Specific embodiment
Presently in connection with drawings and examples, the present invention is described in further detail, these attached drawings are simplified signal
Figure, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
As depicted in figs. 1 and 2, a kind of inner lining body of silicon rubber shrinkage part, comprising: the elastomer of sheet, the two of elastomer
Face is respectively the inner surface and the outer surface, and elastomer a side end face is equipped with recessed arc groove, close to another side of elastomer and
The arc that protrusion is provided on inner surface is convex stupefied, and three recessed folding slots are provided on inner surface, and folding slot is V-shape knot
Structure.
By the convex stupefied mating structure with arc groove of setting arc, guarantee that elastomer can form tubular or column by bending
