Connecting end, piping connector, and liquid cooling system

Abstract

A connecting end, a piping connector, and a liquid cooling system, wherein the connecting end comprises a valve seat, a valve element, and a locking pin, the valve element being rotationally arranged on the valve seat to open and close a flow channel of the valve seat, the locking pin being capable of moving in an axial direction of a rotational axis of the valve element, and, when moving to a first position in a first axial direction, preventing the valve element from rotating relative to the valve seat; the locking pin can rotate to enter a limiting position when moving to a second position in a second axial direction to disengage from the first position. The valve seat is provided with a guiding portion, and a pushing portion is arranged on the valve element. When the valve element rotates relative to the valve seat, the locking pin moves in the second axial second direction from the second position to a preset stroke, and in the process of moving, the guiding portion guides the rotation of the locking pin, so as to exit the limiting position. Since the locking pin exits the limiting position while the valve element is in the process of rotating, a user does not need to perform any further operations to remove the locking pin from the limiting position after rotating the valve element, thereby reducing the operational steps and improving the ease of use.

Description

Connecting end, pipeline connector and liquid cooling system

[0001] The present application claims priority to the Chinese patent application No. 202410458459.X, filed on April 16, 2024, and entitled "Connecting end, pipeline connector and liquid cooling system", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

For the liquid cooling system applied to servers or other places with high requirements for leak-proof effect, the connector usually includes a male end and a female end, and the male end and the female end respectively include a valve seat and a valve core. When the male end and the female end are disconnected, the valve core needs to close the flow channel in the valve seat to prevent the liquid in the pipeline from leaking. When the male end and the female end are docked and relatively rotated, the valve cores of the male end and the female end can be pushed to rotate to open the flow channel.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0031] Referring to FIG. 1, a connecting end provided by the embodiment of the present application comprises a valve seat 10, a valve core 20 and a locking pin 30. The valve core 20 is rotationally arranged on the valve seat 10 to open and close a flow channel 13 of the valve seat 10. The locking pin 30 is movable in the axial direction of the rotation axis of the valve core 20, and when moved to a first position in the first axial direction 301, the locking pin 30 can prevent the valve core 20 from rotating relative to the valve seat 10. When the locking pin 30 is moved to a second position in the second axial direction 301, the locking pin 30 can rotate to enter a limiting position 101. The movement of the locking pin 30 in the first axial direction 301 refers to the movement of the locking pin 30 towards the valve core 20. The movement of the locking pin 30 in the second axial direction 302 refers to the movement of the locking pin 30 away from the valve core 20. The first position refers to the position of the locking pin 30 when the locking pin 30 prevents the valve core 20 from rotating relative to the valve seat 10. The second position refers to the axial position of the locking pin 30 when the locking pin 30 can be clamped with the valve seat 10. The valve seat 10 is provided with a guide portion 102, and the valve core 20 is provided with a pushing portion 201. When the valve core 20 rotates relative to the valve seat 10, the locking pin 30 moves from the second position to the second axial direction 302 by a predetermined stroke. In the process of movement, the locking pin 30 in the limiting position 101 can be guided to rotate to exit the limiting position 101 due to the action of the guide portion 102. Since the locking pin 30 exits the limiting position 101 in the process of rotating the valve core 20, the user does not need to operate the locking pin 30 again to exit the limiting position 101 after rotating the valve core 20.

[0034] In some embodiments, as shown in FIG. 7 and FIG. 8, the valve seat 10 is provided with a pin hole 14, the side of the pin hole 14 is provided with a sliding groove 141 extending along the axial direction thereof, the side of the locking pin 30 is provided with a blocking rod 36 extending out of the sliding groove 141, the blocking rod 36 is movable relative to the sliding groove 141 to drive the locking pin 30 to move axially in the pin hole 14, wherein a pushing piece 35 can be arranged on one end of the blocking rod 36 extending out of the sliding groove 141, the user can drive the blocking rod 36 by operating the pushing piece 35, or the user can directly act on the blocking rod 36 by fingers to drive the blocking rod 36 to move; the pin hole 14 is provided with a second elastic piece 37 abutting against the end of the locking pin 30 away from the valve core 20 and the pin hole 14 respectively, wherein the pin hole 14 can be designed as a blind hole, and one end of the second elastic piece 37 abuts against the inner end face of the pin hole 14; the side wall of the sliding groove 141 is provided with a first limiting groove 142, the first limiting groove 142 is located at a limiting position 101 for limiting the movement of the locking pin 30 towards the valve core 20, and the side of the first limiting groove 142 away from the valve core 20 and / or the side of the blocking rod 36 away from the valve core 20 is provided with a guide inclined surface 143, the guide inclined surface 143 on the first limiting groove 142 is a guide portion 102, when the locking pin 30 moves to the blocking rod 36 corresponding to the first limiting groove 142 along the axial second direction 302, the blocking rod 36 is rotated to be clamped in the first limiting groove 142, when the valve core 20 rotates relative to the valve seat 10, the locking pin 30 can be driven to move along the axial second direction 302 to a preset stroke by the pushing portion 201, and the blocking rod 36 is rotated to be in the sliding groove 141 under the action of the guide inclined surface 143, and the locking pin 30 is abutted against the valve core 20 under the elastic force of the second elastic piece 37.

[0035] In order to clearly understand the working principle of rotating the valve core 20 to drive the locking pin 30 to exit from the limiting position 101, the following will be described by taking the side of the first limiting groove 142 away from the valve core 20 as an example: the locking pin 30 is in the second position, and the blocking rod 36 is clamped in the first limiting groove 142, the valve core 20 is rotated, the pushing portion on the valve core 20 pushes the locking pin 30 to move away from the valve core 20, the side of the blocking rod 36 away from the valve core 20 contacts the guide inclined surface 143, with the movement of the locking pin 30, the locking pin 30 can be synchronously rotated under the guidance of the guide inclined surface 143, until the blocking rod 36 exits from the first limiting groove 142, at this time the locking pin 30 is abutted against the valve core 20 under the elastic force of the second elastic piece 37, with the continuous rotation of the valve core 20, until the valve core 20 is rotated to a position where the locking pin 30 can be locked.

[0036] In some embodiments, as shown in FIG. 1, FIG. 4 and FIG. 8, the valve seat 10 comprises a valve body 11 and a valve cover 12 connected to the valve body 11 to form a cavity accommodating the valve core 20. For example, a cylindrical segment coaxial with the valve body 11 can be arranged at one end of the valve body 11 towards the valve cover 12, the outer diameter of the cylindrical segment is smaller than the outer diameter of the valve body 11, the valve cover 12 can be capped on the cylindrical segment of the valve body 11, and then the valve cover 12 is fixed on the cylindrical segment of the valve body 11 by fasteners. Specifically, a plurality of fixing holes can be arranged in the circumferential direction of the valve cover 12 and the cylindrical segment, and the fasteners can be inserted into the fixing holes.

[0037] In some embodiments, as shown in FIG. 2, the valve core 20 is provided with a locking hole 21, and the opening of the locking hole 21 towards the locking pin 30 is flared 211, which can be a conical flared 211. The inner side slope of the flared 211 is a pushing part 201. When the locking pin 30 is in the first position, its one end towards the valve core 20 passes through the flared 211 and extends into the locking hole 21. At this time, if the valve core 20 is rotated, the inner wall of the locking hole 21 cannot be contacted with the side wall of the locking pin 30, so the valve core 20 cannot be rotated, and the valve core 20 is in the locked position. When the locking pin 30 is in the second position, its one end towards the valve core 20 is located in the flared 211, for example, the locking pin 30 can be moved in the axial second direction 302 to make the locking pin 30 clamped on the valve seat 10, at the same time, the one end of the locking pin 30 towards the valve core 20 is not completely separated from the locking hole 21, but is retreated into the flared 211. At this time, if the valve core 20 is rotated, the inner side slope of the flared 211 will push the locking pin 30 to move towards the direction away from the valve core 20, and the locking pin 30 will rotate in the process of moving to escape from the limiting position 101.

[0038] In some embodiments, as shown in FIG. 4, the locking hole 21 includes an opening locking hole 22 and a closing locking hole 23, which are distributed along the circumferential direction of the valve core 20. When the valve core 20 is rotated to correspond to the opening locking hole 22 or the closing locking hole 23 with the locking pin 30, the end of the locking pin 30 towards the valve core 20 can extend into the opening locking hole 22 or the closing locking hole 23. When the end of the locking pin 30 towards the valve core 20 extends into the opening locking hole 22, the valve core 20 is fixed relative to the valve seat 10, and the flow passage 13 in the valve seat 10 is in an open state. When the end of the locking pin 30 towards the valve core 20 extends into the closing locking hole 23, the valve core 20 is fixed relative to the valve seat 10, and the flow passage 13 in the valve seat 10 is in a closed state. Taking the valve core 20 of the two connection ends in the closed position and the need to connect the two connection ends as an example, the opposite sides of the valve seat 10 of the two connection ends are provided with connecting parts, and the valve seat 10 is provided with an arc-shaped groove. The connecting parts of the two connection ends can be inserted into the arc-shaped grooves of each other and connected to the valve cores 20 of each other. Then, the locking pin 30 is retreated from the closing locking hole 23. At this time, the two valve seats 10 can be rotated, and the pushing part on the valve core 20 can push the locking pin 30 to move a predetermined stroke into the pin hole 14. At this time, the front end of the locking pin 30 is tightly pressed against the end face of the valve core 20 under the action of the elastic member. When the valve core 20 is rotated to correspond to the opening locking hole 22 with the locking pin 30, the locking pin 30 extends into the opening locking hole 22 under the elastic force of the elastic member to achieve the locking of the valve core 20 relative to the valve seat 10.

[0039] In some embodiments, the end of the locking pin 30 towards the valve core 20 is provided with a pushing slope, for example, a tapered end can be provided at the front end of the locking pin 30, and the slope of the tapered end is the pushing slope. The locking hole 21 can be a circular hole or the opening towards the end of the locking pin 30 is an expanded opening 211 structure, and the pushing part on the valve core 20 is the opening end of the locking hole 21 or the inner slope of the expanded opening 211. When the valve core 20 is rotated relative to the valve seat 10, the pushing part can move the locking pin 30 a predetermined stroke in the axial second direction 302 through the pushing slope. It should be noted that one of the valve core 20 and the locking pin 30 has a slope, which can realize the function of rotating the valve core 20 to drive the locking pin 30 to continue to retract.

[0040] In some embodiments, a protrusion is arranged on the valve core 20 towards the end of the locking pin 30, and a pushing part is arranged on the protrusion. A slope can be arranged on the pushing part and / or the position where the protrusion contacts the locking pin 30. When the valve core 20 rotates, the locking pin 30 can be moved backward by the protrusion, i.e. the locking pin 30 can be moved out of the limiting position 101. Specifically, when the locking pin 30 is completely moved out of the locking hole 21, when the valve core 20 rotates relative to the valve seat 10, the protrusion on the valve core 20 will contact the locking pin 30. With the continuous rotation of the valve core 20, the protrusion will push the locking pin 30 to move in the axial second direction 302 under the action of the pushing part. When the protrusion is separated from the locking pin 30, the front end of the locking pin 30 will abut against the end surface of the valve core 20. After the valve core 20 rotates to the target position, the locking pin 30 will lock the valve core 20 relative to the valve seat 10.

[0041] The embodiment of the present application also provides a pipe connector, as shown in FIG. 3. The pipe connector comprises a male end and a female end which are in abutment and rotatable relative to each other. The male end and the female end are the connecting end provided by any one of the above-mentioned embodiments. The abutment end surface of the valve seat 10 of the connecting end is provided with a connecting part. The valve seat 10 is further provided with an arc-shaped through slot. The valve core 20 is provided with a pushing groove. The connecting part on the male end can extend into the arc-shaped through slot on the female end and be connected to the pushing groove of the valve core 20 in the female end. Meanwhile, the connecting part on the female end can extend into the arc-shaped through slot on the male end and be connected to the pushing groove of the valve core 20 in the male end. When the valve seats 10 of the male end and the female end rotate relative to each other, the valve cores 20 of each other can be pushed to rotate, so as to realize the opening and closing of the flow channel 13. The flow channel 13 on the valve seat 10 is arranged eccentrically relative to the axis of the valve seat 10. A through hole can be arranged on the valve core 20. The diameter of the through hole is preferably the same as the inner diameter of the flow channel 13. When the through hole and the flow channel 13 overlap, the pipe connector is in conduction. When the through hole and the flow channel 13 completely overlap, the pipe connector is in complete conduction. When the through hole is completely staggered with the flow channel 13, the pipe connector is closed.
