SUMMERY OF THE UTILITY MODEL
The utility model provides a take concentric complex screw thread and tie-down piece aims at solving present ordinary screw thread and does not take place to slide in order to make tight fixed screw thread, need use fasteners such as jackscrew, lock nut cooperation locking gasket, and this kind of operating mode needs lock nut and gasket to pair the cooperation and uses, and the dismouting is more loaded down with trivial details. On the other hand, the common thread has a gap, so that the concentricity requirement is difficult to ensure after the thread is screwed.
The utility model is realized in such a way that the screw thread fastening piece with concentric fit comprises a mechanism and a fastening piece connected on the mechanism, wherein the middle position of the fastening piece is provided with a connecting screw thread, the fastening piece is provided with a notch, and the connecting screw thread is divided into two sections by the notch; the inside of fastening piece still has pilot hole and screw hole, pilot hole and screw hole are located respectively the both sides of notch, the pilot hole with the screw hole is corresponding.
Preferably, the fastening piece is further provided with a matching part.
Preferably, the fitting hole has a T-shape.
Preferably, the notch is rectangular.
Preferably, the tightening piece has a T-shape.
Preferably, both ends of the fastening piece are provided with chamfers.
Compared with the prior art, the beneficial effects of the utility model are that: through setting up pilot hole and screw hole, when the user will tightly decide the piece through connecting thread and install in the mechanism, can insert the pilot hole with outside screw to twist into the screw downthehole with the screw, until entering into the mechanism, in order to strengthen tightly deciding being connected with the mechanism, make this device person of facilitating the use install or dismantle, effectively prevent that tight screw from taking place to slide, avoid lock nut and gasket to pair the cooperation and use.
Through setting up cooperation portion, this cooperation can be shaft hole cooperation or taper fit to realize tightly deciding with the concentric of mechanism, this device not only can realize fast that simple screw is tight decides, can also provide reliable concentricity and guarantee.
