The invention relates to a self-locking door window frame which is characterized in that a door window frame body (1) is mounted in a wall hole in a wall body (4) and consists of corresponding front and rear sheets consisting of vertical columns (3) and head door sills; the vertical columns (3) of the door window frame body (1) are connected with rod bodies (10); trapezoid structures (9) with fastening holes (11) are arranged at the front ends of the rod bodies (10); bolts (6) are arranged in the trapezoid structures (9) at the front ends of the rod bodies (10); in a process of tightening the bolts (6) and nuts (7), the slopes (12), at the front ends of the rod bodies (10), of the trapezoid structures (9) slide relatively, and the slopes (12) at the front ends of the rod bodies (10) slide relatively to strain the corresponding front and rear sheets of the door window frame body (1). The self-locking door window frame is very easy and convenient to mount and dismount; furthermore, the door frame body can be firmly clung to the wall surface.
