Lightweight armored vehicle inspection cabin cover plate

The utility model discloses a lightweight armored vehicle inspection cabin cover plate which comprises a cover plate frame, a cover plate skin and a sealing rubber strip. The cover plate frame is of a square frame structure formed by welding steel bars. The cover plate skin is installed on the cover plate frame through rivets and covers the whole cover plate frame. And a sealing rubber strip is adhered to the inner edge of the cover plate frame. The cover plate frame is simple in structure, the cover plate frame is formed by assembling and welding Z-shaped long rods and short rods which are formed by bending 3 mm aluminum alloy plates, and the rigidity and strength of the cover plate frame can be ensured through the profiling structure. Bending, welding and riveting processes are reasonably combined and applied, and the self weight of the cover plate is effectively reduced. Compared with a homogeneous plate thickness cover plate with the same size, the weight reduction effect of the cover plate is obvious, an
