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.

[0139] refer to Figure 1-7 This application provides a shelving device 100, including a shelving member 110, a horizontal support member 120, a vertical support member 130, and a structural support member 140.

[0140] The shelf member 110 is used to store items. The horizontal support member 120 is used to support the shelf member 110. The horizontal support member 120 includes a first crossbeam 121 and a second crossbeam 122 arranged laterally opposite each other. The vertical support member 130 is used to support the first crossbeam 121 and the second crossbeam 122. The vertical support member 130 includes a first column 131 and a second column 132 arranged laterally opposite each other.

[0141] The structural support member 140 includes a column strut 141 disposed between the first column 131 and the second column 132. The function of the structural support member 140 is to structurally reinforce the transverse support member 120 and the vertical support member 130.

[0142] Shelving units, such as shelves, are primarily sold as individual components. Consumers must assemble them themselves after purchasing the products. Currently, the assembly process requires at least two people to secure the uprights and support rods, or the uprights must be laid horizontally on the ground for assembly. This method is inconvenient for the average consumer.

[0143] This application provides a positioning mechanism 150 at one end of the column support rod 141. The positioning mechanism 150 can position one end of the column support rod 141 at a predetermined position on the first column 131, ensuring that the first column 131 and the column support rod 141 can be accurately assembled and positioned. In this way, the assembly personnel do not need to use their hands to support the work, improving work efficiency, and the operation process is simple and easy to implement.

[0144] refer to Figure 1-7 In one embodiment, a shelf assembly 100 includes a shelf member 110, a horizontal support member 120, a vertical support member 130, and a structural support member 140.

[0145] The shelving unit 100 is generally a frame structure composed of transverse support members 120 and vertical support members 130. "Vertical" refers to... Figure 1 The middle arrow X indicates the length direction of the frame structure; "lateral" refers to... Figure 1 The middle arrow Y indicates the width direction of the frame structure; "vertical" refers to... Figure 1 The middle arrow Z indicates the height direction of the frame structure; "upward" refers to the direction relative to the center. Figure 1 The direction is the same as the middle arrow Z; "downward" means in the same direction as... Figure 1 The direction opposite to the middle arrow Z.

[0146] The shelving component 110 can be one or more layers, used for storing items.

[0147] The shelf component 110 can be a shelf or a wire mesh shelf. A shelf is a plate-like structure made of metal or plastic, which has the advantage that items stored on it are less likely to fall off. A wire mesh shelf is a mesh composed of multiple longitudinal and transverse wires, which has the advantages of being lightweight and saving materials. Preferably, the longitudinal and transverse wires are metal steel wires. The wire mesh shelf is welded together from multiple longitudinal and transverse wires.

[0148] Accordingly, the lateral support member 120 may be one or more layers for supporting the support member 110. The lateral support member 120 may include a first crossbeam 121 and a second crossbeam 122 arranged laterally opposite each other. The first crossbeam 121 and the second crossbeam 122 have support surfaces for supporting the support member 110. The support surfaces of the first crossbeam 121 and the second crossbeam 122 are located on the same plane for supporting one layer of the support member 110.

[0149] The vertical support member 130 is used to support the horizontal beam 121. The vertical support member 130 may include a first column 131 and a second column 132 that are laterally opposite each other.

[0150] The structural support member 140 includes a column strut 141 disposed between the first column 131 and the second column 132. The column strut 141 may include a horizontal strut 142 and a diagonal strut 143. The horizontal strut 142 is horizontally disposed between the first column 131 and the second column 132. The diagonal strut 143 is diagonally disposed between the first column 131 and the second column 132; for example, one end of the diagonal strut 143 is disposed at the lower end of the first column 131, and the other end is disposed at the upper end of the second column 132. The column strut 141 can enhance the stability of the first column 131 and the second column 132.

[0151] Furthermore, the structural support member 140 also includes a crossbeam strut 144 disposed between the first crossbeam 121 and the second crossbeam 122. The crossbeam strut 144 can enhance the stability of the first crossbeam 121 and the second crossbeam 122.

[0152] One end of the column support rod 141 is equipped with a positioning mechanism 150. The positioning mechanism 150 can position one end of the column support rod 141 at a predetermined position on the first column 131, ensuring that the first column 131 and the column support rod 141 can be accurately assembled and positioned. In this way, the assembly personnel do not need to use both hands to support the work, improving work efficiency. The operation process is simple and easy to implement.

[0153] The other end of the column strut 141 can be accommodated in a first position in the first column 131 (e.g.) Figure 11 (as shown) and assembled to the second position of the second column (as shown) Figure 12 Switching between (as shown) facilitates the assembly of the column strut 141.

[0154] refer to Figure 11Taking the column support rod 141 as an example of a horizontal support rod, during the transportation and sales of the shelf assembly, one end of the column support rod 141 is positioned at a predetermined position on the first column 131, and a first hole 1311 can be opened at the predetermined position on the first column 131. The other end of the column support rod 141 rotates around the first hole 1311 on the first column 131 as a pivot axis, so that the column support rod 141 is accommodated in the first column 131, and the column support rod 141 is in a folded and hidden state. At this time, the column support rod 141 is in the first position.

[0155] refer to Figure 12 When the column support rod 141 needs to be assembled, the other end of the column support rod 141 rotates to a horizontal position with the first hole 1311 on the first column 131 as the pivot axis. The column support rod 141 is in a non-folded state, and its other end can be assembled to the second column. At this time, the column support rod 141 is in the second position.

[0156] In one embodiment, reference Figure 4 and Figure 7-12 The positioning mechanism 150 includes a first engaging member 151, which is elastic, for example, made of plastic. The first engaging member 151 is matched with the cross-sectional shape and size of the column support rod 141, and the first engaging member 151 can be engaged on the outside of one end of the column support rod 141.

[0157] The cross-section of the column support rod 141 is generally inverted U-shaped. The column support rod 141 includes a first bottom wall 1412 and two opposing first side walls 1413. A second hole 1411 is formed in the first side wall 1413 at one end of the column support rod 141.

[0158] The first connecting member 151 includes a second bottom wall 1511 and two opposing second side walls 1512. The first connecting member 151 also includes a first guide portion 1513, which is disposed on the inner side of the second bottom wall 1511 of the first connecting member 151. A first gap 1514 is formed between the first guide portion 1513 and the second side walls 1512 of the first connecting member 151. The first gap 1514 is consistent with the size of the first side wall 1413 of the column support rod 141, so that the first side wall 1413 of the column support rod 141 can be engaged between the first guide portion 1513 and the second side wall 1512 of the first connecting member 151.

[0159] The first guide portion 1513 has a third hole 1515, and the corresponding position of the second sidewall 1512 has a fourth hole 1516. When the first connector 151 is engaged with the first column 131, the first hole 1411, the second hole 1311, the third hole 1515, and the fourth hole 1516 are located on the same axis L1, and the column support rod 141 can be fixed together with the first column 131 by the first fastener 153. The first fastener 153 can be a bolt, screw, or pin.

[0160] The first guide section 1513 adopts a hole design, which facilitates the precise installation of bolts, screws and pins.

[0161] The positioning mechanism 150 also includes a second engaging member 152, which is elastic, for example, a leaf spring or a plastic part. The second engaging member 152 includes a first protrusion 1521 and a second protrusion 1522. A positioning hole 1312 is provided on the first column 131 at a position corresponding to the first protrusion 1521. The first protrusion 1521 and the positioning hole 1312 cooperate to position the second engaging member 152 at a predetermined position on the first column 131. The second protrusion 1522 is positioned towards the second sidewall 1512 of the first engaging member 151. When the other end of the column support rod 141 is in a first position received in the first column 131 (e.g., ...), ... Figure 11 (as shown) and assembled to the second position of the second column (as shown) Figure 12 When (as shown), the second protrusion 1522 can abut against one side of the first connector 151, so that the column support rod 141 can be positioned relative to the first column 131.

[0162] Traditionally, assembling the support rod 141 and the first column 131 requires manual alignment. Now, by using the first connector 151 and the second connector 152, the first column 131 and the support rod 141 can be positioned relative to each other, aligning their holes and facilitating the installation of fasteners. Specifically, the first connector 151 is assembled with one end of the support rod 141 (or pre-assembled), and the second connector 152 is assembled with the column 131 (or pre-assembled). The engagement of the first connector 151 and the second connector 152 allows for the positioning of the support rod 141 and the first column 131.

[0163] By providing a first guide portion 1513 on the first connecting member 151, which mates with the inverted U-shaped cross section of the column support rod 141, and by using a plastic part with a certain elasticity and an elastic part, such as a leaf spring, it is easier to achieve the interlocking of the concave and convex parts.

[0164] In one embodiment, reference Figure 9 and Figures 13a-13cThe positioning mechanism 150 includes a first engaging member 151, which is elastic, for example, made of plastic. The first engaging member 151 is matched with the cross-sectional shape and size of the column support rod 141, and the first engaging member 151 can be engaged on the outside of one end of the column support rod 141.

[0165] The first hole 1311 opened at the predetermined position of the first column 131 can be located on both sides of the first column 131.

[0166] The cross-section of the column support rod 141 is generally inverted U-shaped. The column support rod 141 includes a first bottom wall 1412 and two opposing first side walls 1413. Second holes 1411 are respectively opened on both sides of the first side wall 1413 at one end of the column support rod 141.

[0167] refer to Figure 13c The first connecting member 151 includes a second bottom wall 1511 and two opposing second side walls 1512. The first connecting member 151 also includes a first guide portion 1513, which is disposed on the inner side of the second bottom wall 1511 of the first connecting member 151. A first gap 1514 is formed between the first guide portion 1513 and the second side walls 1512 of the first connecting member 151. The first gap 1514 is consistent with the size of the first side wall 1413 of the column support rod 141, so that the first side wall 1413 of the column support rod 141 can be engaged between the first guide portion 1513 and the second side wall 1512 of the first connecting member 151.

[0168] The first guide portion 1513 has a third hole 1515, and the two second sidewalls 1512 have corresponding fourth holes 1516. When the first connector 151 is engaged with the first column 131, the first hole 1411, the second hole 1311, the third hole 1515 and the fourth hole 1516 are located on the same axis L1, and the column support rod 141 can be fixed together with the first column 131 by the first fastener 151.

[0169] In this embodiment, the first fastener 151 includes a riveting member 155 and a bolt 156. The riveting member 155 can be a rivet nut. The riveting member 155 passes sequentially through a second hole 1311 on one side of the first column 131 and a fourth hole 1516 on one side of the first connecting member 151. The first column 131 and the first connecting member 151 are fixed together by the riveting member 155. There is a third gap 1517 between the head of the riveting member 155 and the first guide portion 1513. The third gap 1517 is consistent with the size of the first side wall 1413 of the column support rod 141, so that the first side wall 1413 of the column support rod 141 can be engaged between the first guide portion 1513 and the head of the riveting member 155. The column support rod 141 is engaged in the first connector 151, and then the bolt 156 is passed through the second hole 1311 on the other side of the first column 131, the fourth hole 1516 on the other side of the first connector 151, and the third hole 1515 on the first guide part 1513 in sequence and screwed into the thread of the rivet 155, thereby fixing the column support rod 141 and the first column 131 together.

[0170] In one embodiment, reference Figure 14a and Figure 14b Taking the column support rod 141 as an example of a horizontal support rod, one end of the column support rod 141 is positioned at a predetermined position on the first column 131, and a first hole 1311 is provided at the predetermined position on the first column 131. The positioning mechanism 150 includes a third connecting member 154, which is elastic, for example, made of plastic. The third connecting member 154 includes a receiving part 1541 and a locking part 1542. One end of the receiving part 1541 matches the cross-sectional shape and size of the column support rod 141, and one end of the receiving part 1541 can be locked onto the outside of one end of the column support rod 141. The locking part 1542 can be vertically arranged at the other end of the receiving part 1541. In other embodiments, for example, when the column support rod 141 is a diagonal support rod, the engaging part 1542 can be obliquely arranged at the other end of the receiving part 1541, so that when the engaging part 1542 is positioned at a predetermined position of the first column 131, the angle of the receiving part 1541 is consistent with that of the column support rod 141 assembled to the second position of the second column.

[0171] refer to Figure 9 The cross-section of the column support rod 141 is generally inverted U-shaped. The column support rod 141 includes a first bottom wall 1412 and two opposing first side walls 1413. A second hole 1411 is provided on the first side wall 1413 at one end of the column support rod 141.

[0172] refer to Figure 14a and Figure 14bThe receiving part 1541 includes a third bottom wall 1543 and two opposing third side walls 1544. The receiving part 1541 also includes a second guide part 1545, which is disposed on the inner side of the third bottom wall 1543 of the receiving part 1541. A second gap 1546 is formed between the second guide part 1545 and the third side walls 1544 of the receiving part 1541. The second gap 1546 is consistent with the size of the first side wall 1413 of the column support rod 141, so that the first side wall 1413 of the column support rod 141 can be engaged between the second guide part 1545 and the third side wall 1544 of the receiving part 1541. The engaging portion 1542 includes a third protrusion 1547. A positioning hole 1312 is provided on the first post 131 at a position corresponding to the third protrusion 1547. The third protrusion 1547 and the positioning hole 1312 cooperate to position the engaging portion 1542 at a predetermined position on the first post 131.

[0173] The second guide portion 1545 has a fifth hole 1548, and the corresponding position of the third sidewall 1544 has a sixth hole 1549. When the third connector 154 is engaged with the first column 131, the first hole 1311, the second hole 1411, the fifth hole 1548, and the sixth hole 1549 are located on the same axis L2, and the column support rod 141 can be fixed together with the first column 131 by a first fastener. The first fastener can be a bolt, screw, or pin.

[0174] The second guide section 1545 adopts a hole design, which facilitates the precise installation of bolts, screws and pins.

[0175] In some embodiments, the column support rod 141 can directly contact and closely fit the column. For example, a concave-convex locking point is provided between the column support rod 141 and the column to achieve positioning, ensuring accurate installation and stable connection between the two.

[0176] refer to Figure 16 , 18 20. When the column support rod 141 needs to be assembled, one end of the column support rod 141 is located at a predetermined position on the first column 131, and the other end of the column support rod 141 can be assembled at a corresponding position on the second column. When the column support rod 141 is a horizontal support rod, the column support rod 141 is set horizontally so that the other end of the column support rod 141 can be connected to the corresponding position on the second column. At this time, the column support rod 141 is at the second position. When the column support rod 141 is a diagonal support rod, the column support rod 141 is set at an angle so that the other end of the column support rod 141 can be connected to the corresponding position on the second column. At this time, the column support rod 141 is at the second position.

[0177] In one embodiment, reference Figure 15-17The positioning mechanism 150 includes a corresponding fourth protrusion 1414 and a first recess 1313, which are respectively disposed on the column support rod 141 and the first column 131. When one end of the column support rod 141 is located at a predetermined position on the first column 131, and the other end of the column support rod 141 is located at a second position that allows assembly to the second column, the fourth protrusion 1414 and the first recess 1313 are in corresponding positions. During assembly, the column support rod 141 and the first column 131 are positioned by the cooperation of the fourth protrusion 1414 and the first recess 1313.

[0178] In one embodiment, reference Figure 18-19 The positioning mechanism 150 includes two fifth protrusions 1314 disposed on the first column 131. When one end of the column support rod 141 is located at a predetermined position on the first column 131 and the other end of the column support rod 141 is located at a second position that allows it to be assembled to the second column, the two fifth protrusions 1314 are respectively located on the upper and lower sides of one end of the column support rod 141. The two fifth protrusions 1314 can be formed by stamping. When the column support rod 141 is installed, the two fifth protrusions 1314 can perform a locking function, fixing the column support rod 141 at a predetermined height.

[0179] In one embodiment, reference Figure 20-21 The positioning mechanism 150 includes a protrusion 1315 disposed on the first column 131. When one end of the column support rod 141 is located at a predetermined position on the first column 131 and the other end of the column support rod 141 is located at a second position that allows it to be assembled to the second column, the protrusion 1315 is located below one end of the column support rod 141. The protrusion 1315 can be punched into an L-shape. During the installation of the column support rod 141, the protrusion 1315 can perform a locking function, fixing the column support rod 141 at a predetermined height.

[0180] In some embodiments, one end of the crossbeam support 144 is provided with a positioning mechanism, which can position one end of the crossbeam support 144 at a predetermined position on the first crossbeam 121. The other end of the crossbeam support 144 can switch between a third position accommodated in the first crossbeam 121 and a fourth position accommodated in the first crossbeam 121 and assembled to the second crossbeam 122. The structure and function of the positioning mechanism at one end of the crossbeam support 144 are similar to the structure and function of the positioning mechanism 150 at one end of the column support 141, and therefore will not be described again here.

[0181] In one embodiment, reference Figure 1-7 A shelf assembly 100 includes a shelf member 110, a horizontal support member 120, and a vertical support member 130.

[0182] The shelving unit 100 is generally a frame structure composed of horizontal support members 120 and vertical support members 130. The shelving members 110 can be one or more layers, used for storing items.

[0183] The shelf component 110 can be a shelf or a wire mesh shelf. A shelf is a plate-like structure made of metal or plastic, which has the advantage that items stored on it are less likely to fall off. A wire mesh shelf is a mesh composed of multiple longitudinal and transverse wires, which has the advantages of being lightweight and saving materials. Preferably, the longitudinal and transverse wires are metal steel wires. The wire mesh shelf is welded together from multiple longitudinal and transverse wires.

[0184] Accordingly, the lateral support member 120 may be one or more layers for supporting the support member 110. The lateral support member 120 may include a first crossbeam 121 and a second crossbeam 122 arranged laterally opposite each other. The first crossbeam 121 and the second crossbeam 122 have support surfaces for supporting the support member 110. The support surfaces of the first crossbeam 121 and the second crossbeam 122 are located on the same plane for supporting one layer of the support member 110.

[0185] The vertical support member 130 is used to support the horizontal beam 121. The vertical support member 130 may include a first column 131 and a second column 132 that are laterally opposite each other.

[0186] refer to Figure 22-25 The support component 110 can be folded laterally.

[0187] In one embodiment, reference Figure 22 The shelf component 110 includes a first shelf 111 and a second shelf 112. The first shelf 111 and the second shelf 112 are rotatably connected by a connecting part 113, which can be a hinge.

[0188] Wire mesh shelves are a common accessory for shelving systems, but they are bulky and inconvenient to transport and store. Foldable wire mesh shelves can be folded to a size no larger than the width of four uprights. The folded wire mesh shelves can be stacked together with uprights, beams, upright supports, beam supports, and other accessories, significantly reducing packaging volume and facilitating storage.

[0189] In one embodiment, reference Figure 23 and Figure 24 The support member 110 includes a first wire mesh shelf 114 and a second wire mesh shelf 115, which are rotatably connected by a connecting part 113. The first wire mesh shelf 114 and the second wire mesh shelf 115 include multiple longitudinal wires 116 and multiple transverse wires 117.

[0190] In one embodiment, reference Figure 25 The support member 110 includes a first wire mesh shelf 114, a second wire mesh shelf 115, and a third wire mesh shelf 118 connected in sequence, with each pair of wire mesh shelves rotatably connected by a connecting part 113. In other embodiments, the number of wire mesh shelves may exceed three.

[0191] In one embodiment, reference Figure 26 and 27 The connecting part 113 includes a first connecting piece 1131 and a second connecting piece 1132. The first connecting piece 1131 and the second connecting piece 1132 have opposite arc-shaped concave surfaces. The opposite arc-shaped concave surfaces can engage to form two grooves. The two grooves respectively cooperate with two adjacent longitudinal wires 116 in the first wire mesh shelf 114 and the second wire mesh shelf 115. The two longitudinal wires 116 are fixed and limited by the second fastener 1133 so that they will not detach in the two grooves.

[0192] In one embodiment, reference Figures 28-30 The connecting part 113 includes a connecting clip 1134 and a limiting clip 1135. The connecting clip 1134 is a hollow groove with an opening at the lower end. The limiting clip 1135 is a strip-shaped object that matches the internal shape and size of the connecting clip 1134. Notches are provided at the two upper corners of the limiting clip 1135. A locking block 1136 is provided on the limiting clip 1135. A locking groove 1137 is provided on the connecting clip 1134 at the position corresponding to the locking block 1136. When the limiting clip 1135 is inserted into the connecting clip 1134, the locking block 1136 engages with the locking groove 1137. A limiting space is formed between the connecting clip 1134 and the limiting clip 1135, which can accommodate two adjacent longitudinal wires 116 in the first wire mesh shelf 114 and the second wire mesh shelf 115.

[0193] In one embodiment, reference Figure 31 The connecting part 113 includes a first hook 1138 and a second hook 1139. The first hook 1138 and the second hook 1139 are connected to each other. The openings of the first hook 1138 and the second hook 1139 are arranged opposite to each other. The first hook 1138 cooperates with the longitudinal thread 116 in the first wire mesh shelf 114, and the second hook 1139 cooperates with the adjacent longitudinal thread 116 in the second wire mesh shelf 115, so that two adjacent longitudinal threads 116 will not detach from the first hook 1138 and the second hook 1139.

[0194] refer to Figure 32The transverse threads 117 of the first wire mesh shelf 114 and the second wire mesh shelf 115 are opposite each other. Due to insufficient gap in the connecting part 113, the gap δ between the transverse threads 117 is small, making it impossible for the first wire mesh shelf 114 and the second wire mesh shelf 115 to be fully folded upwards, but only downwards (as shown by the dashed arrow). Therefore, the size of the connecting part 113 is designed such that the gap δ between the transverse threads 117 at the connection of the first wire mesh shelf 114 and the second wire mesh shelf 115 is sufficient to allow the first wire mesh shelf 114 and the second wire mesh shelf 115 to be fully folded upwards.

[0195] In one embodiment, reference Figure 33 The transverse wires 117 in the first wire mesh shelf 114 extend to form a third hook 1140. The third hook 1140 engages with the adjacent longitudinal wires 116 in the second wire mesh shelf 115, so that the longitudinal wires 116 will not come off within the third hook 1140.

[0196] In one embodiment, reference Figures 34-38 Two transverse wires 117 in the first wire mesh shelf 114 extend, bend, and close to form a first bend 1141. Two transverse wires 117 in the second wire mesh shelf 115 extend, bend, and close to form a second bend 1142. The shapes of the first bend 1141 and the second bend 1142 are matched so that the first bend 1141 and the second bend 1142 can be engaged together, so that the first wire mesh shelf 114 and the second wire mesh shelf 115 will not separate.

[0197] The first bend 1141 and the second bend 1142 can adopt any shape known to those skilled in the art that can be matched with each other. In this embodiment, a transverse wire 117 in the first wire mesh shelf 114 extends laterally to form a first part 11411, bends downward to form a second part 11412, bends longitudinally to form a third part 11413, bends upward to form a fourth part 11414, and then closes with a fifth part 11415 extending laterally from another transverse wire 117 to form the first bend 1141. One transverse wire 117 in the second wire mesh shelf 115 extends laterally to form a sixth part 11421, bends downward to form a seventh part 11422, retracts and bends upward to form a first latching part 11423, bends longitudinally to form an eighth part 11424, bends downward and extends to form a second latching part 11425, bends upward to form a ninth part 11426, and then closes with a tenth part 11427 extending laterally from another transverse wire 117 to form a second bend 1142. The first latching part 11423 and the second latching part 11425 in the second wire mesh shelf 115 can cooperate with the third part 11413 in the first wire mesh shelf 114, so that the first wire mesh shelf 114 and the second wire mesh shelf 115 will not detach.

[0198] In one embodiment, reference Figure 38 A first bend 1141 and a second bend 1142 may be sequentially provided on a longitudinal edge 119 of the first wire mesh shelf. A second bend 1142 and a first bend 1141 may be sequentially provided on the corresponding longitudinal edge 119 of the second wire mesh shelf. Each first bend 1141 in the first wire mesh shelf mates with a corresponding second bend 1142 in the second wire mesh shelf, and each second bend 1142 in the first wire mesh shelf mates with a corresponding first bend 1141 in the second wire mesh shelf.

[0199] In one embodiment, reference Figures 39-44 The support member 110 can be folded and stacked laterally with the column 131 and the beam 121. In this embodiment, the overall width W after stacking is between 370mm and 420mm.

[0200] After being folded, the shelving component 110 roughly matches the width of the four uprights 131 and the four crossbeams 121. The shelving component 110, uprights 131, and crossbeams 121 can be stacked into a uniform package, thereby reducing transportation costs and packaging volume.

[0201] In one embodiment, reference Figure 39 A connector 1210 is provided at each end of the crossbeam 121. The two ends of the crossbeam 121 can be detachably connected to the adjustment holes 1316 of different heights on the column 131 through the connectors 1210.

[0202] In one embodiment, reference Figure 45 The crossbeam 121 is long and thin, and its cross section is generally C-shaped, including a side plate 1211 and two opposing upper flanges 1212 and lower flanges 1213.

[0203] The upper wing plate 1212 has a support surface 1214 for supporting the mounting member.

[0204] The side plates 1211 at both ends of the crossbeam 121 extend to form connectors 1210. The two ends of the crossbeam 121 can be detachably connected to the adjustment holes 1316 at different heights on the column 131 through the connectors 1210.

[0205] To achieve structural reinforcement of the crossbeam, the crossbeam in this application adopts a variety of shapes and profiles.

[0206] In some embodiments, reference Figure 46-63 The upper wing plate 1212 is also provided with an abutment surface 1215 for abutting against the support member 110. The abutment surface 1215 can be perpendicular to the support surface 1214, or it can form an angle greater than 90 degrees and less than 180 degrees with the support surface 1214.

[0207] The lower wing plate 1213 can be vertical and flush with the side plate 1211, or it can be symmetrically arranged with the upper wing plate 1212.

[0208] The side panel 1211 has a reinforcing structure, which may include a third bend 1216 that bends inward or outward. The third bend 1216 can be reset after bending, so that the side panel 1211 is generally on one plane. Alternatively, the third bend 1216 may not be reset after bending, so that the side panel 1211 is generally on two planes.

[0209] In one embodiment, reference Figure 46 The crossbeam 121 is elongated and has a generally C-shaped cross-section, comprising a side plate 1211 and two opposing upper flanges 1212 and lower flanges 1213. The upper flange 1212 has a support surface 1214 for supporting the supporting member. A first abutment surface 1215 for abutting against the supporting member 110 is also provided on the upper flange 1212. The first abutment surface 1215 is perpendicular to the support surface 1214. The lower flange 1213 is perpendicular to and flush with the side plate 1211. The side plate 1211 has a reinforcing structure, including an inwardly bent third bend 1216. The third bend 1216 returns to its original position after bending, such that the side plate 1211 is generally on a single plane. Preferably, there are two symmetrical third bends 1216.

[0210] In one embodiment, reference Figure 47 ,and Figure 46Similarly, the difference lies in that the lower wing plate 1213 and the upper wing plate 1212 are symmetrically arranged. The lower wing plate 1213 has a bottom surface 1217 that is symmetrical to the supporting surface 1214.
