Extrusion type door gasket structure

Abstract

The invention discloses an extrusion type door gasket structure, and relates to the technical field of door gasket structures. The structure comprises a main air bag and a buckle; the main air bag isof a breathable strip-shaped structure; the main air bag is provided with a plurality of layers of small air bags; the strip-shaped buckle is fixed to one end of the main air bag; barb structures aresymmetrically arranged at the two sides of the buckle; the buckle is of the hollow air bag structure; the height of the small air bags is a quarter to a half of that of the main air bag; the ratio X of the width to the height of the main air bag is not smaller than 3 and not larger than 4.5; the buckle is matched with an inverted omega shaped groove formed in one end face of a refrigerator door body; the main air bag is in pressing fit between the refrigerator door body and a box body liner opening. The multiple layers of small air bags are arranged inside the main air bag, the height of the small air bags is a quarter to a half of that of the main air bag, the main air bag is clamped to the refrigerator door body through the buckle, the weight of the refrigerator door body extrudes the main air bag, and the main air bag is in pressing fit between the refrigerator door body and a box body liner opening, so that the sealing heat preservation effect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of door seal structures, and particularly relates to an extrusion type door seal structure. Background technique [0002] Energy saving of household appliances is an important part of refrigerator design. As a home appliance, the freezer is an indispensable part of daily life, and the number of users is increasing day by day. Therefore, the energy saving of the freezer is particularly important. The existing freezer door seal structure has a general sealing effect and a poor heat insulation effect, which results in rapid heat dissipation of the cold in the refrigerator, which affects food preservation and freezing. [0003] The present invention is devoted to researching an extrusion type door seal structure, which is used to solve the problems of poor sealing effect and poor heat insulation effect of the existing freezer door seal. Summary of the invention [0004] The object of the present invention is to provid...

Problems solved by technology

[0004] The purpose of the present invention is to provide a squeeze-type door seal structure. The main airbag is provided with multiple layers of small airbags and the height of the small airbags accounts for 1 / 4-1 / 2 of the height of the main airbag, and the main airbag is snapped on the On the freezer door body, the self-weight of the freezer door body squeezes the main airbag, so that the main airbag is pressed between the freezer door body and the box liner, which plays a role of sealing and heat preservation, and solves the problem of poor sealing effect of the existing freezer door seals and The problem of poor insulation
