Description

[Detailed description of the invention] (Field of industrial application) This invention is an eccentric branch pipe that is attached to an eccentric pipe for installing a hot water mixer faucet in order to branch to a dishwasher, water purifier, etc. Specifically, a nut member is rotatably fitted onto the mounting cylinder part of the branch pipe which is rotatable with respect to the branch pipe part of the eccentric pipe, and a retaining ring of the nut member is externally fitted onto the mounting cylinder part. The present invention relates to an eccentric branch pipe in which the attachment cylinder part of the branch pipe is relatively rotatably attached to the branch cylinder part of the eccentric pipe by fitting and screwing the nut member into the branch cylinder part.

(Prior Art) The conventional technology of such an eccentric branch pipe will be explained based on FIG. is fitted inside so that it can rotate freely. Reference numeral 10 denotes a nut member, on the inner periphery of which is a female thread 9 of the branching cylindrical portion 3a.
A male screw 8 is provided to be screwed into the mounting cylinder 5a, and the nut member 10 is fitted onto the mounting cylinder 5a so as to be relatively rotatable. Reference numeral 13 denotes a retaining ring, which is fitted into the groove 11 of the cylindrical mounting portion 5a so as to come into contact with the small diameter portion 10a of the nut member 10, and prevents the nut member 10 from rotating only relative to the cylindrical mounting portion 5a. In addition to being freely configured, the mounting cylinder part 5a
An O-ring 14 for sealing was externally fitted into the groove 12.

Therefore, the mounting cylinder part 5 is attached to the branch cylinder part 3a.
a and tighten the nut member 10, the nut member 10 and the branching cylindrical portion 3a are integrated,
The mounting cylinder part 5a can be relatively rotatably attached to the branching cylinder part 3a, and when a hose of a dishwasher, water purifier, etc. is connected to this mounting cylinder part 5a via a water faucet, it is possible to wash dishes. The mounting tube portion 5a rotates in accordance with the installation position of the water purifier, water purifier, etc., thereby preventing the hose from twisting.

However, when the hoses are connected, the mounting tube 5a may rotate downward due to the weight of the faucet or hose, and the hose also hangs downward. It had the drawback of getting in the way of things.

In addition, when the water purifier is mounted on one side, the weight of the faucet and the water purifier causes the mounting tube 5a to rotate downward, making it difficult to rotate the faucet, and the water purifier Another drawback was that the direction of water discharge could not be maintained as specified.

(Problems to be Solved by the Invention) The present invention aims to eliminate such conventional drawbacks, and, if necessary, attaches the mounting cylinder part of the branch pipe to the branch cylinder part of the eccentric pipe. The present invention aims to provide a convenient eccentric branch pipe that can be mounted relatively rotatably or fixedly mounted at a desired angle.

(Means for solving the problem) In order to achieve this object, the eccentric branch pipe according to the present invention has a tapered surface formed on the outer periphery of the mounting cylinder part, and a tapered surface corresponding to this tapered surface. A surface is formed on the inner periphery of the branching cylindrical portion, so that relative rotation of the mounting cylindrical portion with respect to the branching cylindrical portion can be prevented by abutment of both the tapered surfaces by tightening the nut member. It is characterized by

(Function) Therefore, by setting the angle of the mounting cylinder with respect to the branching cylinder and then strongly tightening the nut member, the branch pipe can be connected to the eccentric pipe by the contact of both tapered surfaces. It can be fixed and installed at any desired angle. Moreover, if the tightening of the nut member is stopped before the two tapered surfaces come into contact with each other, the branch pipe can be attached to the eccentric pipe so as to be rotatable relative to the eccentric pipe as before.

(Effect) In this way, if it is more convenient for the branch pipe to rotate freely, considering the surrounding circumstances, the branch pipe can be rotatably attached to the eccentric pipe as before. For example, when it is desired to fix the branch pipe, such as when installing a water purifier, the branch pipe can be fixed and attached at a desired angle to the eccentric pipe.

(Embodiment) An embodiment of the present invention will be described based on the drawings. Fig. 2 shows a water purifier attached to an eccentric branch pipe, 1 is a hot water mixing faucet, 2 is an eccentric pipe for hot water,
3 is an eccentric pipe for water, and to this eccentric pipe 3, a branch pipe 5 with a faucet 4 is attached so as to be relatively rotatable or fixed, as will be described in detail later. A water purifier 7 is attached to the water purifier 7 via a hose 6.

FIG. 1 shows the mounting structure of the eccentric pipe 3 and the branch pipe 5. As in the conventional case, the branch pipe part 5a of the branch pipe 5 is attached to the branch pipe part 3a of the eccentric pipe 3 for relative rotation. It is freely fitted inside, and the branching cylinder part 3
A nut member 10 having a female thread 9 that is screwed into the male thread 8 of a is fitted onto the mounting cylinder part 5a so as to be relatively rotatable, and the grooves 11 and 12 of the mounting cylinder part 5a
A retaining ring 13 and a sealing O-ring 14 are fitted inside, and by abutting the retaining ring 13 against the small diameter portion 10a of the nut member 10, the retaining ring 13 is fitted in the direction of the axis P of the mounting cylinder 5a. Nut member 10 to
movement is blocked. A tapered surface 15 is formed on the outer periphery of the mounting cylindrical portion 5a, and a small diameter protrusion 3 is formed on the inner periphery of the branching cylindrical portion 3a.
b is formed, and a tapered surface 16 corresponding to the tapered surface 15 of the mounting cylinder portion 5a is formed on the outer circumferential surface of this small diameter protrusion 3b, and both tapered surfaces 15 are formed by strongly tightening the nut member 10. , 16 are in contact with each other. Further, a valve seat 5b is integrally formed in the mounting cylinder part 5a, and a faucet 4 consisting of a valve body 17, a valve stem 18, a handle 19, etc. that abuts and separates from the valve seat 5b is branched. It is incorporated into the pipe 5.

Therefore, when the angle of the mounting cylinder part 5a with respect to the branching cylinder part 3a is set and the nut member 10 is strongly tightened, the tapered surface 15 on the side of the mounting cylinder part 5a
contacts the tapered surface 16 on the side of the branching cylinder 3a, and the branch pipe 5 can be fixed and attached to the eccentric pipe 3 at a desired angle. In addition, both tapered surfaces 15,
If the tightening of the nut member 10 is stopped a little before the nut member 16 comes into contact with the branch pipe 5, the branch pipe 5 can be attached to the eccentric pipe 3 so as to be rotatable relative to the eccentric pipe 3.

FIG. 3 shows another embodiment of an eccentric branch pipe in which a faucet 4 is not incorporated, and the one shown in this figure has a small diameter cylindrical portion 10b connected to a nut member 10, and the outer circumference of this small diameter cylindrical portion 10b. A male thread 8' formed in the above is screwed into a female thread 9' formed on the inner surface of the branching cylinder part 3a of the eccentric tube 3, and a retaining ring 13 is attached to the mounting cylinder part 5a of the branching pipe 5, and A tapered surface 15 is formed on the end side of the mounting cylindrical portion 5a, and a tapered surface 16 corresponding to the tapered surface 15 is formed on the inner periphery of the branching cylindrical portion 3a, as shown in FIG. The same components are given the same reference numerals and their explanations will be omitted.
