In this embodiment, the base 20 is a plastic nut, the seal ring groove 24 on the base 20 has a concave-convex structure, which is an anti-disengagement structure, so as to ensure that the seal ring 30 is not easily disengaged after being assembled, and the plastic nut is adopted for fixing, so as to prevent the cooling liquid from rusting after flowing.

It should be noted that the plastic nut needs to ensure tightening torque and needs necessary strength.

Referring to fig. 9, the assembly and use of a seal structure 100 according to the present invention will be further described. The rubber hose 300 leading to the single-machine controller is firstly connected to the upper end of the connecting pipe 10, the upper end of the connecting pipe 10 is the end close to the upper bottom surface 121 of the base 12, and at the moment, the rubber hose 300 leading to the single-machine controller is abutted against the upper bottom surface 12 of the base 12. The metal plate 200 is provided with a metal plate through hole 201, and then the connecting pipe 10 assembled with the rubber pipe 300 leading to the single-machine controller passes through the metal plate through hole 201 and penetrates through the metal plate 200, so that one end of the connecting pipe 10 enters the single-machine controller. At this time, the lower bottom surface 122 of the base 12 abuts against the metal plate 200, and the sealing rubber ring 13 abuts against and presses the metal plate 200. Further, the seal ring 30 is accommodated in the seal ring groove 24, the base 20 passes through the connecting pipe 10 through the threaded hole 21, and the thread 112 of the screw 11 is screwed with the threaded hole 21 on the base 20 until the lower surface 23 of the base 20 is attached to the metal plate 200. At this time, the seal ring 30 is pressed against the other surface of the metal plate 200. Finally, the rubber tube 400 of the radiator is sleeved on the other side of the connecting tube 10, namely, the side close to the base 20, and the rubber tube 400 of the radiator is abutted against the upper surface 22 of the base 20. After the assembly is completed, the cooling liquid or the cooling wind, etc. may be introduced into the through hole 111 of the connection pipe 10 through the rubber hose 400 of the heat sink, and introduced into the rubber hose 300 of the single-machine controller, so that the cooling liquid or the cooling wind is delivered from the sealing structure 100 to the electronic device to be heat-dissipated.

The base 20 is screwed up on the connecting pipe 10, so that the sheet metal 200 is clamped tightly, the base 12 and the sheet metal pass through hole 201 are in interference fit through the sealing rubber ring 13, and the base 20 and the sheet metal pass through hole 201 are in interference fit through the sealing ring 30. Therefore, the effect of sealing the vehicle is achieved, and meanwhile, the width of the sealing ring is considered, so that a good noise isolation effect is achieved.

The utility model discloses still provide the seal structure of another kind of embodiment, it is for planting the welding bolt on panel beating 200, then places the sealing washer between base 12 and panel beating 200 to screw up with base 20, rely on the pressure of base 12 and panel beating 200, guarantee sealing performance. This scheme adopts the mode of panel beating plant welding nut.

At present, a sealing structure leading from the outside of an automobile to the inside of the automobile basically adopts a mode of sealing and gluing a plug by a wire harness, but the mode can not ensure the performance requirement of waterproof seven levels, and when the sealing structure is applied to a rubber water pipe, the water pipe can deform to a certain extent, so that the matching part of the plug and the water pipe can not form effective sealing, and the requirement of waterproof performance seven levels can not be met. This kind of problem can effectually be avoided to this design, and this design relies on the tightening force of plastic nut to produce the interference fit of sealing washer and plastic substrate, panel beating face, forms effectual sealed effect, verifies through the test that can reach seven grades of waterproof requirements and the effect of making an uproar that separates, has designed concave-convex structure on plastic substrate simultaneously, can guarantee that the sealing washer can not fall out after the assembly, and simultaneously, the nut adopts plastic products, has avoided rusty influence.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
