The invention provides a pedal angle adjustable-type ladder, and relates to the field of airplane structure design. The pedal angle adjustable-type ladder comprises two boundary beams and pedals; the pedals are arranged between the two boundary beams at equal spacing, and the ends, near the same long side, of two broad sides of each pedal are fixed to the boundary beams through boundary beam and pedal hinge pins; the other ends of the two broad sides of each of the pedals in a parallel state are respectively connected by connecting rods and pedal connecting hinge pins; regulating connecting rod fixing holes are formed in the boundary beams and near the top ends of the boundary beams; regulating connecting rods respectively penetrate through the regulating connecting rod fixing holes, and one end of each of the regulating connecting rod and the corresponding connecting rod are fixedly connected with the pedal at the top end of the ladder by adopting the same pedal connecting hinge pin. The pedal angle adjustable-type ladder provided by the invention is simple and reasonable in structure; by arranging the connecting rods and the regulating connecting rods, the angles of the pedals relative to the boundary beams can be adjusted, so that personnel can conveniently climb up and down the ladder; the pedal angle adjustable-type ladder is convenient to disassemble, high in stability, safe and reliable.
