1. The utility model provides an elastic deformation lock nut, includes nut (1) be equipped with internal thread hole (11) on nut (1), its characterized in that: the nut is characterized by further comprising a plurality of inner hexagon screws (2), a plurality of side threaded holes (12) are formed in the periphery of the nut (1), and the inner hexagon screws (2) are connected in the side threaded holes (12) in the periphery of the nut (1) through threads.

2. An elastically deformable lock nut as claimed in claim 1, wherein: the distance (L) between the bottom surface of each side threaded hole (12) and the bottom surface of the triangular tooth groove of the internal threaded hole (11) is 0.15mm to 0.3 mm.

Technical Field

The invention relates to a fastener, in particular to an elastic deformation lock nut.

Background

In the fastening piece of the threaded connection, in order to lock the nut, a set screw is adopted, the structure is easy to damage thread teeth on the screw rod, a tongue turning washer is adopted, a locking nut and other structural forms are adopted, but the structures are relatively complex and the structural size is relatively large.

Disclosure of Invention

The invention aims to provide an elastic deformation locking nut which is novel in structure, quick in locking, reliable in work and long in service life.

In order to achieve the purpose, the invention comprises a nut, a plurality of inner hexagon screws and a plurality of outer hexagon screws, wherein the nut is provided with an inner thread hole; the distance between the bottom surface of each side thread hole and the bottom surface of the triangular tooth groove of the inner thread hole is 0.15 mm-0.3 mm.

According to the invention, as the plurality of side thread holes are arranged on the periphery of the nut, the hexagon socket head cap screws are arranged in the side thread holes on the periphery of the nut, and the distance between the bottom surface of each side thread hole and the bottom surface of the triangular tooth groove of the internal thread hole is 0.15 mm-0.3 mm, when the nut is arranged on the screw rod, the metal layer between the bottom surface of the side thread hole and the bottom surface of the triangular tooth groove of the internal thread hole can be elastically deformed to hold the screw rod only by screwing the hexagon socket head cap screws, so that the purpose of locking the nut is achieved, and when the hexagon socket head cap screws are loosened, the elastic deformation of the metal layer between the bottom surface of the side thread hole and the bottom surface of the triangular tooth groove of the internal thread hole can be quickly eliminated. The invention has novel structure, quick locking, reliable work and long service life.
