the number of the locking pieces is 4 along the rectangular array of the box cover;

the locking part comprises a tensioning piece, one end of the tensioning piece extends to the bottom of the box body, the other end of the tensioning piece penetrates through the box cover and extends to the outside of the box cover, and a PVC baffle is arranged at the bottom of the tensioning piece;

the bottom of the box body is provided with a through hole for the PVC baffle to pass through.

The tightening piece extends to the upper part of the box cover and then penetrates through the rubber ring to be bound with the box cover.

The through holes are rectangular holes, the length of each rectangular hole is smaller than that of the PVC baffle, and the width of each rectangular hole is larger than that of the PVC baffle.

And an anti-slip layer is arranged on one surface of the PVC baffle close to the bottom of the box body.

Wherein, the tensioning piece is a nylon rope or a steel wire rope.

The box cover comprises a cover plate and a flange plate extending into the box body;

and a release paper layer is arranged on one surface of the flange plate, which is tightly attached to the inner wall of the box body.

The beneficial effects of the utility model are that, the utility model discloses a packing box locks case lid and bottom half through the retaining member together, when the case lid is carried to the staff, pulls up the bottom of box through the tensioning piece to make the whole hand of box in, solved traditional offering in the box upper end and carrying the hand, and the bottom does not bear the weight of the thing and leads to the bottom half to warp easily or damaged shortcoming, improves box transportation convenience.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1 and 4, the present embodiment provides a packing box, which includes a box body 1 and a box cover 2 movably connected to the box body 1, wherein the box cover 2 includes a cover plate 21 and a flange plate 22 extending into the box body 1; the one side that 1 inner wall of box was hugged closely to flange plate 22 is provided with from the type ply, pegs graft through the inner wall of flange plate 22 with box 1, forms and to dismantle the connection, and the article that conveniently seals in the box to tear from the type ply, can make flange plate 22 sticky with box 1's inner wall, strengthen the closeness of being connected of case lid 2 and box, simultaneously, because the adhesiveness on type ply is relatively poor, separate case lid 2 and box 1 easily, easy dismounting.

A locking piece 30 for integrally locking the box cover 2 and the box body 1 is also wrapped; the rectangular array of retaining member 30 has 4 along case lid 2, increases the hand inner point of box 1, improves the homogeneity of bottom atress when lifting box 1.

The locking member 30 comprises a tensioning member 31 with one end extending to the bottom of the box body 1 and the other end extending to the outside of the box cover 2 through the box cover 2, and a PVC baffle 32 is arranged at the bottom of the tensioning member 31; the bottom of box 1 is provided with the via hole 11 that is used for PVC baffle 32 to pass, before case lid 2 covers the box 1 closing cap, passes PVC board 32 via hole 11 to one side earlier, then lifts taut 31 for PVC board 32 joint is in the bottom outside of box 1, can carry out the pull-up to the bottom of box 1 simultaneously and ensure that the bottom half receives the pulling force, prevents the heavy object tenesmus, improves physique transportation security.

The locking member 30 further comprises a rubber ring 33, and the tensioning member 31 extends to the upper part of the box cover 2 and then penetrates through the rubber ring 30 to be bound with each other, so that the box cover is convenient to carry.

The via hole 11 is a rectangular hole, the length of the rectangular hole is smaller than that of the PVC baffle 32, the width of the rectangular hole is larger than that of the PVC baffle 32, and the PVC baffle 32 can obliquely penetrate through the via hole 11 and then is clamped at the bottom of the box body 1 to play a role in pulling up the box body bottom 1.

One side that PVC baffle 32 hugs closely the bottom half is provided with skid resistant course 321, and skid resistant course 321 chooses for use the rubber slab processing to form, makes its and 1 bottom of box closely laminate, and the stability of pulling up is improved to the not drunkenness.

The tensioning piece 31 is a nylon rope or a steel wire rope, and the tensioning force is reliable.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
