Abstract

The utility model relates to the hidden structure of a pipe fitting crosslinked component. The pipe fitting is formed by crossing combination of a plurality of straight pipes and horizontal pipes, and the bottom end of each horizontal pipe is provided with an open groove to cause each straight pipe to pass through the inner side or end part of each horizontal pipe through each open groove and to be positioned on the inner side of each horizontal pipe. Positioning strips are provided and matched with the arranged positions of the horizontal pipes. Before the horizontal pipes do not combine with the straight pipes, the straight walls of the positioning strips and the outer walls of the straight pipes are connected and locked in series through combined components. Each horizontal pipe is inwards extended with a lower support body on a notch of the open groove, and two opposite inner walls of each horizontal pipes positioned above the lower support body project out of an upper blocking body by matching the height position of the straight wall of the positioning wall to cause the space between the upper blocking body and the lower support body to match with the height of the straight wall of the positioning strip. When the horizontal pipe and the straight pipe are crosslinked, the straight direction wall of the positioning strip causes the space between the upper blocking body and the lower support body to be embedded for fixing the horizontal pipe. Each combined component and each positioning strip are shielded and hidden by each horizontal pipe. Because combined components and the positioning strips are hidden in the horizontal pipes, the utility model has the advantages of shapely figure and good aesthetic feeling.
