DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 3The utility model provides a technical solution: a pressure-proof fresh-keeping box for vegetable distribution, comprising an inner box body 1, an inner liner 2 is installed inside the inner box body 1, a storage cavity 3 is opened inside the inner liner 2, an outer box body 6 is sleeved on the outer side of the inner box body 1, convex grooves 4 are opened on both sides corresponding to the storage cavity 3, convex blocks 5 are slidably connected inside the convex grooves 4, and the two convex blocks 5 are respectively fixedly connected to the corresponding sides of the outer box body 6, and a screw rod 7 is rotatably connected inside the convex grooves 4, and the screw rod 7 passes through the convex block 5 and is threadedly connected to the convex block 5, so that the convex block 5 drives the outer box body 6 to rise and fall with the rotation of the screw rod 7, and the space between the inner box body 1 and the outer box 6 is adjusted. The space size is suitable for vegetables of different volumes and quantities, and reduces the space occupied when not in use. Placement frames 12 are installed on both sides of the storage cavity 3. Ice bags 13 are placed inside the placement frames 12, which are beneficial to reducing the temperature inside the inner box body 1 and the outer box body 6 to ensure the storage of vegetables. A groove 14 is provided inside the inner box body 1 and at the bottom of the two convex grooves 4. Two worm gears 15 are rotatably connected inside the groove 14. The two worm gears 15 are respectively fixedly connected to the two lead screws 7. A worm 16 is rotatably connected inside the groove 14 and located on one side of the two worm gears 15. The worm 16 is respectively meshed with the two worm gears 15. One side of the inner box body 1 is rotatable. The inner tank 2 is provided with a plurality of positioning grooves 8 at the bottom of the storage cavity 3, wherein the plurality of positioning grooves 8 are connected with partitions 9 to divide the interior of the storage cavity 3 into different spaces, which is convenient for managing vegetables and avoiding squeezing of vegetables. The partitions 9 are provided with a plurality of ventilation holes 20 to avoid the partitions 9 from obstructing the circulation of cold air in the box. The outer box 6 is installed at the top. There is a box cover 10, and a handle 11 is installed on the top of the box cover 10. An exhaust hole 21 is opened inside the box cover 10, which is convenient for cooperating with equipment such as a vacuum pump to extract the air in the inner box body 1 and the outer box body 6, thereby reducing the oxygen content in the box body, which is beneficial to reducing the loss of vegetables.
