[0023] Exemplarily, the clip-on plate 1 is L-shaped, one end of the clip-on plate 1 is clipped to the air cooler, and the other end of the clip-on plate 1 is connected to the mounting plate 2. The clip-on plate 1 is used to fix the mounting plate 2 on the air cooler and avoid damaging the outer surface of the air cooler.

[0024] Exemplarily, there are two clip plates 1, and slots are provided on the mounting plate 2, which can be adjusted according to the positions of the two clip plates 1, thereby increasing the versatility of the leak-proof device of the present application.

[0025] Exemplarily, the sealing assembly 3 can safely wrap the screw plug inside under the action of the mounting plate 2, thereby preventing the screw plug from leaking.

[0026] In the embodiment of this application, Figure 1-3 As shown, the sealing assembly 3 further includes a glue injection pipe 33 ; the glue injection pipe 33 is connected to the outside of the external pressure head 31 and communicates with the inside of the external pressure head 31 .

[0027] Illustratively, the external pressure head 31 and the internal pressure head 32 can effectively seal the wire plug under the action of the mounting plate 2. Furthermore, the present application injects glue into the interior of the external pressure head 31 and the internal pressure head 32 through the glue injection pipe 33, which can further improve the sealing effect of the sealing assembly 3.

[0028] In the embodiment of this application, Figure 1-3 As shown, the sealing assembly 3 further includes a valve 34 , which is disposed on the glue injection pipe 33 .

[0029] Exemplarily, after the glue injection is completed, the operator closes the glue injection pipeline 33 through the valve 34 .

[0030] In the embodiment of this application, Figure 1-3 As shown, the external pressure head 31 includes a mounting seat 311 and a pressure head body 312; the mounting seat 311 is connected to the end of the pressure head body 312 away from the air cooler; a first cavity 4 and a second cavity 5 are provided on the pressure head body 312; the first cavity 4 is connected to the second cavity 5; the end of the internal pressure head 32 away from the air cooler is arranged in the first cavity 4, and the wire plug is arranged in the second cavity 5; a first conical surface 6 is provided on the pressure head body 312; the first conical surface 6 is in contact with the outer side surface of the internal pressure head 32; the end of the mounting seat 311 away from the air cooler is in contact with the mounting plate 2; the glue injection pipe 33 is connected to the first cavity 4.

When the pressure head body 312 moves toward the air cooler, the internal pressure head 32 can be squeezed inwardly under the action of the first conical surface 6, thereby enabling the wire plug to be sealed in the radial direction of the wire plug.

[0035] Exemplarily, the taper of the first conical surface 6 is greater than the taper of the second conical surface 7, and the first conical surface 6 fits the second conical surface 7. Under the action of the first conical surface 6, the second conical surface 7 can be squeezed, so that the sealing ring 321 is squeezed toward the wire plug, thereby enabling the wire plug to be sealed in the radial direction of the wire plug.
