[0002] A pallet is a flat structure used for transporting and storing goods, typically made of wood, plastic, or metal. It provides a stable surface, allowing items to be easily handled by forklifts, lifts, or manually.
[0003] A collapsible pallet is a type of pallet designed with a folding function. Its main feature is that it can be folded up when not in use to save storage space and reduce transportation costs. When idle, a collapsible pallet can greatly reduce the space it occupies, which helps to save storage and transportation costs in warehouses or during transportation. When in use, the pallet can be expanded to accommodate the number of equipment used.
[0004] However, most pallets cannot be folded or unfolded during use, and are usually stacked for loading and unloading. This leads to unstable connections between multiple layers during use, which may cause them to collapse or tilt, and they are also inconvenient to move after being placed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a foldable tray, which aims to improve the problem that the connection between multiple layers is unstable during use, which may lead to collapse and tilting, and that it is inconvenient to move after placement.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A foldable tray includes tray A, tray B slidably connected to the outer wall of tray A, a first limiting rod fixedly connected to the upper surfaces of trays B and A, a first placement groove formed on the inner wall of tray A, a first limiting slide rod fixedly connected to the outer walls of trays A and B, a bottom support slidably connected to the outer wall of the first limiting slide rod, a first limiting groove formed on the inner wall of the bottom support, the outer wall of the first limiting slide rod slidably connected to the inner wall of the first limiting groove, a lifting rod rotatably connected to the inner walls of trays A and B, a support rod slidably connected to the lower surface of tray A, a rotating rod rotatably connected to the inner wall of the support rod, a connecting block rotatably connected to the outer wall of the rotating rod, a second slide rod rotatably connected to the outer wall of the rotating rod, a rotating groove formed on the inner wall of the second slide rod, the outer wall of the connecting block rotatably connected to the inside of the rotating groove, the upper surface of the connecting block fixedly connected to the lower surface of tray A, and a limiting movement component provided on the inner wall of the second slide rod for adjusting and unfolding the tray.
[0008] Preferably, the limiting movement component includes a slide rail, the outer wall of which is slidably connected to the inner wall of the second slide rod, the outer wall of which is fixedly connected to the inner wall of the base, and baffles fixedly connected to both ends of the slide rail, the lower surface of which is fixedly connected to the inner wall of the base.
[0009] Preferably, the inner wall of disk B is provided with a placement groove, and disk C is slidably connected to the upper surface of the base.
[0010] Preferably, the front and rear outer walls of the C disk are fixedly connected with side supports, and the inner wall of the C disk is provided with a second limiting groove.
[0011] Preferably, the outer wall of the second limiting groove is slidably connected to the outer wall of the first limiting rod, and the lower surface of the side support is slidably connected to the upper surface of the support base.
[0012] Preferably, the inner wall of the C disk is slidably connected to a second placement groove.
[0013] Preferably, the outer wall of disk C is slidably connected to the inner wall of the slide rail.
[0014] Preferably, a second limiting rod is fixedly connected to the upper surface of the C disk, and the outer wall of the second limiting rod is slidably connected to the lower surface of another C disk.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, by holding the lifting rods on both sides and pulling them outward, the A and B discs open and unfold under the limitation of the first limiting slide rod and the first limiting groove. When the second slide rod slides on the outer wall of the slide rail to the limit of the baffle, the connecting block rotates under the limitation of the rotating groove and the rotating rod, which allows the A and B discs to unfold and load more materials.
[0017] 2. In this utility model, after the B disk is unfolded and flipped, the C disk slides into the upper surface of the bottom support through the limiting position of the placement groove, and is supported by the side support. During use, the first limiting rod and the second limiting groove play a limiting role during installation. During use, it can further prevent the pallet from collapsing and scattering, causing damage to the materials due to the lack of a limiting structure during transportation.
[0018] 3. In this utility model, the second limiting rod above the C disk slides into the groove at the bottom of another C disk, which can make the two C disks tightly connected during use to prevent them from separating. Moreover, the shape of the second placement groove in the C disk can be adjusted according to the shape of different materials, so that different materials can be stacked and transported during use.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Reference Figures 1-2This utility model provides an embodiment of a foldable tray, including tray A1, tray B2 slidably connected to the outer wall of tray A1, a first limiting rod 3 fixedly connected to the upper surface of tray B2 and tray A1, a first placement groove 4 formed on the inner wall of tray A1, a first limiting slide rod 8 fixedly connected to the outer walls of tray A1 and tray B2, a base 6 slidably connected to the outer wall of the first limiting slide rod 8, a first limiting groove 7 formed on the inner wall of the base 6, the outer wall of the first limiting slide rod 8 slidably connected to the inner wall of the first limiting groove 7, a lifting rod 5 rotatably connected to the inner walls of tray A1 and tray B2, a support rod 9 slidably connected to the lower surface of tray A1, and a rotating rod 11 rotatably connected to the inner wall of the support rod 9. A connecting block 12 is rotatably connected to the outer wall of the rotating rod 11, and a second sliding rod 13 is rotatably connected to the outer wall of the rotating rod 11. A rotating groove 10 is provided on the inner wall of the second sliding rod 13. The outer wall of the connecting block 12 is rotatably connected to the inside of the rotating groove 10. The upper surface of the connecting block 12 is fixedly connected to the lower surface of the A disk 1. A limiting movement component is provided on the inner wall of the second sliding rod 13. The limiting movement component is used to adjust and unfold the tray. The limiting movement component includes a slide rail 15. The outer wall of the slide rail 15 is slidably connected to the inner wall of the second sliding rod 13. The outer wall of the slide rail 15 is fixedly connected to the inner wall of the base 6. Baffles 14 are fixedly connected to both ends of the slide rail 15. The lower surface of the baffles 14 is fixedly connected to the inner wall of the base 6.
[0026] Specifically, by holding the two lifting rods 5 and pulling them outward, the A disk 1 and B disk 2 are opened under the limit of the first limiting slide rod 8 and the first limiting groove 7. When the second slide rod 13 slides on the outer wall of the slide rail 15 to the limit of the baffle 14, the connecting block 12 rotates under the limit of the rotating groove 10 and the rotating rod 11, which allows the A disk 1 and B disk 2 to be opened and transformed into two side baffles. The C disk 17 can be placed in the middle for stacking and storage, and can be used according to different material shapes and quantities.
[0027] Reference Figure 3 The inner wall of disk B2 is provided with a placement groove 16, and disk C17 is slidably connected to the upper surface of the base 6; side supports 20 are fixedly connected to the front and rear outer walls of disk C17, and a second limiting groove 21 is provided on the inner wall of disk C17; the outer wall of the second limiting groove 21 is slidably connected to the outer wall of the first limiting rod 3, and the lower surface of the side support 20 is slidably connected to the upper surface of the base 6.
[0028] Specifically, the C disk 17 slides under the limit of the placement groove 16, and the C disk 17 can be taken out and put in through the side support 20. The side support 20 can facilitate the placement and support during use, and the second limit groove 21 can keep the C disk 17 neat and flat when it is put in, and can better support the stacking to prevent it from collapsing.
[0029] Reference Figure 3 The inner wall of disk C17 is slidably connected to a second placement groove 19; the outer wall of disk C17 is slidably connected to the inner wall of slide rail 15; the upper surface of disk C17 is fixedly connected to a second limiting rod 18, and the outer wall of the second limiting rod 18 is slidably connected to the lower surface of another disk C17.
[0030] Specifically, after the lower C-disc 17 is placed, the upper C-disc 17 slides into the outer wall of the second limiting rod 18, which plays a supporting role during use. This prevents the multi-layered C-disc 17 from tilting and collapsing due to shaking, thus avoiding damage to the materials inside.
[0031] Working principle: When the device is needed, by holding the two lifting rods 5 and pulling them outward, it unfolds through disks A1 and B2 under the limitation of the first limiting slide rod 8 and the first limiting groove 7. During use, when the second slide rod 13 slides on the outer wall of the slide rail 15 to the limit of the baffle 14, the connecting block 12 rotates under the limitation of the rotating groove 10 and the rotating rod 11, allowing disks A1 and B2 to unfold and transform into two side baffles. During use, disk C17 can be placed in the middle for stacking and storage, facilitating handling. It can be used according to different material shapes and quantities. During use, after disk B2 unfolds and flips, disk C17 slides into the upper surface of the base 6 under the limitation of the placement groove 16 and is supported by the side support 20. During use, the first limiting rod 3 and the second limiting groove 21 provide a limiting effect during installation. To further prevent the pallet from collapsing and scattering during handling due to the lack of a limiting structure, thus avoiding damage to materials, the second limiting rod 18 above the C-disc 17 slides into the groove at the bottom of another C-disc 17 during use. This ensures a tight connection between the two C-discs 17, preventing them from detaching. Furthermore, the shape of the second placement groove 19 within the C-disc 17 can be modified to accommodate different material shapes, allowing for stacking and handling of various materials. This pallet not only allows the A-disc 1 and B-disc 2 to be unfolded and used to load more materials by rotating under the limiting of the connecting block 12 in the rotating groove 10 and rotating rod 11, but also provides a limiting effect during installation via the first limiting rod 3 and the second limiting groove 21. This further prevents the pallet from collapsing and scattering during handling due to the lack of a limiting structure, thus avoiding damage to materials.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
