Tool-free linkage locking and pulling device for LRM

Abstract

The invention discloses a tool-free linkage locking and pulling device for an LRM, which can take plugging, pulling and locking into consideration and achieve tool-free operation. According to the technical scheme, a spring bolt is connected with an LRM case rib through a pulling block at the tail end of a pulling rocker arm handle, under the action of external force F, the spring bolt is in linkage in the displacement direction of the pulling block, and in the process that an LRM electronic module is inserted into the LRM case, the pulling rocker arm handle is manually operated with the help of pushing force of a shifting fork on a rotating pair, a rotating shaft in a lug shaft hole of an elbow fork is used as a fulcrum, the lever is linked with a roller and the shifting fork, and the roller is shifted left and right in a shifting groove of the LRM case by utilizing a crank force arm on the fulcrum of the pulling rocker arm handle to drive a locking device to apply push-pull pressure, so that locking or unlocking of push-in / pull-out switching of the LRM in a locking slot of the LRM is realized. The pulling rocker arm handle can be directly operated and locked to complete insertion, pulling and locking of the electronic module, tools such as a screwdriver are not needed, and the operation is convenient.

Description

technical field [0001] The invention relates to a locking and pulling out device mainly used for LRM (Line Replaceable Module) electronic modules with plugging and locking functions. Background technique [0002] With the development of science and technology and the increasingly complex application environment, electronic equipment is developing in the direction of precision, automation, scale, and miniaturization. There are more and more applications of highly integrated field-replaceable electronic modules LRM. The field-replaceable module LRM of the new generation of avionics is a module that installs high-speed integrated circuits VHSIC (VeryHighSpeedIntegratedCircuits) and very large-scale integrated circuits (VLSI) with independent functions. [0003] LRM modules generally have the same standard form factor and mechatronic interface, and must have the ability to be directly replaced at the mission site. The so-called scene refers to the actual use environment of the ...
