Abstract

The invention belongs to the technical field of fasteners, and particularly relates to an anti-theft fastening bolt and a nut thereof. The anti-theft fastening bolt comprises a base, a fastened piece, a stud, the nut, stop blocks, elastic elements and an elastic pad. According to the anti-theft fastening bolt and a nut thereof, through arranged special-shaped threads, when the nut is rotated in the clockwise direction, the stop blocks make contact with the advancing ends of the special-shaped threads, then the ends, making contact with the advancing ends, of the stop blocks slide on the advancing ends, due to the fact that the advancing ends are inclined curved surfaces, the stop blocks move in the direction away from the stud while rotating along the stud, and thus the stop blocks completely enter sliding grooves, so that the clockwise rotation of the nut is not restrained, and the nut is tightened; and one ends of the stop blocks enter grooves, when the nut is rotated in the counterclockwise direction so as to relieve the fastening of a part, one sides of the stop blocks abut against the retaining ends of the special-shaped threads, the rotation of the nut in the counterclockwise direction is limited, and the dismounting of the nut is limited, so that the anti-theft effect is achieved.

Description

technical field

[0001] The invention belongs to the technical field of fasteners, in particular to an anti-theft fastening bolt and a nut thereof. Background technique

[0002] Fastening bolts: mechanical parts, cylindrical threaded fasteners with nuts, a type of fasteners consisting of two parts, the head and the screw (cylindrical body with external threads), need to be matched with nuts, used For fastening two parts with through holes, this connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection bolt is to use the physical and mathematical principles of the oblique circular rotation and friction of the object to fasten the object step by step Tools for machine parts, both ordinary and for reaming holes. Ordinary ones mainly bear axial force, and can also bear less demanding lateral force. The bolts used for reaming holes should match the size of the holes and be ...
