Since liquid cooling can realize high-power heat dissipation compared with air cooling, has the advantage of good heat dissipation effect, therefore, it is a development trend to adopt liquid cooling to cool the server single boards in the cabinet. In the existing liquid cooling heat dissipation cabinet, liquid cooling medium is supplied to each server single board through a liquid distribution pipe, and then the liquid cooling medium after heat exchange in each server single board is recovered through a liquid collection pipe. Specifically, the liquid inlet of each server single board is communicated with the liquid distribution pipe through a joint assembly, and the liquid outlet of each server single board is also communicated with the liquid collection pipe through a joint assembly. Usually, the joint assembly comprises two pluggable plug-in ends, one of the two plug-in ends is communicated with the server single board, and the other plug-in end is communicated with the liquid distribution pipe or the liquid collection pipe.
[0003] When the valve core in the plug-in end communicated with the liquid distribution pipe or the liquid collection pipe fails, if the plug-in end with the failed valve core is not plugged with the other plug-in end, the liquid cooling medium in the liquid distribution pipe or the liquid collection pipe will leak from the liquid outlet of the plug-in end, causing liquid leakage and liquid spraying. The liquid cooling medium flowing to or splashing on the server single board may cause short circuit of the server single board, and even cause the occurrence of the board burning phenomenon.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.
[0023] REFERENCE Figures 1-5The utility model provides a joint splash -proof mechanism, including joint body 1, the both ends of joint body 1 are first joint end and second joint end respectively, the outside fixed connection of first joint end is fixed seat 2, the outside sliding sleeve of second joint end is provided with sealing sleeve pipe 3, the inside of the side away from fixed seat 2 of sealing sleeve pipe 3 is provided with splash -proof door 4, and the both ends of splash -proof door 4 are fixedly connected with the rotation of two rotating shafts 5, and the side wall of sealing sleeve pipe 3 is rotatably connected with two rotating shafts 5 respectively, and one rotating shaft 5 is connected with the output end of connecting rod transmission structure through the side wall of sealing sleeve pipe 3, and the outer wall of sealing sleeve pipe 3 is fixedly connected with the protective housing 6 of covering the connecting rod transmission structure, and the top of protective housing 6 is provided with push block 7, and the input end of connecting rod transmission structure is rotatably connected with the fixed rod 8 fixedly connected at the bottom of push block 7, and the bottom of push block 7 is fixedly connected with the top of protective housing 6 between first reset spring 9.
[0024] In the embodiment, the connecting rod transmission structure includes a first connecting rod 10, a second connecting rod 11 and a third connecting rod 12. One end of the first connecting rod 10 is fixedly connected with one of the rotating shafts 5, and the other end is rotatably connected with one end of the second connecting rod 11. One end of the second connecting rod 11 away from the first connecting rod 10 is rotatably connected with one end of the third connecting rod 12. One end of the third connecting rod 12 away from the second connecting rod 11 is rotatably connected with the side wall of the sealing sleeve pipe 3 through a first fixed shaft 13. The middle part of the side of the third connecting rod 12 away from the sealing sleeve pipe 3 is fixedly connected with a second fixed shaft 14. The bottom of the fixed rod 8 is rotatably connected with the second fixed shaft 14 through a guide slot formed in the top of the protective housing 6. When the second joint end is not connected with the joint on the server single board, the push block 7 is located away from the protective housing 6 under the action of the first reset spring 9. At this time, the splash -proof door 4 is in a state perpendicular to the second joint end, so as to block the cooling liquid splashed from the second joint end. When the second joint end is connected with the joint on the server single board, the side wall of the server single board will first press the push block 7, so that the push block 7 moves towards the protective housing 6. At this time, the first reset spring 9 is gradually compressed. In the moving process of the push block 7, the third connecting rod 12 is pushed to rotate through the fixed rod 8. The second connecting rod 11 is driven to rotate by the third connecting rod 12. The first connecting rod 10 is driven to rotate by the second connecting rod 11. Finally, the splash -proof door 4 is driven to rotate to open the splash -proof door 4, so as to ensure that the second joint end can be smoothly connected with the joint on the server single board. When the second joint end is separated from the joint on the server single board, the push block 7 moves away from the protective housing 6 under the action of the first reset spring 9 after losing the pushing force. In turn, the third connecting rod 12, the second connecting rod 11 and the first connecting rod 10 are driven to rotate in the opposite direction when connected by the fixed rod 8. In turn, the splash -proof door 4 returns to the state perpendicular to the second joint end.
[0025] In the embodiment, the splash -proof door 4 is in an arcuate structure.
[0026] In the embodiment, the sealing sleeve 3 is fixedly connected with a drain pipe 15, which is in communication with the inside of the sealing sleeve 3, for draining the cooling liquid accidentally sprayed in the sealing sleeve 3, preventing the accumulation of the cooling liquid in the sealing sleeve 3.
[0027] In the embodiment, the fixing seat 2 is fixedly connected with a guide column 16 on each side of the joint body 1, and the sealing sleeve 3 is fixedly connected with a guide block 17 on each side of the upper portion, each guide block 17 is provided with a guide hole, and the two guide columns 16 are respectively inserted through the corresponding guide holes and are in sliding connection with the corresponding guide blocks 17. The guide column 16 and the guide block 17 can make the movement of the sealing sleeve 3 more stable.
[0028] In the embodiment, the two guide columns 16 are symmetrically arranged about the joint body 1.
[0029] In the embodiment, the second reset spring 18 is sleeved on the part of each guide column 16 between the fixing seat 2 and the guide block 17.
[0030] When the second joint end is not connected with the joint on the server single board, the second joint end is located in the inside of the sealing sleeve 3, when the second joint end is connected with the joint on the server single board, the push block 7 is pressed and opens the splash-proof door 4 through the connecting rod transmission structure, when the push block 7 is in complete contact with the protective shell 6, the pushing force is transmitted to the protective shell 6 and the sealing sleeve, the sealing sleeve moves to the direction of the fixing seat 2 under the pushing force and compresses the second reset spring 18, so that the second joint end extends outward to facilitate the connection with the joint on the server single board, when the second joint end is disconnected with the joint on the server single board, the sealing sleeve is reset under the action of the second reset spring 18 after losing the pushing force.
[0031] In the embodiment, the fixing seat 2 is fixedly connected with a limiting column 19 on each side of the joint body 1, and the sealing sleeve 3 is fixedly connected with a limiting plate 20 on each side of the bottom portion, each limiting plate 20 is provided with a limiting hole, and the two limiting columns 19 are respectively inserted through the corresponding limiting holes and are fixedly connected with a limiting clamp 21, and the limiting column 19 is in sliding connection with the limiting plate 20. The limiting clamp 21 can limit the limiting plate 20 and the sealing sleeve 3, preventing the sealing sleeve 3 from being separated from the joint body 1 due to a large moving distance.
[0032] In the embodiment, the two limiting columns 19 are symmetrically arranged about the joint body 1, and the two limiting columns 19 and the two guide columns 16 are respectively located on the two diagonal lines of the fixing seat.
[0033] The sealing sleeve 3 is provided with a splash-proof door 4, when the joint body 1 is not connected with other joints at the end far from the fixed base 2, the splash-proof door 4 is in a closed state, so even if the valve core in the joint body 1 fails, the splash-proof door 4 can also shield the liquid outlet end of the joint body 1, thereby preventing the cooling liquid from splashing on the server single board, and further providing reliable protection for the server single board.
[0034] The above is only the preferred embodiment of the present application, and does not limit the technical scope of the present application in any way, so any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical solution of the present application.
