Abstract

A flange floor drain structure for a polyurethane bottom box that can absorb errors, as shown in the attached drawings. The flange floor drain structure includes a buried cylinder, a pressure equalizing drainage plate, and a displacement cylinder. The displacement cylinder is installed inside the buried cylinder. The pressure equalizing drainage plate is connected to the buried cylinder and installed above the displacement cylinder. The displacement cylinder includes a displacement cylinder flange, and the displacement cylinder flange overlaps on the buried cylinder. The pressure equalizing drainage plate is screwed into the buried cylinder by threads.

At the same time, the aperture of the buried cylinder is larger than the outer diameter of the displacement cylinder. By increasing the contact area between the displacement cylinder and the buried cylinder through the displacement cylinder flange, the installation error of the floor drain can be absorbed, the installation accuracy of the floor drain structure can be improved, and at the same time, the anti-leakage effect can be improved. Moreover, no eccentric treatment is required, saving costs.

[0001] The invention belongs to a different - layer drainage system of a polyurethane waterproof bottom box for an assembled integral bathroom, and particularly relates to a flange floor drain structure capable of absorbing errors for a polyurethane bottom box and an installation method thereof. Background Technique

[0002] With the popularization of assembled interior decoration, assembled integral bathrooms are increasingly favored by the market. As a waterproof bottom box applied to assembled integral bathrooms, the ceramic - tile integrated polyurethane waterproof bottom box has the advantages of controlling the slope of the bathroom floor and being convenient for installation. However, at the same time, in the case of different - layer drainage, due to construction errors in civil engineering, there will be a deviation between the position of the reserved drainage pipe on the project site and the position on the drawing, resulting in the inability to align the drainage pipe on the installation site with the reserved floor drain hole of the bottom box, and the bottom box has to be drilled on - site, thus greatly reducing the on - site installation efficiency.

[0003] For example, the eccentric floor drain with the authorized patent number CN201822088692.6 includes an eccentric floor drain main body, a floor drain cover, and an eccentric floor drain core; its characteristics are that the water inlet hole of the eccentric floor drain main body is eccentric, the floor drain core is also eccentric, the eccentric floor drain core and the water inlet hole of the eccentric floor drain main body can be matched with a sealing ring, and the eccentric floor drain core can rotate 360 degrees horizontally, so that the floor drain core is centered or deviated from the center. However, this patent still has the following disadvantages: (1) The above - mentioned floor drain needs to be eccentrically processed, resulting in a higher cost; (2) There is no obvious improvement in the alignment adjustment between the above - mentioned floor drain and the reserved pipeline. Summary of the Invention

[0004] Based on the deficiencies in the above - mentioned background technique, in view of the problems that the traditional floor drain structure cannot be aligned with the reserved floor drain hole, needs to be eccentrically processed, has low efficiency and high cost, etc., the invention provides a flange floor drain structure capable of absorbing errors for a polyurethane bottom box and an installation method thereof, ensuring that the floor drain structure can align with the reserved floor drain hole, improving the efficiency of installing the floor drain, and without the need for eccentricity, reducing the cost.

[0005] To achieve the above object, the invention is realized through the following technical solutions:

Detailed implementation manners

[0036] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the drawings in the following description are only a part of the embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0037] In the following description, terms such as "inner", "outer", "upper", "lower", "left", "right", etc. indicating orientation or position relationship are only for the convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0038] A flange floor drain structure for a polyurethane bottom box that can absorb errors, as shown in FIGS. Figure 1 , 3 , 4. The flange floor drain structure includes an embedded cylinder 1, a pressure equalizing and drainage plate 2, and a displacement cylinder 3. The displacement cylinder 3 is installed in the embedded cylinder 1. The pressure equalizing and drainage plate 2 is connected to the embedded cylinder 1 and installed above the displacement cylinder 3. The displacement cylinder 3 includes a displacement cylinder flange 31. The displacement cylinder flange 31 overlaps on the embedded cylinder 1. The pressure equalizing and drainage plate 2 is screwed into the embedded cylinder 1 through the thread 211. At the same time, since the pressure equalizing and drainage plate 2 is installed above the displacement cylinder flange 31 and contacts the displacement cylinder flange 31, the waterproof pad 34 below the displacement cylinder flange 31 can be pressed tightly, playing a waterproof role. At the same time, the aperture of the embedded cylinder 1 is larger than the outer diameter of the displacement cylinder 3. By increasing the contact area between the displacement cylinder 3 and the embedded cylinder 1 through the displacement cylinder flange 31, the installation error of the floor drain can be absorbed, the installation accuracy of the floor drain structure can be improved, the anti-leakage effect can also be improved, and no eccentric treatment is required, saving costs.

[0039] As shown in FIGS. Figure 1 , 2As shown, the embedded cylinder 1 is installed in the embedded box 7 which serves as the base of the floor drain structure. The embedded cylinder 1 is provided with a second connection groove 11 for receiving the displacement cylinder 3. The second connection groove 11 is arranged at the bottom of the embedded cylinder 1. There is a round hole at the bottom of the second connection groove 11 through which the drainage cylinder 32 of the displacement cylinder 3 passes. The second connection groove 11 is used to connect the displacement cylinder flange 31 of the displacement cylinder 3. The embedded cylinder 1 not only receives the displacement cylinder 3 but also can install the pressure equalizing and drainage plate 2. Therefore, the inner diameter of the embedded cylinder 1 is the same as the diameter of the pressure equalizing and drainage plate 2 and is larger than the diameter of the displacement cylinder flange 31, facilitating the installation of the displacement cylinder 3 into the embedded cylinder 1. Threaded connections 12 are provided inside the embedded cylinder 1, and corresponding threads 211 are provided on the outer side of the pressure equalizing and drainage plate 2. The pressure equalizing and drainage plate 2 is screwed into the embedded cylinder 1 to prevent loosening or water leakage between the pressure equalizing and drainage plate 2 and the embedded cylinder 1.

[0040] As shown in the attached Figure 1 、 2 figure, the embedded cylinder 1 is used to connect the displacement cylinder 3 and the floor drain cover 6. A step 13 and a connecting cylinder 14 are provided on the embedded cylinder 1. The step 13 is connected to the inner wall of the embedded cylinder 1 in a circular ring shape. The installation height of the step 13 is the same as or slightly greater than the thickness of the floor drain cover 6, making it flush with the ground or slightly lower than the ground, which is convenient for pedestrians to pass through and not easy to trip over. The connecting cylinder 14 is installed at the round hole at the bottom of the second connection groove 11. The drainage cylinder 32 of the displacement cylinder 3 is inserted into the connecting cylinder 14. At the same time, the outer wall of the connecting cylinder 14 is connected to the inner wall of the embedded box 7, which can increase the connection stability between the embedded cylinder 1 and the embedded box 7.

[0041] As shown in the attached Figure 1 、 4 figure, in this embodiment, the displacement cylinder 3 further includes a drainage cylinder 32 and a sealing ring 33. The drainage cylinder 32 is fixedly connected to the displacement cylinder flange 31. The sealing ring 33 is installed on the outer side of the drainage cylinder 32. The sealing ring 33 plays a sealing role to prevent water flow or sewage from overflowing. To achieve a better sealing effect, the sealing ring 33 needs to be made of a material with a certain strength and strong elasticity to ensure the structural stability. In the floor drain structure of this embodiment, the drainage cylinder 32 of the displacement cylinder 3 can drain the water in the floor drain structure. The drainage cylinder 32 is cylindrical and its diameter is slightly smaller than the diameter of the drainage pipe, facilitating the installation of the sealing ring 33 on the drainage cylinder 32 and then inserting it into the drainage pipe, so that the sealing ring 33 can exert a sealing and extrusion effect on the drainage pipe. At the same time, the drainage cylinder 32 and the sealing ring 33 are convenient for maintenance and replacement, ensuring the service life. The displacement cylinder 3 of this embodiment can effectively ensure the drainage effect and use safety of the floor drain, and is also convenient for maintenance and replacement, with a very good use effect.

[0042] As shown in the attached Figure 1 、 4As shown in the figure, a first connection groove 311 is provided on the shift cylinder flange 31. The first connection groove 311 is an annular structure and is fixedly connected to the inner edge of the circular hole of the shift cylinder flange 31. The floor drain core 4 is a hollow cylindrical structure. The outer diameter of the floor drain core 4 is adapted to the inner diameter of the first connection groove 311. The floor drain core 4 is clamped in the first connection groove 311 to ensure a stable and sealed connection between the floor drain core 4 and the first connection groove 311. The length of the floor drain core 4 needs to be determined according to the depth of the drainage pipe. The floor drain core 4 is used to introduce the water on the ground surface into the underground pipe. As the main body of the floor drain, the choice of its structure will directly affect the drainage effect of the floor drain.

[0043] As shown in the appendix Figure 4 As shown in the figure, a waterproof pad 34 is provided on the shift cylinder 3. The waterproof pad 34 is arranged at the lower end of the shift cylinder flange 31 and is fixedly connected to the shift cylinder flange 31. The waterproof pad 34 is usually made of rubber, fluororubber or other elastic materials. At the same time, the size and thickness of the waterproof pad 34 also need to conform to the specific dimensions of the shift cylinder flange 31 and the shift cylinder 3 to achieve a good sealing effect. Therefore, the diameter of the waterproof pad 34 is the same as that of the shift cylinder flange 32. The waterproof pad 34 can prevent water from penetrating into the structure of the shift cylinder 3 from the lower end of the shift cylinder flange 31, thus ensuring that the floor drain structure does not leak. The existence of the waterproof pad 34 can prevent the floor drain structure from leaking and having peculiar smells, increasing the comfort and convenience of use. At the same time, the usage situation of the waterproof pad 34 needs to be checked regularly, and it should be repaired or replaced when necessary.

[0044] As shown in the appendix Figure 1 As shown in the figure, the pressure equalizing and drainage plate 2 in the floor drain structure of the present invention can make the water flowing into the floor drain change direction and be blocked multiple times, reduce the water flow rate, weaken its kinetic energy, and make the water flow into the floor drain smoothly and slowly. This can reduce the impact of the water flow on the inner wall of the floor drain and extend the service life of the floor drain. At the same time, in this embodiment, the pressure equalizing and drainage plate 2 plays a fixing role on the shift cylinder 3. As shown in the appendix Figure 3 As shown in the figure, the pressure equalizing and drainage plate 2 includes a drainage round hole plate 21 and a connecting round hole plate 22. The connecting round hole plate 22 is fixedly connected to the inner side of the drainage round hole plate 21. Threads 211 are provided on the outer side of the drainage round hole plate 21. The pressure equalizing and drainage plate 2 is connected to the connecting thread 12 of the embedded cylinder 1 through the threads 211. The connection position of the pressure equalizing and drainage plate 2 and the embedded cylinder 1 touches the shift cylinder 3, which is convenient for connecting the pressure equalizing and drainage plate 2 to the shift cylinder 3. At this time, the pressure equalizing and drainage plate 2 plays a fixing role on the shift cylinder 3. During the process of the pressure equalizing and drainage plate 2 twisting on the thread 12 of the embedded cylinder 1, the waterproof pad 34 of the shift cylinder 3 is squeezed, increasing the stability of the connection between the shift cylinder 3 and the embedded cylinder 1 and ensuring the safety of use. A floor drain filter screen 5 is installed on the connecting round hole plate 22, which can prevent sundries or dirt from entering the drainage system, thus ensuring the drainage effect and use safety.

[0045] As shown in the appendix Figure 3As shown in the figure, the drainage circular hole plate 21 of this embodiment is provided with a drainage groove 212. The function of the drainage groove 212 is to guide the water or liquid on the ground to the floor drain filter screen 5. In the floor drain structure, the cooperation between the drainage groove 212 and the floor drain filter screen 5 is conducive to improving the drainage quality. The outer edge of the drainage groove 212 is connected to the outer edge of the drainage circular hole plate 21, and the inner edge is connected to the outer edge of the floor drain filter screen 5 on the connecting circular hole plate 22. The drainage groove 212 is tightly connected to the outer edge of the floor drain filter screen to prevent water flow or sewage from leaking out between the two. The drainage groove 212 of the drainage circular hole plate 21 can drain water to the floor drain filter screen 5 of the connecting circular hole plate 22, thus ensuring the drainage effect and use safety.
