WATER DISCHARGE DEVICE

Abstract

Disclosed is a water discharge device (1) provided with a device body (2) and a connector (4) and adapted to be attached to a feedwater pipe (6). The water discharge device comprises fixing means (8) for fixing the device body to the connector at a given installation position. The connector has a feedwater-pipe-joining portion (4a) adapted to be joined to the feedwater pipe, and a connector-side engaging thread portion (4b), and the device body has a body-side engaging thread portion (14) positioned in such a manner as to be engaged with the connector-side engaging thread portion once during an operation of attaching the device body to the connector, and located beyond the connector-side engaging thread portion after the device body is fixed at the installation position. The water discharge device of the present invention can reliably prevent falling-off of the device body.

Claims

1. A water discharge device provided with a device body and a connector and adapted to be attached to a feedwater pipe, comprising: fixing means for fixing said device body to said connector at a given installation position,said connector has a feedwater-pipe joining portion adapted to be joined to said feedwater pipe, and a connector-side engaging thread portion; andsaid device body has a body-side engaging thread portion positioned in such a manner as to be engaged with said connector-side engaging thread portion once during an operation of attaching said device body to said connector, and located beyond said connector-side engaging thread portion after said device body is fixed at said installation position.

2. The water discharge device according to claim 1, further including sealing means adapted to provide water-tightness between said device body and said connector, said sealing means being adapted to lose said water-tightness when said device body is displaced from said installation position.

3. The water discharge device according to claim 1, wherein said fixing means is a setscrew which is screwed in said device body and adapted to allow a tip thereof to be in contact with said connector.

4. The water discharge device according to claim 2, wherein said fixing means is a setscrew which is screwed in said device body and adapted to allow a tip thereof to be in contact with said connector.

5. The water discharge device according to claim 1, wherein said fixing means is a pair of fixing thread portions formed, respectively, in said device body and said connector, and adapted to be threaded with each other.

6. The water discharge device according to claim 2, wherein said fixing means is a pair of fixing thread portions formed, respectively, in said device body and said connector, and adapted to be threaded with each other.

7. The water discharge device according to claim 5, wherein either one of said body-side engaging thread portion and said connector-side engaging thread portion additionally serves as either one of said pair of fixing thread portions.

8. The water discharge device according to claim 6, wherein either one of said body-side engaging thread portion and said connector-side engaging thread portion additionally serves as either one of said pair of fixing thread portions.

9. The water discharge device according to claim 7, wherein said body-side engaging thread portion additionally serves as the fixing thread portion formed in said device body, said fixing thread portion of said device body having a length less than a distance between said connector-side engaging thread portion and the fixing thread portion formed in said connector and located on the proximal side of said connector relative to said connector-side engaging thread portion.

10. The water discharge device according to claim 8, wherein said body-side engaging thread portion additionally serves as the fixing thread portion formed in said device body, said fixing thread portion of said device body having a length less than a distance between said connector-side engaging thread portion and the fixing thread portion formed in said connector and located on the proximal side of said connector relative to said connector-side engaging thread portion.
