Disclosure of Invention
An object of the utility model is to provide a metal base seal gasket to overcome the seal gasket sealing contact area among the prior art too big, too high and need great the holding power that adds of the required precision to sealed face, just can reach the defect of sealed effect.
In order to achieve the above object, the utility model provides a metal-based sealing gasket, include: the upper surface and the lower surface of the metal plate are sealing surfaces; a sealing hole provided in the metal plate; the nail passing hole is formed around the sealing hole and used for installing a fastening bolt; the plurality of closed glue lines are arranged on the two sealing surfaces of the metal plate in a mode of surrounding the sealing holes; the nail passing hole glue lines are closed and arranged on the two sealing surfaces of the metal plate in a mode of surrounding the nail passing holes; and the convex edge is arranged on the sealing surface of the metal plate and is wrapped in the glue line and the glue line passing through the nail hole.
Preferably, in the above technical solution, the positions of the glue lines on the two sealing surfaces are staggered with each other.
Preferably, in the above technical solution, the positions of the glue lines on the two sealing surfaces are aligned with each other.
Preferably, in the above technical scheme, the cross section of the rib is triangular, and the vertex angle is provided with an arc.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the utility model provides a glue the line and cross nail hole and glue the line, reduced the area of contact between the sealed face, make sealed required add the holding power and reduce to increase the life who seals gluey line.
2. The utility model provides a glue the line and cross and be equipped with the bead in the nail hole gluey line to increased the steadiness between gluey line and the sealed face, also prolonged seal gasket's life.

Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.
The first embodiment is as follows:
as shown in fig. 1 and 2, the metal-based gasket seal of this embodiment includes: the metal plate comprises a metal plate 1, a sealing hole 2, a nail passing hole 3, a glue line 4, a nail passing hole glue line 5 and a convex edge 6; the metal plate 1 is a substrate of the whole gasket, the upper surface and the lower surface of the metal plate are sealing surfaces, the thickness of the metal plate 1 is 10mm to 20mm, a sealing hole 2 is formed in the middle of the metal plate 1, and nail passing holes 3 for mounting fastening bolts are formed around the sealing hole 2; the glue lines 4 and the nail hole passing glue lines 5 are made of fluorine sulfide, the thickness of the glue lines is 1.5mm, the width of the glue lines is 3mm, a plurality of closed glue lines 4 are arranged on the two sealing surfaces of the metal plate 1 in a mode of surrounding the sealing holes 2, and a plurality of closed nail hole passing glue lines 5 are arranged on the two sealing surfaces of the metal plate 1 in a mode of surrounding the nail hole 3; the sealing surface of the metal plate 1 is also cast with a rib 6 which is just wrapped inside the glue line 4 and the glue line 5 passing through the nail hole.
With continued reference to fig. 2, the cross-section of the rib 6 is triangular, and the apex angles are ground into rounded corners; the positions of the glue lines on the two sealing surfaces are staggered.
Example two:
as shown in fig. 1 and 3, the metal-based gasket seal of this embodiment includes: the metal plate comprises a metal plate 1, a sealing hole 2, a nail passing hole 3, a glue line 4, a nail passing hole glue line 5 and a convex edge 6; the metal plate 1 is a substrate of the whole gasket, the upper surface and the lower surface of the metal plate are sealing surfaces, the thickness of the metal plate 1 is 10mm to 20mm, a sealing hole 2 is formed in the middle of the metal plate 1, and nail passing holes 3 for mounting fastening bolts are formed around the sealing hole 2; the glue lines 4 and the nail hole passing glue lines 5 are made of fluorine sulfide, the thickness of the glue lines is 1.5mm, the width of the glue lines is 3mm, a plurality of closed glue lines 4 are arranged on the two sealing surfaces of the metal plate 1 in a mode of surrounding the sealing holes 2, and a plurality of closed nail hole passing glue lines 5 are arranged on the two sealing surfaces of the metal plate 1 in a mode of surrounding the nail hole 3; the sealing surface of the metal plate 1 is also cast with a rib 6 which is just wrapped inside the glue line 4 and the glue line 5 passing through the nail hole.
