The invention discloses a rocket interstage separation guiding pneumatic push rod, and relates to the technical field of spaceflight, and the rocket interstage separation guiding pneumatic push rod comprises a first push rod assembly and a second push rod assembly; the first push rod assembly comprises a base, an outer cylinder and an inner cylinder; one end of the base is communicated with the inflation system, and the other end of the base is connected with one end of the outer cylinder; an outer cylinder inner baffle ring is arranged on the inner side of the other end of the outer cylinder; the inner cylinder comprises an inner cylinder annular plate and an inner cylinder end face, and one end of the inner cylinder annular plate is connected with the inner cylinder end face. The inner cylinder is arranged in the outer cylinder, and the outer side of the inner cylinder annular plate is in sliding connection with the inner side of the outer cylinder; the second push rod assembly comprises a guide bolt, a locking nut, a connecting device and a thrust bracket; after extending, the side, away from the inner cylinder annular plate, of the end face of the inner cylinder is separated from the other end of the base, the other end of the inner cylinder annular plate is in limiting connection with the outer cylinder inner baffle ring, and one end of the guide bolt is separated from the inner cylinder and extends out of the outer cylinder. The pneumatic push rod can be guided by itself, and it can be guaranteed that the postures of the two separated substages are stable.

    本申请公开了一种火箭级间分离导向气动推杆,涉及航天技术领域,包括:第一推杆组件和第二推杆组件;第一推杆组件包括:底座、外筒和内筒;底座的一端与充气系统连通,底座的另一端与外筒的一端连接;外筒的另一端的内侧设置有外筒内挡环;内筒包括:内筒环板和内筒端面,内筒环板的一端与内筒端面连接;内筒设置于外筒内,且内筒环板的外侧与外筒的内侧滑动连接;第二推杆组件包括:导向插销、锁紧螺母、连接装置和止推支架;伸出后,内筒端面远离内筒环板的一侧和底座的另一端分离,内筒环板的另一端与外筒内挡环限位连接,导向插销的一端与内筒分离,且伸出至外筒外。本申请能够使气动推杆自带导向,能够保证分离后两个子级姿态稳定。
