Detachable bottom side beam locking device used for container

The utility model relates to the field of containers and provides a detachable bottom side beam locking device used for a container. The locking device comprises a bottom side beam, a locking rod, a handle and locking hook mechanisms. The locking rod is connected inside the bottom side beam in a penetrating mode and is in a rotatable state, and the handle is connected to one extending end of the locking rod. Detachable bottom side beam locking device is characterized in that the one or more locking hook mechanisms are connected to the locking rod, one or more bracket mechanisms are further connected to the locking rod, and the bracket mechanisms and the locking hook mechanisms are arranged alternately. When damaged, locking hooks or brackets can be detached and replaced, and therefore cost is saved; due to the multiple locking mechanisms, reliability of the locking device is improved.
