An in-orbit material experiment box mechanism

Abstract

The invention relates to an on-orbit material experiment box mechanism, comprising an experiment box, an on-rail mounting bracket, a locking release mechanism and a locking plate, the on-rail mounting bracket is fixedly installed on the outer platform of an on-orbit spacecraft; the locking plate is fixed Installed on the rail mounting bracket; the side wall of the test box is provided with an assembly cavity with an opening; the locking release mechanism is installed in the assembly cavity; the locking release mechanism is provided with a locking protrusion, and the locking protrusion is movable Installed at the opening of the assembly cavity, the locking plate is provided with a locking groove, and the locking protrusion matches the locking groove; wherein, the locking protrusion protrudes or retracts into the assembly cavity, so that the locking protrusion The lifting plate is snapped into or separated from the locking groove to realize the locking or releasing of the locking plate and the experiment box. The invention realizes the on-orbit repeatable locking and releasing of the experiment box; the locking and releasing are realized through the clamping and separation of the locking protrusion and the locking groove, the structure is simple, the operation is simple, and it is convenient for the astronauts to complete the operation on the orbit Locking and releasing of the test box.

Description

technical field [0001] The invention relates to a material exposure experiment in a cabin space environment, in particular to an on-orbit material experiment box mechanism. Background technique [0002] In order to meet the needs of future deep space exploration, it is of far-reaching significance to study the in-orbit service behavior of materials in the field of basic disciplines, and to study the in-orbit characteristics and changes of materials. During the missions of the Soviet Space Station and the International Space Station, on-orbit exposure tests of metals, non-metals and other materials have been verified many times, and significant scientific research results have been achieved. However, my country is still in its infancy in terms of space material exposure. In order to meet the mission requirements of material space exposure, it is urgent to involve an experiment that can be repeatedly installed on the material to be exposed, can be locked and released as a whol...
