Description
Technical field：
The utility model belongs to industrial standard part technical field of fastener manufacture, is related to a kind of magnetic material in tightening technology
A kind of application in field, and in particular to locking magnetic double nut of antivibration.
Background technology：
Threaded fastener is one of most widely used accessory, and it is each to be related to industry, agricultural, traffic, national defence, daily life etc.
Individual field.The overwhelming majority is threaded in assembled and must tightened, and makes to be connected to and bears to connect before service load, is previously subjected to
The effect of power, and condition of self-locking can be met.In addition, the frictional force on the supporting surface such as nuts and bolt head after tightening also have it is anti-
Pine effect, but in the presence of shock and vibration or varying load, the frictional force between screw pair may reduce or pop-off.It is this
After phenomenon is repeated several times, connection will be released.In the case where high temperature or temperature change are larger, due to threaded connector and by
Creep and stress relaxation occur for the material of connector, and the pretightning force in connection and frictional force can also reduced, ultimately results in link
Failure.
With the fast development of science and technology, requirement of the people to threaded connection also more and more higher, especially locking, anti-
Shake etc., therefore, people have made unremitting effort, many Novel bolt, nuts with some functions are have studied, and obtain
Gratifying achievement, many innovation and creation about this respect have been disclosed in Chinese patent, wherein the overwhelming majority is all from machinery
New idea, new technology, new method, but there is not yet the application of magnetic material in this respect are proposed in terms of construction.
The content of the invention：
The purpose of this utility model is to overcome the shortcomings of prior art, there is provided a kind of locking magnetic double nut of antivibration.This
Inventing the locking magnetic double nut of a kind of antivibration provided includes a pair first magnetic nuts and the second magnetic setting up and down
Nut；First magnetic nut includes the first groove nut 1 and the first permanent magnet 4, and first groove nut 1 is general
One end of nut or non-universal nut is provided with groove 7, and first permanent magnet 4 is arranged in the groove 7, first permanent magnetism
Body 4 matches with the groove 7；The axial dimension of the groove 7 is less than the axial dimension of the groove nut 1, the groove 7
Radial dimension be less than first groove nut 1 radial dimension；The composition structure of second magnetic nut and described the
The composition structure of one magnetic nut is identical, polarity and second magnetic of the first permanent magnet 4 in first magnetic nut
The opposite polarity of the second permanent magnet 5 in nut.
The groove 7 is shaped as annular or other shapes；First permanent magnet 4 has to match with the groove 7
Geometry, first permanent magnet 4, which has, in other words can fill the geometry of the groove 7；First permanent magnetism
The inside and outside wall of body 4 is smooth surface, easy to process.
The material of first groove nut 1 and the second groove nut 2 is permeability magnetic material or non-magnet material.
First permanent magnet 4 and the second permanent magnet 5 include any of neodymium iron boron, ferrite and Nanocomposite magnet permanent magnetism
Body material or wantonly more than two kinds of composite permanent magnet material.
The antivibration that the utility model is related to, the operation principle of locking magnetic double nut：One of described magnetic nut is twisted
Tightly on bolt, make the permanent magnet N (S) in its groove extremely upward, S (N) extremely downwards, ensures that connection is pre- next, now will be separately
Extremely downwards, S (N) is extremely tightened against on bolt one magnetic nut N (S) upwards, with the reduction of the spacing of two magnetic nuts, between
Magnetic repulsion increase.After two magnetic nuts are tightened to top, up/down nut by the magnetic repulsion to up/down, makes lower nut respectively
Screw and acted on all the time by additional pressure and frictional force between screw thread, when service load has variation, the frictional force exists all the time.If
Supporting surface material is magnetic conductor, and lower nut then also by downward magnetic attraction, ensure that the presence of connection pretightning force so that upper magnetic
Property nut, magnetic nut, bolt, working interface are connected by magnetic force, so as to greatly increase their fastening
Intensity, also cause the antidetonation, locking magnetic double nut that there is good anti-loosening property and any positioning function.Due to magnetic material
Material has absorption to seismic wave so that the present invention is again with vibration damping, the function of antivibration.
If being magnetic conductor by fastener, or it is to lead in the magnetic field range when being contacted with the magnetic nut in permanent magnet
Magnet, for magnetic nut when fastening is by fastener, permanent magnet simultaneously can also be to producing magnetic attraction, so that of the invention by fastener
Antivibration, antivibration, the anti-loosening property of locking double nut further strengthened.
The locking magnetic double nut of antivibration provided by the utility model significantly improves antivibration, anti-loosening property, and has and appoint
The function of meaning positioning.When reaching same fastening strength, magnetic double nut of the present invention reduces material than common double nut
Material more than 30%.The utility model has antivibration, locking, security is good, can arbitrarily position, be simple in construction, easy to manufacture, makes
With it is convenient, retreat it is flexible, can Reusability, versatile and the features such as save material, while also open magnetic material application
Frontier.

Embodiment：
The locking magnetic double nut of a kind of antivibration provided by the utility model, as shown in Figure 1, Figure 2, Figure 3, Figure 4, the first magnetic
Property nut 1 includes the permanent magnet 4 of groove nut 1 and first.First groove nut 1 is to be provided with annular groove in one end of general nut
7, the first permanent magnet 4 matches with groove 7 and in groove 7.
As shown in Figure 1 and Figure 2, the first permanent magnet 4 is arranged in the first groove nut 1, it is noted that forever when magnetic nut is installed
The N poles of magnet are arranged close to the side of groove nut groove.By the first permanent magnet 4 in mounted first groove nut 1
N extremely screw upwards with bolt 3 tighten after be positioned at by fastener 6, by the N of the second permanent magnet 5 in the second magnetic nut 2
Extremely screw downwards and tighten with bolt.Magnetic repulsion now will be produced between the first permanent magnet 4 and the second permanent magnet 5, with two magnetic
The reduction of the spacing of nut, magnetic repulsion increase.After two magnetic nuts are tightened to top, up/down nut is respectively by the magnetic to up/down
Repulsion, lower nut is set to be acted on all the time by additional pressure and frictional force between screwing screw thread, when service load has variation, this rubs
Power is wiped all the time to exist.If it is to lead in the magnetic field range for magnetic conductor or when magnetic nut contacts in permanent magnet by fastener material
Magnet, lower nut then also by downward magnetic attraction, ensure that the presence of connection pretightning force so that upper magnetic nut, magnetic
Nut, bolt, it is connected by magnetic force by fastener, so as to greatly increase their fastening strength and locking property
Energy.
The material of groove nut can be with unlimited, you can be that permeability magnetic material can also be non-magnet material.When the groove
When nut is magnetic conductor, the permanent magnet should in advance magnetize and be reloaded into the groove, because magnetic force can be by them securely
It is connected as one；If on the contrary, when the groove nut is non-magnetizer, the permanent magnet just has to by being bonded, engaging,
The modes such as injection and the groove nut are affixed.The permanent magnet includes appointing in neodymium iron boron, ferrite and Nanocomposite magnet
A kind of permanent magnet material or wantonly more than two kinds of composite permanent magnet material.
