Description

The pipe connecting instrument is fastened to the holder using an integrated coupling plate

The present invention relates to a tube for transporting a fluid or a liquid, in which an adapter is fused and connected to a tube on one side, and a coupling plate is integrally formed by injection molding on the other tube so that the holder can be easily fastened using a holder. It relates to an integrated tube that is fastened to the holder using an integrated coupling plate.

In the daily life, a pipe for transporting a fluid or a liquid may be used to transport gas, water, and wastewater, and industrially, various flow paths or large water channels may be formed by a pipe.

These tubes are manufactured and supplied in a certain length for the convenience of transportation and construction, and they are connected and used in various ways depending on the material and size of the tube.

As a technique related to a method of connecting such a tube, the applicant has applied for and registered "Integral tube fastening to a holder using a coupling plate" (Korean Patent Publication No. 10-0762990).

As described above, the adapter is fused to only one end of the corrugated pipe so that the pipe can be connected relatively easily.

However, the above-described technology has a problem in that a separate coupling plate must be inserted into the adapter and the holder when the other side pipe is connected using the holder, and thus the coupling plate installation process must be performed.

In particular, the connection of the pipe is required to minimize the singular time, so a structure that can connect the pipe in a faster time than the structure as described above is required.

In addition, when the coupling plate is not installed at the correct position inside the holder, the operator has to press the other side pipe and the coupling plate to one side by using the holder, and a lot of force enters, in which case the holder made of synthetic resin material is broken or forced When tightening the bolt and nut to the holder while pressurizing the bolt and nut fastening portion is broken and eventually there is a problem that a gap occurs between one side pipe and the other side pipe.

In addition, it is impossible to confirm whether the other side is in contact with the one side when the other side is inserted into the one side, and the other side is separated from the one side while preparing for the fastening of the holder while the one side and the other side are in contact. If there was a problem that can not be detected.

In particular, when a gap occurs between the one side and the other side of the tube, there is a problem in that the water inside the hollow due to the hollow is formed inside the corrugated tube.

In addition, when the above technique is applied to a flat tube that is not wrinkled, the holder and the coupling plate cannot forcibly move the other side to one side, so that a gap occurs between the one side and the other side, and foreign matter is caught in the gap. There was a problem that the water quality or the state of the fluid or liquid worsens.

That is, the above technology has a problem that the coupling plate and the holder does not completely adhere the other side to one side of the tube when the flat tube is applied, and the holder cannot be fastened in a state where the one side and the other side of the tube are in close contact. .

This is a situation that requires the technology to be able to be completely in close contact while connecting the two pipes that are not wrinkled more easily.
