Detailed Implementation

[0036] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Example 1

[0037] Please see Figures 1 to 4This invention relates to a sealing connection structure for a toilet, as described in Embodiment 1 of the present invention. The structure includes a connecting seal 001, which comprises a support portion 10, a first sealing portion 20, a first transition portion 30, and a second sealing portion 40. The support portion 10 is annular in shape. The first sealing portion 20 is positioned above the support portion 10; the first transition portion 30 is positioned below the support portion 10; and the second sealing portion 40 is positioned below the first transition portion 30. The support portion 10, the first sealing portion 20, the first transition portion 30, and the second sealing portion 40 are integrated into a single unit. The sealing connection structure of this invention utilizes the first sealing portion 20 and the second sealing portion 40. The upper surface of the first sealing portion 20 contacts the bottom of the toilet bowl for sealing, while the second sealing portion 40 is embedded in the bottom drain pipe for sealing. The first transition portion 30 is also provided to facilitate a smoother connection between the toilet bowl and the bottom drain pipe.

[0038] Please refer to the details. Figure 2 A support structure 002 is provided below the support part 10 near the edge. In this embodiment, the support structure 002 includes a support ring 71 provided below the support part 10 and several elastic parts 72 provided between the support part 10 and the support ring 71. By providing the support ring 71, elastic parts 72 and support part 10, it can adapt to the use of different working conditions. Specifically, the distance between the end face of the bottom connection of the toilet and the ground is the height difference. The setting of the support ring 71 and elastic parts 72 can adapt to the height difference within a certain range. If the height difference is small, the elastic parts 72 can be squeezed after the toilet is installed to ensure the sealing of the support part 10 and the support ring 71. At the same time, this embodiment eliminates the use of flange, making the installation of the connecting seal 001 more convenient.

[0039] Please refer to the details. Figure 2 The support ring 71, the elastic part 72 and the connecting seal 001 are integrally formed. During installation, only the connecting seal 001 needs to be installed to achieve a good sealing effect, resulting in high installation efficiency.

[0040] Please refer to the details. Figure 3 The first transition part 30 includes at least one "S"-shaped pleated ring. Multiple pleated rings can be set as needed. When there is some deviation between the central axis of the drain outlet at the bottom of the toilet and the central axis of the drain pipe on the ground, it can be better adapted for use. Moreover, when the bottom surface is uneven, it can be appropriately shifted left, right, front, and back to achieve a better sealing effect. The more pleated rings there are, the greater the shift position that can be adapted.

[0041] Please refer to the details. Figure 4At least one first annular sealing step 21 is provided on the upper end surface of the first sealing part 20. If two or more first annular sealing steps 21 are provided, the first annular sealing steps 21 are arranged sequentially from the outside to the inside from the upper end surface of the first sealing part 20. The vertical cross-sectional shape of the first annular sealing step 21 is triangular or semi-circular, and the horizontal cross-sectional area of ​​the first annular sealing step 21 increases sequentially from top to bottom. In this embodiment, the first annular sealing steps 21 can contact the bottom surface of the toilet, which can prevent poor sealing caused by uneven bottom surface, so as to achieve good sealing effect and prevent air leakage.

[0042] Please refer to the details. Figure 3 , Figure 4 The second sealing part 40 has a second annular sealing step 41 disposed on the outer side, and the second annular sealing step 41 is provided in at least one ring. If two or more second annular sealing steps 41 are provided, the second annular sealing steps 41 are arranged sequentially from top to bottom; the cross-sectional shape of the second sealing step along the vertical direction is rectangular or semi-circular, and the cross-sectional shape is the shape exposed after being half-sectioned along a specified direction. In this embodiment, the provision of the second annular sealing steps 41 can make the seal between the second sealing part 40 and the ground sewage pipe better, and the multiple second annular sealing steps 41 can improve the stability and life of the seal. Example 2

[0043] Please see Figures 5 to 7 This is a sealing connection structure for a toilet as an embodiment 2 of the present invention. The difference between this embodiment and embodiment 1 lies in the different support structure 002. In embodiment 2, the support structure 002 adopts a support flange 81, which is sleeved on the outside of the connecting seal 001 and located below the support part 10. The support flange 81, together with the support part 10 and the first sealing part 20, ensures the sealing effect between the top of the connecting seal 001 and the bottom surface of the toilet. Specifically, the support flange 81 can be locked to the ground to limit the position of the connecting seal 001.

[0044] Please refer to the details. Figure 6 A positioning hole 811 is provided on the support flange 81, and a positioning step 11 is provided below the support part 10 for cooperating with the positioning hole 811. At least two positioning holes 811 and positioning steps 11 are provided. The positioning hole 811 and positioning step 11 can be used to position and connect the sealing element 001. The shape and structure of the positioning step 11 can be referred to the attached figure. Example 3

[0045] Please see Figures 8 to 10This is a sealing connection structure for a toilet as an embodiment 3 of the present invention. The difference between this embodiment and embodiment 2 is that a second transition portion 50 and a third sealing portion 60 are added. Specifically, the sealing connection structure also includes a second transition portion 50 disposed below the second sealing portion 40 and a third sealing portion 60 disposed below the second transition portion 50. The second transition portion 50 is similar to the first transition portion 30, and the structure of the third sealing portion 60 is consistent with the structure of the second sealing ring. A third annular sealing step is also provided on the outer side of the third sealing portion 60. Through the provision of the second transition portion 50 and the third sealing portion 60, the length of the entire connecting seal 001 is increased, which can be better used when the central axis distance between the drain outlet under the toilet and the drain pipe on the ground is large.

[0046] In summary, the sealing connection structure of this utility model provides a first sealing part and a second sealing part. The upper surface of the first sealing part contacts the bottom of the toilet to provide a sealing function, and the second sealing part is embedded in the bottom drain pipe to provide a sealing function. A first transition part is also provided to facilitate a transition and better connect the toilet to the bottom drain pipe.

[0047] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
