Abstract
The utility model discloses a polar column sealing device, which comprises a polar column and a rubber ring covered at the upper end of the polar column. A circle of groove is arranged outside the upper portion of the polar column, and a circle of protruding edge is arranged on an inner wall of the rubber ring corresponding to the groove. The groove outside the polar column and the protruding edge on the inner wall of the rubber ring are matched. The polar column sealing device is simple in structure and can effectively avoid a phenomenon of acid leakage.
Description
Technical field
The utility model relates to a kind of tubular type lead acid accumulator, particularly a kind of apparatus for sealing pole post.
Background technology
Storage battery be 1859 by Pulan special (Plante) invention, the history in existing more than 100 year so far.Lead acid accumulator has overwhelming superiority in chemical power source after invention always.This is because it is cheap, raw material are easy to obtain, and sufficient reliability is arranged in the use, is applicable to heavy-current discharge and advantage such as ambient temperature range widely.
The trailed model polar post of lead acid batteries is the extension of battery cell both positive and negative polarity, is undertaking the connection task between monomer, realizes interconnecting through intercell connector and pole between each monomer, forms batteries.Realize sealing through the cushion rubber that is pressed between pole and monomer lid, prevent that acid solution in the monomer is along the pole seepage or climb out of tie point is caused corrosion.
Existing pole and cushion rubber are traditional structure; Fit system is enclosed within on the pole for the cushion rubber that internal diameter is less through pressure apparatus by force; Through the cushion rubber madial wall be stretched the distortion realize the sealing; This mode receives the influence of pole and a series of destabilizing factors such as cushion rubber dimensional discrepancy, surface roughness and assembly manipulation deviation easily and causes cooperating and can not accomplish to seal fully, and then pole occurs and leak acid, climb sour phenomenon, and tie point and associated components are caused corrosion; Have influence on the normal use of battery, reveal to clear up after the acid and environment produced and pollute.
The utility model content
Goal of the invention:, the utility model discloses and a kind ofly can prevent effectively to climb that acid is revealed, sour apparatus for sealing pole post to the deficiency of prior art.
Technical scheme: the utility model discloses a kind of apparatus for sealing pole post, comprise pole, cover on the cushion rubber of pole upper end outward; Said pole upper outside is provided with a circle groove, and the inwall of the corresponding groove of cushion rubber is provided with a circle fin.
The groove in the said pole outside and the fin of cushion rubber inwall match.
Its operation principle is to increase by a circle groove at the pole body; Cushion rubber inwall and groove corresponding position design one circle fin; With after pole cooperates fully, fin also can cooperate with groove at cushion rubber, and the back cushion rubber fin that is squeezed is full of groove just; Cushion rubber and pole are combined as a whole with pole on certain interval like this, just can effectively avoid Lou acid and climb sour phenomenon.
Beneficial effect: the disclosed a kind of apparatus for sealing pole post of the utility model, simple in structure, can effectively avoid Lou acid and climb sour phenomenon.
Description of drawings
Accompanying drawing 1 is the rough schematic of apparatus for sealing pole post.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to explain.
The utility model discloses a kind of apparatus for sealing pole post, comprise pole 1, cover on the cushion rubber 2 of pole upper end outward; Said pole 1 upper outside is provided with a circle groove, and the inwall of cushion rubber 2 corresponding grooves is provided with a circle fin.
The groove in said pole 1 outside and the fin of cushion rubber 2 inwalls match.
Its operation principle is to increase by a circle groove at the pole body; Cushion rubber inwall and groove corresponding position design one circle fin; With after pole cooperates fully, fin also can cooperate with groove at cushion rubber, and the back cushion rubber fin that is squeezed is full of groove just; Cushion rubber and pole are combined as a whole with pole on certain interval like this, just can effectively avoid Lou acid and climb sour phenomenon.
The utility model provides a kind of thinking and method of apparatus for sealing pole post; The method and the approach of concrete this technical scheme of realization are a lot; The above only is the preferred implementation of the utility model, should be pointed out that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model, and all available prior art of each part not clear and definite in the present embodiment realizes.
