Description

Technical Field

[0001] This utility model relates to the field of cold chain transportation technology, and in particular to a modular cold chain transportation insulated box. Background Technology

[0002] In daily life, the transportation of various foods such as vegetables, fruits and meats relies on cold chain systems. Cold chain transportation requires special refrigerated or frozen vehicles. In addition to having the basic structure and performance of trucks, these vehicles must also be equipped with refrigeration or freezing insulation facilities. Insulation facilities include cold chain insulated boxes, ice packs and dry ice refrigerated boxes. Insulated boxes are widely used because of their good temperature control.

[0003] A search revealed Chinese Patent Publication No. CN214824966U, which discloses a detachable insulated cold chain transport box. The box includes a body and a lid that covers the body. The body includes side panels and a bottom plate connected to the bottom of the side panels. Multiple side panels are provided, forming a cavity between the bottom plate and the lid. Adjacent side panels are detachably connected by connectors, and the side panels and bottom plate are detachably connected by connecting components. This application facilitates transportation. However, in actual use, the aforementioned device has drawbacks. The alignment and connection between the panels are achieved through hinges. Prolonged vibrations in the vehicle can cause the hinges to loosen, affecting the box's stability and reducing its insulation effect. Therefore, a modular insulated cold chain transport box is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a modular insulated cold chain transport box, which aims to improve the problem that the connection between the box panels by hinges in the existing technology can lead to loosening between the hinges and the box panels after long-term use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular cold chain transport insulated box, comprising a base plate and a combination plate. The top of the base plate has insertion slots around its perimeter. Multiple combination plates have connecting slots on their front and rear sides. Multiple combination plates are fixedly connected to their left and right sides. Multiple combination plates have rotating slots on their tops. A screw is rotatably connected to the inner side of each rotating slot. A perforated groove is formed at the top of the screw. A pressing block is threaded to the bottom of the screw. Sliding columns are slidably connected to the left and right sides inside each insertion slot. An angled block is fixedly connected to the adjacent end of two sliding columns. A spring is fixedly connected to the outer wall of each sliding column. Engaging slots are formed on the opposite sides of the multiple combination plates. An adjustment mechanism is provided on the top of the base plate.

[0006] The above technical solution involves arbitrarily installing two corresponding combination plates on both sides of the base plate, connecting the bottom of the combination plates to the insertion slots. At this time, the beveled blocks inside the insertion slots will be engaged in the engagement slots on the combination plates under the pressure and the rebound of the second spring. Finally, the other two combination plates are connected to the connecting plate through the connecting slots to achieve the assembly of the entire combination plate. Finally, the beveled blocks are engaged by the pressure method. This modular assembly not only improves the installation efficiency but also saves storage space.

[0007] As a further description of the above technical solution:

[0008] The adjustment mechanism includes a partition plate that is slidably connected between multiple combination plates. Each of the multiple combination plates has a limit groove on an adjacent side. Each of the multiple limit grooves has a limit block slidably connected to an adjacent side. The multiple limit blocks are fixedly connected to the left and right sides of the partition plate. Each of the top left and right sides of the partition plate has a sliding groove. A locking post is slidably connected inside the sliding groove. A spring is fixedly connected to the outer wall of the locking post. A buckle plate is fixedly connected to the top of the outer wall of the locking post. Each of the multiple combination plates has multiple locking holes on an adjacent side.

[0009] Through the above technical solution, the partition plate can divide the internal space of the insulated box, allowing for the retrieval of materials with different needs by category, thus preventing rapid loss of internal temperature. At the same time, by squeezing the buckle plate inward, the locking post can be disengaged from the locking holes on both sides, allowing for free adjustment of height according to actual needs, making it more flexible to use.

[0010] As a further description of the above technical solution:

[0011] The adjustment mechanism also includes a sealing strip, which is fixedly connected to the outer wall of the partition plate.

[0012] Through the above technical solutions, the sealing strip can improve the functionality of the partition plate and greatly prevent heat loss.

[0013] As a further description of the above technical solution:

[0014] An outer sealing ring is fixedly connected to the top of the base plate, an inner sealing ring is fixedly connected to the top of the base plate, and a waterproof plate is fixedly connected to the inner side of the inner sealing ring.

[0015] Through the above technical solution, the outer sealing ring and the inner sealing ring can effectively seal the space between the combined plate and the base plate, preventing heat loss.

[0016] As a further description of the above technical solution:

[0017] A hinge is rotatably connected to the rear side of the rear panel, and a box cover is rotatably connected to the outer wall of the hinge.

[0018] The above technical solution connects the combined panel and the box cover via hinges, and the box cover ensures the airtightness of the combined panel's interior.

[0019] As a further description of the above technical solution:

[0020] The top left and right sides of the lid have storage slots, and the inside of the storage slots is rotatably connected to a handle.

[0021] The above technical solution allows the handle to rotate from the storage slot during use, which not only facilitates the stacking of multiple insulated boxes but also does not affect their use.

[0022] As a further description of the above technical solution:

[0023] The top left and right sides of the box cover are fixedly connected with magnetic blocks, and the rear side of the combined plate is provided with magnetic grooves.

[0024] With the above technical solution: when the box lid and the assembly panel are disassembled and transported, the box lid is flipped backward. At this time, the magnetic block can make the box lid stick to the assembly panel, thus preventing shaking.

[0025] As a further description of the above technical solution:

[0026] The front side of the box cover is fixedly connected with buckles, and the front side of the combined plate is fixedly connected with fasteners.

[0027] The above technical solution involves flipping the fastener so that it engages with the buckle, thus locking the combined panel and the lid together.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, any two corresponding combination plates are inserted into the insertion slot, and four combination plates are quickly spliced ​​together through the connecting plate and the connecting slot. When the combination plate is inserted into the insertion slot, the beveled block inside the insertion slot will be squeezed and spring rebounded into the locking groove on the combination plate. When disassembly is required, simply rotate the screw to insert the extrusion block between the two beveled blocks, so that the beveled blocks are squeezed and disengaged from the locking groove, thus completing the quick disassembly. This modular assembly not only improves installation efficiency but also saves storage space.

[0030] 2. In this utility model, the partition plate is installed by limiting the groove. The locking holes are distributed at multiple heights on the inner side of the combined plate. Under the rebound action of the spring, the locking post is locked into the locking hole on the inner side of the combined plate, thus completing the fixed locking of the partition plate. When adjusting, by pressing the buckle plate inward, the locking post can be disengaged from the locking holes on both sides, and the height can be freely switched according to actual needs, making it more flexible to use.

The top of the screw 9 has a perforated groove 7, and the bottom of the screw 9 is threadedly connected to an extrusion block 10. The bottom of the screw 9 passes through the top of the composite panel 4 and connects to the extrusion block 10. Rotating the screw 9 drives the extrusion block 10 to slide downwards. Sliding pillars 11 are slidably connected to the left and right sides of the insertion groove 3. The adjacent ends of two sliding pillars 11 are fixedly connected to... The outer wall of the beveled block 13 and the sliding column 11 is fixedly connected with a spring 12. Multiple combination plates 4 have locking grooves 14 on opposite sides. When a combination plate 4 is inserted into the insertion slot 3, the locking groove 14 at the bottom of the combination plate 4 is locked by the beveled block 13, completing the quick installation. Simultaneously, when disassembly is required, simply rotate the screw 9 to insert the pressing block 10 between two beveled blocks 13, causing the beveled blocks 13 to be compressed and disengaged from the locking groove 14, completing the quick disassembly. This completes the modular design of the insulation box. This design effectively solves the space utilization problem and improves the service life of the insulated box. An adjustment mechanism 2 is provided on the top of the bottom plate 1. An outer sealing ring 15 is fixedly connected to the top of the bottom plate 1, and an inner sealing ring 16 is fixedly connected to the top of the bottom plate 1. A waterproof plate 17 is fixedly connected to the inner side of the inner sealing ring 16. A hinge 18 is rotatably connected to the rear side of the rear combined plate 4. A box cover 19 is rotatably connected to the outer wall of the hinge 18. The outer sealing ring 15 and the inner sealing ring 16 can ensure the sealing between the bottom plate 1 and the combined plate 4 to prevent temperature leakage.

[0040] Specifically, the upper surface edge of the base plate 1 is designed with insertion grooves 3. These insertion grooves 3 can precisely accommodate four composite panels 4, allowing the composite panels 4 to be fully inserted into the base plate 1. To enhance the stability of the structure and the ease of assembly, the composite panels 4 on both the left and right sides are provided with connecting grooves 5 on the front and back sides, while the composite panels 4 on the front and back sides are fixed with connecting plates 6 on the left and right sides. The two sides of the composite panels 4 are respectively provided with connecting plates 6 and connecting grooves 5. Through the cooperation of connecting plates 6 and connecting grooves 5, multiple composite panels 4 can be quickly assembled. This design not only makes the assembly process faster, but also makes it more robust and reliable during use. In addition, each composite panel 4 has a rotating groove 8 on its top.

The bottom of the screw 9 passes through... The top of the combination plate 4 is connected to the extrusion block 10. By rotating the screw 9, the extrusion block 10 can be driven to slide downward. In order to further enhance the modular design of the insulation box, the opposite sides of the multiple combination plates 4 are provided with locking grooves 14. When the combination plate 4 is inserted into the insertion groove 3, the locking groove 14 at the bottom of the combination plate 4 will be locked by the beveled block 13, thereby completing the quick fixed installation. When disassembly is required, simply rotate the screw 9 to insert the extrusion block 10 between the two beveled blocks 13. After being squeezed, the beveled block 13 will disengage from the locking groove 14. This overall modular insulation box design can not only effectively solve the space utilization problem, but also significantly improve the service life of the insulation box. The outer sealing ring 15 and the inner sealing ring 16 can ensure the sealing between the bottom plate 1 and the combination plate 4, effectively avoiding temperature leakage, thereby maintaining a constant temperature environment inside the insulation box.

[0041] Reference Figure 2 , Figure 4 and Figure 5The adjusting mechanism 2 includes a partition plate 203, which is slidably connected between multiple combined plates 4. The partition plate 203 enables the interior of the insulation box to form two spaces, which can prevent a large amount of temperature loss and also realize the classification of materials. Each side of the multiple combined plates 4 has a limiting groove 201, and each side of the multiple limiting grooves 201 is slidably connected to a limiting block 202. The partition plate 203 and the limiting block 202 are integrally formed and are limited by the limiting grooves 201 on the inner side of the combined plates 4 to ensure stability. The multiple limiting blocks 202 are fixedly connected to the left and right sides of the partition plate 203. The top left and right sides of the partition plate 203 have sliding grooves. The sliding groove 205 has a sliding pin 206 slidably connected inside. The outer wall of the pin 206 is fixedly connected to a spring 208. Multiple locking holes 209 are opened on the adjacent side of the multiple combination plates 4. The pin 206 is installed on both sides of the partition plate 203 through the sliding groove 205. Under the rebound action of the spring 208, the pin 206 is locked in the locking hole 209 on the inner side of the combination plate 4. The locking holes 209 are distributed at multiple heights on the inner side of the combination plate 4, which facilitates adjustment and improves storage and adjustment. The top of the outer wall of the pin 206 is fixedly connected to a buckle plate 207. The adjustment mechanism 2 also includes a sealing strip 204, which is fixedly connected to the outer wall of the partition plate 203.

[0042] Specifically, the use of partition 203 creates two independent spaces inside the insulated box. This spatial division not only helps prevent significant temperature loss but also effectively enables the categorized management of the contents. On the two combined plates 4 on the front and rear sides, adjacent sides are specially designed with limiting grooves 201, and adjacent sides of the limiting grooves 201 are fitted with sliding limiting blocks 202. These limiting blocks 202 are integrally formed with the partition 203 and are positioned using the limiting grooves 201 on the inner side of the combined plate 4, thus ensuring the stability of the entire structure. Sliding mechanisms are also provided on the top left and right sides of the partition 203. The sliding groove 205 is connected to a locking post 206 inside. A spring 208 is fixed on the outer wall of the locking post 206, so that the locking post 206 can be firmly locked into the locking hole 209 on the inner side of the combination plate 4 under the rebound action of the spring 208. The locking hole 209 is distributed at multiple different height positions on the inner side of the combination plate 4. This design makes it easy for users to adjust the height as needed, thereby improving the flexibility of storage and the convenience of adjustment. The sealing strip 204 is fixedly connected to the outer wall of the partition plate 203 to ensure the sealing performance of the inside of the insulated box, thereby better maintaining the temperature inside the box and preventing heat loss.

[0043] Reference Figure 1 and Figure 2The top left and right sides of the lid 19 are provided with storage slots 20, and the inside of the storage slots 20 is rotatably connected to handles 21.

The front side of the lid 19 is fixedly connected to buckles 25, and the front side of the front combination plate 4 is fixedly connected to fasteners 24.

[0044] Specifically, storage slots 20 are provided on the top of the lid 19. The handles 21 are rotatably connected inside the storage slots 20, making it easier for users to open or close the lid 19. In addition, magnetic slots 23 are provided on the rear side of the rear combination plate 4. The magnetic slots 23 can perfectly cooperate with the magnetic blocks 22 to ensure that the lid 19 can be firmly attached to the rear combination plate 4 when closed. Buckles 25 are fixed on the front side of the lid 19. The buckles 25 can be tightly cooperated with the fasteners 24 to achieve a fast and stable locking mechanism.

[0045] Working principle: First, any two corresponding combination plates 4 are installed on both sides of the base plate 1, so that the bottom of the combination plate 4 is connected to the insertion slot 3. The two sides of the combination plate 4 are respectively provided with connecting plates 6 and connecting slots 5. The connection between the connecting plates 6 and the connecting slots 5 enables the rapid splicing of multiple combination plates 4, which not only makes the assembly faster, but also, when the combination plate 4 is inserted into the insertion slot 3, the beveled block 13 inside the insertion slot 3 will be squeezed and spring 12 will rebound and engage in the engaging slot 14 on the combination plate 4. When disassembly is required, simply rotate the screw 9 to insert the pressing block 10 between the two beveled blocks 13, so that the beveled blocks 13 are squeezed and disengaged from the engaging slot 14, thus completing the rapid disassembly.

[0046] Furthermore, the partition plate 203 can divide the interior space of the insulated box to prevent excessive heat loss. The partition plate 203 is limited and installed by the limiting groove 201 on the inner side of the combination plate 4. At the same time, the locking holes 209 are distributed at multiple heights on the inner side of the combination plate 4. Under the rebound action of the spring 208, the locking post 206 is locked into the locking hole 209 on the inner side of the combination plate 4, thus completing the fixed locking of the partition plate 203. When adjusting, by pressing the buckle plate 207 inward, the locking post 206 can be disengaged from the locking holes 209 on both sides, and the height can be freely switched according to actual needs, making it more flexible to use.
