Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

2 is an exploded perspective view of a connector between a rising drain pipe and a floor sleeve according to an embodiment of the present invention, FIG. 3 is an exploded cross-sectional view of a connector between a rising drain pipe and a floor sleeve according to an embodiment of the present invention, FIG. 3 is a cross-sectional view.

Referring to the drawing above, the connector between the rising drain pipe and the floor sleeve according to the present invention (hereinafter, abbreviated as 'connector') 100 has the upper end of the lower part of the standing drain pipe (1) fitted and coupled to the ceiling sleeve (not shown). and the bottom sleeve (8) for a strong and simple connection, the lower connecting pipe 200, the upper connecting pipe 300, the tightening socket 400, the upper O-ring 500, the O-ring pressure ring 600 and the lower An O-ring 700 may be included.

The lower connecting pipe 200 having a cylindrical structure is installed to be intubated into the upper side of the floor sleeve 8 whose lower part is embedded in the floor slab (s).

In this embodiment, the lower connection pipe 200 includes a cylindrical body 210, an intubation part 211 that is intubated into the upper side of the bottom sleeve 8 while being provided at the lower part of the cylindrical body, and one of the cylindrical body 210 . It may be composed of a branch pipe 212 provided on the side, and an annular stepped portion 213 provided on the upper end of the cylindrical body 210 .

In addition, a coupling ring 214 into which the lower end of the tightening socket 400 is inserted may be integrally provided at the outer end of the stepped portion 213 .

The upper connection pipe 300 of the cylindrical structure is installed such that the upright drain pipe 1 is intubated into its upper side, and the lower side is intubated into the lower connection pipe 200 .

Here, since the upper side of the upper connecting pipe 300 and the lower side of the rising drain pipe 1 are in a spaced apart state, the upper connecting pipe 300 must be slightly lifted to connect with the rising drain pipe 1, so the lower connecting pipe 200 The intubation depth must be greater than the lifted height.

In order to structurally lift the upper connection pipe 300 , a screw part 310 may be provided on its outer circumferential surface. This may be lifted by a one-way rotation operation of the tightening socket in a state of engagement with the mating thread 410 of the tightening socket 400, which will be described later. This will be revisited later.

In addition, an annular O-ring seat portion 320 is provided inside the upper side of the upper connection pipe 300, and a fitting protrusion 330 that protrudes upwardly on the O-ring seat portion to fit the upper O-ring 500 may be provided. .

The upper O-ring 500 may be provided with a fitting groove 510 in which the fitting protrusion is recessed in the lower portion of the upper O-ring 500 to be fitted to the fitting protrusion 330 .

Here, the inner diameter of the upper O-ring 500 should be at least the same as or larger than the inner diameter of the upper connecting pipe 300 in order to smoothly intubate the upright drain pipe 1 into the upper connecting pipe 300 . In this case, the role of watertightness and airtightness is impossible unless the upper O-ring 500 is pressed and deformed. Therefore, the O-ring pressure ring 600 is required.

The upper O-ring 500 needs a structure to be effectively pressed by the O-ring pressing ring 600 .

To this end, the O-ring pressure ring 600 is screwed to the upper part of the upper connection pipe 300 and presses and deforms the upper O-ring 500, so that the inner diameter of the upper O-ring is compressed to the outer circumferential surface of the upright drain pipe 1 and the upper part It is possible to watertightly and airtight between the connection pipe 300 and the rising drain pipe (1).

Here, in order to effectively pressurize the upper O-ring 500 by the O-ring pressure ring 600 , the upper O-ring 500 has a cross-sectional shape to form a mountain shape, and the O-ring pressure ring 600 has an upper portion. An outer circumferential pressing protrusion 610 for pressing the outer surface of the O-ring is provided, and the cross-section of the pressing protrusion is configured in an inverted mountain shape to have a structure that is matched with the outer circumferential surface of the upper O-ring 500, so that the upper O-ring is stable and It was made to pressurize uniformly.

In addition, the O-ring pressure ring 600 is provided with an upper pressing protrusion 620 for pressing the upper portion of the upper O-ring 500 downward, and has a structure to simultaneously press the outer peripheral surface and the upper portion of the upper O-ring 500 . Accordingly, the upper O-ring 500 can completely block the gap between the inner circumferential surface of the upper connection pipe 300 and the outer circumferential surface of the upright drain pipe 1 , thereby improving watertightness and airtightness in this area.

In addition, among the lower surface of the oil pressure ring 600 and a predetermined portion of the upper connection pipe 300 corresponding thereto, a locking groove 630 is provided to be arranged in an annular shape on either side, and the locking groove 630 and corresponding A locking protrusion 340 may be provided in the portion to be selectively recessed into the locking groove to prevent the O-ring pressure ring from being arbitrarily loosened by water flow vibration.

In addition, the inner circumferential surface of the upper connecting pipe 300 is inclined by a predetermined angle with respect to the axis line c of the upper connecting pipe, and the straight water flow drained through the inside of the upper connecting pipe 300 is converted into a rotating oil. A protrusion 350 may be provided.

In the case of normal drainage through only the hollow part of the standing drain pipe (1), a collision noise is generated as the drained water collides with the wall surface of the standing drain pipe, and when a large amount of water is drained at once, a vortex is generated in the flow path. Backflow may occur because drainage is not performed smoothly.

However, when the water flow direction guide protrusion 350 is provided, the drained water can be drained along the wall surface of the flow path while being guided to change the rotational flow, thereby helping to reduce collision noise and forming a constant rotational flow. It also helps with drainage.

Meanwhile, in the above description, the configuration in which the upper O-ring 500 is sealed while being pressed by the oil pressure ring 600 has been described.

That is, as in FIGS. 10 to 11 , the upper O-ring 500 is seated inside the upper side of the upper connection pipe 300 is the same, but the inner peripheral surface of the upper O-ring 500 has a wing 520 that slopes downward toward the end. ) is formed and there is a difference in sealing between the upper connection pipe 300 and the rising drain pipe 1 by this wing.

In addition, in order to prevent the upper O-ring 500 from being separated to the upper side of the upper connection pipe 300, the O-ring fixing ring 530 may be press-fitted on the upper side of the upper O-ring 500 of the upper connection pipe 300. . Accordingly, the upper O-ring 500 is prevented from moving upward by the O-ring fixing ring 530 .

The tightening socket 400 having a cylindrical structure is to be fastened to the outer peripheral surface of the upper connection pipe 300, and for this purpose, a counter threaded part 410 fastened to the threaded part 310 of the upper connection pipe 300 may be provided on the inner peripheral surface. there is.

As described above, the upper connecting pipe 300 is slightly raised and connected to the standing drain pipe 1, and the lower connecting pipe 200 is simply intubated into the bottom sleeve 8, so the coupling relationship between them is loose. Have no choice but to. A component for supplementing this is the tightening socket 400 .

The tightening socket 400 is in a state in which the threaded part 410 is fastened to the threaded part 310 of the upper connection pipe 300, so that it is possible to move the position in the vertical direction according to the rotational operation direction.

Therefore, when the tightening socket 400 is operated to rotate in one direction to come down, the lower end thereof is rotated until it is inserted into the coupling ring 214 provided on the upper side of the lower connection pipe 200, relatively upper The connection pipe 300 can be pushed up to make a close contact between the upper connection pipe and the standing drain pipe 1, and its lower end is in a state of being strongly in close contact with the upper side of the lower connection pipe 200, so the coupling between each component relationship can be strengthened. This is a favorable condition for improving watertightness and airtightness.

In other words, between the outer circumferential surface of the upper connection pipe 300 and the inner circumferential surface of the tightening socket 400 is watertight and airtight by the lower O-ring 700 deformed by pressing by the pressing force, and the tightening socket 400 and the lower connection pipe ( 200) will naturally affect the improvement of watertightness and airtightness.

The lower O-ring 700 is fitted on the outer circumferential surface of the upper connection pipe 300 , and when the tightening socket 400 moves downward, it is pulled down by the lower end of the tightening socket, and a stepped portion 213 provided at the upper end of the lower connection pipe 200 . ) and the lower end of the tightening socket 400 is pressed and deformed by the downward pressing force of the tightening socket 400 to airtight and watertight the previously described region.

At the lower end of the tightening socket 400, an upper pressing surface 420 for pressing the upper portion of the lower O-ring 700, and an upper pressing surface 420 to block the pressed lower O-ring 700 from being extended and displaced outward. A blocking wall 430 protruding downward may be provided at the outer end of the .

On the other hand, as described above, the lower O-ring 700 rides on the downward movement of the tightening socket 400 in the state that it is initially fitted on the outer peripheral surface of the upper connection pipe 200 and slips on the outer peripheral surface of the upper connection pipe. Therefore, the structure must be different from the general O-ring.

That is, the lower O-ring 700 is formed obliquely upward on the O-ring body 710 pressed by the lower end of the tightening socket 400 and the inward outer circumferential surface of the O-ring body, so that the upper connection pipe 300 is formed. It may be composed of a wing portion 720 that is in contact with the outer circumferential surface slip (slip).

Here, if only the O-ring body part 710 is configured without the wing part 720 , it is impossible to slip on the outer circumferential surface of the upper connection pipe 300 because it has the same structure as a normal O-ring. However, smooth slip is possible by the existence of the wing portion 720 that is inclined in a direction opposite to the traveling direction.

When the lower end of the tightening socket 400 enters the coupling ring 214 of the lower connection pipe 200 and the lowering is completed, the O-ring body 710 is pressed and deformed by the lower end of the tightening socket 400, so this part A substantial sealing is achieved in the , and the wing portion 720 is in close contact with the outer circumferential surface of the upper connecting pipe 300 , thereby contributing to the improvement of the sealing force.

On the other hand, on either side of the connection portion of the tightening socket 400 and the lower connection pipe 200, a multi-stage engaging groove 220 is provided to be annularly arranged, and in a portion corresponding to the engaging groove, the engaging groove 220 is A locking protrusion 440 may be provided to prevent the tightening socket 400 from being arbitrarily loosened by selectively concave inlet and water flow vibration.

Hereinafter, a connection method between the rising drain pipe and the bottom sleeve according to the present invention will be described with reference to FIGS. 5 to 7 .

(1) Step 1

The intubation part 211 of the lower connection pipe 200 is intubated into the upper side of the bottom sleeve 8 embedded in the bottom slab (s).

(2) Step 2

Insert the lower portion of the upper connection tube 300 into the upper side of the lower connection tube 200 with the lower O-ring 700 inserted in the lower portion of the .

At this time, the upper connection pipe 300 is intubated until the lower O-ring 700 is seated on the stepped portion 213 formed at the upper end of the lower connection pipe 200 .

(3) Step 3

The upper connection pipe 300 is lifted toward the upper connection pipe 300 located on the upper side of the upper connection pipe 300 while maintaining the intubated state in the lower connection pipe 200 to the inside of the upper side of the upper connection pipe. Let the lower part of the upright drain pipe (1) be intubated.

At this time, the tightening socket 400 screwed to the upper connection pipe 300 is also raised together with the upper connection pipe, and the lower O-ring 700 fitted to the outer circumferential surface of the upper connection pipe 300 is also in a raised state. .

(4) Step 4

The worker rotates the tightening socket 400 in one direction while holding the upper connection pipe to keep the rising drain pipe 1 and the upper connection pipe 300 connected to each other so as to descend. In this process, the lower O-ring 700 fitted on the outer circumferential surface of the upper connection pipe 300 by the lower end of the tightening socket 400 is pushed down while being pushed down.

Thereafter, the lower portion of the tightening socket 400 is inserted into the coupling ring 214 provided on the upper portion of the lower connection pipe 200 and the lower O-ring 700 is pressed, thereby sealing the lower side, and at the same time the tightening socket 400 ), the upper connection pipe 200 rises slightly and comes in close contact with the lower part of the upright drain pipe 1 to have a strong coupling relationship.

(5) Step 5

As a final step, the O-ring pressure ring 600 loosely coupled to the upper side of the upper connection tube 200 is strongly tightened to press the upper O-ring 500 located inside the upper side of the upper connection tube 200 .

As a result, the upper O-ring 500 pressed by the O-ring pressure ring 600 is elastically deformed to seal the area, and at the same time, the upright drain pipe 1 is strongly tightened and clamped.
