Description

Technical Field

[0001] This invention relates to the field of medical device connection technology, and more specifically, to a compressed air source connection device that can be quickly installed and disassembled. Background Technology

[0002] Pneumatic components such as cylinders, pneumatic pistons, and pneumatic platforms operate by directly connecting to external compressed air. The compressed air interface connects directly to the pneumatic component, and disassembly for inspection requires disconnecting the air hose. If the air hose is not pre-bleeded, or if the hose itself is difficult to bleed, there is a safety hazard. Existing air sources are connected to pneumatic components via quick-connect fittings, requiring frequent plugging and unplugging. After prolonged use, leaks and damage may occur, necessitating replacement of the entire pneumatic component. Furthermore, when pneumatic components transport liquid media, certain product processes require regular cleaning of the media chamber, which is integrated with the gas chamber, making disassembly inconvenient.

[0003] Therefore, how to solve the safety issues during the disassembly of pneumatic components is a problem that urgently needs to be addressed by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a compressed air source connection device that can be quickly installed and disassembled. By setting this connection device, the connection between the air source and the pneumatic components can be realized. Through mechanical locking protection, the situation of high-pressure gas ejecting the components will not occur.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A compressed air source connection device that can be quickly installed and disassembled includes:

[0007] An air intake base is provided with a mounting slot, and the bottom of the mounting slot has a through hole that communicates with the pneumatic components.

[0008] The intake assembly is detachably mounted in the mounting slot. The intake assembly can move along the height direction of the intake base. The intake assembly is rotatably connected to the intake base so that the intake assembly and the intake base can be locked or loosened. The bottom of the intake assembly matches the through hole so that a sealed intake chamber is formed between the intake assembly and the intake base. The intake assembly is provided with an intake port that communicates with the air source.

[0009] Preferably, the air intake assembly includes a gas chamber, which is a cavity structure. The gas chamber is detachably disposed in the mounting groove, and the outer periphery of the gas chamber abuts against the inner periphery of the mounting groove. The gas chamber cooperates with the air intake base to form a sealed air intake chamber. The gas chamber is provided with an air inlet that communicates with a gas source. The air intake chamber is used to store the gas supplied from the gas source.

[0010] Preferably, the intake assembly further includes a locking assembly, which includes:

[0011] An intake piston assembly is movably disposed within a gas chamber, and the intake piston assembly is rotatably connected to the gas chamber.

[0012] A locking element is provided on the outer periphery of the intake piston assembly, and the locking element is movably disposed along the axial direction of the intake piston assembly;

[0013] The nut is located on the intake piston assembly and on top of the locking member. The nut is used to adjust the position of the locking member along the axial movement of the intake piston assembly and to lock the locking member to the intake piston assembly.

[0014] Preferably, the intake piston assembly includes a piston rod, a piston moving sleeve that moves axially around the outer periphery of the piston rod, a piston moving disk around the outer periphery of the piston moving sleeve, and the outer periphery of the piston moving sleeve abuts against the inner periphery of the gas chamber. The piston moving sleeve has a first air hole in its circumferential direction, and a second air hole at the bottom of the piston moving sleeve that communicates with the pneumatic assembly. The first air hole and the second air hole communicate with each other.

[0015] Preferably, the top of the gas chamber is provided with a mounting hole that mates with the piston rod, and the top of the piston rod extends out of the top surface of the gas chamber and connects to the handle.

[0016] Preferably, the bottom of the piston moving sleeve is provided with an annular groove for installing a sealing ring.

[0017] Preferably, the piston rod has a circumferential thread at its top end, which extends axially along the piston rod to connect the nut to the piston rod.

[0018] Preferably, the locking element has an inverted U-shaped structure, and the middle of the locking element has an internal threaded hole that mates with the piston rod to achieve the connection between the piston rod and the locking element.

[0019] Preferably, the gas chamber is a cylindrical cavity structure, and the bottom outer periphery of the gas chamber is provided with a boss that mates with the mounting groove.

[0020] Preferably, the air intake base has a cylindrical structure, the mounting groove is an inverted T-shaped groove, and the top inner circumference of the air intake base is provided with a boss channel that mates with the boss, and the boss channel is connected to the mounting groove.

[0021] The quick-installation and disassembly compressed air source connection device provided by the present invention includes an air inlet base and an air inlet assembly. The connection device is set between the air source and the pneumatic assembly, dividing the air source and the pneumatic assembly into two independent parts, which facilitates the maintenance and cleaning of the pneumatic assembly. When the pneumatic assembly is conveying the medium, the connection between the pneumatic assembly and the air source can be disconnected at any time through the connection device.

[0022] Specifically, the bottom of the mounting slot has a through hole communicating with the pneumatic component. The mounting slot and through hole enable communication between the air intake base and the pneumatic component. The air intake component is detachably mounted in the mounting slot and can move along the height of the air intake base and rotate to connect with it. The air intake component can be quickly installed and removed simply by rotating and inserting / removing it. By rotating the air intake component, it can be locked or released from the air intake base, allowing the pneumatic component to be inflated and deflated without disconnecting the air source. The operation is simple, convenient, and quick. The bottom of the air intake component mates with the through hole to form a sealed air intake chamber between the air intake component and the air intake base. The air intake component has an air inlet communicating with the air source. Gas from the air source is introduced into the sealed air intake chamber through the air inlet and then forced into the pneumatic component for its application.

[0023] The compressed air source connection device, designed in the above manner, allows for quick installation and disassembly. Through mechanical design alone, it enables the inflation and deflation of pneumatic components. When installing the intake component, it is first moved downwards along the inner wall of the mounting groove. Once the bottom of the intake component is fully abutted against the through hole, the intake component is rotated to lock it to the intake base. Then, the intake chamber is inflated to a high-pressure state using the air source, and the gas is forced into the pneumatic component through the intake component and through the through hole to enable its operation. When the intake chamber is under high pressure and needs to be deflated, the intake component is rotated and pulled upwards. At this point, the bottom of the intake component disengages from the through hole, allowing the high-pressure air to automatically release, preventing the high-pressure gas from ejecting components and thus improving the safety of disassembling the pneumatic component.

[0033] 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.

[0034] It should be noted that the directional terms such as "up" and "down" in the following text are defined based on the accompanying drawings in the instruction manual.

[0035] The core of this invention is to provide a compressed air source connection device that can be quickly installed and disassembled. By setting this connection device, the connection between the air source and the pneumatic components can be realized. Through mechanical locking protection, the high-pressure gas will not cause the components to be ejected.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A quick-install and detachable compressed air source connection device includes an air inlet base 1 and an air inlet assembly 2. The connection device is located between the air source and the pneumatic assembly, dividing the air source and the pneumatic assembly into two independent parts, which facilitates the maintenance and cleaning of the pneumatic assembly. When the pneumatic assembly is conveying the medium, the connection between the pneumatic assembly and the air source can be disconnected at any time through the connection device.

[0037] Specifically, the bottom of the mounting groove 11 has a through hole 12 that communicates with the pneumatic component. The mounting groove 11 and the through hole 12 enable the connection between the air intake base 1 and the pneumatic component. The air intake component 2 is detachably mounted on the mounting groove 11. The air intake component 2 can move along the height direction of the air intake base 1 and rotate to connect with the air intake base 1. The air intake component 2 can be quickly installed and removed simply by rotating and inserting the pneumatic component. By rotating the air intake component 2, the air intake component 2 can be locked or released from the air intake base 1. Thus, the pneumatic component can be inflated and deflated without disconnecting the air source. The operation is simple, convenient and quick. The bottom of the air intake component 2 cooperates with the through hole 12 to form a sealed air intake chamber between the air intake component 2 and the air intake base 1. The air intake component 2 is provided with an air inlet 211 that communicates with the air source. The gas from the air source is introduced into the sealed air intake chamber through the air inlet 211 and then forced into the pneumatic component by the air intake component 2 for the application of the pneumatic component.

[0038] The air intake base 1 can be connected in any way as needed, without any restrictions, such as threads, flanges, clamps, etc., making it suitable for a wider range of scenarios.

[0039] The compressed air source connection device, which can be quickly installed and disassembled using the above method, can realize the inflation and deflation of pneumatic components through mechanical design alone. When installing the air intake component 2, first move the air intake component 2 downward along the inner wall of the mounting groove 11. After the bottom of the air intake component 2 is fully abutted against the through hole 12, rotate the air intake component 2 to lock the air intake component 2 with the air intake base 1. Then, inflate the air intake chamber to a high-pressure state through the air source, and force the gas into the pneumatic component through the air intake component 2 and the through hole 12 to make the pneumatic component run. When the air intake chamber is in a high-pressure state and needs to be deflated, rotate the air intake component 2 and pull it upward. At this time, the bottom of the air intake component 2 is disengaged from the through hole 12, so that the high-pressure air is automatically released. This prevents the high-pressure gas from causing the parts to be ejected, thereby improving the safety of disassembling the pneumatic component.

[0040] In the above embodiment, the air intake assembly 2 includes a gas chamber 21, which is a cavity structure. The gas chamber 21 is detachably disposed in the mounting groove 11, and the outer periphery of the gas chamber 21 abuts against the inner periphery of the mounting groove 11. The gas chamber 21 cooperates with the air intake base 1 to form a sealed air intake chamber. The gas chamber 21 is provided with an air inlet 211 that communicates with the gas source. The air intake chamber is used to store the gas introduced from the gas source.

[0041] It should be noted that when the intake assembly 2 needs to be installed, first align the gas chamber 21 with the mounting groove 11 on the intake base 1, and move it downward along the inner wall of the mounting groove 11. After the bottom end of the gas chamber 21 abuts against the bottom of the mounting groove 11, rotate it 30 degrees to form a sealed intake chamber between the gas chamber 21 and the intake base 1. When the intake assembly 2 needs to be disassembled, first rotate the intake assembly 2 30 degrees, and then lift the intake assembly 2 upward to disassemble the intake assembly 2.

[0042] In this embodiment, after the gas chamber 21 is installed downward along the mounting groove 11, it is rotated 30 degrees. However, in real life, there is no limit to the rotation angle of the gas chamber 21 after it is installed, as long as the above-mentioned technical effect can be achieved.

[0043] Optionally, the air intake component 2 can first move downward along the inner wall of the mounting groove 11. When the bottom of the air intake component 2 can no longer move downward, rotate the air intake component 2 to a position where it can continue to move downward along the inner wall of the mounting groove 11. Then continue to move the air intake component 2 downward until the bottom of the air intake component 2 abuts against the bottom of the mounting groove 11. Then rotate the air intake component 2 to lock the air intake component 2 and the air intake base 1.

[0044] In the above-described manner, the intake assembly 2 further includes a locking assembly, which includes an intake piston assembly 22, a locking member 23, and a nut 24. The intake piston assembly 22 is movably disposed within the gas chamber 21 and is rotatably connected to the gas chamber 21. The locking member 23 is disposed on the outer periphery of the intake piston assembly 22 and is movably disposed along the axial direction of the intake piston assembly 22. The nut 24 is disposed on the intake piston assembly 22 and located on top of the locking member 23. The nut 24 is used to adjust the position of the locking member 23 as it moves along the axial direction of the intake piston assembly 22 and to lock the locking member 23 and the intake piston assembly 22.

[0045] It is understandable that the intake and exhaust of the intake chamber are achieved through the cooperation of the intake piston assembly 22, the gas chamber 21, and the intake base 1. When installing this device, first fix the intake base 1 to the pneumatic assembly, then install the gas chamber 21 and the locking member 23 on the intake piston assembly 22. The locking member 23 is located at the top of the gas chamber 21, and its axial position on the intake piston assembly 22 is adjusted by the nut 24. The locking member 23 is then fixed in place by the nut 24. Align the assembled intake assembly 2 with the mounting groove 11 on the intake base 1 and move it downward along the mounting groove 11. When the bottom of the gas chamber 21 abuts against the bottom of the mounting groove 11, rotate the gas chamber 21 30 degrees. At the same time, the bottom of the intake piston assembly 22 engages with the through hole 12 at the bottom of the mounting groove 11. Then, continue to apply a downward force to the intake piston assembly 22 to drive the locking member 23 to continue moving downward until it abuts against the bottom of the mounting groove 11. Thus, the installation is completed.

[0046] When disassembly is required, first pull the intake piston assembly 22 upward to drive the locking member 23 to move upward along the mounting groove 11. After the locking member 23 moves upward to a certain distance, reverse the gas chamber 21 by 30 degrees and continue to pull the intake piston assembly 22 upward, thereby driving the gas chamber 21 and the locking member 23 away from the mounting groove 11, and completing the disassembly of the device.

[0047] The nut 24 serves three purposes: first, it connects and locks the locking member 23 and the intake piston assembly 22; second, it adjusts the relative height between the intake piston assembly 22 and the locking member 23 by adjusting the height, ensuring that after the locking member 23 is lowered into the groove, the bottom of the intake piston assembly 22 can fully enter the through hole 12 at the bottom of the mounting groove 11, thus achieving a sealing state; third, by adjusting the height of the nut 24, the bottom of the intake piston assembly 22 can disengage from the through hole 12 at the bottom of the mounting groove 11 before the locking member 23 leaves the mounting groove 11, allowing the intake chamber to release air in advance, thus ensuring the safety of the entire device in principle.

[0048] Furthermore, the intake piston assembly 22 includes a piston rod, and a piston moving sleeve that moves axially along the outer periphery of the piston rod. A piston moving disk is provided on the outer periphery of the piston moving sleeve, and the outer periphery of the piston moving sleeve abuts against the inner periphery of the gas chamber 21. The piston moving sleeve has a first air hole 221 in the circumferential direction, and the bottom of the piston moving sleeve has a second air hole 222 that communicates with the pneumatic assembly. The first air hole 221 and the second air hole 222 are in communication.

[0049] It should be noted that the piston moving sleeve moves along the axial direction of the piston rod to drive the piston moving disk to move synchronously along the axial direction of the piston rod, so that the piston moving disk moves up and down along the inner wall of the gas chamber 21. The gas chamber 21 is separated by the piston moving disk. The air in the gas chamber 21 increases in pressure under the supply of external air source. The compressed air flows downward through the first air hole 221 on the piston moving sleeve and flows out through the second air hole 222 into the working chamber of the pneumatic component below the air intake base 1.

[0050] In this embodiment, the first vent 221 is located around the piston moving sleeve, and the second vent 222 is located at the bottom of the piston moving sleeve. In real life, there are no restrictions on the number, position, or size of the first vent 221 and the second vent 222, as long as the above-mentioned technical effect can be achieved.

[0051] In the above embodiment, the top of the gas chamber 21 is provided with a mounting hole that mates with the piston rod, and the top of the piston rod extends out of the top surface of the gas chamber 21 and is connected to the handle 3.

[0052] Understandably, the piston rod is moved by the handle 3.

[0053] Based on the above embodiment, the bottom circumferential of the piston moving sleeve is provided with an annular groove for installing a sealing ring.

[0054] It should be noted that when the sealing ring at the bottom of the piston moving sleeve does not enter the through hole 12 of the air intake base 1, the gas chamber 21 is in a venting state; when the sealing ring enters the through hole 12 of the air intake base 1, the gas chamber 21 is in a pressurized state, and the sealing ring at the bottom of the piston moving sleeve can completely enter the through hole 12 of the air intake base 1, thereby achieving a sealing state.

[0055] Furthermore, as long as the sealing ring at the bottom of the piston moving sleeve is disengaged from the through hole 12 of the air intake base 1 before the locking part 23 leaves the mounting groove 11, the entire device can be vented in advance, thus ensuring safety.

[0056] In the above embodiment, the top end of the piston rod is circumferentially threaded, and the thread extends along the axial direction of the piston rod to achieve the connection between the nut 24 and the piston rod.

[0057] It is understood that in this embodiment, the nut 24 and the piston rod are connected by threads, but in real life, this is not a limitation, as long as the above-mentioned technical effect can be achieved.

[0058] In a preferred embodiment, the locking member 23 has an inverted U-shaped structure, and the middle part of the locking member 23 is provided with an internal threaded hole that mates with the piston rod to realize the connection between the piston rod and the locking member 23.

[0059] It should be noted that in this embodiment, the locking member 23 has an inverted U-shaped structure, and the locking member 23 is connected to the piston rod by threads and nuts 24. However, in real life, there are no restrictions on this, as long as the above-mentioned technical effects can be achieved.

[0060] In the above case, the gas chamber 21 is a cylindrical cavity structure, and the bottom outer periphery of the gas chamber 21 is provided with a boss 212 that mates with the mounting groove 11.

[0061] Understandably, the bottom end of the locking member 23 abuts against the top end of the boss 212. As the piston rod moves downward, the locking member 23 and the gas chamber 21 move downward synchronously. During the downward movement, the bottom end of the locking member 23 always abuts against the top end of the boss 212 on the gas chamber 21. When the gas chamber 21 moves down to the bottom of the mounting groove 11, the gas chamber 21 is rotated 30 degrees. At the same time, the bottom of the locking member 23 continues to move downward because there is no supporting structure, until the bottom end of the locking member 23 abuts against the bottom end of the mounting groove 11. At this time, the bottom ends of the locking member 23 and the gas chamber 21 are on the same horizontal plane, thus completing the installation.

[0062] When disassembling the device, first lift the piston rod upwards using handle 3, which will move the locking member 23 upwards. After the locking member 23 has moved to a certain height, reverse the gas chamber 21 by 30 degrees and continue to move the piston rod upwards using handle 3 until the gas chamber 21 is moved out of the mounting slot 11, thus completing the disassembly process of the device.

[0063] In the above embodiment, the air intake base 1 is a cylindrical structure, the mounting groove 11 is an inverted T-shaped groove, and the top inner circumference of the air intake base 1 is provided with a boss channel 13 that cooperates with the boss 212, and the boss channel 13 is connected to the mounting groove 11.

[0064] It should be noted that by setting the boss channel 13, the boss 212 can smoothly enter the mounting groove 11. During installation, align the boss 212 with the boss channel 13, push the piston rod downward, and drive the gas chamber 21 and the locking member 23 to move down synchronously. During the downward movement, the bottom end of the locking member 23 always abuts against the top end of the boss 212. When the bottom end of the gas chamber 21 moves down to the bottom of the mounting groove 11, rotate the gas chamber 21 30 degrees to make way for the downward movement of the locking member 23. At this time, the locking member 23 moves down into the groove of the mounting groove 11. The piston moving sleeve moves downward and the bottom of the piston moving sleeve aligns with the through hole 12 at the bottom of the mounting groove 11 to complete the seal. The sealing ring at the bottom of the piston moving sleeve abuts against the through hole 12, thereby sealing the intake piston assembly 22 and the gas chamber 21. At this time, under the action of compressed air inside the gas chamber 21, there is a restraining force between the gas chamber 21 and the intake base 1, thereby fixing the gas chamber 21 and preventing it from moving.

[0065] The locking member 23 cooperates with the boss channel 13 to realize the movement of the locking member 23.

[0066] It should be noted that in this embodiment, the air intake base 1 is a cylindrical structure. In real life, the air intake base 1 can be other shapes, and there is no limitation on this. Moreover, setting the mounting groove 11 as an inverted T-shape is a preferred embodiment, which makes it easy for the air intake base 1 to be fixed by rotation after being installed into the mounting groove 11. The operation is simple, convenient and quick. The top inner circumference of the air intake base 1 is provided with a channel 13 that cooperates with the boss 212, which makes it easy for the gas chamber 21 to be installed smoothly on the air intake base 1. There are no limitations on the above-mentioned installation and fixing methods, as long as the above technical effects can be achieved.

[0067] In summary, the compressed air source connection device provided by this invention allows for quick installation and disassembly. The boss 212 of the gas chamber 21 is aligned with the boss channel 13 on the air inlet base 1. After installation, it is rotated 30 degrees to clear the slot, and then the locking member 23 is installed. At this point, the gas chamber 21 is fixed. During disassembly, the locking member 23 is first pulled out of the mounting slot 11 of the air inlet base 1. Once the locking member 23 is pulled out, the second air hole 222 at the bottom of the piston moving sleeve disengages from the through hole 12 of the air inlet base 1, and the high-pressure air inside the gas chamber 21 automatically releases, preventing the high-pressure gas from causing the components to spring back.

[0068] The device provided in this application is a novel device for connecting air sources. Any air source can be directly connected. It can be installed between the air source and the main body of existing pneumatic components, separating the air source and the main body into two independent parts. This facilitates the maintenance and cleaning of the main body when conveying media (such as ink). The air source can be disconnected at any time. It can be used for flexible and rigid connections. Once the air source is connected to this device, it can be permanently connected without disassembly (and therefore will hardly be damaged). Inflation and de-inflation can be performed without unplugging or plugging in the air source, which is simple and convenient.
