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 5):
The threaded connection anti-loosening locking device according to  claim 4 , wherein the gripping pattern on the locking washer corresponds to the shape of a stepped gear stair on the locking ring, and the ramped surfaces of the stepped gear stair have the same rising angle but in opposite rotation directions.
