Description

One touch type pipe connector

The present invention relates to a one-touch pipe connector, and if described in more detail, the one-touch pipe connector allows simple and quick coupling in a one-touch type when connecting a synthetic resin pipe.

In general, various synthetic resin pipes, such as XL pipe, PB pipe, and PE pipe, which are used to transport boilers or various fluids, are produced in a certain length and cut and used as necessary. , It was being used to extend it using a connector of various structures.

The connector used for the connection of the various synthetic resin pipes is disclosed in Korean Utility Model 1989 No. 23200 (published on Dec. 2, 1989) or Public Utility Model No. 23591 1995 (published on Aug. 23, 1995). As published, a number of technologies have been developed to firmly connect the hose or the excel pipe by being combined with the outside of the hose or excel pipe at the connector of the hot water boiler hose or the fitting of the excel pipe and crimped inside the connector or fitting.

However, in the conventional technologies, when the clamping ring loosens when it is used for a long time or when the connector or fitting is weakly tightened, the fluid inside the hose or excel pipe frequently leaks at the end. It had a problem that it was somewhat insufficient to securely fix the connector to the connector or fitting.

Accordingly, in recent years, as published in Korean Utility Model 2000 No.9281 (published on May 25, 2000), as well as the inner and outer sides of the clamping ring, a protrusion is formed on the clamping ring. A protrusion was formed on the outer surface of the guide tube of the corresponding connector to make the connection of the connector body by the clamping ring firm, but this also made it difficult to fundamentally block fluid leakage due to the coupling of the clamping ring as the main configuration.

In addition, as published in the Republic of Korea Utility Model No. 238545 (announced on October 12, 2001), the fixing ring is connected to the outside of the pipe, and the nut is tightened to the connector to connect the pipe. Water leakage was prevented by interposing two O-ring type packings in front of the connector, but this O-ring type packing did not come into contact with the tip of the pipe, so the leakage could not be completely blocked.

Here, the pipe (P) is pushed from the rear of the pressure nut (5) toward the main body (2) so that the coupling guide pipe (4) is inscribed, and the pipe (P) is joined until the tip of the pipe (P) contacts the main body (2). When the pressure nut 5 is screwed to the fastening pipe 3 of the main body 2, as in the above, the fastening ring 6 and the pressure ring ( 7) and the contact means (8) are pushed forward, at this time, as the opening (61) of the tightening ring (6) is narrowed, the pressing support piece (62) bent forward inside the pipe (P) is pressed to the outer peripheral surface of the pipe (P).

Thereafter, as the coupling guide pipe 4 is in contact with the pipe (P), the coupling guide pipe (4) and the pipe (P) are sealed by a sealing ring (41) or a wide sealing ring (42) to the inside of the pipe (P). Push in from the rear of the pressure nut (5) toward the main body (2) to block the leakage of flowing fluid, and then engage the pipe (P) until the tip reaches the main body (2), and then press the nut (5) as shown in FIG. When tightening the screw to the fastening pipe 3 of the main body 2 as much as possible, the compressing ring 9 is pushed forward by the pressure nut 5, and the compressing ring 9 attaches the tightening ring 6 to the main body ( It is pressurized and adhered between the fastening pipe 3 of 2).

At this time, the pressure support piece 62 of the tightening ring 6 is bent into the space created by the inner inclined surface 33 of the front fastening pipe 3 when the pipe P is coupled, and then returns to its original position by the elastic restoring force. By pressing and fixing the outside of the pipe (P) coupled to the coupling guide pipe (4) in a forward-bent state, it blocks the separation of the pipe (P) to the rear, and in addition to this, the compression ring at the rear of the tightening ring (6) The support protrusion frame 91 of (9) is closely supported by the pressure support piece 62 to prevent the pipe P from being separated backward, thereby remarkably improving the coupling durability.
