The self-locking nut based on the prior double nut type has the following defects: after the existing double nuts which are separated vertically and independently are locked on the bolts, the nuts are gradually loosened by the respective threads due to vibration, so that the problem of unstable thread locking is solved. For this purpose, we propose an integral self-locking nut.

The utility model provides an integral type self-locking nut, includes nut mechanism and last nut mechanism down, nut mechanism screw thread integration sets up in last nut mechanism bottom down, nut mechanism includes down nut, external screw thread joint, a internal thread and draw-in groove down, the fixed external screw thread joint that is provided with in nut top down, go up nut mechanism and include nut, b internal screw thread, internal screw thread interface and wedge fixture block.
Further, an internal thread is formed in the external threaded connector and the lower nut, and a clamping groove is formed in one side, far away from the external threaded connector, of the top of the lower nut.
Further, the inner top of the upper nut is provided with a b internal thread, and the inner bottom of the b internal thread in the upper nut is provided with an internal thread interface corresponding to the external thread joint.
Further, a wedge-shaped clamping block corresponding to the clamping groove is fixedly arranged at the bottom of the upper nut.
Further, the bottom of the upper nut is integrally connected with the external thread joint of the lower nut through an internal thread interface.
Compared with the prior art, the utility model has the following beneficial effects: the self-locking nut is characterized in that a self-locking nut with a set of threads integrally connected is provided for a threaded riveting installer through a component consisting of the lower nut mechanism and the upper nut mechanism, and the nut has higher friction resistance after being screwed tightly on the threads of the bolt through friction force between three groups of threads and clamping connection of the wedge-shaped clamping blocks to the clamping grooves, so that a self-locking effect of difficult loosening is realized, and the problem that after the existing double nuts which are independently separated from top to bottom are locked on the bolts, the nuts are gradually loosened in threads respectively due to vibration, and the locking of the threads is unstable is solved.

Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
As shown in fig. 1-5, an integral self-locking nut comprises a lower nut mechanism 1 and an upper nut mechanism 2, wherein threads of the lower nut mechanism 1 are integrally arranged at the bottom of the upper nut mechanism 2, the lower nut mechanism 1 comprises a lower nut 101, an external threaded joint 102, an internal thread 103 and a clamping groove 104, the top of the lower nut 101 is fixedly provided with the external threaded joint 102, and the upper nut mechanism 2 comprises an upper nut 201, an internal thread 202, an internal threaded interface 203 and a wedge-shaped clamping block 204.
Wherein, an internal thread 103 is arranged in the external thread joint 102 and the lower nut 101, and a clamping groove 104 is arranged at one side of the top of the lower nut 101 far away from the external thread joint 102.
Wherein, the top in the upper nut 201 is provided with a b internal thread 202, and the bottom in the upper nut 201, which is located at the b internal thread 202, is provided with an internal thread interface 203 corresponding to the external thread joint 102.
The bottom of the upper nut 201 is fixedly provided with a wedge-shaped clamping block 204 corresponding to the clamping groove 104.
Wherein, the bottom of the upper nut 201 is integrally connected with the external thread joint 102 of the lower nut 101 through the internal thread interface 203.
It should be noted that, the present utility model is an integral self-locking nut, when in operation, a person screws the lower nut mechanism 1 and the upper nut mechanism 2 which form the self-locking nut based on the threaded integration connection of the internal threaded interface 203 and the external threaded joint 102 into the bolt, at this time, the top surface of the lower nut mechanism 1 is not completely attached to the ground of the upper nut mechanism 2, after the lower nut mechanism 1 is screwed down and cannot continue to rotate, the person screws down the upper nut mechanism 2 alone through a wrench, so that the upper nut mechanism 2 screws down the lower nut mechanism 1, and simultaneously, the wedge-shaped clamping block 204 at the bottom of the upper nut 201 clamps into the clamping groove 104 of the lower nut 101, at this time, the upper nut 201 and the lower nut 101 respectively screw down, and at this time, the upper nut 201 also screws down the lower nut 101 based on the clamping of the wedge-shaped clamping block 204 to the clamping groove 104, so that the upper nut 201 cannot separate from the lower nut 101, thereby realizing three-section thread locking of the bolt, having three-section thread friction force, and effectively guaranteeing the thread locking effect.
