Description

Technical Field

[0001] This utility model relates to the field of pipe fitting technology, specifically to a flared adjustable pipe fitting. Background Technology

[0002] Pipe fittings are connecting tools between pipes, serving as detachable connection points between components and pipes. They play an indispensable and crucial role in pipe fittings.

[0003] Flared pipe fittings are widely used in high-pressure pipeline applications in industrial fields, such as shipbuilding, offshore oil, metal processing, and mining. Flared pipe fittings are suitable for hydraulic, lubrication, high-pressure water flushing, and high-pressure air pipelines. Flared pipe fittings are highly reliable, inherently clean, and flexible. Their pre-processing, assembly, and installation are quicker and easier. Flared connections eliminate the need for welding, saving subsequent pickling and flaw detection processes.

[0004] Existing pipe bends are typically used for pipe connections. Most existing pipe bends are fixed angles. After installation, if the connection angle of the pipe bend needs to be adjusted, the pipe bend needs to be disassembled and reinstalled, which is very inconvenient and lacks flexibility.

[0005] Therefore, we propose a flared adjustable pipe fitting. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a flared adjustable pipe fitting, which solves the problem that most existing bend fittings have a fixed angle, making it cumbersome to adjust the connection angle and inconvenient to use.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a flared adjustable pipe fitting, comprising a connecting pipe and a flared bend, wherein a connecting plate is provided at one end of the connecting pipe, and an annular connecting groove is formed on the surface of the connecting plate; a connecting protrusion adapted to the annular connecting groove is provided at one end of the flared bend; a limiting plate is sleeved on the surface of the flared bend; multiple bolts are inserted into the limiting plate; and the limiting plate is fixedly mounted on the connecting plate by bolts.

[0010] The outer circumference of the connecting convex ring is provided with several annularly distributed positioning grooves, and the connecting disc is provided with a positioning element on one side of the annular connecting groove.

[0011] By adopting the above technical solution, the connecting pipe and the flared bend can be connected and assembled before use. During assembly, the connecting protrusion of the flared bend is inserted into the annular connecting groove of the connecting plate to make the connecting pipe and the flared bend align. Then, the limiting plate is pressed against the connecting plate, and the limiting plate is fixed to the connecting plate with bolts. The limiting plate and the connecting protrusion are used to limit the connection, thus restricting the connecting protrusion within the annular connecting groove.

[0012] Preferably, a first sealing ring abuts between the connecting protrusion and the annular connecting groove.

[0013] By adopting the above technical solution, the sealing performance of the connection between the connecting pipe and the flared bend can be improved.

[0014] Preferably, a second sealing ring abuts between the limiting disc and the connecting protrusion.

[0021] By adopting the above technical solution, when it is necessary to adjust the angle of the flared bend, simply press the movable block and slide it into the groove. Utilizing the cooperation between the guide rod and the guide hole, the movable block drives the positioning rod to slide into the groove, allowing the positioning rod to move out of the positioning slot. After releasing the angle positioning of the connecting convex ring, the flared bend can be rotated and adjusted. After adjustment, the positioning rod can be inserted into the corresponding positioning slot to orient the flared bend. There is no need to reinstall the flared bend, making it convenient to use and enhancing flexibility.

[0022] Preferably, a limiting block is provided on the inner wall of the groove.

[0023] By adopting the above technical solution, the movable block can be limited, preventing it from detaching from the groove.

[0036] This utility model provides a technical solution:

[0037] Please see Figures 1-4 A flared adjustable pipe fitting includes a connecting pipe 1 and a flared bend 2. One end of the connecting pipe 1 is provided with a connecting plate 11, and the surface of the connecting plate 11 has an annular connecting groove 12. One end of the flared bend 2 is provided with a connecting protrusion 21 that matches the annular connecting groove 12. A limiting plate 22 is fitted onto the surface of the flared bend 2, and multiple bolts 23 are inserted into the limiting plate 22. The limiting plate 22 is fixedly mounted on the connecting plate 11 by the bolts 23. The fitting is designed with a connecting pipe 1 and a flared bend 2. Before use, the connecting pipe 1 and the flared bend pipe 2 can be connected and assembled. During assembly, the connecting protrusion 21 of the flared bend pipe 2 is inserted into the annular connecting groove 12 of the connecting plate 11 so that the connecting pipe 1 and the flared bend pipe 2 are connected. Then, the limiting plate 22 is pressed against the connecting plate 11, and the limiting plate 22 is fixed to the connecting plate 11 with the bolts 23. The limiting plate 22 and the connecting protrusion 21 are limited by the limiting plate 22, and the connecting protrusion 21 is restricted in the annular connecting groove 12.

[0038] Furthermore, a first sealing ring 25 abuts between the connecting convex ring 21 and the annular connecting groove 12, and a second sealing ring 26 abuts between the limiting disc 22 and the connecting convex ring 21. By setting the first sealing ring 25 and the second sealing ring 26, the sealing performance at the connection between the connecting pipe 1 and the flared bend 2 can be improved.

[0039] Reference Figure 2 and Figure 4The outer circumference of the connecting ring 21 is provided with a plurality of annularly distributed positioning grooves 24, the number of positioning grooves 24 being at least four. A positioning element 13 is provided on one side of the connecting plate 11 located in the annular connecting groove 12. A groove 14 is provided on the side of the connecting plate 11 near the connecting pipe 1. The positioning element 13 includes a positioning rod 131 slidably installed between the groove 14 and the annular connecting groove 12 and a spring 132 sleeved on the positioning rod 131. One end of the spring 132 abuts against a limit ring 133, which is integrally provided on the surface of the positioning rod 131. The positioning rod 131 faces the annular connecting groove 12. The opening of the groove 12 is angled. By setting the positioning groove 24 and the positioning element 13, when the connecting convex ring 21 is inserted into the annular connecting groove 12, the connecting convex ring 21 will squeeze the angle of the positioning rod 131, causing the positioning rod 131 to retract into the groove 14. After the connecting convex ring 21 is fully inserted into the annular connecting groove 12, the flared bend 2 is rotated to a suitable angle so that the positioning rod 131 is aligned with a certain positioning groove 24. The spring 132 extends and pushes the positioning rod 131 into the positioning groove 24, which can fix the angle of the flared bend 2 and ensure the stability of the angle of the flared bend 2.

[0040] Furthermore, a movable block 134 is slidably installed inside the groove 14, and a guide rod 135 is fixedly connected inside the movable block 134. A guide hole 136 is opened at one end of the positioning rod 131 located inside the groove 14, and the guide rod 135 slides in the guide hole 136. By setting the movable block 134, when it is necessary to adjust the angle of the flared bend 2, it is only necessary to press the movable block 134 to make the movable block 134 slide into the groove 14. With the cooperation of the guide rod 135 and the guide hole 136, the movable block 134 drives the positioning rod 131 to slide into the groove 14, so that the positioning rod 131 moves out of the positioning groove 24. After releasing the angle positioning of the connecting convex ring 21, the flared bend 2 can be rotated and adjusted. After the adjustment is completed, the positioning rod 131 is inserted into the corresponding positioning groove 24 to orient the flared bend 2. There is no need to reinstall the flared bend 2, which is convenient to use and enhances flexibility.

[0041] Furthermore, a limiting block 15 is provided on the inner wall of the groove 14. By providing the limiting block 15, the movable block 134 can be limited, preventing the movable block 134 from detaching from the groove 14.

[0042] In practical use, the working principle of this utility model is as follows:

[0043] First, before use, the connecting pipe 1 and the flared elbow 2 can be connected and assembled. During assembly, the connecting protrusion 21 of the flared elbow 2 is inserted into the annular connecting groove 12 of the connecting plate 11 so that the connecting pipe 1 and the flared elbow 2 are connected. Then, the limiting plate 22 is pressed against the connecting plate 11, and the limiting plate 22 is fixed to the connecting plate 11 with the bolts 23. The limiting plate 22 and the connecting protrusion 21 are limited by the limiting plate 22, and the connecting protrusion 21 is restricted in the annular connecting groove 12.

[0044] When the connecting protrusion 21 is inserted into the annular connecting groove 12, the connecting protrusion 21 will squeeze the angle of the positioning rod 131, causing the positioning rod 131 to retract into the groove 14. After the connecting protrusion 21 is fully inserted into the annular connecting groove 12, rotate the flared bend 2 to a suitable angle so that the positioning rod 131 is aligned with a certain positioning groove 24. The spring 132 extends and pushes the positioning rod 131 into the positioning groove 24, which can fix the angle of the flared bend 2 and ensure the stability of the angle of the flared bend 2.

[0045] When it is necessary to adjust the angle of the flared bend 2, simply press the movable block 134 to slide it into the groove 14. With the cooperation of the guide rod 135 and the guide hole 136, the movable block 134 drives the positioning rod 131 to slide into the groove 14, so that the positioning rod 131 moves out of the positioning groove 24. After releasing the angle positioning of the connecting convex ring 21, the flared bend 2 can be rotated and adjusted. After the adjustment is completed, the positioning rod 131 is inserted into the corresponding positioning groove 24 to orient the flared bend 2.

[0046] In summary, this flared adjustable pipe fitting, by setting the positioning groove 24 and the positioning element 13, allows the flared bend 2 to be rotated and adjusted simply by pressing the movable block 134 when the angle needs to be adjusted, without the need to reinstall the flared bend 2, making it convenient to use and enhancing its flexibility.

[0047] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
