发明名称 Pipe fitting
摘要 A pipe fitting for a flexible pipe such as used in lawn sprinkler systems. The fitting includes a pipe sealing portion and a pipe gripping portion. The pipe sealing portion has a smooth, seamless cylindrical surface to form a strong, watertight seal with the inner surface of the pipe. The pipe gripping portion is spaced from the sealing portion and includes a cylindrical surface with two rows of spikes extending axially along it. The rows are spaced 180 degrees from each other about the cylindrical surface and the cylindrical surface of the gripping portion has a smaller diameter than the cylindrical surface of the sealing portion. In use, the flexible pipe is forced to assume a substantially elliptical shape as it passes over the rows of progressively taller spikes. The pipe can then be crimped if desired to embed the spikes into the wall of the pipe and preferably to drive at least some of the spikes completely through the pipe wall.
