Description

Technical Field

[0001] This utility model relates to the field of pneumatic connection device technology, and in particular to a pneumatic connector with adjustable flow rate. Background Technology

[0002] Adjustable flow pneumatic fittings are connectors used in pneumatic systems. They not only connect pipes but also regulate gas flow. They typically have standard pneumatic interfaces, such as quick-connect or threaded interfaces. Quick-connect interfaces facilitate rapid installation and disassembly in pneumatic systems and have an internal sealing structure, usually using rubber sealing rings, to ensure no gas leakage. Threaded interfaces provide a more secure connection and are suitable for applications requiring resistance to pressure and vibration. Adjustable flow pneumatic fittings are widely used in automated production lines, laboratory equipment, and medical devices.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: during transportation, the pneumatic connector may be squeezed and collided with each other. If the button is squeezed for a long time, the button's rebound force may decrease, causing the button to fail to rebound normally during use. Therefore, an adjustable flow pneumatic connector is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing pneumatic connectors where buttons are subjected to prolonged compression during transportation, leading to a decrease in button rebound force and preventing the buttons from rebounding properly. This invention proposes an adjustable flow pneumatic connector.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable flow pneumatic connector, comprising a button and a valve body. A fixing buckle is slidably connected to the arc surface of the button. A locking buckle is slidably connected to the inner wall of the fixing buckle. A pressure ring is slidably connected to the arc surface of the locking buckle. A shaped sealing ring is slidably connected to one side of the pressure ring. A plastic part is mounted on the arc surface of the locking buckle. An upper O-ring is mounted on the inner wall of the valve body. A middle sealing plate is mounted on the inner wall of the valve body. A lower O-ring is mounted on the inner wall of the valve body. The inner wall of the valve body rotates... A valve stem body is connected to the valve stem body. A fixed locking wheel is installed on the arc surface of the valve stem body. An adjusting wheel is fixedly connected to the surface of the valve stem body. A fixed valve stem wheel is installed on the arc surface of the valve stem body. A valve stem O-ring is installed on the arc surface of the valve stem body. A fixed ring is fixedly connected to the arc surface of the plastic part body. Four connecting rods are fixedly connected to the surface of the fixed ring. A protective ring is fixedly connected to the end of the four connecting rods away from the fixed ring. A U-shaped plate is fixedly connected to the arc surface of the protective ring. A rotating rod is rotatably connected to the inner surface of the U-shaped plate. A protective plate is fixedly connected to the arc surface of the rotating rod.

[0006] The effect achieved by the above components is to protect the button, preventing the button from being squeezed for a long time during transportation, which would reduce the button's rebound force and cause the button to fail to rebound normally.

[0007] Preferably, a fixing rod is fixedly connected to the arc surface of the protective ring, an operating plate is slidably connected to the arc surface of the fixing rod, an insert rod is fixedly connected to the side of the operating plate near the protective ring, and a slot is provided on the arc surface of the protective plate.

[0008] The aforementioned components achieve the following effect: they can fix the protective plate in place, preventing the protective plate from being passively opened due to bumpy roads during transportation, thus reducing the protective effect of the plate.

[0009] Preferably, the end of the fixing rod away from the protective ring has a groove, and a blocking block is fixedly connected to the surface of the groove of the fixing rod.

[0010] The effect achieved by the above-mentioned components is that the blocking block can block the control panel, preventing the control panel from slipping off the arc surface of the fixing rod when the operator pulls it with excessive force.

[0011] Preferably, a spring is fitted onto the arc surface of the fixing rod, and the two ends of the spring are fixedly connected to the operating plate and the protective ring, respectively.

[0012] The effect achieved by the above components is that the spring's rebound force automatically inserts the plug rod, while preventing the plug rod from detaching from the surface of the protective plate slot, thus improving the stability of the plug rod when fixing the protective plate.

[0013] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the U-shaped plate and the protective plate, respectively.

[0014] The effect achieved by the above components is that the torsion spring's torque enables the protective plate to open automatically, while keeping the protective plate open, thus facilitating the use of the buttons by the staff.

[0015] Preferably, an anti-slip pad is fixedly connected to the surface of the button, and a plurality of anti-slip protrusions are fixedly connected to the surface of the anti-slip pad.

[0016] The effect achieved by the above components is that the anti-slip pads achieve an anti-slip effect, increase the friction of the button surface, and prevent the operator from slipping when pressing the button.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] 1. In this utility model, the button can be protected, avoiding the situation where the button is squeezed for a long time during the transportation of the pneumatic connector, which would reduce the button's rebound force and cause the button to fail to rebound normally.

[0028] Reference Figures 1-8As shown, this utility model provides a technical solution: an adjustable flow pneumatic connector, including a button 1 and a valve body 15. A fixing buckle 2 is slidably connected to the arc surface of the button 1. A locking buckle 3 is slidably connected to the inner wall of the fixing buckle 2. A pressure ring 4 is slidably connected to the arc surface of the locking buckle 3. A special-shaped sealing ring 5 is slidably connected to one side of the pressure ring 4. A plastic body 6 is installed on the arc surface of the locking buckle 3. An upper O-ring 12 is installed on the inner wall of the valve body 15. A middle sealing plate 13 is installed on the inner wall of the valve body 15. A lower O-ring 14 is installed on the inner wall of the valve body 15. A valve stem body 10 is rotatably connected to the inner wall of the valve body 15. A fixing locking wheel 7 is installed on the arc surface of the valve stem body 10. An adjusting wheel is fixedly connected to the surface of the valve stem body 10. 8. A fixed valve stem wheel 9 is installed on the arc surface of the valve stem body 10, and a valve stem O-ring 11 is installed on the arc surface of the valve stem body 10. A fixed ring 16 is fixedly connected to the arc surface of the plastic part body 6. Four connecting rods 17 are fixedly connected to the surface of the fixed ring 16. A protective ring 18 is fixedly connected to the end of the four connecting rods 17 away from the fixed ring 16. A U-shaped plate 19 is fixedly connected to the arc surface of the protective ring 18. A rotating rod 20 is rotatably connected to the inner surface of the U-shaped plate 19. A protective plate 21 is fixedly connected to the arc surface of the rotating rod 20. This achieves the effect of protecting the button 1, avoiding the situation where the button 1 is squeezed for a long time during the transportation of the pneumatic connector, which would cause the button 1 to lose its rebound force and fail to rebound normally. The protective ring 18 A fixed rod 22 is fixedly connected to the arc surface of the protective plate 21. An operating plate 23 is slidably connected to the arc surface of the fixed rod 22. A plug rod 24 is fixedly connected to the side of the operating plate 23 near the protective ring 18. A slot is provided on the arc surface of the protective plate 21. When the operator needs to use the protective plate 21 to protect the button 1, rotating the protective plate 21 causes the rotating rod 20 to rotate. When the surface of the protective plate 21 contacts the protective ring 18, the protective plate 21 completely covers the surface of the button 1. Pushing the operating plate 23 causes the plug rod 24 to move. When the plug rod 24 is inserted into the surface of the slot in the protective plate 21, it fixes the protective plate 21, achieving the effect of fixing the protective plate 21 and preventing damage from bumpy roads during transportation. The protective plate 21 is passively opened, resulting in a reduction in its protective effect. A groove is provided at the end of the fixing rod 22 furthest from the protective ring 18. A blocking block 25 is fixedly connected to the surface of the groove on the fixing rod 22. When the operator needs to open the protective plate 21, they pull the operating plate 23. The operating plate 23 moves the insertion rod 24. When the surface of the operating plate 23 contacts the blocking block 25, the insertion rod 24 completely disengages from the inner surface of the slot in the protective plate 21. At this point, the operator can open the protective plate 21. The blocking block 25 effectively prevents the operating plate 23 from slipping off the arc surface of the fixing rod 22 due to excessive force applied when pulling it. A spring 26 is fitted onto the arc surface of the fixing rod 22.The two ends of spring 26 are fixedly connected to operating plate 23 and protective ring 18, respectively. When the operator pulls operating plate 23, spring 26 is stretched, and operating plate 23 drives the insertion rod 24 to move. When the insertion rod 24 is completely disengaged from the surface of the slot of protective plate 21, the operator can open protective plate 21. After the operator completely closes protective plate 21, they release operating plate 23. The rebound force of spring 26 drives operating plate 23 to move, and operating plate 23 drives insertion rod 24 to move until insertion rod 24 is inserted into the surface of slot of protective plate 21. The rebound force of spring 26 achieves the effect of automatically inserting insertion rod 24, while preventing insertion rod 24 from disengaging from the surface of slot of protective plate 21, thus improving the stability of insertion rod 24 when fixing protective plate 21. The arc surface of rotating rod 20 is fitted with two torsion springs 27, the two ends of which are... Do not fix the button 1 to the U-shaped plate 19 and the protective plate 21. When the operator needs to open the protective plate 21, pull the operating plate 23. The operating plate 23 moves the insertion rod 24. When the insertion rod 24 is released from fixing the protective plate 21, the torque of the torsion spring 27 drives the protective plate 21 to rotate. The protective plate 21 drives the rotating rod 20 to rotate on the inner surface of the U-shaped plate 19 until the protective plate 21 is fully opened. The torque of the torsion spring 27 achieves the effect of automatically opening the protective plate 21, while keeping the protective plate 21 in the open state, thus facilitating the operator's use of the button 1. The surface of the button 1 is fixedly connected to an anti-slip pad 28, and the surface of the anti-slip pad 28 is fixedly connected to several anti-slip protrusions. The anti-slip pad 28 achieves the effect of anti-slip, increases the friction of the button 1 surface, and prevents the operator's hand from slipping when pressing the button 1.

[0029] Working principle: When the operator needs to protect button 1 with protective plate 21, pulling the operating plate 23 stretches the spring 26, causing the operating plate 23 to move the insertion rod 24. When the surface of the operating plate 23 contacts the blocking block 25, the insertion rod 24 moves to the appropriate position. Rotating the protective plate 21 causes the rotating rod 20 to rotate. When the surface of the protective plate 21 contacts the protective ring 18, the protective plate 21 completely covers the surface of button 1. Releasing the operating plate 23 causes the spring 26 to return, moving the operating plate 23 and the insertion rod 24. When the insertion rod 24 is inserted into the slot of the protective plate 21, it secures the protective plate 21. When the operator needs to open the protective plate 21, they pull the operating plate 23. When the insertion rod 24 is completely disengaged from the inner surface of the slot of the protective plate 21, the torque of the torsion spring 27 drives the protective plate 21 to rotate. The protective plate 21 drives the rotating rod 20 to rotate on the inner surface of the U-shaped plate 19 until the protective plate 21 is fully opened. At this time, the operator can press the button 1 normally. When pressing the button 1, the finger contacts the anti-slip pad 28 on the surface of the button 1, which has an anti-slip effect and achieves the effect of protecting the button 1. This avoids the situation where the button 1 is squeezed for a long time during the transportation of the pneumatic connector, which would cause the button 1 to lose its rebound force and fail to rebound normally.
