The invention provides an anti-loosening hinged structure for engineering machinery, and belongs to the technical field of engineering machinery parts. The anti-loosening hinged structure for the engineering machinery is used for connection of a front frame and a back frame of an engineering vehicle and comprises a hinged pin and a slotted nut, the front frame and the back frame are arranged on the hinged pin in a sleeving mode, and the front frame and the back frame can rotate around the axis of the hinged pin relative to the hinged pin; one end of the hinged pin is provided with a limit portion used for preventing the front frame and the back frame from being disengaged from the hinged pin in the axial direction of the hinged pin; the other end of the hinged pin is provided with an outer thread, and the slotted nut is in threaded connection with the hinged pin through the outer thread; the anti-loosening hinged structure for the engineering machinery further comprises a split pin, and the slotted nut is fixedly connected with the hinged pin through the split pin. According to the hinged structure, the locking effect is good, the slotted nut cannot relatively rotate with the hinged pin, the slotted nut is not prone to being loosened, use is safe, and the service life is long.
