Technical Field

The present invention relates generally to the field of containers, and more particularly, to an open cover structure and a container having the same.

Background

There are various ways to open the container roof in the existing hard open top containers. In the first mode, the top cover of the hard open top container is arranged separately from the container. Before loading and unloading goods, the top cover is lifted by using equipment such as a forklift, a crane and the like, and is placed at other places. The first mode needs extra space occupation operation and space for storing the top cover, and the box body or the top cover of the container is easy to damage when the top cover is assembled and disassembled; in the second mode, the top cover of the hard open top container is fixedly connected with the container through a hinge, and the top cover is turned over by about 270 degrees through external force or a transmission mechanism, so that the top cover is opened and closed. The second type of roof is generally thin and light and can only be used to cover or conceal the top opening of the container. Thus, the container has low sealing performance and is difficult to adapt to the watertight requirement of the container under severe transportation conditions such as high speed, bump and the like. The second top cover structure occupies more space when being turned over and cannot be completely opened in a narrow space.

Therefore, there is a need to provide an open cover structure and a container having the same to at least partially solve the above-mentioned problems.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in detail so as not to obscure the embodiments of the invention.

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

A preferred embodiment of the present invention provides an open cover structure. The open cover structure can be used for a container. The container may be a hard open top container. As shown in fig. 1 to 6, the container includes a body and a top opening 110 provided at the top of the body. The top opening 110 communicates with the interior space of the container. In this way, items to be transported can be loaded into and unloaded from the interior space of the container through the top opening 110. The door structure is used to open the top opening 110 of the container.

In other embodiments, not shown, the open-cover structure may also be used in the structures of cars of trains, trucks, and storage sections of ships, etc. The structures of a carriage of a train, a truck, and a storage section of a ship and the like have a box body, a top opening at the top of the box body, and a roof openably provided at the top opening at the top of the box body. The cover opening structure is used for opening the corresponding top opening.

In this embodiment, as shown in fig. 6, the container includes two top covers 120. The top cover 120 is movably disposed on the body of the container. The roof 120 is movable between an open position opening the top opening 110 of the container and a closed position closing the top opening 110 of the container. The top cover 120 includes a first side and a second side opposite the first side. The first side of each roof 120 faces the outside of the container when the roof 120 is in the closed position. The second sides of the two top covers 120 are oppositely disposed.

In this embodiment, the lid opening structure further includes a U-shaped shaft, a roller 190, and a bracket 200. The U-shaped shaft includes a first shaft 130, a second shaft 140, and a connecting portion 170. The first shaft 130, the second shaft 140, and the connecting portion 170 constitute a substantially U-shaped structure. The first shaft 130 and the second shaft 140 each extend along the length of the container. The connecting portion 170 of the U-shaped shaft is located outside the end of the top cover 120 (the side of the end of the top cover 120 facing the outside of the container) in the length direction of the container. The first axis 130 of the U-shaped shaft is located on the side of the roof 120 facing the top opening 110 of the container and abuts the lower surface of the roof 120 (the lower surface of the roof 120 in fig. 1). The second axis 140 of the U-shaped shaft is located on the side of the roof 120 remote from the top opening 110 of the container. Thus, the end of the roof 120 in the length direction of the container is located between the first shaft 130 and the second shaft 140. The first shaft 130 and the second shaft 140 can limit the movement of the top cover 120 in the height direction of the container, and prevent the top cover 120 from falling off the top of the container. The first side of the roof 120 is the side thereof that faces the outside of the container when in the closed position.

In this embodiment, the rollers include a first roller and a second roller. The first shaft 130 is rotatably sleeved with a first roller. The second shaft 140 is rotatably sleeved with a second roller. Thus, when the top cover 120 moves in the width direction of the container, the friction force when the top cover 120 moves is small. In other embodiments, the roller 190 may be sleeved only on the first shaft 130, or the roller 190 may be sleeved only on the second shaft 140.

In this embodiment, the bracket 200, the first shaft 130, and the first roller constitute a roof support. The first shaft 130 is connected to the top of the container by a bracket 200. The first roller is rotatably provided on the stand 200 by the first shaft 130. The connecting portion 170, the second shaft 140, and the second roller constitute a top cap limiting member. The second roller is rotatably connected to the connecting portion 170 by the second shaft 140. The connecting portion 170 and the second shaft 140 constitute a connecting member. Like this, top cap support piece, top cap locating part and connecting element integrated into one piece, the part quantity of structure of uncapping is few, simple structure.

In this embodiment, a U-shaped shaft is provided at both ends of each top cover 120 along the length direction of the container. Such that two U-shaped shafts act on the top cover 120 from both ends of the top cover. The top cover can be more effectively prevented from falling off the container. The coupling parts 170 of the U-shaped shaft located outside both ends of each top cover 120 can restrict the movement of the top cover 120 in the length direction of the container, thereby preventing the ends of the top cover 120 from coming off the U-shaped shaft. As shown in fig. 1-6, the first axle 130 may be located at the end of the top side beam of the container or at the end of the top end beam of the container. One first shaft 130 is provided at each end of each of the roof side rails in the present embodiment. This enables the top opening 110 of the container to be opened at a larger angle. The positions of the top side beams corresponding to the top cover 120 are provided with avoidance notches. When the top cover 120 is turned over, the avoidance notch on the top side beam avoids the top cover 120, so that the interference between the top cover 120 and the top side beam is avoided, and the turning of the top cover 120 is influenced.

In this embodiment, the roof support is rotatably arranged about its axis. Thus, the connecting portion 170 of the U-shaped shaft and the second shaft 140 are rotatable about the axis of the first shaft 130. In this manner, when the top cover 120 is turned over, the connecting portion 170 of the U-shaped shaft and the second shaft 140 can rotate about the axis of the first shaft 130.

In this embodiment, the end of the top cover 120 in the longitudinal direction of the container is movably inserted into the U-shaped shaft. Thus, the top cover 120 can be turned by pulling the hinge shaft 160 in the height direction of the container to move the hinge shaft between the later second position and the third position. At the moment, the top cover limiting piece rotates around the axis of the top cover supporting piece. During the turning of the top cover 120, the top cover 120 may be moved in the direction of its extension in the lengthwise direction of the container, thereby opening or closing the top opening 110 without opening the top cover 120 by a lifting device, the space required for opening or closing the top opening 110 is small, and it may be used to drive the top cover 120 having a large weight.

It is understood that in embodiments not shown, the top cover support, the top cover stop, and the connecting member may also be separate parts.

In the present embodiment, a sliding groove 122 is provided on a surface of the top cover 120 (an upper surface of the top cover 120 in fig. 1) away from the top opening 110. The chute 122 may be a C-shaped structure. When the top cover 120 closes the top opening 110, the chute 122 extends in the width direction of the container. The opening of the chute 122 is towards the outside of the end of the container. The second shaft 140 of the U-shaped shaft and the roller 190 fitted over the second shaft 140 are located in the opening of the C-shaped structure. Thus, the sliding groove 122 can provide a sliding way for the roller 190 sleeved on the second shaft 140.

In this embodiment, the opening structure includes a hinge arm, and the hinge arm is connected to the top cover 120. Specifically, both ends of the first side (left end in fig. 1) of the top cover 120 in the length direction of the container are respectively provided with one extension portion extending downward. The extensions constitute hinge arms of the top cover 120. At this time, the hinge arm and the top cover 120 are integrally formed. One slot 121 is provided on each extension. The elongated hole 121 penetrates the extension of the top cover 120 in the longitudinal direction of the container. The elongated hole 121 extends from the outside of the container to the inside of the container. The top end of the long hole 121 is farther from the inside of the container than the bottom end of the long hole. The door opening structure further includes a hinge shaft 160. The hinge shaft 160 is inserted into the long hole 121. The hinge axis 160 extends along the length of the container. Thus, when the plane of the top cover 120 is horizontal, the hinge shaft 160 is moved in the height direction of the container so that the hinge shaft 160 is moved at the first and second positions later, the hinge shaft 160 and the long hole 121 interact with each other, and the top cover 120 can be moved in the horizontal direction. In other embodiments, the hinge arms and the top cover 120 can be two separate pieces. At this time, the hinge arms and the top cover 120 are fixedly connected (e.g., the hinge arms may be welded to the top cover 120, or the hinge arms may be connected to the top cover 120 by bolts).

In this embodiment, the door opening structure further includes a driving part 150. The driving part 150 may be provided on the body of the container. The driving part 150 may be a motor, a lead screw connected to a motor shaft of the motor, and a nut engaged with the lead screw. The nut may be coupled with the hinge shaft 160. The lead screw extends in the height direction of the container. Thus, the motor drives the hinge shaft 160 to move in the height direction of the container through the lead screw and the nut. In other embodiments, the driving member 150 may be a cylinder or a hydraulic cylinder that is extendable and retractable in the height direction of the container.

In the present embodiment, the hinge shaft 160 is movable between the first position and the third position. Further, the second position is located between the first position and the third position. When the hinge axis 160 is in the first position, as shown in fig. 1, the plane in which the top cover 120 lies is substantially horizontal. The roof 120 closes the top opening 110 of the container. The seal 180 abuts the second side of the first cap. The hinge shaft 160 is located at the top end of the long hole 121; when the hinge axis 160 is in the second position, as shown in fig. 2, the plane in which the top cover 120 lies is substantially horizontal. The roof 120 closes the top opening 110 of the container. The seal 180 is distal from the second side of the first cap. The hinge shaft 160 is located at the bottom end of the long hole 121; with the hinge axis 160 in the third position, as shown in fig. 4, the top cover 120 opens the top opening 110 of the container. The hinge shaft 160 is located at the bottom end of the long hole 121. The top end of the long hole 121 is lower than the bottom end thereof in the height direction of the container.

In the present embodiment, when it is required to open the top opening 110 of the container (the top cover 120 of the container closes the top opening 110 of the container, as shown in fig. 1, the sealing member 180 abuts against the second side of the first top cover, and the hinge shaft 160 is located at the first position), the hinge shaft 160 is driven by the driving member 150 to move downward, and the hinge shaft 160 moves within the elongated hole 121 from the top end of the elongated hole 121 to the bottom end of the elongated hole 121 until the hinge shaft 160 moves to the bottom end of the elongated hole 121 (at this time, the hinge shaft 160 is located at the second position), as shown in fig. 2. In the process of moving the hinge shaft 160 from the top end of the long hole 121 to the bottom end of the long hole 121, the top cover 120 can be moved from the right side to the left side of fig. 1 in the horizontal direction by the action of the moving hinge shaft 160 on the inner wall surface of the long hole 121. This allows the seal 180 to be removed from the cap 120 against which it abuts.

After the hinge shaft 160 moves to the bottom end of the long hole 121 (at this time, the hinge shaft 160 is located at the second position), the downward movement of the hinge shaft 160 is continued by the driving member 150, as shown in fig. 3 and 4. When the hinge shaft 160 reaches the lower limit position (at this time, the top cover 120 is completely opened, and the hinge shaft 160 is located at the third position). In this process, the hinge shaft 160 moves from the second position to the third position. The top cover 120 slides diagonally downward between the first shaft 130 and the second shaft 140 while the top cover 120 is turned in the direction E of fig. 3. In this process, the first shaft 130 and the second shaft 140 rotate together with the top cover 120.

In this embodiment, when the top cover 120 is fully opened, the top opening 110 of the container is closed if necessary. The hinge shaft 160 may be driven to move upward by the driving member 150. During the upward movement of the hinge shaft 160, the hinge shaft 160 moves from the third position to the second position. The top cover 120 is flipped in the direction opposite to direction E of fig. 3 until the top cover 120 is flipped to the level of the plane in which it lies. During this process, the top cover 120 slides obliquely upward between the first shaft 130 and the second shaft 140.

When the plane on which the top cover 120 is positioned is substantially horizontal (at this time, the hinge shaft 160 is located at the second position), the hinge shaft 160 continues to be moved upward by the driving member 150 until the hinge shaft 160 moves to the top end of the long hole 121, as shown in fig. 5 and 6. In this process, the action of the moving hinge shaft 160 on the inner wall surface of the long hole 121 can move the top cover 120 from the left side to the right side in fig. 5 in the horizontal direction of the top cover 120. This may allow the seal 180 to abut the first cap.

As shown in fig. 6, in the illustrated embodiment, the top cover 120 includes a first top cover and a second top cover. The first roof is located on one side of the top of the container when the roof 120 is in the closed position. The second roof is located on the other side of the top of the container. The first roof and the second roof are arranged side by side in the width direction of the container to cover the top opening 110 of the container. It will be appreciated that in embodiments not shown, the first roof is located at one end of the roof of the container when the roof 120 is in the closed position. The second roof is located at the other end of the top of the container. The first roof and the second roof are arranged side by side along the length of the container to cover the top opening 110 of the container.

The invention also provides a container. The container is the container. The container includes the aforementioned door opening structure and the sealing member 180, and a sealing seat for connecting the sealing member 180. The seal receptacle is coupled to the second side of the second cap. The seal 180 is attached within the seal seat. When the roof 120 closes the top opening 110 of the container, the seal 180 abuts the second side of the first roof to seal the gap between the second sides of the two roofs 120.

According to the container of the present invention, the container includes the aforementioned opening structure, the top cover 120 can be turned over and the top cover 120 can be moved in the horizontal direction by pulling the hinge shaft 160 in the height direction of the container, thereby opening or closing the top opening 110 of the container body without opening the top cover 120 by a lifting device, the space required for opening or closing the top opening 110 of the container body is small, and the container can be used to drive the top cover 120 having a large weight.
