The top ends of the screws 131 of the fixing legs 130 attached to the top beam 111 are provided with a pressing head 133 located above the top beam 111. The outer ends of the screws 131 of the fixing legs 130 connected to the upright 112 are provided with pressing heads 133 positioned at the outer sides of the upright 112, and the frame 100 can be effectively fixed in the cabin 800 by the pressing heads 133 on the fixing legs 130 abutting against the inner wall of the cabin. The pressing head 133 is connected with the ball 134 on the screw 131, so that the pressing head 133 can rotate relative to the ball to be better attached to the inner wall of the carriage 800.
As shown in fig. 1, the upper carrier 200 includes a bottom frame 210 and a pallet 220 disposed on the bottom frame 210, the pallet 220 has a square shape, and at least one side of the pallet 220 is parallel to the length direction of the frame. When the upper rack 200 is in the unfolded state, the supporting plate 220 is above the bottom frame 210, and at this time, the top surface of the supporting plate 220 is the bearing surface of the roll-over stand.
As shown in fig. 6, the side of the bottom frame 210 near the side frame 110 is hinged to the side frame 110, and a torsion spring 230 is further sleeved on the hinge shaft of the side frame 110 and the bottom frame 210, and the torsion spring 230 keeps the upper carrier 200 in a unfolded state in a normal state.
The upper rack 200 on each side may be a member, i.e., the length of one of the upper racks (the distance the upper rack extends along the length of the frame 100) is comparable to the length of the frame or compartment, and such a structure may facilitate folding and unfolding of the upper rack 200.
As shown in fig. 1, the upper carriers 200 on each side are multiple, they are separated from each other and are arranged at equal heights, and the lengths of the upper carriers 200 on each side may be the same or different, and the lengths of the upper carriers 200 on one side may be designed according to actual needs, preferably, the lengths of all the upper carriers 200 are the same and the length of each upper carrier is approximately 1/4 of the length of the frame.

When the goods are placed on the rollers 240 and moved, the rotation of the rollers 240 may reduce friction, thereby making the movement of the goods smoother.
In order to avoid that goods cannot be stably transported due to easy rolling and shaking of the goods on the rollers 240 during transportation, the axes of the adjacent rollers 240 are vertical, a group of rollers arranged along the depth direction of the carriage is defined as a row, and a group of rollers arranged along the depth direction of the carriage is defined as a row, namely, in a row of rollers, the axes of two adjacent rollers are vertical, and the axes of two rollers opposite to each other in the adjacent row are also vertical, and the axes of part of the rollers 240 in each row of rollers 240 extend horizontally and are vertical to the depth direction of the carriage, so that the design can increase resistance to a certain extent and reduce the moving and shaking conditions of the goods during transportation.
Or the axes of the rollers of adjacent rows or columns are made perpendicular to each other, i.e., the axes of one row or column of rollers extend in a direction perpendicular to the depth of the vehicle cabin, and the axes of the rollers of one or two rows or columns adjacent to the row or column extend in a direction parallel to the depth of the vehicle cabin.
As shown in fig. 1, when the upper carrier 200 is folded, the upper carrier 200 tends to fold under the action of gravity and the torsion spring 230, and in order to avoid the upper carrier 200 from folding automatically, the upper carrier 200 is kept folded by the quick manual clamp 300 and/or the limit pin when the upper carrier 200 is turned to the folded state.
As shown in fig. 1 and 2, the length of the bottom frame 210 of the upper carrier 200 does not exceed the distance between two adjacent columns 112, and at least one side of the bottom frame 210 has a wing plate 211 extending to the outside of the bottom frame 210, in the folded state of the upper carrier 200, the wing plate 211 abuts against the baffle plate 115 of the column 112, and meanwhile, a quick manual fixture 300 is provided on the baffle plate 115, and the specific structure of the quick manual fixture 300 is a known technology, for example, may be a structure disclosed in the authorized publication number CN 214686129U.
