Abstract
The utility model discloses an anti-loosening nut, which belongs to a fastening piece. The anti-loosening nut comprises a nut body, wherein the nut body is provided with an internal thread; a circular boss is arranged on one end face of the nut body; and a plurality of elastic sheets are arranged in an inner hole of the circular boss along the circumferential direction. The anti-loosening nut has the advantage that: a better anti-loosening function can be achieved without arranging any spring gasket.
Description
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of 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 lock nut that spring washer can have better anti-loosing effect at bolt first.
Technical solution of the present utility model is, a kind of lock nut with following structure is provided: comprise nut body, nut body is provided with internal thread, wherein, an end face of nut body is provided with round ring boss, is circumferentially with a plurality of spring sheets in the round ring boss endoporus.
After adopting above structure, compared with prior art, the utility model lock 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 lock nut is provided with round ring boss, is circumferentially with a plurality of spring sheets in the endoporus of round ring boss.After being tightened on the utility model lock nut on the bolt, produce the elastic deformation force thereby resiliently deformable can occur these spring sheets, and tightly pack tightly on the outside thread of bolt, thereby it being loosening to prevent effectively that the utility model lock nut from occuring.
Description of drawings:
Fig. 1 is the perspective view of the utility model lock nut.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model lock nut is described further:
As shown in Figure 1, in this embodiment, the utility model lock nut comprises nut body 1, and nut body 1 is provided with internal thread 3, an end face of nut body 1 is provided with round ring boss 2, is circumferentially with four spring sheets 4 in the endoporus of round ring boss 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.
