2. Description of the Related Art Conventionally, a so-called stop water in which the flow rate of fluid such as hot water or cold water discharged from a discharge port provided at the tip of a conduit can be adjusted by a handle provided in the vicinity of the discharge port. The stopper metal fittings are, for example, Shoukai 64-2417.
No. 1 publication. With such a stopper water faucet, it is convenient to operate the handle without extending the hand so that the discharge port can be easily opened and closed without wetting the hand or clothes. In addition, even when hot water is being discharged, it is safe because it can be closed without touching the hot water.

However, the conduit (water discharge pipe) of the stopper water faucet fitting described in the above-mentioned conventional example is fixed to the hand washing bowl or the like in a protruding manner, and its discharge port is fixed to the conduit. Is attached to. Therefore, the water can be discharged only toward a predetermined position such as a hand washing bowl. However, in a relatively wide sink or the like, it would be more convenient if such a stopper water faucet fitting is configured so that the angle of its outlet can be changed with respect to the conduit.

[0004]

By the way, conventionally, as shown in FIG. 8, for example, when the angle of the discharge port 8 attached to the tip end portion 7 of the conduit 6 of the stopper water faucet metal fitting 1 is variable, A work hole 52 is formed in a part of the rotary casing 36 to which the discharge port 8 is integrally attached, a tool is inserted into the work hole 52 from the work hole 52, and the work hole 52 is fixed in the leading casing 31. A retaining member 54 such as a retaining ring is fitted in the circumferential groove 34 of the pivot 32 so that the bearing portion (shaft hole 50) formed on the vertical wall 49 of the rotatable casing 36 is rotatably retained. It was Therefore, the working hole 52 formed in the rotary casing 36 needs to be closed by the blind lid 55 after the rotary casing 36 is attached, which requires a lot of labor for the assembling work and a large number of parts. There was a difficulty that

The present invention has been made in view of the above circumstances, and an object of the present invention is to improve the assemblability of the discharge port in the stopper faucet metal fitting that can change the angle of the discharge port. .

[0006]

According to the present invention, a discharge port for discharging a fluid to the outside is rotatably attached to the tip of a conduit attached to a supply port for supplying a fluid, and the discharge port is provided. The handle for variably adjusting the flow rate of the fluid discharged from the stopper water stopper metal fitting provided near the discharge port has the following means for achieving the above-mentioned problems. Is configured.

That is, a leading casing is fixed to the tip of the conduit, and a flow rate adjusting valve for adjusting the flow rate of the fluid discharged from the discharge port is housed inside the casing. While being operated by a handle rotatably attached to one end of the tipping casing, a turning casing is rotatably fitted to the other end of the tipping casing, and the turning casing is integrated with the discharge port. By screwing the retaining ring of
The retaining ring is fitted into a circumferential groove formed at the tip of a pivot that is fixedly supported on the other end of the pre-attached casing, and the rotating casing having the discharge port is retained in the pivot. And so as to be rotatable about its pivot axis.

[0008]

According to the above construction, the rotary casing is fitted to the other end of the front-end casing, and a retaining ring integrated with the discharge port is screwed into the rotary casing, whereby the rotary casing is fixed to the other end side of the front-end casing. If the retaining ring is fitted in the circumferential groove formed at the tip of the supported pivot, the rotating casing with the discharge port attached is in the state of retaining with respect to the pivot, and It is attached so as to be rotatable around. In this way, a rotatable casing having a small number of parts and having a discharge port can be attached to the pre-attachment casing very easily without performing troublesome pre-processing.

EXAMPLES The present invention will be described in detail below based on examples. The stopcock fitting 1 is shown in FIG.
Is rotatably attached to the supply port 5 provided in the sink 3, and the discharge port 8 provided in the tip portion 7 of the conduit 6 thereof.
However, a handle 9 that is rotatably attached to the conduit 6 and that variably adjusts the flow rate of the fluid discharged from the discharge port 8 is provided near the discharge port 8. That is, the conduit 6 is rotatable, the discharge port 8 provided at the tip portion 7 thereof can be moved to an arbitrary position, and the angle of the discharge port 8 itself can also be arbitrarily changed. Moreover, the flow rate of the fluid discharged from the discharge port 8 can be variably adjusted by the handle 9 provided corresponding to the discharge port 8. Therefore, when such a stopper water faucet metal fitting 1 is provided on a relatively wide sink 3, the handle 9 can be operated without extending the hand so that the hand and clothes can be easily wetted without spouting. 8 can be opened and closed, and even when hot hot water is being discharged, it can be closed without touching the hot water, which is extremely convenient and safe.

The tip portion 7 of the stopper water faucet fitting 1 is shown in FIG.
, A flow rate adjusting valve 29 for adjusting the flow rate of the fluid discharged from the discharge port 8 is provided at the tip portion 7 of the conduit 6.
It is housed in a leading casing 31 which is fixed so as to intersect with each other in a letter shape. A rotating casing 36 having a discharge port 6 is attached to one end thereof, and a handle 9 is attached to the other end thereof so as to be rotatable. ing.

The flow rate adjusting valve 29 housed in the pre-installed casing 31 is relatively slidably rotated by a support shaft 42 which is fixed to a handle 9 rotatably attached to one end of the pre-mounted casing 31 and rotated. The disc member 43, 44 has a pair of holes, and the flow rate of the fluid discharged from the discharge port 8 can be variably adjusted by adjusting the size of the holes. More specifically, the support shaft 42 is rotatably supported by a bearing portion 45 fixed in the front casing 31, the handle 9 is fixed to the outer end by a screw member 46, and the support shaft 42 is supported on the inner end. One disk member 43 with a hole is fixed via the member, and the disk member 44 with another hole that coaxially slidably contacts the disk member 43 with a hole is formed at the rear end of the bearing portion 45. It is fixed to the support.

The disk members 43 and 44 with both holes are
It is made of ceramics and has good durability.
Although not shown, there is a corresponding fan-shaped flow rate adjusting hole, and the one disk member 43 with a hole that is rotated by the handle 9 is rotated with respect to the flow rate adjusting hole of the other fixed disk member 44 with a hole. By the relative rotational displacement of the flow rate adjusting hole, the size of the flow rate adjusting hole changes from fully closed to fully open. The flow path of the fluid is indicated by an arrow.

The rotary casing 36 to which the discharge port 8 is attached has a retaining ring 35 fitted in a circumferential groove 34 formed at the tip of a pivot 32 fixedly provided in the front casing 31. Since it is integrated with the rotating casing 36, the rotating casing 36 is prevented from coming off with respect to the pivot shaft 32, and is rotatable about the pivot shaft 32. More specifically, a sliding contact fitting portion 48 in which an O-ring 47 is fitted is formed on the fitting side of the rotating casing 36 into the pre-installation casing 31, and a vertical wall 49 inside thereof has a sliding contact fitting part 48. A shaft hole 50 through which the pivot shaft 32 is rotatably inserted and a circulation hole 51 through which a fluid flows are perforated and formed, and from a cavity 52 formed outside the vertical wall 49 thereof in a direction orthogonal to the pivot shaft 32, An opening 37 for screwing and fixing the discharge port 8 is formed.
The discharge port 8 is provided with a retaining ring 35 that is screwed and fixed to the opening 37 of the rotating casing 36, and a lid 39 is screwed onto the tip of the retaining ring 35 so that the filtering member 40 and the like are attached. The rotating casing 36 is attached.
As shown in the drawing, when the retaining ring 35 is screwed into the opening 37 in a state where the retaining ring 35 is fitted in the leading casing 31, the peripheral end of the retaining ring 35 is attached to the pivot shaft 32 on the leading casing 31 side. The rotary casing 36 is fitted in the circumferential groove 34, and is rotatably assembled to the pre-attached casing 31 in a retaining state. That is, unlike the conventional case, it is not necessary to provide a blind lid for assembling the rotary casing with respect to the front-mounted casing, the number of parts is reduced, and the rotary casing 36 having the discharge port 8 is very easily provided. I am able to assemble it.

On the other hand, the base portion 2 of the stopper water stopper fitting 1 is
2 and 3, the base portion of the conduit 6 is provided with a bolt 18 on a mounting / fixing portion 28 screwed and fixed to the supply port body 17 via a slide liner 15 made of Teflon resin having a flange portion on the upper portion. , 18 is a flange of a tubular retainer rotation member 13 that is rotatably fitted in a retainer holding member 19 that is fastened and fixed by screws 18, and is screwed and fixed to the inner periphery of the base end portion 11 of the conduit 6. The part 12 is slidably engaged with the lower end of the retaining presser member 19. The ring-shaped sliding packing 2 made of Teflon resin is provided in the groove portion formed on the peripheral surface of the collar-shaped portion 12 corresponding to the retaining member 19.
1 is fitted, and the sliding contact rotation operation of the collar-shaped portion 12 biased by the spring 27, which will be described later, toward the retaining pressing member 19 is made favorable, and the conduit 6 is kept in the retaining state to smoothly rotate. I am able to do that. The retaining member 19 is covered with a resin cover body 30 that is screwed and fixed to its upper peripheral portion.

The seal member 2 is provided on the lower surface of the collar portion 12 of the retaining rotation member 13 fixed to the base end portion 11 of the conduit 6.
6, a disk surface 14 is formed in sliding contact with the inner peripheral surface 10 of the mounting / fixing portion 28, which serves as a passage communicating with the supply port 5. One end of a cylindrical seal member 26 made of an elastic body such as a rubber body having a spring 25 is urged by a spring 27 so as to be slidably rotatable and watertight. Then, the disk surface 14 is made smooth by applying Teflon coating T or the like, and the seal member 2
It is preferable to prevent the seal member 26 from adhering to the disk surface 14 by reducing the slip resistance against the disk 6. By doing so, the sliding contact rotation operation of the disk surface 14 with respect to the seal member 26 is smoothed. In addition, the sealability between the disk surface 14 and the seal member 26 can be improved. Here, since the seal member 26 is constantly urged against the disc surface 14 by the spring 27, even if one end side of the seal member 26 is worn by the rotation of the disc surface 14, the seal member 26 is moved toward the disc surface 14. The urging state of does not change, and the sealing property between the two is always maintained stable.

Due to the smooth rotation of the disk surface 14 as described above, the circumferential convex portion 25 of the seal member 26 is always kept stationary and closely fitted to the inner wall 10 of the mounting and fixing portion 28. Therefore, the sealability between the inner wall 10 and the seal member 26 is kept good. Therefore, unlike the conventional case, the problem that the sealability is deteriorated due to the wear caused by the rotation of the O-ring together with the conduit is eliminated.

In order to prevent the trouble of inadvertently discharging the fluid out of the sink 3 by restricting the range of rotation of the discharge port 8, as shown in FIG. The pair of protrusions 54, 54 are fitted into the support portion 53 of the pivot 32 of the rotating shaft casing 31.
On the corresponding vertical wall 49, a swingable protrusion 55 may be formed between the two protrusions 54, 54. By doing so, the rotation of the rotation casing 36 is allowed within the range in which the protrusion 55 of the rotation casing 36 can move (see FIG. 6), and further rotation can be restricted.

In order to be able to set the turning position of the conduit 6, in particular, a vertical hole is formed in the receiving surface of the mounting and fixing portion 28 corresponding to the peripheral surface of the collar-shaped portion 12 of the retaining rotation member 13. (Not shown) is formed by drilling, and a ball 24 biased by a spring 23 (see FIG. 7) is fitted into the vertical hole, and the ball 24 is prevented from coming off and the lower peripheral surface of the collar-shaped portion 12 of the turning member 13 is prevented. It suffices that the plurality of receiving holes 16 formed in the above are made to correspond. By doing so, either of the receiving holes 1
By engaging a part of the ball 24 with the ball 6, the conduit 6 can be stably locked at that position, and the discharging direction of the fluid can be stably maintained during discharging.
