Side wall unit of pallet box and pallet box comprising same

Abstract

The invention discloses a side wall unit of a pallet box, and the pallet box comprising the side wall unit. The side wall unit comprises a side wall, a half folding door and a connection device; an opening is arranged at the upper part of the side wall; the lower end of the half folding door is connected on the side wall through the connection device in a pivoting manner, so that when the half folding door is closed, the opening is closed. The side wall unit is characterized in that a first connection beam is arranged at the lower end of the half folding door; the first connection beam comprises a lug which is stretched downwards; the lug faces to the inner side of the pallet box when the half folding door is closed; a second connection beam is arranged on the lower edge of the opening of the side wall; the second connection beam comprises a recess capable of containing the lug; and the recess faces to the inner side of the pallet box. The side wall unit of the pallet box disclosed by the invention can prevent the half folding door from being protruded towards the outer side of the pallet box, so that the integral rigidity of the side wall unit is improved; and besides, the side wall unit has the advantages of simple structure, low cost, convenience in installation, attractive appearance, etc.

Description

technical field [0001] The invention relates to the field of transportation equipment, in particular to a side wall assembly of a pallet box and a pallet box containing the side wall assembly. Background technique [0002] For the convenience of loading and unloading goods, half-fold doors are usually provided on the side walls of pallet boxes. The half-fold doors can be connected to the side walls through a single-axis hinge connection device to form a side wall assembly, but the use of this connection method will make the single-axis hinge connection The device protrudes from the side wall structure, so existing pallet boxes usually use a biaxial hinge connection device to connect the half-fold door and the side wall. Figure 1A and Figure 1B They are respectively a side sectional view and a front view of a side wall assembly 100 of a conventional pallet box. like Figure 1A and Figure 1B As shown, grooves 112 and 122 are respectively provided on the connecting beam 11...

AI Technical Summary

Problems solved by technology

In addition, since the side wall assembly only relies on the biaxial hinge connection device 130 to connect the half-fold door 110 and the side wall 120, the rigidity is poor.

Further, since multiple sets of biaxial hinge connection devices 130 are provided, the installation process of the side wall assembly 100 is cumbersome and the production cost is relatively high
