On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0033] See also Figure 1 , Figure 1 A schematic structural diagram of a vacuum chamber vacuuming and inflation combined quick connector provided in an embodiment of the present application.
[0034] like Figure 1 As shown, the vacuum chamber vacuuming and inflation combined quick connector includes a female connector 1 and a male connector 7 .
[0035] Specifically, the female connector 1 has a fixed installation structure at one end, which is connected to the vacuum chamber through a female connector end connecting thread 8 structure with a sealing function, wherein the female connector end connecting thread 8 structure with a sealing function is used to make the female connector 1 seamlessly connected to the vacuum chamber to maintain the vacuum environment of the chamber; the other end is a quick plug-in structure, which is centered on a spring locking bead 4 and is used to connect to a male connector 7, wherein the spring locking bead 4 automatically locks the corresponding slot on the male connector 7 under the action of an external force to form a locking force;
[0036] One end of the male connector 7 is connected to the female connector 1 through a quick-insertion structure, and the other end is provided with a male connector end connecting thread 13 structure with a sealing function, wherein the male connector end connecting thread 13 structure with a sealing function is used to make the male connector 7 seamlessly connected with the vacuum chamber to maintain the vacuum environment of the chamber; the other end is provided with a spring-type automatic locking structure matching the female connector 1, wherein when the male connector 7 is docked with the female connector 1, the spring locking bead 4 is automatically inserted into the preset slot of the male connector 7 to form a locking force.
[0037] In the embodiment of the present application, the female connector 1 integrates the airflow cavity opening and closing slider 9 mechanism, wherein the airflow cavity opening and closing slider 9 is equipped with a sealing ring for forming a density interface when connected with the male connector 7 to prevent gas leakage.
[0038] In the embodiment of the present application, the female connector 1 is also provided with an opening and closing slider reset spring 2 for controlling the airflow channel; when the male connector 7 is connected to the female connector 1, the airflow chamber opening and closing slider 9 automatically moves to the open position under the action of the opening and closing slider reset spring 2, allowing gas to flow smoothly; when the male connector 7 is disconnected from the female connector 1, the airflow chamber opening and closing slider 9 is easily led to the closed position under the action of the opening and closing slider reset spring 2, thereby blocking the airflow channel.
[0039] In the embodiment of the present application, an airflow chamber opening and closing slide post 11 is provided inside the male connector 7, wherein the airflow chamber opening and closing slide post 11 forms a linkage mechanism with the airflow chamber opening and closing slide head 9 of the female connector 1 to jointly control the on-off of the airflow channel; when the male connector 7 is connected to the female connector 1, the airflow chamber opening and closing slide post 11 moves under the action of external operation and the internal slide post buffer spring 10, pushing the airflow chamber opening and closing slide head 9 in the female connector 1 to open, allowing the gas to flow smoothly; when the male connector 7 is disconnected from the female connector, the airflow chamber opening and closing slide post 11 automatically resets, closes the airflow channel, and maintains the sealing state of the female connector 1 end.
[0040] In the embodiment of the present application, the airflow opening and closing slide post of the male connector 7 is internally provided with a buffer spring for pulling the airflow cavity opening and closing slide post 11 back to the initial position after the external operating force is removed.
[0041] In an embodiment of the present application, the connector further includes: a spring-type automatic locking structure, wherein the spring-type automatic locking structure includes a spring locking bead 4, a valve opening slide column 3, a valve locking slide head and a spring assembly.
[0042] On the one hand, the female connector 1 is introduced in detail.
[0043] The female connector 1 is designed as a fixed installation structure, which is firmly connected to the vacuum chamber through a threaded structure with a sealing function. The thread with a sealing function ensures seamless connection with the interior of the vacuum chamber, thereby effectively maintaining the vacuum environment of the chamber.
[0044] The other end adopts a quick plug-in structure, which is centered on a spring bead to achieve a quick and stable connection with the male connector. The design principle of the spring bead is that it can automatically lock the corresponding slot on the male connector 7 under the action of external force. Once the connection is completed, a locking force is formed to effectively prevent accidental disconnection caused by vibration or external impact, ensuring the reliability of the connection.
[0045] The female connector 1 also integrates the airflow chamber opening and closing slider 9 mechanism. The slider is equipped with a sealing ring, which can form a tight sealing interface when connected with the male connector 7 to prevent gas leakage. More importantly, the slider end is equipped with an opening and closing slider reset spring 2. This design makes the control of the airflow channel extremely simple and efficient. When the male connector 7 is connected to the female connector 1, the slider automatically moves to the open position under the action of the spring force, allowing the gas to flow smoothly; when the connection is disconnected, the slider quickly returns to the closed position under the action of the reset spring, immediately blocking the airflow channel, ensuring the sealing of the female connector 1 end, and effectively preventing the leakage of gas inside the chamber or the intrusion of external impurities.
[0046] On the other hand, the male connector 7 will be described in detail.
[0047] The plug-in structure of the male connector 7 and the female connector 1 realizes an efficient and reliable connection mechanism. One end of the plug-in structure is equipped with a threaded connection structure with a sealing function, which not only ensures a tight connection between the vacuum device or the special gas pipeline, but also effectively prevents gas leakage through its sealing performance, ensuring the stable operation of the system.
[0048] At the other end, the male connector 7 introduces a spring-type automatic locking structure that matches the female connector 1. This design makes full use of the elasticity and locking force of the spring; when the male connector 7 is docked with the female connector 1, the spring bead can automatically snap into the preset slot of the male connector 7 to achieve fast and stable locking. This locking mechanism is not only easy to operate, but also can withstand external forces from vibration and impact, effectively preventing accidental loosening of the quick-change connector and ensuring the long-term reliability of the connection.
[0049] Inside the male connector 7, a gas flow cavity opening and closing slide post 11 is carefully configured. The slide post forms a linkage mechanism with the gas flow cavity opening and closing slide head 9 in the female connector 1 to jointly control the opening and closing of the gas flow channel. When the male connector 7 is connected to the female connector 1, the gas flow cavity opening and closing slide post 11 moves under the action of external operation and the internal slide post buffer spring 10, pushing the gas flow cavity opening and closing slide head 9 in the female connector 1 to open, thereby allowing the gas to flow smoothly. Conversely, when the connection is disconnected, the slide post automatically resets, closing the gas flow channel and maintaining the sealing state of the female connector 1 end.
[0050] A buffer spring is also configured inside the airflow opening and closing slide column of the male connector 7. It can effectively alleviate the hard collision of the slide column when opening or closing the airflow cavity opening and closing slide head 9, reduce the damage to the quick-insert valve by the impact force, and also give the slide column the function of automatic reset. When the external operating force is removed, the buffer spring can quickly pull the slide column back to the initial position, ensuring that the male connector 7 and the female connector 1 can return to a reliable working state after each connection and disconnection.
[0051] On the other hand, the spring type automatic locking structure is introduced in detail.
[0052] The spring-type automatic locking structure is equipped with a spring locking bead 4, a valve opening slide column 3, a valve locking slide head and a precisely configured spring component, which together constitute an efficient and reliable quick connection and locking system.
[0053] During the connection process between the male connector 7 and the female connector 1, the spring-type automatic locking structure drives the airflow opening and closing slide column to move accurately to the opening position of the airflow opening and closing slider through the force applied from the outside, thereby triggering the opening action of the airflow opening and closing slider. As the airflow opening and closing slider is opened, the spring locking bead 4 is activated. Under the elastic force of the spring, the bead quickly and accurately snaps into the locking groove on the male connector 7 along the preset trajectory. This locking mechanism realizes a firm and stable connection between the male connector 7 and the female connector 1, and effectively prevents the connection from loosening or disconnecting due to external forces (such as vibration, impact, etc.).
[0054] On the other hand, the airflow control mechanism is introduced in detail.
[0055] The airflow channel control mechanism is used in the connection and disconnection process between the male connector 7 and the female connector 1. When the male connector 7 and the female connector 1 are connected, the mechanism can respond quickly and automatically open the airflow channel through the cooperation of the internal structure. In the connected state, the airflow channel remains open, allowing vacuum operation or injection and circulation of special gases according to actual needs.
[0056] When the male connector 7 is disconnected from the female connector 1, the connecting valve automatically closes the airflow channel driven by the internal spring, cutting off the connection between the internal system and the external environment. This ensures that the airflow pressure-maintaining function in the cavity at the end of the female connector 1 is achieved, that is, the gas pressure in the cavity is kept stable and constant. By closing the airflow channel, the sealing state of the female connector 1 end is further strengthened to prevent the intrusion of external impurities or gas.
[0057] In addition, the present application also provides an operating method for a vacuum chamber vacuuming and inflation combined quick connector, see Figure 2 , Figure 2 A flow chart of an operating method of a vacuum chamber vacuuming and inflation combined quick connector provided in an embodiment of the present application specifically includes the following steps.
[0058] Step S201: When the male connector and the female connector are connected, the valve opening slide column is driven to slide to the left due to the external force, triggering the built-in locking mechanism;
[0059] Step S202: Control the spring locking bead to automatically lock into the locking groove preset in the male connector during the movement of the airflow chamber opening and closing slide post, thereby locking the male connector and the female connector, wherein the airflow chamber opening and closing slide post is locked in position;
[0060] Step S203: the airflow chamber opening and closing slide column pushes the airflow chamber opening and closing slide head to move to the left end to the open position, controls the airflow channel to be in an open state, and performs a vacuum operation or an inflation operation of the vacuum chamber;
[0061] Step S204: After the vacuuming operation or the inflation operation of the vacuum chamber is completed, the valve opening slide column and the valve locking slide column are driven to slide to the right based on the external force, wherein the spring locking clamp releases the locking constraint on the male connector, separating the male connector from the female connector.
[0062] In the embodiment of the present application, the specific implementation of the connection operation is as follows:
[0063] When the male connector 7 is docked with the female connector 1, the valve opening slide column 3 is driven to slide to the left by the external force of the operator, triggering the built-in locking mechanism. The spring locking bead 4 automatically snaps into the preset locking groove of the male connector 7 during the movement of the slide column 3, realizing a stable locking connection between the male connector 7 and the female connector 1. To ensure the stability and reliability of this locking state, the locking slide column 6 locks the position of the valve opening slide column 3 under the elastic force of the valve locking spring 12 to prevent it from moving accidentally, thereby ensuring the alignment and firm connection between the female connector 1 and the male connector 7 in the working state.
[0064] At the same time, the airflow control mechanism inside the quick-change valve is also activated. The airflow cavity opening and closing slide post 11 pushes the airflow cavity opening and closing slide head 9 to move to the left end to the open position, so that the airflow channel is unblocked, indicating that the airflow channel between the male connector 7 and the female connector 1 is in an open state, allowing gas to flow.
[0065] At this point, the entire vacuum and inflation combined quick-change valve system is ready for operation and can perform vacuum or inflation operations according to system requirements to ensure the smooth progress of the fluid control process.
[0066] See also Figure 3 , Figure 3 A structural schematic diagram of the connection operation of a vacuum chamber vacuuming and inflation combined quick connector provided in an embodiment of the present application.
[0067] The specific implementation of the disconnect operation is as follows:
[0068] Under the external force applied by the operator, the valve opening slide column 3 and the valve locking slide column 6 are pushed to the right synchronously. At this time, the spring locking bead 4 overcomes its blocking force, thereby disengaging from the locking position of the male connector 7 and releasing the locking restraint on the male connector 7. Subsequently, the operator can safely remove the male connector 7 to the right to separate it from the female connector 1.
[0069] When the male connector 7 is completely separated from the female connector 1, the airflow cavity opening and closing slide post 11 automatically returns to the initial position in the working cavity of the male connector 7 under the elastic restoring force of the slide post buffer spring 10, ensuring that the slide post and its related components are in a standby state, ready for the next connection operation.
[0070] At the same time, the airflow cavity opening and closing slider 9 in the working cavity of the female connector 1 is driven by the elastic force of the opening and closing slider return spring 2 to quickly and reliably perform pressure-maintaining and airtight cavity sealing processing on the working cavity port of the female connector 1. This sealing operation not only blocks the possible gas leakage path, but also ensures that the working cavity connected to the female connector 1 end can maintain normal working pressure and environment in the separated state, thereby ensuring that the normal operation of other parts of the system is not affected.
