[0034] The overall stability of the oil delivery pipe 1 is adaptively adjusted by setting the windshield 2 so that it can be stably straight. Then, when the subsequent aircraft needs to refuel, since the connecting pipe 9 has a telescopic function, a hard material will be used, and the docking ring 12 will slide to the right position of the connecting pipe 9 under the guidance of the positioning rod 10 under the forward wind pressure. At this time, the head of the whole connecting pipe 9 can be exposed to the driver's line of sight. The embedded ring 17 is convenient for the driver to slide the embedded ring 17 directly into the outer wall of the oil delivery pipe 1, and the power output of the motor 4 is turned on. The mounting ring 8 is driven to rotate, so that the threaded ring 16 gradually penetrates into the outer wall of the oil delivery pipe 1 through the threaded connection, and the sealing ring 17 and the sealing ring 2 18 are fitted to maintain the sealing during the oil delivery process.

[0035] The sealing ring 18 is slidably connected to the outer wall of the sealing ring 1 7, and the embedded ring 17 is slidably connected to the outer wall of the oil delivery pipe 1. When the sealing ring is threadedly brought into the two sealing rings 18, the sealing connection can be completed.

[0036] The gear 5 is meshed with the mounting ring 8, and the mounting ring 8 is threadedly connected to the outer wall of the threaded ring 16. The meshing connection between the gear 5 and the mounting ring 8 is to help the motor 4 output transmission, and through the rotation of the mounting ring 8, a threaded connection is made between the threaded ring 16, and the connecting pipe 9 can be connected to the oil delivery pipe 1 along the threaded connection.

[0037] The track block 13 is slidably connected to the outer wall of the positioning rod 10, and the positioning rod 10 is used to limit the sliding of the track block 13. The sealing ring 18 and the sealing ring 1 7 are both made of rubber material.

When releasing, the output direction of the motor 4 is adjusted in the reverse direction, and the disengagement can be achieved after the sealing ring 2 18 and the sealing ring 1 7 are disengaged.

[0040] The electromagnetic block 6 is slidably connected to the inner wall of the card slot 15, and the inner wall of the card slot 15 is made of iron, which is convenient for the electromagnet to adsorb and fit.

[0041] Working principle: When using the present aerial refueling oil pipe fixing device, after the refueling machine releases the oil delivery pipe 1, the overall stability of the oil delivery pipe 1 is first adaptively adjusted through the setting of the windshield 2, so that it can be stably straight. Then, when the subsequent aircraft needs to refuel, since the connecting pipe 9 has a telescopic function, a hard material will be used, and the docking ring 1 will slide to the right position of the connecting pipe 9 under the guidance of the positioning rod 10 under the forward wind pressure. At this time, the head of the entire connecting pipe 9 can be exposed to the driver's line of sight. The embedded ring 17 is convenient for the driver to slide the embedded ring 17 directly into the outer wall of the oil delivery pipe 1, and the power output is turned on by the motor 4. The mounting ring 8 is driven to rotate, so that the threaded ring 1 gradually penetrates into the outer wall of the oil delivery pipe 1 through the threaded connection, and the sealing ring 1 7 and the sealing ring 2 18 are fitted to maintain the sealing during the oil delivery process.

[0042] When the connection is completed, with the wind shield 2 as the wind direction guide and under the push of the spring 11, the docking ring 12 will come into contact with the wind shield, and through the connection between the energized electromagnetic block 6 and the card slot 15, the position of the docking ring 12 is fixed. When releasing, the output direction of the motor 4 is adjusted in the reverse direction, and the disengagement can be achieved after the sealing ring 2 18 and the sealing ring 1 7 are disengaged.
