
The object of the invention is the deficiency for prior art oil drum poor sealing performance, the valued knife sealing oil drum that a kind of sealing property is good is provided.
The object of the invention is to be achieved through the following technical solutions:
A kind of sealing oil drum, comprises bung, is provided with at least one thickening part on described bung, is provided with oil drum hole at thickening part place, in this oil drum hole, is fixedly installed built-in nut, and bolt is connected with built-in nut, between built-in nut and bolt, is provided with seal ring;
On the excircle of described built-in nut, be provided with intermediate step, inner step and outer end step, correspondingly, described oil drum hole is stepped hole, is provided with intermediate step hole, inner stepped hole and outer end stepped hole, and described intermediate step is positioned at described intermediate step hole;
The inner end surface of described built-in nut is arranged in oil drum hole, in the inner in described oil drum hole, the 4th stepped hole is set, and the inner diameter D 1 of described the 4th stepped hole is less than the diameter D2 of described inner step, and the hole of described the 4th stepped hole shoulder is fixedly connected with described inner end surface;
Described built-in nut is across between the inner side and outside of bung;
The head end of described bolt is the U-shaped cylinder of sealed bottom;
The outer face of described built-in nut is concordant with the outer top in oil drum hole.
Adopt the oil drum of structure of the present invention, owing to being provided with thickening part on bung, oil drum hole is arranged on thickening part, and oil drum hole in be fixedly installed built-in nut, so the connecting thread length on oil drum hole increases, increased sealing effectiveness.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, 2, the sealing oil drum of the embodiment of the present invention, comprise bung 5, on bung 5, be provided with thickening part 1, in thickening part, 1 place arranges oil drum hole 6, in oil drum hole 6, be fixedly installed built-in nut 2, bolt 4 is threaded with built-in nut 2, between bolt 4 and built-in nut 2, is provided with seal ring 3.
Embodiment is preferably, as shown in Fig. 2-7, is provided with intermediate step 7, inner step 10 and outer end step 11 on the excircle of built-in nut 2, and the diameter of intermediate step 7 is all greater than inner stepped diameters and outer end stepped diameters.Corresponding oil drum hole 6 is set to stepped hole, and the shape and size of its intermediate step hole 12, inner stepped hole 13 and outer end stepped hole 14 match with corresponding intermediate step 7, inner step 10 and outer end step 11 respectively.Intermediate step 7 is arranged in intermediate step hole 12.Built-in nut 2 is set like this can increase the firmness being connected between built-in nut 2 and thickening part 1, improves sealing effectiveness.
As shown in Figure 2, preferred structure is, the outer face 8 of built-in nut 2 is concordant with the outer top 16 in oil drum hole 6, the inner end surface 9 of built-in nut 2 is arranged in oil drum hole 6, and at the inner place in oil drum hole, the 4th stepped hole 15 is set, the internal diameter of the 4th stepped hole 15 is less than the external diameter of inner step 10, and the hole shoulder of the 4th stepped hole is fixedly connected with the inner end surface 9 of built-in nut.Adopt this structure, by the hole shoulder of the 4th stepped hole, the inner end surface 9 of built-in nut is protected and supported, further increase the anchoring strength between built-in nut and bung.
Two or more oil drum holes 6 can be set on oil drum cap.
Bolt can be the bolt of standard shape as shown in Figure 3, but also special shaped screw bolt 4 as shown in Figure 2, and the nut of special shaped screw bolt 4 is U-shaped cups of sealed bottom.
Certainly, thickening part 1 can all be positioned at the inner side of oil drum, also can all be positioned at the outside of oil drum, also can some be positioned at the inner side of oil drum, and another part is positioned at the outside of oil drum.Preferably thickening part 1 is positioned at the inside and outside both sides of oil drum.
In preferred embodiment, a part of in the axial direction inner side that is positioned at oil drum of built-in nut, a part is positioned at the outside of oil drum.Arranging like this, is also in order to improve the fastness between built-in nut and bung, increases sealing effectiveness, prevents leakage of oil.
Preferably, between built-in nut 2 and thickening part 1, be fixedly connected with by rotation molding.
