Description

Nut

Technical field:

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

Background technique:

Nut usually and bolt, 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 match with bolt frictional force between the screw thread of nut, 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 to put spring washer at bolt first and namely have the preferably nut of anti-loosing effect.

Technical solution of the present utility model is, a kind of nut with following structure is provided: comprise nut body, nut body is provided with tapped through hole, wherein, an end face of nut body is provided with annular boss, is provided with annular groove near the annular boss place on the perisporium of tapped through hole.

After adopting above structure, compared with prior art, the utility model nut has the following advantages: to rely in use spring washer to carry out locking different from common nut, because an end face of the nut body of the utility model nut is provided with annular boss, be provided with annular groove near the annular boss place on the perisporium of tapped through hole, when the locking component, an end that has annular boss on the nut screws in first on the bolt, nut body between annular boss and the annular groove is deformed, thereby nut thread herein is pressed on the thread of bolt, prevented the loosening of nut, therefore, the utility model nut does not need to use spring washer namely to have preferably anti-loosing effect.

Description of drawings:

Fig. 1 is that the master of the utility model nut looks the sectional structure schematic diagram.

Embodiment:

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

As shown in Figure 1, in this embodiment, the utility model nut comprises nut body 1, and nut body 1 is provided with tapped through hole 2, an end face of nut body 1 is provided with annular boss 3, is provided with annular groove 4 near annular boss 3 places on the perisporium of tapped through hole 2.

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)
