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

[0002] Pallets, also known as stacks or pallets, are platform devices used for the containerization, stacking, handling, and transportation of goods and products as unit loads. As a type of containerization equipment similar to containers, pallets are now widely used in production, transportation, warehousing, and distribution.

[0003] Some existing composite pallets are not convenient for flexible height adjustment during actual use, which reduces the stability of the pallet body in various environments, affecting the safety and ease of handling when stacking goods. Furthermore, the pallet body is prone to slippage or tipping during forklift handling, resulting in reduced handling efficiency and safety hazards. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a composite tray.

[0005] The composite pallet provided in this application adopts the following technical solution: A composite pallet includes a pallet body, with multiple sets of symmetrical bases installed at the bottom of both ends and the bottom of the middle of the pallet body. A support adjustment mechanism is installed inside the bases installed at the bottom of both ends of the pallet body. I-shaped reinforcing ribs are fixedly connected between the side walls of the bases. A bottom plate is also connected to the bottom of the base. Anti-collision sleeves are installed at the four corners of the pallet body. A clamping assembly is also installed at the bottom of the pallet body.

[0006] Preferably, the support adjustment mechanism includes a movable block installed in the movable cavity inside the base, a first spring connected to the top of the movable block, the other end of the first spring connected to the top surface inside the movable cavity, and a support column installed at the bottom of the movable block, one end of the support column extending through a through hole opened on the base.

[0007] Preferably, a T-shaped support block is installed on the side wall of the movable block. The T-shaped support block slides in a groove opened on one side of the base. A symmetrical through hole is opened on one end side wall of the T-shaped support block. A movable rod is slidably installed inside the through hole. One end of the movable rod is connected to a pull block, and the other end of the movable rod is connected to a fixed insertion rod.

[0008] Preferably, a second spring is connected to one end of the fixed rod connecting seat. The second spring surrounds the outer wall of the movable rod, and the other end is connected to the side wall of the T-shaped support block. The other end of the fixed rod passes through the positioning hole opened on the side wall of the base and enters the corresponding positioning hole opened on the side wall of the movable block.

[0009] Preferably, the clamping assembly includes a bidirectional lead screw installed inside a symmetrical groove at the bottom of the tray body. One end of the bidirectional lead screw is connected to a bearing seat provided on the inner wall of the groove, and the other end of the bidirectional lead screw extends out of the groove and is connected to a rotating handle.

[0010] Preferably, the bidirectional lead screw is fitted with symmetrical movable seats, the bottom of the movable seats is fitted with an L-shaped connecting block, the other end of the L-shaped connecting block is connected to a clamping plate, and one side of the clamping plate is provided with anti-slip protrusions.

[0011] In summary, this application includes the following beneficial technical effects: This utility model is equipped with a support adjustment mechanism. When adjusting the height of the pallet body, by pulling the pull block, the movable rod squeezes the second spring, causing the fixed insert rod to disengage from the positioning hole, thus releasing the limit on the movable block. At this time, under the action of the first spring, the movable block drives the support column to move downward, thereby adjusting the height of the pallet body. After the adjustment is in place, the pull block is released, and under the action of the second spring, the fixed insert rod is pushed back into the corresponding positioning hole to achieve height fixation. The operation is simple, stable and reliable. When the ground is uneven, the level of the pallet body can be quickly adjusted by adjusting the support adjustment mechanism installed inside one of the bases, ensuring that the goods are placed stably and improving the stability of the pallet body in various environments. This utility model is equipped with a clamping component. By rotating the handle, the bidirectional lead screw is driven to rotate, which drives the two moving seats to move towards each other. This allows the clamping plate to effectively limit the fork teeth on the forklift, preventing the pallet from sliding laterally or falling off during transportation, improving handling efficiency and reducing safety hazards.

[0014] The following is in conjunction with the appendix Figure 1 —5 provides further detailed description of this application.

[0015] This application discloses a composite pallet, including a pallet body 1. Multiple sets of symmetrical bases 2 are installed at the bottom of both ends and the bottom of the middle of the pallet body 1. Support and adjustment mechanisms are installed inside the bases 2 installed at the bottom of both ends of the pallet body 1. I-shaped reinforcing ribs 3 are fixedly connected between the side walls of the bases 2. A bottom plate is also connected to the bottom of the bases 2. Anti-collision sleeves 4 are installed at the four corners of the pallet body 1. A clamping component is also installed at the bottom of the pallet body 1.

[0016] refer to Figure 3 and Figure 4 The support adjustment mechanism includes a movable block 5 installed in the movable cavity inside the base 2. A first spring 6 is connected to the top of the movable block 5, and the other end of the first spring 6 is connected to the top surface inside the movable cavity. A support column 7 is installed at the bottom of the movable block 5, and one end of the support column 7 passes through a through hole opened on the base 2. A T-shaped support block 8 is installed on the side wall of the movable block 5. The T-shaped support block 8 slides in a groove opened on one side of the base 2. A symmetrical through hole is opened on one side wall of the T-shaped support block 8, and a movable rod 9 is slidably installed inside the through hole. A pull block is connected to one end of the movable rod 9, and a fixed insertion rod 10 is connected to the other end of the movable rod 9. A second spring 11 is connected to a connecting seat at one end of the fixed insertion rod 10. The second spring 11 surrounds the outer wall of the movable rod 9, and the other end is connected to the side wall of the T-shaped support block 8. The other end of the fixed insertion rod 10 passes through a groove opened on the side wall of the base 2. The positioning hole 12 is inserted into the corresponding positioning hole 12 on the side wall of the movable block 5. More specifically, when adjusting the height of the pallet body 1, the pull block is pulled, causing the movable rod 9 to squeeze the second spring 11 and drive the fixed insertion rod 10 to disengage from the positioning hole 12, thus releasing the limitation on the movable block 5. At this time, under the action of the first spring 6, the movable block 5 is driven to move downward, causing the support column 7 to move downward, thereby adjusting the height of the pallet body 1. After the adjustment is in place, the pull block is released, and under the elastic force of the second spring 11, the fixed insertion rod 10 is pushed to re-insert into the corresponding positioning hole 12, thereby achieving height fixation. The operation is simple, stable and reliable. When the ground is uneven, the level of the pallet body 1 can be quickly adjusted by adjusting the support adjustment mechanism installed inside one of the bases 2, ensuring that the goods are placed stably and improving the stability of the pallet body 1 in various environments.

[0017] refer to Figure 5 The clamping assembly includes a bidirectional lead screw 13 installed inside a symmetrical groove at the bottom of the pallet body 1. One end of the bidirectional lead screw 13 is connected to a bearing seat provided on the inner wall of the groove, and the other end of the bidirectional lead screw 13 extends out of the groove and is connected to a rotating handle. Symmetrical movable seats 14 are fitted on the bidirectional lead screw 13. An L-shaped connecting block 15 is installed at the bottom of the movable seat 14, and a clamping plate 16 is connected to the other end of the L-shaped connecting block 15. Anti-slip teeth are provided on one side of the clamping plate 16. More specifically, rotating the rotating handle drives the bidirectional lead screw 13 to rotate, thereby driving the two movable seats 14 to move towards or away from each other, causing the L-shaped connecting block 15 to move closer to or away from the clamping plate 16, so that the anti-slip teeth tightly abut against or loosen the fixed object. When the pallet body 1 is handled by a forklift, the clamping plate 16 can effectively limit the fork teeth on the forklift, preventing the pallet from sliding laterally or falling off during transportation and improving stability.

[0018] The implementation principle of a composite pallet according to an embodiment of this application is as follows: During use, when the height of the pallet body 1 is too low, pulling the pull block causes the movable rod 9 to press against the second spring 11, causing the fixed insert rod 10 to disengage from the positioning hole 12, thus releasing the restriction on the movable block 5. At this time, under the action of the first spring 6, the movable block 5 drives the support column 7 to move downwards, thereby adjusting the height of the pallet body 1. After adjustment, releasing the pull block allows the fixed insert rod 10 to be pushed back into the corresponding positioning hole 12 under the elastic force of the second spring 11, achieving height fixation. The operation is simple, stable, and reliable. When the surface is uneven, the level of the pallet body 1 can be quickly adjusted by adjusting the support adjustment mechanism installed inside one of the bases 2, ensuring that the goods are placed stably and improving the stability of the pallet body 1 in various environments. When the staff uses a forklift to move the pallet body 1, the staff first rotates the handle to drive the bidirectional lead screw 13 to rotate, which drives the two moving seats 14 to move towards each other, causing the L-shaped connecting block 15 to move closer to the clamping plate 16, so that the clamping plate 16 can effectively limit the fork teeth on the forklift, preventing the pallet from sliding laterally or falling off during transportation and improving stability.

[0019] 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.
