Claims (1)
中央にボルトを植立し、プラグ上端に設けられる溝に０
リングパツキンを装置しボルトに遊嵌する押え板の下面
はスペーサを介してボルトの上部ねじに螺合するハンド
ルの回転に伴う力で０リングパツキンを圧縮しねじ逃げ
部に圧着させる構造を特徴とする胴体フランジねじ穴防
水プラグの構造。A bolt is planted in the center of the plug that contacts the inclined part of the screw hole and loosely fits into the screw relief part, and a bolt is inserted into the groove provided at the upper end of the plug.
The lower surface of the retaining plate that mounts the ring fitting and loosely fits onto the bolt is characterized by a structure in which the O-ring fitting is compressed by the force associated with the rotation of the handle, which is screwed into the upper screw of the bolt via a spacer, and is crimped onto the screw clearance part. The structure of the fuselage flange screw hole waterproof plug.
