Description

Technical Field

[0001] This application relates to the technical field of connectors, and more particularly, to a connector and an energy storage device. Background Art

[0002] In the related art, as an important component in a liquid cooling system, a fluid connector mainly functions to quickly connect and disconnect fluid passages such as pipelines and cold plates, facilitating equipment debugging and maintenance, especially in occasions where the equipment needs to be disassembled, assembled, and debugged multiple times. The existing fluid connectors use a ball structure for locking, and two specifications of balls in the ball structure are arranged on the sleeve in an alternating and spaced manner. Therefore, during the assembly process of the balls, it is easy to have material mixing or installation misalignment, such as small balls being installed in the position of large balls or large balls being installed in the position of small balls, reducing the stability of the connector during connection. Summary of the Utility Model

[0003] Embodiments of this application provide a connector and an energy storage device to solve or improve the technical problem that during the assembly process of the balls of a fluid connector, it is easy to have material mixing or installation misalignment, thereby reducing the stability of the connector during connection.

[0004] A connector according to an embodiment of this application includes a plug and a sleeve. Among them, the plug includes a locking portion; the sleeve includes a first rolling bearing, a second rolling bearing, and a first valve body. The first rolling bearing and the second rolling bearing have the same size. The first valve body is provided with an insertion port and a receiving cavity, and the insertion port communicates with the receiving cavity. The first rolling bearing and the second rolling bearing are staggered along the axial direction of the sleeve and are arranged on the cavity wall of the receiving cavity. The first rolling bearing is closer to the insertion port than the second rolling bearing; when the plug is inserted into the receiving cavity, the locking portion abuts against the first rolling bearing and moves, causing the first rolling bearing to drive the second rolling bearing to avoid the locking portion and allowing the plug to be inserted into the sleeve; when the plug is inserted in place, the first rolling bearing separates from the locking portion, and the second rolling bearing abuts against the locking portion to lock the plug in the sleeve.

[0005] In this way, by setting the balls arranged on the sleeve to have the same size, during the assembly of the connector, there is no need to consider the size of the balls, so that the installation can be carried out quickly and there will be no installation misalignment, further improving the stability of the connector during connection.

[0006] In some embodiments, the first valve body includes a plurality of first mounting grooves and a plurality of second mounting grooves, and the first mounting grooves and the second mounting grooves are arranged on the cavity wall of the accommodating cavity at intervals along the circumference of the sleeve, each of the first mounting grooves is installed with a corresponding first rolling bearing, and each of the second mounting grooves is installed with a corresponding second rolling bearing, and a portion of the first rolling bearing and the second rolling bearing are located in the accommodating cavity.

[0007] In this way, by installing the first rolling bearing in the first mounting groove and the second rolling bearing in the second mounting groove, the first rolling bearing and the second rolling bearing can be supported, and the first mounting groove and the second mounting groove are arranged on the cavity wall of the accommodating cavity at circumferential intervals along the sleeve, so that the first rolling bearing and the second rolling bearing can be driven in an orderly manner.

[0008] In some embodiments, the inner angle formed by the axis of the first mounting groove and the axis of the first valve body is an acute angle, and the axis of the second mounting groove is perpendicular to the axis of the first valve body.

[0009] In this way, by setting the first mounting groove as an inclined hole groove on the first valve body, the movement direction of the first rolling bearing can be guided, so that the first axial force and the radial force are generated.

[0010] In some embodiments, the sleeve includes a motion locking ring, a limit piece and a first elastic piece, the first elastic piece connecting the motion locking ring and the limit piece, the end face of the motion locking ring away from the first elastic piece is formed with a first inclined surface, and the first inclined surface is suitable for abutting the first rolling bearing or the second rolling bearing; when the locking portion abuts the first rolling bearing, the first rolling bearing drives the motion locking ring to compress the first elastic piece so that the motion locking ring abuts the limit piece; when the locking portion abuts the second rolling bearing, the first elastic piece drives the motion locking ring to separate from the limit piece.

[0011] In this way, when the plug is inserted into the accommodating cavity, the locking portion abuts against the first rolling bearing so that the first elastic member can be compressed to make the moving locking ring abut against the limiting member, thereby determining the position of the second rolling bearing to avoid the plug.

[0012] In some embodiments, the sleeve further includes an unlocking member connected to the moving locking ring, and the unlocking member is configured to drive the moving locking ring to move back and forth between an unlocking position and a locking position; when the moving locking ring is in the locking position, the first inclined surface abuts against the second rolling bearing so that the second rolling bearing abuts against the locking portion; when the moving locking ring is in the unlocking position, the first inclined surface releases the abutment against the second rolling bearing so that the second rolling bearing releases the abutment against the locking portion.

[0013] Thus, by providing an unlocking member on the sleeve and enabling the unlocking member to move back and forth between the unlocking position and the locking position, the unlocking member can move to the locking position to fix the plug when the plug is inserted into the sleeve, and the unlocking member can move to the unlocking position to unlock the plug when the plug needs to be withdrawn from the sleeve.

[0014] In some embodiments, a convex portion is provided at one end of the unlocking member, and the convex portion is movably connected to the moving locking ring. When the moving locking ring is in the locking position, the convex portion is separated from the moving locking ring. When the moving locking ring is in the unlocking position, the convex portion abuts against the moving locking ring.

[0015] Thus, by providing a convex portion at one end of the unlocking member, when the moving locking ring is in the unlocking position, the convex portion can be made to abut against the moving locking ring under the action of the first elastic member, thereby unlocking the second rolling bearing, and at this time the plug can be separated from the sleeve.

[0016] In some embodiments, the sleeve includes a valve seat and a first seal. The valve seat is provided with a first accommodating cavity, a part of the first valve body extends into the first accommodating cavity, the first seal is arranged between the valve seat and the first valve body, and the valve seat is fixedly connected to the first valve body and is used for connecting a pipeline.

[0017] Thus, by providing a first accommodating cavity in the valve seat, the valve seat and the first valve body partially located in the first accommodating cavity are fixedly connected, so that the first valve body can be fixed. By providing a first seal between the valve seat and the first valve body, the gap between the first valve body and the valve seat can be sealed, preventing fluid from flowing onto other components of the sleeve.

[0018] In some embodiments, the sleeve includes a thimble, a first piston, and a second elastic member. The thimble, the first piston, and the second elastic member are disposed in the accommodation cavity. The thimble penetrates the first piston. The first piston is provided with a first flow channel. The second elastic member connects the first piston and the thimble. When the plug penetrates the accommodation cavity, the plug abuts against the first piston to compress the second elastic member by the first piston, and the end of the thimble away from the second elastic member opens the first flow channel.

[0019] In this way, when the plug penetrates the first accommodation cavity, by disposing the thimble, the first piston, and the second elastic member in the accommodation cavity, when the plug is inserted into the accommodation cavity, the plug can abut against the first piston so that the first piston compresses the second elastic member, and further the end of the thimble away from the second elastic member can open the first flow channel, enabling the fluid to flow through.

[0020] In some embodiments, when the second rolling bearing releases the abutment of the locking portion, the second elastic member is configured to drive the first piston to extrude the plug so that the plug exits the accommodation cavity, and the end of the thimble away from the second elastic member is connected to the first piston to close the first flow channel.

[0021] In this way, when it is necessary to unlock the plug, by transmitting the acting force provided by the reset of the second elastic member to the first piston, the first piston can be made to extrude the plug, quickly extruding the plug out of the accommodation cavity, and the thimble can be reset and connected to the first piston, thereby closing the first flow channel.

[0022] In some embodiments, a second seal is provided on the outer side of the end of the thimble away from the second elastic member. When the plug exits the accommodation cavity, the second seal connects the end of the thimble away from the second elastic member and the surface of the first piston facing the first flow channel, and / or; the sleeve includes a third seal provided on the surface of the first valve body facing the accommodation cavity. When the plug is inserted into the accommodation cavity, the third seal connects the outer side of the plug and the surface of the first valve body facing the accommodation cavity.

[0023] In this way, by providing the second seal, the first flow channel can be sealed when the plug is not inserted into the sleeve or the plug exits the sleeve. By providing the third seal, the gap between the plug and the first valve body can be sealed to prevent the fluid from flowing onto other components.

[0024] In some embodiments, the plug includes a second valve body, a second piston, a third elastic member, and a plug snap ring. The second valve body is provided with a second accommodation cavity, and the second piston, the third elastic member, and the plug snap ring are arranged in the second accommodation cavity. The second piston is provided with a second flow channel, and the third elastic member connects the second piston and the plug snap ring. When the plug penetrates the accommodation cavity, the ejector pin abuts against the second piston to compress the second elastic member by the second piston, and an end of the second piston away from the second valve body opens the second flow channel.

[0025] Thus, when the plug penetrates the accommodation cavity, by providing the second accommodation cavity in the second valve body, the second piston, the third elastic member, and the plug snap ring can be arranged in the second accommodation cavity. Therefore, when the plug is inserted into the accommodation cavity, the ejector pin can abut against the second piston so that the second piston compresses the third elastic member to open the first flow channel, allowing the fluid to flow through.

[0026] In some embodiments, a fourth seal is provided on an outer side of an end of the second piston away from the third elastic member. When the plug exits the accommodation cavity, the fourth seal connects the end of the second piston away from the third elastic member and a surface of the second valve body facing the second flow channel.

[0027] Thus, by providing the fourth seal, the second flow channel can be sealed when the plug is not inserted into the sleeve or the plug exits the sleeve.

Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or reference letters in different examples.

[0050] In the related art, as an important component in a liquid cooling system, a fluid connector mainly functions to achieve rapid on / off of fluid passages such as pipelines and cold plates, facilitating equipment debugging and maintenance, especially in situations where the equipment needs to be disassembled, assembled, and debugged multiple times. The existing fluid connector uses a ball structure for locking, and two specifications of balls in the ball structure are arranged on the sleeve at staggered intervals. Therefore, during the assembly process of the balls, it is easy to have material mixing or installation misalignment, such as a small ball being installed in the position of a large ball or a large ball being installed in the position of a small ball, reducing the stability of the connector during connection.

[0051] To solve the above technical problems, an embodiment of the present application provides a connector 100.

[0052] Please refer to Figure 1 and Figure 2 , a connector 100 according to an embodiment of the present application includes a plug 30 and a sleeve 10. Among them, the plug 30 includes a locking portion 31; the sleeve 10 includes a first rolling bearing 11, a second rolling bearing 12, and a first valve body 13. The first rolling bearing 11 and the second rolling bearing 12 have the same size. The first valve body 13 is provided with an insertion port 131 and a receiving cavity 132, and the insertion port 131 and the receiving cavity 132 are in communication. The first rolling bearing 11 and the second rolling bearing 12 are staggered along the axial direction of the sleeve 10 and are arranged on the cavity wall of the receiving cavity 132. The first rolling bearing 11 is closer to the insertion port 131 than the second rolling bearing 12; when the plug 30 is inserted into the receiving cavity 132, the locking portion 31 abuts against the first rolling bearing 11 and moves, causing the first rolling bearing 11 to drive the second rolling bearing 12 to avoid the insertion of the locking portion 31 into the sleeve 10; when the plug 30 is inserted in place, the first rolling bearing 11 is separated from the locking portion 31, and the second rolling bearing 12 abuts against the locking portion 31 to lock the plug 30 in the sleeve 10.

[0053] In this way, by setting the balls arranged on the sleeve 10 to have the same size, during the assembly of the connector 100, it is not necessary to consider the size of the balls, so that the installation can be carried out quickly and there will be no installation misalignment, further improving the stability of the connector 100 during connection.

[0054] Among them, a liquid cooling system is included in the energy storage device (not marked in the figure). As an important part of the liquid cooling system, the connector 100 mainly functions to quickly open and close fluid passages such as pipelines and cold plates, facilitating equipment debugging and maintenance, especially in occasions where the equipment needs to be disassembled, assembled, and debugged multiple times. For example, the connector 100 can be used for the connection between the liquid cooling system and the server. When the server needs to dissipate heat, the water pipes of the liquid cooling system and the server are connected through the connector 100, so that the low-temperature fluid in the liquid cooling system flows into the server to absorb heat and cool down.

[0055] Specifically, the connector 100 includes a plug 30 and a sleeve 10. The plug 30 can be inserted into and withdrawn from the sleeve 10. When the plug 30 is inserted into the sleeve 10, the connector 100 can be locked to allow fluid to flow through the connector 100; when the plug 30 is withdrawn from the sleeve 10, the connector 100 can be separated to prevent fluid from flowing through the connector 100.

[0056] The shape of the plug 30 can be adapted to the shape of the sleeve 10. For example, when the shape of the sleeve 10 is cylindrical, the shape of the plug 30 is cylindrical and the diameter of the sleeve 10 is larger than that of the plug 30. The plug 30 includes a locking portion 31, and the locking portion 31 is formed on the outer wall of the plug 30. The shape of the locking portion 31 is approximately frustum-shaped. The locking portion 31 can be used to lock the plug 30 when the plug 30 is inserted into the sleeve 10.

[0057] The sleeve 10 includes a first rolling bearing 11, a second rolling bearing 12, and a first valve body 13. The first rolling bearing 11 and the second rolling bearing 12 can be ball bearings or roller bearings, and the sizes of the first rolling bearing 11 and the second rolling bearing 12 are the same. For example, when the first rolling bearing 11 and the second rolling bearing 12 are ball bearings, the diameters of the first rolling bearing 11 and the second rolling bearing 12 are the same; when the first rolling bearing 11 and the second rolling bearing 12 are roller bearings, the lengths and widths of the rectangular cross-sections intercepted along the axis of the first rolling bearing 11 and the second rolling bearing 12 are the same, and the diameters of the circular cross-sections intercepted perpendicular to the axis are the same.

[0058] An insertion port 131 and a receiving cavity 132 are formed on the first valve body 13, and the insertion port 131 can communicate with the receiving cavity 132. Among them, the insertion port 131 can serve as an opening for the plug 30 to be inserted into the sleeve 10, and the receiving cavity 132 can serve as a space for operation when the plug 30 is inserted into the sleeve 10 and locked. Thus, the first rolling bearing 11 and the second rolling bearing 12 can be arranged at intervals along the axial direction of the sleeve 10 in the receiving cavity 132. Thus, a projection part of the first rolling bearing 11 in the circumferential direction of the sleeve 10 falls into the second rolling bearing 12 or does not fall into the second rolling bearing 12 at all. And the first rolling bearing 11 is closer to the insertion port 131 than the second rolling bearing 12.

[0059] When the plug 30 is inserted into the receiving cavity 132 of the first valve body 13, the prism surface of the locking portion 31 can be abutted against the first rolling bearing 11, so that the first rolling bearing 11 can drive the second rolling bearing 12 to move, so that the second rolling bearing 12 can be prevented from contacting the locking portion 31 of the plug 30, that is, the second rolling bearing 12 cannot abut against the locking portion 31, and further the plug 30 can be inserted into the sleeve 10.

[0060] When the plug 30 is inserted into the sleeve 10 and locked, the first rolling bearing 11 can be driven to be separated from the locking portion 31, so that the second rolling bearing 12 can abut against another prism surface of the locking portion 31, and the plug 30 is locked in the sleeve 10.

[0061] Please refer to Figures 3 to 8 In some embodiments, the first valve body 13 includes a plurality of first mounting grooves 14 and a plurality of second mounting grooves 15. The first mounting grooves 14 and the second mounting grooves 15 are arranged at intervals along the circumferential direction of the sleeve 10 on the cavity wall of the receiving cavity 132. Each first mounting groove 14 is provided with a corresponding first rolling bearing 11, and each second mounting groove 15 is provided with a corresponding second rolling bearing 12. A part of the first rolling bearing 11 and the second rolling bearing 12 is located in the receiving cavity 132.

[0062] In this way, by installing the first rolling bearing 11 in the first mounting groove 14 and installing the second rolling bearing 12 in the second mounting groove 15, the first rolling bearing 11 and the second rolling bearing 12 can be supported, and the first mounting grooves 14 and the second mounting grooves 15 are arranged at intervals along the circumferential direction of the sleeve 10 on the cavity wall of the receiving cavity 132, so that the first rolling bearing 11 and the second rolling bearing 12 can be driven orderly.

[0063] Specifically, the first valve body 13 is provided with a plurality of first mounting grooves 14 and a plurality of second mounting grooves 15, for example, the number of the first mounting grooves 14 and the second mounting grooves 15 may be 3 or 6. The first mounting groove 14 can be used to mount the first rolling bearing 11, and the second mounting groove 15 can be used to mount the second rolling bearing 12, so that the first rolling bearing 11 and the second rolling bearing 12 can be arranged on the first valve body 13, and the first valve body 13 can provide support for the movement of the first rolling bearing 11 and the second rolling bearing 12. Among them, the first mounting groove 14 and the second mounting groove 15 are different diameter grooves, that is, the diameter of the end of the first mounting groove 14 and the second mounting groove 15 close to the accommodating cavity 132 is smaller than the diameter of the end away from the accommodating cavity 132, so that when the first rolling bearing 11 and the second rolling bearing 12 are arranged through the first valve body 13, the first rolling bearing 11 and the second rolling bearing 12 can be partially located in the accommodating cavity 132, so that the first rolling bearing 11 and the second rolling bearing 12 can roll in the first mounting groove 14 and the second mounting groove 15 without falling into the accommodating cavity 132.

[0064] The relationship between the notch orientation of the first mounting groove 14 and the axis of the sleeve 10 is different from the relationship between the notch orientation of the second mounting groove 15 and the axis of the sleeve 10, that is, the inner angle formed by the axis of the first mounting groove 14 and the axis of the first valve body 13 is an acute angle, and the first mounting groove 14 is an oblique groove relative to the first valve body 13; the axis of the second mounting groove 15 is perpendicular to the axis of the first valve body 13, that is, the second mounting groove 15 is a straight groove relative to the first valve body 13. In this way, by setting the first mounting groove 14 as an oblique groove on the first valve body 13, the direction of movement of the first rolling bearing 11 can be guided, so that the first axial force and radial force are generated.

[0065] See also Figures 3 to 8 In some embodiments, the sleeve 10 includes a motion locking ring 16, a limit member 17 and a first elastic member 18, the first elastic member 18 connects the motion locking ring 16 and the limit member 17, and the end surface of the motion locking ring 16 away from the first elastic member 18 is formed with a first inclined surface 161, and the first inclined surface 161 is suitable for abutting against the first rolling bearing 11 or the second rolling bearing 12; when the locking portion 31 abuts against the first rolling bearing 11, the first rolling bearing 11 drives the motion locking ring 16 to compress the first elastic member 18 so that the motion locking ring 16 abuts against the limit member 17; when the locking portion 31 abuts against the second rolling bearing 12, the first elastic member 18 drives the motion locking ring 16 to separate from the limit member 17.

[0066] In this way, when the plug 30 is inserted into the accommodating cavity 132 , the locking portion 31 abuts against the first rolling bearing 11 so that the first elastic member 18 can be compressed to make the movable locking ring 16 abut against the limiting member 17 , thereby determining the position of the second rolling bearing 12 to avoid the plug 30 .

[0067] Specifically, the sleeve 10 further includes a movement locking ring 16, a limiting member 17, and a first elastic member 18. Among them, the movement locking ring 16 is circular in shape and is sleeved on the first valve body 13. An inclined surface is formed at one end of the movement locking ring 16 close to the insertion port 131, and the inclined surface can abut against the first rolling bearing 11 or the second rolling bearing 12, so that the first rolling bearing 11 can drive the movement locking ring 16 to move to compress the first elastic member 18, or the movement locking ring 16 abuts against the second rolling bearing 12 under the drive of the first elastic member 18. A convex block is formed at one end of the movement locking ring 16 far from the insertion port 131, and the movement locking ring 16 can abut against the limiting member 17 and the first elastic member 18 through the convex block. The first elastic member 18 can be an elastic spring, such as a helical spring and a rubber spring, etc. The first elastic member 18 can connect the movement locking ring 16 and the first valve body 13, so that the first elastic member 18 can be compressed or reset according to the movement of the movement locking ring 16.

[0068] When the locking portion 31 abuts against the first rolling bearing 11, that is, when the plug 30 is inserted into the receiving cavity 132 of the sleeve 10, since the first valve body 13 is fixed, the first rolling bearing 11 can move along the first installation groove 14 under the abutment of the locking portion 31, so that the first rolling bearing 11 can abut against the inclined surface of the movement locking ring 16, drive the movement locking ring 16 to compress the first elastic member 18, so that the movement locking ring 16 abuts against the limiting member 17, so that the movement locking ring 16 is separated from the second rolling bearing 12, and the second rolling bearing 12 moves along the second installation groove 15 to avoid the locking portion 31. It should be noted that when the movement locking ring 16 is close to the limiting member 17, there is a case where the movement locking ring 16 has been separated from the second rolling bearing 12. At this time, the second rolling bearing 12 can move along the second installation groove 15 to avoid the locking portion 31.

[0069] When the locking portion 31 abuts against the second rolling bearing 12, that is, when the plug 30 is inserted into the receiving cavity 132 of the sleeve 10 and is locked, since the second rolling bearing 12 is far from the insertion port 131 and the first rolling bearing 11 is close to the insertion port 131, at this time, the movement locking ring 16 can be abutted by the second rolling bearing 12, so that the first elastic member 18 is abutted and compressed by the movement locking ring 16, and further the movement locking ring 16 can be separated from the first rolling bearing 11.

[0070] Please refer to Figures 3 to 10, in some embodiments, the sleeve 10 further includes an unlocking member 19. The unlocking member 19 is connected to the moving locking ring 16 and is configured to drive the moving locking ring 16 to move back and forth between an unlocking position and a locking position. When the moving locking ring 16 is in the locking position, the first inclined surface 161 abuts against the second rolling bearing 12 so that the second rolling bearing 12 abuts against the locking portion 31. When the moving locking ring 16 is in the unlocking position, the first inclined surface 161 releases the abutment against the second rolling bearing 12 so that the second rolling bearing 12 releases the abutment against the locking portion 31.

[0071] Thus, by providing the unlocking member 19 on the sleeve 10 and enabling the unlocking member 19 to move back and forth between the unlocking position and the locking position, the unlocking member 19 can move to the locking position to fix the plug 30 when the plug 30 is inserted into the sleeve 10, and the unlocking member 19 can move to the unlocking position to unlock the plug 30 when the plug 30 needs to be withdrawn from the sleeve 10.

[0072] Specifically, the sleeve 10 further includes an unlocking member 19. The unlocking member 19 can be used to unlock the plug 30 and the sleeve 10, so that the connector 100 is separated. Among them, the unlocking member 19 can be fixedly connected to the moving locking ring 16, and the unlocking member 19 can move on the sleeve 10. The moving unlocking member 19 can drive the moving locking ring 16 to move back and forth between the unlocking position and the locking position. The unlocking position is the position where the moving locking ring 16 and the unlocking member 19 are located when unlocking the plug 30 and the sleeve 10, and the locking position is the position where the moving locking ring 16 and the unlocking member 19 are located when locking the plug 30 and the sleeve 10.

[0073] When the moving locking ring 16 is in the locking position, the first inclined surface 161 can abut against the second rolling bearing 12 so that the second rolling bearing 12 abuts against the locking portion 31, and the first rolling bearing 11 can be separated from the inclined surface.

[0074] When the moving locking ring 16 is in the unlocking position, the unlocking member 19 can drive the moving locking ring 16 to compress the first elastic member 18, so that the first inclined surface 161 releases the abutment against the second rolling bearing 12, thereby enabling the second rolling bearing 12 to move along the second installation groove 15 to release the abutment against the locking portion 31, and the plug 30 can be separated from the sleeve 10.

[0075] Please refer to Figures 3 to 10 , in some embodiments, a convex portion 191 is provided at one end of the unlocking member 19. The convex portion 191 is movably connected to the moving locking ring 16. When the moving locking ring 16 is in the locking position, the convex portion 191 is separated from the moving locking ring 16. When the moving locking ring 16 is in the unlocking position, the convex portion 191 abuts against the moving locking ring 16.

[0076] In this way, by providing a convex portion 191 at one end of the unlocking member 19, when the moving locking ring 16 is in the unlocking position, under the action of the first elastic member 18, the convex portion 191 can abut against the moving locking ring 16, thereby unlocking the second rolling bearing 12. At this time, the plug 30 can be separated from the sleeve 10.

[0077] Specifically, a convex portion 191 is provided at one end of the unlocking member 19 close to the first valve body 13, and a part of the convex portion 191 can be movably connected to one end of the moving locking ring 16 close to the insertion port 131.

[0078] For example, when the moving locking ring 16 is in the locking position, the moving locking ring 16 is driven by the first rolling bearing 11 to compress the first elastic member 18, so that the moving locking ring 16 moves axially, so that the convex portion 191 can be separated from the moving locking ring 16.

[0079] For another example, when the moving locking ring 16 is in the unlocking position, the unlocking member 19 can be driven so that the convex portion 191 can abut against the moving locking ring 16 to drive the moving locking ring 16 to move axially to compress the first elastic member 18.

[0080] Please refer to Figure 4 , in some embodiments, the sleeve 10 includes a valve seat 20 and a first seal 22. The valve seat 20 is provided with a first accommodation cavity 21. A part of the first valve body 13 extends into the first accommodation cavity 21. The first seal 22 is arranged between the valve seat 20 and the first valve body 13. The valve seat 20 is fixedly connected to the first valve body 13 and is used for connecting a pipeline.

[0081] In this way, by providing the first accommodation cavity 21 in the valve seat 20, the valve seat 20 and the first valve body 13 partially located in the first accommodation cavity 21 are fixedly connected, so that the first valve body 13 can be fixed. By providing the first seal 22 between the valve seat 20 and the first valve body, the gap between the first valve body 13 and the valve seat 20 can be sealed, preventing fluid from flowing onto other components of the sleeve 10.

[0082] Specifically, the sleeve 10 further includes a valve seat 20 and a first seal 22. The shape of the valve seat 20 can be adapted to the shape of the first valve body 13, so that one end of the valve seat 20 can be used to connect the first valve body 13, and the other end of the valve seat 20 can be used to connect the pipeline through which the fluid flows. The valve seat 20 is provided with a first accommodation cavity 21, and one end of the first valve body 13 can extend into the first accommodation cavity 21, so that the valve seat 20 can fix the first valve body 13.

[0083] The first seal 22 can be a rubber sealing ring or a silicone sealing ring. The first seal 22 is disposed on the inner wall of the valve seat 20, and the first seal 22 is disposed between the valve seat 20 and the first valve body 13. Thus, the first seal 22 can seal the gap between the valve seat 20 and the first valve body 13 to prevent fluid from flowing onto other components of the fluid passage sleeve 10.

[0084] Please refer to Figures 4 to 8 , in some embodiments, the sleeve 10 includes a thimble 23, a first piston 24, and a second elastic member 26. The thimble 23, the first piston 24, and the second elastic member 26 are disposed in the accommodation cavity 132. The thimble 23 passes through the first piston 24. The first piston 24 is provided with a first flow channel 25. The second elastic member 26 connects the first piston 24 and the thimble 23. When the plug 30 passes through the accommodation cavity 132, the plug 30 abuts against the first piston 24 to compress the second elastic member 26 by the first piston 24, and the end of the thimble 23 away from the second elastic member 26 opens the first flow channel 25.

[0085] Thus, when the plug 30 passes through the first accommodation cavity 21, by disposing the thimble 23, the first piston 24, and the second elastic member 26 in the accommodation cavity 132, when the plug 30 passes through the accommodation cavity 132, the plug 30 can abut against the first piston 24 to enable the first piston 24 to compress the second elastic member 26, and further enable the end of the thimble 23 away from the second elastic member 26 to open the first flow channel 25 so that fluid can flow through.

[0086] Specifically, the sleeve 10 further includes a thimble 23, a first piston 24, and a second elastic member 26. Among them, the first valve body 13 is provided with an accommodation cavity 132, and the first accommodation cavity 21 can communicate with the accommodation cavity 132.

The thimble 23 can be disposed through the first piston 24, one end of the second elastic member 26 can be connected to the thimble 23, the other end of the second elastic member 26 can be connected to the first piston 24, and a first flow channel 25 is provided between the thimble 23 and the first piston 24, and the first flow channel 25 can enable fluid to flow through.

[0087] When the plug 30 passes through the accommodation cavity 132, the plug 30 can abut against the first piston 24 to enable the first piston 24 to compress the second elastic member 26, so that the end of the thimble 23 away from the second elastic member 26 can be separated to open the first flow channel 25, so that fluid can flow from the plug 30 into the first flow channel 25.

[0088] Please refer to Figures 11 to 12, in some embodiments, when the second rolling bearing 12 releases the abutment of the locking portion 31, the second elastic member 26 is configured to drive the first piston 24 to extrude the plug 30, so that the plug 30 exits the receiving cavity 132, and the end of the ejector pin 23 away from the second elastic member 26 is connected to the first piston 24 to close the first flow channel 25.

[0089] In this way, when it is necessary to unlock the plug 30, by transmitting the acting force provided by the reset of the second elastic member 26 to the first piston 24, the first piston 24 can be made to extrude the plug 30, quickly extruding the plug 30 out of the receiving cavity 132, and the ejector pin 23 can be reset and connected to the first piston 24, so that the first flow channel 25 can be closed.

[0090] Specifically, when the second rolling bearing 12 releases the abutment of the locking portion 31, that is, when it is necessary to withdraw the plug 30 from the sleeve 10, the second rolling bearing 12 can release the abutment of the locking portion 31. At this time, the second elastic member 26 can provide the acting force required for reset to the first piston 24, and the first piston 24 can transmit the acting force to the plug 30, so that the plug 30 exits the receiving cavity 132, and thus the plug 30 is separated from the sleeve 10. And when the first piston 24 is reset, the end of the ejector pin 23 away from the second elastic member 26 can be connected to the first piston 24, so that the first flow channel 25 is closed.

[0091] Please refer to Figures 6 to 10 , in some embodiments, a second seal 27 is provided on the outer side of the end of the ejector pin 23 away from the second elastic member 26. When the plug 30 exits the receiving cavity 132, the second seal 27 connects the end of the ejector pin 23 away from the second elastic member 26 and the surface of the first piston 24 facing the first flow channel 25, and / or; the sleeve 10 includes a third seal 28, and the third seal 28 is provided on the surface of the first valve body 13 facing the receiving cavity 132. When the plug 30 is inserted into the receiving cavity 132, the third seal 28 connects the outer side of the plug 30 and the surface of the first valve body 13 facing the receiving cavity 132.

[0092] In this way, by providing the second seal 27, the first flow channel 25 can be sealed when the plug 30 is not inserted into the sleeve 10 or the plug 30 exits the sleeve 10. By providing the third seal 28, the gap between the plug 30 and the first valve body 13 can be sealed, preventing fluid from flowing onto other components.

[0093] Specifically, a second seal 27 is provided at the end of the thimble 23 away from the second elastic member 26. The second seal 27 can be a rubber sealing ring or a silica gel sealing ring, etc. The second seal 27 can seal the gap between the first piston 24 and the thimble 23. Thus, when the plug 30 exits the receiving cavity 132, the second seal 27 can connect the end of the thimble 23 away from the second elastic member 26 and the surface of the first piston 24 facing the first flow channel 25, so that the first flow channel 25 is sealed.

[0094] The sleeve 10 further includes a third seal 28. The third seal 28 can be a rubber sealing ring or a silica gel sealing ring, etc. The third seal 28 is provided on the surface of the first valve body 13 facing the receiving cavity, that is, on the inner wall of the first valve body 13. A part of the third seal 28 can extend into the receiving cavity. When the plug 30 is inserted into the receiving cavity, the third seal 28 can connect the outer side of the plug 30 and the surface of the first valve body 13 facing the receiving cavity to seal the gap between the plug 30 and the first valve body 13 and prevent fluid from entering other components of the sleeve 10.

[0095] Please refer to Figure 6 、 Figure 11 and Figure 12 In some embodiments, the plug 30 includes a second valve body 32, a second piston 34, a third elastic member 36 and a plug snap ring 37.

The second piston 34, the third elastic member 36 and the plug snap ring 37 are arranged in the second accommodation cavity 33. The second piston 34 is provided with a second flow channel 35. The third elastic member 36 connects the second piston 34 and the plug snap ring 37. When the plug 30 passes through the receiving cavity 132, the thimble 23 abuts against the second piston 34 to compress the second elastic member 26 by the second piston 34, and the end of the second piston 34 away from the second valve body 32 opens the second flow channel 35.

[0096] In this way, when the plug 30 passes through the first accommodation cavity 21, by providing the second accommodation cavity 33 in the second valve body 32, the second piston 34, the third elastic member 36 and the plug snap ring 37 can be arranged in the second accommodation cavity 33. Thus, when the plug 30 is inserted into the second accommodation cavity 33, the thimble 23 can abut against the second piston 34 to compress the third elastic member 36 by the second piston 34 to open the first flow channel 25, so that the fluid can flow through.

[0097] Specifically, the plug 30 further includes a second valve body 32, a second piston 34, a third elastic member 36, and a plug snap ring 37. Among them, the shape of the second valve body 32 is adapted to the shape of the sleeve 10, so that the second valve body 32 can successively enter the accommodation cavity 132 and the second accommodation cavity 33. The second valve body 32 is further provided with a second accommodation cavity 33, and the second accommodation cavity 33 can be used to accommodate the second piston 34, the third elastic member 36, and the plug snap ring 37.

[0098] The end of the second piston 34 away from the third elastic member 36 can be connected to the second valve body 32 to seal the second accommodation cavity 33. A second flow channel 35 is provided on the second piston 34, and the second flow channel 35 can communicate with the first flow channel 25, so that the fluid flows from the second flow channel 35 into the first flow channel 25.

One end of the third elastic member 36 can be connected to the second piston 34, and the other end of the third elastic member 36 can be connected to the plug snap ring 37. The plug snap ring 37 is fixed on the valve seat 20 of the plug 30, so that the third elastic member 36 can abut against the plug snap ring 37 when compressed.

[0100] When the plug 30 extends into the sleeve 10 and passes through the second accommodation cavity 33, the valve seat 20 of the plug 30 can abut against the first piston 24, so that the second elastic member 26 is compressed. Thus, during the movement of the plug 30 extending into the second accommodation cavity 33, the ejector pin 23 can abut against the second piston 34, so that the second piston 34 can compress the second elastic member 26. As a result, the end of the second piston 34 away from the second valve body 32 is separated from the second valve body 32, so that the second flow channel 35 communicates with the first flow channel 25.

[0101] Please refer to Figure 12 , in some embodiments, a fourth seal 38 is provided on the outer side of the end of the second piston 34 away from the third elastic member 36. When the plug 30 exits the accommodation cavity 132, the fourth seal 38 connects the end of the second piston 34 away from the third elastic member 36 and the surface of the second valve body 32 facing the second flow channel 35.

[0102] In this way, by providing the fourth seal 38, the second flow channel 35 can be sealed when the plug 30 is not inserted into the sleeve 10 or the plug 30 exits the sleeve 10.

[0103] Specifically, the plug 30 further includes a fourth seal 38. The fourth seal 38 can be a rubber sealing ring or a silicone sealing ring. The fourth seal 38 is provided on the outer side of the end of the second piston 34 away from the third elastic member 36, and a part of the fourth seal 38 can extend into the second accommodation cavity 33.

[0104] When the plug 30 exits the receiving cavity 132, the second piston 34 can be connected to the second valve body 32 under the action of the third elastic member 36, so that the fourth seal 38 can connect the end of the second piston 34 away from the third elastic member 36 and the surface of the second valve body 32 facing the second flow channel 35, so that the gap between the second piston 34 and the second valve body 32 is sealed, that is, the fourth seal 38 can seal the second flow channel 35 to prevent fluid from flowing out of the second flow channel 35.
