이를 좀더 구체적으로 설명하면, 캡(50)의 수납부(51)내에 너트(30)가 위치하지 않은 상태에서는 도 4a 에 도시된 바와 같이 너트고정부재(60)인 너트고정편(62)은 자체의 텐션력을 갖고 있는 상태에서 선단부가 상부를 향하는 소정의 경사각을 유지하고 있게 된다.More specifically, when the nut 30 is not located in the accommodating portion 51 of the cap 50, the nut fixing piece 62, which is the nut fixing member 60, as shown in FIG. 4A is itself. The tip portion maintains a predetermined inclination angle toward the upper portion with a tension force of.
이러한 상태에서 캡(50)의 수납부(51) 부분이 너트(30) 상면에 위치하도록 하면, 경사각을 갖고 있는 너트고정편(62)의 선단 일부분이 너트(30)에 얹혀진 상태를 유지하게 된다.In such a state, when the housing 51 of the cap 50 is positioned on the upper surface of the nut 30, the tip portion of the nut fixing piece 62 having the inclination angle is maintained on the nut 30. .
상기와 같은 상태에서 캡(50)에 인위적인 힘을 가하여 하부로 눌러주게 되면 가해지는 힘에 의해 도 4b 에 도시된 바와 같이 너트(30)의 상면에 얹혀져 있는 너트고정편(62)이 자체의 텐션력에 의해 선단부분이 상부로 휘어지면서 캡(50)이 하부로 이동하게 된다.In the above state, when the artificial force is applied to the cap 50 and pressed downward, the nut fixing piece 62 mounted on the upper surface of the nut 30 by the applied force is tensioned by itself. Cap 50 is moved downward while the tip portion is bent upward by the force.
상기와 같은 상태로 하여 캡의 하단면이 구조물(10)의 상면에 접할 때까지 눌러주면 되는 것으로서, 너트고정편(62)은 자체의 텐션력에 의해 원상태로 복귀하려는 힘이 발생됨에 따라 각각의 너트고정편(62) 선단면이 도 5 에 도시된 바와 같이 너트(30)의 각면 또는 모서리 부분에 탄지된 상태를 유지하게 된다.It is to be pressed until the bottom surface of the cap in contact with the upper surface of the structure 10 in the same state as described above, the nut fixing piece 62 has a force to return to its original state by the tension force of each The tip end face of the nut fixing piece 62 is maintained on the surface or edge portion of the nut 30 as shown in FIG. 5.
상기에서와 같이 너트(30)의 외주연에 캡(50)이 씌워진 상태에서 사용을 하게 되면 외부로부터 빗물이나 눈 또는 각종의 이물질이 너트(30)와 나선축(21)에 뭍지않게 되는 것이다.As described above, when the cap 50 is used on the outer circumference of the nut 30, rain water, snow, or various foreign matters do not stick to the nut 30 and the spiral shaft 21 from the outside.
또한, 상기와 같이 너트(30)에 보호캡(50)이 씌워진 상태에서 사용을 하다가 인위적인 힘으로 너트(30)를 풀고자 할 경우 너트(30)를 씌워주고 있는 캡(50) 벗겨주어야 하는데, 상기 너트(30)에 씌워져 있는 캡(50)을 상부로 잡아 당겨주게 되면 외주연은 캡(50)의 요입홈부(52)내에 위치하고 있는 회전링(61)의 내주면에 일체로 연장시켜 자체의 텐션력에 의해 상부를 향하여 강제로 휘어진 상태에서 선단면이 너트(30)의 외면에 탄지되어 있는 너트고정편(62)에 의하여 너트(30)에 씌워져 있는 캡(50)이 빠지지 않게 되는 것이다.In addition, while using the protective cap 50 on the nut 30 as described above, if you want to loosen the nut 30 by artificial force, the cap 50 covering the nut 30 should be peeled off. When the cap 50 covered by the nut 30 is pulled upward, the outer circumference is integrally extended to the inner circumferential surface of the rotary ring 61 located in the recess 52 of the cap 50 so as to have its own tension. The cap 50 covered by the nut 30 is prevented from being pulled out by the nut fixing piece 62 in which the front end face is supported on the outer surface of the nut 30 in a state of being forced upward by the force.
이러한 경우 너트(30)를 잡아주고 있는 보호캡(40)을 회전시켜 이에 잡혀져 있는 너트(30)를 나선축(21)으로부터 풀어주기 위하여 캡(50)을 회전시켜 주게 되는데, 이때 상기 캡(50)은 너트(30)를 잡아주고 있는 너트고정부재(60)인 회전링(61)이 캡(50)의 내주연에 갖추어져 있는 요입홈부(52)내에 끼워진 상태에서 임의 회전이 가능하도록 되어 있으므로서, 너트고정부재(60)는 너트(30)를 잡아주고 있는 상태에서 캡(50)만이 임의 회전을 하게 됨에 따라 너트(30)를 풀어주지 못하게 되는 것이다.In this case, by rotating the protective cap 40 holding the nut 30, the cap 50 is rotated to release the nut 30 held therefrom from the spiral shaft 21. In this case, the cap 50 Since the rotating ring 61, which is the nut fixing member 60 holding the nut 30, is inserted into the recess groove 52 provided on the inner circumference of the cap 50, arbitrary rotation is possible. , The nut fixing member 60 is not able to loosen the nut 30 as only the cap 50 is rotated in the state holding the nut 30.
