Abstract

The present invention relates to an anti-loosening bolt member using a heat-shrinkable tube, and more particularly, to an anti-loosening bolt member using a heat-shrinkable tube that can prevent loosening of a bolt member when the bolt member is fastened and a hardener capsule is hardened by bursting. In manufacturing the anti-loosening bolt member, a heat-shrinkable tube is heated and coated on the outer periphery of a screw thread of the bolt member having a screw thread. In such a heat-shrinkable tube, the hardener capsule is included. In addition, this process is carried out in steps such as packaging or inspection when manufacturing the bolt member, so that there is no need to add a separate process, thereby capable of simplifying the process and management compared to a prior art, and also reducing a manufacturing cost.

Description

열수축 튜브를 활용한 풀림 방지 볼트부재{Loosen-proof bolt member using heat shrink tube}Loosen-proof bolt member using heat shrink tube}

본 발명은 경화제 캡슐이 포함된 열수축 튜브를, 볼트부재의 나사산 부분에 코팅하여 사용함으로써, 볼트부재가 체결시 경화제 캡슐이 터지면서 풀림이 방지될 수 있도록 하는 열수축 튜브를 활용한 풀림 방지 볼트부재에 관한 것이다.The present invention uses a heat-shrinkable tube containing a curing agent capsule to be coated on the threaded portion of the bolt member, thereby preventing loosening by using a heat-shrinkable tube to prevent loosening while the curing agent capsule bursts when the bolt member is fastened. it's about

일반적으로 볼트는 너트와 더불어 두 개의 구조체를 결합시키거나, 구조체 자체에 형성된 나사산으로 이루어진 체결공에 다른 결합체를 관통하여 체결하는 체결구로써 사용이 된다. 상기한 바와 같은 볼트는 체결용으로는 싱글 너트만으로 제품을 고정하는 경우가 대부분이며 확실한 고정이 필요하다고 느끼는 곳에는 두 개의 너트를 사용하는 더블너트 또는, 풀림 방지용 너트를 사용하게 된다.In general, a bolt is used as a fastener for coupling two structures together with a nut or for fastening through another coupling body to a fastening hole made of a thread formed in the structure itself. In most cases, the bolts as described above are fixed with only a single nut for fastening, and a double nut using two nuts or a nut for preventing loosening is used where a reliable fixation is felt.

상기한 바와 같은 볼트를 수용하게 되는 풀림방지너트를 이용한 기술이 개시 되어 있지만, 너트를 필요로 하지 않는 구조체의 모재 자체에 형성된 체결공에 볼트를 체결하는 형태의 곳에는 진동, 충격 등으로 인하여 체결당시의 조임상태를 유지하지 못하고 볼트의 미끄럼 현상이 발생되어 풀림이 진행된다.Although the technology using the anti-loosening nut that accommodates the bolt as described above has been disclosed, it is fastened due to vibration, shock, etc. in the place where the bolt is fastened to the fastening hole formed in the base material itself of the structure that does not require a nut. The tightening state at the time cannot be maintained, and the bolt slips and loosens.

특히, 볼트 본체에 스프링을 결착하는 탭을 수용하고 그 탭에 코일스프링을 수용하여 코일스프링의 조임력을 이용하여 풀림방지하는 볼트가 선행되어 왔다.In particular, a bolt that accommodates a tab for binding a spring to a bolt body and accommodates a coil spring in the tab to prevent loosening by using the tightening force of the coil spring has been preceded.

그러나, 상기 이러한 종래의 경우에도, 진동이 지속적으로 발생하는 철도의 주요부분, 교량의 연결부분, 바람의 흔들림이 많은 철탑, 흔들림이 많은 놀이기구 등등 인명에 가장 민감한 곳에서는 풀림 방지용 볼트의 중요성은 절대적이나, 그 풀림이 임의로 해제되어 안전사고가 종종 발생한다는 문제점이 있고, 또한, 보수나 점검을 위해 필요한 경우에는 너트를 풀고 다시 조여야 하는데 사용과 작업이 어려운 문제점이 있었다.However, even in this conventional case, the importance of the bolt for preventing loosening is the most sensitive to human life, such as the main part of the railway where the vibration is continuously generated, the connection part of the bridge, the pylon with a lot of wind, and the play equipment with a lot of shaking. Although absolute, there is a problem that safety accidents often occur because the loosening is arbitrarily released. Also, when it is necessary for maintenance or inspection, the nut must be loosened and tightened again, which is difficult to use and work.

더불어, 상기와 같은 선행기술뿐만 아니라, 스크류의 풀림방지를 위해 나사산에 돌기를 만들고, 볼트 좌면에 세레이션 가공을 사용하는 방식이 사용되거나, 별도의 경화제를 사용하여 풀림을 방지하는 방식이 사용되기도 하였다.In addition, in addition to the prior art as described above, a method of making a protrusion on the thread to prevent loosening of the screw and using a serration processing on the bolt seat surface is used, or a method of preventing loosening by using a separate hardener is used. did.

하지만, 전자는 체결대상물의 파손 및 풀림토크 저하가 발생하였고, 후자는 공정증가 및 비용상승뿐만 아니라, 장기보관시 열화되는 문제도 있다.However, in the former case, damage to the fastening object and a decrease in loosening torque occurred, and in the latter, there is a problem that not only increases the process and increases the cost, but also deteriorates during long-term storage.

이에, 이러한 문제를 해결할 수 있는 풀림방지용 볼트부재의 개발이 절실히 대두되고 있는 실정이다.Accordingly, there is an urgent need to develop a bolt member for preventing loosening that can solve this problem.
