Further, the extension part is in the shape of a sheet, and the sheet-shaped extension part and any two adjacent protrusions jointly form a U-shaped structure.

Further, the extension part is formed at the intersection of the side and the back of the airtight airbag, and is bent toward the back of the airtight airbag.

Further, the included angle between the extension part and the back surface of the sealed airbag is less than 90 degrees.

Further, the included angle between the extension part and the back surface of the sealed airbag is equal to 90 degrees.

Further, the angle between the extension part and the back surface of the sealed airbag is larger than 90 degrees.

Further, a connecting portion is provided on the back of the airtight airbag.

Further, the sealing airbag is provided with a second extension part opposite to the side where the extension part is provided.

Further, the outer surface of the sealed airbag is also provided with ribs.

The utility model also provides a refrigeration device, which includes a cold room, and the door body and the box body of the cold room are sealed by the above-mentioned multiple sealing members.

The utility model realizes multiple sealing by arranging the second sealing member on one side of the sealing air bag, and greatly improves the sealing effect. Moreover, the second sealing member is sealed by the closed cavity formed by the deformation of the protruding parts. Since each protruding part is independent and deforms independently during deformation, it can better fit the object to be sealed, and the sealing effect is particularly good. protrude.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the utility model and implement it, but the examples given are not intended to limit the utility model.

As shown in Figure 1, the multi-sealing member of the present utility model includes a sealing airbag 1, an extension part 2 extending outward from one side of the sealing airbag 1, and a plurality of protrusions 3 are arranged on one surface of the extension part 2, and the protrusions 3 An open cavity 4 is formed therebetween.

As shown in Figure 2, taking the application of the multi-sealing member of the present invention to a refrigerator as an example, the multi-sealing member of the present invention is embedded on the door body 9 of the refrigerator. When the door of the refrigerator is closed, the multi-sealing member is located in the refrigerator Between the door body 9 and the box body 10, at this time, in addition to sealing the air bag 1 to achieve sealing, the protruding part 3 arranged on the extension part 2 forms a closed cavity 8 through deformation, thereby realizing multiple sealing and achieving better sealing. Sealing effect.

As shown in Figure 1 and Figure 2, preferably, the extension part 2 of the multi-sealing member of the present invention is in the form of a sheet, and the sheet-shaped extension part 2 and any two adjacent protrusions 3 together form a U-shaped structure. This structure is more convenient for the deformation of the protruding part 3, so that the sealing effect is better. Wherein, a connecting portion 5 is provided on the back of the sealing airbag 1 , and the connecting portion 5 can be embedded in a groove on the refrigerator door 9 , so that the multiple sealing components of the present invention are installed on the refrigerator door 9 . The extension part 2 is formed at the intersection of the side surface and the back surface of the airtight airbag 1 , and is bent toward the back surface of the airtight airbag 1 . This structure enables the utility model to be arranged at the corner of the refrigerator door body 9, so that the circulation of the air is more hindered, so that the sealing effect is better. Preferably, the angle a between the extension part 2 and the back surface of the sealed airbag 1 is less than 90 degrees, so that the sealing member can fit the door body 9 better.
