[0057] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0058] See also Figure 1 The present embodiment provides a switching box, comprising a base frame 100, a front wall 200 erected on the front side of the base frame 100, side walls 300 erected on the left and right sides of the base frame 100, a top plate 400 covering the front wall 200 and the side walls 300, and a rear door 500 hinged at the rear end of the side wall 300. The switching box of the present embodiment further comprises a bottom side beam 600 and a bottom front beam 700. The base frame 100 and the side walls 300 are connected by the bottom side beam 600, and the base frame 100 and the front wall 200 are connected by the bottom front beam 700.

[0059] The exchange box is an assembled structure. Before assembly, the base frame 100, front wall 200, side wall 300, top plate 400, rear door 500, bottom side beam 600 and bottom front beam 700 are all loose parts, so as to facilitate transportation in the form of loose parts. After being transported to the destination, they are assembled at a different location to form a complete exchange box. The front wall 200, side wall 300, rear door 500, bottom side beam 600 and bottom front beam 700 constitute the vertical structure above the base frame 100. When describing the front, back, top, bottom, side, inside, outside and other directions below, the use state of the exchange box is used as a reference.

[0060] The chassis 100 is an important component of the exchange box, which is the main load-bearing structure of the exchange box and provides vertical connection surfaces on the front, rear, left and right sides of the outer side for mounting the front wall 200, the side wall 300 and the rear door 500 on the chassis 100. The chassis 100 and each facade structure are transported separately as loose parts and connected as a whole at the destination using fasteners, glue, or fasteners plus glue.

[0061] See also Figure 2 The chassis 100 includes a chassis body 110, an angle piece 120 fixed to the bottom of the chassis body 110, a first reinforcement piece 130 fixed to the chassis body 110 corresponding to the angle piece 120, and a leg 140 installed at the bottom of the chassis body 110. The leg 140 can be folded up and down, wherein when the chassis 100 is transported as loose parts, the leg 140 is folded relative to the chassis body 110. The specific shape and connection structure of the leg 140 can refer to the structure of the leg in the related art. Figure 1 A floor 150 is also laid on the base frame body 110 . The floor 150 , as a part of the base frame 100 , is fixedly connected to the base frame body 110 .

[0062] In this embodiment, the chassis body 110 includes a bottom longitudinal beam 111 arranged longitudinally, a plurality of bottom cross beams 115 arranged transversely, a front end beam 112 transversely welded to the front end of the bottom longitudinal beam 111, a rear end beam 113 transversely welded to the rear end of the bottom longitudinal beam 111, and two bottom side beams 114 longitudinally connected between the end of the front end beam 112 and the end of the rear end beam 113. In this embodiment, there are two bottom longitudinal beams 111, the two bottom longitudinal beams 111 are arranged at intervals, the bottom cross beam 115 is vertically connected to the bottom longitudinal beam 111, the bottom cross beam 115 is arranged at intervals along the length direction of the bottom longitudinal beam 111, and the two ends of the bottom cross beam 115 are connected to the bottom side beam 114.

[0063] The front end beam 112 is used to connect the bottom front beam 700 so as to connect the front wall 200 with the bottom frame 100 .

[0064] See also Figure 4 The front end beam 112 includes a horizontal upper wing plate 1121, a first vertical plate 1122 bent vertically downward from the inner side of the upper wing plate 1121, a floor bearing plate 1123 bent horizontally inward from the lower end of the first vertical plate 1122, a web 1124 bent vertically downward from the outer side of the upper wing plate 1121, and a lower wing plate 1125 bent horizontally outward from the lower end of the web 1124.

[0065] Furthermore, the upper surface of the upper wing plate 1121 of the front end beam 112 constitutes the top surface 1126 of the front end beam 112, and the top surface 1126 is horizontal. The upper surface of the floor bearing plate 1123 of the front end beam 112 constitutes the floor bearing surface 1127 of the front end beam 112, and the floor bearing surface 1127 is horizontal. The outer surface of the web 1124 of the front end beam 112 constitutes the connecting surface 1128 of the front end beam 112, and the connecting surface 1128 is vertically arranged.

[0066] The floor bearing surface 1127 of the front end beam 112 extends toward the bottom longitudinal beam 111 to support the floor 150 together with the bottom longitudinal beam 111; the floor bearing surface 1127 of the front end beam 112 is lower than the top surface 1126 of the front end beam 112, and the height interval between the two is no greater than the thickness of the floor 150, so that the height of the top surface 1126 of the front end beam 112 is no higher than the upper surface of the floor 150.

[0067] The connection surface 1128 of the front beam 112 is lower than the top surface 1126 of the front beam 112, and is located outside the top surface 1126 of the front beam 112, and is used to connect with the facade structure of the exchange box through fasteners or glue. Specifically, the connection surface 1128 of the front beam 112 is used to connect with the bottom front beam 700, so that the front wall 200 is installed on the bottom frame 100 when the exchange box is assembled.

[0068] When the front end beam 112 is connected to the bottom front beam 700, the rear side surface of the bottom front beam 700 is attached to the connection surface 1128 of the front end beam 112, and the bottom end of the bottom front beam 700 is supported above the lower wing plate 1125 of the front end beam 112. The upper surface of the lower wing plate 1125 of the front end beam 112 is lower than the height of the top surface 1126 of the front end beam 112, so that it is not easy for moisture to enter the top surface 1126 through the lower wing plate 1125, thereby effectively preventing rainwater from entering the exchange box.

[0069] The rear end beam 113 is used to connect the rear door 500 so as to connect the rear door 500 to the bottom frame 100 .

[0070] See also Figure 3 and Figure 5 The rear end beam 113 includes a horizontal upper wing plate 1131, a first vertical plate 1132 bent vertically downward from the inner side of the upper wing plate 1131, a floor bearing plate 1133 bent horizontally inward from the lower end of the first vertical plate 1132, a web 1134 bent vertically downward from the outer side of the upper wing plate 1131, and a lower wing plate 1135 bent horizontally inward from the lower end of the web 1134.

[0071] Furthermore, the upper surface of the upper wing plate 1131 of the rear end beam 113 constitutes the top surface 1136 of the rear end beam 113, and the top surface 1136 is horizontal. The upper surface of the floor bearing plate 1133 of the rear end beam 113 constitutes the floor bearing surface 1137 of the rear end beam 113, and the floor bearing surface 1137 is horizontal. The two ends of the rear end beam 113 exchange box in the horizontal direction constitute the connection surface 1138 of the rear end beam 113, and the connection surfaces 1138 at the two ends of the rear end beam 113 are vertically arranged.

[0072] The floor bearing surface 1137 of the rear end beam 113 extends toward the bottom longitudinal beam 111 so as to be used together with the bottom longitudinal beam 111 to bear the floor; the floor bearing surface 1137 of the rear end beam 113 is lower than the top surface 1136 of the rear end beam 113, and the height interval between the two is no greater than the thickness of the floor 150, so that the height of the top surface 1136 of the rear end beam 113 is no higher than the upper surface of the floor 150.

[0073] The connection surface 1138 of the rear end beam 113 is lower than the top surface 1136 of the rear end beam 113, and the connection surface 1138 of the rear end beam 113 is used to connect with the facade structure of the exchange box through fasteners or glue. Specifically, the connection surface 1138 of the rear end beam 113 is used to connect with the rear door 500, so that when the exchange box is assembled, the rear door 500 is installed on the chassis 100. The rear end beam 113 has vertical closing plates (not numbered in the figure) at both ends along the width direction of the exchange box. The outer surface of the closing plate constitutes the connection surface 1138, and the closing plate is provided with a through hole so as to be connected with the rear door 500.

[0074] The bottom edge beam 114 is used to connect the bottom side beam 600 so as to connect the side wall 300 to the bottom frame 100 .

[0075] See also Figure 6 The bottom edge beam 114 includes a horizontal upper wing plate 1141, a first vertical plate 1142 bent vertically downward from the inner side of the upper wing plate 1141, a floor bearing plate 1143 bent horizontally inward from the lower end of the first vertical plate 1142, a web 1144 bent vertically downward from the outer side of the upper wing plate 1141, and a lower wing plate 1145 bent horizontally outward from the lower end of the web 1144.

[0076] Further, the upper surface of the upper wing plate 1141 of the bottom side beam 114 constitutes the top surface 1146 of the bottom side beam 114, and the top surface 1146 is horizontal. The upper surface of the floor bearing plate 1143 of the bottom side beam 114 constitutes the floor bearing surface 1147 of the bottom side beam 114, and the floor bearing surface 1147 is horizontal. The outer surface of the web plate 1144 of the bottom side beam 114 constitutes the connecting surface 1148 of the bottom side beam 114, and the connecting surface 1148 is vertically arranged.

[0077] The floor bearing surface 1147 of the bottom edge beam 114 extends toward the bottom longitudinal beam 111 so as to be used together with the bottom longitudinal beam 111 to bear the floor 150 ; the floor bearing surface 1147 of the bottom edge beam 114 is lower than the top surface 1146 of the bottom edge beam 114 , and the height interval therebetween is no greater than the thickness of the floor 150 , so that the height of the top surface 1146 of the bottom edge beam 114 is no higher than the upper surface of the floor 150 .

[0078] The connection surface 1148 of the bottom side beam 114 is lower than the top surface 1146 of the bottom side beam 114, and is located outside the top surface 1146 of the bottom side beam 114, and is used to connect with the facade structure of the exchange box through fasteners or glue. Specifically, the connection surface 1148 of the bottom side beam 114 is used to connect with the bottom side beam 600, so that the side wall 300 is installed on the bottom frame 100 when the exchange box is assembled.

[0079] The top surfaces of the front beam 112, the rear beam 113 and the bottom side beam 114 are not higher than the upper surface of the floor, and the chassis as a whole has a smaller height, which can better utilize the upper space of the chassis during shipment, thereby improving shipment efficiency.

[0080] See also Figures 7 to 9 The corner piece 120 is fixedly arranged at the bottom of the base frame 100 and extends outwardly beyond the outer side surface of the bottom side beam 114 .

The corner piece body 121 is welded to the bottom cross beam 115 and the bottom side beam 114, and partially extends beyond the outer side of the bottom side beam 114. The specific structure of the corner piece 120 can refer to the corner piece structure in the related art.

[0082] The first reinforcement member 130 is fixed to the bottom side beam 114 in alignment with the corner piece 120 and extends outwardly beyond the connecting surface 1148 of the bottom side beam 114 . The bottom surface of the first reinforcement member 130 is connected to the upper surface of the corner piece 120 .

[0083] See also Fig.11 and Fig.12 In this embodiment, the cross section of the first reinforcement member 130 is in an "L" shape. The first reinforcement member 130 includes a first horizontal plate 131 arranged horizontally, and a first vertical plate 132 bent upward and extended from the outer side of the first horizontal plate 131. The inner side of the first horizontal plate 131 is fixed to the bottom of the bottom edge beam 114, and the outer side thereof extends outwardly beyond the connecting surface 1148 of the bottom edge beam 114, so that there is a gap between the first vertical plate 132 and the connecting surface 1148 of the bottom edge beam 114, and the bottom surface of the first horizontal plate 131 is connected to the upper surface of the corner piece 120.

[0084] The first reinforcing member 130 is provided with a first connection hole 133 for connecting to the vertical structure of the exchange box. In this embodiment, the first connection hole 133 is provided on the first vertical plate 132 for connecting to the bottom side beam 600 .

[0088] In this embodiment, the buckling portion 630 includes a horizontal buckling horizontal plate 631, a buckling vertical plate 632 bent downwardly and extended from the inner side of the buckling horizontal plate 631, and a buckling horizontal plate 633 extending inwardly from the lower end of the buckling vertical plate 632. When the bottom side beam body 610 is connected to the bottom frame body 110, the buckling vertical plate 632 is attached to the connecting surface 1148 of the bottom side beam 114, and the buckling horizontal plate 633 is attached to the bottom surface of the bottom side beam 114.

[0089] Furthermore, the mounting hole 109 on the base frame body 110 is aligned with the buckled vertical plate 632, and a mounting hole 609 is opened in alignment, so that the buckled portion 630 and the bottom side beam 114 can be attached to each other and connected by fasteners, thereby fixing the bottom side beam 600 on the base frame 100.

[0090] The buckle part 630 is provided with a clearance opening 634 for the first reinforcement member 130. In this embodiment, the clearance opening 634 is provided on the buckle vertical plate 632 and the buckle horizontal plate 633. When the buckle part 630 is assembled to the base frame body 110, the clearance opening 634 is used for the first reinforcement member 130 to pass through the buckle part 630 to avoid interference with the first reinforcement member 130.

[0091] The second reinforcement member 620 is disposed in alignment with the first reinforcement member 130 , and the second reinforcement member 620 is connected to the outer side of the avoidance opening 634 .

[0092] See also Figures 7 to 15 The second reinforcement 620 includes a vertical second vertical plate 621 and a second horizontal plate 622 extending inward from the lower end of the second vertical plate 621; the upper end of the second vertical plate 621 is connected to the snap-fit ​​horizontal plate 631, and there is a gap between the second vertical plate 632, and the second horizontal plate 622 is connected to the snap-fit ​​vertical plate 632 or the snap-fit ​​horizontal plate 633.

[0093] A second connection hole 623 is formed on the second reinforcement member 620 in alignment with the first connection hole 133 . In this embodiment, the second connection hole 623 is formed on the second vertical plate 621 , and the bottom side beam body 610 can be connected and fixed to the connection surface of the bottom frame 100 .

[0094] In this embodiment, when assembling the bottom side beam body 610 and the bottom frame body 110, the first reinforcement 130 passes through the avoidance opening 634 and is fitted and connected to the second reinforcement 620, and the first connecting hole 133 and the second connecting hole 623 are made opposite to each other, so that the first reinforcement 130 and the second reinforcement 620 can be connected and fixed by fasteners that pass through the first connecting hole 133 and the second connecting hole 623.

[0095] Furthermore, a snap-fit ​​hole 624 is provided on the second horizontal plate 622, so that when the bottom side beam body 610 is connected to the base frame body 110, the snap-fit ​​hole 624 is snap-fitted to the periphery of the corner piece 120 to limit the horizontal torsion of the corner piece 120, thereby protecting the base frame body 110 from the torsion of the corner piece 120.

[0096] See also Fig.16 and Fig.17 A reinforcing plate 625 is also provided between the inner side of the second vertical plate 621 and the buckled vertical plate 632. The reinforcing plate 625 is horizontally arranged so that when the bottom side beam body 610 is connected to the bottom frame body 110, the reinforcing plate 625 can abut against the top of the first vertical plate 132. The reinforcing plate 625 strengthens the connection strength between the second vertical plate 621 and the bottom side beam body 610. When the bottom side beam body 610 is assembled and connected to the bottom frame body 110, the reinforcing plate 625 can abut against the top of the first vertical plate 132, defining the relative height position of the bottom side beam body 610 and the bottom frame body 110, so that the mounting holes (109, 609) of the bottom side beam body 610 and the bottom frame body 110 correspond to each other, and the first connection hole 133 corresponds to the second connection hole 623, so as to facilitate the installation of the fastener.

[0097] Furthermore, the second reinforcement 620 is closed at both ends along the length direction of the base frame body 110. In this embodiment, the second reinforcement 620 also includes two sealing plates 626, and the two sealing plates 626 are arranged at both ends in the length direction of the second vertical plate 621. The sealing plates 626 are vertically arranged and connected to the second vertical plate 621, the second horizontal plate 622 and the snap-fitting vertical plate 632 to increase the strength of the second reinforcement 620.

[0098] The provision of the first reinforcing member 130 increases the stress-bearing area of ​​the corner member 120 and the chassis body 110 , thereby preventing the chassis body 110 from being damaged due to excessively concentrated pressure from the corner member 120 on the chassis.

[0099] The first reinforcement member 130 and the second reinforcement member 620 are connected and fixed, so that the force on the corner member 120 can be transmitted to the second reinforcement member 620 through the first reinforcement member 130, so as to avoid excessive concentration of pressure from the corner member 120 on the chassis body 110. By fixing the first reinforcement member 130 and the second reinforcement member 620 by fasteners, the chassis body 110 and the bottom side beam body 610 do not need to be welded after being connected, which reduces the workload of rework and effectively protects the coating on the surface of the chassis structure.

[0100] See also Figures 7 to 17 The base frame 100 and the bottom side beam 600 of this embodiment are transported in the form of loose parts and assembled at a different location. When assembling the base frame 100 and the bottom side beam 600, the bottom side beam body 610 approaches from the outside of the base frame body 110 and fits on the outer side surface of the base frame body 110. When the bottom side beam body 610 and the base frame body 110 fit together, the buckling vertical plate 632 of the buckling part 630 fits on the outer side surface of the base frame body 110, the buckling horizontal plate 633 fits on the bottom of the base frame body 110, and the fasteners pass through the buckling vertical plate 632 and the mounting holes (109, 609) on the base frame body 110 to fix the base frame 100 and the bottom side beam 600.

[0101] When the bottom side beam 600 and the bottom frame 100 are fitted together, the first reinforcement 130 passes through the avoidance opening 634 on the buckle 630, so that the outer side surface of the first vertical plate 132 of the first reinforcement 130 is fitted to the second vertical plate 621 of the second reinforcement 620, the bottom surface of the first horizontal plate 131 is fitted to the second horizontal plate 622, and the engaging hole 624 on the second horizontal plate 622 is engaged with the outer periphery of the corner piece 120. The fastener passes through the first connection hole 133 on the first reinforcement 130 and the second connection hole 623 of the second reinforcement 620 to connect and fix the first reinforcement 130 and the second reinforcement 620. The connection between the first reinforcement 130 and the second reinforcement 620 does not need to be connected by welding, which avoids the damage of the surface coating of the bottom frame structure by the welding operation.

[0102] When the first reinforcement 130 is attached to the second reinforcement 620, the top end of the first vertical plate 132 abuts against the reinforcement plate 625 to position the first reinforcement 130 and the second reinforcement 620 in height, so that the first connecting hole 133 on the first reinforcement 130 and the second connecting hole 623 on the second reinforcement 620 are relatively positioned in height, and the mounting holes (109, 609) on the first reinforcement 130 and the second reinforcement 620 are relatively positioned in height to facilitate the passage of fasteners.

[0103] The two bottom side beams 600 are arranged corresponding to the two side walls 300 , and the two side walls 300 can be respectively connected to the top of the two bottom side beams 600 and fixed by fasteners and / or glue.

[0104] See also Fig.18 The bottom side beam 600 is connected to the lower part of the side wall 300. The bottom side beam 600 includes a side beam inner panel 640 and a side beam outer panel 650 located outside the side beam inner panel 640. The side beam inner panel 640 and the side beam outer panel 650 are connected together.

[0105] See also Fig.19 and Fig. 20 The bottom side beam 600 protrudes upward to form a vertical connecting plate 653. Specifically, the side beam outer panel 650 includes a vertical side beam outer panel 651, a receiving plate 652 bent inwardly from the upper end of the side beam outer panel 651, and a connecting plate 653 bent upwardly from the inner end of the receiving plate 652.

[0106] See again Fig. 20 A plurality of through long holes 654 are provided on the connecting plate 653 along the length direction of the exchange box, and the length direction of the long holes 654 is parallel to the length direction of the exchange box.

[0107] In this embodiment, the long hole 654 is a waist-shaped hole, and the long hole 654 passes through the two side surfaces of the connecting plate 653 along the width direction of the exchange box.

[0108] See again Fig.19 The side beam inner plate 640 includes a side beam inner plate 641 and a bearing plate 642 that is bent and extended outward from the upper end of the side beam inner plate 641 . The side beam inner plate 641 and the side beam outer plate 651 are arranged at intervals, and the bearing plate 642 is connected to the lower surface of the receiving plate 652 .

[0109] It can be understood that the bottom side beam 600 can be an integral plate-shaped structure and a connecting plate 653 vertically arranged thereon.

[0110] See again Figure 2 and Figure 3A protrusion 661 is provided on the receiving plate 652 to support the side wall 300 when the bottom side beam 600 and the side wall 300 are connected, so as to limit the relative height position of the bottom side beam 600 and the side wall 300 in the horizontal direction.

[0111] Through holes (not shown) are formed on the bearing plate 642 and the receiving plate 652, and connecting members 660 are inserted into the through holes. The bearing plate 642 and the receiving plate 652 are connected together by the connecting member 660, and the upper end of the connecting member 660 exceeds the receiving plate 652 to form a protrusion 661.

[0112] In this embodiment, the connecting member 660 is a rivet, and the rivet head of the rivet is located above the receiving plate 652 to form a protrusion 661. A plurality of connecting members 660 are arranged on the bottom side beam 600 along the length direction of the exchange box.

[0113] It is understandable that the connecting member 660 may also be a bolt, and a portion of the bolt extends above the receiving plate 652 to form a protrusion 661 .

[0114] See also Fig.21 The side wall 300 includes a side wall inner panel 310 and a side wall outer panel 320 , and the outer side surface of the side wall inner panel 310 and the inner side surface of the side wall outer panel 320 are bonded together, so that the side wall inner panel 310 and the side wall outer panel 320 are connected together.

[0115] See also Fig.21 and Fig. 22 The bottom surface of the side wall 300 is formed with a receiving groove 330, and the bottom of the side wall 300 is provided with a plurality of circular holes 340 along the length direction of the exchange box, and the circular holes 340 are arranged in alignment with the receiving groove 330. The axis of the circular hole 340 is parallel to the width direction of the exchange box, and the axis of the circular hole 340 passes through the receiving groove 330.

[0116] In this embodiment, the accommodating groove 330 is opened corresponding to the connecting plate 653, so that the accommodating groove 330 can engage the connecting plate 653 of the bottom side beam 600 therein, and make the circular hole 340 and the long hole 654 opposite to each other, so that the bottom side beam 600 and the side wall 300 can be connected and fixed by fasteners that pass through the circular hole 340 and the long hole 654.

[0117] The accommodating groove 330 can engage the connecting plate 653 of the bottom side beam 600 therein, so that when the bottom side beam 600 and the side wall 300 are assembled, the vertical movement toward each other and the relative movement along the width direction of the exchange box are limited, and the relative position of the bottom side beam 600 and the side wall 300 is limited, so as to facilitate the connection and fixation between the bottom side beam 600 and the side wall 300.

[0118] The connecting plate 653 is engaged in the receiving groove 330, which can effectively prevent rainwater from entering the exchange box from the outside.

[0119] When the round hole 340 and the long hole 654 are aligned and matched, a certain error in accuracy and size is allowed between the round hole 340 and the long hole 654, so that during production and processing, the round hole 340 and the long hole 654 can be first processed in the side wall 300 and the bottom side beam 600 by mechanical processing to improve production efficiency.

[0120] In the side wall 300 and the bottom side beam 600, since the round hole 340 and the long hole 654 are matched, a certain size and precision error is allowed, which can reduce the calibration or drilling work, thereby reducing the assembly time and cost.

[0121] During assembly, the connecting plate 653 is engaged in the receiving groove 330 , and the protrusion 661 supports the side wall 300 , limiting the circular hole 340 and the long hole 654 to be at the same height, so that the fasteners can be directly inserted into the circular hole 340 and the long hole 654 .

[0122] Furthermore, the accommodating groove 330 passes through both ends of the side wall 300 along the length direction of the exchange box. When the connecting plate 653 is inserted into the accommodating groove 330, it can slide in the accommodating groove 330, so that when the side wall 300 and the bottom side beam 600 are assembled, a part of the connecting plate 653 can be inserted into the accommodating groove 330 first. During the insertion process, precise positioning is not required. After insertion, the connecting plate 653 is slid in the accommodating groove 330 to align the round hole 340 with the long hole 654.

[0123] Furthermore, the protrusion 661 abuts against the lower surface of the side wall 300 , so that a gap is provided between the lower surface of the side wall 300 and the upper surface of the receiving plate 652 for setting the adhesive layer 390 .

[0124] When assembling the side wall 300 and the bottom side beam 600, the upper end of the protrusion 661 abuts against the lower surface of the side wall outer panel 320, and the gap between the lower surface of the side wall outer panel 320 and the receiving plate 652 is filled with structural adhesive to form an adhesive layer 390. The adhesive layer 390 serves to limit the relative movement of the side wall 300 and the bottom side beam 600 along the length direction of the long hole 654. At the same time, the height of the protrusion 661 can also protect the thickness of the adhesive layer 390, and prevent the adhesive layer 390 from being damaged by the extrusion force between the side wall 300 and the bottom side beam 600.

[0125] See also Figures 18 to 23In this embodiment, for the convenience of transportation, the side wall 300 and the bottom side beam 600 are transported in the form of loose parts. Before use, the side wall 300 and the bottom side beam 600 are assembled into one body. During assembly, the connecting plate 653 is inserted into the receiving groove 330, and after the long hole 654 on the connecting plate 653 and the round hole 340 on the side wall 300 are aligned, a fastener is passed through the round hole 340 and the long hole 654, and the fastener is fixed to connect and fix the side wall 300 and the bottom side beam 600.

[0126] When the connecting plate 653 is inserted into the receiving groove 330, the protrusion 661 abuts against the lower surface of the side wall 300 to limit the circular hole 340 and the long hole 654 to be at the same height. After the fastener passes through the circular hole 340 and the long hole 654 to fix the side wall 300 and the bottom side beam 600, the structural adhesive is filled between the lower surface of the side wall 300 and the upper surface of the receiving plate 652 to form an adhesive layer 390.

[0127] See again Figure 1 The connection surface 1128 of the bottom front beam 700 and the front end beam 112 is connected and fixed by fasteners and / or glue. The connection structure between the bottom front beam 700 and the front end beam 112 refers to the connection structure between the bottom side beam 114 and the bottom side beam 600.

[0128] The bottom front beam 700 is connected and fixed to the front wall 200 by fasteners and / or glue. In this embodiment, after the bottom front beam 700 and the facade structure of the front wall 200 are attached, the bottom front beam 700 and the front wall 200 are connected and fixed by rivets.

[0129] The rear sides of the bottom front beam 700 and the front end beam 112 can be connected to the bottom side beam 600 and the side wall 300 by fasteners and / or glue.

[0130] See also Figure 1 and Fig.24 The rear door 500 includes two rear door panels 510 and two rear door pillars 520 transported in the form of loose parts. The two rear door pillars 520 are symmetrically arranged, and the bottom ends of the rear door pillars 520 are fixed to the connecting surfaces 1138 at both ends of the rear end beam 113. The two rear door panels 510 are arranged side by side, and the two rear door pillars 520 constitute the frame of the rear door 500. After assembly, the two rear door panels 510 are respectively hinged to one rear door pillar 520, so that the two rear door panels 510 can be relatively opened or closed.

[0131] See also Fig.24 and Fig.25 The front side of the rear door pillar 520 can be connected to the bottom side beam 600 and the side wall 300 by fasteners and / or glue.

[0132] See again Figure 1 and Fig.24, both sides of the top plate 400 can be connected and fixed to the upper ends of the side walls 300 by fasteners and / or glue. In this embodiment, both sides of the bottom surface of the top plate 400 are aligned with the two side walls 300 and protrude downward to form top side beams 410, and the top side beams 410 can be connected to the top ends of the side walls 300 by fasteners and / or glue.

[0133] Furthermore, the top plate 400 can also be connected to the front wall 200 and the two rear door columns 520 by fasteners and / or glue to form a complete exchange box.

[0134] The base frame 100, front wall 200, two side walls 300, top plate 400, two rear door panels 510, two rear door columns 520, bottom side beams 600 and bottom front beam 700 of the exchange box of this embodiment are all loose parts for easy transportation.

[0135] Most of the fasteners in this embodiment are rivets, and a few are bolts.

[0136] This embodiment also provides a method for shipping a switching box:

[0137] See also Figure 26 to Figure 28 , multiple sets of exchange boxes are simultaneously loaded in the form of loose parts in a container for transportation. When packing, the bottom frame 100 and the top plate 400 of each set of exchange boxes are placed in the container in a buckled manner. When the bottom frame 100 and the top plate 400 are buckled, the top side beam 410 is supported in the interval between the first reinforcement 130 and the bottom side beam 114. After the bottom frame 100 and the top plate 400 of the exchange box are buckled, they are placed upright in the container along the width direction of the bottom frame 100 and the top plate 400. Among them, when the bottom frame 100 and the top plate 400 are buckled and packed, the length direction of the bottom frame 100 and the top plate 400 are placed in the container parallel to the length direction of the container.

[0138] After the bottom frames 100 and top plates 400 of multiple sets of exchange boxes are buckled together, they are placed side by side along the width direction of the container.

[0139] The bottom side beams 600 of the plurality of exchange boxes are placed side by side in the width direction of the container and are stacked in the height direction.

[0140] The two side walls 300 are placed in the gap between the bottom frame 100 and the top plate 400 so that the side walls 300 can be locked and fixed during shipment.

[0141] The other components of the exchange box (front wall 200, rear door 500, bottom side beam 600 and bottom front beam 700) are placed in the remaining length space of the container. In this embodiment, a single container can hold six sets of exchange boxes in the form of loose parts.

[0142] The heights of the top surfaces of the front end beam 112, the rear end beam and the bottom side beam are not higher than the upper surface of the floor 150. The base frame 100 as a whole has a relatively small height. The two side walls 300 are placed in the gap between the base frame 100 and the top plate 400. The upper space of the base frame 100 can be better utilized during shipment. By snapping together the base frame 100 and the top plate 400 and stacking the bottom side beams 600 side by side, the shipping volume of the exchange box is reduced, the shipping efficiency is improved, and thus the transportation cost can be reduced.

[0143] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
