Description
Technical field
The utility model is related to a kind of 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 the fields such as automobile, Aeronautics and Astronautics and nuclear power plant are come
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 as to make to set
Standby normal work is affected or even can cause safety accident.
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 the screw thread of nut or screw pitch to be made to generate distortion variation using external force, 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 restored, and causes the nut after use or screw that cannot reuse, waste of resource.
Utility model content
In order to solve the above-mentioned technical problem, a kind of never becoming loose bolt of the offer of the utility model, can not only reach anti-
It uncages tight purpose, and any damage is not caused to the screw and nut after using, screw and nut still can continue
It uses, it is cost-effective.
What the utility model was formed by：A kind of never becoming loose bolt is connected as including bolt head and with bolt head
The screw rod of one, the left-handed thread section group that the screw rod is connect by a section right-handed thread section and a section with right-handed thread section
Into, and the diameter of right-handed thread section is more than the diameter of left-handed thread section, and right-handed thread spiral shell is threaded in right-handed thread section
Mother is threaded with left-hand nut, the right-handed thread nut and left-hand nut activity in left-handed thread section
It links together, 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 as to which right-handed thread nut and left-hand nut be made to be movably connected, 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 as to make right-handed thread nut and
Left-hand nut can synchronous rotary, ensure right-handed thread nut and left-hand nut can synchronize be threaded in or out.
By adopting the above-described technical solution, the utility model has the advantage of：The utility model is using disjunctor nut
Mutual restraining function and mutual barrier effect achieve the purpose that anti-loosening locking, not only easy to assembly, but also to the spiral shell after using
Nail and nut do not cause any damage, and screw and nut still can be continuing with, cost-effective.Therefore, the utility model
Anti-loosening locking effect is good, and simple in structure, and manufacture is at low cost, convenient for mass production.

Specific embodiment
It is right with reference to the accompanying drawings and examples in order to make the purpose of this utility model, technical solution and advantage clearer
The utility model is described in further detail.
The embodiment of the utility model：As shown in Figures 1 and 2, the never becoming loose bolt of the utility model, including bolt head
1 and the screw rod 2 that is connected as one with bolt head 1, the screw rod 2 is by section right-handed thread section 5 and one section and dextrorotation spiral shell
The left-handed thread section 6 that line section 5 connects forms, and the diameter of right-handed thread section 5 is more than the diameter of left-handed thread section 6, in dextrorotation spiral shell
Right-handed thread nut 3 is threaded in line section 5, left-hand nut 4, the right side are threaded in left-handed thread section 6
It revolves and offers annular cone tank 7 on the end face of screw nut 3, be provided on the end face of left-hand nut 4 and left hand thread
The taper sheath 8 that nut 4 is connected as one, taper sheath 8 is fitted in annular cone tank 7 and can not exit, so as to make right-handed thread
Nut 3 is movably connected with left-hand nut 4, 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 circle
Chamfering 9 convenient for taper sheath 8 is pressed into annular cone tank 7, improves efficiency of assembling.The right-handed thread nut 3 and left hand thread
The screw pitch of nut 4 is identical, so as to enable 4 synchronous rotary of right-handed thread nut 3 and left-hand nut, ensures right-handed thread spiral shell
Mother 3 with left-hand nut 4 can synchronize be threaded in or out.
The operation principle of the utility model：The screw rod of bolt 2 is penetrated into connected piece first, then screws in disjunctor nut
On the screw rod 2 of bolt, when screwing in disjunctor nut, right-handed thread nut 3 is rotated clockwise, makes the dextrorotation spiral shell on disjunctor nut
Line nut 3 is threadedly coupled with the right-handed thread section 5 on screw rod 2, while counterclockwise rotation left-hand nut 4, makes disjunctor
Left-hand nut 4 on nut is threadedly coupled with the left-handed thread section 6 on screw rod 2, until right-handed thread nut 3 and left-handed spiral shell
Line nut 4 is located at both sides of the right-handed thread section 5 with 6 intersection of left-handed thread section of screw rod 2 respectively, at this time right-handed thread nut 3
Can not continue to rotate due to restraining function and barrier effect by left-hand nut 4, similary left-hand nut 4 due to
It can not also be continued to rotate by the restraining function and barrier effect of right-handed thread nut 3, disjunctor nut can be made in this way in screw rod 2
Right-handed thread section 5 and left-handed thread section 6 intersection self-locking, achieve the purpose that anti-loosening locking.
