Abstract

The invention belongs to the technical field of bolts, and particularly relates to an anti-lock fastening part. The anti-lock fastening part comprises a lead screw with a head and an anti-lock nut, and after the fastening part is fastened to the working face through a wrench, a second part plays a supporting role in the position between a first part and the working face; when the fastening part needs to be detached from the working face, the first part and the second part can be detached from the working face together through the wrench; and when the first part and the lead screw with the headare locked, the first part can not rotate to relieve locking through the force torque generated by a torque wrench in the wrench, the second part can be vigorously twisted through an inner hexagonalring in the wrench, supporting of the second part on the position between the first part and the working face is relieved by rotating the second part, strong extrusion force is lost between the firstpart and the working face, therefore, the first part can be easily detached from the lead screw with the head through the wrench, and the locking problem of the fastening part can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of bolts, in particular to an anti-lock fastener. Background technique [0002] At present, fasteners are widely used, and the performance requirements of fasteners are getting higher and higher. Locking screws, anti-lock special fasteners and corrosion-resistant screws are also used where needed. Existing fasteners generally meet the needs of fastening by improving the mechanical properties of the material; the locking of fasteners occurs on stainless steel, aluminum alloy and titanium alloy fasteners, and the metal alloy itself has anti-corrosion properties. When the surface is damaged, a thin oxide layer is formed to prevent further corrosion. When the fastener is locked, the pressure and heat generated between the teeth will destroy and erase the oxide layer in the middle, so that the metal alloy teeth will be directly blocked or sheared, resulting in adhesion, and then the fastener It is completely lo...
