Abstract

The utility model discloses an electrode protecting cover of a dry battery. The electrode protecting cover comprises a plastic cover body, wherein the plastic cover body forms a trapezoid shape in which the upper part is small and the lower part is large; the plastic cover body comprises an inner cavity with a downward opening for inserting a copper electrode cap of the dry battery; and furthermore, a flange structure which is in over-tight fit with the outer lateral wall of the lower end of the copper cap is arranged at the inner lateral wall of the lower end of the plastic cover body. By adopting the protecting cover, the plastic cover body is locked on the copper electrode cap to cover the copper cap. Therefore, not only can bad contact of the dry battery caused by oxidization of the anode copper cap be effectively prevented, but also the phenomenon of short circuits at two poles of the dry battery can be avoided; the safety is greatly improved; and the protecting cover is simple in structure and convenient to use.

Description

A kind of dry cell electrode protection lid

Technical field

The utility model relates to a kind of over cap, relates in particular to a kind of dry cell electrode protection lid.

Background technology

Dry cell is comprised of parts such as the manganese powder that contains electrolyte, zinc cylinder, copper cap and carbon-points, wherein, be provided with lid above the zinc cylinder, the below is provided with at the bottom of the negative pole iron, be inserted with carbon-point in the manganese powder, form positive pole with the copper cap on the carbon-point, be provided with slurry paper separator between manganese powder and the zinc cylinder, be placed with basin type paper washer in zinc cylinder bottom, below lid paper washer and pitch are housed, play the leakproof effect as sealing layer, it is air chamber that one section space is arranged between manganese powder and the sealing layer, be mist and the liquid that storage manganese powder and zinc cylinder produce in the exoelectrical reaction process, prevent from expanding.The Plastic shell dry battery of producing has at present remedied the shortcoming of conventional dry cell batteries, has brought a lot of convenient and selections for consumer's use, and still, in the use procedure of reality, the electrode protection of dry cell still is problem demanding prompt solution.

On the one hand, after the packing of dry cell was sealed off, dry cell can not be installed in the house articles for use that are of little use for a long time, such as flashlight, calculator, remote controller etc., otherwise can generating electrodes oxidation, even the dry cell leakage occurs and corrode electrical equipment, the serious problems that therefore dry cell is scrapped.Therefore; people can only take out dry cell; be kept in addition in the storage devices such as pen container, drawer; yet; this preserving type can bring extremely serious adverse consequences to dry cell: dry cell electrode (utmost point of making a comment or criticism) copper cap does not obtain any protection; easily because air humidity is overweight or former thereby cause oxidation with the hand contact of water stain, sweat stain etc., even get rusty, greatly affect its electrical property.

On the other hand; in order to prevent the two poles of the earth short circuit of dry cell; people paste protector at the two poles of the earth of being everlasting; but protector can be because break away from the two poles of the earth with mixed the putting of other article; also be easy to because the absorption dust comes off from the two poles of the earth, the dry cell of the protector that come off is easy to occur the phenomenon of the two poles of the earth short circuit by common conductive articles such as coin, keys; even cause the dry cell blast, thereby cause serious security incident.

The utility model content

For the deficiencies in the prior art; the purpose of this utility model is intended to provide a kind of dry cell electrode protection simple in structure, easy to use lid; it can not only effectively prevent the loose contact that dry cell causes because of the oxidation of anodal copper cap; can also avoid occurring the phenomenon of dry cell the two poles of the earth short circuit, greatly improve fail safe.

The utility model adopts following technical scheme for achieving the above object:

A kind of dry cell electrode protection lid; comprise a plastic cement lid; this plastic cement lid is presented little lower large trapezoidal shape; it has the inner chamber that inserts for dry cell electrode copper cap under shed; and the lower end madial wall of this plastic cement lid is provided with for carrying out friction tight flanged structure with copper cap lower end lateral wall.

Wherein, the curved shape of described flanged structure.

Wherein, offer on the two side of described plastic cement lid symmetrical, be convenient to through hole that plastic cover is taken off from the copper cap, under the use state, through hole is positioned at the top of copper cap.

A kind of dry cell electrode protection lid that the utility model is set forth; its beneficial effect is: adopt this over cap; the plastic cement lid is buckled on the electrode copper cap; the copper sunshade is covered; can not only prevent effectively that dry cell from because of the loose contact that the oxidation of anodal copper cap causes, can also avoid occurring the phenomenon of dry cell the two poles of the earth short circuit, greatly improve fail safe; and over cap is simple in structure, uses also very convenient.

Embodiment

Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.

Please refer to Fig. 1 and shown in Figure 2; it has demonstrated the concrete structure of the utility model preferred embodiment; a kind of dry cell electrode protection lid; comprise a plastic cement lid 10; this plastic cement lid 10 is up-small and down-big trapezoidal shape; it has the inner chamber 11 that inserts for dry cell electrode copper cap 20 under shed; and; the lower end madial wall of this plastic cement lid 10 is provided with for carrying out friction tight flanged structure 12 with copper cap 20 lower end lateral walls; and flanged structure 12 curved shapes, best with the tension fiting effect of copper cap 20.

Wherein, offer symmetrical through hole 13 on the two side of described plastic cement lid 10, under the use state, through hole 13 is positioned at the top of copper cap 20, like this, utilizes nail easily plastic cement lid 10 to be taken off from copper cap 20.

During use; plastic cement lid 10 is buckled on the anodal copper cap 20 of dry cell; thereby copper cap 20 is covered in; can not only effectively prevent the loose contact that dry cell causes because of anodal copper cap 20 oxidations; can also avoid occurring the phenomenon of dry cell the two poles of the earth short circuit; greatly improved fail safe; because plastic cement lid 10 elasticity are good; utilize flanged structure 12; plastic cement lid 10 can carry out the extraordinary tight fit of crossing with anodal copper cap 20; the phenomenon that plastic cement lid 10 breaks away from from copper cap 20 can not appear in putting of any angle of dry cell, and over cap structure of the present utility model is very simple, uses also very convenient.

The above, it only is the utility model preferred embodiment, be not that technical scope of the present utility model is imposed any restrictions, therefore every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment does.
