Abstract

The utility model discloses a lock nut, including the lower nut body, the screw hole is established down at the center of the lower nut body, and the up end an organic whole of the lower nut body is connected with thin wall sleeve, its characterized in that: the upper nut body is movably arranged in the thin-wall sleeve, after the upper nut body is arranged in an inner hole of the thin-wall sleeve, the upper nut body is limited by the flanging of the upper port of the thin-wall sleeve, the center of the upper nut body is provided with an upper threaded hole, and the upper nut body and the lower nut body can rotate relatively. The utility model discloses utilize the mutual and tight self-locking function who realizes lock nut of upper and lower nut body that the assembly is in the same place, make the lock nut product can have more reliable fastening locking performance.

Description

Locking nut

Technical Field

The utility model relates to a fastener product, concretely relates to lock nut.

Background

Among nut products of the fastening member, the lock nut is widely used because it has a self-locking function and a simple structure. However, the locknut of the prior art only has a simple anti-loosening function, and the anti-loosening function is inferior to a double-nut tightening mode.

Disclosure of Invention

The utility model aims to provide an utilize the upper and lower nut body's that the assembly is in the same place each other and tightly realize from the locking function, can have the lock nut of more reliable fastening locking performance.

The utility model discloses a through following technical scheme implementation:

lock nut, including the lower nut body, the screw hole is established down at the center of the lower nut body, and the up end body coupling of the lower nut body has thin wall sleeve, its characterized in that: the upper nut body is movably arranged in the thin-wall sleeve, after the upper nut body is arranged in an inner hole of the thin-wall sleeve, the upper nut body is limited by the flanging of the upper port of the thin-wall sleeve, the center of the upper nut body is provided with an upper threaded hole, and the upper nut body and the lower nut body can rotate relatively.

Above-mentioned technical scheme's lock nut, come from the locking function with the mutual and tight realization of the upper and lower nut body of assembly together, go up the nut body and replaced nylon or metal washer among the prior art lock nut, at first carry out the screw thread with the lower nut body when using and screw thread, then will descend the nut body to carry out the screw thread and screw thread, thereby realize lock nut's two nuts and the mode of fastening, make the lock nut product can have more reliable fastening locking performance, also can make two nuts and the tight product of fastening change realization integration and convenient management simultaneously.

Preferably, the upper nut body is positioned at the lower part of the inner hole of the thin-wall sleeve and is a cylinder, the outer diameter of the cylinder is matched with the inner hole aperture of the thin-wall sleeve, and the upper part of the upper nut body, away from the inner hole of the thin-wall sleeve, is an outer hexagon.

Drawings

The utility model discloses there is following figure:

figure 1 is a schematic structural diagram of the present invention,

fig. 2 is a top view in the direction of fig. 1.

Detailed Description

The details and the working principle of the embodiments of the present invention are described in detail below with reference to the accompanying drawings:

as shown in the figure, the locking nut of the utility model comprises a lower nut body 5, the outer edge profile of the lower nut body 5 is an outer hexagon, a lower threaded hole 6 is arranged at the center of the lower nut body 5, the upper end surface of the lower nut body 5 is integrally connected with a thin-wall sleeve 4, an upper nut body 1 is movably arranged in the thin-wall sleeve 4, the lower outer edge profile 42 of the upper nut body 1, which is positioned in the inner hole of the thin-wall sleeve 4, is a cylinder, the outer diameter of the cylinder is matched with the inner hole aperture of the thin-wall sleeve 4, the upper outer edge profile 41 of the upper nut body 1, which is separated from the inner hole of the thin-wall sleeve 4, is an outer hexagon so as to facilitate the wrench to independently screw the upper nut body 1, the upper nut body 1 is limited by the upper port flanging 3 of the thin-wall sleeve 4 after being arranged in the inner hole of the thin-wall sleeve 4, the upper, the upper threaded hole 2 and the lower threaded hole 6 have the same thread size.

Claims
