Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and fig. 2, the first embodiment of the present invention provides a container sealing structure, which includes a box body 10, a door 20 and a sealing assembly 30, wherein the door 20 is rotatably disposed on the box body 10, the sealing assembly 30 is disposed between the box body 10 and the door 20, and the sealing assembly 30 is capable of sealing a gap between the box body 10 and the door 20, so as to prevent the goods in the box body 10 from leaking. Wherein seal assembly 30 includes a first seal 31 and a second seal 32, first seal 31 being disposed between an end wall of door 20 and enclosure 10, and second seal 32 being disposed between a side wall of door 20 and enclosure 10. Specifically, at least one of the first seal 31 and the second seal 32 has a deformable cavity 33, and the cross section of the deformable cavity 33 is a closed structure.

By applying the container sealing structure provided by the embodiment, the first sealing element 31 and the second sealing element 32 are used as two sealing structures, so that the gap between the box body 10 and the box door 20 can be sealed for the second time, and the sealing performance of the container can be improved. Even if the first sealing structure contacted with the goods is invalid, the goods extrusion force received by the second sealing structure is far less than that of the first sealing structure, so that the goods can not be leaked. Moreover, the deformation cavity 33 is arranged, so that the first sealing element 31 and the second sealing element 32 are deformed, more gaps can be blocked by the first sealing element 31 and the second sealing element 32, and the sealing performance of the container can be further improved.

In the present embodiment, the cross section of the deformation chamber 33 is configured to be a sealed structure, which facilitates the deformation of the first sealing member 31 and the second sealing member 32, and on the other hand, the cargo will not leak through the deformation chamber 33 because the cross section of the deformation chamber 33 is configured to be a sealed structure. Wherein the cross section of the deformable cavity 33 refers to the cross section of the deformable cavity.

In this embodiment, the first sealing member 31 is disposed between the peripheral end wall of the door 20 and the cabinet 10, the first sealing member 31 is used for sealing the gap around the door 20, since the pressure at the bottom of the door 20 is large, the goods are easily leaked from the bottom of the door 20, the second sealing member 32 is disposed at the bottom of the door 20, and the second sealing member 32 is used for further assisting the sealing of the bottom of the door 20.

As shown in fig. 2, in the present embodiment, the cabinet 10 includes a door sill 11, and a space is provided between an inner wall of the door 20 and the door sill 11, and the second sealing member 32 is disposed in the space. Specifically, the inner wall of the door 20 is spaced from the threshold 11, which means that the inner wall of the door 20 is spaced from the threshold 11. After the door 20 is closed, the door 20 presses the second sealing member 32 disposed between the door sill 11 and the door 20, so that the second sealing member 32 is deformed, and the second sealing member 32 performs a good sealing function.

Wherein, the bottom wall of the cabinet 10 has a first inclined surface 12 at a position adjacent to the door 20, and a space is provided between an end of the first inclined surface 12 and an inner wall of the door 20, and the second sealing member 32 is disposed in the space. Through setting up first inclined plane 12, at the in-process of unloading, the first inclined plane 12 of goods accessible utilizes the effect of self gravity to unload down, is convenient for unload, can reduce operating personnel's working strength.

In the present embodiment, as shown in FIG. 2, the cross-sectional shape of the second seal 32 is trapezoidal (the deformable chamber is not shown). The top surface of the second sealing member 32 is a second inclined surface 321, and the first inclined surface 12 is coplanar with the second inclined surface 321. With the above-described structure, the lower portion of the door 20 can be sealed by the second sealing member 32, and since the top surface of the second sealing member 32 is also an inclined surface, the second sealing member 32 does not block the discharge of the goods.

In the present embodiment, the second sealer 32 is provided on the cabinet 10, and an end of the second sealer 32 abuts against an inner wall of the door 20.

The container sealing structure further comprises a rotating shaft, the rotating shaft penetrates through the container door 20 and is connected with the container body 10, the rotating shaft is horizontally arranged at the top of the container body 10, or the rotating shaft is vertically arranged on two sides of the container body 10, and the container door 20 can rotate relative to the container body 10 through the rotating shaft. In the present embodiment, the rotating shaft is horizontally disposed at the top of the box 10, and the box door 20 has an upturned structure.

In the present embodiment, the first seal 31 and the second seal 32 are joint strips. Wherein the deformation chamber 33 extends along the length of the bead, such that the deformation chamber 33 is deformed.

The first sealing element 31 and the second sealing element 32 can be fixed in a bonding or nail embedding mode, and the sealing device has the advantages of being simple in structure and convenient to assemble.

Adopt two joint strip cooperations to carry out the mode sealed, compare in the mode that sets up flexible cloth or rigidity and shelter from in box 10, do not have the problem that needs regularly change or block goods and unload.

When loading the bulk cargo, the lower portion of the door 20 is subject to a greater pressing force than other areas due to the weight of the cargo, and thus is easily leaked. At this time, due to the effect of the two sealing structures in the lower area of the box door 20, even if the first sealing structure contacted with the goods fails, the goods extrusion force received by the second sealing structure is far smaller than that of the first sealing structure, so that the goods cannot be leaked.

The first sealing structure and the second sealing structure are only used for easy understanding, and more than one sealing structure can be arranged according to actual conditions by utilizing the principle of multi-sealing. In fact, under the condition of more importance or severe limitation, two or more seals may be disposed around the door 20, and more sealing structures may be disposed at the bottom of the door 20, which is a relatively easy-to-leak area.

The position of the second seal 32 is not limited to the lower portion of the door 20. In the present embodiment, it is only one preferred embodiment to provide the second sealing member 32 at the lower portion of the door 20. In other embodiments, the second sealing element 32 may be disposed around the door 20, or disposed on both sides and the bottom of the door 20, and the disposition position thereof may be flexibly adjusted as long as it is ensured that the first sealing element 31 and the second sealing element 32 are disposed at the same time for double sealing.

The device is suitable for loading dry bulk goods in dry powder or fine particles, but is not limited to the device, and all similar structures or principles are within the protection scope of the application.
