본 발명은 공동주택 단지 내 맨홀 뚜껑을 고정하는 잠금장치에 관한 것으로서, 특히 열림키 손잡이, 열림키 연결구, 체인 고리, 잠금키 및 스프링으로 일체 작동되는 구조로 가져, 평상시는 맨홀 뚜껑 덮개에 맨홀 뚜껑이 이탈되지 않도록 고정되고, 열림키 손잡이를 통해 열림키 연결구를 승,하강시키므로 잠금키를 작동시켜 맨홀 뚜껑을 열 수 있는 구조로 구성된 체인 고리를 이용한 공동주택 단지 내 맨홀 뚜껑 잠금구조에 관한 것이다.The present invention relates to a locking device for fixing a manhole cover in a multi-family housing complex, in particular, having a structure that is integrally operated by an opening key handle, an opening key connector, a chain ring, a locking key and a spring, and usually a manhole cover on a manhole cover It is fixed so as not to be separated, and the opening and closing the opening key connector through the opening key handle relates to a manhole cover locking structure in the apartment complex using a chain ring configured to open the manhole cover by operating the locking key.
일반적으로 공동주택 단지 내에서는 다수개의 맨홀이 설치되고, 상기 맨홀은, 맨홀 몸체, 맨홀 뚜껑 덮개 및 맨홀 뚜껑이 설치되는 구조로 구성된다.In general, a plurality of manholes are installed in the apartment complex, and the manholes are configured to have a manhole body, a manhole cover, and a manhole cover.
도 1에서 알 수 있듯이, 공동주택 단지 내에 설치되는 맨홀은, 도로(10)의 지중에 다수개가 매설되는 한편, 도로(10)에는 노면과 높이가 일치되도록 맨홀 뚜껑 덮개(20)의 중앙에 맨홀 뚜껑(30)이 설치되며, 도로(10)를 주행하던 차량(40)은 도면과 같이 주행하는 경우 맨홀 뚜껑(30)이 열려 안전 사고 및 차량의 파손 사고가 발생되는 실정이다.As can be seen in Figure 1, the manhole installed in the multi-family housing complex, a plurality of manholes are buried in the ground of the road 10, while the road 10 is a manhole in the center of the manhole cover 20 so that the height and the road surface When the lid 30 is installed and the vehicle 40 traveling on the road 10 is driven as shown in the drawing, the manhole cover 30 is opened to cause a safety accident and a breakage accident of the vehicle.
본 발명은 상술한 문제점을 감안하여, 본 발명은, 평상시는 맨홀 뚜껑 덮개에 맨홀 뚜껑이 잠금키에 의해 고정되고, 맨홀을 점검 또는 수리하는 경우 열림키 손잡이를 통해 맨홀 뚜껑을 오픈시켜 내부로 진,출입할 수 있도록 구성하므로, 발생될 수 있는 안전 사고 및 차량 파손 사고를 미연에 방지할 수 있도록 하는 체인 고리를 이용한 공동주택 단지 내 맨홀 뚜껑 잠금구조를 제공함을 그 목적으로 한다.In view of the above-described problems, the present invention, the manhole cover is usually fixed to the manhole cover cover by the locking key, when the manhole is checked or repaired by opening the manhole cover through the open key handle to move inwards. Since it is configured to be accessible, it is an object of the present invention to provide a manhole cover locking structure in a multi-family housing complex using a chain ring to prevent a possible safety accident and vehicle damage accident in advance.
본 발명은 상술한 목적 달성을 위해, 본 발명은, 맨홀 뚜껑 덮개의 잠금키홀에 맨홀 뚜껑의 잠금키가 고정되어 평상시 잠금 상태가 유지되고, 열림키 손잡이가 맨홀 뚜껑의 중앙 나사홀에 체결되어 열림 상태로 내부 열림키 연결구, 체인 고리, 잠금키 및 스프링을 작동시키는 구조를 그 요지로 한다.The present invention, in order to achieve the above object, the present invention, the lock key of the manhole cover is fixed to the lock keyhole of the manhole cover, the usual lock state is maintained, the open key handle is opened by fastening to the central screw hole of the manhole cover Its main structure is to operate the internal opening key connector, the chain loop, the locking key and the spring in the state.
이하, 첨부 도면을 참조하여 본 발명의 구성을 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated with reference to an accompanying drawing.
도 2는 본 발명의 맨홀 뚜껑 잠금장치의 분해 사시도이고, 도 3은 본 발명의 맨홀 뚜껑 잠금장치의 분해 상태를 나타내는 도면이다. Figure 2 is an exploded perspective view of the manhole cover locking device of the present invention, Figure 3 is a view showing an exploded state of the manhole cover locking device of the present invention.
맨홀은, 맨홀 몸체의 중앙에 관통홀이 형성되고, 그 관통홀의 주위에 맨홀 뚜껑 덮개(100)가 안착되는 한편, 상기 맨홀 뚜껑 덮개(100)는, 외주면에 다수개의 잠금키홀(110)이 형성되고, 내측 중앙으로 향하여 절곡되는 단턱부가 형성되어 상부에 맨홀 뚜껑(200)이 안착된다.The manhole has a through hole formed in the center of the manhole body, and the manhole cover 100 is seated around the through hole, while the manhole cover 100 has a plurality of lock key holes 110 formed on an outer circumferential surface thereof. The stepped portion bent toward the inner center is formed, and the manhole cover 200 is seated thereon.
상기 맨홀 뚜껑(200)에는 중앙에 나사홀(210)이 형성되고, 외주면에 90각도로 잠금키(600)가 돌출되어 맨홀 뚜껑 덮개(100)의 잠금키홀(110)에 결합된다.The manhole cover 200 is formed with a screw hole 210 in the center, 90 on the outer peripheral surface The locking key 600 protrudes at an angle and is coupled to the locking keyhole 110 of the manhole cover 100.
즉, 상기 맨홀 뚜껑(200)은, 중앙 나사홀(210)에 열림키 연결구(400)가 삽입되어 고정되고, 상면 하부 내측에 90각도로 절곡되어 ㄷ홈부가 형성되도록 돌출턱(220)이 도 3과 같이 외주면과 그 내측으로 일정거리 이격되어 형성되며, 열림키 연결구(400)에 체인 고리(500)가 결합되고, 체인 고리(500)에 잠금키(600)가 결합되어 돌출턱(220)을 관통하는 한편, 상기 맨홀 뚜껑(200)은, 잠금키(600)에 스프링 지지구(650)와 스프링(700)이 연결되어 평상시 잠금키(600)가 맨홀 뚜껑(200)의 외주면으로 돌출되도록 형성된다.That is, the manhole cover 200 is fixed to the opening key connector 400 is inserted into the central screw hole 210, 90 in the lower inside of the upper surface Protruding jaw 220 is bent at an angle to form a c groove portion is formed to be spaced apart a predetermined distance to the outer peripheral surface and the inside as shown in Figure 3, the chain ring 500 is coupled to the opening key connector 400, the chain ring 500 Lock key 600 is coupled to the through-projection jaw 220, while the manhole cover 200, the spring support 650 and the spring 700 is connected to the lock key 600 is normally locked The key 600 is formed to protrude to the outer circumferential surface of the manhole cover 200.
상기 맨홀 뚜껑 덮개(100)와 맨홀 뚜껑(200)은, 평상시 잠금키(600)로 상호 체결되어 고정되고, 열림키 손잡이(300)가 T 자형 형태로 형성되고, 하부에 볼트부(310)가 형성되어 나사홀(210)에 결합된 열림키 연결구(400)를 상,하부로 승하강시키게 된다.The manhole cover 100 and the manhole cover 200 is usually fastened and fixed to each other by the locking key 600, the open key handle 300 is formed in a T-shape, the lower portion of the bolt 310 It is formed to raise and lower the opening key connector 400 coupled to the screw hole 210 up and down.
즉, 상기 맨홀 뚜껑(200)의 나사홀(210)에 열림키 손잡이(300)를 결합시켜 시계 방향으로 돌리면 열림키 연결구(400)와 연결된 체인 고리(500)가 아래측으로 밀리고, 반시계 방향으로 돌리면 그 반대로 작동되는 한편, 체인 고리(500)가 아래방향으로 밀리면 스프링(700)이 축소되고, 잠금키(600)가 안측으로 들어가 맨홀 뚜껑(200)이 맨홀 뚜껑 덮개(100)에서 이탈되도록 작동된다.That is, when the opening key knob 300 is coupled to the screw hole 210 of the manhole cover 200 and turned clockwise, the chain ring 500 connected to the opening key connector 400 is pushed downward, and counterclockwise. When turned, the reverse operation, while the chain ring 500 is pushed downward, the spring 700 is reduced, the locking key 600 is moved to the inner side so that the manhole cover 200 is released from the manhole cover 100 do.
상술한 바와 같이, 상기 맨홀 뚜껑 덮개(100)의 잠금키홀(110)에 맨홀 뚜껑(200)의 잠금키(600)가 고정되어 평상시 잠금 상태가 유지되고, 열림키 손잡이(300)가 맨홀 뚜껑(200)의 중앙 나사홀(210)에 체결되어 열림 상태로 내부 열림키 연결구(400), 체인 고리(500), 잠금키(600) 및 스프링(700)을 작동시키게 된다.As described above, the lock key 600 of the manhole cover 200 is fixed to the lock keyhole 110 of the manhole cover cover 100 so that the normally locked state is maintained, and the opening key handle 300 is the manhole cover ( It is fastened to the central screw hole 210 of the 200 to operate the inner opening key connector 400, the chain ring 500, the locking key 600 and the spring 700 in the open state.
상술한 본 발명의 구성에 따른 효과를 하기에 설명한다.The effects of the above-described configuration of the present invention will be described below.
본 발명은, 평상시는 맨홀 뚜껑 덮개에 맨홀 뚜껑이 잠금키에 의해 고정되고, 맨홀을 점검 또는 수리하는 경우 열림키 손잡이를 통해 맨홀 뚜껑을 오픈시켜 내부로 진,출입할 수 있도록 구성하므로, 발생될 수 있는 안전 사고 및 차량 파손 사고를 미연에 방지할 수 있는 효과를 갖는다.The present invention, the manhole cover is usually fixed to the manhole cover cover by the locking key, when the manhole is checked or repaired, so that the manhole cover through the opening key handle to open and move in and out, so that the generated It is possible to prevent a safety accident and a vehicle damage accident in advance.
