Description

TECHNICAL FIELD

[0001] The utility model relates to a joint pressure reduction structure, especially a floating joint pressure reduction structure. BACKGROUND

[0002] Server cabinets are important infrastructures of data centers nowadays, and a large number of high-performance servers are usually arranged inside the server cabinets. With the improvement of server computing power and the increase of component density, the heat generated by the servers during operation increases significantly, and the lack of heat dissipation performance will directly affect the stability and service life of the servers. The traditional server cooling method mainly relies 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 demand, especially in high-density server cabinets. Due to the narrow spacing between servers, air flow is limited, leading to more serious heat accumulation problems, which further affects the operation performance of the servers. To solve the limitations of air cooling technology, the industry gradually adopts water cooling technology to cool the servers. However, the reliability of the water cooling system is extremely high for the precise electronic components inside the servers, and once water leakage occurs, it may cause serious damage. Therefore, the application of water cooling technology puts higher requirements on the sealing performance of the pipeline.

[0003] The existing water-cooled servers are usually designed with quick couplings to facilitate the quick connection or separation of the cooling pipeline between the movable side (server body) and the fixed side (server cabinet). The quick coupling allows flexible disassembly and maintenance of the server, but the butt joint process of the male and female couplings may cause radial offset or tolerance, which makes it difficult to align the couplings, thereby affecting the sealing performance of the couplings. To solve the problem of radial offset of the couplings, some server cabinets are designed to set guide posts on the fixed side and guide seats on the movable side, and the guide posts are inserted into the guide holes of the guide seats to realize accurate butt joint of the quick couplings. In addition, some designs use a floating coupling structure that can slide radially relative to the fixed seat to correct the radial offset of the couplings, further improving the sealing performance and operational convenience of the quick couplings.

[0004] As shown in Figures 1A-1E Prior art discloses a floating joint pressure reduction structure 1. The adapter seat 11 of the floating joint pressure reduction structure 1 can slide radially relative to the fixed seat 10 to overcome the problem of difficult alignment caused by radial offset or tolerance during butt joint with the butt joint side coupling. However, the floating joint pressure reduction structure 1 has the following disadvantages:

[0005] 1. Large radial space requirement

[0006] As shown in Figure 1AAs shown, the sliding gasket 12 needs to pass through the small inner diameter opening 16 inside the fixed seat 10, which has a high requirement for radial space. This design greatly limits the design flexibility of the floating joint pressure relief structure 1, especially in the case of insufficient radial space, making it difficult to be effectively applied.

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

[0008] As shown in Figure 1A and Figure 1B , the left end of the spring 13 abuts against the abutting surface of the adapter seat 11. When the spring 13 is compressed, an elastic restoring force is generated inside. This restoring force is applied to the left of the abutting surface of the adapter seat 11. At the same time, the right end of the spring 13 abuts against the inner side surface of the flange of the sliding gasket 12, applying a rightward force to the sliding gasket 12. When the adapter seat 11 is not tilted relative to the fixed seat 10, part of the force is transmitted to the sliding gasket 12 through the right end of the spring 13, and finally transmitted to the adapter seat 11 through the outer gasket 15 and the clasp 14. Another part of the force is transmitted to the sliding gasket 12 through the right end of the spring 13, and further applied to the inner surface of the closed side 102 of the fixed seat 10 through 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 the parts, and reducing the durability of the structure.

[0009] 3. Insufficient stability of the external clasp

[0010] As shown in Figure 1C , when the adapter seat 11 inside the fixed seat 10 is offset or tilted, causing the shaft center A' to not coincide with the shaft center A of the fixed seat 10 (for example, the adapter seat is tilted upward, and the shaft center A' is tilted upward and deviates from the shaft center A of the fixed seat), the stability of the clasp 14 will be significantly affected. As shown in Figure 1D , in this state, the left end of the spring 13 abuts against the abutting surface of the adapter seat 11, and the force is transmitted to the sliding gasket 12 and the fixed seat 10 through the right end of the spring 13. The force is transmitted to the elastic member 17 through the fixed seat 10, and then transmitted to the outer gasket 15 through the elastic member 17. At the same time, as shown in Figure 1E , the force is finally applied to the clasp 14 through the outer gasket 15. Since the clasp 14 only bears the force on one side and lacks external support structure, uneven force when passing through the opening of the clasp 14 can cause the clasp 14 to fail or loosen, negatively affecting the stability of the overall structure.

[0011] 4. Weak link in the force transmission mechanism

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

[0013] Therefore, how to solve the above technical problems is an urgent research direction. Content of the utility model

[0014] To effectively solve the above technical problems, the utility model aims at providing a floating joint pressure reduction 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 opposite to the spring force by the snap ring, effectively reducing the radial friction between the first sliding member and the fixed seat, so as to realize the smooth radial sliding function, and reduce the loss of the first sliding member. And, since the first sliding member is arranged to extend along the open side of the fixed seat and is sleeved on the outer periphery of the second segment of the adapter seat, the first flange thereof is attached to the inner peripheral plane of the fixed seat, without passing through the opening of the small inner diameter of the fixed seat, reducing the requirement for radial space and improving the adaptability of the floating joint pressure reduction 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 inclined, the snap ring can still maintain stable fixing function and is not affected by external force to be loose and fail.

DETAILED DESCRIPTION

[0053] The above-mentioned objects, structural and functional characteristics of the present application will be described with reference to the preferred embodiments of the drawings.

[0054] Please refer to Figure 2A , Figure 2B , Figure 3 and Figure 4 . Figure 2A is a cross-sectional view of the floating joint pressure relief structure of the first embodiment of the present application. Figure 2B is a force transmission path diagram when the floating joint pressure relief structure of the first embodiment of the present application is under pressure. Figure 3 is an exploded view of the floating joint pressure relief structure of the first embodiment of the present application. Figure 4 is an exploded view of part of the elements of the floating joint pressure relief structure of the first embodiment of the present application.

[0055] As shown in Figure 2A , Figure 3 , the present application provides a floating joint pressure relief structure 2, comprising a fixed seat 20, an adapter seat 21, a first sliding member 22, a spring 23, a clasp ring 24 and a second sliding member 25.

[0056] In the present embodiment, the fixing seat 20 comprises an open side 201 and a closed side 202, and has an accommodating space 203 inside. The accommodating space 203 is located between the open side 201 and the closed side 202, and is used to accommodate relevant components. The closed side 202 of the fixing seat 20 is provided with a through hole 2021. In the present embodiment, the overall shape of the fixing seat 20 is a cubic structure. The through hole 2021 may, for example, be circular or other geometric shapes, so as to facilitate the butt joint of a circular pipeline or relevant components of a corresponding shape.

[0057] In the present embodiment, the adapter seat 21 comprises 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 fixing seat 20, and the second section 212 extends from the open side 201 of the fixing seat 20 to the through hole 2021 of the fixing seat 20. An axial abutting surface 213 is provided between the first section 211 and the second section 212 of the adapter seat 21, which is formed by expanding radially outward. In the present embodiment, the adapter seat 21 is a hollow cylindrical structure, and the diameter of the first section 211 is greater than the diameter of the second section 212. The adapter seat 21 is provided with an axial through channel 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, which is used to connect, for example, a quick connector 28, so as to allow the quick assembly and disassembly of the quick connector 28. The inner surface of the second section 212 of the adapter seat 21 is provided with an internal threaded structure, which is used to connect the second sliding member (adapter) 25.

[0058] As shown in Figure 2A , Figure 3 , Figure 4 , the first sliding member 22 comprises a first barrel 221 and a first flange 222 formed by expanding radially outward from one end of the first barrel 221. The first barrel 221 has a hollow cylindrical (barrel) structure. The first barrel 221 extends in the direction of the open side 201 of the fixing seat 20 and is sleeved on the outer periphery of the second section 212 of the adapter seat 21. The first flange 222 comprises a first plane 2221 and a second plane 2222 opposite to the first plane 2221. The first plane 2221 of the first flange 222 is a flat contact surface, which is used to contact the inner circumferential plane of the closed side 202 of the fixing seat 20 and can be radially slidably attached to the inner circumferential plane of the fixing seat 20. This configuration allows the first sliding member 22 to slide in the radial direction, so as to adapt to the displacement requirement when the pipeline is butt jointed. 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 the first flange 222 thereof, which effectively increases the sliding contact area, so as to disperse the pressure acting on the contact site and reduce the rapid wear of the parts caused by long-time 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 arranged in the axial direction. 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 uniformly transmitted to the relevant components. By providing a stable positive force, the spring 23 ensures that the adapter 21 can quickly recover and remain in the predetermined fixed position after radial movement, 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 the slight tilting adjustment of the adapter 21, further improving the dynamic adaptability and operational stability of the structure.

[0060] In the present embodiment, the snap ring 24 is sleeved and fixed on the outer surface of the second section 212 of the adapter 21 and tightly engages with the inner edge of the first barrel 221 of the first sliding member 22. Specifically, as shown in Figure 4 In the present embodiment, part 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 the other part 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, achieving stable connection and precise positioning. In addition, the snap ring 24 provides a support force opposite to the spring force when the quick connector 28 does not move axially, effectively balancing the pushing force of the spring 23 on 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 operational stability of the first sliding member 22, and prolonging the service life of the relevant components.

[0061] In the embodiment, the second sliding member 25 is sleeved on the second section 212 of the adapter 21 and radially slides and adheres 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 through channel 2511 axially communicated with the second barrel 252. The second barrel 252 extends from one side of the base 251 in the axial direction to form a hollow cylindrical structure, penetrates 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 connecting an external pipeline (not shown in the figure) with the adapter 21. In the embodiment, the inner surface of the second barrel 252 is provided with an external thread structure and can be stably connected with the internal thread structure of the second section 212 of the adapter 21. In the embodiment, the base 251 of the second sliding member 25 further includes a second flange 253 radially outwardly expanded. The second flange 253 has a flat contact surface and radially slides and adheres to the outer surface of the closed side 202 of the fixed seat 20. Such a sliding fit allows the second sliding member 25 to move radially during the pipeline connection process, so as to adapt to the displacement requirement caused by the radial offset or tolerance during the pipeline butt joint process. In addition, the second sliding member 25 of the utility model embodiment also has the function of an adapter. The design of the utility model embodiment integrates the adapter and the second sliding member 25 into the same element, further simplifying the manufacturing process and assembly steps. At the same time, the design optimizes the overall stability of the structure, reduces the gap or looseness that may be caused by the multi-element connection, and significantly improves the reliability of the floating joint pressure relief structure 2.

[0062] As shown in Figure 2A , Figure 3 , the floating joint pressure relief structure 2 of the embodiment further includes an elastic member 26 and a sealing member 27. In the embodiment, the elastic member 26 and the sealing member 27 are O-rings, for example. 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 is in contact with the second flange 253 of the second sliding member 25. The main function of the elastic member 26 is to provide an interference amount to generate a positive force, maintain the structural stability of the element through the interference between adjacent elements, and ensure the force balance during operation. The sealing member 27 is embedded in the inner circumferential surface of the second section 212 of the adapter 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 pressure relief structure 2.

[0063] In the present embodiment, the floating joint pressure relief structure 2 further comprises a quick joint 28. The quick joint 28 is detachably connected to the first section 211 of the adapter seat 21. The quick joint 28, which is provided with a connecting component such as a thread, a buckle or a quick connecting mechanism at one end to match the first section 211 of the adapter seat 21, can achieve reliable fixation and convenient disassembly, allowing the user to quickly replace or adjust the joint according to different application requirements.

[0064] The first embodiment of the utility model supports the first sliding member 22 by the snap ring 24, provides a support force opposite to the spring force when the adapter seat 21 has no axial movement, reduces the friction between the fixed seat 20 and the first sliding member 22, realizes smooth sliding and reduces part loss. At the same time, the first barrel body 221 extends along the open side 201 of the fixed seat 20 and is sleeved on the outer periphery of the second section 212 of the adapter seat 21, and the first flange 222 is attached to the inner peripheral surface of the fixed seat 20, without passing through the small through hole 2021 of the fixed seat 20, reducing the radial space requirement and improving the structural adaptability. In addition, since the snap ring 24 is stably fixed between the adapter seat 21 and the first sliding member 22, rather than being arranged outside the fixed seat as in the prior art, even if the adapter seat 21 is tilted, the function can be maintained and the loosening failure can be avoided. The first embodiment of the utility model further integrates the adapter and the second sliding member 25 into the same element, simplifies the manufacturing and assembly process, and improves the structural stability and reliability.

[0065] In addition, as shown in Figure 2B The floating joint pressure relief structure of the embodiment of the utility model optimizes and improves the force transmission path when the structure is under pressure. The force originally transmitted to the first sliding member 22 from the right side of the spring 23 and applied to the inner surface of the second section 212 of the fixed seat 20 is transferred to the adapter seat 21 inside the fixed seat 20 by the snap ring 24. Compared with the prior art, the floating joint pressure relief structure of the utility model can reduce the friction 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 snap ring 24, the force is finally transmitted to the adapter seat 21 inside the fixed seat 20, effectively avoiding the situation that the force is transmitted to the elements outside the closed side 202 of the fixed seat 20. This improvement not only reduces the friction when the first sliding member 22 slides on the inner surface of the second section 212 of the fixed seat 20, but also eliminates the loosening or failure problem caused by the external elements bearing pressure, significantly improving the stability and reliability of the structure.

[0066] Please refer to Figure 5 . Figure 5 is a cross-sectional view of the floating joint pressure relief structure of the second embodiment of the utility model. As Figure 5As shown, the floating joint pressure relief structure 3 of the second embodiment of the present utility model differs from the first embodiment only in that the cross section of the snap ring 34 is designed as a rectangle. The rectangular cross section can provide higher contact stability, especially under high pressure or high load conditions, and can more effectively enhance the tightness between the snap ring 34 and the contact surface. The structures and configurations of the remaining elements are the same as those of the first embodiment, and the relevant details are described above and will not be repeated here.

[0067] As shown in Figure 6 , Figure 7 . Figure 6 is a cross-sectional view of the floating joint pressure relief structure of the third embodiment of the present utility model. Figure 7 is an exploded view of the floating joint pressure relief structure of the third embodiment of the present utility model.

[0068] As shown in Figure 6 , Figure 7 , the floating joint pressure relief structure 4 includes a fixed 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 pressure relief structure 4 of the third embodiment of the present utility model 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. The differences will be described in detail below, and the structures and configurations of the remaining elements are the same as those of the first embodiment, and the relevant details have been described above and will not be repeated here.

[0069] In this embodiment, the adapter seat 41 includes a first segment 411 and a second segment 412. The first segment 411 is in a cylindrical structure and is at least partially accommodated in the accommodation space 403 of the fixed seat 40. The second segment 412 is in a cylindrical structure with a diameter smaller than that of the first segment 411, which is arranged to pass through the open side 401 of the fixed seat 40 and extend axially until it exceeds the through hole 4021 of the fixed seat 40, forming an exposed end. The adapter seat 41 is provided with an axial through channel for fluid transmission. The inner surface of the first segment 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 segment 412 of the adapter seat 41 and attached to the outer surface of the closed side 402 of the fixed seat 40.
