Description

Technical Field

[0001] This utility model relates to the field of water conveyance equipment technology, and more specifically, to a quick-installation structure for a water conveyance pipeline. Background Technology

[0002] In practical applications, in order to improve the utilization rate of water resources, branch pipes are often connected to the main water supply pipeline. The branch pipe can be a rigid water pipe or a flexible pipe. The water source is diverted from the main water supply pipeline to the branch pipe. In the existing technology, the connection of the branch pipe usually involves opening a through hole on the main water supply pipeline, fixing the internal threaded base into the through hole, and connecting the branch pipe fitting to the base by thread.

[0003] However, threaded connections require tools to tighten and often need to be sealed with PTFE tape, which is cumbersome, time-consuming, and inefficient. Furthermore, the threads can rust and stick together over time, causing inconvenience for later maintenance. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a quick-installation structure for water transmission pipelines, which uses interface components to fix and install branch pipeline connectors, which is simple to operate and ensures the stability and sealing of the connection, and is convenient to use.

[0005] The technical solution adopted by this utility model is to provide a quick-installation structure for a water transmission pipeline. The water transmission pipeline includes a main transmission pipeline, and the main transmission pipeline has a through hole in its pipe wall. The quick-installation structure is fixedly connected to the through hole of the main transmission pipeline. The quick-installation structure includes:

[0006] An interface assembly includes an annular inner cylinder and a connecting ring extending and protruding around the annular inner cylinder. The connecting ring is fixedly connected to the annular inner cylinder. One end of the annular inner cylinder extends into the through hole of the main pipeline, and the other end extends out of the main pipeline. The connecting ring is fixedly connected to the outer surface of the pipe wall of the main pipeline. A limiting structure is provided on the inner wall of the annular inner cylinder. The limiting structure includes a snap-fit ​​groove, which is located at the end of the annular inner cylinder that extends into the main pipeline.

[0007] A branch pipe connector includes a connector body, a plug-in part, and a fixing part. The fixing part is provided with a protrusion, and a snap-fit ​​protrusion is provided at one end of the protrusion near the plug-in part. The plug-in part of the branch pipe connector is inserted into the annular inner cylinder, and the branch pipe connector is rotated so that the snap-fit ​​protrusion is axially snapped into the snap-fit ​​groove.

[0008] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: By setting a limiting structure on the inner wall of the annular inner cylinder, and setting a snap-fit ​​groove on the limiting structure, and setting a snap-fit ​​protrusion on the branch pipe connector, when the branch pipe connector is inserted into the annular inner cylinder, the branch pipe connector is rotated to make the snap-fit ​​protrusion engage axially with the snap-fit ​​groove, thereby realizing the fixed connection between the branch pipe connector and the main pipeline. The operation is simple and the connection is firm. During use, the branch pipe connector and the main pipeline can be disassembled and assembled as needed.

[0009] In an optional embodiment, the limiting structure is provided with a first check slope, which is located on one side of the snap-fit ​​groove. A second check slope is provided on the protrusion at a position opposite to the first check slope, which is located on one side of the snap-fit ​​protrusion. The second check slope is adapted to the first check slope.

[0010] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: after the branch pipe connector is fixedly connected to the main pipeline through the interface component, the first check slope on the limiting structure and the second check slope on the protrusion abut against each other, which can prevent the interface component and the branch pipe connector from rotating, avoid the branch pipe connector from becoming loose, and improve the stability of the branch pipe connector connection.

[0011] In an optional embodiment, the limiting structure is provided with two first guide slopes, the first guide slopes being located on the side of the first check slope away from the snap-fit ​​groove, and the protrusion is provided with two second guide slopes, the second guide slopes being located on the side of the second check slope away from the snap-fit ​​protrusion, and the first guide slopes cooperating with the second guide slopes.

[0012] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting the first guide slope and the second guide slope, the snap-fit ​​protrusion on the branch pipe fitting can be more easily snapped into the snap-fit ​​groove, which is more labor-saving.

[0013] In an optional embodiment, the annular inner cylinder is provided with at least one positioning element near the end where the connecting ring is connected to the main pipeline.

[0014] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: By setting the positioning component on the annular inner cylinder, positioning can be performed during installation to ensure that the positioning component is parallel to the cross-section of the main pipeline, thereby ensuring that the outlet of the branch pipeline is perpendicular to the main pipeline, ensuring more accurate installation position of the branch pipeline connector, and avoiding deviation in the installation position of the branch pipeline connector.

[0015] In an optional embodiment, the end of the connecting ring that connects to the main pipeline is provided with multiple sealing protrusions.

[0016] Compared with existing technologies, the technical effect achieved by adopting this technical solution is as follows: by setting a sealing protrusion on the connecting ring, the sealing performance between the interface component and the main pipeline after fixed installation can be increased.

[0017] In an optional embodiment, the branch pipe fitting further includes a sealing part disposed between the connector body and the plug-in part. The end of the sealing part near the connector body is configured as an annular sealing platform, and the diameter of the annular sealing platform is larger than that of the plug-in part.

[0018] Compared with existing technologies, the technical effect achieved by adopting this technical solution is: by setting an annular sealing platform, the sealing performance of the branch pipe fittings and interface components after connection is improved.

[0019] In an optional embodiment, the end of the sealing portion away from the connector body is configured as an inwardly inclined portion, which is configured as an elastic structure. When the interface assembly is connected to the branch pipe connector, the inclined portion abuts against the upper end of the annular inner cylinder.

[0020] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting an inclined part, and the inclined part is set as an elastic structure and abuts against the upper end of the annular inner cylinder, the sealing performance of the branch pipe fitting and interface assembly after connection is further improved, effectively preventing water leakage.

[0021] In an optional embodiment, the connecting ring is fixedly connected to the inner surface of the main pipeline wall.

[0022] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the connecting ring can be fixedly connected to both the inner wall and the outer wall of the main pipeline, further improving the applicability of the interface components.

[0023] In an optional embodiment, the connecting ring is connected to the main pipeline by ultrasonic welding, laser welding or high-frequency welding.

[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are: ultrasonic welding, laser welding, or high-frequency welding between the connecting ring and the main pipeline improves the reliability of the connection between the interface component and the main pipeline.

[0025] In an optional embodiment, the branch pipe fitting is one or more of a tee pipe, an elbow pipe, a tee valve, and an elbow valve.

[0026] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: branch pipe fittings can be selected from one or more types of tees, elbows, tee valves, and elbow valves, improving the applicability of water supply pipelines and allowing for the selection of branch pipe fittings according to different needs.

[0027] The beneficial effects of this utility model are as follows:

[0028] (1) By setting a limiting structure on the inner wall of the annular inner cylinder, a snap-fit ​​groove is set on the limiting structure, and a snap-fit ​​protrusion is set on the branch pipe connector, when the branch pipe connector is inserted into the annular inner cylinder, the branch pipe connector is rotated so that the snap-fit ​​protrusion snaps into the snap-fit ​​groove, thereby realizing the fixed connection between the branch pipe connector and the main pipeline. The operation is simple and the connection is firm.

[0029] (2) By the first check slope on the limiting structure and the second check slope on the protrusion abutting against each other, the rotation between the interface component and the branch pipe connector can be prevented, the branch pipe connector can be prevented from loosening, and the stability of the branch pipe connector connection can be improved.

[0030] (3) By setting the first guide slope and the second guide slope, the snap-fit ​​protrusion on the branch pipe fitting can be more easily snapped into the snap-fit ​​groove, which saves more effort.

[0031] (4) By setting an annular sealing platform and an inclined part, and the inclined part is set as an elastic structure and abuts against the upper end of the annular inner cylinder, the sealing performance of the branch pipe fitting and the interface assembly is further improved, and the leakage is effectively prevented.

[0032] (5) The connecting ring can be fixedly connected to the inner wall of the main pipeline or the outer wall of the main pipeline, further improving the applicability of the interface component. Attached Figure Description

[0046] See appendix Figure 1 To be continued Figure 5 As shown, this utility model provides a quick-installation structure for a water transmission pipeline. The water transmission pipeline includes a main transmission pipeline 100, and a through hole is provided on the pipe wall of the main transmission pipeline 100. The quick-installation structure is fixedly connected to the through hole of the main transmission pipeline 100. The quick-installation structure includes:

[0047] Interface assembly 200 includes an annular inner cylinder 210 and a connecting ring 220 extending and protruding around the annular inner cylinder 210. The connecting ring 220 is fixedly connected to the annular inner cylinder 210. One end of the annular inner cylinder 210 extends into the through hole of the main transmission pipeline 100, and the other end extends out of the main transmission pipeline 100. The connecting ring 220 is fixedly connected to the outer surface of the pipe wall of the main transmission pipeline 100. A limiting structure 211 is provided on the inner wall of the annular inner cylinder 210. The limiting structure 211 includes a snap-fit ​​groove 2111, which is provided at the end of the annular inner cylinder 210 that extends into the main transmission pipeline 100.

[0048] The branch pipe connector 300 includes a connector body 310, a plug part 320, and a fixing part 330. The fixing part 330 is provided with a protrusion 331. The end of the protrusion 331 near the plug part 320 is provided with a snap-fit ​​protrusion 3311. The plug part 320 of the branch pipe connector 300 is inserted into the annular inner cylinder 210. Rotating the branch pipe connector 300 causes the snap-fit ​​protrusion 3311 to be axially snapped into the snap-fit ​​groove 2111.

[0049] Specifically, the connecting ring 220 and the annular inner cylinder 210 can be integrally fixedly connected, and the connector body 310, the insertion part 320 and the fixing part 330 are also integrally fixedly connected.

[0050] Specifically, the number of limiting structures 211 and protrusions 331 is at least two.

[0051] Preferably, the connection between the connecting ring 220 and the main pipeline 100 includes, but is not limited to, ultrasonic welding, laser welding, and high-frequency welding.

[0052] Specifically, the interface component 200 is installed and fixed on the main transmission pipeline 100. One end of the annular inner cylinder 210 extends into the through hole of the main transmission pipeline 100, and the other end extends out of the through hole of the main transmission pipeline 100. The connecting ring 220 is welded to the outer surface of the pipe wall of the main transmission pipeline 100 by ultrasonic welding or laser welding. Two symmetrically distributed limiting structures 211 are provided on the inner wall of the annular inner cylinder 210. The bottom surface of the limiting structure 211 is provided with a snap-fit ​​groove 2111. The snap-fit ​​groove is located at the end of the annular inner cylinder 210 that extends into the main transmission pipeline 100.

[0053] Specifically, when the branch pipe connector 300 is fixedly installed with the interface assembly 200, the protrusion 331 and the limiting structure 211 are inserted downwards at a 90° angle. When the two protrusions 331 extend out of the annular inner cylinder 210, the connector body 310 is rotated 90°, thereby causing the two protrusions 331 to rotate. At this time, the snap-fit ​​protrusions 3311 on the protrusions 331 can be snapped into the snap-fit ​​grooves 2111 in the limiting structure 211, thereby realizing the fixed installation of the branch pipe connector 300. The operation is simple and the connection is firm. During use, the branch pipe connector 300 and the main pipeline 100 can be disassembled and assembled as needed.

[0054] See appendix Figure 3 and attached Figure 4 In an optional embodiment, the limiting structure 211 is provided with a first anti-return slope 2112, which is located on one side of the snap-fit ​​groove 2111. The protrusion 331 is provided with a second anti-return slope 3312 at a position opposite to the first anti-return slope 2112, which is located on one side of the snap-fit ​​protrusion 3311. The second anti-return slope 3312 is adapted to the first anti-return slope 2112.

[0055] Specifically, there are two first check slopes 2112, which include a first check slope one and a first check slope two. The first check slope one and the first check slope two are respectively disposed on both sides of the snap-fit ​​groove 2111. There are two second check slopes 3312, which include a second check slope one and a second check slope two. The second check slope one and the second check slope two are respectively disposed on both sides of the snap-fit ​​protrusion 3311. The first check slope one and the second check slope one are adapted to each other, and the first check slope two and the second check slope two are adapted to each other.

[0056] Specifically, after the branch pipe connector 300 is fixedly connected to the main pipeline 100 through the interface assembly 200, the first check slope 2112 on the limiting structure 211 and the second check slope 3312 on the protrusion 331 abut against each other, which can prevent the interface assembly 200 and the branch pipe connector 300 from rotating, avoid the branch pipe connector 300 from becoming loose, and improve the stability of the connection of the branch pipe connector 300.

[0057] See appendix Figure 3 and attached Figure 4In an optional embodiment, the limiting structure 211 is provided with a first guide slope 2113, which is located on the side of the first check slope 2112 away from the snap-fit ​​groove 2111. The protrusion 331 is provided with a second guide slope 3313, which is located on the side of the second check slope 3312 away from the snap-fit ​​protrusion 3311. The first guide slope 2113 and the second guide slope 3313 cooperate with each other.

[0058] Specifically, the number of first guide slopes 2113 is set to two, and the number of second guide slopes 3313 is set to two. By setting the first guide slopes 2113 and the second guide slopes 3313, the snap-fit ​​protrusions 3311 on the branch pipe fitting 300 can more easily snap into the snap-fit ​​grooves 2111, which saves more effort and greatly reduces the installation intensity during installation.

[0059] See appendix Figure 2 and attached Figure 3 In an optional embodiment, the annular inner cylinder 210 is provided with at least one positioning element 212 near the end of the connecting ring 220 that is connected to the main pipeline 100.

[0060] Specifically, the positioning element 212 can be configured as a recessed platform. Preferably, there are two recessed platforms, symmetrically arranged at one end of the annular inner cylinder 210.

[0061] Specifically, the recessed platform is set at one end of the annular inner cylinder 210 near the snap-fit ​​groove 2111. By setting the recessed platform on the annular inner cylinder 210, positioning can be performed during installation to ensure that the positioning part 212 is parallel to the cross section of the main pipeline 100, thereby ensuring that the outlet of the branch pipeline is perpendicular to the main pipeline 100, ensuring that the installation position of the branch pipeline connector 300 is more accurate, and avoiding the offset of the installation position of the branch pipeline connector 300.

[0062] See appendix Figure 3 In an optional embodiment, the end of the connecting ring 220 that is connected to the main pipeline 100 is provided with a plurality of sealing protrusions 221.

[0063] Specifically, by providing a sealing protrusion 221 on the connecting ring 220, the sealing performance between the interface assembly 200 and the main pipeline 100 after fixed installation can be increased.

[0064] See appendix Figure 4 and attached Figure 5 In an optional embodiment, the branch pipe fitting 300 further includes a sealing part 340, which is disposed between the fitting body 310 and the plug-in part 320. The end of the sealing part 340 near the fitting body 310 is configured as an annular sealing platform 341, and the diameter of the annular sealing platform 341 is larger than that of the plug-in part 320.

[0065] In an optional embodiment, the end of the sealing part 340 away from the connector body 310 is configured as an inwardly inclined part 342. The inclined part 342 is configured as an elastic structure. When the interface assembly 200 is connected to the branch pipe connector 300, the inclined part 342 abuts against the upper end of the annular inner cylinder 210.

[0066] Specifically, by setting an inclined part 342, and the inclined part 342 being an elastic structure that abuts against the upper end of the annular inner cylinder 210, the sealing performance of the branch pipe fitting 300 after being connected to the interface assembly 200 is further improved, effectively preventing water leakage.

[0067] See appendix Figure 6 and attached Figure 7 In an optional embodiment, the connecting ring 220 is fixedly connected to the inner surface of the pipe wall of the main pipeline 100.

[0068] Specifically, in another embodiment, the connecting ring 220 is installed in reverse and is fixedly connected to the inner surface of the main pipeline 100 wall. That is, the connecting ring 220 is welded to the inner wall of the main pipeline 100 by laser welding or ultrasonic welding. At this time, the limiting structure 211 is still set at one end of the annular inner cylinder 210 that extends into the main pipeline 100, and the positioning member 212 is set at one end of the annular inner cylinder 210 that extends out of the main pipeline 100. The branch pipeline connector 300 is the same as in the previous embodiment. It is only necessary to rotate the branch pipeline connector 300 to rotate the snap-fit ​​protrusion 3311 on the branch pipeline connector 300 into the snap-fit ​​groove 2111 on the limiting structure 211, thereby fixing the branch pipeline connector 300 and the interface assembly 200.

[0069] In an optional embodiment, the branch pipe fitting 300 is one or more of a tee pipe, an elbow pipe, a tee valve, and an elbow valve.

[0070] Specifically, the branch pipe fitting 300 can be selected from one or more of the following: tee pipe, elbow pipe, tee valve, and elbow valve, to improve the applicability of the water supply pipeline. The branch pipe fitting 300 can be selected according to different needs.

[0071] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
