[0026] The following is only a preferred embodiment of the present application, and does not limit the protection scope of the present application.

[0027] A liquid cooling quick plug device for compensating plug precision, as shown in Figures 1 to 4 Fig. 1, comprising a shell, a floating water nozzle 4 and two elastic floating assemblies 5 are arranged in the shell, the floating water nozzle 4 is arranged in the shell, the two ends of the floating water nozzle 4 respectively extend out of the end of the shell, the outer diameter of the floating water nozzle 4 is smaller than the inner diameter of the shell, the floating water nozzle 4 has a floating gap with the shell, the middle part of the floating water nozzle 4 is provided with a reset baffle 41, the two elastic floating assemblies 5 are respectively sleeved on the floating water nozzle 4, the two elastic floating assemblies 5 are respectively arranged symmetrically on the two sides of the reset baffle 41, the first end of the two elastic floating assemblies 5 respectively abuts against the inner wall of the shell, the second end of the two elastic floating assemblies 5 is respectively provided with a conical elastic reset inclined surface 521 which expands towards the reset baffle 41, the two sides of the reset baffle 41 respectively abut against the elastic reset inclined surface 521 of the two elastic floating assemblies 5.

[0028] The traditional liquid cooling quick plug device adopts rigid connection, which is not only difficult to install, but also easy to damage the seal under vibration and connection stress, resulting in liquid leakage, poor reliability and stability, while the present application connects the shell and the floating water nozzle 4 through the two elastic floating assemblies 5, the floating gap gives the floating water nozzle 4 a displacement stroke in three-dimensional space, so that the floating water nozzle 4 elastically floats in the shell, when the plug is connected with the floating water nozzle 4, the floating water nozzle 4 can displace in the radial and axial directions to compensate the connection deviation between the plug and the floating water nozzle 4, reducing the plug precision, when there is a positional deviation, it can automatically adapt and ensure the precise butt joint of the liquid cooling pipeline, avoiding the problems of connection difficulty, seal damage and cooling liquid leakage caused by installation error, effectively improving the operation stability and efficiency of the liquid cooling system; through the elasticity of the two elastic floating assemblies 5, the floating water nozzle 4 is reset in the axial direction, and under the action of the elastic reset inclined surface 521, the floating water nozzle 4 is reset in the radial direction, so that the floating water nozzle 4 can automatically recover to the center position after deviation, thereby realizing compensation for the rotation deviation around the shaft, the structure is simple and the cost is low; after the plug is connected with the floating water nozzle 4, it is automatically reset, so that the floating water nozzle 4 is in the maximum floatable position, to improve the performance of resisting vibration or connection stress, and after the plug is separated from the floating water nozzle 4, it is automatically reset, thereby facilitating the next connection and improving the connection success rate.

[0029] Specifically, the elastic floating assembly 5 includes a spring 51 and a floating push plate 52. The floating push plate 52 is a ring-shaped floating push plate 52. Both the spring 51 and the floating push plate 52 are sleeved on the floating water nozzle 4. One end of the spring 51 abuts against the inner wall of the outer shell, and the other end abuts against the floating push plate 52. The elastic reset inclined surface 521 is provided on the side of the floating push plate 52 facing the reset baffle 41. The floating push plate 52 and the reset baffle 41 abut against each other. The elastic floating assembly 5 is given elasticity by spring 51. Spring 51 is a cylindrical spring, which has a simple structure and low cost. Spring 51 can not only give the floating water nozzle 4 elastic force in the axial direction, but also give the floating water nozzle 4 elastic force on the axial clamp. When the floating water nozzle 4 has an angular deviation, spring 51 can also compensate for and reset the angular deviation. Two floating push plates 52 clamp and fix the reset baffle 41. When resetting, the two springs 51 respectively give the two floating push plates 52 pressure to move relative to each other, so that the two floating push plates 52 move towards each other. Under the action of the elastic reset inclined surface 521, the reset baffle 41 moves along the elastic reset inclined surface 521 toward the axis, thereby resetting in the radial direction. The structure is simple and the cost is low.

[0030] Specifically, the inner diameter of the floating push plate 52 is smaller than the outer diameter of the reset baffle 41. This structure allows the floating push plate 52 to limit the reset baffle 41 in the axial direction, ensuring that the reset baffle 41 is clamped between the two floating push plates 52, preventing the floating water nozzle 4 from falling off when plugging or unplugging the plug, and improving reliability and stability.

[0031] Specifically, the outer edges of the reset baffle 41 are respectively provided with conical floating reset ramps 411 that converge toward the floating push plate 52. The two floating reset ramps 411 abut against the two elastic reset ramps 521, and the axes of each floating reset ramp 411 and each elastic reset ramp 521 are coaxially arranged with the axis of the floating water nozzle 4. The reset baffle 41 contacts the elastic reset ramps 521 through the floating reset ramps 411, thereby increasing the contact area between the reset baffle 41 and the floating push plate 52, improving the stability during reset, and further improving the accuracy of angle reset when angular deviation occurs.

[0032] Specifically, a raised limiting ring 522 is provided on the outer periphery of the inner circle of the floating push plate 52 facing the spring 51, and the spring 51 is sleeved on the outer side of the limiting ring 522. The limiting ring 522 further limits the spring 51 in the radial direction, preventing the spring 51 from shifting in the radial direction, improving the connection strength, and increasing stability and reliability.

[0033] Specifically, the floating nozzle 4 has a connector 42 at one end and a pipe connection 43 at the other end, with both extending out of the outer casing. The connector 42 connects to the plug to be connected, while the pipe connection 43 connects to the pipe. The floating nozzle 4 is a hollow, tubular floating nozzle. Liquid flows from the inside of the floating nozzle 4 through the liquid-cooled quick-connect device. Both the connector 42 and the pipe connection 43 extend out of the outer casing for easy connection to the plug and pipe.

[0034] Specifically, the connector 42 is provided with a quick-connect slot 421, and the pipe connection 43 is provided with a pagoda connector 431. The inner wall of the quick-connect slot 421 is provided with a conical guide slope 422 that gradually expands from the inside to the outside. The plug is inserted into the quick-connect slot 421 under the guidance of the guide slope 422. The guide slope 422 can further improve the connection success rate, and the pipe connection 43 increases the connection strength with the pipe through the pagoda connector 431.

[0035] Specifically, the outer casing includes a housing 1 and a plug 2. The housing 1 has an opening on its first side and a first through hole 11 on its second side. The plug 2 is fixedly installed on the first side of the housing 1 and has a second through hole 21. A connector 42 protrudes from the outer surface of the plug 2 through the second through hole 21, and a pipe connector 43 protrudes from the outer surface of the housing 1 through the first through hole 11. The diameters of both the first through hole 11 and the second through hole 21 are larger than the outer diameter of the floating nozzle 4. The plug 2 seals the opening of the housing 1, facilitating the installation of the floating nozzle 4 and the elastic floating assembly 5. There are gaps between the first through hole 11 and the second through hole 21 and the floating nozzle 4, thereby providing a deviation stroke for the axial angle of the floating nozzle 4, enabling the floating nozzle 4 to generate an angular deviation on its axis, further improving the deviation compensation capability.

[0036] Specifically, the outer casing is also provided with at least two connecting screws 3. A connecting boss 12 is provided on the first side of the casing 1 along the circumferential direction. The connecting boss 12 is provided with at least two threaded holes 121. The plug 2 is fixedly installed on the connecting boss 12. The plug 2 has a fixing countersunk hole 22 at the position corresponding to the threaded hole 121. The connecting screws 3 pass through the fixing countersunk hole 22 and are threadedly connected to the threaded hole 121. The casing 1 and the plug 2 are threadedly connected by the connecting screws 3, which facilitates assembly and production. The connecting boss 12 can fix the casing 1 to the cooling equipment and hide the casing 1 inside the cooling equipment, improving protection and aesthetics.

[0037] Specifically, a raised fixing ring 23 is provided on the outer periphery of the second perforation 21 facing the elastic floating component 5. The spring 51, located between the plug 2 and the reset baffle 41, is sleeved on the outside of the fixing ring 23. The connecting boss 12 is also provided with multiple connecting holes 122. The fixing ring 23 further limits the spring 51 in the radial direction, improving the connection strength of the spring 51. The connecting holes 122 facilitate the fixing of the outer shell to the cooling equipment by screws or other connections. The structure is simple and the cost is low.

[0038] Before assembling the liquid-cooled quick-connect assembly, inspect all components. Check the threads of the connecting screws 3 for integrity and damage, ensuring they can be screwed in and secured properly. Verify the dimensional accuracy of the floating nozzle 4, especially its outer diameter, ensuring it is smaller than the inner diameter of the housing to meet radial movement requirements. Also check the surface of the floating nozzle 4 for smoothness to avoid affecting its movement within the housing. Inspect the housing for defects such as cracks and deformation, and ensure its internal structure fits well with other components. Check the shape and size of the plug 2 to ensure it meets requirements and effectively secures the spring 51 within the housing. Inspect the two floating push plates 52 to confirm their angle, thickness, and other parameters meet design requirements, and that their surfaces are smooth to ensure proper guidance and positioning of the floating nozzle 4. Check the elasticity of the two springs 51, ensuring their elastic coefficient meets axial movement design requirements, and verifying the correct length and number of coils to prevent spring 51 failure during use.

[0039] When assembling the liquid-cooled quick-connect device, firstly, spring 51 is placed inside housing 1. During placement, one end of spring 51 should contact the bottom inner wall of housing 1, and the axis of spring 51 should coincide with the axis of housing 1 to ensure stable placement. Next, floating push plate 52 is placed inside housing 1, positioned on spring 51. Floating push plate 52 should be in close contact with spring 51, and its center should be aligned with the central axis of housing 1 to prevent displacement within housing 1. Then, floating water nozzle 4 is placed inside housing 1, with reset baffle 41 positioned on floating push plate 52. Reset baffle 41 and floating push plate 52 are tightly fitted, and floating water nozzle 4 can move freely radially within housing 1. Finally, another floating push plate 52 is placed on reset baffle 41. The floating push plate 52 is in close contact with the reset baffle 41. The two floating push plates 52 form a stable clamping structure for the floating nozzle 4. The angle of the floating push plate 52 is designed to guide the floating nozzle 4 back to the center position when it deviates. Then, another spring 51 is placed inside the housing 1, located on the second floating push plate 52. The placement of this spring 51 corresponds to that of the first spring 51, and one end is in close contact with the floating push plate 52 to ensure that it can provide a stable elastic force in the axial direction. Finally, the plug 2 is placed inside the housing 1 so that the plug 2 matches the internal structure of the housing 1, which can fix the spring 51 and the floating push plate 52 and other components inside the housing 1. The connecting screw 3 is passed through the fixing countersunk hole 22 on the plug 2 and connected to the threaded hole 121, thereby fixing the plug 2 to the housing 1 and sealing the housing 1.

[0040] After assembly, the liquid-cooled quick-connect assembly is debugged and verified. First, a visual inspection is performed to ensure all components are securely installed without looseness or misalignment. Then, tests are conducted simulating potential deviations in the liquid cooling system. For example, a certain radial, axial, or rotational force is manually applied to simulate interface deviations. The system is observed to see if the quick-connect assembly can float and adjust as designed, whether the floating nozzle 4 accurately returns to the center position, and whether the liquid cooling pipes achieve precise docking. If problems are found during debugging, such as inflexible floating or inaccurate docking, the quick-connect assembly needs to be inspected to identify the problem and make appropriate adjustments. This includes checking for damaged components and correct installation until the assembly functions normally and meets the precision requirements of the liquid cooling system.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
