Abstract

The invention provides a connecting device suitable for an extra-cabin handle of a spacecraft. The connecting device comprises a handle B, a guide driving pin B, an anti-looseness device, a clamping ring, a cover plate, a shell B, a handle safety catch, a handle pressing block, a spring pre-tightening block, pre-tightening springs, a spring plug, a handle safety catch driving spring, a lead screw B, a handle safety catch release locking rod, a handle safety catch release locking rod connecting block, handle safety catch release locking rod triggering rods, small springs, an anti-looseness device shell, an anti-looseness spring, an anti-looseness ball and a lead screw B check ring, and a peripheral device is the extra-cabin handle. Guided installation, reliable fixation, accurate pointing and overload protection of the extra-cabin handle and the connecting device are achieved, and therefore positions are provided for installing exposed load devices or other spaceflight devices on the extra-cabin handle.

Description

technical field [0001] The invention belongs to the field of space application equipment, and in particular relates to a connecting device suitable for an outer handle of a space vehicle. Background technique [0002] Space vehicles such as space stations and manned spacecraft have arranged a large number of handles for astronauts on the outer wall of the cabin to facilitate the movement and fixation of astronauts when they leave the cabin. If some handles are used to fix small exposed loads outside the cabin, the space vehicle will be greatly expanded. exposure test capabilities. At present, the International Space Station has used the external handle to fix the material exposure experiment box to conduct long-term material exposure experiments. [0003] However, for the handle outside the cabin, the connecting device in the prior art cannot automatically capture the handle outside the cabin, and has poor self-locking function and low reliability.
