CONNECTION STRUCTURE OF COMPOSITE RESIN PIPE AND WATER SUPPLY TOOL, AND SHOWER HEAD

摘要

PROBLEM TO BE SOLVED: To provide a connection structure of a composite resin pipe and water supply tool, and a shower head, in which a connection tool does not expose outside, having a simple configuration, requires less number of parts, and further, a connection operation is highly easy without a risk of loosening, which enables reduction in cost.;MEANS FOR SOLVING THE PROBLEM: An insertion end 25 is provided on one composite resin pipe 23, and an insertion receiving port 33 into which the insertion end is inserted is provided on the other composite resin pipe 3. Locking recesses 29, 36 are formed at the positions at a predefined distance from each of the open ends on an inner surface of the two pipes. A connection tool 5 is provided over insides of the two pipes so as to connect the two pipes. The connection tool includes: a center ring part 51; a plurality of elastically-deformable arms 53, 54 each extending in an axial direction from both ends of the center ring part; and locking hooks 55, 56 each formed at tip end of the arms. The two pipe are connected via the connection tool by having the locking hooks lock with the locking recesses of the two pipes.;SELECTED DRAWING: Figure 9;COPYRIGHT: (C)2019,JPO&INPIT
