Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1 to 3, a combined nut with an anti-loose function includes a nut body 1 and a conical elastic washer 2, wherein a support surface at one end of the nut body 1 is provided with a guide step 101, and the conical elastic washer 2 is mounted on an outer diameter edge of the guide step 101;

the scheme has the beneficial effects that: through being provided with direction step 101 in one side of nut main part 1, and install rotatable toper elastic washer 2 along the outer edge of direction step 101, lead to the step 101 to cause plastic deformation through the punching press, direction step 101 deformation zone excircle diameter slightly is greater than toper elastic washer 2 internal diameter, slightly is less than packing ring recess 201 diameter, and reserve certain distance with the packing ring face, make the packing ring rotatable, do not drop, make the device reach installing in of nut and packing ring and embolia comparatively simply conveniently, the packing ring is difficult for losing, the efficiency and the quality of increase work.

Further, the inner diameter of the tapered elastic washer 2 is slightly larger than the diameter of the guide step 101, and the inner diameter of the tapered elastic washer 2 is matched with the outer diameter of the guide step 101;

the inner diameter of the conical elastic washer 2 is slightly larger than the diameter of the guide step 101, and the conical elastic washer 2 is matched with the guide step 101, so that the outer surface of the guide step 101 can be stably sleeved with the conical elastic washer 2, a good anti-loosening function can be achieved after installation is completed, and the conical elastic washer is suitable for occasions with large vibration.
