Description

Technical Field

[0001] The present invention relates to the technical field of rotary joints, in particular to a rotary joint for a server liquid cooling pipe. Background Art

[0002] As server heat dissipation becomes increasingly challenging, traditional air cooling struggles to meet the cooling needs of high-density server racks. Liquid cooling technology circulates coolant within the server, removing heat and improving heat dissipation efficiency. Rotary joints, as key components connecting coolant pipes, are crucial for ensuring efficient and stable operation of cooling systems.

[0003] When connecting and disconnecting traditional connectors, an additional handle needs to be rotated to open or close the ball valve. The operation is relatively cumbersome and inefficient, which increases the complexity and time cost of the operation, making the operation of locking and opening the ball valve time-consuming and labor-intensive.

[0004] Patent CN207921370U discloses a quick self-locking connector with safety measures. The above patent maximizes the flow rate, enables the valve core to open a larger flow hole, increases the flow rate, prevents the quick self-locking connector with safety measures from opening accidentally, and further improves the overall safety.

[0005] The above patent uses a special ball valve design to ensure the safety of the connector against disengagement during use, solving the problem of the connector having a single function and a slow flow rate. However, there is still room for improvement in the rotation of the ball valve in the valve body and the opening or closing of the valve body. The present application connects the two connectors by rotation, achieving preliminary locking and opening of the ball valve at the same time, solving the problem of still needing to open the ball valve by rotating the handle after the two connectors are rotated into place.

A square bevel gear 7 is provided, and the arcuate tooth block 11 matches the square bevel gear 7. The arcuate tooth block 11 is used for the square bevel gear 7 with another rotary joint. The square bevel gear 7 is fixedly mounted on the outer wall of the intermediate bolt 5. The side wall of the intermediate bolt 5 is fixedly connected with a metal ball valve 6. The intermediate bolt 5 is used to drive the metal ball valve 6. The outer wall of the valve body shell 1 is provided with a slot mechanism, and the slot mechanism includes: a common slot 15 and a reserved slot 16. The reserved slot 16 is used to fit the toothed buckle 10 of another rotary joint, and the common slot 15 is used to fit the smooth buckle 9 of another rotary joint.

[0040] The outer wall of the valve body shell 1 is provided with a reserved tooth groove 17, which is communicated with the reserved card groove 16, and the reserved tooth groove 17 is used to fit the arc-shaped tooth block 11 of another rotary joint; the valve body shell 1 is equidistantly provided with a clamping block 36, and the side wall of the clamping block 36 is fixedly connected to the compression spring 37, and the side wall of the compression spring 37 is fixedly connected to the valve body shell 1, and the inner wall of the valve body shell 1 is provided with a through groove 35, and the through groove 35 is arranged on the outside of the arc-shaped tooth block 11, and the outer wall of the valve body shell 1 is provided with a sealing gasket 12.

[0041] Furthermore, when connecting two rotary joints, align their two ends, insert the three-claw buckle mechanism of one of the rotary joints into the empty slot mechanism of the other rotary joint, that is, insert the two smooth buckles 9 of one of the rotary joints into the two ordinary slots 15 of the other rotary joint, and insert a toothed buckle 10 of one of the rotary joints into a reserved slot 16 of the other rotary joint. In the process of inserting the toothed buckle 10, align the reserved tooth groove 17 of one of the rotary joints with the arc-shaped tooth block 11 of the other rotary joint, so that the arc-shaped tooth block 11 is inserted into the reserved tooth groove 17; after the two rotary joints are docked with each other, rotate one of the rotary joints or rotate the two rotary joints in opposite directions, so that the three-claw buckle mechanism of one rotary joint gradually rotates inside the other rotary joint to achieve preliminary locking, so that the toothed buckle of one of the rotary joints The buckle 10 gradually approaches the square bevel gear 7. When the arc-shaped tooth block 11 contacts the part of the square bevel gear 7 at the through-port groove 35, the arc-shaped tooth block 11 meshes with the arc-shaped tooth block 11, and the toothed buckle 10 drives the arc-shaped tooth block 11, and the toothed buckle 10 drives the toothed buckle 10 to rotate the square bevel gear 7, and the square bevel gear 7 drives the middle bolt 5 to rotate, and the middle bolt 5 drives the metal ball valve 6 to rotate, thereby opening the metal ball valve 6, even if the through-port of the metal ball valve 6 is opposite to the through-port of the metal ball valve 6, thereby opening the passage between the two pipe joints 2; when closing the metal ball valve 6, it is only necessary to rotate the three-claw buckle mechanism in the opposite direction to rotate the toothed buckle 10 toward the reserved slot 16, so that the arc-shaped tooth block 11 is re-engaged with the square bevel gear 7, thereby driving the square bevel gear 7, the middle bolt 5, and the metal ball valve 6 again, so that the metal ball valve 6 is reset, closing the passage between the two pipe joints 2, and realizing the closure of the metal ball valve 6;

[0042] The three-claw buckle mechanism of one rotary joint is inserted into the other rotary joint. After the rotation is aligned, the valve body shell 1 contacts the smooth buckle 9 and the toothed buckle 10 to achieve preliminary locking. At the same time, during the locking process of the rotation alignment, the toothed buckle 10 and the toothed buckle 10 drive the square bevel gear 7, the middle bolt 5, and the metal ball valve 6, thereby synchronously opening the ball valve device in the joint, realizing the synchronization of preliminary locking and ball valve opening. Only one step is required, and no additional ball valve opening operation is required. The three-claw buckle mechanism is inserted into the empty slot mechanism and locked after rotation, thereby ensuring a stable connection of the liquid cooling pipeline. Only one rotation is required to complete the preliminary locking and ball valve opening at the same time. The operation is simple and quick, and compared with the finger force of the handle to drive the ball valve, the arm and wrist force method of directly rotating the rotary joint to open the ball valve is more labor-saving, which improves the work efficiency of installation and maintenance; in the rotation process of the three-claw buckle mechanism, the smooth buckle 9 and the toothed buckle 10 are respectively in contact with the clamping block 36 on the valve body shell 1, thereby driving the clamping block 36 to squeeze the compression spring 37. Under the action of the elastic force of the compression spring 37, the clamping block 36 squeezes the three-claw buckle mechanism, so that the sealing gaskets 12 on the two valve body shells 1 are squeezed against each other, thereby making the connection between the two rotary joints tighter, and at the same time, ensuring the sealing effect and ensuring that the coolant is leak-free during the transmission process.

[0043] See also Figure 1 、 Figure 3 、 Figure 5 and Figure 6 , an embodiment provided by the present invention: a rotary joint for a server liquid cooling pipe, a valve body shell 1 is provided with a smooth buckle 9 and a toothed buckle 10, a general card slot 15 and a reserved card slot 16 are opened on the valve body shell 1, the valve body shell 1 is provided with a press-locking component, the press-locking component is used to lock the metal ball valve 6; the valve body shell 1 is movably sleeved on the outer wall of the locking slider 19, the locking slider 19 is used to resist and fix the smooth buckle 9, the outer wall of the locking slider 19 is movably sleeved with a first spring 20, and the side wall of the valve body shell 1 is fixedly connected to the first spring Spring 20, the side wall of the first spring 20 is fixedly connected to a first resisting block 21, the first resisting block 21 is used to drive the first spring 20, the side wall of the first resisting block 21 is fixedly connected to a resisting block 22, the outer wall of the first resisting block 21 is movably sleeved with a locking body 13, the locking body 13 is movably sleeved on the outer wall of the pressing slider 18, the pressing slider 18 is used for the operator's press and lock operation, the outer wall of the pressing slider 18 is provided with a first-step slot 23, the outer wall of the pressing slider 18 is provided with a second-step slot 25, and the resisting block 22 is in contact with the pressing slider 18;

[0044] A sliding groove 24 is provided on the outer wall of the second-stage slot 25, and the sliding groove 24 is communicated with the first-stage slot 23. A reset block 26 is fixedly connected to the side wall of the pressing slider 18. The outer wall of the reset block 26 is movably covered with a locking body 13, and a second spring 27 is provided in the locking body 13. A second resistance block 28 is fixedly installed on the outer wall of the reset block 26. The second resistance block 28 is used to drive the second spring 27. The second spring 27 contacts the second resistance block 28. The outer wall of the reset block 26 is movably covered with the second spring 27, and the outer wall of the second resistance block 28 is movably covered with the locking body 13.

[0045] Further, the smooth buckle 9 and the toothed buckle 10 of one of the rotating joints are respectively inserted into the ordinary card slot 15 and the reserved card slot 16 of the other rotating joint. After rotating into place, the preliminary locking is achieved. By pushing the pressing slider 18 on the locking body 13, the pressing slider 18 drives the resisting card block 22 to move, and the resisting card block 22 drives the first resisting block 21 and the locking slider 19 to move. The first resisting block 21 compresses the first spring 20, and the resisting card block 22 moves from the second-stage card slot 25 of the pressing slider 18 to the first-stage card slot 23. Under the action of the first-stage card slot 23, the pressing slider 18 drives The contact block 22, the first contact block 21, and the locking slider 19 push out the locking slider 19, so that the locking slider 19 is clamped on one of the smooth buckles 9 to achieve further locking. Double locking is achieved by the three-claw buckle mechanism and the locking slider 19. When the contact block 22 is in the first-stage slot 23, the pressing slider 18 abuts against the contact block 22 to prevent the contact block 22 from resetting and thus releasing the locked state. During the process of the contact block 22 moving to the first-stage slot 23, the pressing slider 18 drives the reset block 26 to move, and the reset block 26 drives the second contact block 28 to compress the second spring 27.

[0046] When the second interference block 28 is released from locking the smooth buckle 9, the pressing slider 18 is rotated, and the pressing slider 18 drives the sliding groove 24 to rotate. When the sliding groove 24 rotates to the position of the interference block 22, the interference block 22 no longer interferes with the pressing slider 18. Under the action of the second spring 27, the second spring 27 is restored from the compressed state to the original state. The second spring 27 drives the second interference block 28 and the reset block 26 to reset. The reset block 26 drives the pressing slider 18 to move, and the interference block 22 moves from the first-stage slot 23. After passing through the sliding groove 24, it returns to the second-stage clamping groove 25. Under the action of the first spring 20, the first spring 20 drives the first contact block 21, the contact clamping block 22, and the locking slider 19 to reset, so that the locking slider 19 no longer blocks the locking slider 19, thereby releasing the locking state. At this time, the two rotary joints can be rotated and separated; the locking state of the joint is judged by the reset block 26. When part of the reset block 26 of the locking body 13 protrudes, the joint is in the locked state. When the reset block 26 on the locking body 13 does not protrude, the joint is not locked.

[0047] See also Figure 1 、 Figure 5 and Figure 7 , an embodiment of the present invention provides: a rotary joint for a server liquid cooling pipe, a valve body shell 1 is provided with a smooth buckle 9 and a toothed buckle 10, a general card slot 15 and a reserved card slot 16 are opened on the valve body shell 1, a pressing slider 18 and a locking slider 19 are provided in the locking body 13, and an auxiliary positioning component is provided on the three-claw buckle mechanism, and the auxiliary positioning component performs magnetic auxiliary positioning when the three-claw buckle mechanism is inserted into the empty slot mechanism; positioning magnets 40 are fixedly installed on the smooth buckle 9 and the toothed buckle 10 respectively, and pre-positioning magnetic blocks 38 are fixedly installed on the outer wall of the valve body shell 1 at equal distances. When the buckle mechanism is inserted into the empty slot mechanism, the pre-positioning magnetic block 38 attracts the positioning magnet 40 for initial positioning. Pre-positioning magnetic blocks 38 are respectively provided in the ordinary card slot 15 and the reserved card slot 16. Auxiliary magnetic blocks 39 are fixedly installed on the outer wall of the valve body shell 1 at equal distances. When the three-claw buckle mechanism is rotated into place, the auxiliary magnetic block 39 attracts the positioning magnet 40 for auxiliary positioning. An annular groove 41 is provided on the outer wall of the valve body shell 1. The annular groove 41 is communicated with the ordinary card slot 15, and the reserved card slot 16 is communicated with the annular groove 41. The annular groove 41 provides a channel for the rotation of the three-claw buckle mechanism, and the auxiliary magnetic block 39 is arranged in the annular groove 41.

[0048] Furthermore, in the process of inserting the three-claw buckle mechanism of one rotary joint into the empty slot mechanism of the other rotary joint, align the smooth buckle 9 and the toothed buckle 10 with the ordinary slot 15 and the reserved slot 16 respectively, and insert the smooth buckle 9 and the toothed buckle 10 into the ordinary slot 15 and the reserved slot 16 respectively. As the smooth buckle 9 and the toothed buckle 10 continue to move into the ordinary slot 15 and the reserved slot 16, the positioning magnets 40 on the smooth buckle 9 and the toothed buckle 10 gradually approach the pre-positioning magnetic block 38, so that the pre-positioning magnetic block 38 absorbs the positioning magnet 40, and the initial positioning of the three-claw buckle mechanism is achieved. The operator judges the insertion status of the three-claw buckle mechanism by feeling the force of the pre-positioning magnetic block 38 to absorb the positioning magnet 40, and the pre-positioning magnetic block 38 absorbs the positioning magnet 40 to make the positioning magnet 40 to a certain extent. Drive the three-claw buckle mechanism to move into the empty slot mechanism; when the three-claw buckle mechanism is rotated, when the three-claw buckle mechanism gradually rotates to the locking position, the positioning magnets 40 of the smooth buckle 9 and the toothed buckle 10 gradually approach the auxiliary magnetic block 39, so that the auxiliary magnetic block 39 absorbs the positioning magnet 40. When the three-claw buckle mechanism is rotated, the screw-in status of the three-claw buckle mechanism can be determined by the change in the sensing force, avoiding damage to the three-claw buckle mechanism caused by excessive rotation, and the initial fixation of the three-claw buckle mechanism is achieved by the auxiliary magnetic block 39. When the locking slider 19 is engaged with the locking smooth buckle 9, the three-claw buckle mechanism is prevented from rotating in the opposite direction due to operational errors by the operator when pushing the pressing slider 18, resulting in the locking slider 19 being unable to engage with the locking smooth buckle 9, thereby requiring readjustment, reducing the connection efficiency.

[0049] See also Figure 1 、 Figure 5 and Figure 6 , an embodiment of the present invention provides: a rotary joint for a server liquid cooling pipe, a valve body shell 1 is provided with a three-claw buckle mechanism, the three-claw buckle mechanism includes: a smooth buckle 9 and a toothed buckle 10, a slot mechanism is provided on the valve body shell 1, a pressing slider 18 and a locking slider 19 are provided in the locking body 13; the locking body 13 is provided with an anti-accidental touch component, which is used to prevent the operator from accidentally touching the pressing slider 18 when connecting the rotary joint; the side walls of the locking body 13 are symmetrically fixedly connected with magnetic The suction piece 30, the side wall of the magnetic piece 30 is provided with a magnetic block 29, the magnetic piece 30 is used to adsorb the magnetic block 29, the outer wall of the magnetic block 29 is fixedly connected with the anti-touch block 14, the attached magnetic block 29 can be inserted into the locking body 13, the anti-touch block 14 is detachably connected to the side wall of the locking body 13, the outer wall of the magnetic block 29 is movably covered with the outer wall of the anti-touch block 14, the side wall of the anti-touch block 14 is provided with an insertion groove 31, the insertion groove 31 is movably covered on the outer wall of the pressing slider 18, and the locking body 13 provides protection for the pressing slider 18.

[0050] Furthermore, the three-claw buckle mechanism is inserted into the empty slot mechanism, and before rotating the three-claw buckle mechanism, the insertion groove 31 of the anti-touch block 14 is aligned with the pressing slider 18, and the anti-touch block 14 is moved to insert the pressing slider 18 into the groove 31, and the magnetic block 29 is aligned with the magnetic sheet 30, so that the magnetic block 29 is inserted into the corresponding groove, and the magnetic sheet 30 adsorbs the magnetic block 29, thereby installing and connecting the anti-touch block 14 to the locking body 13, and the pressing slider 18 is protected by the anti-touch block 14 to prevent the operator from accidentally touching the pressing slider 18, and the magnetic block 29 and the magnetic sheet 30 are aligned. The adsorption effect between the suction pieces 30 prevents the anti-touch block 14 from separating from the locking body 13 under the action of external force, thereby preventing the operator from accidentally touching the pressing slider 18 when rotating the three-claw buckle mechanism, causing the locking slider 19 to perform the locking operation in advance, thereby interfering with the smooth buckle 9, resulting in the rotating three-claw buckle mechanism being unable to rotate to the expected position, thereby causing the ball valve to be unable to fully open, making the locking mechanism of the rotary joint invalid, resulting in a loose connection of the rotary joint, and a risk of leakage, affecting the heat dissipation efficiency of the liquid cooling system, and may cause overheating and damage to the server.

[0051] See also Figure 1 、 Figure 2 and Figure 6, an embodiment of the present invention provides: a rotary joint for a server liquid cooling pipe, a valve body shell 1 is provided with a three-claw buckle mechanism, a valve body shell 1 is provided with an empty slot mechanism, a pressing slider 18 and a locking slider 19 are provided in the locking body 13, and the side wall of the anti-contact block 14 is provided with a clamping groove 33, the inner diameter of the clamping groove 33 is the same as the inner diameter of the insertion groove 31, the pressing slider 18 can be inserted into the clamping groove 33, and the anti-contact block 14 is symmetrically provided with clamping blocks 34, the clamping blocks 34 are in the clamping groove 33, and the outer wall of the pressing slider 18 is symmetrically provided with docking grooves 32, the size of the docking groove 32 is the same as the size of the clamping block 34, and the clamping block 34 can be inserted into the docking groove 32.

[0052] Furthermore, when the three-claw buckle mechanism is inserted into the empty slot mechanism and the three-claw buckle mechanism is rotated, the anti-touch block 14 protects the pressing slider 18 to avoid accidental touch by the operator. After the three-claw buckle mechanism is rotated into place, an external force is applied to the anti-touch block 14 to separate the anti-touch block 14 and the locking body 13, pushing the pressing slider 18. The pressing slider 18 drives the locking slider 19, so that the locking slider 19 performs a locking operation to lock the three-claw buckle mechanism. When the locking state of the three-claw buckle mechanism is released, the anti-touch block 14 can be operated to align the engaging groove 33 of the anti-touch block 14 with the pressing slider 18, and align the docking groove 32 with the engaging block 34. The pressing slider 18 is inserted into the engaging groove 33 and the engaging block 34 is inserted into the docking groove 32. At this time, the anti-touch block 14 can be rotated, and the anti-touch block 14 drives the engaging block 34 to rotate, and the engaging block 34 drives the pressing slider 18 to rotate, thereby resetting the locking slider 19 and releasing the locking state of the three-claw buckle mechanism. By providing the engaging groove 33 and the engaging block 34 on the anti-touch block 14, the anti-touch block 14 becomes a tool that can drive the pressing slider 18 to rotate, thereby avoiding the pressing slider 18 surface being too smooth or the pressing slider 18 being too small, which makes it difficult for the operator to operate, and the pressing slider 18 can be rotated to improve the convenience of operation.

[0053] See also Figure 1 、 Figure 5 and Figure 8, an embodiment provided by the present invention: a rotary joint for a server liquid cooling pipe, a valve body shell 1 is provided with a three-claw buckle mechanism, the inner wall of the valve body shell 1 is provided with a first plug-in groove 8, the first plug-in groove 8 is communicated with the annular groove 41, the inner wall of the valve body shell 1 is provided with a translation groove 43, the translation groove 43 is movably sleeved on the outer wall of the smooth buckle 9, the translation groove 43 is communicated with the first plug-in groove 8, the outer wall of the smooth buckle 9 is fixedly connected with a limiting block 4, the side wall of the translation groove 43 is provided with a second plug-in groove 42, the outer wall of the limiting block 4 is movably sleeved with a second plug-in groove 42, the second plug-in groove 42 is communicated with the first plug-in groove 8, the smooth A positioning slot 47 is provided on the side wall of the clip 9, and a positioning column 46 is fixedly connected to the side wall of the valve body shell 1 at equal intervals, and the positioning slot 47 is movably mounted on the outer wall of the positioning column 46; the inner wall of the valve body shell 1 is provided with a push-in groove 48 at equal intervals, and the push-in groove 48 is movably mounted on the outer wall of the push-in plate 45, and a push-in block 44 is fixedly connected to the outer wall of the push-in plate 45, and the push-in block 44 is located in the annular groove 41, and the push-in block 44 is in contact with the limiting block 4. The smooth clip 9 has the same structure as the toothed clip 10, and the connection method between the toothed clip 10 and the valve body shell 1 is the same as the connection method between the toothed clip 10 and the smooth clip 9.

[0054] Furthermore, during the transportation of the rotary joint, the three-claw buckle mechanism on the valve body shell 1 may collide with an object, causing the three-claw buckle mechanism to be deformed or damaged. At the same time, as the rotary joint is used for an increasing period of time, the wear of the three-claw buckle mechanism gradually increases. At this time, the push-in block 44 is moved vertically, and the push-in block 44 drives the push-in plate 45 to move out of the push-in groove 48, and the smooth buckle 9 is moved horizontally. The smooth buckle 9 moves in the translation groove 43, so that the positioning pin 46 gradually moves out of the positioning slot 47, so that the smooth buckle 9 moves out of the translation groove 43, and the limiting block 4 moves out of the second plug-in slot 42, so that the limiting block 4 moves into the first plug-in slot 8. At this time, the smooth buckle 9 can be moved vertically to move the smooth buckle 9 and the limiting block 4 out of the first plug-in slot 8, thereby separating the smooth buckle 9 and the valve body shell 1; insert the intact smooth buckle 9 into the first plug-in slot 8, and move the smooth buckle 9 horizontally to move the limiting block 4 into the second plug-in slot 42, The smooth buckle 9 moves into the translation groove 43, and the positioning pin 46 is inserted into the positioning slot 47. Since the width of the second plug-in slot 42 is longer than the translation groove 43, the second plug-in slot 42 and the translation groove 43 form a T-shaped structure. The second plug-in slot 42 matches the limiting block 4, and the smooth buckle 9 matches the translation groove 43, so that the second plug-in slot 42 limits the limiting block 4, preventing the limiting block 4 and the smooth buckle 9 from moving in the vertical direction, and the pushing block 44 is reinstalled into the annular groove 41, so that the pushing plate 45 moves into the pushing groove 48, and the pushing block 44 resists the smooth buckle 9, preventing the smooth buckle 9 from moving in the horizontal direction; the same steps as above can be used to replace the toothed buckle 10, and by quickly replacing the three-claw buckle mechanism, the three-claw buckle mechanism of different materials can be replaced, thereby adapting to the ball valve requirements of different flow or pressure, extending the life of the joint, reducing maintenance costs, and reducing the cost of replacing the entire rotary joint.

[0055] Working principle: When connecting two connectors, insert the three-claw buckle mechanism of one connector into the empty slot mechanism of the other connector. The pre-positioning magnet 38 attracts the positioning magnet 40 for pre-positioning. Rotate the connector toothed buckle 10 and the arc-shaped tooth block 11 to drive the square bevel gear 7, the middle bolt 5, and the metal ball valve 6 to open the metal ball valve 6.

[0056] After the three-claw buckle mechanism rotates into place, the auxiliary magnetic block 39 attracts the positioning magnet 40 to achieve the initial fixation of the three-claw buckle mechanism, pushing the pressing slider 18, which drives the contact block 22, the first contact block 21, and the locking slider 19 to move. The contact block 22 moves from the second-stage slot 25 to the first-stage slot 23, pushing out the locking slider 19 to achieve the locking of the connector;

[0057] When the locking state is released, the anti-contact block 14 on the locking body 13 is removed, the engaging groove 33 is aligned with the pressing slider 18, the pressing slider 18 and the engaging block 34 are respectively inserted into the engaging groove 33 and the docking groove 32, and the anti-contact block 14 is rotated. The anti-contact block 14 drives the engaging block 34 and the pressing slider 18 to rotate, and the contact block 22 moves back to the second-stage engaging groove 25 through the sliding groove 24, and the locking slider 19 is reset.
