摘要：
An object of the present invention is to provide a duplex threaded body having a right-handed thread and a left-handed thread on the circumferential surface of a single solid member. In addition, an object of the present invention is to provide a single-nut or double-nut type internally-threaded body that demonstrates a locking effect even at an intermediate position without substantially loosening by using a combination of a duplex externally-threaded body and one or more internally-threaded bodies. Moreover, an object of the present invention is to provide a screw structure in which a pair of internally-threaded bodies can only be removed by destruction once they are mutually coupled when screwed onto a duplex externally-threaded body, thereby making it possible to impart tamper-proof characteristics in addition to a locking effect. The duplex externally-threaded body of the present invention has, on the outer circumferential surface of a rod-like member, an overlapping region in which a clockwise spiral right-handed thread and a counter-clockwise spiral left-handed thread are provided in at least an overlapping manner. Moreover, the present invention makes it possible to use, alone or in combination, a right-handed internally-threaded body in which a right-handed thread is formed, and a left-handed internally-threaded body in which a left-handed thread is formed, that are screwed onto a duplex externally-threaded body.
摘要（中）：
本发明的目的是提供一种在单个实心构件的圆周表面上具有右旋螺纹和左旋螺纹的双面螺纹体。 此外，本发明的目的是提供一种单螺母或双螺母型内螺纹体，即使在中间位置也显示出锁定效果，而基本上不会松动，因此使用双面外螺纹体和 一个或多个内螺纹体。 此外，本发明的目的是提供一种螺钉结构，其中一旦在螺纹连接到双面外螺纹体上相互联接时，一对内螺纹体只能通过破坏而被去除，从而可以赋予 防篡改特性除锁定效果外。 本发明的双面外螺纹体在棒状构件的外周面上具有重叠区域，在该区域中设有顺时针螺旋式右旋螺纹和逆时针旋转的左旋螺纹 最不重要的方式。 此外，本发明可以单独使用或组合使用形成右旋螺纹的右旋内螺纹体和左旋内螺纹体，其中左旋螺纹 被形成，其被拧到双面外螺纹体上。
