Description

탄성 셀프 록킹너트{ A Self Locking Nut }Elastic Self Locking Nut {A Self Locking Nut}

본 발명은 탄성력을 이용한 셀프 록킹 너트에 관한 것으로서, 특히, 셀프 록킹너트가 가압물에 접촉되는 부분에 요홈부를 갖는 걸림턱을 형성하고, 이 걸림턱내에 걸림요홈이 걸려지도록 일체형와셔를 설치하여 너트를 조일 때, 일체형 와셔가 연결링을 가압하여 연질링이 볼트의 외측면을 강하게 가압하여 고정시키므로 반복하여 너트를 사용하더라도 체결력이 약화되는 것을 방지하도록 하는 탄성 셀프 록킹너트에 관한 것이다.The present invention relates to a self-locking nut using an elastic force, and in particular, a locking jaw having a recessed portion is formed in a portion where the self-locking nut contacts the pressurized object, and an integral washer is installed so that the locking recess is caught in the locking jaw. When tightening, the integral washer relates to an elastic self-locking nut that presses the connection ring so that the soft ring strongly presses and fixes the outer surface of the bolt, thereby preventing the tightening force from weakening even if the nut is repeatedly used.

일반적으로, 볼트(Bolt)와 너트(Nut)는 서로 다른 부품을 연결하기 위하여 사용되는 체결수단으로서, 볼트의 나사산에 체결되는 너트의 조임력에 의하여 조립된 부품이 진동이 가하여지더라도 이탈이 되는 것을 방지하도록 한다.In general, the bolt and nut are fastening means used to connect different parts, and the parts assembled by the tightening force of the nut fastened to the thread of the bolt are separated even if vibration is applied. Prevent it.

통상적으로 자동차 부품에는 너트와 볼트를 이용하여 서로 체결하는 부품이 상당하게 많으며, 너트를 볼트에 체결하기 전에 너트가 진동에 의하여 볼트에서 분리되는 것을 방지하기 위하여 너트가 체결물에 접촉되는 부분에 고무링 혹은 와셔등을 사용하여 너트가 접촉물에 밀착 되도록 하여 이탈되는 것을 방지하게 된다.Typically, there are many parts that are fastened to each other by using nuts and bolts in automobile parts, and before the nut is fastened to the bolts, rubber is used to contact the fasteners to prevent the nut from being separated from the bolts by vibration. A ring or washer is used to keep the nut in close contact with the contact to prevent it from falling off.

그러나, 볼트와 너트가 아무리 견고하게 결합되더라도 진동이 지속적으로 가하여 지는 경우, 결국에는 너트가 볼트에서 분리되어 부품이 풀려지는 상태가 발생한다면 치명적인 사고로 이어질 수 있는 문제를 지닌다.However, even if the bolt and the nut is firmly coupled, if the vibration is continuously applied, there is a problem that can lead to fatal accidents if the nut is separated from the bolt and the component is released.

특히, 차량의 부품중에서 스트러트(Strut)는 볼트와 너트의 풀림이 발생하게되면 차량이 전복등과 같은 치명적인 사고를 유발하는 경우도 발생할 수 있다.In particular, among the parts of the vehicle, the strut may cause a fatal accident such as a rollover when the bolt and nut are loosened.

이러한 것을 감안하여 너트가 볼트에서 쉽게 풀려지는 것을 방지한 셀프 록킹너트(Self Locking Nut)를 사용하고 있는 것으로서, 도 1은 종래의 셀프록킹 너트의 구성 단면에 관한 것이고, 도 2는 종래의 셀프록킹 너트의 조립 상태 단면을 보인 도면이다.In view of this, a self-locking nut is used which prevents the nut from being easily released from the bolt. FIG. 1 relates to a cross section of a conventional self-locking nut, and FIG. 2 shows a conventional self-locking nut. Figure showing the assembled state of the nut.

종래의 셀프 록깅 너트(1)의 구성을 살펴 보면, 몸체(2)의 내면에 나사공(3)과 암나사산(4)이 형성되어져 있으며, 가압물(9)에 접촉되는 반대측의 내면에 링설치홈(6)이 형성되어진다.Looking at the configuration of the conventional self-locking nut (1), the threaded hole (3) and female thread (4) is formed on the inner surface of the body (2), the ring on the inner surface of the opposite side in contact with the pressurized material (9) The installation groove 6 is formed.

상기 링설치홈(5)에는 나사공(3)의 내경보다 내경이 작은 연질 상태의 연질링(6)을 설치하도록 한다.The ring installation groove (5) is to install a soft ring (6) of the soft state of the inner diameter is smaller than the inner diameter of the screw hole (3).

이러한 상태에서 도 2에 도시된 바와 같이, 조립을 진행하게 되면, 너트(1)가 볼트(7)에 체결되면서 내경이 작은 연질링(6)이 볼트(7)의 외주면에 압축되어 파손되면서 볼트(7)의 나사산에 밀착되어져 견고하게 조립이 이루어지게 된다.In this state, as shown in FIG. 2, when the assembly is performed, the nut 1 is fastened to the bolt 7 and the soft ring 6 having a small inner diameter is compressed on the outer circumferential surface of the bolt 7 and broken. It is in close contact with the screw thread of (7) and the assembly is made firmly.

그런데, 종래의 셀프록킹너트(1)의 경우에는 앞에서 상세하게 설명한 바와 같이, 일단이 조립이 이루어지면 연질링(6)은 파손되어져 나사산이 형성된 상태로 있게 되므로 너트를 분해하여 재차 조립하는 경우에는 연질링(6)이 볼트(7)의 외주면에 가하는 가압력이 약화되어져서 너트(1)가 진동에 의하여 쉽게 풀어지는 문제를 지닌다.However, in the case of the conventional self-locking nut (1), as described in detail above, the soft ring (6) is broken when one end is assembled, so that a screw thread is formed, so when disassembling and reassembling the nut The pressing force applied to the outer circumferential surface of the bolt 7 by the soft ring 6 is weakened, so that the nut 1 is easily loosened by vibration.

본 발명은 이러한 점을 감안하여 안출한 것으로서, 셀프 록킹너트가 가압물에 접촉되는 부분에 요홈부를 갖는 걸림턱을 형성하고, 이 걸림턱 내에 걸림요홈이 걸려지도록 일체형와셔를 설치하여 너트를 조일 때, 일체형 와셔가 연결링을 가압하여 연질링이 볼트의 외측면을 강하게 가압하여 고정시키므로 반복하여 너트를 사용하더라도 체결력이 약화되는 것을 방지하는 것이 목적이다.The present invention has been made in view of this point, when the self-locking nut is formed in the engaging jaw having a concave portion in the portion in contact with the pressurized water, and when the integral washers are installed so that the engaging groove is caught in the engaging jaw to tighten the nut In order to prevent the fastening force from weakening even if the nut is repeatedly used, the integral washer presses the connection ring and the soft ring strongly presses and fixes the outer surface of the bolt.

본 발명의 구성은, 몸체(12)에 상,하로 관통되는 나사공(14)을 형성하고, 이 나사공(14)의 내벽면에 암나사산(16)을 형성하는 셀프록킹너트에 있어서, 상기 몸체(12)에서 가압물(50)에 접촉되는 부분에 요홈부(18)를 갖는 걸림턱(17)을 형성하고, 상기 걸림턱(17)에 요홈부(18)에 의하여 걸려지는 일체형와셔(20)를 설치하여 너트 조립시 일체형와셔(20)가 연결링(24)을 가압하도록 구성된다.In the constitution of the present invention, in the self-locking nut which forms a threaded hole 14 penetrating up and down in the body 12, and forms an internal thread 16 on the inner wall surface of the threaded hole 14, An integrated washer (17) having a recess (18) having a recess (18) is formed in a portion of the body (12) that is in contact with the pressurized product (50), and the integral washer (110) is fastened by the recess (18). 20) the integral washer 20 is configured to press the connection ring 24 when assembling the nut.

그리고, 상기 몸체(12)의 걸림턱(17)은, 연질링(24) 및 일체형와셔(20)를 삽입한 후에 끝단부를 내측으로 구부려서 일체형와셔(20)가 이탈되는 것을 방지하도록 한다.Then, the locking jaw 17 of the body 12, after inserting the soft ring 24 and the integral washer 20 to bend the end portion inward to prevent the integral washer 20 from being separated.

이하, 첨부도면에 의거하여 본 발명의 작용 및 효과를 상세하게 살펴 보도록 한다.Hereinafter, the operation and effects of the present invention will be described in detail with reference to the accompanying drawings.

도 4 및 도 5에 도시된 바와 같이, 본 발명의 조립 상태를 살펴 보면, 도 5에 표시된 바대로 탄성셀프록킹너트(10)를 화살표 방향으로 조여 주게 되면, 몸체(12)의 걸림턱(17)에 걸려진 일체형와셔(40)가 눌려지게 된다.As shown in Figure 4 and 5, looking at the assembled state of the present invention, as shown in Figure 5 when tightening the elastic cell locking nut 10 in the direction of the arrow, the locking step 17 of the body 12 Integral washer 40 is caught is pressed.

그리고, 계속하여 압력을 가하여 셀프록킹너트(10)를 볼트(30)에 조여주게 되면 가압물(50)을 고정시킴과 동시에, 일체형와셔(20)가 연질링(24)을 누르게 되고, 그 눌림작용으로 연질링(24)이 내측으로 이동하면서 볼트(30)의 외측 나사산을 가압하여 눌러주므로 셀프록킹너트(10)가 볼트(30)에서 이탈되는 것을 방지한다.When the self-locking nut 10 is tightened to the bolt 30 by applying pressure continuously, the pressurized product 50 is fixed, and the integral washer 20 presses the soft ring 24. By acting as the soft ring 24 moves inward, the outer thread of the bolt 30 is pressed and pressed to prevent the self-locking nut 10 from being separated from the bolt 30.

한편, 본 발명에 따른 셀프록킹너트(10)를 볼트(30)에서 조립을 해제한 후에 재차 탄성셀프록킹너트(10)를 볼트(30)에 조립하더라도 이미 연질링(24)에 나사산이 형성되어 결합력이 약화됨에도 불구하고, 조립 압력에 의하여 일체형와셔(20)가 연결링(24)을 가압하여 눌러주게 된다.Meanwhile, even after the self-locking nut 10 according to the present invention is released from the bolt 30, the thread is formed in the soft ring 24 even though the elastic self-locking nut 10 is assembled to the bolt 30 again. Despite the weakening of the coupling force, the integral washer 20 presses the connection ring 24 by the assembly pressure.

즉, 분해, 조립이 반복되어서 연질링(24)에 나사산이 형성되더라도 셀프록킹너트(10)를 조여주기만 하면, 일체형 와셔(20)가 연질링(24)을 가압하여 볼트(30)의 외주면으로 눌러주므로 셀프록킹너트(10)를 반복하여 사용하더라도 셀프록킹너트(10)의 체결력이 약화되어지 않게 된다.That is, even if the thread is formed in the soft ring 24 by disassembling and assembling repeatedly, the integral washer 20 presses the soft ring 24 to the outer circumferential surface of the bolt 30 by simply tightening the self-locking nut 10. Since the self-locking nut 10 is repeatedly used, the clamping force of the self-locking nut 10 is not weakened.

상기한 바와 같이, 본 발명에 따른 탄성 셀프 록킹너트를 이용하게 되면, 셀프 록킹너트가 가압물에 접촉되는 부분에 요홈부를 갖는 걸림턱을 형성하고, 이 걸림턱내에 걸림요홈이 걸려지도록 일체형와셔를 설치하여 너트를 조일 때, 일체형 와셔가 연결링을 가압하여 연질링이 볼트의 외측면을 강하게 가압하여 고정시키므로 반복하여 너트를 사용하더라도 체결력이 약화되는 것을 방지하도록 하는 매우 유용하고 효과적인 발명이다.As described above, when the elastic self-locking nut according to the present invention is used, a locking jaw having a recess is formed in a portion where the self-locking nut is in contact with the pressurized water, and the integral washer is fitted to catch the locking recess in the locking jaw. When installing and tightening the nut, the one-piece washer presses the connection ring so that the soft ring strongly presses and fixes the outer surface of the bolt, so that the fastening force is prevented from being weakened even when the nut is repeatedly used.
