Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-7 are referred to, the utility model provides a kind of technical scheme：A kind of multilayer metal gasket, including pad are fixed
Part 1, cushion 2 is installed outside pad fixture 1, and pad fixture 1 is internally provided with bolt hole 6, and pad is fixed
Fricting strip 7 is installed, fricting strip 7 is distributed in the surface of pad fixture 1 in circular uniform vertical, and fricting strip 7 can be with outside part 1
Increase the frictional force between bolt and metallic gasket, can effectively prevent bolt looseness, the outside of cushion 2 sets elasticity layer
3, cushion 2 includes buffering layer main body 201, cushion transverse wave 202 and the vertical ripple 203 of cushion, and buffers layer main body
201 bottoms are provided with cushion transverse wave 202, and buffering layer main body 201 is internally provided with the vertical ripple 203 of cushion, buffered
