Abstract
The utility model discloses a self-locking nut, comprising a nut body, a strip groove and a threaded hole, wherein, the strip groove is arranged on the side surface of the nut body, and the threaded hole is arranged on the upper surface of the nut body; and the threaded hole passes through the strip groove. In the self-locking nut, a bolt is used to pass through the threaded hole, and the upper side part of the strip groove in the self-locking produces deformation by exerting a certain tightening torque, so that the threads of the self-locking nut also produce corresponding deformation to prevent the nut from loosening.
Description
Technical field
The utility model relates to a kind of nut, relates in particular to a kind of nut with auto-lock function.
Background technique
In the prior art, nut is very extensive in the application in each field.General nut only has certain locking function, and in use owing to vibration waits certain reason, its locking function is weakened, and is easily loosening, thereby causes occurring the consequence that is difficult to expect.The various nuts that become flexible of preventing have also appearred in practice, or with other method to nut lock, locking, but the part method is too complicated, or cost is too high.
Therefore, providing self-locking nut a kind of simple in structure, convenient and reliable, with low cost is the technical problem of being badly in need of solution now.
The model utility content
The purpose of this utility model is, at the loosening easily defective of nut in the prior art, provides a kind of and can prevent to become flexible, simple in structure, easy to process and self-locking nut that cost is low.
The utility model provides a kind of self-locking nut to comprise: nut body, offer bar-shaped trough at described nut body side surface, and offer tapped hole at described nut body upper surface, described tapped hole passes described bar-shaped trough.
Self-locking nut of the present utility model uses screw to pass tapped hole, by applying certain screw-down torque, make the upper portion of bar-shaped trough in the self-locking nut produce distortion, thereby make the thread of self-locking nut also produce corresponding distortion, reach the purpose that stops nut loosening.And this self-locking nut is simple in structure, easy to process and with low cost.
Description of drawings
Fig. 1 is the plan view of the utility model self-locking nut;
Fig. 2 is the sectional view of the utility model self-locking nut;
Fig. 3 is the plan view of the utility model self-locking nut;
Fig. 4 is the stereogram of the utility model self-locking nut.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-nut body; The 2-counter sink; The 3-bar-shaped trough; The 4-tapped hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Self-locking nut as shown in Figures 1 to 4 comprises nut body 1; Offer bar-shaped trough 3 at described nut body side surface, nut body 1 upper surface offer tapped hole 4, tapped hole 4 passes described bar-shaped trough.The upper end portion of tapped hole 4 is provided with counter sink 2, and the center line of tapped hole 4 is coaxial with the center line of counter sink 2, and contraposition mutually.
In the present embodiment, bar-shaped trough 3 can be 1/4 to 1/3 of described nut body 1 thickness with the distance of nut body 1 upper surface.Preferably, bar-shaped trough 3 circumferentially is provided with along nut body 1, and the line at the two ends of described bar-shaped trough 3 is by the center of described nut body 1.
Use sunk screw to pass counter sink 2 and tapped hole 4,, make the upper portion of bar-shaped trough 3 in the self-locking nut produce distortion, thereby make the thread of self-locking nut also produce corresponding distortion, reach the purpose that stops nut loosening by applying certain screw-down torque.
Self-locking nut of the present utility model is on the basis of the original simple locking function of nut, by simple modifications such as processing bar-shaped trough, counter sink and tapped holes, make it have the function that prevents nut loosening, and simple in structure, processing is with low cost and easy to use easily.
It should be noted that: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification is illustrated the utility model with reference to above-mentioned example,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
Claims (4)
