[0035] Example 1

[0036] As shown Figures 1 to 3As shown, this embodiment provides a heavy-duty pallet for air cargo, comprising a main toothed plate platform 1 and a secondary toothed plate platform 3. The exterior of the main toothed plate platform 1 engages with the exterior of the secondary toothed plate platform 3, forming the pallet's primary load-bearing structure. These two components slide stably relative to each other via opposing toothed plates in the middle, allowing the pallet's length to be adjusted to accommodate cargo of varying sizes. A slide bar 1 2 is fixedly connected to the bottom end of the main toothed plate platform 1, near the secondary toothed plate platform 3. Slide bar 1 2 is attached to the bottom end of the main toothed plate platform 1 to prevent the exterior of the main toothed plate platform 1 from disengaging from the secondary toothed plate platform 3.

[0037] The top of slide bar 1 (2) is slidably connected to the bottom of auxiliary tooth plate platform 3, and slide bar 1 (2) slides along the tooth plate portion of auxiliary tooth plate platform 3. The bottom of auxiliary tooth plate platform 3, close to the side of main tooth plate platform 1, is fixedly connected to slide bar 2 (4). The top of slide bar 2 (4) is slidably connected to the bottom of main tooth plate platform 1. Slide bar 2 (4) has the same function as slide bar 1 (2).

[0038] Example 2

[0039] like Figure 3 、 Figure 4 As shown, components identical or corresponding to those in Example 1 are denoted by the corresponding reference numerals. For simplicity, only the differences from Example 1 are described below. Example 2 differs from Example 1 in that a connector 5 is fixedly connected to the adjacent sides of slide bar 1 2 and slide bar 2 4. Connector 5 is used to connect and support the gear system. The front bottom end of connector 5 is rotatably connected to main sector gear rod 1 6, while the rear top end of connector 5 is rotatably connected to main sector gear rod 2 8. Main sector gear rod 1 6 and main sector gear rod 2 8 are the main components of the two large gear systems and are typically made of metal, offering high strength and wear resistance. They typically utilize gear meshing technology to transmit torque. Furthermore, the meshing of main sector gear rod 1 6 and main sector gear rod 2 8 controls the locking and deployment of the primary and secondary gear plate platforms 3. The end of the main sector gear rod 6 away from the connecting member 5 is rotatably connected to the slave sector gear rod 1 7, and the end of the main sector gear rod 2 8 away from the connecting member 5 is rotatably connected to the slave sector gear rod 2 9. The slave sector gear rod 1 7 and the slave sector gear rod 2 9 are the driven gear parts attached to the main gear rod and play a synchronization role.

[0040] The rear teeth of master sector gear rod 1 (6) mesh with the rear teeth of master sector gear rod 2 (8). Master sector gear rod 1 (6) and master sector gear rod 2 (8) mesh and rotate with support from connector 5. The rear teeth of slave sector gear rod 1 (7) mesh with the rear teeth of slave sector gear rod 2 (9). A connecting plate 10 is rotatably connected to the adjacent sides of the two slave sector gear rods 1 (7) and the two slave sector gear rods 2 (9). The slave sector gear rods 1 (7) and 2 (9) mesh with each other at four corners on connecting plate 10.

[0041] Example 3

[0042] like Figure 1 、 Figure 5 As shown, this embodiment provides a method for securing cargo. Two chutes 11 are defined at the top of the primary and secondary toothed pallets 1 and 3. Inside these chutes 11, an adjustment assembly is provided to assist in securing the cargo. The adjustment assembly includes a slider 12, the exterior of which slides slidably connected to the interior wall of the chutes 11. The chutes 11 are groove-shaped structures above the pallet that accommodate the sliders 12. The chutes 11 are typically made of a wear-resistant material to ensure that the sliders 12 slide smoothly within them without generating frictional resistance. The slider 12 is a sliding component typically made of plastic or metal.

[0043] The top of the slide 11 is fixedly connected to a locking ring 13, which is used to fix the fixing rope of the goods on the pallet. The locking ring is connected to the slider 12, so that the goods can be firmly fixed on the pallet to prevent sliding or displacement during transportation. The middle part of the slider 12 is slidably connected to a connecting rod 14, and the top of the connecting rod 14 is fixedly connected to a connecting shaft 15, and the outer ends of the connecting shaft 15 are fixedly connected to hook-type handles 16. The connecting rod 14 is a connector connecting the slider 12 and other operating components, usually made of metal, and is designed to withstand greater tension. The connecting shaft 15 is connected to the hook-type handle 16, and the outer side of the connecting shaft 15 is slidable and has an adjustment function. The hook-type handle 16 has an ascending and descending function, and is used to operate and control the locking and unlocking process.

[0044] The end of the hook handle 16 near the coupling 15 engages with the top of the slider 12. When the user rotates the hook handle 16, the protruding hook point on the outside contacts the slider 12, driving the tapered block 19 upward. Two through-slots 17 are defined on the side of the hook handle 16 near the slider 12. These slots 17 ensure stable rotation of the hook handle 16. The outer portion of the coupling 15 slides against the inner wall of the slots 17, and the sliding movement of the coupling 15 within the slots 17 defines the position of the hook handle 16. A spring 18 is mounted on the outside of the connecting rod 14. The hook handle 16 drives the tapered block 19 upward, compressing the spring 18. The top end of the spring 18 is fixedly connected to the inner wall of the slider 12, while the bottom end of the spring 18 is fixedly connected to the top of the tapered block 19, ensuring stable compression of the spring 18. The bottom end of the connecting rod 14 is fixedly connected to a conical block 19, and the inner bottom end of the slider 12 is slidably connected to two bevel sleeves 20. The conical block 19 and the bevel sleeve 20 are important parts of the tray locking mechanism. The conical block 19 is usually conical in design, and the bevel sleeve 20 is a sleeve structure with inner and outer bevels.

[0045] The outer portion of the conical block 19 is slidably connected to the adjacent sides of the two beveled sleeves 20. The beveled sleeves 20 slide on the inclined surface of the outer portion of the conical block 19. A clamping roller 21 is fixedly connected to the distal sides of the two beveled sleeves 20, which drive the clamping roller 21 to extend and retract. The outer portion of the clamping roller 21 engages with the inner wall of the chute 11, and the clamping roller 21 engages with various holes within the chute 11 to secure the position of the chute 13. A second spring 22 is mounted on the outer portion of the clamping roller 21. The end of the spring 22 facing away from the conical block 19 is fixedly connected to the inner wall of the slider 12, while the end of the spring 22 facing the conical block 19 is fixedly connected to the side of the beveled sleeve 20 facing away from the conical block 19. Supported by the inner wall of the slider 12, the spring 22 uses its elastic force to reposition the beveled sleeve 20.

[0046] Working steps

[0047] Step 1. First, according to the size of the cargo to be carried, pull the main gear plate 1 and the auxiliary gear plate 3, so that the slide bar 1 2 fixed to the main gear plate 1 and the slide bar 2 4 fixed to the auxiliary gear plate 3 slide relative to each other, and cooperate with the slide bar 2 4 and the slide bar 1 2 to rotate in the front and rear positions on the opposite sides of the main sector gear rod 1 6 and the main sector gear rod 2 8 to rotate and engage with each other, and synchronously allow the slave sector gear rod 1 7 connected to the main sector gear rod 1 6 and the slave sector gear rod 2 8 to rotate and engage at the four corners of the connecting plate 10, thereby increasing the resistance of the main gear plate 1 and the auxiliary gear plate 3 when they are unfolded, so that the main gear plate 1 and the auxiliary gear plate 3 can be unfolded to any length and locked to prevent the main gear plate 1 and the auxiliary gear plate 3 from shaking and becoming unstable.

[0048] Step 2. After the lengths of the main tooth plate 1 and the auxiliary tooth plate 3 are adjusted, the user can place the goods on the pallet, and then turn the hook handles 16 on both sides of the main tooth plate 1 and the auxiliary tooth plate 3 upward. After the hook handle 16 is rotated, the hook handle 16 will press against the top of the slider 12 through the external protruding hook point, pulling the conical block 19 to squeeze the spring 18 upward. At this time, due to the upward movement of the conical block 19 and the state of squeezing the inclined sleeve 20 when the conical block 19 is pressed down, when the conical block 19 slides upward, the squeezed spring 22 will be supported by the inner wall of the slider 12 through its own elastic force, driving the card roller 21 engaged with the slide groove 11 to retract into the slider 12. The position of the unlocking lock ring 13 is achieved, so that the user can pull the lock ring 13 to drive the slider 12 to tilt and fit the outside of the goods, and finally bend the hook handle 16 downward to release the force pulling on the connecting rod 14, so that the connecting rod 14 drives the conical block 19 downward to squeeze the inclined sleeve 20 through the spring 18. After the inclined sleeve 20 is squeezed, it pushes the card roller 21 to protrude outward and engage with the slide groove 11 to achieve locking, which makes it convenient for the user to fix the ropes for fixing the goods to fit the goods through the lock rings 13 at the four corners of the pallet, thereby increasing the firmness of the ropes.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
