When the foldable container is folded, the side panel 3 is turned inside the foldable container, the folded portion 312 and the folded portion 311 are folded in half, and the stacking height of the folded portion 312 and the folded portion 311 after folding in half is D₂. And then the side plate 1 is upwards slid in the open slot 6 and turned into the folding container, so that the side plate 1 is positioned above the side plate 3, and the side plate 1 and the side plate 3 are folded. Wherein, as shown in fig. 14, it is illustrated in fig. 14 that when the first hinge shaft 81 is at the bottom of the open slot 6, i.e., the first stopper 91 is inserted into the first top cutout 1211, the distance from the axis of the first hinge shaft 81 to the bottom of the first stopper 91 is H₃，D₂-D₁≤H₃So that the side panels 1 and 3 can be stacked with a sufficient space when the side panels 1 and 3 are folded. The distance D3, D from the axis of first hinge shaft 81 to the wall 12110 of first top cutout 1211₃≤H₃. The distance D from the groove wall 12110 of the first top cutout 1211 to the side plate body 11₅，D₅≥H₂。

It will be appreciated that the side panel body 31 of the side panel 3 may be 3, 4 or 5 folds. When folded, each adjacent folded portion is folded in half. The side plate bodies of the side plates 1, 2 and 4 can also be provided with a plurality of folding parts.

In addition, the side plate body 3 can also be a whole piece, in this case D₀-D₁≤H₃. It is understood that the side plate bodies of the side plates 1, 2 and 4 can also be one integral piece and have the same size ratio.

When folded, the side panels 2 and 4 can be folded in the same way as the side panels 1 and 3, and the dimensional proportionality is the same.

In addition, as shown in fig. 12, in the open slot 6 into which the socket plate 12 is inserted, a distance H between the axis of the first hinge shaft 81 and a side of the first stopper 91 facing the inside of the folding container₄，H₄≤D₁。

As shown in fig. 13 and 14, the axis of the first hinge shaft 81 is spaced apart from the groove wall 12120 of the first trailing cutout groove 1212Is separated to D₄，D₄≤H₃。

Further, as shown in fig. 3, 4, 5, 7, 9 and 15, a second hinge shaft 82 is provided on the second insertion portion 122 so as to oppose the first hinge shaft 81, and the second hinge shaft 82 is slidably and rotatably connected to the hinge table 7. A vertically arranged second slideway 702 is arranged on one side of the hinge table 7 facing the second groove wall 62, and the second hinge shaft 82 slides along the second slideway 702.

Further, as shown in fig. 2, 3, 7 and 15, the hinge table 7 is provided with a second blocking portion 72 protruding toward the second groove wall 62, and the second blocking portion 72 and the third groove wall 63 are spaced apart from each other to form a second slideway 702.

In addition, as shown in fig. 15, the second insertion portion 122 is opened toward the second groove wall 62 side with two second top cut grooves 1221 and second rear cut grooves 1222 spaced apart from each other, the second top cut grooves 1221 are provided at a side of the second insertion portion 122 toward the side panel body, and the second rear cut grooves 1222 are provided at a side away from the side panel body. The second limiting portion 92 is used for abutting against the second rear undercut 1222 when the side panel is folded; and also for inserting the second top undercut groove 1221 or the second rear undercut groove 1222 when the side panels are vertically mated with the base.

Specifically, when the side plate is mounted on the base, the side plate is vertically downward, as shown in fig. 3 and 7, the first rear cutout groove 1212 is aligned with the first limiting portion 91, the first limiting portion 91 moves along the first rear cutout groove 1212, the first hinge shaft 81 slides along the first slide way 701, the second rear cutout groove 1222 is aligned with the second limiting portion 92, the second limiting portion 92 moves along the second rear cutout groove 1222, and the second hinge shaft 82 slides along the second slide way 702. After the top of the first position-limiting portion 91 abuts against the groove wall 12120 of the first tail cut groove 1212 and the top of the second position-limiting portion 92 abuts against the groove wall 12220 of the second tail cut groove 1222, as shown in fig. 3 and 9, the side plate is turned inside the container, pulled to continue to slide downward until the first top cut groove 1211 is located at the first position-limiting portion 91 as shown in fig. 10, the second top cut groove 1221 is located at the second position-limiting portion 92, and then turned until the side plate is in a vertical state as shown in fig. 11, the first position-limiting portion 91 is embedded in the first top cut groove 1211, and the second position-limiting portion 92 is embedded in the second top cut groove 1221. First blocking portion 71 also blocks first articulated shaft 81, and first articulated shaft 81 will not break away from a mouthful groove 6, and second blocking portion 72 also blocks second articulated shaft 82, and second articulated shaft 82 will not break away from a mouthful groove 6 yet to the realization is with curb plate and pedestal mounting. It will be appreciated that the side panels 2, 3 and 4 may be mounted in the same way.

When it is desired to fold the side panels, as shown in fig. 3, 4, 5, 6 and 18, the side panels are turned inside the folded container, the first hinge shaft 81 rotates in the first slide 701, and the second hinge shaft 82 rotates in the second slide 702. The side plate 3 opposite to the side plate 1 also needs to be folded, the side plate 3 can be folded firstly in the same way, then the side plate 1 is folded, the side plate 1 can be pulled upwards in the folding process, the first hinge shaft 81 moves upwards in the first slide way 701, the second hinge shaft 82 moves upwards in the second slide way 702, and the folded side plate 1 is positioned above the side plate 3, so that the folding of the side plate is realized, and the transportation and the storage of the folded container are facilitated. It will be appreciated that the side panels 2 and 4 may be folded in the same way.

Further, as shown in fig. 16, 17 and 18, the distance between the top of the hinge table 7 and the top of the second stopper portion 92 is F1, the height of the second stopper portion 92 is F2, and the height from the axis of the second hinge shaft 82 to the bottom of the second undercut groove 1222 is G₁，F₁≤F₂-G₁. Thus when curb plate 1 and curb plate 3 are folding, and curb plate 1 level is emptyd and is located curb plate 3 top, though carrying drawing curb plate 1 and can beating, be located spacing portion 92 of second department, but second articulated shaft 82 is located second slide 702, and then the curb plate can not break away from the base easily.

In addition, as shown in fig. 16, 17 and 18, when the second stopper portion 92 is inserted into the second undercut groove 1221, the distance from the axis of the second hinge shaft 82 to the bottom of the second stopper portion 92 is F₃. The side panel body 31 includes a folded portion 311 and a folded portion 312, and the folded portion 312 and the folded portion 311 are stacked at a height D after being folded in half₂，D₂-D₁≤F₃. First, theThe distance G from the axis of the two hinge shafts 82 to the groove walls 12210 of the second undercut grooves 1221₃，G₃≤F₃. When folded, the side panels 2 and 4 can be folded in the same way as the side panels 1 and 3, and the dimensional proportionality is the same. The groove wall 12210 of the second undercut groove 1221 is spaced from the side plate body 11 by a distance G₅，G₅≥F₂。

In addition, the side plate body 3 can also be an integral piece, and the thickness of the side plate body 3 is D₀，D₀-G₁≤F₃. It is understood that the side plate bodies of the side plates 1, 2 and 4 can also be one integral piece and have the same size ratio.

In addition, in the open slot 6 into which the socket plate 12 is inserted, the distance F between the axis of the second hinge shaft 82 and the side of the second stopper 92 facing the inside of the folding container₄，F₄≤G₁。

As shown in fig. 16 and 17, the axis of the second hinge shaft 82 is spaced from the groove wall 12220 of the second trailing cutout groove 1222 by a distance G₄，G₄≤F₃。
