In the present embodiment, an air-tight door structure for a refrigerator without a dock is disclosed, and referring to fig. 1, the bottom of the opening 110 of the refrigerator 100 is flush with the floor surface 600. Referring to fig. 1, 2, 5 and 6, the air sealing door structure includes a top airbag 200, two side airbags 300, and a bottom airbag module 400, wherein the top airbag 200 is disposed at the top of the doorway 110, the side airbags 300 are disposed at both sides of the doorway 110, the bottom airbag module 400 is movable, and the bottom airbag module 400 can be moved to or from the bottom of the refrigerator compartment 500.

When the refrigerator car is not loaded/unloaded at the port 110, referring to fig. 1 and 5, the top air bag 200 and the two side air bags 300 are in the deflated and contracted state, and the bottom air bag assembly 400 is in the deflated and contracted state and moved to the side of the port 110.

When the refrigerator car is driven to the storage opening 110 for loading/unloading, referring to fig. 2 and 6, the top airbag 200 and the two side airbags 300 are in an inflated state, both sides of the top airbag 200 are in corresponding abutment with the two side airbags 300, the top airbag 200 closes a gap between the top of the refrigerator car 500 and the top of the storage opening 110, and the side airbags 300 close a gap between the side surfaces of the refrigerator car 500 and the side surfaces of the storage opening 110; the bottom air bag assembly 400 is moved to the bottom of the refrigerator car 500 and inflated, the top of the bottom air bag assembly 400 contacts with the bottom of the refrigerator car 500, the bottom of the bottom air bag assembly 400 contacts with the ground 600, and the bottom air bag assembly 400 seals the gap between the bottom of the refrigerator car 500 and the ground 600.

Through the top airbag 200, the side airbag 300 and the bottom airbag module 400, a totally closed carrying action space is formed between the refrigerator carriage 500 and the storage opening 110, the sealing requirement between the refrigerator carriage 500 and the storage opening 110 is met, and the refrigerating effect of goods is improved.

Bottom airbag assembly 400's mobility has improved its convenience of use greatly, and bottom airbag assembly 400 that will be in the state of losing air removes to refrigerator van 500's bottom after the gas refilling, can be according to different refrigerator van 500's height, inflates bottom airbag assembly 400 to suitable height, satisfies not unidimensional refrigerator van 500's sealed demand, and the suitability is stronger. After the loading/unloading work is finished, the bottom airbag module 400 is deflated and then removed.

In some embodiments of the present application, referring to fig. 3 and 4, the bottom airbag assembly 400 includes a mobile cart 410 and a bottom airbag 420 disposed on the mobile cart 410, the bottom airbag 420 being in an inflated state in fig. 3, and the bottom airbag 420 being in a deflated state in fig. 4.

The traveling vehicle 410 moves the bottom airbag 420 into/out of the bottom of the refrigerator compartment 500, and the top of the bottom airbag 420 may contact the bottom of the refrigerator compartment 500 after the bottom airbag 420 is inflated.

After the bottom airbag 420 is inflated, both sides of the bottom airbag 420 are in contact with the side airbags 300 of the corresponding sides, so that a relatively reliable sealing structure is formed in the circumferential direction of the refrigerator compartment 500 by the top airbag 200, the side airbags 300, and the bottom airbag 420.

The bottom airbag module 400 further comprises a blower 430, the blower 430 is fixedly arranged on the moving trolley 410, the blower 430 is communicated with the bottom airbag 420, and the bottom airbag 420 is inflated through the blower 430.
