The coaming is the special plastic hollow plate, and the plate face loading capability and the periphery lateral loading capability (namely the cross section loading capability, the longitudinal section loading capability and even the inclined section loading capability) of the plastic hollow plate can reach to higher level in bearing so as to guarantee the strength of the whole coaming box.
Description
Technical field
The utility model relates to the Turnover Box field, is specifically related to a kind of folding hoarding box.
Background technology
Along with the quickening of china socialism's market economy system foundation, world economic integration process and the develop rapidly of science and technology, material flow industry conduct improves the important means of the market competitiveness and enterprise core competitiveness, but sees that at present the logistics of China also is not too modernization.As, the plastic box of indispensability in logistic industry, though through years development, the folded circulating box that various folded form occurred, but structural strength that must folding turnaround case still remains to be improved, particularly for folding turnover box made of hollowed board, it has advantages of lightweight, but generally acknowledges that also its intensity is relatively poor.Analysis is got up, the intensity of folding turnover box made of hollowed board depends primarily on the sheet material structure of the plastic hollow boards that adopts, existing common plastic hollow boards as shown in Figure 1, by two top layers 6 that are arranged in parallel, 7 and be connected to that muscle consists of between two top layers 6,7, be divided into vertical muscle 8 and oblique muscle 9 at the described muscle of cross-sectional plane, vertical muscle 8 and oblique muscle 9 one are arranged every one, and two top layers 6,7 spatial separation are become a plurality of subtriangular vertical passages 10 in cross section mutually arranged side by side.
When the hollow sheeting bearing was analyzed, three of definables were subjected to force direction: lateral cross section stressed (namely exerting pressure towards its lateral cross section), longitudinal cross-section stressed (namely exerting pressure towards its longitudinal cross-section) and plate face stressed (namely exerting pressure towards the sheet surface layer face).Above-mentioned existing plastic hollow boards light weight, but the bearing overbalance on its all directions, direction is arranged, except the bearing of lateral cross section when stressed strong, bearing when the stressed and plate face in its longitudinal cross-section is stressed is just very different, more yielding destruction when stressed and plate face is stressed in the longitudinal cross-section, namely existing plastic hollow boards comprehensive strength is relatively poor.
Summary of the invention
The utility model purpose provides a kind of heavier-duty hoarding box, improves intensity under the prerequisite that keeps light weight.
For achieving the above object, the technical solution adopted in the utility model is: a kind of heavier-duty hoarding box comprises at the bottom of case lid, coaming plate and the case;
Fixedly board and parallel two relative folding boards form described coaming plate by parallel relative two, fixedly establish the first folding line that hot pressing forms in the corner that joins of board and folding board at it on the described coaming plate, also be provided with the second folding line that the hot pressing of longitudinally arranging forms on the middle part of two folding boards;
And described coaming plate adopts plastic hollow boards, and the cross section of this plastic hollow boards comprises the interlayer between polymer top layer, lower polymer top layer and upper polymer top layer and the lower polymer top layer; Described interlayer is a polymer sheet material, is evenly equipped with projection and depression on the plate face of this polymer sheet material, this projection and be recessed in to look up towards the side of plate face and be circle; Described projection and be recessed in staggered layout on the plate face, make polymer sheet material at least one cross section be shaped as the concavo-convex shape that alternately rises and falls; The protruding end face of each of described interlayer is captiveed joint with upper polymer top layer, captives joint with lower polymer top layer in each bottom surface of caving in.
Related content in the technique scheme is explained as follows:
1, in the such scheme, and " described projection and be recessed in staggered layout on the plate face, make polymer sheet material at least one cross section be shaped as the concavo-convex shape that alternately rises and falls " comprise following concrete alternative arrangement scheme:
Projection on a, the described interlayer and depression matrix are arranged, and projection and be recessed on the row and column direction homogeneous every staggered, though each one week of projection upper adjacent all are depressions.If use this scheme, the cross section of the line direction of described polymer sheet material and the cross section of column direction all present the concavo-convex shape that alternately rises and falls.
Projection on b, the described interlayer and depression are the file arrangement, and same row are projection, and adjacent row are depression, and namely row projection one a row depression replaces.If use this scheme, the cross section of the line direction of described polymer sheet material presents the concavo-convex shape that alternately rises and falls.
Projection on c, the described interlayer and depression are projection for walking crosswise arrangement with delegation, and adjacent row is depression, and namely delegation's projection delegation depression replaces.If use this scheme, the cross section of the column direction of described polymer sheet material presents the concavo-convex shape that alternately rises and falls.
Projection and depression on d, the described interlayer can also be the multi-turn arranged in concentric circles, and a circle is raised or sunken entirely, i.e. the arrangement of a circle projection one circle depression; Can certainly enclose protrusions and depression one every one alternately occur at each.
2, in the such scheme, described interlayer is that the thickness of slab everywhere on the polymer sheet material equates.
3, in the such scheme, described projection and depression are truncated cone.In the reality, projection and depression can also be connected into by two sections even the multistage frustum of a cone, even projection and depression middle part have step.
4, in the such scheme, when the plastic hollow boards that adopts when coaming plate is thinner, described the first folding line and the second folding line are that the linear trace of wall scroll gets final product, but the plastic hollow boards that adopts when coaming plate is when thicker, and described the first folding line all can be comprised of two parallel linear traces with the second folding line.
Owing to having adopted above technical scheme, having the utlity model has following advantage:
Because coaming plate of the present utility model adopts plastic hollow boards, this plastic hollow boards cross section is connected and composed by three layers of upper epidermis, lower top layer and interlayers, and staggered circular protrusions and the depression of being evenly arranged on the interlayer, analyze theoretically, this structure can make interlayer support in the distribution of upper epidermis and following table interlayer uniformization to greatest extent, can be from a top layer Transmit evenly of power has been given full play to the efficient of interlayer to another top layer when making the plate face stressed, improves the bearing of plate face when stressed.And, because projection and depression are stressed also more even on its each side direction for circular, make that lateral force (is that lateral cross section is stressed, the longitudinal cross-section is stressed around the hollow sheeting, even oblique cross section is stressed) time bearing all reach higher level, use and can consider direction.In sum, the utility model compared with prior art comprehensive strength had significantly and to have improved.And coaming plate of the present utility model has the light weight advantage the same with prior art, and two surfaces of coaming plate can also keep higher planeness.
