The utility model discloses a door sealing strip. The invention relates to the field of refrigeration equipment accessories. An airbag assembly comprising an airbag, the magnetic strip chamber is composed of a clamping part; The method is characterized in that the method is characterized by comprising, an outer cavity air bag is arranged on one side of the magnetic strip chamber; a deformation space is still reserved at the joint of the air bag and the magnetic strip chamber; the space is wrapped in the outer cavity air bag; Therefore, when the refrigeration cabinet door is closed, the refrigeration cabinet door is closed;, When the air bag is extruded, deformation of the air bag is not affected, meanwhile, a gap between the magnetic strip chamber and the refrigerated cabinet is filled with the outer cavity air bag, the risk of cold leakage between the magnetic strip chamber and the refrigerated cabinet is reduced, meanwhile, due to the fact that the outer cavity air bag is located onone side of the magnetic strip chamber and overlaps with the magnetic strip chamber, the thickness of the cross section of the door seal is increased, and the heat insulation effect is improved.
