Technical Field

[0001] The utility model relates to the technical field of luggage, in particular to a reinforcing frame and a suitcase. Background Art

[0002] Suitcases are essential items for people to travel. At present, suitcases on the market can generally be divided into two categories: zipper suitcases and hard-frame suitcases. A zipper suitcase means that zippers are provided at the edges of the front and rear shells of the suitcase, and then the front and rear shells are connected by the zippers; a hard-frame suitcase means that a circle of hard frames made of metal or non-metal materials are provided at the edges of the front and rear shells of the suitcase, and then the front and rear shells are snap-connected through the hard frames. There is a large gap in the manufacturing processes between hard-frame suitcases and zipper suitcases. In actual processing, zipper suitcases more often adopt tailoring techniques, while hard-frame suitcases, due to their high hardness, usually adopt riveting. Therefore, hard-frame suitcases far exceed zipper suitcases in terms of quality and impact resistance. However, precisely because hard-frame suitcases are fixed by riveting, the processing difficulty is high and the process is relatively complex. Therefore, the cost of hard-frame suitcases is usually much higher than that of zipper suitcases.

[0003] The technical problem to be solved by this application is: how to solve the problems of complex processing and high production cost of existing hard-frame suitcases. Content of the Utility Model
