Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a fuel dispenser calibration device with a leak-proof sealing joint, comprising a fixed plate 1, a fixed seat 2 fixedly connected to the upper surface of the fixed plate 1, a computer 3 fixedly connected to the upper surface of the fixed seat 2, one end of a connecting wire 4 fixedly connected to the input end of the computer 3, a funnel 5 fixedly connected to the other end of the connecting wire 4, the lower surface of the funnel 5 fixedly connected to the upper surface of the fixed plate 1, one end of an oil delivery pipe 6 fixedly connected to the outer wall of the funnel 5, a second funnel 7 fixedly connected to the other end of the oil delivery pipe 6, and a clamping assembly provided on the upper surface of the fixed plate 1.

[0019] Specifically, the fixing plate 1 fixes the fixing seat 2, ensuring that the fixing seat 2 is securely installed on the upper surface of the fixing plate 1 and maintains a stable position. The fixing seat 2 fixes and supports the computer 3, ensuring that the computer 3 is securely installed on the upper surface of the fixing seat 2 and remains stable during the detection process. The computer 3 fixes the connecting cable 4, enabling the transmission of electrical signals between the input terminal of the computer 3 and the external detection device. The funnel 1 5 fixes the connecting cable 4, protecting the signal transmission line and preventing it from shaking when fuel flows in. The fixing plate 1 fixes the funnel 1 5, ensuring that the funnel 1 5 is securely installed on the upper surface of the fixing plate 1 and ensuring a stable fuel flow path.

The funnel 2 7 fixes the other end of the fuel supply pipe 6, ensuring that fuel is smoothly introduced from the funnel 2 7 into the fuel supply pipe 6 and preventing fuel leakage.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The clamping assembly includes a support block 8, the lower surface of which is fixedly connected to the upper surface of the fixing plate 1. A slide 9 is fixedly connected to the upper surface of the support block 8. A threaded rod 10 is rotatably connected inside the slide 9. A handle 11 is fixedly connected to the outer end of the threaded rod 10. A slider 12 is threadedly connected to the outer wall of the threaded rod 10. The outer wall of the slider 12 is slidably connected to the inner wall of the slide 9. A clamping block 13 is fixedly connected to the outer wall of the slider 12. An oil filling pipe 14 is attached to the outer wall of the clamping block 13. An oil gun 23 is fixedly connected to the outer end of the oil filling pipe 14. The outer wall of the oil gun 23 is slidably connected to the inner wall of the funnel 2 7.

[0021] Specifically, the support block 8 serves to fix and support the slide 9, ensuring that the slide 9 is securely mounted on the upper surface of the support block 8 and remains stable during operation. The slide 9 serves to limit and support the threaded rod 10, ensuring that the threaded rod 10 can rotate stably inside the slide 9 without wobbling. The handle 11 drives the threaded rod 10, causing it to rotate along the inside of the slide 9 when the handle 11 is manually turned. The threaded rod 10 transmits power to the slider 12, causing it to slide along the inner wall of the slide 9 when the threaded rod 10 rotates. The slide 9 also transmits power to the slider 12. 2 serves as a limit, ensuring that the slider 12 does not deviate when moving on the inner wall of the slide 9. The slider 12 drives the clamping block 13 to move synchronously when the slider 12 moves. The clamping block 13 fixes the refueling pipe 14, securing it firmly during the calibration process to prevent shaking or falling off. The refueling pipe 14 connects to and transports the fuel nozzle 23, ensuring that fuel can be smoothly delivered from the refueling pipe 14 to the fuel nozzle 23. The funnel 2 7 limits the fuel nozzle 23, ensuring that fuel is accurately introduced into the funnel 2 7 during refueling operations and preventing dripping.

[0022] Reference Figure 1 , Figure 2 and Figure 4 The output end of funnel 15 is fixedly connected to a leak-proof connector 15. The outer end of the leak-proof connector 15 is fixedly connected to a connecting pipe 16. The outer wall of the connecting pipe 16 is fixedly connected to a fixing block 18. The outer wall of the connecting pipe 16 is fixedly connected to a motor 17. The output end of the motor 17 is fixedly connected to a rotating shaft 19. The outer wall of the rotating shaft 19 is rotatably connected to the inside of the fixing block 18. The outer wall of the rotating shaft 19 is fixedly connected to a gear 20. The tooth end of the gear 20 is meshed with a gear 21. The inner wall of the gear 21 is fixedly connected to a movable pipe 22. The outer wall of the movable pipe 22 is rotatably connected to the inner wall of the connecting pipe 16.

[0023] Specifically, funnel 5 serves to fix the leak-proof connector 15, ensuring that the leak-proof connector 15 is securely installed at the output end of funnel 5 and maintaining the seal of the fuel flow channel. The leak-proof connector 15 serves to connect and seal the connecting pipe 16, achieving a sealed connection between funnel 5 and connecting pipe 16 to prevent fuel leakage. Connecting pipe 16 serves to fix the motor 17, ensuring that the motor 17 is securely installed on the outer wall of connecting pipe 16 and maintains a stable position during operation. Motor 17 drives the rotating shaft 19, causing the rotating shaft 19 to rotate along the interior of the fixing block 18 when the output end of motor 17 rotates. The fixed block 18 supports and limits the rotating shaft 19, ensuring that the rotating shaft 19 can rotate smoothly inside the fixed block 18. The rotating shaft 19 drives the gear 20 to rotate when the rotating shaft 19 rotates. The gear 20 drives the gear 21 to rotate synchronously through tooth end meshing. The gear 21 drives the movable tube 22 to rotate when the gear 21 rotates. The connecting tube 16 limits and supports the movable tube 22, ensuring that the movable tube 22 remains stable during rotation.

[0024] Working principle: When fixing the refueling pipe 14, first turn the handle 11. The rotation of the handle 11 drives the threaded rod 10 to rotate along the inside of the slide 9. The rotation of the threaded rod 10 drives the slider 12 to slide along the inner wall of the slide 9. The movement of the slider 12 further drives the clamping block 13 to move synchronously. The movement of the slider 12 achieves the clamping and fixing of the refueling pipe 14, thus achieving the effect of fixing the refueling pipe 14. This solves the problem that the refueling pipe 14 is prone to shaking during the calibration process, which affects the accuracy of the refueling volume detection. It is beneficial to improve the stability and accuracy of the calibration data. When the angle of the movable tube 22 needs to be adjusted, the motor 17 is started first. The output end of the motor 17 rotates, which drives the rotating shaft 19 to rotate along the inside of the fixed block 18. The rotation of the rotating shaft 19 drives the gear 20 to rotate. The tooth end of the gear 20 meshes with the tooth end of the gear 21. The rotation of the gear 20 drives the gear 21 to rotate. The rotation of the gear 21 drives the movable tube 22 to rotate synchronously along the inner wall of the connecting tube 16. The angle of the movable tube 22 is adjusted by the rotation of the movable tube 22. This achieves the effect of adjusting the angle of the movable tube 22, which is conducive to flexibly adjusting the refueling direction according to different verification requirements, thereby improving the adaptability and ease of use of the fuel dispenser verification device. In actual use, the fuel dispenser calibration device with anti-drip sealing joint can not only fix the fuel pipe 14, but also adjust the angle of the movable pipe 22.
