TECHNICAL FIELD

[0001] The utility model relates to refrigerator sealing treatment technical field especially, relates to a refrigerator is with multiple sealing anti -drop seal strip and contains its refrigerator. BACKGROUND

[0002] The refrigerator door seal on the market is various, but most of them are difficult to install, easy to fall off and have uneven sealing effect.

[0003] Figure 1 And Figure 2 Two kinds of refrigerator door seals 300 on the market are shown, and these two kinds of door seals have a common defect that the installation process of the installation part 301 is relatively laborious, and even if the installation part 301 is laboriously installed on the refrigerator door body 303, the interference fit between the installation part 301 and the refrigerator door body 303 also loses some strength, so it is easy to fall off from the refrigerator door body 303.

[0004] In addition, Figure 1 The refrigerator door seal 300 also has the following defects: 1) due to the inclined arrangement of the two connecting ribs 306 on the inner side of the magnetic strip installation cavity 305, and the free end of the cabinet opening matching rib 307 is inclined towards the refrigerator door body 303, the sealing effect of the refrigerator cabinet opening (not shown in the figure) is not good; 2) the expansion rib between the cabinet opening matching rib 307 and the installation matching rib 309 is relatively thin, only two expansion ribs, namely the outer expansion rib 304 and the inner expansion rib 308, and after a period of use, the entire refrigerator door seal 300 is easy to lose effectiveness. Figure 2 The refrigerator door seal 300 also has the following defects: although the inner expansion rib 308 between the cabinet opening matching rib 307 and the installation matching rib 309 is provided with a sealing blade 318, it usually cannot be in contact with the refrigerator door body 303, and basically does not have a sealing effect. INVENTION CONTENTS

[0005] In order to solve the above-mentioned problems of the prior art, it would be advantageous to provide a refrigerator with a multiple sealing anti-falling seal strip and a refrigerator containing the same.

[0006] To achieve the above object, according to one aspect of the present application, a refrigerator multi-sealing anti-falling sealing strip is provided, which comprises cabinet opening matching ribs, middle supporting ribs and mounting matching ribs arranged in parallel, a magnetic strip mounting cavity and a transition supporting cavity are formed from outside to inside between the cabinet opening matching ribs and the middle supporting ribs, an outer side telescopic rib is formed between the middle supporting ribs and the mounting matching ribs, an inner side telescopic rib is formed between the cabinet opening matching ribs and the mounting matching ribs, and a mounting portion is formed on a side of the mounting matching rib away from the middle supporting rib, wherein the mounting portion has a pair of stay ribs arranged at intervals, a pair of oblique insertion ribs gradually tapering towards each other from the pair of stay ribs, and a pair of anti-falling blades formed at the ends of the pair of oblique insertion ribs and opening outwards, and wherein sealing blade one and sealing blade two are formed at the connections of the inner side telescopic rib with the cabinet opening matching rib and the mounting matching rib respectively, and sealing blade three is formed at an outer side end of the mounting matching rib.

[0007] In the present application, the installation of the whole mounting portion on the refrigerator door body becomes smooth and easy due to the installation of the mounting portion with the pair of oblique insertion ribs, the sealing blade one at the connection of the inner side telescopic rib with the cabinet opening matching rib and the sealing blade two at the connection of the inner side telescopic rib with the mounting matching rib, so that when the whole sealing strip is in a working state, the inner side telescopic rib is compressed so that the sealing blade one and the sealing blade two at both ends thereof are quickly forced to adhere to the refrigerator cabinet opening (specifically, the inner plastic part of the refrigerator cabinet opening) and the refrigerator door body (specifically, the matching door lining of the refrigerator door body) respectively, so that the inside of the refrigerator cabinet opening and the refrigerator door body is well sealed; the installation of the magnetic strip mounting cavity enables the whole sealing strip to be firmly attracted to the cabinet opening metal of the refrigerator cabinet opening by the magnetic strip, so that the outside of the refrigerator cabinet opening is sealed, and the installation of the transition supporting cavity enables the whole sealing strip to keep stable on the side of the refrigerator cabinet opening, so that it is tightly attached to the transition area between the cabinet opening metal and the inner cabinet opening plastic part, so that the middle of the refrigerator cabinet opening is sealed; the installation of the sealing blade three enables the mounting matching rib to be tightly attached to the door shell of the refrigerator door body, so that the outside of the refrigerator door body is sealed, and the installation of the mounting portion forms the middle of the refrigerator door body; the installation of the outer side telescopic rib and the inner side telescopic rib forms two seals from outside to inside of the whole sealing strip, and also forms an elastic connection between the refrigerator cabinet opening and the refrigerator door body, prolonging the service life of the whole sealing strip.
