Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a faucet joint.

[0002]

[Prior Art]

 Conventionally, a faucet and a male member at the tip of a one-touch joint are connected to a faucet joint by a tubular portion made of a hard resin material that is externally fitted to both, and a ring for press-fitting the external fitting end of the tubular portion to the male member from the outside. A structure is known in which the outer fitting end of the tubular portion to the faucet is tightly fixed with a vertical band as well as being crimped and fixed with a material.

[0003]

[Problems to be solved by the device]

However, in the prior art, the tubular part that connects the faucet and the male member at the end of the one-touch joint is molded with a hard resin material, and the elastic deformation due to rigidity is small and it is not possible to give flexibility to mounting. Not only is it not versatile because it can only be connected to a faucet with the specified diameter (size), but the tubular part itself does not have pressure resistance, so water leaks at home under conditions where the supply water pressure is 5 kgf / cm ² or more. There was a risk of being unable to use.

The present invention has been made in view of the above conventional circumstances, and its purpose is to provide a faucet joint having versatility for connecting to faucets having different diameters (sizes) and pressure resistance without water leakage. To provide.

[0005]

[Means for Solving the Problems]

 The technical measures taken to achieve the above-mentioned object are to connect the faucet and the male member of the one-touch joint by a tubular portion that fits over both of them, and vertically tighten the outer fitting end of the faucet of the tubular portion. In the faucet joint fastened to the faucet via the above, the tubular portion is connected to the faucet and the male member of the one-touch joint by a pressure-resistant rubber or soft resin connecting pipe body. The gist is that the spacer is made of a pressure-resistant rubber or soft resin spacer inner cylinder that is detachably fitted into the outer fitting end of the connecting pipe body to the faucet. Further, it is more effective if a C-shaped ring is mounted on the portion corresponding to the vertical tightening band in the spacer inner cylinder of the first aspect.

[0006]

[Action]

 The above technical means have the following effects. (Claim 1) When the spacer inner cylinder is removed from the connecting pipe body, the connecting pipe body constitutes a connecting portion for connecting to a faucet having a relatively large diameter (size), and conversely, the spacer inner cylinder body. The inner cylinder for the spacer constitutes the connection part when it is connected to the faucet with a relatively small diameter (size) when it is fitted inside the connection pipe. Since the inner tube for spacer and the connecting tube, which are made of rubber or soft resin and have pressure resistance, are freely deformed according to their diameter (size) by their own large elastic deformation, It has a large degree of freedom in attachment to various faucets (sizes), and is tightly fitted in a watertight manner and firmly connected to external faucets. (Claim 2) When the so-called caliber (so-called caliber) having a relatively small caliber (size) in which the connecting portion with the faucet is composed of the connecting pipe body and the spacer inner cylinder fitted in the connecting pipe body , The connecting part (connecting tube and spacer inner cylinder) becomes thicker, but the C-shaped ring shape retaining function does not cause distortion even if subjected to the tightening force of the vertical tightening band, and the inner cylinder for spacer Elastically deforms uniformly and comes into close contact with the outer peripheral surface of the faucet.

[0007]

[Effect of the device]

Since the present invention is configured as described above, it has the following advantages. (Claim 1) A connecting part for connecting to a faucet is formed by a connecting tube made of rubber or a soft resin and an inner cylinder for a spacer made of rubber or a soft resin which is detachably fitted in the connecting tube. Since it is configured, it is possible to provide the faucet having a relatively large diameter (size) and the faucet having a relatively small diameter (size) with water-tight connection by elastic deformation by themselves. Moreover, since the connecting tube and the spacer inner cylinder are made of pressure-resistant rubber or soft resin, water leaks even at home under conditions where the supply water pressure is 5 kgf / cm ² or more. It can be used without anxiety. In addition, since the inner cylinder for spacers can be simply attached and detached, the work when adapting to faucets with different diameters (sizes) is extremely easy. (Claim 2) When a spacer inner cylinder is fitted into the connecting pipe body to connect a faucet having a relatively small diameter (size), even if the portion tightened by the vertical tightening band becomes thicker, C Since the shape retaining function of the shape ring makes close contact with the outer peripheral surface of the faucet, the portion tightened with a so-called vertical tightening band that connects a faucet with a relatively large diameter (size) that uses only the connecting pipe is thin The watertightness similar to that in the case can be exhibited, and the fear of water leakage can be completely avoided.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. Embodiments of claims 1 and 2 are shown in FIGS. 1 to 4.

The faucet joint A is a pressure-resistant rubber or soft resin connecting tube 1 and a pressure-resistant rubber or soft that is removably fitted into the connecting tube 1. It is composed of a tubular portion A1 consisting of a resin spacer inner cylinder 2 and a vertical tightening band 3.

The connecting pipe 1 has a pipe inner diameter such that it can be externally fitted to the faucet 4 of a rectangular faucet or a large horizontal faucet, and the reinforcing bar is spirally oriented in an arbitrary direction such as a spiral. It is formed by cutting a rubber tube or a soft resin tube that is mounted and reinforced (provided with pressure resistance) with a length that allows connection between both the faucet 4 and the male member b at the tip of the one-touch joint B. There is.

An inner cylinder 2 for spacers is provided in the above-mentioned connecting pipe body 1 with a short cylindrical portion 2a having an outer diameter which can be internally fitted from an outer fitting end connected to the faucet 4 and a short cylindrical portion 2a. The connecting tube 1 is integrally formed with the flange portion 2b that comes into contact with the outer fitting end surface, and the inner diameter of the short tubular portion 2a is used as the faucet 4 of a home faucet or a small horizontal faucet. The outer peripheral surface is provided with a C-shaped ring 2c for shape retention on the outer peripheral surface at the center portion in the length direction. The spacer inner cylinder 2 is also made of a rubber tube or a soft resin tube, which is reinforced by lining the reinforcing bars in an arbitrary direction such as a spiral shape in the same manner as the connecting tube 1.

The vertical tightening band 3 has a well-known structure in which a metal-made thin plate-like object 3b mounted in an annular shape by changing the operation knob 3a to change the diameter of the wheel to change the fastening force. I will omit the explanation.

The male member b of the one-touch joint B is fitted with a nipple portion b2 at which one end of the flange portion b1 in the central portion is engaged with the connecting tube 1 and the other end of the male member b is fitted into the one-touch joint body B1. It has a structure in which it has a convex portion b3 for locking and a running water passage b4 is opened inside, and the above-mentioned connecting pipe body 1 which is externally fitted and locked in the nipple portion b2 is crimped by a ring material b5 press-fitted from the outside. It can be fixed.

Next, in the case of FIG. 1 and FIG. 2 in which the faucet 4 has a relatively large diameter (size), it is connected to the faucet in which the faucet 4 has a relatively small diameter (size). The case of FIGS. 3 and 4 will be described.

In FIGS. 1 and 2, after the lower end of the connecting pipe body 1 is externally engaged with the nipple portion 2b of the male member b, the ring member b5 is press-fitted from the outside to push the connecting pipe body 1 with one touch. Attach to fitting B. Up to this state, so-called producers, such as factories, do it. When connecting the connecting pipe 1 to the faucet 4, one end of the connecting pipe 1 is fitted onto the faucet 4 and the standing band 3 is fastened to a predetermined tightening force. As a result, both ends of the connecting pipe 1 are connected to the faucet 4 and the one-touch joint B in a watertight manner.

In FIGS. 3 and 4, in the same manner as in FIGS. 2 and 3, the spacer inner cylinder 2 is fitted in the upper half of the connecting tube 1 of FIGS. After the lower end of the connecting pipe body 1 is externally engaged with the nipple portion 2b of b, the ring material b5 is press-fitted from the outside to attach the connecting pipe body 1 to the one-touch joint B. When connecting the connecting tube 1 and the spacer inner cylinder 2 to the faucet 4, the spacer inner cylinder 2 is externally fitted to the faucet 4, and the tightening band 3 is tightened to a predetermined tightening force. As a result, both ends of the connecting pipe 1 are connected to the faucet 4 and the one-touch joint B in a watertight manner, and the spacer inner cylinder 2 is in close contact between the inner peripheral surface of the connecting pipe 1 and the outer peripheral surface of the faucet 4. Intervened in.

When the diameter of the faucet 4 shown in FIGS. 3 and 4 is relatively small, the elastic connection portion (the inner cylinder 2 for the spacer and the connection pipe body 1) C that is fastened by the vertical tightening band 3 has a large thickness. Although there is a risk of distortion and the like being generated in the elastic connection part C due to the flesh and tightening force, a C-shaped ring 2c for equalizing the tightening force is mounted on the outer peripheral surface of the spacer inner cylinder 2. Therefore, it is possible to maintain the same water-tightness as the elastic connecting portion C when the faucet 4 and the one-touch joint B are connected only by the connecting pipe 1.

The feature of this embodiment is that both the connecting tube 1 and the spacer inner cylinder 2 are formed of a pressure-resistant rubber material or a soft synthetic resin material, and both elastic deformation and pressure resistance are large. Therefore, if the diameter of the faucet 4 is relatively large or small, if the diameter of the faucet 4 is within the elastic deformation range, for example, even if the faucet 4 has a deformed special shape, it is possible to provide a certain degree of freedom in connecting in a watertight manner. Is.

In the faucet joint A of this embodiment, when the standing tightening band 3 is loosened and the connection with the faucet 4 is released, water is directly supplied from the water flow passage b4 of the male member b of the one-touch joint B.
