[0009] Preferably, the side of the angle steel towards the hinged end of the grating is provided with a baffle.

[0010] Compared with the prior art, the present application has the following advantages:

[0011] 1. Without the need for anti-piracy, the first and second ear plates are fixed by bolt assemblies, and the grating is fixed to the bottom surface of the second inclined ladder, thereby facilitating the passage of crew; in the case of anti-piracy, the first and third ear plates are fixed by bolt assemblies, and the grating is fixed and blocked at the stair opening, and the first sheath hinders the unlocking of pirates, thereby improving the safety of protection.

[0012] 2. The first sheath hides a retaining ring, which can only be removed with special tools, increasing the difficulty of unlocking the grating and further improving the safety of protection. BRIEF DESCRIPTION OF DRAWINGS
