[0094] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings. These drawings illustrate representative embodiments of the present application and do not limit the present application.

[0095] With the in-depth development of infrastructure construction in China, prefabricated electrical containers are widely used in the construction of electrical-related infrastructure across the country to improve construction efficiency, shorten the construction period, and reduce costs. However, the doors 100 of existing prefabricated electrical containers largely adopt the design structure of the doors 100 of standard marine containers. The waterproof ability test of the doors 100 of standard marine containers uses a weathertight test, which is insufficient for electrical containers with high waterproof requirements. Electrical containers often require an IPx5 protection level or even higher in GB4208-2017 Degrees of protection provided by enclosures (IP code) or IEC60529:2013 Degrees of protection provided by enclosures (IP code).

[0096] Electrical prefabricated containers have fireproof and heat insulation requirements, so their structures usually consist of a three-layer structure of an outer door steel plate, a fireproof / heat insulation layer, and an inner decoration steel plate from the outside to the inside. The joints between the inner decoration steel plate and the door panel structure columns and the outer door steel plate are often on the side of the door panel. In related technologies, many designs consider placing this joint behind a sealing strip 150 such as a C-J shaped rubber strip. This joint is sealed by spot welding and caulking. After covering the sealing strip 150, caulking is applied outside the rubber strip. However, since the sealing strip 150 is deformed or even displaced under force during the opening and closing of the door 100, the sealant between the sealing strip 150 and the door panel is easily pulled and cracked, resulting in seal failure and allowing water to easily enter the door panel. If the joint on the side of the door panel is fully welded, there are defects such as a large amount of welding and easy deformation of the door panel.

[0097] To solve the above technical problems, some embodiments of the present application provide a door and a container having the door. The container here may include, but is not limited to, an electrical container capable of integrating electrical equipment.

[0098] Such as Figures 1 to 17As shown, the door 100 according to some embodiments of the present application may include a first plate member 110 and a second plate member 120. The first plate member 110 and the second plate member 120 are connected to form the external structure of the door panel. The first plate member 110 and the second plate member 120 are each made of a plate material or formed into a plate-like structure. The first plate member 110 may include a panel portion 111, two side plate portions 112, a top plate portion 113, and a bottom plate portion 114. The side plate portions 112, the top plate portion 113, and the bottom plate portion 114 are all located inside the panel portion 111 along the first direction D1. The panel portion 111 has an inner side and an outer side opposite to each other in the first direction D1. The inner side of the panel portion 111 here can be understood as the side of the panel portion 111 facing the inside of the door 100 along the first direction D1. Correspondingly, the outer side can be understood as the side of the panel portion 111 facing the outside of the door 100 along the first direction D1. The side plate portions 112, the top plate portion 113, and the bottom plate portion 114 each intersect the panel portion 111. Taking the side plate portion 112 as an example, the surface of the side plate portion 112 intersects the surface of the panel portion 111, or the thickness direction of the side plate portion 112 intersects the thickness direction of the panel portion 111. The two side plate portions 112 are disposed opposite to each other in the second direction D2. And the two side plate portions 112 are each connected to both ends of the panel portion 111 along the second direction D2. The top plate portion 113 and the bottom plate portion 114 are disposed opposite to each other in the third direction D3. The top plate portion 113 and the bottom plate portion 114 are each connected to both ends of the panel portion 111 along the third direction D3. The panel portion 111, the side plate portions 112, the top plate portion 113, and the bottom plate portion 114 are integrally formed. Any two of the first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. The second plate member 120 is located inside the panel portion 111 along the first direction D1. The second plate member 120 and the panel portion 111 are spaced apart in the first direction D1. The second plate member 120 is connected to the ends of the side plate portions 112, the top plate portion 113, and the bottom plate portion 114 that are away from the panel portion 111.

[0099] Wherein, the side plate portions 112, the top plate portion 113, and the bottom plate portion 114 are located at the outer peripheral side portion of the door 100. The end portion of the panel portion 111 in the thickness direction of the door 100 that is adapted to face the outside of the container. That is, the panel portion 111 can be understood as the outer door panel of the door 100. The first plate member 110 is located at the end portion of the door 100 in the thickness direction that is adapted to face the inside of the container. That is, the first plate member 110 can be understood as the inner door panel or the interior panel of the door 100.

[0100] As shown in the figure, in an embodiment where the outer contour shape of the panel portion 111 is square, the first direction D1 can be understood as the thickness direction of the panel portion 111, the second direction D2 can be understood as the width direction of the panel portion 111, and the third direction D3 can be understood as the height direction of the panel portion 111. Thus, the two side plate portions 112 are located at opposite ends in the width direction of the panel portion 111, the top plate portion 113 is located at the upper end in the height direction of the panel portion 111, and the bottom plate portion 114 is located at the lower end in the height direction of the panel portion 111.

[0101] For the door 100 according to the embodiment of the present application, by integrally forming the panel portion 111, the two side plate portions 112, the top plate portion 113, and the bottom plate portion 114 of the first plate member 110, there are gaps mainly between the side plate portion 112 and the top plate portion 113 and between the side plate portion 112 and the bottom plate portion 114 at the outer peripheral side portion of the door 100. Thus, the gaps at the outer peripheral side portion of the door 100 can be reduced, and the probability of water seeping into the interior of the door 100 from the outer peripheral side of the door 100 can be decreased, thereby improving the water seepage prevention performance of the door 100.

[0102] Refer to Figures 4 to 10 , optionally, the dimension of the side plate portion 112 in the third direction D3 is the same as the dimension of the panel portion 111 in the third direction D3, for example, they are equal. The dimension of the top plate portion 113 in the second direction D2 is the same as the dimension of the panel portion 111 in the second direction D2, for example, they are equal. The dimension of the bottom plate portion 114 in the second direction D2 is the same as the dimension of the panel portion 111 in the second direction D2, for example, they are equal. Further, the dimensions of the side plate portion 112, the top plate portion 113, and the bottom plate portion 114 in the first direction D1 are the same, for example, equal. In this way, after the first plate member 110 and the second plate member 120 are assembled, it helps to ensure that the dimensions of each part of the door 100 in the first direction D1 are more uniform.

[0103] Refer to Figure 4 , in addition, the first plate member 110 may further include a first sealing portion 116. The first sealing portion 116 is connected circumferentially along the panel portion 111 between any two adjacent ones of the side plate portion 112, the top plate portion 113, and the bottom plate portion 114 to seal the gap between any two adjacent ones of the side plate portion 112, the top plate portion 113, and the bottom plate portion 114. That is, by providing the first sealing portion 116 here, the gap between any two adjacent ones of the side plate portion 112, the top plate portion 113, and the bottom plate portion 114 can be filled, thereby improving the sealing performance of the outer plate member of the door 100 at the circumferential side portion, and further reducing or avoiding water seepage at the outer peripheral side of the door 100.

[0104] Optionally, the first sealing portion 116 is configured as a structure formed by welding. The first sealing portion 116 is a structure formed when any two adjacent ones of the side plate portion 112, the top plate portion 113, and the bottom plate portion 114 of the first plate member 110 are welded. This structure can specifically be formed by the fusion of solder and the first plate member 110 during the welding process, or can be formed by the fusion of respective parts of any two adjacent ones of the side plate portion 112, the top plate portion 113, and the bottom plate portion 114 during the welding process.

[0105] Optionally, the first sealing portion 116 can also be sealant. Or the first sealing portion 116 is a structure formed by a combination of a welding portion formed by spot welding and sealant.

[0106] Refer to Figure 3 and Figure 12 Optionally, the first plate member 110 and the second plate member 120 enclose to form a door inner cavity 101. The door 100 of the cabinet can further include a door frame 140. The door frame 140 is located in the door inner cavity 101. The door frame 140 is connected to the first plate member 110 and the second plate member 120 to support the first plate member 110 and the second plate member 120.

[0107] Optionally, the first plate member 110 is configured as a sheet metal part made from a metal plate through sheet metal processing. In other words, the first plate member 110 is made from an entire metal plate such as a steel plate through sheet metal processes such as shearing and bending, which can ensure the integrity of the first plate member 110.

[0108] As Figures 4 to 10 shown, specifically, the first plate member 110 is made by bending a single steel plate through sheet metal processing, such that the front surface and the outer peripheral side surface of the door panel are integrally formed and folded back towards the back surface. The door cross beam 141, the door vertical beam 142, the reinforcing rib 143, etc. are made into sheet metal parts and hidden inside the door panel to form the door frame 140. The joint between the second plate member 120 and the first plate member 110 is designed on the back surface of the door 100 of the cabinet, so as to avoid the area on the door panel where the sealing strip 150 is arranged. Taking the door 100 of the cabinet as a square as an example, after the first plate member 110 is formed by sheet metal bending, there is one joint at each of the four corners, for a total of four joints. The joints extend along the first direction D1. After full welding treatment is performed on these four joints, there are no other joints or gaps at the part of the outer peripheral side surface of the door panel for installing the sealing strip 150, and there is no possibility of water seeping from behind the sealing strip 150 into the interior of the door 100 of the cabinet. Compared with the design of the door vertical beam 142, the door cross beam 141, the inner door corrugated plate, and the outer door corrugated plate for the door 100 of a marine container, the present application uses a single metal plate to integrally form the first plate member 110, which includes the structure of the front surface of the door panel and the outer peripheral side surface of the door panel. After being assembled with the second plate member 120, it can reduce the splicing welds on the outer peripheral side part of the relevant door 100, and the manufacturing cost is lower.

[0109] Optionally, the plate surfaces of the panel portion 111, the side plate portion 112, the top plate portion 113, and the bottom plate portion 114 of the first plate member 110 are each a plane. Thus, the overall appearance of the door panel structure of the cabinet door 100 is a flat door panel, which is more aesthetically pleasing and more in line with the general usage requirements of the electrical equipment industry.

[0110] Refer to Figures 7 to 10 , in addition, the first plate member 110 may further include a connecting portion 115. The connecting portion 115 extends in a direction intersecting the first direction D1, for example, perpendicularly. The connecting portion 115 is connected to at least one of the side plate portion 112, the top plate portion 113, and the bottom plate portion 114 at an end away from the panel portion 111. By providing the connecting portion 115, it can be used to connect to the second plate member 120, thereby improving the strength of the connection structure between the first plate member 110 and the second plate member 120, and to a certain extent facilitating the sealing of the connection portion 115 between the first plate member 110 and the second plate member 120.

[0111] For example, the first plate member 110 may include at least four connecting portions 115. Each of the connecting portions 115 is connected to an end of the side plate portion 112, the top plate portion 113, and the bottom plate portion 114 that is away from the panel portion 111. In the illustrated example, the first plate member 110 is provided with four connecting portions 115, and the four connecting portions 115 are connected to the ends of the two side plate portions 112, the top plate portion 113, and the bottom plate portion 114 that are away from the panel portion 111 in a one-to-one correspondence. This can further improve the strength of the connection structure between the first plate member 110 and the second plate member 120. At a position corresponding to any one of the side plate portion 112, the top plate portion 113, and the bottom plate portion 114, the connecting portions 115 are continuously arranged. Taking the connecting portion 115 at the side plate portion 112 as an example, the connecting portion 115 here extends continuously in the third direction D3, and the dimension of the connecting portion 115 in the third direction D3 may be the same as the dimension of the side plate portion 112 in the third direction D3. Here, being the same can be understood as being equal or having a slight deviation.

[0112] In some other embodiments, the first plate member 110 may include more than four connecting portions 115. At least one of the side plate portion 112, the top plate portion 113, and the bottom plate portion 114 is connected to at least two connecting portions 115, and the at least two connecting portions 115 are spaced apart from each other.

[0113] Inside the door 100 of an electrical container, there are often requirements for filling fireproof / thermal insulation materials and covering decorative panels inside the container. In the related technologies of converting marine containers into electrical containers, after installing components such as the lock rod 133 and the lock rod bracket 131 on the door 100 of the marine container, the design of applying sealant at the internal installation nut is difficult to implement in the usual construction process. Since the lock rod 133 is a movable part, if the original design of applying sealant inside is changed to the design of applying sealant at the external nail head or wrapping the thread with sealant before installation, there are problems such as poor reliability and uncertain construction effect, and the problem that water seeps into the inside of the door 100 from the installation position of the bolt 134 of the lock rod bracket 131 cannot be solved.

[0114] Refer to Figure 1 , Figure 3 , Figure 4 , and Figures 11 to 15 , in the door 100 of some embodiments of the present application, the first plate member 110 and the second plate member 120 enclose to form a door inner cavity 101. The panel portion 111 is provided with a first connection hole 111a. The door 100 may further include a lock rod bracket 131, a blind hole nut 117, and a bolt 134. The lock rod bracket 131 is located outside the panel portion 111. The lock rod bracket 131 is used to support or hold the lock rod 133. The lock rod 133 installed on the lock rod bracket 131 can move relative to the lock rod bracket 131. The lock rod bracket 131 is provided with a second connection hole 131a. The bolt 134 passes through the first connection hole 111a and the second connection hole 131a and is screwed to the blind hole nut 117 to fix the lock rod bracket 131 to the first plate member 110. The blind hole nut 117 can be understood as a nut with one end of the threaded hole 117e closed and the other end open. At least a part of one of the bolt 134 and the blind hole nut 117 is located in the door inner cavity 101 and is hermetically connected to the panel portion 111. By setting the blind hole nut 117 to be connected to the bolt 134, at least the infiltration of water into the inside of the door 100 from the connection part of the nut and the bolt 134 can be reduced or avoided, so that the problem of water seeping into the inside of the door 100 from the installation part of the lock rod bracket 131 and the door 100 can be solved.

[0115] Refer to Figure 14 and Figure 15 , optionally, the blind hole nut 117 is located in the door inner cavity 101. The blind hole nut 117 has a blind end 117a and an open end 117b opposite to each other along its own axis. The open end 117b is formed with an installation surface 117c adapted to fit the panel portion 111. By setting the installation surface 117c, the contact area between the blind hole nut 117 and the panel portion 111 in the installation state can be increased, thereby improving the sealing performance between the blind hole nut 117 and the panel portion 111. The installation surface 117c here is continuously arranged in the circumferential direction of the threaded hole 117e of the blind hole nut 117. Further, the installation surface 117c is an annular surface.

[0116] Refer to Figure 15 , further optionally, the blind hole nut 117 is welded to the panel portion 111. By welding the blind hole nut 117 to the panel portion 111, it is possible to facilitate the embedding of the blind hole nut 117 inside the door 100 during production, so that when assembling the lock rod assembly including the lock rod bracket 131, the lock rod assembly can be directly assembled to the door 100 by passing through and rotating the bolt 134, which is convenient for assembly. Moreover, since the blind hole nut 117 is fixed to the panel portion 111 by welding, the strength of the connection structure between the blind hole nut 117 and the panel portion 111 can be improved. Also, when the blind hole nut 117 and the panel portion 111 are fully welded, the sealing performance between the blind hole nut 117 and the panel portion 111 can be improved, thereby effectively preventing water from entering the inside of the door 100 through the gap between the blind hole nut 117 and the hole wall of the first connection hole 111a, further improving the waterproof performance of the installation part of the lock rod bracket 131 and the door 100.

[0117] Refer to Figure 14 and Figure 15 , for example, the open end 117b of the blind hole nut 117 may include a positioning boss 117d. The positioning boss 117d protrudes axially from the above-mentioned mounting surface 117c of the blind hole nut 117. The positioning boss 117d is located on the periphery of the threaded hole 117e of the blind hole nut 117. The positioning boss 117d is adapted to be inserted into the first connection hole 111a to limit the blind hole nut 117 in the radial direction of the first connection hole 111a. By providing the positioning boss 117d, it is convenient to position the blind hole nut 117 on the panel portion 111, thus facilitating the implementation of welding, and further helping to improve the welding efficiency.

[0118] Optionally, the positioning boss 117d extends continuously along the circumferential direction of the threaded hole 117e of the blind hole nut 117.

[0119] Refer to Figure 15 , in addition, the door 100 may further include a bracket gasket 132. The bracket gasket 132 is configured as a gasket made of a flexible and elastic soft rubber such as rubber. The bracket gasket 132 is provided with a mounting hole adapted to pass through the bolt 134. The aperture of the mounting hole is smaller than the outer diameter of the bolt 134. The bracket gasket 132 is located between the lock rod bracket 131 and the panel portion 111. The bolt 134 passes through the second connection hole 131a, the mounting hole and the first connection hole 111a in sequence and is screwed to the blind hole nut 117. By providing the bracket gasket 132, it is possible to seal the gap between the bolt 134 and the first connection hole 111a on the outer side of the panel portion 111, and also improve the sealing performance between the lock rod bracket 131 and the panel portion 111, thereby obtaining better waterproof performance at the installation location of the lock rod bracket 131.

[0120] For the door 100 according to this embodiment, by changing the nut for installing the lock rod bracket 131 in the related art to a special blind hole nut 117, before laying the heat insulation / fireproof layer on the back of the first plate 110 and installing the second plate 120, the blind hole nut 117 is placed in the first connection hole 111a pre-opened on the first plate 110. The above-mentioned blind hole nut 117 can be quickly positioned by relying on the positioning boss 117d and the first connection hole 111a, which can improve the positioning efficiency of the nut. The above-mentioned blind hole nut 117 can reduce the gap amount where the bolt 134 penetrates through the inner and outer sides of the door 100, thereby reducing the probability of water seepage at the bolt 134. During production, the blind hole nut 117 is installed by spot welding plus applying sealant (after the nut is spot welded, it is firmly combined with the first plate 110, so the sealant here is not affected by external forces when the door is opened and closed, ensuring reliability during use) or full welding, thereby completely isolating the inner and outer spaces of the door 100 at the bolt 134.

[0121] Electrical containers often have requirements of large load capacity and light self-weight, which will lead to insufficient rigidity of the container itself. At the same time, the civil engineering foundation often has low requirements for flatness, which makes the container have structural deformation and distortion after being placed on an uneven foundation, resulting in unevenness between the door 100 and the door frame 170 of the container. When the door 100 is closed, the sealing strip 150 does not fit well with the door frame 170, easily causing water leakage problems.

[0122] Refer to Figure 1 、 Figure 11 、 Figure 12 、 Figure 16 and Figure 17, according to some embodiments of the present application, the door 100 of the container may further include a sealing strip 150. The sealing strip 150 is continuously arranged on the outer peripheral side of the first plate member 110. That is, the sealing strip 150 is an integral sealing ring-shaped strip. In other words, the sealing strip 150 is annular, and the annular shape here can be understood as any closed shape such as a square, a circle, an ellipse, a polygon, etc. The sealing strip 150 may include at least one base portion 151, a first strip portion 152, and at least one second strip portion 153. The base portion 151 is connected to the side plate portion 112, the top plate portion 113, and the bottom plate portion 114. That is, the base portion 151 is connected to the outer peripheral side portion of the first plate member 110, and the outer peripheral side portion of the first plate member 110 does not include the above-mentioned panel portion 111 and the connecting portion 115. The first strip portion 152 is connected to the base portion 151 and extends at least along the second direction D2. The free end of the first strip portion 152 is adapted to contact the outer surface of the door frame 170, so as to seal the gap between the outer surfaces of the door 100 and the door frame 170, thereby preventing water from passing through the gap between the door 100 and the door frame 170. It can be understood that the outer surface of the door frame 170 here is the surface of the door frame 170 facing away from the inner space of the container. The second strip portion 153 is connected to the base portion 151 and extends at least along the second direction D2. The free end of the first strip portion 152 is adapted to contact the inner peripheral surface of the door frame 170, so as to seal the gap between the inner peripheral surfaces of the door 100 and the door frame 170, thereby preventing water from passing through the gap between the door 100 and the door frame 170. It can be understood that the inner peripheral surface of the door frame 170 here is the surface of the door frame 170 facing the outer peripheral side portion of the door 100 in the closed state.

[0123] Refer to Figure 12 , Figure 16 and Figure 17 , in some embodiments of the present application, the sealing strip 150 may include one base portion 151 and at least two second strip portions 153. The first strip portion 152 and each second strip portion 153 share the base portion 151, thereby ensuring the continuity of the base portion 151 between adjacent second strip portions 153 and between the first strip portion 152 and the second strip portion 153, and further improving the integrity and sealing performance of the sealing strip 150. Each second strip portion 153 is arranged at intervals in the first direction D1. By providing at least two second strip portions 153, at least two seals can be formed on the outer peripheral side portion of the door 100, so that the corresponding sealing ability can still be retained after one seal fails. That is, through the redundant design of the second strip portion 153, the sealing reliability and service life of the sealing strip 150 can be improved.

[0124] Furthermore, a glue groove 151a is formed on the surface of the base portion 151 facing the first plate member 110. The glue groove 151a is arranged continuously along the circumferential direction of the sealing strip 150. By providing the glue groove 151a on the base portion 151, it is convenient to more reliably position the sealing glue applied to the base portion 151 during production, so that the cured sealing glue can be continuous and closed along the circumferential direction of the first plate member 110 between the base portion 151 and the outer peripheral side portion of the first plate member 110, thereby improving the sealing performance between the sealing strip 150 and the first plate member 110, and further facilitating preventing water from infiltrating into the container through the connection between the sealing strip 150 and the first plate member 110, and improving the waterproof performance of the door 100 of the container.

[0125] Optionally, the base portion 151 may include at least two glue grooves 151a. The respective glue grooves 151a are arranged at intervals in the first direction D1. By providing at least two glue grooves 151a, at least two sealing structures formed by the sealing glue can be formed between the sealing strip 150 and the outer peripheral side portion of the first plate member 110, thereby improving the reliability of the seal and further improving the waterproof performance of the door 100 of the container.

[0126] Optionally, in the direction away from the base portion 151, the distance between the second rubber strip portion 153 and the second plate member 120 in the first direction D1 increases. That is, the free end of the second rubber strip portion 153 is bent or inclined towards the outside of the door 100 of the container, which can improve the water blocking performance of the second rubber strip portion 153. In other words, the root end 181d of the second rubber strip portion 153 is connected to the base portion 151, and the tip end 181e is located at one end of the second rubber strip portion 153 away from the base portion 151. The tip end 181e of the second rubber strip portion 153 is closer to the outside of the sealing strip 150 in the first direction D1 than the root end 181d. Moreover, usually, the door 100 of the container moves outward relative to the container body to open and moves inward to close. Thus, during the closing process of the door 100 of the container, the contact area between the longer second rubber strip portion 153 and the inner circumferential surface of the door frame 170 will gradually increase, which is more conducive to improving the sealing performance between the door 100 of the container and the door frame 170, and further improving the waterproof performance of the container.

[0127] Optionally, in the direction away from the base portion 151, the distance between the first rubber strip portion 152 and the second plate member 120 in the first direction D1 decreases. That is, the free end of the first rubber strip portion 152 is bent or inclined outwardly of the door 100 of the container, so that the water blocking performance of the first rubber strip portion 152 can be improved. In other words, the root end 181d of the first rubber strip portion 152 is connected to the base portion 151, the tip end 181e of the first rubber strip portion 152 is located at one end of the second rubber strip portion 153 away from the base portion 151, and the tip end 181e of the second rubber strip portion 153 is closer to the inner side of the sealing rubber strip 150 than the root end 181d in the first direction D1. Moreover, usually, the door 100 of the container moves outward relative to the container body to open and moves inward to close. Thus, during the closing process of the door 100 of the container, the contact area between the first rubber strip portion 152 and the outer surface of the door frame 170 gradually increases, which is more conducive to improving the sealing performance between the door 100 and the door frame 170, and further improving the waterproof performance of the container.

[0128] Refer to Figure 12 , Figure 16 and Figure 17 , further, an extension portion 154 is formed on the portion of the base portion 151 corresponding to the first rubber strip portion 152 and extends in a direction intersecting the first direction D1 and away from the first rubber strip portion 152. The extension portion 154 continuously extends in a circle along the circumferential direction of the sealing rubber strip 150 in the sealing rubber strip 150. The extension portion 154 is located outside the panel portion 111. The door 100 of the container may further include a second sealing portion. The second sealing portion is connected between the extension portion 154 and the panel portion 111 and continuously extends in a circle along the circumferential direction of the sealing rubber strip 150. The second sealing portion is used to seal the gap between the extension portion 154 and the panel portion 111, so as to block the infiltration of water from the outside of the door 100 prior to the connection structure between the base portion 151 and the outer peripheral side portion of the first plate member 110, and further improve the sealing and waterproof performance of the connection portion between the sealing rubber strip 150 and the door panel.

[0129] Optionally, in a state where the sealing strip 150 is not installed on the door panel, the extending portion 154 has opposite root ends 181d and tip ends 181e. The root end 181d of the extending portion 154 is connected to the base portion 151. The sealing strip 150 has an inner side and an outer side opposite to each other in the first direction D1. The tip end 181e of the extending portion 154 is closer to the inner side of the sealing strip 150 than the root end 181d. In a state where the sealing strip 150 is installed on the door panel, the tip end 181e of the extending portion 154 abuts against the outer surface of the panel portion 111, and a sealing cavity is defined between the extending portion 154 and the panel portion 111. The sealing cavity is adapted to accommodate a second sealing portion. The second sealing portion may be, for example, sealant. Thus, the tip end 181e of the extending portion 154 abuts against the panel portion 111, and the second sealing portion connects the extending portion 154 and the panel portion 111, thereby further improving the sealing reliability and sealing effect between the extending portion 154 and the panel portion 111.

[0130] In Figure 12 , Figure 16 and Figure 17 In the illustrated example, the first rubber strip portion 152 may adopt a structural form of a C-shaped sealing strip 150 similar to a "C" shape in the related art. The second rubber strip portion 153 may adopt a structural form of a J-shaped sealing strip 150 similar to a "J" shape in the related art. In one sealing strip 150, the number of the first rubber strip portions 152 is one, the number of the second rubber strip portions 153 is two, and the second rubber strip portions 153 are located inside the first rubber strip portion 152. The main function of the first rubber strip portion 152 is to block water and reduce water pressure. The second rubber strip portion 153 mainly functions as a seal.

[0131] According to the door 100 of the present embodiment, by providing the sealing strip 150 to include a first rubber strip portion 152 and at least two second rubber strip portions 153 arranged at intervals, the door 100 can still have a relatively large sealing redundancy after the box body is distorted and deformed. At the same time, by using a complete circle of sealant to seal at the joint between the sealing strip 150 and the outer surface of the panel portion 111, compared with the method of only applying sealant locally at the lower joint and the left and right side joints of the sealing strip 150 of the door 100 of a marine container, its waterproof integrity is better. At the same time, the sealing strip 150 is provided with at least two glue grooves for applying sealant, so that at least two seals can be applied to the side contact surface between the sealing strip 150 and the door panel, improving the sealing redundancy. Finally, the door seal pressing strip for fixing the sealing strip 150 and the nail head of the rivet are caulked to prevent water from entering the door panel.

[0132] In some other embodiments, the first rubber strip portion 152 and the second rubber strip portion 153 may be separately connected to different base portions 151. That is, different forms of sealing strips such as a sealing strip having the first rubber strip portion 152 and another sealing strip having the second rubber strip portion 153 are combined and used to achieve sealing.

[0133] In the related art, the edge of the hinge seat 181 of the standard marine container is relatively close to the door opening of the door frame 170. After the hinge assembly 180 is positioned according to the required dimensions, the weld between the hinge seat 181 and the door frame 170 is adjacent to the sealing strip 150. The hinge seat 181 is usually fixed to the door frame 170 by welding. Once the hinge seat 181 is close to the door gap due to positioning deviation or the weld bead is too thick, the sealing strip 150 will be lifted and unable to closely adhere to the door frame 170, resulting in water leakage.

[0134] Refer to Figure 1 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 16 and Figure 17 , according to some embodiments of the present application, the door 100 of the container may further include a hinge assembly 180. The hinge assembly 180 may include a door hinge 182 and a hinge seat 181. The door hinge 182 is connected to the first plate member 110. The hinge seat 181 is adapted to be connected to the door frame 170. The hinge seat 181 is connected to the door hinge 182. The hinge seat 181 has opposite inner edge portions 181a and outer edge portions 181b. In the installed state where the hinge seat 181 is installed on the container, the inner edge portion 181a is closer to the inner peripheral surface of the door frame 170 than the outer edge portion 181b. An avoidance space 181c is formed in the inner edge portion 181a of the hinge seat 181, and the avoidance space 181c is used to avoid the first rubber strip portion 152. By providing the avoidance space 181c in the inner edge portion 181a of the hinge seat 181 here, it is possible to reduce or avoid the interference between the first rubber strip portion 152 and the hinge seat 181 in the installed state where the door 100 is installed on the container body, thereby ensuring the sealing reliability of the first rubber strip portion 152.

[0135] Refer to Figure 12 、 Figure 13 、 Figure 16 and Figure 17, in the related art, the root end 181d of the hinge seat 181 is more likely to interfere with the first rubber strip portion 152. Optionally, the root end 181d of the hinge seat 181 is adapted to be connected to the door frame 170 and protrudes from the outer surface of the door frame 170. The door hinge 182 is rotatably connected to the distal end 181e of the hinge seat 181. The avoidance space 181c is correspondingly provided at the root end 181d of the hinge seat 181. This can further reduce the probability of interference between the hinge seat 181 and the first rubber strip portion 152. Among them, in the state where the hinge seat 181 is installed on the door frame 170, the root end 181d of the hinge seat 181 is farther from the door opening formed in the door frame 170 than the distal end 181e in the width direction of the door frame 170. When the door frame 170 is installed at the end of the container, the width direction of the door frame 170 is parallel to the width direction of the container. When the door frame 170 is installed on the side of the container, the width direction of the door frame 170 is parallel to the length direction of the container.

[0136] Optionally, in the state where the hinge seat 181 is installed on the door frame 170, the extending direction of the hinge seat 181 can be inclined to the plane where the door frame 170 is located. That is, the hinge seat 181 can be in an inclined form in the installed state. Preferably, the extending direction of the hinge seat 181 is perpendicular to the height direction of the door frame 170. The extending direction of the hinge seat 181 can be understood as the direction of the connection line between the geometric center of the root end 181d of the hinge seat 181 and the geometric center of the distal end 181e. The geometric center of the distal end 181e is, for example, the center line of the hinge hole or the axis of the hinge shaft 183 (as Figure 13 shown).

[0137] In other examples not shown, the shape and structure of the hinge seat 181 can also be other deformed forms. For example, the overall outer contour of the hinge seat 181 can be in the shape of an "L", an arc, etc.

[0138] For the door 100 according to the embodiment of the present application, by providing the avoidance space 181c on the hinge seat 181, the distance between the hinge seat 181 and the door gap can be increased, avoiding the end of the sealing rubber strip 150 from being lifted by the weld bead or the hinge seat 181 itself, so as to ensure that the end of the sealing rubber strip 150 can fit tightly with the door frame 170 and reduce the possibility of water ingress.

[0139] Referring to Figures 1 to 17 , some embodiments of the present application also provide a container (not shown). The container may include a door frame 170 and the above-mentioned door 100. The door 100 is rotatably connected to the door frame 170.

[0140] For the container according to the embodiment of the present application, by applying the above-mentioned door 100, the risk of water seepage inside the door 100 can be effectively reduced, thereby improving the waterproof ability of the container.

[0141] Refer to Figure 1 , Figure 11 , Figure 12 , Figure 13 , Figure 16 and Figure 17 , optionally, the door 100 of the container includes the sealing strip 150 in the above embodiments. The sealing strip 150 is continuously provided on the outer peripheral side of the first plate member 110. The sealing strip 150 includes a first strip portion 152. The free end of the first strip portion 152 contacts the outer surface of the door frame 170. The container includes a hinge assembly 180. The hinge assembly 180 includes a door hinge 182 and a hinge seat 181. The door hinge 182 is connected to the first plate member 110. The hinge seat 181 is fixed to the door frame 170. The hinge seat 181 is connected to the door hinge 182. The hinge seat 181 has opposite inner edge portions 181a and outer edge portions 181b. The inner edge portion 181a is closer to the inner peripheral surface of the door frame 170 than the outer edge portion 181b. An avoidance space 181c is formed in the inner edge portion 181a of the hinge seat 181. The avoidance space 181c is used to avoid the first strip portion 152. By providing the avoidance space 181c in the inner edge portion 181a of the hinge seat 181, interference between the first strip portion 152 and the hinge seat 181 can be reduced or avoided in the installation state where the door 100 of the container is installed on the container body, thereby ensuring the sealing reliability of the first strip portion 152.

[0142] Refer to Figure 12 , Figure 13 , Figure 16 and Figure 17 , optionally, the hinge seat 181 has a root end 181d and a tip end 181e spaced along the inner and outer directions of the door frame 170. The root end 181d of the hinge seat 181 is connected to the door frame 170. The door hinge 182 is rotatably connected to the tip end 181e of the hinge seat 181. The avoidance space 181c is correspondingly provided at the root end 181d of the hinge seat 181. The root end 181d of the hinge seat 181 in the related art is more likely to interfere with the first strip portion 152. By correspondingly arranging the avoidance space 181c at the root end 181d of the hinge seat 181, the probability of interference between the hinge seat 181 and the first strip portion 152 can be further reduced.
