The utility model relates to the technical field of positioning of a pressure container gas cylinder in a container storage device, in particular to a storage box for preventing the gas cylinder from toppling over. A balance weight column is arranged in the storage box body, the two sides of the balance weight column are divided into independent unit bins through vertical plates, and extension plates for providing transition for a basic face and the bottom faces of the unit bins are arranged on the outward sides of the bottoms of the unit bins. At least one sliding groove is formed in the surface of each vertical plate, slidable hook bodies are arranged in the sliding grooves, the hook bodies in the unit bins are connected through lock chains, and the lock chains limit the positions of gas cylinders stored in the unit bins. According to the storage box, the overall stability is taken into consideration, meanwhile, the operation difficulty in the process of carrying the gas cylinders in and out of the box body
