The spatial relative position terms can be intended to include different orientations of the device in use or in operation in addition to the orientation shown in the drawing. For example, "upper", "lower", "left", "right", "horizontal", "vertical" in the present embodiment are the spatial relative position relationship of the container in the normal use state.

[0035] The terms first, second, third, fourth and the like in the present application are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated; in addition, it should be noted that, unless otherwise specified and limited, the term "connection" should be understood in a broad sense, for example, the connection can be direct connection or indirect connection through intermediate medium, can be fixed connection or movable connection or detachable connection or integral connection. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] In order for those skilled in the art to better understand the technical solutions in the present application, define the first direction as the length direction of the container, and the second direction as the width direction of the container. In the following, the specific embodiments of the present application will be described with reference to the accompanying drawings Figures 1-11The technical scheme in the embodiment of the utility model is clearly and completely described.

[0037] An embodiment of the utility model provides a container, the container in the embodiment can be an open top container, the box 10 is roughly cuboid structure. The container includes box 10, top cover. Box 10 can include the bottom plate, top plate 12, four side plates (only show the relevant structure of top plate 12 in the drawing) connected with each other, the bottom plate is parallel with top plate 12, and the side plate is perpendicular to the bottom plate and top plate 12, whereby the bottom plate, top plate 12 and four side plates enclose the box 10 structure.

[0038] Top plate 12 is provided with feed inlet 30, in the embodiment, only one feed inlet 30 is arranged on top plate 12, feed inlet 30 can be arranged as rectangle, the area of feed inlet 30 can be the area of top plate 12 after scaling, and granular goods such as bulk cargo such as silt can be filled into the container through feed inlet 30.

[0039] Top cover is pivotally connected to top plate 12, and the top cover is located on one side of the feed inlet 30, and the top cover rotates between the open position and the closed position. When the top cover is in the open position, the feed inlet 30 is in an open state, and the goods can be filled into the container from the feed inlet 30. When the top cover is in the closed position, the feed inlet 30 is in a closed state, and the top cover seals the feed inlet 30, preventing rainwater from entering the box 10 through the feed inlet 30.

[0040] The top cover is arranged along the length direction of the feed inlet 30 at least two, the pivot shafts of the at least two top covers are arranged along the first direction, and the pivot directions of all the top covers are the same. The top cover includes a cover plate body located in the middle and a frame structure arranged on the outer periphery of the cover plate body, and the frame structures of the adjacent two top covers are overlapped with each other, realizing the sealing between the adjacent two top covers, and the top cover is sealed and matched with the top plate through the frame structure, which simplifies the structure of the top cover and realizes better sealing effect.

[0041] Top plate 12 is provided with locking structure 40, locking structure 40 is arranged on one side of feed inlet 30, and locking structure 40 is matched with top cover structure, when the top cover is in the closed state, locking structure 40 can abut against the upper surface of the top cover, limiting and fixing the top cover, which can ensure that the top cover seals the feed inlet 30.

[0042] The cover plate body is provided with a plurality of upwardly recessed convex structures arranged at intervals along the first direction, so that the cross section of the cover plate body along the first direction is a plurality of continuous bending structures, forming a wave plate structure. In this way, the mechanical strength of the top cover is higher, and the top cover is not easy to deform under stress during transportation of the container, which can better seal and block the feed inlet 30.

[0043] The frame structure has a transverse portion 51 and a longitudinal portion 52. It is easy to understand that the transverse portion 51 extends along a first direction, and the longitudinal portion 52 extends along a second direction. Thus, the transverse portion 51 can seal and block the length direction of the top cover, and the longitudinal portion 52 can seal and block the width direction of the top cover, so that the sealing and blocking effect of the top cover on the feed port 30 is better.

[0044] Since the two adjacent top covers need to overlap each other to achieve sealing, the structures between the two adjacent top covers are not the same. As an example, in the present embodiment, two top covers are taken as an example for description. One of the top covers is a first top cover, and the other is a second top cover, and part of the structure of the second top cover is overlaid on part of the structure of the first top cover.

[0045] The first top cover includes a first cover body 21, the longitudinal portion 52 includes a first back beam 521 arranged at the edge position of the first cover body 21 and a second back beam 522 arranged at the edge position of the second cover body 22, the first back beam 521 and the second back beam 522 both extend along the first direction, and the second back beam 522 is overlaid on the first back beam 521. The bottom of the second back beam 522 is connected with a first longitudinal sealing member 523, and the first back beam 521 is warped towards the second back beam 522 on the side facing the second top cover. When the second top cover is overlaid on the first top cover, the warped part of the second back beam 522 can be sealingly matched with the first longitudinal sealing member 523. Thus, the sealing between the first top cover and the second top cover can be achieved.

[0046] The first back beam 521 includes a first bent plate 5211 and a protruding plate 5212 arranged integrally, the first bent plate 5211 is fixedly connected with the bottom wall of the first cover body 21, and the protruding plate 5212 is arranged on the side of the first bent plate 5211 close to the second top cover. The upper end edge of the protruding plate 5212 is higher than the first bent plate 5211, and the position where the protruding plate 5212 is flush with the first bent plate 5211 is fixedly connected with the side end of the first cover body 21, and the part of the protruding plate 5212 higher than the first bent plate 5211 is located above the first cover body 21. Thus, the first bent plate 5211 and the protruding plate 5212 form a groove structure with the opening upward, and the protruding plate 5212 is warped towards the second back beam 522.

[0047] It should be noted that the protruding structure in the first cover body 21 can form a water guide groove structure with the protruding plate 5212, which can guide the rainwater accumulated on the top cover and quickly drain the water.

[0048] The second top cover comprises a second cover plate body 22, which is integrally provided with an open downward mounting portion 221 at the edge position of the first top cover. The second back beam 522 comprises an integrally provided second bending plate 5221 and a mounting groove 5222. The second bending plate 5221 is fixedly connected with the bottom wall of the second cover plate body 22, and the mounting groove 5222 is arranged at the side of the second bending plate 5221 close to the first top cover. The mounting groove 5222 is matched with the mounting portion 221 in shape and size, and is fixedly connected with the bottom wall of the mounting portion 221. The first longitudinal seal 523 is sealingly connected to the bottom of the mounting groove 5222.

[0049] When the first top cover and the second top cover are closed, the first top cover is closed first, and then the second top cover is closed. The first longitudinal seal 523 at the bottom of the second top cover abuts against the upper end edge of the protruding plate 5212, so as to seal the gap between the first top cover and the second top cover, thereby blocking the rainwater.

[0050] The transverse portion 51 comprises a transverse sealing beam arranged at the edge position of the cover plate body and a transverse sealing member arranged in the transverse sealing beam. Due to the different positions of the transverse sealing beam and the transverse sealing member in the top cover, the corresponding structures are also different. The first top cover and the second top cover are still taken as examples for description. The transverse sealing beam comprises a first transverse sealing beam 511 arranged at the edge position of the first cover plate body 21 and a second transverse sealing beam 513 arranged at the edge position of the second cover plate body 22. The transverse sealing member comprises a first transverse sealing member 512 arranged in the first transverse sealing beam 511 and a second transverse sealing member 514 arranged in the second transverse sealing beam 513.

[0051] The first transverse sealing beam 511 and the second transverse sealing beam 513 are both arranged in a groove-shaped structure with an opening downward. The first transverse sealing member 512 is sealingly connected in the first transverse sealing beam 511, and the second transverse sealing member 514 is sealingly connected in the second transverse sealing beam 513.

[0052] As an example, only the first transverse sealing beam 511 and the first transverse sealing member 512 are taken as examples for description, and the same parts in the structures of the second transverse sealing beam 513 and the second transverse sealing member 514 will not be described herein. The first transverse sealing beam 511 comprises a mounting plate 5111, an edge plate 5112 and a fixed plate 5113, which are integrally formed. The fixed plate 5113 is fixedly connected with the first top cover 21, and can also be integrally connected.

[0053] The mounting plate 5111 is horizontally arranged, the edge plate 5112 and the fixing plate 5113 are arranged on both sides of the edge plate 5112 in the first direction respectively, 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 downwardly open containing groove, and the first transverse sealing member 512 is sealingly fixed to the bottom of the mounting plate 5111.

[0054] The lower end of the edge plate 5112 extends downwardly below the first transverse sealing member 512, and the first transverse sealing beam 511 can protect the first transverse sealing member 512 and avoid direct contact of rainwater with the first transverse sealing member 512 as much as possible, thereby ensuring the service life of the first transverse sealing member 512.

[0055] The top of the top plate 12 is provided with a convex beam 121 along the edge of the feeding port 30, the convex beam 121 includes two first parts 1211 extending in the first direction and two second parts 1212 extending in the second direction, and the two first parts 1211 and the two second parts 1212 enclose a frame-shaped convex structure matching the shape and size of the feeding port 30.

[0056] The first top cover 21 and the second top cover 22 are both provided with the transverse part 51 on the opposite sides in the first direction, when the first top cover 21 and the second top cover 22 are closed, the first transverse sealing beam 511 and the second transverse sealing beam 513 can be matched with the second part 1212, and the first transverse sealing member 512 and the second transverse sealing member 514 are pressed to the upper end edge of the first part 1211 to realize transverse sealing.

[0057] In the specific implementation process, if N top covers are arranged, the edge positions of the first top cover and the Nth top cover are provided with the edge sealing part 54 matched with the second part 1212 of the convex beam 121. If only two top covers are arranged, such as the first top cover and the second top cover, the edge of the first top cover away from the second top cover and the edge of the second top cover away from the first top cover are provided with the edge sealing part 54.

[0058] The edge sealing part 54 includes a third sealing beam 541 fixedly connected with the edge position of the top cover and a second longitudinal sealing member 542 sealingly connected to the bottom of the third sealing beam 541. The third sealing beam 541 is matched with the second part 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 sealingly pressed against the upper end edge of the second part 1212 to realize longitudinal sealing of the edge position.

[0059] In an optional embodiment, the top cover further comprises a connecting portion 53 arranged at the corner of the cover plate body, the connecting portion 23 is used to connect the transverse portion 51 and the longitudinal portion 52, and when the top cover is in the closed position, the connecting portion 53 of a top cover is sealingly overlapped on the connecting portion 53 of the adjacent next top cover, and the connecting portion 53 can also sealingly fit with the convex beam 121 on the top plate 12. The sealing performance between the top covers overlapped with each other is better, and the sealing waterproof performance between the top cover and the top plate 12 is also better.

[0060] As an example, the connecting portion 53 comprises a receiving plate 531 arranged at the corner of the cover plate body, a receiving seal 532 arranged below the receiving plate 531, and a connecting plate 533 arranged on the convex beam 121. Taking the first top cover and the second top cover described above as an example, the receiving plate 531 is fixedly connected between the second back beam 522 and the second transverse sealing beam 513, the receiving seal 532 is fixedly connected between the first longitudinal sealing member 523 and the second transverse sealing member 514, and the receiving seal 532 is integrally connected with the first longitudinal sealing member 523 and the second transverse sealing member 514.

[0061] The receiving plate 531 has a receiving area 5311 fixedly connected with the second back beam 522 and a first extension area 5312 fixedly connected with the second transverse sealing beam 513, and the receiving area 5311 and the first extension area 5312 are integrally arranged. The height of the receiving area 5311 is flush with the height of the second back beam 522, and the shape of the receiving area 5311 towards the edge position of the first top cover 21 matches the shape of the first mounting groove 5222. The first extension area 5312 gradually inclines downward from the receiving area 5311 towards the second transverse sealing beam 513, one end of the first extension area 5312 is connected with the receiving area 5311, and the other end is connected with the second transverse sealing beam 513, forming a height difference, so that the first extension area 5312 can be connected with the end of the second transverse sealing beam 513.

[0062] The shape of the receiving seal 532 matches the shape of the receiving plate 531, so that the first longitudinal sealing member 523, the receiving seal 532, and the second transverse sealing member 514 can be sealingly fitted with the edge structure of the second top cover 22, and the edge position where the second top cover 22 is connected with the feed inlet 30 has a better sealing effect.

[0063] The connecting plate 533 is fixedly connected to the upper edge of the second portion 1212 of the convex beam 121, and the connecting plate 533 has a first side surface matched with the first transverse sealing member 512, a second side surface matched with the receiving seal 532, and a top surface. The bottom surface of the connecting plate 533 is fixedly connected with the upper edge of the second portion 1212.

[0064] The first transverse sealing member 512 has an extension 5121 extending to the outside of the first transverse sealing beam 511, and the extension 5121 is sealingly connected with the extension position of the protruding plate 5212, so that the extension 5121 forms a raised shape matched with the protruding plate 5212.

[0065] When the first top cover 21 is in the closed state, the extension 5121 is in pressure contact with the first side of the connecting plate 533. When the second top cover 22 is in the closed state, the receiving sealing member 532 is in pressure contact with the second side and the top surface of the connecting plate 533. Therefore, the connecting portion 53 can seal and block the corner position between the first top cover 21 and the second top cover 22, and the transverse portion 51, the longitudinal portion 52 and the connecting portion 53 can better seal the feeding port 30. When the first top cover 21 is closed, the end of the protruding plate 5212 is embedded in the receiving sealing member 532, thereby enhancing the waterproofness of the two ends of the first top cover 21.

[0066] In the embodiment, the first transverse sealing member 512, the second transverse sealing member 514, the first longitudinal sealing member 523, the receiving sealing member 532 and the second longitudinal sealing member 542 can be sealing rubber strips. The sealing members provided on the same cover plate are integrally formed, and the sealing members can be sealingly connected with the plate members on the cover plate by means of gluing.

[0067] It should be noted that in the embodiment, the top cover is arranged above all frame structures, and water accumulated on the top cover will flow to the top plate 12 due to the height difference, so that more rainwater will not be accumulated on the top cover, thereby ensuring the sealing effect of the top cover on the feeding port 30.

[0068] In the embodiment, the locking structure 40 includes a lock rod 41 rotatably connected to the top plate 12, a pressing plate 42 fixedly connected to the lock rod 41, and quick locking structures 43 arranged at the two ends of the lock rod 41 in the first direction. The lock rod 41 can be connected with a handle structure, and when the top cover is in the closed position, the handle structure is used to rotate the lock rod 41 to press the pressing plate 42 against the upper edge of the top cover, and then the quick locking structures 43 are used to lock the lock rod 41, so that the top cover can be fixed and limited. When the top cover needs to be opened, the locking structure 40 is separated from the top cover, and the top cover can be normally opened. The locking structure 40 is correspondingly arranged on several top covers, and a plurality of top covers can be simultaneously controlled by one lock rod 41. In the embodiment, the second top cover 22 in the middle does not need to be separately provided with a locking structure 40, thereby simplifying the locking structure 40 and making the operation more convenient.

[0069] For example, the top cover is pivotally connected to the top plate 12 by a hinge structure, and the top cover rotates along the hinge shaft. The locking structure 40 corresponds to the hinge structure, so that the pressing force applied to the top cover is more uniform.

[0070] As an example, three top covers are provided in the embodiment, and the three top covers are respectively a first top cover, a second top cover and a third top cover. After the goods are filled, the first top cover, the second top cover and the third top cover are closed in sequence, so that the second top cover is pressed on the first top cover, and the third top cover is pressed on the second top cover. The edge positions of the first top cover and the third top cover along the second direction are sealingly pressed on the convex beams 121 on the top plate 12. Therefore, the three top covers can play a sealing plugging role on the feeding port 30, so that the container has a better sealing and waterproof effect.

[0071] The above describes the structure, characteristics and effect of the present application according to the embodiments shown in the drawings, and the above is only a preferred embodiment of the present application, but the present application is not limited to the embodiments shown in the drawings, any change or modification made according to the concept of the present application, or equivalent embodiments with equivalent changes, as long as they are within the scope of the present application.
