Abstract
The utility model relates to an accumulator lid, which aims to provide a seepage prevention accumulator lid, comprising a plug screw body 1, a seepage prevention net 2, and a harness 3. A cavity is provided in the plug screw body 1, and the harness 3 is provided in the cavity. The seepage prevention net 2 which is arranged horizontally is fixed to the place between the plug screw body 1 and the harness 3. After the electrolyte which is arranged in the accumulator contacts with the seepage prevention net 2, a layer of liquid film which is used to prevent the seepage of the electrolytic is formed owing to the function of surface tension; while gas can be exhausted from the vents which are provided on the plug screw body 1 through the meshes of the seepage prevention net 2. The utility model settles the defect that gas discharge and liquid sealing can not be simultaneously guaranteed easily in the prior art, and the seepage prevention accumulator lid can be adopt in various liquid accumulators.
Description
Technical field
The utility model relates to a kind of battery cap, more particularly, relates to a kind of seepage prevention battery cap.
Background technology
The present battery cap that uses, ubiquity a kind of defective, and that is exactly that electrolyte easily overflows from battery cap, makes the both positive and negative polarity conducting, thereby causes the phenomenon of storage battery self-discharge to take place.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of simple in structure, battery cap of being difficult for discharge is provided.
For solving the technical problem of above-mentioned existence, the utility model is achieved by following technical proposals:
The utility model comprises plug, anti-overflow net and fixed cover.One cavity is arranged, built-in fixed cover in the described plug; Described anti-overflow net is the planar shaped net, is placed horizontally between plug and the fixed cover.When the electrolysis hydrorrhea in the storage battery is online to anti-overflow,, stop electrolyte outwards to overflow because capillary effect forms one deck liquid film on the net at anti-overflow.
Compared with prior art, the utility model has following beneficial effect: be difficult for overflowing electrolyte, the reliability height.
Description of drawings
Structural representation of the present utility model is as shown in drawings:
Fig. 1 is the cutaway view of embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
The utility model comprises plug 1, anti-overflow net 2 and fixed cover 3.In the described plug 1 cavity is arranged, described fixed cover 3 is coaxial to be placed in the cavity of plug 1; Anti-overflow net 2 is planar shaped nets made from composite fibre materials, is placed horizontally between plug 1 and the fixed cover 3.
After being placed on the storage battery according to the battery cap that the utility model proposes, when the electrolyte in the storage battery touches described anti-overflow net 2, because the surface tension effects of electrolyte liquid, electrolyte forms one deck liquid film on anti-overflow net 2, this liquid film will stop electrolyte to overflow by battery cap; The gas that produces in the storage battery then is easy to through discharging the air vent hole of mesh from plug 1 on the anti-overflow net 2.The utility model has solved prior art and has been difficult for guaranteeing simultaneously gaseous emission and this technical barrier of liquid seal.
Claims (2)
1, a kind of battery cap comprises plug (1), anti-overflow net (2) and fixed cover (3), it is characterized in that described plug has a cavity in (1), and described anti-overflow net (2) places in the cavity of plug (1).
2, battery cap according to claim 1 is characterized in that, described fixed cover (3) places in the cavity of plug (1).
