Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, in particular to a sealing structure and a toilet installation flange with the sealing structure. Background Art

[0002] Traditional toilet installation usually involves the following steps: first, a sewage pipe will be pre-buried in the bathroom floor; then, the toilet sewage pipe needs to be precisely connected to the sewage pipe on the ground; in order to ensure a tight connection between the two, a toilet mounting flange is generally used for fixing, and sealing is achieved with the help of sealing materials such as butter, putty, and wax rings.

[0003] However, the existing toilet mounting flange structure has the following disadvantages:

[0004] 1. In actual applications, due to the large differences in construction standards in different construction periods, the size of the ground sewage pipes in some old buildings is relatively small, and the adaptability of the existing sealing structure is poor. At the same time, the toilet sewage pipes on the market are usually designed and manufactured according to the current building standards, which makes it difficult to match the toilet sewage pipes with the ground sewage pipes in old buildings. Although the existing mounting flange can be used for connection, this method often cannot effectively solve the sealing problem of the two. In addition, the transformation of the ground sewage pipes in old buildings is not only difficult but also costly, so it is not an ideal solution.

[0005] 2. The existing toilet installation flange performs well in ensuring the sealing between the ground sewage pipe and the toilet sewage pipe, but it is often not ideal when dealing with the sealing problem of the toilet side sewage pipe. In this case, even if the sealing of the ground sewage pipe is guaranteed, the poor sealing of the toilet side sewage pipe will lead to poor sealing of the entire system, thereby increasing the possibility of repairs and rework.

[0006] In view of this, the inventor specially designed a sealing structure and a toilet mounting flange having the sealing structure, and this case was thus generated. Utility Model Content

[0007] In order to solve the above problems, one of the technical solutions of the utility model is as follows:

[0008] A sealing structure is made of elastic material and comprises a side connecting ring body, an upper connecting ring body and a lower connecting ring body;

[0009] The side connection ring body is used to assemble the sealing structure onto the flange;

[0010] The upper connecting ring body is integrally bent along the inner side of the side connecting ring body toward a first direction perpendicular to the side connecting ring body to form an outer wall, and then integrally bent along the outer wall toward a second direction opposite to the first direction to form an inner wall, and a transition wall is formed between the outer wall and the inner wall;

[0011] The lower connecting ring body integrally extends along the bottom of the inner side wall toward the second direction and passes through the plane where the side connecting ring body is located;

[0012] The inner side of the inner side wall forms a contact surface whose diameter gradually decreases along the second direction, and the inner side wall and the lower connecting ring body are surrounded to form a sewage discharge channel that passes through from top to bottom.

[0013] Preferably, the transition wall is arc-shaped so that the upper connecting ring body forms an annular deformation groove opening toward the second direction and distributed around the central axis of the side connecting ring body.

[0014] Preferably, the side connecting ring body is a bottom wall which is arranged on the inner side of the outer side wall and is located at the bottom of the deformation groove and extends horizontally toward the center thereof.

[0015] Preferably, a plurality of reinforcing ribs for connecting the outer side wall, the inner side wall and the transition wall are provided in the deformation groove.

[0016] Preferably, the reinforcing ribs coincide with the radial direction of the circumference of the deformation groove and are evenly distributed around the circumference of the deformation groove.

[0017] Preferably, 2N reinforcing ribs are evenly arranged around the circumference of the deformation groove, where N=3, 4, or 5.

[0018] Preferably, the bottom wall is away from the bottom surface of the transition wall and is provided with a plurality of connecting parts on its circumferential edge, and the ends of the plurality of connecting parts away from the bottom wall all protrude in a direction away from the circumferential center of the bottom wall to form a hook.

[0019] Preferably, 2N connecting parts are evenly arranged around the circumference of the bottom wall, where N=3, 4, or 5.

[0020] Preferably, the contact surface is an inclined flat surface or an arc-shaped surface that changes linearly.

[0021] One of the technical solutions of the utility model is as follows:

[0022] A toilet mounting flange comprises the sealing structure and a flange, wherein the sealing element is assembled on the flange.

[0023] The beneficial effects of the utility model are as follows:

[0024] First, the utility model extends an upper connecting ring body vertically upward from the inner side of the side connecting ring body, and the diameter of the inner side wall thereof gradually decreases, thereby forming a contact surface matching the toilet side sewage pipe on the upper side of the sealing structure, thereby realizing a reliable sealed connection between the toilet side sewage pipe and the upper side of the sealing structure. In addition, the lower connecting ring body extends downward along the smaller diameter portion of the bottom of the inner side wall, forming a structure that can be inserted into the ground sewage pipe of an old building. When encountering a ground sewage pipe with a diameter larger than the lower connecting ring body, the lower connecting ring body can be extended into the ground sewage pipe by fixing the end of the ground sewage pipe to the lower end of the flange, thereby realizing effective sewage discharge.

[0025] Secondly, by arranging reinforcing ribs around the inside of the deformation groove, a stable fixed structure is formed between the inner wall and the outer wall, thereby avoiding excessive deformation due to force during the installation process and ensuring that the sealing connection between the toilet side sewage pipe and the ground sewage pipe is more stable and reliable.

[0026] In addition, the connection part and the hook at the end thereof can be conveniently matched with the flange to realize the rapid fixation of the sealing structure. At the same time, the entire toilet mounting flange can be easily fixed to the corresponding fixing surface through the flange, which simplifies the installation process and improves efficiency.

[0027] In particular, the contact surface is designed to be an inclined flat surface or an arc-shaped surface. Such a design allows the bottom of the toilet side sewage pipe to be inserted into the inner wall made of elastic material at a point corresponding to its diameter when it is pressed down along the contact surface, thereby causing the inner wall below this position to undergo appropriate deformation and tightly adhere to the outer wall of the sewage pipe, thereby achieving a better sealing effect.

[0028] In summary, the utility model achieves an effective sealed connection between the toilet side sewage pipe and the flange through an improved sealing structure, is compatible with the sizes of old buildings and existing ground sewage pipes, enhances structural stability, simplifies the installation process, and ensures better sealing effect through optimized contact surface design.

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] The utility model discloses a sealing structure and a toilet installation flange using the sealing structure. The sealing structure and the toilet installation flange are specifically described below through two embodiments. Example

[0044] See also Figures 1 to 9 , is a sealing structure as the best embodiment of the utility model, made of elastic material, including a side connecting ring body 10, an upper connecting ring body 20 and a lower connecting ring body 30;

[0045] The side connecting ring body 10 is annular in shape as a whole, and a hollow circular area is formed inside the side connecting ring body 10, which is used to assemble the sealing structure onto the flange 50;

[0046] The upper connecting ring body 20 is integrally bent along the inner side of the side connecting ring body 10 in a first direction perpendicular to the side connecting ring body 10 to form an outer wall 21, and then integrally bent along the outer wall 21 in a second direction opposite to the first direction to form an inner wall 22, and a transition wall 23 is formed between the outer wall 21 and the inner wall 22;

[0047] Specifically, in this embodiment, Figure 3 The first direction is upward along the axial direction of the side connecting ring body 10, and the second direction is downward along the axial direction of the side connecting ring body 10. The outer wall 21, the transition wall 23 and the inner wall 22 extend upward, horizontally and downward in sequence to form an annular deformation groove 24 opening downward, and the cross-section of the deformation groove 24 presents an inverted U-shape with an arc transition.

[0048] The lower connecting ring body 30 integrally extends toward the second direction along the bottom of the inner side wall 22 and passes through the plane where the side connecting ring body 10 is located, that is, the lower connecting ring body 30 integrally extends downward along the lower end of the inner side wall 22 with the smallest diameter, and passes through the plane where the side connecting ring body 10 is located, that is, when the side connecting ring body 10 is assembled with the flange 50, the lower end of the lower connecting ring body 30 also passes through the plane where the flange 50 is located, thereby forming an upper and lower distributed connection structure together with the upper connecting ring body 20, which can accurately realize the sealed connection of the toilet side sewage pipe 60 at the upper end of the flange 50 and the ground sewage pipe 60 at the lower end of the flange 50;

[0049] The inner side of the inner wall 22 forms a contact surface 221 whose diameter gradually decreases along the second direction. The inner wall 22 and the lower connecting ring body 30 enclose a sewage discharge channel 40 that passes through from top to bottom.

[0050] Preferably, Figure 2 , 3 As shown in , 4 , the transition wall 23 is arc-shaped so that the upper connecting ring body forms an annular deformation groove 24 which opens toward the second direction and is distributed around the central axis of the side connecting ring body 10 .

[0051] Preferably, Figure 4 , 5 As shown, the side connecting ring body 10 is a bottom wall arranged on the inner side of the outer wall 21 and located at the bottom of the deformation groove 24 and extending horizontally toward the center thereof. The setting of the bottom wall can facilitate the assembly connection between the sealing structure and the flange 50, that is, by pressing the flat bottom wall to the corresponding notch on the flange 50, a stable alignment of the sealing structure is achieved.

[0052] Furthermore, a plurality of reinforcing ribs 25 for connecting the outer side wall 21 , the inner side wall 22 and the transition wall 23 are provided in the deformation groove 24 . The reinforcing ribs 25 coincide with the radial direction of the circumference of the deformation groove 24 and are evenly distributed around the circumference of the deformation groove 24 .

[0053] In this embodiment, the reinforcing rib 25 is in the shape of a sheet, and the bottom wall also occupies a portion of the opening of the deformation groove 24 during the horizontal extension process. Therefore, when the reinforcing rib 25 is formed, part of the side of the reinforcing rib 25 is also connected to the end face of the bottom wall, and the remaining side is sequentially connected to the inner wall of the outer wall 21, the lower end face of the transition wall 23 and the outer wall of the inner wall 22, thereby forming a stable connection structure between the above structures, and through the distribution and number of the reinforcing ribs 25, a stable shaping structure can be formed between the inner wall 22 and the outer wall 21, thereby avoiding excessive deformation due to force during the installation process, ensuring that the sealing connection between the toilet side sewage pipe 60 and the ground sewage pipe 60 is more stable and reliable.

[0054] Specifically, 2N reinforcing ribs 25 are evenly arranged around the circumference of the deformation groove 24, N=3, 4, 5. In this embodiment, N is 4, that is, 8 reinforcing ribs 25 are evenly arranged around the circumference of the circle where the deformation groove 24 is located, thereby forming a stable connection structure to avoid excessive deformation due to force and ensure that the sealing connection between the toilet side sewage pipe 60 and the ground sewage pipe 60 is more stable and reliable.

[0055] Preferably, Figure 4 , 5 As shown in Figure 6, a plurality of connecting portions 11 are protruding from the bottom surface of the bottom wall away from the transition wall 23 and located on its circumferential edge. The ends of the plurality of connecting portions 11 away from the bottom wall all protrude in a direction away from the circumferential center of the bottom wall to form a hook portion 12. By providing the connecting portions 11 and the hook portions 12, and providing a plurality of grooves 55 around the flange 50, a convenient and stable connection between the sealing structure and the flange 50 can be achieved, thereby facilitating a sealed connection between the toilet and the bottom sewage pipe 60.

[0056] Specifically, 2N connecting parts 11 are evenly arranged around the circumference of the bottom wall, N=3, 4, 5, and in this embodiment, N is 4, that is, the number of connecting parts 11 and hook parts 12 is the same as the reinforcing ribs 25 and their positions are opposite to each other, thereby forming a more stable and reliable connection structure.

[0057] Preferably, Figure 2 , 3As shown, the contact surface 221 is an inclined flat surface or an arc-shaped surface that changes linearly. In this embodiment, the contact surface 221 is an inclined flat surface that changes linearly. The contact surface 221 is designed to be an inclined flat surface. Such a design allows the bottom of the toilet side sewage pipe 60 to be inserted into the inner side wall 22 made of elastic material at a point corresponding to its diameter when it is pressed down along the contact surface 221, so that the inner side wall 22 below this position is appropriately deformed and tightly attached to the outer side wall of the sewage pipe 60, thereby achieving a better sealing effect.

[0058] In particular, in this embodiment, the side wall of the lower connecting ring body 30 is inclined, that is, the angle between the cross section of the lower connecting ring body 30 and the vertical direction is α, and the lower connecting ring body 30 is inclined along the Figure 3 As shown, it gradually tapers downward and shrinks inward from top to bottom toward the center of the sewage channel 40. In this embodiment, the angle α is 2°. Therefore, through the shrinking design of the lower ring body 30, the lower end of the lower ring body 30 can form an inwardly contracted structure, which is convenient for inserting into the pipe mouth of the bottom sewage pipe 60. Example

[0059] like Figure 6 , 7 As shown in Figures 8 and 9, a toilet mounting flange includes a sealing structure and a flange 50, and a sealing member is assembled on the flange 50.

[0060] Specifically, the flange 50 includes a base plate 51 and a chassis 52, and a mounting groove 53 for the sealing structure to pass through is formed in the middle of the base plate 51 and the chassis 52. The upper and lower surfaces of the base plate 51 along its axial direction are surface A and surface B respectively, wherein a connecting inner ring 54 is horizontally arranged at the bottom of the inner ring surface of surface A, and 8 grooves 55 are evenly arranged at the contact position between the connecting inner ring 54 and the inner ring surface of the base plate 51 and around the circumference of the connecting inner ring 54. The grooves 55 are opposite to the 8 connecting parts 11 and the hook parts 12 in Example 1. After the hook parts 12 and the connecting parts 11 are inserted into the grooves 55 at the corresponding positions, the hook parts 12 are hooked on the surface B of the base plate 51, thereby realizing the initial connection of the sealing structure.

[0061] Among them, Figure 6 As shown, in order to facilitate the insertion of the hook portion 12 and the connecting portion 11, an inclined guide surface 551 is provided on one side of the plurality of slots 55 close to the mounting slot 53. The guide surface 551 is inclined from the A surface toward the direction close to the base plate 51, thereby forming a slot 55 shape that is larger at the top and smaller at the bottom, which facilitates the smooth insertion of the connecting portion 11 and the hook portion 12.

[0062] In addition, the B surface and the position connected to the inner ring 54 are axially contracted inward to form a hollow area 56 based on the bottom of the B surface, so that after the hook portion 12 passes through the slot 55, the hook portion 12 is hidden in the hollow area 56 to prevent the hook portion 12 from protruding from the bottom of the B surface. A ring-shaped limiting ring 57 is protruded upward along the axial direction on the inner ring surface of the chassis 52. The limiting ring 57 is provided with 8 clearance grooves 571 corresponding to the slot 55 one by one around its outer circumference. When the chassis 52 and the base plate 51 are assembled and spliced, the upper end surface of the chassis 52 is in contact with the B surface of the base plate 51, and the limiting ring 57 protrudes from the hollow area 56. The thickness of the limiting ring 57 is set to just support the top of the hollow area 56 (that is, the bottom surface connected to the inner ring 54). At this time, due to the existence of the clearance groove 571, the hook portion 12 enters the hollow area 56 after protruding from the slot 55 connected to the inner ring 54, and is just located in the clearance groove 571 of the corresponding area. Through the assembly of the chassis 52, the bottom surface of the flange 50 is closed, and the hook portion 12 is hidden in the area between the chassis 52 and the base plate 51, which fully avoids the connection between the sealing structure and the flange 50 from being affected by the outside, thereby maintaining the stability of the connection between the sealing structure and the flange 50.

[0063] In particular, if Figure 7 , 9 As shown, an annular limiting rib 58 is provided on the bottom surface of the chassis 52 and around the mounting groove 53. There is a certain gap between the limiting rib 58 and the mounting groove 53. By setting the annular rib and the gap, a larger diameter of the bottom surface sewage pipe 60 can be accommodated, so that it can be conveniently connected and sealed with the toilet mounting flange. Fig. 9 It is a schematic diagram of the cross-sectional connection structure between the bottom sewage pipe 60 with two different pipe diameters and the sealing structure, and both different pipe diameters can be adapted.

[0064] The beneficial effects of the utility model are as follows:

[0065] The utility model extends an upper connecting ring body 20 vertically upward from the inner side of the side connecting ring body 10, and the diameter of the inner side wall 22 thereof gradually decreases, so as to form a contact surface 221 matching the toilet side sewage pipe 60 on the upper side of the sealing structure, thereby realizing a reliable sealing connection between the toilet side sewage pipe 60 and the upper side of the sealing structure. In addition, the lower connecting ring body 30 integrally extends downward along the smaller diameter portion of the bottom of the inner side wall 22, forming a structure that can be inserted into the ground sewage pipe 60 of an old building. When encountering a ground sewage pipe 60 with a diameter larger than that of the lower connecting ring body 30, the lower connecting ring body 30 can be extended into the ground sewage pipe 60 by fixing the end of the ground sewage pipe 60 to the lower end of the flange 50, so as to realize effective sewage discharge.

[0066] In summary, the utility model achieves an effective sealed connection between the toilet side sewage pipe 60 and the flange 50 through an improved sealing structure, is compatible with the sizes of old buildings and existing ground sewage pipes 60, enhances structural stability, simplifies the installation process, and ensures better sealing effect through the optimized contact surface 221 design.

[0067] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
