Description

Joint floating fixing seat structure

A joint floating fixed seat structure, in particular a joint floating fixed seat structure that can provide correction for the offset before the butt joint of two non-coaxial joints to prevent excessive wear during the joint.

Currently, with the improvement of server computing performance, the heat generated by the internal computing units has also increased. In addition, multiple servers are installed in a server cabinet at the same time, and the space between each server is very narrow, so 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 precise 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 installed on the server (active side) and the server cabinet (fixed side) for docking, so that the water pipes on the active side and the fixed side can be quickly connected or separated. Because the radial tolerance of the male and female connectors will be small when assembled, in order to facilitate the rapid correction of the radial tolerance of the two quick connectors, they will be placed near the fixed side. At least one guide post is arranged beside the position where the female connector is arranged on the fixed side (server cabinet), and a guide seat is arranged beside the position where the male connector is arranged on the movable side (server) at the position corresponding to the guide post, and the guide seat has a guide hole. When assembling the male and female connectors, the guide post is first inserted into the guide hole of the guide seat. Under the guidance of the guide post and the guide seat, the two quick connectors with radial tolerance are first guided until the two quick connectors are close to the coaxial center, and then the two connectors are aligned and connected in series.

Since the space inside the server cabinet is quite narrow, guide posts and guide seats must be correspondingly arranged at each joint between the male and female connectors to calibrate the radial offset of the two connectors. Therefore, the installation of guide posts and guide seats takes up a lot of space inside the server cabinet.

In addition, in order to save space inside the server cabinet, some businesses want to omit the use of guide posts and guide seats. Therefore, they specifically control the tolerance accuracy of the radial offset of the two mutually connected male and female connectors, and set a bevel at the position where the inner hole of the female connector first contacts the male connector when the bevel contacts the male connector. When the bevel contacts the male connector, the two guide the male connector and the female connector to correct the slight radial offset by friction, thereby increasing the smoothness of the connection between the two connectors. Although the use of guide posts and guide seats can be omitted in this way, the following problems will still arise. Due to the increased requirements for the matching accuracy of various items, It will increase the assembly time and thus the manufacturing cost. Moreover, when using male and female connectors directly as offset correction parts, the front end of the male connector is very important for the sealing between the male and female connectors. If the front end of the male connector is damaged by impact or excessive wear, it will cause the sealing between the joints inside the female connector and the sealing elements inside the female connector to be insufficient and unable to close the water valve between the two, thus causing the sealing between the male and female connectors to be poor and leaking. Therefore, how to improve the lack of knowledge is the primary goal of people in this craft.

Therefore, in order to effectively solve the above problems, the main purpose of this invention is to provide a joint floating fixed seat structure with radial offset correction function, thereby correcting two quick joints with combined tolerance in the radial direction, and smoothly correcting the radial eccentricity between the two joints to provide a combined joint floating fixed seat structure.

To achieve the above-mentioned purpose, the invention provides a joint floating fixing seat structure, which includes: a fixing seat, an adapter seat, and a fixing element; the fixing seat has a first side and a second side on both sides, and a receiving space is formed inside the fixing seat, the first side is open, and the receiving space is located between the first side and the second side, the second side is a closed side with a through hole, and the through hole is connected to the receiving space; the adapter seat has a guide part and a connecting part, and one end of the guide part is open. The guide part has a receiving space inside, and the two ends of the connecting part have a sleeve end and a joint end, and the connecting part has a flow channel inside, which is connected with the receiving space. The adapter passes through the connecting part to penetrate the accommodating space and protrudes outward from the through hole of the fixed seat. The fixing element is sleeved on the outside of the connecting part of the adapter to provide axial limitation of the adapter relative to the fixed seat, and allows the adapter to move radially relative to the fixed seat.

The receiving space of the adapter seat can accommodate a male connector, and one end of the male connector is connected to the joint end of the adapter seat. When the male connector and a female connector are axially connected, the guiding slope of the guide part of the adapter seat first makes initial contact with the female connector, and the female connector continues to be guided by the guiding slope to enter the receiving space. At the same time, the adapter seat also produces radial displacement. When the female connector completely enters the receiving space, the male and female connectors are close to the same axis, and the two begin to engage axially.

This invention makes it possible to correct radial offset and perform axial butt jointing without the need for additional guide posts and guide seats on male and female joints.

The above-mentioned purpose of this invention and its structural and functional characteristics will be explained according to the preferred embodiments of the attached drawings.

Please refer to Figures 1 and 2, which are the three-dimensional decomposition and assembly cross-sectional views of the first embodiment of the joint floating fixing seat structure of this invention. As shown in the figure, the joint floating fixing seat structure includes: a fixing seat 1, an adapter seat 2, a first gasket 3, and a fixing element 4.

The fixing base 1 has a first side 11 and a second side 12 on opposite sides. The fixing base 1 has a containing space 13 inside. The containing 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 containing space 13. The second side 12 is a closed side with a through hole 121. The through hole 121 is connected to the containing space 13.

The adapter 2 has a guide portion 21 and a connecting portion 22. One end of the guide portion 21 is open and has a guide slope 211 inside the open end edge. The guide portion 21 has a receiving space 212 inside. The guide portion 21 and the connecting portion 22 can be formed in an integral or non-integrated manner. This embodiment is implemented in an integral manner but is not limited thereto. The connecting portion 22 is formed by extending the other end of the guide portion 21.

The two ends of the pipe section 22 respectively have a sleeve end 221 and a joint end 222, the joint end 222 is connected to the aforementioned guide section 21, and the interior of the pipe section 22 has a flow channel 225, the flow channel 225 is interconnected with the aforementioned receiving space 212, the adapter 2 is penetrated into the accommodating space 13 through the pipe section 22, and then protrudes outward from the through hole 121 of the fixing seat 1, and the joint end 222 is attached to the inner surface of the second side 12 through an abutment surface 223; the sleeve end 221 of the pipe section 22 is provided for the adapter 2 to be connected with other external pipelines, and the pipeline (not shown in the figure) can be directly sleeved on the outside of the sleeve end 221 to be combined with the adapter 2. The inner diameter of the through hole 121 of the fixing seat 1 is larger than the outer diameter of the sleeve end 221 of the connecting pipe portion 22 of the adapter 2, so that the adapter 2 has a radial displacement relative to the fixing seat 1 and can move relatively.

The receiving space 212 of the guide portion 21 can provide a male connector 5 to be arranged inside the receiving space 212, and one end of the male connector 5 is assembled corresponding to the joint end 222. The joint end 222 of this embodiment has an internal thread 2221 arranged inside, and an external thread 51 is arranged outside the end of the male connector 5 corresponding to the joint end 222. The male connector 5 is screwed with the internal thread 2221 of the joint end 222 through the external thread 51 to be combined with the adapter 2.

The first gasket 3 is sleeved on the outside of the connecting pipe 22 of the adapter 2, and one side is attached to the outer surface of the second side 12 of the fixing seat 1. The outside of the connecting pipe 22 has an annular groove 224. The fixing element 4 is sleeved on the outside of the connecting pipe 22 of the adapter 2 for positioning. The fixing element 4 can be a nut or a buckle ring or other element with a locking function. This embodiment uses a buckle ring as an illustrative embodiment, but it is not limited to this. The fixing element 4 is clamped in the annular groove 224 and fits with one side of the first gasket 3. Together with the first gasket 3, it provides the axial limit of the adapter 2 relative to the fixing seat 1 and limits the adapter 2 to only radial relative movement relative to the fixing seat 1.

Please refer to Figures 3 and 4, which are three-dimensional exploded and assembled cross-sectional views of another embodiment of the adapter of the floating fixing seat structure of the present invention. As shown in the figure, the guide portion 21 and the connecting portion 22 of the adapter 2 are not integrally formed. The guide portion 21 and the connecting portion 22 are two independent components combined with each other. The end of the guide portion 21 without the guide slope 211 is provided with a connecting hole 213. The joint end 222 of the connecting portion 22 has a flange 2222, and the outer diameter of the flange 2222 is larger than the connecting hole 213. The connecting portion 22 is penetrated by the aforementioned connecting hole 213, and the flange 2222 is clamped at the connecting hole 213 to form an axial limit.

The male connector 5 enters the guide portion 21 through the receiving space 212 of the guide portion 21, and is fixed to the connecting portion 22 by engaging with the internal thread 2221 provided on the connecting portion 22 through the external thread 51 provided on one end of the male connector 5.

Please refer to Figures 5A and 5B, which are combined cross-sectional views of the second embodiment of the floating fixing seat structure of the present invention. As shown in the figure, this embodiment is partially identical to the first embodiment, so it will not be described here in detail. However, the difference between this embodiment and the first embodiment is that there is a buffer section 24 between the sleeve end 221 and the joint end 222 of the pipe portion 22 of the adapter 2, and a spring 6 and a second gasket 7 are sleeved on the outside of the buffer section 24, and the two ends of the spring 6 abut against the inner surface of the second side 12 of the fixing seat 1 and one side surface of the second gasket 7, respectively.

The buffer section 24 is provided to provide the adapter 2 with an axial expansion margin relative to the fixed base 1, and the spring 6 is provided to provide an axial positive force and friction force to ensure smoother radial movement of the adapter 2 relative to the fixed base 1. The second gasket 7 is also provided to increase the smoothness of the axial sliding of the adapter 2 relative to the fixed base 1.

Please refer to Figures 6, 7, 8, and 9, which are schematic diagrams of the operation of the floating fixing seat structure of the present invention. As shown in the figure, the left side of Figures 6, 7, 8, and 9 is the fixed side. This embodiment uses a server cabinet 8 as an example. The components on the fixed side (server cabinet 8) are the female connector 9 and other components installed on the server cabinet 8. This embodiment Only the female connector 9 is used for illustration, and the other parts are not shown or described in detail. In addition, the unit assembly located on the right side of Figures 6, 7, 8, and 9 is the movable side relative to the server cabinet 8, which is implemented by a server case (box) 10 that slides with the server cabinet 8. The floating fixing seat structure of this invention is set on the movable side server cabinet. The present embodiment is particularly for explaining the operation of the various components of the floating fixing seat structure, and other components on the server housing 10 are not further explained and shown. As shown in the figure, the floating fixing seat structure of the present invention is installed on the server housing 10 through the fixing seat 1, and the female connector 9 on the fixing side (server cabinet 8) is to be connected. For the axial docking operation, firstly, since the female connector 9 and the male connector 5 disposed on the movable side (server housing 10) are not on the same axial track, there is a slight radial offset between the two. Therefore, before the two (male and female connectors 5 and 9) are axially docked, the radial offset between the two must be corrected to within the error range so that docking can be performed.

First, the guide portion 21 of the adapter 2 is used to guide the radial offset correction work relative to the female connector 9 before the joint. The female connector 9 contacts the guide bevel 211 of the guide portion 21 through the outer edge of its end. When the adapter 2 continues to displace axially toward the female connector 9, the adapter 2 is guided by the guide bevel 211 and approaches the female connector 9 axially. Then, the adapter 2 will move radially due to the guidance of the guide bevel 211. When the female connector 9 completely enters the receiving space 212, the radial offset between the male connector 5 and the female connector 9 disposed in the receiving space 212 is also corrected to be close to zero. Finally, the male connector 5 is inserted into the female connector 9 and the two complete the docking operation.

This invention mainly uses the adapter 2 to replace the direct contact between the male connector 5 and the female connector 9 for the correction of radial offset, which can avoid the wear caused by the male connector 5 and the female connector 9 when they are connected, so that the sealing between the joint points of the male connector 5 and the female connector 9 and the sealing elements of the male and female connectors 5 and 9 can be kept intact, and ensure that the water valve installed between the two is indeed sealed without leakage.

In addition, the offset correction amount of the female connector 9 and the male connector 5 can be adjusted and set through the design ratio of the guide slope 211 of the guide portion 21 of the adapter 2 and the radial relative movement range between the fixed base 1 and the adapter 2.

This invention eliminates the traditional method of setting guide posts and guide seats to correct the radial offset of the male and female connectors 5 and 9, which not only saves a lot of component installation costs, but also improves the problem of excessive space crowding between server cabinets and server shells.
