The present invention relates to a box-shaped steel packaging box, and more specifically, to rotate the steel member, the coupling protrusion, the reinforcement plate, the shape of the clamp differently from the prior art, and to securely stack the rotating steel packaging It's about the box.

As is well known, with the rapid development of science and technology along with the development of the industrial society, the mass production of goods by factory automation has become commonplace, and thus the cargo volume has increased rapidly, resulting in warehouse and logistics automation. In response to this phenomenon, various industrial sites manufacture and use various packing boxes in order to transport large quantities of cargo more quickly.

That is, the packing box is used to load and conveniently transport the cargo, the packing box is a flat plate-shaped flat to move the loadable cargo in layers, such as refractory and grain, in addition to the steel packing box for loading the steel coil There are a wide variety of uses and shapes of packaging boxes, such as packaging boxes, and box-shaped packaging boxes having an open top for carrying and moving a difficult-to-load or moving object in layers.

Among them, the box-shaped packing box is used to make the four sides of the box firmly to load heavy cargo or floating cargo and to prevent damage of the loaded cargo. Can be.

However, in the conventional packaging box, when assembling as necessary, nails are fixed between each frame, or the packaging box is completed using fastening means using bolt nuts, which is complicated and takes a lot of time. . In addition, since only a packing box takes up a lot of volume, it is difficult to reuse the collection box because the transportation cost is too high to collect only the empty packing box after the delivery of the cargo is completed. It is decomposed to reduce, which is mostly broken in the decomposition process and consumes a lot of time.

In order to solve this problem, a folding packaging box can be used to fold the side, but the folding packaging box is simply used by using only a hinge or by combining a small pin with a predetermined folding member, so that the folding is repeated. Fatigue accumulates in the hinges and pins, which increases the possibility of breakage, and there is a disadvantage in that the maintenance cost is increased due to the replacement of the broken hinges and pins. Furthermore, when the hinges and pins are broken during cargo transportation, the packing box There is a concern that the car will collapse and damage the cargo.

In addition, the packaging box does not have a separate support means for supporting the beams are combined even when assembling the four sides, the coupling force between the beams are not sufficient enough that the beam itself is very deformed when the packaging boxes are stacked. It can be seen, and also in the case of the combination of the beams to make the packaging box, because there is no special structure, it is inconvenient to combine.

In addition, even in the case of the clamp used in the four corners of the packaging box to use only the pin also in the coupling of the clamp and the auxiliary plate bar, it is difficult to see that the sufficient coupling force, and the case of the above-described hinge and pin Similarly, there was a problem that there is a fear of increasing the accumulation of fatigue and damage caused by repeated use.

The present invention is devised to solve the problems of the prior art as described above, an object of the present invention, the folding member of the folding box according to the repeated use by configuring the folding portion of the packaging box in the folding iron packaging box. It is to provide a rotating iron packing box that lowers the risk of damage and stably folds the front part (including both the front and back) and the side part (including both the left and right sides).

Another object of the present invention is to provide a coupling protrusion at the bottom to facilitate the coupling of the front portion and the bottom portion, and to more firmly support the combined beams of the front portion and the bottom portion and the beam To provide a rotary iron packaging box having a reinforcing plate that can act as a guide for the convenience of the combination when combined.
