[0068] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0069] In this document, ordinal numbers such as “first” and “second” cited in this application are merely identifiers and do not have any other meanings, such as a specific order, etc.

[0070] To thoroughly understand the embodiments of the present application, a detailed structure will be provided in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other embodiments.

[0071] First embodiment

[0072] The present application provides a container. The container can be used to transport bulk cargo. The container has a bottom opening 111 for unloading bulk cargo.

[0073] Please refer to Figures 1 to 7 The container includes a box body 110. The box body 110 is a roughly rectangular parallelepiped structure. The top end of the box body 110 has a top opening. Bulk cargo can be loaded into the box body 110 through the top opening. The container also includes a top cover. The top cover is removably connected to the top end of the box body 110 for opening or closing the top opening. No doors are provided on the end walls and side walls of the box body 110. Reinforcement components (not shown) connecting the end walls and side walls are provided at the corners of the box body 110 to strengthen the connection strength of the end walls and side walls.

[0074] It is understood that in an embodiment not shown, the container may not be provided with a top cover. In this case, the container includes a tarpaulin. The tarpaulin is used to cover the top opening.

[0075] like Figures 1 to 5As shown, the bottom end of the box body 110 is provided with a bottom opening 111. The box body 110 also includes a bottom door 120. One end of the bottom door 120 is pivotally connected to the end portion of the bottom end of the box body 110 along the width direction of the box body 110. In this way, the bottom door 120 can rotate between an open position to open the bottom opening 111 and a closed position to close the bottom opening 111. When the bottom door 120 is in the open position, bulk cargo in the box body 110 can be unloaded through the bottom opening 111. A hook portion 121 is provided at the end portion of the bottom door 120 along the length direction of the box body 110.

[0076] It is understood that, in an embodiment not shown, the bottom door may also be pivotally connected to the bottom end of the box body at a substantially middle position along the width direction of the box body.

[0077] The container further includes a first slider 130. The first slider 130 is connected to an end of the box body 110 along the length direction of the box body 110. The first slider 130 is movably arranged along the height direction of the box body 110. In this way, the first slider 130 can move along the height direction of the box body 110 between a slide-locked position and a slide-unlocked position.

[0078] The container also includes a connecting member 164. The connecting member 164 can be a rod. The connecting member 164 is located below the first sliding member 130 and is connected to the first sliding member 130. The container also includes a connecting rod assembly 140. The connecting rod assembly 140 includes a first connecting rod 141 and a second connecting rod 142. The first connecting rod 141 and the second connecting rod 142 are both inclined in the height direction of the box body 110. The first end of the first connecting rod 141 is pivotally connected to the connecting member 164, and is further connected to the first sliding member 130 through the connecting member 164. The first end of the second connecting rod 142 is connected to the first connecting rod 141. Along the length direction of the first connecting rod 141, the second connecting rod 142 is movable relative to the first connecting rod 141 between a short connection position and a long connection position. As a result, the structure of the box body 110 is simple.

[0079] When the second connecting rod 142 is in the short connection position, the dimensions of the connecting rod assembly 140 along the length of the first connecting rod 141 are the short connection dimensions. When the second connecting rod 142 is in the long connection position, the dimensions of the connecting rod assembly 140 along the length of the first connecting rod 141 are the long connection dimensions. The short connection dimension is smaller than the long connection dimension. In other words, the first end of the second connecting rod 142 is closer to the first end of the first connecting rod 141 when the second connecting rod 142 is in the short connection position than when the second connecting rod 142 is in the long connection position. When the second connecting rod 142 is in the long connection position, the first end of the second connecting rod 142 is located at the end of the long hole 143 (described below) away from the first end of the first connecting rod 141. The second end of the second connecting rod 142 is pivotally connected to the bottom door 120 via the adjustment assembly 144 (described below).

[0080] Please continue to refer to Figures 1 to 5 The container further includes a locking hook 150. The locking hook 150 is pivotally connected to the container body 110. This allows the locking hook 150 to rotate between a hooked position and an unhooked position. When the bottom door 120 is in the closed position, the locking hook 150 in the hooked position can hook onto the hooking portion 121, thereby locking the bottom door 120 in the closed position. When the locking hook 150 is in the unhooked position, the locking hook 150 is free from the hooking portion 121, allowing the bottom door 120 to rotate.

[0081] The connecting member 164 is pivotally connected to the locking hook 150. In this way, the first sliding member 130 moving in the height direction of the box body 110 can drive the locking hook 150 to rotate via the connecting member 164. In this way, the first sliding member 130, the locking hook 150 and the connecting rod assembly 140 are linked.

[0082] Specifically, such as Figure 1 As shown, when the first sliding member 130 is in the sliding locking position, the bottom door 120 is in the closed position, the second connecting rod 142 is in the long connection position, and the lock hook 150 is in the hooking position. Figure 1 and Figure 2 As shown, if bulk cargo within the box 110 needs to be unloaded, the first sliding member 130 is moved downward from the slide-locked position to the slide-unlocked position. During the downward movement of the first sliding member 130 from the slide-locked position to the slide-unlocked position, the first sliding member 130 drives the first connecting rod 141 to move relative to the second connecting rod 142, causing the second connecting rod 142 to move toward the short connection position relative to the first connecting rod 141. During the downward movement of the first sliding member 130 from the slide-locked position to the slide-unlocked position, the first sliding member 130 drives the lock hook 150 to rotate from the hooked position to the unhooked position.

[0083] like Figure 2 and Figure 3 As shown, when the first sliding member 130 is in the slide-unlock position, the lock hook 150 is in the unhooked position, releasing the lock on the bottom door 120. When the first sliding member 130 is in the slide-unlock position, the second connecting rod 142 is in the short connection position. At this point, the bottom door 120 automatically flips downward under the influence of gravity and the cargo within the box 110, rotating from the closed position to the open position. During the flipping process of the bottom door 120, the second connecting rod 142 moves relative to the first connecting rod 141, moving from the short connection position to the long connection position.

[0084] like Figure 1 、 Figure 4 and Figure 5As shown, after the bulk cargo in the box 110 is unloaded, if the bottom door 120 is needed to close the bottom opening 111, the first sliding member 130 is moved upward from the slide unlocking position to the slide locking position. During the process of the first sliding member 130 moving upward from the slide unlocking position to the slide locking position, the first sliding member 130 drives the lock hook 150 to rotate from the unhooking position to the hooking position through the connecting member 164, and at the same time drives the bottom door 120 to rotate from the open position to the closed position through the connecting rod assembly 140. Figure 1 As shown, when the bottom door 120 rotates to the closed position, the lock hook 150 rotates to the hooking position and is hooked to the hooking portion 121 of the bottom door 120 .

[0085] In this embodiment, the first sliding member 130, the locking hook 150 and the connecting rod assembly 140 are linked together. When the first sliding member 130 moves between the sliding locking position and the sliding unlocking position, the bottom door 120 is rotated between the open position and the closed position by driving the movement of the connecting rod assembly 140 and the locking hook 150. In this way, the bottom door 120 of the container can be opened by operating the first sliding member 130. The operation of opening the bottom door 120 of the container is simple, and there is no need to flip the box body 110 by a sling to unload the bulk cargo in the box body 110. The operation of unloading the bulk cargo in the box body 110 is simple and safe.

[0086] Preferably, please refer to Figures 1 to 5 First connecting rod 141 is provided with an elongated hole 143. The long axis of elongated hole 143 is parallel to the length of first connecting rod 141. The first end of second connecting rod 142 is connected to first connecting rod 141 through elongated hole 143. Thus, the first end of second connecting rod 142 can move within elongated hole 143 along the long axis of elongated hole 143, thereby enabling second connecting rod 142 to move between a long connection position and a short connection position. As a result, the structure of connecting rod assembly 140 is simple.

[0087] It is understood that, in an embodiment not shown, the long hole may also be provided on the second connecting rod. In this case, the second end of the first connecting rod is connected to the second connecting rod through the long hole.

[0088] It is understood that in an embodiment not shown, the connecting rod assembly may also be constructed as a telescopic sleeve structure in which the first connecting rod is sleeved on the second connecting rod.

[0089] Preferably, please refer to Figures 1 to 5The lock hook 150 includes a hook body 151, a hook head 152, a first pivoting portion 153, and a second pivoting portion 154. The hook head 152, the first pivoting portion 153, and the second pivoting portion 154 are all located on the same side of the hook body 151. The hook head 152, the first pivoting portion 153, and the second pivoting portion 154 are all connected to the hook body 151. Along the height direction of the box body 110, the hook head 152, the first pivoting portion 153, and the second pivoting portion 154 are spaced apart. The first pivoting portion 153 is pivotally connected to the box body 110, the second pivoting portion 154 is connected to the first sliding member 130 via a connector 164, and the hook head 152 is used to hook to the hooking portion 121. Thus, the lock hook 150 has a simple structure.

[0090] The lower end of the hook head 152 has a hook guide slope 155. The hook guide slope 155 is inclined relative to the height direction of the hook 150. When the hook 150 is hooked to the hooking portion 121, the height direction of the hook 150 is substantially parallel to the height direction of the housing 110. As the first slider 130 moves from the slide-unlocked position to the slide-locked position, the hooking portion 121 abuts against the hook guide slope 155, sliding along the hook guide slope 155, thereby hooking the hook 150 to the hooking portion 121. This allows the hook head 152 to more conveniently hook to the hooking portion 121.

[0091] Further preferably, the locking hook 150 is configured as a substantially F-shaped structure. Thus, the structure of the locking hook 150 is simpler.

[0092] like Figures 1 to 5 As shown, the container further includes a pivot member 160. One end of the pivot member 160 is pivotally connected to the second pivot portion 154 of the locking hook 150. The other end of the pivot member 160 is pivotally connected to a connecting member 164, which in turn is connected to the first sliding member 130. As a result, the first sliding member 130 needs to move downward a greater distance to allow the locking hook 150 in the hooked position to rotate to the unhooked position. This allows the bottom door 120 to open to a greater angle.

[0093] Preferably, the pivot member 160 is an elastic member. This allows the pivot member 160 to bend and then recover after bending. For example, the pivot member 160 may be a cylindrical spring. In this way, if the hook portion 121 and the lock hook 150 interfere, preventing the bottom door from closing properly, the pivot member 160 can bend, allowing the lock hook 150 to hook onto the hook portion 121. Furthermore, the elastic configuration of the pivot member 160 allows the first sliding member 130 to continue moving downward a greater distance even when the lock hook 150 is rotated to the unhooked position. This allows the bottom door 120 to open to a wider angle.

[0094] It is understood that in an embodiment not shown, a lock hook drive assembly may also be provided to drive the rotation of the lock hook. In this case, the lock hook and the connecting rod assembly are not linked.

[0095] Preferably, if Figures 1 to 5 As shown, the container further includes a first guide rail 163. The length of the first guide rail 163 extends along the height direction of the container 110. The first guide rail 163 is connected to the container 110. The first slider 130 is connected to the first guide rail 163. The first slider 130 and the first guide rail 163 cooperate to guide the movement of the first slider 130 along the height direction of the container 110. As a result, the movement of the first slider 130 along the height direction of the container 110 is more stable.

[0096] Preferably, the container further comprises a second sliding member 190 and a second guide rail. The second sliding member 190 is located below the first sliding member 130. The second sliding member 190 is movably connected to the box body along the height direction of the box body 110. The length direction of the second guide rail extends along the height direction of the box body. The second sliding member 190 is connected to the second guide rail. The second sliding member 190 and the second guide rail cooperate to guide the movement of the second sliding member 190 along the height direction of the box body. The connecting member 164 is connected to the second sliding member 190. The second sliding member 190 is pivotally connected to the pivot member 160. In this way, when the first sliding member 130 moves along the height direction of the box body 110, the first sliding member 130 drives the locking hook 150 to rotate through the connecting member 164, the second sliding member 190 and the pivot member 160. As a result, the structure of the box body 110 is simple.

[0097] Further preferably, the cross section of the first guide rail 163 (the cross section is perpendicular to the height direction of the box body 110) is T-shaped. This facilitates the selection of the first guide rail 163. It is understood that in an embodiment not shown, the first guide rail can be a planar guide rail.

[0098] Preferably, please refer to Figures 1 to 5 The connecting rod assembly 140 further includes an adjustment assembly 144. The length of the adjustment assembly 144 is adjustable. The second end of the second connecting rod 142 is connected to one end of the adjustment assembly 144. The other end of the adjustment assembly 144 is pivotally connected to the bottom door 120. The adjustment assembly 144 can be an adjustment rod of the prior art and will not be described in detail here. Thus, the length of the adjustment assembly 144, and thus the length of the connecting rod assembly 140, can be adjusted as needed, thereby increasing the angle at which the bottom door 120 can be opened.

[0099] It is understood that in an embodiment not shown, the lengths of the first connecting rod and the second connecting rod are adjustable. In this way, the lengths of the first connecting rod and the second connecting rod can be adjusted as needed, thereby adjusting the angle at which the bottom door can be opened.

[0100] Preferably, the container further includes a buffer assembly (not shown). The buffer assembly can be a tension spring, a compression spring, or an air spring. The buffer assembly is connected to one of the bottom door 120 and the container body 110. When the bottom door 120 rotates, the buffer assembly can slow down the rotation speed of the bottom door 120.

[0101] Preferably, there are two bottom doors 120. The two bottom doors 120 form a bifold door arrangement. There are two locking hooks 150 and two connecting rod assemblies 140. The two locking hooks 150 are provided in a one-to-one correspondence with the two bottom doors 120. The two connecting rod assemblies 140 are provided in a one-to-one correspondence with the two bottom doors 120. The bottom doors 120 are connected to the corresponding connecting rod assemblies 140 and locking hooks 150.

[0102] Preferably, the first sliding member 130, the connecting member 164, the connecting rod assembly 140, the pivoting member 160, the locking hook 150, the locking member 165 and the locking member elastic member 166 do not protrude from the outer contour of the box body 110, thereby facilitating the transportation of the container.

[0103] Preferably, the container further includes a seal 168. The seal 168 may be a rubber seal. The seal 168 is connected to one of the container body 110 and the bottom door 120. When the bottom door 120 is in the closed position, the bottom door 120 presses the seal 168 against the container body 110 to seal the gap between the bottom door 120 and the container body 110.

[0104] Preferably, please refer to Figures 1 to 5 The container also includes an adjustment limit assembly 169. The adjustment limit assembly 169 is connected to the bottom frame of the box body 110. When the bottom door 120 is in the closed position, the adjustment limit assembly 169 can act on the bottom door 120 to press the bottom door 120 to the box body 110. Specifically, the adjustment limit assembly 169 includes a pressing piece and a bolt. The bolt is passed through the pressing piece. The bolt is threadedly connected to the bottom frame of the box body 110. When the bottom door 120 is in the closed position, the pressing piece can be located below the free end of the bottom door 120. At this time, tightening the bolt can cause the pressing piece to press the free end of the bottom door 120 to the bottom frame. In this way, the bottom door 120 in the closed position can be pressed against the bottom frame of the box body 110.

[0105] It will be appreciated that in an embodiment not shown, the adjustable limit assembly includes a latch. The free end of the bottom door may be provided with a first latch hole. The base frame may be provided with a second latch hole corresponding to the first latch hole. When the free end of the bottom door is pressed against the base frame, the first latch hole is located at the second latch hole. In this case, the latch may be inserted into both the first and second latch holes. In this manner, the free end of the bottom door is constantly pressed against the base frame.

[0106] Preferably, the container also includes a mopping protection portion (not shown). This mopping protection portion is disposed at the free end of the bottom door 120. When the bottom door 120 is in the open position, the mopping protection portion is located above or flush with the lower surface of the chassis. This mopping protection portion thus increases the strength of the bottom door 120 and prevents deformation. Furthermore, the mopping protection portion prevents the bottom door 120 from mopping the floor, thereby protecting the bottom door 120.

[0107] Please refer to Figures 1 to 7 This embodiment also provides a sling. The first sliding member 130 is provided with an operating portion 131 for connecting with the sling. Figure 6 and Figure 7 As shown, the spreader includes a spreader body 170. The spreader body 170 can be substantially the same as the body of an existing spreader used for lifting containers. A detailed description thereof will not be repeated here. The spreader also includes a drive assembly. The drive assembly includes a first drive assembly 171 and a second drive assembly 172.

[0108] The first drive assembly 171 can be a drive cylinder. The cylinder of the first drive assembly 171 is pivotally connected to one end of the spreader body 170 along the length of the spreader. It should be noted that when the spreader is lifting a container, the length of the spreader is parallel to the length of the container, the width of the spreader is parallel to the width of the container, and the height of the spreader is parallel to the height of the container.

[0109] The head of the first driving assembly 171 is arranged at the free end of the cylinder shaft of the first driving assembly 171. In this way, along the length direction of the first driving assembly 171, the head of the first driving assembly 171 is movably arranged.

[0110] The second drive assembly 172 may be a drive cylinder. The cylinder of the second drive assembly 172 is connected to one end of the sling body 170 along the length direction of the sling. The second drive assembly 172 is located above the sling body 170. The length direction of the second drive assembly 172 is parallel to the length direction of the sling.

[0111] It can be understood that in an embodiment not shown, the second drive assembly can also be a screw nut structure.

[0112] Please continue to refer to Figure 6 and Figure 7 The head of second drive assembly 172 is disposed at the free end of the piston shaft of second drive assembly 172. Thus, the head of second drive assembly 172 is movably disposed along the length of second drive assembly 172. The head of second drive assembly 172 is pivotally connected to the cylinder of first drive assembly 171. Along the length of first drive assembly 171, a gap exists between the head of second drive assembly 172 and the pivotal connection between first drive assembly 171 and spreader body 170.

[0113] The second driving assembly 172 can drive the first driving assembly 171 to the departure position ( Figure 6 and Figure 7 , the solid line shows the position of the first drive assembly 171) and the connection position ( Figure 6 and Figure 7 , the dotted line shows the position of the first driving assembly 171). When the first driving assembly 171 is in the away position, the head of the first driving assembly 171 is away from the first sliding member 130. When the first driving assembly 171 is in the connected position, the head of the first driving assembly 171 can be connected to the operating portion 131 of the first sliding member 130. When the first driving assembly 171 is in the connected position, the length direction of the first driving assembly 171 is parallel to the height direction of the box body 110. In this way, the first driving assembly 171 can be used to drive the first sliding member 130 to move along the height direction of the box body 110.

[0114] like Figure 6 and Figure 7 As shown, a container transporting bulk cargo is moved to the spreader. At this point, the first slider 130 is in the sliding locking position, the bottom door 120 is in the closed position, and the hook 150 is in the hooked position. The spreader can be connected to the upper end of the container body 110. At this point, the second drive assembly 172 drives the first drive assembly 171 to rotate to the connection position, causing the head of the first drive assembly 171 to move to the operating portion 131 of the first slider 130, thereby connecting to the operating portion 131. In this way, the first drive assembly 171 can drive the first slider 130 to move in the height direction of the container body 110, thereby rotating the hook 150 to the unhooking position, thereby automatically opening the bottom door 120.

[0115] In this embodiment, the operating portion 131 of the first sliding member 130 can be connected to the operating portion 131 of the first sliding member 130 by a sling, thereby driving the first sliding member 130 to move along the height direction of the box body 110, so that the bottom door 120 can be opened. The operation of opening the bottom door 120 is simple, and there is no need to flip the box body 110 by a sling to unload the bulk cargo in the box body 110. The operation of unloading the bulk cargo in the box body 110 is simple and safe.

[0116] Preferably, the head of the first driving assembly 171 can be a connecting hook.

[0117] It is understandable that in an embodiment not shown, the first drive assembly may also be a T-shaped head or a rotary lock head.

[0118] Preferably, if Figure 7 As shown, the operating portion 131 is configured as an operating hole. Thus, the head of the first driving assembly 171 can be connected to the operating portion 131 by inserting the head into the operating hole, which is easy to operate.

[0119] The axis direction of the operation hole is parallel to the longitudinal direction (horizontal direction for example) of the box body 110. In this way, the opening of the operation hole faces the side of the box body 110 along the longitudinal direction of the box body 110. This makes it easy for the head of the first driving component 171 to extend into the operation hole.

[0120] It is understood that in an embodiment not shown, the axial direction of the bottom door's pivot axis may also be parallel to the width direction of the box body. In this case, the first sliding member is located on the side of the box body along the box body's width direction. In this case, the axial direction of the operating hole is parallel to the width direction of the box body 110. The operating hole opens to the side of the box body along the box body's width direction.

[0121] It will be appreciated that, in an embodiment not shown, the axis of the operating hole can be parallel to the height of the box. The opening of the operating hole faces upwards. In this case, the spreader only needs to be equipped with the first drive assembly. The length of the first drive assembly is parallel to the height of the spreader, allowing it to extend into the operating hole and connect to the first sliding member.

[0122] Please refer to Figure 7 The container also includes a lock 165. The lock 165 is movably connected to the container 110 along its length. When the first slider 130 is in the slide-locked position, the lock 165 faces the operation hole. This allows the lock 165 to extend into the operation hole. This secures the first slider 130 in the slide-locked position, preventing it from moving out of the slide-locked position.

[0123] The container also includes a lock elastic member 166. The lock elastic member 166 can be a cylindrical spring. The lock elastic member 166 is connected to the lock member 165 and the box body 110. The lock elastic member 166 is used to apply a force to the lock member 165 that enables the lock member 165 to enter the operating hole. In this way, under the action of the lock elastic member 166, when the first sliding member 130 moves to the sliding locking position, the lock member 165 can automatically extend into the operating hole. When the head of the first drive assembly 171 extends into the operating hole, the head of the first drive assembly 171 pushes the lock member 165 out of the operating hole, thereby unlocking the lock member 165 from the first sliding member 130.

[0124] Preferably, the lock 165 has a lock guide bevel 167. The upper end of the lock guide bevel 167 is further away from the center of the housing 110 than its lower end. Thus, when the first slider 130 moves from the slide-unlocked position to the slide-locked position, the first slider 130 contacts the lock guide bevel 167, causing the lock 165 to move along the length of the housing 110, thereby compressing the lock elastic member 166. The compressed lock elastic member 166 exerts a force on the lock 165, causing it to press against the first slider 130. When the lock 165 is aligned with the operating hole, the lock elastic member 166 acts to force the lock 165 into the operating hole. This facilitates the operation of the lock 165 into the operating hole.

[0125] It should be noted that the configuration of the container (including the structure of the box body 110, the structure and position of the lock hook 150, the structure and position of the connecting rod assembly 140, the structure and position of the first sliding member 130, and the structure and position of the bottom door 120) can enable the lock hook 150 to hook to the hooking portion 121 and enable the bottom door 120 to move to the closed position when the first sliding member 130 moves from the sliding unlocking position to the sliding locking position.

[0126] Second embodiment

[0127] Please refer to Figure 8 In the second embodiment, the first sliding member 230 in the slide-unlock position can be moved away from the slide-lock position to the slide-extended position. This increases the opening angle of the bottom door. As the bottom door moves from the slide-unlock position to the slide-extended position, the speed of the bottom door rotation is proportional to the movement speed of the first sliding member 230.

[0128] The container also includes a flexible member 261 and a second sliding member 265. The second sliding member 265 is movably connected to the container along its height. The container is also provided with a second guide rail. The length of the second guide rail extends along the height of the container. The second sliding member 265 is connected to the second guide rail. The second sliding member 265 cooperates with the second guide rail to guide the movement of the second sliding member 265 along its height. The second sliding member 265 is pivotally connected to the pivot member.

[0129] Flexible member 261 can be a chain or rope. One end of flexible member 261 is connected to connector 264, which in turn is connected to first slider 230 via connector 264. The other end of flexible member 261 is connected to second slider 265. Thus, flexible member 261 is connected to the locking hook via a pivot joint. Therefore, when the bottom door is closed, the first slider 230 applies force to the locking hook via flexible member 261, causing the hook to rotate to the hooked position. This simplifies the container's structure.

[0130] The container also includes a hook spring 262. This can be a cylindrical spring. One end of the hook spring 262 is connected to a connector 264, which in turn is connected to the first sliding member 230 via the connector 264. Along the height of the container, the hook spring 262 is positioned above a portion of the second sliding member 265.

[0131] As the first slider 230 moves from the slide-locked position to the slide-unlocked position, the hook elastic member 262 begins to contact the second slider 265. The first slider 230 continues to move toward the slide-unlocked position, compressing the hook elastic member 262. The first slider 230 exerts a downward force on the second slider 265 via the compressed hook elastic member 262. When the first slider 230 moves to the slide-unlocked position, this force causes the hook to rotate to the unhooked position.

[0132] When the first slider 230 is in the unlocked position, the hook elastic member 262 can still be compressed, allowing the first slider 230 to continue moving downward. Thus, as the first slider 230 moves from the unlocked position toward the extended position, the hook elastic member 262 continues to be compressed, further increasing the opening angle of the bottom door.

[0133] It is understood that, in an embodiment not shown, the other end of the locking hook elastic member may also be connected to the second sliding member, and then connected to the locking hook through the second sliding member.

[0134] Preferably, the locking hook elastic member 262 and the flexible member 261 do not protrude from the outer contour of the container, thereby facilitating the transportation of the container.

[0135] The other configurations of the second embodiment are substantially the same as those of the first embodiment and will not be described in detail here.

[0136] Third embodiment

[0137] Please refer to Figure 9In the third embodiment, the drive assembly includes a gear 371, a rack 372, a first drive wheel 373, a second drive wheel 374, a chain 375, and a manual portion 376 for manual operation (e.g., a crank handle). The gear 371 is rotatably connected to the housing. The rack 372 is connected to the first slider 330. The length of the rack 372 extends along the height of the housing. The gear 371 and the rack 372 mesh with each other. The first drive wheel 373 and the gear 371 are coaxially arranged and connected to the gear 371. In this way, the gear 371 and the first drive wheel 373 rotate together. The second drive wheel 374 is rotatably connected to the housing. The first drive wheel 373 and the second drive wheel 374 are sprockets. The chain 375 connects the first drive wheel 373 and the second drive wheel 374. In this way, the first drive wheel 373 and the second drive wheel 374 can rotate together. The manual portion 376 is connected to the second drive wheel 374 to rotate the second drive wheel 374.

[0138] A worker can manually operate the manual portion 376 to rotate the second drive wheel 374. The rotating second drive wheel 374 drives the first drive wheel 373 to rotate, which in turn drives the gear 371 to rotate. The rotating gear 371 drives the rack 372 to move along the height direction of the box, thereby driving the first sliding member 330 to move along the height direction of the box.

[0139] It is understood that in an embodiment not shown, the drive assembly includes a motorized portion. The motorized portion includes a pneumatic cylinder or a hydraulic cylinder. The motorized portion is connected to the box. The motorized portion is connected to the first slide to drive the first slide to move along the height direction of the box.

[0140] It will be appreciated that, in an embodiment not shown, the chain may be replaced by a belt. In this case, the first drive wheel and the second drive wheel are pulleys.

[0141] The gear 371, rack 372, first drive wheel 373, second drive wheel 374, and chain 375 do not protrude beyond the outer contour of the container. The manual unit 376 is detachably mounted. This allows for easy transport of the container. When needed, the manual unit 376 can be attached to the second drive wheel 374, facilitating container transport.

[0142] The other configurations of the third embodiment are substantially the same as those of the first embodiment and will not be described in detail here.

[0143] Fourth embodiment

[0144] like Figures 10 and 11As shown, in the fourth embodiment, the first sliding member 430 includes a sliding body 431 and a limiting portion 432. The limiting portion 432 is rotatably connected to the sliding body 431 between a blocking position and a moving position. The sliding body 431 is connected to the first guide rail for cooperation with the first guide rail. The box body is provided with a blocking portion 412. The blocking portion 412 is located on the outer side of the end wall away from the center of the box body. The blocking portion 412 is connected to the end wall. When the first sliding member 430 moves to the sliding locking position, the first sliding member 430 is located above the blocking portion 412 in the height direction of the box body. At this time, the limiting portion 432 is in the moving position. In the width direction of the box body, there is a gap between the limiting portion 432 in the moving position and the blocking portion 412. In this way, when the limiting portion 432 is in the moving position, the first sliding member 430 can move in the height direction of the box body.

[0145] When the first sliding member 430 moves to the slide locking position, the limiting portion 432 can rotate to the blocking position. The portion of the limiting portion 432 located at the blocking position is located directly above the blocking portion 412. In this way, the blocking portion 412 can prevent the first sliding member 430 from moving toward the slide unlocking position.

[0146] The other configurations of the fourth embodiment are substantially the same as those of the first embodiment and will not be described in detail here.
