What does the special-shaped frame of the suitcase mean?

The suitcase special-shaped frame is an irregular suitcase outer frame.

A suitcase refers to a suitcase with a pull rod and rollers. Because of its convenience, it is widely used to match clothes when traveling and going out. At the same time, the suitcase also has a pull rod for the box, which can be divided into single-tube pull rod and double-tube pull rod, and the tube of the pull rod can also be divided into square tube and round tube to facilitate dragging when walking, greatly reducing the burden.

The suitcase can be carried or towed. The wheels of the suitcase we usually use are basically located at the bottom of the suitcase. Modern people have designed a new type of suitcase, which has a cylindrical shape and the wheels are wrapped around the outside of the suitcase. This kind of roller design enables this suitcase to better adapt to different terrains. For example, it can easily go up and down stairs by pulling the suitcase directly.

Luggage shopping guide

The common sense of buying luggage brands also includes materials. Luggage cases can be divided into soft cases and hard cases according to different materials. Hard cases include ABS (Styrene Polymer) cases and PP cases (injection molding), while soft cases generally refer to EVA cases.

ABS boxes are moisture-proof and pressure-resistant, so even in rainy and snowy weather, there is no need to worry that the items in the boxes will get wet. Moreover, due to the materials used, the box itself is not very flexible, and it is suitable for storing cameras and other valuables. In the case of external impact, the contents in the box will not be easily damaged. Its lock is a coded lock with a side lock.

EVA soft package box is different, it is characterized by light weight, that is, the box itself is relatively light, and the box has certain flexibility. Compared with ABS and PP boxes of the same specification, it can hold more articles, so its biggest advantage is large capacity, portability and convenience. Its lock is a password lock without side lock, and some models even have no password lock, so users need to add a lock.
