[0035] The present application will be further described in detail below with reference to the drawings and specific embodiments.

[0036] As shown in FIGS. 1 to 4, the present application discloses a connection structure for a beam and a column. Specifically, it is a connection structure between a beam 200 and a column 100, which can be applied to a rack, shelf, or cabinet. The connection structure includes at least two positioning holes and two connecting plates. The column 100 is provided with the at least two positioning holes 101 along a vertical direction. Two ends of the beam 200 are respectively connected to the two connecting plates 201. Each connecting plate 201 is provided with at least two positioning elements 202 along the vertical direction. Any two adjacent positioning elements of the at least two positioning elements of each connecting plate are configured to be respectively matched and inserted into any two adjacent positioning holes of the at least two positioning holes to keep a position of the beam 200 on the column 100.

[0037] As shown in FIGS. 1, 2, 3 and 4, the column 100 and the beam 200 are both formed by integrally bending metal sheets. A cross section of the column 100 is rectangular. Additionally, the cross section of the column 100 may be other polygons. The column 100 includes a first surface 107 and a second surface 108, which are adjacent to each other. The first surface 107 may be an outer side surface, which faces no other columns, of the column 100. The at least two positioning holes 101 are disposed on the first surface 107 of the column 100 and along the vertical direction for various height choices of the beam 200. The user can adjust the height of the beam 200 according to the sizes of the items to be stored.

[0038] In some embodiments, the connecting plate 201 is fixedly connected to the end of the beam 200 by welding. Each connecting plate is provided with two positioning elements formed by bending the connecting plate, the two positioning elements both being perpendicular to the connecting plate. Specifically, each connecting plate 201 includes a first plate 208 and a second plate 209 that are adjacent. The first plate 208 and the second plates 209 are two parts, which are formed by bending, of an integrally bent structure.The first plate 208 and the second plate 209 are respectively attached to the first surface 107 and the second surface 108 of each column 100. The second plate 209 is welded and fixed to the end of the beam 200.In some embodiments, the connecting plate may be integrally formed with the beam.

[0039] To facilitate the insertion of the positioning elements 202 on the connecting plate 201 into the positioning holes 101 on the column 100, the positioning holes 101 are provided on the first surface 107, and the positioning elements 202 are provided on the first plate 208. Specifically, the two positioning elements 202 of each connecting plate 201 are formed by bending the connecting plate 201. The two positioning elements 202 are respectively provided at the upper and lower ends of the first plate 208 , and each positioning element 202 is arranged perpendicular to the connecting plate 201, namely: the connecting plate is arranged vertically and the positioning element is arranged horizontally. The two positioning elements 202 are provided at the upper and lower ends of the first plate 208, so that the positioning elements 202 can be formed by being bent directly in a bending mold, improving processing convenience.

[0040] In order to facilitate processing and reduce processing costs, in some embodiments, the positioning holes 101 are rectangular through holes, and the positioning elements 202 are configured as plate-shaped or square-shaped positioning elements 202 that can be matched and inserted into the positioning holes 101.

[0041] Specifically, the first plate 208 and the second plate 209 of the connecting plate 201 may be perpendicular to each other, and the first surface 107 and the second surface 108 of the column 100 may be perpendicular to each other. To install the beam 200 on the column 100, the first plate 208 of the connecting plate 201 is held parallel to the first surface 107 of the column 100, and then the connecting plate 201 is actuated to move perpendicular to the first surface 107 of the column 100. These operations allow the positioning elements 202 on the first plate 208 to be easily inserted into the positioning holes 101 on the first surface 107 of the column 100, making installation simple and convenient.

[0042] In order to make the connection between the column 100 and the beam 200 more secure and stable, and to improve the load-bearing capacity of the beam 200, as shown in FIGS. 3 and 4, the connecting plate 201 is fastened to the column 100 by a fastener 3. Specifically, the connecting plate 201 at the end of the beam 200 is installed on the column 100 with the positioning elements 202 inserted into the positioning holes 101, and then the connecting plate 201 is fastened to the column 100 by the fastener 3. In this way, the load-bearing capacity of the beam 200 is shared by the insertion structure of the positioning elements 202 and the positioning holes 101 and the fastener 3, thereby enhancing the load-bearing capacity of the beam 200. Furthermore, the fastener 3 can keep the position of the connecting plate 201 to the column 100, thereby making the connection structure between the connecting plate 201 and the column 100 more stable and secure. When adjusting the height of the beam 200 or disassembling the beam 200, the connecting plate 201 can be easily removed from the column 100 by simply removing the fastener 3, thereby making the height adjustment or disassembly of the beam 200 very convenient and labor-saving.

[0043] In an implementation, the fastener 3 is a connecting screw that fastens the connecting plate 201 and the column 100. After passing through the connecting plate 201 and the column 100, the connecting screw is locked by a nut. Specifically, at least one connecting screw for each connecting plate 201 is configured to be locked with the column 100, thereby achieving a stable connection between the connecting plate 201 and the column 100. For example, as shown in FIGS. 3 and 4, the connecting plate 201 is provided with a connecting hole 210, and the column 100 is provided with a mounting hole 102 corresponding to the connecting hole 210. After the positioning elements 202 are inserted into the positioning holes 101, the connecting hole 210 and the mounting hole 102 coincide with each other, and then the fastener 3 is mounted in the connecting hole 210 and the mounting hole 102, thereby fastening the connecting plate 201 to the column 100.

[0044] In some embodiments, the fastener 3 may also be a pin tightly fitted with the mounting hole, or a bolt directly threadedly connected to a screwed mounting hole, etc. In some embodiments, the fastener may also be a hoop that can lock the connecting plate to the column, etc. In some embodiments, a plurality of fasteners may be used to fasten the column 100 and the connecting plate 201, or one or more other linkage structures, such as snap-fit structures, magnetic coupling structures, may be used to fasten the two. Additionally, the numbers and types for linkage structures or fasteners between different columns 100 and the connecting plates 201 may be different or the same.

[0045] Specifically, the connecting hole 210 is disposed on the first plate 208 of the connecting plate 201, and the mounting hole 102 is disposed on the first surface 107 of the column 100, with the mounting hole 102 being located between two adjacent positioning holes 101. After the positioning elements 202 of the connecting plate 201 are inserted into the positioning holes 101 on the column 100, the connecting hole 210 on the connecting plate 201 will correspond to and coincide with the mounting hole 102 on the column 100, facilitating the installation of the fastener 3. In other words, the insertion and matching of the positioning elements 202 with the positioning holes 101 provide a positioning function, thereby enabling quick alignment of the connecting hole 210 and the mounting hole 102.

[0046] The mounting hole 102 being located between two adjacent positioning holes 101, may mean that the height of the mounting hole 102 is between the heights of the two adjacent positioning holes 101. Specifically, the mounting hole 102 may be located on a connecting line of the two adjacent positioning holes 101, or may be located offset from the connecting line of the two positioning holes 101.

[0047] As shown in FIGS. 5 to 10, the present application discloses a storage rack including a frame 1 and at least one shelf assembly 2 connected to the frame 1. The frame 1 includes a column 100, and each shelf assembly 2 includes a beam 200. The connection structure for a beam and a column of any of the above-mentioned embodiments is adopted to connect the column 100 and the beam 200. The load-bearing capacity of the shelf assembly 2 is enhanced by the beam 200, because the load-bearing capacity of the beam 200 is shared by the positioning element 202, the positioning hole 101, and the fastener(s) 3. Furthermore, the fastener 3 is used to position the connecting plate 201 of the beam 200 of the shelf assembly 2 raletive to the column 100, thereby making the connection structure between the connecting plate 201 and the column 100 more stable and firm, thereby making the connection structure between the shelf assembly 2 and the frame 1 more stable and firm.

[0048] As shown in FIGS. 5, 6, and 7, the storage rack includes at least two frames 1 and at least one shelf assembly 2. Each frame 1 includes two columns 100 arranged along the width of the rack. A first horizontal rod 103 and a second horizontal rod 104, distributed along the vertical direction, are connected between the two columns 100. An inclined supporting rod 105 is connected between the first horizontal rod 103 and the second horizontal rod 104. The shelf assembly 2 is disposed between the two columns 100 and includes a storage plate 203 connected to the beam 200.

[0049] As shown in FIGS. 5, 6, and 7, an elongated opening is disposed on a side surface of each column 100. Specifically, for each frame 1, the two openings of the two columns 100 are arranged opposite each other. A pair of connecting bases 106 are connected in two inner spaces of two upper portions of the two columns 100 of each frame 1 through the two openings. The first horizontal rod 103 is connected between the connecting bases 106. A pair of connecting bases 106 are connected in two inner spaces of two lower portions of the two columns 100 of each frame 1 through the two openings. The second horizontal rod 104 is connected between the connecting bases 106. The support rod 105 is arranged in a inclined manner, with an upper end of the inclined supporting rod 105 connected to the first horizontal rod 103, and a lower end of the inclined supporting rod 105 connected to the second horizontal rod 104. The two columns 100 are connected to form a stably connected frame 1 by the first horizontal rod 103, the second horizontal rod 104, and the inclined supporting rod 105.

[0050] In order to facilitate the installation of the shelf assembly 2 with the frame 1, as shown in FIG. 9, each end of each beam 200 of the shelf assembly 2 is connected with a connecting plate 201, and each connecting plate 201 is provided with two positioning elements 202 that are respectively matched with the two positioning holes 101 on the corresponding column 100. After the positioning elements 202 on the connecting plates 201 at both ends of the beam 200 are respectively inserted into the positioning holes 101 on the two columns 100 on the same side of the two frames 1, each connecting plate 201 is fastened to the column 100 by a fastener 3.

[0051] As shown in FIGS. 7, 8 and 9, each column 100 has multiple positioning holes 101 evenly spaced along its height, with mounting holes 102 located between two adjacent positioning holes 101. Each shelf assembly 2 includes two beams 200. Two connecting plates 201 at both ends of the beam 200 on a front side of the storage rack are connected to two columns 100 on a front side of the two frames 1, respectively. Two connecting plates 201 at both ends of the beam 200 on a rear side of the storage rack are connected to two columns 100 on a rear side of the two frames 1, respectively. A spacing between the two positioning elements 202 on each connecting plate 201 is equal to a spacing between every two adjacent positioning holes 101. After the positioning elements 202 on the connecting plate 201 are inserted and positioned into the positioning holes 101 on the column 100, fasteners 3 are mounted through the connecting holes 210 on the connecting plate 201 and the mounting holes 102 on the column 100, and the connecting plate 201 is kept with an expected position to the column 100 using the nuts corresponding to the fasteners 3.

[0052] In some embodiments, the storage rack may include more than two frames 1. Each column 100 of each frame 1 has two groups of positioning holes 101, which are symmetrically distributed along a width of each column 100. Each group of positioning holes 101 includes multiple positioning holes 101 evenly spaced along the height of the corresponding column. Such arrangements facilitate the simultaneous installation of shelf assemblies 2 on both sides of the frame 1, allowing an extension of the length of the storage rack. FIG. 7 shows a single-section storage rack. For a two-section rack, the shelf assemblies 2 may be installed on both sides of the central frame 1.

[0053] In the relevant technology, butterfly holes are adopted on the column to facilitate the clampings of the fixing blocks. The butterfly holes are generally oblique holes with a large opening at the upper end and a small opening at the lower end. After the fixing blocks are clamped into the butterfly holes, the pressure of the weight of the goods on the shelf makes the fixing blocks and the lower ends of the butterfly holes clamped very tightly, which makes the height adjustment and disassembly of the shelf assembly very laborious and inconvenient to operate. Different from the above arrangements, in some embodiments of the present application, when adjusting the height of the shelf assembly 2 or disassembling the shelf assembly 2, it is only necessary to remove the fastener(s) 3 to easily remove the connecting plate 201, so that the height adjustment or disassembly of the shelf assembly 2 is very convenient and labor-saving.

[0054] In some embodiments, all the positioning elements on the connecting plate may be disposed on the second plate, and the connecting holes for the fasteners may be disposed on the first plate of the connecting plate.

[0055] The shelf assembly 2 is an assembled structure, including at least one pair of beams 200, and each pair of beams includes two beams respectively disposed at two opposite edges of the shelf assembly 2. Two groups of sockets 207 are respectively disposed at the two beams of each pair of beams correspondingly. A plurality of supporting rods are mounted between two beams of each pair of beams, and two plugs 206 are respectively disposed at two ends of each supporting rods 205, and the two plugs are configured to be respectively matched and inserted into a pair of sockets 207 on one pair of beams 200. In one possible implementation, as shown in FIGS. 9 and 10, each shelf assembly 2 includes two beams 200 and a metal mesh storage plate 203 connected to the two beams 200. Multiple supporting rods 205 are positioned between the two beams 200. With such arrangements, to assemble the shelf assembly 2, the two beams 200 are first mounted at an expected position on the columns 100 of the two frames 1 respectively, with the connecting plates 201 at the ends of the beams 200 connected to the columns 100 through the fasteners 3, while ensuring that the two beams 200 are at the same horizontal height; the plugs 206 at both ends of the supporting rod 205 are then respectively inserted into one pair of sockets 207 on the two beams 200; after the supporting rods 205 are all assembled, the metal mesh storage plate is placed to cover the supporting rods 205 with its four corners of fixed to the two beams 200 with screws.

[0056] As the shelf assembly 2 is also a metal component and is relatively heavy, if the shelf assembly 2 is assembled with the frame 1 as a whole, it will require the cooperation of at least two people to complete the assembly, which is a laborious process. With the above arrangements, the shelf assembly 2 allows the beams 200 of the shelf assembly 2 to be assembled with the frame 1 at first, and then the supporting rods 205 and storage plate 203 of the shelf assembly 2 are assembled in order. This makes the assembly between the shelf assembly 2 and the frame 1 more labor-saving and can be easily completed by only one person.

[0057] Furthermore, the four corners of the metal mesh are provided with mounting plates 204, which are configured to be fixed to the beams 200 by screws. This arrangement makes the connection between the storage plate 203 and the beam 200 more firm and stable.
