Abstract
The utility model relates to a locking nut and belongs to a fastener. The locking nut comprises a nut body, wherein a threaded through hole is formed on the nut body; a plurality of elastic sheets are distributed at one end of the nut body circumferentially and uniformly; the inner wall of each the elastic sheet is provided with internal thread as same as the thread in the threaded through hole; and the free end of each elastic sheet is inclined towards the center of the threaded through hole. The utility model has the advantage that the locking nut has good locking function without the need of a spring washer.
Description
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of anti-loose lock nut.
Background technique:
Nut usually and bolt, screw fit is used the effect that connects fastening component of playing, when using common nuts and bolt 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 to provide a kind of the needs to put the anti-loose lock nut that spring washer can have better anti-loosing effect at bolt first.
Technical solution of the present utility model is, provide a kind of anti-loose lock nut with following structure: comprise nut body, nut body is provided with tapped through hole, wherein, one end of nut body circumferentially is evenly equipped with a plurality of spring sheets, the inwall of spring sheet is provided with the internal thread identical with screw thread in the tapped through hole, and the free end of spring sheet is centroclinal to tapped through hole.
After adopting above structure, compared with prior art, the utility model anti-loose lock nut has the following advantages: to rely in use spring washer to carry out locking different from common nut, because an end of the nut body of the utility model anti-loose lock nut circumferentially is evenly equipped with a plurality of spring sheets, the inwall of spring sheet is provided with the internal thread identical with screw thread in the tapped through hole, and the free end of spring sheet is centroclinal to tapped through hole.After being tightened on the utility model anti-loose lock nut on the bolt, thereby the free end of these spring sheets can open the generation elastic deformation force, and tightly packs tightly on the outside thread of bolt, thereby it is loosening to prevent effectively that the utility model anti-loose lock nut from occuring.
Description of drawings:
Fig. 1 is the perspective view of the utility model anti-loose lock nut.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model anti-loose lock nut is described further:
As shown in Figure 1, in this embodiment, the utility model anti-loose lock nut comprises nut body 1, nut body 1 is provided with tapped through hole 2, one end of nut body 1 circumferentially is evenly equipped with four spring sheets 3, the inwall of spring sheet 3 is provided with the internal thread 4 identical with screw thread in the tapped through hole 2, and the free end of spring sheet 3 is centroclinal to 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.
