[0002] With the update of freezing and refrigeration technology, the tentacles of cold storage projects have penetrated into more fields, and have developed in the fields of chemical raw materials, pharmaceuticals, scientific research, cold drinks, flowers, green plants, tea, medicines, electronic instruments, mushroom cultivation, atmosphere control storage, logistics, etc. The cold storage door refers to the insulated and closed door installed in cold storage equipment, frozen warehouses and other freezing environment equipment.

[0003] During the use of the cold storage, the cold storage door needs to be opened and closed frequently. Conventional cold storage doors are sealed by installing sealing strips on the side walls. However, these sealing strips will gradually be worn and damaged after long-term opening and closing friction of the cold storage door, resulting in gaps and affecting the insulation effect of the cold storage door.

[0004] Therefore, a cold storage door for cold storage insulation is proposed. Summary of the invention

[0005] The utility model aims to provide a cold storage door for cold storage insulation, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cold storage door used for cold storage insulation, comprising a wall, a door body is installed on the wall, an inner baffle is installed on one side of the wall, an outer baffle is installed on one side of the door body, a sealing airbag is installed on the inner wall of the outer baffle, and the sealing airbag is attached to the outer side of the inner baffle.

[0007] Preferably, a plurality of air pumps are installed on the other side of the door body, and a plurality of air pipes are installed on the air pumps.

[0008] Preferably, a plurality of the air pipes pass through the door body and are connected to the sealing airbag.

[0009] Preferably, a plurality of air pressure sensors are evenly installed inside the sealed airbag.

[0010] Preferably, a controller for controlling the operation of the air pump and detecting the air pressure is installed in the middle of the door body.

[0011] Preferably, the inner baffle and the outer baffle are both made of heat-insulating materials.

[0012] Preferably, the sealing airbag is made of low-temperature resistant rubber.

[0013] Compared with the prior art, the utility model has the following beneficial effects: when the cold storage door is closed, the sealing airbag can be inflated to seal the gap, thereby avoiding the leakage of cold air; when the cold storage door needs to be opened, the sealing airbag will be contracted, thereby effectively avoiding friction damage when opening the cold storage door.

[0020] 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. Example

[0021] See also Figure 1-5 The utility model provides a technical solution: a cold storage door for cold storage insulation, comprising a wall 1, a door body 2 is installed on the wall 1, an inner baffle 6 is installed on one side of the wall 1, an outer baffle 7 is installed on one side of the door body 2, and a sealing airbag 8 is installed on the inner wall of the outer baffle 7, and the sealing airbag 8 is attached to the outer side of the inner baffle 6.

[0022] like Figure 1 and Figure 5 As shown: multiple air pumps 4 are installed on the other side of the door body 2, and multiple air pipes 5 are installed on the air pump 4. The multiple air pipes 5 pass through the door body 2 and are connected with the sealing airbag 8. Through the above arrangement, it is more convenient and quick to inflate the inside of the sealing airbag 8, so that the sealing airbag 8 swells to fill the gap between the inner baffle 6 and the outer baffle 7, thereby playing a sealing role.

[0023] like Figure 5As shown: a plurality of air pressure sensors are evenly installed inside the sealing airbag 8; through the above arrangement, the air pressure inside the sealing airbag 8 can be checked at multiple locations, thus avoiding the situation in which sealing failure due to air leakage affects the normal use of the cold storage door.

[0024] like Figure 1 As shown: a controller 3 for controlling the operation of the air pump 4 and detecting the air pressure is installed in the middle of the door body 2; through the above settings, the controller 3 can quickly control the operation of the air pump 4 to complete the inflation and deflation work, and at the same time monitor the air pressure through the controller 3. When the air pressure drops, an alarm will be sounded to remind the staff that there is an air leak.

[0025] like Figure 2 and Figure 3 As shown: the materials of the inner baffle 6 and the outer baffle 7 are both thermal insulation materials.

[0026] like Figure 3 As shown: the material of the sealing airbag 8 is low-temperature resistant rubber; through the above settings, the sealing airbag 8 can be more adapted to the working environment of the cold storage.

[0027] Working principle: When the cold storage door body 2 is in a closed state, the controller 3 controls multiple air pumps 4 to work, and then inflates the inside of the sealing airbag 8 through the air pipe 5, so that the sealing airbag 8 swells and the gap between the inner baffle 6 and the outer baffle 7 is blocked to avoid the leakage of cold air. At the same time, when the door body 2 is in a closed state, the air pressure inside the sealing airbag 8 is monitored by the controller 3. When the air pressure drops, an alarm will be sounded to remind the staff that there is a leak.

[0028] When the door body 2 needs to be opened, the gas inside the sealing airbag 8 is released through the controller 3 to make the sealing airbag 8 deflate, and then the door body 2 can be opened.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
