Description
제 1a도는 본 고안의 측면도.Figure 1a is a side view of the present invention.
제 1b도는 본 고안의 정면도.Figure 1b is a front view of the present invention.
제 2a도-제 2c도는 본 고안의 나사로 부품에 고정된 상태의 단면도.2a to 2c is a cross-sectional view of a state fixed to the component with a screw of the present invention.
본 고안은 부품간을 고정하는 나사에 관한 것으로서 특히 나사축을 다수개로 갈라지게 하고 갈라진 나사축의 가운데 부분을 구부려서 내부가 공간이 되도록 한 나사의 구성에 관한 것이다.The present invention relates to a screw for fixing between parts, and more particularly, to the configuration of the screw to be divided into a plurality of screw shafts and bent the middle portion of the split screw shaft to the interior space.
종래의 부품들을 고정한 나사들은 진동에 의해서 풀리지 않게 하려고 나사에 락카등을 칠해두던가 풀림방지용 와셔등을 사용해서 고정시켜야 했고 또 나사를 자주 풀었다 조였다 하는 경우에는 나사선이 헐거워져서 쉽게 풀리게 될 염려가 있없다.Screws fixing the conventional parts should be fixed by applying a locker or the like to prevent them from being loosened by vibration, or by using a washer-proof washer, etc. If the screws are frequently loosened and tightened, the screws may loosen and be easily loosened. none.
본 고안은 이와같은 점을 감안하여 제품에 고정된 나사는 진동에 의해서도 풀리지 않도록 하고, 또 나사를 자주 조였다 풀어도 나사산이 헐거워질 염려가 없도록 한 것이다.In view of the above, the present invention does not allow the screw fixed to the product to be loosened by vibration, and there is no fear of loosening the screw thread even if the screw is frequently tightened and released.
본 고안의 구성 및 작용 효과를 상세히 설명하면 다음과 같다.Referring to the configuration and effect of the present invention in detail as follows.
본 고안의 나사는 제 1 도와 같이, 나사(1)의 축방향으로 갈라진 다수개의 나사축(2)의 중간 부위가 외측으로 만곡져서 나사축(2) 사이에 공간부(3)를 형성하여서 된 것이다.The screw of the present invention is formed by forming a space 3 between the screw shafts 2 by bending the middle portions of the plurality of screw shafts 2 split in the axial direction of the screw 1, as in the first diagram. will be.
미설명 부호 4: 나사산, 5 : 나사머리, 6: 부품의 판, 7 : 부품의 몸체, 8 : 나사구멍이다.Reference numeral 4: thread, 5: screw head, 6: plate of the component, 7: body of the component, 8: screw hole.
본 고안의 작용 효과는 제 1 도와 같이 나사축(2)은 다수개로 갈라져 있고 그 사이에는 공간부(3)가 형성되어 있기 때문에 나사축(2)은 강력한 탄력성을 갖게 된다.The working effect of the present invention is that the screw shaft (2) is divided into a plurality, like the first degree, and the space between the space (3) is formed between the screw shaft (2) has a strong elasticity.
따라서 제 2a도와 같이 나사(1)로 고정할 판(6)의 나사구멍(8)에 나사(1)의 끝을 끼우고 조이기 시작하면 갈라진 나사축(2)들이 내측 공간부(3)쪽으로 점점 오무라들면서 나사(1)가 제 2b도와 같이 조여져셔 고정되는데 이때 나사축(2)들이 만곡져서 직경이 커진 중간부위가 나사구멍(8)에 위치되었을 때 나사축(2)들이 가장 많이 오라들게 된다. 그리고 제 2b도와 같이 나사(1)를 판(6)에 고정하면 나사축(2)들은 공간에서 최대로 벌어지게 되고, 이때에는 나사(1)의 중간부위의 직경이 판(6)의 나사구멍(8)에 끼워져 있는 부분의 직경보다 커지게 될뿐 아니라 나사축(2)들의 자체탄성력에 의해 나사(1)가 구멍(8) 속에 꼭 끼워지게 된다.Accordingly, when the end of the screw 1 is inserted into the screw hole 8 of the plate 6 to be fixed with the screw 1 as shown in FIG. 2A and the screw thread is started to tighten, the divided screw shafts 2 gradually become toward the inner space 3. The screw shaft 1 is tightened and fixed as shown in Fig. 2b while the screw shaft 2 is bent so that the screw shaft 2 can be lifted the most when the middle part having the larger diameter is positioned in the screw hole 8 while being pulled out. do. When the screw 1 is fixed to the plate 6 as shown in FIG. 2B, the screw shafts 2 are opened to the maximum in the space. In this case, the diameter of the middle portion of the screw 1 is the screw hole of the plate 6. Not only is it larger than the diameter of the part fitted in (8), but also the screw 1 is tightly fitted in the hole 8 by the self-elasticity of the screw shafts 2.
제 2c도는 부품 몸체속에 나사가 고정된 상태의 단면도로서 이때는 나사축(2)들이 서로 오무라져서 외측으로 만곡된 부분이 거의 직선상으로 되어서 나사축들은 나사구멍에서 강력하게 탄지되는 것이다.FIG. 2C is a cross-sectional view of the state in which the screw is fixed in the body of the component. At this time, the screw shafts 2 are folded together so that the outwardly curved portion becomes almost straight and the screw shafts are strongly supported in the screw holes.
나사(1)를 뺄때에는 상기와 반대의 작용이 이루어지게 된다.When the screw 1 is pulled out, the opposite operation is performed.
이와같이 본 고안은 진동에 의한 나사의 풀림도 방지되고 또 나사를 자주 조였다 풀었다해도 나사가 자체 탄성력을 유지하므로 반복사용이 가능하여 나사의 수명도 길어지게 된 것이다.As such, the present invention also prevents loosening of the screw due to vibration, and even though the screw is frequently tightened and loosened, the screw maintains its own elastic force, so that the screw can be used repeatedly, thereby increasing the life of the screw.
또한 본 고안의 나사은 직경이 변하기 때문에 나사구멍이 꼭맞지 않더라도 사용할 수 있고, 별도의 부재없이 나사만 끼우면 풀림방지가 되므로 나사 고정된 부품의 안정성을 높인 것이다.In addition, the screw of the present invention can be used even if the screw hole does not fit because the diameter is changed, it is to increase the stability of the screw fixed parts because it is prevented to loosen just insert the screw without a separate member.
