Description

Technical Field

[0001] The invention relates to a joint decompression structure, in particular to a floating joint decompression structure. Background Art

[0002] Server cabinets are important infrastructure in today's data centers, and a large number of high-performance servers are usually arranged inside them. With the improvement of server computing power and the increase in component density, the heat generated by servers during operation has increased significantly, and the lack of heat dissipation performance will directly affect the stability and service life of the server. Traditional server heat dissipation methods mainly rely on air cooling technology. However, with the improvement of server performance, the heat dissipation efficiency of air cooling technology has been difficult to meet the needs, especially in high-density server cabinets. Due to the narrow spacing between servers and limited air flow, the problem of heat accumulation has become more serious, which in turn affects the operating efficiency of the server. In order to solve the limitations of air cooling technology, the industry has gradually adopted water cooling technology to dissipate heat from servers. However, the precision electronic components inside the server have extremely high requirements for the reliability of the water cooling system. Once a leak occurs, it may cause serious damage. Therefore, the application of water cooling technology puts higher requirements on the sealing of the pipeline.

[0003] Existing water-cooled servers are usually designed with quick connectors to facilitate the quick connection or separation of the cooling pipes on the movable side (server body) and the fixed side (server cabinet). Quick connectors allow the server to be flexibly disassembled and maintained, but the joints between the male and female connectors may be difficult to align due to radial offset or tolerance, thereby affecting the sealing performance of the connectors. In order to solve the problem of radial offset of the connectors, some server cabinet designs are equipped with guide columns on the fixed side and guide seats on the movable side, and the guide columns are inserted into the guide holes of the guide seats to achieve precise docking of the quick connectors. In addition, some designs correct the radial offset of the connector by using a floating connector structure that can slide radially relative to the fixed seat, further improving the sealing and ease of operation of the quick connector.

[0004] like Figures 1A to 1E As shown, the prior art discloses a floating joint decompression structure 1. The adapter seat 11 of the floating joint decompression structure 1 can slide radially relative to the fixed seat 10 to overcome the problem of difficulty in alignment due to radial offset or tolerance during docking with the docking side joint. However, the floating joint decompression structure 1 has the following disadvantages:

[0005] 1. Large radial space requirements

[0006] like Figure 1AAs shown, the sliding gasket 12 needs to pass through the opening 16 with a smaller inner diameter inside the fixing seat 10, which has a high requirement for radial space. This design greatly limits the design flexibility of the floating joint decompression structure 1, especially when the radial space is insufficient, it is difficult to effectively apply.

[0007] 2. The friction force when the sliding gasket slides on the inner surface of the fixed seat is large

[0008] like Figure 1A and Figure 1B As shown, the left end of the spring 13 abuts against the abutment surface of the adapter seat 11. When the spring 13 is compressed, an elastic restoring force is generated inside the spring 13. The restoring force is applied to the abutment surface of the adapter seat 11 to the left. At the same time, the right end of the spring 13 abuts against the inner side of the flange of the sliding gasket 12, exerting a rightward force on the sliding gasket 12. When the adapter seat 11 is not tilted relative to the fixed seat 10, a part of the force is transmitted to the sliding gasket 12 via the right end of the spring 13, and finally transmitted to the adapter seat 11 through the outer gasket 15 and the buckle 14. The other part of the force is transmitted to the sliding gasket 12 via the right end of the spring 13, and further applied to the inner surface of the closed side 102 of the fixed seat 10 via the sliding gasket 12, resulting in a large friction force when the sliding gasket 12 slides radially on the inner surface of the closed side 102 of the fixed seat 10, affecting the sliding performance, accelerating the wear of parts, and reducing the durability of the structure.

[0009] 3. Insufficient stability of the external buckle

[0010] like Figure 1C As shown, when the adapter 11 in the fixing seat 10 is offset or tilted so that the axis A' does not coincide with the axis A of the fixing seat 10 (for example, the adapter tilts upward and its axis A' deviates upward from the axis A of the fixing seat), the stability of the buckle 14 will be significantly affected. Figure 1D As shown, in this state, the left end of the spring 13 abuts against the abutting surface of the adapter seat 11, and its force is transmitted to the sliding pad 12 and the fixed seat 10 via the right end of the spring 13. The force is transmitted to the elastic member 17 via the fixed seat 10, and then the elastic member 17 transmits the force to the outer pad 15. At the same time, Figure 1E As shown, the force is finally applied to the buckle 14 through the outer gasket 15. Since the buckle 14 only bears the force on one side and lacks an external support structure, when the force passes through the opening of the buckle 14, the uneven force may cause the buckle 14 to fail or loosen, which has a negative impact on the stability of the overall structure.

[0011] 4. Weaknesses in the force transmission mechanism

[0012] Please refer to Figure 1C to Figure 1EAs shown, the buckle 14 is a key component of structural support, and its stability is easily affected by various factors, such as the direction of external force, structural deviation, etc., which further leads to a weak link in force transmission and reduces the stability and reliability of the overall structure.

[0013] In view of this, how to solve the above technical problems is an urgent research direction. Summary of the invention

[0014] In order to effectively solve the above technical problems, the purpose of the present invention is to provide a floating joint decompression structure. In the process of docking with the docking side, when the adapter seat slides radially, the first sliding member is provided with a supporting force in the opposite direction of the spring force through the snap ring, which effectively reduces the radial friction between the first sliding member and the fixed seat, thereby realizing a smooth radial sliding function and reducing the loss of the first sliding member. In addition, since the first sliding member is configured such that its first barrel extends along the open side direction of the fixed seat and is sleeved on the second section of the outer periphery of the adapter seat, its first flange is attached to the inner circumferential plane of the fixed seat, and does not need to pass through the opening of the smaller inner diameter of the fixed seat, which reduces the demand for radial space and improves the adaptability of the floating joint decompression structure. In addition, since the snap ring is located inside the fixed seat and is directly fixed between the adapter seat and the first sliding member, even if the adapter seat is tilted, the snap ring can still maintain a stable fixing function and will not be loosened and failed due to external forces.

DETAILED DESCRIPTION

[0053] The above-mentioned objects and the structural and functional characteristics of the present invention will be described based on the preferred embodiments shown in the accompanying drawings.

[0054] See also Figure 2A , Figure 2B , Figure 3 and Figure 4 shown. Figure 2A It is a cross-sectional schematic diagram of the floating joint pressure reducing structure according to the first embodiment of the present invention. Figure 2B It is a schematic diagram of the force transmission path of the floating joint decompression structure of the first embodiment of the present invention when it is under pressure. Figure 3 It is an exploded schematic diagram of the floating joint pressure reducing structure according to the first embodiment of the present invention. Figure 4 It is an exploded schematic diagram of some components of the floating joint decompression structure according to the first embodiment of the present invention.

[0055] like Figure 2A , Figure 3 As shown, the present invention provides a floating joint decompression structure 2, which includes a fixing seat 20, an adapter seat 21, a first sliding member 22, a spring 23, a clamping ring 24 and a second sliding member 25.

[0056] In this embodiment, the fixing base 20 includes an open side 201 and a closed side 202, and a receiving space 203 is provided therein. The receiving space 203 is located between the open side 201 and the closed side 202, and is used to accommodate related components, and the closed side 202 of the fixing base 20 is provided with a through hole 2021. In this embodiment, the overall shape of the fixing base 20 is a cubic structure. The through hole 2021 can be, for example, circular or other geometric shapes, so as to facilitate docking with circular pipelines or related components of corresponding shapes.

[0057] In the present embodiment, the adapter seat 21 includes a first section 211 and a second section 212. The first section 211 is at least partially accommodated in the accommodating space 203 of the open side 201 of the fixed seat 20, and the second section 212 is penetrated from the open side 201 of the fixed seat 20 and extends to the through hole 2021 of the fixed seat 20. An axial abutment surface 213 extending radially outward is provided between the first section 211 and the second section 212 of the adapter seat 21. In the present embodiment, the adapter seat 21 is a hollow cylindrical structure, and the diameter of the first section 211 is larger than the diameter of the second section 212. An axially through channel is provided in the adapter seat 21 for the transmission of fluid. In the present embodiment, at least one of the inner and outer surfaces of the first section 211 of the adapter seat 21 is provided with a threaded structure for connection with, for example, a quick connector 28 to allow quick assembly and disassembly of the quick connector 28. An inner surface of the second section 212 of the adapter seat 21 is provided with an internal thread structure for connecting with the second sliding member (adapter) 25 .

[0058] like Figure 2A , Figure 3 , Figure 4 As shown, the first slide 22 comprises a first barrel 221 and a first flange 222 formed by radially expanding outwards from one end of the first barrel 221. The first barrel 221 has a hollow cylindrical (tube) shape structure. The first barrel 221 extends along the open side 201 direction of the holder 20 and is sleeved on the second section 212 outer periphery of the adapter 21. The first flange 222 comprises a first plane 2221 and a second plane 2222 relative to the first barrel 222. The first plane 2221 of the first flange 222 is a flat contact surface, which is used to contact the inner peripheral plane of the closed side 202 of the holder 20, and can be attached to the inner peripheral plane of the holder 20 radially slidably. This configuration allows the first slide 22 to slide in the radial direction, thereby adapting to the displacement demand when the pipeline is docked. At the same time, the first sliding member 22 contacts the inner circumferential plane of the closed side 202 of the fixing seat 20 through its first flange 222. This design effectively increases the sliding contact area, thereby dispersing the pressure acting on the contact part and reducing the rapid wear of parts caused by long-term operation.

[0059] In the present embodiment, the spring 23 is sleeved on the outer periphery of the second section 212 of the adapter 21 and is arranged axially. One end of the spring 23 abuts against the axial abutment surface 213 of the adapter 21 to provide a stable support base point, and the other end abuts against the second plane 2222 of the first flange 222 of the first sliding member 22 to ensure that the force of the spring 23 can be evenly transmitted to the relevant components. The spring 23 ensures that the adapter 21 can quickly recover and remain in a predetermined fixed position after radial movement by providing a stable positive force, thereby avoiding structural deviation. At the same time, the compression stroke of the spring 23 can adapt to the tolerance changes in the axial direction, allowing the adapter 21 to withstand a certain range of dimensional errors during operation. In addition, the flexible design of the spring 23 enables it to support slight tilt adjustments of the adapter 21, further improving the dynamic adaptability and operational stability of the structure.

[0060] In this embodiment, the clamping ring 24 is sleeved and fixed on the outer surface of the second section 212 of the adapter 21, and forms a tight clamping fit with the inner edge of the first barrel 221 of the first sliding member 22. Figure 4 As shown, in this embodiment, a portion of the snap ring 24 is embedded in the first annular groove 214 on the outer periphery of the second section 212 of the adapter 21, and at the same time, another portion of the snap ring 24 is embedded in the second annular groove 223 on the inner edge of the first barrel 221 of the first sliding member 22, so as to achieve a stable connection and precise positioning. In addition, when the quick connector 28 does not move axially, the snap ring 24 provides a supporting force in the opposite direction of the spring force, effectively balancing the thrust applied by the spring 23 to the first sliding member 22, thereby reducing the friction between the fixed seat 20 and the first sliding member 22, improving the sliding performance and operating stability of the first sliding member 22, and extending the service life of related components.

[0061] In the present embodiment, the second sliding member 25 is sleeved on the second section 212 of the adapter 21, and can be radially slidably attached to the outer surface of the closed side 202 of the fixed seat 20. Specifically, the second sliding member 25 has a base 251 and a second barrel 252. The base 251 is provided with a passage 2511 that runs through and is axially communicated with the second barrel 252. The second barrel 252 extends axially from a side of the base 251 to form a hollow cylindrical structure, is arranged in the through hole 2021 of the fixed seat 20 and is connected with the second section 212 of the adapter 21, and is used for an external pipeline (not shown) to be communicated with the adapter 21. In the present embodiment, the inner surface of the second barrel 252 is provided with an external thread structure, which can be stably connected with the internal thread structure of the second section 212 of the adapter 21. In the present embodiment, the base 251 of the second sliding member 25 also includes a second flange 253 that is formed by radially expanding outwards. The second flange 253 has a flat contact surface and can be radially slidably attached to the outer surface of the closed side 202 of the fixing seat 20. This sliding fit allows the second sliding member 25 to move radially during the pipeline connection process, thereby adapting to the displacement requirements caused by radial offset or tolerance during the pipeline docking process. In addition, the second sliding member 25 of the embodiment of the present invention also has the function of an adapter. The embodiment of the present invention integrates the adapter and the second sliding member 25 into a design of the same component, further simplifying the manufacturing process and assembly steps. At the same time, this design optimizes the overall stability of the structure, reduces the gap or looseness that may be caused by the connection of multiple components, and significantly improves the reliability of the floating joint decompression structure 2.

[0062] like Figure 2A , Figure 3 As shown, the floating joint decompression structure 2 of this embodiment also includes an elastic member 26 and a sealing member 27. In this embodiment, the elastic member 26 and the sealing member 27 are, for example, O-rings. The elastic member 26 is embedded in the third annular groove 204 on the outer surface of the closed side 202 of the fixed seat 20, and contacts the second flange 253 of the second sliding member 25. The main function of the elastic member 26 is to provide interference to generate a positive force, maintain the structural stability of the element through interference with adjacent elements, and ensure force balance during operation. The sealing member 27 is embedded in the inner circumferential surface of the second section 212 of the adapter seat 21, and is in sealing contact with the second barrel 252 of the second sliding member 25, further improving the sealing performance of the floating joint decompression structure 2.

[0063] In this embodiment, the floating joint decompression structure 2 further includes a quick joint 28. The quick joint 28 is detachably connected to the first section 211 of the adapter 21. The quick joint 28 has a connection component, such as a thread, a buckle or a quick connection mechanism, at one end thereof, which matches the first section 211 of the adapter 21, and can achieve reliable fixation and convenient disassembly and assembly, allowing the user to quickly replace or adjust the joint according to different application requirements.

[0064] The first embodiment of the present invention supports the first sliding member 22 through the snap ring 24, and provides the first sliding member 22 with a supporting force opposite to the spring force when the adapter 21 has no axial movement, so as to reduce the friction between the fixed seat 20 and the first sliding member 22, realize smooth sliding and reduce the loss of parts. At the same time, the first barrel 221 extends along the open side 201 direction of the fixed seat 20 and is sleeved on the outer periphery of the second section 212 of the adapter 21, and its first flange 222 is attached to the inner circumferential plane of the fixed seat 20, without passing through the smaller through hole 2021 of the fixed seat 20, reducing the radial space requirement and improving the adaptability of the structure. In addition, since the snap ring 24 is stably fixed between the adapter 21 and the first sliding member 22, rather than being arranged on the outer side of the fixed seat as in the conventional technology, even if the adapter 21 is tilted, the function can be kept intact to avoid loosening and failure. The first embodiment of the present invention also integrates the adapter and the second sliding member 25 into the same component, simplifies the manufacturing and assembly process, and improves the structural stability and reliability.

[0065] In addition, if Figure 2B As shown, the floating joint decompression structure of the embodiment of the present invention is optimized and improved in the force transmission path when the structure is under pressure. The force originally transmitted from the right side of the spring 23 to the first sliding member 22 and applied to the inner surface of the second section 212 of the fixed seat 20 will be transferred to the adapter seat 21 located inside the fixed seat 20 through the retaining ring 24. Compared with the prior art, the floating joint decompression structure of the present invention can reduce the friction force when the first sliding member 22 slides on the inner surface of the second section 212 of the fixed seat 20 when under pressure. In addition, through the internal retaining ring 24, the force is finally transmitted to the adapter seat 21 inside the fixed seat 20, effectively avoiding the situation where the force is transmitted to the external components of the closed side 202 of the fixed seat 20. In addition to reducing the friction force when the first sliding member 22 slides on the inner surface of the second section 212 of the fixed seat 20, this improvement also eliminates the problem of loosening or failure caused by the pressure on the external components, significantly improving the stability and reliability of the structure.

[0066] See also Figure 5 shown. Figure 5 FIG. 2 is a cross-sectional schematic diagram of a floating joint pressure reducing structure according to a second embodiment of the present invention. Figure 5As shown, the floating joint decompression structure 3 of the second embodiment of the present invention is different from the first embodiment only in that the cross section of the clamp ring 34 is designed to be rectangular. The rectangular cross section can provide higher contact stability, especially under high pressure or high load conditions, and can more effectively enhance the fit between the clamp ring 34 and the contact surface. The remaining component structures and configurations are the same as those of the first embodiment. Please refer to the above description for relevant details, which will not be repeated here.

[0067] See also Figure 6 , Figure 7 shown. Figure 6 It is a cross-sectional schematic diagram of a floating joint decompression structure according to a third embodiment of the present invention. Figure 7 It is an exploded schematic diagram of a floating joint pressure reducing structure according to a third embodiment of the present invention.

[0068] like Figure 6 , Figure 7 As shown, the floating joint decompression structure 4 includes a fixing seat 40, an adapter seat 41, a first sliding member 42, a spring 43, a snap ring 44, a second sliding member 45 and a fastener 47. The main difference between the floating joint decompression structure 4 of the third embodiment of the present invention and the first embodiment is that the design and configuration of the adapter seat 41, the second sliding member 45 and the fastener 47 are slightly different. These differences will be described in detail below. The structure and configuration of the remaining components are the same as those of the first embodiment. The relevant details have been described in the above description and will not be repeated here.

[0069] In this embodiment, the adapter seat 41 includes a first section 411 and a second section 412. The first section 411 is a cylindrical structure, at least partially contained in the accommodating space 403 of the fixed seat 40. The second section 412 is a cylindrical structure with a reduced diameter compared to the first section 411, which is arranged from the open side 401 of the fixed seat 40, extending axially until it exceeds the through hole 4021 of the fixed seat 40 to form an exposed end. The adapter seat 41 is provided with an axially penetrating channel for fluid transmission. The inner surface of the first section 411 of the adapter seat 41 is provided with an internal thread structure (not shown), which can be connected with a quick connector 48 to allow quick assembly and disassembly of the quick connector 48. The second sliding member 45 is sleeved on the second section 412 of the adapter seat 41 and attached to the outer surface of the closed side 402 of the fixed seat 40. This configuration ensures that the second sliding member 45 is stably attached while allowing it to slide radially on the outer surface of the closed side 402 of the fixed seat 40.

[0070] like Figure 7 As shown, in this embodiment, the second sliding member 45 is an annular sheet structure, and a through opening is provided in the center thereof. The inner circumference of the opening is precisely matched with the outer surface of the second section 412 of the adapter 41, ensuring that the second sliding member 45 is firmly fixed after installation and has the ability to slide radially.

[0071] In this embodiment, the fastener 47 is a C-shaped ring structure with fixing holes at both ends to facilitate tool installation and removal. The fastener 47 may also be a nut or other components. The fastener 47 is sleeved on the outer surface of the second section 412 of the adapter 41 and contacts the second sliding member 45 on the outer surface of the fixed seat 40 to enhance the axial upper limit effect of the second sliding member 45 and allow it to slide radially on the outer surface of the closed side 402 of the fixed seat 40. Specifically, the fastener 47 is embedded in another fourth annular groove 413 on the outer surface of the second section 412 of the adapter 41, and its inner circumference is tightly fitted with the outer surface of the adapter 41 to ensure firmness and stability.

[0072] The third embodiment of the present invention supports the first sliding member 42 through a snap ring 44, provides a reverse support force when the adapter 41 has no axial movement, reduces the friction between the fixed seat 40 and the first sliding member 42, achieves smooth sliding and reduces parts loss. The first barrel 421 of the first sliding member 42 is sleeved on the outer periphery of the adapter 41, and the first barrel 421 extends along the open side 401 direction of the fixed seat 40 and is sleeved on the outer periphery of the second section 412 of the adapter 41, and its first flange 422 is attached to the inner circumferential plane of the fixed seat 40, reducing radial space requirements and improving structural adaptability. The snap ring 44 is stably fixed between the adapter 41 and the first sliding member 42, and can withstand the tilt of the adapter 41 to avoid loosening and failure. In addition, the fastener 47 is sleeved on the second section 412 of the adapter 41 and contacts with the second sliding member 45 to strengthen the axial limiting effect of the second sliding member 45.

[0073] See also Figure 8 shown. Figure 8 Schematic diagram of the operation of the floating joint pressure relief structure according to an embodiment of the present invention. Figure 8 As shown, the floating joint decompression structure 2 of the present invention realizes stable and reliable pipe docking through its internal structure. Its design enables the floating joint decompression structure 2 to adapt to radial or axial tolerances during the docking process with the docking side female head 9, ensuring that the docking side female head 9 and the quick connector 28 of the floating joint decompression structure 2 can accurately and tightly fit. At the same time, the first sliding member 22 and the retaining ring 24 and other structures contained inside can reduce friction resistance, improve sliding smoothness, and reduce parts loss. The retaining ring 24 is stably fixed between the adapter seat 21 and the first sliding member 22, rather than being arranged outside the fixed seat 20, and can withstand the tilt of the adapter seat 21 to avoid loosening and failure. In addition, the second sliding member 25 of the embodiment of the present invention also has the function of an adapter, further simplifying the manufacturing process and assembly steps.
