Abstract
The utility model discloses a kind of locknut, including nut, the nut is composed of nut overcoat and interior elastic swivel nut, and nut overcoat upper surface is equipped with upper notch, and nut overcoat lower end surface is equipped with lower notch；The interior elastic swivel nut is equipped with bending corresponding with upper notch and lower notch position, and the tangent line of the bending and interior elastic swivel nut is at 90 degree of angles；The interior elastic swivel nut is installed at upper notch by the bending in one end precession nut overcoat, rotated to interior elastic swivel nut upper end.The utility model structure is simple, easy to use and operation, there is certain gap between spiral shell diameter in interior elasticity swivel nut outer diameter and nut overcoat when being coupled, because interior elastic swivel nut internal diameter is less than bolt outer screw diameter, when screw bolt and nut connects, the elastic force of interior elasticity swivel nut is tightly placed in interior elastic swivel nut on bolt or screw rod, to strengthen the frictional force of bolt or screw rod and interior elastic swivel nut and achieve the purpose that locking.
Description
Technical field
The utility model belongs to standard component nut more particularly to a kind of locknut.
Background technique
Make a general survey of the connection of current mechanical bolt to equipment can longtime running play conclusive effect, the company of bolts and nuts
Connect the vibration that generates in equipment operation and be easy to make its loosening, bolts and nuts connection it is locking be unremitting research class
Topic.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts, providing one kind can be such that bolts and nuts connect
Connect the steady locknut structure of longtime running.
In order to achieve the above object, the technical solution of the utility model is achieved in that
A kind of locknut, including nut, the nut are composed of nut overcoat and interior elastic swivel nut, nut
Housing upper surface is equipped with upper notch, and nut overcoat lower end surface is equipped with lower notch；The interior elastic swivel nut be equipped with upper notch and
The tangent line of the corresponding bending of lower notch position, the bending and interior elastic swivel nut is at 90 degree of angles；The interior elastic swivel nut by
In one end precession nut overcoat, the bending rotated to interior elastic swivel nut upper end is installed at upper notch and prevents from falling off.
Upper notch and the lower axially symmetric setting of notch on the nut overcoat.
The interior elastic swivel nut is identical with nut overcoat flute profile, when cooperation interior elastic swivel nut outer diameter with nut overcoat internal diameter it
Between be equipped with certain gap.
The interior elastic swivel nut internal diameter is less than bolt or outer screw diameter with its mating installation.
The utility model has the advantages that: the utility model structure is simple, easy to use and operation, interior elasticity when being coupled
There is certain gap in swivel nut outer diameter and nut overcoat between spiral shell diameter, because interior elastic swivel nut internal diameter is less than bolt or outer screw diameter,
When screw bolt and nut connects, the elastic force of interior elasticity swivel nut is tightly placed in interior elastic swivel nut on bolt screw rod, when nut loosening,
Notch on nut overcoat drives crooked position on interior elastic swivel nut, so that interior elastic swivel nut internal diameter is become smaller, to strengthen bolt
The frictional force of screw rod and interior elastic swivel nut and achieve the purpose that locking.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is nut overcoat structural schematic diagram.
Fig. 3 is interior elastic screw bushing structure schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
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.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
Locknut as shown in the figure, including nut, the nut are combined by nut overcoat 2 and interior elastic swivel nut 1
It forms, 1 upper surface of nut overcoat is equipped with upper notch 2-1, and 1 lower end surface of nut overcoat is equipped with lower notch 2-2, the nut overcoat 1
On upper notch 2-1 and the axially symmetric setting of lower notch 2-2.The interior elastic swivel nut 1 is equipped with and upper notch 2-1 and lower slot
The tangent line of the corresponding bending 1-1 in the position mouth 2-2, the bending 1-1 and interior elastic swivel nut 1 is at 90 degree of angles；The interior elasticity
Swivel nut 1 is installed at upper notch 2-1 by the bending 1-1 in one end precession nut overcoat 2, rotated to 1 upper end of interior elastic swivel nut
It prevents from falling off.
The interior elastic swivel nut 1 is identical with 2 flute profile of nut overcoat, when cooperation interior elastic 1 outer diameter of swivel nut in nut overcoat 2
Diameter is equipped with certain gap.Interior elastic 1 internal diameter of swivel nut is less than bolt or outer screw diameter with its mating installation.
In use, interior elasticity swivel nut 1 can be screwed in from about 2 any one direction of nut overcoat, when interior elastic swivel nut 1 is whole
It is screwed into nut overcoat 2, and when the upper bending 1-1 of interior elastic 1 upper end of swivel nut is installed on notch 2-1, it is therefore an objective to
Elastic swivel nut 1 falls off in order to prevent.Due to the internal diameter of the interior elastic swivel nut 1 of the utility model be slightly less than need it is to be mounted
Bolt or outer screw diameter, interior elasticity 1 outer diameter of swivel nut be also slightly less than with 2 internal diameter of nut overcoat, also be provided between the two certain
Gap therefore screw in bolt or can be big by interior elastic 1 size of swivel nut support when screw rod, the elastic force of interior elasticity swivel nut 1 makes interior elasticity
Swivel nut is tightly placed on bolt or screw rod, this also make it is mutually matched even closer between interior elastic swivel nut 1 and nut overcoat 2, still
An adapter sleeve is such as installed additional outside bolt or screw rod.
When nut loosening, the upper notch 2-1 on nut overcoat 2 drives the position bending 1-1 on interior elastic swivel nut 1, makes
Interior elasticity 1 internal diameter of swivel nut becomes smaller, to strengthen the frictional force of bolt or screw rod and interior elastic swivel nut 1 and reach locking mesh
's.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
