Description

Joint floating fixed seat pressure relief structure

A joint floating fixed seat pressure relief structure, especially a joint floating fixed seat pressure relief structure that can reduce the radial sliding resistance of the floating joint.

As server computing performance continues to improve, the heat generated by the computing units inside it 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 an additional heat dissipation module to dissipate heat for each server. Therefore, water cooling is currently used to provide heat dissipation for each server in the server cabinet. Since the server has precise electronic parts, 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. 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, currently, the quick connectors are 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.

In addition, in order to save space inside the server cabinet, some businesses have omitted the use of guide posts and guide seats, so they have specially provided a fixing seat for radial offset correction for the radial setting of the two mutually connected male and female connectors, and set 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, it can provide radial offset correction when the male and female connectors are assembled. However, since the fixing seat and the adapter are clamped relative to each other through two gaskets corresponding to the fixing seat, Under the action of the two gaskets, a positive force is formed between the fixed seat and the adapter, so that the adapter can be suspended at a fixed position in the radial activity space relative to the fixed seat after radial movement. However, when the positive force generated by the two gaskets on the fixed seat is too large, it will cause too much resistance and make 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 maintain its position after movement. Therefore, how to improve the lack of knowledge is the primary goal of people in this skill.

Therefore, in order to effectively solve the above-mentioned problems, the main purpose of this invention is to provide a joint floating fixed seat pressure relief structure that can reduce the radial sliding resistance of the floating joint, thereby effectively controlling the positive force of the adapter relative to the fixed seat, reducing the resistance of the adapter relative to the fixed seat, so as to effectively control and maintain the position of the adapter relative to the fixed seat after movement; and, the size of the radial sliding resistance can be selectively controlled, and the adapter is allowed to tilt slightly.

To achieve the above-mentioned purpose, the invention provides a joint floating fixed seat pressure relief structure, which includes: a fixed seat, an adapter seat, an elastic element, a fixed element, a backing pad and a spring; the fixed seat has a first side and a second side, and has an internal accommodation space located between the first side and the second side, the first side is open, and the second side has a through hole, which is connected to the accommodation space; the adapter seat has a joint section and a sleeve section, and a buffer section is provided between the joint section and the sleeve section, and an axial limit portion is formed at the connection between the joint section and the buffer section, and the sleeve section is penetrated through the accommodation space of the fixed seat and is connected to the fixed seat. The through hole of the fixed seat protrudes outward; the elastic element is sleeved on the sleeve section, and has a front end and a rear end, and the rear end abuts against the second side of the fixed seat; the fixed element is sleeved on the sleeve section and abuts against the front end of the elastic element, providing the adapter seat with axial limit relative to the fixed seat, and allowing the adapter seat to move relative to the fixed seat in the radial direction; the abutting pad is arranged in the fixed seat and sleeved on the buffer section of the adapter seat, and one side of the abutting pad has a convex portion abutting against the elastic element through the through hole; the spring is sleeved on the buffer section, and its two ends abut against the other side of the abutting pad and the axial limit portion of the adapter seat respectively.

Through the setting of the decompression structure of the floating fixed seat of the joint of this invention, the spring can be effectively controlled to stably provide an appropriate positive force between the adapter and the fixed seat, avoiding excessive sliding resistance or too small positive force in the radial movement between the two, so as to ensure that the adapter can be suspended at any position in the activity space.

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 Figure 1 of this case, which is a three-dimensional exploded view of an embodiment of the present invention's floating fixed seat pressure relief structure; Figure 2 is a combined cross-sectional view of an embodiment of the present invention's floating fixed seat pressure relief structure; Figure 3 is a partially enlarged schematic view of the combined cross-sectional view of the present invention's floating fixed seat pressure relief structure; Figure 4 is an actuation schematic view of an embodiment of the present invention's floating fixed seat pressure relief structure; and Figure 5 is an actuation schematic view of an embodiment of the present invention's floating fixed seat pressure relief structure.

As shown in Figures 1 and 2 of this case, an embodiment of the joint floating fixing seat pressure relief structure of the present invention includes: a fixing seat 1, an adapter seat 2, an elastic element 3, a fixing element 4, a supporting gasket 5 and a spring 6.

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 forms 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 having a through hole 121. The through hole 121 is connected to the containing space 13.

The two ends of the adapter 2 have a joint section 22 and a sleeve section 21, respectively, and a buffer section 23 is provided between the joint section 22 and the sleeve section 21, and an axial limit portion 24 is formed at the connection between the joint section 22 and the buffer section 23. The sleeve section 21 is passed 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 arranged in the through hole 121. The joint section 22 of the adapter 2 can be connected with a male connector 7, and the joint section 22 can also be connected with other structures or components without limitation, or the joint section 22 can extend another structure to be connected with other components for use.

The elastic element 3 is sleeved on the outside 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 seat 1. In detail, the elastic element 3 can generate a positive force by axially compressing the front end 31 and the rear end 32; for example: a spring, a gasket or a spring, etc., but the present case is not limited to this.

For example, please refer to FIG. 3 , the elastic element 3 may be a gasket, so that the elastic element 3 extends axially and radially contracts 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 , thereby generating axial elastic deformation. Specifically, the gasket may have an expansion section 33, a contraction section 35, and a gradual contraction section 34. The expansion section 33 expands radially to form the rear end 32 in the shape of an annular plane, the contraction section 35 contracts radially to form the front end 31 in the shape of an annular plane, and the gradual contraction section 34 connects the inner diameter of the expansion section 33 and the outer diameter of the contraction section 35, and extends axially from the expansion section 33 to the contraction section 35 and gradually contracts radially, so that the inner diameter of the expansion section 33 is larger than the outer diameter of the contraction section 35. The expansion section 33 and the 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 for elastic deformation of the material in the opposite direction of the abutment between the front end 31 and the rear end 32.

The fixing element 4 is also sleeved on the outside 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. The distance 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 a non-stressed 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 retaining ring (e.g., a C-shaped ring) or a ring-shaped nut with threads inside for locking. If the fixing element 4 is a retaining ring, the buffer section 23 can also form an annular groove corresponding to the fixed retaining ring, which is suitable for tightening the retaining ring at a predetermined position without causing undesirable axial movement.

The abutting gasket 5 is arranged 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, which protrudes through the through hole 121 and abuts against the elastic element 3. For example, as shown in FIG. 3, the convex portion 51 can be a ring-shaped structure with a fixed diameter, extending axially through the through hole 121 and directly contacting the flattened section 35 of the gasket, so as to transmit the external force axially to the fixing element 4 through the flattened section 35, and then the adapter seat 2 bears the force from the abutting gasket 5. The protrusion 51 of the abutting gasket 5 and other parts of the abutting gasket 5 can be formed in an integral manner or in a non-integrated manner. As shown in FIG. 3 , they are formed in an integral manner, but this is not limited to the present invention.

The spring 6 is sleeved on the buffer section 23, and the two ends thereof respectively abut against the other side of the abutting pad 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 base 1, the spring 6 is compressed to generate a pre-stress because the length between the two ends is limited to be less than the equilibrium length without external force. In this invention, as shown in FIG. 3, the spring 6 is respectively abutted against the axial limit portion 24 of the adapter 2 and the abutting gasket 5, and as mentioned above, the abutting gasket 5 is subjected to force through the convex portion 51, and the preload force of the spring 6 is transmitted to the fixing element 4 through the flattened section 35 of the gasket. In this way, 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 preload force of the spring 6.

Specifically, as shown in FIG. 3 , the elastic element 3 and the fixing element 4 are respectively sleeved on the sleeve section 21 of the adapter 2, and the abutting pad 5 and the spring 6 are respectively sleeved on the buffer section 23. As described above, the elastic element 3 of the present invention is compressed at the two ends of the abutment and provides positive force outward through the two 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 suspended at any position in the activity space. Among them, in the above-mentioned embodiment, for example, the relative distance between the protrusion 51 of the pad 5 and the fixing element 4 can be adjusted and controlled, and the relative distance between the protrusion 51 and the fixing element 4 can be matched with the structure of the pad (such as the length of the tapered section 34) to further adjust and control the size of the radial sliding resistance as needed.

Thus, with reference to Figures 4 and 5, 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 pad 5 and the inner diameter of the through hole 121, so that the adapter 2 can move radially relative to the through hole 121, such as vertically moving and fixedly suspended at any position in the activity space, and at the same time allow the adapter 2 to be slightly tilted to compensate for the radial tolerance and possible uneven force.

Thus, in the joint floating fixed seat pressure relief structure of the invention, the elastic element 3, the abutting gasket 5 and the fixing element 4 are arranged between the fixing seat 1 and the adapter seat 2, so that the positive force is more stable, not only the adapter seat 2 can be suspended at any position in the activity space when it moves relative to the radial direction, but also the problem of difficulty in relative radial movement caused by excessive pre-stress is avoided.

The above has been a detailed description of this creation, but what is described above is only a preferred embodiment of this creation and should not limit the scope of implementation of this creation. That is, all equal changes and modifications made according to the application scope of this creation should still fall within the scope of patent coverage of this creation.
