The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
As shown in fig. 1 and 2, the present embodiment provides a mounting rack for an airborne electronic equipment chassis, which includes a bottom plate 1 and a buffer pad 2, wherein the top of the bottom plate 1 is fixedly connected with opposite side plates 3, and a middle plate 4 is fixedly connected between the two side plates 3. The intermediate plate 4 is provided with a connector plug 5 corresponding to the connector socket of the chassis.
