Abstract

The invention discloses an anti-loose locking method and a never-loose bolt. The never-loose bolt includes a bolt head and a screw which is connected with the bolt head as a whole. The screw consistsof a right-hand thread section and a left-hand thread section which is connected with the right-hand thread section, and the diameter of the right-hand thread section is greater than the diameter of the left-hand thread section; and the right-hand thread section is connected with a right-hand thread nut in a threaded mode, the left-hand thread section is connected with a left-hand thread nut in athreaded mode, and the right-hand thread nut and the left-hand thread nut are movably connected together to form a conjoined nut which can rotate relatively but cannot be separated. According to the anti-loose locking method and the never-loose bolt, the mutual containment and mutual blocking actions of the conjoined nut are adopted to achieve the purpose of looseness prevention and locking. Not only is the assembly convenient, but also the used screws and nuts are not damaged, the screws and the nuts can still be used continuously, and the cost is saved.

Description

technical field [0001] The invention relates to a bolt anti-loosening and locking method and a never-loosening bolt, belonging to the technical field of fasteners. Background technique [0002] Bolt is a commonly used fastener, widely used in various mechanical and electrical equipment. For general applications, there are no particularly strict requirements on the anti-loosening properties of the bolts. However, for the fields of automobiles, aviation, aerospace, and nuclear power plants, many equipment or components work in a vibrating environment for a long time, and the bolts and nuts are prone to loosening, which affects the normal operation of the equipment and even causes security incident. [0003] In order to solve the problem of bolt anti-loosening, various self-locking nuts have appeared in the existing fastener industry, which have complex structures, high production costs, inconvenient installation, and unsatisfactory anti-loosening effects. In addition, the w...
