Description

Technical Field

[0001] This utility model relates to the field of sealing joint technology, specifically a snap-fit ​​quick-connect valve sealing joint for pipelines. Background Technology

[0002] Valve sealing joints are components used to connect pipelines. They are usually made of durable materials such as stainless steel, aluminum alloy, or plastic, and are characterized by corrosion resistance and durability. They are suitable for various environments and working conditions and are commonly used for pipeline connections that transport liquids, gases, powders, and other media. They are widely used in petrochemical, food processing, agricultural irrigation, and other fields.

[0003] Most existing sealing joints are flange connections or threaded connections, which require workers to use various tools for installation. This is inconvenient, time-consuming, and labor-intensive, thus affecting work efficiency and making them difficult for workers to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a snap-fit ​​quick-connect valve sealing joint for pipelines, which solves the problem mentioned in the background that most existing sealing joints are flange connections or threaded connections, requiring workers to use various tools for installation, which is inconvenient, time-consuming, and labor-intensive, thus affecting work efficiency and making them difficult for workers to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a snap-fit ​​type quick-connect valve sealing joint for pipelines, including a first connecting seat, a first pipeline fixedly connected to the middle of the first connecting seat, mounting grooves on both sides of the first connecting seat, mounting seats fixedly connected to both sides of the first connecting seat, a rotating shaft rotatably connected to the inner side of the mounting seat, a connecting block fixedly connected to the surface of the rotating shaft, a fixing block fixedly connected to the top of the connecting block, an extension rod slidably connected to the inside of the fixing block, a pressure block fixedly connected to the bottom left end of the connecting block, a locking block fixedly connected to the right end of the connecting block, an installation cavity opened inside the first connecting seat, a sealing ring fixedly connected to the left end of the installation cavity, an installation block slidably connected to the inside of the installation cavity, a limit groove opened on the surface of the installation block, a second connecting seat fixedly connected to the right end of the installation block, and a second pipeline fixedly connected to the middle side of the second connecting seat.

[0006] Preferably, the diameter of the first pipe is the same as the inner wall diameter of the second pipe, and the right end of the first pipe extends to the inner wall of the second pipe and fits tightly against the inner wall of the second pipe.

[0007] Preferably, the mounting block is annular in shape, the diameter of the mounting block is the same as the inner wall diameter of the mounting cavity, and the length of the mounting block is 2 mm less than the length of the mounting cavity.

[0008] By adopting the above technical solution, and by setting up an installation block, a sealing ring, etc., in conjunction with a pressure block and a locking block, when the installation block is inserted into the installation cavity, the rotating connecting block drives the pressure block to rotate into the installation cavity and press against the left end of the limiting groove. As the operator applies force, the pressure block is forced through the limiting groove to push the installation block to squeeze the sealing ring, causing the sealing ring to change shape. This makes the right end of the second connecting seat fit with the first connecting seat. At this time, the sealing ring generates a reaction force to push the right side surface of the second connecting seat to fit tightly against the locking block, completing the installation. The operation is simple, easy to use, and improves work efficiency.

[0009] Preferably, the sealing ring is made of rubber, the sealing ring is 4 mm thick, and the right side of the sealing ring is tightly fitted with the left end of the second pipe and the mounting block.

[0010] Preferably, the limiting groove is annular in shape, the limiting groove is distributed on the middle side of the surface of the mounting block, and the position of the limiting groove corresponds to the position of the mounting groove.

[0011] Preferably, the extension rod is fitted to the inner wall of the fixing block, and the diameters at both ends of the extension rod are larger than the diameter at the middle of the extension rod.

[0012] By adopting the above technical solution, and by setting up extension rods and fixing blocks in combination, when the worker feels that it is difficult to drive the pressure block through the connecting block, the worker can pull out the extension rod from inside the fixing block, thereby extending the length of the connecting block. The lever principle is used to achieve the effect of saving effort, reducing the worker's workload and making it more convenient for the worker to use.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This snap-fit ​​quick-connect valve sealing joint uses an installation block, sealing ring, and pressure block / clamping block. When the installation block is inserted into the installation cavity, rotating the connecting block causes the pressure block to rotate into the installation cavity and press against the left end of the limiting groove. As the operator applies force, the pressure block is pushed through the limiting groove to compress the sealing ring, causing the sealing ring to change shape. This allows the right end of the second connecting seat to fit against the first connecting seat. At this time, the sealing ring generates a reaction force to push the right side surface of the second connecting seat to fit tightly against the clamping block, completing the installation. The operation is simple, easy to use, and improves work efficiency.

[0015] 2. This snap-fit ​​quick-connect valve sealing joint for pipelines, through the use of extension rods and fixing blocks, allows the operator to extend the length of the connecting block by pulling the extension rod out from inside the fixing block when the operator feels difficulty in driving the pressure block through the connecting block. This achieves a labor-saving effect through the lever principle, reducing the workload of the operator and making it more convenient for the operator to use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please refer to the following: Figure 1-5A snap-fit ​​quick-connect valve sealing joint for pipelines includes a connecting seat 1, with a pipeline 3 fixedly connected to the middle of the connecting seat 1. Mounting grooves 5 are formed on both sides of the connecting seat 1. Mounting seats 6 are fixedly connected to both sides of the connecting seat 1. A rotating shaft 7 is rotatably connected to the inner side of the mounting seat 6. A connecting block 8 is fixedly connected to the surface of the rotating shaft 7. A fixing block 15 is fixedly connected to the top of the connecting block 8. An extension rod 16 is slidably connected inside the fixing block 15. A pressure block 9 is fixedly connected to the bottom left end of the connecting block 8. A locking block 10 is fixedly connected to the right end of the connecting block 8. An installation cavity 2 is formed inside the connecting seat 1. A sealing ring 4 is fixedly connected to the left end of the mounting cavity 2. A mounting block 13 is slidably connected inside the mounting cavity 2. The mounting block 13 is annular in shape. The diameter of the mounting block 13 is the same as the inner wall diameter of the mounting cavity 2, and the length of the mounting block 13 is 2 mm less than the length of the mounting cavity 2. A limiting groove 14 is opened on the surface of the mounting block 13. A connecting seat 2 11 is fixedly connected to the right end of the mounting block 13. A pipe 2 12 is fixedly connected to the middle side of the connecting seat 2 11. The diameter of the pipe 1 3 is the same as the inner wall diameter of the pipe 2 12, and the right end of the pipe 1 3 extends to the inner wall of the pipe 2 12 and fits tightly against the inner wall of the pipe 2 12.

[0026] Working principle: During use, the operator aligns connector 1 with connector 2 11 and inserts mounting block 13 into the installation cavity 2. At this time, pipe 3 will also extend into the interior of pipe 2 12. By rotating connector 8, pressure block 9 will rotate into the installation cavity 2 and press against the left end of limiting groove 14. As the operator applies force, pressure block 9 will be forced through limiting groove 14 to push mounting block 13 to compress sealing ring 4, causing sealing ring 4 to deform. This will cause connector 2 11 to fit against the right end of connector 1. At this time, sealing ring 4 will generate a reaction force to push the right side surface of connector 2 11 to fit tightly against the locking block 10, completing the installation. The operation is simple, easy to use, and improves work efficiency.

[0027] Compared with related technologies, the snap-fit ​​quick-connect valve sealing joint provided by this utility model has the following advantages: By setting up an installation block 13, a sealing ring 4, etc., in conjunction with a pressure block 9 and a locking block 10, when the installation block 13 is inserted into the installation cavity 2, the pressure block 9 is rotated into the installation cavity 2 by rotating the connecting block 8 and pressing against the left end of the limiting groove 14. As the operator applies force, the pressure block 9 will be pushed by the limiting groove 14 to push the installation block 13 to squeeze the sealing ring 4, causing the sealing ring 4 to deform, thereby making the connecting seat 2 11 fit with the right end of the connecting seat 1. At this time, the sealing ring 4 generates a reaction force to push the right side surface of the connecting seat 2 11 to fit tightly with the locking block 10, completing the installation. The operation is simple, easy to use, and improves work efficiency.

[0028] Example 2:

[0029] Please refer to the following: Figure 1-6The two sides of the connecting seat 1 are fixedly connected to the mounting seats 6. The inner side of the mounting seat 6 is rotatably connected to the rotating shaft 7. The surface of the rotating shaft 7 is fixedly connected to the connecting block 8. The top of the connecting block 8 is fixedly connected to the fixing block 8. The inside of the fixing block 15 is slidably connected to the extension rod 16. The extension rod 16 is in contact with the inner wall of the fixing block 15, and the diameters at both ends of the extension rod 16 are larger than the diameter at the middle of the extension rod 16.

[0030] Working principle: When the operator feels that it is difficult to move the mounting block 13 by driving the pressure block 9 through the connecting block 8, the operator can pull out the extension rod 16 from the inside of the fixed block 15, thereby extending the length of the connecting block 8. The lever principle is used to achieve the effect of saving effort, reducing the labor burden of the operator and making it convenient for the operator to use.
