发明名称 Hose coupling
摘要 A hose having a compressible wall which is adapted to be connected at one end thereof to a nozzle of a sprayer. The other end is attached to a stub pipe or stem extending from a tank of the sprayer which can contain a pressurized liquid which flows through the hose and is sprayed via the nozzle. The coupling provides a quick connection for the hose to the pipe stem and also allows the coupling/hose assembly to freely rotate 360° while remaining sealed. The coupling is an assembly of a nipple and a sleeve having a throat which compresses the hose wall and provides a retainer, retaining the end of the hose on the nipple. The nipple may have a flange which seats the integrated assembly of retainer, nipple, and hose on an end of the pipe stem with a portion of the nipple extending into the stem. An O-ring seal captured on the portion of the nipple which extends into the stem provides a seal between the nipple and the inner periphery of the stem. The stem has a tapered projection in the form of a barb. A C or E-spring clip has inward projection that extends through slots in the retainer. The spring clip is sprung apart as the assembly of retainer, nipple, and hose is seated on the pipe stem, and when seated springs back against a surface of the pipe stem, just below the barb to locate the inward projections of the spring clip, via the retainer slots, under the tapered portion and latches the assembly on the pipe stem. To disconnect or release the coupling, the spring clip is spread apart to free the assembly.
