A container is a cluster tool for loading and transporting goods and facilitating handling by mechanical means. Containers have formed a whole set of standardized systems. Container standardization can not only improve the versatility and interchangeability of containers as co-transportation units in sea, land, and air transportation, but also improve the security and economy of container transportation. The container standard is divided into four types according to the application range, namely international standard, national standard, regional standard and company standard. The current national standard of external dimension and rated weight of containers (GB 1413-2008) in China stipulates the external dimension, limit deviation and rated weight of containers of various models. Therefore, when the external size meets the national standard, the maximization of the internal space of the container is realized, and more goods can be loaded, so that the space utilization rate of the container is improved. At present, there are two main ways to increase the internal space of the container. On the one hand, on the premise of meeting the strength requirement of the container, the thicknesses of the bottom plate, the top plate and the side plates are reduced, so that the length, the width and the height of the inner space are increased, and the inner volume of the container is larger. On the other hand, the assembly mode of each component of the container is optimized, unnecessary space occupation is reduced, and therefore the space utilization rate of the container is improved.

The container is provided with an end door or a side door, so that goods can be loaded and unloaded conveniently. The end door sets up in the front end portion or the rear end portion of container box, and the side door sets up the side at the container box. The end door and the side door are connected to the container body through hinges to realize rotatable connection. One end of the hinge is fixed on the box body frame, and the other end of the hinge is fixed on the container door and realizes rotation through the rotating shaft. At least part of the existing hinge protrudes out of the door of the container, and occupies the space in the width direction of the container, so that the internal space of the container is reduced, and the space utilization rate of the container is reduced. Therefore, the inventor researches on the existing container to find that the arrangement of the concave part on the surface of the container door for accommodating at least part of the hinge can reduce the occupation of the hinge on the width space of the container, thereby improving the space utilization rate of the container.

The application discloses a container, this kind of container can be used to warehouse storage goods, also can be used to the field of transportation goods such as land transportation, sea transportation.

The insulating cover plate 24 is the portion of the door panel assembly 2 that is in contact with the interior environment of the container, i.e., the inner shell of the door panel assembly 2. The material of the thermal cover 24 may be the same as or different from that of the door 22. The insulation cover 24 may be made of a light aluminum material in view of reducing the weight of the container. The inside of heat preservation cover plate 24 is equipped with at least one parting bead, is convenient for install heat preservation 23, prevents simultaneously that heat preservation 23 from sinking to the bottom of door plant subassembly 2 because of the effect of gravity, influencing heat retaining homogeneity. The number of the division bars is set according to the size of the actual heat insulation cover plate 24 and the requirement of heat insulation performance, and the embodiment does not limit the number. The two ends of the division bar are welded or bonded on the side edge of the heat-insulating cover plate 24. The distance between two adjacent parting strips can be kept consistent, and the processing and the manufacturing are convenient. The thermal insulation cover plate 24 covers at least part of the door panel 22, and is convenient to process simultaneously for realizing better thermal insulation performance, the length of the thermal insulation cover plate 24 is slightly smaller than the difference value between the length of the door panel 22 and the length of the first concave part 21, the width of the thermal insulation cover plate 24 is slightly smaller than the width of the door panel 22, and the height of the thermal insulation cover plate 24 is equal to that of the door panel 22, so that the thermal insulation cover plate 24 can be nested in the door panel 22. It should be noted that the thickness of the door panel 22 is the thickness of the door panel assembly 2, since the insulating cover panel 24 is nested within the door panel 22.

The heat preservation piece 23 is a part in the middle of the door panel assembly 2, one large surface of the heat preservation piece 23 is attached to the inner surface of the door panel 22, and the other large surface of the heat preservation piece 23 is attached to the outer surface of the heat preservation cover plate 24. The insulating member 23 may be made of insulating cotton. The heat-insulating cotton is a non-toxic, harmless and pollution-free heat-insulating material prepared from high-purity clay clinker, alumina powder, silica powder, loxying sand and the like. The heat insulating cotton can be further processed into products such as fiber blankets, boards, paper, ropes and the like. The adaptive temperature of the heat insulation cotton is between 44 ℃ below zero and 100 ℃. The heat-insulating member 23 may be a heat-insulating plate made of rock wool because of the environmental protection property of the heat-insulating cotton. The rock wool heat-insulating board is a product prepared by using basalt and other natural ores as main raw materials, adding a certain amount of binder, dustproof oil and water repellent for assistance, and carrying out processes such as sedimentation, solidification, cutting and the like. The production process of the rock wool insulation board is energy-saving and environment-friendly, and belongs to a green, environment-friendly, novel and energy-saving building material. It should be noted that the heat insulation member 23 may also be a heat insulation plate made of traditional quartz sand, which is not limited in this embodiment.

The insulating cover plate 24 is installed on the inner surface of the door panel 22 and is butted with the door panel 22, namely, the insulating cover plate 24 is nested in the door panel 22. The cavity between the insulating cover plate 24 and the door plate 22 is filled with an insulating member 23. The specific assembling process can be selected such that the heat preservation member 23 is firstly made into a plate shape and is filled in the heat preservation cover plate 24, and at the moment, the division bar plays a limiting role in each heat preservation member 23. After the insulating member 23 is assembled in the insulating cover plate 24, the insulating cover plate 24 is welded to the inner side of the door panel 22, thereby forming the door panel assembly 2. It should be noted that the insulating cover plate 24 may also be fixedly connected to the door panel 22 by other methods, and the assembly method of the door panel assembly 2 may also adopt other methods, which is not limited in this embodiment.

According to the embodiment of the application, the door panel assembly 2 has a sandwich structure, and the heat preservation piece 23 filled in the middle interlayer realizes good heat preservation performance. When the external temperature is lower than the internal temperature of the container, the heat-insulating piece 23 can prevent the gas in the container from condensing to form water vapor, so that the service life of the container is prolonged; when the outside temperature is higher than the inside temperature of the container, the inside temperature of the container can be prevented from rising, thereby avoiding damage to goods stored in the container or parts of the container.

Referring to fig. 4, equipotential screws 25 are arranged on the heat-insulating cover plate 24. When the door panel assembly 2 is in a closed state, the equipotential screw 25 compresses the box body frame 1, so that the door panel assembly 2 and the box body frame 1 are equipotential.

The equipotential screw 25 is a screw-like member having an equipotential function. One end of the equipotential screw 25 is welded on the inner surface of the heat-insulating cover plate 24, and the number of the equipotential screws 25 is set according to the practical application condition. When the door panel component 2 is in a closed state, the other end of the equipotential screw 25 is pressed against the box body frame 1. The principle of equipotential is to connect the exposed metal and conductive part of each electrical device and other devices with artificial or natural grounding body through conductors to realize equipotential between the electrical device or the leaked metal and human body and prevent electric shock. Specifically, when the door panel assembly 2 of the container is in the closed state, if the door panel assembly 2 leaks electricity, the current is transmitted to the heat-insulating cover plate 24 and then transmitted to the box frame 1 through the equipotential screw 25, and at this time, the potential of the door panel assembly 2 is equal to that of the box frame 1, and no potential difference exists. Therefore, electric shock does not occur when a person touches the door panel assembly 2. On the other hand, if the electric leakage occurs in the electric device inside the container, the current is transmitted to the box frame 1 and then transmitted to the door panel assembly 2 through the equipotential screw 25, and at this time, the door panel assembly 2 and the box frame 1 have the same potential and no potential difference, so that electric shock does not occur.

According to an embodiment of the application, the insulating cover plate 24 is provided with equipotential screws 25. When the door panel component 2 is in a closed state, the equipotential screws 25 compress the box body frame 1, so that the potential between the door panel component 2 and the box body frame 1 is equal, and electric shock is prevented.

Referring to fig. 2 and 3, the outer surface of the door panel assembly 2 is also provided with a second recess 26. The second recess 26 is disposed on a side of the door panel assembly 2 away from the rotation axis. The second recess 26 is provided with at least one through hole 27.

The second recess 26 is a receiving portion formed by recessing an edge of the outer surface of the door panel assembly 2 inward. The recess depth of the second recess 26 (i.e. the width of the second recess 26) is smaller than the width of the door panel assembly 2, and the specific width may be set according to the practical application, which is not limited in the embodiment of the present application. In consideration of convenience of processing and manufacturing, the recess depth of the second recess 26 may be the same as the recess depth of the first recess 21, the length of the second recess 26 may be the same as the length of the first recess 21, and the shape of the second recess 26 may be the same as the shape of the first recess 21.

The phrase "the second concave portion 26 is disposed on the side of the door panel assembly 2 away from the rotation axis" means that the second concave portion 26 is disposed on both sides of the door panel assembly 2 opposite to the first concave portion 21.

The through hole 27 is a hole penetrating the door panel assembly 2 in the width direction of the container. The shape of the through hole 27 may be circular or square, etc. The location and number of through holes 27 is not limited in this embodiment.

According to an embodiment of the present application, the outer surface of the door panel assembly 2 is further provided with a second recess 26. By providing the second recess 26, other components can be mounted at a position relative to the first recess 21, improving flexibility of component mounting positions. And the other parts are accommodated in the second concave part 26, so that the occupation of the width space of the container is reduced, and the energy density of the container is improved.
