[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] As shown in the figure, this utility model discloses an airtight fixture for a liquid-cooled plate, including a main connector 1, an air pipe connector 2 installed on the top of the main connector 1, a claw mounting groove 11 provided on the outer side of the lower end of the main connector 1, a claw retaining ring 12 provided on the claw mounting groove 11, the upper ends of several claws 3 being engaged with the claw retaining ring 12, a locking ring 4 being fitted on the outer side of the main connector 1 and the claws 3, a sealing groove 31 being provided on the outer side of the upper end of the claws 3, and a sealing ring 5 being installed in the sealing groove 31.

[0028] When the locking ring 4 is at the top, the pawl 3 is in the loose state. At this time, the water nozzle is manually inserted to the bottom of the main connector 1, and then the locking ring 4 is moved downwards. Then the locking ring 4 is rotated to lock the pawl 3.

[0029] Specifically, the upper end of the claw 3 is provided with a groove 34, the height of which is greater than that of the claw retaining ring 12. The claw retaining ring 12 is located inside the groove 34 to prevent the claw 3 from falling off the claw retaining ring 12.

[0030] In one embodiment of the present invention, the top of the main connector 1 is provided with a fixing ring mounting part 13, and a fixing ring 6 is installed at the fixing ring mounting part 13. The outer diameter of the fixing ring 6 is larger than the outer diameter of the locking ring 4, and the distance between the lower end of the fixing ring 6 and the claw mounting groove 11 is smaller than the height of the locking ring 4.

[0031] In one embodiment of this utility model, the claw 3 has an arc-shaped structure. A locking ring support 32 is provided on the outer lower end of the claw 3, and a main connector support 33 is provided on the inner lower end of the claw 3. The distance between the top of the claw 3 and the locking ring support 32 is less than the height of the locking ring 4. The height design of the locking ring 4 ensures that, regardless of its position, it covers a portion of both the claw 3 and the main connector 1, keeping them connected and preventing separation.

[0032] In one embodiment of this utility model, the main connector 1 is provided with a limiting screw mounting groove 14, one end of the limiting screw 7 is installed in the limiting screw mounting groove 14, and the upper end of the locking ring 4 is provided with a limiting groove 41. The limiting groove 41 is vertically arranged and the upper end of the limiting groove 41 is open. When not locked, the limiting screw 7 is located in the limiting groove 41.

[0033] When the chuck 3 is in the open state, the limit screw 7 prevents the locking ring 4 from rotating, ensuring that the chuck 3 is always in the open state.

[0034] In one embodiment of the present invention, the locking ring 4 is further provided with a horizontal groove 42 and an arc groove 43. The horizontal groove 42 connects the limiting groove 41 and the arc groove 43, and one end of the arc groove 43 is connected to the top of the locking ring 4.

[0035] When locking is required, the locking ring 4 is moved, the limiting groove 41 moves, and then the limiting screw 7 moves from the horizontal groove 42 and the arc groove 43 to the top of the locking ring 4 in sequence. Then the locking ring 4 is rotated to complete the locking. At this time, the upper end of the locking ring 4 is blocked by the limiting screw 7, and the pawl 3 is always in the locked state.

[0036] In one embodiment of this utility model, the lower end of the main connector 1 is provided with two sealing ring mounting grooves 15, and sealing rings 8 are installed in the sealing ring mounting grooves 15. The upper end of the water nozzle is installed at the lower end of the main connector 1.

[0037] The sealing ring 28 serves a sealing function.

[0038] In one embodiment of this utility model, when the locking ring 4 is located at the lower end, the front end of the main connector support 33 is located at the water nozzle groove at the water nozzle, thereby locking the water nozzle. Here, a water nozzle groove needs to be opened on the outer ring of the water nozzle.

[0039] In one embodiment of this utility model, the fixing ring 6 is threadedly connected to the fixing ring mounting part 13.

[0040] In one embodiment of this invention, three claws 3 are provided and distributed circumferentially. This invention uses three claws 3 to lock the water nozzle.

[0041] This invention features a good self-locking mechanism, easy-to-replace chucks, and low cost.

[0042] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
