Description

Locking nut

Technical field:

The utility model relates to a kind of fastening piece, specifically is a kind of locking nut.

Background technique:

Common and the bolt of nut, screw fit is used the effect that connects fastening component of playing, when using screw bolt and nut to lock component, in order to prevent the loosening of nut, general after bolt puts spring washer, again nut being tightened on the bolt first, rely on the elastic force of spring washer to increase nut and the frictional force between the component of being locked, and then prevent the loosening of nut, although this method can well play the effect of nut anti-looseness, but also there is a deficiency, that is exactly before screwing on nut, to put spring washer at bolt first, use so just cumbersome.

The model utility content:

The technical problems to be solved in the utility model is, providing a kind of does not need first to put spring washer at bolt and can prevent preferably the locking nut that becomes flexible.

Technical solution of the present utility model is, a kind of locking nut with following structure is provided: comprise nut body, nut body is provided with tapped through hole, wherein, the left end of nut body is provided with the disk coaxial with tapped through hole, is evenly equipped with a plurality of boss on the left side of disk.

After adopting above structure, compared with prior art, the utility model locking nut has the following advantages: because the left end of the nut body of the utility model locking nut is provided with the disk coaxial with tapped through hole, be evenly equipped with a plurality of boss on the left side of disk, after screwing the utility model locking nut, a plurality of boss on the disk left side can tightly be pressed on the component that are locked, frictional force between the component that increased the utility model locking nut and be locked, therefore, the utility model locking nut has and prevents preferably the function become flexible.

Description of drawings:

Fig. 1 is the perspective view of the utility model locking nut.

Embodiment:

Below in conjunction with the drawings and specific embodiments the utility model locking nut is described further:

As shown in Figure 1, in this embodiment, the utility model locking nut comprises nut body 1, and nut body 1 is provided with tapped through hole 2, the left end of nut body 1 is provided with the disk 3 coaxial with tapped through hole 2, is evenly equipped with a plurality of boss 4 on the left side of disk 3.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.

Claims (1)

1. locking nut, comprise nut body (1), described nut body (1) is provided with tapped through hole (2), it is characterized in that: the left end of described nut body (1) is provided with the disk (3) coaxial with tapped through hole (2), is evenly equipped with a plurality of boss (4) on the left side of described disk (3).
