Description

The battery condition display

Technical field

The utility model relates to a kind of storage battery and makes field, especially a kind of battery condition display that is used to show accumulator electric-quantity.

Background technology

The situation that electric quantity change and electrolyte reduce in use must take place in storage battery, relies on the instrument test cost too high.Chinese patent (patent No. 01263482.4) discloses a kind of electric quantity display device, but there is following defective in it: fixed cover (being the column sleeve in the utility model) inside is provided with liner, inner lining surface is provided with circular protrusion, its complex structure, not only manufacturing cost improves, and all tiny property at parts of edges and corners are all damaged easily; The power thrusts of screwed bayonet (being the breach in the utility model) is unreasonable, and the storage battery service condition is abominable, and corrosion easily when dismounting, often causes the column sleeve marginal laceration, does not tear open not get off; Corner stress is concentrated, and is easy to generate crackle and scraps; Compress sealing ring by boss, skew is arranged during installation slightly, just easy electrolyte leakage.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, and a kind of simple and reasonable, battery condition display that result of use is good is provided.

The utility model solves the technical scheme that its technical problem adopts: this battery condition display, comprise transparent stand column, column sleeve, the upper end of transparent stand column is stuck in the column sleeve, and column top is provided with the circular fin of at least one circle to outer lug, and column is by this circular fin and column sleeve interference fit.By circular fin, the tight clamping of column sleeve and column had both guaranteed intensity, had guaranteed that also electrolyte can not leak from faying face.This structure is compared with background technology, has saved the shaft shoulder structure of the inner lining structure and the column of column sleeve, and is simple and reasonable, effective, long service life; The mfg. moulding die of column sleeve is succinct in addition, and the column sleeve fastness is strengthened.

The utility model can be further perfect by following manner:

The column sleeve top periphery is provided with two loading and unloading breach, overlooks to be fan-shaped; The bottom opening of breach is big, and upper opening is little, and side-looking is swallow-tail form.Breach corner arc transition.The breach of column sleeve is fan-shaped, when turning column sleeve, generation be rotated in force of tangential direction; And breach is dovetail shaped in the side, in case specific purpose tool inserts, is difficult for slippage; The rotation angle position that all stress are concentrated all is provided with arc transition, has not only strengthened fastness, also makes in the manufacture process to be convenient in demoulding.

The T shape end face of column sleeve is arranged with the ring-type chase that is used to place rubber seal, and its corner arc transition.Boss under the cancellation column sleeve T shape end face, the corner arc transition, one locatees rubber seal automatically, and two eliminate stress, and have also increased the area that compresses to sealing ring, make leakproof more reliable.

The effect that the utility model is useful is: the utility model mainly is to consider from optimizing performance, in limited space, strengthens the intensity and the function of thin-walled parts, and makes manufacturing convenient, can obviously improve the quality of products.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to accompanying drawing: this battery condition display comprises transparent stand column 1, column sleeve 2, rubber seal 3, red color pearl 4, green tint pearl 5 and positioning sleeve 6.The upper end of transparent stand column 1 is stuck in 2 li of column sleeves, and column 1 top is provided with the circular fin 1-1 of at least one circle to outer lug, and column 1 is by this circular fin 1-1 and column sleeve 2 interference fit.Column sleeve 2 top periphery are provided with two loading and unloading breach 2-1, overlook to be fan-shaped; The bottom opening of breach 2-1 is big, and upper opening is little, and side-looking is swallow-tail form.Breach 2-1 corner arc transition.The T shape end face of column sleeve 2 is arranged with ring-type chase 2-2 and its corner arc transition that is used to place rubber seal 3.

Transparent stand column 1 upper surface is an observation window, at storage battery electricity arranged, need charging, need can show three kinds of different combinations of patterns under three kinds of states of fluid infusion, thereby the prompting user grasps situation easily, in time takes measures.The circular fin 1-1 of two road arc convex is arranged at column top, is used for fixing column sleeve 2.Held different red color pearl 4, the green tint pearls 5 of two granule densities in the cavity of transparent stand column 1 bottom, the diameter of cavity and length can allow color pearl can freely fluctuate and not change order.Column 1 bottom is provided with light cone, is used for the location status of color pearl is reflexed on the observation window, demonstrates different combinations of patterns.Column 1 bottom external diameter is thin slightly, is used for fixing positioning sleeve 6, and the effect of fixed cover 6 is that following color pearl is limited in the reflex scope of light cone.On column 1 and the fixed cover 6 plurality of holes is arranged all, be convenient to electrolyte and flow freely.

Column 1 and fixed cover 6 are all made with the PMMA acryl, are transparence, and red color pearl 4, green tint pearl 5 have been adopted the red and green of traffic lights.When two color pearls all float over top, all sink to a bottom or an agglomerate tabling and another grain when sinking to the bottom in the above, under the light reflex of column 1 light cone, can see three kinds of different combinations of patterns at the watch window of column 1 end face, the prompting user takes corresponding measure (continuing to use, charge, mend electrolyte).

The proportion of red color pearl 4 is less than 1, float over forever electrolyte above; The proportion of green tint pearl 5 is a little less than 1.28G/CM ³, behind lead acid battery charge, density of electrolyte increases, and green tint pearl 5 floats, and is close to red color pearl 4, presents the pattern of green ring around red point at watch window, expression electric weight abundance;

Be accompanied by the use discharge of storage battery, density of electrolyte reduces, and when being lower than a certain critical value, green tint pearl 5 can sink to the electrolyte bottom and go, and red color pearl 4 separates with green tint pearl 5, disappears at the green ring of watch window, presents red point, and expression needs to charge;

Use with the passing of time, electrolyte is owing to reasons such as volatilizations, and electrolysis liquid surface reduces, red color pearl 4 descends thereupon, and hot color pearl 4 drops to and is close to green tint pearl 5, and two color pearls are when all resting positioning sleeve 6 lower ends, watch window presents the pattern of red ring around red point, and expression needs to have replenished electrolyte.
