[Prior Art] A water treatment device such as a water purifier or an electrolyzed water generating device is disclosed in Japanese Laid-Open Patent Publication No. 2000-231. The hydrant portion is arranged on the upper surface of the flow table. A faucet is provided in the flow table, and a water supply pipe is branched from the middle of the tap water pipe leading to the faucet. The water supply pipe is connected to the body. The water treated in the body is discharged through the hydrant portion. The water supply pipe is a water supply joint connected to the back side of the main body provided in the flow table, and the water supply joint is a water supply pipe and a water supply joint located on the back side of the main body in a narrow space provided in the flow table. It becomes extremely difficult to become an operation by hand. In order to facilitate the above-mentioned connection work, the connection portion formed by the flange of the water supply joint and the flange provided at the end of the water supply pipe is fitted, and the elastic holder is fitted (refer to Japanese Patent Laid-Open No. Hei 6) - 2 6 4 4 8 0), and the two flanges are embedded in the grooves of the holder, thereby completing the above connection. At this time, the clamp may be installed at an offset position to make the connection of the clamp an inaccurate state. If water pressure is applied to the joint, water leakage may occur or the connection may be loose and flowable. Flooding occurred in the station. -4-200905045 SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object thereof is to provide a water treatment apparatus which can be easily and surely carried out even if the connection with the water supply pipe is by hand. . The present invention for solving the above problems is a water treatment device that is installed in a flow table and connected to a water supply pipe, and is characterized in that a water supply joint is provided, and a plug portion of the water supply pipe is inserted into the water supply joint and is disposed in the water supply pipe. a sealing member on an outer circumference of the plug portion contacts an inner circumferential surface of the water supply joint; a cap nut rotatable about the shaft portion with respect to the plug portion is provided in the water supply pipe, and the water supply joint is provided with a screw for the cap nut to be screwed Male thread. The connection is joined by a cap nut and the plug portion is inserted into the water supply joint to form a shaft seal. At this time, a detachable clamp is attached to the connection portion between the water supply joint and the water supply pipe. A groove is formed in the holder, and a flange provided on the water supply joint and a flange of a cap nut provided in the water supply pipe are engageable in the groove. A foot piece is provided in the vicinity of the water supply joint, and the leg piece is provided with a recess for restricting the mounting position of the holder. By this, the clamp can be installed in the correct position and the connection between the water supply joint and the water supply pipe can be made more precise. According to the present invention, since the connection between the water supply pipe and the water supply joint is performed by the cap nut, the connection can be surely performed, and the plug portion is inserted into the water supply joint for shaft sealing 'so that even if the cap nut tip is loose There will still be no water leakage. Moreover, the connection can be made more sure by using the holder. Moreover, the clamp is limited to the recess and can only be installed in the correct position, so the clamp -5-200905045 will not be installed in the wrong part, and the actual connection formed by the clamp can be continuously obtained. [Embodiment] Hereinafter, the present invention will be described based on embodiments shown in the drawings. 2 is an example of a water treatment device according to the present invention, and the water treatment device (electrolyzed water generating device) illustrated in the drawing includes a body portion provided with a filtered water purification unit and an electrolytic cell and disposed in the flow table 9. 1. A water plug portion 2 provided on the upper surface of the flow table 9. The main body portion 1 and the water plug portion 2 are connected via two connecting pipes 2 1 and 22, and are connected via the signal line 23 (for connecting the operation portion 20 provided to the water plug portion 2 and the main body portion 1). Circuit) to connect. The water head 8 is disposed in the flow table 9, and the water supply pipe 3 is branched in the middle of the tap water pipe leading to the faucet 8. The water supply pipe 3 is connected to the body portion 1. The water supply pipe 3 is a water supply joint 4 connected to the back surface of the main body portion 1 to guide the tap water to the main body portion 1. The structure of the connection portion between the water supply joint 4 and the water supply pipe 3 is as shown in Fig. 1. The water supply joint 4 disposed on the back surface of the main body portion 1 has a flange 40 at the front end portion, and a male screw 41 is provided on the outer peripheral surface of the front end side of the flange 40. At the end of the water supply pipe 3 connected to the water supply joint 4, a plug portion 31 that can be inserted into the water supply joint 4, a cap nut that is located outside the plug portion 31 and that is rotatable relative to the plug portion 31 is provided. 3 0. A female screw 32 is formed on the inner circumferential surface of the cap nut 30, and a flange 34 is formed on the outer periphery of the front end of the cap nut 30. In the figure, reference numeral 3 5 denotes a detachment preventing portion 316 for preventing the cover nut 30 from being detached from the plug portion 31 on the outer peripheral surface of the plug portion 31, and the symbol 36 is represented by the outer peripheral surface of the plug portion 31. The 〇-shaped ring of the sealing member When the water supply pipe 3 is connected to the water supply joint 4, the plug portion 31 of the water supply pipe 3 is inserted into the water supply joint 4, and the cap nut 30 is rotated to make the cap nut 30 The thread 32 is screwed to the male thread 41 of the outer peripheral surface of the front end portion of the water supply joint 4. At this time, the plug portion 31 is inserted into the inside of the water supply joint 4, and the serpentine ring 36 of the outer peripheral surface is brought into contact with the inner peripheral surface of the water supply joint 4, thereby constituting the shaft seal. Therefore, even if the locking of the cap nut 40 is slightly loosened, water leakage does not occur. Further, since the rotation of the cap nut 30 is necessary, the water supply joint 4 is disposed on the side surface on the back surface of the main body portion 1, so that the above operation can be performed more easily. As shown in Figs. 3 and 4, a more secure connection can be achieved by using the holder 5. That is, the holder 5 having the front end opened and the groove 50 formed on the circumferential surface is sleeved on the outer circumference of the water supply joint 4 and the cap nut 30, and the flange 40 and the cap nut of the water supply joint 4 are allowed. The flange 34 of the front end 30 is embedded in the above-mentioned groove 50. As a result, the cap nut 3 can be prevented from coming loose. Further, in order to prevent the holder 5 from being attached to the offset position when the holder 5 is used, the wall surface (the upper surface of the leg piece 19 of the illustrated example) located below the above-mentioned connection portion of the body portion 1 is The distance η between the connecting portions is smaller than the opening width W of the front end portion of the holder 5 (W > 2H), and the concave portion 15 is provided at a position corresponding to the flanges 40, 34 of the wall surface, when the holder 5 is mounted When it is correct, the front end of one of the sides will be located in the recess 15. When the holders of the holders 200905045 5 are mounted at positions where the flanges 40, 34 are accurately fitted into the grooves 50, the holders 5 can be smoothly mounted by the recesses 丨5. However, when the holder 5 is mounted at another position, the front end edge of the holder 5 will hit the upper surface of the leg piece 19 and become unable to mount the holder 5, so that it can be mounted at an appropriate position. Set the clamp 5.
