Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting elbow for running water pipes, which is cut so as to correspond to the inner diameter of hoses of various water pipes and the like, so that the hoses are securely connected.

[0002]

2. Description of the Related Art Conventionally, in connection elbows of this type, it has been found that two hose sections having different diameters, a small-diameter pipe section and a large-diameter pipe section, are formed in one hose connection section.

[0003]

Conventionally, in a connecting elbow for a water pipe of this kind, when the inner diameter of the hose is minimum, the connection can be directly fitted, but when connecting a hose having a large inner diameter, the elbow is connected. The small-diameter pipe part of the hose connection part is inserted and hidden inside the hose, and the appearance is not particularly bad, but the small-diameter pipe part becomes a resistance at the time of distribution and causes a problem that it becomes a brake on the passage of running water It is. The present invention has been made in view of the above-mentioned problems of the prior art, and its main purpose is to easily connect hoses to three types of hoses having different inner diameters such as water pipes. Make it available for use. In the case of a hose other than the hose connected to the first small-diameter pipe part of the hose connection part, the hose connection is cut sequentially to match the inner diameter of the hose and firmly connected. An elbow is provided.

[0004]

In order to achieve the above object, the present invention provides a hose connecting part (2) and a connecting part (3) which becomes a union joint at right angles to the hose connecting part (2) with a synthetic resin at right angles. is there. In the hose connection part (2), three types of a small diameter pipe part (5), a medium diameter pipe part (6) and a large diameter pipe part (7) are integrally formed from the tip. A cutting section (8) and a cutting section (9) for cutting are provided near the base of the small-diameter pipe section (5) and the medium-diameter pipe section (6). In addition, inclined projection rings (10) (10) are formed on the outer periphery of the small-diameter tube portion (5), the medium-diameter tube portion (6), and the large-diameter tube portion (7) so as to protrude toward the base direction. It is.

[0005]

The present invention is constructed as described above. The use of this connecting elbow will be described. First, FIG. 3 shows that the hose connecting portion (2) of the elbow main body (1) has the most advanced small-diameter pipe. The small-diameter hose (13) corresponding to the part (5) is fitted as it is. At this time, the L-shaped connecting portion (3) is inserted into a ready-made union. Next, in the state shown in FIG. 4, when the inner diameter of the medium-diameter hose (14) of the hose connection part (2) matches the medium-diameter pipe part (6), the small-diameter pipe part (5) is used. It is used after being cut by the cutting portion (8) at the base. FIG. 5 shows a large-diameter hose (1) that matches the large-diameter pipe (7) of the hose connection (2).
5) When inserting the large-diameter hose (15), it is cut at the cutting portion (9) at the base of the medium-diameter tube (6).
To be firmly attached.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings, an embodiment of the present invention will be described. FIG. 1 shows a slope of an elbow main body (1) of the present invention. The elbow main body (1) is formed of a synthetic resin.
A hose connecting part (2) for connecting various hoses and a connecting part (3) for connecting to a union joint or the like at a right angle from the hose connecting part (2) are provided to form an L-shape. The hose connection (2) has a small-diameter pipe (5) and a small-diameter pipe (5) from the tip.
A large-diameter tube portion (6) is formed adjacent to the large-diameter tube portion (6), and a large-diameter tube portion (7) is formed sequentially adjacent to the medium-diameter tube portion (6). At the base of the small-diameter pipe part (5) and the medium-diameter pipe part (6), a cutting part (8) and a cutting part (9) for cutting, respectively.
have. Also, inclined projection rings (10) (10) protruding toward the base direction on the three types of outer circumferences of the small-diameter tube portion (5), the medium-diameter tube portion (6), and the large-diameter tube portion (7). )
(10)... Are formed in several stages.

The outer diameter of the hose connecting portion (2) of the elbow body (1) is, for example, 13 for the small diameter pipe (5).
m / m, 17 m / m for the medium diameter pipe (6) and 22 m / m for the large diameter pipe (7). Further, the end of the connecting portion (3) of the elbow body (1) is inserted and fixed into an existing union, and has an outer peripheral dimension of 22 m / m. Reference numerals (11) and (12) indicate respective water inlets, (13) indicates a small-diameter hose fitted and connected to the small-diameter pipe (5), and (1)
4) is a medium-diameter hose fitted and connected to the long-diameter tube (6),
(15) shows a large-diameter hose fitted and connected to the large-diameter tube (7).

[0008]

As described above, according to the connecting elbow for running water pipes of the present invention, various water pipes having different inner diameters are used.
The effect that each type of hose can be easily inserted and connected, and it does not require several elbows corresponding to each inner diameter unlike the conventional elbow, and it can be fully supported with one elbow, and it is very convenient and economical Effect. Since it is made of synthetic resin, molding is easy, and since a cutting portion for cutting is provided at the base of the small-diameter tube and the medium-diameter tube, a hose is inserted into the medium-diameter tube. Sometimes the base of the small-diameter tube can be cut easily, and when connecting the hose to the large-diameter tube, simply cut the base of the medium-diameter tube to easily and reliably connect each hose with a different inner diameter. There is a convenient effect that can be connected. Furthermore, the small-diameter pipe section, the medium-diameter pipe section, and the large-diameter pipe section have
Since an inclined projection ring protruding toward the base direction is formed on each outer periphery of each type, there is an effect that each hose is securely connected without loosening.
