Are formed. The positioning concave portion 66a of the guide slot 66 is formed at two positions, that is, a position close to the flow rate adjusting lever 7 and a position distant therefrom. Thereby, the push lock means 6 is moved to the lock position where the engagement portion 65a of the push lock means 65 is engaged with the back surface of the disk portion 7a of the flow rate adjusting lever 7.
5 and a state in which the pushing lock means 65 is retracted to an unlock position where the engaging portion 65a of the pushing lock means 65 is completely retracted from the back surface of the disk portion 7a of the flow rate adjusting lever 7. In the above, the positioning projection 65c of the pushing lock means 65 is aligned with the positioning recess 66 of the guide elongated hole 66.
a, the push lock means 65 can be stably positioned between the lock position and the unlock position.

FIG. 4 shows a state in which the flow rate adjusting lever 7 is pushed. In this state, the upper end of the swing lever 48 is pushed by the flow rate adjusting lever 7, and the lower end of the swing lever 48 is floated to the front side. In this state, when the water supply hose side joint 15 is connected to the faucet side joint 16 as described above, the lower end of the swing lever 7 is pushed by the cylinder cover 41 of the water supply hose side joint 15. The upper end of the swing lever 48 rises to the front side against the urging force of a spring (not shown) that draws the rotation shaft 54 of the flow rate adjustment lever 7 into the inner side of the shaft support cylinder 55, Flow adjustment lever 7
Is pushed out to the front. Thereby, the flow control lever 7
As shown in FIG. 3, the protrusion 58 for adjusting the pushing amount is released from the notch 60 of the shaft support cylinder 55. That is, it becomes possible to operate the faucet 3 by opening the flow control lever 7 to the opening side.

As described above, when the flow control lever 7 at the stopper position is turned, for example, in the counterclockwise opening direction, the movable disk 21 slides on the fixed disk 20 via the transmission mechanism 8 and the stopper rod 22. It rotates on the moving surface T. In this case, as the movable disk 21 rotates, the notch 34 provided on the back surface of the movable disk 21 and the valve hole 33 of the fixed disk 20
And the amount of water supplied to the water purifier 12 increases. On the other hand, when the flow control lever 7 is turned clockwise, the water supply flow rate decreases and the movable disk 21 is closed when the back surface of the movable disk 21 closes the valve hole 33 of the fixed disk 20.

As described above, since the faucet 3 with the flow rate adjusting function can be used independently, the problems of the conventional example shown in FIG. 9 are obtained, that is, the switching cock 93 and the faucet itself such as the branch faucet. Since the branching mechanism needs to be provided, the usability is poor, and when the faucet 91 is a hot-water mixing faucet, if the switching state to the water supply is poor, the water may be supplied to the water purifier 94 in a state where the hot water is mixed. Problems can be solved at once.

When the water supply hose-side joint 15 is connected to the faucet-side joint 16, the flow rate adjusting lever 7
After turning to the closed position, as shown in FIG. 4, when the flow rate adjusting lever 7 is pushed into the back of the wall, the lower end of the swing lever 48 rises to the front side, and water is supplied at the lower end. The tube cover 41 of the joint 15 on the hose side is pushed back in the direction away from the faucet 3 (F direction). Thereby, the gripping force of the small ball 43 of the joint 15 on the water supply hose side is released, the joint 15 on the water supply hose side is detached from the joint 16 on the faucet side, the connection is released, and the valve by the push rod 44 is released. The pressing of the body 38 is also released. That is, the fitting 16 on the faucet side
The connection of the joint 15 on the water supply hose side can be easily performed by a one-touch operation of pushing the flow control lever 7.

Further, the pushing operation of the flow control lever 7 is performed when the flow control lever 7 is in the open position as shown in FIG.
As shown in (1), it is regulated by the projecting piece guide flange 59 of the shaft support cylinder 55, which is a push-movement regulating member. There is no possibility that the connection will be released from the fitting 16 on the faucet side. For this reason, the connection 15 on the water supply hose side is disconnected from the connection 16 on the faucet side in the open state, and the water outlet 14 of the faucet 3 is shortly before the check valve is operated. It is possible to eliminate occurrence of a situation such as overflow of water.

When the flow control lever 7 is in the open position, the cylinder cover 41 of the joint 15 on the water supply hose side is connected to the faucet 3.
Even if the joint 15 is disconnected from the faucet-side joint 16 by directly pulling it back in the direction away from the direction (F direction) by hand, the check valve of the faucet-side joint 16 works to close the water outlet 14. Therefore, a large amount of water is not discharged from the water outlet 14.

When the water supply hose side joint 15 is connected to the faucet side joint 16 and the flow rate adjusting lever 7 is turned to the closed position, as shown in FIG. If the engagement portion 65a is slid to a lock position where the engagement portion 65a is engaged with the back surface of the disk portion 7a of the flow adjustment lever 7, the flow adjustment lever 7 is inadvertently pushed by a mischief of an infant or the like, The water supply hose 13 can be reliably prevented from coming off the faucet 3.

In the above-described embodiment, the pushing lock means 65 is of a slide type, but may be of a rotary type as shown in FIG. That is, in the push lock means 65 of FIG. 8, by turning the operation portion 65b clockwise, for example,
The engaging portion 65a is disengaged from the back surface of the disk portion 7a of the flow rate adjusting lever 7, and the operating portion 65b is turned counterclockwise to engage the engaging portion 65a with the back surface of the disk portion 7a of the flow rate adjusting lever 7. At the same time, the pushing of the flow rate adjusting lever 7 at the closing position is prevented.

In the above-described embodiment, the case where the faucet 3 with the flow rate adjusting function is a single faucet has been described. However, the present invention can be similarly applied to a hot and cold mixed faucet.

[0029]

As described above, according to the present invention, since the faucet with the flow rate adjusting function can be used alone, the conventional problem, that is, it is necessary to provide a branching mechanism from the faucet itself. , A long water supply hose is required, which obstructs the cleaning of the sink, makes it impossible to use the water faucet for maintenance, etc. it can.

Further, since the faucet with the flow rate adjusting function is provided with the disconnection mechanism, the connection of the water supply hose side joint from the faucet side joint can be easily performed by one-touch operation of pushing the flow rate adjusting lever. .

Also, since the push-locking means is provided on the faucet with the flow rate adjusting function, when the flow rate adjusting operation member is at the closing position, the push-locking means is set to the locked state, so that the mischief of an infant or the like can be prevented. As a result, it is possible to reliably prevent the flow rate adjusting operation member from being pushed and the disconnection mechanism to operate, and the water supply hose from coming off the faucet.

Further, since the water tap having the flow rate adjusting function is provided with the push-moving restricting member, the connection releasing mechanism is operated in the open state to disconnect the water supply hose side joint from the water tap side joint. There is no danger.
