[0032] As shown in Figs. Figure 1 and Figure 5 As shown in Figs.
[0033] The inner wall of the oil inlet pipe 3 is fixedly connected with a convex ring 31, and the inner wall of the convex ring 31 is fixedly installed with a sealing gasket 32. The top end of the oil inlet pipe 3 is threadedly connected with a sealing cover 4. The bottom end of the sealing cover 4 is fixedly connected with an annular block 41. The outer surface of the annular block 41 is slidingly connected to the inner wall of the convex ring 31. The bottom end of the annular block 41 is wavy and in contact with the sealing gasket 32.
[0034] The bottom end of the cover plate of the sealing cover 4 is fixedly connected with a limiting plate 42, which is embedded in the top end slot of the oil inlet pipe 3.
[0035] Specifically, when the injection of lubricating oil is completed, first, the sealing cover 4 is aligned with the oil inlet pipe 3, and then the sealing cover 4 is rotated to connect with the oil inlet pipe 3. During the rotation process, the annular block 41 gradually moves downward and slides into the gap between the convex ring 31 and the oil inlet pipe 3. The wavy bottom end of the annular block 41 will extrude the sealing gasket 32. After being extruded, the sealing gasket 32 will be elastically deformed to fill the gap between the annular block 41, the convex ring 31 and the oil inlet pipe 3, thereby preventing the lubricating oil from leaking from the oil inlet pipe 3, so as to realize the sealing of the oil inlet pipe 3.
[0036] Meanwhile, the limiting plate 42 at the bottom end of the cover plate of the sealing cover 4 is gradually embedded in the top end notch of the oil inlet pipe 3, and the limiting plate 42 plays a role of positioning and secondary sealing, preventing further guarantee of the sealing effect at the oil inlet pipe 3 in the subsequent use process of the oil drum 1.
[0037] In a further embodiment, the inner wall of the pressure relief pipe 5 is fixedly connected with a nut seat 51, a through hole 52 is formed in the nut seat 51, the outer surface of the nut seat 51 is threadedly connected with a sleeve 6, the outer surface of the sleeve 6 is slidingly connected to the inner wall of the pressure relief pipe 5, a sealing ring 53 is fixedly installed above the nut seat 51, and the bottom end of the sleeve 6 is in contact with the surface of the sealing ring 53.
[0038] Specifically, on the one hand, after the sleeve 6 is tightened, the bottom end of the sleeve 6 is in close contact with the surface of the sealing ring 53, the sealing ring 53 is elastically deformed, the gap between the sleeve 6 and the nut seat 51 and the pressure relief pipe 5 is filled, and the leakage of lubricating oil from the pressure relief pipe 5 is prevented, and on the other hand, when a component needs to be replaced, it is more convenient to disassemble without the need for complex tools, thereby reducing labor intensity.
[0039] In a further embodiment, a through groove 61 is formed in the sleeve 6, a sliding groove 62 is formed above the through groove 61, air outlet holes 63 are formed on both sides of the inner wall of the sliding groove 62, and the through hole 52 is in communication with the through groove 61.
[0040] A base ring plate 64 is fixedly installed in the through groove 61, a spring 65 is fixedly connected to the top end of the base ring plate 64, a sliding block 66 is slidingly connected to the top end of the spring 65, and the sliding block 66 is slidingly connected to the inner wall of the sliding groove 62.
[0041] Specifically, when the internal pressure of the oil drum 1 rises, the pressure is transmitted to the through groove 61 in the sleeve 6 through the through hole 52 on the nut seat 51 in the pressure relief pipe 5, and when the internal pressure of the oil drum 1 is greater than the elastic force of the spring 65, the pressure pushes the sliding block 66 to slide upward against the elastic force of the spring 65. As the sliding block 66 slides upward, the air outlet holes 63 on both sides of the inner wall of the sliding groove 62, which were originally closed by the sliding block 66, are gradually opened. At this time, the high-pressure gas in the oil drum 1 can enter the through groove 61 through the through hole 52 and then be discharged to the outside through the opened air outlet holes 63, thereby realizing the release of the excessively high pressure in the oil drum 1 and reducing the internal pressure of the oil drum 1. When the internal pressure of the oil drum 1 decreases to a certain extent, the elastic force of the spring 65 is greater than the force of the remaining pressure in the oil drum 1 acting on the sliding block 66, and the spring 65 pushes the sliding block 66 to slide downward. The sliding block 66 re-closes the air outlet holes 63, preventing external air from entering the oil drum 1, so that the oil drum 1 is again restored to a relatively sealed state.
[0042] In a further embodiment, the two sides of the sealing cover 4 are fixedly connected with fixed seats 43, and handles 44 are slidingly connected to the inner walls of the fixed seats 43.
[0043] Specifically, when the sealing cover 4 needs to be unscrewed, first hold the two handles 44 and pull upward, when pulled to a position parallel to the top end of the sealing cover 4, the handle 44 is in an ideal position for force turning, which can make the user better exert force when subsequently turning the sealing cover 4, and use the principle of leverage to make the operation of turning the sealing cover 4 more labor-saving.
[0044] In further embodiments, the oil drum 1 is fixedly installed with a side wall reinforcing rib 11 on the side wall, and a bottom wall reinforcing rib 12 on the bottom wall, and the bottom end of the side wall reinforcing rib 11 is connected to the top end of the edge of the bottom wall reinforcing rib 12.
[0045] Specifically, the side wall reinforcing rib 11 increases the strength and rigidity of the side wall of the oil drum 1, so that it can better maintain its shape when subjected to external pressure, collision or internal oil pressure changes, preventing the side wall from deforming or breaking, thereby avoiding leakage of lubricating oil, and the bottom wall reinforcing rib 12 enhances the load-bearing capacity of the bottom of the oil drum 1, so that when the oil drum 1 is placed, it can better disperse the pressure on the bottom from the weight of the oil drum 1 itself and the internal lubricating oil, preventing the bottom from being damaged due to uneven stress.
[0046] It should be understood that the use of these embodiments is only for the purpose of illustrating the present application and is not intended to limit the scope of protection of the present application. In addition, it should also be understood that after reading the technical content of the present application, those skilled in the art can make various modifications, modifications and / or variations to the present application, and all these equivalent forms also fall within the protection scope defined by the appended claims of the present application.
