[0008] The second pipe is connected to the first pipe;

[0009] A connector is slidably disposed within the first pipe along its axial direction to switch between a first position and a second position. A limiting block is provided on the outer peripheral wall of the connector. When the connector is in the first position, the entire connector is located inside the first pipe. When the connector is in the second position, both ends of the connector are located inside both the first pipe and the second pipe, and the connector is sealed to both the first pipe and the second pipe. The limiting block is fixed relative to the limiting part.

[0010] When the connector is in the second position, the locking member passes through the second pipe and abuts against the connector to lock the second pipe and the connector.

[0011] Optionally, the first pipe is provided with a guide groove in the axial direction, and the limiting block is slidably disposed in the guide groove; the connector is provided with a handle and a fastener, the handle is disposed on the outer peripheral wall of the first pipe, and one end of the fastener passes through the handle and the guide groove and is fixedly connected to the limiting block.

[0012] Optionally, the limiting part is disposed at one end of the guide groove near the second pipe, and the limiting part and the end of the guide groove near the second pipe surround each other to form a limiting groove; when the connector is in the second position, the limiting block is located in the limiting groove and is engaged with the limiting part.

[0013] Optionally, the first pipe is further provided with a connecting groove, one opening of which faces the guide groove and communicates with the guide groove, and the other opening of which faces the second pipe.

[0014] Optionally, the second pipe is provided with a first locking groove for accommodating the locking member, and the peripheral wall of the connector is provided with a second locking groove;

[0015] When the connector is in the second position, the orthographic projection of the first lock groove coincides with the orthographic projection of the second lock groove, the locking member passes through the first lock groove, and the locking member is at least partially located in the second lock groove and engaged with the inner wall of the second lock groove.

[0017] When the connector is in the second position, the locking block is located in the slot, the locking member passes through both the first locking slot and the slot, and the locking member abuts against the locking block.

[0018] Optionally, the pipe joint further includes a dustproof component, which is used to cover the gap between the first pipe and the second pipe.

When the connector is in the second position, one end of the connector is inserted into the second pipe, meaning both ends of the connector are simultaneously within the first and second pipes. At this point, the limiting block moves with the connector to the limiting part, and the limiting block and the limiting part are relatively fixed to lock the connector to the first pipe. Then, the locking member passes through the second pipe and abuts against the connector to lock the second pipe and the connector, thereby achieving the connection of the first pipe... The connection between the first and second pipes prevents the first and second pipes from becoming detached, thus improving the reliability of the pipe fitting assembly. When it is necessary to disassemble the first and second pipes, simply remove the locking part and slide the connecting part along the axial direction of the first pipe to release the fixation between the limiting part and the limiting block, so that the connecting part can move from the second position to the first position, thereby achieving the disconnection between the first and second pipes. The pipe fitting assembly provided in this application does not require special tools during pipe installation or disassembly, has low requirements for workers' professional skills, and is simple and convenient to operate, improving the connection efficiency and maintenance efficiency of the pipes.

[0036] This application provides a pipeline connector assembly that is easy to maintain, making the assembly and disassembly of the connector assembly simple and convenient, and improving the connection efficiency and operation and maintenance efficiency of the pipeline.

It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0039] Please see Figures 1 to 3 This is one embodiment of a pipe fitting assembly that is easy to maintain, as described in this application. The pipe fitting assembly includes a first pipe 1, a second pipe 2, a connector 3, and a locking member 4.

[0040] Both the first pipe 1 and the second pipe 2 can be integrated with the pipeline. The first pipe 1 and the second pipe 2 are generally hollow cylindrical in shape, and the inner diameters of the first pipe 1 and the second pipe 2 are the same. The first pipe 1 and the second pipe 2 are connected together. The connector 3 is hollow cylindrical in shape and is slidably disposed inside the first pipe 1 along the axial direction of the first pipe 1 to switch between the first position and the second position, so as to realize the connection or disconnection between the first pipe 1 and the second pipe 2. In this embodiment, when it is necessary to connect the first pipe 1 and the second pipe 2, the first pipe 1 and the second pipe 2 are operated to align. When the connector 3 is in the first position, the entire connector 3 is located inside the first pipe 1. The connector 3 is operated to slide along the axial direction of the first pipe 1. As the connector 3 gradually moves from the first position to the second position, the end of the connector 3 near the second pipe 2 is gradually inserted into the second pipe 2 until the connector 3 moves to the second position. When the connector 3 is in the second position, both ends of the connector 3 are simultaneously located inside the first pipe 1 and the second pipe 2. The connector 3 is sealed to the first pipe 1 and the second pipe 2. The connector 3 can connect the first pipe 1 and the second pipe 2, so that the first pipe 1, the connector 3, and the second pipe 2 are internally connected, thereby realizing the pipe connection. When it is necessary to disconnect the first pipe 1 and the second pipe 2, the connector 3 is operated to slide along the axial direction of the first pipe 1, so that the connector 3 moves from the second position to the first position, thereby realizing the disconnection between the first pipe 1 and the second pipe 2.

[0041] In order to achieve the connection between the first pipe 1 and the connector 3, and the connection between the second pipe 2 and the connector 3, a limiting block 31 is provided on the outer peripheral wall of the connector 3; when the connector 3 is in the second position, both ends of the connector 3 are simultaneously located in the first pipe 1 and the second pipe 2, the limiting block 31 and the limiting part 11 are relatively fixed to lock the first pipe 1 and the connector 3, and the locking member 4 passes through the second pipe 2 and abuts against the connector 3 to lock the second pipe 2 and the connector 3. Understandably, when it is necessary to connect the first pipe 1 and the second pipe 2, the first pipe 1 and the second pipe 2 are aligned, and the connecting member 3 is slid along the axial direction of the first pipe 1, so that the connecting member 3 moves from the first position to the second position; when the connecting member 3 is in the second position, the limiting block 31 moves with the connecting member 3 to the limiting part 11, and the limiting block 31 and the limiting part 11 are relatively fixed to lock the connecting member 3 to the first pipe 1; then the locking member 4 is operated to pass through the second pipe 2 and abut against the connecting member 3 to lock the second pipe 2 and the connecting member 3, thereby realizing the connection between the first pipe 1 and the second pipe 2. The connection prevents the first pipe 1 and the second pipe 2 from separating, thus improving the reliability of the pipe joint assembly. When it is necessary to disassemble the first pipe 1 and the second pipe 2, simply remove the locking part 4 and operate the connecting part 3 to slide along the axial direction of the first pipe 1 to release the fixation between the limiting part 11 and the limiting block 31, so that the connecting part 3 can move from the second position to the first position, thereby realizing the disconnection between the first pipe 1 and the second pipe 2. The pipe joint assembly provided by this application does not require special tools during pipe installation or disassembly, has low requirements for workers' professional skills, and is simple and convenient to operate, improving the connection efficiency and operation and maintenance efficiency of the pipe.

[0042] Please see Figure 2 and Figure 3To facilitate the operation of the connector 3 within the first pipe 1 and the second pipe 2, the first pipe 1 is provided with a guide groove 12 along the axial direction, and a limiting block 31 is slidably disposed in the guide groove 12. The connector 3 is provided with a handle 32 and a fastener 33. The handle 32 is disposed on the outer peripheral wall of the first pipe 1, and one end of the fastener 33 passes through the handle 32 and the guide groove 12 and is fixedly connected to the limiting block 31. The handle 32 is fixed to the connector 3 by the fastener 33 and moves synchronously with the connector 3. In this embodiment, the handle 32 is semi-circular and surrounds the outer peripheral wall of the first pipe 1. Two guide grooves 12 are provided, and the two guide grooves 12 are centrally symmetrically arranged along the central axis of the first pipe 1. Two limiting blocks 31 are correspondingly provided, and the two limiting blocks 31 are axially symmetrically arranged along the central axis of the first pipe 1. During pipeline installation, the first pipe 1 and the second pipe 2 are connected. By pulling the handle 32, the fastener 33 and the limiting block 31 move along the guide groove 12, so that the connector 3 can move synchronously, allowing the connector 3 to quickly switch from the first position to the second position, thus connecting the first pipe 1 and the second pipe 2. During pipeline disassembly, the locking member 4 is released from the locking of the connector 3. By pulling the handle 32, the fastener 33 and the limiting block 31 move along the guide groove 12, so that the connector 3 moves synchronously, allowing the connector 3 to quickly switch from the second position to the first position, thus disconnecting the first pipe 1 and the second pipe 2.

[0043] Please see Figure 3 The limiting part 11 is disposed at one end of the guide groove 12 near the second pipe 2, and the limiting part 11 and the end of the guide groove 12 near the second pipe 2 enclose each other to form a limiting groove 13. When the connector 3 is in the second position, the limiting block 31 is located in the limiting groove 13 and is engaged with the limiting part 11. The handle 32 drives the limiting part 11 and the connector 3 to move along the guide groove 12. When the limiting part 11 moves toward the second pipe 2 assembly to the limiting groove 13, the connector 3 is in the second position, and the limiting block 31 and the limiting groove 13 are engaged to restrict the connector 3 from continuing to slide along the direction of the second pipe 2. At the same time, the limiting part 11 abuts against the limiting block 31 to prevent the connector 3 from rotating circumferentially, thereby achieving mutual locking between the first pipe 1 and the connector 3.

[0044] In this embodiment, when the handle 32 pulls the fastener 33 and the limiting block 31 to the leftmost end of the guide groove 12, the connector 3 is in the first position; when the handle 32 pulls the fastener 33 and the limiting block 31 to the limiting groove 13, the connector 3 is in the second position, facilitating precise adjustment of the connector 3. Furthermore, to facilitate the assembly of the connector 3, the first pipe 1 is also provided with a connecting groove 14. One opening of the connecting groove 14 faces the guide groove 12 and communicates with it, while the other opening of the connecting groove 14 faces the second pipe 2. In this embodiment, the connecting groove 14 has a first groove segment 141 and a second groove segment 142. The first groove segment 141 and the second groove segment 142 are perpendicular to each other. The first groove segment 141 connects the guide groove 12 and the second groove segment 142, and the second groove segment 142 allows the limiting block 31 to move towards the second pipe 2 to disengage from the first pipe 1. When the first pipe 1 is connected to the second pipe 2, the second pipe 2 blocks the opening of the second groove segment 142 that is not connected to the first groove segment 141, preventing the limiting block 31 from sliding out of the opening. It is understood that when the connector 3 needs to be assembled, one end of the connector 3 is fitted into the first pipe 1, and the limiting block 31 slides along the second groove segment 142 to the first groove segment 141, until it slides into the guide groove 12, thus fitting the connector 3 into the first pipe 1. When the connector 3 needs to be removed separately from the first pipe 1, the handle 32 drives the limiting block 31 to move along the guide groove 12, entering the first groove segment 141 through the opening connecting the first groove segment 141 and the guide groove 12, and then sliding along the first groove segment 141 and the second groove segment 142, sliding out from the opening of the second groove segment 142 that is not connected to the first groove segment 141, thereby separating the connector 3 from the first pipe 1.

[0045] Please continue reading. Figure 2 and Figure 3The second pipe 2 is provided with a first locking groove 21 for accommodating the locking member 4, and the peripheral wall of the connector 3 is provided with a second locking groove 34. When the connector 3 is in the second position, the orthographic projection of the first locking groove 21 coincides with the orthographic projection of the second locking groove 34. The locking member 4 passes through the first locking groove 21, and at least part of the locking member 4 is located within the second locking groove 34 and engaged with the inner wall of the second locking groove 34. In this embodiment, the first locking groove 21 is columnar and vertically arranged on the peripheral wall of the second pipe 2. There are two first locking grooves 21, and the two first locking grooves 21 are symmetrically arranged along the axis of the second pipe 2. The second locking groove 34 is annularly arranged on the peripheral wall of the connector 3. The locking member 4 is preferably a retaining spring, which has two connecting ends. When the connector 3 is in the second position, the connecting end of the locking member 4 passes through the first locking groove 21, and at least part of the locking member 4 is located in the second locking groove 34 and engaged with the inner wall of the second locking groove 34, thereby restricting the connector 3 from disengaging from the second pipe 2 along the length direction of the second pipe 2, and realizing the limiting of the connector 3 and the second pipe 2 along the length direction. It should be emphasized that, since the second locking groove 34 is annular, when the connector 3 is in the second position, rotating the first pipe 1 will cause the connector 3 and the first pipe 1 to rotate synchronously under the action of the fastener 33. The part of the locking member 4 inserted in the first locking groove 21 will slide relative to the second locking groove 34, that is, the first pipe 1 can rotate relative to the second pipe 2, which is suitable for application scenarios where the first pipe 1 and the second pipe 2 need to rotate.

[0046] Please see Figure 4In another embodiment, to suit the application scenario where the first pipe 1 and the second pipe 2 are relatively fixed, the connecting member 3 is provided with a locking block 35 on its peripheral wall. The second pipe 2 is provided with a first locking groove 21 for accommodating the locking member 4 and a locking groove 22 for accommodating the locking block 35. The locking groove 22 is provided corresponding to the first locking groove 21 and is connected to the first locking groove 21. When the connecting member 3 is in the second position, the locking block 35 is located in the locking groove 22. The locking member 4 passes through both the first locking groove 21 and the locking groove 22, and the locking member 4 abuts against the locking block 35 to prevent the connecting member 3 from disengaging from the second pipe 2. In this embodiment, the thickness of the locking block 35 is much smaller than the thickness of the limiting block 31. The locking block 35 is located on the side of the limiting block 31 closer to the second pipe 2. When the operating handle 32 moves the connecting member 3 toward the second position, the locking block 35 and the limiting block 31 move synchronously. When the connector 3 is in the second position, the locking block 35 is located in the slot 22. At this time, the locking member 4 is operated so that the locking member 4 passes through the first locking slot 21 and the slot 22 and abuts against the locking block 35. The cooperation between the locking member 4 and the locking block 35 restricts the movement of the connector 3 along the length of the second pipe 2, preventing the connector 3 from disengaging from the second pipe 2 along the length of the second pipe 2. At the same time, the cooperation between the slot 22 and the locking block 35 restricts the movement of the connector 3 along the circumferential direction, preventing the connector 3 from rotating relative to the second pipe 2 in the circumferential direction. Thus, the first pipe 1, the connector 3, and the second pipe 2 cannot rotate relative to each other, achieving the function of locking and fastening, which is suitable for the application scenario where the first pipe 1 and the second pipe 2 are relatively fixed.

[0047] Please see Figure 3 To ensure the sealing effect of the pipeline, the pipeline joint also includes multiple sealing rings 5. These sealing rings 5 ​​are respectively disposed on the inner walls of the first pipe 1 and the second pipe 2. When the connector 3 is in the second position, a seal is formed between the sealing rings 5 ​​and the peripheral wall of the connector 3. In this embodiment, two sealing rings 5 ​​are arranged parallel to each other on the inner wall of the first pipe 1 to double-seal the gap between the first pipe 1 and the connector 3. Similarly, two sealing rings 5 ​​are arranged parallel to each other on the inner wall of the second pipe 2 to double-seal the gap between the second pipe 2 and the connector 3 when the connector 3 is in the second position. This double sealing ensures high sealing reliability between the first pipe 1 and the connector 3, and between the second pipe 2 and the connector 3, making it suitable for both high and low pressure scenarios and expanding the application scenarios of the pipeline joint.

[0048] During prolonged use, dust easily accumulates on the surfaces of the first pipe 1 and the second pipe 2. Since the first pipe 1 and the second pipe 2 are separate entities, a gap exists at the connection point when they are joined. Dust falls from this connection point onto the surface of the connector 3 and then moves with the connector 3 into the interior of both pipes, contaminating the sealing ring 5 and potentially causing leaks. To address this issue, the pipe joint also includes a dustproof component 6. This component covers the gap between the first pipe 1 and the second pipe 2, allowing dust to settle on its surface and significantly reducing dust accumulation at the connection point.

[0049] For details, please refer to Figure 5 and Figure 6 In some embodiments, the dustproof component 6 is disposed around the connection between the first pipe 1 and the second pipe 2, and the inner wall of the dustproof component 6 seals against both the periphery of the first pipe 1 and the periphery of the second pipe 2. In this embodiment, the dustproof component 6 is preferably a dustproof sealing ring 5. By providing the dustproof sealing ring 5, on the one hand, the connection between the first pipe 1 and the second pipe 2 can be blocked to prevent dust from falling into the pipe joint; on the other hand, the dustproof sealing ring 5 achieves a seal between the first pipe 1 and the second pipe 2, further enhancing the sealing performance of the pipeline.

[0050] Please see Figure 7 In other embodiments, the dustproof component 6 is provided with a connector 61. The dustproof component 6 is arranged around one of the first pipe 1 and the second pipe 2, and the other of the first pipe 1 and the second pipe 2 is inserted into the connector 61. In this embodiment, the dustproof component 6 is arranged around the second pipe 2. The dustproof component 6 can be integrally formed with the second pipe 2, or it can be detachably fixedly connected to the second pipe 2. The connector 61 of the dustproof component 6 faces the first pipe 1, and the dustproof component 6 is flared. When the first pipe 1 and the second pipe 2 are connected, the second pipe 2 is inserted into the connector 61, and the dustproof component 6 can cover the connection between the first pipe 1 and the second pipe 2 to prevent dust.

[0051] Please see Figure 8In order to cover the gap between the first pipe 1 and the second pipe 2, in other embodiments, one of the first pipe 1 and the second pipe 2 is provided with a protrusion 15, and the other of the first pipe 1 and the second pipe 2 is provided with a recess 23. When the first pipe 1 and the second pipe 2 are connected, the protrusion 15 is inserted into the recess 23. In this embodiment, the first pipe 1 is provided with a protrusion 15, and the second pipe 2 is provided with a recess 23. It can be understood that the provision of the protrusion 15 and the recess 23 causes the first pipe 1 and the second pipe 2 to have a small misalignment. When the first pipe 1 and the second pipe 2 are connected, the protrusion 15 is inserted into the recess 23. Due to the presence of the protrusion 15, when dust falls from the connection between the first pipe 1 and the second pipe 2, it accumulates on the protrusion 15, thereby preventing dust from falling into the pipe joint.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
