Description

Technical Field

[0001] This utility model relates to the field of conversion port technology, specifically a conversion port that facilitates the connection of multiple pipe diameters. Background Technology

[0002] Pipeline connections are a common and important task in many scenarios, including industrial production and daily life. Different equipment and systems often need to transport fluids (such as liquids and gases) through pipelines. However, due to various reasons, different pipelines may have different diameters, requiring adapters to connect pipelines of different diameters.

[0003] Existing pipe adapters typically use simple plug-in, socket-in, or interchangeable adapters of different sizes to achieve multi-diameter pipe connections. Traditional adapters are difficult to quickly and accurately achieve stable connections between pipes of different diameters, and cannot meet the needs of actual production and daily life for efficient and reliable pipe connections. Therefore, an adapter that facilitates multi-diameter pipe connections is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a conversion port that facilitates the connection of multiple pipe diameters, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a conversion port for easy connection of multiple pipe diameters, comprising a connecting frame, wherein a first connecting pipe is provided on one side of the connecting frame, and a plurality of second connecting pipes are provided on the other side of the connecting frame;

[0006] One side of the connecting frame is provided with a pushing component for limiting the position of the first connecting tube;

[0007] The pushing component is provided with a limiting component on one side for limiting the rotation of the second connecting pipe;

[0008] The pushing assembly includes a support frame, an annular frame fixed to one side of the support frame, a sealing ring adhered to one side of the annular frame, two connecting plates fixed to the outer side of the annular frame, a sliding rod movably passing through one side of the connecting plate, and a first spring sleeved on the outer side of the sliding rod;

[0009] The limiting component includes a turntable, and a plurality of limiting grooves located on one side of the turntable are provided on one side of the second connecting pipe.

[0010] Preferably, the first spring is connected at both ends to the inner wall of the connecting frame and one side of the connecting plate, respectively, and one end of the support frame is fixedly connected to the first connecting pipe.

[0011] Preferably, the connecting frame is threaded with a first bolt on one side. When the first bolt is tightened, one end abuts against the outer side of the ring frame, and the outer side of the support frame is inserted into one side of the connecting frame.

[0012] Preferably, the connecting frame is fixed to the outside of the connecting frame, the fixed frame has a sliding groove inside, and a second spring is provided inside the sliding groove.

[0013] Preferably, the above-mentioned slidably connects a ball to the inner side of the groove, and the two ends of the second spring are respectively connected to the ball and one side of the groove.

[0014] Preferably, the turntable is rotatably connected to the inner side of the connecting frame. When the ball is located inside the limiting groove, the turntable rotates to a predetermined angle to connect the corresponding second connecting pipe with the first connecting pipe.

[0015] Preferably, the connecting frame is threaded with a second bolt on its outer side. When the second bolt is tightened, one end of the second bolt abuts against the outer side of the turntable, and one side of the second connecting pipe is fixed to one side of the turntable.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0017] 1. When the position of the first connecting pipe does not need to be adjusted, the first bolt connected by the thread on one side of the connecting frame can be tightened so that one end of the first bolt abuts against the outside of the ring frame, thereby fixing the position of the pushing component. The operator can fix the pushing component at any time according to actual needs, ensuring that the first connecting pipe will not be displaced due to unexpected factors when the first connecting pipe does not need to be adjusted, thus ensuring the stability of the device operation.

[0018] 2. When the turntable is rotated, the ball slides along the surface of the turntable under the elastic force of the second spring. When the turntable rotates to a predetermined angle, connecting the corresponding second connecting pipe with the first connecting pipe, the ball is located inside the limiting groove. At this time, the ball is blocked by the limiting groove, and the turntable cannot rotate freely, ensuring that the selected second connecting pipe can stably connect with the first connecting pipe. After the second connecting pipe is connected with the first connecting pipe and the position of the turntable is determined, the second bolt is tightened so that one end of the second bolt abuts against the outside of the turntable, thereby fixing the position of the turntable and preventing the turntable from rotating due to vibration or other reasons during operation. This ensures the reliability of the pipe connection and reduces the failures and safety hazards caused by unstable pipe connections. Attached Figure Description

[0030] Example

[0031] Please see Figure 1-7 This utility model provides a technical solution: a conversion port for easy connection of multiple pipe diameters, including a connecting frame 1, a first connecting pipe 2 on one side of the connecting frame 1, and a plurality of second connecting pipes 4 on the other side of the connecting frame 1; the diameter of the second connecting pipes 4 is smaller than the diameter of the first connecting pipe 2, and one end of the first connecting pipe 2 and the second connecting pipe 4 can be connected to a flexible hose respectively; a pushing component 3 for limiting the position of the first connecting pipe 2 is provided on one side of the connecting frame 1; a limiting component 6 for limiting the rotation of the second connecting pipes 4 is provided on one side of the pushing component 3;

[0032] The pushing component 3 includes a support frame 35, with an annular frame 36 fixed to one side of the support frame 35. A sealing ring 34 is adhered to one side of the annular frame 36. When the sealing ring 34 adhered to one side of the annular frame 36 is in contact with the turntable 62, it provides a seal and prevents leakage at the connection. In scenarios requiring sealing, it ensures that the medium inside the device does not leak out, avoiding resource waste, environmental pollution, and potential safety hazards caused by leakage. The two ends of the first spring 32 are respectively connected to the inner wall of the connecting frame 1 and one side of the connecting plate 33. One end of the support frame 35 is fixedly connected to the first connecting pipe 2. A first bolt 5 is threadedly connected to one side of the connecting frame 1. When the first bolt 5 is tightened, one end abuts against the outer side of the annular frame 36, and the outer side of the support frame 35 is inserted into one side of the connecting frame 1.

[0033] In the initial state, the preload of the first spring 32 keeps the sealing ring 34 sealed. Two connecting plates 33 are fixed to the outside of the annular frame 36. A sliding rod 31 that moves through one side of the connecting frame 1 is fixed to one side of the connecting plate 33. The first spring 32 is sleeved on the outside of the sliding rod 31. In the initial state, the pushing assembly 3 is in a relatively stable position. The support frame 35 is fixedly connected to the first connecting pipe 2 and connected to the connecting frame 1 through the sliding rod 31 and the connecting plate 33. At the same time, the first spring 32 is sleeved on the outside of the sliding rod 31. The two ends of the first spring 32 are respectively connected to the inner wall of the connecting frame 1 and one side of the connecting plate 33. The elastic force of the first spring 32 enables the pushing assembly 3 to maintain a stable position when it is not disturbed by external forces, which is conducive to the normal operation of the entire device.

[0034] The limiting component 6 includes a turntable 62, with several limiting grooves 63 on one side of the turntable 62 located on the side of the second connecting pipe 4. A fixing frame 61 is fixed to the outside of the connecting frame 1, and a sliding groove 66 is formed inside the fixing frame 61. A second spring 65 is provided inside the sliding groove 66, and a ball 64 is slidably connected inside the sliding groove 66. The two ends of the second spring 65 are respectively connected to one side of the ball 64 and the sliding groove 66, connecting the first connecting pipe 2 with second connecting pipes 4 of different diameters, greatly improving the versatility and adaptability of the device. In practical applications, different scenarios may require connecting pipes of different diameters. This technical solution does not require replacing a large number of parts; it can achieve the connection of pipes of different sizes through simple operation, reducing the cost of use and the difficulty of operation.

[0035] When the first connecting pipe 2 is pulled, the slide rod 31 slides along the connecting frame 1 and compresses the first spring 32. After the turntable 62 rotates to the position, it is released, and the spring pushes the sealing ring 34 to reset and fit.

[0036] The ball 64, pushed by the second spring 65, is inserted into the limiting groove 63, achieving initial positioning. The turntable 62 is rotatably connected to the inner side of the connecting frame 1. When the ball 64 is inside the limiting groove 63, the turntable 62 rotates to a predetermined angle, connecting the corresponding second connecting pipe 4 with the first connecting pipe 2. The outer side of the connecting frame 1 is threaded with a second bolt 7. When the second bolt 7 is tightened, one end of the second bolt 7 abuts against the outer side of the turntable 62. One side of the second connecting pipe 4 is fixed to one side of the turntable 62. Loosening the first bolt 5 and pulling the first connecting pipe 2 to one side causes the sealing ring 34 to leave one side of the turntable 62, allowing subsequent rotation of the turntable 62 to select the appropriate second connecting pipe 4 for connection. The entire operation is simple and direct, requiring no complex tools or professional skills, greatly shortening the pipe connection time and improving work efficiency.

[0037] Working principle: In the initial state, the support frame 35 in the push assembly 3 is fixedly connected to the first connecting pipe 2. The annular frame 36 on one side of the support frame 35 is connected to the connecting frame 1 through two connecting plates 33 and a sliding rod 31 that moves through the connecting frame 1. A first spring 32 is sleeved on the outside of the sliding rod 31, and the two ends of the first spring 32 are respectively connected to the inner wall of the connecting frame 1 and one side of the connecting plate 33. At this time, under the elastic force of the first spring 32, the push assembly 3 is in a relatively stable position. At the same time, the sealing ring 34 bonded to one side of the annular frame 36 acts as a seal when it is in contact with the turntable 62, preventing leakage at the connection.

[0038] When there is no need to adjust the position of the first connecting pipe 2, the first bolt 5 connected by the thread on one side of the connecting frame 1 can be tightened so that one end of the first bolt 5 abuts against the outside of the ring frame 36. The first bolt 5 serves to fix the position of the pushing component 3.

[0039] When it is necessary to connect the first connecting pipe 2 with the second connecting pipe 4 of different diameters, loosen the first bolt 5 and pull the first connecting pipe 2 to one side, so that the first spring 32 is compressed and the sealing ring 34 is controlled to move away from one side of the turntable 62. When the turntable 62 is rotated, the ball 64 will slide along the surface of the turntable 62 under the elastic force of the second spring 65. When the turntable 62 rotates to a predetermined angle, so that the corresponding second connecting pipe 4 is connected with the first connecting pipe 2, the ball 64 is exactly inside the limiting groove 63. At this time, the ball 64 is blocked by the limiting groove 63, and the turntable 62 cannot rotate at will, thus realizing the limiting of the rotation angle of the turntable 62, ensuring that the selected second connecting pipe 4 can be stably connected with the first connecting pipe 2. After the second connecting pipe 4 is connected with the first connecting pipe 2 and the position of the turntable 62 is determined, tighten the second bolt 7 so that one end of the second bolt 7 abuts against the outside of the turntable 62, thereby fixing the position of the turntable 62 and preventing the turntable 62 from rotating due to vibration or other reasons during operation, which would affect the reliability of the pipe connection.

[0040] In summary, when there is no need to adjust the position of the first connecting pipe 2, the first bolt 5 connected by the thread on one side of the connecting frame 1 can be tightened so that one end of the first bolt 5 abuts against the outside of the ring frame 36, thereby fixing the position of the pushing component 3. The operator can fix the pushing component 3 at any time according to actual needs, ensuring that the first connecting pipe 2 will not be displaced due to unexpected factors when there is no need to adjust it, thus ensuring the stability of the device operation.

[0041] When the turntable 62 is rotated, the ball 64 slides along the surface of the turntable 62 under the elastic force of the second spring 65. When the turntable 62 rotates to a predetermined angle, so that the corresponding second connecting pipe 4 is connected to the first connecting pipe 2, the ball 64 is exactly inside the limiting groove 63. At this time, the ball 64 is blocked by the limiting groove 63, and the turntable 62 cannot rotate at will, ensuring that the selected second connecting pipe 4 can be stably connected to the first connecting pipe 2. After the second connecting pipe 4 is connected to the first connecting pipe 2 and the position of the turntable 62 is determined, the second bolt 7 is tightened so that one end of the second bolt 7 abuts against the outside of the turntable 62, thereby fixing the position of the turntable 62 and preventing the turntable 62 from rotating due to vibration or other reasons during operation. This ensures the reliability of the pipe connection and reduces the failures and safety hazards caused by unstable pipe connections.
