[0040] Refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 5 , A universal wheel is fixedly connected to the bottom of the fixed shell 5. A sealing ring 9 is slidably connected inside the sealing door 1. A plurality of oil outlet holes 12 are opened on the outside of the flow guide pipe 13. The fixed shell 5 is used to carry the metal tank 3. The universal wheel is used to move the device. The sealing ring 9 is used to ensure the airtightness between the cover plate 10 and the sealing door 1.

[0041] Refer to Figure 1 - Figure 4 , An oil outlet pipe 6 is fixedly connected to the bottom of the metal tank 3. A valve 8 is fixedly connected to the outside of the oil outlet pipe 6. The metal tank 3 is used to store oil. The oil outlet pipe 6 is used for oil outlet. The valve 8 is used to control the opening and closing of the oil outlet pipe 6.

[0042] Refer to Figure 8 and Figure 9, One end of the spring 26 is fixedly connected to one side of the backing plate 25, and the other end of the spring 26 abuts against the inner wall of the outer shell 29. The outer side of the backing plate 25 is slidably connected inside the outer shell 29. The spring 26 is used to firmly insert the bolt 24 into the diversion pipe 13 without external force.

The pull rod 28 is used to fix the bolt 24 after pulling it out. The L-shaped groove 7 and the arc-shaped groove 11 provide a movement track for the pull rod 28.

[0044] Working principle: The oil inlet 2 is sealed by the bottom cover plate 10. There is a sealing ring 9 on the cover plate 10. When the fuel gun is inserted into the oil inlet 2, due to the action of force, the cover plate 10 will be opened downward. The bottom of the cover plate 10 is fixed to the first connecting plate 19. The second connecting plate 22 is fixed to the bottom of the sealing door 1. The first connecting plate 19 and the second connecting plate 22 are connected by a connecting column 20. The first connecting plate 19 is rotatably connected to the connecting column 20, and the second connecting plate 22 is fixedly connected to the connecting column 20. Then insert the fuel gun into the inside of the diversion pipe 13. There is a filter screen 18 inside the diversion pipe 13. There are multiple oil outlet holes 12 on the outer side of the diversion pipe 13. The diversion pipe 13 is fixed to the inner wall of the metal tank 3 by a hollow ring 16 and a fixing rod 14. A second temperature sensor 17 is fixed to the inner wall of the diversion pipe 13 close to the fuel gun, and a first temperature sensor 15 is fixed to the inner wall of the metal tank 3. The metal tank 3 is fixed inside the fixed shell 5. There is a temperature display on the fixed shell 5. The upper screen displays the temperature transmitted by the first temperature sensor 15, and the lower screen displays the temperature transmitted by the second temperature sensor 17. An oil outlet pipe 6 is fixed to the bottom of the metal tank 3. A valve 8 is fixed on the oil outlet pipe 6. Multiple universal wheels are fixed to the bottom of the fixed shell 5, which realizes that when the staff refuels the metal tank 3, there is no need to hold the fuel gun for a long time and the temperature can be measured automatically in real time, improving work efficiency. When it is necessary to replace or clean the diversion pipe 13, by pulling the pull ring, the pull ring drives the bolt 24 to slide inside the outer shell 29, and the backing plate 25 fixed to the outside of the bolt 24 also slides inside the outer shell 29, thereby compressing the spring 26. The pull rod 28 is fixed to the outside of the backing plate 25. When the bolt 24 is pulled out of the diversion pipe 13, by rotating the bolt 24, the pull rod 28 is stuck in the L-shaped groove 7. When the replacement is completed, rotate the bolt 24 to a suitable position so that the pull rod 28 can slide in the L-shaped groove 7, and then under the action of the spring 26, the bolt 24 is inserted into the diversion pipe 13 again, which facilitates the staff to clean or replace the diversion pipe 13.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
