본 고안은 전선의 설치 작업시 외부로부터 가해지는 충격이나 또는 높은 압력하에서도 전선을 안전하게 보호하기 위한 전선 보호관용 덕트(電線保護管用 Duct=일명 자바라=)에 관한 것이다.The present invention relates to a duct for electric wire protection tube (aka bellows) for protecting the electric wire even under high pressure or impact from the outside during the installation of the electric wire.
상세하게는 스텐레스나 주철 및 아연도금 강판등을 주재로 하여 띠모양으로 폭을 일정하게 길이방향으로 절단시킨 성형부재를 압압로울러에 의해 그 단면이자형으로 이루워지도록 성형한 2가닥의 성형부재가 서로 그 연부로 절곡된자형의 걸림부와자형의 걸림부로 맞걸려서 덕트로 구성되어지기 위해 상기 2가닥의 성형부재를 각각형 형태와자형 걸림부로 맞걸려서 덕트로 구성되어지기 위해 상기 2가닥의 성형부재를 각각형 형태와자형태로 위치시켜 2가닥의 이들 성형부재를 동시에 나선상으로 권회시키면자형의 걸림부와자형의 걸림부가 동일한 구성에 따른 반복 권취작업에 의해 순차적으로 걸리면서 나선상의 전선보호관용 덕트를 제공하게 되는 것이다.In detail, the cross-section of the formed member cut in the longitudinal direction in the form of a band, mainly made of stainless steel, cast iron, and galvanized steel sheet, is pressed by a roller. Two-shaped molded members molded to form a female shape are bent to each other at their edges. Shaped hangers The two strands of molding members are respectively formed to be composed of a duct by engaging with a locking part of a shape. Mold mode and The two strands of the molded member are respectively formed to be composed of a duct by engaging with a female locking portion. Mold mode and When placed in the shape of a child and wound two strands of these molded members at the same time spirally Shaped hangers The locking part of the female is sequentially caught by the repeated winding operation according to the same configuration is to provide a spiral wire protection tube duct.
이와같이 구성된 본 고안의 덕트는 사용시 어떠한 방향으로 꾸부리더라도 2가닥의자형과자형의 성형부재에 의한자형 걸림부와자형 걸림부로 걸려진 연결부는 그 휘임각도가 커서 꾸부려지는 각도가 심하더라도 종래와 같이 연결부가 터지거나 틈새가 생겨 전선이 노출되는 결점을 제거할 수 있는 견고한 덕트를 제공하는데 그 목적이 있고 본 고안의 또 다른 목적은자형으로 압압하여 구성한 2가닥의 성형부재를 사용하여 동시에 나선상으로 권회시키므로서 덕트의 신장작용과 신축작용을 크게 할 수 있다.The duct of the present invention configured as described above has two strands, regardless of the direction Shape By shaped molding member Shaped hangers Although the connection part caught by the shape-hanging part has a large bending angle, and the decoration angle is severe, the purpose of the present invention is to provide a rigid duct that can remove the defect that the connection part is exposed due to the connection part bursting or gap as in the prior art. Another purpose of It is possible to increase the stretching and stretching of the duct by simultaneously winding spirally using two strands of the molded member formed by pressing in the shape of a child.
종래의 전선 보호관용 덕트는 첨부된 도면 제 1 도의 (a)(b)도에서 보는 바와 같이 띠모양으로된 성형부재(1)의 양측연부를 서로 반대방향으로 "L"자형과 "ㄱ"자형으로 절곡시킨 걸림부(2)(2')와 또 "ㄷ"자형과자형으로 절곡시킨 걸림부(3)(3')로 이루어진 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 have a "L" shape and an "a" shape in opposite directions to both edges of the band-shaped forming member 1 as shown in (a) and (b) of FIG. Hooking portion (2) (2 ') bent with a When the wires are wound in a spiral shape by the locking parts 3 and 3 'which are bent in a shape, the locking parts 2, 2', 3 and 3 'are engaged with each other for a wire protection tube in a desired state. The ducts 4 and 4 'are constituted.
그런데 상기 (a)도에 도시한 덕트(4)의 경우는, "ㄴ"자형의 걸림부(2)와 "ㄱ"자형의 걸림부(2')와 수직상태 맞물려 걸려 있기 때문에 꾸부리는 각도를 크게 할때는 상기 연결부(A)가 벗겨져서 그 내부의 전선이 노출되는 결합이 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.By the way, in the case of the duct 4 shown in the above (a), the angle to be decorated is fixed because it is engaged with the "b" shaped locking portion 2 and the "b" shaped locking portion 2 ' When it is enlarged, the connection part A is peeled off, and there is a bond in which the wires inside are exposed, and when the work for extending the length is performed, there is no problem in the stretching action, but the connection part A is caught when the stretching force is strong in the stretching action. There was a defect that part (2) (2 ') was peeled off.
그리고 (b)도에 도시한 덕트(4')의 고리모양으로 "ㄷ"자형과자혀으로 꼬부려진 상태로 맞물려 있어서 덕트(4')를 꾸부릴때 연결부(A')가 벌어지는 일은 극소하지만 상기 걸림부(3)(3')가 맞물려 있는 폭(ℓ)만큼 덕트(4')를 꾸부릴때 그 각도가 크지 못한 폐단이 있고 특히 신작용에 따른 신축거리와 신장거리가 연결부(A')의 걸림부(3)(3')로 인한 폭(ℓ)만큼 단축되는 결함이 있을 뿐만 아니라 상기 덕트(4)에 비해 재료의 소모가 더 크고 작업도 복잡한 등의 원가를 상승시키는 문제점이 있다.And (b) a ring of duct 4 'as shown in FIG. Although the connection portion A 'is very small when the duct 4' is engaged in a state of being twisted with a pinch, the duct 4 'is as wide as the engaging width L of the engaging portions 3 and 3'. There is a defect that the angle is not large when decorating, especially the stretching distance and extension distance according to the new action is shortened by the width (ℓ) due to the engaging portion (3) (3 ') of the connection (A'). In addition, 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 이와 같은 결점을 시정하기 위해 안출한 것으로서자형으로 성형된 2가닥의 성형부재에 의해서 그 양측연부가 서로 반대방향으로자형과자형으로 절곡된 걸림부로 걸려지도록 상기 성형부재의 위치를 서로자형태와자형태로 하여서된 2가닥의 성형부재를 동시에 사용하여 덕트를 성형하므로서 연결부를 견고히 함과 동시에 신장작용은 물론 신축작용과 더불어 꾸부림 각도를 크게할 수 있는 것을 특징으로한 것이다.Therefore, the present invention was devised to correct such defects. The two edges are formed in the shape of two strands in opposite directions to each other. Shape The position of the molding member to be hooked to each other so as to be caught by the engaging portion bent in a shape Shape and By forming the duct by using the two-shaped molding member in the shape of a child at the same time, it is characterized in that it is possible to increase the angle of decoration as well as the stretching action as well as the stretching action.
본 고안을 첨부한 도면 제 2 도와 제 3 도를 참고로 하여 설명한다.The present invention will be described with reference to FIGS. 2 and 3 of the accompanying drawings.
본 고안의 제 2 도는 띠 모양으로 형성된 2가닥의 성형부재(1a)(1a')양측연부로 절곡된자형의 걸림부(2a)와자형의 걸(2a')가 서로 걸려지도록 단면이자형으로된 성형부재(1a)(1a')위치를 서로자형태와,자형태로 하여 이들 2가닥의 성형부재(1a)(1a')를 동시에 나선상으로 권회시키는 덕트(4a)의 실시예를 나타낸 사시도로서자형 성형부재(1a)의자형 성형부재(1a)와자형 성형부재(1a')를 동시에 나선상으로 반복권회시켜서 걸림부(2a)와 걸림부(2a')가자형으로 걸리는 연결부(a)에 의해서 덕트(4a)를 구성한 것으로서 그 작용효과는 본문 명세서의 서두에서도 약간 언급되어 있는 바와 같이 덕트(4a)의 꾸부림 각도를 크게 하더라도 2가닥의 구성된자형과자형의 성형부재(1a)(1a')로 인해 그 림부(2a)(2a')가 서로자형상의 연결부(a)에서 같이 경사각을 이룬 상태로 맞물려 있기 때문에 상기 연결부(a)가 종래와 같이 덕트(4a)의 각도를 심하게 꾸부리더라도 벌어지는 일이 없을 뿐만 아니라 신장 및 신축작용에 있어서도 그 길이를 크게 조절할 수 있는 이점이 있고 또한 작업이 간단하여 다량생산에 임할 수 있는 원가절감의 효과도 겸한다.2 of the present invention is bent in both ends of the two-shaped molded member (1a) (1a ') formed in a band shape And the shaped locking part 2a Cross-section so that the hooks (2a ') Positioning the shaped members 1a and 1a 'shaped to each other Shape, As a perspective view showing an embodiment of a duct 4a in which the two strand forming members 1a and 1a 'are simultaneously wound spirally in a shape of a child. Of the shaped member 1a And the female molding member 1a By simultaneously winding the female molding member 1a 'repeatedly in a spiral form, the locking portion 2a and the locking portion 2a' The duct 4a is formed by the connecting part a, which is shaped like a child, and its effect is that even if the angle of the duct 4a is increased as mentioned at the beginning of the specification, it is composed of two strands. Shape Due to the shaped members 1a and 1a ', the drawing portions 2a and 2a' Since the connection part (a) is engaged in the form of an inclination angle as in the shape of the connection part (a), the connection part (a) does not open even if the angle of the duct 4a is severely decorated as in the prior art, and its length also in stretching and stretching action. It has the advantage of large control, and the simple operation also reduces the cost for mass production.
