Description

[0001] This invention is a divisional application with the application date of "2021.7.7", application number "202110769522.8", and application title "Support Unit and Platform". Technical Field

[0002] This invention relates to the field of platform technology, and particularly to a support unit and platform. Background Technology

[0003] Pallets, also known as forklift pallets, are used to support materials or products and are widely used as support structures in logistics and transportation. In related technologies, pallets are generally made of plastic or wood. However, plastic pallets are easily damaged by forklift collisions and have limited load-bearing capacity; wooden pallets are prone to absorbing moisture and mold, and require fumigation before use, resulting in high operating costs. Furthermore, wooden pallets lack sufficient strength and are easily damaged. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a support unit with high structural strength, strong load-bearing capacity, and light weight.

[0005] The present invention also proposes a platform having the above-mentioned support unit.

[0006] According to a first aspect of the present invention, a support unit includes: a first plate; a second plate, the second plate and the first plate being spaced apart in a vertical direction; wherein the first plate is deformed in the direction toward the second plate to form a plurality of spaced first annular walls; the second plate is deformed in the direction toward the first plate to form a plurality of spaced second annular walls, the plurality of second annular walls being correspondingly disposed with the plurality of first annular walls, the second annular walls being sleeved on the outside of the first annular walls, the first annular walls and the second annular walls being fitted together to form a support structure for supporting the first plate and the second plate, and forming a through hole in a vertical direction.

[0007] The support unit according to embodiments of the present invention has at least the following beneficial effects:

[0008] The first and second plates are spaced apart in the vertical direction. Multiple first annular walls, formed by the deformation of the first plate towards the second plate, are correspondingly fitted onto the outer sides of multiple second annular walls, formed by the deformation of the second plate towards the first plate. This close fit between the first and second annular walls ensures a tight connection between the first and second plates, improving the stability of the connection. Furthermore, the close fit between the first and second annular walls forms a support structure for supporting the first and second plates. This support structure, spaced apart between the first and second plates, can combine with the first and second plates to form a stable support unit, giving the support unit advantages of high structural strength and strong load-bearing capacity. The spaced arrangement of the first and second plates, and the interconnecting holes formed by the first annular walls in the vertical direction, create cavities between the first and second plates and within the support structure, effectively reducing the weight of the support unit while ensuring its structural strength.

[0009] According to some embodiments of the present invention, the inner diameter of the cross-section of at least a portion of the first annular wall gradually increases along a direction away from the first plate.

[0010] According to some embodiments of the present invention, the first ring wall and the second ring wall are fitted together by extruding and deforming towards the outside of the first ring wall.

[0011] According to some embodiments of the present invention, at least a portion of the first annular wall has a taper in the vertical direction.

[0012] According to some embodiments of the present invention, at least a portion of the longitudinal section of the first ring wall is inclined relative to the axis of the first ring wall and the inclination angle ranges from 1 degree to 3 degrees.

[0013] According to some embodiments of the present invention, the first annular wall extends outward from the end away from the first plate and has a first edge, which is in contact with the second plate.

[0014] According to some embodiments of the present invention, the first ring wall extends outward from the end away from the first plate and is provided with a first edge, and a second guide edge is provided at the connection between the second plate and the second ring wall, the second guide edge being in contact with the first edge.

[0015] According to some embodiments of the present invention, the first edge and the second guide edge, as well as the first annular wall and the second annular wall, together form the support structure.

[0016] According to some embodiments of the present invention, a first guide edge is provided at the connection between the first plate and the first annular wall, and a second edge is provided at the end of the second annular wall away from the second plate in a direction away from the first annular wall, and the second edge is in contact with the first guide edge.

[0017] According to a second aspect of the present invention, the platform includes the support unit described in the above embodiments.

[0018] The platform board according to embodiments of the present invention has at least the following beneficial effects:

[0019] The support unit of the first aspect embodiment comprises a first plate and a second plate spaced apart in the vertical direction. Multiple first annular walls formed by the deformation of the first plate toward the second plate are correspondingly fitted onto the outer sides of multiple second annular walls formed by the deformation of the second plate toward the first plate. The fit between the first and second annular walls secures the first and second plates, improving the stability of the connection. Furthermore, the fit between the first and second annular walls forms a support structure for supporting the first and second plates. This support structure, spaced apart between the first and second plates, can combine with the first and second plates to form a stable support unit, giving the platform plate advantages of high structural strength and strong load-bearing capacity. The spaced arrangement of the first and second plates, and the interconnecting holes formed by the first annular walls in the vertical direction, create cavities between the first and second plates and within the support structure, effectively reducing the weight of the platform plate while ensuring its structural strength.

[0020] According to some embodiments of the present invention, the support unit is formed as a tray. The first plate has a third through hole and a third annular wall. The third annular wall is located on the outer periphery of the third through hole and extends toward and abuts against the second plate. The second plate has a fourth through hole and a fourth annular wall. The fourth annular wall is located on the outer periphery of the fourth through hole and extends away from the first plate. The bottom of the tray has a support foot. The support foot is a cone structure with an open upper end and a hollow center. The support foot is fitted onto the fourth annular wall. The outer diameter of the support foot gradually decreases along the direction away from the tray. The diameter of the third through hole is larger than the diameter of the fourth through hole. The support foot includes a bottom wall and a peripheral wall. One end of the peripheral wall is connected to the bottom wall, and the other end is connected to the outer side of the fourth annular wall. The bottom wall has a fifth through hole. The end of the peripheral wall away from the bottom wall has a mounting edge, which abuts against the second plate.

[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0043] In the description of this invention, "multiple" refers to two or more. The use of terms like "first," "second," "third," "fourth," and "fifth" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, the number of technical features indicated, or the order in which the technical features are indicated.

[0044] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0045] Reference Figure 1 As shown, a platform 1000 according to an embodiment of the present invention includes a pallet 200 for carrying goods, the pallet 200 being formed by assembling a plurality of support units 100. In this embodiment, the platform 1000 achieves load-bearing capacity through the support units 100, exhibiting strong load-bearing capacity and allowing for use in multiple stages of logistics transportation.

[0046] Reference Figure 2 and Figure 3 As shown, a support unit 100 according to one embodiment of the present invention can be used on panel structures such as platform boards and box bodies to bear loads. The support unit 100 of this embodiment includes a first plate 110 and a second plate 120 spaced apart along the vertical direction. The first plate 110 and the second plate 120 can be made of metal materials, such as sheet metal parts. Using sheet metal parts for the first plate 110 and the second plate 120 simplifies the manufacturing process of the support unit 100, and the resulting support unit 100 has high structural strength and light weight. It is understood that the first plate 110 and the second plate 120 can also be made of other thin metal sheet materials. Using metal for the first plate 110 and the second plate 120 facilitates recycling and reuse, is environmentally friendly, and saves resources.

[0047] It is understandable that both the first plate 110 and the second plate 120 are made of galvanized sheet or electrolytic sheet. Galvanized sheet and electrolytic sheet have many advantages, such as high strength, high ductility, corrosion resistance, nuclear radiation resistance, high efficiency in reflecting ultraviolet rays, easy processing, light weight, recyclability, pest resistance, and low carbon and environmental protection.

[0048] Reference Figure 1 As shown, for example, when the support unit 100 is used to manufacture the platform, the support unit 100 is made of galvanized sheet or electrolytic sheet to make the platform, which fully meets the usage requirements of the platform. Moreover, the platform made of galvanized sheet or electrolytic sheet generates very little waste after disassembly, and the recycling rate of the disassembled galvanized sheet or electrolytic sheet is more than 80%, which meets the environmental performance requirements.

[0049] Continue to refer to Figure 2 and Figure 3 As shown, it can be understood that the lower end face of the first plate 110 is provided with a plurality of first annular walls 111 spaced apart along the length and width directions of the first plate 110. The plurality of first annular walls 111 extend toward the second plate 120, and the first annular walls 111 are hollow cylindrical structures that are open from top to bottom. The upper end face of the second plate 120 is provided with a plurality of second annular walls 121 spaced apart along the length and width directions of the second plate 120. The plurality of second annular walls 121 extend toward the first plate 110, and the second annular walls 121 are hollow cylindrical structures that are open from top to bottom. It should be noted that the lower end face and the upper end face referred to here are only for this specific embodiment and are not limited to their absolute positions, but should be understood as their relative positions. For example, the lower end face of the first plate 110 is the end face of the first plate 110 facing the second plate 120, and the upper end face of the second plate 120 is the end face of the second plate 120 facing the first plate 110.

[0050] Multiple second annular walls 121 are correspondingly arranged with multiple first annular walls 111. The second annular walls 121 are fitted onto the outer side of the first annular walls 111. The second annular walls 121 and the first annular walls 111 can be configured for a tight fit connection, thereby allowing the first annular walls 111 and the second annular walls 121 to fit together to form a stable support structure 130. The support structure 130 is used to support the first plate 110 and the second plate 120. It should be noted that a tight fit connection can be understood as a connection method in which there is no relative movement between the first annular walls 111 and the second annular walls 121. The first annular walls 111 and the second annular walls 121 can be an interference fit or a transition fit connection, or a fully fitted or partially fitted connection. The first annular walls 111 and the second annular walls 121 can achieve a tight fit connection through extrusion deformation, which is not specifically limited here.

[0051] Multiple support structures 130 are hollow cylindrical structures. These support structures 130 are spaced apart between the first plate 110 and the second plate 120, forming a support for both plates. They combine with the first and second plates 110 to form a stable support unit 100. Furthermore, the support structures 130, formed by the cooperation of the first annular wall 111 and the second annular wall 121, have high rigidity and are not easily deformed by compression, effectively preventing bending or torsion of the first and second plates 110 and 120, thereby improving the structural strength of the support unit 100. The support unit 100 bears the load on the first plate 110 or the second plate 120 through the support structures 130, distributing the load across the multiple support structures 130, thus enhancing the load-bearing capacity of the support unit 100.

[0052] Moreover, the tight fit between the first ring wall 111 and the second ring wall 121 makes the connection between the first plate 110 and the second plate 120 more secure, thereby improving the connection stability between the first plate 110 and the second plate 120.

[0053] In addition, the support structure 130 is a hollow structure, with cavities formed between the first plate 110 and the second plate 120 and inside the support structure 130. This can effectively reduce the weight of the support unit 100 while ensuring the structural strength of the support unit 100, making the support unit 100 lighter and easier to transport.

[0054] It is understood that the first annular wall 111 can be formed by stamping the first plate 110, that is, the first annular wall 111 and the first plate 110 are integrally formed structures; the first annular wall 111 can also be fixedly connected to the first plate 110 by welding, riveting, etc., which are not specifically limited here. When the first annular wall 111 is formed by stamping the first plate 110, the first plate 110 can be punched first and then stamped to form the first annular wall 111, or the first plate 110 can be stamped first and then punched to form the first annular wall 111.

[0055] Reference Figure 3As shown, in some embodiments of the present invention, the upper end of the second annular wall 121 (i.e., the end away from the second plate 120) extends outward with a second edge 122. The second edge 122 can be formed by bending the second annular wall 121 or integrally formed by the second plate 120. The second edge 122 fits against the first plate 110, thereby making the first annular wall 111 and the second annular wall 121 fit more closely and the connection more secure, thus improving the structural strength of the support structure 130. Moreover, the second edge 122 can support the first plate 110 and the connection between the first plate 110 and the first annular wall 111, so that the second annular wall 121 can more stably bear the load of the first plate 110, thereby improving the load-bearing capacity of the support unit 100. In addition, the second edge 122 can be formed as an arc-shaped chamfer, so that when the first plate 110 and the second plate 120 are joined, the second edge 122 has a guiding function, which can guide the first ring wall 111 to be fitted into the second ring wall 121, thereby making the joining of the first plate 110 and the second plate 120 smoother and improving assembly efficiency.

[0056] Reference Figure 3 As shown, in some embodiments of the present invention, a first guide edge 113 is provided at the connection between the first plate 110 and the first annular wall 111. The first guide edge 113 can be integrally processed with the first annular wall 111, which can optimize the stress concentration problem at the connection position of the first plate 110 and the first annular wall 111. The first guide edge 113 fits against the second edge 122, thereby enabling a more stable connection between the first guide edge 113 and the second edge 122. The second edge 122, the first guide edge 113, the first annular wall 111, and the second annular wall 121 together form a support structure 130, which can further improve the structural strength and structural stability of the support structure 130, thereby further enhancing the load-bearing capacity of the support unit 100.

[0057] Reference Figure 3 As shown, in some embodiments of the present invention, the longitudinal section of the first guide edge 113 is arc-shaped. The arc-shaped structure of the first guide edge 113 can improve the connection strength between the first plate 110 and the first annular wall 111, effectively reducing stress concentration. It can be understood that the longitudinal section of the first guide edge 113 can be understood as a cross-section formed by cutting the first guide edge 113 with the plane containing the axis of the first annular wall 111. The longitudinal section of the second edge 122 is arc-shaped, matching the first guide edge 113. The arc-shaped structure of the second edge 122 can improve the connection strength between the second annular wall 121, effectively reducing stress concentration, and the second edge 122 provides better support for the first plate 110 and the first guide edge 113. It can be understood that the longitudinal section of the second edge 122 can be understood as a cross-section formed by cutting the second edge 122 with the plane containing the axis of the second annular wall 121.

[0058] Reference Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the first annular wall 111 is formed by deforming the first plate 110 toward the second plate 120, for example by stamping or other deformation methods. This deformation process improves the connection strength between the first annular wall 111 and the first plate 110, thereby increasing the structural strength of the first plate 110 and the first annular wall 111, and ultimately enhancing the load-bearing capacity of the support unit 100. One end of the first annular wall 111 is connected to the first plate 110, and the other end extends away from the first plate 110 and penetrates through the second plate 120. The first annular wall 111 penetrates through the second plate 120, forming a connecting hole 114 that passes between the first plate 110 and the second plate 120, thus creating multiple holes on the support unit 100. The design of these holes enables the support unit 100 to have a water-draining function, allowing it to be used in outdoor environments, increasing its service life, facilitating cleaning of the platform 1000, and also promoting ventilation of goods.

[0059] Reference Figure 3 As shown, it can be understood that in this embodiment, the inner diameter of the end of the first annular wall 111 away from the first plate 110 is larger than the inner diameter of the end closer to the first plate 110. That is, along the direction away from the first plate 110, the inner diameter of the cross-section of the first annular wall 111 gradually increases. It should be noted that, in order to achieve the above structure, the first annular wall 111 can be processed by extruding it outward, for example, by spreading or expanding the hole, etc., which are not specifically limited here. For example, the entire first annular wall 111 can be extruded, so that the inner diameter of the cross-section of the first annular wall 111 gradually increases from the end connected to the first plate 110 to the end away from the first plate 110; or the end of the first annular wall 111 away from the first plate 110 can be extruded, so that the inner diameter of the cross-section of a portion of the first annular wall 111 gradually increases. After the first ring wall 111 is compressed, the connection between the first ring wall 111 and the second ring wall 121 becomes stronger. Moreover, the first ring wall 111 and the second ring wall 121 form a tapered structure, which can prevent the second plate 120 from coming off the first plate 110, improve the structural stability of the support unit 100, and make the support unit 100 have higher structural strength and stronger load-bearing capacity.

[0060] Reference Figure 3As shown, it can be understood that the longitudinal section of the first annular wall 111 is inclined relative to its axis. Here, the longitudinal section of the first annular wall 111 can be understood as a cross-section formed by cutting the first annular wall 111 with the plane containing its axis. In this embodiment, by inclining the first annular wall 111, the first annular wall 111 and the second annular wall 121 form a tapered structure, which prevents the second plate 120 from detaching from the first plate 110, further improving the structural stability of the support unit 100. Moreover, the inclination angle ranges from 1 degree to 3 degrees. Within this parameter range, the manufacturing difficulty is low, and the structural stability of the support unit 100 is guaranteed.

[0061] Reference Figure 7 and Figure 8 As shown, it can be understood that the cross-sectional profile of the connecting hole 114 is circular, which simplifies the processing of the support unit 100 and improves its load-bearing capacity. The connecting holes 114 can be evenly distributed throughout the support unit 100, thereby achieving a better structural layout. In this embodiment, the inner diameter of the connecting holes 114 in the support unit 100 ranges from 35mm to 45mm, and the distance between the axes of adjacent connecting holes 114 ranges from 40mm to 60mm. Meeting these parameters allows for a better structural arrangement of the support structures 130 on the support unit 100 on the first plate 110 and the second plate 120. This enables the support unit 100 to distribute the load across each support structure 130 during load-bearing, reducing stress concentration and improving the load-bearing capacity of the support unit 100. Furthermore, the support unit 100 is easier to process and has a higher yield rate.

[0062] Reference Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the first annular wall 111 has a connecting hole 114, and the cross-sectional profile of the connecting hole 114 is circular. Therefore, both the first annular wall 111 and the second annular wall 121 are circular cylindrical structures, which makes the processing and assembly of the first plate 110 and the second plate 120 more convenient, reduces the difficulty of processing and assembly, and improves production efficiency. Of course, the cross-sectional profile of the connecting hole 114 can also be triangular, quadrilateral, hexagonal, etc., that is, the cross-sections of the first annular wall 111 and the second annular wall 121 are triangular, quadrilateral, hexagonal, etc., which are not specifically limited here. The support unit 100 using the above structure also has the advantages of high structural strength and strong load-bearing capacity.

[0063] Continue to refer to Figure 7 and Figure 8As shown, in some embodiments of the present invention, the first annular wall 111 is formed by stamping using a first plate 110. Directly stamping the first annular wall 111 using the first plate 110 simplifies the processing steps, improves production efficiency, and reduces metal usage, thus saving costs and reducing the weight of the support unit 100. In some embodiments of the present invention, the second annular wall 121 is formed by stamping using a second plate 120. Directly stamping the second annular wall 121 using the first plate 110 simplifies the processing steps, improves production efficiency, and reduces metal usage, thus saving costs and reducing the weight of the support unit 100.

[0064] Reference Figure 3 As shown, in some embodiments of the present invention, the lower end of the first annular wall 111 (i.e., the end away from the first plate 110) extends outward with a first edge 112, which can be formed by bending the first annular wall 111. The first edge 112 fits against the second plate 120 and is pressed against the second plate 120. The first edge 112 can be connected to the second plate 120 by pressing, welding, or riveting; the specific connection method is not specifically limited here. This makes the first annular wall 111 and the second annular wall 121 fit more closely and the connection is more secure, improving the structural strength of the support structure 130. Moreover, the first edge 112 can support the second plate 120 and the connection between the second plate 120 and the second annular wall 121, allowing the first annular wall 111 to more stably bear the load of the second plate 120, thereby improving the load-bearing capacity of the support unit 100.

[0065] Continue to refer to Figure 3 As shown, in some embodiments of the present invention, a second guide edge 123 is provided at the connection between the second plate 120 and the second annular wall 121. The second guide edge 123 can be integrally formed with the second annular wall 121, which can optimize the stress concentration problem at the connection position of the second plate 120 and the second annular wall 121. The second guide edge 123 fits against the first edge 112, thereby enabling a more stable connection between the second guide edge 123 and the first edge 112. The first edge 112 and the second guide edge 123, as well as the first annular wall 111 and the second annular wall 121, together form the support structure 130, which can further improve the structural strength and structural stability of the support structure 130, thereby further enhancing the load-bearing capacity of the support unit 100.

[0066] The second guide edge 123 has a groove 1231, and the first edge 112 engages with the groove 1231, making the connection between the first edge 112 and the second guide edge 123 more stable. The structure of the groove 1231 can be formed by pressing the first edge 112 onto the second guide edge 123, thereby compressing the second guide edge 123. This method is simpler and more convenient to manufacture, and the structure is more stable. Of course, the structure of the groove 1231 can also be achieved using other manufacturing methods.

[0067] Continue to refer to Figure 3 As shown, in some embodiments of the present invention, the lowest position of the first edge 112 is located in the plane of the second plate 120, thereby making the lower end surface of the support unit 100 a relatively smooth surface, avoiding hand injuries during handling, or interference with transport equipment (such as forklifts) leading to instability. Furthermore, the first edge 112 is flush with the second plate 120, resulting in a larger contact area, more uniform force distribution, and higher stability when the transport equipment supports the support unit 100.

[0068] Reference Figure 3 As shown, in some embodiments of the present invention, a cavity 140 is formed between the first plate 110 and the second plate 120. A support structure 130 formed by the first annular wall 111 and the second annular wall 121 is provided in the cavity 140, which can cooperate with the first plate 110 and the second plate 120 to support the shape of the cavity 140; and the support structure 130 makes the cavity 140 a sealed space to prevent foreign objects, such as water, from entering the cavity 140.

[0069] It should be noted that, in this embodiment of the invention, the depth of the cavity 140 is in the range of 12mm to 20mm. Within this range, the support structure 130 ensures that the support unit 100 has sufficient compressive strength, guaranteeing that the cavity 140 will not be deformed by compression, thereby making the support unit 100 more durable.

[0070] Reference Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the outer periphery of the first plate 110 is provided with a first folded edge 115, and the outer periphery of the second plate 120 is provided with a second folded edge 124. The first folded edge 115 and the second folded edge 124 are fixedly connected. The cooperative structure of the first folded edge 115 and the second folded edge 124 can close the edge of the support unit 100, preventing foreign objects from entering the cavity 140 from the edge of the support unit 100 through the gap between the first plate 110 and the second plate 120, thereby improving the stability of the support unit 100. It should be noted that the structure of the first folded edge 115 and the second folded edge 124 can be a connection structure commonly used on sheet metal parts, or a folded edge structure fixed by fasteners such as bolts, or a folded edge structure fixed by welding, riveting, etc., and is not specifically limited here.

[0071] Reference Figures 1 to 9 As shown, a platform 1000 according to an embodiment of the present invention includes the support unit 100 of the above embodiments. The embodiment of the present invention uses the support unit 100 of the first aspect embodiment. The support unit 100 comprises a first plate 110 and a second plate 120 arranged at intervals. A plurality of first annular walls 111 on the first plate 110 are correspondingly sleeved on the outer sides of a plurality of second annular walls 121 on the second plate 120, and the first annular walls 111 and second annular walls 121 are connected to achieve a tight connection between the first plate 110 and the second plate 120, improving the stability of the connection. The first annular walls 111 and second annular walls 121 are connected to form a support structure 130 for supporting the first plate 110 and the second plate 120. The support structure 130 is arranged at intervals between the first plate 110 and the second plate 120, and can combine with the first plate 110 and the second plate 120 to form a stable support unit 100, giving the platform 1000 the advantages of high structural strength and strong load-bearing capacity. Cavities are formed between the first plate 110 and the second plate 120, and within the supporting structure 130, which can effectively reduce the weight of the platform 1000 while ensuring the structural strength of the platform 1000.

[0072] Since the platform 1000 adopts all the technical solutions of the support unit 100 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0073] Reference Figure 6 As shown, in some embodiments of the present invention, the support unit 100 forms a pallet 200, which is formed by one or more support units 100. The bottom of the pallet 200 is provided with support feet 300, which support the pallet 200 and lift it off the bottom surface, thereby facilitating transport of the platform 1000 by forklifts or other transport vehicles. The support feet 300 can be made of metal, wood, or plastic. It is understood that the support feet 300 can be fixedly connected to the first plate 110 or the second plate 120.

[0074] Reference Figure 6 and Figure 9 As shown, in some embodiments of the present invention, the first plate 110 is provided with a third through hole 116 and a third annular wall 117. The third annular wall 117 is located on the outer periphery of the third through hole 116 and can be formed by stamping. The third annular wall 117 extends toward and abuts against the second plate 120, thereby supporting the first plate 110 on the second plate 120 through the third annular wall 117. Moreover, the third annular wall 117 seals the cavity 140, thereby preventing foreign objects from entering the cavity 140.

[0075] Continue to refer to Figure 9 As shown, the second plate 120 is provided with a fourth through hole 125 and a fourth annular wall 126. The fourth annular wall 126 is located on the outer periphery of the fourth through hole 125 and extends away from the first plate 110. The fourth annular wall 126 can be formed by stamping. The diameter of the third through hole 116 is larger than the diameter of the fourth through hole 125, thereby ensuring that the third annular wall 117 can stably support the second plate 120.

[0076] Continue to refer to Figure 9 As shown, the support leg 300 has an open and hollow structure at the top. The support leg 300 is fitted onto the fourth annular wall 126, making installation more convenient and lighter. The support leg 300 has a conical structure, and its outer diameter gradually decreases in the direction away from the support plate 200. The third through hole 116, the fourth through hole 125 and the upper end of the support leg 300 are connected, so that when the platform 1000 is placed, the support legs 300 of adjacent platform 1000s can nest with each other, so that the support plates 200 of adjacent platform 1000s can be stacked, thereby greatly reducing the space required for storing the platform 1000.

[0077] Reference Figure 9 As shown, in some embodiments of the present invention, the hollow support foot 300 includes a bottom wall 310 and a peripheral wall 320. One end of the peripheral wall 320 is connected to the bottom wall 310, making the connection of the support foot 300 more stable and increasing the friction of the contact surface of the support foot 300. The other end of the peripheral wall 320 is connected to the outer side of the fourth annular wall 126, making the connection between the support foot 300 and the support plate 200 more reliable and improving the connection reliability of the platform 1000.

[0078] It is understood that in some embodiments of the present invention, the end of the peripheral wall 320 away from the bottom wall 310 is provided with an installation edge 330, which abuts against the second plate 120, further improving the connection stability between the support foot 300 and the second plate 120, improving the installation efficiency of the support foot 300 and the second plate 120, and making the structure of the platform 1000 more reliable.

[0079] Continue to refer to Figure 9 As shown, the bottom wall 310 is provided with a fifth through hole 340, which is connected to the third through hole 116, the fourth through hole 125 and the inner cavity of the support foot 300, thereby realizing drainage between the contact surface of the first plate 110 and the support foot 300, preventing water from being trapped inside the support foot 300, and thus improving the service life of the platform plate 1000.

[0080] Continue to refer to Figure 9As shown, in some embodiments of the present invention, the support foot 300 is integrally manufactured, such as by stamping or injection molding, which makes the structure more stable, the processing simpler, the weight lighter, and the installation and replacement easier.

[0081] Reference Figure 6 As shown, in some embodiments of the present invention, the height between the bottom surface of the pallet 200 and the bottom surface of the support leg 300 is configured to allow the fork of a forklift to insert, thereby facilitating the transport of the platform 1000 by the forklift, improving transport efficiency and enhancing transport safety.

[0082] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
