s2: because the density of the water is higher than that of the ice, when the water in the second water bag (45) is frozen into the ice, the volume of the second water bag (45) is increased, namely the ice in the second water bag (45) pushes the second arc (47) outwards;
s3: the second reinforcing ribs (41c) are extruded, the radius of the second arc (47) under the extrusion action is increased, so that the third arc (48) is contracted towards the inner side, and meanwhile, the second reinforcing ribs (41c) start to pull the third arc (48) to move towards the first separating plate (42) due to the reduction of the radius, so that a one-degree gap is formed between the third arc (48) and the box body (1);
s4: when the object is conveyed to a designated place, due to the opening and closing of the box body (1) and the emission of cold air in the transportation process, ice in the first water bag (44) and the second water bag (45) in the refrigerating mechanism (4) begins to melt slowly, the volume of the second water bag (45) shrinks, the supporting effect of ice blocks is lost, and the third arc-shaped part (48) expands outwards gradually and is finally completely attached to the box body (1), so that the integral strength of the structure is improved when the whole packaging box is conveyed back, and the refrigerating mechanism (4) is prevented from falling.
