The utility model discloses a walking mechanism of an anti-corrosion operation and maintenance robot for a steel box girder structure bridge, which belongs to the technical field of robots and comprises a base, and anti-corrosion equipment is mounted on the base. Each walking part comprises a driving assembly connected to the bottom of the base, the output end of each driving assembly is connected with a connecting frame, a plurality of sliding grooves are formed in the bottom of the base, and the multiple sliding grooves correspond to the multiple walking parts in a one-to-one mode. According to the walking mechanism, the sliding groove with the two low ends and the high middle is formed, when the driving assembly drives the sliding block to move through the connecting frame and the connecting column, the sliding block moves from one end of the sliding groove to the other end of the sliding groove, the sliding block can conveniently drive the moving wheels to cross a gap through the mounting frame, and the walking mechanism can freely walk on a bridge floor; meanwhile, the moving wheels rise and then fall in the process of crossing the bridge deck gap, collision between the moving wheels and the bridge deck gap is effectively avoided, and the moving wheels and the bridge deck are protected.

The application relates to the field of packaging boxes, in particular to a multifunctional plastic packaging box which comprises a box body, a storage box is arranged on the inner side of the box body, a limiting plate is arranged on the lower end surface of the storage box, a driving assembly is arranged between the limiting plate and the storage box, a sliding groove is arranged on the inner wall of the box body at the corresponding position of the limiting plate, a through hole is arranged on the box body at one side of the storage box, and an elastic assembly is arranged on one side of the box body. The limiting plate, the sliding groove, the push plate, the baffle and the spring II are arranged, the sliding groove and the limiting plate are matched with each other during use, so that the position of the storage box is limited, the baffle is driven to rotate to release the limitation on the storage box, and one end of the storage box is pushed out of the box body from the through hole under the action between the spring II and the push plate, so that the effect that a staff member can directly take out the articles from the side is achieved, and the convenience of the staff member is improved.
