[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown:

[0030] This utility model provides a diversion and equalization oil injection pipeline structure, including an oil filling pipe head 1 and a diversion structure 2;

[0031] The refueling nozzle 1 has an inlet 101. A limit ring 102 is fixedly connected to the outer side of the refueling nozzle 1. The bottom of the refueling nozzle 1 has a diversion structure 2, which includes a first variable diameter conical tube 201, an oil guide tube 202, an oil distribution basin 203, and an oil delivery tube 205. One end of the refueling nozzle 1 is fixedly connected to the first variable diameter conical tube 201, and the end of the first variable diameter conical tube 201 is fixedly connected to the oil guide tube 202. The bottom of the oil guide tube 202 has an oil distribution basin 203. An oil collection groove 2031 is opened inside the oil distribution basin 203. Oil distribution holes 204 are opened on both sides of the oil distribution basin 203. A second variable diameter conical tube 2041 is fixedly connected to the oil distribution hole 204. The end of the second variable diameter conical tube 2041 is fixedly connected to the oil distribution hole 204. An oil supply pipe 205 is fixedly connected to the oil supply pipe 205, and a connecting bend 2051 is fixedly connected to the end of the oil supply pipe 205. A connecting disc 2052 is fixedly connected to the bottom outer side of the connecting bend 2051. When injecting oil, the oil enters the first variable diameter conical pipe 201 through the filling pipe head 1, enters the oil guide pipe 202 through the first variable diameter conical pipe 201, and finally enters the oil distribution basin 203. Because it cannot be directly discharged, the oil will accumulate in the oil distribution basin 203 and rise horizontally. When the oil height exceeds the oil distribution hole 204, the oil will enter the second variable diameter conical pipes 2041 on both sides through the oil distribution hole 204, and finally enter the oil tank through the oil supply pipe 205 and the connecting bend 2051, thus completing the balanced oil distribution injection.

[0032] Example 2: Based on Example 1, wherein, as Figure 2 , Figure 3 and Figure 4 As shown, a sealing structure 3 is provided between the oil guide pipe 202 and the oil distribution basin 203. The sealing structure 3 includes a first annular groove 301 and a connecting inner ring 302. The first annular groove 301 is formed on the inner side wall of the bottom end of the oil guide pipe 202, and the connecting inner ring 302 is fixedly connected to the inner side wall of the oil distribution basin 203. A second annular groove 3021 is formed on the connecting inner ring 302. A sealing ring 303 is installed in the first annular groove 301 and the second annular groove 3021. A connecting collar 304 is fixedly connected to the outer side of the oil guide pipe 202. An assembly hole 3041 is formed on the connecting collar 304. A connecting lug 305 is fixedly connected to the outer side of the oil distribution basin 203. A threaded hole 3051 is formed on the connecting lug 305, and the threaded hole 3051 is aligned with the assembly hole 3041. A connecting ring 305 is installed in the assembly hole 3041. Connecting bolt 306 engages with threaded hole 3051. Six sets of mounting holes 3041, connecting lugs 305, and connecting bolts 306 are provided. The sealing ring 303 ensures the sealing between oil guide pipe 202 and oil distribution basin 203, preventing oil leakage. By rotating connecting bolt 306, it can be removed from threaded hole 3051, thus disconnecting oil guide pipe 202 from oil distribution basin 203. This allows for the replacement of different numbers of distribution pipes as needed. During installation, simply install sealing ring 303 into second annular groove 3021, then insert oil distribution basin 203 onto the outside of oil guide pipe 202, aligning mounting hole 3041 with threaded hole 3051. Finally, engage connecting bolt 306 to complete the connection.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In this invention, firstly, the sealing ring 303 is installed into the second annular groove 3021. Then, the oil distribution basin 203 is inserted into the outside of the oil guide pipe 202, aligning its mounting hole 3041 with the threaded hole 3051. Finally, the connecting bolt 306 is engaged to complete the connection. During oil filling, the oil enters the first reducing diameter conical pipe 201 through the filling pipe head 1, then enters the oil guide pipe 202, and finally enters the oil distribution basin 203. Because it cannot be directly discharged, the oil accumulates in the oil distribution basin 203. As the oil level rises, when the oil volume exceeds the oil distribution hole 204, the oil will then enter the second reducing diameter conical pipes 2041 on both sides through the oil distribution hole 204, and finally enter the oil tank through the oil delivery pipe 205 and the connecting bend 2051, thus completing the balanced oil distribution injection. This not only ensures the balanced distribution of oil volume during injection, but also buffers the pressure fluctuations during injection, reduces the damage to the pipeline caused by oil pressure shocks, and reduces the risk of pipeline leakage and rupture. This greatly improves the stability and reliability of the entire refueling system, reduces the frequency of maintenance, and saves on operation and maintenance costs.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
