Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0068] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0069] See also Figure 1 The fluid connector provided in the embodiment of the present invention includes a first connector 101 and a second connector 102. The first connector 101 and the second connector 102 can be plugged in and matched with each other, so as to realize the connection between two fluid pipelines.

[0070] Reference Figure 2 and Figure 4In order to ensure that the first connector 101 is firmly connected to the second connector 102, the fluid connector further comprises a locking assembly 200, which is used to keep the first connector 101 firmly connected to the second connector 102. Specifically, the locking assembly 200 comprises a locking tongue 210 and a first elastic member 220, wherein the locking tongue 210 is laterally slidably disposed on the first connector 101 so as to be switchable between a first position and a second position, and the first elastic member 220 is connected to the first connector 101 and the locking tongue 210, so as to keep the locking tongue 210 in the first position, and the locking tongue 210 can be operated to switch from the first position to the second position. Among them, when the lock tongue 210 is located in the first position under the action of the first elastic member 220, the lock tongue 210 is in a laterally extended state. At this time, the lock tongue 210 can be engaged with the first insertion rod portion 116 or the second insertion rod portion 114 of the second joint 102 to limit the axial separation of the first joint 101 and the second joint 102; when the lock tongue 210 is located in the second position, the lock tongue 210 is in a laterally contracted state, and the lock tongue 210 releases the axial restriction between the first joint 101 and the second joint 102.

[0071] In specific applications, when the first connector 101 and the second connector 102 of the above-mentioned connector are plugged in and connected, the locking tongue 210 is maintained in the first position under the action of the first elastic member 220, or in other words, the locking tongue 210 is maintained in a laterally extended state under the action of the first elastic member 220 to engage with the second connector 102, thereby axially restricting the first connector 101 and the second connector 102, thereby effectively ensuring that the first connector 101 and the second connector 102 are firmly plugged in and connected, so as to avoid leakage between the first connector 101 and the second connector 102.

[0072] When the first connector 101 and the second connector 102 of the connector need to be axially separated, the staff can easily push the locking tongue 210 to overcome the elastic force of the first elastic member 220 to slide from the first position to the second position, that is, the locking tongue 210 is switched from the first position to the second position by operating the locking tongue 210, or the locking tongue 210 is switched from the lateral extension state to the lateral contraction state. At this time, the locking tongue 210 releases the axial restriction between the first connector 101 and the second connector 102, and the staff can easily pull the first connector 101 and the second connector 102 apart. Of course, if the staff releases the push on the locking tongue 210, the locking tongue 210 is restored from the second position to the first position under the action of the first elastic member 220, or the locking tongue 210 is switched from the lateral contraction state to the lateral extension state, thereby, the locking tongue 210 can be used again to axially restrict the first connector 101 and the second connector 102. As can be seen from the above, the fluid connector provided by the present invention is more convenient to operate when separation is required.

[0073] In order to facilitate the driving of the locking tongue 210 to switch from the first position to the second position, in some embodiments, refer to Figures 3 to 6 The locking assembly 200 further includes a first operating handle 230, which is movably connected to the first joint 101 and is in transmission connection with the lock tongue 210. Specifically, the first operating handle 230 and the lock tongue 210 can be directly in transmission connection, or a transmission structure can be used to achieve transmission connection between the two. The first operating handle 230 can be operated to drive the lock tongue 210 to switch from the first position to the second position (refer to Figure 3 and Figure 4 , or refer to Figure 5 and Figure 6 Of course, the lock tongue 210 may also be provided with an operating portion, and the staff may directly operate the lock tongue 210 to slide horizontally through the operating portion, so that the lock tongue 210 can slide from the first position to the second position.

[0074] It is understandable that the first joint 101 is provided with the first operating handle 230, and when it is necessary to pull the first joint 101 and the second joint 102 apart, the staff can conveniently operate the first operating handle 230 to drive the locking tongue 210 to slide from the first position to the second position, that is, the locking tongue 210 switches from the lateral extension state to the lateral contraction state. At this time, the locking tongue 210 releases the axial restriction between the first joint 101 and the second joint 102, and the staff can conveniently pull the first joint 101 and the second joint 102 apart.

[0075] In some possible embodiments, the first operating handle 230 is slidably connected or rotationally connected to the first joint 101. With this arrangement, the staff can conveniently operate the first operating handle 230 to move, thereby driving the locking tongue 210 to slide from the first position to the second position to achieve axial unlocking between the first joint 101 and the second joint 102.

[0076] In a specific embodiment, referring to Figures 3 to 6 , the side of the first joint 101 is provided with a mounting groove (not shown in the figure) along its longitudinal direction, and the first operating handle 230 is slidably arranged on the inner side of the first joint 101 along the longitudinal direction of the first joint 101 through the mounting groove, and at least partially exposed to the outer side of the first joint 101 for operation by the staff; at the same time, one of the first operating handle 230 and the lock tongue 210 is provided with a guide surface 233, and the other is provided with a push portion 213. The first elastic member 220 acts on the lock tongue 210 laterally toward the inner side of the first joint 101, so that the push portion 213 and the guide surface 233 are kept in a fitting state. Among them, when the first operating handle 230 is pressed to move along the longitudinal direction of the first joint 101, the first operating handle 230 uses the force between the guide surface 233 and the push portion 213 to push the lock tongue 210 to switch from the first position to the second position, thereby realizing the axial unlocking between the first joint 101 and the second joint 102.

[0077] Specifically, the first operating handle 230 is provided with two extension arms 231 arranged in parallel and spaced apart from each other (see Figure 7 ), two extension arms 231 are extended along the longitudinal direction of the first connector 101, and a guide gap 232 is formed between the two, and the lock tongue 210 is transversely and slidably arranged in the guide gap 232 between the two extension arms 231. At the same time, one end of the lock tongue 210 is set as a plug-in portion 211, and the plug-in portion 211 is used to engage with the first plug-in rod portion 116 or the second plug-in rod portion 114 of the second connector 102. The side of the lock tongue 210 is spaced apart with a limiting portion 214 and the above-mentioned pushing portion 213, and the limiting portion 214 is located between the pushing portion 213 and the plug-in portion 211. Among them, the extension arm 231 is located between the limiting portion 214 and the pushing portion 213, so that the lock tongue 210 slides transversely within a set range between the limiting portion 214 and the pushing portion 213, and the side of the extension arm 231 close to the pushing portion 213 forms the above-mentioned guide surface 233. Furthermore, the locking tongue 210 is provided with a receiving groove 212 along its length direction, and the first elastic member 220 may be a spring and is provided in the receiving groove 212 along the length direction of the receiving groove 212. One end of the first elastic member 220 abuts against one end of the receiving groove 212 near the plug-in portion 211. The first connector 101 has a guide protrusion 1113 embedded in the receiving groove 212, and the other end of the first elastic member 220 abuts against the guide protrusion 1113, thereby the first elastic member 220 abuts between the first connector 101 and the locking tongue 210, providing elastic force for the locking tongue 210 to extend and maintain the extended state (refer to Figure 4 and Figure 8 ). As can be seen from the above, the locking assembly 200 adopts the above-mentioned structural form, the locking assembly 200 has a compact structure, and the locking assembly 200 can be compactly assembled on the inner side of the first joint 101 .

[0078] In specific applications, the staff presses the first operating handle 230 to slide along the longitudinal direction of the first joint 101, and the first operating handle 230 uses the guide inclined surface 2333 of the guide surface 233 to act laterally outward on the pushing portion 213 of the lock tongue 210. As a result, the first elastic member 220 is compressed, and the lock tongue 210 slides laterally outward under the action of the first operating handle 230, thereby releasing the axial restriction between the first joint 101 and the second joint 102, and then the first joint 101 and the second joint 102 can be easily pulled apart.

[0079] Further, refer to Figures 5 to 7, along the longitudinal direction of the first joint 101, the guide surface 233 includes a first longitudinal surface 2331, a guide inclined surface 2333 and a second longitudinal surface 2332 connected in sequence, wherein the first longitudinal surface 2331 is extended along the longitudinal direction of the first joint 101, the second longitudinal surface 2332 is extended along the longitudinal direction of the first joint 101, and the first longitudinal surface 2331 is lower than the second longitudinal surface 2332, and the guide inclined surface 2333 is obliquely connected between the first longitudinal surface 2331 and the second longitudinal surface 2332; wherein, when the pushing portion 213 is attached to the first longitudinal surface 2331, the locking tongue 210 is engaged with the first insertion rod portion 116 of the second joint 102 (refer to Figure 5 ), to achieve axial locking between the first connector 101 and the second connector 102; when the push portion 213 is attached to the second longitudinal surface 2332, the locking tongue 210 releases the axial restriction between the first connector 101 and the second connector 102 (refer to Figure 6 ) so that the first connector 101 and the second connector 102 can be pulled apart.

[0080] Specifically, when the first connector 101 and the second connector 102 are plugged into each other, the locking tongue 210 is extended in the lateral direction of the first connector 101 under the action of the first elastic member 220, thereby being engaged with the second connector 102; when the first connector 101 and the second connector 102 need to be pulled out, the staff pushes the first operating handle 230 to slide in the longitudinal direction of the first connector 101, and the pushing portion 213 slides from the first longitudinal surface 2331 along the guiding inclined surface 2333 to the second longitudinal surface 2332, and the first operating handle 230 pushes the locking tongue 210 to slide outward laterally through the guiding inclined surface 2333, thereby releasing the axial restriction of the locking tongue 210 between the first connector 101 and the second connector 102, and then the first connector 101 and the second connector 102 can be pulled out.

[0081] Furthermore, the guide surface 233 also includes a first limiting surface 2334 and a second limiting surface 2335, wherein the first limiting surface 2334 is connected to one end of the first longitudinal surface 2331 away from the guide inclined surface 2333, and is extended along the lateral direction of the first joint 101; the second limiting surface 2335 is connected to one end of the second longitudinal surface 2332 away from the guide inclined surface 2333, and is extended along the lateral direction of the first joint 101. Thus, the first limiting surface 2334 and the second limiting surface 2335 are used to limit the pushing portion 213 from sliding away from the two ends of the guide surface 233, thereby ensuring that the pushing portion 213 slides between the first longitudinal surface 2331, the guiding inclined surface 2333 and the second longitudinal surface 2332, thereby ensuring that the first operating handle 230 can stably push the locking tongue 210 to switch between the first position and the second position; at the same time, the pushing portion 213 includes a first positioning surface 2131, a second positioning surface 2132, a third positioning surface 2133 and a fourth positioning surface 2134 connected in sequence, wherein, when the locking tongue 210 is in the first position, the first positioning surface 2131 is fitted with the first limiting surface 2334, the second positioning surface 2132 is fitted with the first longitudinal surface 2331, and the third positioning surface 2133 is fitted with the guiding inclined surface 2333 (refer to Figure 5 ); When the locking tongue 210 is in the second position, the second positioning surface 2132 is fitted with the second longitudinal surface 2332, and the fourth positioning surface 2134 is fitted with the second limiting surface 2335 (refer to Figure 6 ), with such arrangement, the first operating handle 230 can stably maintain the locking tongue 210 at the first position and the second position, and the third positioning surface 2133 and the guiding inclined surface 2333 are arranged in close contact with each other, which can effectively ensure that the pushing portion 213 can slide smoothly from the first longitudinal surface 2331 to the second longitudinal surface 2332.

[0082] It should be noted that a first longitudinal surface 2331 and a first limiting surface 2334 are provided on the first operating handle 230. Under the action of the first elastic member 220, the first longitudinal surface 2331 and the first limiting surface 2334 can effectively maintain the position of the locking tongue 210, thereby maintaining the axial restriction between the first connector 101 and the second connector 102; and, under the action of the first elastic member 220, the second longitudinal surface 2332 and the second limiting surface 2335 can effectively maintain the position of the locking tongue 210, thereby making the locking tongue 210 unlock the first connector 101 and the second connector 102, thereby facilitating the plugging and unplugging of the first connector 101 and the second connector 102.

[0083] In order to allow the first operating handle 230 to be reset after being pressed, in some embodiments, refer to Figures 5 to 8The fluid connector further includes a second elastic member 240, which may be a spring. One end of the second elastic member 240 abuts against the first connector 101, and the other end abuts against the first operating handle 230. Thus, when the first operating handle 230 is released from being pressed, the second elastic member 240 is used to reset the first operating handle 230 to its initial position. When the second elastic member 240 pushes the first operating handle 230 to reset to its initial position, the first operating handle 230 gradually releases the restriction on the locking tongue 210. Thus, the locking tongue 210 gradually slides laterally under the action of the first elastic member 220, i.e., slides toward the first position, so that it can be used again for axial locking between the first connector 101 and the second connector 102.

[0084] Furthermore, the first operating handle 230 is provided with a waist-shaped hole 234 along the longitudinal direction of the first connector 101. The fluid connector further includes a positioning pin 250, which is slidably disposed on the first connector 101 along the longitudinal direction of the first connector 101, and one end of the positioning pin 250 extends from an end of the first connector 101 close to the second connector 102 (refer to Figure 2 ). At the same time, the positioning pin 250 is located on one side of the first operating handle 230, and a positioning shaft 251 is provided on the side of the positioning pin 250, and the positioning shaft 251 is passed through the waist-shaped hole 234. The second elastic member 240 is connected to the first joint 101 and the inner end of the positioning pin 250, and is used to provide a reset force for the positioning pin 250 toward the second joint 102; when the first joint 101 is separated from the second joint 102, the second elastic member 240 pushes the first operating handle 230 to reset to the initial position in the direction of the second joint 102 through the positioning shaft 251 of the positioning pin 250.

[0085] Specifically, in the first stage, when the first joint 101 and the second joint 102 are in an unconnected state, one end of the positioning pin 250 extends from the butt end of the first joint 101 close to the second joint 102, the positioning shaft 251 is located at one end of the waist-shaped hole 234 close to the second joint 102, the pushing portion 213 is located at the position of the first longitudinal surface 2331 and the first limiting surface 2334, and the locking tongue 210 is in a lateral extending state under the action of the first elastic member 220 (refer to Figure 5 In the second stage, the first joint 101 is plugged into the second joint 102, and the positioning pin 250 is retracted toward the inner side of the first joint 101 under the action of the second joint 102. Accordingly, the positioning shaft 251 slides along the waist-shaped hole to the end of the waist-shaped hole away from the second joint 102 (refer to Figure 3), the locking tongue 210 is engaged with the second connector 102, thereby ensuring that the first connector 101 and the second connector 102 are firmly plugged and connected. In the third stage, when the staff pushes the first operating handle 230 to slide away from the second connector 102 in the longitudinal direction, the positioning shaft 251 is again located at the end of the waist-shaped hole close to the second connector 102 (refer to Figure 6 At the same time, the first operating handle 230 uses the guide slope 2333 to push the lock tongue 210 outward to slide outward, and the lock tongue 210 releases the restriction between the first joint 101 and the second joint 102. In the fourth stage, if the staff releases the pressing force on the first operating handle 230, and the positioning shaft 251 is located at the end of the waist-shaped hole close to the second joint 102 (refer to Figure 4 and Figure 6 ), therefore, when the first connector 101 and the second connector 102 are separated, the second elastic member 240 pushes the positioning pin 250 to slide axially toward the second connector 102, and the positioning pin 250 uses the positioning shaft 251 to push the first operating handle 230 to slide toward the second connector 102 to reset, and the locking tongue 210 is reset to the first position under the action of the first elastic member 220, so that it can be used to lock the second connector 102 again.

[0086] It is understandable that after the staff releases the pressure on the first operating handle 230, since the first joint 101 and the second joint 102 are not separated, the positioning pin 250 is always in a contracted state under the action of the second joint 102, and accordingly, the second elastic member 240 cannot act on the first operating handle 230, so that the first operating handle 230 cannot be reset, and therefore, the lock tongue 210 can be kept in an unlocked state for the second joint 102, so that it is convenient for the staff to pull the first joint 101 and the second joint 102 apart. It can be seen that the staff does not need to keep the first operating handle 230 in a pressed state to keep the lock tongue 210 in an unlocked state, which is more convenient to use.

[0087] In some embodiments, reference Figure 1 The structures of the first connector 101 and the second connector 102 are substantially the same. Therefore, the present application uniformly describes the specific structures of the first connector 101 and the second connector 102, and does not describe the first connector 101 and the second connector 102 separately.

[0088] Specifically, refer to Fig. 9 and Fig.10The first joint 101 and the second joint 102 are collectively referred to as joints, and the joints include a valve seat 110 and a spherical valve core 120, wherein the valve seat 110 is substantially cylindrical, one end of the valve seat 110 is set as a docking end face 115, the valve seat 110 is provided with a fluid channel 113 along its longitudinal direction, the fluid channel 113 forms a docking port on the docking end face 115, and the locking assembly 200 is arranged on the valve seat 110 of the first joint 101. The spherical valve core 120 is substantially spherical, and the spherical valve core 120 is provided with a rotating shaft portion 122 on the opposite side thereof, the spherical valve core 120 is arranged in the fluid channel 113, the rotating shaft portion 122 penetrates the side wall of the valve body 111 of the valve seat 110, and at least partially extends to the outside of the valve body 111 of the valve seat 110, and the spherical valve core 120 is rotatably connected with the valve body 111 of the valve seat 110 through the rotating shaft portion 122. The shaft portion 122 at least partially extends to the outside of the valve seat 110, and the outer end of the shaft portion 122 is configured to be driven so that the spherical valve core 120 rotates in the fluid channel 113. During the rotation of the spherical valve core 120, the fluid channel 113 is closed and opened.

[0089] The rotating shaft portion 122 is connected to the spherical valve core 120 by snapping, or the two are connected in an integrated manner, or are connected in other ways.

[0090] In specific applications, when the first connector 101 and the second connector 102 are plugged and connected, the butt end faces 115 of the two valve seats 110 fit together, and the butt ports of the two fluid channels 113 are connected. In addition, by driving the outer end of the rotating shaft portion 122, the two spherical valve cores 120 respectively switch the circulation channel 113 from a closed state to an open state. If it is necessary to separate the first connector 101 and the second connector 102, by driving the outer end of the rotating shaft portion 122, the two spherical valve cores 120 respectively switch the circulation channel 113 from an open state to a closed state, thereby facilitating the subsequent separation of the first connector 101 and the second connector 102.

[0091] In some embodiments, the spherical valve core 120 is provided with a fluid through hole 121, and the fluid through hole 121 passes through both sides of the spherical valve core 120. When the spherical valve core 120 is in an open state with respect to the fluid channel 113, the two ends of the fluid through hole 121 are respectively facing the two ends of the fluid channel 113, that is, the two ends of the fluid through hole 121 are connected with the fluid channel 230, so that the fluid channel 113 is in an open state. When the spherical valve core 120 is in a closed state with respect to the fluid channel 113, the two ends of the fluid channel 113 are respectively facing the channel wall of the fluid channel 113, so that the fluid channel 113 is in a closed state. In other embodiments, the side wall of the spherical valve core 120 is provided with a notch, which can also replace the above-mentioned fluid through hole 121.

[0092] In order to realize the switching of the valve core between the open position and the closed position, in a possible embodiment, referring to Figures 9 to 12 , the first joint 101 and the second joint 102 both further include a second operating handle 130, which is located outside the valve seat 110, and one end of which is connected to the outer end of the shaft portion 122, and the second operating handle 130 can be operated to drive the shaft portion 122 to rotate. It can be understood that the second operating handle 130 is provided at the outer end of the shaft portion 122, and when in use, the staff can conveniently hold the second operating handle 130, thereby driving the spherical valve core 120 to rotate through the shaft portion 122, so as to realize the switching of the valve core between the open position and the closed position, thereby opening or closing the fluid channel 113.

[0093] Furthermore, the joint further includes a positioning assembly 140, and the side of the valve seat 110 is provided with a first positioning groove 1111 and a second positioning groove 1112 for the positioning assembly 140 to be embedded. If the spherical valve core 120 is in an open state with respect to the fluid channel 113, the ball 146 of the positioning assembly 140 is embedded and matched with the first positioning groove 1111, and the first positioning groove 1111 locks the position of the second operating handle 130, so that the spherical valve core 120 can keep the fluid channel 113 in an open state; if the spherical valve core 120 is in a closed state with respect to the fluid channel 113, the ball 146 of the positioning assembly 140 is embedded and matched with the second positioning groove 1112, and the positioning assembly 140 locks the position of the second operating handle 130, so that the spherical valve core 120 can keep the fluid channel 113 in a closed state.

[0094] Specifically, the positioning assembly 140 includes a push rod 141, an operating push rod 142, a ball 146, a first spring 144 and a second spring 145, wherein the push rod 141 is slidably disposed on the inner side of the second operating handle 130 along the length direction of the second operating handle 130, and a positioning inclined surface 1411 is disposed at the end of the push rod 141. A mounting hole 131 is disposed on one side of the second operating handle 130 close to the valve seat 110, and the ball 146 is mounted in the mounting hole 131 and is disposed in close contact with the positioning inclined surface 1411, and the ball 146 is used to be embedded in the first positioning groove 1111 or the second positioning groove 1112. The operating push rod 142 is slidably disposed inside the second operating handle 130, and the pressing end of the operating push rod 142 is exposed on the side of the second operating handle 130. One of the operating push rod 142 and the push rod 141 is provided with a first transmission inclined surface 1421 to fit with the other. When used, the pressing end of the operating push rod 142 is pressed inward to drive the push rod to move away from the ball 146. In addition, the first elastic member 220 is connected to the valve seat 110 and the push rod 141, and the first elastic member 220 is used to keep the push rod 141 and the operating push rod 142 in contact; and the second spring 145 is connected to the valve seat 110 and the operating push rod 142. After the staff releases the pressure on the operating push rod 142, the pressing end of the operating push rod 142 pops out under the action of the second spring 145.

[0095] Furthermore, the positioning assembly 140 also includes a pushing member 143, which is connected to the inner end of the operating push rod 142. One of the operating push rod 142 and the push rod 141 is provided with a second transmission inclined surface 1431 to fit with the other. After the operating push rod 142 stops being subjected to the pressing force, the pushing member 143 is reset under the action of the second spring 145. During the resetting process, the operating push rod 142 can use the second transmission inclined surface 1431 to act on the push rod 141, thereby causing the push rod 141 to move toward the direction of the ball 146.

[0096] In specific applications, when the position of the spherical valve core 120 needs to be rotated, the staff member, while holding the second operating handle 130, presses the pressing end of the operating push rod 142 to retract into the second operating handle 130, and the operating push rod 142 acts on the push rod 141 using the first transmission inclined surface 1421, and the push rod 141 slides away from the ball 146, and the positioning inclined surface 1411 at the end of the push rod 141 releases the restriction on the ball 146. Therefore, when the staff member rotates the second operating handle 130, the ball 146 can retract to the inside of the mounting hole 131, thereby separating from the first positioning groove 1111 or the second positioning groove 1112, and then the second operating handle 130 can be operated to rotate. When the staff member stops pressing the operating push rod 142, the push rod 141 slides toward the direction of the ball 146 again under the action of the first spring 144, and uses the positioning inclined surface 1411 to push out the ball 146, so that the ball 146 can be embedded in the first positioning groove 1111 or the second positioning groove 1112 again, thereby maintaining the position of the second operating handle 130. At the same time, the second spring 145 is used to drive the pressing end of the operating push rod 142 to pop out again for the staff member to press next time; and during the resetting process of the operating push rod 142, the operating push rod 142 also uses the second transmission inclined surface 1431 to act on the push rod 141, so that the positioning inclined surface 1411 of the push rod 141 can maintain the force on the ball 146, so that the ball 146 can stably embed in the first positioning groove 1111 or the second positioning groove 1112, thereby maintaining the position of the second operating handle 130.

[0097] In order to switch the valve core between the open state and the closed state, in a possible embodiment, referring to Figure 1 , Fig.13 and Fig.14, the butt end surface 115 is provided with a guide groove 1151 and a raised first plug-in rod portion 116, the end of the first plug-in rod portion 116 is provided with a first limiting convex edge 1161, and the guide groove 1151 is circumferentially extended with the butt end port as the center; at the same time, the joint also includes: a first transmission member 150 and a second transmission member 160, the first transmission member 150 is generally arranged in a block shape, the first transmission member 150 is located at a position corresponding to the guide groove 1151, and is linearly slidably arranged on the inner side of the guide groove 1151, and the sliding direction is perpendicular to the longitudinal direction of the valve seat 110. The first transmission member 150 is provided with a slot 152 on one side close to the guide groove 1151, and the length direction of the slot 152 is perpendicular to the sliding direction of the first transmission member 150. Among them, when the two joints are connected in cooperation, the first plug-in rod portion 116 is plug-connected with the slot 152, and can slide relative to the first transmission member 150 along the length direction of the slot 152. The second transmission member 160 is in transmission connection with the rotating shaft portion 122 and the first transmission member 150 . When the first transmission member 150 slides, it drives the rotating shaft portion 122 to rotate through the second transmission member 160 . Among them, when the two valve seats 110 rotate relative to each other in the forward direction, the first plug rod portion 116 moves circumferentially along the guide groove 1151, and the first limiting protrusion 1161 of the first plug rod portion 116 is clamped on the inner side of the valve cover 112 of the valve seat 110, and the locking tongue 210 can be clamped with the first limiting protrusion 1161 of the first plug rod portion 116; at the same time, when the two valve seats 110 rotate relative to each other in the forward direction, the first transmission member 150 and the second transmission member 160 drive the shaft portion 122 to rotate forwardly to drive the spherical valve core 120 to rotate from the closed position to the open position; and when the two valve seats 110 rotate relative to each other in the reverse direction, the first plug rod portion 116 moves circumferentially along the guide groove 1151, and the first transmission member 150 and the second transmission member 160 drive the shaft portion 122 to rotate reversely to drive the spherical valve core 120 to rotate from the open position to the closed position.

[0098] Specifically, when the two joints are connected, or when the two joints are in a connected state, the first rod portion 116 is inserted into the slot 152 of the first transmission member 150 through the guide groove 1151. When the two joints rotate relative to each other in the forward or reverse direction, the first rod portion 116 pushes the first transmission member 150 to slide linearly. The length direction of the slot 152 is perpendicular to the sliding direction of the first transmission member 150. When the first rod portion 116 pushes the first transmission member 150 to slide, the first rod portion 116 slides along the length direction of the slot 152. Therefore, when the first rod portion 116 moves in a circular arc along the guide groove 1151, it can also push the first transmission member 150 to slide, and there is no interference between the two. Because the first transmission member 150 is connected to the shaft portion 122 through the second transmission member 160, the first transmission member 150 acts on the shaft portion 122 through the second transmission member 160 during the sliding process, thereby driving the spherical valve core 120 to rotate, thereby realizing the closing and opening of the fluid channel 113.

[0099] In a specific embodiment, a first tooth portion 151 is provided on one side of the first transmission member 150 close to the shaft portion 122, and a plurality of first tooth portions 151 are sequentially provided along the sliding direction of the first transmission member 150; meanwhile, the second transmission member 160 is roughly wheel-shaped, and the second transmission member 160 is sequentially provided with second tooth portions 161 in its circumferential direction, and the first tooth portions 151 mesh with the second tooth portions 161. Specifically, the first transmission member 150 is equivalent to a rack, and the second transmission member 160 is equivalent to a gear. When the first insertion rod portion 116 pushes the first transmission member 150 to slide linearly, the first transmission member 150 drives the second transmission member 160 to rotate, and the second transmission member 160 drives the spherical valve core 120 to rotate synchronously through the shaft portion 122, thereby realizing the opening or closing of the fluid channel 113.

[0100] Instead of the above-mentioned structure of the first transmission member 150 and the second transmission member 160, in another possible embodiment, the second transmission member 160 is a rod-shaped body, one end of the second transmission member 160 is rotatably connected to the first transmission member 150, and the other end is provided with a sliding hole, and the length direction of the sliding hole is arranged in the same direction as the length direction of the second transmission member 160 (not shown in the figure). A positioning plane is arranged on the side of the rotating shaft portion 122, and the rotating shaft portion 122 is penetrated in the sliding hole, and the positioning plane of the rotating shaft portion 122 is arranged to fit the inner wall of the sliding hole, thereby, the rotating shaft portion 122 and the second transmission member 160 are arranged to slide and are circumferentially restricted.

[0101] Specifically, when the first insertion rod portion 116 pushes the first transmission member 150 to slide linearly, the second transmission member 160 rotates relative to the first transmission member 150, and the shaft portion 122 slides relative to the second transmission member 160 along the length direction of the sliding hole, thereby the second transmission member 160 drives the shaft portion 122 to rotate. When the shaft portion 122 rotates, it drives the spherical valve core 120 to rotate synchronously, thereby realizing the opening and closing of the fluid channel 113.

[0102] In some embodiments, reference Figure 1 , Fig.13 and Fig.14 The docking end face 115 is provided with a raised second plug rod portion 114, and the second plug rod portion 114 is provided with one or more, and the end of the second plug-in portion 211 is provided with a second limiting convex edge 1141; at the same time, the docking end face 115 is also provided with a connecting card slot 1152, and the connecting card slot 1152 is circumferentially extended with the docking port as the center, and the connecting card slot 1152 and the second plug rod portion 114 are provided in equal numbers. In the circumferential direction around the docking port, the connecting card slot 1152 and the second plug rod portion 114 are alternately arranged in sequence. Among them, the guide groove 1151 and the first plug rod portion 116 are located at the periphery of the connecting card slot 1152, more precisely, the guide groove 1151 and the first plug rod portion 116 are located at the edge area of ​​the docking end face 115, but are not limited to being only provided at the edge area of ​​the docking end face 115.

[0103] In specific applications, when the two joints are connected, the second rod portions 114 of the two valve seats 110 extend into the connection slots 1152 of each other, and the locking tongue 210 can be clamped with the second limiting convex edge 1141 of the second rod portion 114. When the two joints rotate relative to each other in the positive direction, the second rod portion 114 is clamped in the connection slot 1152 by rotation, so that the second limiting convex edge 1141 of the second rod portion 114 is clamped on the inner side of the valve cover 112 of the valve seat 110, thereby achieving axial clamping of the two valve seats 110, thereby achieving connection of the two joints. When the two joints rotate relative to each other in the reverse direction, the second rod portion 114 is released from the clamping with the connection slot 1152 by rotation, so that the two valve seats 110 are released from axial clamping, thereby achieving the separation of the two joints.

[0104] As can be seen from the above, when the two joints rotate relative to each other in the positive direction, the second rod portion 114 moves in the positive circumferential direction along the connecting slot 1152, thereby realizing the connection of the two joints; and the first rod portion 116 moves in the positive circumferential direction along the guide slot 1151, thereby driving the spherical valve core 120 to rotate through the first transmission member 150 and the second transmission member 160, thereby realizing the opening of the fluid channel 113. When the two joints rotate relative to each other in the reverse direction, the second rod portion 114 moves in the reverse circumferential direction along the connecting slot 1152, thereby releasing the restriction between the second rod portion 114 and the connecting slot 1152; and the first rod portion 116 moves in the reverse circumferential direction along the guide slot 1151, thereby driving the spherical valve core 120 to rotate in the other direction through the first transmission member 150 and the second transmission member 160, thereby realizing the closing of the fluid channel 113.
