[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet joint used for attaching a hose to a required faucet such as a water tap.

[0002]

2. Description of the Related Art Hitherto, as this type of faucet joint, the one shown in FIGS. 6 to 8 has been known, and this will be described with reference to FIG. That is, in the figure, reference numeral 1 denotes a short tubular faucet attachment member which can be fitted to a faucet A such as a faucet.
Is a required number of fastening bolts screwed substantially radially to the upper portion of the mounting member 1 via the screw holes 3, 4 is a male screw portion formed on the lower outer peripheral surface of the mounting member 1, 5 a is the inside of the mounting member 1 A required number of notches 6a are formed upward on the upper peripheral wall of the ring 5a so as to fit the respective fastening bolts 2 therein. I have. 7a is a short bottomed cylindrical joint body having an internal thread 8 formed on the inner peripheral surface thereof to be screwed into the male thread 4 of the mounting member 1, and 9 is a water inlet formed at the bottom of the joint body 7a. , 10 are joint bodies 7a for communicating with the water inlet 9.
A small-diameter cylindrical hose mounting member integrally formed at the lower end of the
Reference numeral 11a denotes an annular packing receiver projecting upward from the inner surface of the bottom wall of the joint body 7a, and reference numeral 12 denotes a thick annular packing held on the packing receiver 11a.

In the conventional faucet joint constructed as described above, the mounting member 1 is externally fitted to the faucet A via the ring 5a, and each fixing bolt 2 is screwed inward to be mounted. Thereafter, the joint main body 7a is screwed tightly to the lower portion of the mounting member 1 via the female thread 8 and the male thread 4. Then, the packing 12 moves in the direction of the faucet A in synchronization with the screwing operation of the joint body 7a, and strongly presses against the distal end surface of the faucet A to maintain watertight. And the hose mounting member 1
A required hose (not shown), such as a washing machine hose, is attached to 0 and used.

[0004]

By the way, in the conventional faucet joint constructed as described above, when the tip of the faucet A is formed in a horizontal flat surface, the packing 12 is connected to the tip of the faucet A. The surface can be pressed against the surface with a uniform pressing force, so that the surface can be reliably kept watertight. However, when the tip of the faucet A has an uneven shape such as being inclined or distorted, as shown in FIG. 9, the packing 12 is pressed in contact with the distorted state according to the tip shape of the faucet A. As a result, the pressing force against the tip of the faucet A becomes non-uniform, so that not only is it difficult to reliably maintain watertightness, but also, in some cases, water leakage or the like may occur.

The faucet diameter adjusting ring 5a loosely fitted in the mounting member 1 has a required number of notches 6a formed in the upper peripheral wall thereof so that the fitting bolts 2 can be fitted from below. Because it is configured, when fitted to a faucet A with a slightly different diameter, the diameter adjusting function can be effectively exhibited, but when it is necessary to attach to a faucet A with a non-adjustable diameter. Is to remove the ring 5a by unscrewing the fastening bolt 2 or unscrewing the joint body 7a from the mounting member 1 and replace it with another ring, which is very troublesome. It was troublesome.

Further, when the joint body 7a is screwed to the mounting member 1, the packing 12 is properly tightened without excess and deficiency, and the mounting member 1 is screwed at the time of screwing in order to reliably maintain a watertight state. Upper end and joint body 7
It is necessary to set a predetermined distance L from the upper end of the line a (see FIG. 9). However, the conventional faucet coupling has no positioning mark, and as a result, excessive or insufficient tightening of the packing 12 tends to cause inconvenience.

The present invention solves the conventional problems at a glance, and even when the faucet tip has a non-uniform shape such as inclination or distortion, the packing is always pressed against with a uniform pressing force to maintain watertightness. It is an object of the present invention to provide a faucet joint that can surely perform the fitting.

Further, the present invention not only allows the faucet diameter adjusting ring to be easily replaced according to the faucet diameter, but also allows the fitting body to be properly screwed into the faucet mounting member. It is an object of the present invention to provide a faucet joint capable of performing the above-mentioned operations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 5b is a faucet diameter adjusting ring loosely fitted in the faucet mounting member 1, and 6b is loosely fitted in the mounting member 1 from above and fitted to the fastening bolt 2 on the lower peripheral wall of the ring 5b. Notch portions 13 formed downward are locking projections protruding from both sides in each notch portion 6b so as to be locked to the fastening bolt 2. When the joint body 7b described later is screwed into the mounting member 1, the ring 5b comes into contact with the upper end surface of the packing 12 and is set to a required height so as to appropriately detect the degree of screwing. I have. 7b is a joint body which can be screwed to the lower part of the mounting member 1; 14 is a substantially hemispherical pit formed on the periphery thereof so as to communicate with the water passage 9 in the joint body 7b;
Is a substantially hemispherical packing receiver floatingly held in the pit 14; 15 is a large-diameter water hole formed at the center of the packing receiver 11b so as to communicate with the water hole 9 through the pit 14;
Reference numeral 16 denotes an O-ring mounted on the outer periphery of the packing receiver 11b.

The other parts are the same as those of the conventional example, and the same reference numerals indicate the same parts.

When the embodiment constructed as described above is mounted on a faucet A having a slanted end surface as shown in FIG. 5, for example, the faucet A is first attached to the faucet A via a ring 5b. The mounting member 1 is externally fitted, and each fastening bolt 2 is screwed inward to mount. At this time, the ring 5b
Does not match the faucet A, the ring 5b is pulled out, the other ring is loosely fitted into the mounting member 1 from above, and the fastening bolt 2 is fitted and locked in the notch 6b. Thereafter, the attachment member 1 may be attached to the faucet A. When the mounting of the mounting member 1 is completed, the joint body 7b is screwed into the lower portion of the mounting member 1 via the male screw portion 4 and the female screw portion 8, and the packing 12 is supported by the packing receiver 11b.
