    • PROBLEM TO BE SOLVED: To provide a meter gas plug capable of manufacturing a mechanism for regulating a fully closed position and preventing turn from the position inexpensively by a simple structure.
      SOLUTION: A protruding part 25 is formed by substantially 180° in the circumferential direction at an upper part opening fringe 24 of a gas plug main body 2, and a bolt 6 for regulating fully closed position capable of moving vertically and a bolt 7 for preventing turn at an opposing position apart by substantially 180° are provided on a handle 4, respectively. The bolt 6 for regulating fully closed position is moved downward in advance and bumps against a collision prevention wall 25R or 25L on one side of the protruding part 25. A plug body 3 is turned to regulate a fully closed position. At this time, the bolt 7 for preventing turn is positioned on the collision prevention wall 25L on the other side apart by substantially 180° and is moved until it is locked in the collision prevention wall 25L on the other side to prevent turn of the plug body 3 in the forward and reverse directions.

    • 要解决的问题:提供一种能够制造用于调节完全关闭位置的机构的仪表气塞,并且通过简单的结构来廉价地防止从该位置的转向。 解决方案:突出部分25在气塞主体2的上部开口边缘24处沿圆周方向大致180°形成,并且用于调节能够垂直移动的完全关闭位置的螺栓6和螺栓 在手柄4上分别设置有用于防止在相对位置上分开大致180°的转动的7。 用于调节完全关闭位置的螺栓6预先向下移动,并且突出抵靠在突出部分25的一侧上的防碰撞壁25R或25L。塞体3被转动以调节完全关闭位置。 此时,用于防止转弯的螺栓7位于另一侧的防碰撞壁25L上大致180°,并且移动直到其锁定在另一侧的防碰撞壁25L中,以防止插头 身体3在正反方向。 版权所有(C)2007,JPO&INPIT
