description The utility model discloses a simple combined door frame comprising a main door frame (1) and an auxiliary door frame (2). The main door frame (1) and the auxiliary door frame (2) are integrally connected by tongue and groove joint. A connection portion of the main door frame (1) comprises a surface tongue, a middle groove and a bottom tongue. A connection portion of the auxiliary door frame (2) comprises an upper tongue and a lower groove. The upper tongue of the auxiliary door frame (2) is inserted into the middle groove of the main door frame (1) for connection. A stabilizing plate (3) is disposed in a gap between the bottom tongue of the main door frame (1) and the lower groove of the auxiliary door frame (2). The simple combined door frame is widely adaptable to field size deviations, so that the field for industrial production and productization assembly of door frames is guaranteed. The workload in steps, such as early size statistics, field size check of goods and resizing during construction, is grea
