The invention relates to an antitheft door, in particular to a spliced hidden type door within a door. At present, for a door within a door structure with a frame, imperfect matching between the door within the door and a main door leaf can be caused easily, screws or rivets are prone to loosening and even falling off, a small door leaf is made to shake, and use is influenced. The spliced hidden type door within the door is characterized in that a hole is formed in the middle of a rear board of the main door leaf, the four edges of the hole are bent forwards to form small door frame edges, and the small door frame edges are spliced to form a small door frame; a back-flap hinge comprises a hinge, a door leaf hinge fixing plate and a door frame hinge fixing plate, and the hinge 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 small door frame is formed by bending the main door leaf plate, the integrality is good, the structure is firm, the small door frame is matched with the small door leaf, and the spliced hidden type door within the door is reliable in use.
