Description

Technical Field

[0001] The utility model relates to the field of packaging materials, in particular to a PDQ with corner post reinforcement. Background Art

[0002] The basket-type PDQ is a commonly used PDQ at present. The structure of this PDQ is shown in the patent publication document CN307969365S. Four sheet plates are arranged at the uppermost part of the four folding corners of the PDQ shown in this structure. The function of these four sheet plates is to support the upper PDQ when the PDQ is stacked. However, for the PDQ with this structure, since only the sheet plates are relied on to support the upper PDQ, and the sheet plates are only fixed to the side walls of the PDQ at both ends, the sheet plates are extremely prone to tilt and collapse towards the bottom of the PDQ when bearing pressure. Once the sheet plates tilt and collapse towards the bottom of the PDQ, the support strength of the sheet plates for the upper PDQ is greatly reduced, resulting in the collapse of the stacked PDQ. Summary of the Utility Model

[0003] Aiming at the above problems, the utility model provides a PDQ with corner post reinforcement. By arranging support pipes inside the sides and using the support pipes for support during stacking, the whole PDQ has good support stability, and the whole PDQ is not prone to being crushed during stacking.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A PDQ with corner post reinforcement includes a bottom sheet, a first end sheet, a second end sheet and side sheets. The first end sheet, the second end sheet and the side sheets are all arranged on the bottom sheet. The first end sheet and the second end sheet are in a parallel state. There are two side sheets, and the two side sheets are respectively located between the first end sheet and the second end sheet. It further includes support pipes and cover sheets. The support pipes are arranged at both ends of the first end sheet and the second end sheet. The cover sheets are arranged on the side sheets, and the cover sheets are matched with one end of the support pipes. The support pipes are perpendicular to the bottom sheet.

[0006] Specifically, in this PDQ with corner post reinforcement, the support pipes and the cover sheets are combined to form a corner post. One end of the corner post is the bottom sheet, and the other end of the corner post is the cover sheet. Therefore, the corner post itself has good stability.

[0007] In this type of reinforced PDQ, the first end piece, the second end piece, and the two side pieces enclose a rectangular side part on the bottom piece. The two side pieces of this side part are parallel and non - contacting, the first end piece and the second end piece are parallel and non - contacting, and the two are perpendicular to the first end piece and the second end piece. This side part is perpendicular to the bottom piece. There are a total of four support tubes, and the four support tubes are respectively located at the four corners of the side part and are inside the side part. When stacking PDQs, the support tubes on the PDQ below can be used to support the bottom piece of the PDQ above. Since one end of the support tube abuts against the bottom piece and the other end of the support tube is a cover piece, the support tube can stably support the PDQ above.

[0008] In summary, in this type of corner - column - reinforced PDQ, by arranging support tubes inside the side part and using the support tubes for support during stacking, it ensures that the entire PDQ has good support stability, and the entire PDQ is not easily crushed during stacking.

[0009] Optionally, it further includes a first clamping piece and a second clamping piece. The side piece is provided with the first clamping piece, the second clamping piece is arranged on the cover piece, and the first clamping piece and the second clamping piece cooperate with the support tube.

[0010] Specifically, the functions of the first clamping piece and the second clamping piece are to closely adhere to and clamp the support tube to ensure that the support tube has good stability inside the side part. Specifically, when the first clamping piece and the second clamping piece closely adhere to and clamp the support tube, the first clamping piece and the second clamping piece are in the same plane.

The structure of the insertion and the slot engagement can not only ensure that the entire triangular - prism - shaped support tube has good stability, but also ensure that it can be quickly disassembled as needed during disassembly.

[0012] In this type of PDQ, through the functions of the cover piece, the first clamping piece, and the second clamping piece, it is equivalent to blocking the pipe orifice of the support tube, avoiding the exposure of the pipe orifice of the support tube and scratching the user.

[0013] Optionally, the support tube includes a first support piece, a second support piece, and a third support piece, and the first support piece, the second support piece, and the third support piece enclose a hollow triangular - prism - shaped support tube.

[0014] The support tube of this species is a right-angled triangular prism-shaped support tube. The right-angled vertex of the support tube is closely attached to the inner right angle of the side part, which can improve the anti-twisting ability of the entire side part, making the whole PDQ less likely to be squeezed and deformed. At the same time, since the right-angled vertex is closely attached to the side part, it is equivalent that each wall surface of the support tube is composed of two layers, which can ensure that the whole support tube can have good support strength.

[0015] The two ends of the specific support piece are respectively the first support piece and the third support piece. The first clip and the second clip are both closely attached to the first support piece. The slot is opened on the first support piece, and the cover piece is stuck at one end of the hollow triangular prism-shaped support tube.

[0016] Optionally, it further includes a first reinforcing piece. One end of the first reinforcing piece is connected to the first end piece, and the other end of the first reinforcing piece is inserted and matched with the bottom piece. The support tube is arranged at both ends of the first reinforcing piece.

[0017] The specific function of the first reinforcing piece is to strengthen the support and compressive strength of the first end piece. The first reinforcing piece and the first end piece are in a closely attached and flush state.

[0018] Optionally, it further includes a second reinforcing piece. One end of the second reinforcing piece is connected to the second end piece, and the other end of the second reinforcing piece is inserted and matched with the bottom piece. The support tube is arranged at both ends of the second reinforcing piece.

[0019] The specific function of the second reinforcing piece is to strengthen the support and compressive strength of the second end piece. The second reinforcing piece and the second end piece are in a closely attached and flush state.

[0020] Optionally, both the first end piece and the second end piece are provided with fitting pieces, and the fitting pieces are used for closely fitting with the side piece.

[0021] The fitting pieces on the first end piece and the second end piece are closely fitted with the side piece, which is to ensure that the entire side part has high stability.

[0022] Specifically, both ends of the first end piece and the second end piece are provided with fitting pieces. The fitting pieces at both ends of the first end piece are respectively fitted with two side pieces, and the fitting pieces at both ends of the second end piece are respectively fitted with two side pieces. The two fitting pieces on the first end piece are in a parallel and non-contact state, and the two fitting pieces on the second end piece are in a parallel and non-contact state.

[0023] Optionally, both the first end piece and the second end piece are provided with locking holes, and the side piece is provided with locking pieces, and the locking pieces are matched with the locking holes.

[0024] Locking holes are formed in the first end piece and the second end piece, and locking pieces are arranged on the side piece. By using the locking cooperation between the locking pieces and the locking holes, the stability of the fitting piece and the side piece during fitting can be improved.

[0025] Optionally, the bottom piece is a rectangular bottom piece.

[0026] The beneficial effects of the present utility model are as follows: By arranging a triangular prism support tube inside the side part, the support performance in the vertical direction and the anti-twisting performance in the horizontal direction are improved by using the support tube during transportation and stacking, ensuring that the entire PDQ has good structural stability, and it is not easy to collapse during transportation and stacking.

[0036] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art may make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0037] As shown in the attached Figure 1 , attached Figure 2 , attached Figure 3 , attached Figure 4 , attached Figure 5 and attached Figure 6 shown, a corner post reinforced PDQ includes a bottom sheet 1, a first end sheet 21, a second end sheet 22, and side sheets 4.

[0038] Referring to the attached Figure 6 shown, after folding and forming, the heights of the side sheets, the first end sheet, the second end sheet, the first reinforcing sheet, and the second reinforcing sheet are flush.

[0039] Specifically, in this type of corner post reinforced PDQ, the support tube and the cover sheet 5 are combined to form a corner post. One end of the corner post is the bottom sheet 1, and the other end of the corner post is the cover sheet 5. Therefore, the corner post itself has good stability.

[0040] In this type of reinforced PDQ, the first end sheet 21, the second end sheet 22, and the two side sheets 4 enclose a rectangular side portion on the bottom sheet 1. The two side sheets 4 of the side portion are in a parallel and non-contact state. The first end sheet 21 and the second end sheet 22 are in a parallel and non-contact state. The two are perpendicular to the first end sheet 21 and the second end sheet. The side portion is perpendicular to the bottom sheet 1. There are a total of four support tubes, and the four support tubes are respectively located at the four corners of the side portion, and the support tubes are located inside the side portion. When the PDQ is being stacked, the support tubes on the PDQ below can be used to support the bottom sheet 1 of the PDQ above. Since one end of the support tube abuts against the bottom sheet 1 and the other end of the support tube is the cover sheet 5, the support tube can stably support the PDQ above.

[0041] In summary, in this type of corner post reinforced PDQ, by providing support tubes inside the side portion and using the support tubes for support during stacking, it ensures that the entire PDQ has good support stability. The entire PDQ during stacking (the state during stacking can be referred to in the attached Figure 7As shown in [reference], it is not prone to the phenomenon of being crushed.
