Embodiment Construction

[0014] refer to Figure 1-Figure 4 . In the embodiment described below, an airborne electronic module plug-in locking puller includes: a lifting rod 1 with a horizontal fork elbow, a support 2 with a right-angle elbow, and a fork Wedge block 3 of ear spring groove. The shaft sleeve 7 with the torsion spring 8 passed through the fork eye hole on the horizontal lug elbow of the puller 1, and the wedge block 3 is hinged together by the rotating shaft 5 and the washer 6 inserted into the sleeve 7, and the puller 1. It is close to the seat body of the support 2 in the vertical direction, and the lock on the free end is locked on the locking hook at the bottom of the support 2; into the fork ear spring groove on the top of wedge block 3, and the wedge-shaped conical surface on the top of wedge block 3 protrudes through the opening on the fork ear spring groove to form a moving pair linked by lever 1; The rotation forms the rotating pair and the moving pair controlled by the torsi...

Abstract

The invention discloses an airborne electronic module plugging locking puller and aims to provide an airborne tool with good reliability and compatibility. The airborne electronic module plugging locking puller is achieved by the following technical solution that a shaft sleeve (7) sleeved with a torsion spring (8) passes through a lug hole in a horizontal lug elbow of a pull rod (1), a wedge-shaped block (3) is hinged together by a rotating shaft (5) inserted into the shaft sleeve (7) and a washer (6), the pull rod is close to a seat body of a support seat (2) in a vertical direction, and a free end upper lock is locked to a locking hook on a bottom end of the support seat (2). A vertical spring seat at a lower side of a wedge-shaped block lug spring groove pushes a compression spring (4)into a lug spring groove on the top of the wedge-shaped block, a wedge-shaped tapered surface at the top of the wedge-shaped block extends out of an opening in the lug spring groove, and a moving pair linked with a lever of the pull rod is formed. The pull rod rotates around the rotating shaft to form a rotating pair and the moving pair controlled by the torsion spring (8).

Description

technical field [0001] The invention relates to a tool-free maintenance puller for an airborne electronic module, in particular to a puller for fast plug-in, pull-out and locking. Background technique [0002] At present, most of the replaceable electronic module LRM modules on the electronic equipment rack use a puller and a locking device, and the puller and the locking device are separated. The puller is installed on the front panel of the LRM module, and the locking device is installed on the rib on the side of the module. Through the cooperation of the two, the quick installation and removal of the LRM module on the rack can be realized. But this kind of puller can only play the function of initial locking and limiting of the module, and the locking of the module also needs to be equipped with a locking device or screwed on the equipment rack. This kind of puller makes plugging and unplugging the module unable to take into account the problem of module locking, and req...
