A shock-absorbing ball 16 is sleeved on the top of the spherical seat 15. The top of the shock-absorbing ball 16 is fixedly connected to the bottom of the connecting plate 9. Shock-absorbing pads 11 are fixedly connected to both sides of the bottom of the mounting seat 10. A spherical sleeve 17 is sleeved at the socket of the spherical seat 15 and the shock-absorbing ball 16. Damping spring columns 12 are fixedly connected to the four corners of the bottom of the connecting plate 9. The bottom of the damping spring columns 12 is fixedly connected to the bottom end of the bottom groove 6. Telescopic rods 25 are fixedly connected to the four corners of the top of the fixed substrate 13. The top of the telescopic rods 25 is fixedly connected to the bottom of the connecting plate 9. By installing the fuel tank outer shell 2 on the top of the shock-absorbing assembly 1, when the fuel tank outer shell 2 vibrates during operation, it drives the swing of the mounting seat 10. When the mounting seat 10 swings, it is buffered by the shock-absorbing pads 11, and part of the vibration force is transmitted to the connecting plate 9. The elastic potential energy of the damping spring columns 12 and the telescopic rods 25 at the bottom of the connecting plate 9 is used for secondary buffering, thereby improving the seismic performance of the fuel tank outer shell 2. The bottom of the connecting plate 9 is supported by the shock-absorbing ball 16 and the spherical seat 15, increasing the bearing capacity of the connecting plate 9 to support the fuel tank outer shell 2.

At this time, the elastic potential energy of the first C-shaped elastic piece 22, the second C-shaped elastic piece 23 and the shock-absorbing rubber balls 24 is used to enhance the anti-impact performance of the anti-impact plate 21, indirectly increasing the explosion-proof performance of the fuel tank outer shell 2.

[0025] During specific use, the fuel tank outer shell 2 is installed in the inner cavity of the fitting groove 27 through the threaded holes 18 and the locking bolts 26. When the fuel tank outer shell 2 vibrates during operation, it drives the swing of the mounting seat 10. When the mounting seat 10 swings, it is buffered by the shock pads 11, and part of the vibration force is transmitted to the connecting plate 9. The elastic potential energy of the damping spring columns 12 and the telescopic rods 25 at the bottom of the connecting plate 9 is used for secondary buffering, thereby improving the seismic performance of the fuel tank outer shell 2.

At this time, the elastic potential energy of the first C-shaped elastic piece 22, the second C-shaped elastic piece 23, and the shock-absorbing rubber balls 24 is used to enhance the impact resistance of the impact-resistant plates 21, indirectly increasing the explosion-proof performance of the fuel tank outer shell 2.
