Description

Technical Field

[0001] This utility model relates to the field of storage rack technology, and in particular to a shelf longitudinal beam and the shelf itself. Background Technology

[0002] Shelving is widely used in warehousing and logistics activities. Most existing shelving structures are composed of columns, longitudinal beams, transverse beams, and shelves. They are typically arranged vertically at intervals with multiple layers. The spaces between layers are often used to classify and store goods, so that various items can be quickly and accurately retrieved.

[0003] However, in the existing structure, because the longitudinal beams are slender members, the cross-sectional structure design of the longitudinal beams is not reasonable enough, resulting in insufficient structural strength, which limits the load-bearing capacity of the entire shelf, and the longitudinal beams are prone to bending deformation.

[0004] Secondly, the shelving system also has the following disadvantages: 1. The longitudinal beam cross-section is unreasonable, resulting in insufficient load-bearing capacity and bending resistance. Material thickness needs to be increased to meet users' medium-to-heavy-duty storage needs. However, increased material thickness leads to increased product weight and cost, resulting in less price competitiveness and increased logistics costs for e-commerce sales. 2. The columns use a multi-segment structure design, making it inconvenient to connect and install adjacent column units. 3. The structural design is relatively complex, making it difficult to adjust the spacing between shelves according to usage requirements or to add or remove shelves as needed. 4. The structural design is not reasonable enough, failing to adequately balance lightweight design requirements with load-bearing design requirements.

[0005] Therefore, how to design a longitudinal beam with a more reasonable cross-sectional structure, which can better improve the load-bearing capacity of the longitudinal beam, facilitate the disassembly and assembly of the column unit to adjust the shelf height, facilitate the adjustment of the shelf spacing and number of shelves, and better meet both lightweight design requirements and load-bearing design requirements, has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to design a longitudinal beam with a more reasonable cross-sectional structure, which can better improve the load-bearing capacity of the longitudinal beam, make it easier to operate and disassemble the column unit to adjust the shelf height, make it easier to adjust the shelf spacing and number of shelves, and make the shelf longitudinal beam and shelf frame that better meet both the requirements of lightweight design and load-bearing design.

[0007] To achieve the above objectives, this utility model provides a shelf longitudinal beam, comprising a longitudinal beam plate with an overall elongated strip structure; the longitudinal beam plate includes upper and lower longitudinal bars arranged vertically at intervals, with an inclined longitudinal bar between the upper and lower longitudinal bars, the upper side of the inclined longitudinal bar being bent outward horizontally to form a longitudinal support bar, and the outer side of the longitudinal support bar being connected to the lower side of the upper longitudinal bar, and the lower side of the inclined longitudinal bar being connected to the upper side of the lower longitudinal bar; characterized in that; the lower side of the lower longitudinal bar is curled upward toward the inner side to form a curled reinforcing edge with an arc-shaped cross-section; and a reinforcing rib groove arranged longitudinally is recessed on the outer surface of the inclined longitudinal bar.

[0008] Thus, in the aforementioned tiered longitudinal beam structure, the longitudinal beam plate structure includes upper longitudinal bars, lower longitudinal bars, inclined longitudinal bars, and longitudinal support bars. The overall cross-sectional design is more rational, resulting in better bending resistance and improved structural strength. Furthermore, integrating the upper longitudinal bars, lower longitudinal bars, inclined longitudinal bars, and longitudinal support bars into a single molding design further enhances structural strength. Secondly, a curled reinforcing edge is provided on the lower side of the lower longitudinal bar, and reinforcing rib grooves are provided on the outer surface of the inclined longitudinal bars. This makes the cross-sectional design of the lower and inclined longitudinal bars more rational, allowing each to reinforce the structure, further improving the overall structural strength, bending resistance, and load-bearing capacity of the longitudinal beams.

[0009] As a preferred option, the cross-sectional structure of the curled reinforcing edge is designed as a semi-circular structure.

[0010] In this way, the structural design of the curled reinforcing edge is simpler, more reasonable, and easier to process and manufacture.

[0011] Preferably, the reinforcing rib grooves are two arranged at intervals along the width direction of the inclined longitudinal strip.

[0012] In this way, the design of the number of reinforcing rib grooves is more reasonable.

[0013] Preferably, the radius of the outer contour of the curled reinforcing edge is 5 mm.

[0014] In this way, the size design of the curled reinforcing edge is more reasonable and easier to process and manufacture.

[0015] Preferably, the cross-section of the reinforcing rib groove is designed with a circular arc shape, and the radius of the outer contour of the reinforcing rib groove is 1mm.

[0016] In this way, the structure and size design of the reinforcing rib groove are more reasonable, making it easier to process and shape.

[0017] Preferably, the ends of the longitudinal support strip and the inclined longitudinal strip are each provided with a chamfered structure, so that a V-shaped notch is formed between the ends of the longitudinal support strip and the inclined longitudinal strip.

[0018] In this way, by setting a V-shaped notch between the ends of the longitudinal support bars and the ends of the inclined longitudinal bars, the entire structure can be processed and formed more easily.

[0019] Preferably, a circular hole is provided at the end of both the upper and lower longitudinal strips.

[0020] This makes installation and use much easier.

[0021] As a preferred option, the longitudinal beams are obtained by roll forming.

[0022] This makes the longitudinal beams more integrated and easier to process and manufacture.

[0023] Preferably, the upper side of the curled reinforcing edge is provided with a rounded corner structure.

[0024] This reduces the number of sharp parts on the longitudinal beams.

[0025] This technical solution also discloses a shelf, characterized in that it includes longitudinal beams with the above-mentioned structure.

[0026] In summary, the above-mentioned longitudinal beam structure has the advantages of a more reasonable longitudinal beam cross-sectional design, which can better improve the load-bearing capacity of the longitudinal beam. Attached Figure Description

[0041] like Figures 1 to 4 As shown, a shelf longitudinal beam includes a longitudinal beam plate 24 with an overall elongated strip structure design; the longitudinal beam plate includes upper longitudinal bars 29 and lower longitudinal bars 30 arranged vertically at intervals, an inclined longitudinal bar 31 is provided between the upper and lower longitudinal bars, the upper side of the inclined longitudinal bar is bent outward horizontally to form a longitudinal support bar 32, and the outer side of the longitudinal support bar is connected to the lower side of the upper longitudinal bar, and the lower side of the inclined longitudinal bar is connected to the upper side of the lower longitudinal bar; the lower side of the lower longitudinal bar is curled upward toward the inner side to form a curled reinforcing edge 100 with an arc-shaped cross-section design; and a reinforcing rib groove 101 arranged longitudinally is recessed on the outer surface of the inclined longitudinal bar.

[0042] Thus, in the aforementioned tiered longitudinal beam structure, the longitudinal beam plate structure includes upper longitudinal bars, lower longitudinal bars, inclined longitudinal bars, and longitudinal support bars. The overall cross-sectional design is more rational, resulting in better bending resistance and improved structural strength. Furthermore, integrating the upper longitudinal bars, lower longitudinal bars, inclined longitudinal bars, and longitudinal support bars into a single molding design further enhances structural strength. Secondly, a curled reinforcing edge is provided on the lower side of the lower longitudinal bar, and reinforcing rib grooves are provided on the outer surface of the inclined longitudinal bars. This makes the cross-sectional design of the lower and inclined longitudinal bars more rational, allowing each to reinforce the structure, further improving the overall structural strength, bending resistance, and load-bearing capacity of the longitudinal beams.

[0043] In this specific embodiment, the cross-sectional structure of the curled reinforcing edge is designed as a semi-circular structure.

[0044] In this way, the structural design of the curled reinforcing edge is simpler, more reasonable, and easier to process and manufacture.

[0045] In this specific embodiment, the reinforcing rib grooves are two arranged at intervals along the width direction of the inclined longitudinal strip.

[0046] In this way, the design of the number of reinforcing rib grooves is more reasonable.

[0047] In this specific embodiment, the radius of the outer contour of the curled reinforcing edge is 5mm.

[0048] In this way, the size design of the curled reinforcing edge is more reasonable and easier to process and manufacture.

[0049] In this specific embodiment, the cross-section of the reinforcing rib groove is designed with an arc shape, and the radius of the outer contour of the reinforcing rib groove is 1mm.

[0050] In this way, the structure and size design of the reinforcing rib groove are more reasonable, making it easier to process and shape.

[0051] In this specific embodiment, the ends of the longitudinal support bar and the inclined longitudinal bar are each provided with a chamfered structure, so that a V-shaped notch is formed between the ends of the longitudinal support bar and the inclined longitudinal bar.

[0052] In this way, by setting a V-shaped notch 102 between the ends of the longitudinal support bars and the ends of the inclined longitudinal bars, the entire structure can be processed and formed more easily.

[0053] In this specific embodiment, a circular hole 103 is provided at the ends of the upper and lower longitudinal strips.

[0054] This makes installation and use much easier.

[0055] In this specific embodiment, the longitudinal beam is obtained by roll forming.

[0056] This makes the longitudinal beams more integrated and easier to process and manufacture.

[0057] In this specific embodiment, a rounded corner structure is provided on the upper side of the curled reinforcing edge end.

[0058] This reduces the number of sharp parts on the longitudinal beams.

[0059] like Figures 5 to 13 As shown in the figure, this specific embodiment discloses a shelf, including the longitudinal beams of the above-described structure.

[0060] In this specific embodiment, it also includes a shelf body, which includes four vertical columns 1 that are rectangularly distributed in the horizontal direction; the columns include multiple vertically arranged column units 2 that are arranged end to end, and the opposite ends of two adjacent column units are connected by a connecting member 3; the column unit has an L-shaped plate structure design in cross section, and the connecting member includes a connecting plate 4 with an L-shaped cross section, such that the two inner sides of the connecting plate are respectively attached to the two outer sides of the column unit; the two sides of the connecting plate are bent inward to form limiting strips 5 that are attached to the edges of the two inner sides of the column unit; and a horizontally inwardly arranged support block 6 is provided on each of the two inner sides of the connecting plate, the support block is located between two column units, and the two opposite column units abut against the upper and lower surfaces of the support block.

[0061] In this way, the structural design of the connecting components in the above-mentioned rolled rivet column shelf is simpler and more reasonable. This makes the two adjacent column units more stable and reliable after being connected, and also makes it easier to disassemble and assemble them. This makes it easier to operate the column units to disassemble and assemble in order to adjust the shelf height.

[0062] In this specific embodiment, multiple abutment protrusions 7 are provided vertically at intervals on the inner side of the limiting strip, and the two sets of abutment protrusions abut and support each other at the two inner side edges of the column unit.

[0063] In this way, by setting multiple abutment protrusions on the inner side of the limiting strip, it can better abut and support the inner edge of the column unit, and better connect and cooperate the column unit.

[0064] Furthermore, the abutment boss is formed by stamping on the outer surface of the limiting strip. This makes processing and manufacturing more convenient.

[0065] In this specific embodiment, the middle positions of the two outer sides of the docking plate are each drawn inward and each forms an inwardly protruding support portion 8 on the two inner sides of the docking plate. The column unit is provided with an inwardly recessed mating groove 9 corresponding to the support portion, so that the inner sides of the support portion are respectively supported in the mating grooves on the two outer sides of the column unit.

[0066] This design makes the fit between the docking plate and the column unit more reasonable, and better prevents rotation and tilting between the two after the column unit and the docking plate are fitted together.

[0067] In this specific embodiment, each of the two outer sides of the docking plate is provided with a rectangular opening 10 that extends through the thickness direction, and the lower edge of the rectangular opening is bent inward to form the support block.

[0068] This makes it easier to process and form support blocks on the mating plate.

[0069] In this specific embodiment, the two sides of the docking plate are bent inward to form an arc-shaped edging 11, and the outer side of the edging is bent and extended to form the limiting strip.

[0070] In this way, the structural design of the docking plate is simpler and more reasonable, and it is easier to process and shape it into a limiting strip.

[0071] In this specific embodiment, the column unit includes a first upright plate 12 and a second upright plate 13 arranged at right angles to each other; each of the outer surfaces of the first upright plate and the second upright plate has a plurality of vertically spaced first mounting holes 14 and second mounting holes 15. The first mounting holes and the second mounting holes are designed with a waist-shaped hole structure and are arranged in the vertical direction. Each of the first mounting holes and the second mounting holes has a first clearance hole 16 and a second clearance hole 17 at its upper end, such that the diameter of the first clearance hole is larger than the diameter of the first mounting hole, and the diameter of the second clearance hole is larger than the diameter of the second mounting hole. The diameter setting also includes multiple vertically spaced shelf unit layers 18, with each of the four corner positions of the shelf unit layer forming a first mating surface 19 and a second mating surface 20. A first fixing rivet 21 and a second fixing rivet 22 are respectively connected and fixed on the first mating surface and the second mating surface, such that the rivet heads of the first fixing rivet and the second fixing rivet can respectively pass through the first clearance round hole and the second clearance round hole, and the rivet rods of the first fixing rivet and the second fixing rivet can respectively cooperate and be supported at the lower end of the first mounting hole and the second mounting hole.

[0072] In this way, the design of the cooperation between the column unit and the shelf unit is simpler and more reasonable, making it easier to disassemble and assemble the shelf unit and to adjust the shelf unit height as needed.

[0073] Furthermore, both the first and second fixing rivets are arranged in pairs vertically. This improves the stability of the shelving unit after assembly.

[0074] In this specific embodiment, the shelf unit includes a long strip-shaped horizontal beam plate 23 and a longitudinal beam plate 24; each end of the horizontal beam plate forms a first mating surface, and each end of the longitudinal beam plate forms a second mating surface; the horizontal beam plate includes an upper horizontal bar 25 and a lower horizontal bar 26 arranged vertically at intervals, with an inclined horizontal bar 27 between the upper and lower horizontal bars, the upper end of the inclined horizontal bar being bent outward horizontally to form a transverse support bar 28, and the outer side of the transverse support bar being connected to the lower side of the upper horizontal bar, and the lower side of the inclined horizontal bar being connected to the lower horizontal bar, such that... The upper surface of the transverse support bar forms a first mounting support surface; the longitudinal beam plate includes an upper longitudinal bar 29 and a lower longitudinal bar 30 arranged vertically at intervals, an inclined longitudinal bar 31 is provided between the upper and lower longitudinal bars, the upper end of the inclined longitudinal bar is bent outward horizontally to form a longitudinal support bar 32, and the outer side of the longitudinal support bar is connected to the lower side of the upper longitudinal bar, the lower side of the inclined longitudinal bar is connected to the lower longitudinal bar, and the upper surface of the longitudinal support bar forms a second mounting support surface; it also includes a shelf 33, and the shelf overlaps the first support plane and the second support plane around its perimeter.

[0075] In this way, the structural design of the shelving unit is simpler and more reasonable. When assembling the shelving unit to the four columns, the horizontal and vertical beams can be assembled first, followed by the shelving panels, making the entire assembly simpler and more convenient. Secondly, the structural design of the horizontal and vertical beams is simpler and more reasonable, better meeting the requirements of lightweight design, and also providing better strength to meet the load-bearing requirements.

[0076] In this specific embodiment, the upper horizontal bar, lower horizontal bar, inclined horizontal bar, and transverse support bar are integrally formed; the upper vertical bar, lower vertical bar, inclined vertical bar, and longitudinal support bar are integrally formed.

[0077] In this way, the structural design of the longitudinal and transverse beams is more reasonable and easier to process and manufacture.

[0078] In this specific embodiment, end caps 34 are provided at both the upper and lower ends of the column.

[0079] In this way, by designing the end cap, the design becomes more reasonable.

[0080] In summary, the above-mentioned shelving system features a simpler and more reasonable structural design, easier assembly and disassembly of the column units to adjust the shelving height, easier adjustment of the spacing between shelves and the number of shelves, and a better balance between lightweight and load-bearing design requirements.
