Description
Technical Field

[0002] Traditional natural and air cooling methods are far from meeting the cooling needs of electronic devices. Liquid cooling technology has become the mainstream cooling method for electronic devices. Whether it's personal computers or large-scale data centers, they are increasingly adopting efficient liquid cooling technology to replace inefficient air cooling. Liquid-cooled servers contain a liquid cooling loop. This loop connects to the liquid cooler in the server rack via quick-connect couplings or other types of connectors, allowing for heat exchange between the server's liquid cooling loop and the external environment. Traditional connectors, being exposed to the outside, are prone to malfunctions and safety issues in complex operating environments. Utility Model Content

[0021] The aforementioned movable block 12 and the inner protrusion 6 are slidably engaged by at least one set of guide protrusions 281 and guide grooves 282.
[0022] The aforementioned movable block 12 is installed on the upper part of the outer sleeve 1; the horizontal part 31 of the aforementioned L-shaped movable block 3 is embedded in the groove 8 opened on the upper part of the outer sleeve 1.
[0023] The aforementioned inner protrusion 6 and outer protrusion 7 each extend radially; the aforementioned receiving groove 10 is formed on the side surface of the horizontal part 31 of the L-shaped movable block 3 facing the inner wall of the slide groove 8.
[0024] Working principle: During use, the opposite ends of the inner sleeve and outer sleeve are connected to the fluid pipeline. When the inner and outer sleeves separate: The floating block inside the inner sleeve moves to the lower end of the inner sleeve under the action of the return spring and seals with the inner sleeve to seal the flow channel inside the inner sleeve. The floating ring inside the outer sleeve moves to the upper end of the support rod under the action of the return spring and seals with the outer sleeve and the support rod respectively to seal the flow channel inside the outer sleeve. The vertical part of the L-shaped movable block moves away from the outer sleeve under the action of the first elastic element, so that the inner convex part on it is located at the innermost end of its stroke. At the same time, the lower end of the rotating block rotates away from the outer sleeve under the action of the third elastic element, so that its upper end drives the movable block to move radially inward to the innermost end of its stroke. At this time, the upper end surface of the inner convex part on the L-shaped movable block is flush with the upper end surface of the end of the movable block that is embedded in the outer sleeve.
[0025] When the inner and outer sleeves are interlocked: The inner sleeve moves downward and enters the outer sleeve. The downward movement of the inner sleeve pushes the floating ring in the outer sleeve to move downward and compress the return spring. The floating block in the inner sleeve moves upward relative to the inner sleeve under the push of the fixed support rod upper end face and compresses the return spring. At this time, the flow channels in the inner and outer sleeves are connected and interconnected. As the inner sleeve moves downward, the protrusion on the inner sleeve moves downward until its lower end face contacts the upper end face of the inner protrusion on the L-shaped movable block and the upper end face of the end of the movable block that is embedded in the outer sleeve; the protrusion continues to move downward with the inner sleeve, and at the same time pushes the horizontal part of the L-shaped movable block, which can only move radially, and the movable block to move outward, so that the vertical part of the L-shaped movable block moves towards the outer sleeve to squeeze the first elastic element and the lower end of the rotating block that rotates outward at its upper end rotates inward to compress the third elastic element; When the outer protrusion on the inner sleeve moves below the inner protrusion and the movable block on the L-shaped movable block, the vertical part of the L-shaped movable block and the movable block, no longer restricted by the outer protrusion on the inner sleeve, reset inward under the action of the first elastic element and the third elastic element, so that the lower surface of the inner protrusion on the L-shaped movable block and the movable block respectively overlap with the upper surface of the outer protrusion on the inner sleeve to stop the inner sleeve.
[0026] When it is necessary to separate the connected outer sleeve and inner sleeve again: The vertical part of the L-shaped movable block needs to be pushed towards the outer sleeve while the lower end of the rotating block is pressed towards the outer sleeve. This causes the inner convex part on the horizontal part of the L-shaped movable block to move outward and exit the area above the outer convex part on the inner sleeve. At the same time, the upper end of the rotating block drives the movable block to move outward and exit the area above the outer convex part on the inner sleeve. The inner sleeve, which has lost its stop position, moves upward under the action of the return spring, so that the inner sleeve can be pulled out from the outer sleeve. Then, the vertical part of the L-shaped movable block and the lower end of the rotating block are released, so that the inner convex part on the horizontal part of the L-shaped movable block and the movable block that moves with the rotating block are reset to the innermost end of their stroke under the action of the first elastic element and the third elastic element, respectively. After the return springs in the outer sleeve and inner sleeve lose their compressive force, they reset. Under the action of the reset spring, the floating block in the inner sleeve moves back to the lower end of the inner sleeve and seals with the inner sleeve to re-seal the flow channel inside the inner sleeve. Under the action of the reset spring, the floating ring in the outer sleeve moves back to the upper end of the support rod and seals with the outer sleeve and support rod respectively to re-seal the flow channel inside the outer sleeve.
[0027] During the reciprocating insertion and separation process of the outer sleeve and inner sleeve, the horizontal part of the L-shaped movable block reciprocates within the receiving groove of the outer sleeve, allowing the inner convex part to move radially inward and outward. During this process, the pin block and the second elastic element provided between the two side surfaces of the horizontal part of the L-shaped movable block and the inner wall of the slide groove provide precise guidance for the horizontal part of the L-shaped movable block, preventing it from shifting its position. Furthermore, both the pin block and the second elastic element can be easily and quickly assembled inside the outer sleeve, avoiding the risks caused by exposed small parts in complex usage environments and improving the convenience and safety of use.
[0028] During the assembly of the outer sleeve and the rotating block, the positioning tube is first passed through the positioning hole on the rotating block. Then, the positioning pins that can be compressibly installed at both ends of the positioning tube cooperate with the positioning grooves on the two side walls of the mounting groove on the outer sleeve to achieve the rotational installation of the rotating block. All mounting components are located inside the outer sleeve, avoiding the risks caused by the exposure of small parts in complex use environments and improving the convenience and safety of use.
[0029] When using the above-mentioned liquid-cooled pipe joint, it can not only seal the internal flow channels of the inner and outer sleeves in the separated state, but also facilitate the insertion connection and conduction between the inner and outer sleeves. It can also effectively avoid the loosening of the connection between the inner and outer sleeves due to accidental contact in the insertion state. Furthermore, it can facilitate the assembly of various components on the inner and outer sleeves and ensure the stability of the connection between components. It can also avoid the risks caused by the exposure of small components in complex use environments, thereby improving the convenience and safety of use.

They should not be construed as limiting the scope of protection of this utility model.
