A kind of customization type perforated plate Turnover Box
Technical field
The present invention relates to Turnover Box, particularly relate to a kind of customization type perforated plate Turnover Box.
Background technology
Along with china socialism's market economy system foundation, the quickening of world economic integration process and the develop rapidly of science and technology, material flow industry is as improving the market competitiveness and promote the important means of enterprise core competence. Turnover Box, as the carrier of logistics, is widely used for a long time always. Traditional common Turnover Box is fixing closed-in construction, takies space big during its sky case, and the cost of empty case transport and storage is all higher, and therefore, people consider the various folding Turnover Box of design.
On existing market, there is the large-scale turnover box honeycomb hoarding box that a kind of bearing better can fold again. Existing honeycomb hoarding box structure can see the German patent document of DE29503254U1. Disclosing a kind of hoarding box in this patent, comprise at the bottom of case lid, coaming plate and case, its coaming plate adopts perforated plate and can fold, and is that integrated die-casting is shaping at the bottom of case lid and case. This kind of chest bearing is pretty good, but has the following disadvantages: shaping owing to being integrated die casting at the bottom of case lid and case, it is necessary to die sinking is produced, and mould is expensive, is only suitable for producing in enormous quantities, is not suitable for nonstandard part small serial production.
Summary of the invention
It is an object of the present invention to provide a kind of customization type perforated plate Turnover Box, under the prerequisite ensureing casing bearing by case at the bottom of and case lid change splicing structure into, to be applicable to nonstandard part small serial production.
For achieving the above object, the technical solution used in the present invention is: a kind of customization type perforated plate Turnover Box, the coaming plate comprising at the bottom of case lid, case and being arranged between at the bottom of case lid and case;
Described case lid comprises the cover plate of a rectangle, and the four edges of this cover plate respectively establishes a case lid edge strip along upper, and case lid edge strip is angle steel, and its horizontal wall is mutually stacked with the end face of cover plate, and its vertical walls is down; Also establishing cornerite on the corner of cover plate, cornerite is placed on two adjacent case lid edge strips and is fixedly connected with;
Comprising the base plate of a rectangle at the bottom of described case, the four edges of this base plate respectively establishes one case base bar along upper, and case base bar is also angle steel, and its horizontal wall is mutually stacked with the bottom surface of base plate, and its vertical walls is upward;Also being provided with footing on the corner of base plate, footing is placed on two casees adjacent base bars and is fixedly connected with;
Described coaming plate is made up of parallel relative two retaining plate portions and parallel two folding plate portions relatively, the first folding line establishing hot pressing and become in the nook that connects in its retaining plate portion with folding plate portion on described coaming plate, the 2nd folding line that the middle part in two folding plate portions is also provided with the hot pressing longitudinally arranged and become.
Relevant content interpret in technique scheme is as follows:
1., in such scheme, folding is turned on described cover plate four limit downwards cover plate flange, and the vertical walls of this cover plate flange and case lid edge strip is stacked.
2., in such scheme, folding is upwards turned on described base plate four limit base plate flange, and the vertical walls of this base plate flange and case base bar is stacked.
The principle of design of the present invention and the effect brought are as follows:
The splicing structure being made up of sheet material, edge strip and cornerite it is designed at the bottom of the case lid of the present invention and case, under the nonstandard production of short run, cost is very low, and, at the bottom of its case and the intensity of case lid also guaranteed, phase specific tenacity at the bottom of the case lid shaping with prior art integrated die-casting and case does not decline, and ensure that the bearing of whole casing.
