DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-9 The utility model is described in further detail.

[0026] like Figure 1-3As shown, a sewer pipe joint includes a joint 1, a water inlet 11 of the joint 1 is connected to a sewer pipe 5 of a wash basin, a water outlet 12 of the joint 1 is connected to a drain pipe 6, and the other end of the drain pipe 6 is connected to a sewer on the ground. A connecting device 2 is provided between the water inlet 11 and the sewer pipe 5, and the connecting device 2 includes a mounting ring 21 and a clamping ring 22.

[0027] like Figure 4 As shown, the outer side of the bottom of the mounting ring 21 is provided with an external thread which is threadedly connected to the water inlet 11, and the inner side of the bottom of the mounting ring 21 is provided with an inner ring 211 extending inwardly, and the inner edge of the inner ring 211 is provided with a plurality of inner tooth plates 212 extending upwardly distributed at intervals along the circumferential direction, and the outer side of the inner tooth plates 212 is provided with a vertical groove 2121, and the plurality of inner tooth plates 212 form an inner gear ring, and the inner diameter of the inner gear ring is larger than the outer diameter of the sewer pipe 5, so that during installation, the sewer pipe 5 can be conveniently inserted into the inner gear ring first.

[0028] like Figure 4 , 5 As shown, the inner upper part of the snap ring 22 is provided with a support ring 221 extending inwardly along the circumferential direction, the inner edge of the support ring 221 is provided with a ring sleeve 222 extending downwardly along the circumferential direction, the inner side wall of the ring sleeve 222 is provided with a slide bar 2221 adapted to the corresponding groove 2121, and the side of the slide bar 2221 away from the ring sleeve 222 is inclined inwardly from top to bottom, that is, the slide bar 2221 is in a wedge shape with a larger top and a smaller bottom, and a plurality of hooks 223 are provided along the circumferential direction at the bottom of the ring sleeve 222, and a groove 2111 is provided on the inner ring 211 through which the corresponding hook 223 passes; the snap ring 22 is provided with a plurality of hooks 223 along the circumferential direction. It is located above the mounting ring 21 and embedded between the inner gear ring and the mounting ring 21, and the slide bar 2221 is slidably disposed in the corresponding groove 2121. The retaining ring 22 can slide up and down relative to the mounting ring 21, so that the slide bar 2221 drives the inner gear piece 212 to deform, that is, drives the inner diameter of the inner gear ring to change diameter; when the retaining ring 22 moves downward, the inner diameter of the inner gear ring becomes smaller, and when the retaining ring 22 moves upward, the thrust of the slide bar 2221 on the inner gear piece 212 is reduced, and the inner gear piece 212 is gradually reset under the action of the elastic force, that is, the inner diameter of the inner gear ring gradually increases.

[0029] A retaining ring 2112 for limiting the position of the snap ring 22 is provided in the middle of the inner wall of the mounting ring 21. By providing the retaining ring 2112, the snap ring 22 can be limited to move downward.

[0030] In this embodiment, four hooks 223 are provided. The movement of the snap ring 22 drives the hook 223 to slide in the slot 2111. When the hook 223 moves upward until it is caught by the inner ring 211, it limits the upward movement of the inner ring 211 and prevents the snap ring 22 from detaching from the mounting ring 21.

[0031] like Figure 2 , 6As shown, in order to facilitate the installation or removal of the mounting ring 21 and the connector 1, the mounting ring 21 and the connector 1 can also be connected by snapping. Specifically, an outer snap ring is provided at intervals along the circumferential direction on the outer side of the bottom of the mounting ring 21, and an inner snap ring is provided at intervals along the circumferential direction on the inner side of the water inlet 12 of the connector 1, and the length of the inner snap ring is less than the distance between two adjacent outer snap rings. During installation, the inner snap ring of the connector 1 is inserted into the mounting ring 21 from the distance between two adjacent outer snap rings, and then the connector is rotated a certain angle so that the inner snap ring is snapped on the inner side of the outer snap ring, and the mounting ring 21 and the connector 1 can be quickly snapped; the above operation is performed in reverse, and the mounting ring 21 and the connector 1 can be quickly removed.

[0032] like Figure 2 , 6 As shown in , 7, the working process of the connecting device 2 is as follows: the downpipe 5 is passed through the water outlet of the wash basin and penetrated into the inner gear ring. When the downpipe 5 is moved to the appropriate position, the connector 1 is pushed upward by hand. The lower surface of the wash basin will generate downward pressure on the clamping ring 22, forcing the clamping ring 22 to move downward relative to the mounting ring 21, and simultaneously driving the slide bar 2221 to move downward. The slide bar 2221 squeezes the corresponding inner gear piece 212, so that the inner diameter of the inner gear ring becomes smaller, and the inner gear ring and the outer thread of the downpipe 5 are quickly adapted to be threadedly connected. At this time, the downpipe 5 is rotated to quickly connect the outer thread of the downpipe 5 with the inner gear ring. The connecting device 2 does not need to thread the downpipe 5 with the inner gear ring throughout the entire process. The quick connection of the connector 1 and the downpipe 5 is achieved by reducing the diameter of the inner gear ring, reducing the number of circles of the threaded connection between the downpipe 5 and the inner gear ring, and achieving the purpose of quickly installing and disassembling the downpipe 5 and the connector 1.

[0033] When removing the water pipe 5, it is only necessary to loosen the water pipe 5 so that the external thread and the internal gear ring of the water pipe 5 are loosened. The squeezing of the lower surface of the basin on the clamping ring 22 is reduced, and the internal gear piece 212 rebounds outward under the action of its own elastic force, that is, the inner diameter of the internal gear ring becomes larger. When the hook 223 is stuck on the inner ring 211, the clamping ring 22 stops moving upward. At this time, the inner diameter of the internal gear ring is slightly larger than the outer diameter of the external thread of the water pipe 5. In this way, the water pipe 5 can be easily and quickly pulled out of the internal gear ring, thereby achieving the purpose of quickly removing the water pipe 5.

[0034] like Figure 5As shown, a plurality of drainage holes 2211 are respectively provided on the support ring 221. The purpose of providing the drainage holes 2211 is to prevent the water in the basin from overflowing when the basin has an overflow hole. The overflow hole is usually provided on the upper inner side of the basin, and the overflow hole is connected with the drainage hole of the basin outlet through the inner cavity of the basin. If the basin is blocked and the water in the basin exceeds the overflow hole, the water in the basin can flow into the joint 1 through the overflow hole, the inner cavity of the basin, the drainage hole of the basin outlet, the drainage hole 2211 on the support ring 221, and the groove 2111 on the inner ring 211 in sequence, and finally be discharged through the outlet 12 of the joint 1 through the drain pipe 6 to prevent the water in the basin from overflowing into the room.

[0035] In one embodiment, if Figure 2 , 8 As shown in Figure 9, in order to prevent the odor in the sewer from entering the room through the drain pipe 6, an anti-odor mechanism 3 is further provided between the water outlet 12 and the drain pipe 6, and the anti-odor mechanism 3 includes a cylinder body 31, a sealing portion 32 and a connecting pipe 33; the cylinder body 31 includes an outer cylinder 311 and an inner cylinder 312, and an inlet 3111 and an outlet 3112 are provided at both ends of the outer cylinder 311, and the inner side of the inlet 3111 is fixedly connected to the inner cylinder 312 extending toward the outlet 3112 and being necked, and the small diameter end of the inner cylinder 312 is a sealing port 3121, and threads are respectively provided at both ends of the outer cylinder 311, one end of the outer cylinder 311 close to the inner cylinder 312 is screwed to the water outlet 12, and the other end of the outer cylinder 311 is screwed to the connecting pipe 33, and the other end of the connecting pipe 33 is connected to the drain pipe 6. The sealing portion 32 includes a support 321 and a sliding portion 322. The support 321 is located in the outer cylinder 311 and close to the outlet 3112. The bottom of the support 321 is embedded in the inner cavity of the connecting tube 33. The sliding portion 322 is located in the outer cylinder 311 and between the inner cylinder 312 and the support 321. The support 321 includes an annular seat sleeve 3211 and a socket 3212 with a socket located in the middle of the seat sleeve 3211. The socket opening of the socket 3212 faces the inner cylinder 312. The socket 3212 is connected to the seat sleeve 3211 through a support rod 3213. Multiple support rods 3213 are distributed along the circumference of the socket 3212, and a water flow channel 3214 is formed between two adjacent support rods 3213.

[0036] like Figure 2 As shown, the sliding part 322 includes a sliding part body 3221 and a sealing ring 3222. The sealing ring 3222 is arranged on the outer edge of the sliding part body 3221. The sealing ring 3222 is sealed and adapted to the sealing port 3121. A sliding rod 3223 adapted to the socket is provided on the side of the sliding part body 3221 close to the support 321. The sliding rod 3223 can slide along the axial direction of the socket, that is, the sliding part 322 can slide between the inner cylinder 312 and the support 321. The end of the sliding rod 3223 and the bottom end of the socket are respectively provided with magnets with the same polarity facing each other.

[0037] like Figure 2 , 9As shown, when no water flows out of the basin, magnets are respectively provided at the end of the slide rod 3223 and the bottom end of the socket, and the two magnets have the same polarity opposite to each other. The two magnets with the same polarity opposite to each other generate a repulsive magnetic force, pushing the sliding part 322 to the left side onto the inner cylinder 312, that is, the sealing ring 3222 of the sliding part 322 is sealed and abutted against the sealing port 3121 on the inner cylinder 312 under the action of the magnetic force, thereby sealing the channel of the water outlet 12, which can effectively prevent the foul air in the sewer from entering the room. When water flows out of the wash basin from the drain pipe 5, the pressure and impact of the water overcome the magnetic force of the magnet with the same polarity opposite to it, and push the sliding part 322 to the right, that is, the sliding part 322 is away from the sealing port 3121 of the inner cylinder 312, and the sealing ring 3222 is separated from the sealing port 3121 on the inner cylinder 312 to form a gap, and the water flows into the inner cavity of the outer cylinder 311 through the gap between the sealing ring 3222 and the sealing port 3121, and then enters the connecting pipe 33 from the water flow channel 3214 on the support 321, and finally is discharged into the sewer through the drain pipe 6. When no water flows into the wash basin, under the magnetic force of the magnet with the same polarity opposite to it, the sliding part 322 is driven to move toward the sealing port 3121 of the inner cylinder 312, and the sealing ring 3222 and the sealing port 3121 are sealed against each other.

[0038] like Figure 3 , 8 As shown, in this embodiment, a plurality of spaced-apart supporting legs 3215 are provided at the bottom of the seat cover 3211 along the circumferential direction, and the supporting legs 3215 are clamped in the connecting tube 33 .

[0039] like Figure 2 As shown, in one embodiment, the outer cylinder 311 is expanded in diameter from the joint 1 to the connecting pipe 33. This structure is more convenient for sealing between the sliding part 322 and the inner cylinder 312 and for smooth drainage of water.

[0040] like Figure 2 As shown, the water outlet 12 of this embodiment includes a lower water outlet 121 and a side water outlet 122. The lower water outlet 121 is located at the bottom of the joint and is coaxially arranged with the water inlet 11. The side water outlet 122 is located at the side of the joint. The axis of the side water outlet 122 is perpendicular to the axis of the water inlet 11. One of the lower water outlet 121 or the side water outlet 122 is threadedly connected to the sealing cover 4. In this way, the drain pipe 6 can be connected to one of the lower water outlet 121 or the side water outlet 122 according to the space and actual needs, and the other is sealed and connected to the sealing cover 4, so that the outlet direction of the drain pipe 6 can be adjusted according to the space size and implementation needs for easy installation.

[0041] The cylinder 31, the sealing portion 32 and the connecting pipe 33 of the present embodiment are all made of engineering plastics, which will not affect the magnetic force of the opposite-sex magnets.

[0042] In order to facilitate observation of the working condition of the deodorizing mechanism 3 and timely understanding of any problems, the cylinder 31 is made of transparent engineering plastics.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
