Description

Technical Field

[0001] This utility model relates to the field of luggage, specifically to a suitcase with a narrow aluminum frame. Background Technology

[0002] Heavy-duty or high-end suitcases mostly use two interlocking rigid aluminum frames to support the openings of the upper and lower shells and facilitate opening and closing. However, currently, most suitcases with aluminum frames either have the frames covering the outside of the openings of the upper and lower shells or the openings of the upper and lower shells inserted into a groove in the middle of the aluminum frame before hinged or riveted. Because the main body of the metal aluminum frame is exposed outside the openings of the upper and lower shells, the overall appearance of the suitcase looks bulky and affects its aesthetics. In addition, suitcases usually need to have a removable lining, and the lining zipper used is mostly riveted when installed on the aluminum frame, which is inconvenient and affects the efficiency of the installation. Therefore, there is a demand for a suitcase with a narrow-sided aluminum frame, where only the narrow side of the aluminum frame is exposed after the upper and lower shells are installed, and the lining zipper can be movably connected to the inside of the aluminum frame, thereby enhancing the aesthetics of the suitcase and improving the efficiency of the installation process. In view of this, this project was developed. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses a suitcase with a narrow-sided aluminum frame, including an upper shell, a lower shell, an upper frame, a lower frame, a zipper, and a lining. The upper frame and the lower frame are respectively provided with an upper shell clamping opening and a lower shell clamping opening on their outer sides. The upper shell clamping opening and the lower shell clamping opening are respectively J-shaped and inverted J-shaped grooves, and the lower side of the outer side of the groove is a narrow edge. The upper frame and the lower frame are each provided with a zipper clamping opening for installing the zipper. This invention places hinged upper and lower frames between an upper and lower case shell. Using upper and lower case clamping openings with narrow and wide sides on the outer sides of the upper and lower frames, the openings of the upper and lower case shells are respectively embedded and glued into these clamping openings. This allows only the narrow sides of the upper and lower frames to be exposed while concealing the wide sides, resulting in a slimmer appearance at the opening and enhancing the aesthetics of the suitcase. Zipper clamping openings on the inner sides of the upper and lower frames, along with square cavities at their ends, allow the zipper to be movably connected to the aluminum profile upper and lower frames via a limiting rod that engages with the square cavity at the end of the zipper clamping opening. This improves the efficiency of suitcase assembly.
