Description

Technical Field

[0001] The utility model relates to the technical field of containers, and more specifically to a door end corner assembly of a container and the container. Background Art

[0002] Containers have been widely used as a tool for logistics transportation. With the different types of goods and areas of use, some special containers have been derived. At present, a container with a length of more than 40 feet is used in some specific areas. Its box body has a middle frame (40 feet position) and two end frames (door end and front end position). During transportation, they only use the top corners of the middle frame for stacking and lifting, while the top corners of the end frames are not stacked or lifted. Therefore, corner pieces are usually not set at the top corners of the end frames.

[0003] The top corner assembly of the door end of the container includes a lintel, a corner post and a corner top plate. In the production process, the usual practice is to first weld the corner top plate with the corner post to form a component, and then weld the component as a whole to the lintel. Due to the structural characteristics of the corner top plate, the weld between the lintel and the corner post will be covered and welding will not be possible; or the corner post and the lintel are welded together, and then the corner top plate is covered and welded. In this way, the hidden weld between the lintel and the corner post will still be leaked and difficult to detect. As a result, the connection strength between the lintel and the corner post is limited, affecting the structural strength of the container, especially the door end of the container. In addition, the top surface of the corner top plate of the door end of the container is currently coplanar with the top angle surface of the middle frame. When stacked at the middle frame position, it will inevitably cause the top corner of the door end to be stressed, causing the door frame to deform, thereby affecting the opening and closing of the door. Finally, after the corner top plate is welded, its weld is on the top surface of the box body. If this weld has defects, there will be a risk of water leakage in the future. Utility Model Content

[0046] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0047] In this document, ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of the "second component", and the term "second component" itself does not imply the existence of the "first component".

[0048] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0049] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0050] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0051] Figure 1 An existing container is shown, including a box body 100, wherein the box body 100 is provided with a middle frame 101, and the middle frame 101 is provided with top corner fittings 102. When the containers are stacked, the top corner fittings 102 of the middle frame 101 are connected to the corresponding positions of the upper containers.

[0052] The middle frame 101 of the container may be spaced apart from the top corners of the box body 100 along the length direction D2 of the container. Figure 2 The top corner of the box 100 includes the lintel 104, the corner post 103 and the corner top plate 105. When the corner top plate 105 is first welded to the corner post 103 and then welded to the lintel 104 as a whole, the cover of the corner top plate 105 will cause the weld bead between the lintel 104 and the corner post 103 to be unable to be welded. Alternatively, after the corner post 103 is welded to the lintel 104, the corner top plate 105 is then covered and welded. In this way, the hidden weld bead between the lintel 104 and the corner post 103 is still leaked and not easy to detect. As a result, the connection strength between the lintel 104 and the corner post 103 is limited, affecting the structural strength of the container, especially the door end of the container. In addition, after the corner top plate 105 is welded to the lintel 104, its weld bead is on the top surface of the box 100. If this weld bead has defects, there will be a risk of water leakage in the future.

[0053] In addition, refer to Figure 1 and Figure 2 , the distance h1 between the top surface of the current top corner 110 and the bottom surface of the box body 100 is equal to the distance h2 between the top surface of the top corner fitting 102 and the bottom surface of the box body 100. In other words, in the actual production process, the top surface of the corner top plate 105 and the top surface of the top corner fitting 102 are arranged coplanarly, so when the containers are stacked through the top corner fittings 102 of the middle frame 101, due to the inevitable errors in the manufacturing process, the top corner 110 of the container will be subjected to force due to the stacking, causing the door end to deform, thereby affecting the operation of opening and closing the container door.

[0054] The present invention is described in detail below through a number of specific implementations.

[0055] First embodiment

[0056] Figure 3 A container according to the first embodiment is shown, comprising a box body 270, a middle frame 280 and a door end corner assembly 210, wherein the middle frame 280 is arranged on the box body 270, and the middle frame 280 is provided with a corner piece 290. The door end corner assembly 210 is arranged at the end of the box body 270.

[0057] Figure 5 The above-mentioned door end corner assembly 210 of the container is shown, and the door end corner assembly 210 includes an inner corner post 220, an outer corner post 230, a door lintel 240, and a door lintel plate 250. The inner corner post 220 extends in the height direction D1 of the container. The outer corner post 230 is connected to the inner corner post 220, and the top surface of the outer corner post 230 protrudes from the top surface of the inner corner post 220 in the height direction D1. The end of the door lintel 240 is connected to the top surface of the inner corner post 220 and is connected to the side wall of the outer corner post 230 protruding from the inner corner post 220. The door lintel plate 250 is connected to the top of the door lintel 240, and the door lintel plate 250 extends in the width direction D3 of the container and is connected to the outer corner post 230.

[0058] According to the container door end top corner assembly 210 of the first embodiment, the provision of the corner top plate is cancelled, so that the inner corner column 220 and the outer corner column 230 are directly connected to the door lintel 240 and the door lintel plate 250, so that the connection strength and rigidity between the various components are improved. In addition, the door end top corner assembly 210 has good integrity and is easy to process and weld. Finally, there is no weld bead on the top of the door end top corner assembly 210, which has good sealing performance and does not need to worry about the risk of water leakage from the top in the future.

[0059] Preferably, refer to Figure 5 The lintel plate 250 extends along the width direction D3 to the top surface of the outer corner column 230, so that the welds of the lintel plate 250 and the outer corner column 230 are shielded by the lintel plate 250, so that the welds have good sealing properties, and there is no need to worry about the risk of water leakage from the top in the future.

[0060] Specific reference Figure 3 and Figure 4 , the top corner assembly 210 of the container door end has no corner top plate, so the top surface of the door lintel plate 250 is the highest surface of the door end corner. Along the height direction D1 of the container, the distance h3 from the top surface of the door lintel plate 250 to the bottom surface of the box body 270 is smaller than the distance h4 from the top surface of the top corner piece 290 to the bottom surface of the box body 270, and h4-h3=h', h'>0. Therefore, the door end top corner assembly 210 will not be subjected to force when the top corner pieces 290 of the container middle frame 280 are stacked, causing the door end of the container to deform, thereby not affecting the operation of opening and closing the door at the door end of the container.

[0061] Further, see Figure 5 The sum h5 of the dimensions of the lintel plate 250 and the lintel 240 along the height direction D1 is greater than the dimension h6 of the outer corner column 230 protruding from the inner corner column 220 along the height direction D1, so that the lintel plate 250 can protrude from the top surface of the outer corner column 230 along the height direction D1, so that the lintel plate 250 can protect the welding points between the lintel 240, the inner corner column 220, the outer corner column 230 and the lintel plate 250.

[0062] Preferably, the top surface of the door lintel 240 is flush with the top surface of the outer corner post 230, and the door lintel plate 250 is higher than the top surface of the outer corner post 230, and the door lintel plate 250 extends to the outside of the outer corner post 230 along the width direction D3, so that the welding seam between the door lintel plate 250 and the outer corner post 230 is covered by the door lintel plate 250, which can prevent external rainwater from corroding the welding seam between the door lintel plate 250 and the outer corner post 230, thereby facilitating the sealing of the door end top corner assembly 210.

[0063] Optionally, refer to Figure 6 , the sum h5 of the dimensions of the lintel plate 250 and the lintel 240 along the height direction D1 is equal to or less than the dimension h7 of the outer corner post 230 protruding from the inner corner post 220 along the height direction D1, so that the welding between the lintel plate 250 and the outer corner post 230 can be easily implemented while ensuring the welding quality. However, h7-h5<h' must be satisfied to ensure that the door end top corner assembly 210 will not be stressed when the top corner pieces 290 of the middle frame 280 of the container are stacked, thereby preventing the door end of the container from being deformed, thereby not affecting the operation of opening and closing the door at the door end of the container.

[0064] Optionally, the lintel plate 250 extends to the inner side of the outer corner post 230 along the width direction D3 , so that the lintel plate 250 and the outer corner post 230 are connected together.

[0065] As an alternative, refer to Figure 6 Along the height direction D1 of the container, the distance between the top surface of the outer corner column 230 and the bottom surface of the box body 100 is smaller than the distance between the top surface of the top corner fitting 102 and the bottom surface of the box body 100. This can also prevent the door end top corner assembly 210 from being subjected to force when the top corner fittings 290 of the container middle frame 280 are stacked, thereby preventing the door end of the container from being deformed, thereby not affecting the operation of opening and closing the door at the door end of the container.

[0066] Preferably, the door lintel plate 250 and the outer corner column 230, the door lintel 240 and the outer corner column 230, the door lintel 240 and the inner corner column 220, and the outer corner column 230 and the inner corner column 220 are all fully welded, which has good sealing performance and high connection strength.

[0067] Second embodiment

[0068] Figure 7A container door end corner assembly 210 according to a second embodiment is shown. Compared with the container door end corner assembly 210 according to the first embodiment, the difference lies in that: the door lintel plate 250 is provided with a first bent edge 351, and the first bent edge 351 extends to the outside of the outer corner column 230 along the height direction D1, so that the welding seam between the door lintel plate 250 and the outer corner column 230 is further covered by the door lintel plate 250, which can prevent the welding seam between the door lintel plate 250 and the outer corner column 230 from being corroded by external rainwater, thereby facilitating the sealing of the door end corner assembly 210.

[0069] Preferably, the first bent edge is attached to and connected to the outer side wall of the outer corner column 230 , so as to further enhance the sealing property and connection strength between the lintel plate 250 and the outer corner column 230 .

[0070] Third embodiment

[0071] Figure 8 A container door end corner assembly 210 according to a third embodiment is shown. Compared with the container door end corner assembly 210 according to the first embodiment, the container door end corner assembly 210 according to the third embodiment includes a reinforcement member 460 .

[0072] Specifically, refer to Figure 8 The reinforcement member 460 is at least partially located in the outer corner column 230 , and the reinforcement member 460 is connected to the outer corner column 230 and the door lintel 240 , respectively, thereby further strengthening the connection between the outer corner column 230 and the door lintel 240 , and also improving the overall rigidity of the door end top angle assembly 210 .

[0073] Further, see Figure 8 The outer corner column 230 is provided with a second bent edge 431, which extends along the width direction D3 and is spaced apart from the inner corner column 220 along the length direction D2 of the container. The reinforcement member 460 is connected between the second bent edge 431 and the inner corner column 220, and has a compact structure, which can further enhance the connection strength between the inner corner column 220 and the outer corner column 230.

[0074] Optionally, the reinforcement member 460 is provided with a third bent edge 461, which extends along the width direction D3 and is connected to the end top surface of the outer corner column 230. The third bent edge 461 is connected to the lintel plate 250, thereby further strengthening the connection strength between the lintel plate 250 and the outer corner column 230. The provision of the third bent edge 461 enhances the overall strength of the reinforcement member 460, thereby improving the overall strength of the door end top corner assembly 210.

[0075] Reference Figure 8The bottom of the reinforcement member 460 further has a fourth bent edge 462. The fourth bent edge 462 extends along the width direction D3 and is connected to the inner side of the outer corner column 230. In this way, the reinforcement member 460, the outer corner column 230, the inner corner column 220, the door lintel 240 and the door lintel plate 250 are constructed to form a closed box body, which greatly improves the overall strength of the door end top corner assembly 210.
