Space docking repeated locking device

Abstract

The invention discloses a space docking repeated locking device, and relates to the technical field of locking devices. Limiting pins are mounted on a frame body to limit the positions of locking hooks; the two ends of each torsional spring are respectively mounted on the frame body and the corresponding locking hook to apply certain pre-tightening force to the corresponding locking hook so as to ensure that the locking hooks can return when a locking mechanism is from a locked state to an unlocked state; the locking hooks are mounted on pin shafts B; the pin shafts B are mounted on the frame body; the pin shafts B are fixed to the frame body through flat head screws A; and a sleeve A and a sleeve B are respectively mounted at the two ends of each pin shaft B so as to limit axial swinging of the locking hooks. According to the space docking repeated locking device, locking can be performed through two symmetrical locking hooks and the pin shafts; the locking force is great; the connecting strength can be ensured; the position locking of the locking hooks can be realized by utilizing a crank mechanism; the locking hooks are prevented from moving up and down when the locking is performed; and the reliability is high, the connecting strength is high, and repeated locking can be realized. Guide grooves of the frame body have the effects of guiding and positioning on the pin shafts at a passive end; and limiting sliding blocks are enabled to reach pointed positions accurately to lock the positions of the locking hooks.

Description

technical field [0001] The invention relates to a space docking repetitive locking device, which belongs to the technical field of locking devices. Background technique [0002] With the continuous deepening of space exploration, development and utilization, the goal of human beings to establish space laboratories, relay stations and planetary bases is gradually being realized. As the main tools for exploring space, spaceships, space shuttles and space laboratories are the main representatives of operating platforms currently in orbit. In order to make the connection between the spacecraft or between the spacecraft and the space station reliable, structural locks are usually designed in the space docking mechanism. [0003] At present, the commonly used locking device in the aerospace field is a pressing mechanism composed of a pressing rod and a pyrotechnic cutter. Their principles determine that the work cannot be repeated, and cannot meet the requirements of repeated loc...
