Abstract
The hose joint includes a guide part provided in a nipple and provided to face an inner surface of a hose body having flexibility, a tightening member having a tapered surface provided to face an outer peripheral surface of the guide part and have a diameter which gradually becomes larger in an inserting direction of the hose body, a sleeve provided to be reciprocatable in each of the inserting direction of the hose body and an opposite hose pullout direction along the tightening member and be capable of elastic diameter expansion/contraction deformation in a radial direction, and an elastic member provided so as to press the sleeve in the hose pullout direction along the tapered surface.
Claims2
A hose joint comprising:
- a guide part provided in a nipple and provided to face an inner surface of a hose body having flexibility;
- a tightening member having a tapered surface provided to face an outer peripheral surface of the guide part and have a diameter which gradually becomes larger in an inserting direction of the hose body;
- a sleeve provided to be reciprocatable in each of the inserting direction of the hose body and an opposite hose pullout direction along the tightening member and be capable of elastic diameter expansion/contraction deformation in a radial direction;
- and
- an elastic member provided so as to press the sleeve in the hose pullout direction along the tapered surface, wherein
- the sleeve has a sleeve projection that bites into an outer surface of the hose body when a diameter of the sleeve is contracted,
- the guide part has a plurality of water shut-off members arranged from a far side to a rear side in the inserting direction of the hose body,
- the sleeve projection is disposed above the water shut-off member on the far side in the inserting direction of the hose body when connection of the hose body is completed, while being disposed above the water shut-off member on the rear side in the inserting direction of the hose body when an internal pressure of the hose body is high.
