Description

Technical Field

[0001] The utility model relates to a joint floating fixed seat friction reducing structure, in particular to a joint floating fixed seat friction reducing structure in which an adapter seat and the inner side of a fixed seat perform relative radial movement by rolling to reduce radial friction. Background Art

[0002] Currently, with the improvement of server computing performance, the heat generated by the internal computing units also increases. In addition, multiple servers are installed in a server cabinet at the same time, and the space between each server is very narrow. It is impossible to set up additional heat dissipation modules to dissipate heat for each server one by one. Therefore, the industry has used water cooling 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. 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 tolerance in the radial direction when they are assembled, in order to facilitate the rapid correction of the radial tolerance of the two quick connectors, at least one guide column is 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.

[0003] In addition, in order to save space inside the server cabinet, some industry players have omitted the use of guide columns and guide seats. Therefore, they have specially provided a fixing seat for radial offset correction for the radial offset of two mutually docked 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 seat are connected to the fixing seat through a spring and two gaskets to increase the sliding contact area, the two gaskets have the effect of clamping the fixing seat relative to each other, so that the adapter seat can be maintained in a fixed position relative to the fixing seat after radial movement.

[0004] However, the preload of the spring causes excessive friction between the gasket and the fixed seat due to the positive force of the spring, making it difficult for the adapter to slide radially and unable to keep the adapter in a fixed position relative to the fixed seat. Therefore, how to improve the conventional defects has become the primary goal of people in this field. Utility Model Content

DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1 It is a three-dimensional exploded view of the utility model; Figure 2 It is a combined cross-sectional view of the utility model; Figure 5A , Figure 5B As shown in the figure, the utility model provides a joint floating fixed seat friction reduction structure, comprising: a fixed seat 1, an adapter seat 2, a fixed element 4, a rolling member 5 and a spring 7.

[0028] 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 has 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 with a through hole 121. The through hole 121 is connected to the accommodating space 13.

[0029] The two ends of the adapter 2 are respectively provided with a joint section 21 and a sleeve section 22, and a buffer section 23 is provided between the joint section 21 and the sleeve section 22. The inside of the adapter 2 is provided with a passage 24 connecting the joint section 21 and the sleeve section 22. The adapter 2 passes through the accommodation space 13 of the fixed seat 1 through the sleeve section 22, and protrudes outward from the through hole 121 of the fixed seat 1. The outer diameter of the joint section 21 is larger than the outer diameter of the buffer section 23, so that an axial stopper 25 is formed at the connection between the two. The inner diameter of the through hole 121 is larger than the outer diameter of the sleeve section 22.

[0030] For example, the joint section 21 of the adapter 2 can be connected to a male connector 8. In addition, the joint section 21 can also be connected to other structures or components, or extended to be connected to other structures for use, and the present invention is not limited thereto.

[0031] The fixing element 4 is sleeved on the sleeve section 22 of the adapter 2 and is located outside the second side 12 of the fixing seat 1 to provide axial limitation of the adapter 2 relative to the fixing seat 1 and allow the adapter 2 to move radially relative to the fixing seat 1; wherein the fixing element 4 can be a buckle, a nut or a C-shaped buckle, etc., and correspondingly, a corresponding annular groove or thread for fixation can be formed on the sleeve section 22.

[0032] In this embodiment, the rolling member 5 and the spring 7 are both disposed in the accommodating space 13 of the fixing seat 1 and sleeved on the buffer section 23 of the adapter seat 2 .

[0033] The rolling member 5 is disposed in the accommodation space of the second side 12 of the fixing seat 1. Specifically, the at least one rolling member 5 can also be disposed on either or both of the inner and outer surfaces of the second side 12. However, in this embodiment, Figure 2 As shown, the rolling member 5 is disposed on the inner surface of the second side 12 and can roll on the surface of the second side 12 of the fixing seat 1 .

[0034] At this time, one end of the spring 7 abuts against the axial limit portion 25 of the adapter seat 2. The other end of the spring 7 abuts against the rolling member 5. In addition, since the length between the axial limit portion 25 and the second side 12 of the fixed seat 1 is less than the equilibrium length between the two ends of the spring 7 without external force, the spring 7 is compressed in the accommodating space 13 to generate pre-pressure, and respectively applies positive forces in opposite directions to the axial limit portion 25 of the adapter seat 2 and the rolling member 5 or the inner sliding gasket 6. In this way, the rolling member 5 is interposed between the other end of the spring 7 and the second side 12 of the fixed seat 1, and by rolling relative to the second side 12, the radial friction force generated by the positive force applied by the other end of the spring 12 on the fixed seat 1 is reduced.

[0035] The rolling member 5 may include a retaining frame 51 and a plurality of rolling units 52. Specifically, the rolling units 52 may be any structure that can roll relative to a plane, such as rollers, balls, etc. In this embodiment, the rolling units 52 are shown as balls. In addition, the retaining frame 51 is provided with a plurality of fitting holes 511 suitable for accommodating the rolling units 52, so that the rolling units 52 can roll in the fitting holes 511. The rolling units 52 also protrude toward the outside of the fitting holes 511, so that the protruding parts are in contact with the second side 12, so that when subjected to radial external forces, the rolling units 52 can roll, thereby driving the rolling member 5 to move radially.

[0036] And, if Figure 1 and Figure 2As shown, in this embodiment, the engaging holes 511 can be recessed inwardly on the side surface of the retainer 51 opposite to the inner surface of the second side 12, without penetrating the rolling member 5. Therefore, the rolling units 52 can make the rolling member 5 radially roll relative to the second side 12 of the fixing seat 1 (the inner surface of the second side 12 in this embodiment). At the same time, the other side surface of the retainer 51 opposite to the second side 12 (i.e., abutting against the other end of the spring 7) is an annular plane. Thereby, when the positive force of the spring 7 applies force to the annular plane of the retainer 51, the rolling member 5 abuts against the second side 12 relative to the second side 12 through the rolling units 52, so that the rolling member 5 can achieve relative radial movement through the rolling of the rolling units 52. Furthermore, the radial friction force generated by the positive force of the spring 7 acting on the fixing seat 1 is reduced by rolling.

[0037] It should be noted that, although the rolling member 5 is shown in the accommodating space 13 of the fixing seat 1 in this embodiment, it is not limited to this. In another variation, the rolling member 5 is selected to be arranged outside the fixing seat 1 together with the sliding gasket 3 and the fixing element 4, and is sleeved on the sleeve section 22 of the adapter seat 2 (such as Figure 5A One difference is that the other end of the spring 7 directly abuts against the inner surface of the second side 12 of the fixing seat 2, or abuts against the rolling member 5 disposed therein. In other variations, not only is there a rolling member 5 in the accommodating space 13 of the fixing seat 1, but another rolling member 5 is also disposed between the sliding pad 3 and the outer surface of the second side 12 of the fixing seat 1 (e.g. Figure 5B shown).

[0038] Figure 3 and Figure 4 Another three-dimensional exploded view and another combined cross-sectional view of the friction reducing structure of the joint floating fixing seat of the utility model are shown in the figure. As shown in the figure, the rolling member 5 is still arranged on the inner surface of the second side 12 at this time.

[0039] Among them, Figure 3 and Figure 4 As shown, the engaging holes 51 of the rolling member 5 can also directly penetrate between the two side surfaces of the retaining frame 51, so that the rolling units 52 can partially protrude from one or both sides of the rolling member 5. In this case, the sliding structure 5 also includes a sliding gasket 6, which is adjacently disposed on the other side surface of the retaining frame 51 opposite to the second side 12. Figure 4 As shown, when the sliding member 5 is disposed on the inner surface of the second side 12 as in this example, the sliding gasket 6 is also disposed between the sliding member 5 and the spring 7, so that the other end of the spring 7 will abut against the sliding gasket 6 of the rolling member 5, and then contact the protruding parts of the rolling units 52, and can cause the rolling units 52 to undergo the above-mentioned radial rolling.

[0040] Correspondingly, if Figure 4 and Figure 5A As shown, the rolling member 5 is disposed on one of the inner and outer surfaces of the second side 12, and the other surface of the second side 12 of the fixing seat 1 may also be provided with a sliding pad 3 adjacent to the second side 12, which is sleeved on the sleeve section 22 of the adapter seat 2 to provide buffering during radial movement. Figure 4 As shown in FIG. 1 , the positive force from the spring 7 will be transmitted to the sliding pad 3 through the adapter seat 2 and then through the fixed element 4, so that the sliding pad 6 and the sliding pad 3 are respectively subjected to positive forces from both sides. The sliding pad 6 is directly subjected to the positive force of the spring 7, and is tightly pressed against one side of the rolling member 5 in the direction of the second side 12 of the fixed seat 1, and the other side of the rolling member 5 is pressed against the inner surface of the second side 12 of the fixed seat 1. At the same time, the sliding pad 3 is also subjected to the positive force of the spring 7, and is tightly pressed against the outer surface of the second side 12. In this way, the sliding pad 6 and the sliding pad 3 both produce a clamping effect in the direction of the second side 12 of the fixed seat 1.

[0041] See also Figure 6 , Figure 7 , is a schematic diagram of the operation of the decompression structure of the floating fixing seat of the utility model. Figure 4 As shown in the embodiment, the utility model sets the rolling member 5 in contact with the inner surface of the second side 12 of the fixing seat 1, so that the rolling member 5 can move (roll) radially relative to the inner surface of the second side 12 of the fixing seat 1 in a rolling manner, thereby reducing the radial friction. In this way, it is possible to avoid the problem of excessive radial friction or even wear of parts caused by the positive force applied by the spring 7 on the fixing seat 1, not only improving the smoothness of the relative displacement between the fixing seat 1 and the adapter 2, but also keeping the adapter 2 stably suspended at the final position after the radial rolling displacement.

[0042] In this way, the radial friction between the adapter and the fixed seat is improved, and the radial friction between the sliding gasket and the sliding gasket relative to the fixed seat is larger due to the positive force of the spring during the radial movement between the adapter and the fixed seat, which makes the radial offset operation between the adapter and the fixed seat difficult to perform.

[0043] Therefore, the rolling member 5 of the present invention moves radially (rolls) relative to the second side 12 of the fixing seat 1 in a rolling manner to reduce the friction between the spring 7 or the sliding gasket 6 (and / or the sliding gasket 3) and the fixing seat 1. And the adapter 2 can be suspended at any radially offset position after radial displacement. In this way, various defects derived from the excessive friction caused by the positive force of the existing spring are improved.
