Based on foretell side open folding container, its theory of operation does:

(1) when the side door is opened, the door lock rod is opened, and the side door 8 is pulled by two hands, so that the side door plate 8.1 and the rest side columns 8.2 are folded from two sides to the side column (II), as shown in fig. 3, until the side door 8 is completely folded like a folding fan, and the opening of the side door 8 is realized. When the side door 8 is closed, the side door 8 is completely unfolded, and each door lock rod is locked, so that the side door 8 is closed. The container is of a central symmetry structure, when the side door 8 is opened, the two side doors 8 are not just opposite (the side columns (two) of the side doors 8 on the two sides of the container are arranged in a staggered manner), so that goods at the position shielded by the side doors 8 can be loaded from the opposite side, and the full side opening of the side doors 8 is realized.

(2) As shown in fig. 7 and 8, when folding, the door lock lever is opened, and then the box top 1 is lifted by a crane or other auxiliary machine tool, so that the end wall 6 and the side door 8 are released from the restraint of the box top 1. And (3) turning over the side door panel (VII) and the side door panel (VIII) by hand to drive hinges at two ends of the side column (VI) to rotate, so that the side column (VI) rotates around the center of the hinge shaft connected with the side door panel (VI), and drives the side door panel (VII), the side column (VII) and the side door panel (VIII) to turn over for 180 degrees, thereby completing the first action shown in the figure 4. And turning over the side door panel (six) or the side door panel (seven) to drive the hinges at the two ends of the side column (four) to rotate, so that the side column (four) rotates around the center of the hinge shaft connected with the side door panel (four), and drives the side door panel (five), the side column (five), the side door panel (six), the side door panel (seven), the side column (seven) and the side door panel (eight) to be turned over for 180 degrees, thereby completing the action two shown in figure 5.

The side door 8 is pushed and a door lock rod is held by hand, so that the side door 8 after being folded is slowly turned inwards by 90 degrees around a hinge shaft connected with the bottom 10 of the side column (II), and the side door 8 on the other side is also folded by the same operation, as shown in fig. 9. The folding upright posts 6.1 in the end wall 6 are turned over, so that the end wall plate 6.2 and the folding upright posts 6.1 are turned inwards by 90 degrees around the hinge axis of the end wall 6. Finally, the suspended box top 1 is lowered by using a crane or other equipment, and the upper upright 4 is inserted into the corresponding lower upright 6.3, thereby completing the folding operation of the container, as shown in fig. 10 and 11.

As shown in fig. 6, since the folding mode of the side doors 8 is to fold towards the middle quarter, after the side doors 8 on the left and right sides complete the second action, the total length of the side doors 8 accounts for one half of the length of the container, and since the side doors 8 on the left and right sides respectively account for one half and are in a staggered state after being folded, the left and right side doors 8 do not interfere with each other when being folded inwards, which is different from the folding mode of the traditional folding door towards two sides or one side, and the folding mode of the side doors 8 is novel.

(3) When the side door 8 is unfolded, the box top 1 is lifted by a crane or other auxiliary mechanical tools, the folded part of the end wall 6 is turned up, then the side door 8 is turned up, the side doors 8 are unfolded in sequence, and the side doors 8 are positioned by the side door 8 longitudinal positioning device 7. The lifted box top 1 is put down, the upper upright post 4 of the box top 1 is inserted into the corresponding folding upright post 6.1 of the end wall 6, and the side post (II) of the side door 8 is inserted into the corresponding position of the upper side beam 2. And locking the door lock rod to complete the unfolding operation of the container.
