Description

Technical Field

[0001] This utility model belongs to the field of toilet sewage technology, and specifically refers to a universal sewage connection structure. Background Technology

[0002] Due to differences in size / model during design and production by different manufacturers, as well as differences in the design and construction precision of sewage pipes during building construction, when the sewage pipe of the toilet cannot be directly connected to the ground or wall, a sewage connection structure is required for conversion.

[0003] In existing technologies, sewage connection structures are sometimes made of flexible hoses, which are more flexible and applicable, but they are not strong enough, have a short service life, and are prone to breakage; while rigid pipes, although strong enough to meet the requirements, have relatively fixed connection ports at both ends, which cannot be adjusted and have poor applicability. Utility Model Content

[0004] The main purpose of this utility model is to provide a universal sewage connection structure to solve the problems existing in the prior art. It can flexibly adjust the distance between the two connection ports to adapt to different application scenarios.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A universal sewage connection structure includes a first connecting pipe and a second connecting pipe; the first connecting pipe has a first connecting end and a second connecting end at its two ends, and the axes of the first connecting end and the second connecting end are not collinear; the second connecting pipe has a third connecting end and a fourth connecting end at its two ends; the first connecting end is used to connect to the sewage bend of a toilet, and the fourth connecting end is used to connect to a sewage pipe installed on a wall or the ground; the second connecting end is dynamically and rotatably fitted within the third connecting end.

[0007] The first connecting pipe has a neck between the first connecting end and the second connecting end, and the cross-sectional area of ​​the neck is smaller than the cross-sectional area of ​​other parts of the first connecting pipe.

[0008] The upper end face of the first connecting end is provided with a stepped portion, which extends outward along the radial direction of the first connecting end and then extends upward to form a mounting ring, and a first sealing ring is provided inside the mounting ring.

[0009] A limiting ring is provided at the upper end of the circumference of the second connecting end, and a second sealing ring is provided below the limiting ring and sleeved on the second connecting end; the second connecting end passes downward into the third connecting end, and the second sealing ring is tightly fitted on the inner wall of the third connecting end.

[0010] The fourth connecting end is a bent pipe, or the fourth connecting end is an axial opening of the second connecting pipe.

[0011] After adopting the above technical solution, the present invention has the following technical effects:

[0012] This utility model allows for arbitrary adjustment of the distance between the first and fourth connecting ends through the rotational engagement of the first and second connecting pipes. This enables it to adapt to different distances (i.e., pit distances) between toilet drain bends and building drain pipes in practical applications, thereby improving the flexibility of toilet installation. Furthermore, both the first and second connecting pipes can be made of hard and high-strength materials, ensuring the strength and service life of the connection structure.

[0024] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0025] refer to Figure 1-5As shown, this utility model discloses a universal sewage connection structure, including a first connecting pipe 1 and a second connecting pipe 2;

[0026] The first connecting pipe 1 has a first connecting end 11 and a second connecting end 12 at its two ends, respectively, and the axes of the first connecting end 11 and the second connecting end 12 are not collinear.

[0027] The two ends of the second connecting pipe 2 are respectively provided with a third connecting end 21 and a fourth connecting end 22;

[0028] The first connecting end 11 is used to connect the toilet's drain pipe a, and the fourth connecting end 22 is used to connect the drain pipe installed on the wall or the ground.

[0029] The second connecting end 12 is dynamically and sealingly fitted within the third connecting end 21.

[0030] Through the above solution, this utility model can arbitrarily adjust the distance between the first connecting end 11 and the fourth connecting end 22 by rotating the first connecting pipe 1 and the second connecting pipe 2, thereby adapting to different distances (i.e., pit distance) between toilet drain bends and building drain pipes in actual use scenarios, improving the flexibility of toilet installation; at the same time, both the first connecting pipe 1 and the second connecting pipe 2 can be made of hard and high-strength materials to ensure the strength and service life of the connection structure.

[0031] refer to Figure 1-4 The first embodiment of the present invention is shown in the figure.

[0032] The first connecting pipe 1 is provided with a constriction 13 between the first connecting end 11 and the second connecting end 12. The cross-sectional area of ​​the constriction 13 is smaller than that of other parts of the first connecting pipe 1. As a result, there is a section where the cross-section decreases sharply between the two. When sewage passes through the constriction 13, it is accelerated, thereby improving the siphon effect.

[0033] The upper surface of the first connecting end 11 is provided with a stepped portion 14. The stepped portion 14 extends radially outward along the first connecting end 11 and then extends upward to form a mounting ring 15. A first sealing ring 3 is provided inside the mounting ring 15. During assembly, the lower end of the toilet's drain pipe a passes through the first sealing ring 3 to achieve a seal and abuts against the stepped portion 14.

[0034] A limiting ring 16 is provided at the upper end of the circumference of the second connecting end 12, and a second sealing ring 4 is provided below the limiting ring 16 and fitted onto the second connecting end 12. The second connecting end 12 is inserted downward into the third connecting end 21, and the second sealing ring 4 is tightly fitted onto the inner wall of the third connecting end 21 to achieve a seal. By setting the limiting ring 16, the insertion depth of the second connecting end 12 can be ensured to meet the requirements, and the limiting ring 16 covers the gap between the second connecting end 12 and the third connecting end 21.

[0035] In the first embodiment, the fourth connecting end 22 is a downward-facing bent pipe for connecting to a sewage pipe installed on the ground.

[0036] refer to Figure 5 As shown, a second embodiment of the present invention is illustrated.

[0037] In the second embodiment, the fourth connecting end 22 is an axial opening of the second connecting pipe 2, so as to connect to the sewage pipe installed on the wall.

[0038] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
