The portions of the clamping plates (200) passing through the slots (3100) can be used to be in close proximity to the limiting surfaces (10), so that when subjected to external pressure, the support bars (2) can be pressed against the limiting surfaces (10) by means of the clamping plates (200), thereby enhancing the resistance of the support bars (2) to bending deformation.

Description

A shelf and storage system

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 1, 2024, with application number 202420403145.5 and invention name “A Shelf and Storage System”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of storage systems, and in particular to a shelf and a storage system. Background Art

[0003] Shelves are often used in warehousing systems to store bins. These shelves typically form a support frame with columns and beams, with shelves or crossbeams placed on the crossbeams to create storage spaces for the bins. Shelf structures are large, costly, and difficult to transport and install. Therefore, in recent years, crossbeams and crossbeams have generally been used to form storage spaces. In the related art, crossbeams are typically mounted on crossbeams using welding, threading, or clamping. While welding and threading solutions offer high stability, they are difficult to assemble on site, especially for taller shelves, where welding or threading are particularly challenging. Clamping crossbeams to crossbeams, on the other hand, presents a relatively poor stability issue. This is especially true if a bin is accidentally impacted, as this can easily cause the clamping connection between the crossbeam and crossbeam to fail and the crossbeam to detach. Furthermore, slots in the crossbeams reduce the crossbeam's structural strength, weakening its load-bearing capacity and making them unsuitable for applications with heavier bins. Summary of the Invention

[0012] Optionally, one of the plug board and the vertical plate is provided with a bayonet, and the other is provided with a buckle, and the buckle is configured to be able to be locked into the bayonet when the plug board is inserted into the socket.

DETAILED DESCRIPTION

[0037] To make the objectives, technical solutions, and advantages of this application more clearly understood, the present application is further described below with reference to the accompanying drawings and examples. It is apparent that the described examples are only a portion of the embodiments of this application, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the examples in this application are intended to fall within the scope of protection of this application.

[0038] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described in the embodiments are intended to be used to explain the present application and are not to be construed as limiting the present application.

[0039] References in this specification to "one embodiment," "an example," or "an example" mean that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment disclosed herein. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

[0040] To facilitate the assembly of the crossbeams and horizontal beams in a rack, some related art solutions install adapters on the horizontal beams, provide slots on the adapters, and provide snap-fitting portions at the ends of the crossbeams that fit into the slots. The snap-fitting portions snap into the slots to complete the assembly. However, this solution has the following problems: while the snap-fitting structure maintains a certain degree of stability between the snap-fitting portions and the inner walls of the slots, in certain situations (such as when a material box accidentally falls off during placement, causing a strong impact on the crossbeam), a long structural member like the crossbeam will experience significant bending deformation, which can easily cause the snap-fitting portions at both ends of the crossbeam to disengage from the slots, causing the crossbeam to separate from the horizontal beam.

[0041] This embodiment provides a shelf, as shown in Figures 1 to 3a, Figure 1 is a structural schematic diagram of a shelf provided in the embodiment of the present application, Figure 2a is a schematic diagram of the use status of the shelf provided in this embodiment, Figure 2b is a structural schematic diagram of the column piece in Figure 1, and Figure 3a is an assembly schematic diagram of the cross beam 2 and the cross beam 1 in this embodiment. The shelf includes two cross beams 1 arranged at intervals, a connecting member 3 fixed on the cross beam 1, and a cross beam 2 installed between the two cross beams 1 through the connecting member 3, and the cross beam 2 includes a top wall 20 and side walls 21 located on the left and right sides of the top wall 20 along the length direction of the top wall 20.

[0042] As shown in Figures 4 and 8, Figure 4 is an enlarged schematic diagram of part A in Figure 3a, and Figure 8 is an enlarged schematic diagram of part C in Figure 7. A card plate 200 is formed at the end of the top wall 20, and an insert plate 210 is formed at the end of the side wall 21, and a limiting surface 10 for abutting against the card plate 200 is formed on the side surface of the cross beam 1 facing the cross beam 2; the connecting member 3 is formed with a through hole 3100 for the card plate 200 to pass through and a socket 3101 for the insert plate 210 to be inserted, the card plate 200 passes through the through hole 3100, and along the length direction of the cross beam 2, the spacing between the card plate 200 and the limiting surface 10 is smaller than the spacing between the card plate 200 and the inner wall surface of the through hole 3100.

[0043] By fixing the connecting member 3 on the crossbeam 1 and providing a socket 3101 on the connecting member 3, the plug-in plate 210 on the crossbeam 2 cooperates with the socket 3101 to achieve plug-in connection, avoiding the need to directly process grooves on the crossbeam 1, thereby avoiding affecting the structural strength of the crossbeam 1. At the same time, a perforation 3100 is provided on the connecting member 3, and a clamping plate 200 is provided on the crossbeam 2. The portion of the clamping plate 200 passing through the perforation 3100 is close to the limit surface 10. In this way, when the crossbeam 2 is subjected to external pressure (normal material box placement or accidental impact of the material box), the clamping plate 200 can be pressed against the limit surface 10, thereby preventing the crossbeam 2 from generating large bending deformation. In this way, the load-bearing capacity of the crossbeam 2 can be improved, and the crossbeam 2 is not easily separated from the crossbeam when encountering an accidental impact.

[0044] As shown in Figures 1 to 2b, the shelf is a detachable assembly structure, including column pieces located on both sides of the shelf, including columns 4, cross braces 7, and diagonal braces 6. The columns 4, cross braces 7, and diagonal braces 6 are fastened together with screws to form a whole, used to support the entire structure. As shown in Figures 3a to 3c, Figure 3b is a schematic assembly diagram of the crossbeam 1 and connecting member 3 in this embodiment, and Figure 3c is an enlarged schematic diagram of portion E in Figure 3b. The shelf includes two spaced crossbeams 1, connecting members 3 fixed to the crossbeams 1, and a crossbeam 2 installed between the two crossbeams 1 via the connecting member 3. In this embodiment, the crossbeams 1 are arranged via the columns 4. Specifically, the crossbeams 1 are hung or screwed to the columns 4 via bolts, and the crossbeams 1 and columns 4 cooperate to form a stable frame structure. A number of crossbeams 2 are arranged on the two crossbeams 1 arranged at intervals on the same layer, forming storage spaces between adjacent crossbeams 2. When the shelf is used, the material box 5 can be placed in the above storage spaces.

[0045] 4, 5, 6, and 8, FIG5 is a schematic diagram of the structure of the cross beam 2 in this embodiment, and FIG6 is an enlarged schematic diagram of portion B in FIG5. The cross beam 2 in this embodiment includes a top wall 20 and side walls 21 located on the left and right sides of the top wall 20 along the length direction of the top wall 20. A clamping plate 200 is formed at the end of the top wall 20, and a plug plate 210 is formed at the end of the side wall 21. A limiting surface 10 for contacting the clamping plate 200 is formed on the side surface of the cross beam 1 facing the cross beam 2. The connecting member 3 is formed with a through hole 3100 for the clamping plate 200 to pass through and a socket 3101 for inserting the plug plate 210. When assembling the cross beam 2 and the cross beam 1, the plug plate 210 at the end of the cross beam 2 is aligned with the socket 3101 on the connecting member 3 and inserted, and the clamping plate 200 can pass through the through hole 3100.

[0046] As shown in Figures 7 and 8, Figure 7 is a cross-sectional view of the structure of the span beam 2 through the connecting member 3 and the cross beam 1, and Figure 8 is an enlarged schematic diagram of part C in Figure 7. After the span beam 2 and the cross beam 1 are assembled, the clamping plate 200 on the span beam 2 is close to the side surface of the cross beam 1 facing the span beam 2. Specifically, along the length direction of the span beam 2, the spacing between the clamping plate 200 and the limiting surface 10 will be smaller than the spacing between the clamping plate 200 and the inner wall surface of the through hole 3100.

[0047] The rack provided in this embodiment is provided with a connecting member 3 fixed on the crossbeam 1 and a socket 3101 provided on the connecting member 3, and the plug plate 210 on the crossbeam 2 is used to cooperate with the socket 3101 to achieve plugging, thereby avoiding direct processing of grooves on the crossbeam 1, thereby avoiding affecting the structural strength of the crossbeam 1. At the same time, a perforation 3100 is provided on the connecting member 3, and a clamping plate 200 is provided on the crossbeam 2, and the portion of the clamping plate 200 passing through the perforation 3100 is close to the limit surface 10. In this way, when the crossbeam 2 is subjected to external pressure (normal placement of the material box 5 or accidental impact of the material box 5), the crossbeam 2 will deform. When the crossbeam 2 is slightly deformed, the clamping plate 200 on the crossbeam 2 will press against one side of the crossbeam 1, thereby limiting the crossbeam 2 from further bending deformation. In this way, the bearing capacity of the crossbeam 2 can be improved, and the crossbeam 2 is not easy to separate from the crossbeam 1 when encountering an accidental impact.

[0048] It should be noted that, as shown in FIG8 , there is a gap between the clip 200 and the limiting surface 10 in this embodiment, and the size of this gap is smaller than the size of the gap between the clip 200 and the inner wall of the perforation 3100. This allows the clip 200 to abut against the limiting surface 10 after the cross beam 2 undergoes a slight bending deformation. It is easy to understand that the formation of the limiting surface 10 on the side surface of the cross beam 1 facing the cross beam 2 in this embodiment for abutting the clip 200 does not necessarily mean that the clip 200 will abut against the limiting surface 10 after the cross beam 2 and the cross beam 1 are assembled. Instead, when the cross beam 2 bends and deforms after bearing weight, it will cause the clip 200 to move slightly, causing the clip 200 to abut against the limiting surface 10. Of course, in an alternative embodiment, the clip can also be made to abut against the limiting surface 10 after the cross beam and the cross beam are assembled. However, in this case, the dimensional processing accuracy requirements of the cross beam, connecting member, and cross beam components are higher.

[0049] It is easy to understand that the through hole 3100 in this embodiment is configured to be in a rectangular shape that matches the card plate 200 .

[0050] In this embodiment, the clamping plate 200 is designed to be parallel to the limiting surface 10, while the inserting plate 210 intersects the limiting surface 10. Specifically, the inserting plate 210 is designed to be perpendicular to the limiting surface 10. This design allows the clamping plate 200 to achieve surface-to-surface contact with the limiting surface 10, while the end surface of the inserting plate 210 facing the limiting surface 10 can also contact the limiting surface 10 when the span beam 2 bends and deforms. This further enhances the bending resistance of the span beam 2.

[0051] As shown in Figures 9 and 10, Figure 9 is a schematic diagram of the structure of the connecting member 3 in this embodiment, and Figure 10 is a schematic diagram of the structure of the connecting member 3 in this embodiment from another perspective. In this embodiment, the connecting member 3 includes a bottom plate 30, a connecting plate 31, and two vertical plates 32, which are formed into an integral body. The connecting plate 31 includes a top plate 310, and the two vertical plates 32 are located between the top plate 310 and the bottom plate 30, and the top plate 310 and the bottom plate 30 are both located between the two vertical plates 32. The aforementioned perforations 3100 and sockets 3101 are both provided on the connecting plate 31, and the top plate 310 cooperates with the vertical plates 32 to limit the position of the insert plate 210 along the length of the beam 1. That is, after the insert plate 210 is inserted into the socket 3101, the top plate 310 and the vertical plates 32 cooperate to limit the insert plate 210 along the length of the beam 1, preventing the span beam 2 from shaking along the length of the beam 1. In this embodiment, the bottom plate 30, the connecting plate 31, and the two vertical plates 32 are formed as one piece, which means that the connecting member 3 is manufactured as a whole by a one-time stamping process, which is convenient for mass production. In an alternative embodiment, the bottom plate, the connecting plate, and the vertical plates can also be welded together by a process such as welding.

[0052] Furthermore, the connecting plate 31 in this embodiment also includes a vertical plate 311 that is bent relative to the top plate 310, with a through-hole 3100 provided on the top plate 310, and a socket 3101 formed between the connecting plate 31 and the vertical plate 32. Specifically, one end of the vertical plate 311 is fixed to the top plate 310, and the other end of the vertical plate 311 is fixed to the side end of the bottom plate 30 away from the crossbeam 1. Along the length direction of the crossbeam 1, the front and rear ends of the connecting plate 31 are spaced apart from the vertical plate 32 on the corresponding side to form the socket 3101. In this solution, the vertical plate 311 is used to fix the top plate 310 and the bottom plate 30 together, and the space between the top plate 310 and the vertical plate 32 is used to form the socket 3101 for inserting the plug 210. Therefore, when the connecting member 3 provided in this embodiment is used to assemble the span beam 2 and the cross beam 1, the insert plate 210 can be inserted into the socket 3101 along the top-to-bottom direction (i.e., along the thickness direction of the span beam 2), or the insert plate 210 can be inserted into the socket 3101 along the length direction of the span beam 2.

[0053] With this structure, the connecting member 3 can be formed with the required through-holes 3100 and the bayonet 2100. Furthermore, the connecting member 3 can be fixedly connected to the crossbeam 1 via the connecting plate 31. The connecting plate 31 can be secured to the crossbeam 1 by welding or by bolting. Because the connecting member 3 is relatively small, pre-installing it on the crossbeam 1 will not hinder transportation of the crossbeam 1.

[0054] In an optional embodiment, the aforementioned vertical plates may not be provided, but the connecting plate and the vertical plates may be directly fixed together (not shown in the figure), and then the required socket structure may be provided at the connection between the connecting plate and the vertical plates.

[0055] 3a, 4, and 8, to prevent the provided connecting member 3 from affecting the bearing capacity of the span beam 2, the structural design of the connecting member 3 in this embodiment allows the end of the span beam 2 to overlap with the connecting member 3 over a larger area, thereby providing more stable vertical support for the span beam 2 by the connecting member 3. Specifically, an overlapping surface 201 is formed at the end of the top wall 20 of the span beam 2, and the top wall 20 overlaps the top plate 310 via the overlapping surface 201.

[0056] In conjunction with Figures 6, 10, 11, and 12b, Figure 11 is an enlarged schematic diagram of portion D in Figure 3a, Figure 12a is a diagram illustrating the coupling structure in an embodiment of the present application, and Figure 12b is an enlarged schematic diagram of portion F in Figure 12a. In this embodiment, a snap-fit ​​structure is further provided between the insert plate 210 and the riser 32. This snap-fit ​​structure allows for a tighter connection between the crossbeam 2 and the crossbeam 1. Specifically, the snap-fit ​​structure includes a snap-fit ​​notch 2100 provided on the insert plate 210 and a snap-fit ​​320 provided on the riser 32. The snap-fit ​​320 is configured to snap into the snap-fit ​​notch 2100 when the insert plate 210 is inserted into the socket 3101. It will be readily understood that in other optional embodiments, the snap-fit ​​notch can also be provided on the riser, and the snap-fit ​​can be provided on the insert plate accordingly. During assembly, the insert plate is inserted into the socket. Once the insert plate is properly inserted, the snap-fit ​​automatically snaps into the snap-fit ​​notch. To remove the span beam 2 from the crossbeam 1, the sidewalls 21 of the span beam 2 can be squeezed from both sides to deform the insert plate 210, thereby disengaging the latch 2100 on the insert plate 210 from the latch 320 on the riser 32, allowing the span beam 2 to be removed smoothly. In this embodiment, an opening is provided in the riser 32, and the inner wall of the opening forms a spring structure protruding from the riser 32. This spring structure is the latch 320. It will be readily understood that the shape of the latch is not limited to the structure shown in this embodiment.

[0057] The connecting member 3 may be made of metal and fixed to the crossbeam 1 by welding.

[0058] To enhance the load-bearing capacity of the span beam 2, a flange 211 is provided at the bottom of the span beam 2 in this embodiment. Specifically, as shown in Figures 5 and 6 , the side wall 21 of the span beam 2 in this embodiment has a flange 211 extending along the length of the span beam 2 at the end facing away from the top wall 20. However, in this embodiment, the flange 211 does not extend below the insert plate 210, which allows the size of the socket 3101 to be designed to be smaller. For ease of description, the side wall 21 can be described as comprising a middle section and edge sections at either end of the middle section (it will be readily understood that the middle section and the edge sections form a continuous, integrated structure), with the insert plate 210 formed by the edge sections. In this embodiment, the flange 211 extends to the junction of the middle section and the edge sections. That is, as previously described, the flange 211 does not extend below the insert plate 210. However, in other optional embodiments, as shown in Figure 13, which is a schematic diagram of the end structure of the span beam 2 in an optional embodiment, the convex edge 211 can also be designed to extend to the end surface of the side wall 21, that is, the convex edge 211 will extend to the bottom of the plug plate 210. In this way, the size of the socket needs to be designed to be larger so that the convex edge can be inserted from the socket. Alternatively, when adopting the solution in which the connecting plate includes a top plate and a vertical plate in this embodiment, a notch for the convex edge to extend into can be provided on the portion of the vertical plate near the bottom plate, so that the size of the socket formed between the top plate and the vertical plate does not need to be changed. When sampling this solution, the span beam needs to be inserted into the socket between the connecting plate and the vertical plate along its own length direction during assembly.

[0059] In addition, the shelf provided in this embodiment can be used in a warehousing system, which includes multiple rows of the shelves provided in this embodiment, and a lane for transportation equipment to pass through is formed between two adjacent rows of the shelves.

Those skilled in the art should understand that the present application includes but is not limited to the contents described in the drawings and the above specific embodiments.
