Embodiment 1

[0045] The invention provides a combined sealing structure, such as Figure 2-Figure 8 As shown, it includes: a door body 3 and a gasket 1, the gasket 1 is supported under the door body 3, and the gasket 1 has a variable pressure chamber 11; a plurality of first support blocks 4 are arranged in the gasket 1 and have supporting The upper wall of the gasket 1 makes the upper wall of the gasket 1 close to the first position of the door body 3, and the second position away from the upper wall of the gasket 1; the driving mechanism is located inside the gasket 1 or outside the gasket 1, and the driving mechanism The output end is used to control the first support block 4 to switch between the first position and the second position. Wherein, the sealing pad 1 is externally connected with an air pump 12. When the sealing pad 1 is required to seal the door body 3, in addition to the air pump 12 inflating and pressurizing the variable pressure chamber 11, the plurality of first support...

Embodiment 2

[0056] This embodiment provides a cold storage door, including: a door body 3, which is slidably connected to the door frame; the combined sealing structure of any of the above schemes includes a gasket 1, and the gasket 1 is supported under the door body 3, and the door body 3 When closed, the upper wall of the gasket 1 is supported by the support block and is in contact with the bottom of the door body 3; when the door body 3 slides, the support block is removed from the upper wall of the gasket 1 to support.

[0057] The combined sealing structure also includes: a plurality of second support blocks, the second support block has a support position for supporting the upper wall of the gasket 1 so that the upper wall of the gasket 1 is close to the door body 3, and a relaxed position away from the upper wall of the gasket 1 , a plurality of first support blocks 4 form a first support unit, and a plurality of second support blocks form a second support unit. The first supportin...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a combined sealing structure and a cold storage door. Background technique [0002] Cold storage is mainly used for constant temperature storage of food, dairy products, meat, aquatic products, poultry, fruits and vegetables, cold drinks, flowers, green plants, tea, medicines, chemical raw materials, electronic instruments, etc. At present, the cold storage adopts horizontal sliding doors. The top of the sliding door is generally slid and hoisted on the lintel, and the bottom of the sliding door is sealed with the ground by a sealing strip. The friction of the ground is high, which makes the sliding door difficult to move and easy to be damaged; if the pressure between the sealing strip and the ground is too loose, there is likely to be a gap between the sealing strip and the ground, resulting in poor insulation of the cold storage. [0003] The Chinese invention...
