The top end of the insertion ring abuts against the blocking part. The side of the insertion ring facing the positioning ring is provided with a sealing groove. A sealing rubber ring is sleeved in the sealing groove to seal the connection between the positioning ring and the insertion ring. The positioning ring has at least three limiting plates snapped into its middle. Each limiting plate includes a snap-fit ​​part, a mounting groove, and a fixing part. The mounting groove and the limiting part snap into each other to position and install the positioning ring and the limiting plates. A compression ring is fixedly connected to the inner wall of the limiting plate, and a pressure bearing ring is fixedly connected to the side of the sealing rubber ring facing the compression ring. After the compression ring applies force to the pressure bearing ring, it is used to control the deformation of the sealing rubber ring and to compensate and seal the gap at the connection of the two drain pipe bodies.

[0005] Preferably, the limiting plate has an arc-shaped structure, and the limiting plates are combined to form a ring structure, which is used to install the ring formed by the limiting plates into the middle of the positioning ring.

[0006] Preferably, after the two drain pipe bodies are inserted into each other, the compression ring is fixedly connected to the limiting plate to connect the limiting plate into a whole.

[0007] Preferably, the limiting part is a hook-shaped structure, the limiting part is engaged in the middle of the mounting groove, the engaging part is located between the limiting part and the blocking part, and the outer wall of the sealing rubber ring abuts against the engaging part to limit the deformation direction of the sealing rubber ring.

[0008] Preferably, the fixing part is located on the outer wall of the limiting part, and the middle thread of the fixing part is connected to a compression bolt. The top end of the compression bolt abuts against the outer wall of the limiting part to fix the limiting plate and the positioning ring.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] See Figures 1-5 The present invention provides a municipal drainage and sewage pipe fitting, including a drainage pipe body 1. Positioning rings 2 and insertion rings 3 are fixedly connected to both ends of the drainage pipe body 1 respectively. The insertion rings 3 are inserted into the positioning rings 2 for positioning and installing the two drainage pipe bodies 1. The fixed connection method can also be welding, riveting, screwing or gluing. A support ring 4 is fixedly connected to the outer wall of the drain pipe body 1. The outer wall of the support ring 4 and the outer wall of the positioning ring 2 are on the same horizontal plane. This ensures that after installation, the two ends of the drain pipe bodies 1 are at the same height, enhancing the stability of the drain pipe bodies 1 during installation and use, preventing deformation or damage to the drain pipe bodies 1 due to ground settlement or other factors, and avoiding any impact on the sealing of the connection between the two drain pipe bodies 1.

[0020] The positioning ring 2 includes an inclined portion 21, a blocking portion 22, and a limiting portion 23. The top end of the insertion ring 3 abuts against the blocking portion 22. The side of the insertion ring 3 facing the positioning ring 2 has a sealing groove 5, and a sealing rubber ring 6 is fitted inside the sealing groove 5 to seal the connection between the positioning ring 2 and the insertion ring 3. At least three limiting plates 7 are snapped into the middle of the positioning ring 2. Each limiting plate 7 includes a snapping portion 71, an installation groove 72, and a fixing portion 73. The installation groove 72 and the limiting portion 23 are snapped into each other to position and install the positioning ring 2 and the limiting plates 7. The limiting plates 7 have an arc-shaped structure, and they are combined to form a circular structure to install the circular structure formed by the limiting plates 7 into the middle of the positioning ring 2. Before the two drain pipe bodies 1 are inserted, the limiting plates 7 are first placed in the middle of the positioning ring 2 so that the limiting plates 7 form a circular structure, thus positioning and connecting the limiting plates 7 and the positioning ring 2.

[0021] Depend on Figure 3As shown, a compression ring 8 is fixedly connected to the inner wall of the limiting plate 7. A sealing rubber ring 6 is fitted into the sealing groove 5 of the insertion ring 3. After the two drainage pipe bodies 1 are inserted into each other, the compression ring 8 is fixedly connected to the limiting plate 7 to connect the limiting plate 7 into a whole. The compression ring 8 can also limit the two inserted drainage pipe bodies 1 to each other, so as to prevent the two inserted drainage pipe bodies 1 from separating after geological settlement.

[0022] The side wall of the plug ring 3 is inclined. After the two drain pipe bodies 1 are plugged into each other, the plug ring 3 and the inclined part 21 form a connecting groove 12. A sealing ring is glued and fixed at the connecting groove 12 to increase the sealing performance of the connection between the two drain pipe bodies 1. The connecting groove 12 can position the installation of the sealing ring. The sealing ring and the sealing rubber ring 6 work together to ensure the sealing performance after the two drain pipe bodies 1 are connected.

[0023] A pressure-bearing ring 10 is fixedly connected to the side of the sealing rubber ring 6 facing the compression ring 8. After the compression ring 8 applies force to the pressure-bearing ring 10, it is used to control the deformation of the sealing rubber ring 6 and to compensate for the gap at the connection of the two drain pipe bodies 1. At least four compression protrusions 9 are fixedly connected to the side of the compression ring 8 facing the sealing rubber ring 6. The sidewall of the compression protrusion 9 is arc-shaped. A guide block 11 is fixedly connected to the side of the pressure ring 10 facing the compression ring 8. The number of guide blocks 11 is the same as the number of compression protrusions 9. The side of the guide block 11 facing the compression protrusion 9 is inclined, which is used to guide the movement of the compression protrusion 9 and to compress and deform the sealing rubber ring 6. After the two drain pipe bodies 1 are connected, the limiting plate 7 and the compression ring 8 are rotated. The compression ring 8 compresses the guide block 11 through the compression protrusion 9, thereby pushing the pressure ring 10 to compress the sealing rubber ring 6, so that the sealing rubber ring 6 is under stress, ensuring the sealing of the connection between the two drain pipe bodies 1. When a gap appears at the connection between the two drain pipe bodies 1, the sealing rubber ring 6 will deform to a certain extent to fill the gap.

[0024] The limiting part 23 has a hook-shaped structure and is snapped into the middle of the mounting groove 72. The snap-fit ​​part 71 is located between the limiting part 23 and the blocking part 22. The outer wall of the sealing rubber ring 6 abuts against the snap-fit ​​part 71 to limit the deformation direction of the sealing rubber ring 6. The fixing part 73 is located on the outer wall of the limiting part 23. A compression bolt is threaded into the middle of the fixing part 73. The top of the compression bolt abuts against the outer wall of the limiting part 23 to fix the limiting plate 7 and the positioning ring 2. After the two drain pipe bodies 1 are inserted into each other, the limiting plate 7 limits the deformation direction of the sealing rubber ring 6, ensuring that the sealing rubber ring 6 deforms in the expected direction during the compression process, improving the sealing effect, and thus ensuring the sealing performance after the two drain pipe bodies 1 are inserted. By threading the compression bolt and abutting the top of the compression bolt against the outer wall of the limiting part 23, a firm connection between the limiting plate 7 and the positioning ring 2 is achieved, preventing the limiting plate 7 from shifting during use and ensuring stable fit between the various components of the pipe fitting.

[0025] When the main body 1 of the drain pipe is inserted, the limiting plate 7 and the positioning ring 2 need to be installed first, and then the insertion ring 3 is inserted into the middle of the positioning ring 2. At this time, the compression ring 8 is fixedly connected to the limiting plate 7, and all the limiting plates 7 are connected into a whole. After the limiting plate 7 and the compression ring 8 are rotated, the sealing rubber ring 6 is compressed. At this time, the limiting plate 7 and the positioning ring 2 are fixedly connected by the compression bolt.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
