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

Abstract

The cargo turnover box with two kinds of boards that can be dismantled and restored and whose capacity can be expanded is a turnover box for express delivery that can be dismantled and reloaded. The turnover box only uses splicing side panels and upper and lower cover panels to form an expandable inner empty capacity express turnover box; the splicing side panel has a single-sliding long and short dual-purpose mortise and a single-sliding double-mortise edge. Long and short dual-purpose mortise and tenon The structure and the dimensional relationship of each structural part are a=b+c+c/2, etc., so that the turnover box has an expanded turnover box that can be expanded into a large inner space longitudinally and laterally. Advantages: only two kinds of boards can be spliced ​​into turnover boxes in a simple and convenient manner, which is very suitable for the express industry to quickly splice into turnover boxes and simply divide into two types of boards for recycling, which greatly reduces the pollution and waste of express packaging. The turnover boxes can be expanded and multi-dimensional The layer is expanded into a large inner space expansion turnover box without inner partitions.

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...
