Claims

[Scope of utility model registration request]

A pipe body is embedded in the U-shaped groove lid and extends from the upper surface to the lower surface; a lower box portion is formed at the lower end of the pipe body and opens to the lower surface of the lid; and a lower box portion is formed at the upper end of the pipe body and the upper surface can be opened and closed. a freely movable upper box part; a strut loosely inserted into the pipe body; a spring provided between the strut and the pipe body to bias the strut upward; and a spring provided at the lower end of the strut; It protrudes from the lower surface of the lid and engages with an engaging part provided on the side of the U-shaped groove to fix the lid, and also rotates with the support column, detaches from the engaging part, rises, and fits into the lower box part, A fixing hook that abuts the upper surface of the lower box portion is provided at the upper end of the column, and is housed in the upper box portion when the fixing hook is engaged, and is raised when the fixing hook is rotated and released. a lifting hook that protrudes above the lid from the upper box portion and can be used to hang the lid by hooking a rope, etc.; A leaf spring piece that comes into contact with the rotating part to stop the rotation of the support and prevents the fixing hook from coming off the engagement part; a cover plate having a push rod hole that allows the plate spring piece to be pushed down through the push rod of the operating jig to rotate the support; and a cover plate that is provided on the pipe body and rotates integrally with the support. A fixture for fixing and lifting a U-shaped groove cover, comprising a stopper pin that comes into contact with the contact portion and prevents the fixing hook from coming off due to rotation in the direction opposite to the direction in which the leaf spring piece of the support abuts.
