Description

removable pallet box

technical field

The utility model relates to a transport container, in particular to a detachable pallet box.

Background technique

As a common logistics transportation container, pallet box has been more and more widely used. Generally speaking, a pallet box includes a chassis, and two side walls and two end walls respectively arranged on the chassis. Wherein, the two side walls are arranged opposite to each other on the two side edges of the chassis, and the two end walls are arranged opposite to each other on the two end edges of the chassis.

Most existing pallet boxes adopt a fixed structure, wherein adjacent side walls and end walls are fixed to each other and to the chassis respectively. This kind of fixed pallet box takes up the same space when it is empty as when it is full, and the space utilization rate is low, resulting in higher costs for empty-load transportation and storage. In addition, since the side walls and end walls are fixed to the chassis, this pallet box is not suitable for those occasions where only the chassis is required to be used as a pallet.

Now there is a collapsible pallet box whose four walls are connected to the chassis in a folding structure. The side and end walls can be folded onto the chassis when empty. Although this kind of pallet box solves the problem of large space occupied by empty boxes, since the folded walls cannot be separated from the chassis, when only the chassis is used to load goods, the folded walls placed on the chassis are not convenient for placing and transporting goods operate. In addition, the folding mechanism is relatively weak and easily damaged, especially when transporting heavy cargo.

There are also demountable pallet boxes in which the side and end walls are detachable from the chassis. However, this type of pallet box usually uses more locks and connectors to realize the connection between the chassis and the side wall/end wall, and the operation is cumbersome when disassembling and assembling. High cost and long manufacturing hours.

When needed, the end wall 20 and the side wall 30 can be detached from the chassis 10 and connected together, which will be described in detail below.

As shown in FIG. 2 , the end wall 20 of the pallet box has two sides 21 . After assembly, the end wall 20 is mated with the adjacent side wall 30 through the side edge 21 . An upper beam 22 and a lower beam 23 are respectively arranged at the top and bottom of the end wall 20 , and one or more intermediate beams 24 may also be arranged in the middle of the end wall 20 . At least one protrusion is provided on each side 21 . For example, a protruding portion may be provided at the top and middle of each side 21, wherein the first protruding portion 25 at the top of the side 21 is set to protrude outward from the end of the upper beam 22, and the first protruding portion 25 at the middle of the side The second protrusion 26 is provided to protrude outward from the end of the intermediate beam 24 . It should be clear that the number and configuration of the protrusions can be determined according to actual needs.

As shown in FIG. 3 , the side wall 30 includes two upright posts 31 respectively located on both sides thereof for cooperating with the side edges 21 of the adjacent end wall 20 to realize the connection between the end wall and the side wall. An upper crossbeam 32 and a lower crossbeam 33 may be respectively provided at the top and bottom of the sidewall 30 , and one or more intermediate crossbeams 34 may be provided at the middle of the sidewall 30 . Each column 31 is provided with at least one matching hole for matching with at least one protrusion on the corresponding end wall side 21 . Here, two matching holes 35 , 36 are provided on each column, and their structures and positions correspond to the first protruding portion 25 and the second protruding portion 26 respectively.

When it is necessary to connect the end wall and the side wall, the protruding parts 25, 26 on one side of an end wall can be respectively inserted into the matching holes 35, 36 on the corresponding column of a side wall; The protrusion on the other side of the wall is inserted into the matching hole on the corresponding column of the other side wall; finally, in the same way, the protrusions on the two sides of the other end wall are respectively inserted into the corresponding columns of the two side walls in the mating hole on the In this way, the four walls of the pallet box are assembled into a whole, called a wall assembly, as shown in Figure 4. Preferably, the positions of the protrusions and corresponding fitting holes are suitably set such that the walls in the wall assembly are substantially flush in height. For example, in FIG. 4, the upper beam 22 and the lower beam 23 of the end wall are aligned with the upper beam 32 and the lower beam 33 of the side wall, respectively.

Here, adjacent end walls and side walls are connected through a combination of two sets of protrusions and matching holes, so that the connected end walls and side walls do not rotate relative to each other, improving the reliability of the connection. Of course, adjacent end walls and side walls may also be connected to each other only through a combination of a set of protrusions and matching holes. The set of protrusions and cooperating holes may be configured in any known configuration that prevents rotation of the end and side walls relative to each other.

The stacking seat 17 and the corresponding corner column 15 can be arranged as an integral structure to improve the structural strength and bearing capacity of the chassis. The structure of the stacking seat 17 is set so that it can cooperate with the top of the side wall column, and also can cooperate with the top of the chassis corner column 15 . In this way, when the pallet box is used as a whole, multiple pallet boxes 100 can be stacked through the cooperation of the stacking base 17 and the side wall column 31 , as shown in FIG. 9 . Where it is desired to use the chassis alone, the wall assembly can be removed from the chassis as a whole. At this time, multiple chassis 10 can be stacked through the cooperation of the stacking base 17 and the corner column 15 .

As shown in FIG. 5 , a pair of fork grooves 18 are also provided on the bottom of the chassis, so as to facilitate the stacking work by using a forklift. Here, the fork pockets 18 are arranged perpendicular to the end edge 12 of the chassis. Of course, the fork grooves can also be arranged perpendicular to the side 13 of the chassis; or a pair of fork grooves can be arranged in a direction perpendicular to the end edge 12 and the side edge 13, so as to meet the needs of multi-directional fork entry.
