Abstract

본 발명은 암, 수 나사산에 체결되는 체결용 너트와 볼트에 있어, 체결된 너트 또는 볼트가 임의로 풀리지 않도록 한 기술에 관한 것이다.TECHNICAL FIELD The present invention relates to a fastening nut fastened to female and male threads, and a technique for preventing fastening of a fastened nut or bolt.

종래 체결너트 또는 볼트의 풀림을 방지코자 한 기술로서 와셔를 볼 수 있으나 상기 와셔는 그 효과가 완전하지 못하여 왔다.Conventionally, a washer can be seen as a technique for preventing loosening of a fastening nut or a bolt, but the washer has not been fully effective.

본 발명은 이를 시정코자 하여 체결너트내에 또는 볼트의 나사봉에 권선스프링을 내재시키되 일측은 연동 가능하도록 하고 타측은 고정시켜서 체결시에는 스프링의 원주가 축소 또는 확대되어 체결나사산에서 슬라이드되면서 체결회전되고 역으로 풀 때에는 권선스프링이 체결나사산에 의한 밀림에 의하여 확장 또는 축소되고 더 이상의 확장, 축소가 불가능하게 될 때 회전을 방지하며 체결된 너트 또는 볼트가 역회전 (풀림)이 될 수 없도록 한 너트와, 볼트에 관한 것이다.In the present invention, the coil spring is contained in the fastening nut or the threaded bar of the bolt, and one side is interlocked and the other side is fixed. When the fastening is performed, the circumference of the spring is reduced or enlarged, In reverse, when the coil spring is expanded or contracted due to the tightening by the fastening screw and it is impossible to expand or shrink further, it prevents rotation and prevents the fastened nut or bolt from being reversed , And bolts.

이러한 본 발명은 권선스프링을 권선하되 일측이 고정되고 타측은 연동 됨으로서 체결나사산이 회전할 때에 상기 권선스프링이 나사산과 슬라이드 되는 밀림에 의해 연동부가 이동됨으로 원주가 축소 또는 확장되면서 체결나사산과 압압되어 역회전될 수 없게 하고 풀림방향으로의 회전에서는 체결나사산과 슬라이드되는 스프링이 연동부를 임의의 조작으로 밀어 스프링을 확장 또는 축소하여 체결볼트 또는 너트가 회전할 수 있게 함으로서 효과를 발휘하도록 한 것이다.According to the present invention, the winding springs are wound and one side is fixed and the other side is interlocked. When the fastening thread rotates, the interlocking part is moved by the threading and sliding of the coil spring so that the circumference is reduced or expanded, And in the rotation in the pulling direction, the fastening screw and the spring to be slid are pushed by an arbitrary manipulation by expanding or reducing the spring so that the fastening bolt or nut can rotate.

즉, 계속확장 또는 축소될 수 없는 스프링은 회전되는 풀림나사산의 회전체를 가압하여 회전을 막게되는 풀림방지 목적의 너트와 볼트에 관한 것이다.That is, the spring which can not be continuously expanded or reduced is intended to prevent rotation by pressing the rotating body of the rotating threaded thread.
