     볼트와 너트는 기기와 구조물에 기계적인 요소들을 결합하는데 널리 사용되고있으며 너트의 주된역활은 볼트축방향의 힘을 유지시키는데 있다 
     특히 결합용나사는 접촉면에 마찰력이 발생하여 스스로 풀어지지 않도록 설계되어있으나 진동과 충격을받으면 순간적으로 접촉압력이 감소되어 마찰력이 거의 없어지는 현상이 발생하며 이러한 현상이 반복되면 나사가 풀리게되어 결합된 구조물 및 기기가 해체되어 크나큰 문제가 발생하므로 이러한문제를 해소하기위하여 본 발명의 풀림방지 너트가 제공되는 것이다 
     본 발명의 풀림방지 너트는 육각너트몸체(1)의 육각너트몸체 하부면(5)에서 시작으로 육각너트몸체 상부면(6)까지 밋밋한 경사각을 이루는 나선형으로 홈(2)내측에 형성되어 있는 나사산(3)까지도 관통하여 절개하여 풀림방지 너트의 육각너트몸체(1)는 나선형의 스프링코일(4) 형태로 이루어져 외부에서 주어지는 진동과 충격을 탁월하게 흡수하면서 유동하여 홈(2)내측에 형성되어 있는 나사산(3)과 결합되는 볼트의 나사산과의 접촉면에 마찰력이 강하게 발생하여 밀착되며 접촉압력이 상승되어 너트가 풀어지지않는 기능을 부여한 구조이다 
     또한, 본발명의 풀림방지 너트가 오른쪽으로 조임나사이면 나선형의 스프링코일(4)의 절개선(7)이 시작하는 왼쪽선이 낮으며 오른쪽으로 상승하며 빗각으로 이루어져 외부에서 육각너트몸체(1)에 수직으로 가하는 진동과 충격의 에너지의힘 이 빗각으로 받아 방향이 전환되어 육각너트몸체(1)를 오른쪽으로 회전시키려는 힘이가하지며 고정되기위하여 결합된 풀림방지 너트 조임나사를 더욱 강하게 조여 본 발명의 풀림방지 너트를 제공한다 
     또한.본발명의 풀림방지 너트가 왼쪽으로 조임나사이면 나선형의 스프링코일(4)의 절개선(7)이 시작하는 오른쪽선이 낮으며 왼쪽으로 상승하며 빗각으로 이루어져 외부에서 육각너트몸체(1)에 수직으로 가하는 진동과 충격의 에너지의힘이 빗각으로 받아 방향이 전환되어 육각너트몸체(1)를 왼쪽으로 회전시키려는 힘이 가해지며 고정되기위하여 결합된 풀림방지 너트 조임나사를 더욱 강하게 조여 본 발명의 풀림방지 너트를 제공한다 
     또한,본 발명의 풀림방지 너트의 육각너트몸체(1)는 나선형의 스프링코일(4) 형태를 제공하여 외부에서 주어지는 온도에 의하여 나선형의 길이로 수축팽창하면서 유동하여 홈(2)내측에 형성되어 있는 나사산(3)과 결합되는 볼트의 나사산과의 접촉면에 마찰력을 강하게 발생시켜 밀착되며 접촉압력이 상승되어 너트가 풀어지지않는 탁월한 기능을 부여한 구조가 제공되는것을 특징으로한 풀림방지 너트이다 
       
     풀림방지 너트, 나선형의 스프링코일(4), 절개선(7), 에너지의힘이 빗각으로 받아 방향이 전환, 육각너트몸체(1), 진동과 충격을 탁월하게 흡수, 나사산(3)과 결합되는 볼트의 나사산과의 접촉면에 마찰력이 강하게 발생하여 밀착, 나선형의  스프링코일(4) 형태로 이루어져 외부에서 주어지는 온도에 의하여 나선형의 길이로 수축팽창하면서 유동,
