Abstract: A base and a module for node modules are disclosed. The base includes a first container, a second container, and a rotation portion connected with the first container and the second container respectively, wherein the first container and the second container are substantially the same and adjacent to each other. When the first container is rotated forward to the second container, the first container is stacked on the second container, and the total height of the first container and the second container is 2U.

Abstract: A coupling structure comprises a casing disposed with a bottom plate, a first side plate and a second side plate; the first side plate is disposed with at least one retaining portion; said retaining portion is disposed with a movable end and a retaining unit; the retaining unit is projected out from said first side plate toward an inner part of the casing; at least one actuating component is corresponding to the retaining portion; the actuating component is disposed with a cylindrical body and guide groove; the guide groove surrounds the cylindrical body; the cylindrical body is pivotally coupled to first side plate; the guide groove accepts the movable end.

Abstract: The assembling structure for electronic module comprise a case and a side frame, the characteristic is the case fixed on the base frame of the assembling structure by two front pivots and the case pivoted thereon. Besides, the side frame is installed adjacent to the case. In addition, the case and the side frame respectively include a plurality of locking holes, the side frame further including a locking controller with a first latch and a second latch corresponding to the locking holes, thereby locking the case at a horizontal and oblique position.
