Abstract
The utility model discloses a kind of sealing structure in the inner cap of resistance to piezoelectric battery hole, its drip irrigation device is：Including battery container, inner cap is provided with battery container, cover inside provided with via, the bottom of via is provided with annular brace circle, O shape seal washers are provided with the inside of annular brace circle, the inner ring top of annular brace circle is provided with screw thread, is provided with closure with what annular brace circle matched, screw thread also is provided with the bottom outer ring of closure.The beneficial effects of the utility model are：The utility model battery container of having determined is assembling the problem of mesopore and lead can be freely movable, fairlead differs smaller with diameter wire, larger stress will not be produced in sealing surface when the mechanisms such as vibration occur for battery and sealing surface is damaged, make sealing structure relatively reliable.
Description
Technical field
It the utility model is related to battery, the sealing knot in the particularly a kind of inner cap of resistance to piezoelectric battery hole suitable in battery
Structure.
Background technology
Existing resistance to piezoelectric battery is multilayer inner cover structure, when vibration occurs or tilts the purpose is to battery again, battery
Interior free alkaline electrolyte is effectively obstructed in Battery body, makes the insulating properties of pressure-bearing Medium Oil in battery compartment not
It is destroyed；But to be closely assembled between lead and interior cap bore in assembling process, can not be up and down, therefore need first welding electrode post again
Lid inner cap, due to much bigger than diameter wire of the six square nuts on pole, therefore the interior hole covered need to be big as six square nuts,
To accomplish to seal, typically it is then coated with epoxide-resin glue with absorbent cotton sealing and carries out solidification sealing, this assembly method step is numerous
Trivial, efficiency is low, and airtight quality can not also detect；And the mode of tight fit is also due to the mechanism such as vibration causes to seal
The destruction in face, the reliability of insulation substantially reduce.
The content of the invention
The purpose of this utility model is to design a kind of sealing knot in the inner cap of resistance to piezoelectric battery hole rational in infrastructure, using effect is good
Structure.
The technical solution of the utility model is that a kind of sealing structure in the inner cap of resistance to piezoelectric battery hole, it includes battery container, its
It is characterised by：Inner cap is provided with battery container, is covered inside provided with via, the bottom of via is provided with annular brace circle, in ring
O shape seal washers are provided with the inside of shape bracing ring, the inner ring top of annular brace circle is provided with screw thread, is set with what annular brace circle matched
There is closure, screw thread also is provided with the bottom outer ring of closure.
The beneficial effects of the utility model are：The utility model determined battery container assembling mesopore can freely be lived with lead
The problem of dynamic, fairlead differs smaller with diameter wire, will not be produced in sealing surface when the mechanisms such as vibration occur for battery
Larger stress and sealing surface is damaged, make sealing structure relatively reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment is described in detail with reference to the figures above, a kind of sealing structure in the inner cap of resistance to piezoelectric battery hole, it includes battery case
Body 1, inner cap 2 is provided with battery container, covers be provided with annular brace circle 5, annular branch provided with via 6, the bottom of via inside
Support ring is structure as a whole with inner cap, O shapes seal washer 4 is provided with the inside of annular brace circle, the inner ring top of annular brace circle is set
There is screw thread, be provided with closure 3 with what annular brace circle matched, screw thread, closure and ring also are provided with the bottom outer ring of closure
Shape bracing ring is coordinated by screw thread to be tightened.
Pole plate group is first put into battery case by the utility model in assembling, then penetrates inner cap, O shapes seal washer suit
In circumferential support circle, closure is finally screwed on, is tightened by screw thread and pushes down O-shaped packing ring, degree can be tightened according to regulation and drawn to control
The degree of cooperation of line and packing ring.It can so accomplish that sealing and can accomplishes flexible combination, while can be by pole plate group in welding electrode post
Extract convenient welding out, reliability and then get a promotion.
Above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.For institute
For the those of ordinary skill in category field, other various forms of changes or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments, and the obvious change or change thus extended out
Within the dynamic protection domain created still in the utility model.
