Description
Technical field
The utility model relates to a kind of locking device, in particular, relates to a kind of major diameter axle head left-right rotary locking device with internal thread.
Background technique
At present, when the end of major diameter axostylus axostyle needs nut to tighten, because axostylus axostyle is major diameter, so nut is not easy to tighten, and machinery also can to cause nut to produce in the vibrations in when operation loosening, the degradation in the time of can causing mechanical movement, even can lead to a disaster.
For preventing the generation of nut loosening phenomenon, have special-purpose locking nut, but this locking nut should punch simultaneously at axostylus axostyle, nut, after assembling, twine again and tie up iron wire, and can not reuse; Also there is a kind of locking nut to realize with encapsulating, can not reuses equally;
Have also that to use anti-loosening left-right rotary screw thread combination bolt and nut, this assembling bolt nut be by left-right rotary screw bolt, reciprocity law power when nut cooperates, reach anti-loosening effect.But two nuts are next anti-loosening by frictional force, because the effect of frictional force also can make set screw nut Hui Song, locking effect is not very good; And constantly reciprocity law power can make frictional force constantly change, and pretightening force just is difficult for prediction like this; When locking to major diameter axle head needs, also be not easy to tighten.Up to the present, a kind of reusable major diameter axle head left-right rotary locking device with internal thread not yet appears on the market.
The model utility content
The purpose of this utility model is can not well tighten the end of major diameter axostylus axostyle and the phenomenon that nut easily becomes flexible for existing nut, and a kind of major diameter axle head left-right rotary locking device with internal thread is provided.
Major diameter axle head left-right rotary locking device with internal thread of the present utility model, comprise major diameter axostylus axostyle, clamped body and locking device, described major diameter axle end is provided with outside thread G section and internal thread H section, described locking device by set screw nut, stretching screw, push screw open and lock bolt forms, described set screw nut is tightened on outside thread G section, lock bolt screws the section at internal thread H, set screw nut and lock bolt spacing 0.5mm-20mm, described stretching screw be connected and fixed nut and lock bolt are pushed screw attachment set screw nut and lock bolt open.
Described G section is dextrorotation, and the H section is left-handed, and to be that dextrorotation is upper left screw off set screw nut, and lock bolt is left-handed upper right screwing off.
Described G section is left-handed, and the H section is dextrorotation, and set screw nut is left-handed upper right screwing off, and to be that dextrorotation is upper left screw off lock bolt.
Described set screw nut and lock bolt spacing 5mm-10mm.
Described set screw nut is tightened on the G section, lock bolt screws the section at H, 1-3 blind hole of processing on the described set screw nut circumferencial direction, 1-3 interior threaded hole, blind hole and interior threaded hole intercross arrangement, 1-3 light through hole of processing on the described lock bolt circumferencial direction, 1-3 internal thread through hole, light through hole and internal thread through hole intercross arrangement, the light through hole that the threaded front end of stretching screw passes on the lock bolt connects with internal thread on the set screw nut, push screw rear end screw thread open and screw in the internal thread through hole on lock bolt, front end withstands in the blind hole on the set screw nut.
The beneficial effects of the utility model: (1) simple in structure, be easy to make; (2) practical, can reuse; (3) because stretching screw and push the interaction of screw open, better prevent mechanical shock and the loosening phenomenon that produces; (4) avoid mutual friction between nut, prolonged the service time of nut; (5) easy for installation.

Embodiment
Described major diameter axostylus axostyle 1 end is provided with outside thread G section and internal thread H section, described G section is dextrorotation, the H section is left-handed, set screw nut 3 screws off for dextrorotation is upper left, lock bolt 5 is left-handed upper right screwing off, described set screw nut 3 is tightened on outside thread G section, lock bolt 5 screws the section at internal thread H, 2 blind holes of processing on described set screw nut 3 circumferencial directions, 2 interior threaded holes, blind hole and interior threaded hole intercross arrangement, 2 light through holes of processing on described lock bolt 5 circumferencial directions, 2 internal thread through hole, the light through hole that light through hole and internal thread through hole intercross arrangement, stretching screw 4 threaded front ends are passed on the lock bolt 5 connects with internal thread on the set screw nut 3, pushes screw 6 rear end screw threads open and screws in the internal thread through hole on lock bolt 5, front end withstands in the blind hole on the set screw nut 3, set screw nut 3 and lock bolt 5 spacing 10mm.
Like this when mechanical movement, because vibrations, set screw nut 3 loosening meeting will occur to anticlockwise, because the front end of stretching screw 4 has screw thread, the rear end is without screw thread, at this moment stretching screw 4 can make the pretightening force of 2 of set screw nut 3 and clamped bodies diminish, and there is screw thread the rear end of pushing screw 6 open, and front end is without screw thread, guaranteed that set screw nut 3 and lock bolt 5 spacings are constant, and reach a balance with stretching screw 4, thereby it is left-handed to drive lock bolt 5, has prevented the loosening of nut.Because set screw nut 3 has certain distance with lock bolt 5, has avoided direct contact; To the device that the major diameter axle head need to be tightened, also be convenient to install.
