도 1 내지 도 8을 참조하면, 본 발명의 바람직한 실시예에 따른 건축물 옥외형 통신장비의 케이블 인입장치는, 함체(100), 커버(200), 승강부재(300), 회전축(400) 및 에어팩(700)을 포함하는 구성요소로 이루어지며, 이를 상세히 설명하면 다음과 같다.1 to 8, the cable entry device of the outdoor communication equipment of the building according to a preferred embodiment of the present invention, the enclosure 100, the cover 200, the lifting member 300, the rotation shaft 400 and the air pack It consists of a component including 700, and this will be described in detail as follows.

함체(100)는, 내부 수용공간이 마련된 사각의 박스 형태로 이루어지며, 전면이 개방된 전면 개구부(110)가 형성된다. 그리고, 함체(100)의 내부 수용공간에는 접속구(11)가 마련된 통신장비(10)가 설치된다. 여기서, 통신장비(10)는 공지된 옥외에서 운용되는 통신장비(10)로 이하 상세한 설명은 생략한다.The enclosure 100 is made in the shape of a square box in which an internal accommodation space is provided, and a front opening 110 with an open front surface is formed. In addition, the communication equipment 10 provided with the connection port 11 is installed in the interior accommodation space of the enclosure 100. Here, the communication equipment 10 is a known communication equipment 10 operated outdoors, and a detailed description thereof will be omitted.

그리고, 함체(100)의 내부에 수용된 통신장비(10)를 운용하기 위한 케이블(C)이 함체(100)의 내부로 인입되는 관통홀(120)이 함체(100)의 하면에 형성된다. 이러한 관통홀(120)을 통해 케이블(C)이 함체(100)의 내부로 인입되어 함체(100)의 내부에 설치된 통신장비(10)의 접속구(11)에 케이블(C)이 접속되는 것이다. 이때, 케이블(C)은 전원선, 안테나, 신호선 및 접지선 등이 될 수 있다.In addition, a through hole 120 through which a cable C for operating the communication equipment 10 accommodated in the enclosure 100 is introduced into the interior of the enclosure 100 is formed on the lower surface of the enclosure 100. The cable (C) is introduced into the interior of the enclosure 100 through the through hole 120, and the cable C is connected to the connection port 11 of the communication equipment 10 installed inside the enclosure 100. At this time, the cable C may be a power line, an antenna, a signal line, and a ground line.

여기서, 후술하는 승강부재(300)가 관통홀(120)에 나선결합되도록 관통홀(120)의 내경을 따라 나선이 형성된다.Here, a spiral is formed along the inner diameter of the through hole 120 so that the elevating member 300 to be described later is helically coupled to the through hole 120.

이처럼, 케이블(C)이 함체(100)의 하측에서 함체(100)의 내부로 상향 인입되기 때문에 우천시에도 건축물의 옥외에 마련된 함체(100)에 형성된 관통홀(120)이 함체(100)의 하면에 형성되기 때문에 관통홀(120)을 통해 빗물이 함체(100)의 내부로 유입되는 것을 방지할 수 있게 된다.In this way, since the cable (C) is drawn upward into the interior of the enclosure 100 from the lower side of the enclosure 100, the through hole 120 formed in the enclosure 100 provided outdoors of the building even in rainy weather is the lower surface of the enclosure 100 Since it is formed in, it is possible to prevent rainwater from flowing into the interior of the enclosure 100 through the through hole 120.

커버(200)는, 함체(100)의 전면에 설치되어 함체(100)의 전면 개구부(110)를 개폐한다.The cover 200 is installed on the front surface of the housing 100 to open and close the front opening 110 of the housing 100.

부연하면, 커버(200)는, 함체(100)의 개방된 전면에 힌지에 의해 회전 가능하게 결합되어 함체(100)의 전면 개구부(110)를 개방 또는 차폐할 수 있다.In other words, the cover 200 may be rotatably coupled to the opened front surface of the enclosure 100 by a hinge to open or shield the front opening 110 of the enclosure 100.

즉, 커버(200)의 측단이 힌지에 의해 결합되어 함체(100)의 전후방으로 회전하여 함체(100)의 전면 개구부(110)를 개폐하도록 구성될 수 있고, 커버(200)와 함체(100)가 서로 맞닿는 커버(200)의 둘레 또는 함체(100)의 둘레에는 커버(200)가 함체(100)를 밀폐하였을 때, 기밀하는 씰링부재가 구비될 수 있다.That is, the side end of the cover 200 may be coupled by a hinge and rotated in the front and rear of the housing 100 to open and close the front opening 110 of the housing 100, and the cover 200 and the housing 100 When the cover 200 seals the enclosure 100 around the cover 200 or the enclosure 100 in contact with each other, an airtight sealing member may be provided.

또한, 커버(200)에는 함체(100)를 밀폐하였을 때, 커버(200)의 임의의 개방을 방지하기 위한 자물쇠와 같은 잠금수단이 설치될 수 있다.In addition, a locking means such as a lock may be installed on the cover 200 to prevent any opening of the cover 200 when the enclosure 100 is sealed.

승강부재(300)는, 함체(100)의 내부로 케이블(C)을 인입시키는 역할을 하는 부재로써, 속이 빈 중공의 관 형태로 이루어지며, 함체(100)의 관통홀(120)에 나선결합되고, 후술하는 회전축(400)에 스크류 기어 치합되도록 외경을 따라 나선이 형성된다.The elevating member 300 is a member that serves to lead the cable C into the interior of the enclosure 100, and is formed in the form of a hollow hollow tube, and is helically coupled to the through hole 120 of the enclosure 100 And, a spiral is formed along the outer diameter so that the screw gear is engaged with the rotation shaft 400 to be described later.

부연하면, 승강부재(300)가 함체(100)의 하면에 형성된 관통홀(120)을 수직으로 관통하여 관통홀(120)의 내경에 나선결합되며, 승강부재(300)의 내부를 케이블(C)이 수직으로 관통하여 승강부재(300)의 내부에 케이블(C)이 끼워지는 것이다. 이때, 승강부재(300)의 상단부와 하단부에는 플랜지(310, 320)가 각각 형성된다.In addition, the elevating member 300 vertically penetrates the through hole 120 formed on the lower surface of the housing 100 and is helically coupled to the inner diameter of the through hole 120, and the inside of the elevating member 300 is a cable (C ) Is vertically penetrated and the cable (C) is inserted into the inside of the elevating member 300. At this time, flanges 310 and 320 are formed at the upper and lower ends of the elevating member 300, respectively.

또한, 승강부재(300)가 함체(100)에 형성된 관통홀(120)에 나선결합되기 때문에 승강부재(300)의 외경과 관통홀(120)의 내경 사이가 기밀되어 승강부재(300)와 관통홀(120) 간의 틈을 통해 외부의 수분이 함체(100) 내부로 침투되는 것을 방지할 수 있게 된다.In addition, since the lifting member 300 is helically coupled to the through hole 120 formed in the housing 100, the outer diameter of the lifting member 300 and the inner diameter of the through hole 120 are airtight to penetrate the lifting member 300 It is possible to prevent external moisture from penetrating into the housing 100 through the gap between the holes 120.

여기서, 승강부재(300)의 상단부에 형성된 플랜지(310)에는 제1 플랜지 볼 베어링(500)이 볼트와 너트에 의해 플랜지 결합된다.Here, the first flange ball bearing 500 is flange-coupled to the flange 310 formed on the upper end of the lifting member 300 by a bolt and a nut.

그리고, 승강부재(300)의 하단부에 형성된 플랜지(320)에는 제2 플랜지 볼 베어링(600)이 볼트와 너트에 의해 플랜지 결합된다.In addition, a second flange ball bearing 600 is flange-coupled to the flange 320 formed at the lower end of the elevating member 300 by a bolt and a nut.

회전축(400)은, 함체(100)의 관통홀(120)을 통해 함체(100)의 하측으로 노출된 승강부재(300)에 직교한 상태로 승강부재(300)의 외경에 스크류 기어 치합되어 회전축(400)의 회전 방향에 따라 승강부재(300)를 정역회전시켜 승강부재(300)를 승강시키는 역할을 한다.The rotating shaft 400 is a screw gear engaged with the outer diameter of the lifting member 300 in a state perpendicular to the lifting member 300 exposed to the lower side of the enclosure 100 through the through hole 120 of the enclosure 100 It serves to elevate the elevating member 300 by rotating the elevating member 300 forward and backward according to the rotation direction of the 400.

여기서, 회전축(400)은 외경을 따라 나선이 형성되는데, 이는 회전축(400)이 승강부재(300)의 외경에 스크류 기어 치합되어 회전축(400)의 회전 방향에 따라 승강부재(300)를 수직으로 승강시키기 위함이다.Here, the rotation shaft 400 is formed in a spiral along the outer diameter, which is the rotation shaft 400 is screwed to the outer diameter of the lifting member 300 is engaged with the lifting member 300 vertically according to the rotation direction of the rotation shaft 400. It is for lifting.

부연하면, 회전축(400)은 관통홀(120)이 형성된 함체(100)의 하측에 수평으로 위치하게 되며, 함체(100)의 하면에 형성된 관통홀(120)에 수직으로 나선결합되어 함체(100)의 하측으로 노출된 승강부재(300)와 직교하여 승강부재(300)의 외경에 회전축(400)의 외경이 서로 스크류 기어 치합하게 된다.In addition, the rotation shaft 400 is positioned horizontally under the enclosure 100 in which the through hole 120 is formed, and is helically coupled to the through hole 120 formed on the lower surface of the enclosure 100 to be helically coupled to the enclosure 100 ), the outer diameter of the rotation shaft 400 is perpendicular to the outer diameter of the lifting member 300 exposed to the lower side of the screw gear.

이때, 회전축(400)은 함체(100)의 외측 하면에 고정된 거치대(130)에 의해 회전가능하게 거치된다.At this time, the rotation shaft 400 is rotatably mounted by a holder 130 fixed to the outer lower surface of the housing 100.

부연하면, 함체(100)의 외측 하면에 서로 이격한 상태로 함체(100)에 고정된 한 쌍의 거치대(130) 사이에 회전축(400)의 양 끝단부가 거치된 상태로 회전축(400)이 정역회전되는 것이다.In addition, the rotation shaft 400 is in a state where both ends of the rotation shaft 400 are mounted between a pair of cradles 130 fixed to the enclosure 100 in a state spaced apart from each other on the outer lower surface of the enclosure 100. It is rotated.

이는 회전축(400)이 스크류 기어 치합된 승강부재(300)를 회전시키기 위해 회전축(400)을 정역방향으로 회전시키면 회전축(400)이 거치대(130)를 향해 전후진 되지 않도록 거치대(130)에 의해 회전축(400)의 위치가 고정되고 회전축(400)이 제자리에서만 회전되게 한 것이다.This is because when the rotation shaft 400 is rotated in the forward and reverse direction in order to rotate the elevating member 300 in which the rotation shaft 400 is engaged with the screw gear, the rotation shaft 400 is prevented from moving forward and backward toward the mount 130 by the holder 130. The position of the rotation shaft 400 is fixed and the rotation shaft 400 rotates only in place.

즉, 회전축(400)이 일방향 회전되면 회전축(400)에 스크류 기어 치합된 승강부재(300) 또한 일방향 회전되면서 함체(100)의 내측을 향해 상승되고, 반대로 회전축(400)이 역방향 회전되면 회전축(400)에 스크류 기어 치합된 승강부재(300) 또한 역방향 회전되면서 함체(100)의 하측을 향해 하강되는 것이다.That is, when the rotation shaft 400 is rotated in one direction, the elevating member 300 engaged with the screw gear to the rotation shaft 400 is also rotated in one direction and rises toward the inside of the housing 100, and when the rotation shaft 400 is rotated in the reverse direction, The lifting member 300 engaged with the screw gear 400 is also lowered toward the lower side of the housing 100 while rotating in the reverse direction.

여기서, 회전축(400)의 외측면에는 사용자가 파지한 상태로 회전축(400)을 용이하게 회전시킬 수 있도록 회전축(400)의 외측면에는 복수의 파지봉(410)이 더 형성될 수 있다.Here, a plurality of gripping rods 410 may be further formed on the outer surface of the rotation shaft 400 so that the rotation shaft 400 can be easily rotated in a state held by the user on the outer surface of the rotation shaft 400.

에어팩(700)은, 승강부재(300)의 내부에 수용되며, 내부 수용공간이 마련되고 케이블(C)을 감싸도록 중공의 형태로 이루어진다.The air pack 700 is accommodated in the elevating member 300, has an internal accommodation space, and has a hollow shape so as to surround the cable C.

부연하면, 에어팩(700)의 내부에 공기가 주입되면, 에어팩(700)이 승강부재(300)의 내부에서 확장되는 것이다.In other words, when air is injected into the air pack 700, the air pack 700 expands inside the elevating member 300.

여기서, 에어팩(700)의 내부에는, 에어팩(700)의 내부 수용공간을 내측과 외측의 이중 공간으로 구획하는 격벽(710)이 형성된다.Here, inside the air pack 700, a partition wall 710 is formed that divides the inner accommodation space of the air pack 700 into a double space inside and outside the air pack 700.

부연하면, 에어팩(700)은 제1 에어팩(720)과 제2 에어팩(730)으로 구성된다.In other words, the air pack 700 includes a first air pack 720 and a second air pack 730.

즉, 제1 에어팩(720)은, 격벽(710)을 기준으로 에어팩(700)의 내부 내측에 형성되며, 공기가 주입되는 제1 주입구(721)가 외측면에 형성된다.That is, the first air pack 720 is formed inside the air pack 700 with respect to the partition wall 710, and the first injection hole 721 through which air is injected is formed on the outer surface.

이때, 제1 주입구(721)를 통해 공기가 주입되면, 케이블(C)을 향해 확장되면서 에어팩(700)의 내경면이 케이블(C)의 외경면에 밀착되어 케이블(C)을 고정시키게 되면서 케이블(C)과 에어팩(700) 간의 틈을 기밀하게 된다.At this time, when air is injected through the first injection port 721, the inner diameter surface of the air pack 700 is in close contact with the outer diameter surface of the cable C as it expands toward the cable C, thereby fixing the cable C. The gap between (C) and the air pack 700 is sealed.

그리고, 제2 에어팩(730)은, 격벽(710)을 기준으로 에어팩(700)의 내부 외측에 형성되며, 공기가 주입되는 제2 주입구(731)가 외측면에 형성된다.In addition, the second air pack 730 is formed inside and outside the air pack 700 based on the partition wall 710, and a second inlet 731 through which air is injected is formed on the outer surface.

이때, 제2 주입구(731)를 통해 공기가 주입되면, 승강부재(300)를 향해 확장되면서 에어팩(700)의 외경면이 승강부재(300)의 내경면에 밀착되어 에어팩(700)이 승강부재(300)의 내부에 고정되고 에어팩(700)과 승강부재(300) 간의 틈을 기밀하게 된다.At this time, when air is injected through the second injection port 731, the outer diameter surface of the air pack 700 is in close contact with the inner diameter surface of the lifting member 300 while expanding toward the lifting member 300 so that the air pack 700 is moved to the lifting member. It is fixed to the inside of the 300, and the gap between the air pack 700 and the elevating member 300 is sealed.

따라서, 케이블(C)과 에어팩(700) 간이 기밀되고 에어팩(700)과 승강부재(300) 간이 기밀되기 때문에 승강부재(300)의 내부를 통해 외부의 수분이 함체(100) 내부로 침투되는 것을 방지할 수 있게 된다.Therefore, since the cable (C) and the air pack 700 is airtight and the air pack 700 and the elevating member 300 are airtight, external moisture is prevented from penetrating into the housing 100 through the interior of the elevating member 300. Can be prevented.

한편, 제1 플랜지 볼 베어링(500)과 제2 플랜지 볼 베어링(600)이 승강부재(300)의 상하단에 각각 플랜지 결합되고, 제2 플랜지 볼 베어링(600)의 내륜과 승강부재(300)의 내부와 제1 플랜지 볼 베어링(500)의 내륜을 연속으로 관통하여 제2 플랜지 볼 베어링(600)의 내륜의 내측과 승강부재(300)의 내측과 제1 플랜지 볼 베어링(500)의 내륜의 내측에 에어팩(700)이 수용되고, 에어팩(700)의 내부를 케이블(C)이 관통하여 에어팩(700)의 내측에 케이블(C)이 수용된 상태에서 회전축(400)의 회전에 의해 승강부재(300)가 회전되면, 승강부재(300)에 결합된 제1 플랜지 볼 베어링(500)과 제2 플랜지 볼 베어링(600)에 의해 승강부재(300)의 내부의 케이블의 꼬임이 방지된다.Meanwhile, the first flange ball bearing 500 and the second flange ball bearing 600 are flange-coupled to the upper and lower ends of the lifting member 300, respectively, and the inner ring of the second flange ball bearing 600 and the lifting member 300 The inside and the inner ring of the first flange ball bearing 500 are continuously penetrated to the inside of the inner ring of the second flange ball bearing 600 and the inside of the lifting member 300 and the inner ring of the first flange ball bearing 500 The air pack 700 is accommodated in the air pack 700, the cable C penetrates the inside of the air pack 700, and the elevating member 300 is rotated by the rotation of the rotary shaft 400 while the cable C is accommodated inside the air pack 700. When) is rotated, twisting of the cable inside the lifting member 300 is prevented by the first flange ball bearing 500 and the second flange ball bearing 600 coupled to the lifting member 300.

이는 승강부재(300)가 정역회전되면서 승강되면, 제1 플랜지 볼 베어링(500)의 외륜과 제2 플랜지 볼 베어링(600)의 외륜은 승강부재(300)의 회전 방향과 동일하게 함께 회전되지만, 에어팩(700)을 감싸는 제1 플랜지 볼 베어링(500)의 내륜과 제2 플랜지 볼 베어링(600)의 내륜은 회전되지 않기 때문에 케이블(C)이 승강부재의 회전에 연동하여 함께 회전되지 않기 때문에 케이블(C)의 꼬임이 방지되는 것이다.This is when the lifting member 300 is raised and lowered while rotating forward and backward, the outer ring of the first flange ball bearing 500 and the outer ring of the second flange ball bearing 600 are rotated together in the same direction as the rotation direction of the lifting member 300, Since the inner ring of the first flange ball bearing 500 surrounding the air pack 700 and the inner ring of the second flange ball bearing 600 are not rotated, the cable C is not rotated together with the rotation of the lifting member. (C) is prevented from twisting.

이하, 본 발명의 실시예에 따른 건축물 옥외형 통신장비의 케이블 인입장치의 작동 상태를 상세히 설명한다.Hereinafter, the operating state of the cable entry device of the outdoor communication equipment of a building according to an embodiment of the present invention will be described in detail.

Each of the 600 is flange-coupled, and the air pack 700 is accommodated inside the elevating member 300.

그 다음, 케이블(C)이 제2 플랜지 볼 베어링(600)과 에어팩과 제1 플랜지 볼 베어링(500)의 중심을 차례로 관통하여 케이블(C)의 상단부가 제1 플랜지 볼 베어링(500)을 통과하여 승강부재(300)의 상측으로 노출된 상태로 에어팩(700)의 내측에 끼움된다.Then, the cable C passes through the center of the second flange ball bearing 600 and the air pack and the first flange ball bearing 500 in order, and the upper end of the cable C passes through the first flange ball bearing 500 Thus, it is fitted inside the air pack 700 in a state exposed to the upper side of the lifting member 300.

그 다음, 공기 펌프와 같은 공기주입수단으로 제1 에어팩(720)의 제1 주입구(721)를 통해 공기를 주입하여 제1 에어팩(720)을 팽창시켜 케이블(C)을 견고히 고정시킨다.Thereafter, air is injected through the first inlet 721 of the first air pack 720 by means of an air injection means such as an air pump, and the first air pack 720 is inflated to firmly fix the cable C.

그 다음, 회전축(400)을 일방향 회전시켜 승강부재(300)를 함체(100)의 내부를 향해 상승시킴으로써 케이블(C)이 함체(100)의 내부에 설치된 통신장비(10)를 향해 인입되도록 한다. 이때, 승강부재(300)가 회전되더라도 제1 플랜지 볼 베어링(500)과 제2 플랜지 볼 베어링(600)에 의해 케이블(C)은 회전되지 않게 된다.Then, by rotating the rotation shaft 400 in one direction to raise the lifting member 300 toward the inside of the enclosure 100, the cable C is drawn in toward the communication equipment 10 installed inside the enclosure 100. . At this time, even if the lifting member 300 is rotated, the cable C is not rotated by the first flange ball bearing 500 and the second flange ball bearing 600.

마지막으로, 공기 펌프와 같은 공기주입수단으로 제2 에어팩(730)의 제2 주입구(731)를 통해 공기를 주입하여 제2 에어팩(730)을 팽창시켜 에어팩(700)이 승강부재(300)에 밀착되도록 한다.Finally, by injecting air through the second inlet 731 of the second air pack 730 with an air injection means such as an air pump, the second air pack 730 is inflated so that the air pack 700 is transferred to the elevating member 300. Keep it close.
