Problems solved by technology
[0002] Among the cooling methods of PC case, water cooling is the most effective form. In the water cooling system, a large number of connecting pipes and sealing joints are required. The sealing performance of the sealing joints is related to the service life and stability of the water cooling system. The existing technology A structure in which an O-ring is used to cooperate with structural parts to compress the O-ring to achieve the sealing effect of the sealed joint has several disadvantages: first, the connection tightness of the structural parts is very high, and the structure When the components are used in the PC case, it is inevitable to be affected by the temperature and produce a certain deformation. This deformation will affect the tightness of the connection to a certain extent; It is easy to age and lose a certain degree of elasticity if it is in a single compressed state for a long time in the environment, which will also lead to a decrease in sealing performance
However, the invention patent only changed the shape of the sealing surface, and there was no change in the sealing mechanism so that it could not be applied to the water cooling system

Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0023] like figure 1 The illustrated embodiment of the present invention comprises a first connecting body 1 having a first through hole 1-1 axially penetrating through it; a second connecting body 2 having a second through hole axially penetrating through the second connecting body 2. Hole 2-2, the second connecting body 2 is connected to one end of the first connecting body 1; the first sealing ring 3, the first sealing ring 3 is nested in the other end of the first connecting body 1, and also includes the second sealing Ring 4, one end of the second sealing ring 4 is provided with a first sleeve section 4-1 that is interference fit with the first through hole 1-1, and the other end is provided with a first sleeve section 4-1 that is interference fit with the second through hole 2-2. For the two socket sections 4-2, the radial cross-sectional diameter at a...

The invention provides a novel seal joint which comprises a second seal ring. A first sleeve-joint section, which is in interference fit with a first through hole, is arranged at one end of the second seal ring. A second sleeve-joint section, which is in interference fit with a second through hole, is arranged at the other end of the second seal ring. The diameters of the radial sections of all positions of the first sleeve-joint section are smaller than that of the maximal radial section of the second sleeve-joint section. The two sealing ways of interference fit and end sealing are adopted, the sealing performance of the novel seal joint is further improved by introducing the interference fit way, and the risk that since the connection compactness is reduced, the sealing performance is linearly reduced is reduced.
