[0023] Example

[0024] Reference Figs. 1-3 A hot-stamped insert water channel hole sealing device includes a sealing ring 1, a sealing ring 2, and a sealing ring 3, wherein: the outer ring of the sealing ring 1 is coaxially provided with the sealing ring 2, the inner ring of the sealing ring 1 is coaxially provided with the sealing ring 3, and the inner ring of the sealing ring 1 is coaxially provided with the support ring 4, so as to seal the water channel hole between two inserts through the sealing rings 1, 2, and 3;

[0025] Specifically, the support ring 4 is an elastic metal ring with an outward expansion force;

[0026] The circumferential surface of the sealing ring 2 is coaxially provided with a V-shaped groove 3 8, so that under the action of the support ring 4 and the groove, radial pressure is generated on the sealing ring 1 and the sealing ring 2, so that the circumferential surface of the sealing ring 2 is in close contact with the insert groove. At the same time, when in contact, the V-shaped groove 3 8 can be opened to increase the contact area at the connection between the two insert water channel holes, thereby better sealing the gap between the two insert water channel holes.

[0027] V-grooves 7 are coaxially provided on both sides of the connection between sealing ring 1 and sealing ring 2, so that when sealing ring 1 and sealing ring 2 are subjected to the extrusion force of the two insert end faces and the radial pressure between support ring 4 and insert groove, the V-grooves 7 can provide deformation space for V-grooves 6 and V-grooves 8.

[0028] In this embodiment, V-grooves 6 are coaxially formed on both ends of the sealing ring 1 so that when subjected to the extrusion force of the two insert end faces, the sealing ring 1 can expand to both sides through the V-grooves 6, thereby increasing the contact pressure between the sealing ring 1 and the two insert end faces and better sealing the water channel hole.

[0029] In this embodiment, a support ring 2 5 is coaxially arranged inside the sealing ring 2. The cross-section of the support ring 2 5 is V-shaped, so as to improve the strength of the sealing ring 2 2 through the support ring 2 5, and at the same time, it works with the insert groove to generate radial pressure on the sealing ring 2 2.

[0030] Specifically, support ring 25 is made of elastic metal ring and has an outward expansion force.

[0031] In this embodiment, the distance between the two openings of sealing ring 1 is greater than the distance between the two openings of sealing ring 2 and sealing ring 3; the distance between the two openings of sealing ring 2 is greater than the distance between the two openings of sealing ring 3, so as to provide multiple seals for the water channel hole.

[0032] The technical scheme of the utility model, or the technical scheme inspired by the technical scheme of the utility model, designs similar technical scheme, and achieves the above technical effect, and all falls into the protection range of the utility model.
