Dismountable-mountable and capacity-increasable jointed board type turnover box provided with shock mitigation system

Abstract

The invention relates to a dismountable-mountable and capacity-increasable jointed board type turnover box provided with a shock mitigation system. The dismountable-mountable and capacity-increasablejointed board type turnover box provided with the shock mitigation system is an express turnover box which can be dismounted, mounted, and internally provided with an airbag system. According to the turnover box, the internal-capacity-increasable express turnover box provided with the jointed airbag system is formed only by two kinds of plates including jointed side plates and upper and lower cover plates, wherein combined airbags are arranged in bodies of the jointed side plates and the upper and lower cover plates. Single slide long and short dual-purpose tenon strip sides, single slide double-mortise groove side long and short dual-purpose mortise and tenon joint structures, and various structural components of the jointed side plates meet the formula that a=b+c+c/2, so that the turnover box can be longitudinally and transversely expanded into a large-internal-capacity expansible turnover box. The turnover box has the advantages that only the two kinds of plates can be easily and conveniently spliced to form the turnover box and are quite suitable for being quickly spliced into the turnover box used in the express industry, the turnover box can be simply disassembled into the two kinds of plates for recycling, and express packaging pollution and waste are greatly reduced; and the turnover box can be expanded in a plane mode and in a multi-layer mode so as to obtain the large-internal-capacity expansible turnover box free of internal partition plates, and the jointed airbag system in the turnover box can protect internal cargos in a shock mitigation mode even if filler isreduced or not used.

Description

technical field [0001] The invention belongs to the express delivery turnover box, especially the light object and lighter express delivery turnover box which can be dismantled into a flat panel and can be quickly clipped and restored, and is equipped with a combined airbag for filling, that is, it is especially suitable for the express delivery turnover box box. Background technique [0002] Light express turnover boxes, especially the light express 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 a...

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

[0010] The disadvantages of the above three shock-absorbing airbag patents are: the turnover box cannot be disassembled and it is not convenient to recycle the turnover box material by reducing the volume; the turnover box cannot be spliced ​​to expand or reduce the volume, but cannot reduce or increase the gap between the space in the turnover box and the objects; Each airbag can be inflated independently, which is inconvenient to use in the emerging express delivery industry. Each airbag is independent so that the contents of the turnover box cannot be centered, and it is easy to damage the contents during transportation.

[0011] The reason why the traditional mortise and tenon structure cannot be used as a turnover box for inner space expansion: the trad
