Sea container

The utility model relates to a shipping container, wherein a plurality of boxes are orderly stacked from top to bottom, a plurality of vertically telescopic jacking blocks are symmetrically and uniformly distributed at the bottoms of the boxes, grooves are correspondingly formed in the tops of the boxes, the jacking blocks at the bottoms of the upper boxes can be inserted into the grooves at the tops of adjacent lower boxes, each jacking block comprises a convex groove cavity with a downward opening, a first spring and a vertical convex rod, the first spring is arranged in the convex groove cavity in a telescopic manner along the vertical direction, the upper ends of the convex rods extend into the convex groove cavity and are abutted to the bottoms of the first springs, and the lower ends of the convex rods vertically extend out and are arranged to be expansion ends. Through be provided with recess and kicking block respectively at the top and the bottom of the container body, when the container stacks like this, the kicking block of top container bottom just can stretch into in the recess at below container top, has increased the even atress of arranging the container from top to bottom, when receiving external force, the container of stacking from top to bottom is an integer, and the container of stable connection distributes the power, is difficult for the slope.
