Abstract
The utility model discloses a novel maintenance-free lead-acid storage battery cover and a storage battery using the battery cover. The maintenance-free lead-acid storage battery cover comprises a cover plate, wherein two through holes are symmetrically formed in the cover plate; rivets are riveted in the through holes; metal elastic pieces are fixed on inner walls of the through holes through the rivets; one part of the metal elastic pieces is positioned above the cover plate, and the other part of the metal elastic pieces is positioned below the cover plate; the part of metal elastic pieces positioned below the cover plate is connected with a battery pole; the part of metal elastic pieces positioned above the cover plate is connected with a binding post; two explosion-proof valves are symmetrically arranged on the cover plate; the two explosion-proof valves are close to the edge of the cover plate. According to the storage battery and storage battery cover, displacement of the metal elastic pieces can be limited through the rivets, an effect of sealing the through holes can be achieved, and the explosion-proof valves are symmetrically arranged at two ends of the cover plate. Compared with a structure that only one explosion-proof valve is arranged on the cover plate in the prior art, the storage battery cover has the advantages that the pressure can be timely released when the pressure in the storage battery is extremely high, the two explosion-proof valves are relatively far away from each other and are arranged at two ends of the cover plate, thereby achieving a better pressure relief effect and further ensuring the safety performance of the battery.
Description
Technical field
The utility model relates to storage battery production field, relates in particular to a kind of novel maintenance-free lead-acid battery lid battery cap and uses the storage battery of this battery cap.
Background technology
Because lead acid accumulator is cheap, raw material are easy to get, dependable performance, easily reclaim and be suitable for the features such as heavy-current discharge, become output maximum, purposes storage battery the most widely in the world.Conventional lead acid accumulator mainly contains two kinds, a kind of is the lead acid accumulator (wet type) that adds electrolyte, another kind is the storage battery (barren liquor type) of non-maintaining type, maintenance free cell (barren liquor type) is due to the advantage in self structure, the consumption of electrolyte is very little, substantially the concentration that does not need to supplement distilled water and regulate electrolyte within useful life, hermetic, have and safeguard simply, shatter-proof, high temperature resistant, volume is little, the feature that self discharge is little, but, in use there is voltage in barren liquor type maintenance free cell, capacity, uneven quality problems of life-span, and its manufacturing process is more complicated, cost is higher.Wet type lead acid accumulator, can overcome the problem of barren liquor type maintenance free cell, but it need to safeguard storage battery frequently, troublesome maintenance, wastes time and energy.Therefore, utility model patent 201220234372.7 discloses a kind of maintenance-free lead accumulator, comprise have hollow reservoir housing, be located at cap on housing, be located at electrolyte in housing with pole plate group and be located at the electrode column being connected with pole plate group on cap, described pole plate group comprises positive plate, negative plate and is located at the dividing plate between each positive and negative pole plate, in described housing, be positioned at electrolyte top and be provided with paraffin every liquid layer, described cap is provided with installing hole, removable fluid injection plug or the explosion-proof hydrogen eliminator of being provided with on described installing hole.
But, lead acid accumulator of the prior art also exists another kind of defect, that is exactly in use, if the pressure in storage battery is excessive, likely produce blast, although and be provided with explosion-proof hydrogen eliminator in said structure, but still exist the situation of pressure release in time, meanwhile, the setting of fluid injection plug also exists the danger because of loosening leakage often; And in prior art for fear of cause the excessive phenomenon of electrolyte leakage because accumulator housing is not airtight, on cap, add dust cap, and arranging of dust cap increased battery production technology step on the one hand, increase cost, dust-proof effect is bad on the other hand, easily damage, further increased again maintenance cost.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, provides one can effectively avoid storage battery to blast because internal pressure is excessive, again can be effectively dustproof, avoid the battery cap that electrolyte leaks and the storage battery that uses this battery cap.
For addressing the above problem, a kind of novel maintenance-free lead-acid battery lid of the present utility model and use the storage battery of this battery cover, comprises cover plate, is symmetrically arranged with two through holes on cover plate, in through hole, riveting has rivet, on the inwall of through hole, is fixed with metal clips by rivet; Described metal clips part is positioned at cover plate top, and part is positioned at cover plate below; The described part metals shell fragment that is positioned at cover plate below connects battery electrode column, and the part metals shell fragment that is positioned at cover plate top connects binding post; On described cover plate, be also symmetrically arranged with two explosion-proof valves, described two explosion-proof valves are positioned at the position near side edge thereof.
Described explosion-proof valve is circular, on its surface, is provided with line of weakness.
Described storage battery have hollow reservoir housing, be located at the battery electrode column that the electrolyte in housing is connected with pole plate group and with pole plate group, described pole plate group comprises positive plate, negative plate and is located at the dividing plate between each positive and negative pole plate, also comprises foregoing battery cap.
Adopt a kind of novel maintenance-free lead-acid battery lid of the utility model structure and use the storage battery of this battery cover, can limit by rivet the displacement of metal clips, and can play the effect of through hole sealing, two ends at cover plate are symmetrically arranged with explosion-proof valve, with respect to the structure of only having an explosion-proof valve in prior art cover plate, more can timely pressure release in the time that accumulator internal pressure power increases, and by two explosion-proof valves relatively away from being arranged on cover plate two ends, pressure release better effects if, and then the security performance of guarantee battery.
