Description

Technical Field

[0001] This utility model relates to the field of oil tank conveying pipe technology, and in particular to a sealing joint for oil tank conveying pipelines. Background Technology

[0002] Currently, in the oil and gas industry, the connection between pipelines and sealing joints mainly relies on two common technologies: threaded connection or flange connection.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Most existing connection methods between oil pipelines and sealing joints adopt threaded connections or flange connections. Threaded connections require the threaded part of the pipeline to be precisely screwed into the threaded hole of the joint, which consumes a lot of time. On the other hand, although flange connections are more reliable in some cases, their installation and disassembly processes are equally complex and time-consuming. Flange connections require two flanges to be tightly fixed together with bolts, which not only requires the use of a large number of bolts and nuts, but also requires ensuring that the tightness of each bolt is consistent to prevent leakage or damage caused by uneven force. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that most of the existing oil pipelines and sealing joints are connected by threaded connections or flange connections, which are relatively cumbersome to install and disassemble. Therefore, we propose a sealing joint for oil tank pipelines.

[0005] To achieve the above objectives, this application adopts the following technical solution: a sealing joint for an oil tank conveying pipeline, comprising a pipeline body: a joint body is slidably connected to one side of the pipeline body, a connecting plate is fixedly connected to one side of the joint body, a plurality of hollow blocks are fixedly connected to the surface of the connecting plate, and a snap-fit ​​groove is provided at both ends of the inner cavity of the hollow block; a cavity block is fixedly connected to the surface of the pipeline body, and a movable groove is provided at both ends of the cavity block; a toggle block is slidably connected inside the movable groove; a connecting plate is fixedly connected to one end of the toggle block; and a snap-fit ​​block is fixedly connected to one end of the connecting plate.

[0006] Preferably, the surface of the snap-fit ​​block is slidably connected to the interior of the snap-fit ​​groove, and the outer diameter of the snap-fit ​​block is adapted to the inner diameter of the snap-fit ​​groove.

[0007] Preferably, a return spring is fixedly connected to one end of the connecting plate, and one end of the return spring is fixedly connected to the interior of the hollow block.

[0008] Preferably, the top and bottom of the cavity block are provided with guide grooves, and the top and bottom of the connecting plate are fixedly connected with guide blocks, and the surface of the guide blocks is slidably connected to the inside of the guide grooves.

[0009] Preferably, a positioning block is fixedly connected to one side of the connector body, and a positioning groove is provided on one side of the pipe body, with the surface of the positioning block slidingly connected to the interior of the positioning groove.

[0010] Preferably, a sealing gasket is fixedly connected to one side of the connector body.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this utility model, the operator moves the actuating block, which in turn moves the connecting plate, causing the connecting plate to move the snap-fit ​​block. At this time, the snap-fit ​​block will disengage from the snap-fit ​​groove, thereby releasing the connection plate from the pipe body and allowing the connector body to be disassembled from the pipe body. The operation is convenient and quick, greatly saving the operator's working time and improving work efficiency. Attached Figure Description

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0020] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a sealing joint for an oil tank conveying pipeline, including a pipeline body 1; a joint body 2 is slidably connected to one side of the pipeline body 1, a connecting plate 3 is fixedly connected to one side of the joint body 2, a plurality of hollow blocks 4 are fixedly connected to the surface of the connecting plate 3, and a snap-fit ​​groove 5 is opened at both ends of the inner cavity of the hollow block 4; a cavity block 6 is fixedly connected to the surface of the pipeline body 1, and a movable groove 7 is opened at both ends of the cavity block 6; a toggle block 8 is slidably connected inside the movable groove 7; a connecting plate 9 is fixedly connected to one end of the toggle block 8; and a snap-fit ​​block 10 is fixedly connected to one end of the connecting plate 9. By moving the toggle block 8, the operator moves the connecting plate 9, which in turn moves the snap-fit ​​block 10. At this time, the snap-fit ​​block 10 will disengage from the inside of the snap-fit ​​groove 5, thereby releasing the connection plate 3 from the pipeline body 1, and thus allowing the joint body 2 to be disassembled from the pipeline body 1. The operation is convenient and quick, greatly saving the operator's working time and improving work efficiency.

[0021] Reference Figure 2 and Figure 4 As shown in this embodiment: the surface of the snap-fit ​​block 10 is slidably connected to the inside of the snap-fit ​​groove 5, and the outer diameter of the snap-fit ​​block 10 is adapted to the inner diameter of the snap-fit ​​groove 5. Through the slidable connection between the snap-fit ​​block 10 and the snap-fit ​​groove 5, the connection between the connecting plate 3 and the pipe body 1 is stably fixed. At the same time, since the outer diameter of the snap-fit ​​block 10 is adapted to the inner diameter of the snap-fit ​​groove 5, the stability of the connection is further enhanced, avoiding loosening during use, thereby ensuring the normal operation of the oil tank conveying pipeline and improving the conveying efficiency.

[0022] Reference Figure 4 As shown in this embodiment: a return spring 13 is fixedly connected to one end of the connecting plate 9, and one end of the return spring 13 is fixedly connected to the inside of the hollow block 4. By setting the return spring 13, when the worker disassembles the connector body 2, the elastic potential energy of the return spring 13 will drive the connecting plate 9 and the snap-fit ​​block 10 to reset, so that the snap-fit ​​block 10 is snapped back into the snap-fit ​​groove 5, thereby facilitating the worker to carry out the next installation work. The worker does not need to manually snap the snap-fit ​​block 10 into the snap-fit ​​groove 5, which further saves the worker's working time and improves work efficiency.

[0023] Reference Figure 4As shown in this embodiment: guide grooves 11 are provided at the top and bottom of the cavity of the cavity block 6, and guide blocks 12 are fixedly connected to the top and bottom of the connecting plate 9. The surface of the guide block 12 is slidably connected to the inside of the guide groove 11. By setting the guide groove 11 and the guide block 12, when the connecting plate 9 drives the snap-fit ​​block 10 to move, the guide block 12 will slide inside the guide groove 11, thereby guiding and limiting the movement direction of the connecting plate 9, avoiding the connection plate 9 from deviating during the movement, thus ensuring that the snap-fit ​​block 10 can be accurately snapped into the inside of the snap-fit ​​groove 5, further improving the stability of the connection.

[0024] Reference Figure 2 and Figure 3 As shown in this embodiment: a positioning block 15 is fixedly connected to one side of the connector body 2, and a positioning groove 14 is provided on one side of the pipe body 1. The surface of the positioning block 15 is slidably connected to the inside of the positioning groove 14. By setting the positioning block 15 and the positioning groove 14, when the connector body 2 is connected to the pipe body 1, the positioning block 15 will first slide into the inside of the positioning groove 14, thereby initially positioning the position of the connector body 2, so that the subsequent snap-fit ​​work can be carried out smoothly, avoiding misalignment during installation, and further improving the convenience and stability of installation.

[0025] Reference Figure 2 As shown in this embodiment, a sealing gasket 16 is fixedly connected to one side of the connector body 2. By setting the sealing gasket 16, when the connector body 2 is tightly connected to the pipe body 1, the sealing gasket 16 can effectively fill the tiny gap between the two, thereby enhancing the sealing performance of the connector and preventing leakage during the oil tank transportation process.

[0026] Working Principle: By moving the actuating block 8, the operator moves the connecting plate 9, which in turn moves the locking block 10. The locking block 10 then disengages from the locking groove 5, releasing the connection between the connecting plate 3 and the pipe body 1. This allows for the disassembly of the connector body 2 from the pipe body 1. The operation is convenient and quick, significantly saving operator time and improving efficiency. The sliding connection between the locking block 10 and the locking groove 5 ensures stable fixation between the connecting plate 3 and the pipe body 1. Furthermore, the matching outer diameter of the locking block 10 with the inner diameter of the locking groove 5 further enhances the connection's stability, preventing loosening during use and ensuring the normal operation of the oil tanker pipeline, thus improving transport efficiency. A return spring 13 is provided; after the operator disassembles the connector body 2, its elastic potential energy causes the connecting plate 9 and the locking block 10 to reset, allowing the locking block 10 to re-engage into the locking groove 5. This facilitates the next installation without requiring manual repositioning. Block 10 is inserted into the snap-fit ​​groove 5, further saving workers' time and improving work efficiency. By setting guide groove 11 and guide block 12, when the connecting plate 9 moves the snap-fit ​​block 10, the guide block 12 will slide inside the guide groove 11, thereby guiding and limiting the movement direction of the connecting plate 9, avoiding the connection plate 9 from deviating during movement, thus ensuring that the snap-fit ​​block 10 can be accurately inserted into the snap-fit ​​groove 5, further improving the stability of the connection. By setting positioning block 15 and positioning groove 14, when the connector body 2 is connected to the pipe body 1, the positioning block 15 will first slide into the positioning groove 14, thereby initially positioning the position of the connector body 2, so that the subsequent snap-fit ​​work can be carried out smoothly, avoiding misalignment during installation, and further improving the convenience and stability of installation. By setting sealing gasket 16, when the connector body 2 and the pipe body 1 are tightly connected, the sealing gasket 16 can effectively fill the small gap between the two, thereby enhancing the sealing performance of the joint and preventing leakage during oil tank transportation.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
