The invention relates to a doorframe. The doorframe comprises a front frame and a rear frame which are connected through a width adjusting mechanism. The width adjusting mechanism comprises a width adjusting board A, a width adjusting board B and bolts. The two ends of the width adjusting mechanism are respectively fixed to a fixing board on the front frame and a fixing board on the rear frame. An installation process of the doorframe comprises following steps: sandwiching a wall between the front frame and the rear frame; adjusting the distance between the front frame and the rear frame according to the thickness of the wall; fastening the bolts; boring holes in the wall; inserting expansion screws into the holes; fastening the expansion screws so as to fix the doorframe to the wall; and finally mounting a closure board on the doorframe. The closure board comprises a clamping strip A, a clamping strip B and a panel, and the clamping strip A and the clamping strip B on the closure board are respectively clamped on the front frame and the rear frame. According to the invention, the front frame and the rear frame of the doorframe are connected through the width adjusting mechanism, so that the width of the doorframe can be adjusted, and the doorframe is suitable for walls having different thickness.
