N-butane cooling storage tank

The utility model relates to the technical field of n-butane storage tanks, in particular to an n-butane cooling storage tank which comprises a bottom plate, vertical plates are symmetrically and fixedly installed on the two sides of the top of the bottom plate, buffering protection mechanisms are movably installed at the left end and the right end of the bottom plate, and a transverse plate is fixedly installed on the tops of the two vertical plates. By means of the structural design that the holding mechanism is installed, the connecting block on the moving block is driven by the air cylinder to move, the clamping block is further driven to move left and right on the limiting rod, and therefore when the storage tank is held and clamped through the clamping block in the transportation process, the storage tank is clamped through the clamping block; inclination and shaking of the storage tank in the transportation process are reduced, the stability of the storage tank can be kept, the risk of overturning and
