Abstract
The utility model provides a self-locking nut, including the nut main part that is equipped with the internal thread hole, be equipped with four bosss on the terminal surface of nut main part, be equipped with on the lateral wall of nut main part with the elongated slot of internal thread hole intercommunication, and the elongated slot equipartition in under the boss. The utility model has simple operation during self-locking and is stable and reliable during locking, when in use, the common nut is firstly screwed, then, when the self-locking nut is screwed, the four bosses on the end surface of the self-locking nut firstly contact the common nut and are stressed, because the long grooves below the bosses belong to weak links, the bosses can deform due to stress, thereby further damaging the local thread pitch of the internal thread of the self-locking nut and finally leading to the locking of the self-locking nut; and the processing is easy, and the batch production can be realized.
Description
Technical Field
The utility model belongs to the technical field of the fastener, concretely relates to self-locking nut.
background
The bolt and the nut are often used for fastening objects, sometimes in order to prevent the nut from loosening, the nut is often added, however, the effect after the nut is added is not good, and the nut loosening condition can also occur. The self-locking nut in the prior art has the disadvantages of very complicated structure, high processing cost, poor loosening effect and unsuitability for batch production.
Disclosure of Invention
In order to solve the problem, the utility model provides a simple structure, locking effectual self-locking nut.
In order to achieve the purpose, the utility model adopts the technical scheme that:
A self-locking nut comprises a nut main body provided with an internal thread hole, wherein four bosses are arranged on the end face of the nut main body, long grooves communicated with the internal thread hole are arranged on the side wall of the nut main body, and the long grooves are uniformly distributed under the bosses.
Furthermore, an elongated slot is arranged right below each boss.
Further, the height of the boss is slightly smaller than the width of the long groove, and the distance from the long groove to the end face of the nut body is smaller than or equal to two times the height of the boss.
further, the top surface and the side edges of the boss are excessively connected through a circular arc.
Further, the slotting direction of the long slot is perpendicular to the axis of the nut body.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. the utility model discloses be equipped with the boss on the terminal surface of nut main part, be equipped with the elongated slot under the boss, when using, screw up ordinary nut at first, afterwards, when screwing up self-locking nut, four bosses on the self-locking nut terminal surface contact ordinary nut and atress at first, because the elongated slot below the boss belongs to the weak link, can warp because of the atress of boss, and then lead to destroying the internal threaded local pitch of self-locking nut, finally lead to the locking of self-locking nut;
2. the utility model discloses easy operation during auto-lock, reliable and stable during locking, processing is easy moreover can batch production.

FIG. 2 is a side view of the present invention;
Fig. 3 is a usage state diagram of the present invention.
Detailed Description
As shown in fig. 1-3, a self-locking nut includes a nut main body 1 having an internal threaded hole, four bosses 2 are provided on an end surface of the nut main body 1, elongated slots 3 communicated with the internal threaded hole are provided on a side wall of the nut main body 1, and the elongated slots 3 are uniformly distributed right below the bosses 2.
An elongated slot 3 is arranged right below each boss 2.
The height of the boss 2 is slightly smaller than the width of the long groove 3, and the distance from the long groove 3 to the end face of the nut body 1 is smaller than or equal to two times the height of the boss 2.
The top surface and the side edge of the boss 2 are connected in transition through an arc.
The slotting direction of the long slot 3 is vertical to the axis of the nut body 1.
When the nut body 1 is used, the fastened object 5 is fixed on the screw 7 through the common nut 4, the gasket 6 is installed afterwards, one side of the gasket 6 is a plane and is attached to the common nut 4, the other side of the gasket 6 is matched with the end face contour of the nut body 1 with the boss 2, and finally the nut body 1 is installed.
Claims (5)
1. The self-locking nut comprises a nut main body provided with an internal thread hole, and is characterized in that four bosses are arranged on the end face of the nut main body, long grooves communicated with the internal thread hole are formed in the side wall of the nut main body, and the long grooves are uniformly distributed right below the bosses.
