The technical scheme that the utility model provides is: this steel work rod member coupling arrangement; Include steel work rod member, base plate, coupling sleeve, forward coupling head, reverse coupling head, positive lock jack panel, reverse locking nut, locking pin; Be characterized in that the said first steel work rod member and first base plate link, first base plate and forward coupling head link, and an end of forward coupling head and coupling sleeve links; The other end of coupling sleeve links with reverse coupling head; The reverse coupling head and second base plate link, and second base plate and the second steel work rod member link, and an end of said coupling sleeve is provided with the positive lock jack panel; The other end of said coupling sleeve is provided with reverse locking nut, respectively is provided with a locking pin on the two ends of said coupling sleeve.
For better accomplishing the purpose of the utility model, the inner chamber of said coupling sleeve has positive and negative two kinds of screw threads, and the two ends of coupling sleeve are threaded the hole.
For better accomplishing the purpose of the utility model, an end of said forward coupling head has the forward external screw thread, and the end of thread of forward coupling head has the restraint groove.
For better accomplishing the purpose of the utility model, an end of said reverse coupling head has reverse external screw thread, and the end of thread of reverse coupling head has the restraint groove.
For better accomplishing the purpose of the utility model, said positive lock jack panel has the forward internal thread, and the positive lock jack panel also has blind hole.
For better accomplishing the purpose of the utility model, said reverse locking nut has reverse internal thread, and reverse locking nut also has blind hole.
Compare with prior art; The beneficial effect of the utility model is: the utility model material therefor is simply common; Mechanical processing technique is simple, and is easy to operate, reasonable in design; Can solve effectively mounting process complicacy, waste material, adjusting range that prior art exists little, adapt to and process and problems such as construction error ability, have characteristics quick for installation, easy to adjust, safe and reliable, applied range.It is mainly reflected in the following aspects.
1. the positive and negative end of thread of coupling sleeve is corresponding with the forward and reverse coupling head with positive and negative screw thread respectively; The forward and reverse coupling head that when the branch sleeve forward rotation, can drive two ends screws in simultaneously, and the forward and reverse coupling head that can drive two ends during backward rotation screws out simultaneously.
2. when the rotation coupling sleeve was adjusted to rational position with the steel work rod member, the locking nut of the end of screwing limited the rotation between coupling sleeve and the forward and reverse coupling head.
3. the screw-in locking pin is stuck in the locking groove of forward and reverse coupling head its end, strengthens the restriction to rotating between coupling sleeve and the forward and reverse coupling head.
4. forward and reverse coupling head has the characteristic of in coupling sleeve, rotating arbitrarily, and this characteristic makes the variation of angle between two steel work rod members have no effect to each parts of this system of connections, has fully guaranteed the versatility of this system of connections.
5. this kind system of connections can also be expanded it, increases the ornamental and bulk strength that drag-line or Tiebar structure satisfy steel work.
6. can accomplish very accurate through ridge apart from distance and angle between two steel work rod members of adjustment.Being connected between base plate and the steel work rod member can be that to weld also can be to be spirally connected, and all in factory, accomplishes, and positioning accuracy is high, and construction quality is good.
7. forward and reverse locking nut outer face is provided with the blind hole of certain angle, applicable to the clamping of standard spanner, makes it better to play the locking effect.
