Abstract

The utility model relates to a battery cap, which comprises a cap wall and a cap bottom, wherein the shape of the cap wall is adaptive with the shape of a battery; the shape of the cap bottom is adaptive with the shape of the cap wall; the cap bottom is internally provided with a cap bottom bulge; and the cap wall is internally provided with a cap wall bulge. The battery cap has the advantages that the battery cap can well prevent the leakage of the electrolytic solution caused by collision and the short circuit between storage batteries.

Description

Battery cap

Technical field

The utility model belongs to the field of battery transportation, particularly a kind of battery cap.

Background technology

The sealing wet storage battery that we use now; alkalescence or acidic electrolysis bath have been adsorbed in sealing wet storage battery inside in pole plate and dividing plate; has the existence of a spot of free electrolyte; in particularly transport by sea process at a distance; stand vibration and pressure; the test of changes in environmental conditions such as temperature; if there is defective in storage battery on structural design or material selection; electrode is not subjected to good anti-short-circuit protection; just cell jar occurring probably in transportation breaks; cell jar separates cracking with battery cap; storage battery short circuit after the dividing plate displacement; the battery post fracture causes short circuit to cause electrolyte leakage or storage battery blast on fire; alkalescence or acidic electrolysis bath will produce corrosion to goods on every side and transporting equipment, the harm person and transporting equipment safety.A lot of transportation safety accidents that exist defective to cause electrolyte leakage or blast on fire to cause because of accumulator structure design, material selection or manner of packing have appearred this year successively, not only cause bigger economic loss and environmental pollution accident, also directly influenced the image and the reputation of manufacturing enterprise.Therefore, how correctly to estimate the dangerous transportation and packing attribute of sealing wet storage battery and select suitable packaging type, become the problem that storage battery and packing manufacturing enterprise thereof and inspection body pay close attention to and inquire into.

According to the experience of outlet Transport Packages of Dangerous Goods Performance Detection and evaluation, sealing wet storage battery dangerous cargo transporting package attribute evaluation is mainly determined the performance of 2 aspects:

1) in a single day the preventing liquid leakage performance of storage battery because electrolyte leakage occurs in transportation, will bring great harm to means of transportation;

2) the packaging protecting performance of the anti-short circuit of battery terminal, because be short-circuited, storage battery can produce a large amount of heats in the short period of time, when serious even can produce blast and cause fire.

The utility model content

The utility model needs the problem that solves in transit for solving to have now at storage battery, proposes a kind of battery cap, can well prevent to collide the electrolyte leakage of generation and the short circuit problem between the storage battery.

To achieve the above object, the technical solution of the utility model is as follows:

A kind of battery cap comprises;

The cap wall is the shape adaptive with cell shapes;

At the bottom of the cap, for the adaptive shape of described cap wall; Projection at the bottom of inside is provided with cap at the bottom of the described cap is provided with cap wall projection in described cap wall.

It is cylindrical further to be characterized as being shaped as of described cap wall.

Further at the bottom of the described cap of feature be and the adaptive circle of cap wall shape.

Further the described cap wall of feature projection is an annular protrusion.

Further projection is the annular protrusion that internal edge is provided with at the bottom of described cap at the bottom of the described cap of feature.

Advantage of the present utility model is: the battery cap of rubber material is enclosed within on the metal cap head of storage battery, because the annular protrusion at the bottom of the battery cap cap, the metal cap head of battery does not contact with any part of battery cap, and the metal cap head is just in the space that the front end and the battery crown madial wall annular protrusion of battery protection cap surrounded; In the process of transportation, electrolyte leakage that produces in the time of can well preventing to collide and the short circuit problem between the storage battery, and the bump that produces in effective buffer battery falling process prevent the battery cap distortion.

Fig. 1 is an example structure schematic diagram of the present utility model.

Embodiment

Below by specific instantiation and accompanying drawings execution mode of the present utility model, those skilled in the art can understand other advantage of the present utility model and effect easily by the content that this specification disclosed.The utility model also can be implemented or be used by other different instantiation, and the every details in this specification also can be based on different viewpoints and application, carries out various modifications and change under the spirit of the present utility model not deviating from.

As shown in Figure 1, battery cap of the present utility model, a kind of battery cap, comprise at the bottom of cap wall 1 and the cap 2, wherein cap wall 1 is the shape adaptive with the battery outer shape, and storage battery has a lot of shapes, have square or circular, according to the shape of battery, battery cap can be square or circular, and is generally preferably cylindrical.2 is adaptive with cap wall 1 shape at the bottom of the cap, is preferably circle.The cap wall projection 3 that is provided with on cap wall 1 inwall is annular or square and cap wall 1 shape is adaptive, projection 4 at the bottom of 2 internal edges are provided with ring cap at the bottom of the cap.

Battery cap material of the present utility model is a rubber; flexible; and insulation; be enclosed within on the metal cap head of storage battery; because projection 4 at the bottom of the cap at the bottom of the battery cap cap; the metal cap head of battery does not contact with any part of battery cap; the metal cap head is just in the space that the front end and the battery crown madial wall annular protrusion of battery protection cap surrounded; can play the effect of buffering; can not produce big collision in transit; prevented the short circuit problem between electrolyte leakage and the storage battery; the bump that produces in projection 4 effective buffer battery falling process at the bottom of cap wall projection 3 in the battery cap and the cap prevents the battery cap distortion, and cap wall projection 3 also can play the effect of reinforcing the battery cap socket; be not easy to come off, when transportation, just meet country like this Transport Packages of Dangerous Goods Performance Detection and evaluation.

The foregoing description is illustrative principle of the present utility model and effect thereof only, but not is used to limit the utility model.Any those skilled in the art all can be under spirit of the present utility model and category, and the foregoing description is modified and changed.Therefore, rights protection scope of the present utility model should be listed as claims.
