Rigid fastening mechanism for mobile transport vehicle frame

The invention relates to a rigid fixing mechanism. The rigid fixing mechanism is arranged on an angle part of a movable vehicle transportation frame and is in rigidly fixed with a container. The rigid fixing mechanism comprises an upright post, a first inclined strut and a second inclined strut, wherein the upright post is fixed on the position of the sidewall of the container corresponding to the angle part of the movable vehicle transportation frame, the upright post is provided with a plurality of fixed holes longitudinally distributed at interval; the first end part of the first inclined strut is connected with one of the fixed holes through a first connecting piece, and the second end part of the first inclined strut is connected with the angle part of the movable vehicle transportation frame through a second connecting piece; the first end part of the second inclined strut is connected with another of the fixed holes through a third connecting piece, the second end part of the second inclined strut is rotatablely connected with the second end part of the first inclined strut through a fourth connecting piece. The rigid fixing mechanism is in rigid connection with the upright post and the vehicle transportation frame through the first inclined strut, and the movable vehicle transportation frame and the container can be rigidly fixed, thereby avoiding automobile damage caused by shaking in the transportation process.
