Abstract
The utility model discloses a kind of anti-loose threaded joint assemblies, including first joint and second joint;Threaded column is equipped on the first joint, threaded hole is equipped on the second joint with the threaded column cooperation, it is characterized by: the depth of threaded hole is less than the length of the threaded column, so that the first joint and second joint are screwed in place, threaded column forms a section of exposed reserved thread section;Reserved thread section is screwed with a anti-loose piece, anti-loose piece can be axially moved relative to the threaded column;When the anti-loose piece moves to predetermined position along the axial direction towards the second joint, second joint is pressed, so as to limit the looseness of the second joint relative to the threaded column;The utility model can realize double anti-loose mechanism by the threaded cooperation of first joint and second joint, and reserved thread section cooperation anti-loose piece, effectively solve the problem of joint loosening due to vibration.
