Description

Technical Field

[0001] This utility model relates to the field of pallet support technology, and specifically to a support structure. Background Technology

[0002] Pallets are a medium that transforms static goods into dynamic goods; they are a cargo-carrying platform, and moreover, a mobile platform, or a movable ground. Traditional pallets with leg structures typically have their base plate in direct contact with the ground. During use, the base plate is directly subjected to friction, wear, and even impact. Especially in high-wear or harsh working environments (such as industrial plants, construction sites, and logistics warehouses), the lower surface of the base plate is prone to wear, significantly reducing the service life of the pallet's leg structure.

[0003] Therefore, most existing outrigger structures have wear-resistant plates installed at the bottom of the base plate to reduce the risk of wear. However, the bottom of the existing base plate is not specifically designed for the installation of wear-resistant plates. When replacing wear-resistant plates, the installation position of the wear-resistant plates is not fixed, which greatly increases the difficulty and time consumption of manually adjusting and fixing the wear-resistant components. Utility Model Content

[0004] The purpose of this utility model is to provide a support leg structure that solves the problem that the lower end of the existing base plate does not have a specially designed structure for the installation of wear-resistant plates. When replacing wear-resistant plates, the installation position of the wear-resistant plates is not fixed, which greatly increases the construction difficulty and time consumption of manually adjusting and fixing wear-resistant parts.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A support leg structure is provided, including a first support column and a base plate. The upper end of the first support column is used to connect to a panel. The first support column is provided at both ends of the base plate. An installation groove is provided on the lower surface of the base plate. The installation groove extends from one end of the base plate to the other end of the base plate. The installation groove is used to reserve the installation position of a wear-resistant plate.

[0007] A further technical solution is as follows: the first support column includes a first plate and a second plate; there are two second plates, which are arranged opposite to each other on both sides of the first plate; wherein the first plate is connected to the end of the base plate, and the second plate is connected to the side wall of the base plate.

[0008] A further technical solution is: the side of the first plate closest to the second plate is bent away from the bottom plate to form a drainage hole between the side of the first plate closest to the second plate, the bottom plate, and the second plate.

[0009] A further technical solution is that the support leg structure also includes a support plate; the support plate is disposed above the base plate, and both ends of the support plate are respectively connected to the two first support columns.

[0010] A further technical solution is as follows: the support plate includes a third plate and a fourth plate; the third plate is disposed above the base plate, and both ends of the third plate are respectively connected to the two first support columns; there are two fourth plates, which are disposed opposite to each other on both sides of the upper surface of the third plate, and the two fourth plates are respectively connected to the inner sides of the two second plates.

[0011] A further technical solution is that the side of the fourth plate away from the bottom plate bends towards the third plate.

[0012] A further technical solution is that the support leg structure also includes a second support column; the second support column is disposed between the two first support columns, and the two ends of the second support column are respectively connected to the support plate and the base plate.

[0013] A further technical solution is that the support leg structure also includes a sealing plate; the sealing plate is disposed between the support plate and the base plate, and the end of the sealing plate is used to connect the first support column or the second support column.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] On the one hand, by setting up mounting slots and installing wear-resistant plates, components that directly contact the ground and bear wear are transferred from the base plate to the replaceable wear-resistant plates. The aim is to ensure that even if the wear-resistant plates become severely worn due to long-term use, only the wear-resistant plates need to be replaced, without replacing the entire base plate and support leg structure, thereby reducing replacement difficulty and maintenance costs. On the other hand, the mounting slots provide clear positioning and installation space for the wear-resistant plates, aiming to simplify the installation process, make it quick, and ensure accurate positioning.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Example 1: This example provides a support leg structure, such as... Figures 1-5 As shown, it includes a first support column 1 and a base plate 2. The upper end of the first support column 1 is used to connect the panel. The first support column 1 is provided at both ends of the base plate 2. The lower surface of the base plate 2 is provided with an installation groove 7, which extends from one end of the base plate 2 to the other end. The installation groove 7 is used to reserve the installation position of the wear-resistant plate 8.

[0029] For example, in implementation, the upper end of the first support column 1 is used to connect the panel of the tray, and there are two first support columns 1. The two first support columns 1 are arranged opposite each other at both ends of the base plate 2, and the lower ends of the first support columns 1 are connected to the base plate 2 by welding, screwing, or integral molding. An installation groove 7 is provided on the lower surface of the base plate 2. The installation groove 7 extends from one end of the base plate 2 to the other end of the base plate 2, and the installation groove 7 is used to reserve the installation position of the wear-resistant plate 8.

[0030] In practice, the wear-resistant plate 8 (usually made of non-metallic materials such as wood, nylon PA plastic, PE plastic, PP plastic, rubber, ceramic composite materials, etc.) is placed into the mounting groove 7 on the lower surface of the base plate 2. The wear-resistant plate 8 is then fixed in the mounting groove 7 using methods such as bolting, welding, or interference fits. The depth of the mounting groove 7 should be less than the thickness of the wear-resistant plate 8, so that after installation, the lower surface of the wear-resistant plate 8 protrudes beyond the lower surface of the base plate 2, ensuring direct contact with the ground or support surface for protection and wear resistance. On one hand, by setting up the mounting groove 7 and installing the wear-resistant plate 8, components that directly contact the ground and bear wear are transferred from the base plate 2 to the replaceable wear-resistant plate 8. The aim is to ensure that even if the wear-resistant plate 8 becomes severely worn due to long-term use, only the wear-resistant plate 8 needs to be replaced, without replacing the entire base plate 2 and the support leg structure, thereby reducing replacement difficulty and maintenance costs. On the other hand, the mounting slot 7 provides a clear positioning and installation space for the wear-resistant plate 8, with the aim of making the installation process simple, fast and accurate.

[0031] A preferred embodiment, such as Figure 5As shown, the base plate 2 includes a horizontal fixing plate 21 and a horizontal connecting plate 22. There are two horizontal connecting plates 22, which are symmetrically connected to both sides of the horizontal fixing plate 21 by welding, screwing, or integral molding. The horizontal connecting plate 22 includes a first vertical plate element 221, a first horizontal plate element 222, an arc-shaped plate element 223, a second horizontal plate element 224, a second vertical plate element 225, a third horizontal plate element 226, and a third vertical plate element 227. The first vertical plate element 221, the first horizontal plate element 222, the arc-shaped plate element 223, the second horizontal plate element 224, the second vertical plate element 225, the third horizontal plate element 226, and the third vertical plate element 227 are arranged sequentially from one side of the horizontal fixed plate body to the other side of the horizontal plate fixed plate body. The upper end of the first vertical plate element 221 is connected to one side of the first horizontal plate element 222, the other side of the first horizontal plate element 222 is connected to one side of the arc-shaped plate element 223, the other side of the arc-shaped plate element 223 is connected to one side of the second horizontal plate element 224, the other side of the second horizontal plate element 224 is connected to the lower end of the second vertical plate element 225, the upper end of the second vertical plate element 225 is connected to one side of the third horizontal plate element 226, the other side of the third horizontal plate element 226 is connected to the upper end of the third vertical plate element 227, and the lower end of the third vertical plate element 227 is connected to one side of the horizontal fixed plate body 21. The arc-shaped plate element 223 has its opening facing downwards, and the transverse fixing plate body 21 has pre-drilled connection holes 23 for connecting the wear-resistant plate. A mounting groove 7 is formed between the lower end faces of the first vertical plate element 221, the first horizontal plate element 222, the arc-shaped plate element 223, the second horizontal plate element 224, the second vertical plate element 225, the third horizontal plate element 226, the third vertical plate element 227, and the transverse fixing plate body 21. This makes the mounting groove 7 a non-standard groove structure, which aims to effectively enhance the overall support between the wear-resistant plate and the base compared to a standard mounting groove 7, and to reduce the risk of the pallet damaging the bolts securing the wear-resistant plate during forklift entry.

[0032] Example 2: Based on Example 1 above, in this example, as follows... Figure 2 As shown, the first support column 1 includes a first plate 11 and a second plate 12; there are two second plates 12, which are arranged opposite to each other on both sides of the first plate 11; wherein, the first plate 11 is connected to the end of the base plate 2, and the second plate 12 is connected to the side wall of the base plate 2.

[0033] For example, in the implementation process, the first support column 1 includes a first plate 11 and a second plate 12. There are two second plates 12, which are symmetrically arranged on both sides of the first plate 11, and the second plates 12 are connected to the first plate 11 by means of welding, screwing, integral molding, etc.

[0034] In the specific implementation process, the base plate 2 is installed between the two second plates 12, and the ends of the base plate 2 are connected to the first plate 11 by welding, screwing, or integral molding. The two sides of the base plate 2 are respectively connected to the two second plates 12 by welding, screwing, or integral molding. This achieves multi-faceted connections between the sidewalls of the base plate 2 and the second plates 12, as well as between the ends of the base plate 2 and the first plate 11, in order to improve the connection strength between the first support column 1 and the base plate 2, thereby significantly improving the tensile, shear, and bending resistance of the leg structure, and thus enhancing the rigidity and load-bearing stability of the leg structure.

[0035] During implementation, the surface of the outrigger structure undergoes an electrophoretic spraying composite process (pickling, phosphating pretreatment + electrophoresis + powder coating) to improve its weather resistance, corrosion resistance, and resistance to discoloration and chalking, thereby extending its service life. Therefore, to facilitate the removal of liquids and impurities retained on the base plate 2 during the electrophoretic spraying composite process, Example 3: Based on Example 2 above, as... Figure 2 As shown, in this embodiment, the side of the first plate 11 near the second plate 12 is bent away from the bottom plate 2 to form a drainage hole 3 between the side of the first plate 11 near the second plate 12, the bottom plate 2, and the second plate 12.

[0036] For example, during implementation, the side of the first plate 11 closest to the second plate 12 is bent away from the base plate 2 to form a drainage hole 3 between the surface of the first plate 11, the end face of the base plate 2, and the surface of the second plate 12. The shape of the drainage hole 3 can be rectangular, circular, arc-shaped, or other geometric shapes that facilitate liquid flow. There are two drainage holes 3, located on opposite sides of the first plate 11. During the electrophoretic spraying composite process, liquid and impurities on the upper surface of the base plate 2 can flow out through the drainage holes 3 at the end of the base plate 2, from the upper surface to the lower surface of the base plate 2. This aims to reduce the risk of uneven coating, bubbles, or pinholes caused by liquid retention, thereby improving the surface quality and aesthetics of the leg structure.

[0037] In one alternative implementation, a QR code is provided on the side of the first plate 11 away from the base plate 2. The two sides of the first plate 11 are bent away from the base plate 2, so that the QR code is located within a groove on the side of the first plate 11 away from the base plate 2. This aims to reduce the risk of QR code damage.

[0038] Example 4: Based on Example 3 above, in this example, as... Figure 1 As shown, the support leg structure also includes a support plate 4; the support plate 4 is disposed above the base plate 2, and both ends of the support plate 4 are respectively connected to the two first support columns 1.

[0039] For example, in implementation, the aforementioned support leg structure also includes a support plate 4. The support plate 4 is arranged in parallel directly above the base plate 2, and both ends of the support plate 4 are connected to the two first support columns 1 by welding, screwing, or integral molding, respectively. This forms a double-layer load-bearing structure between the support plate 4 and the base plate 2, aiming to significantly improve the flexural resistance of the support leg structure under vertical loads, thereby reducing the risk of deformation of the base plate 2 or the panel due to concentrated loads.

[0040] In one optional embodiment, the aforementioned drainage hole 3 extends along the support plate 4 toward the base plate 2 and penetrates both the support plate 4 and the base plate 2. This is intended to facilitate the flow of liquids and impurities from the upper surface of the support plate 4 through the drainage hole 3 at the end of the support plate 4, flowing from the upper surface of the support plate 4 toward the lower surface of the support plate 4. This reduces the risk of defects such as uneven coating, bubbles, or pinholes caused by liquid retention, thereby improving the surface quality and aesthetics of the leg structure.

[0041] Example 5: Based on Example 4 above, in this example, as... Figure 2 As shown in Figure 4, the support plate 4 includes a third plate 41 and a fourth plate 42; the third plate 41 is disposed above the base plate 2, and both ends of the third plate 41 are respectively connected to the two first support columns 1; there are two fourth plates 42, which are disposed opposite to each other on both sides of the upper surface of the third plate 41, and the two fourth plates 42 are respectively connected to the inner sides of the two second plates 12.

[0042] For example, in the implementation process, the support plate 4 includes a third plate 41 and a fourth plate 42. The third plate 41 is arranged in parallel above the base plate 2, and the two ends of the third plate 41 are respectively connected to the two first support columns 1 by welding, screwing, or integral molding.

[0043] Two fourth plates 42 are provided, and the two fourth plates 42 are connected to the two sides of the upper surface of the third plate 41 by means of welding, screwing, or integral molding. The two fourth plates 42 are also connected to the inner sides of the two second plates 12 by means of welding, screwing, or integral molding. The third plate 41 and the fourth plates 42 jointly bear the pressure from the panel, aiming to further improve the rigidity and deformation resistance of the leg structure, thereby enhancing the leg structure's resistance to flexural bending under vertical loads.

[0044] In a preferred embodiment, the third plate 41 and the fourth plate 42 form an upward-facing groove structure. The drainage hole 3 can better drain liquids and impurities between the third plate 41 and the fourth plate 42. This aims to reduce the risk of defects such as uneven coating, bubbles, or pinholes caused by liquid retention, thereby improving the surface quality and aesthetics of the leg structure.

[0045] Example 6: Based on Example 5 above, in this example, as... Figure 4 As shown, the fourth plate 42 bends towards the third plate 41 from the side away from the bottom plate 2.

[0046] For example, during implementation, the side of the fourth plate 42 furthest from the base plate 2 (i.e., the upper edge) bends towards the third plate 41. That is, in the upper edge region of the fourth plate 42, the material is bent or rolled towards the third plate 41, forming an inwardly inclined or horizontally extending curved edge. In other words, the upper ends of the two fourth plates 42 converge inward, forming a box-like or trapezoidal cross-section structure with a narrowed top. After the upper ends of the fourth plates 42 bend inward, the originally open "U-shaped groove" structure tends to close, forming a box-like cross-section, aiming to significantly increase the section moment of inertia and torsional constant, thereby effectively suppressing the risk of torsion and lateral deformation of the support plate 4 under load.

[0047] In longer pallets, the middle sections of the panel, support plate 4, and base plate 2 are prone to downward deflection due to concentrated loads. Therefore, to reduce the risk of downward bending deformation of the middle sections of the panel, support plate 4, and base plate 2 under load, Example 7: Based on Example 4 above, in this example, as... Figure 1 As shown, the support leg structure also includes a second support column 5; the second support column 5 is disposed between the two first support columns 1, and the two ends of the second support column 5 are respectively connected to the support plate 4 and the base plate 2.

[0048] For example, in implementation, the aforementioned support leg structure also includes a second support column 5. The second support column 5 is positioned between the two first support columns 1, and its upper end is connected to the support plate 4 by welding, screwing, or integral molding. Its lower end is connected to the base plate 2 by welding, screwing, or integral molding, forming a vertical intermediate support. This aims to reduce the risk of downward bending deformation of the panel, support plate 4, and base plate 2 under load.

[0049] In a preferred embodiment, a plurality of second support columns 5 are provided, which are evenly distributed along one end of the base plate 2 toward the other end. This aims to achieve multi-point support using multiple second support columns 5, thereby further increasing the tray length and reducing the risk of downward bending deformation of the panel, support plate 4, and center of the base plate 2 due to load.

[0050] In a preferred embodiment, the center span between two adjacent second support columns 5 is the same as the center span between the two crossbeams of the shelf.

[0051] Example 8: Based on Example 7 above, in this example, as... Figure 1 As shown, the support leg structure also includes a sealing plate 6; the sealing plate 6 is disposed between the support plate 4 and the base plate 2, and the end of the sealing plate 6 is used to connect the first support column 1 or the second support column 5.

[0052] For example, in implementation, the aforementioned outrigger structure also includes a sealing plate 6. The sealing plate 6 is disposed in the lateral space between the support plate 4 and the base plate 2, and its upper and lower sides are connected to the support plate 4 and the base plate 2 respectively by welding, screwing, or snap-fitting. One end of the sealing plate 6 is connected to the first support leg (second support leg) by welding, screwing, or snap-fitting, and the other end is connected to the first support leg (second support leg) by welding, screwing, or snap-fitting, forming a laterally enclosed structure. On one hand, the sealing plate 6 encloses the side of the outrigger, forming a box-like structure, aiming to significantly improve the torsional constant and lateral stiffness of the cross-section, thereby effectively suppressing torsional, opening, or shear deformation during forklift insertion, thus enhancing structural stability. On the other hand, the sealing plate 6 can prevent dust, debris, liquids, and other foreign matter from entering the outrigger, preventing internal contamination and corrosion risks, thereby improving adaptability to the operating environment.
