Description

Technical Field

[0001] This application relates to the field of logistics and transportation technology, and in particular to a collapsible pallet. Background Technology

[0002] In the aluminum and steel supply chain, products are usually transported on pallets. Traditional pallets are mostly fixed and cannot be adjusted according to the size of the product. For some larger coil products, the fixed traditional pallets cannot meet the transportation needs due to the change in product size, so larger pallets need to be customized, which increases transportation costs. After the products are transported, the storage of pallets of different sizes is also more troublesome. Pallets of different sizes cannot be stacked reasonably, which is not convenient for pallet recycling after transportation. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this application is to provide a foldable tray to solve the problem that traditional trays in the prior art cannot be adjusted according to the size of the product.

[0004] To achieve the above and other related objectives, this application provides a foldable tray, comprising:

[0005] The pallet section includes a bracket and a pallet body, the pallet body covering the bracket, and the pallet body having notches on both sides;

[0006] An extension portion is movably connected to the bracket, and the extension portion is movable relative to the tray body on the bracket to expand the tray body or to accommodate the extension portion in a notch in the tray body.

[0007] Optionally, the bracket includes multiple support beams and connecting beams, with connecting beams provided between adjacent support beams.

[0008] Optionally, the bracket has a groove on the support beam near the notch. The extension includes a support frame and an extension disc. The extension disc is disposed on the support frame. Positioning pins are provided on both sides of the support frame. The support frame is engaged in the groove by the positioning pins. The positioning pins can move on the groove to drive the support frame to move relative to the tray body on the bracket. The support frame moves toward the tray body to house the extension disc at the notch of the tray body. The support frame moves away from the tray body to open the extension disc and extend the tray body.

[0009] Optionally, the support frame is provided with two guide beams in the middle, and the guide beams extend at least partially from one side of the support frame toward the tray body. The guide beams are spaced apart, and the space forms a guide position that cooperates with the support beam in the middle of the tray. The support beam in the middle of the tray extends into the guide position to guide the movement of the support frame.

[0010] Optionally, a roller is provided between the extended portion of the guide beam and the support beam in the middle of the bracket, and the roller can roll on the support beam in the middle of the bracket when the support frame moves.

[0011] Optionally, the bracket is provided with a positioning part and a limiting groove on both sides near the notch. The positioning part includes at least two positioning beams, which are arranged opposite to each other on both sides of the expansion part. One end of the positioning beam is movably connected to the limiting groove of the bracket, and the other end of the positioning beam is a free end. The free end of the positioning beam can perform circumferential movement relative to the bracket. When the expansion disk is opened, the free end of the positioning beam is moved to abut against both sides of the support frame to position the expansion disk. When the expansion disk is retracted, the free end of the positioning beam is moved to retract the positioning beam to the limiting groove. The positioning beam at least partially blocks the movement direction of the expansion disk to limit the movement of the expansion disk.

[0012] Optionally, the support frame has a mounting beam on the side away from the pallet body. Both ends of the mounting beam have extension beams extending from both sides of the support frame. The mounting beam has a locking groove, and the locking groove has a locking structure. The locking structure includes a locking rod and an elastic element. The locking rod passes through the extension beam along its length and extends from the end of the extension beam near the positioning rod. The locking rod has an L-shaped structure. The elastic element passes through the locking rod and abuts against the crossbar of the locking rod and the extension beam. The free end of the positioning beam has a mounting hole, and the locking rod extends from the extension beam and passes through the mounting hole to connect the positioning beam to the support frame.

[0013] Optionally, the pallet body is further provided with a clearance opening that matches the extension beam, and the clearance opening communicates with the notch.

[0014] Optionally, the positioning beam is further provided with a positioning plate, the positioning plate having a positioning hole, the bracket being provided with a positioning post on the clearance opening, the positioning post having a positioning ball, and a limiting plate being provided above the positioning ball. When the free end of the positioning beam moves to the limiting groove, the positioning plate extends between the positioning ball and the limiting plate, and the positioning ball is engaged between the positioning holes to position the positioning beam on the limiting groove.

[0015] Optionally, the expansion disk has an adjustment window for adjusting the locking lever and a guide port that matches the guide position.

[0016] In the collapsible pallet provided in this application, the extension is housed in the notch of the pallet body. When transporting smaller or conventional roll products, the size of the pallet body is sufficient to meet the transport requirements of such products. When transporting larger products, the extension can be moved to open it, thereby expanding the size of the pallet body to meet the transport requirements of larger products. This allows one pallet to meet the transport requirements of products of various sizes, and it can be adjusted according to the product size. After the products are transported, the extension can be neatly stored, facilitating pallet stacking and subsequent recycling. Attached Figure Description

[0026] Please see Figures 1 to 5 This application provides, by way of example, a foldable tray, comprising:

[0027] The pallet section includes a bracket 2 and a pallet body 1, the pallet body 1 covering the bracket 2, and the pallet body 1 having notches 14 on both sides;

[0028] The extension is movably connected to the bracket 2. The extension can move relative to the tray body 1 on the bracket 2 to expand the tray body 1 or to store the extension in the notch 14 of the tray body 1.

[0029] In the collapsible pallet provided in this application, the extension is housed in the notch 14 of the pallet body 1. When transporting smaller or conventional roll products, the size of the pallet body 1 can meet the transportation needs of such products. When transporting larger products, the extension can be moved to open the extension, thereby expanding the size of the pallet body 1 to meet the transportation needs of larger products. This allows one pallet to meet the transportation needs of products of various sizes. It can be adjusted according to the product size. After the product is transported, the extension can be stored in a unified manner, which is convenient for pallet stacking and subsequent recycling.

[0030] In this embodiment, the bracket 2 includes multiple support beams 16 and connecting beams 17. A connecting beam 17 is provided between adjacent support beams 16. Specifically, the notch 14 is opened in the middle of both sides of the pallet body 1. The notch 14 of the pallet body 1 is supported by the three support beams 16 in the middle of the bracket 2. The connecting beam 17 connects the support beams 16 along the long side of the notch 14. The support beams 16 and connecting beams 17 enhance the load-bearing strength of the pallet body 1. At the same time, corresponding support beams 16 and connecting beams 17 are provided on the three sides of the notch 14 to enhance the strength of the pallet body 1 at the notch 14.

[0031] In the above embodiment, the bracket 2 has a groove 27 on the support beam 16 near the notch 14. The extension part includes a support frame 4 and an extension disk 3. The extension disk 3 is disposed on the support frame 4. Positioning pins 28 are provided on both sides of the support frame 4. The support frame 4 is engaged with the groove 27 by the positioning pins 28. The positioning pins 28 can move on the groove 27 to drive the support frame 4 to move relative to the tray body 1 on the bracket 2. The support frame 4 moves towards the tray body 1 to house the extension disk 3 at the notch 14 of the tray body 1. The support frame 4 moves away from the tray body 1 to open the extension disk 3 and expand the tray body 1. Specifically, the groove 27 has a first straight section and an inclined section. The pallet 3 is divided into two sections. The horizontal height of the second straight section is lower than that of the first straight section. When storing the expansion tray 3, the positioning pin 28 moves from the first straight section to the inclined section on the slide 27, and then passes through the second straight section to complete the storage of the expansion tray 3. At this time, the horizontal height of the expansion tray 3 is lower than that of the pallet body 1, so as to avoid collision and damage between the expansion parts of adjacent pallets when the pallets are stacked. When opening the expansion tray 3, the positioning pin 28 moves from the second straight section to the inclined section on the slide 27, and then passes through the first straight section to complete the opening of the expansion tray 3. At this time, the expansion tray 3 is aligned with the pallet body 1 in terms of horizontal height, so that after the expansion tray 3 expands the pallet body 1, it can cooperate with the pallet body 1 to support and transport larger products.

[0032] In some embodiments, two guide beams 10 are provided in the middle of the support frame 4. The guide beams 10 extend at least partially from one side of the support frame 4 toward the tray body 1. There is a gap between the guide beams 10, which forms a guide position that cooperates with the support beam 16 in the middle of the bracket 2. The support beam 16 in the middle of the bracket 2 extends into the guide position to guide the movement of the support frame 4. Specifically, a roller 22 is provided between the extended part of the guide beam 10 and the support beam 16 in the middle of the bracket 2. When the support frame 4 moves, the roller 22 can roll on the support beam 16 in the middle of the bracket 2. The cooperation between the guide position and the support beam 16 in the middle of the bracket 2 facilitates the positioning and installation of the support frame 4. At the same time, during the movement of the support frame 4 on the slide 27, the guide position can guide the movement of the support frame 4, improve the folding effect of the extension. The roller 22 reduces the friction between the guide beam 10 and the support beam 16 in the middle of the bracket 2, which facilitates the opening or closing operation of the extension.

[0033] In this embodiment, the bracket 2 is provided with a positioning part and a limiting groove 6 on both sides near the notch 14. The positioning part includes at least two positioning beams 5, which are arranged opposite to each other on both sides of the expansion part. One end of the positioning beam 5 is movably connected to the limiting groove 6 of the bracket 2, and the other end of the positioning beam 5 is a free end. The free end of the positioning beam 5 can move in a circular motion relative to the bracket 2. When the expansion disk 3 is opened, the free end of the positioning beam 5 is moved to abut against both sides of the support frame 4 to position the expansion disk 3. When the expansion disk 3 is stored, the free end of the positioning beam 5 is moved to retract the positioning beam 5 to the limiting groove 6. The positioning beam 5 at least partially blocks the movement direction of the expansion disk 3 to limit the expansion disk 3. Specifically, a positioning shaft 7 is provided on the limiting groove 6, and one end of the positioning beam 5 is rotatably connected to the positioning shaft 7. The positioning beam 5 can move in a circular motion in the limiting groove 6 with the positioning shaft 7 as the center.

[0034] In the above embodiment, the support frame 4 has a mounting beam 18 on the side away from the pallet body 1. Extension beams 19 extending from both sides of the support frame 4 are provided at both ends of the mounting beam 18. A locking groove 21 is provided on the mounting beam 18, and a locking structure is provided on the locking groove 21. The locking structure includes a locking rod 20 and an elastic element 26. The locking rod 20 passes through the extension beam 19 along its length and extends from the end of the extension beam 19 near the positioning rod. The locking rod 20 is L-shaped. The elastic element 26 passes through the locking rod 20 and abuts against the crossbar of the locking rod 20 and the extension beam 19. A mounting hole 29 is provided at the free end of the positioning beam 5. The locking rod 20 extends from the extension beam 19 and passes through the mounting hole 29 to connect the positioning beam 5 to the support frame 4. Specifically, the locking grooves 21 are located near both sides of the mounting beam 18. Two locking grooves 21 are provided on each side of the mounting beam 18, and the two locking grooves 21 are located adjacent to each other on the mounting beam 18. On both sides, one locking groove 21 is longer than the other locking groove 21. When the expansion disk 3 is opened, the positioning beam 5 abuts against the two sides of the support frame 4, so that the horizontal bar of the locking rod 20 is located on the shorter locking groove 21. The vertical bar of the locking rod 20 passes through the extension beam 19 and extends into the mounting hole 29. Since the locking groove 21 is shorter, the elastic element 26 is in a compressed state at this time, which abuts the horizontal bar of the locking rod 20 against the locking groove 21, completing the limiting of the locking rod 20, ensuring the stable connection between the positioning beam 5 and the support frame 4, and preventing the expansion disk 3 from shifting during the support and transportation process. When the expansion disk 3 is stored, the locking rod 20 is rotated at a certain angle, so that the horizontal bar of the locking rod 20 moves to the longer locking groove 21. At this time, the elastic element 26 is no longer constrained and is stretched, pushing the horizontal bar of the locking rod 20 towards the locking groove 21, so that the locking rod 20 exits the mounting hole 29, thereby releasing the connection between the positioning beam 5 and the support frame 4.

[0035] In some embodiments, the tray body 1 is also provided with a clearance opening 13 that matches the extension beam 19. The clearance opening 13 is connected to the notch 14. The overall appearance of the notch 14 is adjusted by the clearance opening 13 so that the extension tray 3 matches the notch 14 better after being stored, thereby improving the appearance after storage.

[0036] In this embodiment, a positioning plate 8 is also provided on the positioning beam 5, and a positioning hole 9 is provided on the positioning plate 8. A positioning post 23 is also provided on the bracket 2 at the clearance opening 13, and a positioning ball 24 is provided on the positioning post 23. A limiting plate 25 is provided above the positioning ball 24. When the free end of the positioning beam 5 moves to the limiting groove 6, the positioning plate 8 extends between the positioning ball 24 and the limiting plate 25, and the positioning ball 24 is engaged in the positioning hole 9 to position the positioning beam 5 in the limiting groove 6. Specifically, an elastic element 26 passes through the positioning post 23, and the positioning ball 24 is connected to the elastic element 26 and can move axially on the positioning post 23. When the positioning ball 24 does not compress the elastic element 26... The positioning ball 24 extends at least partially from the end face of the positioning post 23. When storing the expansion tray 3, the expansion tray 3 is first moved to the notch 14, and the positioning beam 5 is moved to the limiting groove 6. At this time, the positioning plate 8 extends between the positioning ball 24 and the limiting plate 25. The positioning plate 8 squeezes the positioning ball 24, and the positioning ball 24 compresses the spring until the positioning ball 24 is locked in the positioning hole 9. The spring extends and retracts to press the positioning ball 24 against the positioning hole 9, thereby positioning the positioning beam 5 in the limiting groove 6. At this time, the positioning beam 5 at least partially blocks the movement direction of the expansion tray 3, limiting the storage of the expansion tray 3 and preventing the expansion tray 3 from expanding on its own during transportation, which would cause damage to the pallet.

[0037] In the above embodiment, the expansion disk 3 is provided with an adjustment window 11 for adjusting the locking rod 20 and a guide port 12 that matches the guide position. The adjustment window 11 facilitates the adjustment of the position of the locking rod 20 to connect the positioning beam 5 and the support frame 4. The guide port 12 makes room for the support beam 16 in the middle of the bracket 2. After the expansion disk 3 is stored, the guide port 12 is filled by the support beam 16 in the middle of the bracket 2. With the notch 14 and the clearance port 13, the stored expansion disk 3 can match the notch 14, improving the appearance after storage.

[0038] In some embodiments, a base 15 is also provided at the bottom of the bracket 2. The base 15 enhances the load-bearing strength of the bracket 2. At the same time, during storage, the base 15 keeps the bracket 2 at a certain distance from the ground to prevent the ground from becoming contaminated or damp, which would affect the product performance.

[0039] In summary, in the collapsible pallet provided in this application, the extension is housed at the notch 14 of the pallet body 1. When transporting smaller or conventional roll products, the size of the pallet body 1 can meet the transportation needs of such products. When transporting larger products, the extension can be moved to open it, thereby expanding the size of the pallet body 1 to meet the transportation needs of larger products. This allows one pallet to meet the transportation needs of products of various sizes, and it can be adjusted according to the product size. After the product is transported, the extension can be neatly stored, facilitating pallet stacking and subsequent recycling.
