[0002] At present, a drain outlet is provided at the bottom of the kitchen sink basin or the bottom of the washbasin or bathtub in the bathroom. A drain is installed on the drain outlet, and the water outlet of the drain is provided with an external thread. The drain pipe and the water outlet of the drain are screwed together by sleeve- ing a fastening ring on the drain pipe. Most of the existing drain pipes are flexible corrugated pipes. Both ends of the corrugated pipe need to retain straight head parts due to the clamping head of the machine production. That is, the two ends of the corrugated pipe are respectively extended with straight pipe sections that cannot be bent. During installation, the straight pipe section at one end of the corrugated pipe is sealed with the water outlet of the drain, and the straight pipe section at the other end is sealed with the sewer pipe, so that the water in the basin or washbasin can be smoothly discharged into the sewer through the drain pipe.

[0003] However, during actual installation, due to differences in decoration styles and cabinet heights, if the space between the bottom of the cabinet and the sewer pipe is relatively narrow, the use of the above-mentioned traditional drain pipe will affect the installation height because the straight pipe section cannot be bent, making it difficult to install or having excess corrugated pipes exposed after installation, which not only affects the appearance but also leads to a waste of space; if the space between the bottom of the cabinet and the sewer pipe is relatively spacious, the conventional drain pipe may be unable to be installed due to its short length due to its lack of flexibility in design, lacking versatility and having a small scope of application.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figures 1 to 3 A drain connection pipe includes a bellows 10 with a continuous corrugated structure. In this embodiment, the bellows 10 is made of metal (such as stainless steel). One end of the bellows 10 is defined as a water inlet end 11, and the other end is defined as a water outlet end 12. The water inlet end 11 of the bellows 10 is provided with a first fastening ring 111, and the first fastening ring 111 is screwed with an adapter assembly. The adapter assembly includes an adapter tube 20, one end of the adapter tube 20 is screwed with the first fastening ring 111, and the other end is screwed with There is a second fastening ring 21 for connecting to the water outlet of the drain, wherein one end of the first fastening ring 111 and the second fastening ring 21 are respectively protruded inward with a first annular surrounding wall 112 and a second annular surrounding wall 211, and a sealing assembly is also provided between the first fastening ring 111 and the adapter assembly. The sealing assembly includes a first O-ring 13, a second O-ring 14 and a limiting ring 15 which are sequentially mounted on the end of the water inlet end 11, wherein the diameter of the limiting ring 15 is larger than the inner diameter of the first annular surrounding wall 112.

[0021] Reference Figures 1 to 3In this embodiment, the length of the adapter tube 20 is preferably 1 / 10 of the length of the bellows 10. In this way, when the height between the bottom of the cabinet and the sewer pipe is small, the installation space can be saved. One end of the adapter tube 20 is provided with a first external thread 22, and the other end is provided with a second external thread 23. The inner circumference of the first fastening ring 111 is provided with a first internal thread for screwing with the first external thread 22, and the inner circumference of the second fastening ring 21 is provided with a second internal thread for screwing with the second external thread 23. Through such an arrangement, the adapter tube 20 can be installed or removed according to the actual scenario, avoiding the situation where it cannot be installed due to compact space; the inner diameters of the first fastening ring 111 and the second fastening ring 21 are larger than the inner diameter of the bellows 10, and there is a gap between the second fastening ring 21 and the adapter tube 20. A third O-ring 24 is also provided for sealing. Through such an arrangement, when the diameter of the water outlet of the drain is smaller than the inner diameter of the bellows 10, the bellows 10 can be directly put on the water outlet of the drain, and then connected through the first fastening ring 111 or the second fastening ring 21; and the diameter of the third O-ring 24 is larger than the inner diameter of the second annular wall 211, so as to avoid the third O-ring 24 falling off during use, thereby ensuring the sealing effect; and the water outlet end 12 of the bellows 10 is also sequentially provided with a sealing plug 121 and a decorative cover 122, wherein the sealing plug 121 is made of rubber material and is used to be inserted into the sewer pipe to avoid odor back-odor, and the decorative cover 122 can not only improve the aesthetics, but also further increase the sealing performance of the sealing plug 121.

[0022] Reference Figures 1 to 3 When in use, if the diameter of the water outlet of the drain is smaller than the inner diameter of the bellows 10 and there is a large space between the water outlet of the drain and the sewer pipe, there is no need to disassemble the adapter pipe 20. You only need to remove the second fastening ring 21 from the adapter pipe 20, and then put the second fastening ring 21 on the water outlet of the drain, then align the end of the bellows 10 connected to the adapter pipe 20 with the water outlet of the drain, and then rotate the second fastening ring 21 to screw it with the second external thread 23 of the adapter pipe 20, and then insert the water outlet end 12 of the bellows 10 into the sewer pipe to complete the bellows. Installation of pipe 10; If the diameter of the water outlet of the drain is larger than the inner diameter of the bellows 10 and the space between the water outlet of the drain and the sewer pipe is relatively compact, first remove the adapter pipe 10 from the bellows 10, then align the first fastening ring 111 on the bellows 10 with the water outlet of the drain, then rotate the first fastening ring 111 to screw it together with the water outlet of the drain, then bend the bellows 10 according to the space, and finally insert the adjusted water outlet end 12 of the bellows 10 into the sewer pipe to complete the installation of the bellows 10.
