Also be provided with the identical bookbinding screw of bookbinding hole number with said interior page or leaf bag; Said bookbinding screw penetrates the bookbinding hole of the complete matching of the lower installation board that page or leaf bag, said lower hem film and said back cover outside plates are provided with in all of the upper mounting plate that said front cover outside plate is provided with, said upper hem film, said volume core successively, and the lower installation board that page or leaf bag, said lower hem film and said back cover outside plates are provided with in all of the upper mounting plate that said front cover outside plate is provided with, said upper hem film, said volume core is made up of said bookbinding screw and is removably connected.
The technical problem of the utility model solves through following further technical scheme.
Said front cover outside plate, back cover outside plate are to be fit to a kind of in colored printing or gold stamping paper, the plastic film.
Said back of the body bar film is to be fit to a kind of in colored printing or the gold stamping plastic film.
Said suitable colored printing or gold stamping paper are a kind of in art paper, art post paperboard, coated duplex board with grey back, gold and silver paperboard and the laser film paperboard.
The plastic film of said suitable colored printing is a kind of in polyethylene film, polypropylene film, stretched polypropene film and the polyester film.
Said suitable gold stamping plastic film is a polyvinyl chloride film.
The beneficial effect of the utility model and prior art contrast is:
The utility model is simple in structure, and moulding is attractive in appearance, and crushing resistance is strong, not cracky.Spread when arrangement out, it is flat to lie fully, is easy to open search and array data, and spreads arrangement out and also have the block phenomenon when preserving with standing.Especially capacity is big, and interior page or leaf pocket facing closes closely, saves space, capacity storage data greatly.The data volume that the utility model can be widely used as the file management folder and comprise name card pad and photograph album.
The specific embodiment
Below in conjunction with the specific embodiment and contrast accompanying drawing the utility model is described.
A kind of like breakover formula data volume shown in the drawings, comprise a core, envelope ridge, front cover outside plate 1 and back cover outside plate 2.
The volume core comprises page or leaf bag 3 at least one, in each binding side of page or leaf bag 3 be provided with two with other in the bookbinding hole 4 of page or leaf bag complete matching.
The envelope ridge is the breakover film; Cross section by the centre is the back of the body bar film 5 of circular arc and extends the upper hem film, the lower hem film that are connected with back of the body bar film 5 both ends of the surface respectively and form; Back of the body bar film 5 is to be fit to the colored printing polyethylene film; Its width equates that with all interior page or leaf bag thickness of volume core the binding side of interior page or leaf bag 3 places between upper hem film, the lower hem film, and upper hem film, lower hem film are respectively equipped with two bookbinding holes of binding hole 4 complete matchings with interior page of bag 3.
Front cover outside plate 1, back cover outside plate 2 are independently to be fit to colored printing or gold stamping art paper flat board mutually; Front cover outside plate 1 mutually internally the binding side of page or leaf bag 3 be provided with the upper mounting plate of 180 ° of downward turnovers; Upper mounting plate is provided with two bookbinding holes of binding hole 4 complete matchings with interior page or leaf bag 3; Back cover outside plate 2 mutually internally the binding side of page or leaf bag 3 be provided with the lower installation board that upwards turns down 180 °, lower installation board is provided with the bookbinding holes 6 with two bookbinding hole 4 complete matchings of interior page or leaf bag 3.
Also be provided with the two secondary bookbinding screws 7 identical with bookbinding hole 4 quantity of interior page or leaf bag 3; Be commonly called as master and slave dowel or account book screw, photograph album screw; Two secondary bookbinding screws 7 penetrate two bookbinding holes of the complete matching of the lower installation board that page or leaf bag, lower hem film and back cover outside plates 2 are provided with in all of upper mounting plate that front cover outside plate 1 is provided with, upper hem film, volume core respectively successively and bind the one that becomes to removably connect, and are these goods.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.Those of ordinary skill for technical field under the utility model; Under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; And performance or purposes are identical, all should be regarded as belonging to the scope of patent protection that the utility model is confirmed by claims of being submitted to.
