Reference numeral 7 denotes a branch stopper main body, which is composed of a connecting cylinder 8 with both ends open, and a supporting cylinder 9 that projects from the side surface of the connecting cylinder 8 and communicates with the inside of the connecting cylinder 8.

Reference numeral 10 denotes a connecting tube which is inserted into the connecting tube 8 so as to be slidable in the axial direction thereof, has a smaller diameter than the connecting tube 8, and has one end closed, and has a length such that its open end 10a side protrudes from the connecting tube 8. , and open end 1
A cylindrical gasket 11 attached to the valve seat 0a is brought into contact with the valve seat 5a to guide water supplied to the water supply connecting portion 2 to the connecting tube 10. 11
A is a cover for the gasket 11, which is made of metal or hard synthetic resin and is formed into a pipe shape, which prevents unnecessary deformation of the gasket 11 and ensures watertightness.

Reference numeral 12 is a communication hole provided on the closed end 10b side of the connecting cylinder 10, and 13 is a set screw as screw means for supporting the closed end 10b of the connecting cylinder 10, which is engaged with a thread on the inner periphery of the end of the connecting cylinder 8.

14a and 14b are the communication holes 12 of the connecting cylinder 10.
O-rings 15a, 15 are installed on the surfaces of these partition walls 14a, 14b facing the connecting cylinder 10, so as to separate the parts provided with the connecting cylinder 8.
b is provided to prevent water flowing out from the communication hole 12 of the connecting cylinder 10 from leaking out of the branching chamber 8a.

Reference numeral 16 denotes a through hole provided on the side of the support tube 9 in the branch chamber 8a, and a valve seat 16a is provided on the downstream side of the periphery thereof. Reference numeral 17 denotes a valve body that opens and closes the valve seat 16a, and 18 denotes a spindle that is screwed into the support tube 9 so that it can move forward and backward.The valve stem 17a of the valve body 17 is inserted into a support hole 18a at one end of the spindle. Reference numeral 19 denotes a pressing nut that is engaged with a thread on the outer periphery of the support cylinder 9, which presses a gasket (not shown) against the end of the support cylinder 9 to close the support cylinder 9. 20 is spindle 1
This is the handle attached to 8.

A connecting nut 21 is rotatably attached to the end of the connecting tube 8 as a connecting means, and is engaged with a thread on the outer periphery of the attaching tube 6 to connect the connecting tube 8 to the attaching tube 6. 22 is Patsukin.

As shown in FIG. 3, the connecting nut 21 has a plurality of recesses 23 provided on the outer peripheral surface of the connecting tube 8.
A metal ball 25 is fitted across a ring-shaped groove 24 on the inner peripheral surface of the connecting nut 21, and is rotatably attached to the connecting tube 8 in a non-separable manner. Reference numeral 26 designates an insertion hole provided in the connecting nut 21 so as to communicate with the concave groove 24, from which the ball 25 is inserted.
are inserted into the recess 23 and the groove 24. Reference numeral 27 denotes a closing ball inserted into the insertion hole 26 to prevent the ball 25 from deviating from the insertion hole 26. This ball is made to have approximately the same diameter as the insertion hole 26 to prevent it from deviating from the insertion hole 26.
Instead of the closing ball 25, it is also possible to attach a set screw to the insertion hole 26.

To fit the balls 25 into each of the recesses 23, insert the balls 25 into the insertion holes 26, and then insert the balls 25 into the connecting tubes 8.
Or sequentially by rotating the connecting nut 21.

In FIG. 2, 28a and 28b are the branch chamber 8a.
This is a branch connection portion that protrudes from the connection tube 8 and communicates with the connection tube 8.

In the above configuration, the connection of the branch faucet body 7 to the existing faucet body 1 excludes the valve body of the faucet body 1, the spindle for operating it, its handle (not shown), and the like. Then, the set screw 13 is rotated in a direction to loosen it, the connecting tube 10 is made movable toward the set screw 13, the connecting tube 10 is inserted into the mounting tube 6, and the connecting tube 8 is inserted through the packing 22. and connect it to the mounting tube 6 with a connecting nut 21 in a watertight manner. Therefore, when the connecting nut 21 is not sufficiently tightened and the mounting tube 6 and the connecting tube 8 are not watertight, the open end 10a of the connecting tube 10 comes into contact with the partition wall 4, causing the connecting nut 21 to tighten. The connecting nut 21 can be sufficiently tightened without becoming impossible to tighten, and the connecting tube 8 can always be connected to the mounting tube 6 in a watertight manner.

When the connection of the connecting tube 8 to the mounting tube 6 is completed, the set screw 13 is tightened to allow the open end 10a of the connecting tube 10 to communicate with the water passage hole 5 via the packing 11 and to contact the partition wall 4 in a watertight manner. In addition, appropriate piping is provided to the branch connections 28a and 28b.

Therefore, the water supplied to the water supply connection 2 is
The water is guided from the water hole 5 to the connecting cylinder 10 and reaches the branch chamber 8a, so when the valve body 17 is moved to open the water hole 16, the water is ejected from the water spouting part 3 through the support part 9 and the connecting cylinder 8. . On the other hand, the water in the branch chamber 8a is
It is also branched into 8a and 28b.

In addition, the valve body 17, spindle 18, handle 2
0 can also be used for the faucet body 1.

FIG. 4 shows another embodiment, in which a set screw 13 is not provided, and a screw provided on the outer periphery of the closed end 10b of the connecting tube 10 is engaged with a screw of the connecting tube 8.
Since the other configurations are the same as those of the embodiment shown in FIGS. 1 to 3, the same reference numerals are given and detailed explanations are omitted.

Therefore, in this embodiment, since the connecting tube 10 moves when rotated, the length of the connecting tube 8 protruding from the connecting tube 8 can be adapted to the length of the mounting tube 6.

FIG. 5 shows another embodiment of the connection means between the mounting tube 6 and the connecting tube 8. The end of the connecting tube 8 is inserted into the mounting tube 6, and the screw provided on the outer periphery of the connecting tube 8 is inserted into the mounting tube 6. The connecting tube 8 is connected to the attaching tube 6 by inserting the end of the connecting tube 8 into the attaching tube 6 by engaging with a screw provided on the inner surface. Then, the packing 22 is tightened with a tightening nut 29 provided on the connecting tube 8 to make the connecting portion between the mounting tube 6 and the connecting tube 8 watertight.

Note that the connection of the connecting tube to the mounting tube 6 is as follows.
As in the conventional example shown in the figure, any means can be used, such as attaching a locking ring to the connecting tube and connecting the connecting tube 8 to the mounting tube 6 using a connecting nut locked thereto.

[Effect of idea]

As described above, the branch faucet of the present invention has a connecting tube inserted through the connecting tube connected to the mounting tube of the faucet body, and a screw means that allows the connecting tube to move forward and backward. Therefore, the length of the connecting cylinder protruding from the connecting cylinder can be arbitrarily changed by operating the screw means. Therefore, by operating the screw means according to the length of the attachment tube of the faucet body, the connection tube can always be connected to the attachment tube in a watertight manner regardless of the length of the attachment tube. With,
It is possible to make the open end of the connecting cylinder watertightly communicate with the water passage hole provided in the partition wall of the faucet main body.
