[0021] As Figures 1-3 shown, the technical solution of the present utility model is a novel double-chamber fresh-keeping box, including a base 1. A threaded rod 2 is provided at the middle of the base 1. Multiple fresh-keeping box bodies 3 are sequentially provided on the threaded rod 2 from top to bottom. A limit sleeve 4 is provided at the top of the threaded rod 2. An internal nut matching with the threaded rod 2 is provided in the limit sleeve 4. Multiple L-shaped top claws 5 are provided on the outer side of the limit sleeve 4.

[0022] The fresh-keeping box body 3 includes a box body 6 and a box cover 7 matching with the box body 6. Multiple buckles are provided on the outer edge of the box cover 7. An annular clamping groove is provided on the outer side of the upper end of the box body 6, and the annular clamping groove is matched with the buckles. Multiple air permeable holes are provided on the box cover 7, and air permeable plugs 8 are provided at the air permeable holes. Multiple placement grooves 9 are provided in the front, rear, left, and right side walls of the box body 6. The upper end of the placement groove 9 penetrates through the upper edge of the box body 6, and a seal is provided at its upper end. Auxiliary packs are placed in the placement groove 9. A first through hole is provided on the bottom wall of the box body 6, and the first through hole is arranged in cooperation with the threaded rod 2. A second through hole matching with the threaded rod 2 is provided on the box cover 7. Sealing plugs 10 are provided at the first through hole and the second through hole. When stacking, the sealing plugs 10 on each box body 6 and box cover 7 are removed and passed through in sequence. A partition 11 is clamped in the box body 6, and the partition 11 divides its interior into two chambers.

[0023] In this embodiment, the vertical end of the L-shaped top claw 5 is fixed to the outside of the limit sleeve 4, and the horizontal end abuts against the upper surface of the fresh-keeping box body 3.

[0024] In this embodiment, one end of the air-permeable plug 8 is fixed to the box cover 7 through a connecting rod.

[0025] In this embodiment, the auxiliary package is a heating package or a cooling package.

[0026] In this embodiment, the box body 6 is a heat-resistant glass box.
