The insertion portion 32 is formed in a cylindrical shape extending downward from the fixing portion 31 and has a passage 32c connected to the water supply hose 110 therein.

A fixing groove 32a is formed in the outer circumferential surface of the insertion portion 32. The fixing groove 32a is inserted into the insertion hole 121 of the connection socket 120. The fixing groove 32a ) Is provided with a tight contact member (34) fitted therein. The fastening member 34 is made of a flexible material such as soft silicone and is inserted into the fixing groove 32a of the insertion portion 32 so as to be elastically brought into close contact with the fixing hole 122 of the connection socket 120 Respectively.

A packing groove 32b is formed at a lower portion from the fixing groove 32a of the insertion portion 32 by a predetermined distance. A packing 33 is provided in the packing groove 32b so as to be in close contact with a protrusion 123 formed on the inner circumferential surface of the insertion hole 121 of the connection socket 120 to maintain watertightness between the connection socket 120 and the coupling 30, Respectively.

6A, the length of the packing groove 32b formed in the insertion part 32 is extended in the axial direction of the insertion part 32, that is, in the insertion direction of the insertion part 32, A plurality of packings 33, for example, three packings 33 are inserted into the packing grooves 32b having the extended width.

The bottom surface or the inner circumferential surface of the packing groove 32b of the insertion portion 32 is inclined so that the diameter gradually decreases toward the insertion direction of the insertion portion 32. [

5, the female coupling portion 31a of the coupling 30 is screwed to the male screw portion 131 of the faucet 130, The operation of fixing and separating the coupling 30 from the faucet 130 is very convenient.

6A, by fitting the insertion hole 121 of the connection socket 120 into the insertion portion 32 of the coupling 30 fixed to the faucet 130, The coupling socket 120 is inserted into the fixing groove 32a of the coupling 30 to fix the coupling socket 120 and the coupling 30 and the coupling portion 30 of the coupling 30 The packing 33 of the gasket 33 can be closely adhered to maintain the watertightness.

Since the plurality of packing 33 are fitted in the packing groove 32b formed in the insertion portion 32 of the coupling 30 according to the present invention, even if the connection socket 120 of the water supply hose 110 is changed, Reliable fixing and watertight functions can be reliably performed regardless of the company.

That is, the distance a from the fastener 122 to the protrusion 123 is slightly different depending on the manufacturer of the connection socket 120. 6B, when the distance a1 from the fixture 122 to the protrusion 123 is short, the uppermost packing 33 out of the three packings 33 is pressed against the protrusion 123 And the water pressure acting on the inside pressurizes the packing 33 toward the protrusion 123 so that the packing 33 located at the uppermost position is in close contact with the protrusion 123 to maintain watertightness.

When the distance a2 from the fixture 122 to the protrusion 123 is long as shown in FIG. 6C, the packing 33 positioned in the middle among the three packings 33 is close to the protrusion 123 And the water pressure acting inside thereof presses the packing 33 toward the protruding portion 123, so that watertightness can be reliably maintained.

6D, when the inner diameter b1 of the protrusion 123 is large, the bottom of the packing groove 32b is inclined so that the diameter becomes smaller in the insertion direction of the insertion portion 32. Therefore, When the packing 33 is pressed by the water pressure acting inside it, the diameter of the packing 33 is increased by the movement of the diameter of the packing 33 in the groove 32b so as to expand the packing 33 Is brought into close contact with the protrusion 123, watertightness can be reliably maintained.

As described above, the coupling 30 of the present invention has compatibility with which the connection socket 120 can perform the fixing and watertight functions even if the sizes of the connection sockets 120 are different according to the manufacturers.

5, the coupling 30 of the present invention has the fastening member 34 fitted to the fastening groove 32a of the insertion portion 32. Therefore, The coupling socket 120 and the coupling 30 can be more firmly fixed to each other by being elastically brought into close contact with the contact member 34 when the insertion hole 122 is inserted into the fixing groove 32a, Even when the clearance between the insertion hole 121 of the connection socket 120 and the insertion portion 32 of the coupling 30 is changed as shown in FIG. So that a firm fixation can be maintained.
