Description

Technical Field

[0001] The utility model belongs to the technical field of toilet installation fittings, and particularly relates to a split toilet flange sealing ring. Background Art

[0002] During the installation of a toilet, the toilet outlet at the bottom of the toilet is connected to the drainage pipe through a flange, which can prevent the overflow of odor and sewage.

[0003] A patent with the publication number of CN220037728U discloses a connecting pipe for a toilet outlet, which includes a pipe body. The pipe body includes a connecting part for connecting to the bottom of the toilet and a plugging part for inserting into the drainage pipe. A sealing ring for circumferential sealing with the drainage pipe is arranged on the outer side of the plugging part. It is characterized in that a connecting surface for placing glue is arranged at the upper end of the connecting part, and a constricted section inclined inward is arranged on the connecting part; a limiting boss is arranged on the outer side of the plugging part, the sealing ring is tightly fitted with the plugging part, and the upper end of the sealing ring abuts against the limiting boss.

[0004] In the above prior art, sealing is achieved by arranging a sealing ring between the drainage pipe and the plugging part. However, for some drainage pipes, in order to increase strength or for some other reasons, threads or ribs are arranged on the inner wall of the pipe, that is, the inner wall of the drainage pipe is not smooth, which also makes it difficult to achieve effective and stable sealing between the sealing ring and the drainage pipe. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a split toilet flange sealing ring for the above problems existing in the prior art.

[0006] To achieve the purpose of the innovation, the utility model can be realized by the following technical solutions:

[0007] A split toilet flange sealing ring is installed between the toilet and the drainage pipe, and includes a toilet connecting body for sealing connection with the position of the toilet outlet at the bottom of the toilet, and a pipe connecting body for sealing connection with the drainage pipe. The toilet connecting body is inserted into the pipe connecting body, and a circumferential sealing structure is arranged between the toilet connecting body and the pipe connecting body.

[0008] The toilet connector is used for sealing connection with the toilet outlet at the bottom of the toilet, so as to achieve the sealing of the bottom of the toilet; the drainage pipe is sealed connected with the pipe connector, so as to achieve the sealing of the drainage pipe; after the toilet connector is inserted into the pipe connector, the circumferential sealing structure is used to achieve the sealing between the toilet connector and the pipe connector, and thus the sealing connection of the whole link from the toilet outlet - toilet connector - pipe connector - drainage pipe is realized. Therefore, it can effectively prevent the odor in the drainage pipe from overflowing into the bathroom and prevent the water flow from overflowing from the drainage pipe to the ground when flushing. In addition, since the toilet connector and the pipe connector are inserted and connected, during installation, first seal the connection between the pipe connector and the drainage pipe, then turn the toilet over, seal the connection between the toilet connector and the toilet outlet, and finally directly lift the toilet up and insert the toilet connector directly into the pipe connector to complete the installation. This installation method does not need to consider the height difference between the toilet outlet and the periphery of the toilet, because after the toilet connector is inserted into the pipe connector, the insertion depth of the toilet connector into the pipe connector can be adjusted adaptively according to the height difference between the toilet outlet and the periphery of the toilet. That is, after the toilet stands on the ground, if the height difference between the periphery of the toilet and the toilet outlet is large, the insertion depth of the toilet connector into the pipe connector is relatively shallow; if the height difference between the periphery of the toilet and the toilet outlet is small, the insertion depth of the toilet connector into the pipe connector is relatively deep. Since the circumferential sealing structure is used to achieve the seal between the toilet connector and the pipe connector, the change of its insertion depth will not affect the sealing effect. At the same time, the advantage of the circumferential sealing structure is that if the angle needs to be adjusted after the toilet is installed, rotating the toilet will not cause the seal to fail.

[0009] In the above-mentioned split toilet flange sealing ring, the toilet connector includes a toilet connection part and a plug-in part. The toilet connection part is provided with a toilet connection surface for applying glue. The toilet connection surface can be sealed and connected to the toilet outlet through glue. The plug-in part is in a straight cylinder shape for plugging into the pipe connector.

[0010] The toilet connection part is provided with a toilet connection surface, which is used to specifically connect with the toilet water outlet at the bottom of the toilet. Specifically, it can be connected with the end face of the toilet water outlet, or it can be connected with the bottom of the toilet outside the toilet water outlet. The sealing is achieved by setting a colloid between the toilet water outlet and the toilet connection surface. On the one hand, the colloid can change adaptively with the distance between the toilet water outlet and the toilet connection surface, and can adapt to toilet water outlets of different heights within a certain range. On the other hand, the colloid forms a closed-loop sealing bond between the toilet connection surface and the port of the toilet water outlet or the bottom of the toilet outside the toilet water outlet to ensure the sealing effect. The bonding and fixing method can avoid the circumferential sealing connection between the two and the disconnection, improve the stability of the seal, and at the same time, the fixation and sealing are achieved by the cement to facilitate assembly. The plug-in part is used to position the toilet connector, and also provides conditions for setting a sealing structure between the inner wall of the pipe connector. The colloid can be mud-like clay, a water-tight and air-tight elastic cushion layer or some other feasible water-tight and air-tight structures. The elastic cushion layer can also be made more viscous, but clay is the preferred colloid.

[0011] As an optimization, the toilet connecting part and the plug-in part are connected by a reduced diameter part which is larger on the outside and smaller on the inside. The reduced diameter part is sleeved on the toilet water outlet and can adapt to toilet water outlets of different heights and outer diameters to improve compatibility. Moreover, colloid can also be applied on the inner arc surface of the reduced diameter part for gluing and connecting with the lower end of the toilet water storage port to further enhance the sealing effect.

[0012] Furthermore, the toilet connection part is provided with a track groove for breaking, and the track groove forms a breaking part for breaking along the toilet connection surface and the reduced diameter part, and the reduced diameter part outside the breaking part is provided with an auxiliary adhesive surface extending radially outward, and a clearance gap is formed when the breaking part is broken. The colloid can be arranged on the auxiliary adhesive surface and the clearance gap to form a closed loop, which is particularly suitable for toilets with ridge-like protrusions on the side of the toilet water outlet. The clearance gap is used to make way for the ridge-like protrusions. At the same time, the closed loop of colloid is connected with the plane and ridge-like protrusions outside the toilet water outlet at the bottom of the toilet to ensure sealing and improve compatibility. The clearance gap and the auxiliary adhesive surface are straight or arc-shaped.

[0013] In the above-mentioned split-type toilet flange sealing ring, the circumferential sealing structure includes a sealing ring arranged on the outside of the plug-in portion, and the sealing ring is snap-fitted or tightly mounted on the outside of the toilet connecting body.

[0014] The sealing ring is arranged inside the toilet connector and is pressed tightly between the toilet connector and the insertion part. The inner and outer sides of the sealing ring are in close contact with the corresponding side walls, ensuring a good circumferential sealing effect. Further, two circumferentially extending and radially protruding first ribs are provided on the outer side of the insertion part, and the sealing ring is limited and sleeved in the first installation groove between the two first ribs, which is convenient for disassembly and assembly and has a stable limiting effect. In order to simplify processing, only one first rib can also be provided. The sealing ring is sleeved on the insertion part from below, and the upper end abuts against the first rib to achieve axial limitation.

[0015] In the above-mentioned split toilet flange sealing ring, the circumferential sealing structure includes a sealing ring arranged inside the pipe connector. The sealing ring is clamped on the inner wall of the pipe connector, and when the toilet connector is inserted into the pipe connector, the inner wall of the sealing ring is in close contact with the outer side of the pipe connector to achieve sealing.

[0016] As another solution, the sealing ring can also be arranged on the inner side wall of the pipe connector. Similarly, an effective circumferential seal is formed between the inner side wall of the pipe connector and the outer side wall of the toilet connector. The installation of the sealing ring can also be realized by two circumferentially extending and radially protruding first ribs arranged on the inner side wall of the pipe connector, which is convenient for disassembly and assembly and has a good limiting effect. Similarly, in order to simplify processing, only one first rib can also be provided. The sealing ring is tightly and fittingly clamped into the pipe connector from below, and the upper end abuts against the first rib to achieve axial limitation.

[0017] In the above-mentioned split toilet flange sealing ring, the sealing ring includes a main body made of an elastic material. The inner wall of the main body is in a straight cylindrical shape, the outer wall of the main body is inclined, the cross-section of the main body has a hollowed-out hollow part, the non-hollowed part of the main body forms a sealing part, the small end of the main body forms a first guiding part, and the large end of the main body forms a pressing part.

[0018] The cross-section of the main body is an H shape with one side inclined outwards. When the toilet connector is inserted into the pipe connector, the first guiding part at the small end of the main body facilitates the easier insertion of the toilet connector into the pipe connector. After the toilet connector is inserted into the pipe connector, since the main body is inclined outwards, after being squeezed by the inner wall of the pipe connector, the pressing part contracts inwards, so that the outer side of the pressing part fits with the inner side of the pipe connector to form a seal, and the outer side of the sealing part is also squeezed by the inner side of the pipe connector to form a seal, thereby realizing surface sealing. The sealing area of surface sealing is much larger than the line sealing of ordinary sheet-shaped sealing rings, so the sealing effect between the toilet connector and the pipe connector is ensured.

[0019] In the above-mentioned split toilet flange seal ring, the pipeline connecting body includes a pipe body for inserting into the drainage pipeline and a hanging platform arranged at the end of the pipe body. The side of the hanging platform close to the pipe body is a pipeline connecting surface for applying glue, and the pipeline connecting surface can be hermetically connected to the end of the drainage pipeline through a colloid.

[0020] Since there is an elastic colloid on the toilet connecting surface, during installation, before inserting the pipe body into the drainage pipeline, the position can be aligned first. If offset is needed, after offsetting to the required position, the pipeline connecting body can be lowered, and the drainage pipeline and the pipeline connecting surface can be hermetically connected by using the colloid. During actual installation, the drainage pipeline can be directly embedded into the colloid, so as to realize the seal between the drainage pipeline and the pipeline connecting body. This solution can not only achieve the end face seal of the drainage pipeline, but also, if the width of the hanging platform is large enough, realize the seal between the colloid on the pipeline connecting surface and the bathroom floor tile, thus achieving a double-sealing effect. In addition, during installation, first connect the pipeline connecting body with the drainage pipeline, and the installation is light and convenient, without the need to lift the entire toilet to align it with the drainage pipeline. The colloid can adopt mud-like clay, an impermeable and airtight elastic cushion layer or some other feasible impermeable and airtight structures. The elastic cushion layer can also be increased in viscosity, and the colloid is preferably clay.

[0021] In the above-mentioned split toilet flange seal ring, a second guiding part is arranged at the connection between the pipe body and the hanging platform.

[0022] Setting the second guiding part facilitates guiding when the toilet connecting body is inserted into the pipeline connecting body, improving the installation convenience. The second guiding part is arranged at the connection between the inner side of the pipe body and the hanging platform, preferably in the form of a chamfer.

[0023] In the above-mentioned split toilet flange seal ring, the pipeline connecting body includes a pipe body for inserting into the drainage pipeline and a hanging platform arranged at the end of the pipe body. A pipeline seal ring is arranged on the outer side of the pipe body. The pipeline seal ring is connected to the outer side of the pipe body by snap connection or tight fit, and when the pipe body is inserted into the drainage pipeline, the outer side of the pipeline seal ring closely adheres to the drainage pipeline to achieve a seal.

[0024] As another solution, the circumferential seal between the pipeline connecting body and the drainage pipeline can also be achieved between their opposite side walls. The elastic pipeline seal ring is pressed between the outer side of the pipeline connecting body and the inner side wall of the drainage pipeline to achieve effective sealing. Although this sealing method is not conducive to radial adjustment, it is convenient for disassembly and assembly. Preferably, in order to limit the installation of the pipeline seal ring, two circumferentially extending and radially protruding second ribs are arranged on the outer side of the pipe body, and the pipeline seal ring is clamped and limited in the second groove between the two second ribs to achieve flexible limit installation.

[0025] In the above-mentioned split toilet flange seal ring, a plurality of clamping holes are arranged on the hanging platform.

[0026] The card hole can be an opening hole provided on the outer side of the hanging platform, or a through hole provided in the middle of the hanging platform. Its function is to fix the hanging platform to the ground through structures such as bolts or screws, improving the installation firmness of the pipeline connector on the bottom surface.

[0027] In the above-mentioned split toilet flange sealing ring, the toilet connection surface is provided with a colloidal fitting part with unevenness.

[0028] The colloidal fitting part is in a rough state with unevenness, which helps the adhesion of the colloid, avoids the slipping of the colloid during gluing, facilitates installation, and at the same time makes the colloid bite tighter and the connection effect better.

[0029] Compared with the prior art, the utility model mainly has the following advantages:

[0030] 1. The toilet connector realizes the seal with the bottom of the toilet, the drainage pipeline realizes the seal with the drainage pipeline, and the circumferential seal structure realizes the seal between the toilet connector and the pipeline connector. Thus, the whole link from the toilet outlet - toilet connector - pipeline connector - drainage pipeline is sealed and connected, effectively preventing the odor in the drainage pipeline from overflowing into the bathroom and preventing the water flow from overflowing from the drainage pipeline to the ground during flushing.

[0031] 2. The toilet connector and the pipeline connector are inserted and connected. There is no need to consider the height difference between the toilet outlet and the periphery of the toilet. The change of the insertion depth of the toilet connector will not affect the sealing effect. At the same time, the circumferential seal structure makes it so that when the angle needs to be adjusted after the toilet is installed, rotating the toilet will not cause the seal to fail.

[0032] 3. The seal between the toilet outlet and the toilet connection surface is realized by setting a colloid, which can adapt to toilet outlets of different heights, improving the practicability. The colloid has adaptive deformation and bonds the toilet outlet and the toilet connection surface, which also ensures a good and stable sealing effect and is convenient for assembly at the same time.

[0033] 4. The cross-section of the main body is an H shape with one side inclined outward. When the toilet connector is inserted into the pipeline connector, the first guiding part facilitates the toilet connector to be more easily inserted into the pipeline connector. After being extruded by the inner wall of the pipeline connector, the extrusion part contracts inward, making the outer side of the extrusion part fit with the inner side of the pipeline connector to form a seal, and the outer side of the seal part is also extruded with the inner side of the pipeline connector to form a seal, thereby realizing surface sealing and ensuring the sealing effect between the toilet connector and the pipeline connector.

[0034] 5. During installation, before inserting the pipe body into the drainage pipe, the position can be aligned first. If offset is needed, the pipe connection body can be lowered after offsetting to the desired position for easy adjustment. The drainage pipe and the pipe connection surface are hermetically connected using a colloid. The drainage pipe is embedded in the colloid, which can achieve the end face sealing of the drainage pipe. If the width of the hanging platform is large enough, it can also achieve the sealing between the colloid and the bathroom floor tile, thus achieving a double-sealing effect.

[0035] 6. The second guiding part is provided to facilitate guiding when the toilet connection body is inserted into the pipe connection body, improving the installation convenience.

[0036] 7. The clamping holes can be used to fix the hanging platform to the ground through structures such as bolts or screws, enhancing the installation firmness of the pipe connection body on the bottom surface.

[0037] 8. The colloid fitting part is in an uneven and rough state, which helps the attachment of the colloid, avoids the slipping of the colloid during gluing, facilitates installation, and at the same time makes the colloid bite tighter, resulting in a better connection effect.

Specific implementation mode

[0048] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0049] Embodiment 1

[0050] Specific embodiments are as Figures 1-6 shown. This split-type toilet flange sealing ring is installed between the toilet 1 and the drainage pipe 2, and includes a toilet connector 3 for sealing connection with the position of the toilet water outlet 11 at the bottom of the toilet 1, and a pipe connector 4 for sealing connection with the drainage pipe 2. The toilet connector 3 is inserted into the pipe connector 4, and a circumferential sealing structure 5 is provided between the toilet connector 3 and the pipe connector 4.

[0051] Specifically, the toilet connector 3 is used to be hermetically connected to the toilet outlet 11 at the bottom of the toilet 1, so as to achieve the sealing at the bottom of the toilet 1; the drain pipe 2 is hermetically connected to the pipe connector 4, so as to achieve the sealing of the drain pipe 2; after the toilet connector 3 is inserted into the pipe connector 4, the circumferential sealing structure 5 is used to achieve the sealing between the toilet connector 3 and the pipe connector 4. Since then, the entire link from the toilet outlet 11 - toilet connector 3 - pipe connector 4 - drain pipe 2 is hermetically connected. Therefore, it can effectively prevent the odor in the drain pipe 2 from overflowing into the bathroom and prevent the water flow from overflowing from the drain pipe 2 to the ground during flushing. In addition, since the toilet connector 3 and the pipe connector 4 are connected by insertion, during installation, first hermetically connect the pipe connector 4 to the drain pipe 2, then turn the toilet 1 over, hermetically connect the toilet connector 3 to the toilet outlet 11, and finally directly lift the toilet 1 up and insert the toilet connector 3 directly into the pipe connector 4 to complete the installation. This installation method does not need to consider the height difference between the toilet outlet 11 and the outside of the toilet 1, because after the toilet connector 3 is inserted into the pipe connector 4, the insertion depth of the toilet connector 3 into the pipe connector 4 can be adaptively adjusted according to the height difference between the toilet outlet 11 and the outside of the toilet 1. That is, after the toilet 1 is standing on the ground, if the height difference between the outside of the toilet 1 and the toilet outlet 11 is large, the insertion depth of the toilet connector 3 into the pipe connector 4 is shallower; if the height difference between the outside of the toilet 1 and the toilet outlet 11 is small, the insertion depth of the toilet connector 3 into the pipe connector 4 is deeper. Since the toilet connector 3 and the pipe connector 4 use the circumferential sealing structure 5 to achieve sealing, the change of its insertion depth will not affect the sealing effect. At the same time, the advantage brought by the circumferential sealing structure 5 is that if the angle of the toilet 1 needs to be adjusted after the installation of the toilet 1, rotating the toilet 1 will not cause the sealing to fail.

[0052] As Figure 2 、 5 shown, the toilet connector 3 includes a toilet connection part 31 and a plug-in part 32. The toilet connection part 31 is provided with a toilet connection surface 33 for applying glue. The toilet connection surface 33 can be hermetically connected to the toilet outlet 11 through glue. The plug-in part 32 is in a straight cylinder shape and is used for plugging into the pipe connector 4.

[0053] Specifically, a toilet connection surface 33 is provided on the toilet connection part 31. This surface is used for specifically docking with the toilet outlet 11 at the bottom of the toilet 1. Specifically, it can be docked and connected with the end face of the toilet outlet 11, or it can be docked and connected with the bottom of the toilet 1 outside the toilet outlet 11. A colloid is provided between the toilet outlet 11 and the toilet connection surface 33 to achieve sealing. The colloid specifically uses mud-like clay. On the one hand, the colloid can adaptively change with the distance between the toilet outlet 11 and the toilet connection surface 33, and can adapt to toilet outlets 11 of different heights within a certain range. On the other hand, the colloid forms a closed-loop sealed bond between the toilet connection surface 33 and the port of the toilet outlet 11 or the bottom of the toilet 1 outside the toilet outlet 11, ensuring the sealing effect. Moreover, the bonding and fixing method can prevent the circumferential sealed connection between the two from disconnecting, improving the stability of the seal. At the same time, using clay to achieve fixation and sealing facilitates assembly. The insertion part 32 is used to position the toilet connection body 3 and also provides conditions for setting a sealing structure between the inner side wall of the toilet connection body 3 and the pipe connection body 4.

[0054] In this embodiment, the circumferential sealing structure 5 includes a sealing ring 51 provided outside the insertion part 32. The sealing ring 51 is tightly fitted and installed on the outside of the toilet connection body 3. The sealing ring 51 includes a main body 52 made of an elastic material. The inner wall of the main body 52 is in a straight cylinder shape, the outer wall of the main body 52 is inclined, the cross-section of the main body 52 has a hollowed-out hollow part 53, the non-hollowed part of the main body 52 forms a sealing part 54, the small end of the main body 52 forms a first guiding part 55, and the large end of the main body 52 forms a pressing part 56.

[0055] Specifically, the sealing ring 51 is provided inside the toilet connection body 3 and is pressed tightly between the toilet connection body 3 and the insertion part 32. The inner and outer sides of the sealing ring 51 and the corresponding side walls are in close contact, ensuring a good circumferential sealing effect. Further, two circumferentially extending and radially protruding first ribs 57 are provided outside the insertion part 32. The sealing ring 51 is limited and sleeved in the first installation groove between the two first ribs 57, which is convenient for disassembly and assembly and has a stable limiting effect. The cross-section of the main body 52 is an H shape with one side inclined outward. When the toilet connection body 3 is inserted into the pipe connection body 4, the first guiding part 55 at the small end of the main body 52 facilitates the toilet connection body 3 to be more easily inserted into the pipe connection body 4. After the toilet connection body 3 is inserted into the pipe connection body 4, since the main body 52 is inclined outward, after being squeezed by the inner wall of the pipe connection body 4, the pressing part 56 contracts inward, so that the outer side of the pressing part 56 fits with the inner side of the pipe connection body 4 to form a seal, and the outer side of the sealing part 54 is also squeezed by the inner side of the pipe connection body 4 to form a seal, thereby realizing surface sealing. The sealing area of surface sealing is much larger than the line sealing of an ordinary sheet-shaped sealing ring 51, so the sealing effect between the toilet connection body 3 and the pipe connection body 4 is ensured.

[0056] Such as Figure 2 、 6As shown, the pipe connector 4 includes a pipe body 41 for inserting into the drainage pipe 2 and a hanging platform 42 provided at the end of the pipe body 41. The side of the hanging platform 42 close to the pipe body 41 is a pipe connection surface 43 for applying glue, and the pipe connection surface 43 can be hermetically connected to the end of the drainage pipe 2 through a colloid. A second guiding portion 44 is provided at the connection between the pipe body 41 and the hanging platform 42.

[0057] Specifically, since the toilet connection surface 33 is provided with an elastic colloid, during installation, before the pipe body 41 is inserted into the drainage pipe 2, the position can be aligned first. If offset is required, after offsetting to the required position, the pipe connector 4 can be lowered, and the drainage pipe 2 and the pipe connection surface 43 can be hermetically connected by using the colloid. During actual installation, the drainage pipe 2 can be directly embedded in the colloid, thereby realizing the sealing between the drainage pipe 2 and the pipe connector 4. This solution can not only achieve the end surface sealing of the drainage pipe 2, but also, if the width of the hanging platform 42 is large enough, achieve the sealing between the colloid on the pipe connection surface 43 and the bathroom floor tile, thereby realizing a double sealing effect. In addition, during installation, first connect the pipe connector 4 to the drainage pipe 2, which is easy to install and does not require the entire toilet 1 to be lifted up to align with the drainage pipe 2. The colloid is a mud-like clay. The second guiding portion 44 is provided to facilitate guiding when the toilet connector 3 is inserted into the pipe connector 4, improving the installation convenience. The second guiding portion 44 is provided at the connection between the inner side of the pipe body 41 and the hanging platform 42, specifically in the form of a rounded corner.

[0058] As an optimization of this embodiment, several through-hole type clamping holes 47 are provided in the middle of the hanging platform 42, and the hanging platform 42 can be fixed to the ground by bolts, improving the installation firmness of the pipe connector 4 on the bottom surface.

[0059] As an optimization, the toilet connection surface 33 is provided with an uneven colloid fitting portion 39. The colloid fitting portion 39 increases the roughness, which helps the attachment of the colloid, avoids the slipping of the colloid during glue application, facilitates installation, and at the same time makes the bite of the colloid tighter and the connection effect better.

[0060] As a further optimization of this embodiment, the toilet connection part 31 and the plug-in part 32 are connected by a reduced diameter part 34 with a larger outer part and a smaller inner part. The reduced diameter part 34 is sleeved on the toilet water outlet 11 and can adapt to toilet water outlets 11 of different heights and outer diameters to improve compatibility. The toilet connection part 31 is provided with a track groove 38 for breaking. The track groove 38 forms a breaking part 35 for breaking along the toilet connection surface 33 and the reduced diameter part 34. The reduced diameter part 34 outside the breaking part 35 is provided with a planar auxiliary gluing surface 36 extending radially outward. When the breaking part 35 is broken, a clearance gap 37 is formed. The colloid can be arranged on the auxiliary upper glue surface 36 and the clearance gap 37 to form a closed loop, which is particularly suitable for the toilet 1 with a ridge-like protrusion on the side of the toilet water outlet 11. The clearance gap 37 is used to make way for the ridge-like protrusion. At the same time, the closed-loop colloid is connected to the plane and ridge-like protrusion on the outside of the toilet water outlet 11 at the bottom of the toilet 1 to ensure sealing and improve compatibility.

[0061] Specific working principle: During assembly, apply colloid 6 on the pipe connection surface 43, insert the pipe connector 4 into the drainage pipe 2, and adhere the colloid 6 to the end of the drainage pipe 2 to achieve the sealing of the pipe connector 4 and the drainage pipe 2; in addition, apply colloid 6 on the toilet connection surface 33, put the toilet connector 3 on the toilet water outlet 11 of the toilet 1, and adhere the colloid 6 to the bottom of the toilet 1, so that the toilet connector 3 is sleeved on the outside of the toilet water outlet 11. After that, move the toilet 1 to the drainage pipe 2, align the toilet connector 3 with the pipe connector 4, put down the toilet 1, and the toilet connector 3 is automatically plugged into the pipe connector 4, and the installation is completed.

[0062] After the pipe connector 4 is inserted into the drainage pipe 2, it can also be displaced first, and its installation angle and orientation can be adjusted. After it is adjusted into place, it is pressed hard to make the colloid 6 fit the end of the drainage pipe 2 to achieve sealing.

[0063] Example 2

[0064] The specific working principle of this embodiment is basically the same as that of Embodiment 1, except that the difference lies in the circumferential sealing structure 5 .

[0065] Specific implementation examples Figure 7 As shown, the circumferential sealing structure 5 includes a sealing ring 51 arranged on the inner side of the pipe connector 4. The sealing ring 51 is clamped on the inner wall of the pipe connector 4, and when the toilet connector 3 is inserted into the pipe connector 4, the inner wall of the sealing ring 51 is tightly against the outer side of the pipe connector 4 to achieve sealing.

[0066] In this embodiment, the sealing ring 51 is arranged on the inner side wall of the pipe connector 4, forming an effective circumferential seal between the inner side wall of the pipe connector 4 and the outer side wall of the toilet connector 3. There are two first ribs 57 that extend circumferentially and protrude radially on the inner side wall of the pipe connector 4, and the sealing ring 51 is sleeved in the first installation groove between the two first ribs 57, which is convenient for disassembly and assembly and has a good limiting effect.

[0067] Embodiment 3

[0068] The specific working principle of this embodiment is basically the same as that of Embodiment 1, and the difference lies in the pipe connector 4.

[0069] Specific implementation example is as Figure 8 shown. The pipe connector 4 includes a pipe body 41 for inserting into the drainage pipe 2 and a hanging platform 42 arranged at the end of the pipe body 41. A pipe sealing ring 45 is arranged on the outer side of the pipe body 41. The pipe sealing ring 45 is connected to the outer side of the pipe body 41 by snap connection or tight fit, and when the pipe body 41 is inserted into the drainage pipe 2, the outer side of the pipe sealing ring 45 closely adheres to the drainage pipe 2 to achieve sealing.

[0070] In this embodiment, the circumferential seal between the pipe connector 4 and the drainage pipe 2 can also be achieved between their opposite side walls. The elastic pipe sealing ring 45 is pressed between the outer side of the pipe connector 4 and the inner side wall of the drainage pipe 2 to achieve effective sealing. Although this sealing method is not conducive to radial adjustment, it is convenient for disassembly and assembly. In order to limit the installation of the pipe sealing ring 45, two second ribs 46 that extend circumferentially and protrude radially are arranged on the outer side of the pipe body 41, and the pipe sealing ring 45 is sleeved and limited in the second installation groove between the two second ribs 46. Further, the pipe sealing ring 45 also adopts a structure similar to that of the sealing ring 51.

[0071] Embodiment 4

[0072] The specific working principle of this embodiment is basically the same as that of Embodiment 1, and the difference lies in the sealing structure between the drainage pipe 2 and the pipe connector 4.

[0073] Specific implementation example is as Figure 9 shown. A pipe sealing ring 45 is arranged between the drainage pipe 2 and the pipe connector 4. The pipe sealing ring 45 is tightly sleeved on the pipe body 41. The port of the drainage pipe 2 is lower than the ground, and no colloid 6 is arranged between the hanging platform 42 and the drainage pipe 2.

[0074] Specifically, this embodiment is particularly applicable to the application scenario where the drainage pipe 2 is lower than the ground, solving the problem that it is difficult to apply colloid between the hanging platform 42 and the upper end face of the drainage pipe 2 due to the low upper port of the drainage pipe 2. The pipe sealing ring 45 is in close contact with the inner side wall of the drainage pipe 2 and the outer side wall of the pipe body 41 respectively to form an effective circumferential seal. Moreover, the pipe sealing ring 45 is directly tightly fitted on the pipe body 41 in a sleeved manner, which is convenient for disassembly and assembly. As an optimization, the cross section of the pipe sealing ring 45 in this embodiment is comb-shaped and has three annular sealing ring layers, further ensuring the sealing effect.

[0075] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
