The invention discloses a combined sealing structure and a refrigerator door. The combined sealing structure comprises a door body, a sealing gasket, multiple first supporting blocks and a driving mechanism. The sealing gasket is supported below the door body, and a variable pressure cavity is arranged in the sealing gasket; the first supporting blocks are arranged in the sealing gasket and are provided with a first position for supporting the upper wall of the sealing gasket to enable the upper wall of the sealing gasket to cling to the door body and a second position far away from the upperwall of the sealing gasket; and the driving mechanism is arranged in the sealing gasket or outside the sealing gasket, and the output end of the driving mechanism is used for controlling the first supporting blocks to be switched between the first position and the second position. Multi-point support formed by the multiple first supporting blocks enables the upper wall of the sealing gasket to have a plurality of deformation points, the upper wall of the sealing gasket is more likely to deform, meanwhile, the upper wall of the sealing gasket is stressed to produce tensile deformation around the supporting points formed by the supporting blocks, so that the upper wall of the sealing gasket around the supporting points is thinner and can be more easily supported and expanded by air, and thesealing effect is better.
本发明公开了一种组合式密封结构及冷库门，门体和密封垫，密封垫支撑于门体下方，密封垫内具有变压腔；多个第一支撑块，设于密封垫内，具有支撑密封垫上壁使密封垫上壁紧贴门体的第一位置，以及远离密封垫上壁的第二位置；驱动机构，设于密封垫内或密封垫外部，驱动机构输出端用于控制第一支撑块在第一位置与第二位置之间切换。多个第一支撑块形成的多点支撑，导致密封垫上壁出现多个形变点密封垫上壁更容易发生形变，同时在支撑块构成的支撑点周围，密封垫上壁受力发生拉伸形变，导致支撑点周围的密封垫上壁变薄，更容易受空气支撑膨胀密封效果更好。
