본 고안은 전선의 설치 작업시 외부로부터 가해지는 충격과 또는 높은 압력하에서도 안전하게 보호하기 위한 전선 보호관용 덕트(電線保護管用 Duct=일명자바라=蛇腹)에 관한 것이다.The present invention relates to a duct for electric wire protection tube (aka Zabara = 안전하게) for safe protection even from the impact from the outside during the installation of the wire or under high pressure.

상세하게는 스텐레스나 주철 및 아연 도금 강판등을 주재로 하여 띠모양으로 폭이 일정하게 길이 방향으로 절단한 성형부재를 압압로울러에 의해 단면이 ""자형으로 이루워지도록 성형하여 나선상으로 권회작업을 실시하면 상기 띠모양으로된 성형부재의 일측연부로 절곡된 ""자형 걸림부와 상기 성형부재의 반대쪽 연부로 절곡된 ""자형의 걸림부가 서로 동일한 구성의 반복작업에 의해 순차적으로 걸리면서 나선상의 전선 보호관용 덕트를 형성하게 되는 것이다.In detail, the cross-sectional shape of the formed member cut in the longitudinal direction with the width of the strip in the form of a band mainly made of stainless steel, cast iron, and galvanized steel sheet is " "Molded to form a magnetic shape and spirally wound to be bent to one side edge of the band-shaped forming member" "Bent to the opposite edge of the shaped engaging portion and said forming member" "The locking part of the shape is sequentially caught by the repetitive work of the same configuration to form a spiral wire protection tube duct.

이와같은 본 고안은 성형된 덕트를 어떠한 방향으로 꾸부리더라도 ""자형 걸림부와 ""자형 걸림부에 의해 걸린 연결부의 휘임 각도가 커서 꾸부려지는 각도가 심해도 연결부가 터지거나 틈새가 생겨 전선이 노출되는 경우를 방지하는데 그 목적이 있고 본 고안의 또 다른 목적은 성형부재를 ""자형으로 압압 구성하여 나선상으로 연결하므로서 덕트의 신장작용을 그만큼 크게할 수 있도록 하는데 있다.The present invention can be used to decorate the molded duct in any direction. "With a hanger" "Even if the bending angle of the connecting part caught by the shaped locking part is large and the angle to be decorated is severe, the purpose is to prevent the connection part from bursting or gaps and exposing the wire. "Compression configuration in the shape of a spiral connected to the spiral so as to increase the expansion of the duct.

종래의 전선 보호관용 덕트는 첨부된 도면 제1a도, 제1b도에서 보는 바와 같이 띠모양으로된 성형부재(1)의 양측 연부를 서로 반대방향으로 "ㄴ"자형과 "ㄱ"자형으로 절곡시킨 걸림부(2), (2')와 또 ""자형과 ""자형으로 절곡시킨 걸림부(3), (3')로 이루워진 것에 의해서 나선상으로 권회시킬 때 상기 걸림부(2), (2'), (3), (3')는 서로 맞걸려 소망하는 상태의 전선 보호관용 덕트(4), (4')를 구성하게 된다.Conventional wire protective tube ducts are formed by bending both edges of the band-shaped forming member 1 in the opposite directions as shown in FIGS. 1A and 1B. 2, 2 'and " "Shaped and" "When the windings are spirally formed by the locking parts 3 and 3 'bent in a shape, the locking parts 2, 2', 3 and 3 'are desired to be engaged with each other. The electric wire protection pipe ducts 4 and 4 'of the state to be made are comprised.

그런데 상기 제1a도에 도시한 덕트(4)의 경우는 "ㄴ"자형의 걸림부(2)와 "ㄱ"자형의 걸림부(2')가 수직 상태로 맞물려 걸려 있기 때문에 꾸부리는 각도를 크게 할때는 상기 연결부(A)가 벗겨져서 그 내부의 전선이 노출되는 결함이 있었고 또한 그 길이를 신장시키기 위한 작업을 행할때도 신축작용에는 별지장이 없으나 신장작용에서 신장력을 강하게 할때는 상기 연결부(A)의 걸림부(2), (2')가 벗겨지는 결점이 있었다.However, in the case of the duct 4 shown in FIG. When the connection part (A) is peeled off and there is a defect that the wire inside thereof is exposed and there is no problem in the stretching action even when working to extend the length, but when the strengthening force in the stretching action when the engaging portion of the connection part (A) (2), (2 ') had a flaw that came off.

그리고 제1b도에 도시한 덕트(4')의 경우는 (a)도의 것보다 견고하고 제품의 질도 양호하지만 이 또한 다음과 같은 미비점을 수반하고 있다.In the case of the duct 4 'shown in FIG.

즉, 양쪽연부의 걸림부(3), (3')가 고리모양으로 ""자형과 ""자형으로 꼬부려진 상태로 맞물려 있어서 덕트(4')를 꾸부릴 때 연결부(A')가 벌어지는 일은 극소하지만 상기 걸림부(3), (3')가 맞물려 있는 폭(ℓ)만큼 덕트(4')를 꾸부릴 때 그 각도가 크지못한 폐단이 있고 특히 신장작용에 따른 신축거리와 신장거리가 연결부(A')의 걸림부(3), (3')로 인한 폭(ℓ)만큼 단축되는 결함이 있을뿐만 아니라 상기 덕트(4)에 비해 재료의 소모가 더 크고 작업도 복잡한 등의 원가를 상승시키는 문제점이 있었다.In other words, the engaging portions 3, 3 'at both edges have a ring shape. "Shaped and" &Quot; The connection A 'is very small when the duct 4' is engaged in a twisted state, but the duct 4 is as wide as the width L in which the engaging portions 3 and 3 'are engaged. ') Has a closed end with a small angle, especially the stretch and stretch distances due to the stretching action is shortened by the width (ℓ) due to the engaging portions (3), (3') of the connection (A ') In addition to the defects, there is a problem in that the cost of the material is higher than that of the duct 4 and the work is complicated.

따라서 본 고안에서는 이와같은 결점을 시정하기 위해 안출한 것으로 띠모양으로 성형된 성형부재의 양측연부가 서로 반대방향으로 ""자형과 ""자형으로 절곡되는 걸림부에 의해 덕트가 형성되도록 상기 성형부재를 ""자형으로 구성하므로서 연결부를 견고히함과 동시에 신장작용과 꾸부림 각도를 크게할 수 있는 것을 특징으로한 것이다.Therefore, in the present invention, both side edges of the strip-shaped molded members formed in order to correct such defects are in opposite directions. "Shaped and" "The forming member is formed so that the duct is formed by the engaging portion that is bent in a" "It is characterized by being able to increase the elongation action and the degree of decoration, while at the same time solidifying the connection portion.

본 고안을 첨부한 도면 제2도와 제3도를 참고로 하여 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to FIGS. 2 and 3 of the accompanying drawings.

본 고안의 제2도는 띠모양으로 형성된 성형부재(1a)의 양측연부를 ""자형의 걸림부(2a)와 ""자형의 걸림부(2a')가 서로 반대방향으로 이루워지도록 상기 성형부재(1a)의 단면을 ""자형으로 압압하여 나선상으로 권회시키는 덕트(4a)의 실시예를 나타낸 사시도로서 ""자형 걸림부(2a)에 다시 반대쪽의 ""자형 걸림부(2a')가 순차적으로 걸려 반복 권회되면서 걸림부(2a)와 걸림부(2a')가 본 고안 제3도에서와 보는 바와 같이 ""자형으로 걸리는 연결부(a)에 의해서 구성되는 것으로서 그 작용 효과는 본문 명세서의 서두에서도 약간 언급되어 있는바와 같이 덕트(4a)의 꾸부림 각도를 크게 하더라도 걸림부(2a), (2a')가 서로 ""자형상의 연결부(a)에서 같이 경사각을 이룬 상태로 맞물려 있기 때문에 상기 연결부(a)가 종래와 같이 덕트(4a)의 각도를 심하게 꾸부리더라도 벌어지는 일이 없을뿐만 아니라 신장 작용에 있어서도 그 길이를 크게 조절할 수 있는 이점이 있고 또한 작업이 간단하여 다량 생산에 임할 수 있는 원가절감의 효과도 겸하는 이점이 있다.FIG. 2 of the present invention shows that both side edges of the molding member 1a formed in a band shape are " &Quot; shaped locking portion 2a " "The cross section of the said shaping | molding member 1a is made so that a female locking part 2a 'may be made to oppose each other." "A perspective view showing an embodiment of a duct 4a which is pressed in a shape and wound in a spiral shape" On the opposite side again to the " "As the engaging portion 2a 'is sequentially caught and repeatedly wound, the engaging portion 2a and the engaging portion 2a' are as shown in FIG. "It is composed of a connecting part (a) hanging in the shape, the effect of the operation is mentioned slightly at the beginning of the text specification, even if the angle of the duct (4a) is increased, the locking parts (2a), (2a ') each other " "Because the connection part (a) is engaged in the form of an inclination angle as in the shape of the connection part (a), even if the connection part (a) is severely inclined at an angle of the duct (4a) as in the prior art, it does not open and extends its length even in the stretching action. There is an advantage that can be largely adjusted, and also has the advantage of the cost saving effect that can be applied to mass production because the operation is simple.
