DETAILED DESCRIPTION

[0030] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figure 1 、 2 Figure 1 shows a schematic diagram of the present invention's bathroom drain pipe opening and sealing device. Floor 1 represents the original bathroom floor structure, constructed from cast concrete. A through hole 2 vertically penetrates floor 1 for installing drain pipe 3. An operator drills through floor 1 with an electric drill or hammer. The diameter of through hole 2 is determined by the diameter of drain pipe 3 (a 75mm diameter drain pipe will suffice, a 90mm diameter drain pipe will suffice, and a 130mm diameter drain pipe will suffice).

[0034] Sleeve 4 is fitted over drain pipe 3 and rests against the upper surface of floor 1. Extension pipe 5 is integrally connected to the bottom of sleeve 4 and fits over drain pipe 3. An adjustment gap 6 is left between extension pipe 5 and the inner wall of through-hole 2, ensuring sufficient space for adjustment during installation and facilitating the connection of drain pipe 3 to other pipes. Before installing sleeve 4, cement mortar is applied to the inner wall of through-hole 2. This serves to secure extension pipe 5 after the cement mortar solidifies and to seal adjustment gap 6 to prevent water leakage.

[0035] A step is provided on top of the casing 4 to prevent external water from seeping through the gap between the casing 4 and the floor slab 1. The step comprises a casting layer 18, an adhesive layer 19, a non-woven fabric layer 20, and a coating layer 21. Cement mortar is poured on top of the casing 4 to form the casting layer 18. The casting layer 18 covers the casing 4 (including the top and side surfaces) to prevent external water from seeping through the gap between the casing 4 and the floor slab 1.

[0036] After the pouring layer 18 is poured, glue is evenly applied on the top of the pouring layer 18 to form an adhesive layer 19. While applying the glue, non-woven fabric is laid to form a non-woven fabric layer 20. The non-woven fabric should be laid flat without wrinkles or hanging. At the same time, it is necessary to ensure that the non-woven fabric is tightly fitted to the base layer to avoid hollowing and delamination.

[0037] After the non-woven fabric is laid, a waterproof coating is applied to the top of the non-woven fabric layer 20 to form a coating layer 21. The waterproof coating should be applied evenly and uniformly, without any missing or excess coating. Remember that the coating thickness must meet the design requirements, usually not less than 1.5mm (polyurethane waterproof coating or acrylic waterproof coating can be used as the waterproof coating).

[0038] The groove 7 is opened on the inner side of the extension pipe 5, and the diameter of the groove 7 is larger than the diameter of the sewer pipe 3. The first moving ring and the second moving ring are mounted on the sewer pipe 3 and are located in the groove 7. The first moving ring and the second moving ring are made of rubber, which is used to improve the sealing performance between the sewer pipe 3 and prevent water flow on the floor layer 1 from seeping and leaking.

[0039] like Figure 3 As shown, the first dynamic ring includes a first clamping ring 8, a first embracing ring 9, and a first guide portion 10. The first embracing ring 9 is sleeved on the sewer pipe 3. The first clamping ring 8 is integrally connected to the bottom of the first embracing ring 9. The inner diameter of the first clamping ring 8 is larger than that of the first embracing ring 9, which facilitates the installation of the spring 17 and also serves as a limit for the internal spring 17. The first guide portion 10 is arranged obliquely on the inner side of the bottom of the first clamping ring 8 to guide the installed spring 17.

[0040] like Figure 3 As shown, the second dynamic ring includes a second clamping ring 11, a second embracing ring 12, and a second guide portion 13. The second embracing ring 12 is sleeved on the sewer pipe 3. The second clamping ring 11 is integrally connected to the top of the second embracing ring 12. The inner diameter of the second clamping ring 11 is larger than that of the second embracing ring 12, which facilitates the installation of the spring 17 while also limiting the internal spring 17. The second guide portion 13 is tilted on the inner side of the top of the second clamping ring 11 to guide the installed spring 17.

[0041] The spring 17 is mounted on the sewer pipe 3 and rests against the first holding ring 9 and the second holding ring 12 respectively. When the support plate 22 is installed, the support plate 22 will push the second dynamic ring upward. At this time, the spring 17 is deformed and thus pushes the first dynamic ring upward until the first dynamic ring rests against the upper surface of the groove 7 to complete the sealing work.

[0042] The inner sides of the first and second rings 9 and 12 are provided with sealing components, such as Figure 4As shown, the sealing assembly includes a sealing groove 14, a sealing ring 15, and an arcuate portion 16. The sealing groove 14 is provided on the inner side of the first and second holding rings 9 and 12, and the sealing ring 15 is disposed within the sealing groove 14. The arcuate portion 16 is provided on the inner side of the sealing ring 15. When the first and second moving rings are installed, the sealing ring 15 is squeezed and deformed and rests against the outer wall of the sewer pipe 3. At this time, the arcuate portion 16 serves to store water. In other words, if a small amount of water seepage and leakage occurs at the top of the floor slab 1, the seepage water will flow down along the outer wall of the sewer pipe 3 and be stored in the arcuate portion 16, preventing the seepage water from flowing along the sewer pipe 3 all the way to the bottom of the floor slab 1.

[0043] The support plate 22 is mounted on the sewer pipe 3 and fixed to the bottom of the floor layer 1. The fastening hole 23 passes through the support plate 22. The fixing hole 24 is opened at the bottom of the floor layer 1 and cooperates with the fastening hole 23. After the support plate 22 is installed, the expansion screw is used to complete the fixation of the support plate 22.

[0044] The first mounting groove 25 is opened at the top of the support plate 22, and the second mounting groove 26 is opened at the bottom of the first mounting groove 25 and passes through the support plate 22. The diameter of the first mounting groove 25 is larger than the diameter of the second mounting groove 26, so the diameters of the first mounting groove 25 and the second mounting groove 26 form a shoulder to fix the mounting block 27 and the sealing block 28.

[0045] A stopper 27 is disposed within the first mounting groove 25, and a sealing block 28 is integrally connected to the bottom of the stopper 27 and located within the second mounting groove 26. Both the stopper 27 and the sealing block 28 are made of rubber. When the support plate 22 is installed, the stopper 27 presses upward against the second movable ring. At this time, the spring 17 deforms, thereby pushing the first movable ring upward until the first movable ring presses against the upper surface of the groove 7.

[0046] When assembling the bathroom drain pipe opening and plugging device of the present invention, the sleeve 4 and the extension pipe 5 are put on the drain pipe 3, PVC glue is applied to the gap, the first dynamic ring and the second dynamic ring are put on the drain pipe 3 from the bottom, and then the support plate 22 is put under the drain pipe 3; the block 27 will push the second dynamic ring upward, and at this time the spring 17 will deform and push the first dynamic ring upward until the first dynamic ring rests on the upper surface of the groove 7; after the sealing work is completed, the support plate 22 is fixed to the bottom of the floor layer 1 using expansion bolts, and finally a step is built on the top of the sleeve 4.

[0047] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
