Description

Technical Field

[0001] The utility model relates to the field of locking nuts, and particularly relates to a locking nut with an embedded iron sheet. Background Art

[0002] A locking nut is a nut widely used in industries such as machinery. Its working principle is to lock itself by using the friction between the nut and the bolt. However, the reliability of this self-locking will decrease under dynamic loads. In some important occasions, some anti-loosening measures will be taken to ensure the reliability of the nut locking.

[0003] However, for the existing locking nut with an embedded iron sheet, during multiple disassembly and assembly processes, the iron sheet is prone to deformation. Once deformation occurs, it not only affects the overall use and locking effect, but also is not convenient to replace the iron sheet alone.

[0004] Therefore, it is very necessary to invent a locking nut with an embedded iron sheet that is convenient for replacing the iron sheet. Summary of the Utility Model

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model for a locking nut with an embedded iron sheet is as follows: A locking nut with an embedded iron sheet includes a hexagonal cap and an iron sheet locking ring. Among them: A threaded hole is penetrated through the surface of the hexagonal cap, and an iron sheet locking ring is detachably and fixedly installed inside one end of the hexagonal cap, and the iron sheet locking ring is communicated with the threaded hole; A plurality of inner limiting grooves are evenly distributed in a circular array on the surface of the threaded hole inside the hexagonal cap; A plurality of barb elastic cards corresponding to the inner limiting grooves are evenly fixed and installed on one side surface of the iron sheet locking ring in a circular array, and the barb elastic cards are in the corresponding inner limiting grooves, and the barb of the barb elastic card is clamped with the hexagonal cap.

[0006] Preferably, an outer ring cavity is opened at one end of the hexagonal cap, and an inner ring cavity is opened at the other end of the hexagonal cap. Both the outer ring cavity and the inner ring cavity are communicated with the threaded hole; The iron sheet locking ring is installed in the outer ring cavity; The barb of the barb elastic card is in the inner ring cavity; The diameters of the outer ring cavity and the inner ring cavity are larger than the diameter of the threaded hole.

[0007] Preferably, a plurality of outer limiting grooves are evenly distributed on the outer side of one end of the hexagonal cap, and the outer limiting grooves are on the same side as the outer ring cavity, and the outer limiting grooves are communicated with the outer ring cavity; The iron sheet locking ring is clamped with the outer limiting grooves.

[0008] Preferably, a plurality of blocks corresponding to the outer limiting grooves are evenly fixed and installed on the circumferential surface of the iron sheet locking ring in a circular array, and the blocks are stuck in the corresponding outer limiting grooves.

[0009] Compared with the prior art, the advantages of the utility model are as follows:

[0010] In the overall setting of the present utility model, during the use process, when the iron sheet locking ring is severely deformed and the overall locking force cannot be guaranteed, the iron sheet locking ring can be replaced independently, making the overall use process more convenient and flexible.

At the same time, after the hexagonal cap 1 is connected to a bolt through the threaded hole 2, the strength between the iron sheet locking ring 7 and the hexagonal cap 1 can be improved by the extrusion force of the bolt, and the barb elastic cards 8 are prevented from loosening from the hexagonal cap 1. The barb of the barb elastic card 8 is clamped with the hexagonal cap 1, so as to ensure the firmness between the iron sheet locking ring 7 and the hexagonal cap 1 and prevent loosening between the iron sheet locking ring 7 and the hexagonal cap 1.
