첨부도면 [도 2] 및 [도 3a][도 3b]는 본 고안에 따른 구체적인 실시예, 즉, 체결볼트풀림방지(10)를 보인 예시도이다.2 and 3 is an exemplary view showing a specific embodiment according to the present invention, that is, fastening bolt loosening prevention (10).
피체결부재(15)(16)에 메인볼트(11)를 나사결합시켜 이들을 결속시키도록 하되 메인볼트(11)외에 큰 평와샤(14)와, 나사공(12-1)에 잭볼트(13)가 나사 결합 되어지는 보조결속체(12)를 구비한다.The main bolts 11 are screwed to the fastened members 15 and 16 so as to bind them, but the large flat washer 14 and the screw bolts 12-1 and the jack bolts 13 are provided in addition to the main bolts 11. ) Is provided with an auxiliary binder 12 to be screwed together.
상기 보조결속체(12)는 결속력의 정도에 따라 그 모양을 달리할 수 있는데 예컨대 [도 3a]에 도시된 바와 같이 강한 결속력(실질적으로는 외측으로 작용하는힘)이 필요로 하는 경우에는 원형으로된 보조결속체(12)를 사용하고 다소적은 결속력이 요구되는 경우에는 [도 3b]에 도시된 바와 같이 장방형으로 된 보조결속체(12)를 사용한다.The auxiliary binding body 12 may vary in shape depending on the degree of binding force, for example, as shown in FIG. 3A, in the case of requiring a strong binding force (actually acting outwardly) as a circular shape. If the secondary binder 12 is used, and a small amount of binding force is required, the secondary binder 12 having a rectangular shape is used as shown in FIG. 3B.
메인볼트(11)와 잭볼트(13)를 나사결합시킬 때 통상의 스프링와샤(2) 또는 평와샤(2)를 와샤(18)로 사용하여도 무방한다.When the main bolt 11 and the jack bolt 13 are screwed together, an ordinary spring washer 2 or flat washer 2 may be used as the washer 18.
이하 결합구조 및 작동관계를 설명한다.Hereinafter, the coupling structure and the operation relationship will be described.
나사공(12-1)에 잭볼트(13)를 나사결합시키되 와사(18)를 개입시켜 결속력을 강화시켜주도록 한다.Screw the bolt (13) to the screw hole (12-1) through the washer (18) to strengthen the binding force.
메인볼트(11)에 와샤(17)를 개입시켜 보조결속체(12)에 삽입하거나 나사결합시키고 다시 큰평와샤(14)를 끼운후 피체결부재(15)(16)에 나사결합 시킨다.The main bolt 11 is inserted into the auxiliary fastener 12 or screwed through the washer 17 through the main bolt 11, and then the large flat washer 14 is inserted and screwed to the fastened member 15 and 16.
메인볼트(11)를 완전히 결속시키기 전에 잭볼트(13)를 나사결합시켜 그 선단이 보조결속체(12)의 하측으로 노출될 수 있도록 조정시킨 상태에서 메인볼트(11)를 완전히 결속시켜주며, 잭볼트(13)는 적절하게 조정하면서 결속(나사결합)시켜주되 이때에는 메인볼트(11)도 재차 나사결합시켜주면 체결은 완료된다.Before the main bolt 11 is completely engaged, the main bolt 11 is completely engaged in a state in which the tip of the jack bolt 13 is screwed so that the front end thereof is exposed to the lower side of the auxiliary binder 12. While the jack bolts 13 are properly adjusted, they are bound (screwed together). At this time, the main bolts 11 are also screwed again to complete the fastening.
이와 같이하여 결속되어진 체결볼트풀림방지장치(10)는 메인볼트(11)의 체결력에 의해 보조결속체(12)를 포함한 피체결부재(15)가 결속되어지고 잭볼트(13)의 체결력은 큰평와샤(14)를 하측으로 밀어 피체결부재(15)의 체결력에 부가되어지고 또한 메인볼트(11)에 의해 하측으로 작용되는 체결력의 반대 방향인 상측으로 반발인장력이 작용하게 되며, 따라서 피체결부재(15)(16)와 메인볼트(11)에는 메인볼트(11)의 체결력(F)외에 잭볼트(13)의 체결력(T)이 이중으로 부가되어지게 되므로 체결력은 매우 증대되어 지는 것이다.In this way, the fastening bolt loosening prevention device 10, which is bound in this way, is to be fastened by the fastening force of the main bolt 11, and the fastening member 15 including the auxiliary fastening body 12 is fastened, and the fastening force of the jack bolt 13 is large flat. Push the washer 14 downward to add to the fastening force of the member 15 to be fastened, and the repulsion tension force acts upward, which is the opposite direction of the fastening force acting downward by the main bolt 11, and thus the member to be fastened. In addition to the fastening force (F) of the main bolt 11, the fastening force (T) of the jack bolt 13 is added to the (15) (16) and the main bolt (11) is a fastening force is very increased.
이와 같이 본 고안은 지름이 큰 볼트를 체결시킬 때 메인볼트에 무리한 힘을 가하지 않더라도 보조볼트들의 체결력이 가미되어져 결속력이 크게 강화되고 메인볼트의 체결 및 해제를 용이하게 실시할 수 있으며, 피체결부재(15)에 진동이 전이되더라도 진동력이 큰평와샤(14)와 보조결속체(12)의 사이에서 대부분 소멸되어버리므로 메인볼트(11)의 체결력에는 아무런 영향을 미치지 않게 되고 따라서 체결상태는 인위적으로 풀어 분리시키지 않는한 해제되어 지지 않게 되는 것이다.As such, the present invention does not exert excessive force on the main bolt when tightening the large diameter bolt, so that the tightening force of the auxiliary bolts is added, thereby greatly strengthening the binding force, and easily tightening and releasing the main bolt. Even if the vibration is transferred to (15), since the vibration force is largely dissipated between the large flat washer 14 and the auxiliary binding member 12, there is no influence on the fastening force of the main bolt 11, and thus the fastening state is artificial. It will not be released unless it is released.
이상에서와 같이 본 고안에 따르면, 메인볼트(11)의 결속력에 보조결속체(12)에 나사결합된 잭볼트(13)의 결속력이 배가 되어지므로 결속력이 크게 강하되어짐에도 불구하고 메인볼트(11)는 작은 힘으로도 능히 결속해제시킬 수 있어 결속시간이 단축되어질 뿐만 아니라 용이하게 결속해제 시킬 수 있어 결속시간이 단축되어질 뿐만 아니라 용이하게 결속 해제 시킬 수 있게 되며 진동이 발생되더라도 보조결속체(12)와 큰평와샤(14) 사이에서 소진되어져 버려 메인볼트(11)를 포함한 결속력은 원상태를 지속적으로 유지시키게 된다는 것이다.As described above, according to the present invention, the binding force of the jack bolt 13 screwed to the auxiliary binding member 12 is doubled to the binding force of the main bolt 11, even though the binding force is greatly reduced, the main bolt 11 ) Can be easily disengaged with a small force, which not only shortens the binding time but also makes it easier to disengage, thereby shortening the binding time and making it easier to disengage, even if vibration occurs. ) And exhaustion between the large flat washer 14, the binding force including the main bolt 11 is to maintain the original state continuously.
