Abstract
The utility model discloses a dodecagon self-locking nut, belongs to fastening pieces, and aims to provide a self-locking nut which is reliable in loosing-prevention performance, convenient for a wrench to perform multi-angle clamping. The dodecagon self-locking nut comprises a nut body; the outer appearance of the nut body (1) is in a dodecagon structure, an annular slot is arranged at the outlet close to a screw hole; a clamping spring (3) is arranged in the annular slot; and a screw guide hole (2) is formed at the inlet of the screw hole. The dodecagon self-locking nut has the advantages of simple structure, convenience and quickness in use, reliability in loosing-prevention performance and the like, and is a self-locking nut which is suitable for being used in the fields of automobiles, ships, aviation and the like.
Description
Technical field
The utility model relates to a kind of fastening piece, relates in particular to a kind of self-locking nut.
Background technique:As everyone knows, self-locking nut is to be used in the machine building industry two or more component are connected a kind of fastening piece of fixing, preventing that the component generation from becoming flexible, is usually used in the bigger equipment of vibration such as aircraft, automobile, boats and ships, engineering machinery.At present, thus usually adopt to increase elastic washer, toothed washer or increase the frictional force that mode such as flange adds big nut at the end face of nut and improve its self-locking performance; Yet in the high vibration environment, nut still can become flexible, self-locking property is still unreliable.In addition, present nut is hexgonal structure mostly, and in the restriction of some special occasions because of the mounting point, spanner just can't carry out effective clamping, tighten later on turning over several angle nut again, uses very inconvenient.
Summary of the invention:In order to overcome the defective that exists in the existing technology, the utility model aims to provide the dodecagon self-locking nut that a kind of anti-loosening property is reliable, be convenient to the clamping of spanner multi-angle.
To achieve these goals, the utility model adopts following technological scheme: comprise nut body; The profile of nut body is the dodecagon structure, is provided with annular groove in the outlet near screw, is provided with jump ring in this annular groove, is provided with the screw thread bullport in the ingress of said screw.
Compare with existing technology, the utility model has increased jump ring owing to adopted technique scheme in the screw of plain nut, and therefore this jump ring can embed externally threaded big footpath and cooperate with bolt formation when nut cooperates with bolt; Effectively avoided nut to come off, improved fastening ability greatly because of vibration.In addition, because common six-sided nut has been changed into the dodecagon structure, therefore increased the angle of spanner clamping nut, even if also can the convenient wrench clamping under the narrower and small situation of installing space, very convenient fast.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure: nut body 1 screw thread bullport 2 jump rings 3
Embodiment:Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
As shown in Figure 1: the profile of nut body 1 is the dodecagon structure, is provided with annular groove in the outlet port near screw, is provided with two jump rings 3 in this annular groove, is provided with in the ingress of said screw to be convenient to the screw thread bullport 2 that screw rod is screwed into.
