Description

[Detailed explanation of the invention] This invention usually involves attaching a chuck body to a water faucet, inserting the plug with a single touch as needed, and fixing it to supply water to the desired location. This relates to branch faucets.

Various types of branch faucets of this type have already been developed by this inventor, but when the diameters of water taps are different, the flow holes of the branch faucet to be connected may not match properly.

This problem is still good when the faucet is pressed and fixed with tightening screws from three directions of the chuck body, but it becomes noticeable when the faucet is pressed and fixed with tightening screws from one direction.

Furthermore, when the nipple is screwed into the chuck body in order to press the backing into close contact with the end face of the water faucet, it becomes more difficult to secure the effective area of the flow hole due to deviation of the backing in the radial direction.

This design is adaptable to water faucets of various diameters even if the fastener is tightened only from one side, and the backing does not shift in the radial direction depending on the nipple threading, reducing the required flow area. The purpose is to provide an excellent branch faucet that can be placed in a secure manner.

This invention will be explained in detail below based on the illustrated embodiments.

In the figure, reference numeral 1 denotes a branching plug, the outer periphery of which has a circular cross section, a groove 2 formed on the outer periphery of the tip, into which an O-ring 3 is fitted, and a cylindrical fitting portion including this tip. 4 is formed with a fitting groove 5 for the ball receiver.

Furthermore, the plug 1 has a tapered portion 6 at its end, and by fitting the collar 7 therein, one end of the joint hose 8 is held between the tapered portion 6 and the collar 7. ing.

The nipple 9 into which the plug 1 is removably fitted has a flange part 10 in the center, and a spring groove 11 on the lower side thereof.
In addition, the ball receiver has a support hole 13 that supports the ball 12 so that the ball 12 can be fit into the fitting groove.

A shifter 14 whose movement is regulated only in the axial direction by the spline groove 11 is slidably fitted into the nipple 9.

The shifter 14 has a tapered surface 15 at its lower end that presses the ball 12 inward into the support hole 13.

The chuck body 16 to which the shifter 14 is screwed is provided with a backing 19 having a non-circular cross section and having a through hole 18 communicating with the through hole 17 formed in the nipple 9.

The backing 19 is made of rubber, and if necessary has a key portion 20 formed on one side of the eccentric side, which is fitted into a key groove 21 formed inside the chuck body 16.

The chuck body 16 is equipped with, for example, a screw type adjustment fastener 22 that projects into the chuck body 16 from a direction in which the center of the chuck body is eccentric with respect to the center of the nipple 9.

In particular, this embodiment is equipped with screw-type fasteners 23.23 for swinging left and right by approximately 20 degrees from opposite directions.

The fasteners 23, 23 are adjusted in advance using a screwdriver or the like, and only the fastener 22 is screwed during normal attachment and detachment.

In this embodiment, a fastener 22.
An annular body 24 made of a suitable material is inserted corresponding to the position of 23.

In such a configuration, the chuck body 16 can be fixed to the faucet A by simply screwing only the fastener 22 while the faucet A is inserted into the chuck body 16. On the other hand, by screwing the nipple 9 and pushing up the backing 19 so as to bring it into close contact with the end face of the faucet A, the installation of the chuck body 16 is completed.

In this case, since the through hole 18 of the backing 19 is made to correspond to the faucet with the smallest diameter, its effective area will not be substantially narrowed even if the diameter becomes large.

Moreover, the center of rotation of the end face of the nipple 9 and the backing 19
Since the center of the backing 19 is offset from the center of the backing 19, even if the backing 19 is strongly tightened, there is no risk that the backing 19 will be rotated by the turning force (this embodiment is equipped with a key, so there is double protection in this respect). Although it has an effect).

Then, the shifter 14 is lifted up and placed so that the tapered surface 15 faces the support hole 13, and from the lower end of the nipple 9,
When the plug 1 is inserted, the ball 12 is pushed by the outer periphery of the plug 1 and slightly protrudes from the support hole 13 toward the tapered surface 15. However, when the plug 1 is completely inserted, the fitting groove 5 supports the ball 12. By lowering the shifter 14 facing the hole 13, the tapered surface presses the ball 12, introducing it into the fitting groove 5 and locking it.

This allows you to branch with one touch. Such a configuration provides the following effects.

(1) Plug can be connected with one touch by raising and lowering the shifter.

(2) By screwing the nipple into the chuck body, the backing can be brought into liquid-tight contact with the end face of the faucet;
Moreover, since the center of rotation during this tightening is different from the center of the backing inside the chuck body, the backing is not turned and the alignment between the backing passage hole and the communication hole is maintained.

(3) One-sided push using one adjustment fastener is used to fix the faucet to the chuck body, but since one-sided push is performed in the eccentric direction between the center of the chuck body and the center of the nipple, the size of the faucet There is no risk that the distribution area will be narrowed due to the difference in .
