The top and the bottom of the window frame are both fixedly connected with two sliding grooves. Edges on the two sides of the window frame are fixedly connected with sealing rubber strips. Sliding blocks are arranged at the bottoms of the movable window bodies and connected in the corresponding sliding grooves in an embedded mode. Five lock holes which are distributed at equal intervals are formed in each sliding groove in the bottom of the window frame. The bottom of each movable window body is provided with a lock head. The contact face between each lock head and the corresponding sliding groove is provided with a spring bolt. A lock cylinder is arranged on the front face of each lock head. When the movable window bodies slide in the corresponding sliding grooves, the movable window bodies are locked automatically when the spring bolt of each lock head coincides with the position of any lock hole. The lock cylinders are provided with keys matched with the lock cylinders. Self-locking can be relieved when a user inserts the matched keys into the lock cylinders and rotates the keys clockwise by 90 degrees. By the adoption of the self-locking type antitheft window provided by the invention, antitheft can be achieved effectively.
