Description

One-piece 3X3 knife card cutting piece

Technical Field

The utility model belongs to carton packing field specifically is a piece formula 3X3 sword card cut-parts.

Background

The knife clip, also called as a partition or a grid, is generally used in the packing box to separate a plurality of independent spaces, and each packed article independently occupies one independent space without interference, thereby facilitating the space utilization of the packing box. The traditional knife clip is formed by inserting a plurality of longitudinally-arranged separating sheets and a plurality of transversely-arranged separating sheets in a staggered manner in a # -shape manner, so that the folding forming efficiency of the knife clip is low, the knife clip is inconvenient to use, and the knife clip is easy to damage in the forming and using processes, so that the recycling is difficult. Chinese patent document CN202244454U discloses "disjunctor well word sword card" in 2012 5 months 30 days, insert to close the structure that forms the bottom and form the stationary plane by two disjunctor sword cards, wherein, form the socket in the middle of a slice sword card, another piece sword card limit forms the slot along cooperation department, and two sword cards correspond the slot after buckling and insert the location with the socket position, the utility model discloses two liang of continuous non-deformable of disjunctor well word sword card, especially the packing edge is difficult to warp when heavier material, protects the product, and the transport condition is abominable then selects disjunctor sword card protection better. This prior art, though compress traditional many vertical septa and many horizontal septa respectively to on one cut-out, still remain two cut-outs, fail further adoption single cut-out preparation sword card, consequently still have further optimized space.

SUMMERY OF THE UTILITY MODEL

The number of combined cut pieces of the existing knife card cannot be less than two. Based on the problem, the utility model provides a one-piece formula 3X3 sword card cut-parts to the sword card of 3X3 specification is made in the folding of single cut-parts has the advantage that the folding shaping is convenient, the use is convenient, retrieve easily.

In order to realize the purpose of the invention, the utility model adopts the following technical scheme: a one-piece type 3X3 knife card cutting piece comprises a left longitudinal piece, a right longitudinal piece, an upper transverse piece and a lower transverse piece, wherein two longitudinal piece slots with openings towards the outside are respectively arranged on the outer side edges of the left longitudinal piece and the right longitudinal piece, two transverse piece slots with openings towards the outside are respectively arranged on the outer side edges of the upper transverse piece and the lower transverse piece, the longitudinal piece slots and the transverse piece slots are matched and oppositely inserted, and the one-piece type 3X3 knife card cutting piece also comprises a central piece with a rectangular shape; the upper side edge of the central piece is connected with the lower side edge of the upper transverse piece through an upper connecting piece, and the lower side edge of the central piece is connected with the upper side edge of the lower transverse piece through a lower connecting piece; the two transverse piece slots on the upper transverse piece and the lower transverse piece are uniformly distributed on the extension lines of the left longitudinal edge and the right longitudinal edge of the central piece; the left side and the right side of the central piece are respectively connected with the inner sides of the left longitudinal piece and the right longitudinal piece, and two longitudinal piece slots on the left longitudinal piece and the right longitudinal piece are equally distributed on extension lines of the upper transverse edge and the lower transverse edge of the central piece.

Folding to vertical to the inboard through indulging piece and the right side of indulging piece in with a left side, inwards folding to vertical with last connection piece and lower connection piece, will go up horizontal piece and the horizontal piece is outwards folded to vertical again to it is fixed to carry out the antithetical couplet with horizontal piece slot and vertical piece slot, can obtain a 3X 3's sword card structure, wherein the space placed in the middle uses the center piece as the end, and 8 spaces on every side all are bottomless. In this structure, it is generally required that the left longitudinal piece, the right longitudinal piece, the upper transverse piece and the lower transverse piece are rectangular, and the transverse and vertical directions are consistent with the central piece. In special cases, the above structure can be adapted, for example, if the central piece is a parallelogram, the left longitudinal piece, the right longitudinal piece, the upper transverse piece and the lower transverse piece will be changed into the corresponding parallelogram according to the shape of the central piece, and the folded knife card is cross-shaped. The central piece is a quadrangle with an irregular shape, and the two longitudinal pieces and the two transverse pieces are not parallel to each other and are not parallel to each other when the knife clip is formed by folding. The shape of the central piece can be selected by those skilled in the art according to the actual design requirements, and the final folding effect of the knife card can be further determined.

Preferably, the upper connecting piece and the lower connecting piece have a longitudinal length equal to that of the upper cross piece and the lower cross piece. When the upper transverse sheet and the upper connecting sheet are in a state of being attached to the back surface after being folded, the upper transverse sheet has full height, and a gap cannot be formed below the upper transverse sheet to influence the partition effect. The lower connecting sheet is processed in the same way.

Preferably, the longitudinal lengths of the upper horizontal piece and the lower horizontal piece are equal to the transverse lengths of the left vertical piece and the right vertical piece. This design provides a fold-formed knife card with a substantially uniform upper surface for subsequent stacking, box sealing, etc.

Preferably, the outer side end of the longitudinal piece slot is provided with a guide structure. The guide structure is used, so that the mutual insertion operation of the transverse piece slot and the longitudinal piece slot can be facilitated.

Preferably, the guide structure is a fan-shaped notch; one side edge of the fan-shaped notch is the inner side edge of the longitudinal piece slot, and the other side edge is the outer side edge of the left longitudinal piece or the right longitudinal piece. By using the wire structure in the shape of the fan-shaped notch, the transverse sheet slot can slide along the fan-shaped arc edge during the insertion until the positioning insertion with the longitudinal sheet slot is finished at last. According to the scheme, the upper transverse sheet and the lower transverse sheet do not need to be bent, and the splicing is realized by means of the elastic deformation of the upper transverse sheet and the lower transverse sheet, so that the operation is simpler and faster, and the upper transverse sheet and the lower transverse sheet cannot yield under the action of stress and further the strength is influenced due to the bending action during the operation.

Preferably, the upper transverse sheet and the lower transverse sheet are divided into three equal parts by the two transverse sheet slots; the left longitudinal piece and the right longitudinal piece are longitudinally divided into three equal parts by two longitudinal piece slots. According to the design scheme, each space formed by the knife clip is provided with the transverse edge and the longitudinal edge which are as long as the central sheet, so that the cross section of each space is completely equal to that of the space where the central sheet is located.

To sum up, the beneficial effects of the utility model are that: the knife clip with the specification of 3X3 is made by folding a single cutting piece, and has the advantages of convenient folding and forming, convenient use and easy recovery.
