Description

A carbon fiber box

Technical field

The utility model relates to the technical field of luggage and bags, in particular to a carbon fiber box body.

Background technique

Trolley cases have long become essential luggage supplies for people to go out for short-term or long-term trips. Due to the difference in size and capacity, the trolley cases can hold different items in number or volume. The existing trolley box generally includes two box bodies, one of which is provided with a pull rod, one side of the two box bodies is connected by a zipper, and the two boxes can be closed by a zipper or a lock. When you need to take out the items in the trolley box, you need to open the zipper between the two boxes, and then rotate the two boxes to open. However, the trolley case of this structure has certain problems. For example: 1. It is more troublesome to produce because two large boxes are to be produced; 2. If the inside of the trolley case is filled with items, two more When the box body is opened, it is easy to cause the items in the trolley box to fall, which not only wastes the user’s time to pick up these items, but also easily causes dirt to adhere to these items, causing trouble for the user. Therefore, in order to prevent the items in the box from falling, the user will appropriately reduce the number of items placed, which wastes a certain amount of space in the box. Third, the two boxes of the trolley box on the market now mostly use the Made of PVC material, the box made of this kind of material still has shortcomings in the problems of compression resistance, earthquake resistance, corrosion resistance and weight; fourth, it is not beautiful enough.
