RETAINING STRUCTURE OF CONNECTION PIN
To provide a retaining structure of a connection pin which is simple in structure and is capable of improving assembly property in a narrow space.SOLUTION: A retaining structure is applied to a pin connection portion of a construction machine and retains a connection pin 23 in a state in which the connection pin and connection members 21, 22 having pin insertion holes are detachably fitted together. Since the connection pin includes a pin body 24 extending in an axial direction and a flange 25 provided on an outer peripheral portion of one axial end of the pin body, and a bolt insertion hole 24a penetrating the pin body in the axial direction is provided, a cap 26 arranged at the other end in the axial direction can be fastened to the pin body with a bolt 27 inserted from the one end side in the axial direction. The flange has a tool engaging portion 25a restricting a rotation of the connection pin. The cap is formed in a disk-like shape with a diameter larger than that of the pin body, and has a rotation restricting portion that restricts relative rotation with the pin body when the bolt is temporarily tightened.SELECTED DRAWING: Figure 2
【課題】簡単な構造でありながら、狭小部における組立性の向上を図ることが可能な連結ピンの抜け止め構造を提供する。【解決手段】建設機械のピン結合部に施され、連結ピン２３と、ピン挿通孔を有する連結部材２１，２２とを挿脱可能に嵌合した状態で、連結ピンの抜け止めを行う抜け止め構造において、連結ピンは、軸方向に延びるピン本体２４と、該ピン本体の軸方向一端外周部に設けられたフランジ２５とを有し、ピン本体を軸方向に貫くボルト貫通孔２４ａが設けられることで、軸方向他端に配されるキャップ２６を軸方向一端側から挿入したボルト２７でピン本体に締結可能に構成してなり、フランジは、連結ピンの回転を規制する工具係合部２５ａを有し、キャップは、ピン本体よりも大径の円板状に形成され、ボルトの仮締め状態で、ピン本体との相対回転を規制する回転規制部を有している。【選択図】図２
