[0023] Please refer to Figure 1 and Figure 2 A metal locking nut;

[0024] It comprises: a nut body 1, a loosening prevention assembly is mounted at the bottom of the nut body 1, the loosening prevention assembly is used for preventing the nut body 1 from loosening during use, and the loosening prevention assembly comprises a connecting groove 9, a connecting spring 10 and an anti-loosening disc 8; the connecting groove 9 is arranged at the bottom of the two sides of the nut body 1, the connecting spring 10 is mounted in the connecting groove 9, the bottom end of the connecting spring 10 is provided with the anti-loosening disc 8, and the anti-loosening disc 8 is located at the bottom of the nut body 1;

[0025] The nut body 1 is screwed on the outside of the screw rod 2, and is screwed together with the screw rod 2 to play a fastening role. In order to make the nut body 1 more firm after being screwed, the anti-loosening assembly is installed on the nut body 1. When the nut body 1 is rotated, the anti-loosening disc 8 in the anti-loosening assembly is attached to the bottom of the nut body 1 under the limiting of the connecting rod 5. The connecting groove 9 provides installation space for the connecting spring 10. At this time, the connecting spring 10 is compressed into the inside of the connecting groove 9. After the nut body 1 is screwed, the connecting rod 5 is no longer limited, so that the anti-loosening disc 8 can apply downward pressure under the downward elastic force of the connecting spring 10, thereby generating upward thrust on the nut body 1, so that the inside thread of the nut body 1 and the thread on the screw rod 2 are more closely and strongly rubbed, so that the stability between the nut body 1 and the screw rod 2 is higher, and the nut body 1 cannot be easily loosened. If the nut body 1 needs to be removed, only a larger rotating force is needed to easily disassemble the nut body 1.

[0026] Please refer to Figure 1 、 Figure 3 and Figure 4 , a metal anti-loosening nut;

[0027] The top of the nut body 1 is provided with an installation groove 3, and the installation groove 3 penetrates the bottom of the nut body 1. The top of the installation groove 3 is symmetrically provided with a corresponding groove 4 on both sides. The connecting rod 5 is slidably installed in the inside of the installation groove 3, and the bottom end of the connecting rod 5 is connected with the top of the anti-loosening disc 8. The top end of the connecting rod 5 is rotatably installed with a rotating disc 6. The outside of the rotating disc 6 is symmetrically installed with a limiting plate 7. The inside of the nut body 1 is threadedly connected with a screw rod 2.

[0028] The installation groove 3 provides space for the installation of the connecting rod 5. The connecting rod 5 provides a position for the installation of the rotating disc 6. When the anti-loosening disc 8 needs to be attached to the bottom of the nut body 1, the anti-loosening disc 8 is pushed upward and attached to the bottom of the nut body 1. After that, the rotating disc 6 is located above the installation groove 3. By rotating the rotating disc 6, the limiting plate 7 is staggered with the corresponding groove 4. The anti-loosening disc 8 can be positioned at the bottom of the nut body 1 through the connecting rod 5. When the anti-loosening disc 8 needs to be used, the rotating disc 6 is rotated so that the limiting plate 7 corresponds to the corresponding groove 4. The connecting rod 5 is no longer limited, so that the anti-loosening disc 8 can move downward to apply pressure.

[0029] Working principle, first push the anti-loosening disc 8 upward on the bottom of the nut body 1, and make the anti-loosening disc 8 not move downward under the elastic force of the connecting spring 10 through the limiting of the connecting rod 5. The nut body 1 is rotatably installed on the outside of the screw rod 2. After the nut body 1 is fastened, rotate the rotating disc 6 so that the limiting plate 7 corresponds to the corresponding groove 4, so that the connecting rod 5 is no longer limited, so that the anti-loosening disc 8 can move downward to apply pressure, so that the nut body 1 at the top and the screw rod 2 are more stable.

[0030] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the application can be implemented in other particular forms without departing from the spirit or essential characteristics of the application. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No feature of the application is considered critical unless it is expressly stated in the claims.
