Description

Technical Field

[0001] The invention relates to the technical field of logistics and transportation, in particular to a pallet made of a novel composite material. Background Art

[0002] A pallet is a horizontal platform device used for packaging, stacking, handling and transporting goods and products as unit loads. As a kind of container equipment similar to containers, pallets are now widely used in production, transportation, warehousing and circulation. Referring to the Chinese patent, the announcement number is "CN118124945B" "An Improved Logistics Pallet", which points out that the existing pallets lack a limiting device, and it is easy for goods to fall off the pallet during transportation, affecting the transportation of goods. In addition, most logistics pallets cannot be spliced, which makes it inconvenient to transport multiple pallets at one time, affecting the efficiency of transportation. However, the equipment still has the problems of poor convenience of use and high investment. In this regard, we propose a new type of composite material pallet to solve the above problems. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a pallet made of a novel composite material, which solves the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A new type of composite material pallet, including a base body and a load-bearing platform, a connection slot is opened on one side of the base body, a connection plug is fixedly installed on the side of the base body away from the connection slot, the connection plug is adapted to the connection slot, and is used to plug multiple base bodies together;

[0005] Limiting slides are fixedly installed on both sides of the load-bearing platform, and a concave plug-in slot matching the load-bearing platform is provided on the top surface of the base body. The load-bearing platform and the base body are plugged together through the matching of the limiting slides and the concave plug-in slots;

[0006] Positioning slide bars are slidably installed inside the multiple base bodies, and positioning disc frames are fixedly installed at the ends of the multiple positioning slide bars, a spring body is sleeved on the outer side of the positioning slide bars, and a plurality of positioning protrusions are fixedly installed on the top surface of the positioning disc frame. The installation position of the positioning disc frame is located below the corresponding load-bearing platform, and is used to lock the load-bearing platform and the base body when goods are loaded on the load-bearing platform.

[0007] Preferably, a counterweight ring is fixedly mounted on one end of the positioning slide bar away from the positioning disc frame, and the counterweight ring is coaxial with the positioning slide bar.

[0008] Preferably, a load-bearing pad is fixedly installed inside the concave plug-in slot, the load-bearing pad is located below the load-bearing platform and fits with it, and the load-bearing pad is used to support the load-bearing platform.

[0009] Preferably, an annular through hole is provided at the inner center of the load-bearing pad for the positioning disc rack and the positioning slide rod to pass through.

[0010] Preferably, the opening position of the annular through hole is coaxial with the positioning disc frame.

[0011] Preferably, a plurality of reinforcing cross bars are fixedly installed inside the load-bearing platform, and the plurality of reinforcing cross bars are parallel to each other.

[0012] Preferably, a plurality of through holes are symmetrically opened inside the plurality of load-bearing plates, limiting protrusions are slidably installed inside the plurality of through holes, and return springs are sleeved on the outer sides of the plurality of limiting protrusions.

[0013] Preferably, the installation heights of the plurality of limiting convex rods are the same, and they are used to limit the placed goods. The ends of the plurality of limiting convex rods are all provided with arc-shaped surfaces, and the plurality of limiting convex rods are always kept parallel.

[0014] Preferably, concave grooves are symmetrically provided on both sides of the bottom of the base body, and buffer bottom plates are slidably installed inside the concave grooves on both sides, and multiple buffer springs are fixedly installed between the ends of the buffer bottom plates and the insides of the corresponding concave grooves, which are used to buffer the force generated during the placement of the base body.

[0015] Preferably, the buffer bottom plates at the bottom of the same base body always remain parallel.

[0016] The present invention provides a new type of composite material pallet. Compared with the prior art, it has the following beneficial effects:

[0017] (1) The new composite material pallet, through the coordination between the load-bearing platen and the base body, can facilitate the assembly of the pallet during use. Compared with the traditional pallet, it can ensure light weight and high load. The continuous fiber composite material has higher specific strength and specific stiffness, which enables it to achieve better load operation and ensure the elastic size of the equipment. Pallets of different sizes can be made by simply adjusting the cutting length of the load-bearing platen, which greatly reduces fixed investment while ensuring production efficiency.

[0018] (2) The new composite material pallet, through the setting of the base body, can facilitate the assembly of the pallet and the separate replacement of the base body and the load-bearing platform, thus saving costs. At the same time, when in use, the coordination of components such as positioning slide rods and positioning tray racks can ensure that the assembled pallet has good stability, thereby ensuring the loading and transportation effects of goods.

[0019] (3) The pallet of the new composite material has multiple limit protrusions installed inside the load-bearing platform. As the goods are placed on top of the load-bearing platform, the limit protrusions at the bottom of the goods can be compressed into the inside of the load-bearing platform, while the limit protrusions on the outside of the goods can remain in the lifted state. By having multiple lifted limit protrusions located on the outside of the goods, the goods can be prevented from shifting during the transportation process, further improving the use effect of the equipment and the safety of the operation.
