The invention discloses an anti-loosening structure. The anti-loosening structure comprises a forklift chassis, a battery dragging frame, a drag hook plate, a rotating sleeve and an extension spring. The battery dragging frame is arranged in the middle of the forklift chassis, a middle rib plate is arranged in the middle of the battery dragging frame, and a first positioning pin is arranged at the rear end of the middle rib plate. A first through hole is formed in the middle of the drag hook plate, one end of the drag hook plate is in a hook shape, and a second positioning pin is arranged at the other end of the drag hook plate. The rotating sleeve is arranged inside the first through hole, and a screw penetrates through the rotating sleeve to fix the drag hook plate to the front end of the middle rib plate in a hinged mode. A fixing shaft is arranged on the forklift chassis, one end of the extension spring is connected with the first positioning pin, the other end of the extension spring is connected with the second positioning pin, at the moment, the extension spring is in an original state, and spring force is not generated. By the application of the anti-loosening structure, the end, in the hook shape, of the drag hook plate can be manually arranged on the fixing shaft in a sleeving mode, at the moment, the extension spring is in an extension state, with the help of the spring force, the battery dragging frame is tightly fixed to the forklift chassis, operation is easy, and time and labor are saved.
