Description

Technical Field

[0001] The utility model relates to the field of trolley case devices, in particular to a wear-resistant and scratch-resistant travel trolley case. Background Art

[0002] A trolley case is a box used to carry items when traveling. It is a type of luggage carrier, mainly used to store necessary clothing, personal care products, souvenirs, etc. Early suitcases were made of wood or other heavy materials. With economic development, people's requirements for suitcases have gradually expanded, and the functions of trolley cases have gradually diversified.

[0003] Chinese patent publication number CN209644125U discloses a trolley case comprising a case and a trolley. The trolley has a handle position, a push position, and a pull position, depending on the length of the trolley extending from the case. When in the handle position, the trolley can be used to lift the case. The trolley of the utility model has a handle position, a push position, and a pull position. When in the handle position, the trolley can be used directly as a handle, eliminating the need for a separate luggage handle. This simplifies the design, resulting in a clean and simple appearance and easy carrying.

[0004] The above application uses a trolley-type suitcase, in which the vertical rods of the trolley are arranged on both sides of the box frame. At the same time, the trolley has two functions: pushing and pulling. The box is prone to collision with obstacles during the pushing process, which can easily cause scratches during the collision, thereby damaging the box shell. At the same time, the closed interior of the box is prone to odor and bacteria, etc. Therefore, the trolley case has deficiencies in external protection and breathability. Utility Model Content
