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 through 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 Figure 1A As shown, the prior art discloses a floating joint structure 1. The adapter seat 11 of the floating joint 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 decompression structure 1 of the floating joint has the following disadvantages:

[0005] 1. Large radial space requirements

[0006] like Figure 1A As 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 in the case of insufficient radial space, and is difficult to be effectively applied.

[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 abutting surface of the adapter 11. When the spring 13 is compressed, an elastic restoring force is generated inside the spring 13. The restoring force is applied to the abutting surface of the adapter 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 force to the right on the sliding gasket 12.

[0009] 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 via the right end of the spring 13, and finally transmitted to the adapter seat 11 via 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 between the sliding gasket 12 and 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.

[0010] 3. Insufficient stability of the external buckle

[0011] 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 11 tilts upward and its axis A′ deviates upward from the axis A of the fixing seat 10), the stability of the retaining ring 14 will be significantly affected.

[0012] like 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 gasket 12 and the fixing seat 10 via the right end of the spring 13. The force is then transmitted to the elastic member 17 via the fixing seat 10, and then the elastic member 17 transmits the force to the outer gasket 15, and finally applied to the buckle 14 via the outer gasket 15.

[0013] At the same time, if Figure 1E As shown, the buckle 14 only bears the force on one side and lacks an external supporting 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.

[0014] 4. Weaknesses in the force transmission mechanism

[0015] 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.

[0016] In view of this, how to solve the above technical problems is an urgent research direction. Summary of the invention

DETAILED DESCRIPTION

[0051] 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.

[0052] Please refer to the attached picture, Figure 2 It is a three-dimensional exploded schematic diagram of the present invention; Figure 3 It is a cross-sectional combined schematic diagram of the present invention; Figure 4 yes Figure 3 A partial enlarged schematic diagram of Figure 5A , Figure 5B It is a schematic diagram of the operation of the present invention.

[0053] like Figure 2 , Figure 3 , Figure 4 As shown, the floating joint 2 includes a fixed seat 20 , an adapter seat 21 , a sliding member 25 , a hole clamping ring 24 , a sliding washer 22 and a spring 23 .

[0054] The fixing base 20 has an open side 201 and a closed side 202, and is provided with a receiving space 203 and an inner wall 204. The receiving space 203 is located between the open side 201 and the closed side 202, and is used to accommodate related components. The closed side 202 of the fixing base 20 is provided with a through hole 2021, and the open side 201 and the through hole 2021 are both connected to the receiving space 203 to form an internal channel structure. The inner wall 204 surrounds and faces the receiving space 203, and is provided with a surrounding inner wall groove 2041.

[0055] The adapter 21 includes a first section 211 and a second section 212. The adapter 21 is assembled with the fixed seat 20, the first section 211 extends from the accommodating space 203 toward the open side 201 of the fixed seat 20, and the second section 212 extends from the accommodating space 203 to the through hole 2021 of the closed side 202. In this embodiment, a portion of the first section 211 extends out of the open side 201 of the fixed seat 20, while the other portion is accommodated in the accommodating space 203. The diameter of the first section 211 is greater than the diameter of the second section 212, and an axial abutment surface 213 is formed by such a diameter difference. The axial abutment surface 213 is arranged between the first section 211 and the second section 212, and corresponds to the inner wall groove 2041 of the fixed seat 20. At the same time, a channel running through the axial direction is arranged inside the adapter 21 to allow stable transmission of the fluid.

[0056] The first section 211 of the adapter 21 is mainly used to match the connection of a quick connector 28, and its inner surface can be selected as a smooth surface or have an internal thread, a buckle structure, etc. according to the needs, so as to match the outer surface of the quick connector 28 to achieve quick assembly and disassembly operations. The inner surface of the second section 212 of the adapter 21 is provided with an internal thread structure for connecting the sliding member 25.

[0057] The sliding member 25 is sleeved with 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 sliding member 25 has a barrel 251 and a base 252. A sliding member channel is provided inside the sliding member 25 along its axial direction, and the channel is connected with the internal channel of the adapter 21, so as to realize smooth transmission of the fluid.

[0058] The barrel 251 extends axially from one side of the base 252 to form a hollow cylindrical structure. The barrel 251 penetrates into the accommodating space 203 from the outside of the closed side 202 of the fixed seat 20 through the through hole 2021 and is connected to the second section 212 of the adapter 21. The barrel 251 has a front end facing the adapter 21 and a terminal adjacent to the base 252. The terminal corresponds to the inner circumferential surface of one end of the second section 212 of the adapter 21 in the radial direction. The outer surface of the barrel 251 is provided with an external thread structure, which can be firmly screwed with the internal thread structure of the second section 212 of the adapter 21 to ensure the reliability of the connection.

[0059] The base 252 of the sliding member 25 is radially extended outward to form a base flange 253. The base 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 design allows the sliding member 25 to move radially during the pipeline connection process, thereby adapting to the displacement requirements caused by radial offset or tolerance, and improving the flexibility and adaptability of assembly.

[0060] This sliding fit structural design not only ensures a good fit between the sliding member 25 and the fixing seat 20, but also enables the entire floating joint 2 to adaptively adjust its position during installation and operation, thereby reducing stress and friction caused by offset.

[0061] The hole retaining ring 24 is arranged in the accommodating space 203 of the fixing seat 20, and has an outer ring portion 241 embedded in the inner wall groove 2041 of the fixing seat 20, and a retaining ring abutting surface 242 is exposed from the inner wall groove 2041 to the accommodating space 203, and the retaining ring abutting surface 242 faces the closed side 202 of the fixing seat 20 and is parallel to the axial abutting surface 213 of the adapter seat 21.

[0062] The sliding washer 22 is also disposed in the accommodating space 203 of the fixing seat 20, surrounding the outer circumference of the adapter seat 21. The sliding washer 22 has a first side 221 facing the open side 201 of the fixing seat 20, and a second side 222 facing the closed side 202 of the fixing seat 20. The first side 221 is closely attached to the snap ring abutting surface 242 of the abutting hole snap ring 24 and the axial abutting surface 213 of the adapter seat 21.

[0063] The spring 23 is axially sleeved on the outer periphery of the second section 212 of the adapter 21 and is arranged in the accommodating space 203 of the fixed seat 20. One end of the spring 23 abuts against the second side 222 of the sliding gasket 22, and the other end abuts against the inner surface of the closed side 202 of the fixed seat 20. A pre-pressure is generated by the spring 23 to form a stable positive force between the sliding gasket 22 and the closed side 202 of the fixed seat 20, ensuring that the adapter 21 can quickly return to the predetermined fixed position after radial movement to avoid structural deviation. At the same time, the elastic compression stroke of the spring 23 allows it to adapt to the tolerance changes in the axial direction, so that the adapter 21 can withstand a certain range of dimensional errors. The flexible design of the spring 23 also supports the adapter 21 to perform slight tilt adjustments, further improving the dynamic adaptability and operational stability of the structure.

[0064] Please refer to Figure 2 , Figure 3 As shown, the decompression structure of the floating joint of this embodiment further includes an elastic member 26 and a sealing member 27 .

[0065] The elastic member 26 (eg, an elastic O-ring) is embedded in an annular groove on the outer surface of the closed side 202 of the fixing seat 20 and contacts the base flange 253 of the sliding member 25 to provide interference to generate a positive force.

[0066] The seal 27 (eg, a sealing ring) is sleeved (embedded) at the end of the barrel 251 of the sliding member 25 and is in sealing contact with the inner circumferential surface of one end of the second section 212 of the adapter 21 to improve the sealing performance of the joint.

[0067] Please refer to Figure 4 As shown, in this embodiment, the preload of the spring 23 (as indicated by the leftward arrow F1 in the figure) is applied to the second side 222 of the sliding gasket 22, so that the first side 221 can simultaneously axially abut against the retaining ring abutting surface 242 of the retaining ring 24 for the hole and the axial abutting surface 213 of the adapter 21. Figure 3 When the quick connector 28 is in a state of no axial movement, the retaining ring abutting surface 242 of the hole retaining ring 24 and the axial abutting surface 213 of the adapter seat 21 jointly provide two supporting forces (such as the two arrows F2 and F3 pointing to the right in the figure) that are opposite to the preload of the spring 23, effectively balancing the preload applied by the spring 23 on the sliding gasket 22. With this structural design, the retaining ring abutting surface 242 provides additional supporting force F3, effectively reducing the friction between the sliding gasket 22 and the adapter seat 21 caused by radial sliding. This improves the Figure 3 The sliding performance and running stability of the middle sliding member 25 significantly improve the reliability and service life of the floating joint 2, while optimizing the stability of the overall structure of the floating joint 2, overcoming the shortcomings of the external clamping ring in the prior art, such as insufficient stability and weak force transmission.

[0068] In addition, the spring 23 and the sliding gasket 22 are fixed in the accommodating space 203 inside the fixed seat 20 to prevent their weight from being directly added to the adapter 21, thereby reducing the load pressure of the adapter 21. This design effectively reduces the structural deviation and instability caused by gravity. When the first side 221 of the sliding gasket 22 abuts the retaining ring abutting surface 242 of the retaining ring 24 for the hole and the axial abutting surface 213 of the adapter 21, the pre-pressure of the spring 23 helps to balance the stress distribution in the overall structure, ensuring that the adapter 21 maintains flexible sliding performance during operation. At the same time, the connection between the quick connector 28 and the adapter 21 benefits from the weight reduction design, reduces the influence of friction, can reliably maintain stability, and avoids the quick connector 28 from being difficult to hover in a fixed position due to gravity.

[0069] Furthermore, the sliding gasket 22 is arranged in the accommodating space 203 inside the fixing seat 20, so that the structure of the present application can be applied to the fixing seat 20 with a smaller radial space, thereby overcoming the problem in the conventional technology that the first sliding member 12 needs to pass through the opening 16 with a smaller inner diameter on one side of the fixing seat 10, which has a higher requirement for radial space.

[0070] Please continue to refer to Figure 5A , Figure 5B The axis 21 of the adapter and the axis of the fixing base 20 are non-coaxial or coaxial. Figures 2 to 4 , when the axis A2 of the adapter 21 is coaxial with the axis A1 of the fixed base 20 (such as Figure 5B), the components therebetween include a sliding gasket 22 and a hole retaining ring 24 which can effectively maintain their symmetry, so that the first side 221 of the sliding gasket 22 is evenly abutted between the retaining ring abutting surface 242 and the axial abutting surface 213 of the adapter 21, providing a stable supporting force, thereby reducing radial friction and ensuring the smoothness of radial sliding performance.

[0071] In addition, when the adapter 21 is displaced upward due to external force or installation error (such as Figure 5A ), its axis A2 is non-coaxially offset from the axis A1 of the fixing seat 20. At this time, the first side 221 of the sliding gasket 22 will still adaptively maintain the abutment state with the snap ring abutment surface 242 and the axial abutment surface 213 according to its design characteristics. In the case of offset, the additional support force provided by the snap ring abutment surface 242 can effectively compensate for the uneven force distribution on the sliding gasket 22, thereby reducing the friction between the sliding gasket 22 and the adapter 21, and avoiding excessive wear or structural instability caused by offset.

[0072] Please continue to refer to the attached pictures. Figure 6-Figure 7 3D exploded and cross-sectional schematic diagrams of another embodiment of the present invention are shown in the figure. As shown in the figure, the difference between the floating joint 2 of this embodiment and the above-mentioned one is that the design and configuration of the adapter 21a, the sliding member 25a and the fastener 216a are slightly different. These differences will be described in detail below. The other component structures and configurations, component symbols, functions and effects that are the same as those of the previous embodiment have been described in the previous embodiment and will not be repeated here.

[0073] In this embodiment, the second section 212a of the adapter 21a extends from the accommodating space 203 through the through hole 2021 of the closed side 202, and protrudes to the outside of the fixing base 20 after passing through the through hole 2021, and is exposed to the external environment. An annular groove 215a is provided on the outer surface of the second section 212a, and the annular groove 215a is located at the exposed portion of the second section 212a and is adjacent to the outer surface of the closed side 202 of the fixing base 20.

[0074] The sliding member 25a is, for example, a gasket, and has an opening at its center adapted to the outer surface of the second end 212a of the adapter 21a, so as to be sleeved on the second section 212a of the adapter 21a from the outside of the closed side 202 of the fixed seat 20. One side of the sliding member 25a is attached to the outer surface of the closed side 202 of the fixed seat 20, ensuring that the sliding member 25a is stably attached while allowing it to slide radially on the outer surface of the closed side 202 of the fixed seat 20.

[0075] The fastener 216a, such as a retaining ring or a nut, is sleeved on the outer surface of the second section 212a of the adapter 21a from the outside of the closed side 202 of the fixing seat 20, and is tightly clamped in the annular groove 215a of the second section 212a. In this way, the fastener 216a is adjacent to the sliding member 25a to strengthen the axial limitation of the sliding member 25a and prevent it from axially falling out along the second section 212a of the adapter 21a.

[0076] The above is a detailed description of the present invention, and the above is only a preferred embodiment of the present invention, which should not limit the scope of the present invention. That is, all equivalent changes and modifications made according to the present invention should still fall within the scope of the patent of the present invention.
