[0001] The present invention relates to a sleeve structure for a drain pipe,

The present invention relates to a sleeve structure for a drain pipe, and more particularly to a drain pipe structure for preventing drainage pipe from flowing backward to a discharge outlet side connected to the body when discharging wastewater, To a sleeve structure for a drain pipe whose structure is improved so as to minimize clogging in the flow path.

Generally, in a multi-story high-rise building, a granulation pipe pipe is installed to be connected to a connection sleeve in an installation space composed of a retaining wall so as to be separated from an upper room to a lower room for discharging sewage used in the inside of each floor, A connection pipe is connected to the connection sleeve through which the sewage is discharged from the room, and the drain trap installed in the room of each floor is discharged through the discharge pipe to the sewage pipe pipe and discharged to the drain pipe I will lose.

However, the problem of this is that the falling noise generated by the falling water from the upper layer to the lower layer through the sewage piping pipe is transmitted through the discharge pipe arranged to discharge the sewage in the room of each floor, .

These falling noises are particularly noticeable in quiet nights.

Therefore, in order to reduce such noises, a packing having protruding pieces arranged at regular intervals on the inner circumferential surface of the connecting sleeve to which the granular pipe pipes are connected is mounted, and the dropped water is spread as it strikes the protruding pieces, It was suggested that noise should not be caused by this phenomenon.

However, the falling noise emitted to the lower layer was not completely blocked, so that the falling noise was transmitted to the inside of the room through the pipe as it was, especially in a quiet night, such noise became louder.

In addition, this piping connection structure has a considerable inconvenience in life because not only the falling noise of the sewage falls but also the odor is exposed to the room through the discharge pipe and the drain trap like noise

As an example of the prior art related to the existing drain pipe sleeve, a fixing bracket is attached to the lower outer edge portion of the sleeve main body, as disclosed in Korean Registered Utility Model No. 20-0365823 "Sleeve for drain pipe" (registered on October 15, 2004) Which is formed in the inner periphery of the inner periphery of the inner periphery of the sleeve main body and is formed by pouring the water pipe up and down. And a latching protrusion formed on the upper end of a packing made of rubber formed by reducing the guide tube to be inserted into the inner tube is formed on the upper side of the latching tube to form a space between the inner wall of the sleeve body and the packing, And a sound absorbing hole is formed in the fitting portion of the lid supporting hole so as to be opened to the side in contact with the packing, And the interlayer due to the drainage of noise to solve noise pollution problems.

Further, another example of the prior art relating to a conventional drain pipe sleeve is disclosed in Korean Patent Laid-Open Publication No. 10-2013-0095865 entitled " Sleeve for preventing noise and odor in the interlayer "(published date: 2013.08.29) The shielding means is automatically opened and closed in accordance with the discharge of the sewage water to the inside of the connection pipe through which the drain pipe connected to the drain trap is connected to one side of the connection sleeve on which the piping pipe is connected up and down, When the waste water discharged from the room is discharged to the drain trap and discharged to the granular pipe pipe connected to the connection sleeve through the discharge pipe, the shielding means is automatically opened by the discharged sewage, and the shielding means is automatically closed will be.

However, the existing sleeve for the drain pipe is not only complicated in the construction of the shielding means for shielding the reverse flow of the wastewater and odor, but also has a disadvantage in that the connection portion is loose when the connection portion with the drain pipe is simple, And there is a drawback that the assemblability is deteriorated.

In addition, since the existing drain pipe sleeve is vertically connected to the drain pipes and laterally connected to the discharge pipe, there is a possibility that the foreign substances contained in the wastewater can easily flow into the side discharge port side and the flow path is clogged.

Korean Registered Utility Model No. 20-0365823 "Sleeve for drain pipe" (registered on October 15, 2004) Korean Patent Laid-Open No. 10-2013-0095865 entitled "Sleeve for preventing noise and odor in the interlayer" (Publication date: Aug. 29, 2013)

The object of the present invention is to solve the above problems and to solve the above problems, and it is an object of the present invention to prevent the reverse flow of wastewater owing to easy assembly of drain pipes, And to provide a sleeve structure for a drain pipe with an improved structure.

In order to achieve the above-mentioned object, the present invention has a main body in which a hollow is formed to connect drain pipes in a vertical direction, and a connection pipe projected to connect a drain pipe in a lateral direction of the main body,

Since the connection hole 405 of the second coupler member 400 is formed at an eccentric position with respect to the hollow 105 rather than at the center of the second coupler member 400, the position of the communication pipe 500 coupled to the connection hole 405 is hollow The foreign matter contained in the wastewater discharged through the upper drain pipe 10 is easily accumulated in the hollow 105 to prevent the hollow 105 from being clogged .

The connection pipe 200 of the present invention is connected to the discharge pipe 20 in the lateral direction with respect to the main body 100 and is connected to the hollow main body 100 by the inclined surface 210 formed at the connection portion with the main body 100, 105 are formed to be narrower than the inner diameter of the intermediate portion of the connection pipe 200, it is possible to prevent the wastewater drained through the hollow 105 from being easily backwardly flowed to the discharge pipe 20, The wastewater is guided along the inclined surface 210 in the course of supplying the wastewater supplied to the main body 100 through the first and the second pipes 20 and 20 to the inside of the hollow 105,

Therefore, in the present invention, the inclined surface 210 is formed in the connection pipe 200 connected to the hollow 105 of the main body 100 so that wastewater discharged through the hollow 105 flows through the connection pipe 200 to the discharge pipe 20 It is possible to prevent the backflow of the refrigerant into the inside of the compressor.

The present invention also relates to a method of connecting a communicating tube 500 coupled to a connecting hole 405 at an axially eccentric position with respect to the center of the hollow 105, It is possible to prevent the phenomenon that the foreign matter contained in the wastewater discharged to the lower drain pipe 10 is easily accumulated in the hollow 105 and the hollow 105 is clogged.
