Specific embodiment

As shown in Figure 1, metallic gasket 11 involved in embodiment has multiple (two to be arranged in the plane Piece) plate (sealed bolster plate) 21,31, two plates 21,31 are connected by being set to the interconnecting piece 41 of mutual counterpart 22,32 It connects.

One plate 21 is formed as the ring bodies for having predetermined outside diameter and internal diameter, the outer ring as the gasket 11.

Another plate 31 is set to be configurable on the size of the internal side diameter of a plate 21, be formed as having predetermined outside diameter with And the ring bodies of internal diameter, the inner ring as the gasket 11.

Metallic gasket 11 is formed as the plate being composed of a plate (outer ring) 21 and another plate (inner ring) 31 Cricoid gasket.Relative to the internal diameter of a plate (outer ring) 21, the outer diameter of another plate (inner ring) 31 is arranged For its same size below, two plates 21,31 do not have the part to coincide with one another (in addition to institute below in a thickness direction as a result, The interconnecting piece 41 stated).Two plates 21,31 can configure in the same plane as a result,.

One plate (outer ring) 21 is the monolayer constructions of metal plate (steel plate).

Another plate (inner ring) 31 by the thickness direction of metal plate (substrate) one or two surface whole faces cover There is the sealing material of certain thickness elastomer to be formed, forms the layer structure of metal plate and elastomer as a result,.As gold Belong to plate, stainless steel, cold-rolled steel sheet, galvanized steel plain sheet or aluminium alloy plate etc. can be used.As elastomer, can be used includes butyronitrile The synthetic rubber plate of at least one of rubber, styrene butadiene ribber, fluorubber, acrylic rubber or silicon rubber (includes Blown rubber) etc..Adhesive layer is set between metal plate and elastomer sometimes, is set between metal plate and adhesive layer sometimes Set base treatment oxidant layer.

Be set to a plate (outer ring) 21 and the counterpart 22,32 of another plate (inner ring) 31 interconnecting piece 41 have under State structure.

First embodiment

That is, as shown in Fig. 2 amplification, interconnecting piece 41 is by being set to the counterpart (Inner peripheral portions) 22 of plate (outer ring) 21 Notch 23 and be set to another plate (inner ring) 31 counterpart (outer peripheral edge portion) 32 and be embedded in notch 23 and engage Protrusion 33 is composed.

Notch 23 continuously has cutout portion 24 and notch extension 25, which is set as one 22 upper opening of counterpart (Inner peripheral portions) of a plate (outer ring) 21 and along (radial from counterpart (Inner peripheral portions) 22 to right angle orientation Outside, right side in figure) direction of recess is extended, and the end in the notch extension 25 and the cutout portion 24 is continuous and edge The direction (top in figure) for being parallel to counterpart (Inner peripheral portions) 22 is extended.

Protrusion 33 continuously has protrusion base portion 34 and protrusion extension 35, which is set as from another The counterpart (outer peripheral edge portion) 32 of plate (inner ring) 31 is prominent and along from counterpart (outer peripheral edge portion) 32, to right angle orientation, (diameter is outside Side, right in figure) direction outstanding is extended, and the protrusion extension 35 is with the end of the protrusion base portion 34 continuously and along parallel It is extended in the direction (top in figure) of counterpart (outer peripheral edge portion) 32.

Therefore, when engaging above-mentioned notch 23 with protrusion 33, as shown in Fig. 2 (A), notch extension 25 and protrusion Protrusion extension 35 is passed through notch extension 25 from the back side of a plate (outer ring) 21 and passed through by the aligned in position of extension 35 It is logical to be inserted into surface side, then, as shown in Fig. 2 (B), a plate (outer ring) 21 is made to be parallel to phase with another 31 edge of plate (inner ring) Direction displacement to portion 22,32, so that protrusion base portion 34 be made to be embedded in notch extension 25.Plane is in the notch of L font as a result, The protrusion 33 that same plane is in L font is embedded in the inner end in portion 23, the protrusion being set on another plate (inner ring) 31 is prolonged Long portion 35 engages with the tongue-shaped holding section 26 for the counterpart 22 for being set to a plate (outer ring) 21, and thereby, it is possible to by two plates 21,31 connection.Interconnecting piece 41 is set at multiple positions it is preferred that changing direction, in this embodiment, as shown in Figure 1, whole be in Ring-type, therefore, circumferentially there are three positions for setting.

According to the connecting structure with above structure, is engaged by notch 23 with protrusion 33 and connect two plates 21,31 It connects, there is no need to use rivet that can connect two plates 21,31, it is therefore not necessary to which riveter follows closely equipment, Connection Step is not numerous It is trivial, component count, component costs can be reduced without using rivet.As a result, compared with the interconnecting piece for using rivet, it can be realized into This reduction and connection process simplify.

In addition, another plate (inner ring) 31 is formed as being covered with elastomer on the surface of metal plate, therefore, it is being set to one The protrusion base portion 34 of the tongue-shaped holding section 26 of a plate (outer ring) 21 and the protrusion 33 for being set to another plate (inner ring) 31 The part being overlapped in the plane, elastomer are compressed by through-thickness, and the metal plate for constituting tongue-shaped holding section 26 passes through it Edge is embedded in elastomer.As a result, compared with the case where metal plate is in contact with each other, protrusion 33 and notch can be significantly set 23 anti-dropout power.

In addition, in the present invention, being not particularly limited the flat shape of notch 23 and protrusion 33.Notch 23 And the flat shape of protrusion 33 is for example also possible to following shape.

Second embodiment

In the embodiment shown in fig. 3, protrusion base portion 34 is set as from 32 edge of counterpart of another plate (inner ring) 31 It is oblique prominent (from protrusion base portion 34 towards oblique with the contrary side outstanding of protrusion extension 35).According to the shape, Interval C from the root of protrusion base portion 34 to cutout portion 24 is set to larger compared with Fig. 2, therefore, can further make to dash forward Portion 33 is played to be difficult to be detached from notch 23.

Third and the 4th embodiment

In Fig. 4 or embodiment shown in fig. 5, the width dimensions of protrusion base portion 34 are set as from protrusion base portion 34 Front end is gradually expanded to root.According to the shape, tongue-shaped holding section 26 and the coincidence part of protrusion base portion 34 in the plane The area divided is arranged larger compared with Fig. 2, therefore increasing friction force can further be such that protrusion 33 is difficult to and notch 23 It is detached from.

5th embodiment

In the embodiment shown in fig. 6, notch extension 25 is from the end in cutout portion 24 to oblique (close to opposite The direction in portion 22 it is oblique) be extended, the width dimensions of holding section 26 are set as the root from tongue-shaped holding section 26 as a result, Portion's forward end is gradually expanded.According to the shape, for the face of holding section 26 and the intersection of protrusion base portion 34 in the plane Product, it is bigger to be abutted against front end area since the root of holding section 26, and frictional force increases, and therefore, can further make protrusion Portion 33 is difficult to be detached from notch 23.

In addition, in the above-described embodiment, a plate 21 and another plate 31 are disposed as ring bodies, by gasket 11 entirety are also configured as ring bodies, but the utility model is without being limited thereto.For example, the outline shape of a plate 21 in outside can also be with It is this rectangle of Fig. 7.

In addition, the content common as each embodiment, consider dimensional tolerance, preferably by notch 23 and protrusion 33 it Between be arranged 0.5~1.0mm degree size gap, in this way, by being arranged in the plane between notch 23 and protrusion 33 Gap can further effectively prevent plate 21,31 to coincide with one another.
