It is the part for closely connecting mechanical equipment, by the screw thread of inside, equivalent specifications nuts and bolt can just be connected to one
It rises, wind-power electricity generation refers to that the kinetic energy kept watch switchs to electric energy.Wind is a kind of energy of not public hazards, utilizes wind-power electricity generation very ring
It protects, and the electric energy that can be generated is very huge, therefore more and more countries more pay attention to wind-power electricity generation, wind power plant needs
Various strong wind are kept out, so the anti-loosening performance of wind power plant nut is particularly important, once nut loosening consequence is not
It may imagine.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of wind-power electricity generation nut, Neng Gouli
With the connection tightness between secondary locking nut and the cooperation stiffnut and equipment of locking device, it effectively prevent loosening.
To achieve the above object, the utility model proposes a kind of wind-power electricity generation nuts, including nut body, secondary locking screw
Female, several locking devices are equipped with internal screw thread in the nut body vertically, are equipped with several locks vertically on the nut body
Tight device installation through-hole is equipped with locking device in the locking device installation through-hole, and the nut body upper end is equipped with
Convex annular looping, the annular protrusion ring outer wall are equipped with convex annular looping external screw thread, and the convex annular looping is equipped with pair
Locking nut, the secondary locking nut is interior to be equipped with the secondary locking nut internal screw thread that can cooperate with convex annular looping external screw thread,
The secondary locking nut lower end and locking device cooperates.
Preferably, the locking device includes thimble, spring, the thimble and locking device installation through-hole are slided
Connection, the thimble lower end are equipped with spring, and the locking device installation through-hole lower end is equipped with the platform that can cooperate with spring
Terrace.
Preferably, the length of the thimble is slightly longer than the depth of locking device installation through-hole.
Preferably, the thimble lower end is equipped with tip.
Preferably, being at least set to two groups of locking devices on the nut body.
If a kind of wind-power electricity generation nut of the utility model the utility model has the advantages that the utility model by will in nut body be arranged
Dry locking device is extruded the thimble of locking device by locking secondary locking nut, and the tip of thimble lies directly against nut institute
The position that need to be fixed enhances frictional force, effectively prevent loosening, and improves safety.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
