Abstract

The invention belongs to the field of doors and particularly relates to a durable door frame with less breakage possibility. The door frame comprises a door plate baffle step and a door frame base which are integrally molded, wherein the door plate baffle step is internally provided with support strips; the door frame base is internally provided with a metal frame adhered to the inner wall of the door frame base; the metal frame is filled with a fireproof material; the support strips are arranged in a direction parallel to the door frame base; the sides, which are back onto the door plate baffle step, of the metal frame and the door frame base are provided with openings; the opening of the metal frame is provided with an extension edge inserted into a wall. The support strips, the metal frame and the fireproof material can be used for greatly improving the impact resistance of the door frame and also improving the flame resistance of the door frame; due to the extension edge design, the door frame can be connected with the wall more firmly. The door frame is high in strength, durable, less in breakage possibility and long in service life.
