Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to a container. Background Technology

[0002] Containers, such as bulk cargo containers, are special containers used for loading and transporting powdery or granular goods. To facilitate loading and unloading, existing containers are known to have loading ports on the top of the container and unloading ports on the sides, allowing the container to be tilted at a certain angle for unloading when the unloading ports are open.

[0003] Currently, for bulk cargo containers, to ensure sealing and prevent leakage of powdery or granular cargo, unloading ports are typically equipped with sealing rings and clamping locks. Specifically, the sealing ring is often placed in the gap between the door and the door frame, and is compressed and sealed by the clamping force between the door panel and the bottom beam after the door is locked. However, when the powdery cargo is full, it generates external expansion force. When the external expansion force is perpendicular to the sealing surface of the sealing ring, the sealing ring is prone to deformation due to stress concentration. When the external expansion force is parallel to the sealing surface of the sealing ring, the pressure of the external expansion force on the door, or the influence of production process, manufacturing, and assembly errors, makes it impossible for the door panel and the bottom beam to be completely flat. This results in inconsistent sealing tightness of the sealing ring, creating vibration gaps during continuous transportation, which in turn leads to powder leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a container in which the stress on the outer periphery of the unloading port is dispersed and the sealing effect is better.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] According to one aspect of this application, a container is provided, comprising:

[0007] A container body, the interior of which is used to hold goods; the container body is provided with a discharge port communicating with its interior;

[0008] A door body, which is rotatably connected to the housing, is capable of rotating relative to the housing to open and close the discharge port;

[0009] At least two sealing assemblies are arranged around the outer periphery of the discharge port in a direction away from the discharge port; each sealing assembly includes a sealing groove and a sealing element, one of which is provided on the housing and the other is provided on the door. The sealing groove opens to the side facing the sealing element, and the opening direction of the sealing groove is parallel to the axial direction of the discharge port. The sealing element can protrude into the sealing groove and be sealed to the sealing groove, so that all the sealing elements and all the sealing grooves together form a serpentine pressure-reducing rotary channel.

[0010] In some embodiments, at least one of the sealing components has a sealing ring within the sealing groove, and the sealing member is used to abut against and compress the sealing ring so that the sealing ring covers at least a portion of the outer periphery of the sealing member near the sealing groove.

[0011] In some embodiments, the sealing ring is provided in the sealing groove of each sealing assembly, and the compression distance of the sealing element of each sealing assembly that compresses the sealing ring is not equal.

[0012] In some embodiments, the cross-sectional area of ​​the shape enclosed by the outer peripheral wall of the sealing ring is larger than the cross-sectional area of ​​the shape enclosed by the outer peripheral wall of the corresponding sealing element, and the cross-sectional area of ​​the shape enclosed by the inner peripheral wall of the sealing ring is smaller than the cross-sectional area of ​​the shape enclosed by the inner peripheral wall of the corresponding sealing element.

[0013] In some embodiments, the seal abuts against the central region of the corresponding sealing ring.

[0014] In some embodiments, the sealing ring is made of a flexible material;

[0015] The sealing ring is made of rubber.

[0016] In some embodiments, all of the sealing assemblies include at least one first sealing assembly and at least one second sealing assembly;

[0017] The sealing groove of the first sealing assembly is provided on the housing, and the sealing element of the first sealing assembly is provided on the door; the sealing element of the second sealing assembly is provided on the housing, and the sealing groove of the second sealing assembly is provided on the door.

[0018] In some embodiments, the seal is welded to the housing or the door.

[0019] The seal is made of a rigid material.

[0020] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0021] In this application, the outer circumference of the unloading port is provided with at least two sealing components, each including a sealing groove and a sealing element. One of the sealing groove and the sealing element is located on the housing, and the other on the door. Since the sealing groove opens towards the sealing element, the sealing element can protrude into the sealing groove and form a sealing connection. Because the opening direction of the sealing groove is parallel to the axial direction of the unloading port, that is, the opening direction of the sealing groove is the same as the direction of the external expansion force of the goods inside the housing, this design allows all the sealing elements and all the sealing grooves to form a serpentine pressure-reducing rotary channel, which can handle a single... The design decomposes the external expansion force of the goods inside the container in multiple directions, avoiding stress concentration at the sealing components. Furthermore, the above design constitutes at least two levels of sealing connection between the door and the container. At the same time, because the seal protrudes into the sealing groove by a certain distance, a sealing margin is left between the door and the container. This margin can be used to offset the displacement caused by the continuous vibration during transportation, which leads to the movement of the door relative to the container, as well as errors caused by the production process, manufacturing, and assembly. This maintains a good sealing connection between the door and the container, thereby reducing the possibility of cargo leakage and improving the sealing effect between the container and the door.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] This application provides a container for storing goods to facilitate their storage and transportation. The goods may be in the form of powder or similar substances.

[0034] The following detailed description of specific embodiments of the container of this application is provided in conjunction with the accompanying drawings.

[0035] Figure 1 This is a three-dimensional structural diagram of the container in this embodiment. Figure 2 This is one of the partial cross-sectional views of the container in this embodiment. Figure 3 This is another partial sectional view of the container in this embodiment. Figure 4 for Figure 3 Enlarged structural diagram at point A in the middle.

[0036] refer to Figures 1 to 4The container includes a container body 1, a door 2, and at least two sealing assemblies 3. The interior of the container body 1 is used to hold goods, and the container body 1 has a discharge port 11 communicating with its interior. The door 2 is rotatably connected to the container body 1 and can rotate relative to the container body 1 to open and close the discharge port 11. At least two sealing assemblies 3 are arranged around the outer periphery of the discharge port 11 in a direction away from the discharge port 11. Each sealing assembly 3 includes a sealing groove 31 and a sealing element 32. One of the sealing groove 31 and the sealing element 32 is located on the container body 1, and the other is located on the door 2. The sealing groove 31 opens towards the side facing the sealing element 32, and the opening direction of the sealing groove 31 is parallel to the axial direction of the discharge port 11. The sealing element 32 can protrude into the sealing groove 31 and be sealed to the sealing groove 31, so that all the sealing elements 32 and all the sealing grooves 31 together form a serpentine pressure-reducing rotary channel.

[0037] In this application, at least two sealing components 3 are provided around the outer periphery of the discharge port 11. Each sealing component 3 includes a sealing groove 31 and a sealing element 32. One of the sealing groove 31 and the sealing element 32 is located on the housing 1, and the other is located on the door 2. Since the sealing groove 31 opens towards the sealing element 32, the sealing element 32 can protrude into the sealing groove 31 and form a sealing connection. Because the opening direction of the sealing groove 31 is parallel to the axial direction of the discharge port 11, that is, the opening direction of the sealing groove 31 is the same as the direction of the outward expansion force of the goods inside the housing 1, this design allows all the sealing elements 32 and all the sealing grooves 31 to form a serpentine pressure-reducing rotary channel, which can effectively reduce pressure on a single... The external expansion force of the goods inside the box 1 in one direction is decomposed in multiple directions to avoid stress concentration at the sealing component 3. Furthermore, the above design ensures that all the seals 32 and all the sealing grooves 31 cooperate to form at least two levels of sealing connection between the door 2 and the box 1. At the same time, since the seals 32 protrude into the sealing grooves 31 by a certain distance, there is a sealing margin between the door 2 and the box, which can be used to offset the displacement caused by the movement of the door 2 relative to the box 1 due to continuous vibration during transportation and the errors caused by the production process, manufacturing, and assembly. This maintains a good sealing connection between the door 2 and the box 1, thereby reducing the possibility of cargo leakage and improving the sealing effect between the box 1 and the door 2.

[0038] In this embodiment, the interior of the container 1 is hollow and used to hold goods. For ease of description, the interior space facing the container 1 is referred to as the inside, and the space facing away from it as the outside.

[0039] Specifically, box 1 is rectangular in shape.

[0040] The housing 1 is provided with a feed inlet. Specifically, the feed inlet may be located on the top of the housing 1. Optionally, a cover is provided at the feed inlet, and the cover is connected to the housing 1 (e.g., rotatable connection, detachable connection, sliding connection, etc.), and the cover is used to open and close the feed inlet.

[0041] The container 1 is provided with a discharge port 11 that communicates with its interior. The discharge port 11 is used for the passage of goods inside the container 1 to realize the unloading operation. Specifically, the discharge port 11 is located at the lower part of the side wall of the container 1, which facilitates the outflow of goods inside the container 1 and reduces the amount of goods left behind.

[0042] The door 2 is rotatably mounted on the box 1, and the door 2 can rotate relative to the box 1 to open and close the unloading port 11. For example, the box 1 is provided with a hinge seat, which is spaced apart from the unloading port 11. The hinge shaft passes through the first end of the door 2 and the hinge seat to realize the rotatable connection between the door 2 and the box 1.

[0043] Optionally, the second end of the door 2 is detachably connected to the housing 1. This design facilitates applying a clamping force to the door 2 so that it remains clamped and closed at the discharge port 11. Alternatively, it also facilitates disconnecting the connection between the second end of the door 2 and the housing 1, thereby opening the door 2 and opening the discharge port 11. The second end of the door 2 is opposite to the first end.

[0044] It should be noted that the detachable connection mentioned here can be any method in the art, and this application does not make any improvement to it, nor does it impose any restrictions.

[0045] In this embodiment, at least two sealing components 3 are arranged around the outer periphery of the discharge port 11 in a direction away from the discharge port 11. That is, each sealing component 3 is annular. Exemplarily, all sealing components 3 include a first sealing component 3a, a second sealing component 3b, a third sealing component, and so on. Among them, the first sealing component 3a is arranged around the outer periphery of the discharge port 11 in the circumferential direction, the second sealing component 3b is arranged around the outer periphery of the first sealing component 3a in the circumferential direction, the third sealing component is arranged around the outer periphery of the second sealing component 3b in the circumferential direction, and so on.

[0046] Each sealing component 3 includes a sealing groove 31 and a sealing element 32, one of which is located on the housing 1 and the other on the door 2. Both the sealing groove 31 and the sealing element 32 are annular.

[0047] For example, all sealing components 3 include at least one first sealing component 3a and at least one second sealing component 3b. The sealing groove 31 of the first sealing component 3a is disposed on the housing 1, and the sealing element 32 of the first sealing component 3a is disposed on the door 2. The sealing element 32 of the second sealing component 3b is disposed on the housing 1, and the sealing groove 31 of the second sealing component 3b is disposed on the door 2.

[0048] In other embodiments, the sealing element 32 of the first sealing assembly 3a is disposed on the housing 1, and the sealing groove 31 of the first sealing assembly 3a is disposed on the door 2. The sealing groove 31 of the second sealing assembly 3b is disposed on the housing 1, and the sealing element 32 of the second sealing assembly 3b is disposed on the door 2.

[0049] Figure 5 This is a schematic diagram of the arrangement of the sealing component 3 in some embodiments.

[0050] refer to Figure 5 In some embodiments, the sealing grooves 31 of all sealing components 3 are provided on the housing 1, and the sealing elements 32 of all sealing components 3 are provided on the door 2.

[0051] Figure 6 This is a schematic diagram of the arrangement of the sealing component 3 in other embodiments.

[0052] refer to Figure 6 In other embodiments, the sealing grooves 31 of all sealing components 3 are provided on the door body 2, and the sealing elements 32 of all sealing components 3 are provided on the box body 1.

[0053] refer to Figures 1 to 4 In this embodiment, the sealing groove 31 opens towards the side of the sealing member 32, and the opening direction of the sealing groove 31 is parallel to the axial direction of the unloading port 11. Since the goods inside the box 1 exert an outward pressure on the door 2 when the door 2 is closed at the unloading port 11, the above design makes the opening direction of the sealing groove 31 parallel to the direction of the main pressure P (i.e., the outward expansion force of the goods inside the box) generated by the goods on the door 2 when it is closed.

[0054] The seal 32 is welded and fixed to the housing 1 or the door 2. The seal 32 can protrude into the sealing groove 31 and be sealed to the sealing groove 31, so that all the seals 32 and all the sealing grooves 31 together form a serpentine pressure-reducing rotary channel.

[0055] Specifically, with Figure 3 and Figure 4 Taking the direction shown as an example, the main pressure (external expansion force) P exerted by the goods inside the box 1 on the closed door 2 is from top to bottom. Since the opening direction of each sealing groove 31 is parallel to the direction of the external expansion force of the goods, after each sealing element 32 protrudes into the corresponding sealing groove 31 and is sealed and connected to the sealing groove 31, the material discharge channel at the joint between the door 2 and the box 1 changes from the straight line type in the prior art to sequentially upward-left-down-left-upward, which constitutes a serpentine pressure reduction and rotation channel. This decomposes the original single-direction external expansion force P into multiple directions, avoiding stress concentration that causes deformation of the sealing component 3 or movement of the door 2 relative to the box 1, thereby generating a material discharge gap, reducing the possibility of goods leakage, and improving the sealing effect between the box 1 and the door 2.

[0056] Or, with Figure 5 Taking the direction shown as an example, after each seal 32 protrudes into the corresponding sealing groove 31 and is sealed and connected to the sealing groove 31, the material discharge channel at the joint between the door body 2 and the box body 1 changes from the straight type in the prior art to upward-left-downward-leftward-upward-leftward-downward, so as to form a serpentine pressure reduction rotary channel.

[0057] Or, with Figure 6 Taking the direction shown as an example, after each seal 32 protrudes into the corresponding sealing groove 31 and is sealed and connected to the sealing groove 31, the material discharge channel at the joint between the door body 2 and the box body 1 changes from the straight type in the prior art to downward-left-upward-leftward-downward-leftward-upward, so as to form a serpentine pressure reduction rotary channel.

[0058] exist Figures 1 to 4 In the embodiment shown, Figure 5 Some embodiments shown and Figure 6 In some other embodiments shown, at least one sealing component 3 has a sealing ring 4 in its sealing groove 31. The sealing member 32 is used to abut against and compress the sealing ring 4 so that the sealing ring 4 covers at least a portion of the outer periphery of the sealing member 32 near the sealing groove 31. That is, this design allows the sealing member 32 to protrude into the sealing ring 4 by a certain distance, thereby achieving a sealing connection between the sealing member 32 and the sealing groove 31 of each sealing component 3, and leaving a sealing allowance. This can be used to offset the vibration gap caused by continuous vibration during transportation and the errors caused by production process, manufacturing, and assembly, maintain a good sealing connection between the door 2 and the box 1, thereby reducing the possibility of cargo leakage and improving the sealing effect between the box 1 and the door 2.

[0059] The compression distance D of the sealing ring 4 caused by the sealing element 32 is in the range of 0mm to 10mm.

[0060] Optionally, each sealing component 3 has a sealing ring 4 in its sealing groove 31. The sealing elements 32 of each sealing component 3 compress the sealing ring 4 by different distances. This design makes the resistance brought by each sealing ring 4 smaller during the process of the door 2 rotating relative to the box 1 to close, thus improving the smoothness of the rotation of the door 2.

[0061] For example, for ease of description, the sealing groove 31 of the first sealing component 3a is referred to as the first sealing groove, the sealing element 32 of the first sealing component 3a is referred to as the first sealing element, and the sealing ring 4 disposed in the first sealing groove is referred to as the first sealing ring. Similarly, the sealing groove 31 of the second sealing component 3b is referred to as the second sealing groove, the sealing element 32 of the second sealing component 3b is referred to as the second sealing element, and the sealing ring 4 disposed in the second sealing groove is referred to as the second sealing ring. Specifically, the compression distance by which the first sealing element compresses the first sealing ring is less than the compression distance by which the second sealing element compresses the second sealing ring. This design ensures that during the process of the door 2 rotating relative to the housing 1 to close, the second seal will first contact the second sealing ring. At this time, there is a gap between the first seal and the first sealing ring. As the door 2 continues to rotate, the second seal gradually compresses the second sealing ring, and the first seal contacts the first sealing ring and begins to compress it. In other words, the above design ensures that there is a gap between the contact time point T1 of the second seal and the second sealing ring and the contact time point T2 of the first seal and the first sealing ring. During the time period from T1 to T2, the resistance encountered by the door 2 during rotation comes only from the second sealing ring. Compared to the situation where the first seal also contacts the first sealing ring at the same time as the second seal and the second sealing ring, the above design can better reduce the resistance during the closing and rotation process of the door 2.

[0062] Of course, in other embodiments, the compression distance by which the first seal compresses the first sealing ring may be greater than or equal to the compression distance by which the second seal compresses the second sealing ring.

[0063] In this design, the cross-sectional area of ​​the shape enclosed by the outer peripheral wall of the sealing ring 4 is larger than the cross-sectional area of ​​the shape enclosed by the outer peripheral wall of the corresponding sealing element 32, and the cross-sectional area of ​​the shape enclosed by the inner peripheral wall of the sealing ring 4 is smaller than the cross-sectional area of ​​the shape enclosed by the inner peripheral wall of the corresponding sealing element 32. This design ensures that when the door 2 is closed at the discharge port 11, even if there is continuous vibration causing relative movement between the door 2 and the box 1, or if there are errors caused by the production process, manufacturing, or assembly, the sealing element 32 can accurately abut against the corresponding sealing ring 4 in the circumferential direction, thereby improving the alignment accuracy and sealing effect.

[0064] Specifically, the sealing element 32 abuts against the central region of the corresponding sealing ring 4. This central region refers to the area between the inner and outer peripheral walls of the sealing ring 4, allowing the door 2 to close at the discharge port 11. After the sealing element 32 abuts against the corresponding sealing ring 4, there is a gap between the outer peripheral wall of the sealing element 32 and the outer peripheral wall of the sealing ring 4, and a gap between the inner peripheral wall of the sealing element 32 and the inner peripheral wall of the sealing ring 4. This design causes the sealing element 32 to deform due to compression against the central region of the sealing ring 4. The portions of the sealing ring 4 located on opposite sides of the sealing element 32 can then cover and adhere to the inner and outer peripheral walls of the sealing element 32 under the action of deformation. That is, the cross-section of the contact surface between the sealing ring 4 and the sealing element 32 is approximately "U"-shaped. Compared to a sealing method where two planes directly abut and adhere, this design allows the sealing element 32 and the sealing ring 4 to maintain a seal between the door 2 and the housing 1. Even under conditions where continuous vibration causes relative movement between the seal 32 and the sealing ring 4, or errors arise due to production processes, manufacturing, or assembly, each seal 32 can maintain its state of abutting and compressing the corresponding sealing ring 4, thus maintaining a good sealing connection between the door 2 and the box 1. Furthermore, the above design allows all the seals 32 and all the sealing rings 4 to cooperate in forming a serpentine sealing rotary channel. Compared to the sealing method where two planes directly abut and fit together, the serpentine sealing rotary channel can decompose the external expansion force P of the goods inside the box 1 in multiple directions, avoiding stress concentration that could cause deformation of the sealing component 3 or movement of the door 2 relative to the box 1, thereby reducing the possibility of goods leakage and improving the sealing effect between the box 1 and the door 2.

[0065] Among them, the sealing ring 4 is made of flexible material, which makes the sealing ring 4 have a certain elasticity, and can deform. It can be compressed when subjected to external force, or return to its original shape when not subjected to external force.

[0066] Specifically, the sealing ring 4 can be made of rubber. For example, the sealing ring 4 can be made of materials such as EPDM (ethylene propylene diene monomer rubber).

[0067] In this embodiment, the sealing element 32 is made of a rigid material, giving it good rigidity. This allows the sealing element 32 to abut against and compress the sealing ring 4, which is made of a flexible material, under the clamping force of the door body 2, causing the sealing ring 4 to deform inward. For example, the sealing element 32 can be made of steel.

[0068] In some modified embodiments, all sealing components 3 include a first sealing component and at least one second sealing component, wherein the first sealing component is located between the inner circumferential side of the second sealing component and the outer circumference of the discharge port 11. A sealing ring 4 is provided in the sealing groove 31 of one of the first and second sealing components, while the sealing ring 4 is omitted in the sealing groove 31 of the other.

[0069] Taking the arrangement of the sealing groove 31 of the first sealing component having a sealing ring 4 and the sealing groove 31 of the second sealing component omitting the sealing ring 4 as an example, when the door 2 is in the closed state, the sealing member 32 of the first sealing component abuts against and compresses the sealing ring 4 in the sealing groove 31, and the sealing member 32 of the second sealing component protrudes into the sealing groove 31 and abuts against the side wall of the sealing groove 31 away from the opening side.

[0070] At this time, the sealing element 32 of the first sealing assembly is made of a rigid material. The sealing element 32 of the second sealing assembly can be made of either a rigid or a flexible material. When the door 2 is in the closed state, the sealing element 32 of the second sealing assembly, made of a flexible material, abuts against the side wall of the sealing groove 31 away from the opening and undergoes compression deformation, leaving a sealing allowance. Alternatively, the sealing element 32 of the second sealing assembly is made of a rigid material, and a sealing gasket made of a flexible material is provided at the end of the sealing element 32 facing the sealing groove 31. When the door 2 is in the closed state, the sealing gasket abuts against the side wall of the sealing groove 31 away from the opening and undergoes compression deformation, leaving a sealing allowance.

[0071] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0072] In this application, the outer circumference of the unloading port is provided with at least two sealing components, each including a sealing groove and a sealing element. One of the sealing groove and the sealing element is located on the housing, and the other on the door. Furthermore, since the sealing groove opens towards the sealing element, the sealing element can protrude into the sealing groove and form a sealing connection. Also, because the opening direction of the sealing groove is parallel to the axial direction of the unloading port, that is, the opening direction of the sealing groove is the same as the direction of the external expansion force of the goods inside the housing, this design allows all the sealing elements and all the sealing grooves to together form a serpentine pressure-reducing rotary channel. This design can decompose the external expansion force of goods inside the container from one direction into multiple directions, avoiding stress concentration at the sealing components. Furthermore, the above design constitutes at least two levels of sealing connection between the door and the container. At the same time, the sealing element and sealing groove have a sealing margin between the door and the container, which can be used to offset the displacement caused by the movement of the door relative to the container due to continuous vibration during transportation, as well as the errors caused by the production process, manufacturing, and assembly. This maintains a good sealing connection between the door and the container, thereby reducing the possibility of cargo leakage and improving the sealing effect between the container and the door.

Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
