Capacity-expandable cargo turnover box with two kinds of plates capable of being disassembled and restored

Abstract

The invention discloses a capacity-expandable cargo turnover box with two kinds of plates capable of being disassembled and restored. The capacity-expandable cargo turnover box is an express deliveryturnover box which can be disassembled and reassembled. The capacity-expandable cargo turnover box is characterized in that the express delivery turnover box with an internal space capable of be expanded is formed simply by the two kinds of plates, namely, splicing side plates and upper and lower cover plates; and the size relation between each upper and lower cover plate and the structural components of each splicing side plate is as follows: a is equal to b+c+c / 2, wherein a is the side length of each upper and lower cover plate, b is the main body length of each splicing side plate, c is thewidth of each single-slide long and short dual-purpose tenon bar edge, and c / 2 is the depth of each shallow mortise groove, so that the turnover box can be longitudinally and transversely expanded tobe the turnover box having the large internal space. The capacity-expandable cargo turnover box has the advantages that the turnover box can be spliced simply by using the two kinds of plates, the turnover box is very suitable for the express delivery industry to rapidly splice the plates into the turnover box for use and to simply disassemble the turnover box into the two kinds of plates to be recycled, packaging pollution and waste in express delivery are reduced substantially, the turnover box can be expanded horizontally and be expanded in a multilayer manner to form an expandable turnover box with the large internal space and without internal partition plates.

Description

technical field [0001] The invention belongs to a cargo turnover box, in particular to a light object and relatively light cargo turnover box that can be dismantled into a flat panel and quickly clamped to restore the turnover box, that is, a cargo turnover box that is especially suitable for express delivery. Background technique [0002] Light cargo turnover boxes, especially the light cargo turnover boxes used for express delivery, hope to have a turnover box with a small and expandable total volume of goods inside, and no or less shock-absorbing fillers for the goods inside. [0003] In the prior art, the turnover box with a small and expandable total volume of goods contained in it is as follows: [0004] Chinese patent 201120196875.5 Tianjin Lishun Plastic Products Co., Ltd. discloses a "hollow board turnover box" which is divided into a plurality of small box units in a large turnover box. The disadvantages are: First, the large turnover box and the small turnover bo...

AI Technical Summary

Problems solved by technology

The disadvantages are: First, the large turnover box and the small turnover box exist at the same time, and the small turnover box cannot be used alone

The disadvantages are: first, there are too many structural components of the turnover box, and second, the large turnover box combined by multiple turnover boxes only expands the external size, and the space inside the large turnover box is still an independent space for each small turnover box, that is, the combined The resulting large turnover box cannot be loaded with large objects
