Fastener is widely used on machinery, electric appliance and building.General material is metal or plastic cement, and cylinder, surface is carved with recessed
Convex ditch is known as screw thread.The quick fixation to object can be realized using screw, convenience more faster than traditional fixed form.
But general screw does not have the effect of anti-derotation, makes unexpected, theft in this way, screw back-out deliberately is caused it
The structural breakdown of connection causes various unpredictable consequences.
Therefore, how the screw in market is improved, it is made to overcome disadvantages mentioned above that can have the advantages that again above-mentioned, be ability
A field technique personnel problem urgently to be resolved hurrily.
Invention content
The purpose of the present invention is to provide a kind of anti-derotation screw, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical solution：
A kind of anti-derotation screw, including head of screw and the body of screw, the body of screw upper center offers counterbore, the spiral shell
Rivet nut top side offers plug channels, plug channels connection counterbore；The anti-derotation of screw is equipped in the middle part of the head of screw lower end
Bar, screw counnter attack swing arm lower end have been wholely set mounting head, and the side of mounting head offers mounting hole, counnter attack is equipped in mounting hole
Revolve mechanism；The screw counnter attack swing arm and mounting head are mounted in counterbore；Head of screw upper end side offers limit hole, limit
Position hole is through head of screw and extends to body of screw top, and limiting is equipped in the limit hole and is hooked, the body of screw lower part is equipped with spiral shell
Line
As improvement：The anti-derotation mechanism includes anti-derotation plug and spring, and described anti-derotation plug one end is arranged on
Inside mounting hole, spring is arranged on anti-derotation plug.
As being further improved：The anti-derotation plug is three-stage telescopic rod.
As being further improved：The material of the spring is hot rolling spring steel.
As being further improved：The shape that the limiting hooks is L shapes.
Compared with prior art, the advantage of the invention is that：Present invention reasonable design in structure is easy to use fast
Victory, practicability is very high, and the fixation for making the body of screw and object is more firm, improves the fixed safety of object, makes the anti-derotation screw
It can be very good to meet requirement.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment the present invention is described in further detail：
Fig. 1 is schematic diagram when anti-derotation screw uses；
Fig. 2 is the structure diagram of anti-derotation screw.
In figure：Spring 1, plug channels 2, mounting head 3, limiting hook 4, head of screw 5, screw counnter attack swing arm 6, the body of screw 7, spiral shell
Line 8, anti-derotation plug 9, mounting hole 10, limit hole 11.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig.1~2, in the embodiment of the present invention, a kind of anti-derotation screw is described including head of screw 5 and the body of screw 7
7 upper center of the body of screw offers counterbore, and the 7 top side of the body of screw offers plug channels 2, and the connection of plug channels 2 is heavy
Hole；Screw counnter attack swing arm 6 is equipped in the middle part of 5 lower end of head of screw, 6 lower end of screw counnter attack swing arm has been wholely set mounting head 3, pacifies
The side of dress head 3 offers mounting hole 10, and anti-derotation mechanism is equipped in mounting hole 10；The screw counnter attack swing arm 6 and mounting head 3
In counterbore；The 5 upper end side of head of screw offers limit hole 11, and limit hole 11 is through head of screw 5 and extends to spiral shell
7 top of rivet nut, the limit hole 11 is interior to be equipped with limiting hook 4, and 7 lower part of the body of screw is equipped with screw thread 8.
The anti-derotation mechanism includes anti-derotation plug 9 and spring 1, and described anti-9 one end of derotation plug is arranged on mounting hole
Inside 10, spring 1 is arranged on anti-derotation plug 9.
The anti-derotation plug 9 is three-stage telescopic rod.
The material of the spring 1 is hot rolling spring steel.
The shape that the limiting hooks 4 is L shapes.
The present invention operation principle be：The present invention is in use, limiting is hooked in 4 limit holes 11 being inserted on head of screws 5 and worn
It crosses head of screw to go directly in the body of screw 7, limiting, which hooks 4, prevents head of screw and body of screw coaxial rotating, when ensureing screw screw-in wall not
