They are mainly used in logistics systems that are compatible with ships, ports, routes, roads, transfer stations, bridges, tunnels, and multimodal transport. Containers are used to transfer goods. Goods can be loaded directly at the shipper's warehouse and unloaded at the consignee's warehouse. When changing vehicles or ships in the middle of the journey, there is no need to take the goods out of the box for reloading. At present, when the existing containers need to be changed for transportation after transportation, the bolts need to be loosened before the containers can be disassembled. This method will increase the cumbersomeness of container disassembly, the disassembly operation process is cumbersome, and the disassembly efficiency is low.

The other end of the first push spring 11 is pressed against the side of the first positioning plug 8 and the second positioning plug 9.

[0031] It is worth mentioning that the first positioning plug 8 and the second positioning plug 9 can be supported and positioned by the positioning rod 10 and the positioning hole 12, so that the first positioning plug 8 and the second positioning plug 9 can move smoothly, and the first positioning plug 8 and the second positioning plug 9 can be pushed by the first push spring 11, so that the first positioning plug 8 and the second positioning plug 9 can be plugged into the base 4, thereby realizing automatic locking of the container;

[0032] The first electromagnet 18 is disposed inside the first positioning plug-in block 8 and the second positioning plug-in block 9;

[0033] It is worth noting that the first electromagnet 18 can improve the stability of the first positioning plug 8 and the second positioning plug 9, so as to facilitate the positioning and fixing of the base 4;
