Description

Technical Field

[0001] This utility model relates to the field of four-way technology, and in particular to a three-dimensional four-way with replaceable branch pipes. Background Technology

[0002] When constructing sewage drainage pipes in indoor sanitary buildings, it is usually necessary to connect two horizontal drainage pipes into the same riser through a four-way connector. Existing four-way connectors, as shown in patent application number CN201621027610.1, include a main riser and a branch pipe fixedly connected to the side of the main riser. The branch pipe and the main riser cannot be separated. During use, the drainage pipe and the branch pipe are heat-fused together, and the drainage pipe and the branch pipe are basically inseparable, which makes it inconvenient to repair and replace the drainage pipe in subsequent use. Utility Model Content

[0003] To address the shortcomings of existing four-way branch pipes that cannot be separated from the main riser, which makes maintenance and replacement of drainage pipes inconvenient, this utility model proposes a four-way branch pipe that can be separated from the main riser, facilitating maintenance and replacement of drainage pipes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A three-dimensional four-way connector with replaceable branch pipes includes a main riser, a connector, a gasket, and a branch pipe. The connector includes a connecting pipe, a first flange, a second flange, a first baffle, and a limiting block. One end of the connecting pipe is fixedly connected to the side of the main riser, and the other end of the connecting pipe is fixedly connected to an outwardly extending first flange along its circumference. The gasket is attached to the side of the first flange away from the main riser. A second flange extending away from the main riser is fixedly connected to the outer circumference of the first flange. Multiple first baffles are fixedly connected to the inner circumference of the second flange. The inner side of the first baffle is provided with... The branch pipe has an arc surface, and a first groove is formed between the first baffle and the gasket. A limiting block is fixedly connected to one end of the first groove. The branch pipe includes a branch pipe body and a plurality of first clips fixedly connected to one end of the branch pipe body along its outer periphery. One end of the branch pipe body abuts against the gasket, and its outer periphery fits against the inner arc surface of the first baffle. The width of the first clip is less than the distance between two adjacent first baffles. The first clip is set in the first groove and abuts against the limiting block. The side of the first clip away from the limiting block is flush with the end of the inner arc surface of the first baffle.

[0005] With the above setup, firstly, the branch pipe can be detachably connected to the main riser via a connector, facilitating maintenance and replacement of the drainage pipe; secondly, the branch pipe and connector are easy and quick to connect and disconnect; and thirdly, the connection between the branch pipe and connector is secure, and it is easy to determine whether the installation is in place.

[0006] Furthermore, the branch pipe also includes a plurality of second clamps fixedly connected to the end of the branch pipe body along its outer periphery, and the connector also includes a plurality of second baffles fixedly connected to the inner periphery of the second flange. The plurality of second baffles are spaced apart from the plurality of first baffles. A second groove is formed between the second baffle and the gasket. The second clamp is engaged in the second groove. The inner side of the second baffle is provided with a straight surface tangent to the outer surface of the branch pipe body. A first clearance opening is formed between the first baffle and the second baffle adjacent on one side to avoid the first clamp. A second clearance opening is formed between the first baffle and the second baffle adjacent on the other side to avoid the second clamp.

[0007] The above settings further enhance the stability of the branch pipe connection.

[0008] Furthermore, the center of the second card is close to the middle of the second baffle.

[0009] Furthermore, the first baffle has an inclined surface at the end away from the limiting block. One end of the inclined surface extends to the arc surface, and the other end of the inclined surface is inclined away from the limiting block and extends to the inner wall of the second flange.

[0010] The above settings enhance the connection strength between the first baffle and the second flange.

[0011] Furthermore, a mark is provided on the side of the second baffle away from the main riser, and the mark is flush with one side of the second clip.

[0012] The above settings further ensure that the branch pipes are installed in place.

[0013] Furthermore, the inner side of the branch pipe body near the main riser, the inner side of the gasket, and the inner side of the connecting pipe are flush with each other.

[0014] The above settings help reduce four-way noise.

[0015] Furthermore, the upper end of the main riser is provided with an external thread, and the inner circumference of the upper end of the main riser is provided with a first conical surface. The lower side of the first conical surface is recessed and is provided with an upward-facing support surface. The four-way valve also includes a locking cap, a retaining ring, and a sealing ring. The locking cap is provided with an internal thread, and the inner side of the locking cap is provided with a downward-extending annular protrusion. A downward-opening groove is formed between the annular protrusion and the internal thread.

[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] like Figures 1 to 4 A three-dimensional four-way connector with replaceable branch pipes includes a main riser 3, a connector, a gasket 4, and a branch pipe 5. The connector includes a connecting pipe 6, a first flange 7, a second flange 8, a first baffle 9, and a limiting block 10. One end of the connecting pipe 6 is fixedly connected to the side of the main riser 3, and the other end of the connecting pipe 6 is fixedly connected to an outwardly extending first flange 7 along its circumference. The gasket 4 is attached to the side of the first flange 7 away from the main riser 3. A second flange 8 extending away from the main riser 3 is fixedly connected to the outer circumference of the first flange 7. Multiple first baffles 9 are fixedly connected to the inner circumference of the second flange 8. The inner side of the first baffle 9 is provided with an arc surface. A first slot 11 is formed between the first baffle 9 and the gasket 4. The limiting block 10 is fixedly connected to one end of the first slot 11. The branch pipe 5 includes a branch pipe body 51 and a plurality of first clips 52 fixedly connected to one end of the branch pipe body 51 along its outer periphery. One end of the branch pipe body 51 abuts against the gasket 4, and its outer periphery fits against the inner arc surface of the first baffle 9. The width of the first clip 52 is less than the distance between two adjacent first baffles 9. The first clip 52 is disposed in the first slot 11 and abuts against the limiting block 10. The side of the first clip 52 away from the limiting block 10 is flush with the end of the inner arc surface of the first baffle 9.

[0023] With the above settings, firstly, the branch pipe 5 is detachably connected to the main riser 3 via a connector, which facilitates the maintenance and replacement of the drainage pipe; secondly, the connection between the branch pipe 5 and the connector is quick and easy to make and break; and thirdly, the connection between the branch pipe 5 and the connector is firm, and it is easy to determine whether the installation is in place.

[0024] Specifically, the main riser 3 is basically a circular pipe structure with an flared upper end for easy acceptance of fittings, and a lower end serving as a plug for insertion into the vertical sewage riser. Two connectors are provided, with their axes on the same horizontal plane and both vertically connected to the side of the main riser 3. Each connector can be detachably connected to a branch pipe 5. The end of the branch pipe 5 furthest from the main riser 3 is provided with a threaded or other interface for easy threaded or heat-fused connection to a horizontal drainage pipe. The four-way connector of this application is specifically equipped with two first baffles 9, located on the upper and lower sides of the second flange 8. When installing the branch pipe 5, the end of the branch pipe 5 closest to the first clamp 52... Align the connector and push in the branch pipe 5. The first clamping plate passes by the side of the first baffle 9 and fits against the gasket 4. The end of the branch pipe body 51 fits against the gasket 4. The gasket 4 is specifically a rubber gasket 4, ensuring the seal between the branch pipe body 51 and the connecting pipe 6 to prevent water leakage. Then, keeping the main riser 3 stationary, rotate the branch pipe 5. The branch pipe 5 rotates around its own axis, causing the first clamping member 52 to rotate into the first clamping groove 11 until the first clamping member 52 abuts against the limiting block 10. At this time, the first flange 7 and the branch pipe body 51 clamp the gasket 4, and the first baffle 9 abuts against the back of the first clamping plate to prevent the branch pipe 5 from detaching. And at this time, if Figure 4 Workers can visually ensure that the side of the first clamp 52 furthest from the limiting block 10 is flush with the end of the inner arc surface of the first baffle 9 furthest from the limiting block 10, thus ensuring proper connection. That is, if the worker sees the first clamp 52 protruding outside the first clamping groove 11, it indicates that the branch pipe 5 has not been tightened properly and needs to be rotated further, or check whether there are foreign objects in the first clamping groove 11 that are jamming the first clamp 52, until the branch pipe 5 is installed properly. When the drain pipe is blocked, the branch pipe 5 can be rotated in the opposite direction to remove it from the connector, and the drain pipe can be cleared through the branch pipe 5. After clearing, the branch pipe 5 can be reconnected to the connector. When the drain pipe is damaged and needs to be replaced, the branch pipe 5 can be rotated in the opposite direction to remove it from the connector. The drain pipe can be replaced separately or replaced with a new branch pipe 5 and the drain pipe together, and then the branch pipe 5 can be reconnected to the connector. It is not necessary to replace the main riser 3, which shortens the construction period and reduces construction costs.

[0025] As one implementation, the branch pipe 5 also includes a plurality of second clamps 53 fixedly connected to the end of the branch pipe body 51 along its outer periphery. The connector also includes a plurality of second baffles 12 fixedly connected to the inner periphery of the second flange 8. The plurality of second baffles 12 are spaced apart from the plurality of first baffles 9. A second groove 13 is formed between the second baffles 12 and the gasket 4. The second clamps 53 are engaged in the second groove 13. The inner side of the second baffles 12 is provided with a straight surface tangent to the outer surface of the branch pipe body 51. A first clearance opening 14 is formed between the first baffle 9 and the second baffle 12 adjacent on one side to avoid the first clamps 52. A second clearance opening 15 is formed between the first baffle 9 and the second baffle 12 adjacent on the other side to avoid the second clamps 53.

[0026] The above settings further enhance the stability of the branch pipe 5 connection.

[0027] Specifically, the four-way connector of this application is provided with two second baffles 12, which are respectively located on the left and right sides of the second flange 8, as shown below. Figure 4 The limiting block 10 is located at the clockwise end of the first slot 11. The first clearance opening 14 is formed between the first baffle 9 and the second baffle 12 adjacent to the counterclockwise side. The second clearance opening 15 is formed between the first baffle 9 and the second baffle 12 adjacent to the clockwise side. When installing the branch pipe 5, the first locking piece 52 passes through the first clearance opening 14 and abuts against the gasket 4. The second locking piece 53 passes through the second clearance opening 15 and abuts against the gasket 4. When the branch pipe 5 is rotated clockwise, the first locking piece 52 is inserted into the first slot 11 and abuts against the limiting block 10. The second locking piece 53 is inserted into the second slot 13. The back of the second baffle 12 abuts against the back of the second locking piece 53. The straight surface of the inner side of the second baffle 12 abuts against the left and right sides of the branch pipe body 51, thereby improving the reliability of the connection of the branch pipe 5.

[0028] As one implementation, the center of the second card 53 is close to the middle of the second baffle 12.

[0029] Specifically, such as Figure 4 The outer sides of the first clip 52 and the second clip 53 are arc-shaped and fit against the inner side of the second flange 8, further improving the stability of the branch pipe 5. The line connecting the center of the second clip 53 to the center of the branch pipe body 51 passes through the midpoint of the straight surface inside the second baffle 12. At this time, the second clip 53 is basically fitted in the middle of the second baffle 12. The contact area between the second clip 53 and the second baffle 12 is as large as possible to improve the pull-out resistance of the branch pipe 5.

[0030] As one implementation, the first baffle 9 is provided with an inclined surface 16 at the end away from the limiting block 10. One end of the inclined surface 16 extends to the arc surface, and the other end of the inclined surface 16 is inclined away from the limiting block 10 and extends to the inner wall of the second flange 8.

[0031] The above settings enhance the connection strength between the first baffle 9 and the second flange 8.

[0032] As one implementation, a mark 17 is provided on the side of the second baffle 12 away from the main riser 3, and the mark 17 is flush with one side of the second clip 53.

[0033] The above settings further ensure that branch pipe 5 is installed in place.

[0034] When branch pipe 5 is installed in place, if Figure 4 When one side of the second baffle 12 is flush with the mark 17, it is determined that the branch pipe 5 is tightened in place.

[0035] As one implementation method, the inner side of the branch pipe body 51 near the main riser 3, the inner side of the gasket 4, and the inner side of the connecting pipe 6 are flush with each other.

[0036] The above settings help reduce four-way noise.

[0037] like Figure 3 The inner sides of the connecting pipe 6, gasket 4, and branch pipe 5 are flush, forming a flat drainage surface. The water flow is less disturbed and the noise is less.

[0038] As one implementation, the upper end of the main riser 3 is provided with an external thread 18, and the inner circumference of the upper end of the main riser 3 is provided with a first conical surface 19. The lower side of the first conical surface 19 is recessed and is provided with an upward-facing support surface 20. The four-way valve also includes a locking cap 21, a retaining ring 22 and a sealing ring 23. The locking cap 21 is provided with an internal thread 24, and the inner side of the locking cap 21 is provided with a downward-extending annular protrusion 25. A downward-opening groove 26 is formed between the annular protrusion 25 and the internal thread 24. The outer circumference of the retaining ring 22 is provided with a second conical surface 27 that fits with the first conical surface 19. One side of the retaining ring 22 is provided with a retractable notch 28. The locking cap 21 is tightened to the upper end of the main riser 3 by the internal thread 24 and the external thread 18. The upper end of the main riser 3 is embedded in the groove 26. The annular protrusion 25 pushes the retaining ring 22 downward, and the retaining ring 22 and the support surface 20 clamp the sealing ring 23.

[0039] The above settings facilitate the connection of external pipes.

[0040] The locking cover 21 of this application is specifically a circular structure. The inner diameter of the locking cover 21 is larger than the pipe to be installed. When installing the pipe, first insert the sealing ring 23 downward into the upper end of the main riser 3, and then insert the retaining ring 22 into the upper end of the main riser 3. The pipe passes through the locking cover 21 and is inserted downward into the upper end of the main riser 3, and passes through the retaining ring 22. The lower end of the pipe and the support surface 20 clamp the sealing ring 23 to prevent water leakage. Tighten the locking cover 21 downward. The upper end of the main riser 3 is embedded in the groove 26. The annular protrusion 25 pushes the retaining ring 22 downward. The retaining ring 22 shrinks under the pressure of the first conical surface 19, and the notch 28 contracts. Finally, the inner side of the retaining ring 22 clamps the outer side of the pipe to prevent the pipe from being pulled out.

[0041] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
