A novel anti-loose bolt assembly comprises a bolt, a nut and a locking plate; the bolt is provided with a gasket and a nut, and a locking plate is arranged between the gasket and the nut on the bolt;
a clamping groove is axially formed in the bolt;
the locking plate is of an annular structure, the inner ring of the locking plate is provided with a clamping protrusion matched with the clamping groove, the periphery of the locking plate is provided with locking teeth, and the locking teeth are turned upwards through external force to hold the nut, so that the nut cannot rotate.
Preferably, the locking plate has an outer diameter greater than an outer diameter of the nut.
Preferably, at least one bolt clamping groove is formed in the bolt clamping groove.
Furthermore, the cross section of the clamping groove is of a semicircular structure.
Further, the length of the clamping groove penetrates through the whole thread on the bolt.
Preferably, in the present invention, another form of the locking plate is: the locking plate is of an annular structure, at least one through hole is formed in the annular surface of the locking plate, and the through hole is located in the outer side of the nut after the locking plate and the nut are coaxially overlapped.
Furthermore, after the nut is installed in place, a rivet is arranged in the through hole, and the nut is clamped by the rivet and cannot rotate.
The beneficial effects of the utility model reside in that:
the mode simple structure that this application realized the nut need not adopt the special relation to the nut, has reduced lockbolt subassembly's the processing degree of difficulty lower limit for even the nut damages the back, change also convenience very, ordinary nut also can make it reach locking effect.
The application expands the market types of the anti-loosening bolts and provides more selectivity for the market.
The fixing strength of the nut cannot be influenced, and therefore the anti-loosening performance using face of the nut is wider.
