[0034] The working principle of the utility model is as follows:

[0035] In use, the male head sleeve and the female head sleeve are respectively connected with fluid pipelines at the opposite ends thereof;

[0036] When the male head and the female head are separated:

[0037] The floating block in the male head sleeve is moved to the second inner flange under the action of the male head spring and realizes sealing of the inner flow channel of the male head through the third sealing ring, and the floating ring in the female head sleeve is moved to the position between the upper flange part and the first inner flange under the action of the female head spring and realizes sealing of the inner flow channel of the female head through the first sealing ring and the second sealing ring;

[0038] The pressing part of the clamping ring moves away from the female sleeve under the action of the first spring so that the clamping part thereon is at the innermost end of its stroke, and the lower end of the rotating block rotates away from the female sleeve under the action of the second spring so that the upper end thereof drives the movable block to move inwardly along the radial direction to the innermost end of its stroke. At this time, the second inclined surface on the pressing part of the clamping ring is flush with the third inclined surface on the rotating block, and the end faces of the respective ends of the clamping ring and the rotating block are flush with the side wall of the first inner flange.

[0039] When the male head and the female head are inserted into each other:

[0040] The male sleeve moves downward into the female sleeve and makes the outer side surface of the male sleeve in sliding contact with the side wall of the first inner flange in the female sleeve. The downwardly moving male sleeve pushes the floating ring in the female sleeve downward and compresses the female spring, and the floating block in the male sleeve moves upward relative to the male sleeve under the pushing of the end face of the upper end of the fixed support rod and compresses the male spring. At this time, the respective flow channels in the male head and the female head are connected and communicate with each other.

[0041] When the protruding part on the male sleeve moves downward until the first inclined surface thereon is in contact with the flush second inclined surface and third inclined surface, the protruding part continues to move downward while pushing the respective pressing part and movable block of the clamping ring that can only move along the radial direction to move outward, so that the pressing part of the clamping ring moves toward the female sleeve to compress the first spring and the lower end of the outwardly rotating rotating block rotates inwardly to compress the second spring.

[0042] When the protruding part moves below the pressing part and movable block of the clamping ring, the pressing part and movable block of the clamping ring lose the restriction of the protruding part and are respectively reset inwardly under the action of the first spring and the second spring, so that the lower surfaces of the respective pressing part and movable block of the clamping ring are lapped with the upper surface of the protruding part to achieve the stop of the male sleeve.

[0043] When the inserted male head and female head are separated from each other:

[0044] The pressing part of the clamping ring needs to be pushed toward the female sleeve while the lower end of the rotating block is pressed toward the female sleeve so that the protruding part of the clamping ring moves outwardly out of the area above the protruding part and the upper end of the rotating block simultaneously drives the movable block to move outwardly out of the area above the protruding part. The male sleeve that loses the stop moves upward under the action of the female spring, so that the male sleeve can be pulled out of the female sleeve. Then, the pressing part of the clamping ring and the lower end of the rotating block are released so that the protruding part of the clamping ring and the rotating block are respectively reset to the innermost end of their strokes under the action of the first spring and the second spring.

[0045] After the male spring and the female spring lose the extrusion force respectively, the floating block in the male sleeve moves back to the second inner flange under the action of the reset male spring and re-seals the male inner flow channel through the third sealing ring, and the floating ring in the female sleeve moves back to the space between the upper flange and the first inner flange under the action of the reset female spring and re-seals the female inner flow channel through the first sealing ring and the second sealing ring.

[0046] When the positioning mechanism of the liquid cooling connector and the liquid cooling connector are used, on the basis of realizing the flow channel conduction after the male connector and the female connector are inserted, the flow channels of the male connector and the female connector can be sealed after the male connector and the female connector are separated, the mutual insertion and separation between the male connector and the female connector are facilitated, the separation of the male connector and the female connector can be realized only when the pressing part on the clasp and the rotating block are pressed at the same time, the loosening between the male connector and the female connector caused by unilateral mis-touch is effectively avoided, and the safety and stability during use are improved.

[0047] The above embodiments are only for illustrating the technical concept and characteristics of the utility model, the purpose is to enable the person skilled in the art to understand the content of the utility model and implement it, and cannot limit the protection scope of the utility model. Any equivalent change or modification according to the spirit and essence of the utility model shall be covered within the protection scope of the utility model.
