▎ 摘　　要

NOVELTY - The guide rail slider device applied to a space probe, has guide rail mechanism (1) which is convex; and a sliding block (2), which can be slidingly set on the guide rail mechanism. The sliding block is provided with lubricating material storage chamber (3). The sliding block and contact surface of the guide rail mechanism are covered with molybdenum disulfide composite solid film. The bottom part of the guide rail mechanism is fixedly connected with the machine body of a space probe. The top part of the sliding block is used for fixed installation of maintenance and repairing device. USE - Guide rail slider device applied to a space probe. ADVANTAGE - The structure is simple and reasonable, the service life is long, the lubricating effect is good, it is wearable, and the bearing capacity is strong. DESCRIPTION OF DRAWING(S) - The drawing shows a three-dimensional schematic structural diagram of a guide rail slider device applied to a space detector. 1Guide rail mechanism 2Sliding block 3Lubricating material storage chamber
