Abstract
The utility model discloses a loosening prevention structure for the connection of a hydraulic cylinder. The structure comprises a piston rod end which is in threaded connection with a connecting piece. A first permanent magnet is arranged at a joint of the piston rod end and the connecting piece. A second permanent magnet is arranged at a joint of the connecting piece and the piston rod end. By attractive force generated by the first and second permanent magnets, the piston rod end and the connecting piece can be prevented from being loosened.
