Description
Technical field
The present invention relates to a kind of nut more particularly to a kind of Anti-loosening nut, it is primarily adapted for use in and improves the anti-loosening of nut
Performance.
Background technology
The operation principle of nut is to carry out self-locking using the frictional force between nuts and bolt.But in dynamic loading this
The reliability of kind self-locking will reduce.In some important occasions, we will take some locking measures, ensure nut check
Reliability.It is exactly wherein one such locking measures with Anti-loosening nut.Fastener is being widely used, many fasteners
It is the working environment in heavy duty, vibration, it is easy to the fastener of the case where loosening, certain positions once loosens,
It is likely to cause major accident even threat to life.Therefore, improving the anti-loosening performance of nut becomes urgent problem.
Chinese patent application publication No. is CN104110433A, and data of publication of application is the patent of invention on October 22nd, 2014
Disclose a kind of auto lock Anti-loosening nut, include the nut body equipped with threaded hole, described nut body one end be equipped with to
The annular convex platform of outer extension is fixed with the flexible locking piece of annular, the elasticity of the annular in the looping pit of the annular convex platform
The centre bore of lock sheet and threaded hole are concentric, and the internal diameter of the flexible locking piece is less than the internal diameter of threaded hole, the lock sheet
Inner surface is equipped with the protrusion to hole heart radially protruding, is additionally provided with flange portion on nut body, is set on the end face of the flange portion
There are continuous radial anti-slop serrations.Although the nut can play antidetonation, anti-loosening effect, it still has following defect：
First, for the flexible locking piece which uses for metal material, the rigidity of metal locking piece is larger, shock-proof check move performance compared with
Difference.
Invention content
The purpose of the present invention is overcome shock-proof check existing in the prior art to move poor performance, complicated defect and ask
Topic provides a kind of Anti-loosening nut that the dynamic performance of shock-proof check is good, simple in structure, easy to process.A kind of Anti-loosening nut is by spiral shell
Maternal body, internal tooth washer, C-shaped ring composition, it is characterised in that C-shaped ring is the annulus that cross section is " C " shape, the C-shaped in C-shaped ring
Open recess is directed toward the center of C-shaped ring, and the plane that screw hole is arranged with nut body for C-shaped ring is affixed, the screw hole and C-shaped of nut body
Ring is concentric circles；Internal tooth washer is made of faced washer and internal tooth, and internal tooth is set on the inside round edge of faced washer through-hole, interior
Side of the teeth directional far from nut body tilts, and internal tooth is a certain included angle when tilting with washer plane, and internal tooth washer is set to C-shaped
Among ring；The plane that screw hole can be directly arranged in internal tooth washer with nut body is affixed, while removing C-shaped ring.C-shaped ring can be replaced
It is changed to L-shaped ring.When the internal tooth of internal tooth washer tilts and the plane of faced washer is formed by angle as acute angle.A kind of anti-loosening spiral shell
Mother coordinates by the contact surface of fastenings by the rotation of itself, the internal tooth compressive deformation of internal tooth washer is stuck in bolt thread
In slot, the screw rod and nut closeness of contact, mutual extruding force of bolt are increased, to improve the friction of nut and bolt
Power plays anti-loosening effect.
Advantageous effect：The present invention can efficiently solve railway, train, automobile and Other Engineering mechanized equipment because of equipment
Constantly vibration causes the common bolt device of fixed equipment to occur to loosen and the equipment breakdown of initiation, thus is conducive to improve
The safety of vibratory equipment in use.It is locking instead of tradition such as various conventional nuts, nylon stop nut, live dispensings
Dynamic method, while the piece surface being fastenedly connected will not be damaged.

In figure：Nut body 1, C-shaped ring 2, faced washer 3, internal tooth 4, screw hole 5.
Specific implementation mode
Below in conjunction with description of the drawings, the present invention is described in further detail with specific implementation mode：A kind of anti-loosening spiral shell
Mother is made of nut body 1, internal tooth washer, C-shaped ring 2, it is characterised in that C-shaped ring is the annulus that cross section is " C " shape, C-shaped ring 2
In the open recess of C-shaped be directed toward the center of C-shaped ring, the plane of C-shaped ring 2 and nut body 1 setting screw hole 5 is affixed, nut sheet
The screw hole 5 of body 1 is concentric circles with C-shaped ring 2；Internal tooth washer is made of faced washer 3 and internal tooth 4, and internal tooth 4 is set to faced washer
On the inside round edge of 3 through-holes, internal tooth 4 is tilted to the side far from nut body 1, when internal tooth 4 tilts and the plane of faced washer
It is a certain included angle, internal tooth washer is set among C-shaped ring 2；The faced washer 3 of internal tooth washer can directly with nut body 1
The plane that screw hole 5 is arranged is affixed, while removing C-shaped ring 2.C-shaped ring 2 could alternatively be L-shaped ring.The internal tooth 4 of internal tooth washer tilts
When to be formed by angle with the plane of faced washer 3 be acute angle.The material of internal tooth washer is less than bolt joined together using hardness
Metal material, for example, the materials such as copper internal tooth washer, aluminum internal tooth washer, it is ensured that while higher contact also
The screw thread of the screw rod of bolt itself will not be caused to damage.Internal tooth washer can also use the materials such as plastics, rubber, to increase
The friction coefficient of internal tooth 4 after extruding.
The method of operation：
When using the present invention, the side that a kind of Anti-loosening nut is provided with to internal tooth washer is inserted in screw rod and is constantly screwed, Zhi Daoyi
Kind Anti-loosening nut is close to by fastenings.Continue tightening nut at this time, then the contact surface of part can constantly squeeze internal tooth washer
The internal tooth 4 of tilting so that the internal tooth 4 of internal tooth washer is intended to parallel with faced washer 3 or is in same plane.Simultaneously with interior
Tooth 4 is extruded to is continuously subject to the center of the screw hole 5 of nut body 1 with faced washer approximately the same plane, 4 top of internal tooth.At this time
The screw diameter of bolt is constant, so internal tooth 4 is contacted with screw flight, and crimp, the radial card of internal tooth 4 of internal tooth washer
Tightly on bolt or in thread groove.It is the phenomenon that passive relative to conventional nylon stop nut offer friction pressure, a kind of locking
Dynamic nut is constantly tightened with nut body 1, and the internal tooth 4 of internal tooth washer is constantly squeezed by axial compressive force and radial pressure jointly
Pressure ultimately forms the extruding force of bigger and closer is engaged.It is formd between internal tooth washer and screw rod, screw thread at this time
Prodigious contact, according to frictional force calculation formula it is found that pressure is bigger, frictional force is bigger, so the present invention is a kind of locking
The locking kinetic force of friction of dynamic nut is far longer than plain nut, even greater than nylon stop nut, can play locking well
Dynamic effect.It will finally realize the locking between bolt and nut so that any loosening will not be occurred by fastenings, ensure that equipment
Reliability and safety.A kind of Anti-loosening nut is simple in structure, easy to process, easy to use, may be implemented truly
Never becoming loose.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
