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 opening 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 existing system, the locking mechanism usually uses a locking ball to lock the position of the operating handle and the valve body. During the process, countersunk holes for accommodating the locking balls need to be set at the corresponding positions of the operating handle and the valve body. When the locking ball falls into the countersunk hole of the operating handle, the operating handle and the valve body are locked in position. When the locking ball falls into the countersunk hole of the valve body, the operating handle is unlocked.

[0004] In the process of implementing this application, the applicant discovered that the prior art has at least the following problems:

[0005] In order to enable the locking ball to disengage from the countersunk hole when the operating handle and the valve body rotate relative to each other, and at the same time, due to the spherical structure of the locking ball, it is necessary to set a guiding slope or arc surface at the edge of the countersunk hole to reduce the inhibition of the locking ball disengaging from the countersunk hole. Therefore, the actual volume of the countersunk hole is larger than the volume of the locking ball, and the locking ball has a large movable margin in the countersunk hole. That is, when the locking ball enters the countersunk hole of the operating handle, there is still a certain movable margin between the operating handle and the valve body, which makes the shut-off state of the stop valve unstable and there is a problem of fluid leakage.

[0006] In summary, how to solve the problem that the shut-off state of the shut-off valve is unstable when it is locked, resulting in fluid leakage, is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a fluid connector joint, which can reduce the movable margin of the valve core in the locked state. At the same time, the floating pin and the floating part are abutted to limit the floating part in the locked position, further reducing the movable margin of the floating part and the valve core, further ensuring the stability of the valve core in the locked state, and effectively reducing fluid leakage.

[0008] Another object of the present invention is to provide a fluid connector including the above-mentioned fluid connector joint, which has the same technical solution and can improve the same technical problems.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] A fluid connector joint, comprising:

[0011] A valve body, internally provided with a fluid passage and a valve core for controlling the on / off of the fluid passage, and a cam portion coaxially and fixedly provided on the valve core or its driving portion;

[0012] A floating member, slidably connected to the valve body, and only when the floating member is in the first locking position, the floating member abuts against the small-diameter end of the cam portion to limit the rotation of the cam portion;

[0013] A floating pin, slidably connected to the valve body, and the sliding direction of the floating pin is perpendicular to that of the floating member. Only when the floating pin is in the second locking position, the floating pin abuts against the floating member in the first locking position to limit the floating member from disengaging from the first locking position.

[0014] Optionally, it further includes an end face pin, which is slidably connected to the valve body, and the sliding direction of the end face pin is perpendicular to that of the floating pin;

[0015] The end face pin includes an operating portion and a trajectory guiding portion. The operating portion extends to the outside of the valve body, and the trajectory guiding portion slidably abuts against the floating pin. When the operating portion is pressed into the valve body, the trajectory guiding portion abuts against and drives the floating pin to disengage from the second locking position.

[0016] Optionally, the sliding direction of the end face pin is the same as the plugging direction of the fluid connector joint, and when the fluid connector joint is docked with the fluid connector plug, the fluid connector plug abuts against and drives the operating portion into the valve body;

[0017] An end face pin return elastic member is provided between the end face pin and the valve body to inhibit the end face pin from entering the valve body.

[0018] Optionally, the sliding direction of the floating member is the same as the plugging direction of the fluid connector joint;

[0019] A floating member return elastic member is provided between the floating member and the valve body to inhibit the floating member from disengaging from the first locking position.

[0020] Optionally, the valve core is coaxially and fixedly provided with an operating handle, and the cam portion is coaxially and fixedly connected to the operating handle. Only when the valve core is in the closed state, the floating member is in the first locking position and abuts against the outer peripheral wall of the small-diameter end of the cam portion.

[0021] Optionally, the floating member includes an abutting portion which is cylindrical and is slidably mounted coaxially with a cylindrical guiding hole in the valve body;

[0022] The free end of the abutting portion is slidably abutted against the outer peripheral wall of the cam portion.

[0023] Optionally, a plug pin hole is provided at the side end of the floating member. Only when the floating member is in the first locking position, the plug pin portion of the floating pin in the second locking position can be plugged and fixed with the plug pin hole.

[0024] Optionally, the sliding direction of the floating pin is perpendicular to the plugging direction of the fluid connector joint, and a floating pin return elastic member is provided between the floating pin and the valve body to prevent the floating pin from disengaging from the second locking position.

[0025] Optionally, a plug hole and a plug rod are provided on the docking end face of the valve body;

[0026] The plug rod is perpendicular to the docking end face and is used to be inserted into the fluid connector plug that is docked with the fluid connector joint;

[0027] The plug hole is used to accommodate the plugging portion of the fluid connector plug.

[0028] A fluid connector includes a fluid connector plug and the fluid connector joint according to any one of the above. When the fluid connector plug is plugged with the fluid connector joint, the fluid connector plug can directly abut and drive or drive the floating pin to disengage from the second locking position through a transmission mechanism.

[0029] The fluid connector joint provided by the present invention has at least the following beneficial effects compared with the prior art:

[0030] 1. The spool is locked by the way that the cam portion coaxially fixed with the spool or its driving portion abuts against the floating member. Compared with the rolling of the locking ball, the abutting movement between the cam portion and the floating member has a smaller movement margin in the locked state, that is, the spool has a smaller movement margin in the locked state, and the locked state of the spool is more stable, effectively reducing the probability of the fluid connector joint being conducted, thereby effectively reducing fluid leakage.

[0031] 2. The floating member is slidably connected to the valve body, and the floating pin is used to lock the floating member in the locking position. Moreover, the sliding direction of the floating pin is perpendicular to the sliding direction of the floating member, further reducing the movement margin of the floating member in the locking position, making the floating member have a stable positional relationship with the valve body in the locking position, and further reducing the movement margin of the spool it locks, effectively ensuring the locking stability of the conducting state in the fluid connector joint.

[0032] The fluid connector provided by the present invention includes the above-mentioned fluid connector joint and has the same beneficial effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0057] The core of the present invention is to provide a fluid connector joint. By coaxially and fixedly arranging a cam part on the valve core or its driving part, and adopting the method of the cam part abutting and locking with the floating part, the movement allowance of the valve core in the locked state is reduced. At the same time, by adopting the method of the floating pin abutting with the floating part, the floating part in the locking position is limited, further reducing the movement allowance of the floating part and the valve core, further ensuring the stability of the valve core in the locked state, and effectively reducing fluid leakage.

[0058] Another core of the present invention is to provide a fluid connector including the above-mentioned fluid connector joint, which has the same technical solution and can solve the same technical problems.

[0059] Embodiment 1:

[0060] Please refer to Figures 2 - 5 , a fluid connector joint, comprising:

[0061] A valve body 14, with a fluid passage 143 and a valve core 142 for controlling the on / off of the fluid passage 143 arranged inside. A cam portion 134 is coaxially and fixedly arranged on the valve core 142 or its driving portion; it can be understood that the valve core 142 preferably adopts a ball core, and the ball core is provided with a through flow passage hole. When the ball core moves to the open position, the flow passage hole of the ball core is aligned with the fluid passage 143 of the valve body 14, and when the ball core moves to the closed position, the ball core blocks the fluid passage 143 to block 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;

[0062] A floating member 17, 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;

[0063] A floating pin 16, 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 limit the floating member 17 from disengaging from the first locking position.

[0064] As shown in Figure 3 , Figure 4 and Figure 5 , a cam portion 134 is coaxially arranged on the valve core 142 or its driving portion, and a floating member 17 is slidably arranged inside 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 at 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 between 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 at this time, the floating member 17 will be driven to disengage from the first locking position at point A;

[0065] Meanwhile, a floating pin 16 is also slidably arranged inside the valve body 14. When the floating pin 16 is at the second locking position at point B, the floating pin 16 can abut against the floating member 17 at 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 at the second locking position, it can lock the floating member 17 at the first locking position, and further lock the cam portion 134 at 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 locking of the floating member 17 at the first locking position is released. At this time, the floating member 17 releases the restriction on the rotation of the cam portion 134, causing the cam portion 134 to disengage from the first working position, that is, driving the valve core 142 to rotate to change the conduction state of the fluid passage 143.

[0066] In the above process, when the cam portion 134 is in the locked state, when driving the cam portion 134 to act, the acting force direction applied by the cam portion 134 to the floating member 17 is perpendicular to the actual sliding direction of the floating member 17. Therefore, the movement allowance of the cam portion 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 allowance of the floating member 17 in its own sliding direction in the locked state. Through the superposition of the reduction of the two movement allowances, the movement allowance of the valve core 142 in the locked state is further reduced, making the locked state of the valve core 142 stable, avoiding the decrease in sealing performance during operation, and effectively avoiding fluid leakage.

[0067] In some embodiments, the sliding direction of the floating member 17 is parallel to the rotation axis of the cam portion 134. However, the cam portion 134 is an end face cam, and the floating member 17 abuts against the cam surface of the end face cam. By changing the position where the cam surface abuts against the floating member 17, the floating member 17 is driven to slide along its own sliding direction, and then by locking the position of the floating member 17, the rotation of the cam portion 134 is locked, that is, the rotation of the valve core 142 is locked.

[0068] In some embodiments, it further includes an end face pin 15. 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;

[0069] The end face pin 15 includes an operating portion 151 and a trajectory guiding portion 152. The operating portion 151 extends to the outside of the valve body 14, and the trajectory guiding portion 152 slidably abuts against the floating pin 16. When the operating portion 151 is pressed into the valve body 14, the trajectory guiding portion 152 abuts against and drives the floating pin 16 to disengage from the second locking position.

[0070] Such as Figure 3 、 Figure 4 and Figure 5As shown, the end face 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 trajectory guiding portion 152 is provided inside the end face pin 15. By the sliding contact between the trajectory guiding portion 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 locking of the floating member 17, that is, to prevent the floating member 17 from locking the cam portion 134;

[0071] Moreover, the end face pin 15 includes an operating portion 151 extending outside the valve body 14, that is, the user can directly press the operating portion 151 to drive the end face pin 15 to act, and then drive the floating pin 16 to disengage from the second locking position, release the locking of the floating member 17, so that the cam portion 134 can change its contact position with the floating member 17, and then the cam portion 134 can rotate, driving the valve core 142 to act and changing the conduction state of the fluid passage 143.

[0072] In some embodiments, the sliding direction of the end face pin 15 is the same as the insertion direction of the fluid connector joint 1. When the fluid connector joint 1 is docked with the fluid connector plug 2, the fluid connector plug 2 abuts and drives the operating portion 151 into the valve body 14;

[0073] An end face pin return elastic member 153 is provided between the end face pin 15 and the valve body 14 to inhibit the end face pin 15 from entering the valve body 14.

[0074] Such as Figure 1 、 Figure 2 and Figure 3 As shown, the fluid connector joint 1 and the fluid connector plug 2 are used in cooperation, and the sliding direction of the end face pin 15 is the same as the insertion direction of the fluid connector joint 1. When the two are inserted, the docking end face of the fluid connector plug 2 abuts and drives the operating portion 151 into the valve body 14, that is, through transmission, the unlocking of the cam portion 134 and the valve core 142 is realized; when the fluid connector plug 2 is separated from the fluid connector joint 1, the end face pin 15 automatically resets under the action of the end face pin return elastic member 153, driving the floating pin 16 to slide to the second locking position.

[0075] In some embodiments, there is an included angle between the sliding direction of the end face pin 15 and the insertion direction of the fluid connector plug 2. For example, when the included angle is 90°, by providing a guiding surface for contacting the fluid connector plug 2 at the free end of the operating portion 151, the movement in 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 functions can also be realized. However, compared with the case where the sliding direction of the end face pin 15 is the same as the insertion direction of the fluid connector joint 1, the radial dimension of the valve body 14 is increased in this embodiment, resulting in an increase in the overall space occupied by the fluid connector joint 1.

[0076] In some embodiments, the sliding direction of the floating member 17 is consistent with the insertion direction of the fluid connector joint 1;

[0077] A floating member return 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.

[0078] Such as 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 fixedly arranged coaxially with the valve core 142. During design, making the sliding direction of the floating member 17 consistent with the insertion direction of the fluid connector joint 1 can effectively reduce the radial dimension of the valve body 14, and further reduce the volume of the fluid connector joint 1;

[0079] Meanwhile, by adding the floating member return elastic member 173, the floating member 17 can always be in contact with the cam portion 134, improving the locking stability of the cam portion 134.

[0080] In some embodiments, an operating handle 13 is fixedly arranged coaxially with the valve core 142, and the cam portion 134 is fixedly arranged coaxially with the operating handle 13. Only when the valve core 142 is in the closed state, the floating member 17 is in the first locking position and is in contact with the outer peripheral wall of the small-diameter end of the cam portion 134.

[0081] Such as Figure 4 and Figure 5 As shown, combining the cam portion 134 with the operating handle 13, that is, locking the operating handle 13 to achieve locking of the valve core 142;

[0082] Moreover, when the valve core 142 is in the closed state, the position where the floating member 17 is located is set as the first locking position, that is, when the floating member 17 locks the cam portion 134, the valve core 142 is in the closed state, thereby avoiding misoperation and conduction of the valve core 142;

[0083] In some embodiments, when the valve core 142 is in the closed and fully open positions, the positions where the floating member 17 is located are set as 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 closed or fully open position, the two small-diameter end positions of the cam portion 134 are respectively in contact with the floating member 17, that is, locking of the valve core 142 at two positions is achieved.

[0084] In some embodiments, the floating member 17 includes a contact portion 171. The contact portion 171 is cylindrical and is slidably installed coaxially with a cylindrical guiding hole in the valve body 14;

[0085] The free end of the contact portion 171 is in sliding contact with the outer peripheral wall of the cam portion 134.

[0086] Such asFigure 6 As shown, the floating member 17 is an arc-shaped strip structure, and a cylindrical abutting portion 171 is vertically provided at the middle position. The abutting portion 171 is slidably installed in a cylindrical guiding hole in the valve body 14. When the cylindrical guiding hole and the cylindrical abutting portion 171 are processed, the processing difficulty is relatively low, ensuring a small radial movement allowance between the two, and avoiding the flipping caused by the radial allowance between the abutting portion 171 and the cylindrical guiding hole when the cam portion 134 drives the floating member 17 to slide, thereby reducing the movement allowance of the floating member 17 in the locked state.

[0087] As Figure 6 shown, guiding portions 172 are provided at both ends of the floating member 17 and are slidably installed in cooperation with corresponding-shaped guiding holes in the valve body 14, further suppressing the flipping tendency of the floating member 17, reducing the movement allowance of the floating member 17 in the locked state, and further reducing the movement allowances of the cam portion 134 and the valve core 142;

[0088] As Figure 6 shown, elastic member fixing holes 175 are provided at both ends of the floating member 17 for installing the floating member return elastic member 173, and the abutting portion 171 is located in the middle of the floating member 17. When the floating member 17 is driven by the cam portion 134, it can be balanced in force by itself, avoiding flipping, and ensuring that the abutting portion 171 is always in stable contact with the cam portion 134.

[0089] In some embodiments, a plug pin hole 174 is provided at the side end of the floating member 17. Only when the floating member 17 is in the first locked position, the plug pin portion 161 of the floating pin 16 in the second locked position can be inserted and fixed with the plug pin hole 174.

[0090] As Figure 4 、 Figure 5 and Figure 6 shown, a plug pin hole 174 is provided at the side end of the floating member 17 for engaging with the plug pin portion 161 of the floating pin 16. That is, when the floating pin 16 is in the second locked position, the plug pin portion 161 can be inserted into the plug pin hole 174 to lock the floating member 17. Compared with directly abutting and locking the floating member 17, it has higher locking stability.

[0091] In some embodiments, the sliding direction of the floating pin 16 is perpendicular to the insertion direction of the fluid connector joint 1, and a floating pin return 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 locked position.

[0092] As Figure 4 and Figure 5As shown, the sliding direction of the floating pin 16 is perpendicular to the insertion direction of the fluid connector joint 1, and its movement trajectory can be an arc trajectory. The center of the arc 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.

[0093] At the same time, a floating pin return elastic member 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 member 17 and ensure the stability of the locking of the floating member 17.

[0094] In some embodiments, the docking end face 11 of the valve body 14 is provided with a plug hole 111 and a plug rod 12;

[0095] The plug rod 12 is perpendicularly arranged with respect to the docking end face 11 and is used for inserting into the interior of the fluid connector plug 2 that is docked with the fluid connector joint 1;

[0096] The plug hole 111 is used for accommodating the plug portion of the fluid connector plug 2.

[0097] As Figure 2 and Figure 3 shown, by providing the plug hole 111 and the plug rod 12 on the docking end face 11 of the valve body 14, the convenience of inserting and fixing the fluid connector joint 1 and the fluid connector plug 2 is improved.

[0098] The present invention also provides a fluid connector including the above-mentioned fluid connector joint 1, which includes a fluid connector plug 2 and the fluid connector joint 1 of any one of the above. When the fluid connector plug 2 is inserted into the fluid connector joint 1, the fluid connector plug 2 can directly abut and drive or drive the floating pin 16 to disengage from the second locking position through a transmission mechanism.

[0099] As Figure 1 and Figure 2 shown, the fluid connector joint 1 can be inserted into the fluid connector plug 2, and during the insertion process, the fluid connector plug 2 can abut and drive the operation portion 151 to 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 member 17 at the first locking position, that is, realize the unlocking of the cam portion 134 and the valve core 142, that is, through the insertion 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.

[0100] Embodiment 2:

[0101] Please refer to Figures 6 - 9 , a fluid connector joint 1 for inserting into a fluid connector plug 2 to form a fluid connector;

[0102] The fluid connector joint 1 includes:

[0103] Valve body 14, with a fluid passage 143 and a valve core 142 inside for controlling the on-off of the fluid passage 143; it can be understood that the valve core 142 preferably adopts a ball core, and the ball core is provided with a through flow passage hole. When the ball core moves to the open position, the flow passage hole of the ball core is aligned with the fluid passage 143 of the valve body 14, and when the ball core moves to the closed position, the ball core blocks the fluid passage 143 to block fluid transmission;

[0104] Floating member 17, which is provided with a coupling portion inside for coupling with the inserted fluid connector plug 2 to limit the separation of the fluid connector plug 2 from the fluid connector joint 1;

[0105] When the valve core 142 disengages from the preset working position, the valve core 142 or its driving portion abuts against and drives the floating member 17 to disengage from the first locking position; 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;

[0106] Only when the floating member 17 is in the first locking position, the coupling portion can disengage from the inserted fluid connector plug 2, so that the fluid connector plug 2 and the fluid connector joint 1 can be separated.

[0107] Such as Figure 7 、 Figure 8 And Figure 9 As shown, when the fluid connector joint 1 and the fluid connector plug 2 are inserted, after being axially inserted into each other, they are rotated by a preset angle to complete the connection of the fluid connector joint 1 to the fluid connector plug 2. When unlocking, it is necessary to first rotate in the reverse direction to lock the fluid connector joint 1 to the fluid connector plug 2, and then the two move away from each other axially to complete the disconnection of the fluid connector.

[0108] Such as Figure 6 As shown, the surface of the floating member 17 is provided with a plug rod locking hole 176, and as the floating member 17 slides in the valve body 14, the plug rod locking hole 176 can move along its own axis direction;

[0109] Such as Figure 8 And Figure 9As shown, when the fluid connectors are connected, the axis of the insertion part of the fluid connector plug 2 overlaps with the axis of the insertion rod locking hole 176. When the valve core 142 disengages from the preset working position, the valve core 142 or its driving part abuts against and drives the 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 insertion rod locking hole 176 partially overlap axially, that is, the insertion part and the insertion rod locking hole 176 cannot perform radial movement, that is, the rotation of the fluid connector joint 1 and the fluid connector plug 2 is restricted, that is, unlocking of the fluid connector joint 1 and the fluid connector plug 2 cannot be achieved. If the preset working position of the valve core 142 is set as the cut-off position of the valve core 142, when the valve core 142 is conducting, unlocking between the fluid connector joint 1 and the fluid connector plug 2 cannot be achieved, that is, the fluid connector cannot be disconnected, avoiding leakage of internal fluid. Only when the valve core 142 is cut off, the floating part 17 is abutted and driven by the valve core 142 or its driving part to return to the first locking position at point A. At this time, there is no overlapping part axially between the insertion part of the fluid connector plug 2 and the insertion rod locking hole 176, and the two can perform radial movement, that is, the fluid connector joint 1 and the fluid connector plug 2 can rotate relative to each other, realizing unlocking of the fluid connector joint 1 and the fluid connector plug 2;

[0110] It should be noted that the axis of the insertion part of the fluid connector plug 2 and the axis of the insertion rod locking hole 176 should be parallel to and non-overlapping with the rotation axes of the fluid connector joint 1 and the fluid connector plug 2.

[0111] In some embodiments, after the floating part 17 disengages from the first locking position at point A, it can extend outside the valve body 14 and directly combine with the docked fluid connector plug 2, thereby suppressing the relative rotation of the fluid connector joint 1 and the fluid connector plug 2, and the above functions can also be achieved. At this time, the sliding direction of the floating part 17 can be the insertion direction of the fluid connector joint 1 and the fluid connector plug 2, or the direction perpendicular to the insertion direction of the fluid connector joint 1 and the fluid connector plug 2.

[0112] In some embodiments, a cam part 134 is coaxially and fixedly arranged on the valve core 142 or its driving part, and the cam part 134 abuts against the floating part 17;

[0113] Only when the valve core 142 is in the preset working position, the outer peripheral wall of the small-diameter end of the cam part 134 can abut against the floating part 17 in the first locking position.

[0114] Such as 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, there is no axial overlap between the insertion rod locking hole 176 in the floating member 17 and the insertion portion of the fluid connector plug 2, that is, there is no locking between the fluid connector joint 1 and the fluid connector plug 2;

[0115] When the valve core 142 disengages 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 disengage from the first locking position at point A, and the insertion rod locking hole 176 in the floating member 17 and the insertion portion of the fluid connector plug 2 will partially overlap axially, and the two will not be able to generate relative movement along their own radial directions, that is, the fluid connector joint 1 and the fluid connector plug 2 are locked;

[0116] Moreover, when the fluid connector joint 1 and the fluid connector plug 2 are locked, due to the abutment of the large-diameter end of the cam portion 134 on the floating member 17, the floating member 17 will not be able to return to the first locking position, that is, the unlocking of the fluid connector joint 1 and the fluid connector plug 2 cannot be achieved. 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, and the unlocking of the fluid connector joint 1 and the fluid connector plug 2 is realized, ensuring the stability of the locking of the fluid connector joint 1 and the fluid connector plug 2, and effectively avoiding the disconnection of the fluid connector joint 1 and the fluid connector plug 2 when the valve core 142 does not return to the preset working position.

[0117] In some embodiments, the sliding direction of the floating member 17 is the same as the insertion 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 insertion 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.

[0118] In some embodiments, the floating member 17 includes an abutting portion 171. The abutting portion 171 is cylindrical and is slidably installed coaxially with the cylindrical guiding hole in the valve body 14;

[0119] The free end of the abutting portion 171 slidably abuts against the outer peripheral wall of the cam portion 134.

[0120] Such as Figure 6As shown, the floating member 17 is an arc-shaped strip structure, and a cylindrical abutting portion 171 is vertically provided at the middle position. The abutting portion 171 is slidably installed in a cylindrical guiding hole in the valve body 14. When processing the cylindrical guiding hole and the cylindrical abutting portion 171, the processing difficulty is relatively low, ensuring a small radial movement allowance between the two. Thus, when the floating member 17 slides, the axis of the plug locking hole 176 can always overlap with the axis of the plugging portion of the fluid connector plug 2, ensuring smooth insertion of the two and reducing the interference during the axial relative movement between the plugging portion and the floating member 17.

[0121] In some embodiments, the fluid connector joint 1 further includes a floating pin 16. 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 limit the floating member 17 from disengaging from the first locking position.

[0122] A floating pin return elastic member 162 is provided between the floating pin 16 and the valve body 14 to inhibit the floating pin 16 from disengaging from the second locking position.

[0123] As Figure 4 and Figure 5 shown, by adding the locking of the floating member 17 in the first locking position by the floating pin 16, and then locking the cam portion 134 by the floating member 17 in the first locking position, the locking of the working position of the valve core 142 is achieved. The locking of the valve core 142 is linked to 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. 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. When the floating pin 16 is in the second locking position at point B, the locking of the valve core 142 in the preset working position is achieved, enabling the fluid connector joint 1 to have the ability to prevent the valve core 142 from being accidentally opened and from being accidentally disengaged from the fluid connector plug 2 when the valve core 142 is opened.

[0124] In some embodiments, the fluid connector joint 1 further includes an end face pin 15. 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.

[0125] The end face pin 15 includes an operating portion 151 and a trajectory guiding portion 152. The operating portion 151 extends to the outside of the valve body 14, and the trajectory guiding portion 152 slidably abuts against the floating pin 16. When the operating portion 151 is pressed into the valve body 14, the trajectory guiding portion 152 abuts against and drives the floating pin 16 to disengage from the second locking position.

[0126] As Figure 1 、 Figure 2 and Figure 3As shown, the fluid connector joint 1 is used in cooperation with the fluid connector plug 2, and the sliding direction of the end face pin 15 is the same as the insertion direction of the fluid connector joint 1 and the fluid connector plug 2. When the two are inserted, the docking end face of the fluid connector plug 2 abuts against and drives the operating part 151 into the valve body 14, that is, through transmission, the unlocking of the cam part 134 and the valve core 142 is realized; when the fluid connector plug 2 is separated from the fluid connector joint 1, the end face pin 15 automatically resets under the action of the end face pin return elastic part 153, and drives the floating pin 16 to slide to the second locking position.

[0127] That is, when the fluid connector joint 1 and the fluid connector plug 2 are inserted, the preset working position locking of the valve core 142 is automatically released, and when the valve core 142 is separated from the preset working position, the separation of the fluid connector joint 1 and the fluid connector plug 2 is automatically locked.

[0128] In some embodiments, there is an included angle between the sliding direction of the end face pin 15 and the insertion direction of the fluid connector plug 2. For example, when the included angle is 90°, by providing a guiding surface for contacting the fluid connector plug 2 at the free end of the operating part 151, the movement in 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 functions can also be realized. However, compared with the case where the sliding direction of the end face pin 15 is the same as the insertion direction of the fluid connector joint 1, the radial dimension of the valve body 14 is increased in this embodiment, resulting in an increase in the overall space occupied by the fluid connector joint 1.

[0129] In some embodiments, the operating part 151 is provided with a contact surface for abutting against the fluid connector plug 2;

[0130] 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 interior of the valve body 14 by abutting against the contact surface.

[0131] When there is an included angle, such as a perpendicular angle, between the sliding direction of the end face pin 15 and the insertion direction of the fluid connector joint 1 and the fluid connector plug 2, by providing a guiding contact surface at the end of the operating part 151, the movement of the fluid connector joint 1 and the fluid connector plug 2 in the insertion direction is converted into the movement of the end face pin 15 along its own sliding direction, 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.

[0132] In some embodiments, the sliding direction of the end face pin 15 is the same as the insertion 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 and drives the operating part 151 into the valve body 14; a end face pin return elastic part 153 is arranged between the end face pin 15 and the valve body 14, which is used to inhibit the end face pin 15 from entering the valve body 14;

[0133] 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.

[0134] 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;

[0135] 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;

[0136] 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 .

[0137] In some embodiments, the sliding direction of the floating member 17 is consistent with the plugging direction of the fluid connector joint 1;

[0138] 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;

[0139] 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.

[0140] like Figure 2 and Figure 3As shown in the figure, the docking end face 11 of the fluid connector joint 1 is provided with a plugging hole 111 for the plugging portion of the fluid connector plug 2 to be plugged in, and the plugging hole 111 is set as an arc-shaped long hole. After the fluid connector joint 1 and the fluid connector plug 2 are axially plugged in, the plugging portion can move along the length direction of the plugging hole 111, that is, the fluid connector joint 1 and the fluid connector plug 2 can rotate around their own axes. When the plugging portion rotates to the position where the plugging 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 plugging direction to separate the plugging portion from the plugging hole 111, that is, the locking of the fluid connector joint 1 and the fluid connector plug 2 along the plugging direction is realized; at this time, through the locking of the plugging portion by the floating member 17, the movement of the plugging portion in the plugging hole 111 will be inhibited, that is, the rotation of the fluid connector joint 1 and the fluid connector plug 2 around the axis will be inhibited, that is, the locking of all degrees of freedom of the fluid connector joint 1 and the fluid connector plug 2 is realized.

[0141] In some embodiments, a plugging rod 12 is vertically provided on the docking end face 11 for plugging into the plugging hole of the fluid connector plug 2;

[0142] The plugging rod 12 includes a relatively fixed rod portion 121 and a head portion 122, and the axial cross-sectional area of the head portion 122 is larger than the axial cross-sectional area of the rod portion 121, which is used to limit the head portion 122 by the limiting mechanism of the plugging hole of the fluid connector plug 2.

[0143] Such as Figure 2 and Figure 3 As shown in the figure, a plugging rod 12 is provided on the docking end face 11 as the plugging portion of the fluid connector joint 1 for plugging and / or locking with the plugging hole in the fluid connector plug 2, and through the structural design of the rod portion 121 and the head portion 122, after the plugging rod 12 enters the plugging hole of the fluid connector plug 2, the relative rotation of the fluid connector joint 1 and the fluid connector plug 2 can be used to realize the locking of the relative positions of the fluid connector joint 1 and the fluid connector plug 2 along the plugging direction.

[0144] The present invention also provides a fluid connector including the above-mentioned fluid connector joint, which includes a fluid connector plug 2 and the fluid connector joint of any one of the above. When the fluid connector joint 1 is plugged with the fluid connector plug 2 and the valve core 142 of the fluid connector joint 1 is disengaged from the preset working position, the joint portion of the fluid connector plug 2 and the fluid connector joint 1 is combined.

[0145] Among them, the fluid connector plug 2 is preferably the same as the structure of the fluid connector joint 1;

[0146] When the fluid connector joint 1 and the fluid connector plug 2 are plugged together, both of them have a structure inside to lock the two, and at the same time, when the two are separated, the valve core 142 in the fluid connector joint 1 or the fluid connector plug 2 is prevented from being in a non-preset working position.

[0147] Embodiment III:

[0148] Please refer to Figures 2 - 5 , a fluid connector joint for plugging with the fluid connector plug 2;

[0149] The fluid connector joint includes:

[0150] A valve body 14 with a fluid passage 143 and a valve core 142 inside for controlling the on / off of the fluid passage 143; it can be understood that the valve core 142 preferably uses a ball core, and the ball core is provided with a through flow passage hole. When the ball core moves to the open position, the flow passage hole of the ball core is aligned with the fluid passage 143 of the valve body 14, and when the ball core moves to the closed position, the ball core blocks the fluid passage 143 to block fluid transmission;

[0151] A 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 part to lock the movement of the valve core 142 or its driving part; it can be understood that the valve core 142 or its driving part refers to the valve core 142 or the driving part of the valve core 142 of the fluid connector joint 1;

[0152] A 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 limit the floating member 17 from disengaging from the first locking position;

[0153] The operating part 151 of the locking part extends to the outside of the valve body 14. When the fluid connector joint 1 is plugged with the fluid connector plug 2, the fluid connector plug 2 abuts against and drives the operating part 151 to slide into the inside of the valve body 14 to drive the locking part to disengage from the second locking position.

[0154] As Figure 4 and Figure 5 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 to complete the locking of the valve core 142 or its driving part in the preset working position. Since when the floating member 17 is at the first locking position at point A, the locking part locks it, the floating member 17 has no possibility of disengaging from the first locking position, so the valve core 142 has no possibility of mis-conducting;

[0155] Meanwhile, 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 together, the fluid connector plug 2 can directly or indirectly abut against and drive the operating part 151 to act, thereby controlling the locking part to release the locking of the floating part 17 at the first locking position. Even if the valve core 142 or its driving part is in the unlocked state, that is, when the fluid connector joint 1 and the fluid connector plug 2 are completely plugged together, the locking of the valve core 142 at the preset working position is automatically released, and the user can directly operate the on-off of the valve core 142, thereby reducing the complexity of the operation of the fluid connector.

[0156] In some embodiments, the floating part 17 is provided with a coupling part for coupling with the plugged fluid connector plug 2 to restrict the separation of the fluid connector plug 2 from the fluid connector joint 1.

[0157] When the valve core 142 disengages from the preset working position, the valve core 142 or its driving part abuts against and drives the floating part 17 to disengage from the first locking position.

[0158] Only when the floating part 17 is in the first locking position can the coupling part disengage from the plugged fluid connector plug 2, so that the fluid connector plug 2 and the fluid connector joint 1 can be separated.

[0159] Such as Figures 6 - 9 , the floating part 17 is provided with a coupling part. When the floating part 17 disengages from the first locking position at point A, its coupling part can be coupled and locked with the plugged fluid connector plug 2, so that the fluid connector joint 1 and the fluid connector plug 2 are locked and cannot be separated.

[0160] Only when the floating part 17 is in the first locking position can the coupling part disengage from the plugged fluid connector plug 2, and only at this time can the fluid connector joint 1 and the fluid connector plug 2 be unlocked and separated.

[0161] However, in use, when the valve core 142 disengages from the preset working position, the floating part 17 immediately disengages from the first locking position, that is, the fluid connector joint 1 and the fluid connector plug 2 are locked after being plugged.

[0162] And 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 are unlocked and separated after being plugged.

[0163] In actual use, the working position of the valve core 142 in the cut-off state is set as the preset working position. That is, when the valve core 142 is in the conducting state, the fluid connector joint 1 and the fluid connector plug 2 are locked and cannot be separated. 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 separated, effectively avoiding the separation of the fluid connector joint 1 and the fluid connector plug 2 when the fluid connector is in the conducting state.

[0164] That is, the combination of the floating member 17 and the locking portion locks the preset working position of the valve core 142 when the fluid connector joint 1 and the fluid connector plug 2 are not plugged together, that is, locks the working position in the cut-off state, to prevent the valve core 142 from being conducted due to misoperation.

[0165] When the fluid connector joint 1 and the fluid connector plug 2 are plugged together, it locks the fluid connector joint 1 and the fluid connector plug 2 to prevent the valve core 142 from departing from the preset working position, that is, when in the conducting state working position, to prevent fluid leakage in the fluid connector caused by the separation of the fluid connector joint 1 and the fluid connector plug 2.

[0166] In some embodiments, a cam portion 134 is coaxially and fixedly provided on the valve core 142 or its driving portion. 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.

[0167] Such as Figure 3 、 Figure 4 and Figure 5 As shown, by using the cam portion 134 to abut against the floating member 17, when the cam portion 134 rotates, it can drive the floating member 17 to slide, so that it slides between the non-first locking position and the first locking position, to complete the engagement and disengagement of the engaging portion and the fluid connector plug 2. And when the valve core 142 departs from the preset working position, the floating member 17 departs 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 inhibited by the cam portion 134 and cannot return to the first locking position, that is, cannot complete the unlocking of the engaging portion and the fluid connector plug 2, thus ensuring the stable locking of the fluid connector joint 1 and the fluid connector plug 2.

[0168] 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 depart from the preset locking position, the cam portion 134 needs to rotate. At this time, the floating member 17 departs from the first locking position to abut against the outer peripheral wall of other positions of the cam portion 134. And at this time, the locking portion locks the floating member 17, so the floating member 17 cannot depart from the first locking position, that is, the cam portion 134 cannot rotate, and further the valve core 142 cannot depart from the preset working position.

[0169] In some embodiments, an operating handle 13 is coaxially and fixedly provided on the valve core 142, and the cam portion 134 is coaxially and fixedly provided 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.

[0170] As Figure 4 and Figure 5 shown, by disposing the cam portion 134 on the operating handle 13, the machining difficulty of the fluid connector joint 1 is reduced, which helps to improve the machining accuracy of the cam portion 134, and further ensures the driving or locking stability between the cam portion 134 and the floating member 17.

[0171] In some embodiments, the locking portion includes:

[0172] 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 limit the floating member 17 from disengaging from the first locking position;

[0173] 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. The end face pin 15 includes an operating portion 151 and a trajectory guiding portion 152. The trajectory guiding portion 152 is in sliding abutment with the floating pin 16. When the operating portion 151 is pressed into the valve body 14, the trajectory guiding portion 152 abuts against and drives the floating pin 16 to disengage from the second locking position.

[0174] As Figure 4 and Figure 5 shown, through the combined design of the floating pin 16 and the end face pin 15, the function of the locking portion is realized, and the sliding directions of the floating pin 16 and the floating member 17 are perpendicular, which can effectively reduce the movement margin of the floating member 17 during locking in the first locking position, that is, effectively ensure the locking stability of the floating member 17 in the first locking position;

[0175] And the sliding directions of the floating pin 16 and the end face pin 15 are perpendicular, which can effectively reduce the movement margin of the floating pin 16 during locking in the second locking position, that is, effectively ensure the locking stability of the floating pin 16 in the second locking position.

[0176] In some embodiments, the sliding direction of the end face pin 15 is the same as the insertion direction of the fluid connector plug 2, and when the fluid connector plug 2 is docked with the fluid connector joint 1, the fluid connector joint 1 abuts against and drives the operating portion 151 into the valve body 14; an end face pin return elastic member 153 is disposed between the end face pin 15 and the valve body 14 to inhibit the end face pin 15 from entering the valve body 14;

[0177] And / or, the sliding direction of the floating member 17 is the same as the insertion direction of the fluid connector plug 2; a floating member return elastic member 173 is disposed between the floating member 17 and the valve body 14 to inhibit the floating member 17 from disengaging from the first locking position;

[0178] And / or, the floating pin 16 is perpendicular to the sliding direction of the floating member 17. A floating pin return 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.

[0179] As Figure 4 and Figure 5 shown, the sliding directions of the end face pin 15 and the floating member 17 are the same as the insertion 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 inserted, the unlocking of the preset working position of the valve core 142 is automatically completed, and the fluid connector joint 1 and the fluid connector plug 2 are automatically locked;

[0180] Meanwhile, a floating member return elastic member 173 is also provided to ensure that the floating member 17 is always in contact with the cam portion 134, preventing the floating member 17 from sliding freely;

[0181] A floating pin return elastic member 162 is also provided, so that after the external force acting on the floating pin 16 is removed, the floating pin 16 can automatically return to the second locking position to lock the floating member 17;

[0182] An end face pin return elastic member 153 is also provided, so that after the external force acting on the end face pin 15 is removed, the end face pin 15 can automatically extend outside the valve body 14 and guide the floating pin 16 back to the second locking position to lock the floating member 17;

[0183] That is, when the fluid connector joint 1 and the fluid connector plug 2 are separated, the end face pin 15, the floating pin 16 and the floating member 17 can automatically reset to lock the preset working position of the valve core 142, preventing the valve core 142 in the fluid connector joint 1 in the non-inserted state from being accidentally operated to conduct.

[0184] In some embodiments, an operating handle 13 is coaxially and fixedly arranged on the valve core 142, and a handle locking mechanism is arranged inside the operating handle 13 to lock the movement of the operating handle 13.

[0185] In certain usage scenarios, even if the fluid connector joint 1 and the fluid connector plug 2 are inserted and the fluid connector is accidentally operated to conduct, unnecessary consequences will occur. Therefore, by arranging a handle locking mechanism on the operating handle 13 to perform secondary locking on the operating handle 13, the operating handle 13 can drive the valve core 142 to move away from the preset working position only when the floating member 17 and the handle locking mechanism are both unlocked. Through double protection, the fluid connector is prevented from being accidentally operated to conduct.

[0186] In some embodiments, the handle locking mechanism includes a lock ball groove 141, a lock ball 133 and an operating mechanism;

[0187] The lock 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. A number of groups of counterbores are arranged in the lock ball groove 141;

[0188] The locking ball 133 is slidably connected to the operating handle 13. When the operating handle 13 rotates, the locking ball 133 can move within the locking ball groove 141. When the locking ball 133 slides to the position of the counterbore, the locking ball 133 can disengage from the operating handle 13 to enter the counterbore;

[0189] The operating mechanism is used to drive the locking ball 133 to disengage from the operating handle 13.

[0190] As Figure 3 and Figure 10 shown, by driving the locking ball 133 to disengage from the operating handle 13 through the operating mechanism to enter the counterbore, the mutual locking between the operating handle 13 and the valve body 14 is realized. When the driving of the locking ball 133 by the operating mechanism is released, the locking ball 133 can disengage from the counterbore 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 to drive the valve core 142 to act.

[0191] In some embodiments, the operating mechanism includes an operating pin 131 and a locking pin 132 that are slidably installed on the operating handle 13. The moving directions of the locking ball 133, the locking pin 132, and the operating pin 131 are perpendicular to each other in pairs;

[0192] The end of the locking pin 132 is provided with a wedge surface for abutting against the locking ball 133. Only when the locking pin 132 is in the third locking position, the locking pin 132 pushes the locking ball 133 to be in the third locking position;

[0193] The operating pin 131 includes a pressing portion and a guiding portion. The pressing portion extends to the outside of the operating handle 13, and the guiding portion is slidably installed 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.

[0194] As Figure 10 shown, by the combined use of the vertically sliding operating pin 131 and the locking pin 132, the driving of the operating mechanism for the locking ball 133 to disengage from the operating handle 13 is realized. And when the operating pin 131 drives the locking pin 132 to disengage from the third locking position at point C, this driving disappears, and the locking ball 133 can disengage from the counterbore and re-engage with the operating handle 13, and can move within the locking ball groove 141, that is, the locking between the operating handle 13 and the valve body 14 is released.

[0195] In some embodiments, a locking pin return elastic member 1321 is provided between the locking pin 132 and the operating handle 13 to inhibit the locking pin 132 from disengaging from the third locking position;

[0196] And / or, an operating pin return elastic member 1311 is provided between the operating pin 131 and the operating handle 13 to drive the operating pin 131 to return after being pressed.

[0197] As Figure 10As shown, by providing a lock pin return elastic member 1321 and an operating pin return elastic member 1311, the lock pin 132 and the operating pin 131 can automatically return to the position where the driving lock ball 133 disengages from the operating handle 13 when the external force is removed, so that the lock ball 133 always maintains the tendency to disengage from the operating handle 13 and enter the counterbore.

[0198] Meanwhile, when machining the sliding channels of the lock pin 132 and the operating pin 131 in the operating handle 13, through holes are machined, and second plugs 1322 and first plugs 1312 are respectively provided at the ends of the through holes for plugging, thereby reducing the machining difficulty of the operating handle 13.

[0199] The present invention also provides a fluid connector, including a fluid connector plug 2 and the 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 abuts against and drives the operating portion 151 to slide into the interior of the valve body 14, for driving the locking portion to disengage from the second locking position.

[0200] When the fluid connector joint 1 is plugged into the fluid connector plug 2, the locking of the valve core 142 in the fluid connector joint 1 can be automatically released, so that it can disengage from the preset working position.
