Description

Technical Field

[0001] The present invention relates to the field of container accessories, and in particular to a desiccant hanging device for a container. Background Art

[0002] Since the 19th century, globalization has continued to deepen and develop, and accordingly, a global logistics system has been formed. Containers were also born, and today they have become an indispensable part of the logistics system. The greatest success of containers lies in their standardization and the entire transportation system that has been established. This has enabled the standardization of a behemoth with a load capacity of dozens of tons, and has gradually established a global logistics system that supports ships, ports, shipping routes, roads, transfer stations, bridges, tunnels, and multimodal transport. Container transportation uses large containers as carriers to assemble goods into unitized units. This allows large-scale loading and unloading machinery and large-scale transport vehicles to carry out loading, unloading, handling, and transportation tasks in the modern circulation field, thereby better realizing the "door-to-door" transportation of goods. It is a new, efficient, and cost-effective transportation method. It has advantages that are difficult to replace by other means: it ensures the safety of cargo transportation. Container transportation greatly reduces the number of manual loading, unloading and handling operations in traditional transportation methods. This can avoid cargo damage, moisture damage, loss and other freight accidents caused by human and natural factors, reducing economic losses; it saves cargo packaging materials. Using container transportation can simplify or eliminate transportation packaging, saving packaging materials and costs, and reducing the cost of goods; it simplifies freight operation procedures. After cargo is transported in containers, the box is used as the transportation unit of cargo, reducing complex operation links and simplifying freight operation procedures; it improves loading and unloading efficiency. Since container loading and unloading operations are suitable for mechanization, its loading and unloading efficiency has been greatly improved. At the same time, it greatly shortens the container's stay time at the station (port), speeding up the turnover of vehicles and ships and the delivery of cargo; it reduces operating expenses and transportation costs, greatly reducing cargo damage and loss, and cargo insurance premiums; after the development of "door-to-door" transportation services, it can significantly save warehouse construction costs and warehouse operation costs; it facilitates automated management. Containers are standardized cargo transportation units, which creates convenient conditions for automated management.

[0003] When engaging in import and export trade, it is necessary to ensure a dry environment inside the container, especially for goods that have high requirements for environmental dryness and humidity, such as precision instruments, crops, and some special raw materials.

[0004] During ocean transportation or storage, containers often experience high temperatures and significant diurnal temperature swings. Temperatures can fluctuate between 0 and 8 degrees Celsius, and humidity can reach as high as 98%. This is known as condensation. At 30 degrees Celsius, the water content in the air is 30.4 grams per square meter. When the temperature drops from 30 degrees Celsius to 18 degrees Celsius, water vapor condenses into droplets. In a 40-foot container, this can produce 1,000 grams of condensed water, creating "container rain." Humidity or moisture is introduced into the container along with the cargo. The humidity / moisture content in cargo depends on the product type and the relative humidity of the surrounding air at the time of loading. Naturally, relative humidity in tropical regions is much higher than in temperate regions. Therefore, when cargo is loaded into the container, it also introduces moisture or water vapor. For example, if a container contains 5 tons of furniture, the furniture itself will contain approximately 8% to 25% humidity, depending on the wood type and the degree of drying. This is equivalent to approximately 400-1,250 liters of water. Some of this moisture will escape into the air inside the container, becoming a significant source of condensation. A 20-foot container has a volume of approximately 33 cubic meters. One cubic meter of subtropical air at 90% relative humidity contains 33 grams of water at 32°C, which amounts to 1.3 liters of water. (At the same temperature, one cubic meter of air at 55% relative humidity contains 28 grams of water. In contrast, one cubic meter of European air at 100% relative humidity and 0°C contains only 5 grams of water, or a total of 0.2 liters of water. At 55% relative humidity, there are 3 grams of water per cubic meter.) Once the air temperature outside the container drops, 1.2 liters of water will condense on the inner walls of the container or on the surfaces of other items inside.

[0005] If the container is not dry, these water droplets may drip directly onto the goods, causing damage to the goods. Therefore, a dry environment is required. In addition, if it is very humid during transportation, bacteria may grow inside, and it may also cause mold. In the process of international trade, the management of rotten and moldy things is particularly strict. If the goods are found to be moldy and rotten during port inspection, they may be highly suspected of carrying epidemic bacteria. Such goods may be prohibited from entering the port, which may cause losses to merchants. Therefore, the container must be very dry. When opening the container for inspection, no unnecessary risks may be caused by the smell of mold due to humidity inside.

[0006] The standard heights of shipping containers are 2.393m and 2.698m. Multiple hanging rings are installed on the top of the inner wall of the container. One way to install desiccant in the container is to hang it on the inner wall of the container via hooks. Since the hanging height exceeds the maximum reach of a human body when standing naturally, when hanging the container desiccant from the hanging ring on the inner wall of the container, the existing operation method is to use objects such as stools or ladders to increase the reach height for hanging. This poses certain personal risks to the operator, and the operation steps are cumbersome and time-consuming.

[0007] like Figure 1 The schematic diagram of the structure of a conventional container hook is shown. The hook opening is oblique, typically set at a 45-degree angle, and a locking block 200 is provided inside the hook to facilitate securing the hook to the hanging ring. Containers are inevitably subject to shaking and bumping during transportation, so the hook must have a certain degree of tightness to prevent the hook from detaching from the hanging ring during bumps, causing the desiccant to fall. However, the more firmly the hook is attached to the hanging ring, the more difficult it is to remove the desiccant. Cost constraints also dictate that the hook must have a simple structure and be made of inexpensive materials.

[0008] In addition, existing desiccant is often packed in the form of powder bags in non-woven bags, which are then fixed to hooks using rivets and other components. This process is relatively complex and has low operating efficiency. In addition, the added third-party items such as rivets are easily corroded by the shipping environment of the container, resulting in quality problems.

[0009] Therefore existing technology still needs to be improved and improved. Summary of the Invention

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] It should be noted that when a component is referred to as being “mounted on,” “fixed on,” or “disposed on” another component, it may be directly on the other component or there may be an intermediate component. When a component is referred to as being “connected to” another component, it may be directly connected to the other component or there may be an intermediate component.

[0032] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0033] like Figure 2 、 Figure 3 and Figure 6As shown, the present invention provides a desiccant hanging device for a container, including a hanging rack 10 for carrying a desiccant, the hanging rack 10 is provided with a hook portion 20 and a top support portion 30 for cooperating with an external support rod to support the desiccant hanging device for a container, the hook portion 20 includes an upper hook portion 21 and a lower hook portion 22, the opening of the upper hook portion 21 is downward and tilted forward at a preset angle, the lower hook portion 22 is elastic, located directly below the upper hook portion 21, and its opening is upward, there is a gap between the lower hook portion 22 and the upper hook portion 21, and the top end of the lower hook portion 22 is higher than the opening of the upper hook portion 21, when the lower hook portion 22 contacts the inner wall of the container, the lower hook portion 22 is deformed and forms a closed loop (closed structure) with the upper hook portion 21. When the present invention is hung, the staff supports the hanging device on the top support part 30 through the support rod to send it to a high place, and the hanging ring slides from the gap between the upper hook part 21 and the lower hook part 22 from top to bottom along the lower hook part 22 to below the opening of the upper hook part 21. Then the staff can retract the support rod, and the hanging device falls under the action of gravity, so that the upper hook part 21 is completely hooked on the hanging ring. At the same time, since the upper hook part 21 is tilted forward, the hanging rack 10 will always have a potential energy to push forward under the action of gravity, so that the desiccant hung on the hanging rack 10 will naturally The lower hook 22 will be tightly pressed against the inner wall of the container. Not only that, the lower hook 22 will resist the inner wall of the container and deform, closing the opening of the upper hook 21 to form a closed loop. In this way, even in a bumpy environment, the hook will not fall off the hanging ring, and the hanging is firm and stable. Moreover, the present invention also ensures that the hanging and removing operations of the hanging device are simplified and convenient, avoiding the need for staff to stand on a stool to manually remove the desiccant, and there will be no situation where the desiccant is too tight and difficult to remove. The staff only needs to support and retract the product of the present invention to complete the hanging / removal work, which is simple and convenient, saving time and effort.

[0034] Preferably, the desiccant hanging device for a container provided by the present invention has a strip hole 40 for hanging the desiccant on the hanging rack 10, the top support portion 30 is located on the back side of the hook portion 20, and the strip hole 40 is located below the top support portion 30 and the hook portion 20. More specifically, the strip hole 40 is located at the center between the top support portion 30 and the hook portion 20. In the present invention, the hook portion 20 is perpendicular to the hanging rack 10. Furthermore, the hook portion 20 is arranged perpendicular to the strip hole 40. The present invention is mainly used for hanging serially connected long strips of desiccant (desiccant produced by packaging multiple powder bags in a row). When installing the desiccant, it is only necessary to pass half of the long strip of desiccant through the strip hole 40, fold it in half, and then put a non-woven bag on the outside to tightly fasten the desiccant to the hanging rack 10. Compared with the existing method of fixing with rivets, the operation is simpler and does not require the use of other parts for installation, saving costs.

[0035] Better, such as Figure 4 As shown, the desiccant hanging device for a container provided by the present invention has a bottom surface 41 of the strip hole 40 in an upwardly convex arc shape, which can cause the long strip of desiccant hung on the hanging rack 10 and the packaging near the bottom surface 41 of the strip hole 40 to produce slight deformation, thereby achieving the effect of preventing the desiccant from sliding due to shaking after installation. In addition, this design does not excessively affect the smoothness of the long strip of desiccant passing through the strip hole 40, further ensuring the convenience of operation for the staff.

[0036] Furthermore, in the desiccant hanging device for a container provided by the present invention, the preset forward tilt angle of the upper hook portion 21 is between 10 and 40 degrees. Preferably, in the desiccant hanging device for a container provided in this embodiment, the preset forward tilt angle of the upper hook portion 21 is 15 degrees.

[0037] like Figure 5 As shown, specifically, in the desiccant hanging device for a container provided by the present invention, the top support portion 30 is a wedge-shaped groove opening downward.

[0038] Furthermore, in the desiccant hanging device for a container provided by the present invention, the strip-shaped hole 40 is located below the top support portion 30 and the hook portion 20 to further ensure easy hanging and taking operations.

[0039] Furthermore, in the desiccant hanging device for a container provided by the present invention, the strip-shaped holes 40 are multiple and evenly and symmetrically arranged on the hanging rack 10. In another preferred embodiment of the present invention, the strip-shaped holes 40 are three and evenly and symmetrically arranged on the hanging rack 10. In this way, the hanging device can hang multiple desiccants at the same time, which is conducive to further reducing the workload of the staff.

[0040] Furthermore, in the desiccant hanging device for a container provided by the present invention, the hanging frame 10, the hook portion 20 and the top support portion 30 are integrally formed, generally using plastic integral molding, and the lower hook portion 22 is generally designed to be thinner (thinner) to have sufficient elastic deformation capacity.

[0041] In summary, when the present invention is hung, the staff supports the hanging device on the top support part through the support rod to a high place, and the hanging ring slides from top to bottom along the lower hook from the gap between the upper hook part and the lower hook part to below the opening of the upper hook part. Then the staff can retract the support rod, and the hanging device falls under the action of gravity, so that the upper hook part is completely hooked on the hanging ring. At the same time, since the upper hook part is tilted forward, the hanging rack will always have a potential energy to push forward under the action of gravity, so that the desiccant hung on the hanging rack will naturally be close to the collection rack. On the inner wall of the box, not only that, the lower hook will resist the inner wall of the container and deform, closing the opening of the upper hook to form a closed loop. In this way, even in a bumpy environment, the hook will not fall off the hanging ring, and the hanging is firm and stable. Moreover, the present invention also ensures that the hanging and taking operations of the hanging device are simplified and convenient, avoiding the need for staff to stand on a stool to manually pick up the desiccant, and there will be no situation where the desiccant is too tight and difficult to remove. The staff only needs to support and retract the product of the present invention to complete the hanging / removal work, which is simple and convenient, saving time and effort.

[0042] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the claims attached to the present invention.
