Furthermore, one side of the lower guide connecting block, which is close to the outer side of the base plate, is an inclined guide surface.
When the device is used, the mounting base is mounted on a trailer through the bolt and the threaded mounting hole in the base plate, a worker holds the handle to enable the cylindrical long rod to sequentially penetrate through the round hole in the upper connecting block, the upper connecting ring of the material frame and the round hole in the lower guide connecting block, the opening is aligned with the locking nut, and the cylindrical long rod is rotated after the circular truncated cone is propped against the locking disc, so that the locking bolt is clamped on the outer side of the locking disc to form effective locking. When the material rack does not need to be connected with a trailer, a worker rotates the cylindrical long rod through the handle, so that the opening can pass through the locking bolt to form Z-direction up-and-down motion, the cylindrical long rod is pulled out, and then the movable material rack is taken out.
The invention has the beneficial effects that: according to the invention, the cylindrical movable rod is used for performing upward and downward operation and rotation operation in the Z direction, so that the effective locking connection between the material rack and the trailer power source is realized. According to the invention, through the locking structure, efficient, accurate and quick operation of staff is effectively realized, the transportation process is stable and reliable, the device is suitable for various different occasions and different operation environments, the transportation safety is efficiently ensured, the labor intensity of the staff is reduced, and the production operation efficiency is improved.
