[0003] At present, the common water cooling joint mainly adopts plug-in or threaded connection in connecting mode, and the plug-in water cooling joint realizes pipeline connection through plug-in action, and the operation is relatively convenient, and its principle is that elastic sealing elements are arranged in the joint, when the male end is inserted into the female end, the elastic deformation of the sealing element is relied on to realize sealing, and the threaded water cooling joint is connected tightly together through the threaded cooperation of the male end and the female end, and sealing material is arranged at the connecting portion to prevent cooling liquid leakage. However, the existing water cooling joints have certain defects, the plug-in water cooling joint is convenient to operate, but when subjected to external force pulling or vibration, the loosening phenomenon is prone to occur, leading to cooling liquid leakage and affecting the normal operation of the water cooling system, the threaded water cooling joint is relatively firm, but the threads are prone to wear during frequent disassembly and installation, thereby reducing the reliability of the connection, therefore, a water cooling joint with self locking function is needed to solve the above problems. SUMMARY

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a water cooling joint with self locking function, which solves the technical problems of water cooling joint loosening phenomenon and cooling liquid leakage when subjected to external force pulling or vibration.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a water cooling joint with self locking function, comprising: male end pipe, female end pipe, the male end pipe is inserted in the female end pipe to the axial contact of both;

[0006] The locking assembly is movably arranged in the male end connector, and comprises a middle pipe and an inner pipe. The middle pipe is movably arranged in the male end connector, and the middle pipe is sleeved and arranged on the inner pipe. A plurality of accommodating grooves are arranged on the side wall of the middle pipe near the female end connector. The plurality of accommodating grooves are uniformly and circumferentially arranged. A locking bead is arranged in each of the plurality of accommodating grooves. A first defect corresponding to the locking bead is arranged on the inner side wall of the female end connector near the male end connector. When the male end connector and the female end connector are locked as a whole, the middle pipe extends into the female end connector. The inner pipe is used for extruding the locking bead from the accommodating groove into the first defect in the radial direction of the middle pipe. The locking bead is located between the first defect and the accommodating groove.

[0007] The sealing assembly is arranged between the male end connector and the female end connector, and is used for preventing leakage of the cooling liquid.

[0008] The connecting ring is sleeved outside the male end connector and the female end connector, and is threadedly connected with the male end connector and the female end connector.

[0009] Based on the above structure, the water cooling connector with self-locking function is as follows: when the male connector and the female connector need to be connected, first, the male connector is aligned with the female connector, then the male connector is inserted into the female connector until the male connector and the female connector are axially in contact, then the connecting ring is rotated to be screwed with the male connector and the female connector, further reinforcing the connector, and completing the installation operation of the water cooling connector. In this process, the water cooling connector needs to correspond to the flow direction of the cooling liquid, that is, the flow direction of the cooling liquid is from the male connector to the female connector. After the above operation, the male connector and the female connector are connected, and the cooling liquid is injected into the male connector. When a certain pressure is gradually formed in the male connector, the pressure directly acts on the inner tube, pushing the inner tube to generate a force in the radial direction of the middle tube. The middle tube extends into the female connector, and when the middle tube extends to the preset position in the female connector, the groove corresponds to the first defect. Then, the inner tube moves in the axial direction towards the female connector. During the movement of the inner tube, the outer wall of the inner tube will extrude the locking bead in the radial direction of the middle tube, so that the locking bead is extruded out of the groove and clamped into the defect of the inner wall of the female connector. At this time, the locking bead is located between the defect and the groove, and the self-locking function of the male connector and the female connector is realized through the cooperation of the locking bead and the defect. When the locking state needs to be released, the cooling liquid is turned off. Since the middle tube is floatingly arranged in the male connector, the inner tube moves in the axial direction away from the female connector. The extrusion force of the inner tube on the locking bead disappears, the locking bead resets, exits from the defect and returns to the groove. The middle tube moves in the axial direction away from the female connector and resets. Finally, the connecting ring is twisted to separate the male connector and the female connector, and the separation of the two is completed. This self-locking mode relying on the pressure of the cooling liquid to push realizes the self-locking function, which utilizes the power source of the system itself to ensure the locking state and the tight connection between the male connector and the female connector, preventing the connector from loosening during the flow of the cooling liquid and ensuring the stability of the flow of the cooling liquid. The sealing assembly is used to ensure that the cooling liquid does not seep out of the connector during the flow process. Through the fastening of the connecting ring, the connection strength between the male connector and the female connector is further enhanced, the stability of the connector is improved, and stable operation is ensured.

[0010] Further, the water cooling connector with self-locking function in the application is provided with a first protrusion on the inner wall of the female connector, the first protrusion extends along the radial direction of the female connector, and when the male connector and the female connector are connected, the end of the male connector close to the female connector abuts against the first protrusion.

Detailed Implementation

[0026] like Figure 1 , 2 As shown in Figure 4, a water-cooled connector with a self-locking function includes: a male end connector 1 and a female end connector 2, wherein the male end connector 1 is inserted into the female end connector 2 until the two are axially in contact.

[0027] Locking assembly 3 is movably disposed within male end connector 1. Locking assembly 3 includes: a central tube 31 and an inner tube 32. The central tube 31 is floatingly disposed within male end connector 1. The central tube 31 is sleeved on the inner tube 32. A set of receiving grooves 310 is provided on the side wall of the central tube 31 near the female end connector 2. The set of receiving grooves 310 is evenly spaced along the circumference of the central tube 31. Each set of receiving grooves 310 is provided with a locking bead 4. A first notch 20 corresponding to the locking bead 4 is provided on the inner side wall of the female end connector 2 near the male end connector 1. When the male end connector 1 and the female end connector 2 are locked together, the central tube 31 extends into the female end connector 2. The inner tube 32 is used to squeeze the locking bead 4 from the receiving groove 310 into the first notch 20 in the radial direction of the central tube 31. The locking bead 4 is located between the first notch 20 and the receiving groove 310.

[0028] A sealing assembly 5 is disposed between the male end connector 1 and the female end connector 2, and the sealing assembly 5 is used to prevent coolant leakage.

[0029] A connecting ring 12 is sleeved on the outside of the male end connector 1 and the female end connector 2, and the connecting ring 12 is threadedly connected to the male end connector 1 and the female end connector 2.

[0030] Based on the above structure, the principle of the self-locking water-cooling connector is as follows: When connecting the male end connector 1 and the female end connector 2 into one unit, first align the male end connector 1 with the female end connector 2, then insert the male end connector 1 into the female end connector 2 until the male end connector 1 and the female end connector 2 axially abut against each other. Next, rotate the connecting ring 12 to make it threadedly connected with the male end connector 1 and the female end connector 2, further reinforcing the connector and completing the installation operation of the entire water-cooling connector. During this process, the water-cooling connector must correspond to the flow direction of the coolant, that is, the flow direction of the coolant is from the male end connector 1 to the female end connector 2. After completing the above operation, the male end... After the male connector 1 and female connector 2 are connected, coolant is injected into the male connector 1. As a certain pressure gradually forms in the male connector 1, this pressure acts directly on the inner tube 32, pushing the inner tube 32 to exert a force radially on the central tube 31. The central tube 31 extends into the female connector 2. When the central tube 31 reaches the preset position in the female connector 2, the receiving groove 310 corresponds to the first notch 20. Then, the inner tube 32 moves axially towards the female connector 2. During the movement of the inner tube 32, its outer wall will exert a squeezing effect on the locking ball 4 radially on the central tube 31, causing the locking ball 4 to be squeezed out of the receiving groove 310. The male connector 1 and female connector 2 are locked into the first notch 20 on the inner side wall of the female connector 2. At this time, the locking ball 4 is located between the first notch 20 and the receiving groove 310. Through the cooperation of the locking ball 4 and the first notch 20, the male connector 1 and female connector 2 achieve the self-locking function. When it is necessary to release the locking state, the coolant is turned off. Since the central tube 31 is floating in the male connector 1, the inner tube 32 moves axially away from the female connector 2. The squeezing force of the inner tube 32 on the locking ball 4 disappears, the locking ball 4 resets, exits from the first notch 20 and returns to the receiving groove 310, and the central tube 31 moves axially away from the female connector 2. Finally, tighten the connecting ring 12 to separate the male connector 1 from the female connector 2, completing the separation. This self-locking method, driven by coolant pressure, utilizes the system's own power source to ensure the locked state and a tight connection between the male connector 1 and the female connector 2, preventing loosening of the joint during coolant flow and ensuring the stability of coolant flow. The sealing component 5 ensures that coolant does not leak from the joint during flow. The tightening of the connecting ring 12 further enhances the connection strength between the male connector 1 and the female connector 2, improving the stability of the joint and ensuring stable operation. There are eight receiving slots 310, and correspondingly, eight locking beads 4.

[0031] In this embodiment, a first protrusion 21 is provided on the inner sidewall of the female end connector 2. The first protrusion 21 extends radially along the female end connector 2. When the male end connector 1 and the female end connector 2 are connected, the end of the male end connector 1 near the female end connector 2 abuts against the first protrusion 21. During the process of inserting the male end connector 1 into the female end connector 2, the operator can determine whether the male end connector 1 has been inserted into the appropriate position by the end of the male end connector 1 abutting against the first protrusion 21, ensuring that the male end connector 1 and the female end connector 2 are accurately aligned in the axial direction, so that the receiving groove 310 and the first notch 20 can accurately correspond, and preventing the male end connector 1 from being over-inserted into the female end connector 2, avoiding damage to the internal components of the female end connector 2 due to excessive insertion.

[0032] like Figure 3 As shown, in this embodiment, the depth of the receiving groove 310 is greater than the radius of the locking bead 4 and less than the diameter of the locking bead 4. The opening of the receiving groove 310 near the male end connector 1 is smaller than the diameter of the locking bead 4. The greater depth of the receiving groove 310 ensures sufficient space for the locking bead 4 to move within the receiving groove 310. This allows the locking bead 4 to be smoothly squeezed out of the receiving groove 310 and inserted into the first notch 20 on the inner wall of the female end connector 2 during the docking process of the male end connector 1 and the female end connector 2, thus achieving a self-locking function between the male end connector 1 and the female end connector 2. The smaller depth of the receiving groove 310 prevents the locking bead 4 from completely sinking into the receiving groove 310. A portion of the lock ball will always protrude from the 310. When the inner tube 32 presses against it, the locking ball 4 can smoothly engage with the first notch 20. At the same time, when it is necessary to release the locking state, the locking ball 4 can also smoothly exit from the first notch 20 and return to the 310 under the reset action of the central tube 31 and the inner tube 32. The opening on the side of the 310 near the male end of the connector 1 is smaller than the diameter of the locking ball 4. This design is to prevent the locking ball 4 from coming out of the opening on the side of the 310 near the male end of the connector 1, thereby causing the self-locking component to fail.

[0033] In this embodiment, the inner tube 32 has a second notch 320 near the female end connector 2. The second notch 320 extends circumferentially along the inner tube 32 and has an inclined surface inside. The inclined surface is arranged radially outward along the inner tube 32. When the inner tube 32 moves axially toward the female end connector 2, the inclined surface inside the second notch 320 contacts the locking bead 4. Since the inclined surface is arranged radially outward along the inner tube 32, the axial movement of the inner tube 32 will cause the locking bead 4 to move radially in the central tube 31, so that the locking bead 4 can be squeezed out of the receiving groove 310 and inserted into the first notch 20 on the inner sidewall of the female end connector 2, thereby realizing the self-locking function of the male end connector 1 and the female end connector 2.

[0034] In this embodiment, an extension 11 extends radially on the inner wall of the male end connector 1, and a second protrusion 311 extends radially on the outer wall of the central tube 31. A first elastic member 6 is sleeved on the outer side of the central tube 31, and the two ends of the first elastic member 6 abut against the extension 11 and the second protrusion 311 in the axial direction of the male end connector 1, respectively. The extension 11 and the second protrusion 311, in conjunction with the first elastic element 6, allow the central tube 31 to float within the male end connector 1. When coolant is injected into the male end connector 1, creating pressure that pushes the inner tube 32, the inner tube 32 applies pressure to the locking ball 4, causing the locking ball 4 to engage with the first notch 20 and lock. When the coolant is turned off and the pressure disappears, the first elastic element 6 returns to its elastic deformation, and the resulting elastic force pushes the central tube 31 axially away from the female end connector 2 to reset. Simultaneously, the pressure of the inner tube 32 on the locking ball 4 disappears, and the locking ball 4, driven by the reset of the central tube 31, exits from the first notch 20 and returns to the receiving groove 310, completing the unlocking process. The first elastic element 6 is a spring.

[0035] In this embodiment, a mounting cover 7 is provided on the inner wall of the male end connector 1 away from the female end connector 2. The mounting cover 7 is threadedly connected to the male end connector 1, and the end of the central tube 31 away from the female end connector 2 axially abuts against the mounting cover 7. The mounting cover 7 and the male end connector 1 are connected by threads to facilitate the assembly and disassembly of the internal components of the male end connector 1. When it is necessary to maintain or repair the internal components of the male end connector 1, simply unscrew the mounting cover 7 to easily remove the central tube 31 and other components for inspection, replacement or repair.

[0036] In this embodiment, an annular receiving cavity 312 is provided on the inner wall of the end of the central tube 31 away from the female end connector 2. A second elastic element 8 is provided in the annular receiving cavity 312. The second elastic element 8 is sleeved on the outside of the inner tube 32. An annular cover 9 is provided at the end of the inner tube 32 away from the female end connector 2. The annular cover 9 extends radially out of the outer wall of the inner tube 32. A through hole 90 is provided on the annular cover 9. The two ends of the second elastic element 8 respectively abut against the annular cover 9 and the side wall of the annular receiving cavity 312 in the axial direction of the male end connector 1. When the coolant is shut off and the pressure disappears, the restoring force provided by the second elastic element 8 ensures that the squeezing force of the inner tube 32 on the locking ball 4 disappears in time, allowing the locking ball 4 to smoothly exit from the first notch 20 of the female end connector 2 and return to the receiving groove 310 of the central tube 31, thereby unlocking the male end connector 1 and the female end connector 2, ensuring that the locking to unlocking cycle of the entire water-cooled connector can proceed smoothly; the annular cover 9 is used to ensure that there is sufficient pressure in the male end connector 1 to push the central tube 31 and the inner tube 32 to move axially; the through hole 90 provides a flow channel for the coolant. The second elastic element 8 is a spring.

[0037] In this embodiment, the sealing assembly 5 includes a first annular seal 51 and a second annular seal 52. The first annular seal 51 is disposed between the axial contact surfaces of the male end connector 1 and the female end connector 2, and the second annular seal 52 is disposed between the radial contact surfaces of the male end connector 1 and the female end connector 2. The first annular seal 51 is used for axial sealing between the male end connector 1 and the female end connector 2, and the second annular seal 52 is used for radial sealing between the male end connector 1 and the female end connector 2. The two seals work together to ensure that the coolant does not leak. Both the first annular seal 51 and the second annular seal 52 are O-rings.

[0038] In this embodiment, the sealing assembly 5 further includes a set of third annular seals 53, which are spaced apart along the axial direction of the male end connector 1 on the inner sidewalls of the extension 11 and the first protrusion 21. The set of third annular seals 53 ensures that when the male end connector 1 and the female end connector 2 are self-locking, no leakage occurs between the central tube 31 and the male end connector 1 and the female end connector 2. The set of third annular seals 53 consists of three elements: one on the inner sidewall of the extension 11 and two on the inner sidewall of the first protrusion 21, spaced apart along the axial direction of the female end connector 2. The third annular seals 53 are O-rings.
