Embodiment Construction

[0012] The structure of the present invention is composed of a box body 2 and a tie rod 1 connected thereto, a cross-shaped ladder wheel 3 and a load-bearing roller 4. The box body 2 is made of cloth or leather; the pull rod 1 is made of aluminum alloy; the cross-shaped ladder wheel 3 and the load-bearing roller 4 are drawn from the alloy. The cross-shaped ladder wheel 3 and the load-bearing roller 4 are consolidated with screws and a box.

[0013] At present, the national standard stipulates: the stair step height S 1 150 mm, step width S 2 The angle between the line connecting the end of the ladder and the horizontal ground is 27°, and when the human body is pulling the suitcase, the inclination angle between the suitcase and the ground is generally greater than 45°. The distance L between the two axles is 110 mm: the prerequisite is that the diameter of the load-bearing roller 120 mm, the diameter of the outer circumference of the cross-shaped ladder wheel 90 mm, the ...
