Abstract: An adjustable housing frame with industrial rails includes a fixed plate, two movable plates and at least two positioning pieces. A front side of the fixed plate is provided with a rail. Both ends of the fixed plate are provided with two opposite rails respectively. Each set if the two opposite rails is provided with at least one positioning hole. One of the two movable plates is provided in the two rails at one end of the fixed plate, and the other movable plate is provided in the two rails at the other end of the fixed plate. Edges of the two movable plates are provided with a plurality of positioning troughs. The two positioning pieces pass through the two positioning holes and extend into the positioning troughs respectively. The two positioning pieces are stopped on inner walls of the positioning trough.

Abstract: A fixing device is provided on a casing of an industrial communication product, which includes a fixing plate, at least one elastic piece with an end, a pulling element, and an elastic element. The fixing plate is provided with at least two first connecting portions. The elastic piece is disposed corresponding to the first connecting portions. The pulling element is provided with two stoppers and at least two second connecting portions. The two second connecting portions are slidingly connected to the two first connecting portions. The pulling element is movable between a first position and a second position; wherein when at the first position, the end of the elastic piece abuts the second connecting portion; when at the second position, the end of the elastic piece is stopped by the second connecting portion, and thereby unlocking the industrial communication product, thus making the product accessible for repair and testing.
