Abstract

The invention relates to the field of mechanical fasteners, and discloses an anti-loose connecting bolt assembly. The anti-loose connecting bolt assembly comprises a first bolt, a fastening nut and asecond bolt. A first thread is arranged on the outer side of a threaded rod of the first bolt, and a first screw hole is formed in the interior of the threaded rod in a penetrating mode. A second thread is arranged on the inner side of the first screw hole, and the directions of the first thread and the second thread are opposite. The first thread is matched with a thread of the fastening nut, anda first end of the fastening nut is provided with a first tapered structure. A third thread is arranged on a threaded rod of the second bolt, and the third thread is matched with the second thread. The head portion of the second bolt is provided with an anti-loose structure, the anti-loose structure is a hollow structure, and the edge of the end portion of the hollow structure is provided with asecond tapered structure matched with the first tapered structure. The anti-loose connecting bolt assembly realizes two-way threaded fastening, and meanwhile, by utilizing the fastening nut being in contact with the tapered structure of the second bolt, the problem of screwing outward and loosing of the fastening nut is solved. The anti-loose connecting bolt assembly is reasonable in design, simple in structure, good in fastening performance, and convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of mechanical fasteners, in particular to an anti-loosening connecting bolt assembly. Background technique [0002] Bolts or screw components are used to fasten components. If the fastened object is loose, it will have serious consequences. For example, the loose bolt connection of transmission mechanisms such as airplanes, rails, and machine tools will lead to serious accidents. Therefore, preventing the loosening of connecting components has always been a subject of research. There are many reasons for the loosening of nut bolts, such as in the case of strong vibration, or due to alternating loads or high operating temperature changes, due to changes in the shape of bolts and fasteners, the positive pressure on the friction surface of the nut is reduced. Or disappear, resulting in a loosening torque on the friction surface that drives the nut to rotate to the loosening side, causing the nut to loosen. At...
