One side of the shift block 19 contacts the side of the mounting shell 18 away from the reinforcement frame 13. A movable rod 110 is provided inside the mounting shell 18. A return spring 111 is provided outside the movable rod 110. A clamping block 112 is provided on the end of the movable rod 110 away from the shift block 19.

It is mentioned here that the material of the thermal insulation layer 21 is polystyrene foam, which is lightweight, water-resistant and has good thermal insulation properties, effectively isolates heat transfer, and will not be corroded by water. In addition, an elastic strip 22 is provided between the inner wall of the metal hose shell 11 and the outside of the thermal insulation layer 21, which can effectively absorb and alleviate the impact and vibration caused by earthquakes or other vibrations, thereby extending the service life of the thermal insulation layer 21.
[0028] The utility model provides a seismic-resistant metal hose for a storage tank, and the specific working principle is as follows:
[0029] When the staff needs to install the storage tank and the earthquake-resistant metal hose, they first need to sequentially move the shift block 19 provided on the outside of the reinforcement frame 13, and then one side of the shift block 19 will produce friction and extrusion with the outside of the installation shell 18, and this friction force will push the movable rod 110 and the block 112 to move in the direction of the shift block 19. In this process, the return spring 111 will be squeezed by the block 112, and then deformed and contracted. The block 112 will sink into the interior of the installation shell 18 in this process. Next, the staff will put the hose flange 12 at one end of the metal hose shell 11 It is docked with the flange of the tank mouth, and the bolts 14 are passed through the threaded grooves provided in the reinforcement frame 13, the hose flange 12 and the tank mouth flange 32 to fix them together, and the nut 16 is threadedly connected to the bolt 14 protruding on one side of the tank mouth flange 32. In this way, the connection between the tank mouth flange 32 and the hose flange 12 can be fixed and clamped. Finally, by lowering the shift block 19, the return spring 111 will lose the extrusion force and release the elastic force to push the clamping block 112 through the positioning hole 17 to be clamped in the reinforcement hole 15, so that the bolt 14 and the reinforcement frame 13 will be limited.
