Description

Technical Field

[0001] This utility model relates to a quick connector for a medium pipeline, belonging to the field of liquid cooling heat dissipation technology. Background Technology

[0002] With the rapid development of computer technology, data center servers are being deployed in high-density and even ultra-high-density configurations to meet the demands of high-performance computing services. During server operation, a significant amount of heat is generated, requiring cooling to ensure normal operation. Liquid-cooled servers utilize a liquid cooling loop, which connects to the server rack's distributor via quick-connect couplings or other types of connectors. This allows for uninterrupted heat exchange between the server's liquid cooling loop and the distributor's loop, facilitating heat exchange between the server's liquid cooling system and the external environment. However, existing quick-connect couplings for media pipelines are inconvenient for the insertion and disconnection of male and female connectors, and accidental contact can lead to loosening, compromising safety during use. Utility Model Content

[0003] The purpose of this invention is to provide a quick connector for media pipelines. This quick connector facilitates the insertion and separation of male and female connectors and can prevent loosening between the male and female connectors due to accidental contact, thereby improving safety during use.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a quick connector for a media pipeline, comprising a female sleeve, a support rod axially disposed within the female sleeve, and a male sleeve located on the outer side of the upper end of the female sleeve and capable of being axially inserted downward into the female sleeve. A support plate with several through holes is installed between the lower end of the support rod and the inner wall of the female sleeve. The upper end of the support rod has a radially outward flange, and the inner wall of the upper part of the female sleeve has a radially inward first inner flange. A floating ring that mates with the lower end face of the male sleeve is sealed between the first inner flange and the flange of the support rod. A female spring is provided between the floating ring, which can move axially, and the support plate. A stop ring, a male spring, and a floating block that mates with the upper end face of the support rod are arranged sequentially along the axial direction inside the male sleeve. A second inner flange that runs radially inward is provided on the inner wall of the lower end of the male sleeve, on which the stop ring is fixedly installed. The side wall of the second inner flange is sealed with the floating block that can move axially.

[0005] The outer wall of the male sleeve is provided with an annular flange extending radially outward. The lower end face of this annular flange is configured as a first inclined surface extending radially outward at the upper end. The female sleeve is respectively equipped with a first locking block and a second locking block that can move radially. One end of each of the first locking block and the second locking block is embedded in the female sleeve, and a groove is formed on the lower surface of the other end of each. The upper part of the end of the first locking block and the second locking block embedded in the female sleeve is provided with a second plane parallel to the first inclined surface. The upper end of a rotating block rotatably mounted on the female sleeve is correspondingly embedded in the groove on the lower surface of the first locking block and the second locking block. The lower ends of the two rotating blocks are connected to the female sleeve by a horizontally arranged spring, so that the end faces of the first locking block and the second locking block embedded in the female sleeve can be flush with the side wall of the first inner flange.

[0006] The following are further improvements to the above technical solution:

[0007] 1. In the above scheme, the first card block and the second card block, as well as the two rotating blocks, are arranged in an axisymmetric manner.

[0008] 2. In the above scheme, a rubber coating layer is provided on the outer side of the rotating block.

[0009] 3. In the above scheme, the rotating block is rotatably mounted on the female head sleeve via a pin.

[0010] 4. In the above scheme, the floating ring and the first inner flange are sealed together by at least one first sealing ring embedded in the side wall of the first inner flange, the floating ring and the flange portion of the support rod are sealed together by at least one second sealing ring embedded in the outer side wall of the flange portion, and the floating block and the second inner flange are sealed together by at least one third sealing ring embedded in the outer side wall of the floating block.

[0011] 5. In the above scheme, there are two of each of the first sealing ring, the second sealing ring, and the third sealing ring, which are distributed at intervals along the axial direction.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] This utility model discloses a quick connector for a media pipeline. The male sleeve has an annular flange extending radially outward on its outer wall. The lower end face of this annular flange is configured as a first inclined surface extending radially outward at its upper end. The female sleeve, located above the first inner flange, has a first locking block and a second locking block, each capable of radial movement. One end of each locking block is embedded in the female sleeve, and the lower surface of the other end has a groove. The upper part of the end of each locking block embedded in the female sleeve has a second plane parallel to the first inclined surface. The connector is rotatably mounted... The upper end of the rotating block on the female sleeve is correspondingly embedded in the groove on the lower surface of the first and second locking blocks. A horizontally arranged spring connects the lower end of each of the two rotating blocks to the female sleeve, so that the end face of the first and second locking blocks embedded in the female sleeve can be flush with the side wall of the first inner flange.

[0019] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0020] Example 1: A quick connector for a media pipeline includes a female sleeve 1, a support rod 2 axially disposed within the female sleeve 1, and a male sleeve 3 located on the outer side of the upper end of the female sleeve 1 and capable of being axially inserted downward into the female sleeve 1. A support plate 6 with several through holes 61 is installed between the lower end of the support rod 2 and the inner wall of the female sleeve 1. The upper end of the support rod 2 has a radially outward flange 5, and the inner wall of the upper part of the female sleeve 1 has a radially inward first inner flange 7. This first inner flange 7 and the support rod 2... A floating ring 8 that mates with the lower end face of the male sleeve 3 is sealed between the flange portions 5. A female spring 9 is provided between the axially movable floating ring 8 and the support plate 6. A stop ring 12, a male spring 13, and a floating block 14 that mates with the upper end face of the support rod 2 are sequentially arranged axially inside the male sleeve 3. A second inner flange 15 that runs radially inward is provided on the inner wall of the lower end of the male sleeve 3, on which the stop ring 12 is fixedly installed. The side wall of this second inner flange 15 is sealed with the axially movable floating block 14.

[0021] The outer wall of the male sleeve 3 is provided with an annular flange 17 extending radially outward. The lower end face of this annular flange 17 is configured as a first inclined surface 181 extending radially outward at the upper end. The female sleeve 1, located above the first inner flange 7, is respectively equipped with a first locking block 191 and a second locking block 192, each capable of radial movement. One end of each of the first locking block 191 and the second locking block 192 is embedded in the female sleeve 1, and a groove 20 is formed on the lower surface of the other end of each. The upper part of one end of the 92 embedded in the female sleeve 1 is provided with a second plane 182 parallel to the first inclined surface 181. The upper end of a rotating block 21 rotatably mounted on the female sleeve 1 is correspondingly embedded in the groove 20 on the lower surface of the first locking block 191 and the second locking block 192. The lower end of each of the two rotating blocks 21 is connected to the female sleeve 1 by a horizontally arranged spring 22, so that the end face of the first locking block 191 and the second locking block 192 embedded in the female sleeve 1 can be flush with the side wall of the first inner flange 7.

[0022] When the male and female connectors are inserted into each other, the floating block inside the male connector sleeve moves upward and compresses the male connector spring, thus opening the flow channel after the male and female connectors are inserted.

[0023] When the male and female connectors are separated, the lower ends of the two rotating blocks need to be pressed inward simultaneously to make the corresponding locking blocks exit the area above the annular flange. After the floating blocks are reset, they seal their respective flow channels through the sealing ring under the action of the spring.

[0024] The first locking block 191 and the second locking block 192, as well as the two rotating blocks 21, are arranged symmetrically on the axis; a rubber coating layer 23 is provided on the outer side of the rotating block 21.

[0025] The floating ring 8 and the first inner flange 7 are sealed together by at least one first sealing ring 10 embedded in the side wall of the first inner flange 7. The floating ring 8 and the flange portion 5 of the support rod 2 are sealed together by at least one second sealing ring 11 embedded in the outer side wall of the flange portion 5. The floating block 14 and the second inner flange 15 are sealed together by at least one third sealing ring 16 embedded in the outer side wall of the floating block 14. Two of each of the first sealing ring 10, the second sealing ring 11 and the third sealing ring 16 are provided and are spaced apart along the axial direction.

[0026] The floating ring 8 has a guide portion 81 extending axially downward on its lower end surface and outside the female head spring 9. This guide portion 81 slides in contact with the inner wall of the female head sleeve 1.

[0027] Example 2: A quick connector for a media pipeline includes a female sleeve 1, a support rod 2 axially disposed within the female sleeve 1, and a male sleeve 3 located on the outer side of the upper end of the female sleeve 1 and capable of being axially inserted downward into the female sleeve 1. A support plate 6 with several through holes 61 is installed between the lower end of the support rod 2 and the inner wall of the female sleeve 1. The upper end of the support rod 2 has a radially outward flange 5, and the inner wall of the upper part of the female sleeve 1 has a radially inward first inner flange 7. This first inner flange 7 and the support rod 2... A floating ring 8 that mates with the lower end face of the male sleeve 3 is sealed between the flange portions 5. A female spring 9 is provided between the axially movable floating ring 8 and the support plate 6. A stop ring 12, a male spring 13, and a floating block 14 that mates with the upper end face of the support rod 2 are sequentially arranged axially inside the male sleeve 3. A second inner flange 15 that runs radially inward is provided on the inner wall of the lower end of the male sleeve 3, on which the stop ring 12 is fixedly installed. The side wall of this second inner flange 15 is sealed with the axially movable floating block 14.

[0028] The outer wall of the male sleeve 3 is provided with an annular flange 17 extending radially outward. The lower end face of this annular flange 17 is configured as a first inclined surface 181 extending radially outward at the upper end. The female sleeve 1, located above the first inner flange 7, is respectively equipped with a first locking block 191 and a second locking block 192, each capable of radial movement. One end of each of the first locking block 191 and the second locking block 192 is embedded in the female sleeve 1, and a groove 20 is formed on the lower surface of the other end of each. The upper part of one end of the 92 embedded in the female sleeve 1 is provided with a second plane 182 parallel to the first inclined surface 181. The upper end of a rotating block 21 rotatably mounted on the female sleeve 1 is correspondingly embedded in the groove 20 on the lower surface of the first locking block 191 and the second locking block 192. The lower end of each of the two rotating blocks 21 is connected to the female sleeve 1 by a horizontally arranged spring 22, so that the end face of the first locking block 191 and the second locking block 192 embedded in the female sleeve 1 can be flush with the side wall of the first inner flange 7.

[0029] When the male and female connectors are inserted into each other and the flow channel is open, the annular flange moves to the position of the low locking block, so that its lower surface overlaps with the upper surface of the annular flange to achieve a stop, avoiding loosening between the male and female connectors due to accidental contact and improving safety during use.

[0030] The aforementioned rotating block 21 is rotatably mounted on the female sleeve 1 via a pin 24; the upper end face of the aforementioned floating block 14 has a limiting part 141 that extends axially upward and slides in contact with the inner wall of the male sleeve 3.

[0031] The working principle of this utility model is as follows:

[0032] When in use, the opposite ends of the male and female sleeves are connected to the fluid pipeline.

[0033] When the male and female heads are separated:

[0034] The floating block inside the male sleeve moves to the second inner flange under the action of the male spring and seals the inner flow channel of the male head through the third sealing ring. The floating ring inside the female sleeve moves to the space between the upper flange and the first inner flange under the action of the female spring and seals the inner flow channel of the female head through the first sealing ring and the second sealing ring.

[0035] The lower ends of the two rotating blocks rotate away from the male sleeve under the action of the spring, so that their upper ends drive the corresponding first and second locking blocks to move radially inward to the innermost end of their stroke. At this time, the end face of one end of the first and second locking blocks is flush with the side wall of the first inner flange.

[0036] When the male and female connectors are plugged into each other:

[0037] The male sleeve moves downward and enters the female sleeve, causing the outer surface of the male sleeve to slide into contact with the side wall of the first inner flange inside the female sleeve. The downward-moving male sleeve pushes the floating ring inside the female sleeve to move downward and compress the female spring. The floating block inside the male sleeve moves upward relative to the male sleeve and compresses the male spring under the push of the upper end face of the fixed support rod. At this time, the flow channels inside the male and female sleeves are connected and interconnected.

[0038] As the annular flange on the male sleeve moves down with the male sleeve until its first inclined surface contacts the second inclined surface on the first and second locking blocks; the annular flange continues to move down, simultaneously pushing the first and second locking blocks, which can only move radially, to move outward, causing the upper end of the corresponding rotating block to rotate outward and the lower end to rotate inward, compressing the spring.

[0039] When the annular flange moves below the first and second locking blocks, the first and second locking blocks lose the restraint of the annular flange and reset inward under the action of the spring, thereby allowing the lower surfaces of the first and second locking blocks to overlap with the upper surface of the annular flange to stop the male sleeve.

[0040] When the connected male and female connectors are separated:

[0041] Simultaneously press the lower ends of the two rotating blocks inward so that the upper ends of the two rotating blocks respectively drive the first and second locking blocks to move outward and exit the area above the annular flange. The male sleeve, which has lost its stop position, moves upward under the action of the female spring, so that the male sleeve can be pulled out from the female sleeve. Then, release the lower ends of the two rotating blocks so that the upper ends of the rotating blocks drive the first and second locking blocks to return to the innermost end of their stroke under the action of the spring.

[0042] After the male and female springs lose their compressive force, they reset. Under the action of the reset male spring, the floating block inside the male sleeve moves back to the second inner flange and re-seals the inner flow channel of the male head through the third sealing ring. Under the action of the reset female spring, the floating ring inside the female sleeve moves back between the upper flange and the first inner flange and re-seals the inner flow channel of the female head through the first and second sealing rings.

[0043] When using the quick connectors for the aforementioned media pipelines, in addition to ensuring the flow path is open after the male and female connectors are plugged in, they can also seal the flow path of each connector after they are separated. This facilitates the plugging and unplugging of the male and female connectors and prevents loosening between them due to accidental contact, thus improving safety during use.

[0044] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
