In the folding plastic turnover box, a box body is formed by the way that five single chips are connected by a metal locking shaft through a hinge connected structure; a box body frame which can be one-way folded is formed by the way that two long edge frame pieces and two short edge frame pieces are connected by a locking shaft; one side of a bottom piece and the long edge frame pieces are connected by a circular arc-shaped female-male tenon hinge connected structure; e the other side is not connected, and can upward be turned and folded 90 DEG. At the time of bearing weight, the bottom piece is used for supporting the four edge frame pieces to fix the box body, and the ditch-shaped fixed groove of the short edge frame piece, the concave groove of the bottom piece, and the female-male tenon hinge connected structure and the pressure bearing support edge of the long edge frame piece are used for bearing the weight. At the time of being folded, the bottom piece is pushed up to combined with the long edge frame piece, and four frames are rejoined. The folding plastic turnover box can be the conveniently used and folded.

Description

Folding plastic turnover box

The utility model belongs to the plastics industry goods.

In commodity circulation, plastic box is being born very important role, the turnover of many industry goods and transportation are all being used plastic box, freezer is stored the turnover of goods, diet vegetables industry, beverage, food, transmission of vegetables and various Toy Factory, Cosmetics Plant, industrial and mining enterprises produce the workshop of parts, Glassware Factory etc., all have enough to meet the need in the transportation and all use various plastic boxes, plastic box is the most basic packing in the existing transportation, the case of migrating in week, though existing Turnover Box purposes is very extensive, but all have a common fault: the empty van floor area is the same with at full load, make that the carrying of turnover space-time is defeated, cause manpower, the significant wastage of financial resources, and having caused the storehouse anxiety, incompatibility manufacturer storehouse is stored and is called.

The utility model is at above-mentioned reality, design has proposed a kind of plastic box that can fold, simple in structure, use very convenient, it will make the unloaded floor area of Turnover Box dwindle greatly, save unloaded spending, improve the storehouse service efficiency simultaneously, tank farm stock can increase considerably, and can reach 3-4 times of former tank farm stock.The folding plastic Turnover Box has solved the common fault of existing Turnover Box, has incomparable advantage.

The folding plastic Turnover Box is shaped as oblong, is similar to the beer case that uses on the market.Folding turnaround case links structure by five by strand and is formed with the monolithic that the metal bearing pin is connected, the metal bearing pin is an end band cap, and the other end is equipped with the thin bar of pin hole, and five monolithics are divided into three kinds: the egative film that can dig folding, two long margin frame sheets, two minor face frame sheets.All be processed with many reinforced ribs and lightening hole on each monolithic, the long margin frame sheet links structure with minor face frame sheet by the strand that is similar to hinge and links to each other.Minor face frame sheet is that two ends, left and right sides end face is provided with the sheet that strand links structure, and be manufactured with ditch shape hold down groove in the inboard, base, the long margin frame sheet be on one side invagination the sheet of 90 ° of little bent faces, the invagination size is consistent with the thickness of egative film, the strand that does not all have to be connected with minor face frame sheet at the end face of interior folding surface and long margin frame sheet another side end face links structure, linking structure with the metal bearing pin by strand can be connected two long margin frame sheets with two minor face frame sheets, can only be and form along the folding rectangular box frame of a direction, be manufactured with special strand in long margin frame length of a film limit lower inside and link structure and pressure-bearing holder limit, the strand company headquarters that this strand links structure is divided into circular arc mortise and tenon structure, be used for linking to each other with egative film, egative film is the oblong sheet, and two long limits of egative film all are manufactured with the circular arc mortise and tenon strand that matches with long margin frame sheet bottom and link structure.During assembling, egative film only links structure with the mortise and tenon strand of one side long margin frame sheet and is connected by bearing pin, another side does not connect, egative film can upwards be dug, give over to the usefulness of exchange when damaging simultaneously, two minor face limit portions in the egative film bottom surface are manufactured with the Baltimore groove that the ditch shape hold down groove with minor face frame sheet matches, the inside dimension of the rectangular box that forms is consistent with the outside dimension of egative film because the long margin frame sheet links to each other with minor face frame sheet, so fixed the stable of box shape by egative film, when Sheng is heavy, egative film is respectively by the ditch shape hold down groove of minor face frame sheet, the bearing pin mortise and tenon of long margin frame sheet strand links structure on one side, the mortise and tenon strand binding structure and the pressure-bearing holder limit of another long margin frame sheet are stressed, thereby form a firm integral body, when folding, boost egative film from the bottom, egative film links 90 ° of structure upsets along bearing pin mortise and tenon strand, with one side long margin frame sheet mutually and close, close up four frame sheets again, promptly become a long flat sheet, its thickness is that three egative films are thick.

Below in conjunction with Figure of description and embodiment the utility model is further described.

This folding plastic Turnover Box material adopts polypropylene, ABS engineering plastics, most preferred embodiment folding plastic Turnover Box removes metal bearing pin external-talent and expects all to adopt polypropylene, and rectangular box is by two the long margin frame sheets (1) that all are manufactured with many reinforced ribs (10) and lightening hole (11), two minor face frame sheets (2) and can dig the egative film (3) of rolling over 90 ° and be formed.Link structure with bearing pin (4) by strand binding structure (5) that is located at interior folding surface end face in long margin frame sheet one side and long margin frame sheet another side end face and the strand that minor face frame sheet the right and left end face is manufactured with, two long margin frame sheets can be connected in two minor face frame sheets, egative film links structure (6) by special circular arc mortise and tenon strand and links to each other with bearing pin with the long margin frame sheet of a side, opposite side do not connect and make egative film can go up the folding dig, when using this folding carton, prop up four frame sheets by egative film, again by minor face frame sheet ditch shape hold down groove (7), egative film Baltimore groove (8), long margin frame sheet bearing pin mortise and tenon strand link structure and pressure-bearing holder limit (9) and bear weight pressure and form the firm loaded van body that is subjected to; When folding, only need boost egative film from the bottom, make it with a side long margin frame sheet and close, close up four frame sheets again and get final product.

This novel folding plastic box technology is simple, and use, folding all very convenient has the incomparable advantage of existing Turnover Box. Annotate: Figure of description (1) is positive isometric view cutaway view, and figure (2) is folding schematic diagram.

Claims (1)

1, the folding plastic Turnover Box is made up of two long margin frame sheets, two minor face frame sheets, egative film, metal bearing pins, feature of the present utility model is: two long margin frame sheets and two minor face frame sheets link by strand that structure is connected to become with the metal bearing pin can only be along folk prescription to the box frame that folds, egative film one side links structure with the long margin frame sheet with special circular arc mortise and tenon strand and links to each other, opposite side does not connect, and makes egative film can dig 90 ° of foldings; Its material selection polypropylene, the ABS engineering plastics.
