Embodiment 1
[0045] like figure 1 and figure 2 As shown, the present invention discloses a foldable multi-purpose standard container, including a main box body 1 that plays a load-bearing role and two auxiliary boxes 2 that can be inserted into the main box body 1, and the shape of the main box body 1 is The size is the same as that of a 20-foot standard container. The auxiliary box 2 is symmetrically arranged at both ends of the main box 1; , the longitudinal load-bearing beam 11 has a square hole 111 of hollow structure; One side is provided with a load-bearing square frame 22, and the load-bearing square frame 22 includes a box body door frame 221 and a box door 222, and the peripheral side of the box body door frame 221 is inherently welded with a secondary top plate 23, a secondary bottom plate 24, and a secondary side plate 25, The main box body 1 is provided with a main top plate 14, a main bottom plate 15 and a main side plate 16, and the auxiliary top plate 23, the auxiliary bo...
Embodiment 2
[0052] Figure 1 to Figure 5 As shown, when any shaft head of the power vertical shaft 35 or the power flat shaft 36 inputs clockwise rotation power, the four transmission worm gears 33 drive the four screw power shafts 31 to rotate synchronously, and the outer end shafts of the four screw power shafts 31 The four internally fixed four drive nuts 32 of the two sub-boxes 2 connected by the head are stressed, and slide out to the two outer ends of the main box 1 respectively, so that the two sub-boxes 2 protrude outward respectively, and the main The total length of the box body 1 and two auxiliary box bodies 2 at both ends is a 40-foot container with double doors at both ends, and the box type of the 40-foot container is suitable for shipments with smaller specific gravity and larger cargo volume.
Embodiment 3
[0054] Figure 1 to Figure 5 As shown: when any one of the power vertical shaft 35 or the power flat shaft 36 inputs counterclockwise rotation power, the four transmission worm gears 33 drive the four screw power shafts 31 to rotate synchronously, and the outer end shafts of the four screw power shafts 31 The four internally fixed four transmission nuts 32 of the two sub-boxes 2 connected by the head are stressed and slide towards the longitudinal center of the main box 1 respectively, so that the two sub-boxes 2 slide into the main box 1 respectively. In the middle, when the main box body 1 and the two auxiliary box bodies 2 are all overlapped, the box type is a 20-foot container with double doors at both ends, and the box type of the 20-foot container is suitable for a box-shaped state with a larger specific gravity and a smaller volume.
