상기한 바와 같이 본 발명은 상판(10)과 하판(11)의 중간에 접지부(13a)가 형성된 다수개의 리미트 스위치(13)가 고정축(19)에 결합되어지고 상기 리미트 스위치(13)의 접지부(13a)와 접지되도록 접지판(15)을 형성한 작동구(14)가 동일한 개수로 축봉(12)에 의해 축결합되고 상기 축봉(12)의 상단은 회전을 위한 베어링(41)을 장착한 고정판(40)에 끼워 상판(10)에 고정하고 하단은 일부가 상기 고정판(40)에 관통되면서 하판(11)에 돌출되게 끼워져 상기 고정판(40)을 하판(11)에 고정하고 상기 하판(11)에 돌출되게 장착된 축봉(12)의 하단에 평기어(18)를 결합하고 상기 평기어(18)와 맞물리도록 기어부(26)를 형성한 회전봉(25)을 내공간(22)을 형성한 본체(20)에 관통되게 끼워 일측 끝단은 상기 베어링(41)을 장착한 고정판(40)에 끼워 본체(20)에 결합하고 타측 끝단은 무대장치(100)와 연결된 케이블이 연결되도록 상기 고정판(40)에 관통되면서 본체(20)의 외부로 돌출되게 끼워져 상기 고정판(40)을 본체(20)에 고정토록 한 것이다.As described above, in the present invention, a plurality of limit switches 13 having a ground portion 13a formed in the middle of the upper plate 10 and the lower plate 11 are coupled to the fixed shaft 19, and the limit switch 13 The actuating tool 14 which forms the ground plate 15 so as to be grounded with the grounding part 13a is axially coupled by the shaft 12 in the same number, and the upper end of the shaft 12 has a bearing 41 for rotation. The fixing plate 40 is fixed to the upper plate 10 and the lower end is inserted through the fixing plate 40 so as to protrude into the lower plate 11 to fix the fixing plate 40 to the lower plate 11 and the lower plate. Coupling gear 18 is coupled to the lower end of the shaft rod 12 protrudingly mounted on the (11) and the rotating rod 25 formed with the gear portion 26 to be engaged with the spur gear 18, the inner space 22 The one end is inserted into the main body 20 formed therein to be coupled to the main body 20 by being fitted to the fixed plate 40 on which the bearing 41 is mounted, and the other end is a stage device 10. The cable connected to 0) is inserted through the fixing plate 40 to protrude out of the main body 20 so that the fixing plate 40 is fixed to the main body 20.

상기와 같은 본체(20)의 상측으로 하판(11)의 이면에 결합된 평기어(18)와 회전봉(25)의 기어부(26)가 웜기어식으로 맞물리도록 위치하여 하판(11)을 본체(20)의 상측으로 결합하고 상기 본체(20)에 뚜껑(30)이 결합토록 된 구조이다.The spur gear 18 coupled to the rear surface of the lower plate 11 and the gear portion 26 of the rotating rod 25 are engaged with the worm gear type to the upper side of the main body 20 as described above. 20) is coupled to the upper side of the structure to the lid 30 is coupled to the main body 20.

이때 상기 작동구(14)는 축봉(12)이 결합되는 축홈(14a)을 중심으로 일측이 절개되어 벌어지도록 날개면(14b)을 형성하고 상기 벌어지게 형성된 날개면(14b)의 양측으로 조임홈(14c)을 형성하여 상기 작동구(14)의 축홈(14a)에 축봉(12)을 결합하고 벌어진 날개면(14b)의 사이에 일측에 이탈방지홈(15b)을 형성한 접지판(15)을 끼운 후 양측으로 형성된 조임홈(14c)으로 볼트(16)와 너트(17)로 움직이지 않게 결합한 것이다.At this time, the operation port 14 forms a wing surface 14b so that one side is cut and opened about the shaft groove 14a to which the shaft bar 12 is coupled, and tightens to both sides of the wing surface 14b formed to be opened. A ground plate 15 in which a shaft 14 is coupled to the shaft groove 14a of the actuating tool 14 by forming a 14c, and a separation prevention groove 15b is formed at one side between the flared wing surfaces 14b. After inserting the bolt 16 and the nut 17 to be coupled to the fastening groove (14c) formed on both sides so as not to move.

상기와 같은 다수 개의 작동구(14)를 축봉(12)에 결합하여 볼트(16)와 너트(17)로 축봉(12)에 조임전까지 상기 축봉(12)에서 다양한 방향으로 회전이 가능하게 되는 것이고 상기 축봉(12)에 축결합되어진 다수 개의 작동구(14)를 무대상황에 맞게 무대장치(100)가 천천히 내려오거나 멈추거나 하는 등의 여러 단계로 작동되도록 축봉(12)에 다양한 방향으로 위치시킨 후 볼트(16)와 너트(17)를 조임하여 축봉(12)에 고정하여 축봉(12)이 회전할 때 작동구(14)가 동시에 회전이 되면서 각각의 다양한 방향으로 고정되어진 작동구(14)에 끼워진 접지판(15)이 리미트 스위치(13)에 접지되도록 한 것이다.The plurality of operation holes 14 as described above are coupled to the shaft 12 to be rotated in various directions in the shaft 12 until the bolt 16 and the nut 17 to tighten the shaft 12 before being tightened. Positioning the plurality of actuating holes 14 coupled to the shaft 12 in various directions such that the stage device 100 is slowly lowered or stopped in accordance with the stage situation to be operated in various stages. After tightening the bolt 16 and the nut 17 is fixed to the shaft 12, when the shaft 12 is rotated, the operating sphere 14 is rotated at the same time, the operation sphere 14 is fixed in each of various directions The ground plate 15 fitted in the ground is to be grounded to the limit switch (13).

이때 상기 접지판(15)은 리미트 스위치(13)의 접지부(13a)와 접지가 용이토록 일측을 절곡하여 절곡면(15a)을 형성하고 상기 작동구(14)의 일측 날개면(14b)에 접지판(15)의 절곡면(15a)이 안착되는 안착부(14d)를 형성하여 상기 안착부(14d)에 접지판(15)이 안착되도록 하여 흔들리지 않도록 한 것이다.At this time, the ground plate 15 is bent to one side of the ground portion (13a) of the limit switch 13 and easy to form a bent surface (15a) and to one side of the wing surface (14b) of the operating port (14) The ground plate 15 is seated on the seating portion 14d by forming a seating portion 14d on which the bent surface 15a of the ground plate 15 is seated so as not to shake.

이때 상기 접지판(15)의 미세조정을 위하여 날개면(14b)의 일측에 관통홈(14e)을 형성하고 상기 관통홈(14e)에 조임볼트(14f)를 결합하여 상기 조임볼트(14f)를 조임하면 조임볼트(14f)가 관통홈(14e)에 조임되면서 관통되어 조임볼트(14f)의 일단이 접지판(15)과 접촉되면서 상기 접지판(15)을 밀도록 하여 리미트스위치(13)의 접지부(13a)에 정확하게 접지되도록 미세조정되도록 한 것이다.At this time, the through plate (14e) is formed on one side of the wing surface (14b) for fine adjustment of the ground plate (15) and the tightening bolt (14f) by coupling the tightening bolt (14f) to the tightening bolt (14f) When tightening, the tightening bolt 14f is tightened to the through groove 14e and penetrates so that one end of the tightening bolt 14f contacts the ground plate 15 and pushes the ground plate 15 so that the limit switch 13 is closed. It is to be fine-tuned to be correctly grounded to the ground portion (13a).

따라서 도 4에 도시된 바와 같이 상기 작동구(14)가 회전되면서 작동구(14)의 안착부(14d)에 안착되어진 접지판(15)의 절곡면(15a)이 리미트 스위치(13)의 접지부(13a)와 접지가 용이토록 한 것이고 접지판(15)을 조임볼트(14f)를 이용하여 미세조정토록 하여 정확하게 접지되도록 한 것이다.Therefore, as shown in FIG. 4, the bent surface 15a of the ground plate 15, which is seated on the seating portion 14d of the actuating tool 14 while the actuating tool 14 is rotated, is brought into contact with the limit switch 13. The branch 13a and the ground are made easy, and the ground plate 15 is finely adjusted using the fastening bolts 14f to be grounded accurately.

이때 상기 도5에 도시된 바와 같이 본체(20)에 형성된 내공간(22) 일측에 격벽(23)을 형성하여 내공간(22)을 두 개로 분할하여 일측 내공간(22)의 모서리 부분에는 소정 높이의 결합봉(24)을 형성하고 중앙에 기어부(26)를 형성한 회전봉(25)이 관통되게 결합하여 하판(11)이 결합봉(24)에 소정 높이로 안착되면서 하판(11)의 이면에 형성된 평기어(18)와 회전봉(25)에 형성된 기어부(26)가 맞물리게 결합토록 한 것이다.In this case, as shown in FIG. 5, a partition wall 23 is formed at one side of the inner space 22 formed in the main body 20 to divide the inner space 22 into two, and a predetermined portion is formed at the corner portion of the one inner space 22. The lower bar 11 is seated at the predetermined height of the lower plate 11 by engaging the rotary bar 25 having a coupling rod 24 having a height and a gear bar 26 formed at the center thereof to penetrate therethrough. The spur gear 18 formed on the rear surface and the gear portion 26 formed on the rotating rod 25 are engaged to engage.

또한 타측 내공간(22)에는 리미트 스위치(13)와 연결된 전선을 수납하여 상기 전선을 외부로 인출하는 인출홈(27a)을 형성하여 조임너트(28)와 결합되는 인출캡(27)을 본체(20)에 결합토록 하여 외관상 보기 좋게 한 것이다.In addition, the other inner space 22 receives the wire connected to the limit switch 13 to form a withdrawal groove 27a for drawing out the wire to the outside, and the take-out cap 27 coupled with the tightening nut 28 is the main body ( 20) to make it look good.

또한 이때 상기 본체(20)의 양측으로 결합홈(21a)을 형성한 돌출편(21)을 형성하고 상기 돌출편(21)과 맞물리도록 뚜껑(30)의 하단부에 결합홈(31a)을 형성한 결합편(31)을 형성하여 나사 등으로 결합토록 한 것이다.In addition, at this time, to form a protrusion piece 21 formed with a coupling groove 21a on both sides of the main body 20 and to form a coupling groove 31a at the lower end of the lid 30 to be engaged with the protrusion piece 21. The coupling piece 31 is formed to be coupled with a screw or the like.

따라서 상술한 바와 같이 본체(20)의 내공간(22)에 장착되어 일부가 외측으로 돌출되게 형성된 회전봉(25)에 케이블을 연결하여 상기 회전봉(25)을 회전하면 회전봉(25)에 형성된 기어부(26)와 맞물려진 평기어(18)가 회전되고 상기 평기어(18)가 결합된 축봉(12)이 회전하면서 상기 축봉(12)에 다양한 방향으로 조임되어진 다수 개의 작동구(14)가 회전되어 작동구(14)에 끼워진 접지판(15)과 리미트 스위치(13)의 접지부(13a)가 접지되도록 한 것이다.Therefore, as described above, when the rotary rod 25 is rotated by connecting a cable to the rotary rod 25 mounted in the inner space 22 of the main body 20 so as to protrude outward, the gear unit formed on the rotary rod 25 is formed. As the spur gear 18 engaged with the 26 is rotated, and the shaft rod 12 to which the spur gear 18 is coupled is rotated, a plurality of operating holes 14 fastened to the shaft rod 12 in various directions are rotated. Thus, the ground plate 15 fitted in the operation port 14 and the ground portion 13a of the limit switch 13 are grounded.

따라서 하나의 축으로 결합된 리미트 스위치(13)로 인해 무대상황에 맞게 무대장치가 여러 단계의 속도로 승,하강되어지는 것이다. Therefore, due to the limit switch 13 coupled to one axis, the stage device is raised and lowered at various speeds according to the stage situation.
