It is provided with conducting strip and the lead-in wire being connected with described conducting strip in the storage tank stated, described ring seat sets
Being equipped with the air inlet with its inner space and venthole, described flexible member is arranged on upper bolster and lower mold
The electric connection between conducting strip and the cathode sheets on described upper bolster, described ring seat external diameter it is used between Zuo
Matching with described storage tank external diameter, described diaphragm diameter is more than the internal diameter of described ring seat, institute during installation
State the edge of barrier film between ring seat and storage tank, described upper bolster, die shoe and ring seat are
Insulant.
Further, also including conduction mesh sheet, during test, described conduction mesh sheet is connected with cathode sheets.Profit
Enable to oxygen and cathode sheets uniform contact by the network structure of conduction mesh sheet, and blade mesh sheet can
Cathode sheets is pushed down, places the movement of its position.
Further, for making storage tank can fully fit when installing with ring seat, fully seal, keep away
Exempt from oxygen to leak, in described storage tank, be provided with sealing ring.
As preferably, described ring seat is additionally provided with two circulation ventilatings connected with its inner chamber body
Hole, is connected by trachea between two described circulation ventilating holes.Oxygen is in air inlet enters into ring seat
Can be discharged by venthole again after being circulated by circulation ventilating hole behind chamber, it is possible to be effectively improved oxygen
Utilization rate.
As preferably, described flexible member includes two springs, and one of them spring housing is located at another
In individual spring.Utilize two springs can be effectively improved conducting strip and the moon on conductive effect, and upper bolster
The stability connected between pole piece.
Further, for ease of the connection between described upper bolster and die shoe, described upper bolster and
Being provided with some corresponding through holes on die shoe, bolt is through leading on described upper bolster and die shoe
Both are fixed by hole.
Beneficial effect: in the application, testing mould main body all uses insulant, it is possible to be prevented effectively from
The short circuit phenomenon caused due to mould itself in experimentation；Secondly diaphragm diameter is more than the interior of ring seat
Footpath so that during installation, the edge of barrier film can be between ring seat and containing cavity, in this case
No matter how the lithium sheet under barrier film moves, also will not be with the negative electrode on barrier film under the effect that barrier film intercepts
Sheet contacts, it is to avoid the generation of short circuit phenomenon.
