     본 발명의 구성은 맨홀뚜껑(10)의 손잡이 삽입공(11)에 끼워져 승하강 되며, 하부에 경사면(34)이 형성된 손잡이(30); 전방몸체(41)와 후방몸체(42) 및 상기 전방몸체(41)와 후방몸체(42) 사이에 걸림턱(43)을 가지며, 상기 후방몸체의 상단부에 상기 손잡이(30)의 경사면(34)과 접하여 안내하는 상부경사면(42a)을 형성하여 상기 손잡이(30)의 승하강 동작에 의해 맨홀뚜껑(10) 가장자리로 진퇴하는 걸쇠(40); 상기 걸쇠(40)의 진퇴가 가능하게 지지하는 지지부(60); 맨홀받침대(20)의 내주연에 형성되어 상기 손잡이(30)에 의해 전진하는 걸쇠(40)의 일단이 삽입 걸림되는 요홈(21); 상기 (40)를 후퇴시키는 스프링(50);으로 구성된다. 
     이와 같은 구조의 맨홀뚜껑 잠금장치는 맨홀뚜껑을 개방하기 위해 손잡이를 당기는 행위에 의해 걸쇠가 후퇴하여 맨홀뚜껑의 잠금 상태가 해제되고, 반대로 맨홀뚜껑을 맨홀받침대에 안착 후 손잡이를 하강 삽입시키는 행위에 의해 걸쇠가 요홈에 걸려 잠금되므로 맨홀뚜껑 잠금조작이 매우 용이한 장점이 있다. 
     또한, 걸쇠가 잠금된 후에는 스프링의 탄성력에 의해 상기 맨홀받침대의 요홈을 압박하고 있기 때문에 견고한 잠금상태를 유지할 뿐만 아니라 걸쇠의 전방몸 체 선단에 형성된 경사면에 의해 맨홀뚜껑을 강제 하강시키는 작용을 하므로 맨홀뚜껑과 맨홀받침대 간의 밀착력이 높아지게 되고 또 두 몸체 사이에 패킹을 개재할 경우에는 수밀성이 확보되는 장점이 있다. 
     또한, 개방장치가 맨홀뚜껑 내부에 설치되므로 이물질이 끼지 않아 원활한 조작이 지속되는 효과가 있다.
