[0006] Preferably, the inflation mechanism includes an air pump, which is fixedly mounted on the top of the door frame body, and the air inlet end of the air pump is connected to an air inlet pipe, one end of the air inlet pipe passes through the door frame body and extends to the interior of the first sealing groove, one end of the air inlet pipe extending to the interior of the first sealing groove is connected to the top of the outer surface of the airbag, and the air outlet end of the air pump is connected to an air outlet pipe.
[0007] Preferably, an electromagnetic control valve is provided on the outer surface of the air intake pipe.
[0008] Preferably, a first sealing strip is fixedly installed on the rear portion of the sealing door, and a second sealing strip matched with the first sealing strip is fixedly installed on the front portion of the inner cavity of the installation slot.
[0009] Preferably, a handle is fixedly connected to the front portion of the sealed door.
[0010] Preferably, a control button is fixedly mounted on the rear portion of the handle.
[0011] Beneficial Effects
[0012] The utility model provides an airtight cold storage door. Compared with the existing technology, it has the following beneficial effects:
[0013] The utility model controls the air outlet pipe on the air pump to ventilate the air bag, and the air in the air bag is filled with gas in the first sealing groove and the second sealing groove, which can well block the gap on the surface of the sealing door, effectively prevent the cold air in the cold storage from overflowing and losing, and improve the sealing effect of the cold storage door, thus ensuring the normal use of the cold storage.

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] See also Figure 1-6The utility model provides a technical solution: an airtight cold storage door, including a door frame body 1, a mounting groove 2 is opened at the front of the door frame body 1, a sealing door 3 is hinged on one side of the mounting groove 2 through a hinge, a first sealing groove 4 is opened inside the mounting groove 2, an air bag 5 is fixedly installed inside the first sealing groove 4, a second sealing groove 6 adapted to the air bag 5 is opened on the outer surface of the sealing door 3, and an inflation mechanism 7 is arranged on the top of the door frame body 1.
[0023] Furthermore, in order to facilitate the inflation of the airbag 5, the inflation mechanism 7 includes an air pump 71, which is electrically connected to the battery and controlled by the control button 11. The air pump 71 is fixedly installed on the top of the door frame body 1, and the air inlet end of the air pump 71 is connected to an air inlet pipe 72. One end of the air inlet pipe 72 passes through the door frame body 1 and extends to the interior of the first sealing groove 4. The end of the air inlet pipe 72 extending to the interior of the first sealing groove 4 is connected to the upper part of the outer surface of the airbag 5. The air outlet end of the air pump 71 is connected to an air outlet pipe 73. The outer surface of the air inlet pipe 72 is provided with an electromagnetic control valve 12. The electromagnetic control valve 12 is electrically connected to the battery and controlled by the control button 11.
