Nut is easy the problem of loosening after being spirally connected.
In order to solve the above technical problems, the technical solution of the utility model is:
A kind of Anti-loose fastener including coaxially connected bolt, nut and locks bolt, bolts and nuts dextrorotation screw thread
Connection, locks bolt and is threadedly coupled with bolt and nut derotation.
Wherein, the internal thread hole of nut includes the dextrorotation threaded hole and the first derotation threaded hole of coaxial arrangement, bolt and just
Rotation thread segment match, lock bolt include coaxial arrangement the first derotation stud and the second derotation stud, the first derotation stud and
First derotation corresponding threaded holes close, and bolt end is coaxially provided with the second derotation threaded hole, the second derotation stud and the second derotation spiral shell
Pit matches.
Wherein, the hole wall between dextrorotation threaded hole and the first derotation threaded hole is equipped with the first escape.
Wherein, the post jamb between the first derotation stud and the second derotation stud is equipped with the second escape.
Wherein, the end of the first derotation stud is coaxially provided with hexagon ring.
After above-mentioned technical proposal, the beneficial effects of the utility model are:
Since Anti-loose fastener includes bolt, nut and locks bolt, bolts and nuts dextrorotation is threadedly coupled, and locks bolt
It is threadedly coupled with bolt and nut derotation, it is locked by locking bolt and being formed to the derotation path of bolt and nut, improve bolt
The fastness and anti-loosening performance coupled with nut.
In conclusion the utility model solves the skill of bolts and nuts anti-loosening ability difference after connection in the prior art
Art problem, the utility model make bolt and nut couple after have back locking function, improve fastener entirety fastness and
Anti-vibration, anti-turn-knob ability, greatly reduce the loosening probability of bolts and nuts, improve applicability, while the utility model
Also have the characteristics that easy to process, easy to use.

Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
The orientation being related in this specification be subject to the utility model Anti-loose fastener work normally when orientation,
Orientation when its storage and transport is not limited, is only represented opposite positional relationship, is not represented absolute positional relationship.
Embodiment one:
As shown in Figure 1, Anti-loose fastener includes bolt 10, nut 20 and locks bolt 30, bolt 10, nut 20 and
Lock 30 three of bolt be it is coaxially connected, bolt 10 is that dextrorotation is threadedly coupled with nut 20, for realizing the locking function of fastener
Can, it locks bolt 30 while being threadedly coupled with bolt 10 and 20 derotation of nut, realize the back locking function of fastener,
As Fig. 2 to Fig. 5 jointly shown in, the internal thread hole of nut 20 includes two sections, as coaxial dextrorotation threaded hole 201 with
The external screw thread of first derotation threaded hole 202, bolt 10 is connect with the screw-internal thread fit of dextrorotation threaded hole 201, and locking bolt 30 is two
Rank stepped ramp type threaded post, 302 two parts of the first derotation stud 301 and the second derotation stud including coaxial arrangement, the first derotation
The external screw thread of stud 301 is connect with the screw-internal thread fit of the first derotation threaded hole 202, and the hitching post end of bolt 10 is coaxially machined with
Second derotation threaded hole 101, the external screw thread of the second derotation stud 302 are connect with the screw-internal thread fit of the second derotation threaded hole 101,
Preferred nut 20 is hex nut 20 in present embodiment, and the end of the first derotation stud 301 is coaxially provided with hexagon ring 304, side
Just it is tightened with die nut.When specifically used, first with monkey wrench or fork spanner by bolt 10 with nut 20 tight
