또한 본 고안에 따른 상기 고정구 몸체(77)는 사출성형하여 일체로 성형하였다.In addition, the fixture body 77 according to the present invention was molded by injection molding integrally.
이상에서와 같은 본 고안의 실시예에 의한 클럭스크링의 작용·효과를 설명한다.The operation and effects of the clock screen according to the embodiment of the present invention as described above will be described.
클럭스프링(64)의 내·외측링(60)(61)을 셋팅하고자 하는 회전위치에 놓은 다음 고정구몸체(77)에 형성된 외측링협지부(73)를 상기 외측링(61)에 형성된 체결용 플랜지(62)에 횡으로 끼워 물린 다음 고정구몸체(77)의 중앙과 끝단에 형성된 탄성협지부(71)와 내측링협지부(72)를 내측링(60)의 단면에서 돌설된 위치결정돌기(66)와 각형돌기(67)에 강제로 밀어넣게 되면, 탄성협지부(71)는 탄성변형되면서 확개되어 위치결정돌기(66)의 턱(65)에 걸리게 되어 고정구몸체(77)의 끼움방향이탈을 방지하게 되며, 내측링협지부(72)는 각형돌기(67)와 결합되어 고정구 몸체(77)가 자회전하는 것을 방지하게 된다.Fastening flange formed on the outer ring 61 by placing the inner and outer rings 60 and 61 of the clock spring 64 in the rotational position to be set and then the outer ring clamping portion 73 formed on the fixture body 77. Positioning projections 66 protruding from the cross section of the inner ring 60, the elastic clamping portion 71 and the inner ring clamping portion 72 formed at the center and the end of the fastener body 77 after being intersected with (62). When the force is pushed into the square projection 67, the elastic clamping portion 71 is expanded and elastically deformed and caught by the jaw 65 of the positioning projection 66 to prevent the fitting body 77 from deviating from the fitting direction. The inner ring clamp 72 is coupled with the square projection 67 to prevent the fixture body 77 from rotating in itself.
상기와 같은 상태에서 클럭스프링(64)은 고정구몸체(77)에 의해 내·외측링(60)(61)의 한 몸체인 상태가 되어 회전이 방지된 상태이다.In the above state, the clock spring 64 is in a state of being one body of the inner and outer rings 60 and 61 by the fixture body 77, thereby preventing rotation.
이 상태에서 상기 클럭스프링(64)의 내·외측링(60)(61)을 고정체와 회전체 예컨대, 자동차의 휠하우징과 휠측에 고정설치하고 난 다음에 상기 고정구몸체(77)를 클럭스프링(64)으로부터 탈거하여 제거시키려 할 경우에는 고정구몸체(77)에 형성된 손잡이(70)를 손으로 강하게 잡게 되면, 탄성협지부(71)가 확개되어 위치결정돌기(66)의 턱(65)으로부터 아무런 저항을 받지 않게 되므로 이 상태에서 고정구몸체(77)를 잡아당겨서 이탈시키면 된다.In this state, the inner and outer rings 60 and 61 of the clock spring 64 are fixed to a stationary body and a rotating body, for example, a wheel housing and a wheel side of an automobile, and then the fixture body 77 is clocked. In the case of removing and removing from 64, when the handle 70 formed on the fastener body 77 is firmly gripped by hand, the elastic clamping portion 71 is enlarged and the jaw 65 of the positioning protrusion 66 is removed. Since no resistance is received, it is enough to pull out the fixture body 77 in this state.
이상에서와 같이 본 고안은 기존과 같이 접착테이프로 클럭스프링을 임시 고정할 때와 같이 테이프의 늘어짐에 의한 셋팅위치결정의 어긋남이 발생하지 않게 되며, 손잡이를 선으로 잡고 밀어 넣거나 잡아당기는 간단한 조작만으로도 클럭스프링의 내·외측링을 고정할 수 있으므로 사용에 매우 편리하며, 생산라인에서의 생산성 향상을 기할 수 있는 것이다.As described above, the present invention does not cause misalignment of the setting positioning due to the sagging of the tape as in the case of temporarily fixing the clock spring with the adhesive tape as in the past. Since the inner and outer rings of the clock spring can be fixed, it is very convenient to use and productivity can be improved in the production line.
