Twist lock used for connecting corner fittings of container

Abstract

The invention provides a brand-new fifth three feet gooseneck type container which can be simultaneously used for land transportation and marine transportation; a gooseneck type groove with the depth of 120mm is arranged on the bottom surface of the container; one or a plurality of beams are evenly distributed in the gooseneck type groove; and the height of each beam is 41mm. The invention also provides a twist lock which is used for connecting a corner fitting of the fifth three feet container; the twist lock comprises an upper lock head, a lower lock head and a base, wherein the base comprises an upper end part, a lower end part and a middle part; and when the middle part is connected with the corner fitting, the area of the surface of the middle part which is contacted with the corner fitting is approximately equal to the area of the bottom surface or top surface of the corner fitting. The adoption of the fifth three feet container and the twist lock manufactured according to the invention can realize the stack placement of a plurality of containers for marine transportation so as to greatly reduce the transportation cost and shorten the transportation cycle of cargoes.

Description

technical field [0001] The invention relates to a container, in particular to a 53-foot container that can be used for road, rail and sea transportation at the same time. Background technique [0002] Containers have been used in the transportation of goods since the mid-1950s. Unlike the previous single mode of transportation that only relied on railways, roads or water transportation, container transportation can greatly reduce the cost of transshipment, reducing the cost and time of cargo transshipment. Today, container shipping has become the most advanced means of transportation in global trade. [0003] Currently, 53-foot container containers are used on intermodal lines in the United States. But so far no 53-foot containers have been used on ocean lines. Imported goods in the United States are generally transported by sea to U.S. ports in 20, 40 or 45-foot containers, then transferred to 53-foot containers, and then transported to their final destinations by road o...

AI Technical Summary

Problems solved by technology

When the container is transported by sea, the container will swing left and right due to the turbulence of the sea waves. Because the corner hole deviates from the corner post and the support force is uneven, it will put pressure on the hinge part of the container door, which will cause cracks in the hinge part for a long time, resulting in container damage

Therefore, the existing twist-lock structure cannot adapt the container to the bumpy environment of sea transportation
