Abstract
The utility model discloses a kind of tensile high-locking nut, including nut body, the nut body includes sequentially connected turret head, cylinder and frustum column, the turret head, cylinder and frustum column are integrally formed, concentric first through hole, the second through hole and third through-hole are respectively equipped with the turret head, cylinder and frustum column, the inner surface of second through hole is equipped with screw thread.The utility model can reduce infringement of the pulling force to connection screw thread by the deformation of hollow cone important actor, enhance the tensile property of nut using hollow frustum column is added in one end that nut connects with connector；The structure to be staggered at the same time using turret head with screw position, can avoid nut in rundown process, the frictional force of the active force increase threaded connection of spanner so that the installation of nut and fixation are more smooth and laborsaving.
Description
Technical field
It the utility model is related to threaded connector technical field, more particularly to a kind of tensile high-locking nut.
Background technology
Nut is a kind of part that can closely connect mechanical equipment, it is usually used cooperatively with bolt to reach
The purpose of parts is fastened, i.e., by the way that bolt is penetrated the through hole that connected parts are equipped with, is connected in the other end of bolt
Nut fastens parts.Due to above-mentioned connected parts in connection, it is necessary to certain pretightning force, connecting portion
Larger vibrations can be also produced during the work time, so that the opposite pulling force of certain orientation can be caused to screw bolt and nut, can be right
The reliability of threaded connection impacts, or even abrasion screw thread, causes Joint failure；Meanwhile traditional nut makes in installation, pulls
The application point of hand is located at the outside of the junction of screw thread, and the active force of spanner can increase the frictional force of threaded connection, be unfavorable for spiral shell
Female tightens fixation.
Utility model content
The purpose of this utility model is and the high lock of a kind of tensile type proposed in order to solve shortcoming existing in the prior art
Nut.
To achieve these goals, the utility model employs following technical solution：
A kind of tensile high-locking nut, including nut body, the nut body include sequentially connected turret head, cylinder
With frustum column, the turret head, cylinder and frustum column are integrally formed, and are respectively equipped with the turret head, cylinder and frustum column
Concentric first through hole, the second through hole and third through-hole, the inner surface of second through hole are equipped with screw thread.
Preferably, the nut body is made of A286 materials.
Preferably, the outer surface of turret head and the cylinder junction is equipped with annular groove.
Preferably, the diameter of the cylinder and the circumscribed circle diameter of turret head are equal.
Preferably, the first through hole is identical with the diameter of third through-hole, and is all higher than the diameter of the second through hole.
Preferably, the junction of second through hole and first through hole is equipped with chamfering, second through hole and third through-hole
Junction be equipped with chamfering.
, can be by hollow using hollow frustum column is added in one end that nut connects with connector in the utility model
The deformation of frustum column reduces infringement of the pulling force to connection screw thread, enhances the tensile property of nut；Use turret head and spiral shell at the same time
The structure that line position is staggered, can avoid nut in rundown process, the frictional force of the active force increase threaded connection of spanner so that
The installation of nut and fixation are more smooth and laborsaving.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：1 annular groove, 2 turret heads, 3 cylinders, 4 frustum columns, 5 first through hole, 6 second through holes, 7 third through-holes.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
With reference to Fig. 1, a kind of tensile high-locking nut, including nut body, nut body are made of A286 materials, nut
Body includes sequentially connected turret head 2, cylinder 3 and frustum column 4, and turret head 2, cylinder 3 and frustum column 4 are integrally formed, and six
The outer surface of 3 junction of angle head 2 and cylinder is equipped with annular groove 1, and the diameter of cylinder 3 is equal with the circumscribed circle diameter of turret head 2,
Concentric first through hole 5, the second through hole 6 and third through-hole 7, the second through hole are respectively equipped with turret head 2, cylinder 3 and frustum column 4
5 inner surface is equipped with screw thread, and first through hole 5 is identical with the diameter of third through-hole 7, and is all higher than the diameter of the second through hole 6.
Second through hole 6 and the junction of first through hole 5 are equipped with chamfering, and the junction of the second through hole 6 and third through-hole 7 is equipped with
Chamfering.
Operation principle：When the utility model is used, nut body and bolt are used cooperatively, by installation tool, such as
Spanner, applies rotating torque to turret head 2, makes nut body by screw thread with being bolted, and make end face and the company of frustum column 4
The surface of fitting is close to, and turret head 2 is staggeredly arranged with connection screw thread, the active force of spanner, will not be to the frictional force of connection screw thread
Have an impact, when producing vibrations pulling force on connector, frustum column 4 deforms upon, damping vibration pulling force, weakens pulling force to nut
Connection screw thread the extent of damage, enhance the tensile property of nut.
The above, is only the preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
