A high-strength anti-loosening nut

Abstract

The invention belongs to the technical field of hardware parts, and in particular relates to a high-strength anti-loosening nut, which includes a first nut and a second nut; the end of the first nut opposite to the contact object is the contact end, and the end facing away from the object is the connection end. A limiting ring is arranged on the connecting end, and a notch is opened on the limiting ring along the axial direction to make it partially deformed after being subjected to an external force, and this part forms a deformable part; the inner wall of the second nut port is provided with a first assembly groove , the inner wall of the first assembly groove is provided with a protruding part, after the second nut is sleeved on the limit ring, the protruding part in the first assembly groove presses the outer wall of the deformable part of the limit ring, and makes the deformable part move towards inner contraction. The present invention divides it into a first nut and a second nut, wherein the first nut is a fastening nut in direct contact with the fixed object, and the second nut is an anti-loosening nut, which is pressed against the first nut. Under the action, the rotation of the first nut can be effectively prevented, thereby ensuring the stability of the fixed object.

Description

technical field [0001] The invention belongs to the technical field of hardware parts, in particular to a high-strength anti-loosening nut. Background technique [0002] Nuts and bolts are a widely used mechanical fastener. When the usual nuts and bolts cooperate to fix the mechanical parts, due to the movement or vibration of the machine, the nuts are easy to loosen and fall off for a long time, causing the fixed parts to shift or loosen. malfunction or accident. [0003] In order to solve the problem of nut loosening, people have designed many anti-loosening nuts or devices according to different application conditions and environments, such as combined nuts, which include nuts and outer rings, and the outer rings are sandwiched between the nut and the fastened Objects are threaded together on the screw rod, the nut and the axial end of the outer ring are sleeved and riveted together, and the outer ring and the nut can rotate relative to each other. In this combined nut,...

[0003] In order to solve the problem of nut loosening, people have designed many anti-loosening nuts or devices according to different application conditions and environments, such as combined nuts, which include nuts and outer rings, and the outer rings are sandwiched between the nut and the fastened Objects are threaded together on the screw rod, the nut and the axial end of the outer ring are sleeved and riveted together, and the outer ring and the nut can rotate relative to each other. In this combined nut, the nut and the outer ring can rotate relatively. It solves the phenomenon that when the bolt assembly is tightened, the nut is easy to scratch the surface of the fastened object; but this combined nut does not solve the problem that the nut is easy to loosen and fall off, and the loose nut is easy to make the combined nut The force is not uniform, resulting in a large shear force on the bolt assembly, resulting in damage to the outer ring and shortening the service life of the combined nut
