Abstract
The utility model discloses a kind of stop nuts, belong to nut field, including protection rubber plug, unloading nut, elastic nut and main nut, the inside groove of the main nut goes out reason by heat and is put into elastic nut, unloading nut is mounted on main nut, unloading nut is connect with screw clearance fit, and shield rubber plug is mounted on main nut.The utility model is locking to realize by the elastic nut generation pretightning force in main nut, elastic nut in nut be normally in deformation i.e. without pretightning force in the state of, elastic nut deformation generates pretightning force and firmly grasps screw to realize that main nut is locking after unloading nut is unclamped, main nut can be removed by such as needing to dismantle the compression elastic nut elimination preload of Shi Xiantong unloading nut, be easy to use.
Description
Technical field
The utility model relates to a kind of nut, specifically a kind of stop nut.
Background technique
The most common threaded fastener of nut, nut are that the fastening that workpiece is realized with pretightning force is contacted using screw thread pair.Spiral shell
Mother is exactly nut, is threaded together the part for playing the role of fastening with bolt or screw rod, it is all manufacture it is mechanical must
A kind of element is divided into carbon steel, stainless steel, several big types of non-ferrous metal (such as copper) according to the difference of material.Nut is will be mechanical
The part that equipment closely connects can just be linked together by the screw thread and bolt of inside.Due between bolts and nuts
There are gap, as the high-frequency vibration of workpiece or stress pretightning force disappearance nut just will appear loose phenomenon in practical application,
It being fallen off gradually by fastener loosening, the industrial accident as caused by the loosening of screw thread occurs often, the use of nut is influenced,
It is easy to cause security risk.
Utility model content
It is led to the problem of for existing one, the purpose of this utility model is to provide a kind of stop nuts, on solving
State the problem of proposing in background technique.
To achieve the above object, the utility model provides the following technical solutions:
A kind of stop nut, including protection rubber plug, unloading nut, elastic nut and main nut, the inside groove of the main nut
Go out reason by heat and be put into elastic nut, unloading nut is mounted on main nut, and unloading nut is connect with screw clearance fit, protects glue
Plug is mounted on main nut.
As a further solution of the present invention: the unloading nut is equipped with erosion shield.
As a further solution of the present invention: the main nut outer wall is equipped with erosion shield.
As a further solution of the present invention: the unloading nut outer wall is equipped with screw thread, unloading nut passes through outer wall
Screw thread and main nut internal screw thread connect.
As a further solution of the present invention: the elastic nut is arc setting.
Compared with prior art, the utility model has the beneficial effects that the utility model is by the elasticity in main nut
It is locking to realize that nut generates pretightning force, the elastic nut in nut be normally in deformation i.e. without pretightning force in the state of, when unloading
Elastic nut deformation generates pretightning force and firmly grasps screw to realize that main nut is locking after power nut unclamps, and such as needs to dismantle Shi Xiantong
Unloading nut, which compresses elastic nut, which to be eliminated to pre-tighten, can remove main nut, be easy to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of stop nut.
Fig. 2 is the connection cross-sectional view of stop nut.
In figure: 1, protection rubber plug, 2, unloading nut, 3, elastic nut, 4, main nut, the 5, first workpiece, 6, second workpiece,
7, screw.
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 without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment one: a kind of stop nut referring to FIG. 1-2, including protection rubber plug 1, unloading nut 2,3 and of elastic nut
Main nut 4, the inside groove of main nut 4 go out reason by heat and are put into elastic nut 3, and unloading nut 2 is mounted on main nut 4, unloads power spiral shell
Mother 2 is that clearance fit is connect with screw 7, and elastic nut 3 is normally in the state of having pretightning force in deformation, and shield rubber plug 1 is installed
On main nut 4, first unloading nut 2 and main nut 4 are tightened, the elastic nut 3 in main nut 4 is flattened by unloading nut 2, by
It is driven plain in elastic nut 3 so lose deformation pretightning force, because unloading nut 2, elastic nut 3 in anti-loosen screw nut component,
Main nut 4 and screw 7 are clearance fits, can easily tighten stop nut, and the first workpiece 5, second workpiece 6 are by screw 7 and locking
Unloading nut 2 is unclamped after nut assembly is fixed, elastic nut 3 generates pretightning force and firmly grasps the realization nut anti-looseness effect of screw 7, in order to
Unloading nut 2 is taken away in protection stop nut and the release of screw 7, and protection rubber plug 1 is installed on main nut 4.
The method for dismounting of this stop nut is as follows, takes away the protection installation of rubber plug 1 and tightens unloading nut 2, elastic nut 3 is pressed
The flat pretightning force that loses unclamps main nut 4 i.e. detachably with spanner again.
Embodiment two: the unloading nut 2 and 4 outer wall of main nut are applied equipped with anticorrosion on the basis of example 1
Layer, avoids corroding, and is easy to use.
2 outer wall of unloading nut is equipped with screw thread, and unloading nut 2 is connect by the screw thread of outer wall with the internal screw thread of main nut 4, protects
The stabilization of connection is demonstrate,proved, is easy to use.
Elastic nut 3 is arc setting, guarantees the pretightning force of deformation.
It should be strongly noted that main nut, protection rubber plug, unloading nut, elastic nut are the application's in the application
Innovative point efficiently solves industrial accident caused by the loosening of the screw thread of existing nut and occurs often, influences nut
Use, the problem of be easy to causeing security risk.
In conclusion the preferable case study on implementation of only the utility model, above makees the better embodiment of this patent
It is described in detail, but this patent is not limited to the above embodiment, and the non-limiting protection scope of the utility model, in ability
The those of ordinary skill in domain within the scope of knowledge, can also make various changes under the premise of not departing from this patent objective
Change.It is intended that including all changes that fall within the meaning and scope of the equivalent elements of the claims in the utility model
It is interior.Any reference signs in the claims should not be construed as limiting the involved claims.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
