Description
Technical field
The present invention relates to mechanical spare and accessory parts technical fields, relate in particular to a kind of locking combination nut of prefastening.
Background technology
Currently, combination nut purposes in commercial Application is very extensive.That the most famous is the Hard-Lock of Japan, number
Claim the nut of never becoming loose.The technological core of this combination nut is：Female nut is an eccentric nut, and attaching nut then rises
To the effect of fixed eccentric nut.This nut combination is in use, and the effect of useful eccentric force often leads to the screw thread of bolt
Symmetry is lost, and due to eccentric effect, there are potential dangers to bolt for installation process.Meanwhile production is this with eccentric spiral shell
The nut of line, production cost is more high, and production technology is complex.
The content of the invention
The present invention provides a kind of locking combination nuts of prefastening, it is intended to make up above-mentioned technological deficiency.
Its technical solution is as follows：
A kind of locking combination nut of prefastening, including main nut, secondary nuts and bolt.The main nut is equipped with spiral shell in main nut
Line and main nut external screw thread, the pair nut are equipped with the first internal thread and the second internal thread；The bolt includes head and bar
Body, the body of rod are equipped with bolt external screw thread；First internal thread is identical with screw pitch, the structure of main nut internal thread, and with
The externally threaded screw pitch of bolt, structure are corresponding；The main nut, secondary nut sequentially pass through main nut internal thread, the first internal thread
With bolt is externally threaded engages, be fixed as one with bolt；Second internal thread screw pitch externally threaded with main nut, structure phase
It is corresponding；The main nut is fixed as one with secondary nut by main nut external screw thread with engaging for the second internal thread；Described first
The screw pitch of internal thread and the second internal thread is different.
Preferably, in the locking combination nut of above-mentioned prefastening：The main nut internal thread and main nut external screw thread are all adopted
With 30 ° of wedge threads.
It is further preferred that in the above-mentioned locking combination nut of prefastening：The screw pitch of first internal thread is than the second internal thread
Big/small 0.01-0.1mm of screw pitch.
It may further be preferable that in the above-mentioned locking combination nut of prefastening：The screw pitch of first internal thread than second in
Big/small 0.01-0.05mm of screw pitch of screw thread.
By using this technical solution：Main nut and secondary nut are engaged by main nut external screw thread and the second internal thread
It is fixed as one.The body of rod of bolt is through main nut and secondary nut is screwed into after workpiece simultaneously, and the bolt external screw thread on the body of rod is successively
It is engaged with main nut internal thread, the first internal thread, bolt is made to be fixed as one successively with main nut, secondary nut.Because in first
The screw pitch of screw thread and the second internal thread is different, during bolt is screwed into, generates the effect of iteration locking, it is achieved thereby that with
The same combination nut locking functions of Hard-Lock.
Compared with prior art, the present invention without eccentric nut realize with the same anti-loosening properties of Hard-Lock,
And it is easy to loading and unloading, processing technology is simple, low processing cost, securely and reliably.

Specific embodiment
Below in conjunction with the embodiment 1 shown in Fig. 1-4, the present invention will be further described.
A kind of locking combination nut of prefastening, including main nut 1, secondary nut 2 and bolt 3.The main nut 1 is equipped with master
Nut inner thread 11 and main nut external screw thread 12, the pair nut 2 are equipped with the first internal thread 21 and the second internal thread 22.Bolt
3 include head 31 and the body of rod 32, and the body of rod 32 is equipped with bolt external screw thread 33.First internal thread 21 and spiral shell in main nut
Screw pitch, the structure of line 11 are identical, and corresponding with the screw pitch of bolt external screw thread 33, structure；The main nut 1, secondary nut 2 are sequentially
It is engaged with bolt external screw thread 33 by main nut internal thread 11, the first internal thread 21, is fixed as one with bolt 3.Described
Two internal threads 22 are corresponding with screw pitch, the structure of main nut external screw thread 12；The main nut 1 and secondary nut 2 by main nut outside
Screw thread 12 is fixed as one with the second engaging for internal thread 22.The main nut internal thread 11 and main nut external screw thread 12 all use
30 ° of wedge threads.And the screw pitch of first internal thread 21 uses standard pitch.And the screw pitch of the second internal thread 22 is than standard spiral shell
Away from big 0.01-0.05mm.
In practice：Main nut 1 is fixed with secondary nut 2 by main nut external screw thread 11 with the second engaging for internal thread 22 first
It is integrated.The body of rod 32 of bolt 3 is through being screwed into main nut 1 and secondary nut 2 after workpiece 4 simultaneously, the bolt external screw thread on the body of rod 32
33 engage successively with main nut internal thread 11, the first internal thread 21, and bolt 3 is made to be fixed as one with main nut 1, secondary nut 2 successively
Body.Because the first internal thread 21 is different with the screw pitch of the second internal thread 22, during bolt 3 is screwed into, iteration locking is generated
Effect, it is achieved thereby that with the same combination nut locking functions of Hard-Lock.
The above is only the embodiment of the present invention, and the present invention is not only restricted to the limitation of above-described embodiment, all according to this hair
Similar modification, variation and the replacement that bright technical spirit makees above-described embodiment still fall within the scope of technical solution of the present invention
It is interior.Protection scope of the present invention is only defined by tbe claims.
