Stretchable turnover box

Abstract

The invention relates to a stretchable turnover box. The turnover box is formed by three main body parts which respectively comprise a rectangular bottom plate, four stretchable steel pipes and a pair of cover plates. When the stretchable turnover box is used, a steel rod can be pulled out from a steel rod storage groove, canvas is stretched to a needed length, the steel rod can be pressed into a steel rod fixing groove of the stretchable steel pipes, then the cover plates are covered, and plugs between the cover plates and the stretchable steel pipes are inserted, thereby finishing boxing. When a lateral box body is not used, the stretchable turnover box can be retracted back to a steel rod cavity of the bottom plate, so that a storage space is saved, and the stretchable turnover box is simple and feasible to assemble when being used. The stretchable turnover box disclosed by the invention is adjustable in height and is easy to store articles with a fixed shape and different heights.

Description

Technical field [0001] The invention relates to a stretchable turnover box, especially a turnover box suitable for the circulation of goods with regular shapes. Background technique [0002] At present, well-known logistics turnover boxes such as "BB-T0043-2007 Plastic Logistics Turnover Box" are introduced in general, folding, and oblique insertion types. Among them, the general-purpose box is in the shape of a cuboid or a cube, and can be stacked to a certain number of layers. This kind of turnover box has a simple structure, but no matter whether it is loaded or not, it takes up the same storage space and wastes a lot of empty boxes. The folding type is developed on the basis of the universal type. Compared with the universal type, its advantage is that the box can be folded as a whole, and it can be opened when loading, and folded when not loading to save space; the diagonal insertion type is also It is expanded on the basis of the universal type, and its inclined or stepped...

Problems solved by technology

[0003] The above three types of boxes all have a problem, that is, the storage capacity and the three-dimensional size of the internal storage space of a certain size box are fixed. Once the length of the goods exceeds the storage length, the goods cannot be loaded. in the box

For example, it is difficult to obtain a suitable turnover box for storage of rod-shaped goods exceeding a certain length
