Description

Technical Field

[0001] This utility model relates to the field of fluid connector technology, and more specifically, to a fluid connector joint. Furthermore, this utility model also relates to a fluid connector including the aforementioned fluid connector joint. Background Technology

[0002] When connecting liquid pipelines, fluid connectors are usually used. Fluid connectors typically have a shut-off valve inside. This valve shuts off the fluid connector before the connection is complete, preventing internal fluid leakage. At the same time, to prevent accidental operation of the valve body that could cause the shut-off valve to open unexpectedly, resulting in fluid leakage or accidental opening of the fluid connector, a locking mechanism is usually installed at the shut-off valve to lock its operation and prevent accidental operation.

[0003] In the process of developing this application, the inventors discovered that the prior art has at least the following problems:

[0004] The existing locking mechanism requires an additional control mechanism to open. During use, even after the fluid connector is connected, it is still necessary to unlock it through the control mechanism before the on / off state of the shut-off valve can be controlled. This increases the complexity of operating the fluid connector and prevents it from quickly connecting.

[0005] In summary, how to solve the problem of cumbersome connection operation after fluid connector connection is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a fluid connector fitting that can actively release the locking of the valve core when connected to the fluid connector plug, so that the fluid connector can be connected more quickly after the connection is completed, and reduce the cumbersome operation of the fluid connector.

[0007] Another objective of this invention is to provide a fluid connector that includes the above-mentioned fluid connector joint, has the same technical features, and can improve the same technical problems.

[0013] A locking part, which is slidably connected to the valve body, abuts against the floating member in the first locking position only when the locking part is in the second locking position, thereby preventing the floating member from disengaging from the first locking position;

[0014] The operating part of the locking part extends to the outside of the valve body. When the fluid connector connector is plugged into the fluid connector plug, the fluid connector plug abuts and drives the operating part to slide into the inside of the valve body, thereby driving the locking part to disengage from the second locking position.

[0015] Optionally, the floating member is provided with a connecting portion for engaging with the plugged-in fluid connector plug to restrict the separation of the fluid connector plug from the fluid connector joint;

[0016] When the valve core disengages from the preset working position, the valve core or its driving part abuts against and drives the floating member to disengage from the first locking position;

[0017] The engagement portion can disengage from the inserted fluid connector plug only when the floating member is in the first locking position, thereby enabling the fluid connector plug to be separated from the fluid connector joint.

[0018] Optionally, the valve core or its drive unit is coaxially fixedly provided with a cam portion, and the floating member abuts against the small-diameter end of the cam portion only when the floating member is in the first locking position, in order to restrict the rotation of the cam portion.

[0021] A floating pin is slidably connected to the valve body, and the sliding direction of the floating pin is perpendicular to that of the floating component. Only when the floating pin is in the second locking position does the floating pin abut against the floating component in the first locking position, thereby preventing the floating component from disengaging from the first locking position.

[0022] An end face pin is slidably connected to the valve body, and the sliding direction of the end face pin is perpendicular to that of the floating pin. The end face pin includes an operating part and a trajectory guide part. The trajectory guide part slides against the floating pin. When the operating part is pressed into the valve body, the trajectory guide part abuts and drives the floating pin to disengage from the second locking position.

[0023] Optionally, the sliding direction of the end face pin is consistent with the insertion direction of the fluid connector plug, and when the fluid connector plug is mated with the fluid connector joint, the fluid connector joint abuts and drives the operating part into the valve body; an end face pin reset elastic element is provided between the end face pin and the valve body to prevent the end face pin from entering the valve body;

[0029] The locking ball is slidably connected to the operating handle. When the operating handle is rotated, the locking ball can move in the locking ball groove. When the locking ball slides to the position of the countersunk hole, the locking ball can disengage from the operating handle and enter the countersunk hole.

[0030] The operating mechanism is used to drive the locking ball to disengage from the operating handle.

[0031] Optionally, the operating mechanism includes an operating pin and a locking pin that are slidably mounted to the operating handle, and the movement directions of the locking ball, the locking pin, and the operating pin are perpendicular to each other;

[0032] The end of the locking pin is provided with a wedge-shaped surface for abutting the locking ball. The locking pin pushes the locking ball to the third locking position only when the locking pin is in the third locking position.

[0033] The operating pin includes a pressing part and a guiding part.

[0064] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0065] The core of this utility model is to provide a fluid connector fitting that can actively release the locking of the valve core when connected to the fluid connector plug, so that the fluid connector can be connected more quickly after the connection is completed, reducing the cumbersome operation of the fluid connector.

[0066] Another core aspect of this invention is to provide a fluid connector that includes the aforementioned fluid connector joint, possessing the same technical features and effectively improving the same technical problems.

[0067] Example 1:

[0068] Please refer to Figures 2-5 A fluid connector fitting for mating with a fluid connector plug 2 to form a fluid connector;

[0069] Fluid connector fittings, including:

[0070] The valve body 14 has a fluid passage 143 and a valve core 142 that controls the opening and closing of the fluid passage 143. It is understood that the valve core 142 is preferably a ball core with a through flow channel hole. When the ball core moves to the open position, the flow channel hole of the ball core is aligned with the fluid passage 143 of the valve body 14. When the ball core moves to the closed position, the ball core blocks the fluid passage 143 to block the fluid transmission.

[0071] The floating member 17 is slidably connected to the valve body 14. Only when the floating member 17 is in the first locked position, the floating member 17 abuts against the valve core 142 or its drive part to lock the operation of the valve core 142 or its drive part. It can be understood that the valve core 142 or its drive part refers to the valve core 142 or the drive part of the valve core 142 of the fluid connector 1.

[0072] The locking part is slidably connected to the valve body 14. Only when the locking part is in the second locking position, the locking part abuts against the floating member 17 in the first locking position to prevent the floating member 17 from disengaging from the first locking position.

[0073] The operating part 151 of the locking part extends to the outside of the valve body 14. When the fluid connector 1 is plugged into the fluid connector plug 2, the fluid connector plug 2 abuts against the driving operating part 151 and slides into the inside of the valve body 14 to drive the locking part to disengage from the second locking position.

[0074] like Figure 4 and Figure 5 As shown, the floating member 17 abuts against the valve core 142 or its driving part, and the locking part locks the floating member 17 at the first locking position at point A, so that it completes the locking of the valve core 142 or its driving part at the preset working position. Since the locking part locks the floating member 17 when it is at the first locking position at point A, the floating member 17 has no possibility of disengaging from the first locking position, so the valve core 142 has no possibility of mis-connection.

[0075] Meanwhile, the operating part 151 of the locking part extends to the outside of the valve body 14. When the fluid connector 1 and the fluid connector plug 2 are plugged in, the fluid connector plug 2 can directly or indirectly abut against the driving part 151 to move, thereby controlling the locking part to release the floating member 17 from the first locking position, so that the valve core 142 or its driving part is in the unlocked state. That is, when the fluid connector 1 and the fluid connector plug 2 are plugged in, the locking of the valve core 142 in the preset working position is automatically released, and the user can directly operate the valve core 142 to open or close, thereby reducing the cumbersomeness of fluid connector operation.

[0076] In some embodiments, the floating member 17 is provided with a coupling portion for engaging with the plugged fluid connector plug 2 to restrict the separation of the fluid connector plug 2 from the fluid connector joint 1.

[0077] When the valve core 142 disengages from the preset working position, the valve core 142 or its driving part abuts against the driving floating member 17 and disengages from the first locking position.

[0078] Only when the floating member 17 is in the first locking position can the engagement part disengage from the inserted fluid connector plug 2, so that the fluid connector plug 2 can be separated from the fluid connector joint 1.

[0079] like Figures 6-9 The floating part 17 is provided with a connecting part. When the floating part 17 is disengaged from the first locking position at point A, its connecting part can engage and lock with the inserted fluid connector plug 2, so that the fluid connector joint 1 and the fluid connector plug 2 are locked and cannot be disengaged.

[0080] When the floating part 17 is in the first locking position, the joint can disengage from the inserted fluid connector plug 2, and at this time the fluid connector joint 1 and the fluid connector plug 2 can be unlocked and disengaged.

[0081] However, during use, when the valve core 142 is disengaged from the preset working position, the floating part 17 disengages from the first locking position, thereby locking the fluid connector joint 1 and the fluid connector plug 2 after insertion.

[0082] Only when the valve core 142 is in the preset working position can the floating part 17 be in the first locking position, that is, the fluid connector joint 1 and the fluid connector plug 2 can be unlocked and disengaged after plugging.

[0083] In practical use, the working position of the valve core 142 in the closed state is set to the preset working position. That is, when the valve core 142 is in the conducting state, the fluid connector 1 and the fluid connector plug 2 are locked and cannot be disengaged. Only when the valve core 142 is in the closed state can the fluid connector 1 and the fluid connector plug 2 be unlocked and disengaged, which effectively prevents the fluid connector 1 and the fluid connector plug 2 from disengaging when the fluid connector is in the conducting state.

[0084] The combination of the floating part 17 and the locking part locks the valve core 142 to the preset working position when the fluid connector 1 and the fluid connector plug 2 are not plugged in, thus preventing the valve core 142 from being turned on due to misoperation.

[0085] After the fluid connector 1 and the fluid connector plug 2 are plugged in, the fluid connector 1 and the fluid connector plug 2 are locked to prevent the valve core 142 from leaving the preset working position, i.e. the conducting state working position, and the fluid connector 1 and the fluid connector plug 2 from leaving the fluid connector, causing fluid leakage inside the fluid connector.

[0086] In some embodiments, the valve core 142 or its drive portion is coaxially fixedly provided with a cam portion 134. Only when the floating member 17 is in the first locking position, the floating member 17 abuts against the small diameter end of the cam portion 134 to limit the rotation of the cam portion 134.

[0087] like Figure 3 , Figure 4 and Figure 5As shown, the cam part 134 abuts against the floating part 17. When the cam part 134 rotates, it can drive the floating part 17 to slide, so that it slides between the non-first locking position and the first locking position, thus completing the engagement and disengagement of the joint and the fluid connector plug 2. When the valve core 142 disengages from the preset working position, the floating part 17 disengages from the first locking position and abuts against the outer peripheral wall of the non-small diameter end of the cam part 134. Therefore, the floating part 17 is suppressed by the cam part 134 and cannot return to the first locking position, that is, it cannot complete the unlocking of the joint and the fluid connector plug 2, thereby ensuring the locking stability of the fluid connector joint 1 and the fluid connector plug 2.

[0088] Meanwhile, when the locking part locks the floating member 17 in the first locking position, the floating member 17 can lock the cam part 134, that is, lock the working position of the valve core 142. Specifically, when the valve core 142 is in the preset working position and the floating member 17 is in the first locking position, the floating member 17 abuts against the outer peripheral wall of the small diameter end of the cam part 134. When the valve core 142 needs to disengage from the preset locking position, the cam part 134 needs to rotate. At this time, the floating member 17 disengages from the first locking position to abut against the outer peripheral wall of other positions of the cam part 134. However, at this time, the locking part locks the floating member 17, so the floating member 17 cannot disengage from the first locking position, that is, the cam part 134 cannot rotate, and thus the valve core 142 cannot disengage from the preset working position.

[0089] In some embodiments, the valve core 142 is coaxially fixed with the operating handle 13, and the cam portion 134 is coaxially fixed with the operating handle 13. Only when the valve core 142 is in a preset working position, the floating member 17 is in the first locking position and abuts against the outer peripheral wall of the small diameter end of the cam portion 134.

[0090] like Figure 4 and Figure 5 As shown, the cam portion 134 is mounted on the operating handle 13, which reduces the machining difficulty of the fluid connector joint 1 and helps to improve the machining accuracy of the cam portion 134, thereby ensuring the stability of the drive or locking between the cam portion 134 and the floating member 17.

[0091] In some embodiments, the locking portion includes:

[0092] The floating pin 16 is slidably connected to the valve body 14, and the sliding direction of the floating pin 16 is perpendicular to that of the floating member 17. Only when the floating pin 16 is in the second locking position, the floating pin 16 abuts against the floating member 17 in the first locking position to restrict the floating member 17 from disengaging from the first locking position.

[0093] The end face pin 15 is slidably connected to the valve body 14, and the sliding direction of the end face pin 15 is perpendicular to that of the floating pin 16. The end face pin 15 includes an operating part 151 and a trajectory guide part 152. The trajectory guide part 152 slides against the floating pin 16. When the operating part 151 is pressed into the valve body 14, the trajectory guide part 152 abuts against and drives the floating pin 16 to disengage from the second locking position.

[0094] like Figure 4 and Figure 5 As shown, the function of the locking part is realized by the combination design of floating pin 16 and end face pin 15. The sliding direction of floating pin 16 and floating part 17 is perpendicular, which can effectively reduce the movement margin of floating part 17 when locking in the first locking position, that is, effectively ensure the locking stability of floating part 17 when it is in the first locking position.

[0095] The sliding direction of the floating pin 16 is perpendicular to that of the end face pin 15, which can effectively reduce the movement margin of the floating pin 16 when it is locked in the second locking position, thus effectively ensuring the locking stability of the floating pin 16 when it is in the second locking position.

[0096] In some embodiments, the sliding direction of the end face pin 15 is consistent with the insertion direction of the fluid connector plug 2, and when the fluid connector plug 2 is mated with the fluid connector joint 1, the fluid connector joint 1 abuts against the drive operation part 151 and enters the valve body 14; an end face pin reset elastic element 153 is provided between the end face pin 15 and the valve body 14 to suppress the end face pin 15 from entering the valve body 14.

[0097] And / or, the sliding direction of the floating member 17 is consistent with the insertion direction of the fluid connector plug 2; a floating member reset elastic member 173 is provided between the floating member 17 and the valve body 14 to prevent the floating member 17 from disengaging from the first locking position.

[0098] And / or, the sliding direction of the floating pin 16 is perpendicular to that of the floating member 17, and a floating pin reset elastic member 162 is provided between the floating pin 16 and the valve body 14 to prevent the floating pin 16 from disengaging from the second locking position.

[0099] like Figure 4 and Figure 5 As shown, the sliding direction of the end face pin 15 and the floating part 17 is consistent with the insertion direction of the fluid connector 1 and the fluid connector plug 2. When the fluid connector 1 and the fluid connector plug 2 are inserted, the valve core 142 is automatically unlocked at the preset working position, and the fluid connector 1 and the fluid connector plug 2 are automatically locked.

[0100] At the same time, a floating part reset elastic element 173 is also provided to ensure that the floating part 17 always abuts against the cam part 134 and to prevent the floating part 17 from sliding freely.

[0101] It is also equipped with a floating pin reset elastic element 162, so that the floating pin 16 can return to the second locking position on its own after the external force is removed, thus locking the floating element 17.

[0102] It is also provided with an end face pin reset elastic element 153, so that the end face pin 15 can extend to the outside of the valve body 14 on its own after the external force is removed, and guide the floating pin 16 back to the second locking position to complete the locking of the floating element 17.

[0103] When the fluid connector 1 and the fluid connector plug 2 are disconnected, the end face pin 15, the floating pin 16 and the floating part 17 can automatically reset, lock the valve core 142 to the preset working position, and prevent the valve core 142 in the fluid connector 1 from being accidentally operated and turned on when it is not plugged in.

[0104] In some embodiments, the valve core 142 is coaxially fixedly provided with an operating handle 13, and the operating handle 13 is provided with a handle locking mechanism for locking the operation of the operating handle 13.

[0105] In certain application scenarios, even if the fluid connector 1 and the fluid connector plug 2 are successfully connected, accidental operation of the fluid connector can cause unnecessary consequences. Therefore, by setting a handle lock mechanism on the operating handle 13, the operating handle 13 is locked a second time. Only when the floating part 17 and the handle lock mechanism are unlocked at the same time can the operating handle 13 drive the valve core 142 to move away from the preset working position. Through double protection, the fluid connector is prevented from being accidentally connected.

[0106] In some embodiments, the handle locking mechanism includes a locking ball groove 141, a locking ball 133, and an operating mechanism;

[0107] The locking ball groove 141 is an arc-shaped groove, and the center of the arc is collinear with the rotation axis of the operating handle 13. Several sets of countersunk holes are provided in the locking ball groove 141.

[0108] The locking ball 133 is slidably connected to the operating handle 13. When the operating handle 13 is rotated, the locking ball 133 can move in the locking ball groove 141. When the locking ball 133 slides to the position of the countersunk hole, the locking ball 133 can disengage from the operating handle 13 and enter the countersunk hole.

[0109] The operating mechanism is used to drive the locking ball 133 to disengage from the operating handle 13.

[0110] like Figure 3 and Figure 10 As shown, the locking ball 133 is driven by the operating mechanism to disengage from the operating handle 13 and enter the countersunk hole, thereby achieving mutual locking between the operating handle 13 and the valve body 14. When the operating mechanism is released from driving the locking ball 133, the locking ball 133 can disengage from the countersunk hole and engage with the operating handle 13, and can move within the locking ball groove 141. That is, the operating handle 13 can rotate relative to the valve body 14, driving the valve core 142 to move.

[0111] In some embodiments, the operating mechanism includes an operating pin 131 and a locking pin 132 that are slidably mounted to the operating handle 13, and the movement directions of the locking ball 133, the locking pin 132 and the operating pin 131 are perpendicular to each other.

[0112] The end of the locking pin 132 is provided with a wedge-shaped surface for abutting against the locking ball 133. The locking pin 132 pushes the locking ball 133 to the third locking position only when the locking pin 132 is in the third locking position.

[0113] The operating pin 131 includes a pressing part and a guiding part. The pressing part extends to the outside of the operating handle 13, and the guiding part is slidably mounted with the locking pin 132. When the operating pin 131 is pressed, the guiding part drives the locking pin 132 to disengage from the third locking position.

[0114] like Figure 10 As shown, the combination of the vertically sliding operating pin 131 and the locking pin 132 enables the operating mechanism to drive the locking ball 133 to disengage from the operating handle 13. When the operating pin 131 drives the locking pin 132 to disengage from the third locking position at point C, the drive disappears, and the locking ball 133 can disengage from the countersunk hole and re-engage with the operating handle 13, and can move within the locking ball groove 141, that is, contact the locking of the operating handle 13 and the valve body 14.

[0115] In some embodiments, a locking pin reset elastic element 1321 is provided between the locking pin 132 and the operating handle 13 to prevent the locking pin 132 from disengaging from the third locking position.

[0116] And / or, an operating pin reset elastic element 1311 is provided between the operating pin 131 and the operating handle 13 for driving the operating pin 131 to reset after being pressed.

[0117] like Figure 10 As shown, by setting the locking pin reset elastic element 1321 and the operating pin reset elastic element 1311, the locking pin 132 and the operating pin 131 can automatically return to the position where the driving locking ball 133 is disengaged from the operating handle 13 when the external force is lost, thereby making the locking ball 133 always maintain the tendency to disengage from the operating handle 13 and enter the countersunk hole.

[0118] Meanwhile, when machining the slideways of the inner locking pin 132 and the operating pin 131 of the operating handle 13, through-hole machining is used, and a second plug 1322 and a first plug 1312 are respectively set at the end of the through hole to seal it, thereby reducing the machining difficulty of the operating handle 13.

[0119] This utility model also provides a fluid connector, including a fluid connector plug 2 and a fluid connector joint 1 of any one of the above. When the fluid connector joint 1 is plugged into the fluid connector plug 2, the fluid connector plug 2 slides against the drive operation part 151 into the interior of the valve body 14 to drive the locking part to disengage from the second locking position.

[0120] When fluid connector 1 is plugged into fluid connector plug 2, the locking of valve core 142 inside fluid connector 1 is automatically released, allowing it to move out of the preset working position. It is understood that fluid connector plug 2 can have the same structure as fluid connector 1.

[0121] Example 2:

[0122] Please refer to Figures 2-5 A fluid connector joint, comprising:

[0123] The valve body 14 has an internal fluid passage 143 and a valve core 142 that controls the opening and closing of the fluid passage 143. The valve core 142 or its drive part is coaxially fixed with a cam part 134. It is understood that the valve core 142 is preferably a ball core with a through flow channel hole. When the ball core moves to the open position, the flow channel hole of the ball core is aligned with the fluid passage 143 of the valve body 14. When the ball core moves to the closed position, the ball core blocks the fluid passage 143 to block the fluid transmission. The valve core 142 or its drive part refers to the valve core 142 or the drive part of the valve core 142 of the fluid connector 1.

[0124] The floating member 17 is slidably connected to the valve body 14. Only when the floating member 17 is in the first locked position, the floating member 17 abuts against the small diameter end of the cam portion 134 to limit the rotation of the cam portion 134.

[0125] The floating pin 16 is slidably connected to the valve body 14, and the sliding direction of the floating pin 16 is perpendicular to that of the floating member 17. Only when the floating pin 16 is in the second locking position, the floating pin 16 abuts against the floating member 17 in the first locking position, which is used to restrict the floating member 17 from disengaging from the first locking position.

[0126] like Figure 3 , Figure 4 and Figure 5As shown, the valve core 142 or its drive unit is coaxially provided with a cam part 134, and a floating member 17 is slidably provided inside the valve body 14. The sliding direction of the floating member 17 is perpendicular to the rotation axis of the cam part 134, and the floating member 17 can abut against the outer peripheral wall of the cam part 134. Only when the floating member 17 is in the first locking position at point A, the floating member 17 abuts against the outer peripheral wall of the small diameter end of the cam part 134. At this time, when the cam part 134 is driven to rotate, the abutment position between the cam part 134 and the floating member 17 will change from the outer peripheral wall of the small diameter end to the outer peripheral wall of the large diameter end. At this time, the floating member 17 will be driven to disengage from the first locking position at point A.

[0127] Meanwhile, a floating pin 16 is slidably disposed inside the valve body 14. When the floating pin 16 is in the second locking position at point B, the floating pin 16 can abut against the floating member 17 in the first locking position at point A to prevent the floating member 17 from disengaging from the first locking position at point A. That is, when the floating pin 16 is in the second locking position, it can lock the floating member 17 in the first locking position, thereby locking the cam part 134 in the first working position and suppressing the rotation of the cam part 134. When the floating pin 16 disengages from the second locking position, it releases the lock on the floating member 17 in the first locking position. At this time, the floating member 17 releases the restriction on the rotation of the cam part 134, causing the cam part 134 to disengage from the first working position, thereby driving the valve core 142 to rotate and change the conduction state of the fluid channel 143.

[0128] In the above process, when the cam part 134 is in the locked state, when the cam part 134 is driven to move, the direction of the force applied by the cam part 134 to the floating member 17 is perpendicular to the actual sliding direction of the floating member 17. Therefore, the movement margin of the cam part 134 in the locked state is effectively reduced. At the same time, the floating pin 16 is used to further lock the floating member 17 in its own sliding direction, reducing the movement margin of the floating member 17 in its own sliding direction in the locked state. Through the superposition of the double margin reduction, the movement margin of the valve core 142 in the locked state is further reduced, so that the locked state of the valve core 142 is stable, avoiding the decrease in sealing performance during operation and preventing fluid leakage.

[0129] In some embodiments, the sliding direction of the floating member 17 is parallel to the rotation axis of the cam portion 134, but the end face cam of the cam portion 134, the floating member 17 abuts against the cam surface of the end face cam, by changing the position of the cam surface abutting against the floating member 17, the floating member 17 is driven to slide along its own sliding direction, and then the position of the floating member 17 is locked to lock the rotation of the cam portion 134, that is, to lock the rotation of the valve core 142.

[0130] In some embodiments, the device further includes an end face pin 15, which is slidably connected to the valve body 14, and the sliding direction of the end face pin 15 is perpendicular to that of the floating pin 16.

[0131] The end face pin 15 includes an operating part 151 and a trajectory guide part 152. The operating part 151 extends to the outside of the valve body 14, and the trajectory guide part 152 slides against the floating pin 16. When the operating part 151 is pressed into the valve body 14, the trajectory guide part 152 abuts against and drives the floating pin 16 to disengage from the second locking position.

[0132] like Figure 3 , Figure 4 and Figure 5 As shown, the end face pin 15 is slidably installed with the valve body 14, and the sliding direction is perpendicular to the sliding direction of the floating pin 16. The end face pin 15 is provided with a trajectory guide part 152. Through the sliding contact between the trajectory guide part 152 and the floating pin 16, the movement of the end face pin 15 is converted into the movement of the floating pin 16. When the end face pin 15 is stationary, the end face pin 15 locks the position of the floating pin 16 to prevent the floating pin 16 from releasing the lock on the floating part 17, that is, to prevent the floating part 17 from locking the cam part 134.

[0133] Furthermore, the end face pin 15 includes an operating part 151 extending to the outside of the valve body 14. That is, the user can directly press the operating part 151 to drive the end face pin 15 to move, thereby driving the floating pin 16 to disengage from the second locking position, releasing the lock on the floating member 17, allowing the cam part 134 to change its contact position with the floating member 17, thereby allowing the cam part 134 to rotate, driving the valve core 142 to move, and changing the conduction state of the fluid passage 143.

[0134] In some embodiments, the sliding direction of the end face pin 15 is consistent with the insertion direction of the fluid connector joint 1, and when the fluid connector joint 1 mates with the fluid connector plug 2, the fluid connector plug 2 abuts against the drive operation part 151 and enters the valve body 14.

[0135] An end face pin reset elastic element 153 is provided between the end face pin 15 and the valve body 14 to prevent the end face pin 15 from entering the valve body 14.

[0136] like Figure 1 , Figure 2 and Figure 3 As shown, the fluid connector 1 and the fluid connector plug 2 are used together, and the sliding direction of the end face pin 15 is consistent with the insertion direction of the fluid connector 1. When the two are inserted, the mating end face of the fluid connector plug 2 abuts against the drive operation part 151 and enters the valve body 14, that is, through transmission, the cam part 134 and the valve core 142 are unlocked; when the fluid connector plug 2 is disengaged from the fluid connector 1, the end face pin 15 is automatically reset under the action of the end face pin reset elastic element 153, and the floating pin 16 is driven to slide to the second locking position.

[0137] In some embodiments, the sliding direction of the end face pin 15 is at an angle to the insertion direction of the fluid connector plug 2, such as 90°. By providing a guide surface at the free end of the operating part 151 for contact with the fluid connector plug 2, the movement of the insertion direction of the fluid connector plug 2 is converted into the movement of the end face pin 15 along its own sliding direction, and the above function can also be achieved. However, compared to the sliding direction of the end face pin 15 being consistent with the insertion direction of the fluid connector joint 1, this embodiment increases the radial dimension of the valve body 14, resulting in an increase in the overall space occupied by the fluid connector joint 1.

[0138] In some embodiments, the sliding direction of the floating member 17 is consistent with the insertion direction of the fluid connector 1;

[0139] A floating element reset elastic element 173 is provided between the floating element 17 and the valve body 14 to prevent the floating element 17 from disengaging from the first locking position.

[0140] like Figure 4 and Figure 5 As shown, the sliding direction of the floating member 17 is perpendicular to the rotation axis of the valve core 142, and the cam portion 134 is coaxially fixed with the valve core 142. In the design, the sliding direction of the floating member 17 is consistent with the insertion direction of the fluid connector 1, which can effectively reduce the radial dimension of the valve body 14, thereby reducing the volume of the fluid connector 1.

[0141] Meanwhile, by adding a floating part reset elastic element 173, the floating part 17 can always abut against the cam part 134, thereby improving the stability of the cam part 134 locking.

[0142] In some embodiments, the valve core 142 is coaxially fixed with an operating handle 13, and the cam portion 134 is coaxially fixed with the operating handle 13. Only when the valve core 142 is in the closed state, the floating member 17 is in the first locked position and abuts against the outer peripheral wall of the small diameter end of the cam portion 134.

[0143] like Figure 4 and Figure 5 As shown, the cam portion 134 is combined with the operating handle 13, that is, the valve core 142 is locked by locking the operating handle 13.

[0144] Furthermore, when the valve core 142 is in the closed state, the position of the floating member 17 is set to the first locking position. That is, when the floating member 17 locks the cam part 134, the valve core 142 is in the closed state, thereby preventing the valve core 142 from being accidentally turned on.

[0145] In some embodiments, when the valve core 142 is in both the cut-off and fully open positions, the floating member 17 is positioned in the first locking position. That is, two small-diameter ends are provided on the cam portion 134. When the valve core 142 is in the cut-off or fully open position, the two small-diameter ends of the cam portion 134 abut against the floating member 17 respectively, thereby locking the valve core 142 in both positions.

[0146] In some embodiments, the floating member 17 includes an abutment portion 171, which is cylindrical and is slidably mounted coaxially with a cylindrical guide hole in the valve body 14.

[0147] The free end of the contact portion 171 slides against the outer peripheral wall of the cam portion 134.

[0148] like Figure 6 As shown, the floating member 17 is an arc-shaped strip structure with a cylindrical abutment 171 vertically arranged in the middle. The abutment 171 is slidably installed with the cylindrical guide hole in the valve body 14. The cylindrical guide hole and the cylindrical abutment 171 are easy to process, ensuring a small radial movement margin between them. This avoids the overturning caused by the radial margin between the abutment 171 and the cylindrical guide hole when the cam part 134 drives the floating member 17 to slide, thereby reducing the movement margin of the floating member 17 in the locked state.

[0149] like Figure 6 As shown, guide portions 172 are provided at both ends of the floating member 17, which are slidably installed in cooperation with guide holes of corresponding shape inside the valve body 14, further suppressing the overturning tendency of the floating member 17, reducing the movement margin of the floating member 17 in the locked state, and further reducing the movement margin of the cam portion 134 and the valve core 142.

[0150] like Figure 6 As shown, the floating member 17 has elastic member fixing holes 175 at both ends for mounting the floating member reset elastic member 173, and the abutment part 171 is located in the middle of the floating member 17, so that when the floating member 17 is driven by the cam part 134, it can be balanced by force, avoid overturning, and ensure that the abutment part 171 is always in stable contact with the cam part 134.

[0151] In some embodiments, the side end of the floating member 17 is provided with a pin hole 174, and the pin portion 161 of the floating pin 16 in the second locking position can be inserted and fixed into the pin hole 174 only when the floating member 17 is in the first locking position.

[0152] like Figure 4 , Figure 5 and Figure 6As shown, a pin hole 174 is provided on the side end of the floating member 17 for engaging with the pin part 161 of the floating pin 16. That is, when the floating pin 16 is in the second locking position, the pin part 161 can be inserted into the pin hole 174 to lock the floating member 17. Compared with locking by directly abutting the floating member 17, it has higher locking stability.

[0153] In some embodiments, the sliding direction of the floating pin 16 is perpendicular to the insertion direction of the fluid connector 1, and a floating pin reset elastic element 162 is provided between the floating pin 16 and the valve body 14 to prevent the floating pin 16 from disengaging from the second locking position.

[0154] like Figure 4 and Figure 5 As shown, the sliding direction of the floating pin 16 is perpendicular to the insertion direction of the fluid connector 1, and its movement trajectory can be an arc-shaped trajectory. The center of the arc-shaped trajectory overlaps with the axis of the fluid connector 1, which reduces the radial dimension of the valve body 14.

[0155] At the same time, a floating pin reset elastic element 162 is added so that when the floating pin 16 loses external force, it can automatically slide to the second locking position to lock the floating element 17 and ensure the stability of the floating element 17 locking.

[0156] In some embodiments, the mating end face 11 of the valve body 14 is provided with a plug hole 111 and a plug rod 12;

[0157] The insertion rod 12 is perpendicular to the mating end face 11 and is used to be inserted into the fluid connector plug 2 that mates with the fluid connector joint 1.

[0158] The insertion hole 111 is used to accommodate the insertion part of the fluid connector plug 2.

[0159] like Figure 2 and Figure 3 As shown, a plug hole 111 and a plug rod 12 are provided on the mating end face 11 of the valve body 14 to improve the convenience of plugging and fixing the fluid connector joint 1 and the fluid connector plug 2.

[0160] This utility model also provides a fluid connector including the above-mentioned fluid connector joint 1, including a fluid connector plug 2 and any of the above-mentioned fluid connector joint 1. When the fluid connector plug 2 is inserted into the fluid connector joint 1, the fluid connector plug 2 can directly abut against the drive or drive the floating pin 16 to disengage from the second locking position through the transmission mechanism.

[0161] like Figure 1 and Figure 2As shown, the fluid connector 1 can be plugged into the fluid connector plug 2. During the plugging process, the fluid connector plug 2 can abut against the drive operation part 151 and enter the valve body 14, that is, drive the end face pin 15 to slide, guide the floating pin 16 to disengage from the second locking position, and unlock the floating part 17 in the first locking position, that is, realize the unlocking of the cam part 134 and the valve core 142. In other words, the valve core 142 inside the fluid connector 1 is automatically unlocked through the plugging of the fluid connector 1 and the fluid connector plug 2.

[0162] Example 3:

[0163] Please refer to Figures 6-9 A fluid connector fitting for mating with a fluid connector plug 2;

[0164] Fluid connector 1, comprising:

[0165] The valve body 14 has a fluid passage 143 and a valve core 142 that controls the opening and closing of the fluid passage 143 inside.

[0166] The floating part 17 has a connecting part for engaging with the fluid connector plug 2 to prevent the fluid connector plug 2 from separating from the fluid connector joint 1.

[0167] When the valve core 142 disengages from the preset working position, the valve core 142 or its driving part abuts against the driving floating member 17 and disengages from the first locking position.

[0168] Only when the floating member 17 is in the first locking position can the engagement part disengage from the inserted fluid connector plug 2, so that the fluid connector plug 2 can be separated from the fluid connector joint 1.

[0169] like Figure 7 , Figure 8 and Figure 9 As shown, when fluid connector 1 and fluid connector plug 2 are inserted, after they are inserted along their own axis, they are rotated by a preset angle so that fluid connector 1 completes the connection with fluid connector plug 2. When unlocking, they need to be rotated in the opposite direction first to lock fluid connector 1 to fluid connector plug 2. Then the two move away from each other along their own axis to complete the disconnection of the fluid connector.

[0170] like Figure 6 As shown, the surface of the floating part 17 is provided with a plug rod locking hole 176. As the floating part 17 slides in the valve body 14, the plug rod locking hole 176 can move along its own axis.

[0171] like Figure 8 and Figure 9As shown, when the fluid connector is connected, the axis of the insertion part of the fluid connector plug 2 overlaps with the axis of the locking hole 176 of the plug rod. When the valve core 142 disengages from the preset working position, the valve core 142 or its driving part abuts against the driving floating part 17 to disengage from the first locking position at point A. At this time, the insertion part of the fluid connector plug 2 and the locking hole 176 of the plug rod partially overlap in the axial direction, that is, the insertion part and the locking hole 176 of the plug rod cannot move radially, which restricts the rotation of the fluid connector joint 1 and the fluid connector plug 2, and thus cannot unlock the fluid connector joint 1 and the fluid connector plug 2. If the preset working position of the valve core 142 is changed, the valve core 142 will be locked out of the first locking position at point A. When the valve core 142 is in the closed position, the fluid connector 1 and the fluid connector plug 2 will not be able to unlock when the valve core 142 is open, that is, the fluid connector cannot be disconnected, thus avoiding leakage of internal fluid. Only when the valve core 142 is closed, the floating part 17 is driven by the valve core 142 or its driving part to return to the first locking position at point A. At this time, the insertion part of the fluid connector plug 2 and the locking hole 176 of the insertion rod have no overlap in the axial direction, and the two can move radially, that is, the fluid connector 1 and the fluid connector plug 2 can rotate relative to each other, thereby unlocking the fluid connector 1 and the fluid connector plug 2.

[0172] It is worth noting that the axis of the insertion part of the fluid connector plug 2 and the axis of the locking hole 176 of the insertion rod should be parallel to and not overlap with the rotation axis of the fluid connector joint 1 and the fluid connector plug 2.

[0173] In some embodiments, after the floating member 17 disengages from the first locking position at point A, it can extend to the outside of the valve body 14 and directly engage with the mating fluid connector plug 2, thereby suppressing the relative rotation of the fluid connector joint 1 and the fluid connector plug 2, and thus achieving the above-mentioned function. At this time, the sliding direction of the floating member 17 can be the insertion direction of the fluid connector joint 1 and the fluid connector plug 2, or it can be a direction perpendicular to the insertion direction of the fluid connector joint 1 and the fluid connector plug 2.

[0174] In some embodiments, a cam portion 134 is coaxially fixedly provided on the valve core 142 or its drive portion, and the cam portion 134 abuts against the floating member 17.

[0175] Only when the valve core 142 is in the preset working position can the outer peripheral wall of the small diameter end of the cam portion 134 abut against the floating member 17 in the first locking position.

[0176] like Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, when the valve core 142 is in the preset working position, the small diameter end of the cam part 134 abuts against the floating part 17. At this time, the floating part 17 is in the first locking position at point A. At this time, the plug rod locking hole 176 in the floating part 17 does not overlap with the plug part of the fluid connector plug 2 in the axial direction, that is, there is no locking between the fluid connector connector 1 and the fluid connector plug 2.

[0177] When the valve core 142 is disengaged from the preset working position, the large diameter end of the cam part 134 abuts against the floating part 17. At this time, the floating part 17 will disengage from the first locking position at point A. The plug-in rod locking hole 176 in the floating part 17 will partially overlap with the plug-in part of the fluid connector plug 2 in the axial direction. The two will not be able to generate relative movement along their own radial direction, that is, the fluid connector connector 1 and the fluid connector plug 2 are locked.

[0178] Furthermore, when fluid connector 1 and fluid connector plug 2 are locked, the floating member 17 cannot return to the first locked position due to the abutment of the large-diameter end of the cam portion 134, thus preventing the fluid connector 1 and fluid connector plug 2 from being unlocked. Only when the valve core 142 returns to the preset working position can the floating member 17 abut against the small-diameter end of the cam portion 134, that is, the floating member 17 returns to the first locked position, thereby unlocking the fluid connector 1 and fluid connector plug 2. This ensures the stability of the locking of the fluid connector 1 and fluid connector plug 2 and effectively prevents the fluid connector 1 and fluid connector plug 2 from disconnecting when the valve core 142 has not returned to the preset working position.

[0179] In some embodiments, the sliding direction of the floating member 17 is consistent with the insertion direction of the fluid connector joint 1 and the fluid connector plug 2, which effectively reduces the radial dimension of the fluid connector joint 1. However, in some embodiments, the sliding direction of the floating member 17 is perpendicular to the insertion direction of the fluid connector joint 1 and the fluid connector plug 2, and parallel to the rotation axis of the valve core 142. In this case, the cam portion 134 should be an end face cam.

[0180] In some embodiments, the floating member 17 includes an abutment portion 171, which is cylindrical and is slidably mounted coaxially with a cylindrical guide hole in the valve body 14.

[0181] The free end of the contact portion 171 slides against the outer peripheral wall of the cam portion 134.

[0182] like Figure 6As shown, the floating member 17 is an arc-shaped strip structure with a cylindrical abutment 171 vertically arranged in the middle. The abutment 171 is slidably installed with the cylindrical guide hole in the valve body 14. The cylindrical guide hole and the cylindrical abutment 171 are easy to process, ensuring a small radial movement allowance between them. This allows the axis of the plug-in rod locking hole 176 to always overlap with the axis of the plug-in part of the fluid connector plug 2 when the floating member 17 slides, ensuring that they can be inserted smoothly and reducing interference when the plug-in part and the floating member 17 move axially relative to each other.

[0183] In some embodiments, the fluid connector 1 further includes a floating pin 16, which is slidably connected to the valve body 14 and the sliding direction of the floating pin 16 is perpendicular to that of the floating member 17. Only when the floating pin 16 is in the second locking position, the floating pin 16 abuts against the floating member 17 in the first locking position to restrict the floating member 17 from disengaging from the first locking position.

[0184] A floating pin reset elastic element 162 is provided between the floating pin 16 and the valve body 14 to prevent the floating pin 16 from disengaging from the second locking position.

[0185] like Figure 4 and Figure 5 As shown, by adding a floating pin 16 to lock the floating member 17 in the first locking position, and then by locking the cam part 134 through the floating member 17 in the first locking position, the working position of the valve core 142 is locked. The locking of the valve core 142 is linked with the locking between the fluid connector joint 1 and the fluid connector plug 2. That is, the floating member 17 has the ability to lock both the working position of the valve core 142 and the fluid connector. The fluid connector joint 1 and the fluid connector plug 2 can only be disengaged when the valve core 142 is in the preset working position. When the floating pin 16 is in the second locking position at point B, the valve core 142 is locked in the preset working position. This allows the fluid connector joint 1 to simultaneously prevent the valve core 142 from being opened by accident and to prevent the valve core 142 from being disengaged from the fluid connector plug 2 when it is opened.

[0186] In some embodiments, the fluid connector 1 further includes an end face pin 15, which is slidably connected to the valve body 14, and the sliding direction of the end face pin 15 is perpendicular to that of the floating pin 16.

[0187] The end face pin 15 includes an operating part 151 and a trajectory guide part 152. The operating part 151 extends to the outside of the valve body 14, and the trajectory guide part 152 slides against the floating pin 16. When the operating part 151 is pressed into the valve body 14, the trajectory guide part 152 abuts against and drives the floating pin 16 to disengage from the second locking position.

[0188] like Figure 1 , Figure 2 and Figure 3As shown, the fluid connector 1 and the fluid connector plug 2 are used together, and the sliding direction of the end face pin 15 is consistent with the insertion direction of the fluid connector 1 and the fluid connector plug 2. When the two are inserted, the mating end face of the fluid connector plug 2 abuts against the drive operation part 151 and enters the valve body 14, that is, through transmission, the cam part 134 and the valve core 142 are unlocked; when the fluid connector plug 2 is disengaged from the fluid connector 1, the end face pin 15 is automatically reset under the action of the end face pin reset elastic element 153, and the floating pin 16 is driven to slide to the second locking position.

[0189] This means that when fluid connector 1 and fluid connector plug 2 are plugged in, the preset working position lock of valve core 142 is automatically released, and when valve core 142 is disengaged from the preset working position, fluid connector 1 and fluid connector plug 2 are automatically locked in place.

[0190] In some embodiments, the sliding direction of the end face pin 15 is at an angle to the insertion direction of the fluid connector plug 2, such as 90°. By providing a guide surface at the free end of the operating part 151 for contact with the fluid connector plug 2, the movement of the insertion direction of the fluid connector plug 2 is converted into the movement of the end face pin 15 along its own sliding direction, and the above function can also be achieved. However, compared to the sliding direction of the end face pin 15 being consistent with the insertion direction of the fluid connector joint 1, this embodiment increases the radial dimension of the valve body 14, resulting in an increase in the overall space occupied by the fluid connector joint 1.

[0191] In some embodiments, the operating part 151 is provided with a contact surface for abutting against the fluid connector plug 2;

[0192] When the fluid connector plug 2 is inserted into the fluid connector joint 1, the fluid connector plug 2 drives the operating part 151 to enter the valve body 14 through the contact surface.

[0193] When the sliding direction of the end face pin 15 is at an angle to the insertion direction of the fluid connector joint 1 and the fluid connector plug 2, such as when they are perpendicular, the movement of the fluid connector joint 1 and the fluid connector plug 2 along the insertion direction is converted into the movement of the end face pin 15 along its own sliding direction by providing a guiding contact surface at the end of the operating part 151. This enables the end face pin 15 to drive the floating pin 16, thereby locking or unlocking the floating part 17.

[0194] In some embodiments, the sliding direction of the end face pin 15 is consistent with the insertion direction of the fluid connector plug 2, and when the fluid connector plug 2 is mated with the fluid connector connector 1, the mating end face of the fluid connector plug 2 abuts against the drive operation part 151 and enters the valve body 14; an end face pin reset elastic element 153 is provided between the end face pin 15 and the valve body 14 to suppress the end face pin 15 from entering the valve body 14.

[0195] And / or, the sliding direction of the floating member 17 is consistent with the insertion direction of the fluid connector plug 2; a floating member reset elastic member 173 is provided between the floating member 17 and the valve body 14 to prevent the floating member 17 from disengaging from the first locking position.

[0196] like Figure 3 , Figure 4 and Figure 5 As shown, the sliding direction of the end face pin 15 is consistent with the insertion direction of the fluid connector 1. When the two are inserted, the mating end face of the fluid connector plug 2 abuts against the drive operation part 151 and enters the valve body 14. That is, through transmission, the cam part 134 and the valve core 142 are unlocked. When the fluid connector plug 2 is disengaged from the fluid connector 1, the end face pin 15 automatically resets under the action of the end face pin reset elastic element 153, driving the floating pin 16 to slide to the second locking position.

[0197] like Figure 4 and Figure 5 As shown, the sliding direction of the floating part 17 is consistent with the insertion direction of the fluid connector 1, which can effectively reduce the radial dimension of the valve body 14, thereby reducing the volume of the fluid connector 1.

[0198] Meanwhile, by adding a floating part reset elastic element 173, the floating part 17 can always abut against the cam part 134, thereby improving the stability of the cam part 134 locking.

[0199] In some embodiments, the sliding direction of the floating member 17 is consistent with the insertion direction of the fluid connector 1;

[0200] The mating end face 11 of the fluid connector 1 is provided with a plug hole 111 for the plug portion of the fluid connector plug 2 to be plugged in.

[0201] The insertion hole 111 is an arc-shaped elongated hole. The center of the arc of the insertion hole 111 overlaps with the rotation axis of the fluid connector plug 2 when it is inserted. A limiting mechanism is provided at the position where the insertion hole 111 and the connecting part overlap along the insertion axis of the fluid connector plug 2 to prevent the connecting part from disengaging from the insertion hole 111.

[0202] like Figure 2 and Figure 3As shown, the mating end face 11 of the fluid connector 1 is provided with a plug hole 111 for the plug portion of the fluid connector plug 2 to be inserted. The plug hole 111 is set as an arc-shaped elongated hole, so that after the fluid connector 1 and the fluid connector plug 2 are inserted axially, the plug portion can move along the length direction of the plug hole 111, that is, the fluid connector 1 and the fluid connector plug 2 can rotate around their own axis. When the plug portion rotates to the position where the plug hole 111 has a limiting mechanism, the fluid connector 1 and the fluid connector plug 2 will not be able to move coaxially along the insertion direction, causing the plug portion to disengage from the plug hole 111, thus achieving locking of the fluid connector 1 and the fluid connector plug 2 along the insertion direction. At this time, the locking of the plug portion by the floating member 17 will suppress the movement of the plug portion in the plug hole 111, that is, suppress the rotation of the fluid connector 1 and the fluid connector plug 2 around the axis, thus achieving locking of all degrees of freedom of the fluid connector 1 and the fluid connector plug 2.

[0203] In some embodiments, the mating end face 11 is vertically provided with a plug rod 12 for plugging into the plug hole of the fluid connector plug 2;

[0204] The plug rod 12 includes a relatively fixed rod portion 121 and a head 122. The axial cross-sectional area of ​​the head 122 is larger than the axial cross-sectional area of ​​the rod portion 121, which is used to limit the head 122 by the limiting mechanism of the plug hole of the fluid connector plug 2.

[0205] like Figure 2 and Figure 3 As shown, a plug rod 12 is provided on the mating end face 11 as the plug part of the fluid connector connector 1, which is used to plug into and / or lock with the plug hole in the fluid connector plug 2. Through the structural design of the rod part 121 and the head 122, after the plug rod 12 enters the plug hole of the fluid connector plug 2, the relative position of the fluid connector connector 1 and the fluid connector plug 2 can be locked along the plugging direction by the relative rotation of the fluid connector connector 1 and the fluid connector plug 2.

[0206] This utility model also provides a fluid connector including the above-mentioned fluid connector joint, including a fluid connector plug 2 and any one of the above fluid connector joints. When the fluid connector joint 1 is plugged into the fluid connector plug 2 and the valve core 142 of the fluid connector joint 1 is disengaged from the preset working position, the fluid connector plug 2 and the fluid connector joint 1 are engaged.

[0207] Preferably, the fluid connector plug 2 has the same structure as the fluid connector joint 1;

[0208] When fluid connector 1 and fluid connector plug 2 are plugged in, both have internal locking structures to prevent the valve core 142 in fluid connector 1 or fluid connector plug 2 from being in a non-preset working position when they are disengaged.

[0209] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
