[0004] The utility model solves the above technical problems with a technical solution: a deck opening protection device is provided, including a U-shaped slot, a fastener and a grille plate, a connecting portion is provided on one side of the closed end of the U-shaped slot, a hole slot passing through both ends of the connecting portion is provided inside the connecting portion, a plurality of connecting rods are provided on one side of the grille plate, each connecting rod is provided with a through hole with the same size as the hole slot, the connecting rod on one side of the grille plate is correspondingly installed on the open slot provided on the U-shaped slot connecting portion, and an open pin passes through the hole slot and the through hole, and cooperates with the pin to make the grille plate rotatably connected to the U-shaped slot, a threaded hole is provided on one side of the U-shaped slot, and a fastening bolt is provided in the threaded hole.

[0005] The technical solution further defined in the utility model is:

[0006] Preferably, a rotating handle is fixedly provided on the top of the fastening bolt to facilitate bolt fixing.

[0007] Preferably, a pressure block threadably connected to the bottom of the fastening bolt is provided.

[0008] Preferably, rubber strips are provided on the bottom of the pressing block and on the inner wall of the U-shaped slot on the opposite side thereof.

[0009] Preferably, the threaded hole and the connecting portion are on the same side.

[0010] The beneficial effects of the utility model are as follows: the utility model has a simple structure and is reusable. The corresponding grille can be replaced according to the size of the deck opening. The grille is hinged to the U-shaped slot through a cotter pin and is fixed to the opening by rotating the fastening bolt to prevent people or objects from falling, thereby meeting the protection requirements of the construction site. Rubber strips are provided on the bottom of the pressing block and on the inner wall of the U-shaped slot on the opposite side thereof, which can be used on stainless steel surfaces or painted surfaces to ensure stable and reliable connection.
