[0002] Pneumatic quick couplings are quick couplings mainly used in air piping and pneumatic tools. They are couplings that can connect or disconnect pipelines without tools. Right-angle couplings are often used as transitions when changing the direction of flow.

[0003] Existing right-angle fittings are suitable for connecting pipes of a certain size, but are not suitable for connecting different pipes at the same time or for connecting pipes of other sizes; existing right-angle fittings have a single flow regulation function and a limited adjustment range.

[0004] To address the above problems, the present invention provides a flow-adjustable pneumatic quick-release right-angle connector. Summary of the Invention

[0005] The purpose of this invention is to provide a flow-adjustable pneumatic quick-exhaust right-angle connector, including an inlet head and an outlet head. The outlet head has a second air pipe at its outlet end, and the outlet head has a first air pipe at its inlet end. The outlet end of the first air pipe and the inlet end of the second air pipe each have a first conical hole and a second conical hole, respectively.

A sealing gasket is also movably disposed on one side of the second ring body. An arc-shaped limiting plate is also disposed at the upper end of the second ring body to limit the rotation of the second ring body.

[0007] Furthermore, the first adjustment assembly also includes a second rod fixedly connected to the second sphere. The second rod is slidably connected to the inner surface of the slide groove, which is located in the middle of the second cylinder. The second cylinder is formed and machined at the end of the second air tube. A second end cap is threadedly connected to the outer side of the second cylinder. The middle part of the inner bottom surface of the second end cap is rotatably connected to the end of the second rod through a bearing.

[0008] Furthermore, the second adjustment assembly also includes a U-shaped frame fixedly connected to the first sphere, a first rod fixedly connected to one end of the U-shaped frame, the other end of the first rod being rotatably connected to the center of the inner bottom surface of the first end cover via a bearing, the first end cover being threadedly connected to the outer side of the first cylinder, the first rod being slidably connected to the inner surface of the slide groove, and a second rod passing through the inside of the U-shaped frame.

[0009] Furthermore, a sleeve is fixedly connected to the middle of the side of the first ring body, and a hole is opened in the sleeve, which extends to the middle of the other side of the first ring body. The second ring body is rotatably connected to the outer circumferential surface of the sleeve through a bearing. An arc-shaped groove is opened on the side of the second ring body, and the arc-shaped groove is evenly distributed circumferentially along the axis of the second ring body.

[0010] Furthermore, the clamping assembly also includes a connecting bent rod fixedly connected to the back of the arc-shaped pressure plate, the other end of the connecting bent rod being fixedly connected to the middle of the side of the rectangular block, the rectangular block being slidably connected to the inner surface of the T-slot, the T-slot being opened inside the first ring body, and the connecting bent rod being slidably connected to the inner surface of the arc-shaped groove.

[0011] Furthermore, the sealing gasket is attached to the middle of the side of the third ring body, the third ring body is threaded to the outer side of the sleeve, and the side of the sealing gasket is rotatably connected to the end of the pipe.

[0012] Furthermore, the outer circumferential surface of the first ring body is formed with protrusions, the end face of the protrusions is provided with a circular groove, a section of the inner surface of the circular groove is threaded, and the inner sidewall of the circular groove is provided with a rectangular groove.

[0013] Furthermore, a circular plate is slidably connected to the inner surface of the circular groove, and a connecting block is formed on the outer circumferential surface of the circular plate. The connecting block is slidably connected to the inner surface of the rectangular groove, and the end of the connecting block is fixedly connected to the middle of the side of the arc-shaped limiting plate.

[0014] Furthermore, the spring is always in a stretched state, and the arc-shaped limiting plate presses the second ring body in the initial state.

[0015] Furthermore, anti-slip strips are machined on the outer circumferential surfaces of both the second and third rings.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention provides a flow-adjustable pneumatic quick-release right-angle connector. When the pipeline needs to change flow direction, hold the device and place the pipe end on the outside of the sleeve, ensuring it fits against the sealing gasket. Then, use the handle to remove the arc-shaped limiting plate from the second ring and rotate the second ring. The rotation of the second ring causes the connecting rod to move closer to the center of the second ring. The movement of the connecting rod causes the arc-shaped pressure plate to move and clamp the outside of the pipe. Simultaneously, release the handle. Under the force of the spring, the arc-shaped limiting plate presses against the second ring. At this point, rotate the bolt, which moves towards the center of the first ring. The bolt's movement, through the circular plate, further presses the arc-shaped limiting plate against the second ring. Next, rotate the third ring. The third ring, on the sleeve, causes the sealing gasket to move, ensuring a tight fit between the sealing gasket and the pipe end. Repeat the above operations to... The pipes connected to the gas inlet and outlet are securely fastened and sealed. Next, the flow rate of the pipeline is regulated by rotating the second end cap. The second end cap moves, causing the second ball to move within the first conical hole via the second rod, thus changing the flow rate within the first conical hole. If further flow rate adjustment is needed, rotating the first end cap moves, causing the first ball to move within the second conical hole via the first rod, further regulating the input gas flow rate. This design aims to clamp pipes of different specifications using an adjustable arc-shaped pressure plate to accommodate changes in flow direction for different pipe sizes. The movement of the third ring further seals the pipe, ensuring a tight seal. Pre-clamping with an arc-shaped limiting plate and secondary clamping ensure the pipe does not loosen after clamping. This allows for multi-stage adjustment of the gas flow rate within the pipeline, facilitating precise control. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-6 An adjustable pneumatic quick-exhaust right-angle connector includes an inlet head 1 and an outlet head 2. The outlet end of the inlet head 1 is provided with a second air pipe 4, and the inlet end of the outlet head 2 is provided with a first air pipe 3. A first conical hole 5 and a second conical hole 36 are respectively provided inside the outlet end of the first air pipe 3 and the inlet end of the second air pipe 4. The first air pipe 3 and the second air pipe 4 intersect perpendicularly and are interconnected. A first adjustment component is provided at the end of the second air pipe 4 away from the inlet end. The first adjustment component includes a second ball 15 disposed inside the first conical hole 5. The second ball 15 reciprocates linearly along the axis of the inlet head 1 to adjust the gas flow rate within the first conical hole 5. A second adjustment component is provided at the end of the first air pipe 3 away from the outlet end. The second adjustment component includes a second conical hole 5 disposed inside the first conical hole 5. The first sphere 13 inside the hole 36 reciprocates linearly along the axis of the outlet head 2 to adjust the gas flow rate in the second conical hole 36. The inlet end of the inlet head 1 and the outlet end of the outlet head 2 are both provided with a first ring body 16. A second ring body 18 is provided in the middle of the side of the first ring body 16. A clamping assembly is provided on the first ring body 16. The clamping assembly includes an arc-shaped pressure plate 24 provided on one side of the second ring body 18. The arc-shaped pressure plate 24 is evenly distributed circumferentially along the axis of the second ring body 18. The rotation of the second ring body 18 is used to drive the arc-shaped pressure plate 24 to move radially away from or towards the first ring body 16. A sealing gasket 26 is also movably provided on one side of the second ring body 18. An arc-shaped limiting plate 32 is also provided at the upper end of the second ring body 18 to limit the rotation of the second ring body 18.

[0027] Specifically, when the pipeline needs to change its flow direction, hold the device and place the pipe end on the outside of the sleeve 17, ensuring it fits against the sealing gasket 26. Then, use the handle 33 to remove the arc-shaped limiting plate 32 from the second ring 18 and rotate the second ring 18. The rotation of the second ring 18 causes the connecting bent rod 23 to move closer to the center of the second ring 18. The movement of the connecting bent rod 23 causes the arc-shaped pressure plate 24 to move and clamp the outside of the pipe. While clamping, release the handle 33. Under the force of the spring 29, the arc-shaped limiting plate 32 presses against the second ring 18. At this time, rotate the bolt 34. The bolt 34 moves towards the center of the first ring 16. The movement of the bolt 34, through the circular plate 30, causes the arc-shaped limiting plate 32 to further press against the second ring 18. Immediately afterwards, rotate the third ring 25. The third ring 25 moves the sealing gasket 26 on the sleeve 17, making the sealing gasket 26 fit tightly against the pipe end. Repeat this process. The above operations secure and seal the pipes connected to the inlet head 1 and outlet head 2. Next, the flow rate of the pipeline is adjusted by rotating the second end cap 9. The second end cap 9 moves, and the second rod 14 drives the second ball 15 to move within the first conical hole 5, changing the flow rate within the first conical hole 5. If further flow rate adjustment is needed, rotate the first end cap 8. The first end cap 8 moves, and the first rod 10 drives the first ball 13 to move within the second conical hole 36, further adjusting the flow rate of the input gas. The purpose of this design is to clamp pipes of different specifications by adjusting the arc-shaped pressure plate 24 to accommodate changes in the flow direction of pipes of different specifications; to further seal the pipe by moving the third ring 25 to ensure airtightness; to ensure that the pipe does not loosen after clamping by the pre-compression of the arc-shaped limiting plate 32 and the secondary compression; and to ensure that the gas flow rate in the pipeline can be adjusted in multiple stages for precise control.

[0028] The first adjustment assembly also includes a second rod 14 fixedly connected to the second ball 15. The second rod 14 is slidably connected to the inner surface of the slide groove 11, which is located in the middle of the second cylinder 7. The second cylinder 7 is formed at the end of the second air pipe 4. A second end cap 9 is threadedly connected to the outer side of the second cylinder 7. The middle of the inner bottom surface of the second end cap 9 is rotatably connected to the end of the second rod 14 through a bearing. The purpose of this design is that the second end cap 9 rotates and drives the second ball 15 to move within the first conical hole 5 through the second rod 14, thereby changing the gas flow rate within the first conical hole 5.

[0029] The second adjustment assembly also includes a U-shaped frame 12 fixedly connected to the first ball 13. A first rod 10 is fixedly connected to one end of the U-shaped frame 12. The other end of the first rod 10 is rotatably connected to the middle of the inner bottom surface of the first end cover 8 through a bearing. The first end cover 8 is threadedly connected to the outer side of the first cylinder 6. The first rod 10 is slidably connected to the inner surface of the slide groove 11. A second rod 14 is inserted inside the U-shaped frame 12. The purpose of this design is that the first end cover 8 rotates and drives the first ball 13 to move in the second conical hole 36 through the U-shaped frame 12, thereby changing the gas flow rate in the second conical hole 36.

[0030] A sleeve 17 is fixedly connected to the middle of the side of the first ring body 16. A hole is opened in the sleeve 17, which extends to the middle of the other side of the first ring body 16. The second ring body 18 is rotatably connected to the outer circumferential surface of the sleeve 17 through a bearing. An arc-shaped groove 20 is opened on the side of the second ring body 18. The arc-shaped groove 20 is evenly distributed circumferentially along the axis of the second ring body 18. The purpose of this design is to ensure that the second ring body 18 can rotate.

[0031] The clamping assembly also includes a connecting rod 23 fixedly connected to the back of the arc-shaped pressure plate 24. The other end of the connecting rod 23 is fixedly connected to the middle of the side of the rectangular block 22. The rectangular block 22 is slidably connected to the inner surface of the T-slot 21. The T-slot 21 is opened inside the first ring body 16. The connecting rod 23 is slidably connected to the inner surface of the arc-shaped groove 20. The purpose of this design is that the second ring body 18 rotates and drives the arc-shaped pressure plate 24 to move towards or away from each other through the connecting rod 23, thereby clamping the pipe.

[0032] The sealing gasket 26 is attached to the middle of the side of the third ring body 25. The third ring body 25 is threaded to the outer side of the sleeve 17. The side of the sealing gasket 26 is rotatably connected to the end of the pipe. The purpose of this design is to ensure a tight seal by rotating the third ring body 25 so that the side of the sealing gasket 26 fits tightly to the end of the pipe.

[0033] The outer circumferential surface of the first ring body 16 is formed with a protrusion 27, the end face of the protrusion 27 is provided with a circular groove 28, a section of the inner surface of the circular groove 28 is provided with a thread, and the inner sidewall of the circular groove 28 is provided with a rectangular groove 35.

[0034] A circular plate 30 is slidably connected to the inner surface of the circular groove 28. A connecting block 31 is formed on the outer circumferential surface of the circular plate 30. The connecting block 31 is slidably connected to the inner surface of the rectangular groove 35. The end of the connecting block 31 is fixedly connected to the middle of the side of the arc-shaped limiting plate 32. A handle 33 is fixedly connected to the middle of the arc-shaped limiting plate 32. The end face of the circular plate 30 and the inner bottom surface of the circular groove 28 are respectively fixedly connected to the end of the spring 29. The circular groove 28 is threadedly connected to the bolt 34. The bolt 34 is rotatably connected to the end face of the circular plate 30. The purpose of this design is that under the action of the spring 29, the arc-shaped limiting plate 32 initially presses the second ring 18, and at the same time, the bolt 34 rotates to further press the second ring 18.

[0035] The spring 29 is always in a stretched state, and the arc-shaped limiting plate 32 presses the second ring 18 in the initial state. The purpose of this design is to ensure the rationality of the structure.

[0036] The outer circumference of both the second ring body 18 and the third ring body 25 is machined with anti-slip strips 19, which is designed to facilitate rotation.

[0037] In summary: When the pipeline needs to change direction, hold this device and place the pipe end on the outside of the sleeve 17, ensuring it fits against the sealing gasket 26. Then, use the handle 33 to remove the arc-shaped limiting plate 32 from the second ring 18 and rotate the second ring 18. The rotation of the second ring 18 causes the connecting rod 23 to move closer to the center of the second ring 18. The movement of the connecting rod 23 causes the arc-shaped pressure plate 24 to move and clamp the outside of the pipe. Simultaneously, release the handle 33. Under the force of the spring 29, the arc-shaped limiting plate 32 presses against the second ring 18. At this time, rotate the bolt 34. The bolt 34 moves towards the center of the first ring 16. The movement of the bolt 34, through the circular plate 30, causes the arc-shaped limiting plate 32 to further press against the second ring 18. Then, rotate the third ring 25. The third ring 25 moves the sealing gasket 26 on the sleeve 17, ensuring the sealing gasket 26 fits tightly against the pipe end. Repeat this process. The above operations secure and seal the pipes connected to the inlet head 1 and outlet head 2. Next, the flow rate of the pipeline is adjusted by rotating the second end cap 9. The second end cap 9 moves, and the second rod 14 drives the second ball 15 to move within the first conical hole 5, changing the flow rate within the first conical hole 5. If further flow rate adjustment is needed, rotate the first end cap 8. The first end cap 8 moves, and the first rod 10 drives the first ball 13 to move within the second conical hole 36, further adjusting the flow rate of the input gas. The purpose of this design is to clamp pipes of different specifications by adjusting the arc-shaped pressure plate 24 to accommodate changes in the flow direction of pipes of different specifications; to further seal the pipe by moving the third ring 25 to ensure airtightness; to ensure that the pipe does not loosen after clamping by the pre-compression of the arc-shaped limiting plate 32 and the secondary compression; and to ensure that the gas flow rate in the pipeline can be adjusted in multiple stages for precise control.
