Description
Technical field
The utility model relates to Lead-acid Battery Technology fields, and in particular to a kind of lead-acid battery lid.
Background technique
Lead-acid accumulator is to realize that chemical energy is transformed into a kind of device of direct current energy, existing Automobile Lead Acid Batteries
It is commonly used for maintenance-free lead accumulator.Automobile maintenance-free lead accumulator, in actual use, due to battery installation site
Usually in engine bin, environment temperature is higher, causes battery dehydration more, terminates the service life in advance, at this time internal storage battery
The pole plate service life does not terminate, if suitable replenisher is added, can proceed with use.In previous design: battery is manufacturing
When sealing user's use process in cannot add liquid；Or the design of accumulator liquid feeding hole is unreasonable, and battery is caused to use
The problems such as liquid filling hole leakage is easily caused due to vehicle vibration and charging in journey.
Summary of the invention
A kind of good leak tightness is provided the purpose of the utility model is to overcome the above-mentioned insufficient of the prior art, can liquid feeding
Lead-acid battery lid.
The technical solution of the utility model is: the middle cover including step, and boss is arranged at middle cap upper surface top, sets on boss
Fluted, bottom portion of groove is equipped with more than one liquid injection hole；It further include attaching together the upper cover matched by heat-sealable with middle cover, on upper lid
Equipped with liquid filling hole corresponding with fluid injection hole site；Vent plug is interior loaded on liquid filling hole and is threadedly coupled with liquid filling hole；The liquid injection hole
Bottom downwards, extend inwardly to form reflux inclined-plane；The seal washer of annular, liquid filling hole and gasket are cased on the vent plug
The bottom for enclosing contact position is equipped with the wedge angle protrusion of annular.
The liquid injection hole has 6.
The groove is cuboid, and 6 liquid injection holes are linearly evenly distributed in bottom portion of groove along groove length direction.
It is set in the groove there are two location hole, is correspondingly provided with the positioning convex platform being used cooperatively with location hole on upper lid.
The middle cap upper surface both ends are equipped with positive lead circle, negative electrode lead circle.
The utility model has the beneficial effects that: good leak tightness, can liquid feeding, when the excessive feelings of dehydration occurs in lead-acid accumulator
Under condition, liquid feeding supplement can be carried out by opening vent plug, to extend the service life of battery, reduce the frequency of battery replacement
And cost.

Specific embodiment
In Fig. 1, a kind of lead-acid battery lid, the middle cover 1 including step, boss is arranged at 1 upper surface top of middle cover.Further include
The upper cover 2 matched is attached together by heat-sealable with middle cover 1,1 upper surface both ends of middle cover are equipped with positive lead circle 4, negative electrode lead circle 5.In upper cover 2
Equipped with liquid filling hole 8 corresponding with 7 position of liquid injection hole.Vent plug 3 is interior loaded on liquid filling hole 8 and is threadedly coupled with liquid filling hole 8.Vent plug
3 with upper cover 2 by being threadedly engaged, facilitate vent plug 3 to dismantle liquid feeding and installation.The middle cover 1 of the utility model cancels return port, note
Fluid apertures 7 takes on reflux effect.On the one hand it can increase liquid feeding hole area in the useful space, facilitate liquid feeding；On the other hand, liquid injection hole
7 bottom extends downwardly and inwardly to form reflux inclined-plane, facilitates inside cooling liquid reflux to cell body, effectively prevent electric power storage
Pond liquid overflows.
In Fig. 2, boss is arranged at the middle cover 1 of step, 1 upper surface top of middle cover.Boss is equipped with groove 6, and 6 bottom of groove is set
There are 6 liquid injection holes 7.Groove 6 is cuboid, and 6 liquid injection holes 7 are linearly evenly distributed in bottom portion of groove along 6 length direction of groove.
The bottom of liquid injection hole 7 extends downwardly and inwardly to form reflux inclined-plane.1 upper surface both ends of middle cover are equipped with positive lead circle 4, negative electrode lead circle 5.
It sets to heat there are two location hole 11, upper cover 2 and middle cover 1 by plastic cement in groove 6 and seals installation, the positioning convex platform 12 in upper cover 2
It is inserted into and cooperates with the location hole 11 of middle cover 1, prevent upper cover 2 from heating in sealing installation process with middle cover 1 and misplace.
In Fig. 3, upper cover 2 is matched with middle cover 1 by heat-sealable attach together.Upper cover 2 is equipped with liquid feeding corresponding with 7 position of liquid injection hole
Hole 8.Vent plug 3 is interior loaded on liquid filling hole 8 and is threadedly coupled with liquid filling hole 8.It is correspondingly provided in upper cover 2 and is used cooperatively with location hole 11
