Description

Technical Field

[0001] This application relates to the field of logistics packaging technology, and in particular to a reinforcing structure for a molded pallet. Background Technology

[0002] Molded pallets, widely used in modern logistics, are favored for their lightweight, environmental friendliness, and recyclability. However, traditional molded pallets often suffer from insufficient strength, easy deformation, and short service life when bearing heavy loads or subjected to impacts. Current technologies typically increase the wall thickness or employ simple reinforcing ribs to improve the strength of molded pallets. However, simply increasing the wall thickness increases material costs and pallet weight, hindering transportation and handling; while simple reinforcing ribs often fail to provide comprehensive and effective support, especially in localized stress areas where stress concentration and structural failure can still occur. For example, the edges, center, and foot connections of the pallet are areas of high stress; insufficient reinforcement in these areas can lead to collapse and cracking during actual use, severely impacting its load-bearing capacity and service life.

[0003] Therefore, we propose a reinforced structure for a molded tray. Utility Model Content

[0004] The main purpose of this application is to solve the problems of insufficient strength, easy deformation, and short service life of molded pallets in the prior art, and to provide a reinforced structure for molded pallets that has a reasonable structure, strong load-bearing capacity, high stability, and long service life.

[0005] To achieve the above objectives, this application provides a reinforcing structure for a molded pallet, including a plurality of edge supports disposed around the periphery of the pallet body, a plurality of support supports disposed in the middle of the pallet body, and a plurality of positioning supports spaced apart between the edge supports; the support supports are arranged along the long axis of the pallet body, and the positioning supports are located on the same axis as the edge supports and are arranged side by side with the support supports on the bottom surface of the pallet body;

[0006] The edge support feet are connected by horizontal reinforcing ribs. The support feet include edge support feet located on both sides of the tray body and a central support foot located between the two edge support feet. The outer periphery of the central support foot is provided with a reinforcing ring. The reinforcing ring has a polygonal structure and is stably connected to the edge support feet and positioning support feet through the outer horizontal reinforcing ribs.

[0007] Preferably, the reinforcing ring is an equilateral octagonal structure with equal side lengths and uniform included angles between adjacent sides; its four horizontal sides are welded to or integrally formed with horizontal reinforcing ribs; and the oblique sides are arranged perpendicularly to the oblique reinforcing ribs.

[0008] Preferably, the horizontal reinforcing ribs include vertical reinforcing ribs and transverse reinforcing ribs; the transverse reinforcing ribs extend along the long axis of the pallet body and are arranged collinearly with the positioning feet and edge feet; the vertical reinforcing ribs extend along the width of the pallet body and are arranged perpendicularly to the transverse reinforcing ribs at 90°, together forming a mutually abutting rectangular grid support structure.

[0009] Preferably, the outer periphery of the edge support foot is further provided with an edge reinforcing rib, which obliquely penetrates the edge support foot and together with the horizontal flange of the tray body edge forms a triangular stable structure.

[0010] Preferably, the triangular stabilizing structures are evenly spaced along the periphery of the pallet body, and the inclination directions of adjacent sets of triangular stabilizing structures are opposite.

[0011] Preferably, it further includes: an arc-shaped reinforcing rib, the concave surface of which smoothly transitions to the side surface of the transverse reinforcing rib and / or the vertical reinforcing rib, forming an approximately streamlined support cavity, and its convex surface facing the grid space enclosed by the rectangular grid support structure.

[0012] Preferably, the arc-shaped reinforcing ribs located on both sides of the same horizontal reinforcing rib and / or vertical reinforcing rib are symmetrically arranged, and their height is parallel to the height of the horizontal reinforcing rib and / or vertical reinforcing rib.

[0013] Preferably, the edge support, the supporting support, and the positioning support all adopt a multi-layer stepped structure.

[0014] The beneficial effects of this utility model's technical solution are as follows:

[0015] By incorporating horizontal reinforcing ribs between the edge supports and designing them as a rectangular grid support structure with perpendicularly intersecting horizontal and vertical reinforcing ribs, the overall rigidity and deformation resistance of the pallet bottom are significantly enhanced. This grid structure can evenly distribute local loads across the entire pallet bottom, effectively avoiding stress concentration and thus significantly improving the pallet's load-bearing capacity and impact resistance.

[0016] The horizontal reinforcing ribs are aligned with the positioning support feet and edge support feet, forming an integrated support system that further enhances the support strength of the pallet edges and center, effectively preventing the pallet edges from collapsing and deforming.

[0017] The rectangular grid support structure design provides excellent support for the pallet in all directions, offering stable support regardless of how the goods are placed, thus extending the pallet's lifespan.

[0018] The addition of reinforcing rings, edge reinforcing ribs, arc-shaped reinforcing ribs, and honeycomb structure bases further enhances the local strength, overall stability, and fatigue resistance of the pallet, enabling it to exhibit excellent performance under various complex working conditions.

[0019] In addition, this solution mainly improves strength through structural optimization rather than simply increasing material thickness, which can effectively control material costs and pallet weight while ensuring load-bearing capacity. Attached Figure Description

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one feature.

[0024] like Figures 1-2 As shown, this utility model provides a reinforcing structure for a molded pallet, including a plurality of edge supports 200 disposed around the periphery of the pallet body 100, a plurality of support supports 300 disposed in the middle of the pallet body 100, and a plurality of positioning supports 400 spaced apart from the edge supports 200. The support supports 300 are arranged along the long axis of the pallet body 100, and the positioning supports 400 are located on the same axis as the edge supports 200 and are arranged side by side with the support supports 300 on the lower surface of the pallet body 100.

[0025] Furthermore, horizontal reinforcing ribs 500 are connected between the edge support feet 200. The horizontal reinforcing ribs 500 include transverse reinforcing ribs 501 and vertical reinforcing ribs 502. The transverse reinforcing ribs 501 extend along the long axis of the tray body 100 and are collinear with the positioning support feet 400 and the edge support feet 200.

[0026] Specifically, the transverse reinforcing ribs 501 directly connect to and support all the feet at the bottom of the pallet, forming a continuous support beam that runs through the long axis of the pallet. The vertical reinforcing ribs 502 extend along the width of the pallet body 100 and are arranged perpendicularly to the transverse reinforcing ribs 501 at 90°, together forming a mutually abutting rectangular grid support structure.

[0027] In this embodiment, the rectangular grid support structure creates a high-strength, high-rigidity overall frame at the bottom of the pallet. When the pallet carries heavy loads, the load is transferred through the pallet body 100 to the lower support feet 200, 300, 400, and horizontal reinforcing ribs 500. Because the horizontal reinforcing ribs 501 and vertical reinforcing ribs 502 intersect and abut each other perpendicularly, they effectively distribute localized stress throughout the grid structure, avoiding stress concentration in a single direction. For example, when the center of the pallet is subjected to heavy pressure, the horizontal reinforcing ribs 501 and vertical reinforcing ribs 502 work together to evenly distribute the pressure to all support feet, significantly improving the overall load-bearing capacity and deformation resistance of the pallet. Furthermore, the collinear arrangement of the horizontal reinforcing ribs 501 with the positioning support feet 400 and the edge support feet 200 makes the support at the edges and center of the pallet more stable, effectively preventing collapse and deformation of the pallet edges, thereby increasing the strength of the pallet and extending its service life.

[0028] In one embodiment, the tray body 100, edge support feet 200, support feet 300, positioning feet 400, and horizontal reinforcing ribs 500 are integrally formed. This integral forming process eliminates weak points at the joints, further improving the overall integrity and strength of the structure, while simplifying the manufacturing process and reducing production costs.

[0029] In one embodiment, the support foot 300 includes edge support feet 301 located on both sides of the tray body 100 and a central support foot 302 located between the two edge support feet 301.

[0030] Furthermore, a reinforcing ring 503 is provided around the outer periphery of the central support foot 302. The reinforcing ring 503 can provide additional radial support for the central support foot 302, effectively preventing it from deforming or buckling under heavy pressure.

[0031] Among them, the reinforcing ring 503 has a polygonal structure, which is connected to the horizontal reinforcing rib 500 and the transverse reinforcing rib 501 to form a closed ring support frame.

[0032] In this embodiment, the connection between the polygonal structure and the horizontal reinforcing ribs ensures that the reinforcing ring 503 is not merely a localized reinforcement of the central support foot, but is integrated into the entire grid system of the horizontal reinforcing ribs, forming a more stable overall support frame. The closed ring structure provides all-around support, further enhancing the load-bearing capacity of the central area.

[0033] In one embodiment, the reinforcing ring 503 is preferably an equilateral octagonal structure with equal side lengths and uniform included angles between adjacent sides. This octagonal structure provides good support while also exhibiting good stress dispersion. The four horizontal sides of the reinforcing ring 503 are connected to the horizontal reinforcing ribs 500 and the transverse reinforcing ribs 501, respectively, ensuring a tight connection with the main reinforcing ribs. Its four oblique sides are connected to the positioning support feet 400 and the edge support feet 200 via oblique reinforcing ribs 504. The oblique reinforcing ribs 504 are arranged perpendicularly to the oblique sides. By connecting the reinforcing ring 503 with the surrounding positioning support feet 400 and edge support feet 200 through the oblique reinforcing ribs 504, a more complex, multi-directional support network is formed, allowing the force on the central support foot 302 to be more effectively transferred to the entire bottom of the pallet, greatly enhancing the compressive and torsional resistance of the pallet's center.

[0034] In one embodiment, the outer periphery of the edge support 200 is further provided with an edge reinforcing rib 505. The edge reinforcing rib 505 obliquely penetrates the edge support 200 and together with the horizontal flange of the edge of the tray body 100, forms a triangular stable structure.

[0035] In this embodiment, by introducing this triangular stabilizing structure at the edge support, the pallet edge's resistance to lateral impact and bending can be significantly enhanced, effectively preventing damage to the pallet edge during handling or stacking.

[0036] Furthermore, the triangular stabilizing structures are evenly spaced along the perimeter of the pallet body 100, and the inclination directions of adjacent sets of triangular stabilizing structures are opposite. This symmetrical and staggered arrangement ensures that the pallet edge has balanced impact resistance in all directions, further enhancing the overall stability of the pallet.

[0037] In one embodiment, an arc-shaped reinforcing rib 506 is also included. The concave surface of the arc-shaped reinforcing rib 506 smoothly transitions to the side surface of the transverse reinforcing rib 501 and / or the vertical reinforcing rib 502, forming an approximately streamlined support cavity, and its convex surface faces the grid space enclosed by the rectangular grid support structure.

[0038] In this embodiment, the reinforcing ribs utilize the advantages of curved structures in terms of compressive and bending resistance, which can further improve the local stiffness of the reinforcing ribs while reducing stress concentration. The streamlined support cavity is not only aesthetically pleasing but also reduces its weight to some extent and may facilitate demolding during compression molding.

[0039] Furthermore, symmetrically arranged arc-shaped reinforcing ribs 506 are positioned on both sides of the same horizontal reinforcing rib 501 and / or vertical reinforcing rib 502, with their height parallel to the height of the horizontal reinforcing rib 501 and / or vertical reinforcing rib 502. The symmetrically arranged arc-shaped reinforcing ribs provide balanced support, ensuring that the reinforcing ribs do not deflect under stress, further enhancing the overall stability of the grid structure.

[0040] In one embodiment, the edge support 200, the support support 300, and the positioning support 400 all adopt a honeycomb structure base. The honeycomb structure is characterized by high strength and lightweight. By using a honeycomb structure inside the support, the compressive strength and impact toughness of the support can be significantly improved without significantly increasing material consumption, further enhancing the overall load-bearing capacity and service life of the pallet.
