Cover plate assembly and container

Abstract

The invention provides a cover plate assembly and a container. The cover plate assembly comprises a cover plate, an adjusting piece, a first locking rod and a pressing piece. The cover plate is used for being connected to a container body of the container and used for covering a discharging opening of the container body of the container in an openable mode. The adjusting part is connected to the cover plate, and the position of the adjusting part in the thickness direction of the cover plate is adjustable; the first lock rod is used for being rotatably arranged on a container body of the container. One end of the pressing piece is fixedly connected to the peripheral face of the first locking rod, and the other end of the pressing piece is located on the outer side of the first locking rod and used for acting on the cover plate or protruding out of the adjusting piece on the outer side of the cover plate, so that the cover plate covering the discharging opening of the box body is tightly pressed on the box body. Therefore, when the locked cover plate covering the discharging opening cannot seal and cover the discharging opening, the position of the adjusting piece is adjusted, and therefore the length of the protruding part of the adjusting piece is increased; in this way, under the condition that the cover plate covering the discharging opening is locked, the cover plate can seal and cover the discharging opening.

Description

Technical Field

[0001] This application relates to the field of containers, and more specifically to containers with cover plate components. Background Technology

[0002] Containers, as a common international multimodal transport tool, have long been widely used globally. In the bulk transport of powder materials, to ensure sealing, a small unloading port is provided at the end of the container body for unloading the powder. A cover plate is installed outside the unloading port. One end of the cover plate has a hinge for rotatably connecting to the container body. The other end of the cover plate has a locking mechanism for locking the cover plate closed over the unloading port. A sealing strip is installed inside the cover plate. When the cover plate is closed over the unloading port, locking the cover plate through the locking mechanism presses the sealing strip against the container body, thereby sealing the gap between the cover plate and the container body, thus achieving the required seal.

[0003] Sealing strips are generally made of rubber, and after repeated compression and prolonged use, they age. Thus, when the cover plate is closed over the discharge port and the cover plate is locked by the locking mechanism, the aged sealing strip has reduced compression, and may even fail to seal the gap between the cover plate and the housing.

[0004] Therefore, this application provides a cover assembly and a container to at least partially solve the above-mentioned problems. Summary of the Invention

[0005] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed embodiments section. This summary section is not intended to limit the key features and essential technical features of the claimed technical solutions, nor is it intended to determine the scope of protection of the claimed technical solutions.

[0007] According to the cover plate assembly of this application, when the locked cover plate of the discharge port cannot seal the discharge port, the position of the adjusting member is adjusted to increase the length of the protruding part of the adjusting member; thus, when the cover plate of the discharge port is locked, the cover plate can seal the discharge port; by adjusting the position of the adjusting member, thereby adjusting the length of the protruding part of the adjusting member, the pressure of the cover plate on the box body when the cover plate of the discharge port is locked can be adjusted, thereby adjusting the sealing performance of the cover plate covering the discharge port.

[0008] Optionally, the adjusting element is threadedly connected to the cover plate.

[0009] Optionally, the cover plate includes: The cover body is used to connect to the housing; A support member is connected to the cover plate body. The support member includes a pressure plate portion located on the outside of the cover plate body and spaced apart from the outer surface of the cover plate body. The adjusting member passes through the pressure plate portion, and the pressure member is used to act on the pressure plate portion or extend outward to the outside of the adjusting member.

[0010] Optionally, the support member also includes a connecting plate portion whose plane intersects with the plane of the pressure plate portion, one end of the connecting plate portion being connected to the pressure plate portion, and the other end of the connecting plate portion being used to connect to the outer side of the cover plate body.

[0014] This application also provides a container, the container comprising: The container has a discharge port; and The aforementioned cover plate assembly.

[0015] According to the container of this application, the container includes the aforementioned cover assembly. When the locked cover of the unloading port cannot seal the unloading port, the position of the adjusting member is adjusted to increase the length of the protruding part of the adjusting member. In this way, when the cover of the unloading port is locked, the cover can seal the unloading port. By adjusting the position of the adjusting member, thereby adjusting the length of the protruding part of the adjusting member, the pressure of the cover on the container body when the cover of the unloading port is locked can be adjusted, thereby adjusting the sealing performance of the cover when the unloading port is sealed.

[0016] Optionally, the container also includes a seal that abuts against the container body and the cover when the cover closes the unloading port to seal the gap between the container body and the cover.

[0017] Optionally, the container also includes a second locking rod assembly, which is spaced apart from the first locking rod, and is used to lock the cover plate covering the unloading port to the container body. Attached Figure Description

[0021] In the following description, numerous specific details are set forth to provide a more thorough understanding of this application. However, it will be apparent to those skilled in the art that embodiments of this application may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with embodiments of this application.

[0022] The preferred embodiments of this application will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0023] In this document, ordinal numbers such as “first” and “second” used in this application are merely identifiers and do not include any other meaning, such as a specific order.

[0024] To fully understand the embodiments of this application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may also include other embodiments.

[0025] This embodiment provides a cover plate assembly. The cover plate assembly can be used in a container. The container is a bulk cargo container used for transporting granular bulk cargo (e.g., powder). When the cover plate 150 of the cover plate assembly closes the discharge port 141 of the container body 130, the pressing member 111 of the cover plate assembly presses the cover plate 150 tightly against the container body 130, thereby locking the cover plate 150. When the cover plate 150 closes the discharge port 141, the position of the contact point between the pressing member 111 and the cover plate 150 along the thickness direction of the cover plate 150 is adjustable, thereby allowing adjustment of the sealing degree between the cover plate 150 and the container body 130. When the cover plate 150 closes the discharge port 141, the thickness direction of the cover plate 150 is parallel to the length direction of the container body 130.

[0026] Please refer to Figures 1 to 4The cover assembly includes a cover plate 150 and a first locking rod component. The container includes a body 130 and a seal 120. The cover plate 150 includes a cover plate body 190. The thickness direction of the cover plate body 190 is the same as the thickness direction of the cover plate 150. The body 130 includes a base frame, vertical walls, and a top wall. The vertical walls include two end walls 140 and two side walls. The ends of the end walls 140 are connected to the ends of the side walls. The base frame, end walls 140, side walls, and top wall form a rectangular parallelepiped structure with approximately six sealed sides.

[0027] Among them, such as Figure 1 As shown, end wall 140 includes an end wall frame and end wall panels. The end wall frame includes corner posts, a bottom beam, and a top beam. The corner posts, bottom beam, and top beam form a generally rectangular frame. The frame also includes reinforcing beams. The length direction of the reinforcing beams is parallel to the length direction of the bottom beams. The reinforcing beams are located between the bottom beams and the top beams. The two ends of the reinforcing beams are connected (e.g., welded) to two corner posts respectively. Thus, end wall 140 has high strength. End wall panels are laid on the end wall frame.

[0028] Please continue to refer to this. Figure 1 A discharge port 141 is provided at the lower end of an end wall 140. The discharge port 141 is located between the reinforcing crossbeam and the bottom end beam. The discharge port 141 communicates with the internal space of the housing 130. The first end of the cover plate body 190 is pivotally connected to the housing 130 to rotate between an open position with the discharge port 141 open and a closed position with the discharge port 141 closed. The pivot axis of the cover plate body 190 extends along the height direction of the housing 130. When the cover plate body 190 closes the discharge port 141 (that is, when the cover plate 150 closes the discharge port 141), the cover plate body 190 presses the sealing element 120 against the housing 130, thereby sealing the gap between the housing 130 and the cover plate body 190. A first locking rod component is used to lock the cover plate body 190 with the discharge port 141 closed to the housing 130 (that is, to lock the cover plate 150 to the housing 130).

[0029] It is understood that, in embodiments not shown, the discharge port may also be located on the side wall.

[0030] This article describes the various directions using the example of a cover assembly installed in the container body 130.

[0031] like Figures 2 to 4As shown, the first locking rod component includes a first locking rod 110. The first locking rod 110 can be a rod-shaped structure. The first locking rod 110 can be cylindrical, such as a round bar or a round tube. The first locking rod 110 is rotatably mounted on the end wall 140 of the housing 130. The length direction of the first locking rod 110 is parallel to the height direction of the housing 130. When the cover plate body 190 covers the discharge port 141, the first locking rod 110 is located on the side of the second end of the cover plate body 190 away from the first end of the cover plate body 190. Along the width direction of the housing 130, the second end and the first end of the cover plate body 190 are arranged back to back.

[0032] Please continue to refer to this. Figures 2 to 4 The first locking rod component also includes a pressure member 111. One end of the pressure member 111 is fixedly connected (e.g., welded) to the outer peripheral surface of the first locking rod 110. The other end of the pressure member 111 is located outside the first locking rod 110. Thus, when the first locking rod 110 rotates, it drives the pressure member 111 to rotate. When the cover plate body 190 closes the discharge port 141, the pressure member 111 can rotate to the outer side of the second end of the cover plate body 190 along the length direction of the housing 130. Thus, by continuing to rotate the first locking rod 110, the pressure member 111 can press the second end of the cover plate body 190 covering the discharge port 141 against the housing 130, thereby locking the cover plate body 190 covering the discharge port 141 against the housing 130.

[0033] like Figures 2 to 4 As shown, the cover assembly also includes an adjusting member 115. The adjusting member 115 is for connection to the cover 150. The position of the adjusting member 115 along the thickness direction of the cover body 190 is adjustable. The pressing member 111 acts on the cover 150 or protrudes to the adjusting member 115 on the outer side of the cover 150 along the thickness direction of the cover 150, thereby pressing the cover body 190 of the discharge port 141 of the housing 130 against the housing 130.

[0034] In this way, the adjusting member 115 can move between the extended position and the retracted position. When the adjusting member 115 is in the extended position, the adjusting member 115 protrudes to the outer side of the pressure plate portion 171 along the thickness direction of the cover plate body 190 (described later). When the adjusting member 115 is in the retracted position, the adjusting member 115 does not protrude to the outer side of the pressure plate portion 171 along the thickness direction of the cover plate body 190.

[0035] When the cover plate body 190 closes the discharge port 141, the pressure member 111 can rotate to the adjustment member 115. At this time, if the adjustment member 115 is in the extended position, the pressure member 111 acts on the portion of the adjustment member 115 that protrudes to the outer side of the cover plate body 190 along the thickness direction of the pressure plate portion 171 (described later). If the adjustment member 115 is in the received position, the pressure member 111 acts on the outer side of the pressure plate portion 171 (described later) along the thickness direction of the cover plate body 190.

[0036] It is understood that, in embodiments not shown, the support member described later may not be provided. In this case, the adjusting member is directly connected to the cover plate body. The pressing member acts directly on the cover plate body. Specifically, when the adjusting member is in the extended position, it protrudes to the outer side of the cover plate body along its thickness direction. When the adjusting member is in the receiving position, it does not protrude to the outer side of the cover plate body along its thickness direction. When the cover plate closes the discharge port, the pressing member can rotate to the adjusting member. If the adjusting member is in the receiving position, the pressing member acts on the outer side of the cover plate body along its thickness direction. If the adjusting member is in the extended position, the pressing member acts on the portion of the adjusting member that protrudes to the outer side of the cover plate body along its thickness direction.

[0037] In this text, when the cover plate body 190 covers the discharge port 141, the outer side of part A along the reference direction is located on the side of part A away from the center of the housing 130 along the reference direction. When the cover plate body 190 covers the discharge port 141, the outer side of part A along the reference direction is the side of part A away from the center of the housing 130 along the reference direction.

[0038] For example, when the cover body 190 covers the discharge port 141, the outer side of the cover body 190 along the length direction of the housing 130 is located on the side of the cover body 190 away from the center of the housing 130 along the length direction of the housing 130. When the cover body 190 covers the discharge port 141, the outer side of the cover body 190 along the length direction of the housing 130 is the side of the cover body 190 away from the center of the housing 130 along the length direction of the housing 130.

[0039] If, after prolonged use, the cover body 190 of the unloading port 141 cannot be sealed when the locking part 114 locks the handle 113 to lock the cover plate body 190. In this case, the position of the adjusting part 115 is adjusted to increase the length of the protruding part of the adjusting part 115 (the part protruding to the pressure plate part 171). Thus, when the cover body 190 of the unloading port 141 is locked, the cover body 190 can seal the unloading port 141. If the cover body 190 cannot seal the unloading port 141 when it is locked, there is a gap between the cover body 190 and the container body, through which bulk cargo can leak out of the container body 130.

[0040] Furthermore, by adjusting the position of the adjusting member 115, the length of the protruding part of the adjusting member 115 can be adjusted, thereby adjusting the degree of pressure of the cover plate body 190 on the box body 130 when the cover plate body 190 of the cover plate 141 is locked, and thus adjusting the sealing performance of the cover plate body 190 covering the discharge port 141.

[0041] In addition, such as Figure 2 As shown, when the first locking rod component locks the cover plate body 190 of the discharge port 141, the pressing member 111 covers the adjusting member 115. The pressing member 111 shields the adjusting member 115. In this way, the adjusting member 115 can be protected.

[0042] In this embodiment, when the cover plate 150 of the locked discharge port 141 cannot seal the discharge port 141, the position of the adjusting member 115 is adjusted to increase the length of the protruding part of the adjusting member 115. In this way, when the cover plate 150 of the discharge port 141 is locked, the cover plate 150 can seal the discharge port 141. By adjusting the position of the adjusting member 115, the length of the protruding part of the adjusting member 115 can be adjusted, thereby adjusting the degree of pressure of the cover plate 150 on the box body 130 when the cover plate 150 of the discharge port 141 is locked, and thus adjusting the sealing performance of the cover plate 150 covering the discharge port 141.

[0043] Optionally, such as Figure 2 As shown, the first locking rod component also includes a mounting base 112. The mounting base 112 is fixedly connected (e.g., welded) to the end wall 140 of the housing 130. The mounting base 112 has a mounting hole. The first locking rod 110 is rotatably inserted through the mounting hole. The first locking rod component includes at least two (e.g., two) mounting bases 112. At least two mounting bases 112 are arranged sequentially at intervals along the height direction of the housing 130. Thus, the connection strength between the first locking rod 110 and the housing 130 is high.

[0044] Optionally, such as Figure 2 As shown, the pressure member 111 can be a flat plate structure. Therefore, the structure of the pressure member 111 is simple.

[0045] Alternatively, please refer to Figures 2 to 4 The adjusting element 115 can be a bolt, such as an internal hex bolt. The adjusting element 115 is threaded to the cover plate 150. Thus, turning the adjusting element 115 can adjust its position, making it easy to adjust.

[0046] like Figures 2 to 4As shown, the cover plate 150 also includes a support member 170. The support member 170 is used for a fixed connection (e.g., welding) to the cover plate body 190. The support member 170 includes a pressure plate portion 171. The pressure plate portion 171 has a flat plate structure. The pressure plate portion 171 is located on the outer side of the cover plate body 190 along the thickness direction of the cover plate body 190, and is spaced apart from the outer side surface of the cover plate body 190 along the thickness direction of the cover plate body 190.

[0047] An adjusting member 115 passes through the pressure plate portion 171. The pressure member 111 acts on the support member 170 or extends outward along the thickness direction of the adjusting member 115 to the pressure plate portion 171. As a result, there is no need to provide a hole in the cover plate body 190 to connect the adjusting member 115, and the strength of the cover plate body 190 is high.

[0048] Furthermore, the support member 170 is a sheet metal part formed by bending a sheet metal piece. The support member 170 also includes a connecting plate portion 172. The connecting plate portion 172 has a flat plate structure. The plane containing the connecting plate portion 172 intersects (e.g., is perpendicular to) the plane containing the pressure plate portion 171. One end of the connecting plate portion 172 is connected to the end of the pressure plate portion 171. The other end of the connecting plate portion 172 is used to connect to the outer surface of the cover plate body 190 along the thickness direction of the cover plate body 190. Thus, the structure of the support member 170 is simple.

[0049] Furthermore, the support member 170 includes two spaced-apart connecting plate portions 172. The two connecting plate portions 172 and the pressure plate portion 171 form a generally C-shaped structure. As a result, the support member 170 has high strength.

[0050] Optionally, such as Figure 3 and Figure 4 As shown, the support member 170 also includes a reinforcing portion 173. The reinforcing portion 173 is located to the side of the pressure plate portion 171. For example, the reinforcing portion 173 is located between the pressure plate portion 171 and the cover plate body 190. The reinforcing portion 173 is connected to the side of the pressure plate portion 171. The reinforcing portion 173 has a threaded hole. For example, the reinforcing portion 173 can be a nut welded to the pressure plate portion 171.

[0051] The pressure plate portion 171 has a mounting hole. The mounting hole communicates with the threaded hole of the reinforcing portion 173. The adjusting member 115 includes a rod portion 116 and a head 117. The outer diameter of the head 117 is larger than the outer diameter of the rod portion 116. The rod portion 116 has external threads. The rod portion 116 passes through the mounting hole and then into the threaded hole. The rod portion 116 and the threaded hole are threadedly connected. Figure 3 As shown, when the adjusting member 115 is in the receiving position, the head 117 is completely within the mounting hole. Figure 4As shown, when the adjusting member 115 is in the extended position, part of the head 117 is outside the mounting hole. Therefore, the thickness of the connection between the support member 170 and the adjusting member 115 is large, resulting in high connection strength.

[0052] It is understood that, in embodiments not shown, the reinforcing portion may also be located on the outer side of the pressure plate portion along the thickness direction of the cover plate body. In this case, the pressure plate is used to press the reinforcing portion, thereby acting on the cover plate through the support member.

[0053] Optionally, such as Figure 3 and Figure 4 As shown, the cover assembly also includes a limiting member 180. The limiting member 180 has a threaded hole. The limiting member 180 is disposed within the gap between the cover body 190 and the pressure plate portion 171, and is connected (e.g., threaded connection) to the adjusting member 115. Thus, the limiting member 180 can prevent the adjusting member 115 from moving away from the support member 170.

[0054] Furthermore, the limiting member 180 can be a nut. The cover plate assembly also includes an elastic washer. The elastic washer is sleeved on the rod portion 116 of the adjusting member 115 and is located between the limiting member 180 and the reinforcing portion 173. The limiting member 180 is threadedly connected to the adjusting member 115. Tightening the limiting member 180 allows it to grip the reinforcing portion 173 via the elastic washer, thereby reducing the possibility of the adjusting member 115 becoming loose.

[0055] It is understood that, in embodiments not shown, the mounting hole of the pressure plate is a threaded hole. The adjusting member is threadedly connected to the mounting hole. At this time, the head of the adjusting member is located on the outer side of the pressure plate along the thickness direction of the cover plate body. The cover plate assembly also includes an elastic washer. The elastic washer is sleeved on the rod portion of the adjusting member. The elastic washer is located between the head of the adjusting member and the pressure plate, thereby reducing the possibility of the adjusting member loosening. When the adjusting member is in the extended position, the head of the adjusting member presses the elastic washer against the pressure plate, and the pressure member can press against the head of the adjusting member, thereby acting on the cover plate through the adjusting member.

[0056] This application also provides a container. The container includes the aforementioned container body 130 and cover assembly.

[0057] In this embodiment, the container includes the aforementioned cover assembly. When the cover 150 of the locked unloading port 141 cannot seal the unloading port 141, the position of the adjusting member 115 is adjusted to increase the length of the protruding part of the adjusting member 115. In this way, when the cover 150 of the locked unloading port 141 is locked, the cover 150 can seal the unloading port 141. By adjusting the position of the adjusting member 115, thereby adjusting the length of the protruding part of the adjusting member 115, the degree of pressure of the cover 150 on the container body 130 when the cover 150 of the locked unloading port 141 can be adjusted, thereby adjusting the sealing performance of the cover 150 covering the unloading port 141.

[0058] Alternatively, please refer to Figures 2 to 4 The sealing element 120 can be a sealing strip. The sealing element 120 is connected to the cover plate body 190. When the cover plate body 190 closes the discharge port 141, the cover plate body 190 presses the sealing element 120 against the housing 130. In this way, the sealing element 120 abuts against the housing 130 and the cover plate body 190 to seal the gap between the housing 130 and the cover plate body 190.

[0059] After prolonged use, the seal 120 ages and deforms. At this point, when the cover body 190 closes the unloading port 141 to press the seal 120 against the container body 130, the compression of the seal 120 is insufficient, and it cannot seal the gap between the cover body 190 and the container body 130. By adjusting the position of the adjusting member 115 to its extended position, the length of the protruding portion of the adjusting member 115 is adjusted. Thus, when the cover body 190 is locked over the unloading port 141, it can further compress the seal 120, ensuring sufficient compression to seal the gap between the cover body 190 and the container body 130.

[0060] When the seal 120 is not aged, when the cover plate body 190 covering the discharge port 141 presses the seal 120 against the housing 130, the compression of the seal 120 can seal the gap between the housing 130 and the cover plate body 190. At this time, the adjusting member 115 can be placed in the receiving position.

[0061] Optionally, such as Figure 1 As shown, along the width direction of the container 130, the discharge port 141 is located approximately in the middle of the end wall 140. The discharge port 141 is located at the lower end of the end wall 140. Along the width direction of the container 130, the size of the discharge port 141 is 1 / 4 to 1 / 3 of the width dimension of the container 130. Along the height direction of the container 130, the size of the discharge port 141 is 1 / 4 to 1 / 3 of the height dimension of the container 130. This facilitates the discharge of bulk goods from the container 130 through the discharge port 141.

[0062] Optionally, such as Figure 1 and Figure 2 As shown, the container also includes a second locking rod component 160. The second locking rod component 160 can be an existing locking rod component. The second locking rod component 160 includes a second locking rod of the existing locking rod component, a locking head disposed at the end of the second locking rod, and a locking seat disposed on the container body. The second locking rod component 160 is spaced apart from the first locking rod 110. When the cover body 190 closes the unloading port 141, the second locking rod component 160 is located approximately at the center of the cover body 190 along the width direction of the container body 130. The locking head and locking seat of the second locking rod component 160 cooperate to lock the cover body 190 of the unloading port 141 to the container body 130. The axial direction of the second locking rod of the second locking rod component 160 is parallel to the height direction of the container body 130. Thus, the second locking rod component 160 and the first locking rod component work together to more securely lock the cover body 190 of the unloading port 141.

[0063] like Figure 1 and Figure 2 As shown, the first locking lever assembly also includes a handle 113 and a locking component 114. One end of the handle 113 is connected to the first locking lever 110, enabling the handle 113 to rotate the first locking lever 110. The handle 113 is rotatable relative to the first locking lever 110. The axis of rotation of the handle 113 is perpendicular to the axis of the first locking lever 110. The locking component 114 is disposed on the outer surface of the cover body 190 along the thickness direction of the cover body. When the cover body 190 is in the closed position, the locking component 114 locks the handle 113 to prevent the first locking lever 110 from rotating. The handle 113 and the locking component 114 can be the handle and locking component of an existing container second locking lever assembly, which will not be described further here.
