Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cold chain transportation technology, and in particular relates to a quick-assembly frame for vacuum insulation layer of e-commerce cold chain boxes. Background Technology
[0002] In the e-commerce cold chain logistics sector, cold chain transport boxes, as core equipment for maintaining a low-temperature environment, directly impact the quality and safety of temperature-sensitive goods such as fresh food and pharmaceuticals. Cold chain transport boxes typically employ a multi-layered composite structure, including an outer shell, an internal frame, and a vacuum insulation layer. The vacuum insulation layer, due to its extremely low thermal conductivity, is widely used in cold chain boxes; however, because of its fragile material, it requires a rigid frame for support and reinforcement to prevent damage or failure caused by compression or vibration during transportation.
[0003] Existing cold chain box frames are mostly made of metal or high-strength plastic and are fixed to the outer shell by bolts. Since the vacuum insulation layer needs to be cleaned regularly to remove condensation and stains and prevent the growth of microorganisms, and the bolt connection requires professional tools to disassemble, the operation is cumbersome, especially in outdoor or warehouse environments, which increases maintenance costs. To address these issues, we provide a quick-install frame for the vacuum insulation layer of e-commerce cold chain boxes. Utility Model Content
[0004] The purpose of this utility model is to provide a quick-assembly frame for the vacuum insulation layer of e-commerce cold chain boxes. By combining the positioning and limiting mechanism and the blocking mechanism, it solves the problem of reduced disassembly and assembly efficiency caused by the bolt connection method used in the existing technology.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0006] This utility model relates to a quick-assembly frame for a vacuum insulation layer of an e-commerce cold chain box, comprising a cold chain box body, an internal support frame, a vacuum insulation shell fixedly connected inside the support frame, and a vacuum insulation plate movably connected to the front side of the vacuum insulation shell via a first hinge; a positioning and limiting mechanism is provided at the bottom of the cold chain box body, the positioning and limiting mechanism including a horizontal plate fixedly connected to the bottom of the cold chain box body, a positioning groove opened at the top of the horizontal plate, a positioning block slidably connected inside the positioning groove, and a limiting plate disposed at the top of the positioning block; a blocking mechanism is provided at the front side of the cold chain box body, the blocking mechanism including a baffle disposed at the front side of the cold chain box body, and a pressing block disposed at the top of the baffle.
[0007] The present invention is further configured such that the positioning and limiting mechanism includes a connecting plate fixedly connected to the top of the positioning block, a housing fixedly connected to the top of the horizontal plate, a movable plate fixedly connected to one side of the limiting plate, a movable rod movably connected to one side of the movable plate, and a spring fixedly connected to one side inside the housing.
[0008] The present invention is further configured such that a limit rod is fixedly connected to one side of the movable rod, and a positioning plate is fixedly connected to one side of the housing.
[0009] The present invention is further configured such that sliders are fixedly connected to the top and bottom of the movable plate, and the sliders are slidably connected to one side of the inside of the housing.
[0010] The present invention is further configured such that the spring is fixedly connected to the movable plate, and the spring is sleeved on the surface of the movable rod.
[0011] The present invention is further configured such that a magnetic sealing door is movably connected to the front side of the cold chain box body via a second hinge, and a handle is fixedly connected to one side of the magnetic sealing door.
[0012] The present invention is further configured such that a rubber sealing ring is fixedly connected inside the vacuum insulation shell, and a sealing pressure plate is fixedly connected to the rear side of the vacuum insulation plate.

[0015] 2. This utility model, through the assembly structure between the support frame and the cold chain box, allows for flexible adjustment of the vacuum insulation shell size for different cargo sizes. The positioning block and the limiting plate, along with the mechanical limiting of the movable rod, prevent the insulation layer from shifting due to bumps during transportation, thus ensuring the safety of cold chain transportation.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example 1
[0026] Please see Figures 1-5 This utility model is a quick-assembly frame for a vacuum insulation layer of an e-commerce cold chain box, including a cold chain box body 1. The cold chain box body 1 is a device used to ensure that items maintain a low-temperature environment during transportation or storage. It is a mature existing technology and will not be described in detail here. A support frame 2 is set inside the cold chain box body 1. A vacuum insulation shell 3 is fixedly connected inside the support frame 2. A vacuum insulation plate 4 is movably connected to the front side of the vacuum insulation shell 3 through a first hinge. The vacuum insulation shell 3 and the vacuum insulation plate 4 can form a sealed environment for storing items. A positioning and limiting mechanism is set at the bottom of the cold chain box body 1. The positioning and limiting mechanism includes a horizontal plate 5 fixedly connected to the bottom of the cold chain box body 1, a positioning groove 6 opened at the top of the horizontal plate 5, a positioning block 7 slidably connected inside the positioning groove 6, the size of the positioning groove 6 is adapted to the positioning block 7, and a limiting plate 8 is set at the top of the positioning block 7. A blocking mechanism is set at the front side of the cold chain box body 1. The blocking mechanism includes a baffle 9 set at the front side of the cold chain box body 1 and a pressing block 10 set at the top of the baffle 9.
[0027] Example 2
[0028] Please see Figures 1-5 Based on Embodiment 1, the positioning and limiting mechanism further includes a connecting plate 11 fixedly connected to the top of the positioning block 7. The top of the connecting plate 11 is fixedly connected to the support frame 2. The front side of the connecting plate 11 contacts the limiting plate 8. A housing 12 is fixedly connected to the top of the horizontal plate 5. A movable plate 13 is fixedly connected to one side of the limiting plate 8. The movable plate 13 is located inside the housing 12. A movable rod 14 is movably connected to one side of the movable plate 13. A spring 15 is fixedly connected to one side inside the housing 12. The movable rod 14 is movably connected to the movable plate 13 through a bearing. The side of the movable rod 14 away from the movable plate 13 extends through to the side of the housing 12 away from the movable plate 13. A limiting pull rod 16 is fixedly connected to one side of the movable rod 14. A positioning plate is fixedly connected to one side of the housing 12. Slider blocks are fixedly connected to the top and bottom of the movable plate 13. The sliders are slidably connected to one side inside the housing 12. The top and bottom of the housing 12 are provided with openings adapted to the sliders. The slide groove, spring 15 and movable plate 13 are fixedly connected. Spring 15 is sleeved on the surface of movable rod 14. The front side of cold chain box body 1 is movably connected to magnetic sealing door 17 through second hinge. Magnetic sealing door 17 is fixedly connected to baffle 9 and pressing block 10. Magnetic sealing door 17 and cold chain box body 1 are magnetically fixed and sealed. When magnetic sealing door 17 is magnetically sealed, baffle 9 is located on one side of limit pull rod 16 to limit and reinforce it, prevent limit plate 8 from falling off, and ensure the limiting effect of limit plate 8 on connecting plate 11. The pressing block 10 abuts against vacuum insulation plate 4 to seal vacuum insulation shell 3. A handle is fixedly connected to one side of magnetic sealing door 17. A handle is also fixedly connected to the top of cold chain box body 1 to facilitate the transfer of cold chain box body 1 by users. Rubber sealing ring 18 is fixedly connected inside vacuum insulation shell 3. Sealing pressure plate 19 is fixedly connected to the rear side of vacuum insulation plate 4.
[0029] The working principle of this utility model is as follows: Open the vacuum insulation plate 4, place the items that need to be transported by cold chain into the vacuum insulation shell 3, so that the vacuum insulation plate 4 seals the vacuum insulation shell 3. At this time, the sealing pressure plate 19 squeezes the rubber sealing ring 18 to enhance the sealing performance. When the magnetic sealing door 17 is closed, the baffle 9 rotates with the door to the position of the limit pull rod 16, and the pressure block 10 presses the vacuum insulation plate 4 simultaneously, completing the mechanical limit and magnetic fixation.
[0030] When the support frame 2 needs to be disassembled for cleaning the inside of the vacuum insulation shell 3, pull the limiting rod 16 to release the limiting plate 8 from the connecting plate 11. Then, rotate the limiting rod 16 to allow the positioning plate to limit the pulled rod 16. Pulling the support frame 2 forward allows the positioning block 7 to disengage from the positioning groove 6, enabling quick disassembly and cleaning. Reversing this process completes the quick assembly of the support frame 2. Through the synergistic effect of mechanical linkage and magnetic adsorption, this design balances the need for rapid disassembly and assembly with long-term sealing reliability, making it suitable for e-commerce cold chain logistics scenarios with high requirements for temperature control efficiency and ease of maintenance.
[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
