Detailed Description

The utility model is described in detail with the accompanying drawings, as shown in the figures, the utility model comprises a box body and a box cover, the plane expansion structure of the box body comprises a bottom plate 1, and the upper and lower sides of the bottom plate are both connected with an end plate 2; the left end and the right end of the bottom plate are both connected with the side plate 3; the outer side of the side plate 3 is connected with an inner side plate 31, the outer side of the inner side plate is connected with a flap 32, and the inner side plate and the flap are provided with a communicating groove 34; the outer side of the end plate 2 is connected with an inner end plate 21, and the outer side of the inner end plate 21 is connected with an end plate flap 22;

the two sides of the inner side plate 21 are connected with the buffer sheet 4; the buffer sheet 4 is provided with a limiting groove 41, and after a three-dimensional structure is formed, the periphery of the workpiece 10 is abutted against the limiting groove; the bottom plate is provided with a folding support plate 6 which is rectangular, and one side of the folding support plate is connected with the bottom plate; the folding support plate is fixed with the bottom plate by bypassing the lock hole 61;

the box cover comprises a cover plate 7, a cover plate end plate 8 and a cover plate side plate 9; the cover plate is also provided with a folding support plate 6 and a lock hole 61.

In order to increase the strength, a web 5 is arranged between the side plate and the end plate.

The three-dimensional structure of the box body is as follows: the inner end plate 21 is turned 180 degrees and attached to the end plate 2, and the end plate flap 22 is attached to the bottom plate; the buffer sheet 4 is turned 90 degrees along the crease 42 and is vertical to the inner end plate 21; after the inner side plate 21 is turned by 180 degrees and attached to the side plate 2, the side plate 2 is turned by 90 degrees and is vertical to the bottom plate 1; the cushion flap 46 is inserted between the inner side plate and the side plate;
