Description

Technical Field

[0001] The utility model relates to a joint floating fixing seat decompression structure, in particular to a joint floating fixing seat decompression structure which can reduce the radial sliding resistance of a floating joint. Background Art

[0002] As server computing performance continues to improve, the heat generated by the computing units inside the servers also increases. In addition, multiple servers are often installed in a server cabinet at the same time. The space between each server is very narrow, and it is impossible to set up additional heat dissipation modules to dissipate heat for each server. Therefore, water cooling is currently used to provide heat dissipation for each server in the server cabinet. Since there are sophisticated electronic parts in the server, various water cooling pipe configurations must avoid water leakage at each connection point to prevent damage to electronic components caused by water leakage.

[0003] In order to prevent water leakage, most of the server pipes use hard or metal pipes to configure the cooling water pipes, and a male and a female quick connector are correspondingly provided on the server (active side) and the server cabinet (fixed side) for docking, so that the water channels on the active side and the fixed side can be quickly connected or separated. Since the male and female connectors have a small radial tolerance when assembled, in order to facilitate the rapid correction of the radial tolerance of the two quick connectors, at least one guide column is currently provided near the position where the female connector is provided on the fixed side (server cabinet), and a guide seat is provided on the side of the position where the male connector is provided on the active side (server) corresponding to the position of the guide column, and the guide seat has a guide hole. When the male and female connectors are assembled, the guide column is first inserted into the guide hole of the guide seat, and the two quick connectors with radial tolerance are guided by the guide column and the guide seat to guide the two quick connectors to be close to the coaxial center before the two connectors are aligned and connected in series.

[0004] In addition, in order to save space inside the server cabinet, some businesses have omitted the use of guide columns and guide seats. Therefore, they have provided a fixing seat for radial offset correction specifically for the radial setting of the two mutually docking male and female connectors, and provided an inclined surface at the position where the inner hole of the female connector first contacts the male connector when docking. When combined with the fixing seat, radial offset correction can be provided when the male and female connectors are assembled. However, since the fixing seat and the adapter are clamped relative to each other by two gaskets, a positive force is formed between the fixing seat and the adapter, so that the adapter can hover in a fixed position in the radial activity space after radial movement relative to the fixing seat. However, when the positive force generated by the two gaskets on the fixing seat is too large, the resistance will be too large, making it difficult for the adapter to slide. On the contrary, when the positive force generated by the two gaskets is too small, the adapter cannot be maintained in the position after the movement. Therefore, how to improve the conventional deficiencies is the primary goal of people in this field. Utility Model Content

DETAILED DESCRIPTION

[0024] The above-mentioned purpose and the structural and functional characteristics of the present invention will be described based on the preferred embodiments of the accompanying drawings.

[0025] Please refer to this utility model, Figure 1 This is a three-dimensional exploded view of an embodiment of the joint floating fixing seat decompression structure of the utility model; Figure 2 It is a combined cross-sectional view of an embodiment of the joint floating fixing seat decompression structure of the utility model; Figure 3 It is a partially enlarged schematic diagram of the combined cross-sectional view of the decompression structure of the floating fixing seat of the joint of the utility model; Figure 4 It is a schematic diagram of the operation of an embodiment of the joint floating fixing seat decompression structure of the utility model; and, Figure 5 It is a schematic diagram of the operation of an embodiment of the joint floating fixing seat decompression structure of the utility model.

[0026] As the utility model Figure 1 and Figure 2 As shown, the utility model provides a joint floating fixing seat decompression structure, comprising: a fixing seat 1, an adapter seat 2, an elastic element 3, a fixing element 4, a supporting gasket 5 and a spring 6.

[0027] The fixing base 1 has a first side 11 and a second side 12 on opposite sides. The fixing base 1 has an accommodating space 13 inside. The accommodating space 13 is located between the first side 11 and the second side 12. The first side 11 forms a through hole 111 to make the first side 11 open. The through hole 111 is connected to the accommodating space 13. The second side 12 is a closed side having a through hole 121. The through hole 121 is connected to the accommodating space 13.

[0028] The two ends of the adapter 2 are respectively provided with a joint section 22 and a sleeve section 21, and a buffer section 23 is provided between the joint section 22 and the sleeve section 21, and an axial stopper 24 is formed at the joint between the joint section 22 and the buffer section 23. The sleeve section 21 passes through the accommodating space 13 of the fixing seat 1 and protrudes outward through the through hole 121 of the fixing seat 1, so that the buffer section 23 is disposed in the through hole 121. The joint section 22 of the adapter 2 can be docked with a male connector 7, and the joint section 22 can also be docked with other structures or components without limitation, or the joint section 22 can extend another structure to be used in conjunction with other components.

[0029] The elastic element 3 is sleeved on the outer portion of the sleeve section 21 of the adapter 2, and has two opposite sides, namely a front end 31 and a rear end 32, and the rear end 32 abuts against the second side 12 of the fixing base 1. In detail, the elastic element 3 can generate a positive force by being axially compressed at both ends of the front end 31 and the rear end 32; for example, a spring, a gasket or a spring, etc., but the present invention is not limited thereto.

[0030] For example, see Figure 3 As shown, the elastic element 3 may be a gasket, so that the elastic element 3 extends axially and radially tapers along at least a portion of the rear end 32 toward the front end 31, and the inner diameter of the rear end 32 is larger than the outer diameter of the front end 31, so that axial elastic deformation can be generated. Specifically, the gasket may have an expansion section 33, a flat contraction section 35, and a tapered section 34, the expansion section 33 radially expands to form the rear end 32 in an annular plane, the flat contraction section 35 radially contracts to form the front end 31 in an annular plane, and the tapered section 34 is respectively connected between the inner diameter of the expansion section 33 and the outer diameter of the flat contraction section 35, and extends axially from the expansion section 33 to the flat contraction section 35 and radially tapers, so that the inner diameter of the expansion section 33 is larger than the outer diameter of the flat contraction section 35. Among them, the expansion section 33 and the flat contraction section 35 help to evenly transmit the force. Furthermore, the gasket is specifically made of an elastic material, so when subjected to axial compression, it can provide a positive force of elastic deformation of the material in the opposite directions to the abutment between the front end 31 and the rear end 32 .

[0031] The fixing element 4 is also sleeved on the outer portion of the sleeve section 21 of the adapter 2 and abuts against the front end 31 of the elastic element 3. Therefore, the elastic element 3 is located between the second side 12 of the fixing seat 1 and the fixing element 4. In this way, the fixing element 4 provides the adapter 2 with axial limitation relative to the fixing seat 1, and allows the adapter 2 to move radially relative to the fixing seat 1. Among them, the spacing between the fixing element 4 and the second side 12 of the fixing seat 1 is preset to be smaller than the length between the front end 31 and the rear end 32 of the elastic element 3 in the unstressed state, so that the elastic element 3 is compressed when placed therein and provides a moderate positive force to both ends. For example, the fixing element 4 can be a buckle ring (such as a C-ring) or a nut with a threaded inner ring for locking. Among them, if the fixing element 4 is a buckle ring, the buffer section 23 can also form an annular groove corresponding to the fixing buckle ring, which is suitable for the buckle ring to be tightened at a predetermined position without generating undesired axial movement.

[0032] The abutting gasket 5 is disposed in the fixing seat 1 and sleeved on the buffer section 23 of the adapter seat 2. One side of the abutting gasket 5 has a convex portion 51. The convex portion 51 protrudes through the through hole 121 and abuts against the elastic element 3. Figure 3 As shown, the convex portion 51 may be a ring-shaped tubular structure with a fixed diameter, extending axially through the through hole 121 and directly contacting the flattened section 35 of the gasket, thereby transmitting the external force to the fixing element 4 through the flattened section 35 along the axial direction, and then the adapter 2 bears the force from the abutting gasket 5. The convex portion 51 of the abutting gasket 5 and other parts of the abutting gasket 5 may be integrally formed or non-integrally arranged, such as Figure 3 The example shown is an integral molding, but this is not limiting.

[0033] The spring 6 is sleeved on the buffer section 23, and the two ends thereof respectively abut against the other side of the abutting gasket 5 and the axial limiting portion 24 of the adapter 2. Thus, when the adapter 2 is inserted into the accommodating space 13 of the fixing seat 1, the spring 6 is compressed and generates pre-stress because the length between the two ends is less than the equilibrium length without external force. Figure 3 As shown, by making the spring 6 respectively abut the axial limit portion 24 of the adapter 2 and the abutting gasket 5, and as mentioned above, the abutting gasket 5 transmits the force via the convex portion 51, and the pre-pressure of the spring 6 is transmitted to the fixing element 4 through the flattened section 35 of the gasket, so that both ends of the spring 6 apply force to the adapter 2 to achieve force balance, so as to avoid excessive radial sliding resistance due to excessive pre-pressure of the spring 6.

[0034] For details, please refer to Figure 3As shown, the elastic element 3 and the fixing element 4 are respectively sleeved on the sleeve section 21 of the adapter 2, and the abutting gasket 5 and the spring 6 are respectively sleeved on the buffer section 23. As can be seen from the above, the elastic element 3 of the utility model is compressed at both ends of the abutment and provides positive force outward through both ends, so that friction is generated between the rear end 32 and the second side 12 of the fixing seat 1; thereby, the adapter 2 can move radially relative to each other in the through hole 121, such as vertically moving and fixedly hovering at any position in the activity space. Among them, in the above embodiment, for example, the relative spacing between the protrusion 51 of the abutting gasket 5 and the fixing member 4 can also be adjusted and controlled, and it can be designed to cooperate with the structure of the gasket (such as the length of the tapered section 34) to further adjust and control the size of the radial sliding resistance according to needs.

[0035] Please refer to this Figure 4 and Figure 5 As shown, the inner diameter of the through hole 121 is larger than the outer diameter of the sleeve section 21, and there is a radial spacing between the protrusion 51 of the abutting gasket 5 and the inner diameter of the through hole 121, so that the adapter seat 2 can move radially relative to each other in the through hole 121, such as moving vertically and fixedly hovering at any position in the activity space, and at the same time allow the adapter seat 2 to be slightly tilted to compensate for the radial tolerance and possible uneven force.

[0036] Thus, in the decompression structure of the floating fixed seat of the joint of the utility model, the configuration of the elastic element 3, the abutting gasket 5 and the fixing element 4 between the fixing seat 1 and the adapter seat 2 makes the positive force more stable, not only allowing the adapter seat 2 to hover at any position in the activity space during radial relative movement, but also avoiding the problem of difficulty in radial relative movement caused by excessive pre-pressure.

[0037] The above description has been a detailed description of the utility model, and the above description is only a preferred embodiment of the utility model, which should not limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made based on the utility model should still fall within the scope of the patent of the utility model.
