Abstract

A frame and a pallet coaming box, the frame () comprising: two long side plates () and two groups of short side plates () opposite thereto, each group of short side plates () comprising two short side plates (), wherein the two short plates () are capable of being folded over each other, and the long side plates () and the short side plates () that are next to each other are capable of being folded over one another; one of the two short side plates () being provided with at least one first engaging portion (), and the other short side plate being provided with a second engaging portion () matching the first engaging portion; a locking device () being further arranged between the two short side plates (), the locking device () comprising an operating member (), a locking member (), and a locking structure () matching the locking member (); the locking member () being mounted on a short side plate (), the locking structure () being arranged on the other short side plate (), and the operating member () operatively driving the locking member () to mutually lock or separately unlock with the locking structure () so as to lock or unlock the two short side plates (). The frame minimizes outward deformation of side plates caused by engagement, and improves stability of containers during loading, transporting or stacking.
