   Among the many accessories in the trolley case, the wheels of the trolley case can be said to be the most important. Once broken, it is not only disappointing to carry a large box of luggage. If the number of days is longer, it is possible to carry it to the disabled.     Â
   When picking, the most basic requirement is of course "solid" and not too small, otherwise it will hit the pit road and it is easy to get stuck or get stuck. In addition, it is better to choose to rub against the ground without noise (low coefficient of friction). For example, multi-row wheels and rubber wheels are easier to use. Again, if there is a 360- degree swivel design that can be moved sideways, or a flexible function that can flex and climb stairs, it's even more convenient.
   In addition, it is also important that the weight of the trolley case and the speed of the wheels are not matched. Because according to the measurement, the individual's one-handed drag is best controlled at a weight of about 15 to 25 kilograms, so the two-wheel design of Yangchun generally has no problem if the baggage is light, but when the baggage exceeds 25 kilograms, it takes only two rounds to pull. It will take more than twice the effort to pull four rounds. When the capacity of the soft box is increased, in addition to the four wheels that can rotate 360 degrees, the design of the telescopic extension wheel must be appropriately increased to support the weight of the chassis. Also note that although the more wheels, the more effort, but it will also increase the weight of the suitcase, so the more the better the wheels.

The pull rod is also a very important accessory for the “bargaining†of the trolley suitcase. In the selection, in addition to pay attention to the rod material is not strong enough, one-handed operation is not convenient, but also choose a multi-stage scalable design, in order to adjust the most suitable height, comfortable and labor-saving. If a low-priced trolley case is presented as an event, the drawbars are mostly fixed and the material grade is not sufficient. Once an external force collides with them, it is easy to get rid of the deformation, which will increase the inconvenience and burden on the journey.
