The invention discloses an adjustable drawing board frame for art teaching. The adjustable drawing board frame comprises a triangular plate, short rods are in penetrating connection with the inner side of the triangular plate at equal intervals, the outer sides of the short rods are sleeved with long rods, and the outer sides of the long rods are sleeved with stand columns. Clamping holes are formed in the top of the triangular plate at equal intervals, the inner sides of the clamping holes are in movable clamping connection with connecting rods, the tops of the connecting rods are fixedly connected with a wide plate, and a groove is formed in the top of the wide plate. A cross rod is in penetrating connection with the inner side of the groove, the outer side of the cross rod is sleeved with a drawing board, sliding grooves are formed in the two sides of the drawing board, and the sides, close to the drawing board, of connecting plates are fixedly connected with locating strips. According to the adjustable drawing board frame, the triangular plate, the clamping holes, the connecting rods and the wide plate are used in cooperation, so that the problem that a drawing board frame is inconvenient to demount, mount and carry is solved; the sliding grooves, damping springs, a sliding block, the connecting plates, the locating strips and extruding pads 21 are used in cooperation, so that the problem that a drawing is hard to fix during drawing is solved.
