Description

Retractable hard box structure

The present invention relates to a storage box structure, and more particularly to a retractable rigid box structure which is easy to retract and reduce the occupied storage space.

According to the conventional hard box, since it has sufficient structural strength, it has a higher protective effect than the soft bag body, and is advantageous for carrying out the movement and stacking of the box, such as a trunk or a bicycle special box, etc. The hard case also has obvious disadvantages when it is stored. The main reason is that when the hard case is not in use, the fixed volume of the case is quite space occupied during storage, and it is not placed too much in the home under normal use. The spare box will not only cause users to be troubled in storage, but also cause the sales volume of the box to be greatly affected. Some operators have improved the box for the problem that the hard box is too space-consuming. The box is disassembled into several components for stacking and storage. Although the volume of the method can be effectively reduced, the complexity of disassembly and assembly is too high, and it is disassembled once for a long time, so that the user cannot quickly disassemble, It can't even be assembled correctly. In addition, some manufacturers use rubber or cloth to connect the box to bend the box, so that the box can be folded and flattened. The joint of the box cannot provide sufficient structural strength, which causes the box to have the disadvantage of insufficient compressive strength, and it is also very easy to be damaged by the joint.
