Description

Technical Field

[0001] The present invention relates to the technical field of fluid connectors, and more particularly to a fluid connector joint. In addition, the present invention also relates to a fluid connector comprising the fluid connector joint. Background Art

[0002] When connecting liquid pipelines, a fluid connector is usually required for connection, and a shut-off valve is usually provided inside the fluid connector. When the connector of the fluid connector is not fully plugged in, the connector of the fluid connector is shut off to prevent internal fluid leakage. At the same time, in order to avoid misoperation of the valve body, which may cause the shut-off valve to be accidentally opened, resulting in fluid leakage or accidental connection of the fluid connector, a locking mechanism is usually provided at the shut-off valve to lock the shut-off valve action and avoid misoperation of the shut-off valve.

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

[0004] The opening of the existing locking mechanism requires the addition of an additional control mechanism. During use, even if the fluid connector is connected, it still needs to be unlocked by the control mechanism before the shut-off valve can be controlled, which increases the complexity of operating the fluid connector and prevents the fluid connector from being quickly connected.

[0005] In summary, how to solve the problem of cumbersome conduction operation after the fluid connector is connected is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a fluid connector joint that can actively release the lock of the valve core when connected to the fluid connector plug, so that the fluid connector can be conducted more quickly after the connection is completed, reducing the cumbersomeness of the operation of the fluid connector.

[0024] And / or, the sliding direction of the floating member is consistent with the plugging direction of the fluid connector plug; a floating member reset elastic member is provided between the floating member and the valve body, for preventing the floating member from disengaging from the first locking position;

[0025] And / or, the floating pin is perpendicular to the sliding direction of the floating member, and a floating pin reset elastic member is provided between the floating pin and the valve body for preventing the floating pin from being disengaged from the second locking position.

[0026] Optionally, an operating handle is coaxially fixedly provided on the valve core, and a handle locking mechanism is provided inside the operating handle for locking the movement of the operating handle.

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

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0065] The core of the present invention is to provide a fluid connector joint that can actively release the lock on the valve core when connected to the fluid connector plug, so that the fluid connector can be conducted more quickly after the connection is completed, reducing the cumbersomeness of the operation of the fluid connector.

[0066] Another core of the present invention is to provide a fluid connector including the above-mentioned fluid connector joint, which has the same technical features and can effectively improve the same technical problems.

[0067] Example 1:

[0068] Please refer to Figure 2-Figure 5 , a fluid connector joint, used to be plugged into the fluid connector plug 2 to form a fluid connector;

[0069] Fluid connector fittings, including:

[0070] The valve body 14 is provided with a fluid passage 143 and a valve core 142 for controlling the opening and closing of the fluid passage 143. It is understood that the valve core 142 is preferably a ball core, which is provided with a through-flow hole. When the ball core moves to the open position, the flow 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 prevent 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 locking position, the floating member 17 abuts against the valve core 142 or its driving portion to lock the movement of the valve core 142 or its driving portion. It can be understood that the valve core 142 or its driving portion refers to the valve core 142 or the driving portion of the valve core 142 of the fluid connector joint 1.

[0072] A locking portion is slidably connected to the valve body 14. Only when the locking portion is in the second locking position does the locking portion abut against the floating member 17 in the first locking position, thereby preventing the floating member 17 from leaving the first locking position.

[0073] The operating portion 151 of the locking portion extends to the outside of the valve body 14. When the fluid connector joint 1 is plugged into the fluid connector plug 2, the fluid connector plug 2 abuts against the driving operating portion 151 to slide into the inside of the valve body 14, thereby driving the locking portion out of 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 portion, and the locking portion locks the floating member 17 in the first locking position at point A, thereby completing the locking of the valve core 142 or its driving portion in the preset working position. Since the locking portion locks the floating member 17 when it is in the first locking position at point A, the floating member 17 cannot be separated from the first locking position, and the valve core 142 cannot be mis-opened.

[0075] At the same time, the operating part 151 of the locking part extends to the outside of the valve body 14. When the fluid connector joint 1 and the fluid connector plug 2 are plugged in, the fluid connector plug 2 can directly or indirectly abut the driving operating part 151 to move, thereby controlling the locking part to release the lock of the floating part 17 in the first locking position, that is, the valve core 142 or its driving part is in an unlocked state, that is, when the fluid connector joint 1 and the fluid connector plug 2 are completed, the lock of the valve core 142 in the preset working position is automatically released, and the user can directly operate the on and off of the valve core 142, thereby reducing the tediousness of the fluid connector operation.

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

[0077] When the valve core 142 is released from the preset working position, the valve core 142 or its driving portion abuts against and drives the floating member 17 to release from the first locking position;

[0078] Only when the floating member 17 is in the first locking position can the coupling portion be disengaged from the plugged fluid connector plug 2 , so as to enable the fluid connector plug 2 to be separated from the fluid connector joint 1 .

[0079] like Figure 6-Figure 9 The floating member 17 is provided with a coupling portion. When the floating member 17 is released from the first locking position at point A, the coupling portion can be coupled and locked with the plugged fluid connector 2, so that the fluid connector joint 1 and the fluid connector plug 2 are locked and cannot be separated.

[0080] Only when the floating member 17 is in the first locking position can the joint be separated from the plugged fluid connector plug 2 , and only then can the fluid connector joint 1 and the fluid connector plug 2 be unlocked and separated.

[0081] However, in use, when the valve core 142 is out of the preset working position, the floating member 17 is out of the first locking position, that is, the fluid connector joint 1 and the fluid connector plug 2 are locked after plugging;

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

[0083] In actual use, the working position of the valve core 142 in the cut-off state is set to the preset working position, that is, when the valve core 142 is in the on state, the fluid connector joint 1 and the fluid connector plug 2 are locked and cannot be disengaged. Only when the valve core 142 is in the cut-off state can the fluid connector joint 1 and the fluid connector plug 2 be unlocked and disengaged, effectively preventing the fluid connector joint 1 and the fluid connector plug 2 from being disengaged when the fluid connector is in the on state.

[0084] That is, the combination of the floating member 17 and the locking portion locks the valve core 142 in a preset working position, that is, in a closed state working position, when the fluid connector joint 1 and the fluid connector plug 2 are not plugged in, thereby preventing the valve core 142 from being turned on due to misoperation.

[0085] When the fluid connector joint 1 and the fluid connector plug 2 are completely plugged in, the fluid connector joint 1 and the fluid connector plug 2 are locked to prevent the valve core 142 from being separated from the preset working position, that is, the conducting state working position, which causes the fluid in the fluid connector to leak due to the separation of the fluid connector joint 1 and the fluid connector plug 2.

[0086] In some embodiments, the valve core 142 or its driving part is coaxially fixed with the 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 portion 134 is in contact with the floating member 17. When the cam portion 134 rotates, it can drive the floating member 17 to slide between the non-first locking position and the first locking position, completing the connection and separation of the joint portion and the fluid connector plug 2. When the valve core 142 is separated from the preset working position, the floating member 17 is separated from the first locking position and abuts against the outer peripheral wall of the non-small diameter end of the cam portion 134. Therefore, the floating member 17 is suppressed by the cam portion 134 and cannot return to the first locking position, that is, it cannot complete the unlocking of the joint portion and the fluid connector plug 2, thereby ensuring the stable locking of the fluid connector joint 1 and the fluid connector plug 2.

[0088] At the same time, after the locking portion locks the floating member 17 in the first locking position, the floating member 17 can lock the cam portion 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 portion 134. When the valve core 142 needs to be disengaged from the preset locking position, the cam portion 134 needs to be rotated. 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 portion 134. At this time, the locking portion locks the floating member 17, so the floating member 17 cannot be disengaged from the first locking position, that is, the cam portion 134 cannot rotate, and then the valve core 142 cannot be disengaged 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 the 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 arranged 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 driving or locking stability 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 and the floating member 17 are perpendicular. 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, thereby preventing the floating member 17 from leaving the first locking position.

[0093] The end pin 15 is slidably connected to the valve body 14, and the sliding direction of the end pin 15 is perpendicular to that of the floating pin 16. The end pin 15 includes an operating part 151 and a track guide part 152. The track guide part 152 is in sliding contact with the floating pin 16. When the operating part 151 is pressed into the valve body 14, the track guide part 152 abuts 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 portion is realized by the combined design of the floating pin 16 and the end pin 15, and the sliding directions of the floating pin 16 and the floating member 17 are perpendicular, which can effectively reduce the movable margin of the floating member 17 when locked in the first locking position, that is, effectively ensure the locking stability of the floating member 17 when it is in the first locking position;

[0095] The sliding direction of the floating pin 16 is perpendicular to the end pin 15, which can effectively reduce the movable margin of the floating pin 16 when locked in the second locking position, that is, effectively ensure 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 pin 15 is consistent with the plugging direction of the fluid connector plug 2, and when the fluid connector plug 2 is docked with the fluid connector connector 1, the fluid connector connector 1 abuts against the driving operating portion 151 to enter the valve body 14; an end pin reset elastic member 153 is provided between the end pin 15 and the valve body 14 to prevent the end pin 15 from entering the valve body 14;

[0097] And / or, the sliding direction of the floating member 17 is consistent with the plugging 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, for preventing the floating member 17 from disengaging from the first locking position;

[0098] And / or, the sliding directions of the floating pin 16 and the floating member 17 are perpendicular, 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 leaving the second locking position.

[0099] like Figure 4 and Figure 5 As shown, the sliding direction of the end pin 15 and the floating member 17 is consistent with the plugging direction of the fluid connector joint 1 and the fluid connector plug 2. When the fluid connector joint 1 and the fluid connector plug 2 are plugged in, the valve core 142 is automatically unlocked from the preset working position, and the fluid connector joint 1 and the fluid connector plug 2 are automatically locked.

[0100] At the same time, a floating member reset elastic member 173 is also provided to ensure that the floating member 17 is always in contact with the cam portion 134 to prevent the floating member 17 from sliding freely;

[0101] A floating pin reset elastic member 162 is also provided to enable the floating pin 16 to automatically return to the second locking position after the external force is eliminated, thereby completing the locking of the floating member 17;

[0102] An end pin reset elastic member 153 is also provided, so that the end pin 15 can automatically extend to the outside of the valve body 14 after the external force is eliminated, and guide the floating pin 16 back to the second locking position to complete the locking of the floating member 17;

[0103] That is, when the fluid connector joint 1 and the fluid connector plug 2 are disengaged, the end pin 15, the floating pin 16 and the floating part 17 can reset themselves to complete the locking of the valve core 142 in the preset working position, thereby preventing the valve core 142 in the fluid connector joint 1 in the non-plugged state from being accidentally turned on.

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

[0105] In certain usage scenarios, even if the fluid connector joint 1 and the fluid connector plug 2 are connected, if the fluid connector is turned on by mistake, it will cause unnecessary consequences. Therefore, a handle lock mechanism is provided on the operating handle 13 to lock the operating handle 13 for the 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 and leave the preset working position. Through double protection, the fluid connector can be prevented from being turned on by mistake.

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

[0107] The locking ball groove 141 is an arc-shaped groove, and the arc center is collinear with the rotation axis of the operating handle 13. A plurality 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 be separated from the operating handle 13 and enter the countersunk hole.

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

[0110] like Figure 3 and Figure 10 As shown, the operating mechanism drives the lock ball 133 to disengage from the operating handle 13 and enter the countersunk hole, thereby realizing the mutual locking of the operating handle 13 and the valve body 14. When the operating mechanism releases the drive of the lock ball 133, the lock ball 133 can disengage from the countersunk hole and combine with the operating handle 13, and can move in the lock 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 slidably mounted on 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 lock pin 132 is provided with a wedge-shaped surface for abutting against the lock ball 133. Only when the lock pin 132 is in the third locking position, the lock pin 132 pushes the lock ball 133 to the third locking position;

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

[0114] like Figure 10 As shown, by the combined use of the vertically sliding operating pin 131 and the locking pin 132, the operating mechanism drives the locking ball 133 to disengage from the operating handle 13, and when the operating pin 131 drives the locking pin 132 to disengage from the third locking position of point C, the drive disappears, and the locking ball 133 can disengage from the countersunk hole and re-combine with the operating handle 13, and can move in 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 lock pin reset elastic member 1321 is provided between the lock pin 132 and the operating handle 13 to prevent the lock pin 132 from being released from the third locking position;

[0116] And / or, an operating pin reset elastic member 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 lock pin reset elastic member 1321 and the operating pin reset elastic member 1311, the lock pin 132 and the operating pin 131 can automatically return to the position of driving the lock ball 133 to disengage from the operating handle 13 when the external force is lost, thereby making the lock ball 133 always maintain the tendency to disengage from the operating handle 13 to enter the countersunk hole.

[0118] At the same time, when processing the slideways of the locking pin 132 and the operating pin 131 in the operating handle 13, through-hole processing is adopted, and a second plug 1322 and a first plug 1312 are respectively provided at the ends of the through-holes for blocking, thereby reducing the processing difficulty of the operating handle 13.

[0119] The present invention also provides a fluid connector, comprising a fluid connector plug 2 and any one of the above-mentioned fluid connector connectors 1. When the fluid connector connector 1 is plugged into the fluid connector plug 2, the fluid connector plug 2 abuts against the driving operating part 151 and slides to the interior of the valve body 14, thereby driving the locking part to disengage from the second locking position.

[0120] When the fluid connector joint 1 is plugged into the fluid connector plug 2, the lock of the valve core 142 in the fluid connector joint 1 can be automatically released, so that it can be released from the preset working position. It is understandable that the fluid connector plug 2 can have the same structure as the fluid connector joint 1.

[0121] Example 2:

[0122] Please refer to Figure 2-Figure 5 , a fluid connector joint, comprising:

[0123] The valve body 14 is provided with a fluid channel 143 and a valve core 142 for controlling the opening and closing of the fluid channel 143. The valve core 142 or its driving portion is coaxially fixed with a cam portion 134. It is understood that the valve core 142 is preferably a ball core, and the ball core is provided 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 channel 143 of the valve body 14. When the ball core moves to the closed position, the ball core blocks the fluid channel 143 to prevent fluid transmission. The valve core 142 or its driving portion refers to the valve core 142 or the driving portion of the valve core 142 of the fluid connector joint 1.

[0124] The floating member 17 is slidably connected to the valve body 14. 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.

[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, thereby limiting the floating member 17 from disengaging from the first locking position.

[0126] like Figure 3 、 Figure 4 and Figure 5 As shown, the valve core 142 or its driving portion is coaxially provided with a cam portion 134, and a floating member 17 is slidably provided in the valve body 14. The sliding direction of the floating member 17 is perpendicular to the rotation axis of the cam portion 134, and the floating member 17 can abut against the outer peripheral wall of the cam portion 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 portion 134. At this time, when the cam portion 134 is driven to rotate, the abutting position of the cam portion 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, and the floating member 17 will be driven to disengage from the first locking position at point A.

[0127] At the same time, a floating pin 16 is also slidably provided in 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 inhibit 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, and then lock the cam portion 134 in the first working position to inhibit the rotation of the cam portion 134. When the floating pin 16 disengages from the second locking position, the lock on the floating member 17 in the first locking position is released. At this time, the floating member 17 releases the restriction on the rotation of the cam portion 134, so that the cam portion 134 disengages from the first working position, that is, drives the valve core 142 to rotate to change the conduction state of the fluid channel 143.

[0128] In the above process, when the cam portion 134 is in the locked state, when the cam portion 134 is driven to operate, the direction of the force applied by the cam portion 134 to the floating member 17 is perpendicular to the actual sliding direction of the floating member 17, thereby effectively reducing the movable margin of the cam portion 134 in the locked state. At the same time, the floating pin 16 is used to further lock the floating member 17 in its own sliding direction, thereby reducing the movable margin of the floating member 17 in its own sliding direction in the locked state. By superimposing the double margin reduction, the movable margin of the valve core 142 in the locked state is further reduced, so that the locked state of the valve core 142 is stabilized, thereby avoiding a decrease in sealing during operation and avoiding 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 and the cam surface of the floating member 17 abut against each other. By changing the abutment position of the cam surface and 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 achieve the locking of the rotation of the cam portion 134, that is, the locking of the rotation of the valve core 142 is achieved.

[0130] In some embodiments, an end pin 15 is further included, the end pin 15 is slidably connected to the valve body 14, and the sliding direction of the end pin 15 is perpendicular to the sliding direction of the floating pin 16;

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

[0132] like Figure 3 、 Figure 4 and Figure 5As shown, the end pin 15 is slidably mounted on the valve body 14, and the sliding direction is perpendicular to the sliding direction of the floating pin 16. A track guide portion 152 is provided in the end pin 15. The track guide portion 152 is in sliding contact with the floating pin 16, thereby converting the movement of the end pin 15 into the movement of the floating pin 16. When the end pin 15 is stationary, the end pin 15 locks the position of the floating pin 16, preventing the floating pin 16 from releasing the lock on the floating member 17, that is, preventing the floating member 17 from locking the cam portion 134.

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

[0134] In some embodiments, the sliding direction of the end face pin 15 is consistent with the plugging direction of the fluid connector joint 1 , and when the fluid connector joint 1 is docked with the fluid connector plug 2 , the fluid connector plug 2 abuts against the driving operating portion 151 and enters the valve body 14 ;

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

[0136] like Figure 1 、 Figure 2 and Figure 3 As shown, the fluid connector joint 1 is used in conjunction with the fluid connector plug 2, and the sliding direction of the end pin 15 is consistent with the plug-in direction of the fluid connector joint 1. When the two are plugged in, the docking end face of the fluid connector plug 2 abuts the driving operating portion 151 to enter the valve body 14, that is, through transmission, the cam portion 134 and the valve core 142 are unlocked; and when the fluid connector plug 2 is disengaged from the fluid connector joint 1, the end pin 15 is automatically reset under the action of the end pin reset elastic member 153, driving the floating pin 16 to slide to the second locking position.

[0137] In some embodiments, there is an angle between the sliding direction of the end pin 15 and the plugging direction of the fluid connector plug 2. For example, the angle is 90°. Then, by providing a guide surface for contacting the fluid connector plug 2 at the free end of the operating portion 151, the movement of the plugging direction of the fluid connector plug 2 is converted into the movement of the end pin 15 along its own sliding direction, which can also achieve the above-mentioned function. However, compared with the sliding direction of the end pin 15 being consistent with the plugging 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 plugging direction of the fluid connector joint 1;

[0139] 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 being disengaged 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 to the valve core 142. In addition, when designing, the sliding direction of the floating member 17 is aligned with the plugging direction of the fluid connector joint 1, which can effectively reduce the radial dimension of the valve body 14 and thus reduce the volume of the fluid connector joint 1.

[0141] At the same time, by adding the floating member reset elastic member 173 , the floating member 17 can always abut against the cam portion 134 , thereby improving the locking stability of the cam portion 134 .

[0142] 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 the cut-off state, 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.

[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 cut-off 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 portion 134, the valve core 142 is in the cut-off state, thereby preventing the valve core 142 from being opened by mistake.

[0145] In some embodiments, when the valve core 142 is in the cut-off position and the fully-conducted position, the position of the floating member 17 is set to 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 position or the fully-conducted position, the two small-diameter ends of the cam portion 134 respectively abut against the floating member 17, thereby realizing the locking of the valve core 142 in the two positions.

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

[0147] The free end of the contact portion 171 is in sliding contact with 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, and a cylindrical abutment portion 171 is vertically arranged in the middle position. The abutment portion 171 is slidably installed with the cylindrical guide hole in the valve body 14. The cylindrical guide hole and the cylindrical abutment portion 171 are easy to process, ensuring a smaller radial movable margin between the two, avoiding the flipping caused by the radial margin between the abutment portion 171 and the cylindrical guide hole when the cam portion 134 drives the floating member 17 to slide, thereby reducing the movable 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 mounted in cooperation with guide holes of corresponding shape in the valve body 14, further suppressing the turning tendency of the floating member 17, reducing the movable margin of the floating member 17 in the locked state, and further reducing the movable margin of the cam portion 134 and the valve core 142;

[0150] like Figure 6 As shown, elastic member fixing holes 175 are provided at both ends of the floating member 17 for installing the floating member reset elastic member 173, and the abutment portion 171 is located in the middle of the floating member 17, so that when the floating member 17 is driven by the cam portion 134, it can balance the force itself to avoid flipping, and ensure that the abutment portion 171 is always in stable abutment with the cam portion 134.

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

[0152] like Figure 4 、 Figure 5 and Figure 6 As shown, a plug pin hole 174 is provided at the side end of the floating member 17 for combining with the plug pin portion 161 of the floating pin 16, that is, when the floating pin 16 is in the second locking position, the plug pin portion 161 can be inserted into the plug pin hole 174 to achieve locking of the floating member 17, which has higher locking stability compared to locking by directly abutting the floating member 17.

[0153] In some embodiments, the sliding direction of the floating pin 16 is perpendicular to the plugging direction of the fluid connector joint 1, 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.

[0154] like Figure 4 and Figure 5As shown, the sliding direction of the floating pin 16 is perpendicular to the plugging direction of the fluid connector joint 1, and its motion trajectory can be an arc trajectory, the arc center of the arc trajectory overlaps with the axis of the fluid connector joint 1, that is, the radial dimension of the valve body 14 is reduced.

[0155] At the same time, a floating pin reset elastic member 162 is added so that the floating pin 16 can automatically slide to the second locking position when the external force is lost, thereby locking the floating member 17 and ensuring the locking stability of the floating member 17.

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

[0157] The plug rod 12 is arranged perpendicular to the docking end surface 11 and is used to be inserted into the fluid connector plug 2 docked with the fluid connector joint 1;

[0158] The plug hole 111 is used to accommodate the plug portion 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 butt end face 11 of the valve body 14 , so as to improve the convenience of plugging and fixing the fluid connector joint 1 and the fluid connector plug 2 .

[0160] The present invention also provides a fluid connector including the above-mentioned fluid connector joint 1, including a fluid connector plug 2 and any one of the above-mentioned fluid connector joints 1. When the fluid connector plug 2 is plugged into the fluid connector joint 1, the fluid connector plug 2 can directly abut and drive or drive the floating pin 16 out of the second locking position through a transmission mechanism.

[0161] like Figure 1 and Figure 2 As shown, the fluid connector joint 1 can be plugged into the fluid connector plug 2, and during the plugging process, the fluid connector plug 2 can abut the driving operating part 151 to enter the valve body 14, that is, drive the end 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, that is, through the plugging of the fluid connector joint 1 and the fluid connector plug 2, the unlocking of the valve core 142 in the fluid connector joint 1 is automatically realized.

[0162] Example 3:

[0163] Please refer to Figure 6-Figure 9 , a fluid connector joint for plugging with the fluid connector plug 2;

[0164] Fluid connector joint 1, comprising:

[0165] The valve body 14 is provided with a fluid channel 143 and a valve core 142 for controlling the flow of the fluid channel 143;

[0166] The floating member 17 has a coupling portion therein for coupling with the plugged 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 is released from the preset working position, the valve core 142 or its driving portion abuts against and drives the floating member 17 to release from the first locking position;

[0168] Only when the floating member 17 is in the first locking position can the coupling portion be disengaged from the plugged fluid connector plug 2 , so as to enable the fluid connector plug 2 to be separated from the fluid connector joint 1 .

[0169] like Figure 7 、 Figure 8 and Figure 9 As shown, when the fluid connector joint 1 and the fluid connector plug 2 are plugged in, after the plugging is completed along their own axes, they are rotated by a preset angle so that the fluid connector joint 1 completes the connection with the fluid connector plug 2. When unlocking, it is necessary to first rotate in the opposite direction to lock the fluid connector joint 1 to the fluid connector plug 2, and then the two are moved away from each other along their own axes to complete the disconnection of the fluid connector.

[0170] like Figure 6 As shown, a plug-in rod locking hole 176 is provided on the surface of the floating member 17. As the floating member 17 slides in the valve body 14, the plug-in 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 plug-in portion of the fluid connector plug 2 overlaps with the axis of the plug rod locking hole 176. When the valve core 142 is out of the preset working position, the valve core 142 or its driving portion abuts against the first locking position of the driving float 17 out of point A. At this time, the plug-in portion of the fluid connector plug 2 and the plug rod locking hole 176 partially overlap in the axial direction, that is, the plug-in portion and the plug rod locking hole 176 will not be able to move radially, that is, the rotation of the fluid connector joint 1 and the fluid connector plug 2 is restricted, that is, the fluid connector joint 1 and the fluid connector plug 2 cannot be unlocked. If the preset working position of the valve core 142 is set The working position is set to the cut-off position of the valve core 142. When the valve core 142 is turned on, the fluid connector joint 1 and the fluid connector plug 2 cannot be unlocked, that is, the fluid connector cannot be disconnected, thereby preventing leakage of the internal fluid. Only when the valve core 142 is cut off, the floating member 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 plug-in portion of the fluid connector plug 2 and the plug rod locking hole 176 have no axial overlap, and the two can move radially, that is, the fluid connector joint 1 and the fluid connector plug 2 can rotate relative to each other, thereby achieving unlocking of the fluid connector joint 1 and the fluid connector plug 2.

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

[0173] In some embodiments, after the floating member 17 is released from the first locking position at point A, it can extend to the outside of the valve body 14 and directly combine with the docked fluid connector plug 2, thereby inhibiting the relative rotation of the fluid connector joint 1 and the fluid connector plug 2, and can also achieve the above-mentioned function. At this time, the sliding direction of the floating member 17 can be the plug-in direction of the fluid connector joint 1 and the fluid connector plug 2, or it can be a direction perpendicular to the plug-in direction of the fluid connector joint 1 and the fluid connector plug 2.

[0174] In some embodiments, the valve core 142 or its driving portion is coaxially fixed with a cam portion 134 , and the cam portion 134 abuts against the floating member 17 ;

[0175] Only when the valve core 142 is in the preset working position, the outer peripheral wall of the small-diameter end of the cam portion 134 can 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 portion 134 abuts against the floating member 17. At this time, the floating member 17 is in the first locking position at point A. At this time, the plug rod locking hole 176 in the floating member 17 and the plug portion of the fluid connector plug 2 do not overlap in the axial direction, that is, there is no locking between the fluid connector joint 1 and the fluid connector plug 2.

[0177] When the valve core 142 is released from the preset working position, the large diameter end of the cam portion 134 abuts against the floating member 17. At this time, the floating member 17 will be released from the first locking position at point A. The plug rod locking hole 176 in the floating member 17 and the plug portion of the fluid connector plug 2 will partially overlap in the axial direction. The two will no longer be able to move relative to each other in their own radial directions. In other words, the fluid connector joint 1 and the fluid connector plug 2 are locked.

[0178] When the fluid connector joint 1 and the fluid connector plug 2 are locked, the floating member 17 will not be able to return to the first locking position due to the abutment of the large diameter end of the cam portion 134, that is, the fluid connector joint 1 and the fluid connector plug 2 cannot be unlocked. When and only when the valve core 142 returns to the preset working position, the floating member 17 can abut against the small diameter end of the cam portion 134, that is, the floating member 17 returns to the first locking position, thereby unlocking the fluid connector joint 1 and the fluid connector plug 2, ensuring the locking stability of the fluid connector joint 1 and the fluid connector plug 2, and effectively preventing the fluid connector joint 1 and the fluid connector plug 2 from being disconnected 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 plug-in direction of the fluid connector joint 1 and the fluid connector plug 2, effectively reducing 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 plug-in direction of the fluid connector joint 1 and the fluid connector plug 2, and is parallel to the rotation axis of the valve core 142. At this time, the cam portion 134 should adopt an end face cam.

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

[0181] The free end of the contact portion 171 is in sliding contact with the outer peripheral wall of the cam portion 134 .

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

[0183] In some embodiments, the fluid connector joint 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 and the floating member 17 are perpendicular. 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, thereby preventing the floating member 17 from leaving the first locking position.

[0184] A floating pin restoring elastic member 162 is provided between the floating pin 16 and the valve body 14 to prevent the floating pin 16 from being released 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 locking the cam portion 134 through the floating member 17 in the first locking position, the valve core 142 working position is locked, and 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 the valve core 142 working position and the fluid connector at the same time, and only when the valve core 142 is in the preset working position, the fluid connector joint 1 and the fluid connector plug 2 can be disengaged, and 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, so that the fluid connector joint 1 has the ability to prevent the valve core 142 from being opened by accident and the valve core 142 from being disengaged from the fluid connector plug 2 by accident when it is opened.

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

[0187] The end face pin 15 includes an operating part 151 and a track guide part 152. The operating part 151 extends to the outside of the valve body 14. The track guide part 152 slides and abuts against the floating pin 16. When the operating part 151 is pressed into the valve body 14, the track guide part 152 abuts 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 joint 1 is used in conjunction with the fluid connector plug 2, and the sliding direction of the end pin 15 is consistent with the plug-in direction of the fluid connector joint 1 and the fluid connector plug 2. When the two are plugged in, the docking end face of the fluid connector plug 2 abuts the driving operating portion 151 to enter the valve body 14, that is, through transmission, the cam portion 134 and the valve core 142 are unlocked; and when the fluid connector plug 2 is disengaged from the fluid connector joint 1, the end pin 15 is automatically reset under the action of the end pin reset elastic member 153, driving the floating pin 16 to slide to the second locking position.

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

[0190] In some embodiments, there is an angle between the sliding direction of the end pin 15 and the plugging direction of the fluid connector plug 2. For example, the angle is 90°. Then, by providing a guide surface for contacting the fluid connector plug 2 at the free end of the operating portion 151, the movement of the plugging direction of the fluid connector plug 2 is converted into the movement of the end pin 15 along its own sliding direction, which can also achieve the above-mentioned function. However, compared with the sliding direction of the end pin 15 being consistent with the plugging 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 portion 151 is provided with a contact surface for abutting against the fluid connector plug 2;

[0192] When the fluid connector plug 2 is plugged into the fluid connector joint 1 , the fluid connector plug 2 drives the operating portion 151 into the interior of the valve body 14 by abutting against the contact surface.

[0193] When the sliding direction of the end face pin 15 is at an angle to the plugging direction of the fluid connector joint 1 and the fluid connector plug 2, such as vertically, a contact surface for guidance is provided at the end of the operating portion 151, so that the movement of the fluid connector joint 1 and the fluid connector plug 2 along the plugging direction is converted into the movement of the end face pin 15 along its own sliding direction, thereby realizing the driving of the floating pin 16 by the end face pin 15, and further realizing the locking or unlocking of the floating part 17.

[0194] In some embodiments, the sliding direction of the end face pin 15 is consistent with the plugging direction of the fluid connector plug 2, and when the fluid connector plug 2 is docked with the fluid connector joint 1, the docking end face of the fluid connector plug 2 abuts against the driving operating portion 151 to enter the valve body 14; an end face pin reset elastic member 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;

[0195] And / or, the sliding direction of the floating member 17 is consistent with the plugging 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 plugging direction of the fluid connector joint 1. When the two are plugged in, the mating end face of the fluid connector plug 2 abuts the driving operating portion 151 to enter the valve body 14, that is, through transmission, the cam portion 134 and the valve core 142 are unlocked; and when the fluid connector plug 2 is disengaged from the fluid connector joint 1, the end face pin 15 is automatically reset under the action of the end face pin reset elastic member 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 member 17 is consistent with the plugging direction of the fluid connector joint 1, which can effectively reduce the radial dimension of the valve body 14 and thus reduce the volume of the fluid connector joint 1;

[0198] At the same time, by adding the floating member reset elastic member 173 , the floating member 17 can always abut against the cam portion 134 , thereby improving the locking stability of the cam portion 134 .

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

[0200] The butt end face 11 of the fluid connector joint 1 is provided with a plug hole 111 for plugging in the plug portion of the fluid connector plug 2;

[0201] The plug-in hole 111 is an arc-shaped long hole, and the arc center of the plug-in hole 111 overlaps with the rotation axis when the fluid connector plug 2 is plugged in. A limiting mechanism is provided at the position where the plug-in hole 111 and the joint part overlap along the plug-in axis direction of the fluid connector plug 2 to prevent the plug-in part from disengaging from the plug-in hole 111.

[0202] like Figure 2 and Figure 3As shown, the mating end face 11 of the fluid connector joint 1 is provided with a plug-in hole 111 for plugging in the plug-in portion of the fluid connector plug 2, and the plug-in hole 111 is provided as an arc-shaped long strip hole, so that after the fluid connector joint 1 and the fluid connector plug 2 are axially plugged in, the plug-in portion can move along the length direction of the plug-in hole 111, that is, the fluid connector joint 1 and the fluid connector plug 2 can rotate around their own axes. When the plug-in portion rotates to the position where the plug-in hole 111 has a limiting mechanism, the fluid connector joint 1 and the fluid connector plug 2 will not be able to move coaxially along the plug-in direction, and the plug-in portion will be disengaged from the plug-in hole 111, that is, the fluid connector joint 1 and the fluid connector plug 2 are locked in the plug-in direction; at this time, the locking of the plug-in portion by the floating member 17 will inhibit the movement of the plug-in portion in the plug-in hole 111, that is, inhibit the fluid connector joint 1 and the fluid connector plug 2 from rotating around the axis, that is, all degrees of freedom of the fluid connector joint 1 and the fluid connector plug 2 are locked.

[0203] In some embodiments, a plug rod 12 is vertically provided on the docking end surface 11 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 portion 122 . The axial cross-sectional area of the head portion 122 is larger than that of the rod portion 121 , so that the head portion 122 is limited 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-in rod 12 is provided on the mating end face 11 as a plug-in portion of the fluid connector joint 1, which is used to be plugged into and / or locked with the plug-in hole in the fluid connector plug 2. Moreover, through the structural design of the rod portion 121 and the head portion 122, after the plug-in rod 12 enters the plug-in hole of the fluid connector plug 2, the fluid connector joint 1 and the fluid connector plug 2 can be relatively rotated to achieve locking of the relative positions of the fluid connector joint 1 and the fluid connector plug 2 along the plug-in direction.

[0206] The present invention also provides a fluid connector including the above-mentioned fluid connector joint, including a fluid connector plug 2 and any one of the above-mentioned 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 is combined with the joint of the fluid connector joint 1.

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

[0208] When the fluid connector joint 1 and the fluid connector plug 2 are plugged in, both have a structure inside to lock them together, and at the same time prevent the valve core 142 in the fluid connector joint 1 or the fluid connector plug 2 from being in a non-preset working position when the two are disengaged.

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

[0210] The fluid connector joint and fluid connector provided by the present invention are described in detail above.

The description of the above embodiments is only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
