Door plate windproof transverse rod

The invention relates to a door plate windproof transverse rod. The door plate windproof transverse rod comprises a transverse rod body, trays used for placing the transverse rod body, tray brackets used for supporting the trays, wall-penetrating iron rods and buckle parts. Antiskid patterns are arranged on the surfaces, used for placing the transverse rod body, of the trays. The tray brackets aretriangular frames and are connected with a wall and the trays correspondingly, and the tray brackets are made of rust-proof materials. Rust-proof materials are arranged on the surfaces of the wall-penetrating iron rods, one ends of the wall-penetrating iron rods are fixed to the transverse rod body in a welded mode, the other ends of the wall-penetrating iron rods penetrate through penetrating holes in a wall body, and clamping connection holes are formed in the other ends of the wall-penetrating iron rods. The buckle parts and the clamping connection holes are detachably connected so that the wall-penetrating iron r
