Embodiment 1

[0039] refer to figure 1 As shown, a retractable packing box bottom structure, the bottom structure is a rectangular structure composed of pads 1 and connectors 2, the pads 1 are located at the four corners of the rectangular structure, there are four pads 1, each Each spacer 1 is L-shaped, and one end of the L-shaped spacer 1 is connected to a connecting piece 2, that is, a connecting piece 2 is arranged between two spacers 1 in the length direction of the rectangular structure. The spacer 1 mainly plays the role of buffering and supporting, and the connector 2 can be stretched according to the bottom size of the packaged product so as to change the size in the length direction.

[0040] Such as figure 1 , Figures 5-1 to 5-3 As shown, the connecting piece 2 includes a foam piece 21 and a diamond-shaped piece 22 on each side of the foam piece 21. The first slot 11 is provided at the end of the pad 1 connected to the connecting piece 2. The diamond-shaped piece 22 includes a...

Embodiment 2

[0047] refer to figure 2 The bottom structure of the telescopic packing box shown is different from Embodiment 1 in that connectors 2 are also arranged between the pads 1 in the width direction of the rectangular structure, and the structure of the connectors 2 is the same as in Embodiment 1. The pads The structure of 1 differs from that of embodiment 1 in that first slots 11 are provided at both ends to facilitate connection with the connector 2, so that the bottom structure can be stretched in both length and width directions. Others are the same as in Embodiment 1, and will not be repeated.

Embodiment 3

[0049] refer to image 3 The difference between the bottom structure of the telescopic packing box shown in Embodiment 1 is that the structural form of the connector 2 is different, and the connector 2 is two connecting units consisting of only two diamond-shaped parts 22 without foam parts 21 .

[0050] Such as Figure 7-1 , 7-2 As shown, when the connector 2 includes two connecting units, the connector 2 is made of two pieces of corrugated paper c, d, the middle of each piece of corrugated paper is provided with an insertion slot 224, and the two sides of the insertion slot 224 are respectively provided with front cutting lines e and the back knife line f, two pieces of corrugated paper c, d are folded along the knife line and then plugged together, and the two pieces of corrugated paper c, d are bonded and fixed at their two ends to form the first connecting part 222 to facilitate the connection with the spacer 1 The upper first slot 11 is plugged and fitted.

Abstract

The invention provides a stretchable packaging box bottom structure. The problems that in the prior art, the cost is high, and production is inconvenient are solved. According to the technical scheme, the stretchable packaging box bottom structure comprises a cushion block and a connecting piece. At least one end of the cushion block is connected with the connecting piece. The connecting piece is stretched and retracted according to the sizes of the bottoms of products to be packaged. The stretchable packaging box bottom structure is high in universality, the size of the stretchable packaging box bottom structure is correspondingly adjusted according to the different sizes of the products to be packaged, a plurality of pairs of dies do not need to be opened at the same time, the cost is greatly reduced, the structure is simple, manufacturing is convenient, and the bottom packaging structure of one model can be suitable for a series of products of the similar structures and different products changing in the length direction or width direction. The problem that household appliance packaging parts have wide varieties can be solved, and meanwhile EPS foamed plastic consumption can be reduced.

Description

[0001] technical field [0002] The invention belongs to the technical field of packaging boxes, and in particular relates to a scalable bottom structure of a packaging box. Background technique [0003] For the existing packing box bottom structure, for the same series of products with similar structure, the packaging foam is often not universal due to changes in product length or width, and multiple molds need to be opened; or mold parts are used on both sides, and cut foam parts are used in the middle (or other material) to connect. In order to meet different product sizes, the cut foam parts (or other materials) connected in the middle also have different sizes, which brings inconvenience to the production of the manufacturer and correspondingly increases the manufacturing cost. Contents of the invention [0004] The invention provides a retractable packing box bottom structure, which can solve the problems of high cost and inconvenient production in the prior art. ...
