Assembly parts of nut washer

Abstract

The invention is the nut gasket assembly, which comprises the nut and the gaskets. One side of the nut has the wedge slopes that are equiangular arranged with one side higher than the other, and the jointing places of the slopes form the blocking surfaces with fall; the center of the gasket has the through-hole, one side of the gasket forms the continuous slope corresponding to the wedge slope, and the jointing places of the continuous slopes from the carrying faces with the fall; the other sides of the gaskets have a plurality of sharp recesses that have the facade and the slope, and the push-sloping direction of the slope is as the same as that of the continuous slopes. The circumvent of the wedge slopes extend outside to form the flange face, and the lower part of the flange forms the column ring matching with the central hole of the gasket. The nut and the gasket trig and the outer surface and the sharp recess joint, which takes the effects of loosing prevention and theft guarding.

Description

technical field [0001] The invention relates to a fastener, in particular to a nut washer assembly consisting of a nut and a washer. Background technique [0002] At present, nuts and washers are usually combined with bolts to form fastening components. They are widely used in real life as structural connectors. The solid structure is that bolts are interspersed in the connecting piece, the other end of the bolt is put on a washer, and it is tightened and fixed through the threaded connection of the nut and the bolt. Since the structure of the above nut and the washer is relatively simple, they cooperate with the bolt only through a simple The threaded connection plays a fixed role, so under the impact of high temperature or high-frequency vibration, it is easy to cause the thread slopes between the nuts and bolts to slide against each other, causing the nuts and bolts to rotate in the direction of loosening, so that the bolts and nuts loosen. The nut is loose or falls off,...

Problems solved by technology

[0002] At present, nuts and washers are usually combined with bolts to form fastening components. They are widely used in real life as structural connectors. The solid structure is that the bolts are inserted into the connectors, the other end of the bolts is put on a washer, and it is tightened and fixed through the threaded connection of the nut and the bolt. Since the structure of the above-mentioned nuts and washers is relatively simple, they cooperate with the bolts only through a simple The threaded connection plays a fixed role, so under the impact of high temperature or high-frequency vibration, it is easy to cause the thread slopes between the nuts and bolts to slide against each other, causing the nuts and bolts to rotate in the direction of loosening, so that the bolts and nuts loosen. The nut is loose or falls off, which is prone to serious accidents

In addition, with this simple matching structure, the nut is easily disassembled by others with simple tools, which cannot effectively prevent theft and has no anti-theft function.
