The novel anti-theft and anti-loosening bolt and nut set comprises a bolt, a nut and an elastic locking piece, the elastic locking piece is arranged in the nut, and the bolt is connected with the nut in a meshed mode; and the bolt comprises a head part and a screw rod, the screw rod is arranged on the bottom wall of the head part, locking grooves are evenly formed in the circumferential side wall of the screw rod at intervals, the head part is arranged in a hexagonal shape, and the screw rod is cylindrical. The invention belongs to the technical field of bolts and nuts, and particularly relates to the novel anti-theft and anti-loosening bolt and nut set, the elastic locking piece is additionally arranged to prevent the nut from reversing and loosening, a good effect is achieved, great cost does not need to be increased, the structure is ingenious and reliable, and the problem that the effect of bolts and nuts in the current market is poor is effectively solved.

Description

Technical field [0001] The invention belongs to the technical field of bolts and nuts, and specifically refers to a new type of anti-theft and anti-loosening bolt and nut set. Background technique [0002] The anti-loosening and anti-theft methods of bolts and nuts used today mainly use the method of increasing friction to prevent loosening. Of course, there are also some commonly used anti-loosening and anti-theft methods that change their structures to prevent loosening and anti-theft, such as using cotter pins. , series wires and stop washers, etc. This method makes disassembly inconvenient. Contents of the invention [0003] In view of the above situation, in order to overcome the shortcomings of the existing technology, the present invention provides a new type of anti-theft and anti-loosening bolt and nut set, which adds an elastic locking piece to prevent the nut from being reversed and loosened and anti-loosened. It achieves good results and does not need to be ad...
