Abstract

The invention relates to a bolt set with an anti-loosening function. The bolt set comprises a two-section bolt, a pre-tightening nut and an anti-loosening nut. Two threaded sections which are different in diameter are arranged on the two-section bolt, and the rotating directions of the two sections of threads are opposite to each other; the pre-tightening nut is in matched screw joint with the large-diameter threaded section, and the anti-loosening nut is in matched screw joint with the small-diameter threaded section; a groove is formed in the end surface of the pre-tightening nut, a through hole is formed in a position, corresponding to the groove position of the pre-tightening nut, of the anti-loosening nut, a top thread is in screw joint with one end of the through hole, a steel ball is arranged at the other end of the through hole, and a spring is arranged between the steel ball and the top thread. By acting the nuts which are different in pitch and rotating direction on the same bolt and arranging the steel ball and the groove which are matched with each other between the two nuts, a locating role is played after the two nuts are screwed. According to the structure, the two nuts can counteract the vibration quantities of each other under alternating load action and restrict each other in a trend movement direction so as to be self-locked to prevent looseness.

Description

technical field [0001] The invention relates to the field of mechanical installation, in particular to a bolt group with anti-loosening function. Background technique [0002] Bolt is a common part of multi-piece connection and plays a vital role in mechanical connection. However, in the environment of alternating loads, the bolted connection is very easy to loosen, thus losing the connection function, causing the connection to fail and easily causing safety accidents. Contents of the invention [0003] The object of the present invention is to provide a bolt group with anti-loosening function, which is a bolt assembly with self-locking function and independent anti-loosening function. Compared with common bolts, it is safer and more reliable, and has better anti-loosening effect. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A bolt group with an anti-loosening function, comprising two sections of bolts, pr...
