Description
Technical field
It is especially a kind of to be used for the anti-displacement pull bar of heavy-duty machinery the present invention relates to the pull bar screw-button technical field of Current Collector Sleave
Synchronous anti-rotation screw-button.
Background technology
At present, the pull bar screw-button of Current Collector Sleave is typically all relatively rotated using screw rod and nut and realizes Linear transmission.In order to prevent
Screw rod or nut produce relative rotation with other workpiece, generally using left-handed and dextrorotation two screw rods, have been screwed into left hand thread and the right side
Revolve the nut of screw thread, such threads turn only needs itself to rotate, while standing screw anti-rotation, rotating nut, screw rod can take in or
Release, the left-handed and nut of dextrorotation two similarly can also be used, the screw rod of left hand thread and right-handed thread is screwed into, while fixing nut
Anti-rotation, rotates screw rod, and nut can also take in or release.
The windproof zip screw-button of the left-and-right spiral button of prior art, particularly crane, needs multi agent cooperation to operate, and work is strong
Degree is big, such as want two screw rods while Linear transmission, then must simultaneously prevent two screw rods from rotating, otherwise screw rod can with nut rotation, because
This place to fixed support there are certain requirements, and left-handed and right-handed thread is driven simultaneously, and such as resistance is small is unable to self-locking or by dynamic load
Lotus, screw rod and nut can loosen, and have a strong impact on the security that heavy-duty machinery is used.
The content of the invention
A kind of synchronous anti-rotation screw-button that the purpose of the present invention is directed to the deficiencies in the prior art and designs, using sliding sleeve with
The anti-rotation component and the anti-rotation structure of nut check of slide bar, as soon as making screw-button only to fix wherein screw rod, can conveniently realize
The synchronous precession or back-out of two screw rods, a people can be rapidly completed operation, and easy to use, reliability is high, effectively increases spiral
Button installs the efficiency for tightening up and loosening process, it is to avoid two ends need to support limitation when pull bar screw-button takes in or releases, and preferably prevent
Loosened between bolts and nuts, preferably resolve palpus two ends when left-and-right spiral button is threaded into or screws out and fix and left-and-right spiral
The key issue that button tension loosens, substantially increases the security that heavy-duty machinery is used.
The object of the present invention is achieved like this：A kind of synchronous anti-rotation screw-button, including left-handed spiral shell button, dextrorotation spiral shell button and spiral shell
Mother, is characterized in that the screw rod of left-handed spiral shell button and dextrorotation spiral shell button is provided with the axial slide opening of sliding sleeve, and its screw rod one end is arranged with ladder
The flange of shape；The sliding sleeve is arranged on the port of axial slide opening and with screw rod to be fixedly connected；The left-handed spiral shell button and dextrorotation
Spiral shell button is arranged on nut two ends and is connected with nut thread, and two axial slide openings and the slide bar being arranged in nut are the company of sliding axially
Connect, rotating nut two screw rods can precession simultaneously or back-out nut；The nut is provided with lock handle；The lock handle is by pin
Axle is arranged on nut both sides and is connected to rotate with nut, when lock handle is fastened on the flange of left-handed spiral shell button or dextrorotation spiral shell button
By nut locking, the relative rotation of nut and left-handed spiral shell button and dextrorotation spiral shell button can be prevented.
The present invention be rapidly completed operation by having a people compared with prior art, and easy to use, reliability is high, effectively carries
Screw-button high installs the efficiency for tightening up and loosening process, it is to avoid two ends need to support limitation when pull bar screw-button takes in or releases,
Prevent from being loosened between bolts and nuts, palpus two ends are fixed and left and right spiral shell when preferably resolving the precession of left-and-right spiral button or screwing out
The key issue that spinner tension loosens, substantially increases the security that heavy-duty machinery is used.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is schematic perspective view of the present invention；
Fig. 3 is use state schematic diagram of the present invention.
Specific embodiment
Refering to 1~Fig. 2 of accompanying drawing, the present invention is made up of left-handed spiral shell button 1, nut 2 and dextrorotation spiral shell button 3, the left-handed He of spiral shell button 1
The screw rod of dextrorotation spiral shell button 3 is provided with the axial slide opening 8 of sliding sleeve 4, and one end of its screw rod is arranged with trapezoidal flange 9；The cunning
Set 4 is arranged on the port of axial slide opening 8 and with screw rod to be fixedly connected；The left-handed spiral shell button 1 and dextrorotation spiral shell button 3 are arranged on nut
2 two ends and it is threadedly coupled with nut 2, two axial slide openings 8, to be in axial sliding connection, rotate spiral shell with the slide bar 5 being arranged in nut 2
Female 2 two screw rods can precession simultaneously or back-out nut 2；The nut 2 is provided with lock handle 6；The lock handle 6 is by bearing pin 7
It is arranged on the both sides of nut 2 and is connected to rotate with nut 2；The sliding sleeve 4 is respectively embedded in left-handed spiral shell button 1 and dextrorotation spiral shell button 3
It is integrated on screw rod and with left-handed spiral shell button 1 and dextrorotation spiral shell button 3, sliding sleeve 4 can only axially slide relative with slide bar 5 and can not rotate.
Refering to accompanying drawing 3, locking anti-rotation of the invention is so to use：When tightening up or loosening, left-handed spiral shell only need to be fixed
One in button 1 or dextrorotation spiral shell button 3, such as fixed left-handed spiral shell button 1, by the rotating nut 2 of lock handle 6, the precession spiral shell of left-handed spiral shell button 1
Female 2.Meanwhile, dextrorotation spiral shell button 3 makes two sliding sleeves 4 be connected by slide bar 5, can only be relative between dextrorotation spiral shell button 3 and left-handed spiral shell button 1
Slide axially and can not mutually rotate.Can mutually axially be slided between sliding sleeve 4 and slide bar 5, equivalent to while fixing two screw rods
Rotation, i.e. dextrorotation spiral shell button 3 is also relatively fixed, and precession nut 2 synchronous with left-handed spiral shell button 1, and two screw rod buttons can synchronously take in
Or release.When nut 2 is rotated in place, lock handle 6 fastens to the locking position of the flange 9 of left-handed spiral shell button 1 or dextrorotation spiral shell button 3
Put, in so left-handed spiral shell button 1 or dextrorotation spiral shell button 3 cannot produce relative rotation and nut 2 between, again by sliding sleeve
4 and slide bar 5 connect, between left-handed spiral shell button 1 and dextrorotation spiral shell button 3 and nut 2 locking can not produce relative rotation, improve screw-button
The efficiency of process is tightened up and loosened in installation, it is to avoid when pull bar screw-button takes in or releases, two ends need to support limitation.By on nut 2
Lock handle 6 up turn over, can as rotation nut 2 when handle, when tightening up or loosening in place, by lock handle 6 down
Turn over and be fastened on flange 9, the loosening between nut 2 and left-handed spiral shell button 1 and dextrorotation spiral shell button 3 can be prevented.
Simply the present invention is further illustrated above, and is not used to limit this patent, and all is equivalence enforcement of the present invention,
It is intended to be limited solely by within the right of this patent.
