A placement plate is fixed inside the thermal insulation box body. An adjustment plate is installed inside the thermal insulation box body, and the adjustment plate is located above the placement plate. Placement grooves for placing drugs are provided on both the placement plate and the adjustment plate. An installation structure is provided between the adjustment plate and the thermal insulation box body; when there are more drugs, the adjustment plate is taken out and installed inside the thermal insulation box body by cooperating with the installation structure, and then the drugs are sequentially placed in the placement grooves on the adjustment plate.

[0004] Through the cooperation of the adjustment plate and the installation structure, this thermal insulation box can layer the space inside the thermal insulation box body, facilitating the placement of more drugs, improving the space utilization rate inside the thermal insulation box body, reducing the accumulation and extrusion between drugs, and reducing the collision between drugs during transportation. However, the layering of this thermal insulation box is along the horizontal direction. Cold storage materials will be stored in the thermal insulation box. If the cold storage materials are placed at the bottom of the box, it is easy to cause the cooling effect of the drugs in the upper layer to decline; if the cold storage materials are placed in each layer, it is easy for the cold storage materials to be crushed and damage the drugs.

Detailed Implementation Modes

[0025] The following combines the attached Figures 1 - 6The embodiments of the present utility model will be described with reference to related embodiments. The embodiments of the present utility model are not limited to the following embodiments, and the relevant necessary components of the present utility model in the technical field should be regarded as well-known technologies in the technical field and can be known and mastered by those skilled in the technical field.

[0026] The present utility model provides a heat-insulating box for the constant-temperature cold-chain transportation of drugs. As Figure 1 shown, it includes a box body 1 and a box cover 2. The box cover 2 is arranged above the box body 1 and fits with the box body 1. As Figure 2 and Figure 3 shown, a heat-insulating cavity 11 for accommodating drugs is arranged in the box body 1. A downwardly protruding cover plate 21 is arranged on the lower surface of the box cover 2. A sealing ring 3 and a sealing strip 4 are arranged between the cover plate 21 and the heat-insulating cavity 11.

[0027] As Figure 5 shown, a detachable spacer 13 and a grid are arranged in the heat-insulating cavity 11. The two ends of the spacer 13 along its own length direction are in contact with the side walls of the heat-insulating cavity 11. The spacer 13 divides the heat-insulating cavity 11 into two inner cavities 16. Raised blocks 15 are respectively arranged at the bottom edge of the spacer 13 and the bottom edge of the heat-insulating cavity 11. The grid is arranged above the raised blocks 15, and a refrigerant storage cavity is arranged between the grid and the heat-insulating cavity 11.

[0028] In the present utility model, a grid is arranged at the bottom of the heat-insulating cavity 11, and a refrigerant storage cavity is arranged between the grid and the heat-insulating cavity 11. The cold storage material is placed in the refrigerant storage cavity and will not crush and damage the drugs. At the same time, a detachable spacer 13 and a grid are arranged in the heat-insulating cavity 11. The spacer 13 can divide the heat-insulating cavity 11 into two inner cavities 16 in the vertical direction, so that the drugs are stored separately to avoid stacking of drugs. There is cold storage material below each inner cavity 16 for storing drugs, so that each space for storing drugs has a good constant-temperature effect.

[0029] The detachable property of the spacer 13 and the adjustable property of the grid enable this design to adapt to the storage requirements of drugs with different volumes and shapes, improve the utilization rate of the storage space, and ensure that drugs of different sizes can obtain a good constant-temperature effect. At the same time, the present utility model adopts the combination of the sealing ring 3 and the sealing strip 4, and a good sealing effect can be achieved between the box body 1 and the box cover 2 whether the spacer 13 is disassembled or not.

[0030] More specifically, the heat-insulating box for drug cold chain needs to have the following performances.

[0031] 1) Heat-insulating performance: The heat-insulating box adopts high-efficiency heat-insulating materials, such as polyurethane foam, vacuum heat-insulating layer, etc., to ensure that the temperature inside the box is stable and can usually be maintained within the range of 2 - 8 °C to meet the storage and transportation requirements of most drugs.

[0032] 2) Sealing performance: The insulation box adopts the combined design of the sealing ring 3 and the sealing strip 4 to ensure a tight fit between the box body 1 and the box cover 2, preventing the intrusion of external air and moisture, thereby maintaining the stability and consistency of the environment inside the box.

[0033] 3) Cold storage materials: Cold storage materials such as ice packs and ice crystals are stored. These cold storage materials can stably release or absorb cold energy to provide a continuous constant-temperature environment for the drugs in the insulation cavity 11.

[0034] During the transportation of the insulation box, the cold storage materials will occupy some space inside the insulation box, which may limit the stacking quantity and method of the drugs. Therefore, when designing and using the insulation box, it is necessary to fully consider the size and quantity of the cold storage materials to ensure that both the temperature control requirements can be met and the space inside the box can be utilized maximally.

[0035] The layout and position of the cold storage materials will affect the temperature distribution inside the insulation box. If the layout is unreasonable, it may cause the temperature in some areas inside the box to be too high or too low, thereby affecting the storage quality of the drugs. Therefore, it is necessary to reasonably layout the cold storage materials according to the characteristics of the drugs and the transportation requirements to ensure a uniform temperature distribution inside the box.

[0036] To address the above problems, the present application is provided with a grid at the bottom end of the insulation cavity 11, and a refrigerant storage cavity is provided between the grid and the insulation cavity 11. The cold storage materials are stored in the refrigerant storage cavity, which not only ensures that the cold storage materials do not directly contact the drugs, preventing the drugs from being damaged due to excessive cold and avoiding the risk of the drugs being damaged due to the backlog of the cold storage materials, but also allows the cold energy to be transmitted to all corners inside the insulation cavity 11 through the grid.

[0037] The position distribution of the cold storage materials is solved, but how to store the drugs reasonably so that the drugs will not be stacked and the temperature distribution in the space where the drugs are located can be ensured to be uniform. The present application proposes a detachable spacer 13. The spacer 13 can divide the insulation cavity 11 into two inner cavities 16 in the vertical direction. This design enables the user to adjust the layout of the storage space according to needs. For drugs that need to be stored separately, the spacer 13 provides an effective means of separation, avoiding the stacking and mutual influence between the drugs.

[0038] At the same time, the user can disassemble the spacer 13 and replace the grid according to the storage requirements of drugs with different volumes and shapes. The detachable nature of the spacer 13 and the adjustability of the grid also enhance the flexibility of the storage space. The user can adjust the position and size of the grid according to the volume and shape of the drugs to ensure that the drugs can be placed stably in the insulation cavity 11 and make full use of the storage space.

[0039] Below each inner cavity 16 for storing medicines, there is a cold storage material provided. This design ensures that a uniform cold quantity supply can be obtained for each space storing medicines. Thus, no matter where the medicines are located in the heat preservation cavity 11, a good constant temperature effect can be enjoyed.

[0040] A sealing ring 3 and a sealing strip 4 are provided between the cover plate 21 and the heat preservation cavity 11. With the design combining the sealing ring 3 and the sealing strip 4, whether the spacer 13 is disassembled or not, a good sealing effect can be maintained between the box body 1 and the box cover 2. This design effectively prevents the intrusion of external air and moisture, thereby ensuring the stability and consistency of the constant temperature environment in the heat preservation cavity 11.

[0041] As Figure 5 shown in Figure 6 the figure, the grid is divided into a first grid 141 and a second grid 142, and the refrigerant storage cavity is divided into a first refrigerant storage cavity 171 and a second refrigerant storage cavity 172. The grid is replaced according to the usage situation of whether the spacer 13 is disassembled, and corresponding refrigerant storage cavities are formed.

[0042] As one of the preferred embodiments of the present utility model, as Figure 3 shown in Figure 5 the figure, a placement groove 5 is provided at the top edge of the inner cavity 16. There are two cover plates 21, and the sizes of the two cover plates 21 match the size of the inner cavity 16. A sealing ring 3 matching the placement groove 5 is provided on the outer side of the cover plate 21. The cover plate 21 is arranged at the top of the inner cavity 16 and the sealing ring 3 is arranged in the placement groove 5. The cover plate 21 forms a sealed connection with the inner cavity 16 through the sealing ring 3.

[0043] When the spacer 13 is arranged in the heat preservation cavity 11, two smaller inner cavities 16 are formed. At this time, it is suitable for storing medicines with smaller volumes. Each inner cavity 16 is provided with a first grid 141, and the size of the first grid 141 matches the size of the inner cavity 16. A first refrigerant storage cavity 171 is formed between the inner cavity 16, the first grid 141 and the spacer 13.

[0044] The cold storage material is placed in the first refrigerant storage cavity 171. The placement groove 5, the cover plate 21 and the sealing ring 3 form a good sealing component, so that the cover plate 21 forms a sealed connection with the inner cavity 16 through the sealing ring 3, ensuring the stable temperature of the inner cavity 16 and preventing quality problems of the medicines caused by improper temperature.

[0045] As one of the preferred embodiments of the present utility model, as Figure 4 shown in Figure 6As shown, the placement groove 5 includes a large arc groove 51 and a small arc groove 52. The large arc groove 51 is arranged at the top edge of the insulation cavity 11, and the small arc groove 52 is arranged at the top edge of the spacer 13. A sealing strip 4 is also arranged at the top edge of the insulation cavity 11. The sealing strip 4 is arranged between the large arc grooves 51. The cover plate 21 forms a sealed connection with the insulation cavity 11 through the sealing ring 3 and the sealing strip 4 when the spacer 13 is removed from the insulation cavity 11.

[0046] The size of the second grid 142 matches the size of the heat preservation chamber 11. When the spacer 13 is removed from the heat preservation chamber 11, the second grid 142 forms a second refrigerant storage chamber 172 with the heat preservation chamber 11. After the spacer 13 is removed, the heat preservation box can accommodate medicines of the size of the heat preservation chamber 11, and the first grid 141 is replaced with the second grid 142, so that the cold storage material can be evenly distributed throughout the bottom of the heat preservation chamber 11.

[0047] Since the small arc groove 52 is arranged on the spacer 13, the sealing ring 3 cannot seal the edge of the entire heat preservation chamber 11, so the sealing strip 4 is proposed. The cooperation between the sealing ring 3 and the sealing strip 4 makes the heat preservation chamber 11 and the box cover 2 form a sealed connection, ensuring that the temperature of the heat preservation chamber 11 is constant after the spacer 13 is removed. The detachability of the spacer 13 and the adjustability of the grid make the design adaptable to the storage requirements of medicines of different volumes and shapes, improve the utilization rate of the storage space, and ensure that medicines of different sizes can obtain a good constant temperature effect.

[0048] As one of the preferred embodiments of the present invention, the spacer 13 is connected to the side wall of the heat preservation chamber 11 through a magnetic structure, and the grid is connected to the raised block 15 through a magnetic structure. The magnetic structure allows the spacer 13 to be quickly fixed to the side wall of the heat preservation chamber 11 without using traditional fasteners such as screws and bolts, saving installation and disassembly time.

[0049] The two ends of the spacer 13 along its own length direction are in contact with the side walls of the insulation chamber 11. The large contact area makes the magnetic attraction and stabilization effect between the spacer 13 and the side walls of the insulation chamber 11 better, and can prevent the insulation box from being bumped by the medicines during transportation, causing the spacer 13 to loosen the connection with the side walls of the insulation chamber 11.

[0050] The grid is connected to the raised block 15 via a magnetic structure, which ensures that the grid can be firmly fixed on the raised block 15 when needed to avoid displacement or falling off during use, and also allows the grid to be easily removed from the raised block 15 for easy replacement.

[0051] As one of the preferred embodiments of the present utility model, a latch 6 is provided between the box body 1 and the box cover 2, and the latch 6 is arranged at opposite ends of the insulation box. The latch 6 of the present application is an ordinary latch 6 for insulation boxes on the market. During transportation or movement, the latch 6 can prevent the box cover 2 from accidentally opening and ensure the safety of the items inside the box. Insertion holes 12 are respectively arranged on opposite sides of the insulation cavity 11, and insertion blocks 22 matching the insertion holes 12 are respectively arranged at opposite ends of the box cover 2. The insertion holes 12 and the insertion blocks 22 play a positioning role, enabling the box cover 2 to accurately align with the box body 1 when closed, facilitating the sealing combination of the cover plate 21 and the insulation cavity 11.

[0052] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
