Description

Technical Field

[0001] This application relates to the technical field of paper pallets, and more particularly to a paper pallet that is resistant to compression deformation. Background Technology

[0002] Paper pallets are a type of packaging container made of paper as the core raw material, which is formed by cutting, folding, splicing or molding. They are mainly used for carrying, stacking and transporting goods.

[0003] A search revealed Chinese Patent Publication No. CN223200543U, which discloses a paper pallet comprising a cardboard base, multiple side panels (first and second), and side panels (second). Side panels (first and second) are disposed along the edge of the base, and are integrally formed. The base has multiple slots arranged in pairs, extending to the side panels. A protrusion (first) is formed in the base area between two paired slots, and a protrusion (second) is formed in the side panel area between two paired slots. When the side panels are perpendicular to the base, protrusion (first) is perpendicular to the base, and protrusion (second) is perpendicular to the side panels. This application improves the structural strength of paper pallets.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following defects: In the prior art, by setting an abutment at the connection between protrusion one and protrusion two, when the user assembles the cardboard into a box, the abutment can be inserted into the protrusion. At this time, the locking rod is locked on the inner wall of the box, and the locking plate is tilted and abuts against the connection between protrusion one and protrusion two, thereby keeping protrusion one perpendicular to the bottom plate and protrusion two perpendicular to the side plate, thus improving the structural strength of the protrusion. However, when side plate one and side plate two are squeezed, the abutment and the protrusion cannot effectively support side plate one and side plate two, thereby causing the pallet to deform. To address the problem in existing technologies where the mating parts and protrusions cannot effectively support side panels one and two, this application incorporates a third retaining plate and a seventh folding area. The outer wall is formed by vertically folding the first, second, fourth, and sixth folding areas around the cardboard fold lines, followed by folding the fifth and seventh folding areas to form the inner wall. After folding, the third retaining plate is inserted into the third positioning hole in the seventh folding area, providing effective vertical support to the seventh and fifth folding areas of the inner wall, thus enhancing the strength of the paper pallet's sides. Utility Model Content

[0005] In order to solve the problem that the mating parts and protrusions in the prior art cannot effectively support the first and second side plates, this application provides a paper pallet that prevents deformation due to compression.

[0006] This application provides a paper tray to prevent deformation by squeezing, which adopts the following technical solution: it includes a cardboard, on which a first folding area, a second folding area, a fourth folding area, and a fifth folding area are provided. The first folding area is provided with a sixth folding area, a seventh folding area, and a third folding area. The sixth folding area is provided with a first cardboard plate on both sides. The fifth folding area is provided with a second cardboard plate. The cardboard is provided with a third cardboard plate on top.

[0007] Optionally, there are two symmetrically arranged first folding areas and two fixedly connected to the cardboard, with fold lines at the connection points.

[0008] Optionally, a sliding hole is provided on the second folding area, and a handle is provided on the sliding hole, the handle being slidably connected to the second folding area.

[0009] Optionally, the fourth folding area is fixedly connected to the second folding area, and a fold line is provided at the connection point. The fourth folding area is also provided with a first positioning hole for the first card plate to be inserted.

[0010] Optionally, the second card plate is fixedly connected to the fifth folding area, and the fifth folding area is fixedly connected to the fourth folding area, with fold lines provided at the connection points.

[0011] Optionally, the cardboard is provided with a second positioning hole, and the second card can be inserted into the second positioning hole after being folded.

[0012] Optionally, the sixth folding area and the first card plate are both fixedly connected to the first folding area, and a fold line is provided at the connection point; the seventh folding area is fixedly connected to the sixth folding area.

[0013] Optionally, a third positioning hole is provided on the seventh folding area, and a fold line is provided on the third card plate. After folding, it can be inserted into the third positioning hole, and the third folding area is fixedly connected to the seventh folding area.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. This utility model forms an outer wall by vertically folding the first, second, fourth, and sixth folding areas around the fold line, and forming an inner wall by folding the fifth and seventh folding areas. Then, a third card plate is inserted into the third positioning hole of the seventh folding area to provide vertical and stable support for the seventh and fifth folding areas of the inner wall, which greatly reduces the risk of deformation of the pallet due to lateral force and significantly improves the paper pallet's resistance to compression.

[0016] 2. This utility model, by providing a first positioning hole and a second positioning hole, and the fixed connection between the first folding area and the sixth, seventh, and third folding areas, along with the insertion of the first positioning hole of the fourth folding area into the first cardboard and the insertion of the second cardboard into the second positioning hole of the cardboard in the fifth folding area, forms a multi-dimensional locking structure, which improves the stability of the pallet; the handle slidably connected on the second folding area provides a convenient force application point for pallet handling, improving handling efficiency.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figures 1-5 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] This application discloses a paper tray that prevents deformation due to compression. For example... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, it includes cardboard 1, on which a first folding area 2, a second folding area 3, a fourth folding area 4, and a fifth folding area 5 are provided. On the first folding area 2, a sixth folding area 7, a seventh folding area 8, and a third folding area 9 are provided. On both sides of the sixth folding area 7, a first card plate 10 is provided. On the fifth folding area 5, a second card plate 6 is provided. On the top of the cardboard 1, a third card plate 15 is provided.

[0025] Please see Figure 1 , Figure 2 There are two symmetrical folding areas 2 and 3, located on opposite sides of the cardboard 1 and fixedly connected to the cardboard 1. The connection points are pressed with fold lines to facilitate precise folding. The two symmetrically arranged first folding areas 2 and second folding areas 3 can be folded simultaneously to form a symmetrical outer wall structure, ensuring that the overall force on the pallet is balanced.

[0026] Please see Figure 1 , Figure 3 The second folding area 3 has a sliding hole, and a handle 13 that can slide along the sliding hole is inserted through the sliding hole. The handle 13 is made of plastic and is slidably connected to the second folding area 3, which improves the ease of handling without affecting the strength of the folding structure.

[0027] Please see Figure 1 , Figure 2 The fourth folding area 4 is fixedly connected to the side of the second folding area 3 away from the cardboard 1, and the connection position is pressed with a fold line. The fourth folding area 4 is also provided with a first positioning hole 11 that matches the shape of the first card plate 10, so that the first card plate 10 can be tightly inserted after folding, so as to realize the stable locking of the second folding area 3 and the sixth folding area 7, and prevent the outer wall from loosening and shifting when squeezed laterally.

[0028] Please see Figure 1 , Figure 2 The second plate 6 is fixedly connected to the fifth folding area 5. The fifth folding area 5 and the fourth folding area 4 are integrally fixedly connected on the side away from the second folding area 3, and each connection position is pressed with a fold line. After folding, the fifth folding area 5 can be perpendicular to the fourth folding area 4 to form a vertical support section of the inner wall.

[0029] Please see Figure 1 , Figure 3 A second positioning hole 12 is provided on the cardboard 1 at the position corresponding to the folding trajectory of the second card plate 6. After the second card plate 6 is folded inward along with the fifth folding area 5, it can be tightly inserted into the second positioning hole 12. Through the cooperation between the second card plate 6 and the second positioning hole 12, the fifth folding area 5 of the inner wall is firmly connected to the main body of the cardboard 1, ensuring that the relative position of the inner wall and the outer wall is fixed.

[0030] Please see Figure 2 , Figure 4The sixth folding area 7 and the first card plate 10 are both fixedly connected to the side of the first folding area 2 away from the cardboard 1, and the connection positions are pressed with fold lines to facilitate folding. The seventh folding area 8 is integrally fixedly connected to the end of the sixth folding area 7 away from the first folding area 2. After folding, the sixth folding area 7 can be perpendicular to the first folding area 2, and the seventh folding area 8 can be perpendicular to the sixth folding area 7, forming a transverse support section of the inner wall.

[0031] Please see Figure 4 , Figure 5 The seventh folding area 8 has a third positioning hole 14 and a fold line on the third card plate 15. After folding, it can be tightly inserted into the third positioning hole 14. The third folding area 9 is integrally fixedly connected to the side of the seventh folding area 8 away from the sixth folding area 7. After folding, it can work with the seventh folding area 8 to enhance the inner wall strength. After the third card plate 15 is inserted, it forms a support member perpendicular to the inner wall, which greatly improves the side's resistance to compression deformation.

[0032] The implementation principle of a paper pallet to prevent deformation by compression in this application embodiment is as follows: the first folding area 2 and the second folding area 3 are folded vertically along the fold line; the fourth folding area 4 is folded synchronously with the second folding area 3; the sixth folding area 7 is folded vertically along the fold line with the first folding area 2, together forming the outer wall of the paper pallet; the fifth folding area 5 is folded inward along the fold line with the fourth folding area 4; the seventh folding area 8 is folded inward along the fold line with the sixth folding area 7; the third folding area 9 is folded synchronously with the seventh folding area 8, together forming the inner wall of the paper pallet, forming a double-layer protective structure with the outer wall; the first pallet 10 is folded inward along the sixth folding area 2. After folding, the folding area 7 is inserted into the first positioning hole 11 of the fourth folding area 4 to complete the precise locking of each folding area of ​​the outer wall and prevent the outer wall from loosening and shifting under force. After folding along with the fifth folding area 5, the second cardboard 6 is inserted into the second positioning hole 12 on the cardboard 1 to achieve a stable connection between the inner wall and the main body of the cardboard 1. After folding along its own fold line, the third cardboard 15 is inserted into the third positioning hole 14 of the seventh folding area 8 to form a support member perpendicular to the inner wall. It directly applies an upward supporting force to the seventh folding area 8 and the fifth folding area 5, fills the weak points of the inner wall after folding, and significantly improves the overall compression resistance.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
