L " shape pin is the mechanical type arm with higher-strength, the vent port at accumulator tegillum two ends firmly can be blocked, and avoids in pressure process because of the not enough generation of shutoff power gas leak phenomenon.
As further improving and optimization to of the present utility model, also be provided with aerating device on the described support plate by electric liquid display panel through hole inflation, described aerating device comprises pneumatic head.Change into electric liquid display panel through hole inflation by the mode that battery tegillum two ends vent port is inflated existing, safe and reliable.
Described device frame comprises upper table surface and the following table that is parallel to each other, and upper table surface is connected to a fixed head mutually by guide pillar, and this guide pillar is by a cylinder control unit frame lifting.Utilize the easy on and off lifting of cylinder control guide pillar implement device frame, compare by manually accumulator being carried out lifting more laborsaving.
The two ends of described upper table surface and following table link to each other by riser, and the side of described riser has vertical chute, and described support plate is connected to fixed head mutually by the lifting guide pillar, and the lifting guide pillar is by the lifting of cylinder control support plate.Utilize the moving up and down of pressure control support plate of cylinder, can satisfy the detection position requirement of different size accumulator, and keep pneumatic head can fit tightly on electric liquid display panel through hole, guarantee that gas replenishment process has good air-tightness.
Described support plate is provided with plural number to pin and aerating device, has the regulating tank of plurality of parallel on the described support plate, and described pin and pneumatic head connect by web member and regulating tank.Can carry out impermeability to a plurality of accumulator tegillums simultaneously detects, being convenient to pin carries out parallel and fine setting vertical direction with pneumatic head, the vent port and the electric liquid display panel through hole at itself and different model accumulator tegillum two ends are matched, improved the scope of application and the detection efficiency of this device.
The outer end of described pneumatic head and plug has sealing gasket, and described sealing gasket is a rubber, and described rubber has the shutoff shrinkage pool and one side is bonded on the sealing surface of plug and pneumatic head outer end.Rubber is generally industrial vulcanized rubber, and the shrinkage pool that has on rubber makes its vent port that can coat the accumulator two ends and electric liquid display panel through hole, and sealing effectiveness is better.
The beneficial effects of the utility model are embodied in: will have now to reveal and put aerial detection method and change pick-up unit and the method that is immersed in the water into, the inflation of pressurizeing again after being placed on accumulator in the water, the bubble that less gas leak phenomenon can produce from water is found out, and bigger gas leak phenomenon can detect by tensimeter simultaneously.The sealing that adopts aforesaid way to detect the accumulator tegillum is compared single more simple and clear by the variation of tensimeter detection internal storage battery pressure.The utility model is inflated by electric liquid display panel through hole on the other hand, has changed the inflation inlet of existing product, and gas replenishment process safety can not cause secondary to damage and causes scrapping the accumulator tegillum.
