Description

Technical Field

[0001] This utility model relates to the field of express delivery box technology, specifically a high-efficiency insulated express delivery box with layered mechanical partitions. Background Technology

[0002] With the rapid development of e-commerce and logistics, the demand for items sensitive to transportation temperature, such as fresh food and biopharmaceutical products, has surged. Insulated express boxes have become a key carrier for transporting these items. However, existing insulated express boxes still have significant deficiencies in terms of insulation performance and space adaptability.

[0003] In terms of insulation performance, most insulated express delivery boxes currently have relatively simple insulation designs, with limited choice and performance of insulation materials. Common insulation materials are mostly ordinary polyurethane foam, pearl cotton, or EPS foam. Although these materials are low in cost, they have a high thermal insulation coefficient and can only achieve basic insulation, making it difficult to prevent heat transfer during long-term transportation. Although some express delivery boxes attempt to use multiple insulation materials, they have not formed a scientific insulation structure. The heat exchange between the inside and outside of the box is still relatively frequent, resulting in large temperature fluctuations inside the box. This cannot meet the stringent requirements for temperature stability in the preservation of fresh food and the temperature control of medicines, often leading to problems such as spoilage of goods and reduced efficacy of medicines.

[0004] In terms of space utilization and partition flexibility, most existing insulated express delivery boxes are integrated fixed structures, lacking adjustable partition designs; the few boxes with partitions only use fixed plastic partitions or removable cardboard partitions. The former cannot adjust the space according to the size and quantity of items, while the latter has low strength, is easily damaged, and is difficult to adapt to the storage needs of items of different sizes. When transporting multiple items, the items are prone to shaking and collision inside the box, causing damage; at the same time, the fixed structure leads to low space utilization, often resulting in "large boxes containing small items," wasting transportation space and costs, and failing to meet the diverse needs of transporting goods.

[0005] Therefore, it is necessary to study a high-efficiency insulated express delivery box with layered mechanical partitions. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a high-efficiency insulated express box with layered mechanical partitions. It has the advantages of dual high-efficiency insulation and flexible adjustable layered partitions, and solves the problems of existing insulated express boxes relying on a single ordinary insulation material (such as ordinary polyurethane foam, pearl cotton, etc.), resulting in poor insulation performance, large temperature fluctuations during long-term transportation, lack of flexible partition structure, low space utilization, and easy collision damage to items.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency insulated express box with layered mechanical partitions, comprising a box body and a lid made of high-strength environmentally friendly plastic. Both the box body and lid have internal filling cavities filled with polyurethane foam. Support frames are fixedly connected to the four corners of the inner wall of the box. A vacuum insulation panel is fixedly connected between every two support frames. A snap-fit ​​groove is provided at the center line of the vacuum insulation panels on both the left and right sides. A partition plate is slidably connected inside the snap-fit ​​groove. Sliding grooves are symmetrically provided at the top and bottom of the partition plates. A slider is slidably connected inside the sliding groove. A separator plate is fixedly connected to the outside of the slider. A limit groove is provided on one side of the surface of the separator plate. Limit frames are fixedly connected to the inner sides of the vacuum insulation panels on both the upper and lower sides. A locking bolt is provided inside the limit frame. A locking hole is provided at the bottom of the limit groove, and the locking hole is threadedly connected to the locking bolt.

[0008] As a preferred embodiment of this utility model, the top and bottom of the snap-fit ​​groove are symmetrically provided with positioning grooves, and the two sides of the partition plate are symmetrically provided with positioning holes. An ejector spring is provided inside the positioning hole, and positioning posts are symmetrically fixedly connected to both ends of the ejector spring. The other end of the positioning post passes through the positioning hole and is snapped into the positioning groove.

[0009] As a preferred embodiment of this utility model, the partition plate has a toggle groove on its front side, and the positioning post has a toggle block fixedly connected to its surface, with the toggle block slidably connected to the toggle groove.

[0010] As a preferred embodiment of this utility model, the bottom of the four support frames is fixedly connected to the same buffer pad, and the buffer pad is made of elastic heat-insulating material, with several evenly distributed air holes on the inner side of the buffer pad.

[0011] As a preferred embodiment of this invention, an aluminum foil reflective film is adhered to the inner side of the vacuum insulation panel, and the surface of the aluminum foil reflective film is provided with a corrosion-resistant coating.

[0012] As a preferred embodiment of this utility model, the inner side of the box cover is provided with a sealing protrusion that matches the edge of the box opening, and the sealing protrusion is used in conjunction with the box body. The partition plate and the divider plate are both provided with cavities, and the cavities are filled with thermal insulation cotton. The edges of the partition plate and the divider plate are provided with sealing strips.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses high-strength environmentally friendly plastic as the base for the box body and lid. The polyurethane foam filling the internal cavity and the vacuum insulation board fixed by the support frame form double insulation, reducing heat exchange between the inside and outside of the box and providing a stable temperature environment for fresh food, medicine, etc., thus solving the problem of poor insulation effect of existing express boxes. Then, the partition plate is slidable by the snap-fit ​​groove. The sliding groove and slider drive the partition plate to move. The limit groove, limit frame, locking bolt and locking hole fix the partition plate. The space can be divided as needed to avoid collision of items, improve space utilization, and solve the problems of fixed partitions and inconvenience of use in existing express boxes.

[0014] 2. This utility model uses the elastic force provided by the ejector spring to drive the positioning column to engage with the positioning groove, which can achieve the initial positioning of the partition plate without additional operation, simplifying the operation process of adjusting the position of the partition plate, improving the convenience of use, and the positioning structure is stable and reliable, which can effectively limit the accidental movement of the partition plate.

[0027] refer to Figure 1 The inner side of the lid 2 is provided with a sealing protrusion 22 that matches the edge of the opening of the box body 1, and the sealing protrusion 22 works in conjunction with the box body 1. The partition plate 7 and the partition plate 10 are both provided with cavities, and the cavities are filled with insulation cotton. The edges of the partition plate 7 and the partition plate 10 are provided with sealing strips.

[0028] As a technical optimization of this utility model, the sealing of the lid 2 and the body 1 is enhanced by sealing protrusion 22, the insulation performance of the partition plate 7 and the divider plate 10 is improved by insulation cotton, and the gaps between the components are filled by sealing strips to form a comprehensive sealing and insulation system. This minimizes the heat exchange between the inside and outside of the body 1 and ensures that the items inside the box are always in a suitable temperature environment during long-term transportation, meeting the strict requirements of insulation transportation for fresh food, medicine and other products.

[0029] The working principle and usage process of this utility model are as follows: When using this high-efficiency insulated express box, firstly, according to the size and quantity of the items to be transported, manually move the actuating block 19 in the actuating groove 18 on the front of the partition plate 7, so that the actuating block 19 slides along the actuating groove 18, causing the positioning post 17 to compress the ejector spring 16 in the positioning hole and exit from the positioning groove 15 on the snap-fit ​​groove 6, thus releasing the initial positioning restriction on the partition plate 7; then, push the partition plate 7 to slide up and down along the snap-fit ​​groove 6 on the left and right vacuum insulation plates 5, adjust the partition plate 7 to a suitable height position inside the box body 1, and then release the actuating block 19. Spring 16 returns to its original deformation, pushing positioning pin 17 through positioning hole and re-engaging into positioning groove 15, completing the initial positioning of partition plate 7; then, push partition plate 10, causing it to slide left and right along sliding grooves 8 at the top and bottom of partition plate 7 via slider 9, adjusting partition plate 10 to a position that can divide the interior of box 1 into independent spaces suitable for the size of the items; then, pick up locking bolt 13 in limiting frame 12, pass locking bolt 13 through limiting frame 12 on the inner side of upper and lower vacuum insulation plates 5, and rotate locking bolt 13 clockwise to limit locking bolt 13 against partition plate 10. The locking hole 14 at the bottom of slot 11 is threaded until the locking bolt 13 is tightened, firmly fixing the partition plate 10 in its current position, thus completing the division of the internal space of the box 1. Then, the items to be transported are placed into the respective divided independent spaces, ensuring the items are placed stably to avoid excessive pressure between the items and the inner wall of the box 1, the partition plate 7, or the partition plate 10. Next, the lid 2 is lifted, and the sealing protrusion 22 on the inside of the lid 2 is aligned with the edge of the opening of the box 1. The lid 2 is then slowly closed, ensuring a tight fit between the sealing protrusion 22 and the edge of the opening of the box 1, enhancing the overall sealing of the box 1. Finally, the box is completed. After the lid 2 is closed, the high-efficiency insulated express box with layered mechanical partitions can be handled and transported. During transportation, the cushioning pad 20 protects the items through elastic cushioning. The polyurethane foam 3, vacuum insulation board 5, aluminum foil reflective film, insulation cotton, sealing protrusions 22 and sealing strips work together to achieve high-efficiency insulation, ensuring that the items inside the box are in a suitable temperature environment. The vent 21 ensures air circulation inside the box. After arriving at the destination, open the lid 2, rotate the locking bolt 13 in the opposite direction to disengage it from the locking hole 14, push the partition plate 10 to reset, and then move the toggle block 19 to adjust the position of the partition plate 7, and then take out the items inside the box.
