십자몸체(11)의 상단에 일정간격으로 고정봉(13)이 돌출 형성되고, 고정봉(13)의 단부 외경에 나사산이 형성되어 후술할 행거봉(1)과 커플러(40)로 고정된다.The fixing rod 13 is protruded at a predetermined interval on the upper end of the cross body 11, a screw thread is formed in the outer diameter of the end of the fixing rod 13 is fixed to the hanger rod 1 and the coupler 40 to be described later.

십자몸체(11)는 전자파가 통과하지 못하도록 내부에 도전체로 내심이 존재하고, 외부는 플라스틱으로 성형하여 형성하는 것이 바람직하다.The cross body 11 has an inner core as a conductor to prevent electromagnetic waves from passing through, and the outer body 11 is preferably molded by plastic.

덮개판체(20)는 십자몸체(11)에서 네방향으로 각각 돌출된 길이만큼의 폭을 가지도록 네쌍의 장방형 판체(21)가 형성되고, 각각의 판체(21) 일측단에 힌지부(22)가 각각 형성된다.The cover plate body 20 has four pairs of rectangular plate bodies 21 formed to have widths corresponding to the lengths protruding in four directions from the cross body 11, and hinge portions 22 are formed at one end of each plate body 21. Are each formed.

판체(21)는 덕트본체(10)의 힌지부(12)와 각각 회동가능하게 고정되고, 판체(21)의 힌지부 반대편 단부에서 길이방향 양단에 홈부(23)와 돌출부(24)가 쌍을 이루어 형성된다.The plate body 21 is rotatably fixed to the hinge portion 12 of the duct body 10, and grooves 23 and the protrusions 24 are paired at both ends in the longitudinal direction at ends opposite to the hinge portion of the plate body 21. Formed.

각각 쌍을 이루는 판체(21)의 단부가 서로 맞닿을 때 홈부(23)에 돌출부(24)가 삽입되고, 홈부(23)에 돌출부(24)가 삽입되었을 때 홈부(23)와 돌출부(24)의 측부로 사각홀(25)이 서로 연통되도록 형성된다. 이때 사각홀(25)은 직각을 이루었을 경우에만 서로의 사각홀(25)의 모서리가 일치하도록 형성된다.The projections 24 are inserted into the grooves 23 when the ends of the pair of plate bodies 21, which are paired with each other, and the grooves 23 and the protrusions 24 when the protrusions 24 are inserted into the grooves 23, respectively. Square holes 25 are formed to communicate with each other. At this time, the square holes 25 are formed such that the corners of the square holes 25 coincide with each other only when they form a right angle.

그리고 십자몸체(11)에서 수평으로 돌출된 단부의 상부에 형성된 힌지부와 수직으로 돌출된 단부의 하단 양측에 형성된 힌지부에 스톱퍼(S)를 두어 90도 이상 회전하지 않게 구성한다.And the stopper (S) formed on both sides of the lower end of the vertically projecting end portion and the hinge portion formed on the horizontally projecting end of the cross body 11 is configured not to rotate more than 90 degrees.

이와 같이 십자몸체(11)의 수평으로 돌출된 단부 즉 3시와 9시 방향으로 돌출된 단부의 상부에 고정된 판체(21)는 돌출된 부분 상면에 놓여있다가 90도까지만 회전할 수 있으므로 돌출된 부분 상면과 판체(21)에 의하여 상부가 개방된 공간부를 만들게 되고, 수직으로 돌출된 단부 즉 12시방향으로 돌출된 부분의 상단 양측에 고정되는 판체(21)가 덮개 역할을 하게된다.Thus, the plate body 21 fixed to the upper part of the horizontally protruding end of the cross body 11, that is, the end protruding in the 3 o'clock and 9 o'clock directions is placed on the upper surface of the protruding part, and thus can only rotate up to 90 degrees. The upper part is opened by the upper part of the portion and the plate body 21, and the plate body 21 fixed to both ends of the vertically protruding end, that is, the upper part of the part protruding in the 12 o'clock direction serves as a cover.

그리고 수직으로 돌출된 단부의 하단 즉 6시 방향으로 돌출된 단부의 양측에 고정된 판체는 스톱퍼(S)에 의하여 수평 이하로 내려오지 못하게 되고, 측부로 개방구가 형성된 공간을 만들게 된다. And the plate body fixed to the lower end of the vertically protruding end, that is, both sides of the end protruding in the 6 o'clock direction can not be lowered below the horizontal by the stopper (S), to create a space in which the opening is formed in the side.

스톱퍼는 십자몸체(11)의 단부에 걸림턱을 만들어 더 이상 내려오지 못하게 하거나 힌지 자체가 90도만 움직이는 것을 사용하면 된다. 도 3과 도 4에 전술한 스톱퍼(S)를 일예로 도시하였으나, 이러한 형상에 구애받지 않고 판체(21)의 회전이 90도 이상 되지 않게 하는 구성이면 족하다.The stopper may be used to make the locking jaw at the end of the cross body 11 so that it does not come down anymore or the hinge itself moves only 90 degrees. Although the stopper S mentioned above was shown as an example in FIG. 3 and FIG. 4, it is sufficient if it is a structure which makes rotation of the plate body 21 more than 90 degree irrespective of this shape.

자석봉(30)은 단면이 사각으로 형성된 봉체의 단부에 손잡이(31)가 형성되고, 자성을 띄도록 형성되는데, 90도 단위로 회전되어 서로 사각홀(25)(26)이 일치되는 판체(21)의 사각홀(25)(26)을 동시에 관통하도록 자석봉(30)이 삽입된다.The magnet rod 30 has a handle 31 formed at the end of the rod formed in a rectangular cross section, is formed so as to have a magnetic, rotated in units of 90 degrees square plate (25, 26) are matched with each other ( The magnet rod 30 is inserted to penetrate the square holes 25 and 26 of the 21 at the same time.

자석봉(30)은 일단 삽입되면 자력에 의해 사각홀(25)(26)에 부착되어 고정되므로 손으로 힘을 주어 빼지 않는한 빠지지 않는다.Once inserted, the magnet bar 30 is attached to the square holes 25 and 26 by magnetic force and thus is not detached unless the magnetic rod 30 is applied by hand.

십자몸체(11)의 12시 방향으로 돌출된 돌출부 상단에 형성된 고정봉(13)의 나사산과 행거봉(1)의 단부에 형성된 나사산과 맞물리도록 나사산이 커플러(40)의 양측 홀의 내경에 각각 형성된다. 따라서 커플러(40)를 돌리면 행거봉(1)와 고정봉(13)에 동시에 체결되면서 고정된다.Threads are formed at the inner diameters of both holes of the coupler 40 so as to engage with the threads of the fixing rod 13 formed at the top of the protrusion projecting in the 12 o'clock direction of the cross body 11 and the threads formed at the ends of the hanger rod 1. do. Therefore, when the coupler 40 is turned, it is fixed while being simultaneously fastened to the hanger rod 1 and the fixed rod 13.
