[0037] See also Figure 1 and Figure 2 The container with the concave-convex box bottom plate structure also includes a side unit 4, two of which are symmetrically arranged and respectively connected between the two left corner posts 3 and the two right corner posts 3, and the side unit 4 includes a side frame 41 fixedly connected to the upper ends of the two corresponding corner posts 3, and the lower end of the side frame 41 is hinged with a side plate 42.

[0038] See also Figure 1 and Figure 2The container with the concave-convex box bottom plate structure also includes a bottom unit 5, which is arranged between the two end plates 2. The bottom unit 5 includes two bottom frames 51 which are symmetrically distributed and fixedly connected to the lower ends of the two corner columns 3 at corresponding positions on the left and right sides, and the upper ends of the two bottom frames 51 are jointly installed with a first concave-convex plate 53.

[0039] During specific operation, the top plate 1, two end plates 2, four corner columns 3, two side frames 41, two side plates 42, two bottom frames 51 and the first concave-convex plate 53 together constitute a container with a concave-convex box bottom plate. The first concave-convex plate 53 at the bottom of the container can cooperate with the fork teeth on the existing loading and unloading forklift, which is convenient for the forklift to directly load the goods onto the container or unload the goods from the container, effectively improving the efficiency of cargo loading and unloading, and there is no need to add a pallet at the bottom of the cargo, thereby reducing the cost required for cargo loading and unloading.

[0041] During specific operation, the reinforcing plate 54 is used to connect the two bottom frames 51 to increase the strength of the connection between the two bottom frames 51. The supporting plate 55 and the rectangular plate 56 are both used to improve the supporting capacity of the first concave-convex plate 53 and improve the supporting strength of the first concave-convex plate 53.

[0043] During specific operation, the existing hydraulic pump is installed on any one of the end plates 2 , and then four first hydraulic push rods 44 are connected to the hydraulic pump. The hydraulic push rods 44 are used to control the opening and closing of the side plates 42 .

[0044] See also Figure 1 , Figure 2 and Fig. 9The container with the concave-convex box bottom plate structure also includes a stratification unit 6, which is arranged at the upper end of the first concave-convex plate 53. The stratification unit 6 includes four slide rail columns 61 distributed in a rectangular shape and fixedly connected to the corresponding corner columns 3 respectively. The four slide rail columns 61 are slidably sleeved with a third concave-convex plate 63 and a second concave-convex plate 62 distributed up and down. The first concave-convex plate 53 is connected with a plurality of driving components 64 distributed in a rectangular shape and used to drive the third concave-convex plate 63 and the second concave-convex plate 62 to rise and fall. When the cargo loading height is high, the driving component 64 drives the third concave-convex plate 63 and the second concave-convex plate 62 to move in a fixed and synchronous manner and adjust the loading distance between the second concave-convex plate 62 and the first concave-convex plate 53, and the number of cargo loading layers is two; when the cargo loading height is low, the driving component 64 drives the third concave-convex plate 63 and the second concave-convex plate 62 to move separately and adjust the loading distance between the third concave-convex plate 63 and the second concave-convex plate 62, and the number of cargo loading layers is three.

[0045] See also Figure 6 , Figure 7 and Fig. 9 The driving component 64 includes a third hydraulic push rod 641 installed at the end position of the upper end of the first concave-convex plate 53, the moving section of the third hydraulic push rod 641 slides through the second concave-convex plate 62 and is fixedly connected to the lower end of the third concave-convex plate 63, the moving section of the third hydraulic push rod 641 is provided with a plug-in through hole near the end position, the moving section of the third hydraulic push rod 641 is slidably sleeved with a connecting sleeve 642 fixedly connected to the lower end of the second concave-convex plate 62, a clamping screw 643 is passed through the middle of the connecting sleeve 642, and the clamping screw 643 is plugged into the plug-in through hole of the moving section of the third hydraulic push rod 641.

[0046] See also Fig. 9 A plurality of evenly distributed reinforcing ribs are installed inside the corner column 3 , and the reinforcing ribs are fixedly connected to the slide rail column 61 . The plurality of reinforcing ribs are located in the lower half of the slide rail column 61 and do not exceed the shortest height of the third hydraulic push rod 641 .

[0047] During specific operation, the third hydraulic push rod 641 is connected to the existing hydraulic pump. When loading cargo, if the height of the cargo is high, the moving section of the third hydraulic push rod 641 can drive the third concave-convex plate 63 to move upward, and at the same time, the moving section of the third hydraulic push rod 641 drives the second concave-convex plate 62 to move upward through the connecting sleeve 642 and the clamping screw 643, thereby changing the spacing between the second concave-convex plate 62 and the first concave-convex plate 53 to meet the needs of cargo placement, and after the cargo is placed, the third hydraulic push rod 641 can also drive the second concave-convex plate 62 to press down on the cargo to align and tighten and limit. If the height of the cargo is short, the third concave-convex plate 63 and the second concave-convex plate 62 divide the container into two parts, upper and lower, which is convenient for placing the cargo up and down. The shortest spacing between the second concave-convex plate 62 and the first concave-convex plate 53 is consistent with the shortest distance of the third hydraulic push rod 641, and the third concave-convex plate 63 can also cooperate with the fork teeth on the forklift to facilitate loading and unloading of cargo.

[0048] After the clamping screw 643 is separated from the connecting sleeve 642 and the moving section of the third hydraulic push rod 641, the second concave-convex plate 62 slides relative to the moving section of the third hydraulic push rod 641, so that it can be separated from the third concave-convex plate 63, further increasing the number of layers inside the container, effectively improving the utilization rate of the internal space of the container, and being able to load goods of different heights, thereby improving the flexibility of container use. The four slide rail columns 61 are connected to the four corner columns 3 through multiple reinforcing ribs, and at the same time, the four slide rail columns 61 are connected to the second concave-convex plate 62 and the third concave-convex plate 63, further limiting the positions of the four corner columns 3, thereby improving the stability of the container.

[0049] See also Figure 2 and Figure 3 A plurality of evenly distributed snap-on components 43 are installed at one end of the inner end surface of the side panel 42 away from the hinge position, and the snap-on components 43 include two support seats 431 symmetrically installed on the side panel 42 and in an arc-shaped structure. A snap-on plate 432 is detachably installed on the two support seats 431, and a snap-on through hole 433 is opened in the middle of the snap-on plate 432.

[0050] During specific operation, after the cargo is loaded, the first hydraulic push rod 44 is started, and the four first hydraulic push rods 44 respectively drive the two side panels 42 on both sides to rotate downward to a vertical state. At this time, the side panels 42 cooperate with the corresponding bottom frames 51 to realize the function of closing the container. At the same time, the sealing pads laid on the side panels 42 improve the sealing performance of the container when it is closed.

[0051] See also Figure 2 , Figure 6 and Figure 8The bottom frame 51 is provided with a locking component 52 that cooperates with multiple snap components 43 at the same time. When the side panels 42 are rotated to a vertical state to close the container, the multiple locking components 52 perform synchronous limiting locking operations on the multiple snap components 43 to integrally fix the side unit 4 on the bottom unit 5; the locking component 52 includes a plurality of limiting components 521 that are evenly distributed and connected to the bottom frame 51, and a connecting rod 522 is connected between two adjacent limiting components 521. Any one of the limiting components 521 is connected to a second hydraulic push rod 523, and the second hydraulic push rod 523 is hinged to the corresponding reinforcing plate 54 on the bottom unit 5.

[0052] See also Figure 2 , Figure 6 , Figure 8 and Fig.10 The limiting assembly 521 includes a fixing plate 5211 which is installed at the upper end of the bottom frame 51 and has a connecting through hole in the middle. The fixing plate 5211 is fixedly connected to the inner end surface of the convex section corresponding to the first concave-convex plate 53 and the inner end surface of the convex section is not installed with a rectangular plate 56. A limiting frame 5212 with a U-shaped structure is installed at one end of the fixing plate 5211 close to the middle of the first concave-convex plate 53. A rotating sleeve 5213 is rotatably connected to the middle of the vertical section of the limiting frame 5212. A rectangular rod 5214 is inserted in the middle of the rotating sleeve 5213. A clamping joint 5215 is installed at one end of the rectangular rod 5214 close to the fixing plate 5211.

[0053] See also Figure 2 , Figure 6 , Figure 8 and Fig.10 The limiting assembly 521 also includes a moving rotating part driven by a second hydraulic push rod 523 to move and drive the rectangular rod 5214 to rotate under force. The moving rotating part includes a toggle rod 5216 sleeved on the end of the rectangular rod 5214 away from the fixed plate 5211. The end of the rectangular rod 5214 away from the clamping joint 5215 is integrally formed with a threaded column, and a nut for limiting the toggle rod 5216 is threadedly connected to the threaded column. A waist-shaped hole is opened near the lower end of the toggle rod 5216. A transmission screw 5217 is slidably connected in the waist-shaped hole, and a cylindrical rod 5218 is threadedly connected to the transmission screw 5217. The cylindrical rod 5218 is slidably sleeved with two guide sleeves 5219 located on both sides of the transmission screw 5217. The guide sleeves 5219 are fixedly connected to the bottom frame 51, and the cylindrical rod 5218 is fixedly connected to the connecting rod 522. The moving section end of the second hydraulic push rod 523 is fixedly connected to the corresponding cylindrical rod 5218 through a connecting screw.

[0054] During specific operation, the second hydraulic push rod 523 is connected to the existing hydraulic pump. After the container door is closed, the side plate 42 rotates to a vertical state. The side plate 42 drives the multiple snap plates 432 through the corresponding connecting holes on the fixing plate 5211 through the multiple support seats 431 and enters the limit frame 5212. At the same time, the snap joint 5215 penetrates the snapping hole 433 and moves between the two support seats 431. Then, the second hydraulic push rod 523 is started. The second hydraulic push rod 523 drives the corresponding cylindrical rod 5218 to slide in the two matching guide sleeves 5219. The multiple cylindrical rods 5218 on the same side move simultaneously through the multiple connecting rods 522. When the cylindrical rod 5218 moves, it drives the transmission screw 5217 The toggle rod 5216 moves in the waist-shaped hole, and the transmission screw 5217 pushes the toggle rod 5216. The toggle rod 5216 rotates under force and drives the rectangular rod 5214 to rotate. The rectangular rod 5214 rotates on the limit frame 5212 through the rotating sleeve 5213 and drives the clamping joint 5215 to rotate. The clamping joint 5215 rotates between the two support seats 431 until it is vertical to the clamping through hole 433. The clamping through hole 433 limits the clamping joint 5215, and the side unit 4 is integrated and fixed on the bottom unit 5, thereby improving the limiting strength of the closed side panel 42 to the cargo, further improving the closing strength of the container side panel 42, reducing labor costs, and then stopping the operation of the second hydraulic push rod 523.

[0055] When the container is transported to the destination, the second hydraulic push rod 523 is started, and the second hydraulic push rod 523 drives the corresponding cylindrical rod 5218 to reset. The cylindrical rod 5218 pushes the toggle rod 5216 through the transmission screw 5217. The toggle rod 5216 is rotated by force and drives the card joint 5215 to rotate to a state parallel to the card connection hole 433 through the rotation of the rectangular rod 5214. Then the first hydraulic push rod 44 is started, and the four first hydraulic push rods 44 respectively drive the two side plates 42 on both sides to rotate upward, so as to open the container, and then the goods in the container are unloaded by a forklift. The container with a side door can directly unload all the goods in the container by a forklift, reducing the steps of manually pushing the goods, avoiding the wear of the container bottom plate, i.e., the first concave-convex plate 53, improving the service life of the container and the efficiency of cargo loading and unloading, and reducing the cost of cargo loading and unloading.
