Connection device for skirting board shaped radiators

The invention discloses a connection device for a combined pipeline of skirting board shaped radiators. The connection device for the combined pipeline of the skirting board shaped radiators comprises a double nipple and a lined pipe sleeve, wherein an end of the lined pipe sleeve abuts against a limiting bayonet arranged in the double nipple; an end of a first seal ring wraps around the lined pipe sleeve and the other end of the first seal ring abuts tightly against a pipe opening of a connection hose; an outer thread of an end of the double nipple is provided with a second seal ring, the outer thread is matched with an inner thread located at an pipe opening of the pipeline on the inner side of a radiating panel, and the second seal ring is matched with an oblique opening formed in the pipe opening of the pipeline. According to the connection device for the combined pipeline of the skirting board shaped radiators, a lined pipe sleeve is arranged to support the seal rings, so that the seal rings are restricted in inward deformation; the double nipple is internally provided with the limiting bayonet, so that it is guaranteed that the lined pipe sleeve cannot flow into the pipeline to cause clogging under the external force extrusion; the oblique opening is formed in the pipe opening of the pipeline of the radiating panel by processing, so that seal ring damage caused by extrusion deformation is avoided, and the service life of the seal rings is prolonged.
