Description

Technical Field:

[0001] The utility model belongs to the technical field of container installation, and particularly relates to a connecting, fixing, locking and tightening device for the box plates of a bulk folding container. Background Art:

[0002] At present, there is a large trade gap among countries around the world. During the sea and land transportation of a large number of containers, the empty container rate in the round trip is too high. Due to the limited space in the transportation vehicle cabins, it is difficult to obtain a cabin and the transportation cost is too high. In order to reduce the space occupied by containers, improve the utilization rate of the cabin, and achieve the effect of energy conservation and emission reduction, manufacturers have designed and produced containers that can be shrunk and folded, ensuring that more than 2 - 4 containers can be stacked in one cabin.

[0003] For the existing containers that can be shrunk and folded, the box plate connection and locking device has the following problems: 1. It can be randomly opened and closed without using special tools, which may cause the container to be accidentally opened by someone without supervision and inspection, resulting in the decoupling, separation and collapse of the container, and causing safety risks such as damage or loss of goods and injury or death. 2. During the locking and connecting process, the two actions of locking and tensioning cannot be achieved simultaneously, and the gap problem at the connection part cannot be guaranteed. Exceeding the tolerance and large gaps will cause the box body to vibrate during transportation. It is very easy for the connection and locking device to be decoupled during the loading and unloading of heavy goods and transportation after the container is opened, resulting in the container falling apart.
