DETAILED DESCRIPTION

[0043] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as limiting the present invention.

[0044] Terms such as "upper", "above", "lower", "below", etc. used in this embodiment to indicate relative positions in space are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. Terms of relative positions in space may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings. For example, "upper", "lower", "left", "right", "horizontal", and "vertical" in this embodiment are all relative positions in space when the container is in normal use.

[0045] The terms first, second, third, fourth, etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated; in addition, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, the connection can be a direct connection or an indirect connection through an intermediate medium, and can be a fixed connection or a movable connection or a detachable connection or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In order to enable those skilled in the art to better understand the technical solution of the present invention, the first direction is defined as the length direction of the container, and the second direction is defined as the width direction of the container. Figure 1 -11. Provide a clear and complete description of the technical solutions in the implementation modes of the present invention.

[0047] One embodiment of the present invention provides a container. The container in this embodiment may be an open-top container, and the box body 10 is a roughly rectangular parallelepiped structure. The container includes a box body 10 and a top cover. The box body 10 may include a bottom plate, a top plate 12, and four side plates (only the relevant structure of the top plate 12 is shown in the figure) connected to each other. The bottom plate is parallel to the top plate 12, and the side plates are perpendicular to the bottom plate and the top plate 12. Thus, the bottom plate, the top plate 12, and the four side plates enclose the box body 10 structure.

[0048] A feed port 30 is provided on the top plate 12. In the present embodiment, only one feed port 30 is provided on the top plate 12. The feed port 30 can be set to be rectangular. The area of ​​the feed port 30 can be the area of ​​the top plate 12 scaled in proportion. Bulk granular cargo such as mud and sand can be loaded into the container through the feed port 30.

[0049] The top cover is pivotally connected to the top plate 12, and is located at one side of the feed port 30. The top cover rotates between an open position and a closed position. When the top cover is in the open position, the feed port 30 is open, and the goods can be loaded into the container from the feed port 30. When the top cover is in the closed position, the feed port 30 is closed, and the top cover seals the feed port 30, thereby preventing rainwater from entering the box body 10 from the feed port 30.

[0050] At least two top covers are arranged along the length direction of the feed inlet 30, and two adjacent top covers overlap each other. A locking structure 40 is provided on the top plate 12, and the locking structure 40 is provided on one side of the feed inlet 30, and the locking structure 40 is adapted to the top cover structure. When the top cover is in a closed state, the locking structure 40 can press against the upper surface of the top cover, play a role in limiting and fixing the top cover, and can ensure that the top cover seals the feed inlet 30.

[0051] The top cover is provided with a plurality of upwardly concave convex structures arranged at intervals along the first direction, so that the cross section of the top cover along the first direction is a plurality of continuous bending structures, forming a corrugated plate structure. In this way, the mechanical strength of the top cover is higher, and the top cover is not easily deformed by force during the transportation of the container, and can play a better role in sealing the feed port 30.

[0052] The top cover is provided with a sealing structure, which has a transverse portion 51, a longitudinal portion 52 and a connection box 53. It is relatively easy to understand that the transverse portion 51 extends along the first direction, the longitudinal portion 52 extends along the second direction, and the connection box 53 is arranged at the intersection of the transverse portion 51 and the longitudinal portion 52. Thus, the transverse portion 51 can play a sealing role in the length direction of the top cover, the longitudinal portion 52 can play a sealing role in the width direction of the top cover, and the connection box 53 can ensure the sealing effect of the intersection position of the transverse portion 51 and the longitudinal portion 52, so that the top cover has a better sealing effect on the feed port 30.

[0053] Since two adjacent top covers need to overlap each other to achieve sealing, the structures of the two adjacent top covers are different. As an example, in this embodiment, two of the top covers are used as examples for description. One of the top covers is the first top cover 21, and the other top cover is the second top cover 22, and part of the structure of the second top cover 22 is overlapped on part of the structure of the first top cover 21.

[0054] The longitudinal portion 52 includes a first back beam 521 disposed at the edge of the first top cover 21 and a second back beam 522 disposed at the edge of the second top cover 22. Both the first back beam 521 and the second back beam 522 extend in the first direction, and the second back beam 522 is arranged above the first back beam 521. A first longitudinal sealing member 523 is connected to the bottom of the second back beam 522, and the first back beam 521 tilts up toward the second back beam 522 on one side of the second top cover 22. When the second top cover 22 is overlapped above the first top cover 21, the tilted portion of the second back beam 522 can be sealed and matched with the first longitudinal sealing member 523. Therefore, sealing between the first top cover 21 and the second top cover 22 can be achieved.

[0055] The first back beam 521 includes an integrally arranged first bending plate 5211 and a protruding plate 5212, wherein the first bending plate 5211 is fixedly connected to the bottom wall of the first top cover 21, and the protruding plate 5212 is arranged on a side of the first bending plate 5211 close to the second top cover 22. The upper edge of the protruding plate 5212 is higher than the first bending plate 5211, and the position where the protruding plate 5212 is flush with the first bending plate 5211 is fixedly connected to the side end of the first top cover 21, and the portion of the protruding plate 5212 higher than the first bending plate 5211 is located above the first top cover 21. Thus, the first bending plate 5211 and the protruding plate 5212 form a groove-shaped structure with an opening upward, and the protruding plate 5212 tilts toward the direction of the second back beam 522.

[0056] It should be noted that the raised structure in the first top cover 21 can form a water guide trough structure with the protruding plate 5212, which can guide the rainwater accumulated on the top cover and drain it quickly.

[0057] The second top cover 22 is integrally provided with a mounting portion 221 with an opening downward at an edge position facing the first top cover 21. The second back beam 522 includes an integrally provided second bending plate 5221 and a mounting groove 5222. The second bending plate 5221 is fixedly connected to the bottom wall of the second top cover 22, and the mounting groove 5222 is provided on a side of the second bending plate 5221 close to the first top cover 21. The shape and size of the mounting groove 5222 match the mounting portion 221, and the mounting groove 5222 is fixedly connected to the bottom wall of the mounting portion 221. The first longitudinal seal 523 is sealingly connected to the bottom of the mounting groove 5222.

[0058] When the first top cover 21 and the second top cover 22 are closed, the first top cover 21 is closed first, and then the second top cover 22 is closed. The first longitudinal sealing member 523 at the bottom of the second top cover 22 abuts against the upper edge of the protruding plate 5212, thereby sealing the gap between the first top cover 21 and the second top cover 22 and blocking rainwater.

[0059] The transverse portion 51 includes a transverse sealing beam 511 disposed at the edge of the top cover and a transverse sealing member 512 disposed in the transverse sealing beam 511. The transverse sealing beam 511 is configured as a groove structure with an opening facing downward, and the transverse sealing member 512 is connected inside the transverse sealing beam 511.

[0060] The transverse sealing beam 511 includes a mounting plate 5111, an edge plate 5112 and a fixing plate 5113, and the mounting plate 5111, the edge plate 5112 and the fixing plate 5113 are integrally formed. The mounting plate 5111 is fixedly connected to the first top cover 21, or can be integrally connected.

[0061] The mounting plate 5111 is arranged horizontally, and the edge plate 5112 and the fixing plate 5113 are respectively arranged on both sides of the mounting plate 5111 in the first direction, and the edge plate 5112 and the fixing plate 5113 are perpendicular to the mounting plate 5111. Thus, the edge plate 5112, the mounting plate 5111 and the fixing plate 5113 define a receiving groove opening downward, and the transverse sealing member 512 is sealed and fixed to the bottom of the mounting plate 5111.

[0062] The lower end of the edge plate 5112 extends downward to the bottom of the transverse seal 512 . The transverse sealing beam 511 can protect the transverse seal 512 and can avoid rainwater from directly contacting the transverse seal 512 as much as possible, thereby ensuring the service life of the transverse seal 512 .

[0063] A convex beam 121 is arranged at the top of the top plate 12 along the edge of the feed port 30. The convex beam 121 includes two first parts 1211 extending along the first direction and two second parts 1212 extending along the second direction. The two first parts 1211 and the two second parts 1212 enclose a frame-shaped convex structure whose shape and size match the feed port 30.

[0064] The first top cover 21 and the second top cover 22 are both provided with the above-mentioned transverse parts 51 on the opposite side edges along the second direction. When the first top cover 21 and the second top cover 22 are closed, the transverse sealing beam 511 can cover the top of the first part 1211, so that the transverse sealing member 512 is sealed and pressed to the upper end edge of the first part 1211 to realize transverse sealing.

[0065] In a specific implementation process, if N top covers are provided, the edge positions of the first top cover and the Nth top cover are provided with edge sealing portions 54 that cooperate with the second portion 1212 of the convex beam 121. If only two top covers are provided, such as the first top cover 21 and the second top cover 22 described above, the edge sealing portions 54 are provided at the edge of the first top cover 21 away from the second top cover 22 and at the edge of the second top cover 22 away from the first top cover 21.

[0066] The edge sealing portion 54 includes a third sealing beam 541 fixedly connected to the edge position of the top cover, and a second longitudinal sealing member 542 sealed to the bottom of the third sealing beam 541. The third sealing beam 541 cooperates with the second portion 1212, and when all the top covers are closed, the second longitudinal sealing member 542 at the bottom of the first top cover and the Nth top cover can be sealed against the upper edge of the second portion 1212 to achieve longitudinal sealing of the edge position.

[0067] The connection box 53 has a transition surface connecting the transverse portion 51 and the longitudinal portion 52. In the height direction, one end of the transition surface is flush with the transverse portion 51, and the other end of the transition surface is flush with the longitudinal portion 52 to make up for the height difference between the transverse portion 51 and the longitudinal portion 52. An intersection seal 55 is provided in the connection box 53. The intersection seal 55 is provided at the intersection of the transverse portion 51 and the longitudinal portion 52, so that the seals in the transverse portion 51 and the longitudinal portion 52 are intersected or matched at the position of the connection box 53, so that the corner position between adjacent top covers has a better sealing and waterproof effect.

[0068] The connection box 53 includes a receiving plate 531 disposed at a corner of the top cover. Taking the first top cover 21 and the second top cover 22 as an example, the receiving plate 531 is fixedly connected to the intersection of the second back beam 522 and the transverse sealing beam 511.

[0069] The receiving plate 531 has a receiving area 5311 fixedly connected to the second back beam 522 and a transition area 5312 fixedly connected to the transverse sealing beam 511. The transition area 5312 is the above-mentioned transition surface, and the receiving area 5311 and the transition area 5312 are integrally arranged. The shape of the edge of the receiving area 5311 facing the first top cover 21 matches the shape of the first mounting groove 5222. The transition area 5312 gradually tilts downward from the receiving area 5311 toward the transverse sealing beam 511, so that the transition area 5312 can be connected to the end of the transverse sealing beam 511.

[0070] The intersection seal 55 includes a first extension seal strip 551 and a second extension seal strip 552 connected to each other. The first extension seal strip 551 is arranged at both ends of the first longitudinal seal 523 along the second direction, and the first extension seal strip 551 is fixedly connected to the bottom of the receiving area 5311 and is flush with the first longitudinal seal 523. The second extension seal strip 552 is arranged at one end of the transverse seal 512 along the first direction, and the second extension seal strip 552 is fixedly connected to the bottom of the transition area 5312, and one end of the second extension seal strip 552 is flush with the first extension seal strip 551, and the other end of the second extension seal strip 552 is flush with the transverse seal 512.

[0071] The first extended sealing strip 551 is integrally provided with the first longitudinal sealing member 523 , and the second extended sealing strip 552 is integrally provided with the transverse sealing member 512 . The first extended sealing strip 551 and the second extended sealing strip 552 may be integrally provided or may be sealed and fixedly connected.

[0072] In any top cover, the intersection sealing strip 55 also includes a third extended sealing strip 553 arranged at the end of the transverse sealing member 512 away from the first longitudinal sealing member 523, the third extended sealing strip 553 is sealed and fixedly connected to the end of the transverse sealing beam 511, and the third extended sealing strip 553 extends to below the first extended sealing strip 551 of the adjacent top cover.

[0073] Both ends of the first back beam 521 are provided with first notches engaged with the transverse sealing beam 511, and the protruding plate 5212 extends to the top of the transverse sealing beam 511 through the first notches, and when the top cover is in a closed state, the protruding plate 5212 is located below the connection box 53. The third extended sealing strip 553 is sealed and fixedly connected to the extended position of the protruding plate 5212, and the third extended sealing strip 553 forms a tilted shape matching the protruding plate 5212. In addition, the third extended sealing strip 553 is flush with the end of the protruding plate 5212.

[0074] A connecting plate 533 is provided on the top plate 12. When the top cover is in a closed state, the intersection seal 55 is sealed and pressed on the connecting plate 533 to play a role of sealing and water isolation. As an example, the connecting plate 533 is fixedly connected to the upper edge of the first part 1211 of the convex beam 121. The connecting plate 533 has a first side surface, a second side surface and a top surface. The bottom surface of the connecting plate 533 is fixedly connected to the upper edge of the first part 1211.

[0075] When the first top cover 21 is closed, the third extended sealing strip 553 is sealed and pressed against the first side surface of the connecting plate 533. When the second top cover 22 is closed, the first extended sealing strip 551 is sealed and pressed against the top surface of the connecting plate 533, and the second extended sealing strip 552 is sealed and pressed against the second side surface of the connecting plate 533. At the same time, the first extended sealing strip 551 is sealed and pressed against the ends of the protruding plate 5212 and the third extended sealing strip 553, thereby enhancing the waterproofness of both ends of the first top cover 21.

[0076] Therefore, the connecting box 53, the intersection seal 55 and the connecting plate 533 can seal the corner position between the first top cover 21 and the second top cover 22, so as to better seal the intersection position of the transverse part 51 and the longitudinal part 52, thereby ensuring the sealing and water-proofing effect of the top cover on the feed port 30.

[0077] The sealing structure also includes a water retaining structure arranged at the corner position of the top cover, and the water retaining structure plays a role in further water-proofing and sealing the gap between the top cover and the top plate and the gap between adjacent top covers.

[0078] The water retaining structure includes a first baffle plate 534 arranged between the second back beam 522 and the transverse seal 512. The first baffle plate 534 is fixedly connected to the bottom of the receiving plate 531. The first baffle plate 534 matches the width dimension of the second bending plate 5221 in the first direction, and the first baffle plate 534 is arranged on the side of the second bending plate 5221 facing the transverse seal 512. The first baffle plate 534 can seal and plug the gap between the transverse seal 512 and the second bending plate 5221, further enhancing the sealing and waterproof performance at the position of the connecting box 53, and making the sealing effect of the corner position of the first top cover 21 and the second top cover 22 better.

[0079] The water retaining structure also includes a second baffle 535 arranged on one side of the connection box 53 along the second direction. The second baffle 535 is arranged on the side of the receiving plate 531 away from the second back beam 522. The second baffle 535 is sealed and connected to the receiving plate 531. The shape of the upper edge of the second baffle 535 matches the shape of the receiving plate 531. The second baffle 535 has a second extension area 5351 extending above the transverse sealing beam 511 and a third extension area 5352 extending toward the top plate 12. The lower edge of the third extension area 5352 is flush with the lower edge of the transverse sealing beam 511. A second notch matching the transverse sealing beam 511 is formed between the second extension area 5351 and the third extension area 5352. When the second top cover 22 is pressed on the first top cover 21, the second baffle 535 can further retain water at the position of the connection box 53, and can reduce the amount of rainwater entering the sealing area of ​​the first top cover 21 and the second top cover 22.

[0080] The water retaining structure also includes a guide plate 536 connected to the second baffle plate 535 on the side away from the receiving plate 531. In the first direction, the two sides of the guide plate 536 are flush with the two sides of the receiving plate 531, so the guide plate 536 can block the second notch, and can prevent rainwater from directly entering the corner of the first top cover 21 and the second top cover 22 from the second notch. The guide plate 536 includes a connection area 5361 fixedly connected to the receiving plate 531, and a guide area 5362 integrally arranged with the connection area 5361. The guide area 5362 gradually tilts toward a side away from the receiving plate 531 along the direction from the receiving plate 531 to the top plate 12. The inclined guide area 5362 can guide rainwater, so that rainwater flows along the guide plate 536 to the side away from the receiving plate 531.

[0081] It should be noted that in order to avoid the locking structure 40, the inclination angle of the guide area 5362 in the guide plate 536 structure located on the side of the top cover locking structure 40 is set to be smaller, or the guide area 5362 can also be set to a vertical downward wall panel structure, so that the locking structure 40 can better press and fix the top cover.

[0082] In this embodiment, the transverse seal 512, the first longitudinal seal 523, the intersection seal 55, and the second longitudinal seal 542 can be sealing strips. The seals arranged on the same cover plate are integrally formed and can be sealed and connected to the plate on the cover plate by gluing.

[0083] It should be noted that the top cover in this embodiment is arranged above all sealing structures. The water accumulated on the top cover will flow to the top plate 12 due to the height difference, and a lot of rainwater will not accumulate on the top cover, thereby ensuring the sealing effect of the top cover on the feed port 30.

[0084] The locking structure 40 includes a pressure plate 42 which is rotatably connected to a locking rod 41 and fixedly connected to the locking rod 41, and quick lock structures 43 are provided at both ends of the locking rod 41 in the first direction. A handle structure can be connected to the locking rod 41. When the top cover is in the closed position, the locking rod 41 is rotated by the handle structure so that the pressure plate 42 is pressed against the upper edge of the top cover, and then the locking rod 41 is locked by the quick lock structure 43, thereby being able to play a role in fixing and limiting the top cover. When the top cover needs to be opened, the locking structure 40 is disengaged from the top cover, and the top cover can be opened normally. The locking structure 40 is correspondingly arranged on several top covers, and the opening and closing of multiple top covers can be controlled simultaneously by one locking rod 41. In this embodiment, the middle second top cover 22 does not need to be separately provided with a locking structure 40, which simplifies the locking structure 40 and makes the operation more convenient.

[0085] As an example, the top cover is pivotally connected to the top plate 12 via a hinge structure, and the top cover rotates along the hinge axis. Moreover, the locking structure 40 corresponds to the hinge structure one by one, so that the pressing force on the top cover is relatively uniform.

[0086] As an example, three top covers are provided in this embodiment, namely, the first top cover 21, the second top cover 22 and the third top cover 23. After the goods are loaded, the first top cover 21, the second top cover 22 and the third top cover 23 are closed in sequence, so that the second top cover 22 is pressed on the first top cover, and the third top cover 23 is pressed on the second top cover 22. The edge positions of the first top cover 21 and the second top cover 22 along the second direction are sealed and pressed with the top plate 12 on the top plate 12. Thus, the three top covers can seal and block the feed port 30, so that the container has a better sealing and waterproof effect.

[0087] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
