接続ナツト４に螺合する取付ネジ６を内方に螺入
させることにより、取付ネジ６を蛇口５外面に圧
着させて取付けていた。ところが、この場合には
蛇口５と接続パツキン３との圧着力が十分でなか
つたり蛇口５と接続パツキン３とが傾いた状態で
圧着したりして、シール性が悪く、水があふれ出
るという問題があつた。(b) Conventional technology and its problems Conventionally, in order to directly connect a switching valve to a faucet, the first
As shown in the figure, a connecting nut 4 that protects the connecting gasket 3 is screwed into the upper opening 2 of the valve body 1,
With this connecting nut 4 fitted onto the faucet 5 and the tip of the faucet 5 crimped onto the connecting gasket 3,
By screwing inward the mounting screw 6 that is screwed into the connecting nut 4, the mounting screw 6 is crimped and attached to the outer surface of the faucet 5. However, in this case, there is a problem that the crimping force between the faucet 5 and the connecting gasket 3 is not sufficient, or the faucet 5 and the connecting gasket 3 are crimped at an angle, resulting in poor sealing and water overflowing. It was hot.
そこで、第２図のようにバルブ本体１に接続パ
ツキン３と接続ナツト４とを保持するグランドナ
ツト７を螺合させ、取付ネジ６を螺入して蛇口５

めつけることにより、蛇口５と接続パツキン３と
の圧着力を増大させ、かつ傾きを修正し、水漏れ
を防止するようにしたものも提案されている。 Therefore, as shown in Fig. 2, the gland nut 7 that holds the connecting gasket 3 and the connecting nut 4 is screwed onto the valve body 1, and the mounting screw 6 is screwed into the faucet 5.
It has also been proposed that by tightening the gland nut 7 while the faucet 5 is crimped on the outer surface, the crimping force between the faucet 5 and the connecting gasket 3 is increased, and the inclination is corrected to prevent water leakage. .
しかしながら、上記いずれの場合も、取付ネジ

欠点がある。また、後者の場合には取付ネジ６が
蛇口５に食い込んでいると、グランドナツト７を
締め付けても、蛇口５と接続パツキン３との傾き
を修正することができず十分な水漏れ防止効果が
期待できない欠点があつた。 However, in any of the above cases, when the mounting screw 6 is crimped onto the faucet 5, scratches and dents are formed on the outer surface of the faucet 5, which impairs the appearance and tends to cause rust. In the latter case, if the mounting screw 6 is biting into the faucet 5, even if the gland nut 7 is tightened, the inclination between the faucet 5 and the connecting gasket 3 cannot be corrected, and the water leak prevention effect will not be sufficient. There were some unexpected flaws.
(ハ) 考案の目的

装置を提供することを目的とする。(c) Purpose of the invention The present invention was made to eliminate the latter drawback, and is capable of increasing the pressure bonding force between the faucet and the connecting gasket and correcting the inclination, without damaging the faucet's outer surface by tightening the mounting screws. It is an object of the present invention to provide a connection device for direct connection to a faucet that is easy to use.

Three mounting screws 16 are threaded into the connecting nut 14 in the radial direction, and a protective cap 17 made of synthetic resin (for example, polypropylene) is attached to the tip of each mounting screw 16. The protective cap 17 may be integrally molded on the tip of the mounting screw 16, fixed with adhesive, or simply fitted onto the tip of the mounting screw 16.
The protective cap 17 of the mounting screw 16 is pressed onto the outer surface of the water faucet 18, and the faucet 18 and the connection gasket 15 are kept in close contact with each other.

This valve lever 20 can switch the tap water flowing in from the faucet 18 to the raw water supply port 22 or the supply port 23 to the water purifier by rotating the knob 21 by 90 degrees in either the left or right direction. A rectifier 24 is fitted around the outer periphery of the raw water supply port 22, and the outer periphery of the rectifier 24 is covered with a rectifier cover 25 fitted to the lower end of the main body 11.

均一に圧着する。 A method for directly connecting the switching valve having the above configuration to the faucet 18 will be explained. First, fit the connection nut 14 onto the faucet 18, and screw the mounting screw 16 inward with the tip of the faucet 18 in close contact with the top surface of the connection gasket 15.
7 is crimped onto the outer surface of the faucet 18. When the gland nut 13 is tightened against the main body 11 from this state, the connecting nut 14 is drawn toward the main body 11, and the tip of the faucet 18 is strongly pressed against the connecting gasket 15. If the mounting screw 16 is crimped onto the outer surface of the faucet 18, the main body 11
8, the tip of the faucet 18 will not be evenly pressed against the connection gasket 15. In this case as well, by tightening the gland nut 13, the protective cap 17 of the mounting screw 16 crimped onto the outer surface of the faucet 18 slides slightly downward with respect to the faucet 18, and the protective cap 17 is formed at the tip of the faucet 18. It stops when it hits the raised protrusion 18a (see FIG. 6).
As a result, the inclination of the faucet 18 and the main body 11 is corrected, and the faucet 18 and the connecting gasket 15 are evenly pressed together over the entire surface.

ジ１６が蛇口１８から脱落することがない。 In addition, in the above embodiment, the protrusion 1 is provided at the tip of the faucet 18.
8a, the present invention can also be applied to a faucet that does not have such a protrusion 18a. However, if the protrusion 18a is provided, even if the gland nut 13 is tightened too much, the protective cap 1
7 is locked against the protrusion 18a, so the mounting screw 16 does not fall off from the faucet 18.
また、本考案は上述のごとき切換バルブに限ら
ず、蛇口と道水管とを連結する単なる連結装置と
して用いることができることは勿論である。 Moreover, the present invention is not limited to the above-mentioned switching valve, but can of course be used as a simple connecting device for connecting a faucet and a water pipe.

心配もない。(f) Effects of the invention As described above, according to the invention, a resin protective cap is attached to the tip of the mounting screw, so when the mounting screw is crimped onto the faucet, it does not cause scratches or dents on the faucet's outer surface. It is possible to prevent rust from occurring without damaging the appearance. Additionally, as the gland nut is tightened, the protective cap can slide on the faucet's outer surface, so even if the body and faucet are tilted when the mounting screws are crimped onto the faucet, this tilt can be corrected. This allows the faucet and the connecting gasket to be strongly and uniformly crimped. Therefore, it can be easily connected by anyone, and there is no fear of water leakage.
