[0051] Embodiment 1

[0052] In order to solve the problem of poor sealing between the toilet body and the sewage pipe in the toilet device in the prior art, this embodiment provides a sealing tube, which is arranged between the sewage pipe and the toilet body, and the sewage pipe and the toilet body are sealed and connected through the sealing tube.

[0053] A sealed tube, see Figures 1 to 4 The sealing tube includes an axially extending tube section 1 and a sealing tube section 2, a first annular rib 3 and a second annular rib 4 arranged at one end of the tube section 1. The sealing tube section 2 has a circumferential flange 21 extending radially toward the side away from the axis. The first annular rib 3 is arranged on the outer surface of the tube section 1, and the second annular rib 4 is arranged on the circumferential flange 21. Along the axial direction of the tube section 1, the second annular rib 4 has at least a first part 41 and a second part 42 arranged on both sides of the circumferential flange 21.

[0054] Specifically, the sealing tube of this embodiment adopts a structure in which the first annular rib 3, the circumferential flange 21 and the second annular rib 4 cooperate to form a first layer of sealing at the first annular rib 3 and a second layer of sealing at the circumferential flange 21. The second annular rib 4 is provided to improve the stability of the installation of the sealing tube, and further, the sealing tube structure of this embodiment is provided between the tubes, which is conducive to increasing the sealing effect. The double-layer sealing structure is used to improve the sealing effect.

[0055] Among them, a first sealing surface can be formed on the outer peripheral surface of the first annular rib 3 to achieve sealing of the radially extending structure, and the circumferential flange 21 provides two second sealing surfaces arranged axially opposite to each other to achieve sealing of the axially extending structure.

[0056] During the installation process of the sewage pipe 5 and the toilet body, the sealing tube as an intermediate piece can play a role in strengthening the sealing and connection strength, increasing the sealing of the sewage pipe 5 and the toilet body, and reducing the occurrence of leakage.

[0057] Furthermore, in this embodiment, the first annular rib 3 is used to abut against the inner surface of the sewage pipe 5, thereby reducing the possibility of liquid passing through between the sewage pipe 5 and the sealing pipe, thereby achieving a sealing effect.

[0058] Furthermore, the first part 41 and the second part 42 of the second annular rib 4 play a connecting role. When the sewage pipe 5 and the toilet body are installed, the second part 42 can be inserted into the second limiting groove 64 of the installation cover 6, and the first part 41 can be inserted into the first limiting groove 52 of the sewage pipe 5. The stability and sealing of the connection between the sewage pipe 5 and the installation cover 6 can be achieved through the setting of the sealing tube.

[0059] Furthermore, the first portion 41 and the second portion 42 extend in the same direction and are collinear, and the distance between the first portion 41 and the second portion 42 and the axis of the pipe body segment 1 is greater than the radius of the pipe body segment 1 .

[0060] By setting the distance between the first part 41 and the second part 42 and the axis of the pipe body section 1 to be greater than the radius of the pipe body section 1, it is convenient to install the sealing pipe relative to the pipe structure by snapping the second annular rib 4 into the interior of the corresponding pipe structure, which is beneficial to improving the installation efficiency and stability of the sealing pipe.

[0061] Specifically, when the sealing pipe, the mounting cover 6 and the sewage pipe 5 are connected, the structural setting of the second annular rib 4 does not affect the cooperation between the first annular rib 3 and the sewage pipe 5 .

[0062] It should be noted that when the distance between the first part 41 and the second part 42 and the axis of the pipe body segment 1 is equal to the radius of the pipe body segment 1, the second annular rib 4 will be stuck in the matching structure set on the mounting cover 6 and the sewage pipe 5, and the first annular rib 3 cannot be set between the outer wall of the pipe body segment 1 and the inner wall of the sewage pipe 5, which will affect the sealing of the sewage pipe.

[0063] Furthermore, the surfaces of the first part 41 and the second part 42 on the side facing the axis of the pipe body section 1 are coplanar. By making the surfaces of the first part 41 and the second part 42 on the side facing the axis of the pipe body section 1 coplanar, a sealing surface is formed by the surfaces of the first part 41 and the second part 42 facing the pipe body section 1 that are in contact with each other, which is beneficial to improving the sealing effect; at the same time, the setting of the coplanar surface also facilitates the contact between the first part 41 and the second part 42 to achieve force balance, which is beneficial to improving the stability of the installation of the sealing tube.

[0064] In this embodiment, preferably, the first portion 41 is formed as a third annular rib extending along the axial direction of the tubular body segment 1 , and the second portion 42 is formed as a fourth annular rib extending along the axial direction of the tubular body segment 1 .

[0065] Among them, the first part 41 and the second part 42 are extended along the axial direction of the tube body segment 1 to increase their axial length. In this way, when the first part 41 and the second part 42 cooperate with other components, the axial increase of the first part 41 and the second part 42 is beneficial to increase the contact area between the first part 41 or the second part 42 and the remaining components, thereby increasing the stability of the first part 41 and the second part 42 in cooperating with other components.

[0066] In this embodiment, the first portion 41 and the second portion 42 adopt the structure of an annular rib extending along the axis to form two annular ribs on both sides of the circumferential flange 21 , thereby facilitating improving the sealing performance at the circumferential flange 21 .

[0067] Furthermore, along the axial direction of the tube body section 1, the first portion 41 and the second portion 42 are respectively connected to both sides of the circumferential flange 21. Alternatively, the second annular rib 4 further includes a connecting portion 43 disposed between the first portion 41 and the second portion 42, and the outer peripheral surface of the circumferential flange 21 is connected to the inner wall surface of the connecting portion 43.

[0068] Furthermore, the extension lengths of the first portion 41 and the second portion 42 along the axial direction of the tube body segment 1 may be the same or different, and may be adaptively set according to actual conditions.

[0069] According to different actual conditions and processing environments, the first part 41 and the second part 42 have different installation and processing methods to facilitate the processing and forming of the first part 41 and the second part 42.

[0070] like Figures 1 to 5 As shown, the sealing tube also includes a connecting pipe section 8. Along the axial direction of the pipe body section 1, the first end of the connecting pipe section 8 is connected to the pipe body section 1, and the circumferential flange 21 is connected to the outer peripheral surface of the second end of the connecting pipe section 8. The pipe diameter of the first end of the connecting pipe section 8 is smaller than the pipe diameter of the second end to form an axial expansion structure.

[0071] The sealing tube is divided into three sections by setting the connecting tube section 8, and a complete sealing tube is formed by setting the connecting tube section 8 between the tube body section 1 and the sealing tube section 2. The connecting tube section 8 adopts a flared structure to reduce the radial extension length of the sealing tube section 2, thereby increasing the overall strength of the sealing tube and ensuring the stability of the installation of the sealing tube.

[0072] At the same time, in order to reduce the interference with the first annular rib 3 during the installation of the sealing pipe, the expansion structure of the connecting pipe section 8 can increase the distance between the second annular rib 4 and the axis of the pipe body section 1, and make this distance greater than the radius of the pipe body section 1. In this way, during the installation of the sealing pipe, it is possible to avoid the situation where the distance between the outer wall of the pipe body section 1 and the inner wall of the sewage pipe 5 is too small, thereby affecting the installation of the sewage pipe 5.

[0073] In this embodiment, one or more first annular ribs 3 are provided. When more than one first annular ribs 3 are provided, the more than one first annular ribs 3 are spaced apart in the axial direction of the tube section 1 .

[0074] In order to improve the sealing effect of the sealing tube, a plurality of first annular ribs 3 may be provided. When a plurality of first annular ribs 3 are provided, each of the first annular ribs 3 can play a sealing role, and the structure of the plurality of first annular ribs 3 is conducive to enhancing the sealing performance of the sealing tube.

[0075] In this embodiment, the distance between the outer surface of the first annular rib 3 and the axis gradually increases in the direction toward the sealing pipe section 2, and the outer peripheral surface of the first annular rib 3 is formed into an oblique structure 31. By setting the outer peripheral surface of the first annular rib 3 into the oblique structure 31, the oblique structure 31 can play a guiding role during the installation of the sealing pipe, thereby facilitating the installation of the sealing pipe.

[0076] Embodiment 2

[0077] This embodiment provides a pipe group structure, see Figures 1 to 16 The pipe group structure includes the sealing pipe in the implementation method, and the pipe group structure also includes a drain pipe 5 and a mounting cover 6. The mounting cover 6 is connected to the drain pipe 5. Along the axial direction of the sealing pipe, at least a portion of the circumferential flange 21 of the sealing pipe abuts between the drain pipe 5 and the mounting cover 6; along the radial direction of the sealing pipe, the first portion 41 abuts against the drain pipe 5 for a limit position, and the second portion 42 abuts against the mounting cover 6 for a limit position.

[0078] Specifically, the pipe group structure is installed with the toilet body to meet the sewage discharge requirements of the toilet body. During the installation of the pipe group structure, the sealing pipe is installed between the installation cover 6 and the sewage discharge pipe 5 to increase the sealing performance of the connection between the installation cover 6 and the sealing pipe.

[0079] Furthermore, the sewage pipe 5 is used to abut and limit the first part 41 of the sealing pipe, and the installation cover 6 is used to abut and limit the second part 42 of the sealing pipe. This can increase the installation stability between the sewage pipe 5, the installation cover 6 and the sealing pipe, thereby ensuring the working stability of the entire pipe group structure.

[0080] Furthermore, the two axial surfaces of the circumferential flange 21 abut against the sewage pipe 5 and the mounting cover 6 respectively to form a seal between the circumferential flange 21 and the sewage pipe 5 and the mounting cover 6, thereby achieving a sealed connection between the sewage pipe 5 and the mounting cover 6 through the sealing pipe, thereby increasing the sealing performance of the pipe group structure.

[0081] Specifically, a first abutment protrusion 51 of an axially extending annular structure is provided on the end face of the open end of the sewage pipe 5, and a second abutment protrusion 61 of an annular structure opposite to and spaced from the first abutment protrusion 51 is provided on the mounting cover 6 along the axial direction of the sealing tube, and the circumferential flange 21 is abutted between the first abutment protrusion 51 and the second abutment protrusion 61; the first part 41 abuts against the side of the first abutment protrusion 51 away from the axis of the sealing tube, and the second part 42 abuts against the side of the second abutment protrusion 61 away from the axis of the sealing tube.

[0082] Among them, the first abutment protrusion 51 abuts and cooperates with the first part 41, and the second abutment protrusion 61 abuts and cooperates with the second part 42. The first abutment protrusion 51 and the second abutment protrusion 61 can limit the axial direction of the sealing tube through the limiting of the first abutment protrusion 51 and the second abutment protrusion 61, thereby improving the stability and installation strength of the sealing tube.

[0083] It is understandable that a single first abutting protrusion 51 or a single second abutting protrusion 61 can only limit the movement of the sealing tube in one axial direction, and cannot ensure the installation stability of the sealing tube, and thus cannot improve the sealing performance of the tube group structure.

[0084] In this embodiment, the circumferential flange 21 is abutted between the first abutting protrusion 51 and the second abutting protrusion 61, so that the first abutting protrusion 51 and the second abutting protrusion 61 can limit the movement of the sewage pipe 5 in the axial direction together, block the movement of the sewage pipe 5 in the axial direction, and increase the stability of the installation of the sewage pipe 5.

[0085] Furthermore, a first limiting groove 52 is formed between the first abutting protrusion 51 and the end face of the open end of the sewage pipe 5, and the first part 41 is abutted against the inside of the first limiting groove 52. The first part 41 is placed in the first limiting groove 52 to facilitate the limitation of the sewage pipe 5.

[0086] Further, the mounting cover 6 includes a first arm section 62 and a second arm section 63, the first arm section 62 extends along the axial direction of the sealing tube, the first arm section 62 is connected to the outer surface of the sewage pipe 5, the second arm section 63 is arranged at one end of the first arm section 62 and is bent toward one side of the axis of the first arm section 62, the second abutting protrusion 61 is connected to one end of the second arm section 63 away from the first arm section 62, the first arm section 62 and the second abutting protrusion 61 extend in the same direction, the second arm section 63 and the second abutting protrusion 61 form a second limiting groove 64, and the second part 42 abuts against the inside of the second limiting groove 64. Placing the second part 42 in the second limiting groove 64 facilitates limiting the sewage pipe 5.

[0087] The mounting cover 6 includes a first arm segment 62 , a second arm segment 63 and a second abutting protrusion 61 which are bent in sequence, and a second limiting groove 64 is formed between the first arm segment 62 , the second arm segment 63 and the second abutting protrusion 61 .

[0088] Preferably, the mounting cover 6 comprises a first arm section 62 , a second arm section 63 and a second abutting protrusion 61 which are formed by vertical bending in sequence.

[0089] In this embodiment, the sewage pipe 5 includes a main pipe section 53 and a joint pipe section 54. The joint pipe section 54 is connected to the installation cover 6. The pipe diameter of the joint pipe section 54 is larger than the pipe diameter of the main pipe section 53. A butt end face is formed between the main pipe section 53 and the joint pipe section 54. The end of the pipe body section 1 of the sealing tube away from the sealing pipe section 2 abuts against the butt end face, and the first annular rib 3 of the sealing tube abuts against the inner wall surface of the joint pipe section 54.

[0090] Specifically, by making the diameter of the joint pipe section 54 larger than the diameter of the main body pipe section 53, a butt joint end face can be formed between the main body pipe section 53 and the joint pipe section 54. The butt joint end face abuts against the sealing tube, thereby achieving abutment limiting of the sealing tube, facilitating the installation and positioning of the sealing tube, and at the same time helping to increase the stability of the installation of the sealing tube.

[0091] Furthermore, by abutting the first annular rib 3 against the inner wall of the joint pipe section 54, it is helpful to form a seal between the sewage pipe 5 and the sealing pipe, thereby increasing the sealing performance of the connection between the sewage pipe 5 and the sealing pipe.

[0092] In this embodiment, the pipe group structure further includes a limiting assembly 7, which includes a first limiting member 71 provided on the sewage pipe 5 and a second limiting member 72 provided on the mounting cover 6, wherein the first limiting member 71 and the second limiting member 72 are provided in contact with each other along the axial direction of the sealing pipe, so as to achieve axial limiting of the sewage pipe 5 and the mounting cover 6, that is, the sewage pipe 5 and the mounting cover 6 cannot move relative to each other in the axial direction.

[0093] In one specific implementation of this embodiment, Figure 6 As shown, the first limiting member 71 is a convex ring of an annular structure, and the second limiting member 72 is an elastic buckle. The convex ring and the elastic buckle abut against each other along the axial direction of the sealing tube and can rotate relatively along the circumferential direction of the sealing tube.

[0094] Among them, the first limit member 71 and the second limit member 72 are axially abutted and limited to each other, which can limit the displacement of the sewage pipe 5 in the axial direction and increase the stability of the installation of the sewage pipe 5; at the same time, since the first limit member 71 is an annular structure, the first limit member 71 and the second limit member 72 can rotate 360° in the circumferential direction to achieve adaptive adjustment of the angle between the sewage pipe 5 and the installation cover 6.

[0095] In this embodiment, three elastic buckles are provided and are arranged at equal intervals along the circumference of the mounting cover 6 .

[0096] In another specific implementation of this embodiment, Figure 7As shown, the first limiting member 71 is a plurality of arc-shaped protrusions extending circumferentially along the joint pipe section 54 of the sewage pipe 5, and an escape area is formed between two adjacent arc-shaped protrusions. The second limiting member 72 is an elastic buckle, and the arc-shaped protrusions abut against the elastic buckle along the axial direction of the sealing tube and can rotate relative to each other along the circumference of the sealing tube. The mounting cover 6 has an axially extending rib 65, and at least a portion of the rib 65 is arranged inside the escape area for angle limiting.

[0097] The convex rib 65 is provided to limit the angle of the relative rotation between the sewage pipe 5 and the installation cover 6, so as to avoid the sewage pipe 5 from rotating or rotating at an excessive angle. Specifically, since the arc-shaped protrusion in this embodiment can stop the limiting convex rib 65, the convex rib 65 can only rotate circumferentially in the avoidance area, so as to limit the angle of the relative rotation between the sewage pipe 5 and the installation cover 6.

[0098] In this embodiment, if Figures 9 to 11 As shown, the sewage pipe 5 and the installation cover 6 can rotate around the axis of the installation cover 6, so that the sewage pipe 5 can be adjusted between multiple installation positions, thereby improving the application range of the sewage pipe 5.

The sewage pipe 5 can be suitable for sewer pipes in different scenarios through angle adjustment, that is, it is suitable for multiple pit distances.

[0099] Among them, when the sewage pipe 5 is placed vertically, the height difference between the lowest point of the sewage pipe 5 and the lowest point of the pipeline in the toilet body is the largest, and the siphon effect is the best at this time.

[0100] Furthermore, when the installation of the pipeline requires the sewage pipe 5 to be adjusted in angle, the sewage pipe 5 can be rotated to perform adaptive adjustment.

[0101] In this embodiment, three elastic buckles are provided and are arranged at equal intervals along the circumference of the mounting cover 6 .

[0102] In this embodiment, the main pipe section 53 of the sewage pipe 5 includes a first pipe section 531 and a second pipe section 532. The first end of the first pipe section 531 is connected to the joint pipe section 54, and the second end of the first pipe section 531 is connected to the second pipe section 532. The second pipe section 532 can rotate around the axis of the second end of the first pipe section 531.

[0103] Specifically, the sewage pipe 5 can rotate relative to the installation cover 6, and the two pipe sections of the sewage pipe 5 can also rotate relative to each other, so that it can adapt to different installation spaces during the installation process, reduce the limitations of space factors, and facilitate the installation of the sewage pipe 5.

[0104] like Figures 12 to 16As shown, the first pipe section 531 and the second pipe section 532 are rotatably matched to enable the second pipe section 532 to rotate around Fig.13 The axis of the second end of the first pipe section 531 shown is rotated to realize that the second pipe section 532 has multiple installation positions, thereby improving the applicable scope of the sewage pipe 5. The sewage pipe 5 provided in this embodiment can realize displacement adjustment. By adjusting the second pipe section 532, the sewage pipe can be suitable for wall drainage or ground drainage. The sewage pipe 5 can be adjusted by angle to be suitable for sewer pipes in different scenarios, that is, suitable for multiple pit distances.

[0105] In this embodiment, the rotation structure between the first pipe segment 531 and the second pipe segment 532 can be a structure that cooperates with the annular rib and the buckle, or a structure that cooperates with the convex rib and the annular groove. Specifically, the annular rib and the buckle are respectively arranged on the first pipe segment 531 and the second pipe segment 532, the annular rib and the buckle abut against each other along the axial direction of the first pipe segment 531, and the annular rib and the buckle can rotate around the axis direction of the first pipe segment 531, that is, they rotate relatively along the circumference of the first pipe segment 531; the convex rib and the annular groove are respectively arranged on the first pipe segment 531 and the second pipe segment 532, the convex rib and the annular groove abut against each other along the axial direction of the first pipe segment 531, and the convex rib and the annular groove can rotate around the axis direction of the first pipe segment 531, that is, they rotate relatively along the circumference of the first pipe segment 531.
