Claims

[Claims for Utility Model Registration] A lid, a frame that supports the lid, a catch protruding from the inside of the frame and having a locking hole, and a rod-shaped seat whose upper part is the edge of the lid. The main body is vertically movable and rotatably inserted into the locking hole of the catch, and the lower part consists of a connecting rod that is in collision engagement with the catch. A lid frame structure for an underground structure that can be opened by horizontal rotation or vertical reversal, wherein the lid body has a pair of plate-like ribs extending downward from the lower surface thereof and facing each other, and opposing surfaces of these ribs. a pair of protrusions protruding oppositely from the connecting rod; on the other hand, the connecting rod has a pair of sliding surfaces on its upper portion that slide on opposing surfaces of the ribs, and each of the sliding surfaces A substantially horizontal groove and an inclined groove that slopes downward and opens from the horizontal groove are formed, and the pair of protrusions are removably engaged with each horizontal groove via each inclined groove, thereby connecting the connecting rod. Lid frame structure for underground structures, which is pivoted to the lid body.
