The invention discloses a fine-diameter pipe cabin-penetrating sealing device with high-reliability sealing in a dynamic environment. The fine-diameter pipe cabin-penetrating sealing device comprises a sealing cover plate, a sealing seat, a nut, a pressing block, a rubber sealing block, a cushion block and a fine-diameter pipe structure. The sealing reliability is high; by utilizing the characteristics of high material strength and high modulus of the sealing seat and combining the matching design of the structure size chains of the sealing block, the sealing seat and the like, the contact stress change of each sealing surface in a dynamic environment is small, and the sealing effect of the small-diameter pipe cabin-penetrating sealing structure in the dynamic environment meets the design requirement; the leak rate of the cabin penetrating part to non-corrosive gas is not greater than 10 <-6 > Pa.m < 3 >/s magnitude; the long-time storage condition is adapted; by reasonably selecting a rubber sealing block ma
