Technical Field
[0001] This utility model relates to the field of cold chain logistics equipment technology, specifically to a heat-insulating PVC lining for refrigerated boxes. Background Technology
[0002] Refrigerated boxes are increasingly used in cold chain logistics, medical drug transportation, and fresh food storage. The insulation performance and efficient use of internal space of a refrigerated box directly affect the quality and shelf life of the stored items. Currently, refrigerated boxes on the market typically use PVC material as the lining. PVC material has good insulation properties, chemical corrosion resistance, and ease of processing, which can meet refrigeration requirements to a certain extent.
[0003] However, existing PVC insulated liners for refrigerators have significant limitations. Traditional refrigerator liners are often designed as a single unit with fixed internal space, lacking flexible partitioning. When users need to store multiple types of items with different temperature requirements or to prevent cross-contamination of odors, it is difficult to effectively divide the internal space of the refrigerator. Although some refrigerators have fixed partitions, these partitions are in fixed positions and cannot be adjusted according to the actual size and quantity of the items stored, resulting in low space utilization efficiency and failing to fully meet the needs of diverse usage scenarios. To solve the above problems, we propose a new type of PVC insulated liner for refrigerators. Utility Model Content

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-6 A PVC heat-insulating lining for a refrigerator box, comprising a refrigerator box 1, a lid 2 hinged to the top of the refrigerator box 1, and further comprising:
[0029] The thermal insulation layer 3 is installed in the inner cavity of the refrigerator 1. The thermal insulation layer 3 includes an insert-shaped vertical groove 5, a stabilizing horizontal groove 6, and a fixing cavity groove 7.
[0030] The inner lining partition 4 is movably installed in the inner cavity of the insulation layer 3 to divide the inner cavity of the insulation layer 3 into layers. The refrigerator 1 serves as the main body of the entire device, and the lid 2 is hinged to its top, allowing it to be opened and closed for easy access to items by the user. The insulation layer 3 is located in the inner cavity of the refrigerator 1, and its internal structure is the basis for achieving flexible partitioning. The insert-shaped vertical groove 5 is opened at one end of the upper surface of the insulation layer 3 near the box cover 2 and extends to the bottom inner wall, providing an initial channel for the insertion of the inner lining partition plate 4; the stabilizing horizontal groove 6 is symmetrically distributed at both ends of the inner wall of the insulation layer 3 near the box cover 2, and is connected to the insert-shaped vertical groove 5. Its function is to provide a lateral stable support groove for the limiting insert 16 after the partition plate is moved to the appropriate position; the fixing cavity groove 7 is located between the two stabilizing horizontal grooves 6 and is also connected to the insert-shaped vertical groove 5. The limiting teeth 8 on the upper and lower inner walls of the groove 7 can cooperate with the locking teeth 15 on the inner lining partition plate 4 to achieve precise positioning and firm fixation of the partition plate.
[0031] Furthermore, a vertical groove 5 is provided on one end of the upper surface of the insulation layer 3, corresponding to the area near the lid 2. The vertical groove 5 extends to the bottom inner wall of the insulation layer 3. Symmetrically distributed stabilizing horizontal grooves 6 are provided at both ends of the inner wall of the insulation layer 3 near the lid 2. One end of each of the two stabilizing horizontal grooves 6 is connected to the vertical groove 5. This not only provides an initial channel for the insertion of the inner lining partition plate 4, but its extension to the bottom inner wall of the insulation layer 3 ensures that the inner lining partition plate 4 can be vertically inserted into the bottom of the insulation layer, ensuring the integrity and stability of the partition plate insertion process and laying the foundation for subsequent horizontal movement and fixing. The stabilizing horizontal grooves 6 are symmetrically distributed at both ends of the inner wall of the insulation layer 3 near the lid 2 and are connected to the vertical groove 5. In addition to providing a lateral stable support slot for the limiting insert 16, its symmetrical structure can evenly distribute the pressure borne by the inner lining partition plate 4 in the fixed state, enhance the stability of the inner lining partition plate after fixing, and prevent the partition plate from shaking or shifting during use.
[0032] Furthermore, a fixing cavity 7 is provided on the inner wall of the insulation layer 3 near the box cover 2 between two stabilizing horizontal grooves 6. One end of the fixing cavity 7 is connected to the insert-shaped vertical groove 5. The upper and lower inner walls of the fixing cavity 7 are provided with symmetrically distributed limiting teeth 8.
[0033] Furthermore, two symmetrically distributed operating grooves 9 are provided on one side of the inner lining partition plate 4 near the end of the box cover 2. An installation cavity 10 is provided in the inner cavity of the inner lining partition plate 4 near the two operating grooves 9. A partition block 11 is fixedly connected to the center of the inner walls on both sides of the installation cavity 10, and the partition block 11 divides the installation cavity 10 into two equally divided inner cavities.
[0034] Furthermore, two symmetrically distributed sliding blocks 12 are movably engaged at both the upper and lower ends of the inner cavity of the mounting cavity 10, and a return spring 14 is fixedly connected between the two sliding blocks 12 and the upper and lower sides of the partition block 11.
[0035] Furthermore, each of the two operating grooves 9 has a sliding groove connected to the mounting cavity 10 on its inner wall. A pressing block 13 is fixedly connected to one side of the sliding block 12. The pressing block 13 extends through the sliding groove into the inner cavity of the operating groove 9. The sliding groove allows the pressing block 13 to slide up and down.
[0036] Furthermore, a locking tooth 15 is fixedly connected to the lower end of the sliding block 12 near the box cover 2. The locking tooth 15 extends into the fixed cavity 7. A sliding groove 2 is provided on the side of the sliding block 12 near the box cover 2, so that the locking tooth 15 can slide up and down.
[0037] Furthermore, the upper and lower ends of the insulation layer 3 near the box cover 2 are fixedly connected with limit blocks 16. Both limit blocks 16 are movably engaged in the stabilizing transverse groove 6, and the width of the locking teeth 15 is equal to the minimum width of the limit blocks 16.
[0038] Furthermore, the upper and lower surface shapes of the limiting insert 16 match the cross-section of the insert vertical groove 5, and the left and right sides of the limiting insert 16 match the cross-section of the stabilizing horizontal groove 6.
[0039] Working Principle: When using this refrigerated box insulation PVC liner device, its core function is to flexibly divide and fix the internal space to meet diverse usage needs. When it is necessary to divide the inner cavity of the insulation layer 3 into layers, the user takes out the liner divider plate 4 and inserts the two limiting blocks 16 on the divider plate downwards along the insert-shaped vertical grooves 5. The upper and lower surface shapes of the limiting blocks 16 match the cross-section of the insert-shaped vertical grooves 5, and the left and right sides match the cross-section of the stabilizing horizontal grooves 6. This allows the limiting blocks 16 to maintain good guidance and stability during insertion and sliding, avoiding displacement or jamming. When the bottom of the liner divider plate 4 contacts the bottom of the insulation layer 3, the two limiting blocks 16 correspond exactly to the two stabilizing horizontal grooves 6, at which point the position adjustment stage begins.
[0040] The operator simultaneously presses two pressing blocks 13 relative to each other. The pressing blocks 13, connected to the sliding block 12, move the sliding block 12 towards the partition block 11. During this process, the sliding block 12 causes the locking teeth 15 to retract inwards, allowing the locking teeth 15 to slide between the two sets of limiting teeth 8 in the fixed cavity 7, thereby realizing the horizontal movement of the inner lining partition plate 4. The design of the operating groove 9 provides the operator with a comfortable pressing point, facilitating the operation of the pressing blocks 13. The partition block 11 divides the installation cavity 10 into two equal inner cavities, providing space for the movement of the sliding block 12. A return spring 14 is connected between the sliding block 12 and the partition block 11, serving a reset function.
[0041] When the inner lining partition 4 is moved to the required installation position, the operator releases the pressure on the two pressing blocks 13. At this time, the return spring 14 undergoes elastic deformation due to the previous compression, releasing elastic potential energy and pushing the two sliding blocks 12 to reset. The sliding blocks 12 drive the locking teeth 15 to move in opposite directions, so that the two locking teeth 15 engage in the slots in the limiting teeth 8. Since the width of the locking teeth 15 is equal to the minimum width of the limiting insert 16, this size design ensures that the locking teeth 15 can smoothly engage with the limiting teeth 8 and form a firm locking relationship, thereby completing the fixation of the inner lining partition 4 and achieving effective partitioning of the internal space of the refrigerator.
[0042] In subsequent use, if it is necessary to adjust the position of the inner lining partition 4, simply press the pressing block 13 again to separate the locking teeth 15 from the limiting teeth 8, then move the inner lining partition 4 to the new position, and release the pressing block 13 to re-fix it. The whole operation process is convenient and efficient, fully meeting the user's needs for flexible adjustment of the internal space of the refrigerator.
