As shown in fig. 1 to 3, the present invention provides a shockproof corrugated carton, which at least comprises: the assembled internal carton 10 and the assembled external carton 20 are disassembled, wherein the external side surface of the internal carton 10 and the internal side surface of the external carton 20 are provided with matched clamping components, the internal bottom surface of the external carton 20 is provided with a shockproof buffer pad 50 and a corner protection pad 40, and the corner protection pad 40 is arranged at four corners of the internal bottom surface of the external carton 20.

Specifically, the internal carton 10 is provided with an internal accommodating chamber with a single side opening, and the external carton 20 is provided with an external accommodating chamber with a single side opening, wherein the shape and size of the external accommodating chamber are matched with those of the internal carton 10. In an embodiment of this scheme, built-in carton 10 is cuboid box structure, and corresponding, external accommodation chamber is the cuboid cavity.

The outer side of the built-in carton 10 is provided with clamping ribs 31 protruding outwards at intervals, and the inner side of the external carton 20 is provided with corresponding clamping grooves 32 recessed inwards. In the embodiment of the present disclosure, the clamping ridge 31 and the clamping groove 32 are vertically disposed, and the clamping groove 32 is spaced from the bottom surface of the external accommodating chamber of the external carton 10 by a certain distance, so that when the internal carton 10 is placed in the external carton 20, the internal carton 10 can be relatively positioned and fixed, and meanwhile, the bottom surface of the internal carton 10 does not directly contact the external carton 20.

In the embodiment of the present embodiment, the card slot 31 and the card slot 32 have a rectangular bar structure. The clamping ribs 31 are respectively arranged on four sides of the internal carton 10, and correspondingly, the clamping grooves 32 are respectively arranged on four sides of the external carton 20.

The corner protection pads 40 are disposed at four corners of the external accommodating chamber of the external carton 20, wherein the corner protection pads 40 are three-sided structures with three sides intersecting each other two by two, and the corner protection pads 40 abut against three sides of the external accommodating chamber. In the embodiment of the present disclosure, the corner protection pad 40 is made of rubber.

When the internal carton 10 is clamped in the external carton 20, four corners of the internal carton 10 are protected by the corner protection pads. And the height of the corner protection pad 40 is changed, so that the same external carton 20 can be matched with the internal cartons 10 with different heights.

The shock-proof cushions 50 are spaced apart from each other at the bottom of the external receiving chamber, and when the internal carton 10 is placed in the external carton 20, the shock-proof cushions 50 are placed at the bottom of the internal carton 10 and contact the internal carton 10.

As shown in fig. 2, the crash pad 50 includes a pad plate 51 and an arc-shaped elastic sleeve 52 disposed on the pad plate 51, wherein a shock-absorbing spring 53 is connected between the arc-shaped elastic sleeve 52 and the pad plate 51. In some embodiments, the crash pad 50 includes a plurality of arc-shaped elastic sleeves 52, and a shock-absorbing spring 53 is connected between each of the arc-shaped elastic sleeves 52 and the pad 51.

The curved surface of the curved elastomeric sleeve 52 contacts the interior carton 10.

In addition, the built-in carton 10 of the present disclosure is made of a special shockproof corrugated cardboard, wherein the shockproof corrugated cardboard has a structure shown in fig. 3, and the shockproof corrugated cardboard includes a first corrugated cardboard 11, a reinforced straight corrugated cylinder 14, and a second corrugated cardboard 12 connected in sequence from top to bottom, wherein the first corrugated cardboard 11 and the second corrugated cardboard 12 are arranged in parallel at intervals, and at least two reinforced straight corrugated cylinders 14 are adhered between the first corrugated cardboard 11 and the second corrugated cardboard 12 at intervals.

The cross section of the reinforcing corrugated straight cylinder 14 is circular, which can well disperse the acting force acting on the first corrugated board 11 or the second corrugated board 12, thereby increasing the shock absorption and shock resistance of the built-in carton 10.

In some embodiments, in order to optimize the seismic performance of the reinforced corrugated straight cylinder 14, the inside of the reinforced corrugated straight cylinder 14 is filled with the seismic filler 15.

In some embodiments, the rubber sheet 13 is sleeved at the middle end position of the outer wall of the plurality of reinforced straight corrugated tubes 14, the upper end surface and the lower end surface of the rubber sheet 13 do not adhere to the first corrugated cardboard 11 or the second corrugated cardboard 12, and the plurality of reinforced straight corrugated tubes 14 can be connected through the rubber sheet 13 to better disperse the external force acting on the first corrugated cardboard 11. It is particularly worth mentioning that the rubber sheet is a sulfur-containing hard rubber sheet.

In the embodiment of the present disclosure, the outer carton 20 may be made of a common corrugated cardboard, and the inner carton 10 is made of a special shockproof corrugated cardboard, which also reduces the manufacturing cost of the shockproof corrugated carton.

In summary, when the shockproof corrugated carton is used for packaging and transporting a certain product, the product can be placed in the internal carton 10 made of shockproof corrugated paper, and then the internal carton 10 is placed in the external carton 20 by using the matching positioning card of the clamping ribs 31 and the clamping grooves 32 (of course, the internal carton 10 can be placed in the external carton 20 first), at this time, the bottom of the internal carton 10 contacts the shockproof cushion 50, and four corners of the bottom of the internal carton 10 are surrounded by the corner protection pads 40. If the shockproof corrugated case shakes during transportation, external impact force firstly reaches the external corrugated case 20 and is partially offset, then is transmitted to the corner protecting pad 40 and the shockproof buffer pad 50 to be absorbed, and finally is absorbed by the shockproof corrugated paper. Moreover, the transportation personnel only need to transfer the built-in carton 10 when transferring the product, and do not need to transfer the whole shockproof corrugated carton.

The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by the teaching of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention.
