Description

Technical Field

[0001] The present invention relates to the technical field of liquid cooling systems, and particularly relates to a connection end, a fluid connector, and a liquid cooling system. Background Art

[0002] A fluid connector generally includes two connection ends, and the two connection ends can be docked with each other to achieve the connection of pipelines. The existing connection end includes a valve seat, a valve core, and a valve cover. The valve cover is fixedly connected to the valve seat, and a chamber for the valve core to rotate is formed between the valve cover and the valve seat. The opening and closing of the flow channel inside the connection end are realized by the rotation of the valve core.

[0003] In the process of implementing the present invention, the inventor found that there are at least the following problems in the prior art: The connection end needs to reserve a moving space for the valve plate, resulting in a relatively long axial length of the connection end, which is not conducive to the application in small-space scenarios. Summary of the Invention

[0004] An object of the present invention is to provide a connection end that can effectively solve the problem of the relatively large axial dimension of the connection end. Another object is to provide a fluid connector including the above-mentioned connection end. Still another object is to provide a liquid cooling system including the above-mentioned fluid connector.

[0005] To achieve the above objects, the present invention provides the following technical solutions:

[0006] A connection end includes: a first valve body and a first valve cover. The first valve body is provided with a first flow channel. The first valve cover includes a first outer shell and a first valve disposed in the first outer shell. The first outer shell is rotatably sleeved on the outer periphery of the first valve body. The first valve is located at one end of the first valve body. The first valve is provided with a first channel. When the first outer shell rotates circumferentially to a first position, the first channel is completely staggered from the first flow channel to close the first flow channel. When the first outer shell rotates circumferentially to a second position, the first channel communicates with the first flow channel to open the first flow channel.

[0007] In some technical solutions, the first valve is integrally formed with the first outer shell, and the first valve and the first outer shell form a barrel-shaped structure covering the first valve body.

[0008] In some technical solutions, the first valve body is provided with a first stop portion that can axially extend and retract. The first valve is provided with a first locking groove. When the first outer shell is in the first position, the first stop portion extends out and is clamped in the first locking groove to limit the rotation of the first outer shell relative to the first valve body.

[0009] In some technical solutions, a first pushing portion extending axially is provided on the first valve body, a first arc-shaped groove and a second arc-shaped groove are provided on the first valve along the circumferential direction, the first pushing portion axially passes out of the first arc-shaped groove, and the first locking groove is located at one end within the second arc-shaped groove.

[0010] In some technical solutions, the connection end further includes a first connection cap. The first valve is located at one end of the first outer shell, and the first connection cap is connected to the end of the first outer shell away from the first valve. The first connection cap is used to axially limit the first valve cover on the first valve body.

[0011] In some technical solutions, the first valve body includes a first section and a second section distributed axially. The outer diameter of the first section is greater than that of the second section, and a step surface is formed between the first section and the second section. At least part of the structure of the first outer shell is sleeved on the outer periphery of the first section, the first connection cap is sleeved on the outer periphery of the second section, the outer periphery of the first connection cap is detachably connected within the first outer shell, and one end of the first connection cap abuts against the step surface.

[0012] In some technical solutions, at least two first flow channels are provided on the first valve body, the first valve is provided with first channels having the same number as the first flow channels. When the first outer shell rotates circumferentially to the first position, each of the first channels is completely staggered from each of the first flow channels; when the first outer shell rotates circumferentially to the second position, each of the first channels is in one-to-one correspondence and communication with each of the first flow channels.

[0013] A fluid connector includes a docking end and also includes the connection end described in any one of the above. The docking end is detachably connected to the connection end.

[0014] In some technical solutions, the docking end includes a second valve body and a second valve cover. A second flow channel is provided within the second valve body. The second valve cover includes a second outer shell and a second valve provided within the second outer shell. The second valve is provided with a second channel. The second outer shell is rotatably sleeved on the outer periphery of the second valve body, and the first valve cover and the second valve cover are detachably connected.

[0015] In some technical solutions, the docking end further includes a second connection cap. The second valve is located within the second outer shell, and the second connection cap is connected to the end of the second outer shell away from the second valve. The second connection cap is used to axially limit the second valve cover on the second valve body.

[0016] In some technical solutions, one end of the second housing is sleeved on the outer periphery of the first housing. A mating projection protruding radially is provided on the outer periphery of the first housing, and a mating slot is provided on the side wall of the second housing. The mating projection and the mating slot can be inserted into each other so that the first housing and the second housing can rotate synchronously to connect or close the first flow channel and the second flow channel.

[0017] In some technical solutions, a receiving groove is provided on the circumferential surface of the first valve body. A lock hole and a lock bead movably connected to the lock hole are provided on the first housing. The lock hole has a first opening facing the first valve body and a second opening facing away from the first valve body. The lock bead can partially be located in the receiving groove along the first opening. When the first housing rotates relative to the first valve body to open the first flow channel, the lock hole can drive the lock bead out of the receiving groove and contact the circumferential surface of the first valve body, so that part of the lock bead extends out along the second opening. A connecting groove extending in the circumferential direction is formed in the inner wall of one end of the second housing sleeved on the first housing. The connecting groove is used to receive part of the lock bead extending out of the second opening to define the axial positions of the first housing and the second housing. When the first housing rotates in the opposite direction relative to the first valve body to close the first flow channel, the lock hole can drive the lock bead to move along the circumferential surface of the first valve body until part of the structure of the lock bead retracts into the receiving groove, so that the first housing and the second housing can be separated from each other in the axial direction.

[0018] In some technical solutions, a plurality of the lock holes distributed in the circumferential direction and a plurality of the lock beads corresponding to the lock holes one by one are provided on the first housing.

[0019] In some technical solutions, a locking member that can expand and contract radially is provided on the second valve body. A locking hole is provided on the second housing. When the locking member is snapped into the locking hole, the first flow channel and the second flow channel are connected. When the locking member retracts into the second valve body, the second housing can rotate relative to the second valve body.

[0020] In some technical solutions, a pressing portion is provided on the second housing. The pressing portion is used to push the locking member to retract when a pressure is applied.

[0021] In some technical solutions, a rubber sleeve is sleeved on the outer periphery of the second housing. The pressing portion is provided on the rubber sleeve and is used to reset under the elastic force of the rubber sleeve when the pressure is removed.

[0022] In some technical solutions, a first pipeline joint is detachably connected to one end of the first valve body away from the first valve. The first pipeline joint is communicated with the first flow channel. A second pipeline joint is detachably connected to one end of the second valve body away from the second valve. The second pipeline joint is communicated with the second flow channel.

[0023] A liquid cooling system includes the fluid connector according to any one of the above.

[0024] Compared with the prior art, the above technical solutions have at least the following advantages:

[0025] For a connection end provided by the present invention, since the first housing is sleeved on the outer periphery of the valve body and can be directly rotated by the user to open and close the first valve, compared with the prior art where a rotatable valve core needs to be provided between the valve cover and the valve body to open and close the flow channel, the valve core is omitted, which can effectively reduce the length of the connection end in the axial direction, and there is no need to provide an operation part outside the valve cover and a linkage mechanism passing through, which can effectively reduce the complexity of the connection end.

[0026] A fluid connector provided by the present invention also has corresponding advantages because it includes the above connection end.

[0027] A liquid cooling system provided by the present invention also has corresponding advantages because it includes the above fluid connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] 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 creative efforts shall fall within the protection scope of the present invention.

[0054] Please refer to Figures 1 to 12 .

[0055] A connection end 100 provided by an embodiment of the present invention can be used in cooperation with a docking end 200, where the docking end 200 can be the same as or partially different from the connection end 100 in structure. For example, Figures 1 to 3As shown, the connecting end 100 includes: a first valve body 110 and a first valve cover 120, the first valve body 110 is provided with a first flow channel 111, the first valve cover 120 includes a first shell 121 and a first valve 122 fixedly arranged on the first shell 121, the first valve 122 can be integrally formed on the first shell 121, the first valve 122 and the first shell 121 form a barrel-shaped structure covered on the first valve body 110, when assembling, the first valve cover 120 can be directly covered on the first valve body 110, so the assembly is more convenient, the first valve 122 can be provided with a first channel 1221, the number of the first channel 1221 The number of the first flow channels 111 is the same as that of the first flow channels 111. For example, when the first valve body 110 is provided with one first flow channel 111, the first valve 122 is also provided with one first channel 1221; when the first valve body 110 is provided with two first flow channels 111, the first valve 122 is also provided with two first channels 1221 accordingly; when the first valve body 110 is provided with more first flow channels 111, the first valve 122 is also provided with more first channels 1221 accordingly, wherein the first flow channel 111 should be eccentrically arranged relative to the axis of the first valve body 110, and the first channel 1221 should also be eccentrically arranged relative to the axis of the first valve 122. Among them, the first shell 121 can be rotatably sleeved on the outer periphery of the first valve body 110, and the outer peripheral surface of the first shell 121 is exposed to the outside, so that the user can directly rotate the first shell 121. The first valve 122 is located at one end of the first valve body 110. The function of the first valve 122 is mainly to open and close the first flow channel 111. The position of the first valve 122 in the circumferential direction can be achieved by rotating the first shell 121. When the first shell 121 is located at a first position along the circumferential direction, for example, when the first channel 1221 is completely offset relative to the first flow channel 111, the first valve 122 closes the first flow channel 111. When the first shell 121 is located at a second position along the circumferential direction, for example, when the plane projection of the first channel 1221 relative to the first flow channel 111 in the axial direction at least partially overlaps, the first valve 122 opens the first flow channel 111. Since the first shell 121 is sleeved on the outer circumference of the valve body, the user can directly rotate it to realize the opening and closing of the first valve 122. Compared with the prior art that requires a rotatable valve core to be arranged between the valve cover and the valve body to open and close the flow channel, the valve core is omitted, and the axial length of the connecting end 100 can be effectively reduced. In addition, there is no need to arrange an operating part outside the valve cover and a linkage mechanism passing through the valve cover, which can effectively reduce the complexity of the structure of the connecting end 100, thereby reducing costs and improving the convenience of maintenance.

[0056] In some embodiments, in order to ensure that the first valve 122 can stably close the first flow channel 111 on the first valve body 110 before the connection end 100 is connected to the docking end 200, so as to effectively prevent the liquid in the first flow channel 111 from leaking, a first stop portion 115 that can axially expand and contract is provided on the first valve body 110, and a first locking groove 1224 is provided on the first valve 122. The first stop portion 115 can be a spring pin. For example, a concave cavity can be provided at one end of the first valve body 110 facing the first valve 122, and the spring pin is arranged in the concave cavity. The first locking groove 1224 can be a through hole provided on the first valve 122. When the first outer shell 121 is in the first position, the first stop portion 115 extends out and is clamped in the first locking groove 1224 to limit the rotation of the first outer shell 121 relative to the first valve body 110. For example, the head of the spring pin is clamped in the through hole; when it is necessary to unlock the locking relationship between the first valve 122 and the first valve body 110 in the circumferential direction, the first stop portion 115 can be pushed by the structure on the docking end 200 to push the first stop portion 115 back into the first valve body 110. At this time, the first outer shell 121 can rotate relative to the axis of the first valve body 110, thereby realizing the opening of the first flow channel 111.

[0057] In some embodiments, a first pushing portion 114 extending axially is provided on the first valve body 110, and a first arc-shaped groove 1222 and a second arc-shaped groove 1223 distributed in the circumferential direction are provided on the first valve 122. The arc lengths of the first arc-shaped groove 1222 and the second arc-shaped groove 1223 in the circumferential direction are the same. The first pushing portion 114 axially passes through the first arc-shaped groove 1222. When the first valve cover 120 rotates relative to the first valve body 110, the first arc-shaped groove 1222 can play a role in avoiding the first pushing portion 114. One end of the first locking groove 1224 is located in the second arc-shaped groove 1223, that is, when the first valve cover 120 is in the first position, the first stop portion 115 is clamped in the first locking groove 1224. When the docking end 200 is axially docked with the connection end 100, the pushing portion on the docking end 200 will insert into the first locking groove 1224 to push the first stop portion 115 to retract into the first valve body 110. At the same time, the pushing portion on the docking end 200 will further insert into the first valve body 110 to realize the connection of the two valve bodies of the docking end 200 and the connection end 100. At this time, the positions of the two valve bodies in the circumferential direction can be restricted, and then the first outer shell 121 can be rotated to achieve the purpose of the first valve 122 opening the first flow channel 111.

[0058] In some embodiments, in order to define the axial position of the first valve cover 120 relative to the first valve body 110, the connecting end 100 further includes a first connecting cap 130. The first valve 122 is located at one end of the first housing 121. The first connecting cap 130 is connected to the end of the first housing 121 away from the first valve 122. The first connecting cap 130 is used to axially limit the first valve cover 120 on the first valve body 110 to prevent the problem of axial movement of the first valve cover 120. For example, after the first valve cover 120 is sleeved on the first valve body 110, the first connecting cap 130 is connected. The first connecting cap 130 and the first valve 122 can clamp the first valve body 110 axially. After the first housing 121 is connected to the first connecting cap 130, the two can rotate synchronously relative to the first valve body 110.

[0059] In some embodiments, the first valve body 110 includes a first section 1101 and a second section 1102 distributed axially. The outer diameter of the first section 1101 is greater than the outer diameter of the second section 1102. The first valve 122 is located at the end of the first section 1101 away from the second section 1102. A step surface 1103 is formed between the first section 1101 and the second section 1102. At least part of the structure of the first housing 121 is sleeved on the outer periphery of the first section 1101. For example, a part of the structure of the first housing 121 is sleeved on the outer periphery of the first section 1101, and the other part is located on the outer periphery of the second section 1102. At this time, an annular cavity is formed between the first housing 121 and the second section 1102. The first connecting cap 130 is sleeved on the outer periphery of the second section 1102, that is, the first connecting cap 130 is an annular structure. The outer periphery of the first connecting cap 130 is detachably connected to the inside of the first housing 121, and one end of the first connecting cap 130 abuts against the step surface 1103. The first connecting cap 130 can be connected to the first housing 121 by means of threaded connection or snap connection. For example, external threads can be provided on the outer periphery of the first connecting cap 130, and internal threads matching the external threads are provided at the position corresponding to the second section 1102 inside the first housing 121. Further, a flange can be provided on the outer periphery of the end of the first connecting cap 130 away from the first valve 122. When the first connecting cap 130 is connected to the first housing 121, by contacting the flange with the end of the first housing 121 away from the first valve 122, the length of the first connecting cap 130 screwed into the first housing 121 can be defined.

[0060] An embodiment of the present invention also provides a fluid connector, such as Figures 7 to 12As shown, it includes a docking end 200 and also includes any of the above-mentioned connecting ends 100, and the docking end 200 is detachably connected to the connecting end 100. The docking end 200 may include the same structure as the connecting end 100, or may be a different structure. For example, for a docking end 200 with a different structure, the docking end 200 includes a valve body, a valve cover and a valve core, the valve cover is fixedly connected to the valve body, the valve core is located in an active cavity between the valve cover and the valve core, the first pushing portion 114 on the connecting end 100 may pass through the valve cover on the docking end 200 to connect with the valve core, and the movement of the valve core in the docking end 200 can be achieved by rotating the first housing 121.

[0061] In some embodiments, the docking end 200 may include the same structure as the connecting end 100, for example Figures 4 to 7 As shown, the docking end 200 includes a second valve body 210 and a second valve cover 220, a second flow channel 211 is provided in the second valve body 210, the second valve cover 220 includes a second shell 221 and a second valve 222 provided in the second shell 221, a second channel 2214 can be provided on the second valve 222, when the second channel 2214 is connected with the second flow channel 211, the docking end 200 is opened; when the second channel 2214 and the second flow channel 211 are completely offset from each other, the docking end 200 is closed. The second housing 221 is rotatably sleeved on the outer periphery of the second valve body 210, wherein the docking end 200 has the same structure as the connecting end 100, at least including that the second housing 221 can rotate relative to the second valve body 210, and no valve core is required. In addition, the second valve body 210 on the docking end 200 is provided with a second pushing portion 213 and an axially retractable second stop portion 215, and the second valve 222 is provided with a first movable groove and a second movable groove distributed along the circumferential direction, the first movable groove and the second movable groove are arc grooves, wherein the second pushing portion 213 can extend from the first movable groove, and the second valve 222 can rotate circumferentially relative to the second valve body 210 under the action of the first movable groove, the second stop portion 215 can be clamped in the second locking groove 1224 set at one end of the second movable groove, the first pushing portion 114 can push the second stop portion 215 to retract into the second valve body 210, and the second pushing portion 213 can push the first stop portion 115 to retract into the second valve body 210. The first valve cover 120 and the second valve cover 220 are detachably connected. For example, when the docking end 200 and the connecting end 100 need to be connected, the first valve cover 120 and the second valve cover 220 can be connected so that the first valve cover 120 and the second valve cover 220 can rotate synchronously, thereby realizing the opening or closing of the first flow channel 111 and the second flow channel 211.

[0062] In some embodiments, the docking end 220 further includes a second connection cap 250. The second valve 222 is located within the second housing 221. The second connection cap 250 is connected to one end of the second housing 221 away from the second valve 222. The second connection cap 250 is used to axially limit the second valve cover 220 on the second valve body 210. During assembly, as Figure 5 shown, the second housing 221 can be first sleeved on the second valve body 210 from right to left, and then the second connection cap 250 can be connected to the left end of the second housing 221 from left to right so that the second connection cap 250 abuts against the second valve body 210. A stepped surface can be provided on the outer periphery of the second valve body 210, an external thread is provided on the outer periphery of the second connection cap 250, and an internal thread is provided on the inner side of one end of the second housing 221 away from the second valve 222. The second connection cap 250 can be sleeved on the outer periphery of the second valve body 210. By threadedly connecting the second connection cap to the second housing 221, the second connection cap 250 can be tightened against the stepped surface, thereby realizing the axial positioning of the second housing 221.

[0063] In some embodiments, one end of the second housing 221 is sleeved on the outer periphery of the first housing 121 to ensure the centering of the first housing 121 and the second housing 221. An insertion projection 1212 protruding radially is provided on the outer periphery of the first housing 121, and an insertion slot 2212 is provided on the side wall of the second housing 221. When the docking end 200 and the connection end 100 are axially connected, the insertion projection 1212 and the insertion slot 2212 can be inserted into each other so that the first housing 121 and the second housing 221 can rotate synchronously to connect or close the first flow channel 111 and the second flow channel 211. After the first housing 121 and the second housing 221 are inserted, the first housing 121 or the second housing 221 can be operated to rotate, and thus the first valve 122 and the second valve 222 can be rotated synchronously. Therefore, the operation is relatively convenient.

[0064] In some embodiments, in order to improve the stability of the docking end 200 and the connection end 100 after docking, a receiving groove 112 is provided on the circumferential surface of the first valve body 110, a locking hole 1211 is provided on the first outer shell 121, and a locking bead 113 movably connected to the locking hole 1211. The locking hole 1211 has a first opening facing the first valve body 110 and a second opening facing away from the first valve body 110. The aperture of the first opening is larger than that of the second opening, and the aperture of the second opening is smaller than the diameter of the locking bead 113. When the connection end 100 and the docking end 200 are not inserted, the locking bead 113 can partially be located in the receiving groove 112 along the first opening. When the first outer shell 121 rotates relative to the first valve body 110 to open the first flow channel 111, the locking hole 1211 can drive the locking bead 113 out of the receiving groove 112 and contact the circumferential surface of the first valve body 110, so that a part of the locking bead 113 extends out along the second opening. A connecting groove 2213 extending in the circumferential direction is formed in the inner wall of one end of the second outer shell 221 sleeved on the first outer shell 121. The cross-section of the connecting groove 2213 can be trapezoidal or arc-shaped. After the second outer shell 221 is sleeved on the first outer shell 121, when the first outer shell 121 and the second outer shell 221 are rotated, a part of the structure of the locking bead 113 extends out of the second opening of the locking hole 1211. At this time, the connecting groove 2213 can accommodate a part of the locking bead 113 extending out of the second opening to limit the axial positions of the first outer shell 121 and the second outer shell 221. Since the locking bead 113 has the characteristic of being able to roll, during the clamping process, the friction between the locking bead 113 and the first valve body 110 and the second outer shell 221 can be reduced, which is beneficial to reducing wear and having a long service life. When the first outer shell 121 rotates in the opposite direction relative to the first valve body 110 to close the first flow channel 111, the locking hole 1211 can drive the locking bead 113 to move along the circumferential surface of the first valve body 110 until a part of the structure of the locking bead 113 retracts into the receiving groove 112, so that the first outer shell 121 and the second outer shell 221 can be separated from each other in the axial direction.

[0065] In some embodiments, a plurality of locking holes 1211 distributed along the circumferential direction and a plurality of locking beads 113 corresponding to the locking holes 1211 one by one are provided on the first housing 121, and preferably evenly distributed along the circumferential direction to ensure the balance of force. The axial clamping of the connection end 100 and the docking end 200 is realized by a plurality of locking beads 113, which can effectively improve the connection stability between the two. In addition, in order to facilitate the locking beads 113 to smoothly enter the receiving groove 112 when the first housing 121 and the second housing 221 are docked, a guiding inclined surface 2215 can be provided on the end surface of the second housing 221 facing the first housing 121. When the guiding inclined surface on the second housing 221 contacts the locking bead 113, as the second housing 221 moves axially towards the first housing 121, the guiding inclined surface 2215 on the second housing 221 will push the locking bead 113 into the receiving groove 112. After the connection groove 2213 corresponds to the locking hole 1211, the first housing 121 and the second housing 221 can be rotated synchronously. At this time, under the pushing action of the inner wall of the locking hole 1211 on the locking bead 113, the locking bead 113 will be pushed out of the receiving groove 112. During the process of the locking bead 113 being pushed out, it gradually protrudes from the locking hole 1211 until the locking bead 113 enters between the connection groove 2213 and the outer peripheral surface of the first valve body 110, and then the axial clamping of the first housing 121 and the second housing 221 can be realized. In addition, in order to facilitate the locking bead 113 to move out of the receiving groove 112, a guiding inclined surface 1121 can be provided on one side of the receiving groove 112. When the first flow channel 111 is opened, by rotating the first housing 121, the locking bead 113 will move out of the receiving groove 112 from the guiding inclined surface 1121. When the first flow channel 111 is closed, by rotating the first housing 121 in the reverse direction, the locking bead 113 will enter the receiving groove 112 from the guiding inclined surface 1121.

[0066] In some embodiments, a lock member 212 that can expand and contract radially is provided on the second valve body 210. The lock member 212 can be selected as a spring pin. For example, a receiving cavity 214 for accommodating the spring pin can be provided on the second valve body 210. The head of the lock member 212 can protrude or retract from the receiving cavity 214, and a locking hole 2211 is provided on the second housing 221. When the second housing 221 rotates to a position where the lock member 212 corresponds to the locking hole 2211, the lock member 212 can be clamped in the locking hole 2211, and at this time, the first flow channel 111 and the second flow channel 211 are communicated; when the lock member 212 retracts into the second valve body 210, the second housing 221 can rotate relative to the second valve body 210. Among them, through the lock member 212, after the first flow channel 111 and the second flow channel 211 are communicated, the positions of the first housing 121 and the second housing 221 in the circumferential direction are relatively fixed, so as to prevent the first housing 121 and the second housing 221 from rotating randomly after connecting the fluid connectors, thereby effectively ensuring the stability of the communication state.

[0067] In some embodiments, to facilitate the control of the retraction of the locking member 212 into the second valve body 210, a pressing portion 231 is provided on the second outer shell 221. The pressing portion 231 is used to push the locking member 212 to retract when a pressure is applied. The pressing portion 231 can be a push rod, and the push rod can compress the locking member 212 within the second valve body 210 through the locking hole 2211. When the push rod is removed from the locking hole 2211, the head of the locking member 212 will be clamped within the locking hole 2211 to limit the circumferential rotation of the second housing relative to the second valve body 210.

[0068] In some embodiments, a rubber sleeve 230 is sleeved on the outer periphery of the second outer shell 221. An uneven limiting structure extending in the axial direction can be provided between the inner wall of the rubber sleeve 230 and the outer wall of the second outer shell 221. For example, a limiting groove can be provided on the inner wall of the rubber sleeve 230, and a limiting protrusion can be provided on the outer wall of the second outer shell 221. Through the limiting protrusion and the limiting groove, the circumferential rotation of the rubber sleeve 230 relative to the second outer shell 221 can be restricted. The pressing portion 231 is provided on the rubber sleeve 230. For example, a push rod can be provided inside the rubber sleeve 230. The pressing portion 231 is used to reset under the elastic force of the rubber sleeve 230 when the pressure is removed. In addition, to facilitate the pressing of the pressing portion 231 on the rubber sleeve 230, a conical groove can be provided on the outer peripheral side of the second outer shell 221. When the pressing portion 231 is squeezed, the rubber sleeve 230 will deform towards the conical groove. When the pressing position on the rubber sleeve 230 is released, the pressing portion 231 will rebound outwards to facilitate the extension of the locking member 212 to be clamped within the locking hole 2211.

[0069] In some embodiments, a first pipeline connector 140 is detachably connected to one end of the first valve body 110 away from the first valve 122. The first pipeline connector 140 can be selected as a flare fitting. The first pipeline connector 140 is communicated with the first flow channel 111. A second pipeline connector 240 is detachably connected to one end of the second valve body 210 away from the second valve 222. The second pipeline connector 240 is communicated with the second flow channel 211. The second pipeline connector 240 can be selected as a flare fitting. By detachably connecting the first pipeline connector 140 and the second pipeline connector 240, on the one hand, it is convenient for maintenance, and on the other hand, it is convenient to replace other types of pipeline connectors to improve the adaptability of the fluid connector.

[0070] In some embodiments, to improve the sealing performance of the fluid connector, such as Figure 12As shown in the figure, a first sealing ring 1116 is provided at one end of the first valve body 110 on the connection end 100 facing the first valve 122. A first sealing groove may be provided on the end face of the first valve body 110 facing the first valve 122. The first sealing groove surrounds the first flow channel 111. The first sealing ring 116 is placed in the first sealing groove. By contacting the first valve 122 with the first sealing ring 116, the seal between the first valve 122 and the first valve body 110 can be achieved; a second sealing ring 216 is provided at one end of the second valve body 210 on the docking end 200 facing the second valve 222. A second sealing groove may be provided on the end face of the second valve body 210 facing the second valve 222. The second sealing groove surrounds the second flow channel 211. The second sealing ring 216 is placed in the second sealing ring. By contacting the second valve 222 with the second sealing ring 216, the seal between the second valve 222 and the second valve body 210 can be achieved; in addition, a third sealing ring 223 is provided between the first valve 122 and the second valve 222. The third sealing ring 223 may be provided on the end face of the first valve 122 facing the second valve 222, or may be provided on the end face of the second valve 222 facing the first valve 122. For example, a third sealing groove may be provided on the end face of the second valve 222. The third sealing groove surrounds the second channel 2214. The third sealing ring 223 is placed in the third sealing groove. When the first valve 122 contacts the third sealing ring 223, the seal between the first valve 122 and the second valve 222 can be achieved. In addition, a sealing ring is also provided between the first pipeline joint 140 and the first valve body 110, and a sealing ring is also provided between the second pipeline joint 240 and the second valve body 210 to improve the sealing performance of the fluid connector.
