The locking nut of female Hui Song.
Currently, used hexagon slotted nut is the female one of slot on bolt, after nut tightening, by from otch
Be equipped with pin hole symmetrically local insertion opening pin with bolt end, it is locking to carry out, due to this slotted nut six it is symmetrical
It is 60 ° between otch, when nut fastens to a certain extent, the notch of pin hole and slotted nut on bolt is often mutual
It cannot be aligned, to penetrating split pin or needing tightly against fastening nut, be aligned by force, nut can be made long-term with bolt in this way
It is in a state of fatigue, it is easy running fracture.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, a kind of fluting hexagonal spiral shell with self-locking function is proposed
Mother can prevent the automatic Hui Song of nut, with fixture nut, guarantee that rotating effect is good, prevent the generation of slipping phenomenon, and intensity is high,
It is not easy to loosen when vibrated, suitable for there is the occasion of vibration, impact, the logical pretightning force for strengthening protrusion and bolt, so that nut
With self-locking property, in addition the anti-loosing effect of split pin, it is not easy to loosen, can satisfy under the harsh environments such as vibration environment
Fastening requirements, locking effect can be improved.
To achieve the above object, the invention proposes a kind of hezagon castle nuts with self-locking function, including nut sheet
Body, the cross sectional shape of the nut body are regular hexagon, and the bottom of the nut body is equipped with gasket, the gasket
Cross sectional shape be circle, the top of the nut body is equipped with protrusion, is uniformly provided with several grooves, institute in the protrusion
Six sides of the groove stated and the nut body are correspondingly arranged, and are passed through at the center of the nut body, gasket and protrusion
It is equipped with threaded hole, screw thread is equipped in the threaded hole, the middle part of the screw thread is equipped with retaining ring.
Preferably, around the threaded hole, circumferentially shape arranges the protrusion with groove.
Preferably, the length of the described protrusion is greater than the length of the groove, the height of the protrusion with it is described
Groove it is identical.
Preferably, the protrusion and the quantity of groove are 6.
Preferably, the diameter of the gasket is greater than the maximum width of the nut body.
Preferably, the height of the nut body is greater than the height of described protrusion and groove, the protrusion and
The height of groove is greater than the height of gasket.
Preferably, the nut body, gasket and protrusion are an integral structure.
Beneficial effects of the present invention: the present invention is coupled by groove and split pin, prevents the automatic Hui Song of nut, with solid
Determine nut, screw thread be equipped on the inside of groove, when split pin after such insertion, guarantee that rotating effect is good, prevent the generation of slipping phenomenon, make
Obtaining this hexagon slotted nut has many advantages, such as intensity height, is not easy to loosen when vibrated, suitable for there is the occasion of vibration, impact,
By protrusion, six protrusions are in the closing-in structure that central axis is concentrated, and after by hex nut spinning on bolt, bolt can be incited somebody to action
It being strutted in the protrusion of pre- closing-in structure, protrusion has the tendency that a kind of contraction, so that the pretightning force of protrusion and bolt is strengthened, so that
Nut has self-locking property, in addition the anti-loosing effect of split pin, it is not easy to loosen, can satisfy the harsh ring such as vibration environment
Locking effect can be improved by retaining ring in fastening requirements under border.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
