Mouth bracket with rubber hose , and method of manufacturing the mouth bracket with rubber hose

摘要

PROBLEM TO BE SOLVED: To provide a rubber hose with a mouthpiece capable of easily and surely locking the mouthpiece.;SOLUTION: A stop ring 7 is protrudingly formed in the outer peripheral surface of the mouthpiece 3. A hose body 2 is formed so as to cover the stop ring 7. The winding diameters of a reinforcing fiber layer 4a and a spiral wire 5 in the position displaced from the stop ring 7 are set to be a smaller diameter than the outer diameter of the stop ring 7. A code 6 for locking is wound in the outer peripheral side more than the reinforcing fiber layer 4a and the distal end side more than the stop ring 7. The code 6 for locking regulates the increase of the diameter of the reinforcing fiber layer 4a and the spiral wire 5. The reinforcing fiber layer 4a and the spiral wire 5 catch the stop ring 7 from the distal end side via rubber. The mouthpiece 3 is prevented from coming off from the hose body 2 and locked.;COPYRIGHT: (C)2012,JPO&INPIT
