[0039] 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 understood as a limitation to the present invention.

[0040] A displaceable floor drain structure for a polyurethane waterproof bottom box, as shown in the attached Figure 1 , 3 , Figure 4, includes a pre-embedded cylinder 1, a supporting connecting piece 2, a displacement cylinder 3 and a waterproof cover plate 4. The waterproof cover plate 4 is installed on the top of the displacement cylinder 3. The displacement cylinder 3 is installed on the pre-embedded cylinder 1 through the supporting connecting piece 2. The displacement cylinder 3 is a movable part in the floor drain structure. A moving ring 311 is provided on the displacement cylinder 3. The displacement cylinder 3 is assembled on the supporting connecting piece 2 through the moving ring 311, and the relative position of the displacement cylinder 3 on the supporting connecting piece 2 can be adjusted through the moving ring 311. To facilitate the installation of the displacement cylinder 3, a limiting ring 211 is provided on the supporting connecting piece 2. A through hole is formed in the limiting ring 211. The aperture of the through hole is larger than the diameter of the displacement cylinder 3, and the area of the moving ring 311 is larger than the area of the through hole, so as to facilitate the adjustment of the position between the displacement cylinder 3 and the supporting connecting piece 2, enable the displacement cylinder 3 to quickly align with the drain pipe hole, improve the installation efficiency of the floor drain structure, and at the same time, the structure is simple, which can reduce costs and bring better economic benefits.

[0041] The pre-embedded cylinder 1 serves as the carrier of the entire floor drain structure, providing convenience for the subsequent installation of the floor drain. As shown in the attached Figure 2As shown in the figure, the embedded cylinder 1 includes a cylinder body 11 and a second connecting plate 12. The second connecting plate 12 is installed on the top of the cylinder body 11. The second connecting plate 12 is in the shape of a round-hole square plate. The square plate of the second connecting plate 12 is used to overlap the embedded box 7, which is convenient for installing the embedded cylinder 1 in the embedded box 7. The round hole of the second connecting plate 12 allows the supporting connecting piece 2 to enter, so that the supporting connecting piece 2 can be connected to the cylinder body 11 through the round hole. A connecting thread 111 is provided inside the cylinder body 11, and the connecting thread 111 is connected to the thread 221 on the outside of the supporting connecting piece 2.

[0042] As shown in the attached Figure 2 figure, a waterproof gasket 121 and a back plate 122 are provided on the second connecting plate 12. Both the waterproof gasket 121 and the back plate 122 are in the shape of a round-hole square plate, and their side lengths decrease in sequence. The waterproof gasket 121 is installed on the second connecting plate 12, and the back plate 122 is connected to the waterproof gasket 121. To facilitate the connection between the supporting connecting piece 2 and the embedded cylinder 1, the diameters of the round holes of the second connecting plate 12, the waterproof gasket 121, and the back plate 122 are larger than the diameter of the receiving cylinder 22 of the supporting connecting piece 2. A first step 12-1 is formed between the square plate of the waterproof backing plate 121 and the square plate of the second connecting plate 12, and a second step 12-2 is formed between the square plate of the back plate 122 and the square plate of the waterproof gasket 121. The first step 12-1 and the second step 12-2 are used to clamp the embedded box 7 to prevent water leakage and make the connection between the embedded cylinder 1 and the embedded box 7 more tight. The displaceable floor drain structure further includes a floor drain cover 8, and the floor drain cover 8 is installed on the back plate 122. A receiving groove 122-1 is provided inside the back plate 122, and the floor drain cover 8 is installed on the receiving groove 122-1.

[0043] The connection between the embedded cylinder 1 and the embedded box 7 is completed through the above steps. The embedded box 7 is connected through the second connecting plate 12, the first step 12-1, and the second step 12-2, and the floor drain cover 8 is installed through the receiving groove 122-1 on the back plate 122.

[0044] The supporting connecting piece 2 connected to the embedded cylinder 1 is as shown in the attached Figure 3 figure. The supporting connecting piece 2 includes a receiving bottom plate 21 and a receiving cylinder 22. The receiving bottom plate 21 is connected to the bottom of the receiving cylinder 22. A thread 221 is provided on the outside of the receiving cylinder 22, and the receiving cylinder 22 is connected to the embedded cylinder 1 through the thread 221. The height of the receiving cylinder 22 is less than the height of the cylinder body 11 of the embedded cylinder 1. The receiving bottom plate 21 is a round-hole plate, and the round hole of the receiving bottom plate 21 is used to receive the connecting cylinder 32 of the displacement cylinder 3, which is convenient for the connecting cylinder 32 to extend out of the receiving bottom plate 21 through the connecting hole 212.

[0045] As shown in the attached Figure 3 figure, the above-mentioned limiting ring 211 is a ring of raised blocks, which is specifically installed on the edge of the round hole of the receiving bottom plate 21, and forms a region for the displacement cylinder 3 to slide between it and the receiving bottom plate 21.

[0046] The connection between the supporting connector 2 and the embedded tube 1 is completed through the above steps, and the supporting connector 2 is screwed into the embedded tube 1 through the thread 221 on the receiving tube 22.

[0047] The displacement tube 3 connected to the supporting connector 2 is as shown in the attached Figure 4 As shown, the shift cylinder 3 includes a first connecting plate 31 and a connecting cylinder 32. The first connecting plate 31 is installed above the connecting cylinder 32. The connecting cylinder 32 passes into the circular hole of the receiving bottom plate 21 and is inserted into the position of the reserved drainage pipe. The first connecting plate 31 is a circular hole plate. The first connecting plate 31 is overlapped on the receiving bottom plate 21. The diameter of the circular plate of the first connecting plate 31 is larger than the diameter of the circular hole of the receiving bottom plate 21, so as to prevent the shift cylinder 3 from falling into the circular hole of the receiving bottom plate 21.

[0048] As attached Figure 4 As shown, the ultimate purpose of inserting the connecting tube 32 into the reserved drainage pipe is to play a drainage role. In order to make the connecting tube 32 have a better drainage effect, a sealing ring 321 is provided on the outside of the connecting tube 32. The material of the sealing ring 321 is usually rubber or silicone, because rubber and silicone have good sealing performance and corrosion resistance, which can effectively prevent leakage from the outside of the floor drain, and prevent water and dirt from penetrating into the floor drain pipe and the room. The above-mentioned moving ring 311 is specifically installed on the edge of the circular hole of the first connecting plate 31. The moving ring 311 is similar in shape to the limiting ring 211, which is a circle of raised blocks. The moving ring 311 not only plays the role of connecting the supporting connector 2, but also can drive the displacement tube 3 to move on the area formed by the supporting bottom plate 21 and the limiting ring 211. At the same time, when the displacement tube 3 moves on the supporting connector 2, in order to prevent the displacement tube 3 from falling from the circular hole of the supporting bottom plate 21 during the movement, the limiting ring 211 plays a role in limiting the movement of the displacement tube 3, preventing the displacement tube 3 from moving excessively and causing misalignment with the supporting connector 2.

[0049] As attached Figure 4 As shown, a first connecting groove 312 and a second connecting groove 313 connected to the bottom of the first connecting groove 312 are provided in the first connecting plate 31. The first connecting groove 312 is used to place a hidden floor drain cover 5. The method of installing the floor drain cover 8 by using the connecting groove can improve the safety of the floor drain structure and avoid people being tripped or stepped on the floor drain cover 8 when walking. At the same time, the design of the hidden floor drain cover 5 is more convenient to clean. The floor drain can be easily cleaned without removing the floor drain cover 8, which reduces the difficulty and time of cleaning. The floor drain core 6 is placed on the second connecting groove 313. The size and shape of the floor drain core 6 need to match the specifications and shape of the shift tube 3, otherwise it will cause problems such as unstable installation or water leakage. When using the floor drain core 6, it is necessary to clean and maintain it regularly to avoid excessive accumulation of debris and dirt in the core, which affects the filtering and drainage effects of the core.

[0050] The connection between the receiving connector, the hidden floor drain cover 5, the floor drain core 6 and the displacement tube 3 is completed through the above steps. The displacement tube 3 is connected to the supporting connector 2 through the movable ring 311. The displacement tube 3 moves in the area formed by the limiting ring 211 and the receiving base plate 21. The displacement tube 3 installs the hidden floor drain cover 5 through the first connecting groove 312 and installs the floor drain core 6 through the second connecting groove 313.

[0051] As attached Figure 5 As shown, the waterproof cover plate 4 is a circular plate, which covers the displacement tube 3 and plays a role in protecting the floor drain. The diameter of the waterproof cover plate 4 is larger than the diameter of the displacement tube 3 and smaller than the diameter of the supporting connector 2, which is convenient for the installation of the waterproof cover plate 4. The waterproof cover plate not only protects the floor drain, but also the water flowing through the waterproof cover plate needs to flow into the floor drain. Therefore, a drainage hole 41 is provided on the waterproof cover plate. The diameter of the drainage hole 41 is smaller than the inner diameter of the connecting tube 32 to prevent water from leaking or entering from the displacement tube 3 and ensure that the water flow can smoothly pass through the drainage hole 41 directly into the connecting tube 32 of the displacement tube 3. If the diameter of the drainage hole 41 is too large, water may penetrate into the interior of the displacement tube 3 from the drainage hole 41, affecting the waterproof performance and stability performance of the displacement tube 3.

[0052] In summary, a method for installing a displaceable floor drain structure for a polyurethane waterproof bottom box is as follows:

[0053] S1: The embedded tube 1 is installed in the embedded box 7, the second connecting plate 12 of the embedded tube 1 is overlapped on the embedded box 7, and the embedded box 7 is further clamped by the first clamping step 12-1 and the second clamping step 12-2 to prevent the embedded tube 1 and the embedded box 7 from loosening, so as to realize the connection between the embedded tube 1 and the embedded box 7;

[0054] S2: Screw the supporting connector 2 into the connecting thread 111 inside the embedded tube 1 through the outer thread 221 to achieve the connection between the supporting connector 2 and the embedded tube 1;

[0055] S3: Install the displacement cylinder 3 on the supporting connector 2. The displacement cylinder 3 moves on the supporting connector 2 through the moving ring 311. The limiting ring 211 on the supporting connector 2 limits the movement range of the displacement cylinder 3 to prevent the displacement cylinder 3 from moving beyond the limit. When the displacement cylinder 3 is adjusted to a suitable position, the connecting cylinder 32 is inserted into the drain pipe to realize the connection between the displacement cylinder 3 and the supporting connector 2, and at the same time, the connection between the displacement cylinder 3 and the drain pipe is realized;

[0056] S4: Install the floor drain core 6 on the second connection groove 313 of the displacement tube 3, and install the hidden floor drain cover 5 on the first connection groove 312 of the displacement tube 3;

[0057] S5: Install the waterproof cover plate 4 on the displacement tube 3 and the floor drain cover 8 on the back plate 122 of the embedded tube 1.

[0058] In summary, to complete the installation of the entire floor drain structure, the problem of hole alignment of the floor drain structure can be solved without adding an eccentric structure, which improves the installation efficiency of the floor drain and saves the installation cost.

[0059] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
