Abstract

The invention discloses a reverse thread anti-loosening tight locking bolt. The bolt comprises a bolt body pipe, the bolt body pipe comprises an anti-skid piece and a pipe body, a first thread is formed in the outer side wall of the end, away from the anti-skid piece, of the pipe body, a locking piece is installed at the position, located at the first thread, of the pipe body, a plurality of lockholes are annularly formed in the locking piece at equal intervals, a second thread is formed in the inner wall of the pipe body, a hexagonal threaded rod is inserted into the pipe body through the second thread, and a nut and a lock disc are installed at two ends of the hexagonal threaded rod respectively. Through the first thread and the second thread, the rotating direction of the locking pieceand the rotating direction of the hexagonal threaded rod installed on the bolt body pipe are opposite, then reverse interlocking of the locking piece and the hexagonal threaded pipe is realized, meanwhile, the locking piece and the hexagonal threaded rod rotate consistently through the locking disc, then the locking piece and the hexagonal threaded rod can only rotate in an interlocking mode, thus the locking reliability of the bolt is improved, and the bolt is effectively prevented from loosening.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a reverse thread anti-loosening tight locking bolt. Background technique [0002] In engineering construction, it is often necessary to lock and fix two connecting parts, and commonly used locking and fixing parts are usually locked by bolts. [0003] The existing bolt locking uses structures such as screws, nuts, and gaskets to jointly lock the connecting parts to increase the tightness of the connection and avoid falling off. Relative rotation occurs, causing the nut to loosen, thereby causing the connecting piece to loosen, which is likely to cause engineering accidents. Contents of the invention [0004] The object of the present invention is to solve the defect in the prior art that there is relative rotation and looseness between the nut and the screw due to the state of use, and proposes a reverse thread anti-loosening tight locking bolt. [0005] In order to ac...
