Connecting device and steel bar connecting system

Abstract

The utility model provides a connecting device and a steel bar connecting system.The connecting device comprises a first connector, a second connector and a sleeve, one end of the first connector is suitable for being detachably connected with the end of a bar, the other end of the first connector is provided with a first annular flange, and the first annular flange extends along the peripheral side of the first connector; one end of the second connector is suitable for being detachably connected with the end of another bar, and external threads are arranged on the peripheral side of the second connector. A through hole is formed in the sleeve so that the sleeve can be arranged on the peripheral side of the first connector in a sleeving mode, a second annular flange is arranged at one end of the inner wall of the through hole, a first internal thread is further arranged on the inner wall of the through hole, and the first internal thread can be screwed with the external thread so that when the first annular flange abuts against the second connector, the second annular flange can abut against the second connector. And the first joint is connected with the second joint through the second annular flange. The connecting device has the advantages of being convenient to reuse and high in connecting strength. 本申请提供了一种连接装置和钢筋连接系统，连接装置包括第一接头、第二接头和套筒，第一接头的一端适于与棒料的端部可拆卸地相连，第一接头的另一端设有第一环形凸缘，第一环形凸缘沿第一接头的外周侧延伸；第二接头的一端适于与另一棒料的端部可拆卸地相连，第二接头的外周侧设有外螺纹；套筒内设有通孔以使套筒可套设于第一接头的外周侧，通孔内壁的一端设有第二环形凸缘，通孔的内壁还设有第一内螺纹，第一内螺纹可与外螺纹旋和，以在所述第一环形凸缘与所述第二接头相抵时，通过所述第二环形凸缘将所述第一接头与所述第二接头相连。本申请提供的连接装置具有便于重复利用、连接强度较高的优点。
