The pedestal that the surrounding of the elastic packing block is corresponding is tightly connected；
The pedestal is equipped with and applies stressed inflating port to the elastic packing block, which is connected by gas ducting
Connect air source.
Further, fastening plates before being equipped with one between the product to be measured that each elastic packing block is abutted with it, institute
The fastening plates position opposite with the elastic packing block is equipped with trepanning before stating；The elastic packing block is applied by the inflating port
Pressure, and partially pass through after the trepanning squeezes out and be connected in the opening or outer rim of product to be measured.
Specifically, the preceding fastening plates are fixed by screws on its corresponding pedestal.
Specifically, the elastic packing block is set as a plate-like elastic sealing block, and the plate-like elastic sealing block clamps solid
It is scheduled between the preceding fastening plates and the pedestal.
Further, the elastic packing block is made of rubber or silica gel.
Further, the gas ducting is equipped with pressure control device.
The utility model contacts hermetic unit using elastic packing block as with test product, by being applied to elastic packing block
Plus-pressure is inflated by inflating port on pedestal so that elastic packing block is expanded to product to be measured, is enabled elastic packing block and is tested
Product is fitted closely with outer surface, to the person's of reaching sealing effect.
Compared with prior art, the utility model has the advantages of simple structure, at low cost, elastic packing block can very well with product to be measured
It fits closely, it is good to the sealing effect of the opening of product to be measured.
