In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present application. It is apparent that the implementation of the embodiments of the present application is not limited to the specific details familiar to those skilled in the art. The following detailed description of the preferred embodiments of the present application, however, the present application may have other embodiments in addition to these detailed descriptions.

First embodiment

The present application provides a container. The container may be used for transporting bulk cargo. The bottom of the container body 120 may be opened to discharge the cargo within the body 120. The top end of the case 120 removably covers a top cover 140. Thus, dust emission can be reduced when bulk cargo is discharged.

Referring to fig. 1 to 12, the container includes a container pivot axis 110 and a container 120. The case 120 includes two sub-cases. The sub-enclosure comprises a base 127, one end wall 125 and two side walls 126. The chassis 127 is configured as a generally rectangular structure. An end wall 125 is connected to one end of the chassis 127 along the length of the chassis 127. The side wall 126 is connected to a side of the bottom chassis 127 in a width direction of the bottom chassis 127. Thus, the bottom frame 127, one end wall 125, and two side walls 126 are configured as a generally rectangular parallelepiped structure. The end wall 125 is located at one end (an example of an outer end) of the sub-tank in a length direction of the sub-tank. The inner end of the sub-tank, which is away from the outer end, has an end opening 123 along the length of the sub-tank. The top end of the sub-tank has a top opening 124. The end opening 123 and the top opening 124 communicate.

Referring to fig. 1 to 3 and 5, the axial direction of the box pivot axis 110 is parallel to the width direction of the sub-box. The top of the end of the side wall 126 remote from the end wall 125 is provided with a through hole along the length of the sub-tank. The box pivot shaft 110 is disposed through the through hole. The through hole is a circular hole. Thus, the inner ends of the two sub-housings are pivotally connected by the housing pivot shaft 110. In this manner, both sub-housings can rotate about the housing pivot axis 110 to provide the housing 120 with a closed state and an open state.

As shown in fig. 2, 8, 9 and 11, when the box 120 is in the closed state, the edges of the inner ends of the two sub-boxes are completely connected to close the end openings 123 of the two sub-boxes. In this case, the two sub-cases form a substantially rectangular parallelepiped structure.

As shown in fig. 1 and 10, when the box 120 is in the open state, there is a gap between the lower portions of the inner ends of the two sub-boxes. Thus, the end openings 123 of the two sub-housings are opened, and the bulk cargo in the housing 120 can be discharged through the end openings 123 of the sub-housings.

Referring to fig. 1, 2 and 6, the container further includes a roof pivot axis 130 and two roofs 140. The two top covers 140 and the two sub-cases are arranged in one-to-one correspondence. The top cap 140 is removably connected to the top end of the sub-case corresponding thereto to cover the top opening 124 of the sub-case corresponding thereto.

The axial direction of the top cover pivot axis 130 is parallel to the axial direction of the case pivot axis 110. The ends of the two caps 140 near each other are pivotally connected by the cap pivot shaft 130.

The top cover pivot axis 130 is located directly above the case pivot axis 110. Thus, during the transition between the opened and closed states of the case, the top cover 140 rotates together with the corresponding sub-case. Thus, when the box 120 is switched from the closed state to the open state to discharge the bulk cargo, the top cover 140 always covers the top opening 124 of the corresponding sub-box, so that the dust generated during discharging can be reduced as much as possible.

Specifically, with continued reference to fig. 1 and 2, the two caps 140 include a first cap 141 and a second cap 142. The two sub-housings include a first sub-housing 121 and a second sub-housing 122. The first top cover 141 is disposed corresponding to the first sub-case 121. The second top cover 142 is disposed corresponding to the second sub-tank 122. The first top cover 141 is removably coupled to a top end of the first sub-case 121 to cover the top opening 124 of the first sub-case 121. The second top cover 142 is removably coupled to a top end of the second top cover 142 to cover the top opening 124 of the second sub-tank 122.

When the first sub-housing 121 rotates around the housing pivot axis 110 relative to the second sub-housing 122, the first sub-housing 121 drives the first top cover 141 to rotate around the top cover pivot axis 130 relative to the second top cover 142. When the second sub-case 122 rotates around the case pivot 110 relative to the first sub-case 121, the second sub-case 122 drives the second cover 142 to rotate around the cover pivot 130 relative to the first cover 141.

The arrangement that the top cover pivot shaft 130 is positioned right above the box body pivot shaft 110 can reduce the degree of downward depression of the position of the top cover 140 connected with the top cover pivot shaft 130 as much as possible, thereby reducing water accumulation or material accumulation at the position of the top cover 140 connected with the top cover pivot shaft 130.

It should be noted that when the two sub-cases rotate relative to each other about the case pivot axis 110, the top cover covering the top end of the sub-case is slidable relative to the sub-case along the length direction of the sub-case. The inner end of the sub-tank is provided with a connection portion (not shown). The connecting part is connected to the end part of the top cover corresponding to the sub-box body, which is close to the box body pivot shaft, so as to block the movement of the end part of the top cover, which is close to the box body pivot shaft, along the length direction of the sub-box body. The connection between the connection part and the top cover can be released. Thus, when the top cover needs to be removed to load and unload goods into the box body, the connection between the top cover and the connecting part can be released, so that the top cover can be removed. For example, the connection portion may be a connection lug. The connecting lug is provided with a lug through hole. The top cover 140 is detachably provided with a connecting shaft (not shown) coaxial with the top cover pivot shaft 130. The connecting shaft is rotatably arranged in the ear through hole in a penetrating way.

In this embodiment, the box 120 is switched from the closed state to the open state, so that the top cover 140 always covers the top opening 124 of the corresponding sub-box during the process of unloading the bulk cargo, thereby reducing the dust generated during the unloading process as much as possible.

Preferably, as shown in fig. 1 to 4, the container further comprises a lifting assembly 150. The lifting assembly 150 is connected to the top end of the sub-tank. The hoist assembly 150 includes an end hoist assembly 151 and a middle hoist assembly 152. The end lifting unit 151 is located at a side of the sub-chamber away from the inner end of the ion chamber in the center of the setting direction. The mid-hoist assembly 152 is located on the side of the center near the box pivot axis 110. The axial direction of the box pivot axis 110 and the height direction of the sub-box are both perpendicular to the setting direction. Thus, the arrangement direction is parallel to the length direction of the sub-case.

As shown in fig. 8 to 11, the lifting device 170 is connected to the end and middle lifting assemblies 151 and 152 by flexible members (ropes or chains). The flexible member to which the end hoist assembly 151 is attached is an end flexible member 172. The flexure to which the mid-lift assembly 152 is attached is a mid-flexure 171.

Referring to fig. 8 to 10, when the box 120 is in the closed state, the hoisting device 170 hoists the end hoisting assembly 151 through the end flexible member 172, and the box 120 is converted from the closed state to the open state and is kept in the open state. Referring to fig. 10 and 11, when the box body 120 is in the open state, the hoisting device 170 hoists the middle hoisting assembly 152 through the middle flexible member 171, so that the box body 120 can be converted from the open state to the closed state and can be kept in the closed state. This simplifies the operation of opening or closing the case 120.

It is further preferred that the end hoist assembly 151 is located at the outer end of the sub-tank. The mid-hoist assembly 152 is located at the box pivot axis 110. The mid-hoist assembly 152 is attached to one of the two sub-tanks. Thereby, it is convenient to make the case 120 in an opened state or a closed state.

As shown in fig. 1 to 3, the end-user lifting assembly 151 is plural. A partial end hoist assembly 151 is attached to the top end of the end wall 125 of the sub-tank. The other end hoist assembly 151 is connected to the top end of the side wall 126 of the sub-tank.

Referring to fig. 2 and 4, the hoisting assembly 150 includes a hook member 153 and a limiting member 154. The hook 153 is connected to the outer side of the sub-tank. The stopper 154 is pivotally connected to the hook 153. Thus, the stop 154 is rotatable between a closed position and an open position.

With the stopper 154 in the closed position, one end of the stopper 154 abuts against the free end of the hooking portion of the hooking member 153, thereby closing the opening of the hooking member 153. With the limiting member 154 in the open position, the limiting member 154 is away from the free end of the hooking portion of the hooking member 153 to open the opening of the hooking member 153.

The end of the flexible member is configured as a circumferentially closed annular structure. By positioning the limiting member 154 at the open position, the loop structure of the flexible member can be sleeved on the hook portion of the hook member 153 through the opening of the hook member 153. The stop member 154 is in the closed position, so that the flexible member is prevented from being separated from the hooking member 153.

Further preferably, the opening of the hooking piece 153 faces downward. Therefore, the flexible piece can be connected to the hook part more conveniently.

Further preferably, as shown in fig. 4, the hoist assembly 150 further comprises a hook return spring 155. The hook return spring 155 may be a torsion spring. The hook return spring 155 is connected to the hook member 153 and the stopper 154. The hook return spring 155 is in a deformed state. The hook return spring 155 in the deformed state can apply an urging force to the stopper 154. This force can move the stop 154 away from the open position. This automatically moves the stopper 154 away from the closed position to the closed position, and the stopper can be held at the closed position.

Further preferably, the limiting member 154 is further provided with an operating portion 157. The operator can hold the operation portion 157 to rotate the limiting member 154. Thus, the stopper 154 is easily operated.

Preferably, referring to fig. 2, 8-11, the shipping container further includes a lock assembly 160. The latch assembly 160 includes a locking portion 161 and a latch 162 connected to a lower end of the sub-tank. In a case where the case 120 is in the closed state, the locker 162 is detachably coupled to the locking part 161 to lock the case 120 in the closed state. Thus, the case 120 in the closed state can be prevented from being shifted toward the open state.

As shown in fig. 2, end hoist assembly 151 includes an end slide 156. The hook 153 of the end hoist assembly 151 is connected to an end slide 156. An end slide 156 is attached to the top end of the side wall 126 of the sub-tank. The end slider 156 is movably disposed between an end slide unhooking position and an end slide hooking position in the height direction of the sub-tank. It will be appreciated that the end slides 156 may be attached to the side walls 126 of the sub-tank by means of long holes. The long axis of the long hole is parallel to the height direction of the sub-tank connected to the end slider 156. The end slides 156 may also be attached to the side walls 126 of the sub-tanks by slides. The length direction of the runners is parallel to the height direction of the sub-housings connected to end slides 156.

With continued reference to fig. 2, the end slider 156 is connected to a latch 162. Thus, the end slider 156 moves along the height of the sub-box to move the lock 162. In the process of moving the end slider 156 from the end slide hooking position to the end slide unhooking position, the end slider 156 carries the lock 162 away from the locking portion 161 to unlock the case 120 in the closed state.

As shown in fig. 8 and 11, the end flexible member 172 is connected to the hooking member 153 connected to the end slider 156. The hooking member 153 is lifted upward to move the end slider 156 located at the end slide hooking position upward to the end slide unhooking position. At this time, the locker 162 is separated from the locking part 161 to unlock the case 120 in the closed state. In this way, the two sub-housings can be rotated relative to each other about the housing pivot axis 110. The hooking member 153 continues to be lifted upward. At this time, the hook 153 lifts the outer end of the driver case by the end slider 156 to rotate the two sub cases relative to each other, thereby shifting the case 120 from the closed state toward the open state. Thus, the end slider 156 and the lock 162 are interlocked, so that the lock of the case 120 in the closed state can be released at the same time by the operation of the case 120 from the closed state to the open state, and the operation is simple.

The end slider 156 is movably connected to the sub-tank in the height direction of the sub-tank between an end slide unhooking position and an end slide hooking position. Thus, it is not necessary to provide a corresponding structure to convert the direction of the force, and the structure of the case 120 is simple.

As shown in fig. 2, the locking portion 161 is configured as a lock pin. The locking pin is coupled to the sidewall 126 of the first sub-case 121 and protrudes to the outside of the sidewall 126 of the first sub-case 121. The end slider 156 is connected to the second sub-tank 122. The latch 162 includes a hook stem 163. The hooking rod 163 is located outside the second sub case 122 away from the center of the second sub case 122. The head end of the hook lever 163 is provided with a hook head 164. The opening of the hook head 164 faces upward. The hook head 164 is configured in a circular arc shape. The hook head 164 is used to hook the locking pin from bottom to top. A trailing end 166 of the hook lever 163 remote from the hook head 164 is pivotally connected to the end slide 156. Thus, the end slider 156 moving in the height direction of the second sub-tank 122 can bring the trailing end 166 of the hook lever 163 to move in the height direction of the second sub-tank 122. The hooking rod 163 is provided with a pivoting portion 165. The pivot 165 is located between the trailing end 166 and the hook head 164. The hook lever 163 is rotatably connected to the sidewall 126 of the second sub-tank 122 by the pivot 165.

With continued reference to fig. 2, the latch 162 further includes a resilient member 167. The elastic member 167 may be a cylindrical spring. The elastic member 167 is located at a side of the hook lever 163 away from the lower end of the second sub-tank 122. One end of the elastic member 167 is connected to a portion of the hook lever 163 between the pivot 165 and the hook head 164. The other end of the elastic member 167 is connected to the second sub-tank 122. The elastic member 167 is in a stretched state to be able to apply a force (pulling force) to the hook lever 163 to hook the hook head 164 to the lock pin. Thus, when the hook head 164 is separated from the lock pin, the elastic member 167 can rotate the hook lever 163 to be hooked to the lock pin.

As shown in fig. 8-11, the lifting device 170 is connected to the end lifting assembly 151 by an end flexure 172. The lifting device 170 is connected to the central lifting assembly 152 by a central flexible member 171.

As shown in fig. 8 and 9, when the box 120 is in the closed state of the box 120, the lifting device 170 applies an upward force to the end flexible member 172 to keep the end flexible member 172 in a stretched state. In this way, the lifting device 170 lifts the hook 153 connected to the end slide 156 upward via the end flexure 172 connection, thereby moving the end slide 156 from the end slide hooking position to the end slide unhooking position. In this process, the hook lever 163 rotates in the counterclockwise direction about the pivot 165 to disengage the hook head 164 from the latch to unlock the cabinet 120 in the closed state. In the process, the lifting device 170 exerts no force on the central flexure 171, so that the central flexure 171 is in a collapsed state.

As shown in fig. 10, the hook 153 is further lifted upward, and the hook 153 lifts the outer end of the driver case by the end slider 156 to rotate the two sub cases relative to each other, thereby shifting the case 120 from the closed state toward the open state. At this point, the lifting apparatus 170 may lift the other end lifting assemblies 151. In the process, the end flexures 172 are in a straightened state and the lifting device 170 exerts no force on the central flexure 171, leaving the central flexure 171 in a collapsed state.

As shown in fig. 10 and 11, when the box 120 is in the open state, if the box 120 needs to be in the closed state, the hoisting device 170 applies an upward force to the middle flexible member 171, so that the middle flexible member 171 is in a stretched state. In this way, the lifting device 170 lifts the mid-lift assembly 152 upward through the mid-flexible member 171. The lifting device 170 releases the force on the end flexure 172 to place the end flexure 172 in a collapsed state.

When the lifting device 170 releases the force on the end flexible member 172, the end slider 156 moves downward under its own weight to rotate the hook lever 163 clockwise about the pivot 165, thereby rotating the hook head 164 to a position where it can hook the lock pin. In the process, the pulling force of the elastic member 167 also rotates the hook lever 163 clockwise about the pivot 165, thereby rotating the hook head 164 to a position where the latch can be hooked.

The lifting device 170 lifts the middle of the box body 120 through the middle flexible member 171 to convert the box body 120 from the open state to the closed state. When the cabinet 120 is to be switched to the closed state, the extrados of the hook head 164 of the hook lever 163 away from the tail end 166 of the hook lever 163 contacts the lock pin. At this time, the hook lever 163 rotates counterclockwise about the pivot 165 by the action of the lock pin on the hook head 164, so that the lock pin slides along the extrados surface of the hook head 164 into the opening of the hook head 164 with respect to the hook head 164. In this way, the hook head 164 can hook the lock pin.

Preferably, as shown in fig. 12, the free end of the circular arc shape is provided with a guide surface 168. When the housing 120 is to be switched to the closed state, the lock pin slides along the guide surface 168. At this point, the locking pin slides along the guide surface 168 into the opening of the hook head 164 under the action of the guide surface 168. Therefore, the operation is convenient.

The elastic member 167 is provided so that the hook head 164 can be hooked to the lock pin and maintain the hooked state to the lock pin.

It can be understood that the time of applying the upward acting force to the middle flexible part and the time of releasing the acting force to the end flexible part can be controlled, so that when the box body is in the closed position, the hook rod rotates, the hook head is hooked to the lock pin, and the collision between the lock pin and the hook head is avoided.

Preferably, the container further comprises a box seal (not shown). The case seal is connected to one of the two sub-cases. With the case 120 in the closed state, one sub-case compresses the case seal to the other sub-case to seal the gap between the two sub-cases. Thereby, leakage can be avoided.

The hooking part 153 extends to the upper side of the sub-tank. The portion of the top cover 140 distal from the end of the case pivot axis 110 is recessed toward the case pivot axis 110 to form an escape notch 144. The relief notch 144 is located at a hanger assembly 150 attached to the end wall 125 of the subbox along the width of the subbox. Thus, in the case of a transfer from the open to the closed configuration of the enclosure, the access opening 144 allows access to the hanger assembly 150 attached to the end wall 125 of the sub-enclosure.

As shown in fig. 7, the top cap 140 is also provided with a top cap seal 180. When the top cover 140 covers the corresponding sub-box, the top cover 140 presses the top cover sealing member 180 to the top end of the corresponding sub-box to seal the gap between the top cover 140 and the corresponding sub-box.

As shown in fig. 1, the top cover 140 is provided with top cover fork grooves 143. The bottom end of the sub-tank is provided with a tank fork 128. Thereby facilitating movement of the sub-housings and facilitating movement of the top cover 140.

Second embodiment

In the second embodiment, referring to fig. 13, the elastic member 267 is located at a side of the hook rod 163 near the bottom end of the second sub-housing. One end of the elastic member 267 is connected to a portion of the hooking rod 163 between the pivoting portion 265 and the trailing end 266. The other end of the elastic member 267 is connected to the sub-housing. The elastic member 267 is in a stretched state to apply a tensile force to the hooking rod 163.

Other configurations of the second embodiment are substantially the same as those of the first embodiment, and are not described herein again.

Third embodiment

As shown in fig. 14, in the third embodiment, the case pivot axis 310 protrudes outside the side wall of the sub-case from the center of the ion case in the width direction of the sub-case to constitute a middle hoist assembly. From this, middle part hoist and mount subassembly's simple structure.

The end hoist assembly 351 is configured as a hoist shaft. The axial direction of the hoisting shaft is perpendicular to the height direction of the sub-box body connected with the hoisting shaft. Along the axial direction of the hoisting shaft, the hoisting shaft protrudes to the outer side of the sub-box body connected with the hoisting shaft. Therefore, the end hoisting assembly is simple in structure.

Other configurations of the third embodiment are substantially the same as those of the first embodiment, and are not described herein again.

Fourth embodiment

As shown in fig. 15, in the fourth embodiment, both the sub-cases are provided with a lock portion 461. The locking portion 461 is a locking plate. The locking plate is connected to a lower end of the side wall of the sub-case and is located outside the side wall. The locking portion 461 is provided with a locking hole 462. The axial direction of the locking hole 462 of the locking portion 461 is parallel to the height direction of the sub-tank connected thereto.

The lock includes a pin 464 and a flexible connector 468. Under the condition that the box body is in a closed state, the two locking plates are sequentially arranged along the height direction of the box body. When the case is closed, the lock holes 462 of the two lock plates are substantially coaxial. At this time, the pin 464 may be detachably inserted through the two locking holes 462 to lock the case in the closed state. The flexible coupling 468 may be a rope or a chain. The second sub-tank is provided with a guide wheel (not shown) for changing the extending direction of the flexible coupling 468. The guide wheels can be arranged as required. One end of the flexible connector 468 is connected to the pin 464. The other end of flexible link 468 is connected to end slide 463. Thus, in the process of moving the end sliding piece 463 from the end sliding hooking position to the end sliding unhooking position, the movement of the end sliding piece 463 can drive the pin 464 to move via the flexible connecting member 468, so that the pin 464 leaves the locking hole 462, thereby releasing the locking of the closed box. Therefore, the lock assembly is simple in structure.

Other configurations of the fourth embodiment are substantially the same as those of the first embodiment, and are not described herein again.

Fifth embodiment

As shown in fig. 16, the lock assembly includes a jensen coupler 561. The jensen coupler 561 is a prior art jensen coupler for a train. The jensert 561 includes a pin 564. Pin 564 is connected to end slide 563 by flexible connection 568. In this way, the end slide 563 is able to move the pin 564 upwards via the flexible link 568 to unlock the jensen coupler 561.
