Abstract
The utility model discloses a dodecagonal locking nut, belongs to a fastening piece and aims at providing a locking nut with reliable self-locking performance and convenience for multi-angle clamping of a wrench. The dodecagonal locking nut comprises a nut body, wherein the shape of the nut body (1) is a dodecagonal structure; a ring groove is arranged at an outlet close to a screw hole; a nylon ring (3) is fixed in the ring groove; and a thread guide hole (2) is arranged at an inlet of the screw hole. The dodecagonal locking nut disclosed by the utility model has the advantages of simple structure, convenient and fast use and reliable self-locking performance and the like, and is suitable for being used in the fields such as automobiles, ships and aviation and the like.
Description
Technical field
The utility model relates to a kind of fastening piece, relates in particular to a kind of lock nut.
Background technique:As everyone knows, lock 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 lock nut that a kind of self-locking 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 port near screw, is fixed with nylon 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 nylon ring owing to adopted technique scheme in the screw of plain nut, and therefore this nylon ring can embed externally threaded path 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 nylon 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 fixed with nylon ring 3 in this annular groove, is provided with in the ingress of said screw to be convenient to the screw thread bullport 2 that bolt is screwed into.
