Description

[0001] This invention relates to the field of cold chain transportation, and in particular to a modular insulated ice plate structure. Background Technology

[0002] Insulated ice plates, also known as cold storage plates, ice boxes, cold plates, or phase change cold storage plates, are devices that utilize phase change materials to absorb or release heat at specific temperatures, thereby achieving heat preservation and cold preservation functions. They are widely used in cold chain transportation, medical refrigeration, and food preservation.

[0003] Traditional insulated ice plates require the ice plates to be placed in a refrigerator or freezer to freeze completely before being placed in an insulated box with the items to be refrigerated. Once the ice plates melt, they can be refrozen for reuse.

[0004] Currently, long-distance cold chain transportation requires the use of large-capacity ice plates to ensure they don't melt completely before reaching their destination. However, large-capacity ice plates are prone to expansion and deformation during freezing, causing them to fail to fit snugly against the inside of the insulated box. If double-layered, small-capacity ice plates are used, the lack of a connecting structure between them makes it impossible to secure the ice plates, affecting stability during transportation. This requires improvement. Summary of the Invention

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, a modular insulated ice plate structure includes a cold storage plate 1 and a locking mechanism 2.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, the cold storage plate 1 is a long strip with a hollow interior. The surface of the cold storage plate 1 is provided with a groove 11 on the outer side to facilitate lifting and handling of the cold storage plate 1.

[0029] like Figure 4 , Figure 5 As shown, multiple reinforcing columns 12 are formed by inward pressing on both the surface and back side of the cold storage plate 1, and water-permeable holes 13 are provided through the connection positions of the reinforcing columns 12.

[0030] Therefore, by forming reinforcing columns 12 inwardly on both sides of the cold storage plate 1, the internal and external pressure bearing capacity of the cold storage plate 1 is increased, expansion and contraction space is provided, stress concentration is prevented, and the cold storage plate 1 is prevented from bulging or cracking after freezing.

[0031] Meanwhile, by providing water permeable holes 13 on the reinforcing column 12, rainwater or accumulated water can be discharged outward along the water permeable holes 13 during the stacking or use of the cold storage plate 1, thus satisfying the automatic drainage requirement.

[0032] like Figure 2 , Figure 3 , Figure 4 As shown, the cold storage plate 1 consists of two layers, stacked on top of each other. The ends of the two layers of cold storage plates 1 are staggered, and the end plates are half-pieces. The ends of the two layers are flush. The sides of the two layers of cold storage plates 1 are also staggered, and adjacent rows of cold storage plates 1 overlap each other.

[0033] Therefore, by setting up cold storage plates 1 that are staggered and stacked in all directions, the bending resistance of the upper and lower cold storage plates 1 is improved, the deformation of the heat insulation ice plate is reduced, and the connection stability between the two cold storage plates 1 is increased.

[0034] like Figure 2 , Figure 3 , Figure 4 As shown, the locking mechanism 2 is located between two adjacent cold storage plates 1 and connects the upper and lower cold storage plates 1 to achieve the connection and fixation of each row of cold storage plates 1.

[0035] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the locking mechanism 2 includes a locking plate 21, a locking screw tube 22, and a locking screw 23. The locking plate 21 is elongated, and both ends of the cold storage plate 1 are provided with locking grooves 14 with end openings for the locking plate 21 to be inserted, so that after the locking plate 21 is inserted, its surface is flush with the surface of the cold storage plate 1, ensuring the flatness of the surface of the cold storage plate 1 after connection.

[0036] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, locking screw tubes 22 are disposed at both ends of locking plate 21, and locking screws 23 are threadedly connected to locking screw tubes 22. The cold storage plate 1 is provided with end locking holes 15 and intermediate locking holes 16 for the locking screw tubes 22 or locking screws 23 to pass through, wherein the intermediate locking hole 16 is located behind the end locking hole 15, and the end locking holes 15 and intermediate locking holes 16 on the upper and lower cold storage plates 1 are aligned with each other.

[0037] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the locking screw tube 22 near the locking plate 21 and the end cap of the locking screw 23 are both frustum-shaped. The end locking hole 15 and the middle locking hole 16 are both flared, so that the locking screw tube 22 and the locking screw 23 can stably press the cold storage plate 1, thereby achieving a stable connection and fixation of the cold storage plate 1.

[0038] When assembling and using the cold storage plate 1, take out the cold storage plates 1 one by one, so that the upper and lower layers of cold storage plates 1 are back to back and close together with their ends staggered. At the same time, the two sides of the cold storage plates 1 are also staggered in a stepped shape, and the end locking holes 15 on the upper and lower layers of cold storage plates 1 are aligned with the middle locking holes 16.

[0039] Then, the half-piece cold storage plate 1 at the end is removed, and the missing part of the cold storage plate 1 is supplemented. At the same time, the end locking hole 15 is aligned with the middle locking hole 16 to form a large-capacity rectangular heat-insulating ice plate.

[0040] Then, the locking mechanism 2 is taken out, and a portion of the locking screw tube 22 is inserted through the end locking hole 15 on the upper cold storage plate 1 and extends into the middle locking hole 16 on the lower cold storage plate 1. At the same time, the locking plate 21 is embedded in the locking groove 14 on the upper cold storage plate 1.

[0041] Another part of the locking screw tube 22 is inserted into the end locking hole 15 on the lower cold storage plate 1 and extends into the middle locking hole 16 on the upper cold storage plate 1, while the locking plate 21 is embedded in the locking groove 14 on the lower cold storage plate 1.

[0042] Then, each locking screw 23 is inserted through the middle locking hole 16 on the upper and lower cold storage plates 1 respectively, and gradually tightened into the locking screw tube 22 to fix the locking mechanism 2 and complete the connection and fixation between the upper and lower cold storage plates 1.

[0043] Then, rows of assembled cold storage plates 1 are arranged and placed so that the protruding and concave stepped positions on both sides overlap each other to assemble a large-area and large-volume heat-insulating ice plate.

[0044] Therefore, by setting up modular insulated ice plates, batches of small-volume cold storage plates 1 can be frozen independently, reducing the expansion volume of the cold storage plates 1 after freezing. Then, they can be assembled to form large-volume insulated ice plates, so that the insulated ice plates can be stably attached to the inside of the insulated box, which is suitable for long-distance cold chain transportation.

[0045] Meanwhile, during the assembly of the cold storage plate 1, both ends and sides are staggered and overlapped together to achieve stacking and limiting in all directions, thereby improving the bending resistance of the upper and lower cold storage plates 1, reducing the deformation of the insulation ice plate, and increasing the connection stability between the two cold storage plates 1.

[0046] like Figure 4 , Figure 5 , Figure 6 As shown, the end cap of the locking screw 23 is provided with a long strip-shaped first positioning groove 24, and the middle locking hole 16 is provided with a long strip-shaped second positioning groove 17. When the locking screw 23 is tightened, the first positioning groove 24 is aligned with the second positioning groove 17.

[0047] When the locking screw 23 is tightened, the locking screw 23 will drive the first positioning groove 24 to move synchronously. When the locking screw 23 is tightened into the locked state, the first positioning groove 24 on the locking screw 23 approaches the second positioning groove 17 on the cold storage plate 1. Then, a slight driving force is applied to make the first positioning groove 24 and the second positioning groove 17 align with each other, so that the tightness of the locking screw 23 can be visually presented, and the final tightening position of the locking screw 23 is positioned to ensure the stable connection of the upper and lower cold storage plates 1.

[0048] like Figure 4 , Figure 5 , Figure 6 As shown, the bottom surface of the locking screw 23 is provided with a plurality of self-locking blocks 25. The side of the self-locking block 25 facing the tightening direction is arranged in an inclined shape. The bottom walls of the end locking hole 15 and the middle locking hole 16 are provided with self-locking holes 18 for the self-locking blocks 25 to be inserted.

[0049] When the locking screw 23 is rotated, it drives the self-locking block 25 to move synchronously and tighten towards the inclined surface of the self-locking block 25. At the same time, the self-locking block 25 gradually embeds into each self-locking hole 18. As the locking screw 23 is fully tightened, the self-locking block 25 is embedded into the corresponding self-locking hole 18, and under the snapping action of the vertical surface of the self-locking block 25, the reverse rotation of the locking screw 23 is restricted, thereby achieving stable tightening and fixing of the locking screw 23 and ensuring a stable connection between the upper and lower cold storage plates 1.

[0050] like Figure 4 As shown, a protruding ring 3 is provided on one side of the back side of the cold storage plate 1, and the protruding ring 3 surrounds the end locking hole 15 and the middle locking hole 16 on that side. A groove 4 is provided on the other side of the back side of the cold storage plate 1, and the groove 4 surrounds the end locking hole 15 and the middle locking hole 16 on that side, and is used for the protruding ring 3 to be embedded.

[0051] like Figure 4 As shown, the height of the convex ring 3 is greater than the depth of the groove 4. When the convex ring 3 is embedded in the groove 4, there is a gap between the upper and lower cold storage plates 1.

[0052] When the cold storage plates 1 are pressed back to back, the protruding rings 3 on the cold storage plates 1 are embedded in the grooves 4 to achieve the locking and limiting between the upper and lower cold storage plates 1, so as to prevent the cold storage plates 1 from sliding or moving laterally and increase the stability of the cold storage plates 1 after assembly.

[0053] Meanwhile, since the height of the convex ring 3 is greater than the depth of the groove 4, when the convex ring 3 is embedded in the groove 4, there is a 4mm gap between two adjacent cold storage plates 1, which allows for expansion space for the freezing of the cold storage plates 1, so that the upper and lower cold storage plates 1 can be connected and combined smoothly.

[0054] like Figure 3 , Figure 4As shown, one end of the cold storage plate 1 extends outward with a dovetail head 5, and the other end extends outward with a dovetail groove 6 for the dovetail head 5 to be snapped into.

[0055] like Figure 3 , Figure 4 As shown, the bottom surfaces of the dovetail head 5 and the dovetail groove 6 are flush with the back side of the cold storage plate 1, and the top surfaces are lower than the surface of the cold storage plate 1.

[0056] like Figure 3 , Figure 4 , Figure 6 As shown, the lower end face of the locking plate 21 is provided with a trapezoidal pressing block 26 that presses against the dovetail head 5 and the dovetail groove 6.

[0057] By setting mortise and tenon structures at both ends of the cold storage plate 1, a stable connection between adjacent cold storage plates 1 is achieved. At the same time, the addition of the jacket 7 achieves a stable connection between the upper and lower layers of cold storage plates 1. Meanwhile, the thickness of the dovetail head 5 and the dovetail groove 6 is less than the thickness of the cold storage plate 1, so it will not affect the setting of the locking groove 14, allowing the cold storage plates 1 to be arranged and combined flatly.

[0058] like Figure 3 , Figure 7 , Figure 8 As shown, the ends of the upper and lower cold storage plates 1 are wrapped with jackets 7, which include an upper jacket 71, a lower jacket 72 and fastening bolts 73.

[0059] like Figure 7 , Figure 8 As shown, the upper clamping plate 71 and the lower clamping plate 72 are interlocked and clamp the dovetail head 5 and dovetail groove 6 at the end of the cold storage plate 1. The shapes of the upper clamping plate 71 and the lower clamping plate 72 at both ends also match the dovetail head 5 or the dovetail groove 6. Fastening bolts 73 pass through the upper clamping plate 71 and the lower clamping plate 72, thus connecting and fixing the upper clamping plate 71 and the lower clamping plate 72.

[0060] like Figure 7 , Figure 8 As shown, both the upper clamping plate 71 and the lower clamping plate 72 are horizontally provided with connecting plates 74 embedded in the locking groove 14, and the connecting plates 74 are vertically provided with connecting pins 75 that pass through the end locking hole 15 or the middle locking hole 16.

[0061] like Figure 7 , Figure 8 As shown, the upper and lower connecting pins 75 are interlocked and fit into the inner side of the end locking hole 15 or the middle locking hole 16. The ends of the connecting pins 75 are respectively provided with interlocking hooks 76 and locking grooves 77, so as to realize automatic locking after the connecting pins 75 are interlocked.

[0062] After the upper and lower layers of cold storage plates 1 are assembled together, observe whether the two ends of the cold storage plate 1 are dovetail heads 5 or dovetail grooves 6, and then select the appropriate jacket 7, that is, select the jacket 7 with a raised or recessed interior, so as to fit the ends of the cold storage plate 1.

[0063] Then, the upper clamping plate 71 and the lower clamping plate 72 are fastened together, so that the connecting pins 75 on the upper clamping plate 71 and the lower clamping plate 72 are gradually inserted into the end locking hole 15 or the middle locking hole 16. Then, the upper clamping plate 71 and the lower clamping plate 72 are pressed closer to each other, so that the connecting plate 74 is embedded in the locking groove 14. At the same time, the locking hook 76 and the locking groove 77 at the end of the connecting pin 75 are hooked together, so as to achieve the snap-fit ​​fixation between the connecting pins 75 with opposite positions.

[0064] Finally, tighten the fastening bolt 73 to clamp the dovetail head 5 or dovetail groove 6 at the end of the cold storage plate 1, and fix the end position of the cold storage plate 1 together, thus completing the stable connection and fixing of the cold storage plate 1 and preventing the end position of the cold storage plate 1 from tilting up, ensuring the flatness of the cold storage plate 1 after assembly.

[0065] Meanwhile, when the assembled cold storage plate 1 is installed and used, the jacket 7 can form a slider, so it can be directly slid into the slide rail inside the cold chain vehicle, thereby realizing the convenient installation of the cold storage plate 1 and improving the convenience of using the cold storage plate 1.

[0066] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
