Description

Technical Field

[0001] This application relates to the field of pipe connection technology, and more specifically, to a pipe assembly that is easy to assemble and disassemble. Background Technology

[0002] In the existing system, pipe connections use plug-in connectors, with the male and female connectors located on opposite sides. After the male / female connectors are plugged in, they are locked together by snap rings to achieve a sealed connection.

[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: When installing or disassembling pipes, since the male / female connector has a certain overlap stroke, it is necessary to pull one side of the pipe apart. When the pipe is in a narrow area, there is not enough space to make it impossible to pull it apart, which makes the installation and disassembly process of the pipe cumbersome and increases the workload of maintenance.

The first pressing section at least partially abuts against the first pipe and the outer shell, or abuts against the second pipe and the outer shell.

[0014] Optionally, the locking member further includes a second pressing section located on the peripheral wall of the housing. When the locking member is removed, the peripheral wall of the housing can deform the first pressing section toward the outside of the housing through the second pressing section, so as to disengage from the second through portion.

[0035] This application provides a pipe assembly that is easy to assemble and disassemble, enabling pipe maintenance in confined spaces. The operation is simple and convenient, improving the efficiency of pipe maintenance.

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.

[0038] Please see Figure 1 and Figure 2 This is one embodiment of the pipe assembly in this application. The pipe assembly includes a first pipe 1, a second pipe 2, a housing 3, and a locking member 4. The first pipe 1 and the second pipe 2 can both be integrated with the pipeline. The first pipe 1 and the second pipe 2 are hollow cylindrical and have the same inner diameter. The second pipe 2 is connected to the first pipe 1. The housing 3 is movably disposed on the periphery of the first pipe 1 and can switch between a first position and a second position along the axial direction of the first pipe 1 to connect or disconnect the first pipe 1 and the second pipe 2. The locking member 4 is used to lock the first pipe 1 and the housing 3, and to lock the second pipe 2 and the housing 3, so that the first pipe 1 and the second pipe 2 are fixed relative to the housing 3, thereby achieving relative fixation of the first pipe 1 and the second pipe 2 and preventing the first pipe 1 from separating from the second pipe 2.

[0039] Please see Figures 3 to 5 In this embodiment, when the outer casing 3 is in the first position, the end of the outer casing 3 near the second pipe 2 is in the same plane as the end of the first pipe 1 near the second pipe 2. After the first pipe 1 and the second pipe 2 are connected, the outer casing 3 moves from the first position to the second position along the axial direction of the first pipe 1. When the outer casing 3 is in the second position, a part of the outer casing 3 is fitted onto the circumferential wall of the first pipe 1, and another part is fitted onto the circumferential wall of the second pipe 2. The first pipe 1 and the second pipe 2 are connected, and the outer casing 3 is sealed to both the first pipe 1 and the second pipe 2. That is, when the outer casing 3 is in the second position, it can connect the first pipe 1 and the second pipe 2, thus achieving the connection between the first pipe 1 and the second pipe 2. When the outer casing 3 moves from the second position to the first position along the axial direction of the first pipe 1, the end of the outer casing 3 near the second pipe 2 is in the same plane as the end of the first pipe 1 near the second pipe 2. The second pipe 2 is completely detached from the outer casing 3, and the second pipe 2 is disconnected from the first pipe 1, thus achieving the disassembly of the first pipe 1 and the second pipe 2.

[0040] Please see Figure 1 and Figure 5 To fix the first pipe 1 and the second pipe 2 relative to the outer casing 3, at least two locking elements 4 are provided, each located at one end of the outer casing 3. When the outer casing 3 is in the second position, at least one locking element 4 locks the outer casing 3 and the first pipe 1, and at least one locking element 4 locks the outer casing 3 and the second pipe 2. It is understood that by moving the outer casing 3 to switch it from the first position to the second position, the outer casing 3 is fitted onto the connection between the first pipe 1 and the second pipe 2, allowing the outer casing 3 to connect the first pipe 1 and the second pipe 2. Then, by operating at least one locking element 4 to lock the outer casing 3 and the first pipe 1, and at least one locking element 4 to lock the outer casing 3 and the second pipe 2, the first pipe 1 and the second pipe 2 are fixed relative to the outer casing 3, thus achieving relative fixation of the first pipe 1 and the second pipe 2, allowing the first pipe 1 and the second pipe 2 to conduct electricity, thereby achieving pipe connection. When it is necessary to disconnect the first pipe 1 and the second pipe 2, the locking element 4 is operated... The fastener 4 releases the locking between the outer casing 3 and the first pipe 1 and the second pipe 2, allowing the first pipe 1 and the second pipe 2 to move relative to the outer casing 3. Then, the outer casing 3 is moved from the second position to the first position along the axial direction of the first pipe 1, causing the second pipe 2 to disengage from the outer casing 3, thereby disconnecting the first pipe 1 and the second pipe 2. The pipe assembly provided in this application can achieve the connection and disconnection between the first pipe 1 and the second pipe 2 by sliding the outer casing 3. When installing or disassembling the pipe, it is not necessary to pry open one side of the pipe, enabling pipe maintenance in a confined space. The operation is simple and convenient, requiring no special tools and requiring less professional skills from workers, thus improving the efficiency of pipe maintenance.

[0041] As another optional implementation in this embodiment, the outer casing 3 is movably disposed on the periphery of the second pipe 2, and its position can switch between a first position and a second position along the axial direction of the second pipe 2, for connecting or disconnecting the first pipe 1 and the second pipe 2. This embodiment differs only in the placement position of the outer casing 3, but the implementation principle of the outer casing 3, the first pipe 1, and the second pipe 2 is the same. Therefore, the specific implementation process of this embodiment will not be described in detail.

[0042] Please see Figure 5To ensure the sealing effect of the pipe assembly, the pipe assembly also includes multiple sealing rings 9, which are respectively disposed on the peripheral walls of the first pipe 1 and the second pipe 2. When the outer shell 3 is in the second position, a seal is formed between the sealing rings 9 and the inner wall of the outer shell 3. In this embodiment, two sealing rings 9 are arranged parallel to each other on the peripheral wall of the first pipe 1 to double seal the gap between the first pipe 1 and the outer shell 3. Two sealing rings 9 are arranged parallel to each other on the peripheral wall of the second pipe 2 to double seal the gap between the second pipe 2 and the outer shell 3 when the outer shell 3 is in the second position. The double sealing makes the sealing reliability between the first pipe 1 and the outer shell 3, and between the second pipe 2 and the outer shell 3, high, applicable to both high and low pressure scenarios, thus expanding the application scenarios of the pipe assembly.

[0043] Please see Figure 6 One of the inner walls of the first pipe 1 and the second pipe 2 is provided with a guide slope 7, which is used to connect the first pipe 1 and the second pipe 2. In this embodiment, the guide slope 7 is provided on the inner wall of the second pipe 2 as an example. The guide slope 7 is located in the end edge region of the second pipe 2 near the first pipe 1. The guide slope 7 is tapered and gradually narrows away from the first pipe 1. The guide slope 7 is designed to reduce the possible positional deviation of the first pipe 1 and the second pipe 2 during assembly. It can be understood that when the first pipe 1 approaches the second pipe 2, due to possible slight misalignment, the first pipe 1 does not move strictly along the axis of the second pipe 2. At this time, the guide slope 7 will first contact the surface of the first pipe 1 and generate a certain amount of lateral thrust, which helps the first pipe 1 to readjust its insertion path, making the subsequent part of the first pipe 1 closer to the ideal straight trajectory. With the setting of the guide slope 7, even if the initial alignment of the first pipe 1 and the second pipe 2 is not perfect, the guide slope 7 can gradually correct the relative displacement between the first pipe 1 and the second pipe 2.

[0044] Furthermore, to enhance the sealing between the first pipe 1 and the second pipe 2 after docking, one of the inner walls of the first pipe 1 and the second pipe 2 is provided with a guide slope 7, and the other is provided with a sealing element 8. When the first pipe 1 and the second pipe 2 dock, the guide slope 7 compresses the sealing element 8 to seal the first pipe 1 and the second pipe 2. In this embodiment, the sealing element 8 is provided on the periphery of the first pipe 1 and the guide slope 7 is provided on the inner wall of the second pipe 2 as an example. The sealing element 8 is placed at the end of the first pipe 1 facing the second pipe 2 and is used to fill the gap between the first pipe 1 and the second pipe 2. The sealing element 8 can adapt to certain thermal expansion and contraction changes, and not only has good compression and rebound performance, but also can maintain a stable shape under long-term working conditions. To facilitate the installation of the seal 8, a clearance groove is provided on the periphery of the first pipe 1, and the seal 8 is located in the clearance groove. It can be understood that the guide slope 7 serves a guiding function on the one hand, and on the other hand, when the first pipe 1 approaches the second pipe 2, the guide slope 7 presses against the seal 8 to compress the seal 8, so that the seal 8 prevents fluid from leaking from the gap between the first pipe 1 and the second pipe 2, thereby achieving a sealing effect between the first pipe 1 and the second pipe 2 after docking.

[0045] In order to achieve locking between the outer shell 3 and the first pipe 1 and between the outer shell 3 and the second pipe 2, the outer shell 3 is provided with at least two first through parts 5 on its peripheral wall, and the first pipe 1 and the second pipe 2 are respectively provided with second through parts 6. When the outer shell 3 is in the second position, the first through parts 5 and the second through parts 6 are connected and correspondingly arranged, and the locking member 4 passes through the first through parts 5 and the second through parts 6 at the same time to restrict the displacement between the first pipe 1 and the outer shell 3, and at the same time restrict the displacement between the second pipe 2 and the outer shell 3, so that the first pipe 1 and the second pipe 2 are fixed relative to the outer shell 3.

[0046] In some embodiments, please refer to Figure 1 and Figure 2 The locking member 4 includes a first pressing section 41 and a second pressing section 42, which are connected and integrally formed. In this embodiment, the first pressing section 41 is vertically arranged, and the second pressing section 42 is horizontally arranged, with the first pressing section 41 and the second pressing section 42 being perpendicular to each other. In this embodiment, the first through section 5 is arc-shaped along the periphery of the outer shell 3, and both the first pipe 1 and the second pipe 2 are provided with a second through section 6, which is arranged along the periphery of the first pipe 1 or the second pipe 2. The locking member 4 is preferably a snap ring. Two sets of the first pressing section 41 and the second pressing section 42 are provided, with the first pressing section 41 connected away from the second pressing section 42. Under the action of force, the two first pressing sections 41 can deform to move away from each other, and after the force is released, the two first pressing sections 41 can return to their original position.

[0047] When the outer casing 3 is in the second position, the first pressing section 41 simultaneously passes through the first through portion 5 and the second through portion 6. The first pressing section 41 at least partially abuts against the first pipe 1 and the outer casing 3, or simultaneously abuts against the second pipe 2 and the outer casing 3. The first pressing section 41 restricts the tendency of the first pipe 1 and the second pipe 2 to move along the axial direction of the outer casing 3, so that the first pipe 1 and the outer casing 3 are relatively fixed, and the second pipe 2 and the outer casing 3 are relatively fixed. The second pressing section 42 is located on the peripheral wall of the outer casing 3. When the locking member 4 is withdrawn, the peripheral wall of the outer casing 3 can deform the outer side of the outer casing 3 described by the first pressing section 41 through the second pressing section 42, so as to disengage from the second through portion 6. At this time, the locking member 4 can release the abutment against the first pipe 1, or release the abutment against the second pipe 2, realizing the movable connection between the first pipe 1 and the outer casing 3, or the second pipe 2 and the outer casing 3.

[0048] The outer casing 3 has a limiting groove 31 on its peripheral wall, which corresponds to the locking member 4. The limiting groove 31 communicates with the first through part 5. When the second pressing section 42 is located in the limiting groove 31, it keeps the first pressing section 41 and the second through part 6 from disengaging. The setting of the second pressing section 42 in the limiting groove 31 can keep the second pressing section 42 relatively stable, avoid relative sliding between the arc surface of the peripheral wall of the outer casing 3 and the second pressing section 42, and keep the first pressing section 41 and the second through part 6 from disengaging. Furthermore, the limiting groove 31 has a guide slope 32 and a limiting surface 33. The guide slope 32 is used to connect with the peripheral wall of the outer casing 3 so that the locking member 4 can slide into or out of the limiting groove 31. The limiting surface 33 can limit the second pressing part in the direction of withdrawal of the locking member 4, prevent the second pressing section 42 from disengaging from the outer casing 3, and facilitate the operation of the locking member 4 to lock again.

[0049] It should be emphasized that in this embodiment, the second through portion 6 is arranged in a ring shape, and the first pressing section 41 passes through both the first through portion 5 and the second through portion 6. The first pipe 1 and the second pipe 2 are rotatably engaged with the outer casing 3. Because the second through portion 6 is arranged in a ring shape, and the first pressing section 41 passes through both the first through portion 5 and the second through portion 6, the first pressing section 41 can slide relative to the ring-shaped through portion. That is, the first pipe 1 and the second pipe 2 can rotate relative to the outer casing 3, which is suitable for application scenarios where the first pipe 1 and the second pipe 2 need to rotate.

[0050] As another optional embodiment of the above embodiments, please refer to Figures 7 to 9The first through-part 5 and the second through-part 6 are provided in a hole-like manner, and the locking member 4 is configured as a fastening bolt. When the outer shell 3 is in the second position, the fastening bolt passes through the first through-part 5 and the second through-part 6 to fix the first pipe 1 and the second pipe 2 to the outer shell 3. In this embodiment, there are two first through-parts 5 along the length direction of the outer shell 3, and there are also two corresponding locking members 4. The first through-parts 5 and the second through-part 6 are the same size and shape, and the first through-parts 5 and the second through-part 6 have internal threads. When the first pipe 1 and the second pipe 2 are connected, the distance between the two first through-parts 5 is equal to the distance between the two second through-parts 6. When the outer shell 3 is in the second position, the first through-parts 5 and the second through-parts 6 are provided in a one-to-one correspondence, and the central axis of the first through-part 5 coincides with the central axis of the second through-part 6. The two fastening bolts pass through the first through-parts 5 and the second through-part 6 to lock the outer shell 3 to the first pipe 1 and the second pipe 2, and prevent the outer shell 3 from separating from the first pipe 1 and the second pipe 2.

[0051] It is particularly important to emphasize that when the outer casing 3 is in the second position, since the locking member 4 passes through the first through part 5 and the second through part 6 at the same time, it fixes the first pipe 1 and the second pipe 2 to the outer casing 3 simultaneously. On the one hand, it enhances the connection stability between the outer casing 3 and the first pipe 1 and the second pipe 2, reducing the probability of the first pipe 1 and the second pipe 2 becoming detached. On the other hand, the fastener restricts the tendency of the first pipe 1 and the second pipe 2 to rotate circumferentially relative to the outer casing 3, so that the first pipe 1, the outer casing 3 and the second pipe 2 cannot rotate relative to each other, thus achieving the function of locking and fastening. This is suitable for usage scenarios where the first pipe 1 and the second pipe 2 are relatively fixed.

[0052] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. 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.
