Abstract
The invention belongs to the technical field of pressure tanks, and relates to an automatic locking device for a tank cover of a pressure tank. The pressure tank comprises a pressure tank body and the tank cover covering an opening of the tank body. Three or more fixing seats are arranged on the outer wall of the opening of the tank body at intervals in the circumferential direction. A hinging portion in the middle of each locking block is hinged to the corresponding fixing seat through a hinging shaft, a locking hook is arranged on the upper side of each locking block, and a driving arm is arranged on the lower side of each locking block. A driving ring is arranged on the lower sides of the driving arms, driven by a power device to move up and down and mounted on the outer wall of the pressure tank in a sleeving mode. The driving ring is provided with wedge blocks driving the driving arms to rotate around the hinging shafts. After the tank cover covers the opening of the tank body and the power device drives the driving ring and the wedge blocks to move upwards, the wedge blocks drive the driving arms to rotate so as to enable the locking hooks of the locking blocks to clamp the upper surface of the tank cover, and automatic locking of the tank body and the tank cover is achieved. The automatic locking device has the advantages that the tank body and the tank cover are automatically locked, locking stability is good, friction force is small, and the automatic locking device is suitable for automatic locking between the tank body and the tank cover of a small pressure container.
