In eliminating the thread tolerance generated between third inner sleeve external screw thread and the second inner sleeve internal screw thread, third inner sleeve and the are prevented
Two inner sleeves loosen.
Further, the guide head is spherical or taper.Guide function is formed, it under external force can be to bias just
It corrects.
Further, the outer wall section of the connection sleeve is hexagon or dodecagon.It will for external tightening tool
Connection collet head screws well.
Further, the exposed outer wall section of second inner sleeve is polygon or round.It is tightened for outside
Second inner sleeve is clipped and is screwed by tool.
Further, the guide head outer ring is equipped with a circle and the second inner sleeve end generates the step of face contact.
The beneficial effects of the present invention are:
1, by the third inner sleeve that is screwed at connection II male end of reinforcing bar in the present invention, by the length of rebar junction
The external screw thread that compensation rides in third inner sleeve drum outer wall is adjusted, and the external screw thread exposed section of connection reinforcing bar II is avoided brittleness occur
The case where fracture.
2, the external screw thread for connecting reinforcing bar I is all screwed in the present invention in the center counter sink of the first inner sleeve, the company of avoiding
It connects the external screw thread exposed section at reinforcing bar I and the case where brittle fracture occurs.
3, it can realize that reinforcing bar cannot turn by the adjustable high-strength steel bar connector that five component combinations are formed in the present invention
It is attached in the case where dynamic, and can be realized by guide head and bias is adjusted automatically in the case that reinforcing bar is eccentric, and can
It realizes and compensates adjustment in the case that reinforcing bar length is inconsistent, it can be to realize that high tensile reinforcement connection meets I grade of connection of country
Standard.
