The present invention relates to a structure of a connection pipe for cold and hot water pipes, and more particularly, to form a spring-shaped coil tube having a coil-shaped tension force in a predetermined length and shape, and bushings at both ends of the spring-shaped coil tube. Insert the fitting, the bushing is characterized in that the fastening nut, O-ring, washer, clip ring to the circumferential portion of the inner end portion is configured by inserting sequentially.

As described above, the spring-type coil pipe is stretched without being bound to the interval or length to be piped during cold and hot water piping work by a connection pipe composed of a coil-shaped spring coil pipe having a tension force as described above. It can be used to reduce the pipe, it is to facilitate the fastening operation even in a narrow space without leakage when combined with the other coupling portion to be coupled to the coupling nut formed to the coupling nut formed at both ends of the spring-type coil pipe.

Generally, several types of hoses are used to transfer fluids.

Such a hose is connected to a fastening device for supplying or supplying a fluid. At this time, the end of the hose is connected to a separate fastener and fastened to the fastening device, and the fastener is formed with a screw to fasten with a packing. It was formed as a nut to tighten and fasten the fastening nut to the fastening device to be connected.

However, the conventional connection or fastening method as described above requires a tool such as a pipe wrench or spanner when connecting or disconnecting the fastening nut to the fastening device, which makes the connection and disconnection work complicated and cumbersome, and takes much time. There was a flaw.

In addition, when the space to be tightened is narrow, the working space for using the tools such as the pipe wrench or spanner is insufficient, and the fastening state between the fastening device portion and the fastening nut is incomplete and the fastening state becomes poor. There was a defect such as withdrawal or fluid leakage.

Therefore, the present invention is intended to solve the above drawbacks, while forming a spring-shaped coil tube having a coil-shaped tension force to the structure of the connection pipe, inserting the bushings into both ends of the spring-shaped coil tube, By inserting the fastening nuts, O-rings, washers, and clip rings into the circumferential portions of both ends of the bushings in order, the pipes are constructed by coiled spring-type coil pipes having tension force to provide piping during cold and hot water piping. It can be used to extend or reduce the spring type coil pipe without being bound to the interval or length to be connected, and it is fastened even in a narrow space without leakage when combined with the other coupling part to be coupled with the coupling nut formed at both ends of the spring type coil pipe. An object of the present invention is to provide a structure of a connection pipe for cold and hot water pipes that is easy to work with.

In order to achieve the above object, the present invention forms a spring-shaped coil tube 12 having a coil-shaped tension force, and inserts a bushing 13 into both ends of the spring-shaped coil tube 12. The bushing 13 is characterized in that the fastening nut 14, the O-ring 15, the washer 16, the clip ring 17 are sequentially inserted into the circumferential portions of both ends.

In the figure, reference numeral 20 shows a stopper to prevent foreign matter from flowing into the inside of the spring-shaped coil tube 12 during transport or storage of the tube.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a partially separated embodiment according to the present invention, Figure 2 shows an enlarged cross-sectional view showing the main portion of the embodiment according to the present invention,

The flexible tube 10 of the present invention is formed in a coil shape to form a spring coil tube 12 having a tension force.

A bushing 13 made of a hard material is fitted inside the both ends of the spring-shaped coil pipe 12 formed in the coil shape as described above to prevent the both ends from being pressed or crushed.

The fastening nut 14 is fitted into the circumferential portions of both ends of the bushing 13, and the O-ring 15, the washer 16, and the clip ring 17 are then fitted.

The fastening nut 14 is fastened to the other coupling portion during the piping operation, the O-ring 15 seals the coupling portion to prevent leakage, the clip ring 17 is the O-ring 15 and the washer 16 ) To prevent desorption from both ends of the spring-type coil pipe 12.

Connecting pipe 10 of the present invention configured as described above is coupled to one end is connected to the cold, hot water distributor 31 for supplying and distributing cold and hot water, as shown in Figure 3, the other end is cold , Is coupled to the hot water faucet 32 is coupled.

As described above, the connecting pipe 10 composed of the spring-type coil pipe 12 is connected to the spring-type coil pipe 12 by increasing or decreasing the spring-type coil pipe 12 without being bound to the interval or length to be piped by the tension force. As can be, it is very easy to install the connection work in the narrow space, such as the faucet (30).

Figure 4 shows another use state of the flexible pipe 10 of the present invention, the flexible pipe 10 of the present invention to the bolt portion 43 of the faucet 42 is fitted into the upper portion of the sink 40 By screwing the fastening nut 14 of one side formed at both ends and screwing the other fastening nut 14 to the bolt portion 45 of the water supply 44 side formed on the wall surface 50 side, The fastening operation of the connection pipe 10 for connecting 42 and the water supply 44 is completed.

The spring-type coil pipe 12 has a good tension and can be connected while expanding and contracting properly according to the installation space.

Therefore, the present invention as described above can be used to extend or reduce the spring-type coil pipe without a separate tool even in places where the installation space is narrow, such as the faucet box 30 or the sink 40.

As described above, a spring-shaped coil tube having a coil-shaped tension force is formed, and a bushing is inserted into both ends of the spring-shaped coil tube, and the fastening nut, O-ring, washer, By inserting the clip ring sequentially, the spring-type coil pipe is increased or decreased without being bound by the gap or length to be piped during cold and hot water piping work by the connection tube composed of a coil-shaped spring-type coil pipe with tension force. It can be used for piping, and the coupling work is easy even in a narrow space without water leakage when combined with the other coupling portion to be coupled to the coupling nut formed at both ends of the spring-type coil pipe.
