Description

Connector of pipe

The present invention relates to a pipe connector, and more particularly, by connecting the auxiliary connector that is in close contact with the inner peripheral surface of the connector in the inside of the connector when the pipe is formed in the same diameter of the pipe and the connector, the combined pipe is A pipe end that does not easily escape from the pipe end.

In general, in the case of a pipe connector, as shown in FIG. 1, a pipe having a diameter smaller than that of the connector is inserted into the connector and fixedly coupled thereto, and then a fixing ring is formed on the outer surface thereof to connect the pipe and the connector with the fixing ring. In addition, it prevents unauthorized release of pipes and connectors.

However, the above-described prior art is not aesthetically beautiful due to the difference in the outer diameter of the pipe connector and the pipe, the problem occurs that the connection portion is caught on another object.

As a technique for solving the above problems has been filed by the applicant of the present invention, it was introduced in the Republic of Korea Patent Application Publication No. 1998-16837.

The prior art is to connect the pipe to the T connector (3) and the elbow (2), the connecting pipe (4) cut to a certain length and the diameter of the T connector (3) and elbow (2) The present invention relates to a handrail pipe for fixing pipes of the same diameter.

However, the above-described prior art is not only there is no stability of the coupling due to the endless flow of the pipe (1) in the connecting pipe 4, if the inner diameter of the connected pipe (1) is larger than the outer diameter of the connecting pipe (4), the pipe ( There is a problem that 1) is easily separated from the connecting pipe (4).

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide a pipe connector with the same outer diameter by coupling the pipe to the auxiliary connector by forming an auxiliary connector inside the connector.

Another object of the present invention is to provide a pipe connector in which a pipe coupled to the auxiliary connector is stably coupled and is not easily separated and flowed.

The present invention for achieving the above object is a connector formed in a tubular shape; An auxiliary connector formed in a tubular shape and fixed to the inner circumferential surface of the connector and at the same time the coupling part protrudes outward of the connector; And, the pipe connector is configured to include a protruding outwardly protruding outwardly on the outer peripheral surface of the auxiliary connector to secure the pipe coupled to the coupling portion of the auxiliary connector.

Here, the elastic protrusion piece is preferably formed integrally with the auxiliary connector.

And, the auxiliary connector is preferably configured such that the end is sealed.

Accordingly, the pipe is stably coupled to the auxiliary connector to prevent flow and separation, and at the same time, the outer diameter of the connector and the outer diameter of the pipe are the same, so it is aesthetically beautiful and stable.

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

Figure 2 is a perspective view of an elbow-shaped pipe connector according to the present invention, Figure 3 is a perspective view of a T-shaped pipe connector, Figure 4 is a cross-sectional view of the elbow-shaped pipe connector is connected to the pipe, Figure 5 is a pipe connected to T 6 is a cross-sectional view of an elbow-shaped pipe connector of another embodiment, and FIG. 7 is a cross-sectional view of a T-shaped pipe connector of another embodiment.

As shown, the pipe connector according to the present invention is largely composed of the connector 100, the auxiliary connector 110 and the elastic protrusion piece 120.

First, the connector 100 will be described.

The connector 100 is formed of a penetrating tubular shape, it is composed of a T shape or elbow shape. That is, it is composed of a general T connector or elbow type.

An auxiliary connector 110 is inserted into and coupled to an inner circumferential surface of an end portion adjacent to the connector 100, and the auxiliary connector 110 is formed in a large cylindrical shape with both sides open, and an outer circumferential surface of the auxiliary connector 110 is connected to the connector. The inner circumferential surface of the 100 is coupled in close contact. And the connector 100 and the auxiliary connector 110 is coupled by welding and the bonding force is maintained. In addition, a part of the auxiliary connector 110 coupled to the connector 100 is formed with a coupling portion 111 protrudes to the outside of the connector 100, the pipe 200 is inserted and coupled to the coupling portion 111. .

If necessary, the auxiliary connector 110 may be configured such that the sealing plate 112 for sealing one side of the auxiliary connector 110 at the end of the auxiliary connector 110 is integrally formed with the auxiliary connector 110. . The sealing plate 112 is configured in the shape of a disc, coupled to the end of the auxiliary connector 110 to improve the supporting force of the auxiliary connector (110).

The elastic protrusion piece 120 is integrally formed with the auxiliary connector 110 in the coupling portion 111 of the auxiliary connector 110, and is formed in a form in which a part of the auxiliary connector 110 is cut out to protrude outward. .

That is, part of the elastic protrusion piece 120 is coupled to the auxiliary connector 110, the remaining portion is formed to protrude to the outer portion of the auxiliary connector 110, the pipe 200 of the auxiliary connector 110 When coupled to the coupling portion 111, the pipe 200 is prevented from being stepped off by the elastic force of the elastic protrusion piece 120 and at the same time to be a stable coupling.

As the elastic protrusion piece 120 is formed, a groove 113 corresponding to the elastic protrusion piece 120 is naturally formed in the coupling part 111 of the auxiliary connector 110.

The operation effect by the above configuration is as described later.

When the user couples the pipe 200 to the coupling part 111 of the auxiliary connector 110, the elastic protrusion piece 120 formed on the coupling part 111 transmits the elastic force toward the outside of the pipe 200. As a result, the pipe 200 is tightly fitted to the elastic protrusion piece 120 so that the pipe 200 and the auxiliary connector 110 are stably coupled to each other, thereby preventing unauthorized departure of the pipe 200.

Here, the outer diameter of the pipe 200 coupled to the auxiliary connector 110 is the same as the outer diameter of the connector 100 is used.

The present invention by the above configuration, by connecting the auxiliary connector that is in close contact with the inner circumferential surface of the connector inside the connector is formed in the same diameter of the pipe and the connector when connecting the pipe, the combined pipe is easily separated from the pipe connector There is no effect.
