The invention discloses a hidden type door within a door and relates to a security door. At present, most small door frames are inlaid in main door leaf rear boards after being subjected to edge folding, forming and splicing, the small door frames protrude much higher than main door leaf panels, and therefore appearance attractiveness is affected. The hidden type door within the door is characterized in that a small door opening is formed in the middle of a main door leaf, a rear door sheet is provided with a concave-convex-shaped pattern, a rear panel at the edge of the small door opening is concaved forwards to form a door frame groove, and the door frame groove is matched with the outer edge of a small door frame; supporting plates located between a front main door sheet and a rear main door sheet are arranged on the periphery of the small door opening; a back-flap hinge comprises a hinge body, a door leaf hinge fixing plate and a door frame hinge fixing plate; the hinge body comprises a door leaf connecting piece and a door frame connecting piece; the door leaf connecting piece is connected to the small door leaf through the door leaf hinge fixing plate, and the door frame connecting piece is connected to the small door frame through the door frame hinge fixing plate. According to the technical scheme, the squish type design is adopted, the small door frame can be exactly inlaid in the pattern groove in the rear door sheet and is matched with a reversely convex style of a main door leaf rear board, in this way, the small door frame will not be higher than the rear main door leaf rear board, and therefore integrity is high.
