AI Technical Summary
When the existing toilet drainage branch pipe is installed, the ground waterproof layer and the ground outlet branch pipe cannot form an effective waterproof flange, causing water to leak downward along the surface of the drainage branch pipe, especially in a thermal expansion and contraction environment.
A water stop section of the toilet drainage branch pipe is designed, and a vertical wing ring structure is adopted, including a horizontal ring and a vertical sleeve to form a waterproof closing opening. It is fixed in the surrounding objects through a positioning table and a slurry resistor to ensure that the waterproof layer is tightly fixed and avoids movement due to thermal expansion and contraction.
It effectively prevents water from leaking along the edge of the out-of-ground pipe, keeps the waterproof ability of the waterproof layer from being damaged, and is suitable for thermal expansion and contraction environments.

Technical Field
[0001] The utility model relates to a water stop joint, in particular to a water stop joint for a toilet drainage branch pipe. Background Art
[0002] The existing drainage branch pipes for toilets, especially the drainage branch pipes for toilet seats, have a section of the branch pipe protruding from the ground during installation and directly connected to the toilet seat. The ground waterproof layer and the branch pipe protruding from the ground cannot form an effective waterproof flange, causing ground water to leak downward along the surface of the drainage branch pipe. The situation is particularly serious when the pipe is made of plastic material, as the thermal expansion and contraction phenomenon is very large. Summary of the invention
[0003] The technical problem to be solved by the utility model is to overcome the above-mentioned defects of the prior art and provide a toilet drainage branch pipe water stop joint, which can change the connection mode between the water stop joint and the waterproof layer so that the water stop joint and the waterproof layer will not be damaged under the environment of thermal expansion and contraction.
[0004] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a water-stop joint for a toilet drainage branch pipe includes a water-stop joint main body and a vertical wing ring; the water-stop joint main body includes a ground pipe interface and a drainage interface, the ground pipe interface can be connected to the toilet drainage branch pipe, and the drainage interface can be connected to the drainage pipe; the vertical wing ring includes a horizontal ring and a vertical sleeve, the horizontal ring is sleeved on the main body and fixed, and the vertical sleeve is vertically fixed on the outer ring of the horizontal ring.
[0005] Preferably, the horizontal ring is provided with a positioning platform surrounding the outside of the vertical wing ring, and the water stop joint of the toilet drainage branch pipe can be fixed in the surrounding objects through the positioning platform.
[0006] Preferably, a slurry blocking member is further provided, the top of which is connected to the back of the horizontal ring, the slurry blocking member surrounds the drainage interface and can prevent objects outside the slurry blocking member from entering the drainage interface.
[0007] Preferably, fixing ears are arranged on the outer ring of the slurry blocking member, and the slurry blocking member is fixed to the surrounding objects through the fixing ears.
[0008] Compared with the prior art, the advantages of the utility model are: since the toilet drainage branch pipe water stop joint is equipped with a vertical wing ring, a waterproof closing is formed between the vertical wing ring and the outer wall of the main body, which can tightly fix the waterproof layer in the waterproof closing, and can prevent the waterproof layer from moving due to thermal expansion and contraction, thereby not destroying the waterproof ability of the waterproof layer, and effectively preventing water from leaking along the edge of the ground pipe.

[0014] The present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0015] like Figure 1 As shown, the water stop joint of the toilet drainage branch pipe includes a water stop joint body 30, a vertical wing ring 2, and a slurry blocking member 4.
[0016] The water-stop joint body 30 includes a ground pipe interface 1 and a drainage interface 3 . The ground pipe interface 1 can be connected to a toilet drainage branch pipe, and the drainage interface 3 can be connected to a drainage pipe 12 .
[0017] The vertical wing ring 2 includes a horizontal ring 21 and a vertical sleeve 22. The horizontal ring 21 is sleeved on the main body 30 and fixed, and the vertical sleeve 22 is vertically fixed on the outer ring of the horizontal ring 21. A waterproof joint is formed between the vertical wing ring 2 and the outer wall of the main body 30.
[0018] The positioning platform 5 is a protrusion surrounding the outside of the vertical wing ring 2, and the positioning platform 5 can be used to fix the water stop joint of the toilet drainage branch pipe in the surrounding objects.
[0019] The top of the slurry blocking member 4 is connected to the back of the horizontal ring 21, and the periphery of the slurry blocking member surrounds the drainage interface 3 and can prevent objects outside the slurry blocking member 4 from entering the drainage interface.
[0020] like Figure 2 , 3 As shown, another toilet drainage branch pipe water stop joint is composed of Figure 1 , 2 The toilet drainage branch pipe water stop joint shown is formed by removing the slurry blocking member 4, and can be applied to the same-floor drainage situation.
[0021] like Figure 2 and Figure 3As shown, when waterproofing is implemented after the water stop joint is installed, a waterproof joint is formed between the vertical wing ring 2 and the outer wall of the main body 30, and the waterproof layer 13 is closed in the waterproof joint of the vertical wing ring 2. Specifically, after the waterproof leveling layer 14 is flush with the outer wall of the vertical sleeve 22 of the vertical wing ring 2, the waterproof layer 13 is continuously spread on the upper surface of the leveling layer 14 to the inner wall of the vertical sleeve 22 of the vertical wing ring 2, and then the waterproof protective layer 10 fills the waterproof layer 13 and the vertical wing ring 2, and the waterproof layer 13 is tightly fixed on the inner side of the vertical sleeve 22 of the vertical wing ring 2 and the waterproof leveling layer 14. The waterproof protective layer 10 and the leveling layer 14 on the outer side of the vertical wing ring 2 work together to tightly fix the waterproof layer 13 on the closed vertical wing ring 2, so that the waterproof layer 13 will not be displaced due to temperature changes.
[0022] like Figure 4 As shown, the slurry blocking member 4 can be fixed on the template for making the structural floor through the fixing ear 6 during the pre-embedded installation to prevent the concrete mortar 11 from being near the drainage pipe interface 3, thereby ensuring that the drainage pipe 12 can be connected to the drainage pipe interface 3.
[0023] like Figure 5 As shown, when used for same-floor drainage, the slurry blocking member 4 is removed, and the drainage pipe interface 3 is first connected to the drainage pipe 12 and then the mortar 15 is backfilled.
[0024] like Figure 4 and Figure 5 As shown, after the waterproof protective layer 10 is completed, the decorative surface layer 8 can be installed on the protective layer 10 through the adhesive layer 9, and the drain outlet 7 of the toilet is sealed and connected with the ground interface 1 of the water stop joint.
[0025] like Figure 4 and Figure 5 As shown, during the installation process, the positioning platform 5 is fixed to the structural floor 11 or the backfill layer 15 to prevent the water stop joint from moving up and down.
