Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Fig. 1 ~ 4, the double positioning epitheliums of the automobile, including epithelium ontology 1, the lower surface of the epithelium ontology 1
Center is provided with circular pit 11, and there are two downwardly projecting main convex mouth 12, two masters are convex for the surface setting of the epithelium ontology 1
Mouth 12 is symmetricly set on the outside of pit 11, and the inner cavity of the main convex mouth 12 is provided with secondary convex mouth 122 protruding upward, the pair
The inner cavity of convex mouth 122 is connected with the inner cavity of main convex mouth 12；There are two boss protruding upward for the surface setting of the epithelium ontology 1
13, two boss 13 are symmetricly set on the outside of pit 11, and the edge of the epithelium ontology 1 is provided with the flange being turned over downwards
16；The first anti-skidding muscle group 14 is provided between the boss 13 and flange 16, the first anti-skidding muscle group 14 is arranged on by multiple
First anti-skidding muscle 141 of 1 upper surface of epithelium ontology forms；The second anti-skidding muscle group is provided between the main convex mouth 12 and flange 16
15, the second anti-skidding muscle group 15 is made of multiple the second anti-skidding muscle 151 for being arranged on 1 upper surface of epithelium ontology；The epithelium
The surface of ontology 1 is additionally provided with multiple radial direction folds 17, and the radial direction fold 17 is symmetricly set on the outside of pit 11, the diameter
To fold 17 between pit 11 and flange 16.
Herein, described is for Fig. 2 above and below.The double positioning epitheliums of the automobile are for vacuum automobile
Booster, described two main convex mouthes 12 are fixed on vacuum booster inner tray, meanwhile, there are two axis pins to pass through secondary convex mouth 122,
