DETAILED DESCRIPTION

[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-7 In the first embodiment, a controlled atmosphere fresh-keeping box includes

[0033] The foam box 10 has an upper end covered with a foam cover 20;

[0034] A plurality of lower positioning plates 11, all of which are L-shaped, arranged in a ring shape and fixedly connected to the bottom of the foam box 10;

[0035] A plurality of upper positioning plates 21, all of which are L-shaped, are fixedly connected to the foam cover 20 at positions corresponding to the lower positioning plates 11;

[0036] A positioning sleeve 30 is located inside the foam box 10;

[0037] A partition 40 is fixedly connected to the inner wall of the positioning sleeve 30, and the partition 40 separates the positioning sleeve 30 into a plurality of storage spaces 41;

[0038] The bottom sealing film 50 is disposed at the lower end of the positioning sleeve 30 and is used to seal the lower end of the positioning sleeve 30 and block the lower end of the storage space 41;

[0039] A blocking net 42 is detachably disposed on the inner wall of the positioning sleeve 30 and is used to block the upper port of the storage space 41;

[0040] The sealing film sleeve 60, the lower port sealing sleeve is arranged on the outer wall of the upper port of the positioning sleeve 30, the sealing film sleeve 60 has two vent pipes 62, and the sealing port 61 of the sealing film sleeve 60 is heat-sealed;

[0041] Among them, the L-shaped inner walls of the lower positioning plates 11 clamp the lower end wall and the lower end of the side wall of the positioning sleeve 30, and the L-shaped inner walls of the upper positioning plates 21 clamp the upper end wall and the upper end of the side wall of the positioning sleeve 30.

[0042] This embodiment is implemented as follows:

[0043] When the present application is in use, the lower port of the positioning sleeve 30 is first sealed with the bottom sealing film 50, and the lower port of the sealing film sleeve 60 is sleeved on the outer wall of the upper port of the positioning sleeve 30 and sealed, and then the lily scales are placed in the storage space 41 through the sealing port 61, and then the baffle 42 is fixed to the inner wall of the positioning sleeve 30 so that the baffle 42 can seal the upper port of the storage space 41, and then after a part of the air is extracted through the ventilation pipe 62, a part of the fresh-keeping gas is introduced, and then the sealing port 61 is sealed, and finally the foam cover 20 is covered to achieve the clamping of the upper positioning plate 21 and the lower positioning plate 11 on the side wall of the positioning sleeve 30, and the intersection of the foam box 10 and the foam cover 20 is glued with tape; and the gap between the positioning sleeve 30 and the foam box 10 can be filled with ice bags.

[0044] Compared with the prior art, the present invention has the advantages of being more environmentally friendly and improving the transportation and preservation time.

[0045] The positioning sleeve 30 is made of foam material, which has low cost and good heat preservation and buffering effect.

[0046] See also Figure 2 , 6 , the two ends of the blocking net 42 are respectively nailed to the inner wall of the positioning sleeve 30 through the positioning pins 43;

[0047] The positioning pin 43 can penetrate the blocking net 42 and be nailed on the positioning sleeve 30, so as to facilitate the positioning of the blocking net 42.
