Description
Technical Field
[0001] This utility model relates to the field of fluid connection technology, and in particular to a connection end, a fluid connector, and a liquid cooling system. Background Technology
[0002] A fluid connector mainly consists of two connectors. These two connectors can have the same or different structures and are connected by mating. For ease of description, one connector is generally called the connecting end, and the other connector that mates with the connecting end is called the mating end.
[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: In the existing system, the valve cover with the fixed axial locking component needs to move relative to another valve cover with a connecting groove in order to achieve axial locking of the two valve covers, thereby enabling a reliable axial connection between the connecting end and the mating end. However, the relative movement of the two valve covers is inconvenient.
[0004] Therefore, how to effectively ensure that the axial locking of the connecting end and the mating end is relatively convenient is a technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0005] The purpose of this invention is to provide a connecting end, a fluid connector, and a liquid cooling system to effectively ensure that the axial locking of the connecting end and the mating end is convenient.
[0006] To achieve the above objectives, the present invention provides a connecting end for connecting to a mating end having a connecting groove. The connecting end includes an axial locking member, a first valve cover, and a first valve body. The first valve body has a receiving groove located inside the first valve cover. The first valve cover includes a pushing part and a clearance area corresponding to the receiving groove. The clearance area and the receiving groove are used to accommodate the axial locking member. The first valve cover can move relative to the first valve body to an open state, and the pushing part pushes the axial locking member out of the receiving groove, and part of the axial locking member moves radially along the clearance area to the outside of the first valve cover to extend into the connecting groove.
[0007] In one possible design, a receiving groove is formed on the outer peripheral surface of the first valve body, and a radially extending locking hole is formed on the outer peripheral surface of the first valve cover to form a clearance area, and the inner wall of the locking hole forms a pushing part that contacts the axial locking member.
[0008] In one possible design, the first valve body is provided with a first flow channel, and the first valve cover includes a valve rotatably connected to one side of the first valve body, and the valve is provided with a through hole;
[0009] When the axial locking part is located in the receiving groove, the first flow channel and the through hole are disconnected.
[0010] When the axial locking member abuts against the outer peripheral surface of the first valve body, and the first valve cover rotates relative to the first valve body to a preset position, the first flow channel and the through hole are connected and in an open state.
[0011] In one possible design, the clearance area has a first opening toward the first valve body and a second opening away from the first valve body;
[0012] The diameter of the first opening's projection surface in the direction of the clearance zone extension, and the diameter of the axial locking component's projection surface in the direction of the clearance zone extension, are both larger than the diameter of the second opening's projection surface in the direction of the clearance zone extension.
[0013] In one possible design, the receiving groove is provided with a guide surface for contacting the axial locking member toward the side of the first valve body, and the guide surface is located in the rotation direction of the first valve cover, so that when the first valve cover rotates relative to the first valve body, the guide surface guides the movement of the axial locking member in the receiving groove.
[0014] In one possible design, the guide surface is connected to the bottom of the receiving groove and the circumferential surface of the first valve body, and the guide surface is radially inclined relative to the first valve body.
[0015] In one possible design, the axial locking member includes a first end facing away from the first valve body and a second end facing away from the first end.
[0016] The second end extends out of the first opening, or the first end extends out of the second opening;
[0017] Furthermore, when the second end contacts the bottom of the receiving groove, the first end is located within the clearance area; when the second end contacts the circumferential surface of the first valve body, the first end extends out of the clearance area.
[0018] In one possible design, the receiving grooves are evenly distributed in the circumferential direction of the first valve body;
[0019] The clearance areas are evenly distributed around the first valve cover and the number of clearance areas corresponds to the number of receiving grooves. Each clearance area is in contact with an axial locking element.
[0020] In one possible design, the axial locking element includes a spherical ball.
[0021] A fluid connector includes a mating end and a connecting end as described above. The mating end includes a second valve cover with a mating portion. A connecting groove is formed on the inner circumferential surface of the mating portion. The second valve cover and a first valve cover are axially movable towards each other so that the mating portion is fitted onto the outer circumference of the first valve cover. The connecting groove is used to accommodate a portion of the axial locking member that moves radially outward along the clearance area to the outside of the first valve cover, so that the second valve cover and the first valve cover are connected.
[0022] In one possible design, the mating part has an inclined surface on the side facing the first valve cover in the axial direction. The inclined surface is set at an angle to the axial direction. The inclined surface is used to contact the axial locking part extending out of the first valve cover on the side facing the second valve cover when the second valve cover moves axially toward the first valve cover, so as to drive the axial locking part to move toward the first valve body.
[0023] In one possible design, the connecting groove has an abutment surface on the side facing the first valve cover in the axial direction. The abutment surface is set at an angle to the axial direction and is used to abut against a portion of the axial locking member that moves radially into the connecting groove along the clearance area, so as to limit the second valve cover and the first valve cover from moving away from each other in the axial direction.
[0024] In one possible design, the docking end also includes a second valve body, which is disposed inside a second valve cover. The second valve cover has a second flow channel, which is used to communicate with the first flow channel on the first valve body.
[0025] A liquid cooling system includes a fluid conduit and a connection end as described above, wherein a first valve body is in communication with the fluid conduit.
[0026] Compared with the prior art, the technical solution provided by this utility model has at least the following advantages:
[0027] This application employs a radially movable axial locking component to achieve axial locking directly through radial movement of the axial locking component relative to the first valve cover. The radial movement of the axial locking component is achieved by the pushing part of the first valve cover moving out of the receiving groove during the process of the first valve cover moving relative to the first valve body into an open state, thereby changing the radial position of the axial locking component. This causes part of the axial locking component to move radially along the clearance area to the outside of the first valve cover and extend into the connecting groove of the mating end, thus restricting the relative axial movement between the connecting end and the mating end. This eliminates the need for the two valve covers to move relative to each other and for the first valve cover to move relative to the first valve body into an open state to complete the axial locking of the connecting end and the mating end, effectively ensuring that the axial locking of the connecting end and the mating end is more convenient.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0044] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0045] In the description of this utility model, it should be understood that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.
[0046] The purpose of this invention is to provide a connecting end, a fluid connector, and a liquid cooling system to effectively ensure that the axial locking of the connecting end and the mating end is convenient.
[0047] Please see Figure 1 and Figure 2 To achieve the above objectives, this utility model provides a connecting end for connecting to a mating end with a connecting groove 320. The connecting end includes an axial locking member 120, a first valve cover 100, and a first valve body 200. The first valve body 200 has a receiving groove 210 located within the first valve cover 100. The first valve cover 100 includes a pushing part and a clearance area 110 corresponding to the receiving groove 210. The clearance area 110 and the receiving groove 210 are used to accommodate the axial locking member 120. The first valve cover 100 can move relative to the first valve body 200 to an open state, and the pushing part pushes the axial locking member 120 out of the receiving groove 210, and part of the axial locking member 120 moves radially along the clearance area 110 to the outside of the first valve cover 100 to extend into the connecting groove 320. The first valve cover 100 has a receiving cavity, and the side of the receiving cavity opposite to the docking end has an inlet for partially or completely inserting the first valve body 200 into the receiving cavity, so that the receiving groove 210 is located in the receiving cavity. The connecting end also includes a first connecting cap 500, which is threadedly connected to the inlet to restrict the reverse disengagement of the first valve body 200, thereby achieving relative axial stability between the first valve body 200 and the first valve cover 100. A radial limiting member can also be added between the first valve body 200 and the first valve cover 100 to ensure that the movement of the first valve cover 100 relative to the first valve body 200 is within a certain range.
[0048] Please see Figure 5 , Figure 6 and Figure 7The axial locking member 120 is accommodated by the clearance area 110 of the first valve cover 100 and the receiving groove 210 of the first valve body 200, effectively restricting the axial movement of the first valve body 200 relative to the first valve cover 100. During the process of the first valve cover 100 moving relative to the first valve body 200 to the open state, the pushing part can push the axial locking member 120 to move radially relative to the first valve cover 100. The radially movable axial locking member 120 is used to achieve axial locking directly by the radial movement of the axial locking member 120 relative to the first valve cover 100. The radial movement of the axial locking member 120 is achieved by means of the first valve cover 100... During the process of the first valve body 200 being in the open state, the pushing part of the first valve cover 100 drives the axial locking member 120 to move out of the receiving groove 210 to change the radial position of the axial locking member 120. This causes part of the axial locking member 120 to move radially along the avoidance area 110 to the outside of the first valve cover 100 and extend into the connecting groove 320 of the mating end. This restricts the relative axial movement between the connecting end and the mating end. The axial locking of the connecting end and the mating end is completed without the two valve covers moving relative to each other and by means of the first valve cover 100 being in the open state relative to the first valve body 200. This effectively ensures that the axial locking of the connecting end and the mating end is more convenient.
[0049] In one embodiment, the receiving groove 210 is formed on the outer peripheral surface of the first valve body, and the outer peripheral surface of the first valve cover has a radially extending locking hole to form a clearance area 110. The inner wall of the locking hole forms a pushing part that contacts the axial locking member 120. By setting the receiving groove 210 on the outer peripheral surface of the first valve body 200, the axial locking member 120 is moved out of the receiving groove 210 and directly contacts the outer peripheral surface of the first valve body 200. It is then pushed up by the circumferential surface of the first valve body 200, changing the radial position of the axial locking member 120. This causes a portion of the axial locking member 120 to move radially along the clearance area 110 to the outside of the first valve cover 100 and extend into the connecting groove 320. The outer peripheral surface of the first valve cover 100 has a radially extending locking hole to form a clearance area. 110, so that before the first valve cover 100 moves, the clearance area 110 corresponds radially to the receiving groove 210, so that when the first valve cover 100 moves the clearance area 110 relative to the receiving groove 210, the pushing part contacts the axial locking member 120 and pushes the axial locking member 120 to move radially relative to the first valve body 200. It should be noted that the docking part of the docking end is usually sleeved on the outer periphery of the first valve cover 100 for docking with the connecting end. The connecting groove 320 can be set on the inner wall of the docking part so that the axial locking member 120 can directly enter the connecting groove 320 after radial extension, so as to effectively ensure the reliable connection between the connecting end and the docking end in the axial direction. Here, the axial direction refers to the direction in which the connecting end and the docking end approach and move away from each other.
[0050] Please see Figure 4In one embodiment, the first valve body 200 is provided with a first flow channel 220, and the first valve cover 100 includes a valve 130 rotatably connected to one side of the first valve body 200 for controlling the opening and closing of the first flow channel 220. This rotatable connection can be a direct connection or an indirect rotatable connection via a sealing ring. The first valve cover 100 can be configured as an integral structure including the valve 130. The valve 130 is provided with a through hole 140. The movement of the first valve cover 100 can cause the valve 130 to move synchronously, thereby changing the position of the through hole 140 relative to the first valve body 200, that is, changing the position of the through hole 140. The position relative to the first flow channel 220 is such that the through hole 140 on the first valve cover 100 is aligned with or offset from the first flow channel 220 on the first valve body 200. When the axial locking member 120 is located in the receiving groove 210, the first flow channel 220 and the through hole 140 are not connected and are in a disconnected state. The movement of the first valve cover 100 can preferably be the rotation of the first valve cover 100 relative to the first valve body 200. When the axial locking member 120 abuts against the outer peripheral surface of the first valve body and the first valve cover 100 rotates relative to the first valve body 200 to a preset position, the first flow channel 220 and the through hole 140 are connected and are in an open state.
[0051] The rotation range of the first valve cover 100 relative to the first valve body 200 can be divided into a first rotation range and a second rotation range, and the first rotation range and the second rotation range are continuous. When the first valve cover 100 rotates relative to the first valve body 200 within the first rotation range, the first flow channel 220 is not connected to the through hole 140 of the valve 130 and is in a disconnected state. When the first valve cover 100 rotates relative to the first valve body 200 within the second rotation range, the first flow channel 220 is connected to the through hole 140 and is in an open state. When the axial locking member 120 is simultaneously located in the receiving groove 210 and the clearance area 110, the first valve cover 100 is within the first rotation range relative to the first valve body 200. When the first valve cover 100 is within the second rotation range relative to the first valve body 200, the axial locking member 120 contacts the circumferential surface of the first valve body 200 and partially extends out of the clearance area 110 to connect to the connecting groove 320.
[0052] Please see Figure 4In one embodiment, the number of through holes 140 and first flow channels 220 provided on the connecting end can be two. The two through holes 140 are eccentrically positioned relative to the rotation axis of the first valve cover 100, and the two first flow channels 220 are eccentrically positioned relative to the rotation axis of the first valve cover 100. The positions of the through holes 140 and the first flow channels 220 correspond so that the states of the two sets of through holes 140 and first flow channels 220 are consistent. That is, when one through hole 140 and one first flow channel 220 are connected and in an open state, the other through hole 140 and another first flow channel 220 are connected and in an open state; when one through hole 140 and one first flow channel 220 are not connected and in a disconnected state, the other through hole 140 and another first flow channel 220 are not connected and in a disconnected state.
[0053] In one embodiment, the axial locking member 120 can be a spherical ball. The axial locking member 120 can be, but is not limited to, a spherical ball. That is, the axial locking member 120 can move and roll. By rolling the axial locking member 120 relative to the receiving groove 210 and the circumferential surface of the first valve body 200, the friction of the axial locking member 120 during the process of moving to different positions can be reduced, the moving efficiency of the axial locking member 120 can be improved, the wear of the axial locking member 120 can be reduced, and the service life of the axial locking member 120 can be extended.
[0054] In one embodiment, the clearance area 110 has a first opening facing the first valve body 200 and a second opening away from the first valve body 200; the first opening is for a portion of the axial locking member 120 to extend out of the clearance area 110 to the receiving groove 210 or the circumferential surface of the first valve body 200, and the second opening is for a portion of the axial locking member 120 to extend out of the first valve cover 100. The diameter of the projected surface of the first opening in the extending direction of the clearance area 110 and the diameter of the projected surface of the axial locking member 120 in the extending direction of the clearance area 110 are both larger than the diameter of the projected surface of the second opening in the extending direction of the clearance area 110. The first opening can be... The diameter of the projected surface of the clearance area 110 in the extending direction is set to be larger than the diameter of the projected surface of the axial locking member 120 in the extending direction of the clearance area 110, so as to assemble the axial locking member 120 into the clearance area 110. At the same time, the projection surface of the axial locking member 120 in the extending direction of the clearance area 110 is larger than the diameter of the projection surface of the second opening in the extending direction of the clearance area 110, so as to effectively restrict the axial locking member 120 from completely disengaging from the clearance area 110 from the second opening. The clearance area 110 can be set as a cylindrical lock hole with a constricted structure, and the constricted structure is located at the second opening to adapt to the axial locking member 120 using a spherical bead.
[0055] It should be noted that the inner wall of the cylindrical locking hole forms a pushing part that contacts the axial locking member 120. When the axial locking member 120 using a spherical ball is in different radial positions, the pushing part is different parts of the inner wall of the cylindrical locking hole. The inner wall of the cylindrical locking hole can be divided into a lower half near the receiving groove 210 and an upper half away from the receiving groove 210. For example, when the axial locking member 120 is partially located in the receiving groove 210, it can contact the axial locking member 120 through the lower half of the inner wall of the cylindrical locking hole. As the pushing part of the axial locking member 120 in the initial state when the first valve cover 100 is not rotated; when the axial locking member 120 contacts the circumferential surface of the first valve body 200, it can contact the axial locking member 120 through the upper half of the inner wall of the cylindrical lock hole as the pushing part of the axial locking member 120 in the standard state; during the switching process between the initial state and the standard state, the contact between the axial locking member 120 and the lower half of the inner wall of the cylindrical lock hole is changed to the contact between the axial locking member 120 and the upper half of the inner wall of the cylindrical lock hole.
[0056] In one embodiment, the receiving groove 210 is provided with a guide surface 211 for contacting the axial locking member 120 on the side facing the first valve body 200. The guide surface 211 is located in the rotation direction of the first valve cover 100, so that when the first valve cover 100 rotates relative to the first valve body 200, the guide surface 211 guides the movement of the axial locking member 120 within the receiving groove 210. The guide surface 211 guides both the circumferential rotation of the axial locking member 120 relative to the first valve body 200 under the action of the pushing part when the first valve cover 100 rotates, and the radial movement of the axial locking member 120 relative to the first valve body 200 under the action of the pushing part when the first valve cover 100 rotates. The guide surface 211 effectively prevents the axial locking member 120 from deviating from the preset path during the movement driven by the pushing part, making it easier for the axial locking member 120 to move out of the receiving groove 210.
[0057] In one embodiment, the guide surface 211 is connected to the bottom of the receiving groove 210 and the circumferential surface of the first valve body 200, and the guide surface 211 is radially inclined relative to the first valve body 200. This allows the guide surface 211 to have a certain slope relative to the radial direction of the first valve body 200. This slope enables the axial locking member 120 to gradually move towards the second opening direction at one end near the first valve body 200 during the process of the axial locking member 120 moving out of the receiving groove 210. When the end of the axial locking member 120 near the first valve body 200 is in contact with the circumferential surface of the first valve body 200, the end of the axial locking member 120 near the first valve body 200 moves to the minimum distance between itself and the second opening. Simultaneously, when the push... When the axial locking member 120 is driven in the reverse direction and moves from the circumferential surface of the first valve body 200 to the bottom of the receiving groove 210, the guide surface 211 enables the end of the axial locking member 120 near the first valve body 200 to gradually move from the circumferential surface of the first valve body 200 to the bottom of the receiving groove 210. The guide surface 211 is also set at an angle to the moving direction of the axial locking member 120, which is conducive to the rolling of the axial locking member 120, which is set as a ball, and improves the moving efficiency of the axial locking member 120.
[0058] In one embodiment, the axial locking member 120 includes a first end facing away from the first valve body 200 and a second end facing away from the first end. The first and second ends can be in fixed positions when the axial locking member 120 is stationary, and are in relative positions to the first valve body 200 when the axial locking member 120 rotates. For example, when the axial locking member 120 is a spherical bead, and the spherical bead rotates, regardless of its rotation state, it will always have a first end facing away from the first valve body 200 and a second end facing away from the first end. The second end extends out of the first opening, or the first end extends out of the second opening; that is, the axial locking member 120 is positioned relative to the first valve body 200. The maximum radial length is greater than the radial length of the clearance hole in the first valve body 200, and when the second end contacts the bottom of the receiving groove 210, the first end is located within the clearance area 110, so as to ensure that the axial locking member 120 can be completely housed between the second opening and the bottom of the receiving groove 210, and to prevent the axial locking member 120 from extending out of the second opening and interfering with the docking process of the mating end and the connecting end moving towards each other; when the second end contacts the circumferential surface of the first valve body 200, the first end extends out of the clearance area 110, so as to ensure that the second end can extend into the connecting groove 320 after the axial locking member 120 moves out of the receiving groove 210, thus restricting the axial separation of the connecting end and the mating end.
[0059] In one embodiment, the receiving grooves 210 are uniformly arranged in the circumferential direction of the first valve body 200; the clearance areas 110 are uniformly arranged in the circumferential direction of the first valve cover 100 and are consistent with the number of receiving grooves 210, and each clearance area 110 is in contact with an axial locking member 120. The circumferentially evenly distributed receiving grooves 210 and clearance areas 110 correspond one-to-one, effectively ensuring that the states of the axial locking members 120 are consistent. That is, when the first valve cover 100 rotates around the rotation axis, the pushing part formed on the inner wall of the clearance area 110 can drive the axial locking member 120 connected to it to move out of the receiving groove 210 and contact the circumferential surface of the first valve body 200. When the first valve cover 100 rotates in the opposite direction around the rotation axis, the pushing part formed on the inner wall of the clearance area 110 can drive the axial locking member 120 connected to it to move from the circumferential surface of the first valve body 200 into the receiving groove 210. The circumferentially evenly distributed receiving grooves 210, clearance areas 110, and axial locking members 120 that can contact the inner wall of the clearance area 110 can make the first valve body 200 and the first valve cover 100 be subjected to uniform force in all directions when they are fastened or compressed.
[0060] Please see Figure 2 and Figure 3 Based on the above, this utility model also provides a fluid connector, including a mating end and a connecting end as described above. The mating end includes a second valve cover 300 with a mating portion 310. A connecting groove 320 is provided on the inner circumferential surface of the mating portion 310. The connecting groove 320 can be an arc groove or an annular groove. The second valve cover 300 and the first valve cover 100 can move towards each other along the axial direction so that the mating portion 310 is sleeved on the outer circumference of the first valve cover 100. The connecting groove 320 is used to accommodate a portion of the axial locking member 120 that moves radially along the avoidance area 110 to the outside of the first valve cover 100 and abuts against the side of the axial locking member 120 away from the second valve cover 300 to restrict the second valve cover 300 and the first valve cover 100 from moving away from each other, so that the second valve cover 300 and the first valve cover 100 are connected.
[0061] When the first valve cover 100 and the second valve cover 300 are mated, the receiving groove 210 is located inside the first valve cover 100, and the mating portion 310 of the second valve cover 300 is located on the outer periphery of the first valve cover 100. The first valve cover 100 has a clearance area 110 corresponding to the receiving groove 210, allowing the clearance area 110 and the receiving groove 210 to accommodate the axial locking member 120. The axial locking member 120 is not subjected to the supporting force extending into the connecting groove 320. The first valve cover 100 needs to move relative to the first valve body 200, allowing the through hole 140 of the valve 130 to engage with the first valve body 200. The first flow channel 220 is connected so that the first flow channel 220 is in an open state. During the relative rotation, the pushing part of the first valve cover 100 can drive the axial locking member 120 to disengage from the receiving groove 210, thereby changing the radial position of the axial locking member 120. This causes the axial locking member 120 to extend into the connecting groove 320 and abut against the side of the connecting groove 320 near the first valve body 200 in the mating direction of the first valve cover 100 and the second valve cover 300, thereby limiting the first valve cover 100 and the second valve cover 300 from moving away from each other in the axial direction and ensuring a reliable connection of the fluid connector.
[0062] In one embodiment, the docking portion 310 has an inclined surface 330 on the side facing the first valve cover 100 in the axial direction. The inclined surface 330 is set at an angle to the axial direction. The inclined surface 330 is used to contact the side of the axial locking member 120 extending out of the first valve cover 100 facing the second valve cover 300 when the second valve cover 300 moves axially toward the first valve cover 100, so as to drive the axial locking member 120 to move toward the first valve body 200. It is understood that the axial locking member 120 can move radially within the clearance area 110. Even if the clearance area 110 corresponds to the receiving groove 210, the axial locking member 120 may also move radially under other factors (e.g., gravity) to partially extend beyond the clearance area 110, affecting the axial docking process of the second valve cover 300 and the first valve cover 100. During the movement of the docking part 310 toward the first valve cover 100, the inclined surface 330 is provided so that when the inclined surface 330 translates in the axial direction (dating direction), it can contact the end of the axial locking member 120 away from the receiving groove 210 and drive the axial locking member 120, which partially extends beyond the clearance area 110, to move toward the receiving groove 210, so as to effectively ensure that the docking part 310 moves smoothly to the outer periphery of the first valve cover 100.
[0063] In one embodiment, the connecting groove 320 has an abutment surface 340 on the side facing the first valve cover 100 in the axial direction. The abutment surface 340 is angled to the axial direction and is used to abut against a portion of the axial locking member 120 that moves radially into the connecting groove 320 along the avoidance area 110, thereby restricting the second valve cover 300 and the first valve cover 100 from moving away from each other in the axial direction. At the same time, when it is necessary to separate the mating end and the connecting end, the axial locking member 120 can be rotated from the contact surface of the first valve body 200 by the opposite movement of the first valve cover 100 relative to the first valve body 200 under the push of the pushing part. The axial locking member 120 may also move radially under other factors (e.g., gravity) to partially extend beyond the clearance area 110 (separating from the contact of the receiving groove 210), affecting the axial separation process of the second valve cover 300 and the first valve cover 100. At this time, when the abutment surface 340 translates in the axial direction (separation direction), it can contact the end of the axial locking member 120 away from the receiving groove 210 and drive the axial locking member 120, which partially extends beyond the clearance area 110, to move toward the receiving groove 210, so as to effectively ensure the separation of the docking part 310 and the connecting part.
[0064] In one embodiment, the mating end further includes a second valve body 400, which is disposed within a second valve cover 300 and is rotatable relative to the second valve body 400. The second valve cover 300 has a second flow channel 410, which communicates with a first flow channel 220 on the first valve body 200. The number of second flow channels 410 and first flow channels 220 is the same. The second valve cover 300 has a chamber, and the side of the chamber opposite to the connecting end has an inlet for partially or completely inserting the second valve body 400 into the chamber. The mating end also includes a second connecting cap 600, which is threadedly connected to the inlet to restrict the opposite disengagement of the second valve body 400, thereby achieving relative axial stability between the second valve body 400 and the second valve cover 300. The second flow channel 410 is used to communicate with the first flow channel 220 on the first valve body 200. During the connection process between the connecting end and the docking end, the protrusion and groove provided between the first valve cover 100 and the docking part 310 can enable the first valve cover 100 and the second valve cover 300 to rotate synchronously. At this time, the rotation of the first valve cover 100 relative to the first valve body 200 and the rotation of the second valve cover 300 relative to the second valve body 400 can be achieved by rotating the first valve cover 100 alone. This allows the second flow channel 410 of the second valve body 400 to be connected. 10 is coaxially arranged with the first flow channel 220 of the first valve body 200, such that when the through hole 140 of the valve 130 is connected to the first flow channel 220 of the first valve body 200 and the second flow channel 410 of the second valve body 400, the first flow channel 220 and the second flow channel 410 are in an open state of connection, and when the through hole 140 of the valve 130 is not connected to the first flow channel 220 of the first valve body 200 and the second flow channel 410 of the second valve body 400, the first flow channel 220 and the second flow channel 410 are in a closed state of non-connection.
[0065] In addition, this utility model also provides a liquid cooling system, which includes a fluid pipe and the above-mentioned connecting end. The liquid cooling system also has all the beneficial effects of the above-mentioned connecting end. The first valve body 200 is connected to the fluid pipe for liquid flow. The liquid includes, but is not limited to, a cooling medium. The other components of the liquid cooling system can be referred to the prior art, and will not be described in detail here.
