成されている。In this conventional connecting device, fitting portions for fitting a scaffolding pipe are formed at both ends of a connecting tubular body, and a pair of through holes are formed in opposing peripheral walls at the center. . A substantially L-shaped locking rod is movably penetrated through the through-hole of the connecting cylindrical body, and a tip of the locking rod can be engaged with an engaging hole of a scaffold pipe fitted to one of the fitting portions. The locking portion is bent.

ップの内側端部とに係止されている。[0004] Among the pair of through holes on the connecting cylinder, the through hole on the side corresponding to the base end of the locking rod is formed to be larger in diameter than the other through hole. A compression spring is fitted to the locking rod through a large-diameter through hole of the connecting cylinder, and a retaining cap having an inner diameter substantially equal to the outer diameter of the locking rod is fitted to the proximal end of the locking rod. Is being worn. Then, the peripheral wall of the retaining cap is fixed to the locking rod by caulking, so that the locking rod is retained in a state of being penetrated through the through hole, and both ends of the compression spring are connected to the connecting cylindrical body. It is locked on the inner peripheral surface and the inner end of the retaining cap.
【０００５】[0005]
【発明が解決しようとする課題】ところが、この従来の
足場用パイプの連結具においては、次のような問題があ
った。However, this conventional scaffolding pipe connector has the following problems.

ーズに移動させることができなかった。That is, since the retaining cap is fixed to the locking rod by caulking on the peripheral wall and is inserted into the large-diameter through hole of the connecting cylinder, the outer peripheral surface of the cap is deformed and deformed during caulking. And the locking rod could not be moved smoothly.
【０００７】また、圧縮バネの両端が連結筒体の内周面
と抜け止めキャップの内側端部とに係止されるようにな
っているため、圧縮バネの長さが短くなって、錠止杆を
移動付勢するための強い付勢力を確保することができな
かった。Further, since both ends of the compression spring are engaged with the inner peripheral surface of the connecting cylinder and the inner end of the retaining cap, the length of the compression spring is shortened and the compression spring is locked. A strong biasing force for moving and biasing the rod could not be secured.

杆が回転して、錠止杆の錠止部を嵌合部に嵌合された足
場用パイプの係合孔に係合させるのが困難であった。In addition, since the locking rod is freely rotatable in a state of being inserted through the through-hole of the connecting cylinder,
When the locking rod is moved against the urging force of the compression spring, the locking rod rotates, and the locking part of the locking rod is engaged with the engaging hole of the scaffold pipe fitted in the fitting part. It was difficult to match.

あって、その操作が非常に面倒であった。In addition, since the tip of the locking portion of the locking rod is a flat surface extending in a direction orthogonal to the axis, the fitting of the scaffolding pipe to one fitting portion of the connecting tubular body is difficult. It was necessary to move the locking rod against the urging force of the compression spring to retract the locking part to a position where it did not interfere with the edge of the scaffold pipe, which was very troublesome. .
