Description

Drain pipe fittings replacement

The present invention relates to a drain pipe connector for connecting the valve installed in the sink installed in the washbasin and the sewer pipe for discharging the washing water, more specifically, it can be quickly and easily connected to the installation height and the position of the sewage pipe. The present invention relates to a sink drain pipe connection that allows a simple connection to a drain valve of a sink and a sewage pipe using a bent pipe.

In general, the sink is installed in the washbasin is equipped with a valve, it is installed by connecting the valve and the drain trap connected to the sewage pipe of the washbasin.

At this time, since the position of the drain trap connected to the sewage pipe is not standardized in height and position of the wash basin, the positions of the sinks and sewage pipes of all wash basins are installed differently.

The conventional drainage pipe connection means for a conventional sink is composed of a drain pipe 100, the valve is built, and the connection pipe 300 for connecting the drain pipe 100 and the sewer pipe, as shown in FIG. The connection pipe 300 is provided with several types of connection pipe 300 to have a variety of lengths depending on the height of the wash basin is installed.

Thus, in order to properly connect according to the height of the sink and the position of the sewer pipe, the length of the connector may be prepared in advance to have various lengths such as 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, or 30 cm connector having the longest length in advance. After that, when connecting the sink and the sewer pipe in the field is the situation to be cut to connect to the appropriate size.

However, even if the upper and lower lengths are adjusted by cutting the connecting pipe, when the position of the drain and the sewer pipe does not form a vertical line, the drain trap should be connected by adjusting the position of the drain trap. There was also a limit to the means.

As a means for solving this problem, a means for connecting the drain and drain pipes of the sink using a flexible connection pipe is proposed.

That is, a means for connecting the drain and drainage pipes of the sink using a variable connecting corrugated pipe disclosed in Korean Utility Model Publication No. 1999-4233 has been proposed.

According to the conventional design, the circumferential portion of the corrugated pipe is formed in the center portion of the corrugated pipe in the form of continuous pleats, and the pleat circumference is provided. It is designed to connect to pipes.

Connection pipe tube applied to such a conventional design has a disadvantage that the bending action is freely made, the length can not be adjusted.

Therefore, even if the bent pipe is applied as described above, inconvenient to prepare separately in consideration of the length of the sink and sewage pipe could not be avoided.

In addition, the conventional design described above is to install the bent in the "U" shape to prevent the overflow by bending the bending tube itself, foreign substances such as hair contained in the washing water discharged through the inside is caught in each spiral portion It is not possible to discharge, the accumulation of these foreign matters is a problem that the drainage effect is reduced.

In addition, the above-mentioned corrugated pipe should prepare a plurality of corrugated pipes for connecting one sink drain and drain traps, the manufacturer of the sink for drainage pre-prepared and stored a connector having a variety of length, the consumer's order As soon as possible to deliver.

Therefore, producers need to produce and store connection pipes of various sizes unnecessarily, which requires a considerable storage location, and the seller also needs to provide connection pipes of the length required by consumers in stores. There is a disadvantage that requires.

Such unnecessary production costs and storage costs are passed on to the consumer as a result of which the selling price of the entire sink drain is expensive.

The present invention relates to a conventional drainage connection pipe for the sink as described above, an object of the present invention to provide a drain connection pipe that can be adjusted freely the installation length.

Another object of the present invention is to provide a drain pipe connector that can be easily connected by anyone in the public, so that the means for connecting the drain pipe and the sewer pipe can be made extremely simple.

Still another object of the present invention is to provide a low-cost supply and production to sell a finished product with only one connector in one sink drain.

The present invention for solving the above object, using a connecting pipe using a flexible bent pipe flexible length adjustment and bending control of the drain connector, the drain pipe connector that can be assembled with the drain pipe of the sink extremely simply To provide a solution to the above, the drain pipe connector,

Corrugated pipes having adjustable length and free bending action;

An upper fastening ring having an outer spiral portion and an inner spiral portion screwed to an inner circumference of the upper and lower ends of the valley curved tube;

For connection pipe body provided with a threaded portion on the outer circumferential surface of the upper fastening ring and screwed to the inner circumferential surface, the outer tube formed in the form surrounding the outer tube and the bent pipe formed between the connection pipe body and the exterior An upper drain pipe connector including an extension part, an extension part formed on an upper side of the outer appearance, and a connection screw part formed on an outer circumferential surface thereof;

A lower fastening ring having the same configuration as the upper fastening ring screwed inside the lower end of the bent pipe;

Consists of the same pipe and the main body and the outer tube and the bent pipe receiving portion and the extension portion, the extension portion is formed to extend longer, and the outer peripheral surface is to solve the problem by providing a connector consisting of a flat type.

The drain pipe connector of the present invention having the above configuration is to provide a feature that can be easily connected regardless of the position of the wash basin and sewage pipe installed, and can be connected to the existing sink drain pipe using a simple connector.

In addition, the drain pipe connector of the present invention, when applying a conventional pipe-type connector, the length of at least 10cm, 15cm 20cm, 30cm, the length of at least 10 types of connection pipes having a length of at least 10 cm, if not separately prepared if one connector Since it can be used to correspond to the length so that the producer or seller does not need a separate storage place, it is possible to obtain the ease of storage and the cost savings accordingly.

Flexure tube (1) can be adjusted in length and free to bend;
The outer center of the connecting tube body 83 is bent downward to form an exterior 84, and the upper and lower ends 1a of the bent tube 1 between the exterior 84 and the connecting tube body 83 ( 1b) to form a bent pipe accommodating portion 85, and extends the connecting pipe body 83 to form an extension portion 86, the outer peripheral surface connecting screw portion to be connected to the drain pipe 100 An upper drain pipe connector 80 formed with a 86a;
A connecting pipe main body 83 ', an exterior 84', and a curved pipe accommodation part 85 'are formed in the same shape as the upper drain pipe connecting member 80, and the connecting pipe main body 83' is connected to the connecting pipe main body. Extending longer than the extension portion 86 of the (83) to form a lower drain pipe connector (80 ') formed with an extension portion 86', the upper and lower ends (1a) (1b) of the bent pipe (1) The drain pipe connector for sinks, characterized in that the bent pipe receiving portion (85) (85 ') after the introduction, fixed by filling the adhesive.
