[0031] In order to better understand the purpose, function and specific design of the utility model, the drainer of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1 , Figure 2 , Fig.11 , Fig.12 , Fig.13 and Fig.15 As shown, the drain of the utility model includes a main body 1, a lower connecting member 2 is arranged at the bottom of the main body 1, a plurality of connecting petals 22 of the lower connecting member 2 extend into the interior of the main body 1, a thread 221 matching with the steel head 8 is arranged on the upper inner side of the connecting petal 22, the upper outer side of the connecting petal 22 is an arc-shaped end surface 222, an upper connecting member 3 is arranged on the top of the main body 1, the upper connecting member 3 is sleeved on the connecting petal 22 of the lower connecting member 2, and an arc-shaped surface 31 matching with the arc-shaped end surface 222 of the connecting petal 22 is arranged on the inner wall of the upper connecting member 3, the upper connecting member 3 is rotated so that the arc-shaped surface 31 of the upper connecting member 3 rotates along the corresponding arc-shaped end surface 222 of the connecting petal 22, so as to reduce or expand the upper end diameter of the lower connecting member 2 (that is, the accommodating space formed by the plurality of connecting petals 22), so as to adapt to steel heads 8 of different calibers.

[0033] Specifically, if Figure 2 , Fig.11 , Fig.12 and Fig.13 As shown, the lower connecting member 2 includes a sealing cover 23, a support seat 21 and connecting petals 22 evenly distributed along the circumference of the support seat 21, and there is a gap between the connecting petals 22. The steel head 8 is inserted into the lower connecting member 2, and the upper connecting member 3 is rotated so that the connecting petals 22 can be deformed by force and move closer to each other to apply a clamping force to the steel head 8, thereby clamping the steel head 8.

[0034] The inner wall of the sealing cover 23 is provided with an internal thread 231, and the lower part of the support seat 21 is provided with an external thread 212 that matches the internal thread of the sealing cover 23. The sealing cover 23 is screwed on the lower part of the support seat 21, and the bottom of the main body 1 is sealed by the sealing cover 23, and at the same time, the debris at the bottom of the main body 1 can be cleaned.

[0035] The upper part of the support seat 21 is provided with a first annular groove 211, and the lower inner wall of the main body 1 is provided with a first protrusion 13 matched with the first annular groove 211, and the number of the first protrusion 13 is at least 2. The first protrusion 13 on the main body 1 is inserted into the first annular groove 211 of the support seat 21 and can slide along the first annular groove 211. The upper part of the support seat 21 is also provided with a sealing groove 213 for installing a sealing ring, and the sealing between the lower connecting member 2 and the main body 1 is ensured by the sealing ring.

[0036] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the two adjacent arc surfaces 31 of the upper connecting member 3 are staggered so that a stop portion 33 is formed between the arc surfaces 31 and the arc surfaces 31. The stop portion 33 can abut against the connecting flap 22 to limit the rotation of the upper connecting member 3. When the stop portion 33 abuts against the connecting flap 22, the upper end diameter of the lower connecting member 2 is the largest.

[0037] like Figure 1 , Figure 7 and Fig.11 As shown, the arcuate end surface 222 of the connecting flap 22 is tightly attached to the arcuate surface 31 of the upper connecting member 3, and a first anti-slip pattern 311 is arranged on the arcuate surface 31 of the upper connecting member 3. The arcuate end surface 222 of the connecting flap 22 is provided with a second anti-slip pattern 2221 which matches the first anti-slip pattern 311 of the arcuate surface 31. The first anti-slip pattern 311 and the second anti-slip pattern 2221 are both vertical anti-slip patterns, and the first anti-slip pattern 311 is engaged with the second anti-slip pattern 2221, which can increase the friction between the upper connecting member 3 and the connecting flap 22.

[0038] like Figure 2 , Figure 3 , Figure 4 and Fig.14As shown, a connector 11 is provided on one side of the main body 1, and a second annular groove 111 is provided on the connector 11. A second protrusion 44 matching with the second annular groove 111 is provided on the inner wall of the first interface 41 of the connecting pipe 4, and the number of the second protrusion 44 is at least 2. The second protrusion 44 on the connecting pipe 4 is inserted into the second annular groove 111 of the connector 11, and can slide along the second annular groove 111, so that the connecting pipe 4 can rotate within a range of 360°. A receiving cavity 43 is provided in the first interface 41 of the connecting pipe 4, and a spring 431 and a positioning pin 432 are installed in the receiving cavity 43. The outer surface of the connector 11 is evenly distributed with a plurality of positioning holes 112 along the circumferential direction, and the positioning holes 112 cooperate with the positioning pin 432 to realize the positioning of the connecting pipe 4 after rotation. An external thread is provided on the second interface 42 of the connecting pipe 4, and the drain pipe is threadedly connected with the second interface 42. In order to ensure its sealing, a sealing ring is also provided at the connection. When in use, the connecting pipe 4 can be rotated arbitrarily according to the orientation of the drainage pipe, so that the drainage pipe can be better connected to the drainage pipe for drainage without clogging. The connecting pipe 4 is rotated so that the positioning pin 432 can be inserted into the positioning hole 112 under the action of the spring 431 to achieve the positioning of the connecting pipe 4, and the connecting pipe 4 can be effectively prevented from rotating even under the impact of a strong water flow.

[0039] The joint 11 is also provided with a sealing groove 112 for installing a sealing ring, and the sealing ring is used to ensure the sealing between the joint 11 and the connecting pipe 4.

[0040] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the joint 11 is provided with an anti-odor valve plate 7 inside, which can close the communication hole 14 of the main body 1 when no water flows through, so as to prevent the odor in the sewer pipe from overflowing through the communication hole 14, and prevent the sewage in the sewer pipe from flowing back from the communication hole 14. The connecting pipe 4 can be made of transparent material, so that the working state of the anti-odor valve plate 7 can be observed conveniently.

[0041] Two rotating shafts 71 are arranged on the deodorizing valve plate 7. A rotating shaft groove 16 for the rotating shaft 71 to be installed and a cover plate 15 for closing the rotating shaft groove 16 are arranged near the joint 11 of the main body 1. A convex column 151 is arranged on the cover plate 15. When installing, the rotating shaft 71 of the deodorizing valve plate 7 is installed in the rotating shaft groove 16, and then the convex column 151 of the cover plate 15 is inserted into the plug hole 17 of the main body 1. The deodorizing valve plate 7 is also provided with a mounting seat 72, and a counterweight is installed in the mounting seat 72. When water flows through the connecting hole 14 of the main body 1, the water flow will flush the deodorizing valve plate 7 open under the action of gravity, and the water will pass naturally. When the water flow stops, the deodorizing valve plate 7 will reset under the gravity of the counterweight and then close the connecting hole 14.

[0042] like Figure 2 , Figure 7 , Fig. 9 and Fig.10 As shown, the lower end of the upper connecting member 3 is provided with a buckle 32, the ferrule 5 is sleeved on the outside of the upper connecting member 3, and is stopped by the buckle 32, and the ferrule 5 is provided with a third annular groove 52. The upper inner wall of the main body 1 is provided with a third protrusion 12 that matches the third annular groove 52, and the number of the third protrusions 12 is at least 2. The third protrusion 12 on the main body 1 is inserted into the third annular groove 52 of the ferrule 5 and can slide along the third annular groove 52, so that the main body 1 can achieve 360° rotation by relying on the first protrusion 13 and the third protrusion 12. The ferrule 5 is also provided with a sealing groove 53 for installing a sealing ring, and the sealing between the ferrule 5 and the main body 1 is ensured by the sealing ring.

[0043] A spring slot 51 is provided at the upper end of the clamping sleeve 5 , and a spring 6 is installed in the spring slot 51 . One end of the spring 6 abuts against the spring slot 51 , and the other end of the spring 6 abuts against the upper connecting member 3 .

[0044] When in use, the drain of the utility model is adjusted according to the caliber of the steel head 8. When adjusting, the upper connecting member 3 is rotated so that the arc surface 31 of the upper connecting member 3 rotates along the arc end surface 222 of the corresponding connecting flap 22 to reduce or expand the upper end diameter of the lower connecting member 2 (i.e., the accommodating space formed by the multiple connecting flaps 22) to adapt to the steel head 8. In order to facilitate the insertion of the steel head 8, when adjusting, the upper end diameter of the lower connecting member 2 (i.e., the accommodating space formed by the multiple connecting flaps 22) can be adjusted to be slightly larger than the caliber of the steel head 8. After the adjustment is completed, the lower end of the steel head 8 is passed through the drain hole of the wash basin, mop pool or bathtub, and then the drain is put on the lower part of the steel head 8. At this time, the thread 221 of the inner wall of the connecting flap 22 is stuck on the steel head 8, and the upper connecting member 3 is rotated so that the connecting flaps 22 are deformed by force and close to each other to apply a pressing force to the steel head 8, thereby clamping the steel head 8. Rotate the main body 1 and press the connecting piece 3 upward, the connecting petals 22 will continue to be forced to move closer to each other. At this time, the spring 6 is in a contracted state, exerting a greater clamping force on the steel head 8, so that the drain can better lock the steel head 8.

[0045] When it is necessary to remove the drain, the upper connecting member 3 is rotated to expand the connecting flap 22 outward to release the clamping of the steel head 8, and the drain can be removed.

[0046] The main body 1, the upper connecting piece 3, the ferrule 5, the lower connecting piece 2 and the connecting pipe 4 of the water drainer are all made of plastic material, ensuring that the exterior of the steel head 8 will not be corroded and thus cannot be removed.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
