[0026] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1 As shown, the oil and gas barrel in this embodiment includes a barrel body 10 and an oil level mirror 20 arranged on one side of the barrel body 10. An oil hole is opened on one side of the barrel body 10, and the connecting port 15 of the oil level mirror 20 is sealed and assembled with the outer wall of the barrel body 10.

[0028] like Figures 2 to 5 As shown, the oil level mirror in this embodiment includes a mirror body shell 1, a glass tube 2, a bolt 6, a plug 5 and a float 3.

[0029] The scope housing 1 has an axial passage 12 along its length and an observation window 11 on its side. Connection ports 15 are formed at both ends of the scope housing 1, which communicate with the axial passage 12. The scope housing 1 is made of metal, in this embodiment, aluminum alloy. The axial passage 12 extends through the scope housing 1, and plugs 5 are provided at both ends to seal the passage.

[0030] The mirror housing 1 in this embodiment is symmetrically designed at both ends. Each end of the mirror housing 1 has a transverse channel 13, with one end of each transverse channel 13 forming a connection port 15. Each transverse channel 13 is provided with a bolt 6, which has an oil passageway 62. The oil passageway 62 forms a first oil port 621 on the side of the bolt 6 that communicates with the glass tube 2, and a second oil port 622 at the end of the bolt 6 that communicates with the oil and gas tank.

[0031] The glass tube 2 is sealed in the axial channel 12 , and the glass tube 2 is arranged facing the observation window 11 .

[0032] Axial channel 12 is formed with annular grooves 14 at both ends of glass tube 2. Sealing rings 21 are embedded in annular grooves 14, through which glass tube 2 passes. In this embodiment, there are two annular grooves 14 spaced apart, and each annular groove 14 has a sealing ring 21 embedded therein.

[0033] A float 3 that can display the oil level is provided in the glass tube 2. The float color is preferably colorful so that it can be observed visually.

[0034] A stopper 4 is provided at each end of the glass tube 2. Each stopper 4 has an inner hole whose diameter is smaller than that of the float 3. This ensures that the float remains within the glass tube. A retaining spring 41 is provided within the axial passage 12 near the stopper 4 to secure it in place.

[0035] The end of the bolt 6 extends out of the connection port 15 of the scope housing 1. A sealing ring 72 is sleeved over the end of the bolt 6, which is tightly attached to the outer wall of the scope housing 1. A combined gasket 71 is provided between the bolt head and the scope housing to provide a position limit. The combined gasket 71 is made of a composite metal gasket and rubber.

[0036] During assembly, the sealing ring 21 is first placed in the annular groove 14 using a tool, and then the glass tube is inserted into the axial channel 12 and passes through the sealing ring 21. Then, the limit gaskets and clamping rings are installed at both ends, and then the plugs and bolts are installed.

[0037] The metal shell of the mirror body improves its strength. At the same time, the mirror body shell is only opened in the middle to form an observation window, and both ends are intact and can withstand greater pressure, so the whole is not easy to break; annular sealing rings are used at both ends of the assembly of the axial channel of the glass tube and the mirror body shell, which can effectively achieve a sealing effect, avoid oil leakage between the hard connection between the glass tube and the mirror body shell, and ensure long-term and stable operation.
