Abstract:
A threaded-connection anti-loosening locking device includes: a bolt ( 4 ) having an external thread screw, a nut ( 3 ) having an internal thread, a locking member for locking rotation of the nut on the bolt, and a locking pad ( 1 ) for further limiting rotation of the locking member. By means of matching of the locking member and the locking pad ( 1 ), the rotation of the nut can be prevented by utilizing the matching relationship of mutual locking during vibration, and the current fixation relationship can be prevented from being loosened.

Claim (Index 1):
A threaded connection anti-loosening locking device, comprising:\n a bolt having a screw with an external thread; a nut having an internal thread and forming a threaded connection with the threaded screw; a locking element having a cylindrical body with a through hole, an axial cross-sectional shape and size of the through hole corresponding to an axial cross-sectional shape and size of the outer surface of the nut, and a locking ring buckled at the cylindrical body being provided at one end of the cylindrical body, the center of the stop ring being provided with a round hole with the same outer diameter as the screw, and a gripping pattern being arranged on a side of the lock ring away from the cylindrical body; and a lock washer having a through hole arranged at its center whose diameter is the same as an outer diameter of the screw and having a gripping pattern on one side of the locking washer that is in contact with the gripping pattern of the locking ring for preventing relative rotation.
