Novel aluminum door material with door leaf frame structure

The invention discloses a novel aluminum door material with a door leaf frame structure. The connecting structure comprises a connecting plate and a plate, a mounting groove is formed in the connecting plate; plate for fixing, a first extension wall and a second extension wall are respectively arranged on the opposite sides of the mounting groove; the first extending wall extends into the mountinggroove to form a first protrusion, the second extending wall extends into the mounting groove to form a second protrusion, the bottom of the mounting groove abuts against the corners of the bottom ofthe plate, the first protrusion abuts against the corners of the outer side wall of the plate, and the second protrusion abuts against the inner side wall of the plate. By means of the structure, three abutting points are formed between the plate and the connecting plate, a three-point clamping structure is formed, the three abutting stress directions converge at one point, a three-force-intersection balanced and stable s
