下構造物用錠機構。[Claims for Utility Model Registration] (1) A lock having a structure in which a hook member 4 that engages with an inner protruding edge 3 of a frame 2 that receives a cover 1 of an underground structure is pivotally supported on the periphery of the back surface of the cover. The mechanism is a mechanism in which a contact surface 5 is provided outward from the pivot point at the top of the hook member 4, and a lid opening arm 6 with one end facing the small opening 1a of the lid 1 is pivotally supported on the back surface of the lid. , a pressing part 7 is provided at the lower part of one end thereof, which presses the hook member 4 in the direction of separating from the inner protruding edge 3 by contacting the contact surface 5, and further presses the hook member 4 from the back in the locking direction when closing the lid. A locking mechanism for an underground structure characterized in that a pressure member 8 is provided at the other end of the opening arm 6. (2) The inner protruding edge 3 is an inclined surface 3a that slopes downward inward.
A locking mechanism for an underground structure according to claim 1, which is formed to allow the hook member 4 to retreat and pass through when the lid is closed. (3) The locking mechanism for underground structures according to claim 1, wherein the pressure member 8 is a weight that pushes the hook member 4 in the locking direction.
