The type of container commonly used in general cargo transportation is a dry container (dry container), and its specifications mainly include 20-foot containers (outer dimensions About 20 feet in length x 8 feet in width x 8 feet 6 inches in height, that is, about 6.058 meters in length x 2.438 meters in width x 2.591 meters in height), 40 feet container (that is, the length is 12.192 meters, and the other dimensions are the same as those of 20 The same size cabinet), etc. Only when the container is unloaded and unused, it is often stored in the container storage yard or general space, and the huge volume of the empty container causes a great waste of storage, and when storing the container, it is often necessary to stack the container with a spreader , to achieve space utilization; because the height of each container is 2.591 meters, the stacking height of several layers of containers is considerable, so that stacking is very troublesome and potentially dangerous. In addition, empty containers are being transferred 1. When moving, limited by the fixed volume of the empty container, the benefit of transporting it by a specific transportation method (such as a container-connected vehicle) is low, and only a certain number of empty containers can be transported to a limited extent, resulting in huge transportation costs.

A kind of collapsible container adopted by people in the transportation industry at present, as the disclosed collapsible container of CN2761544Y as Chinese Patent Publication No., has just solved the above-mentioned technical problem. The structure of this folding container includes a chassis, a top plate relative to the chassis, two opposite side plates, a front end plate and a rear end plate relative to the front end plate, which together form a rectangular body; it is characterized in that: the front end The plate and the rear end plate are pivotally connected to a front end and a rear end of the chassis respectively, and each side plate has an upper side plate and a lower side plate, wherein an upper end of the upper side plate is pivotally connected to the top plate On one side, the lower end of the lower side plate is pivotally connected to one side of the chassis, and the lower end of the upper side plate is pivotally connected to an upper end of the lower side plate; the container structure additionally includes a The fixing device is arranged inside the rectangular body, so that the front end plate and the rear end plate do not pivot with the chassis, and the upper side plate and the lower side plate do not pivot with each other. And make the formed rectangular body have sufficient rigidity and strength.

The steps of folding the container are to hook the front panel and the rear panel with the spreader frame, and the operator respectively opens the fixing components of the front panel and the rear panel, and slowly lets the front panel and the rear panel dump on the inner chassis of the container; The top frame is hung by the spreader, and the operator opens the fixed components inside the container so that the frame of the container can be folded slowly. Use the fixed locks to fix the container corners at the four corners of the upper frame and the lower frame, so that the container is fixed in the folded state, which is convenient for handling and storage.

Since the above-mentioned rear end plate, that is, the container door is pivotally connected to the chassis, it does not meet the technical specifications for the opening of existing container containers, and cannot be applied to various transportation equipment for current cargo transportation.

In addition, one side of the two container doors on the rear side of the current container is hinged by eight hinge plates and door corner posts, four on each side. Since the container door does not need to be folded, these hinge plates and the container door are welded together, and thus are not suitable for the folding cabinet invented by the inventor.
