Steel bar straight thread sleeve connecting device

Abstract

The utility model relates to the technical field of building construction, in particular to a steel bar straight thread sleeve connecting device which comprises a first supporting ring and a second supporting ring which are coaxially connected in a sleeved mode, and the first supporting ring and the second supporting ring can rotate relatively. First supporting rods are arranged on the side face of the first supporting ring in an up-down opposite mode, threaded sleeve lifting bases are arranged on the first supporting rods in a sliding mode, and a first hose clamp is movably arranged between the threaded sleeve lifting bases in a penetrating mode. Second supporting rods are arranged on the side face of the second supporting ring in an up-down opposite mode, steel bar lifting bases are arranged on the second supporting rods, a second hose clamp is movably arranged between the steel bar lifting bases in a penetrating mode, and a target plate part is arranged on one second supporting rod in a sliding mode and located between the second supporting ring and the steel bar lifting bases. The label plate part comprises a label plate sliding seat movably arranged on the second supporting rod, a label plate lifting seat is vertically and slidably arranged at the bottom of the label plate sliding seat, label plates are vertically and oppositely arranged at the bottom of the label plate lifting seat, and the distance between the label plates is not larger than the distance between every two adjacent threads in the screw threads. Workers do not need to frequently and visually inspect the exposed screw thread condition in the connecting process, trouble and labor are saved, and the connecting efficiency is improved.
