[0002] In traditional technology, the door frame is usually manufactured first, then transported to the site and installed on the wall. Then, door frames of different sizes and specifications are manufactured according to the thickness of the wall to cover the installation part of the door frame. Therefore, at least door frames of different sizes and specifications need to be manufactured for walls of different thicknesses, which makes the manufacturing and installation more troublesome. Later, someone studied the adjustable door frame, which divides the door frame into two parts and uses the two parts to detachably adjust the assembled thickness to match the thickness of the corresponding door opening wall.
