Cornerite Device for Suitcase and Suitcase

Abstract

A suitcase cornerite device and a suitcase belong to the field of cases and bags. The suitcase cornerite device includes: first cornerites configured to wrap top corners of a case body of a suitcase and second cornerites configured to wrap bottom corners of the case body, with side edges of the first cornerites and/or the second cornerites abutting against respective opening-closing frames of the suitcase. With this structural design, one side edges of the first cornerite and the second cornerite may abut against respective opening-closing frames of the case body, such that the case body can obtain, when withstanding a compressive force, an additional supporting force provided by the cornerite device. The suitcase provided by the application includes the aforementioned suitcase cornerite device, and thus has good compression resistance, ruggedness and durability; furthermore, the large-area cornerite contributes to improve the friction resistance of the case body.
