Abstract
Description
Technical Field
[0001] This utility model relates to the field of freight pallet technology, specifically a lightweight air freight pallet. Background Technology
[0002] A freight pallet is a horizontal platform device used for the containerization, stacking, handling, and transportation of goods and products as unit loads. Pallets are an indispensable tool in logistics and transportation, enabling the transformation of static goods into dynamic goods, greatly improving the efficiency and flexibility of logistics operations. Traditional freight pallets are generally assembled from wood or composite materials, or injection molded from thermoplastic materials. All of these pallets are relatively heavy. However, in the air freight industry, in order to transport more goods, it is necessary to reduce the weight of freight pallets. Therefore, traditional freight pallets are not suitable for air freight. To improve this situation, a lightweight air freight pallet is proposed.
[0003] A lightweight pallet, disclosed in authorization announcement number CN217554484U, includes a base plate, a plurality of support feet are provided on the bottom surface of the base plate, and a forklift arm insertion channel is formed between adjacent support feet. Weight reduction structures are provided on both the base plate and the support feet.
[0004] While the weight-reduction structure on the base plate and support legs of this pallet makes it lighter, reduces manual labor intensity, decreases the energy consumption of lifting equipment, and also improves the load-bearing capacity of the pallet, the positioning chip embedded in the support legs of this pallet enables the pallet to have signal exchange capabilities, allowing relevant personnel to obtain information such as the pallet's position and transfer location in a timely manner.
[0005] However, this does not solve the problem that existing freight pallets are not easy to splice and adjust to fit goods of different sizes, are not good at providing side protection for goods, and affect the stability during use. Utility Model Content
[0006] The purpose of this utility model is to provide a lightweight air cargo pallet to solve the problems mentioned in the background art, such as the inconvenience of cargo pallets in terms of easy splicing and adjustment to adapt to goods of different sizes, the difficulty in providing side protection for goods, and the impact on stability during use.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a lightweight air cargo pallet, comprising a base frame and support legs. The base frame consists of multiple sets, with two sets of support legs installed at each end of the base frame. T-slots and T-blocks are symmetrically installed on both sides of the base frame, and the T-blocks are slidably connected to the T-slots. Locking pins are installed on the side walls of the T-slots, and the locking pins penetrate the T-slots and T-blocks.
[0008] Preferably, an integrated frame is installed at the middle position of the bottom end of the base frame, and a folding rod is provided inside the support leg.
[0009] Preferably, the folding rod is slidably connected to the support leg, and two sets of connecting rods are installed between the two sets of folding rods.
[0010] Preferably, each of the support legs has symmetrically arranged sliding grooves on its outer wall, and bolt assemblies are slidably installed inside each of the sliding grooves.
[0011] Preferably, the bolt assembly passes through the support leg and the folding rod, and a notch is provided on the side wall of the support leg on one side of the folding rod.
[0012] Preferably, each of the integrated frames is provided with a bidirectional lead screw, and the bidirectional lead screw is movably connected to the integrated frame.
[0013] Preferably, the surface of the bidirectional lead screw is fitted with two sets of threaded sleeves, and the threaded sleeves are threadedly connected to the bidirectional lead screw, and the threaded sleeves are slidably connected to the integrated frame.
[0014] Preferably, each threaded sleeve is provided with a linkage arm at its bottom end, and each linkage arm is provided with a pin at the end near the threaded sleeve, and the linkage arm is movably connected to the threaded sleeve through the pin.
[0015] Preferably, each of the connecting arms is provided with a support arm at the end away from the pin, and each of the support arms is provided with a hinge shaft on the side of the connecting arm close to the connecting arm, and the support arm is movably connected to the connecting arm through the hinge shaft.
[0016] Preferably, each of the support arms is provided with a linkage shaft at one end near the integrated frame, and the support arm is movably connected to the integrated frame through the linkage shaft.
[0017] Compared with the prior art, the beneficial effects of this utility model are: the freight pallet not only realizes convenient splicing and adjustment to adapt to goods of different sizes and facilitates side protection of goods, but also improves the stability during use.
[0018] By aligning the T-block with the T-slot and inserting it into the T-slot, then inserting and locking the locking pin into the T-slot and T-block, the T-slot and T-block are fixedly connected, and two sets of base frames are spliced together. Multiple sets of base frames can then be spliced together using the above operations. Splicing multiple sets of base frames increases structural strength and allows for a larger base frame area to accommodate more goods. Before placing goods, the folding rod and connecting rod are folded. Rotating the folding rod causes the connecting rod to rotate around the bolt assembly as an axis. The folding rod rotates within the notch, thus folding the rod... The device transitions from a folded to an unfolded state. After releasing the folding rod, gravity causes the bolt assembly to slide within the groove. When the bolt assembly reaches the bottom of the groove, it is tightened to secure the folding rod to the support leg. This allows the folding rod and connecting rod to form a "side railing" to protect the goods. When not in use, the process can be repeated to fold the folding rod and connecting rod to the surface of the base frame for storage, reducing space occupation. This allows for convenient splicing and adjustment to accommodate goods of different sizes, facilitating side protection of the goods.
[0019] By rotating the double-acting screw, the two sets of threaded sleeves move away from each other. The threaded sleeves drive the linkage arm to rotate via a pin. The linkage arm then drives the support arm to rotate around the linkage shaft via a hinge shaft. The integrated frame provides movable support for the support arm, allowing it to contact the ground. This provides an upward support force to the middle of the base frame, preventing excessive pressure and deformation of the middle part of the base frame. It also improves the stability of the pallet during use and extends its service life. This provides stable support for the pallet, prevents it from deforming under pressure, improves stability during use, and extends the pallet's service life. Attached Figure Description

[0029] Example 1
[0030] Please see Figure 1-5The present invention provides an embodiment of a lightweight air cargo pallet, comprising a base frame 1 and support legs 4. The base frame 1 is in multiple sets, with two sets of support legs 4 installed at both ends of the base frame 1. T-slots 3 and T-blocks 6 are symmetrically installed on both sides of the base frame 1, and the T-blocks 6 are slidably connected to the T-slots 3. Locking pins 8 are installed on the side walls of the T-slots 3, and the locking pins 8 penetrate the T-slots 3 and the T-blocks 6. An integrated frame 2 is installed at the middle position of the bottom end of the base frame 1. Folding rods 5 are provided inside the support legs 4, and the folding rods 5 are slidably connected to the support legs 4. Two sets of connecting rods 7 are installed between the two sets of folding rods 5. Sliding grooves 17 are symmetrically provided on the outer walls of the support legs 4. Bolt assemblies 16 are slidably installed inside the sliding grooves 17, and the bolt assemblies 16 penetrate the support legs 4 and the folding rods 5. Notches 18 are provided on the side walls of the support legs 4 on one side of the folding rods 5.
[0031] Align T-block 6 with T-slot 3 and insert it into T-slot 3. Then, insert locking pin 8 into T-slot 3 and T-block 6 and lock them in place to secure T-slot 3 and T-block 6 together, thus connecting the two sets of base frames 1. The above operations are then used to complete the interlocking of multiple sets of base frames 1. Interlocking multiple sets of base frames 1 increases structural rigidity and allows for a larger area of base frames 1 to accommodate more goods. Before placing goods, folding rod 5 and connecting rod 7 are folded. Rotating folding rod 5 causes connecting rod 7 to rotate around bolt assembly 16. Folding rod 5 rotates within notch 18 to fold... The rod 5 changes from a folded state to an unfolded state. After the folding rod 5 is released, under the action of gravity, the folding rod 5 drives the bolt assembly 16 to slide inside the slide groove 17. When the bolt assembly 16 moves to the bottom of the slide groove 17, the bolt assembly 16 is locked to fix the folding rod 5 to the support leg 4. This allows the folding rod 5 and the connecting rod 7 to form a "side guardrail" to protect the goods. When not in use, the above operation can be repeated in reverse to fold the folding rod 5 and the connecting rod 7 to the surface of the base frame 1 for folding and storage, reducing space occupation and realizing convenient splicing and adjustment to adapt to goods of different sizes, which facilitates side protection of goods.
[0032] The integrated frame 2 is equipped with a bidirectional lead screw 9 inside, and the bidirectional lead screw 9 is movably connected to the integrated frame 2;
[0033] Two sets of threaded sleeves 10 are fitted on the surface of the bidirectional lead screw 9, and the threaded sleeves 10 are threadedly connected to the bidirectional lead screw 9. The threaded sleeves 10 are slidably connected to the integrated frame 2. The bottom end of each threaded sleeve 10 is provided with a linkage arm 12. The end of each linkage arm 12 near the threaded sleeve 10 is provided with a pin 11, and the linkage arm 12 is movably connected to the threaded sleeve 10 through the pin 11.
[0034] Each of the two ends of the linkage arm 12 away from the pin 11 is provided with a support arm 14. Each of the two supports is provided with a hinge shaft 13 on the side of the support arm 14 close to the linkage arm 12. The support arm 14 is movably connected to the linkage arm 12 through the hinge shaft 13. Each of the two ends of the support arm 14 close to the integrated frame 2 is provided with a linkage shaft 15. The support arm 14 is movably connected to the integrated frame 2 through the linkage shaft 15.
[0035] Rotating the bidirectional lead screw 9, with the threaded connection between the threaded sleeve 10 and the bidirectional lead screw 9, the bidirectional lead screw 9 drives the two sets of threaded sleeves 10 to move away from each other. The threaded sleeves 10 drive the linkage arm 12 to rotate through the pin 11. The linkage arm 12 drives the support arm 14 to rotate around the linkage shaft 15 through the hinge shaft 13. The integrated frame 2 provides movable support for the support arm 14, so that the support arm 14 contacts the ground, thereby providing an upward support force to the middle part of the base frame 1 to prevent the middle part of the base frame 1 from being deformed due to excessive pressure. It can also improve the stability of the pallet in use and extend its service life. It facilitates the provision of stable support for the pallet, prevents the pallet from being deformed under pressure, improves the stability during use, and extends the service life of the pallet.
[0036] Work steps
[0037] Working principle: Align T-block 6 with T-slot 3, insert T-block 6 into the interior of T-slot 3, then insert locking pin 8 into the interior of T-slot 3 and T-block 6 and lock it to fix T-slot 3 and T-block 6 together, splicing two sets of base frames 1 together. Then, through the above operation, multiple sets of base frames 1 can be spliced together. The splicing of multiple sets of base frames 1 increases the structural strength and increases the area of base frames 1 to accommodate more goods. Before placing goods, folding rod 5 and connecting rod 7 are folded. Rotating folding rod 5 causes connecting rod 7 to rotate around bolt assembly 16. Folding rod 5 rotates inside notch 18, changing from a folded state to an unfolded state. Then, releasing folding rod 5, under the action of gravity, folding rod 5 causes bolt assembly 16 to slide inside slide groove 17. When bolt assembly 16 moves to the bottom of slide groove 17, locking bolt assembly 16 is performed to fix folding rod 5 and connecting rod 7. The support leg 4 is fixedly connected, thereby forming a "side guardrail" with the folding rod 5 and the connecting rod 7 to protect the goods. When not in use, the above operation can be repeated in reverse to fold the folding rod 5 and the connecting rod 7 to the surface of the base frame 1 for storage, reducing space occupation. Rotating the double-acting screw 9, with the threaded connection between the threaded sleeve 10 and the double-acting screw 9, the double-acting screw 9 drives the two sets of threaded sleeves 10 to move away from each other. The threaded sleeve 10 drives the linkage arm 12 to rotate through the pin 11. The linkage arm 12 drives the support arm 14 to rotate around the linkage shaft 15 through the hinge shaft 13. The integrated frame 2 provides movable support for the support arm 14, so that the support arm 14 contacts the ground, thereby providing an upward support force to the middle of the base frame 1 to prevent the middle part of the base frame 1 from being deformed due to excessive pressure. It can also improve the stability of the pallet in use and extend its service life. The above is the complete usage of the lightweight air cargo pallet.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
