[0072] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0073] Figures 1 to 6 A container according to the present invention is shown, the container comprises a first corner post 100, the first corner post 100 comprises an outer corner post 101 and an inner corner post 102, the outer corner post 101 comprises a first connecting plate 103 and a first bent plate 104 connected to the end of the first connecting plate 103. The inner corner post 102 comprises a load-bearing plate 106 and two second connecting plates 105 connected to both ends of the load-bearing plate 106, the two second connecting plates 105 are located on the same side of the load-bearing plate 106, so that the cross section of the inner corner post 102 perpendicular to the height direction D1 of the container is U-shaped, one end of the second connecting plate 105 away from the load-bearing plate 106 is connected to the first connecting plate 103, and the inner corner post 102 and the outer corner post 101 are integrally formed.

[0074] The thickness of at least a portion of the first bending plate 104 is smaller than the thickness of the first connecting plate 103 . The thickness of at least a portion of the second connecting plate 105 is smaller than the thickness of the carrying plate 106 .

[0075] According to the container of the utility model, the outer corner post 101 and the inner corner post 102 of the first corner post 100 are integrally formed, have high hardness, good wear resistance, and are not prone to cracks. The inner corner post 102 is U-shaped and buckled to the outer corner post 101, which has high structural strength and can be sealed with the door 120 to improve the sealing and waterproof performance of the container. In addition, the thickness of the non-load-bearing part of the first corner post 100 is reduced, which is conducive to reducing the weight of the container and reducing the manufacturing cost of the container.

[0076] The first corner post 100 of the container according to the present invention is described in detail below in combination with a plurality of embodiments.

[0077] First embodiment

[0078] Reference Figure 1 and Figure 2 The load-bearing plate 106 is spaced a predetermined distance from the first connecting plate 103 to enclose a cavity between the inner corner column 102 and the first connecting plate 103, so that a closed cavity structure is formed between the inner corner column 102 and the outer corner column 101, which has high structural strength, good stability, and good load-bearing performance along the height direction D1 of the container.

[0079] Reference Figure 2 In this embodiment, the thickness of the second connecting plate 105 is increased along the direction from the first connecting plate 103 to the load-bearing plate 106 (i.e., the width direction D3 of the container), so that the first corner column 100 has sufficient thickness at the load-bearing part (i.e., the part of the second connecting plate 105 close to the load-bearing plate 106 is not the smallest thinning part), thereby ensuring the load-bearing performance of the first corner column 100.

[0080] According to actual conditions, the thickness of the portion of the second connecting plate 105 close to the supporting plate 106 can be selected to be greater than or equal to the thickness of the supporting plate 106, so that the thickness of the second connecting plate 105 is partially smaller than the thickness of the supporting plate 106; it can also be selected to be smaller than the thickness of the supporting plate 106, so that the entire thickness of the second connecting plate 105 is smaller than the thickness of the supporting plate 106.

[0081] Further, see Figure 6 The container further comprises a door 120 and a seal 110. The door 120 is hinged to the outer corner post 101. The seal 110 is arranged between the door 120 and the inner corner post 102 in a closed state. Due to the inward buckling design of the inner corner post 102 and the outer corner post 101, the bearing plate 106 in the inner corner post 102 can provide a support point for the connection of the seal 110, so that when the door 120 is in a closed state, the seal 110 can be pressed tightly between the inner corner post 102 and the door 120, thereby improving the waterproof sealing performance of the container.

[0082] Reference Figure 6The container further comprises a corner piece 130 connected to the end of the first corner post 100 to serve as a corner connection piece of the bottom frame and the top frame of the container.

[0083] Second embodiment

[0084] Reference Figure 3 , which is different from the first embodiment, along the extension direction of the first connecting plate 103 (in this embodiment, the length direction D2 of the container), the first connecting plate 103 includes a first portion 207 and a second portion 208 that are spaced apart, and two second connecting plates 105 are respectively connected to opposite ends of the first portion 207 and the second portion 208, so that the inner corner post 102 and the first connecting plate 103 are configured to form a first groove 209, thereby facilitating the outer corner post 101 and the inner corner post 102 to be manufactured by an integral roll forming method while ensuring that the first corner post 100 has sufficient structural strength, thereby reducing the manufacturing difficulty compared to the first corner post 100 according to the first embodiment.

[0085] In addition, in this embodiment, the thickness of the second connecting plate 105 remains unchanged, so as to further reduce the difficulty of manufacturing the first corner column 100 .

[0086] Third embodiment

[0087] Reference Figure 4 Compared with the first corner post 100 of the second embodiment, the first corner post 100 according to the third embodiment is different in that the inner corner post 102 is formed with a second groove 308 .

[0088] In detail, the bearing plate 106 is provided with a second groove 308 with a notch facing away from the first connecting plate 103. Along the height direction D1 of the container, the extension length of the second groove 308 is the same as the extension length of the bearing plate 106, so that the structural strength of the bearing plate 106 is improved, and the structural strength of the first corner post 100 is further improved (relative to the first corner post 100 of the second embodiment).

[0089] Fourth embodiment

[0090] Reference Figure 5 Compared with the first corner column 100 of the second embodiment, the first corner column 100 according to the fourth embodiment is different in that a reinforcing rib 409 is formed in the first groove 209 .

[0091] In detail, the first corner post 100 further includes at least one reinforcing rib 409, which is connected to the bearing plate 106 and is located in the first groove 209. The provision of the reinforcing rib 409 improves the structural strength of the bearing plate 106, thereby further improving the structural strength of the first corner post 100 (relative to the first corner post 100 of the second embodiment).

[0092] In the above embodiments, for the outer corner column 101, since the first bent plate 104 is mainly used to connect the side plate 180 (described in detail later) of the container, it does not need to bear a large load compared to the first connecting plate 103, so the design that at least part of the first bent plate 104 has a thickness less than the thickness of the first connecting plate 103 can reduce the weight of the outer corner column 101 and even the first corner column 100, and reduce the manufacturing cost of the container. Optionally, the thickness of the first bent plate 104 can be entirely less than the thickness of the first connecting plate 103, or the first bent plate 104 can be designed in a gradually expanding (or contracting) form, so that the thickness of the first bent plate 104 is only partially less than the thickness of the first connecting plate 103.

[0093] Similarly, the second connecting plate 105 is mainly used for connecting the inner corner post 102 and the outer corner post 101, and does not need to bear a large load compared to the bearing plate 106. Therefore, the thickness of at least part of the second connecting plate 105 is smaller than the thickness of the bearing plate 106, which can reduce the weight of the inner corner post 102 and even the first corner post 100, and reduce the manufacturing cost of the container.

[0094] For other structures of the container, refer to Figure 7 The container further includes a gooseneck trough 140, which includes a top panel 141 and a side bending plate 142, which is connected to the top panel 141 and is located at the side of the top panel 141. The thickness of the side bending plate 142 is less than that of the top panel 141, thereby reducing the weight of the gooseneck trough 140.

[0095] Optionally, the gooseneck trough 140 can reduce the thickness of the side bending plate 142 of the gooseneck trough 140 while ensuring the structural strength of the gooseneck trough 140 through precise control of the hot rolling process, thereby reducing the weight of the gooseneck trough 140 and even the container.

[0096] Specifically, the hot rolling process is used to perform high temperature rolling to cause the side bending plate 142 of the gooseneck trough 140 to undergo plastic deformation, thereby achieving the purpose of thinning. At the same time, by optimizing the rolling parameters and the mold design, it can be ensured that the gooseneck trough 140 after thinning still has good structural strength and stability.

[0097] Further, combined with Figure 8 As shown, the container also includes a gooseneck trough back beam 150 and a bottom longitudinal beam. The gooseneck trough back beam 150 extends along the width direction D3 of the container. The first end of the gooseneck trough back beam 150 is connected to the bottom longitudinal beam, and the second end of the gooseneck trough 140 is connected to the gooseneck trough 140, so that the side of the gooseneck trough 140 is connected to the bottom longitudinal beam.

[0098] Reference Figure 8The gooseneck trough back beam 150 includes a first upper plate 151, a first side wall plate 152 and a first lower plate 153. The first upper plate 151 and the first lower plate 153 are perpendicular to the height direction D1, and the first side wall plate 152 is parallel to the height direction D1. The first side wall plate 152 connects the first upper plate 151 and the first lower plate 153 respectively, so that the cross-section of the gooseneck trough back beam 150 is U-shaped, with high structural strength, and can stably connect the gooseneck trough 140 and the bottom longitudinal beam.

[0099] Reference Fig. 9 The thickness of the first upper plate 151 and the thickness of the first lower plate 153 are both smaller than the thickness of the first side wall plate 152. Since the gooseneck trough back beam 150 is mainly connected to the gooseneck trough 140 and the bottom longitudinal beam through the first side wall plate 152, thinning the thickness of the first upper plate 151 and the first lower plate 153 can significantly reduce the weight of the container and improve the transportation efficiency of the container.

[0100] Optionally, the metal blank can be heated and rolled using a hot rolling process to obtain a gooseneck groove back beam 150 of a desired shape and size. During the hot rolling process, the plasticity and deformability of the material can be ensured by adjusting the rolling process and equipment parameters, while also reducing energy consumption and production costs.

[0101] Optionally, the hot-rolled gooseneck trough back beam 150 material may be cut and pre-processed to form a gooseneck trough back beam 150 having a thinned first upper plate 151 and a second upper plate 161 .

[0102] Alternatively, the thickness of the first upper plate 151 and the second upper plate 161 may be 70% to 85% of the thickness of the first side wall plate 152 , which is specifically selected according to the actual manufacturing requirements of the container.

[0103] Further, combined with Fig.10 and Fig.11 As shown, the container further includes a gooseneck trough longitudinal beam 160, which extends along the width direction D3 of the container and is connected to the bottom longitudinal beam, and the gooseneck trough longitudinal beam 160 is connected to the end of the gooseneck trough 140, so that the end of the gooseneck trough 140 is fixedly connected to the bottom longitudinal beam. In addition, similar to the bottom cross beam 190 of the container, the top surface of the gooseneck trough longitudinal beam 160 is also used to support the floor, and the bottom surface of the gooseneck trough 140 is also used to support the container.

[0104] Specifically, the gooseneck trough longitudinal beam 160 includes a second upper plate 161, two second side wall plates 162 and a second lower plate 163. The second upper plate 161 and the second lower plate 163 are perpendicular to the height direction D1, and the second side wall plate 162 is parallel to the height direction D1. The second side wall plate 162 connects the second upper plate 161 and the second lower plate 163 respectively, so that the cross-section of the gooseneck trough longitudinal beam 160 is rectangular and has good structural strength.

[0105] Furthermore, the thickness of the second side wall plate 162 is smaller than the thickness of the second upper plate 161 and the thickness of the second lower plate 163. Since the second side wall plate 162 is mainly used to connect the second upper plate 161 and the second lower plate 163 and does not need to bear a large load, thinning the second side wall plate 162 can effectively reduce the weight of the container, while reducing material waste and reducing the manufacturing cost of the container.

[0106] Optionally, the gooseneck trough longitudinal beam 160 is manufactured using an advanced hot rolling process. By controlling parameters such as temperature, pressure and speed during the hot rolling process, the structural strength and stability of the gooseneck main beam after the side wall is thinned can be ensured, thereby improving the overall performance and safety of the container.

[0107] Optionally, refer to Fig.12 and Fig.13 The container further includes a second corner post 170 and a side plate 180. The second corner post 170 includes a third connecting plate 171 and a second bending plate 172. The second bending plate 172 is connected to the third connecting plate 171. The end of the third connecting plate 171 is connected to the corner fitting 130 along the height direction D1 of the container, and the second bending plate 172 is connected to the side plate 180, so that the second corner post 170 and the corner fitting 130 constitute the corner of the container.

[0108] Furthermore, the thickness of the second bent plate 172 is less than that of the third connecting plate 171. Since the second bent plate 172 is mainly used to connect the side plate 180, and the load of the second corner column 170 is mainly concentrated on the portion connected to the corner piece 130, the thinning design of the second bent plate 172 can effectively reduce the weight of the second corner column 170 and even the container while ensuring the structural strength of the second corner column 170, thereby improving the transportation efficiency of the container and reducing the manufacturing cost of the container.

[0109] Optionally, the second bent plate 172 of the second corner column 170 is thinned by a hot rolling process, which effectively reduces material usage and reduces manufacturing costs.

[0110] Optionally, refer to Fig.13 and Fig.14 The side plate 180 includes a protruding plate 181, a concave plate 182 and a fourth connecting plate 183. The protruding plate 181 and the concave plate 182 are spaced apart along the inner and outer directions of the container. The fourth connecting plate 183 is arranged between the protruding plate 181 and the concave plate 182, so that the side plate 180 is a corrugated plate as a whole, has high structural strength, and is easy to process and manufacture.

[0111] Furthermore, the thickness of the fourth connecting plate 183 is smaller than the thickness of the protruding plate 181 and the thickness of the inner recessed plate 182. Since the load of the side plate 180 is mainly concentrated on the protruding plate 181 and the inner recessed plate 182, rather than the fourth connecting plate 183, the thinning treatment of the fourth connecting plate 183 can effectively reduce the weight of the side plate 180 and even the container while ensuring the structural strength of the side plate 180, thereby improving the transportation efficiency of the container and reducing the manufacturing cost of the container.

[0112] Optionally, the fourth connecting plate 183 of the side plate 180 is thinned by using a hot rolling process. Through precise control of the hot rolling process, the thickness and weight of the fourth connecting plate 183 can be effectively reduced while ensuring the structural strength of the side plate 180 .

[0113] Specifically, the hot rolling process is used to perform high temperature rolling to cause plastic deformation of the fourth connecting plate 183 of the side plate 180, thereby achieving the purpose of thinning. At the same time, by optimizing the rolling parameters and the mold design, it can also be ensured that the thinned side plate 180 still has good structural strength and stability.

[0114] In detail, the side panel 180 includes an end panel and a side panel, the end panel is perpendicular to the length direction D2 of the container, and the end panel can be arranged at one end of the container where the second corner column 170 is arranged, the side edge of the end panel is connected to the second corner columns 170 on both sides, and the top edge and bottom edge of the end panel are respectively connected to the top cross beam and the bottom cross beam 190 (described in detail later) of the container. It can be understood that the container has a door 120 at one end having the first corner column 100, and the first corner column 100 is connected to the door 120.

[0115] The side panel is parallel to the length direction D2 of the container, and both sides of the side panel are connected to the first corner post 100 and the second corner post 170 respectively, while the top side of the side panel is connected to the top longitudinal beam of the container, and the bottom side of the side panel is connected to the bottom longitudinal beam.

[0116] Optionally, refer to Fig.15 The bottom cross beam 190 of the container extends along the width direction D3 of the container, and the bottom cross beam 190 includes a third upper plate 191, a third side wall plate 192, and a third lower plate 193. The third upper plate 191 and the third lower plate 193 are perpendicular to the height direction D1, the third side wall plate 192 is parallel to the height direction D1, and the third side wall plate 192 connects the third upper plate 191 and the third lower plate 193 respectively, so that the cross section of the bottom cross beam 190 is U-shaped, which has good structural strength.

[0117] Furthermore, the thickness of the third side wall plate 192 is smaller than the thickness of the third upper plate 191 and the thickness of the third lower plate 193. Since the third side wall plate 192 does not need to bear the floor of the container or support the container, the thinning treatment of the third side wall plate 192 can effectively reduce the weight of the bottom beam 190 and even the container while ensuring the structural strength of the bottom beam 190, thereby improving the transportation efficiency of the container and reducing the manufacturing cost of the container.

[0118] Optionally, the bottom cross beam 190 thinned by the third side wall plate 192 is formed in one step by hot rolling process, so as to optimize the manufacturing process, improve the strength and stability of the bottom cross beam 190, reduce the manufacturing cost of the container and improve the production efficiency.

[0119] Specifically, the hot rolling process includes: feeding the metal raw material into a heating furnace and heating it to a suitable temperature range so that it can achieve sufficient plasticity and ductility, and then rolling the heated metal raw material through a rolling mill. The rollers on the rolling mill compress the raw material to deform it into the overall structure of the container components, and then by adjusting parameters such as the roller pressure and rolling speed, the size and shape of the components are precisely controlled. After rolling is completed, the hot-rolled components are cooled to improve their hardness and wear resistance.
