Description
Technical field
The present invention relates to a kind of screw retention locking method and never becoming loose bolts, belong to technical field of fastening.
Background technology
Bolt is a kind of common fastener, is widely used in various mechanically and electrically equipment.For common application occasion,
There is no particularly severe requirement to the locking characteristic of bolt.But come for fields such as automobile, Aeronautics and Astronautics and nuclear power plants
It says, many equipment or component are chronically under vibration environment and work, and generation is easy between bolts and nuts and is loosened, so that setting
Standby normal work is affected or even can cause security incident.
In order to solve the problems, such as screw retention, occur various self-locking nuts in existing Investment in fastener industry,
Complicated, production cost is high, and installs inconvenience, and anti-loosing effect is undesirable.In addition, the work of existing self-locking nut is former
Reason is all using external force the screw thread of nut or screw pitch to be made to generate distortion variation, to obtain additional pretightning force, reaches anti-and uncages
Tight purpose.However, this mode not only make screw be screwed into torque increase, but also be twisted destruction screw thread or screw pitch without
Method is recovered, and causes the nut after use or screw that cannot reuse, waste of resource.
The content of the invention
In order to solve the above-mentioned technical problem, a kind of screw retention locking method of offer of the invention and never becoming loose bolt,
It can not only achieve the purpose that anti-loosening locking, and any damage, screw and spiral shell not caused to the screw and nut after using
Mother still can be continuing with, cost-effective.
What the present invention was formed by：It is right to process a section first on the screw rod of bolt for a kind of screw retention locking method
The left-handed thread section that rotation thread segment and a section are connected with right-handed thread section, and the diameter of right-handed thread section is made to be more than left hand thread
One right-handed thread nut and a left-hand nut, are then movably connected by the diameter of section, and formation one can be with
The disjunctor nut that relatively rotates but can not separate, screws in disjunctor nut on the screw rod of bolt at this time, suitable when screwing in disjunctor nut
Clockwise rotates right-handed thread nut, and the right-handed thread nut on disjunctor nut is made to connect with the right-handed thread section screw thread on screw rod
It connects, while counterclockwise rotation left-hand nut, make the left-handed spiral shell on the left-hand nut and screw rod on disjunctor nut
Line section is threadedly coupled, until right-handed thread nut and left-hand nut are located at the right-handed thread section and left hand thread of screw rod respectively
Section intersection both sides, at this time right-handed thread nut due to be subject to left-hand nut restraining function and barrier effect and can not
Continue to rotate, similary left-hand nut can not also continue to revolve due to the restraining function and barrier effect that are subject to right-handed thread nut
Turn, can so make intersection self-locking of the disjunctor nut in the right-handed thread section and left-handed thread section of screw rod, reach anti-loosening locking
Purpose.
In the above method, the right-handed thread nut is flexibly connected with the contact face of left-hand nut and can be opposite
Rotation.
Meanwhile it the present invention also provides a kind of never becoming loose bolt, is connected as one including bolt head and with bolt head
Screw rod, the screw rod are made of the left-handed thread section that a section right-handed thread section and a section are connected with right-handed thread section, and right
The diameter for revolving thread segment is more than the diameter of left-handed thread section, right-handed thread nut is threaded in right-handed thread section, on a left side
Left-hand nut is threaded on rotation thread segment, the right-handed thread nut is movably connected in one with left-hand nut
It rises, forms a disjunctor nut that can be relatively rotated but can not separate.
Further, annular cone tank is offered on the end face of the right-handed thread nut, in the end face of left-hand nut
On be provided with the taper sheath being connected as one with left-hand nut, taper sheath is fitted in annular cone tank and can not exit,
So that right-handed thread nut is movably connected with left-hand nut, forming one can relatively rotate but can not separate
Disjunctor nut.
Further, the oral area outer rim of the taper sheath is provided with rounded corners.
Further, the right-handed thread nut and the threaded hole on left-hand nut are concentric.
Further, the right-handed thread nut is identical with the screw pitch of left-hand nut so that right-handed thread nut and
Left-hand nut can synchronous rotary, ensure that right-handed thread nut and left-hand nut can be synchronously threaded in or out.
By adopting the above-described technical solution, the advantage of the invention is that：The present invention uses the mutual containing of disjunctor nut
It acts on mutual barrier effect achieving the purpose that anti-loosening locking, it is not only easy to assembly, but also to the screw and nut after using
Any damage is not caused, screw and nut still can be continuing with, cost-effective.Therefore, anti-loosening locking effect of the present invention
Good and simple in structure, manufacture is at low cost, convenient for mass production.

Specific embodiment
In order to make the object, technical solutions and advantages of the present invention clearer, with reference to the accompanying drawings and examples to this hair
It is bright to be described in further detail.
The embodiment of the present invention：As shown in Figures 1 and 2, never becoming loose bolt of the invention, including bolt head 1 and with
The screw rod 2 that bolt head 1 is connected as one, the screw rod 2 are connected by a section section of right-handed thread section 5 and one with right-handed thread section 5
The left-handed thread section 6 connect forms, and the diameter of right-handed thread section 5 is more than the diameter of left-handed thread section 6, in right-handed thread section 5
Right-handed thread nut 3 is threaded with, left-hand nut 4, the right-handed thread spiral shell are threaded in left-handed thread section 6
Annular cone tank 7 is offered on the end face of mother 3, is provided on the end face of left-hand nut 4 and is connected with left-hand nut 4
The taper sheath 8 being integrated, taper sheath 8 are fitted in annular cone tank 7 and can not exit, so that right-handed thread nut 3 and a left side
Rotation screw nut 4 is movably connected, and forms a disjunctor nut that can be relatively rotated but can not separate, and right-handed thread
Nut 3 and the threaded hole on left-hand nut 4 are concentric.The oral area outer rim of the taper sheath 8 is provided with rounded corners 9, is convenient for
Taper sheath 8 is pressed into annular cone tank 7, improves efficiency of assembling.The spiral shell of the right-handed thread nut 3 and left-hand nut 4
Away from identical so that right-handed thread nut 3 and left-hand nut 4 can synchronous rotary, ensure right-handed thread nut 3 and left-handed
Screw nut 4 can be synchronously threaded in or out.
The operation principle of the present invention：The screw rod 2 of bolt is penetrated into connected piece first, disjunctor nut is then screwed in into bolt
Screw rod 2 on, screw in disjunctor nut when, be rotated clockwise right-handed thread nut 3, make the right-handed thread spiral shell on disjunctor nut
Mother 3 is threadedly coupled with the right-handed thread section 5 on screw rod 2, while counterclockwise rotation left-hand nut 4, makes disjunctor nut
On left-hand nut 4 be threadedly coupled with the left-handed thread section 6 on screw rod 2, until right-handed thread nut 3 and left hand thread spiral shell
Mother 4 respectively positioned at screw rod 2 right-handed thread section 5 and 6 intersection of left-handed thread section both sides, at this time right-handed thread nut 3 due to
Be subject to left-hand nut 4 restraining function and barrier effect and can not continue to rotate, similary left-hand nut 4 is due to being subject to
The restraining function and barrier effect of right-handed thread nut 3 can not also continue to rotate, and can so make disjunctor nut on the right side of screw rod 2
Thread segment 5 and the intersection self-locking of left-handed thread section 6 are revolved, achievees the purpose that anti-loosening locking.
