The invention discloses an internal shrink gradual change inflatable docking apparatus for space. The apparatus comprises a docking pipeline, the docking pipeline comprises an external pipe and an internal pipe which are coaxial, an interlayer space is arranged between the external pipe and the internal pipe, the first end of the docking pipeline is connected with a connection flange, the second ends of the external pipe and the internal pipe are in enclosed connection, multiple groups of annular blocks are successively arranged from the second end to the first end on the inner wall of the internal pipe and intervals are gradually changed, each group of annular blocks is composed of two closely arranged annular blocks, tubular elastomers are installed between two adjacent groups of annular blocks respectively in a sealing mode, the tightness of the multiple elastomers is the same or basically the same, and the pipe wall of the internal pipe disposed between an initial group of annular blocks and a tail group of annular blocks is provided with multiple through holes which are communicated from the inside to the outside. According to the invention, a mode of installing the elastomers on the internal pipe of the docking pipeline in a sealing manner is employed so that the stability of the whole docking apparatus after docking is enhanced, reliable operation of a control object is facilitated, and the adaptation scope of the docking apparatus is expanded.
