Abstract
A self-locking nut with tight-riveted edge comprises a nut body and a taper locking edge, wherein screw threads in the taper locking edge are in an oval shape and screw threads in a nut body hole are standard screw threads. The lower portion of the nut body is provided with a circular tight-riveted edge, the tight-riveted edge is integrated with the nut body, and the diameter and thickness of the tight-riveted edge is set according to the diameter and thickness of a connection fastener connected with the tight-riveted edge. When the self-locking nut is screwed up, simultaneously the tight-riveted edge is tightly riveted with the connection fastener, thereby enabling the self-locking nut to have double insurance effects, and enhancing reliability, safety and stability of transmission movements of fastened pieces.
Description
Technical field
This model utility belongs to the threaded fastener that relates to mechanical field, particularly a kind of band self-locking nut on limit of riveting tightly.
Background technique
Existing self-locking nut is made up of nut body 1 and tapering locking limit 2 as shown in Figures 1 and 2, and tapering locking limit 2 is conical structure, the screw thread ovalize in tapering locking 2 holes, limit, and the screw thread in nut body 1 hole is a standard thread.In the fastening process of nut, rely on the oval screw thread distortion in tapering locking 2 holes, limit to realize self-locking.In the actual using process, there is loosening phenomenon in existing self-locking nut under the effect of dynamic load or alternate load, have influence on the Security and the reliability of transmission.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and the self-locking nut that provides a kind of band to rivet tightly the limit.
The technical solution of the utility model is: a kind of band self-locking nut on limit of riveting tightly, and it comprises nut body and tapering locking limit, the screw thread ovalize in tapering locking is lateral opening, the screw thread in the nut body hole is a standard thread.Be provided with the limit of riveting tightly of a circle in the bottom of nut body, rivet tightly limit and nut body are connected as a single entity, and the diameter on the limit of riveting tightly and thickness are according to the diameter and the thickness setting that are connected the fastening piece needs with it.
The utility model compared with prior art has following characteristics:
After self-locking nut is tightened, rivet tightly the limit simultaneously be connected fastening piece and rivet tightly, make self-locking nut have the double insurance effect, strengthened reliability, Security and the stability of fastener transmission campaign.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
