Freight container

Abstract

A freight container includes a container body (1) and corner fittings (2) provided at each corner of the container body. The container body (1) includes a bottom (10), a top (20), two side portions (30) and two end portions (40, 50), and at least one end portion is provided with locking devices (60) or corrugated plates (70). The locking devices (60) or corrugated plates (70) protrude beyond the outer edges of the corner fittings (2), and the position of each corner fitting and the distance therebetween accord with ISO standards. The inner length of the container is enlarged by extending outwards the rear end and/or the front end to the outer edges of the locking devices (60) or corrugated plates (70) beyond the corner fittings. The position of the corner fittings in the container and the relative distance therebetween are constant and accord with ISO standards, hence without influencing the alignment of the spreader and the corner fittings. Therefore, the inner space of the improved container is enlarged and the improved container still adapts to the existing standard products. Compared with the prior containers provided with locking bars having special structure, the present container is easy to implement and the manufacturing difficulty is small.

Description

technical field [0001] The present invention relates to the field of freight containers. Background technique [0002] The main body of an ordinary freight container generally includes a box body surrounded by a bottom, a top, two sides, a rear end, and a front end, and corner fittings for each top corner of the box body. figure 1 is the top view of the existing 20' container 200, figure 2 for figure 1 side view of the container shown, image 3 its other side view. Such as figure 1 , 2 , 3, the front end 22 is provided with a wave plate 24, and the concave and convex portions of the wave plate 24 are arranged symmetrically with respect to the center line of the front end 22. The rear end 23 is provided with a locking device 25, and the locking rods 251 of the locking device 25 are symmetrically arranged on the two doors. The corner fittings 26 are located at the top corners of the container, and the positions of the corner fittings and the distance between the corner...

Problems solved by technology

Therefore, if the above-mentioned ordinary cargo container is still used to ship pallets, the ISO20' box cannot hold 5 rows of pallets, and although the ISO40' box can theoretically arrange 10 rows of pallets, due to the need to leave enough space between the pallets (generally The length needs to be more than 12060mm) to actually arrange 10 rows of pallets, so when using ISO containers to ship pallets, it will cause a waste of space in the box

Similarly, it is difficult to install 17 rows when shipping 1200x800mm pallets in ISO45' boxes

Therefore, when the existing ISO-compliant containers are loaded on pallets, due to the unreasonable design of the size of the pallet and the size of the box, it is impossible to arrange as many pallets as possible, resulting in a waste of space in the box

[0004] In order to maximize the size of the box, a special container door structure is introduced in the patent document (publication number: CN2213134A), which hides the lock bar in the door frame and increases the volume of the box as much as possible. This structure is difficult to manufacture, and the increase in the length of the box is limited
