Trolley Case 08

The trolley case is also divided into single-tube pull rod and double-tube pull rod because the box is equipped with a pull rod, and the pull rod tube is also divided into square tube and round tube, so as to facilitate dragging when walking and greatly reduce the burden. luggage case can be carried or dragged. The wheels of luggage case we usually use are basically located at the bottom of the box. Modern people have designed a new type of luggage case. The box is designed into a cylindrical shape, and the wheels are completely outsourced on the outside of the box. Such roller design makes this luggage case better adapt to different terrains, such as pulling the box directly can easily go up and down stairs. Of course, the tie rod should be built-in, and the material must be steel (external tie rods and wheels must not adapt to the brutal loading and unloading of various flights nowadays)! The box body should have a steel frame, the fabric is preferably rainproof, and the granularity of the material is better, because it is more wear-resistant, and the wheels must be built-in, needless to say.
