Hard suitcase and manufacturing method thereof

Abstract

A hard suitcase comprises a frame body and case cover, wherein the case cover comprises a flat bottom surface and four bending surfaces; the flat bottom surface and the bending surfaces are integrally formed and the four bending surfaces are in the same plane with the flat bottom surface before the bending surfaces are bent; the flat bottom surface is the bottom surface of the case cover; after being bent, the four bending surfaces are matched with the frame body to form a vertical plane at the height of the case cover. The manufacturing method of the hard suitcase comprises the manufacture of the frame body and the case cover; the manufacturing processes of the case cover comprises the following steps: firstly, a flat sheet material is cut into a flat bottom surface and four bending surfaces; then the four bending surfaces are bent into four vertical planes at the height of the case cover; finally, the frame body and the case cover are assembled. The hard suitcase and the manufacturing method thereof have the characteristics that the waste is less, the procedures are simple and required devices are simple.

Description

technical field [0001] The invention relates to a travel hard case and a manufacturing method thereof. Background technique [0002] The existing travel hard case includes a frame body and a case cover. The case cover of hard plastic material includes a flat bottom surface and a height elevation, wherein the height elevation is formed by blister molding, and the height elevation after blister molding still needs to be processed. The use standard can only be achieved by flat cutting and removing excess parts, and the cut parts can only be recycled as waste, resulting in a lot of waste, and blister molding requires high thermal processing costs; the formed box cover occupies an The space is large, even if multiple box covers are stacked together like stacking bowls, there is still a waste of space on the facade of the height of the box cover, which will cause a certain waste of transportation costs. When installing the existing travel hard boxes, The aluminum frame and the pl...

[0002] The existing travel hard case includes a frame body and a case cover. The case cover of hard plastic material includes a flat bottom surface and a height elevation, wherein the height elevation is formed by blister molding, and the height elevation after blister molding still needs to be processed. The use standard can only be achieved by flat cutting and removing excess parts, and the cut parts can only be recycled as waste, resulting in a lot of waste, and blister molding requires high thermal processing costs; the formed box cover occupies an The space is large, even if multiple box covers are stacked together like stacking bowls, there is still a waste of space on the facade of the height of the box cover, which will cause a certain waste of transportation costs. When installing the existing travel hard boxes, The aluminum frame and the plastic box cover are fixed with nails. In this production method, the aluminum frame and the box cover need special tools to fix the nails. Ordinary consumers or dealers cannot install them by themselves. The box cover is installed well, so that more space is wasted in the transportation process, which increases the transportation cost
