Abstract
The utility model provides a sealing oil drum. In order to overcome the defect that an existing oil drum is poor in sealing performance, the sealing oil drum is good in sealing performance. The sealing oil drum comprises a drum cover. At least one thickening portion is arranged on the drum cover. An oil drum hole is formed in the thickening portion. An internally-installed nut is fixedly arranged inside the oil drum hole. A bolt is connected with the internally-installed nut. A sealing ring is arranged between the internally-installed nut and the bolt. According to the oil drum with the structure, due to the facts that the thickening portion is arranged on the drum cover, the oil drum hole is formed in the thickening portion, and the internally-installed nut is fixedly arranged inside the oil drum hole, the length of connecting threads on the oil drum hole is increased, and the sealing effect is effectively improved.
Description
Technical field
The utility model relates to a kind of oil drum, particularly relates 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 utility model patent of oil drum sealing arrangement, staving place at hydraulic fluid port is provided with negative thread, in the time of need to sealing oil drum, 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.
Utility model content
The purpose of this utility model is the deficiency for prior art oil drum poor sealing performance, and the valued knife sealing oil drum that a kind of sealing property is good is provided.
The purpose of this utility model is achieved through the following technical solutions:
A sealing oil drum, comprises bung, is provided with at least one thickening part on described bung, and in thickening part, place is provided with oil drum hole, 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 inside 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.
The oil drum that adopts the utility model structure, 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.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model will be further described:
As shown in Figure 1, 2, the sealing oil drum of the utility model embodiment, 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, at bolt 4 and 2 of built-in nuts, 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 built-in nut 2 and 1 of the thickening part firmness being connected, and 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 the place, the inner in oil drum hole arranges the 4th stepped hole 15, 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.
