Lock structure for hazardous solid waste transfer container and industrial hazardous waste storage and transportation container

An embodiment of the invention discloses a lock structure for a hazardous solid waste transfer container and an industrial dangerous waste storage and transportation container, and relates to the technical field of chemical environmental protection, so as to improve the leakproofness of the container and improve the safety in an environment that a large number of containers are stacked together. The lock structure comprises a lock rod and a lock box. A limiting device and a locking mechanism are arranged in the lock box, the lock rod can pass through the limiting device, and a gear is installed in the locking mechanism. A rack is machined on the lock rod, extends into the limiting device in the lock box from the outside and is matched with a gear in the lock box, so that a container coverof the industrial hazardous waste storage and transportation container can tightly cover a container shell, and a sealed state is formed. The invention further provides a locking and unlocking methodfor the lock structure and
