The invention relates to an end wedge locking mechanism suitable for a standard drawer module. An end wedge and a screw mounting block are respectively accommodated near the end of a long rod chute. The screw mounting block is fixedly connected to the long rod chute. There are pre-embedded screws; the guide rail assembly is slidably connected to the long rod chute, the long tool rod is threaded on the long rod chute, the end is threaded with the end wedge through the embedded screw, and the front end is located outside the long rod chute. And be provided with the end cap stopper that abuts with long bar chute, the front end of this long tool rod is sheathed with compression spring, and the two ends of compression spring abut with long bar chute and end cap stopper respectively; The tool rod drives the end wedge to move to the front end of the standard drawer module through the embedded screw, and the end wedge is clamped and fixed with the guide rail assembly to lock the guide rail assembly. The invention can avoid the vibration amplification caused by the gap between the guide rail assembly and the long rod chute during the vibration process.
Description
technical field [0001] The invention belongs to the field of space application load systems for manned spaceflight engineering, in particular to an end wedge locking mechanism suitable for standard drawer modules. Background technique [0002] With the in-depth research and development of space, the development and utilization of space resources has become one of the important goals of the current competition among technological powers. my country's manned space station will become my country's future space science experiment base. The scientific experiment cabinet is loaded in the cabin section of the space station and is a platform for scientific experiments; the load drawer can expand the function of the experimental cabinet, which is of great significance to space science experiments. The quick-release standard drawer module is usually equipped with sliding guide rails, and there is a gap between the guide rail and the chute. During the mechanical test of the guide rail...
