Abstract
The utility model discloses a screw plug for an accumulator, in particular to a ventilating screw plug provided on an acid lead accumulator, consisting of a screw plug lid, a screw plug body, and a plastic tab. The lower part of the screw plug body is provided with screw threads, and the upper part of the screw plug body is connected with the screw plug lid. A guide hole is arranged in the screw plug body, and the plastic tab is adhered on the screw plug body at the position of the guide hole. A plurality of micropores are opened on the plastic tab, and a ventilating groove is arranged between the screw plug lid and the screw plug body. Gas can be exhausted through the guide hole, the micropores, and the ventilating groove while in use, but liquid can not. The utility model has the advantages of improving the liquid retentivity of the accumulator and reducing the pollution to environment. Besides, the structure is simple, and the cost is low.
Description
Technical field:
The utility model relates to a kind of plug screw that is used for storage battery, especially breathable plug screw on the lead plumbate storage battery.
The cavity volume that several loading electrolytes are arranged in the lead plumbate storage battery all is provided with liquid filling hole on each cavity volume, be rotary with plug screw on liquid filling hole, and the plug screw of outwarding winding can add electrolyte.Because storage battery can produce gas when impulse electricity, the gas that produces for making is in time discharged, existing short-cut method is a ventilative aperture of opening one 2 millimeter on plug screw, but in use the problem of Cun Zaiing is that acid solution that is spilt by ventilative aperture and the acid mist of emerging pollute the environment, etching apparatus, and the electrolyte that spills can't reclaim, so make guarantor's fluidity of storage battery poor, needs frequent liquid feeding.For addressing the above problem the water collector that also has the people on water inlet, to adorn a labyrinth type, as electrolyte ventilative and that recovery spills, though this method has the recovery effect to the electrolyte that spills that jolts because of vehicle, but in fact utilize the labyrinth only to prolong ventilative path, do not change the present situation that outside air and cavity volume directly communicate, so in case side falls electrolyte and can flow out, the heating acid mist pollution environment of can emerging during impulse electricity, and also manufacturing cost is higher.
Summary of the invention:
The purpose of this utility model provides a kind of plug screw that is used for storage battery, and it has the effect of ventilative blocking solution, can improve guarantor's fluidity of storage battery, overcomes the pollution of acid solution acid mist to environment, and simple in structure, cost is low.
The utility model comprises the plug screw lid, it is characterized in that: also comprise plug and plastic tab, have the screw thread that is complementary with the storage battery liquid filling hole on the external diameter of plug lower end, its upper end external diameter is connected with the plug screw lid, have guide hole in the plug, plastic tab is bonded on the plug at guide hole place, has a large amount of micropores on plastic tab, has ventilating groove between plug screw lid and plug.In the use, gas is discharged through the guide hole of plug, the micropore of plastic tab and the ventilating groove between plug screw lid and the plug, and liquid is owing to the effect of micropore can not be discharged.
The thickness of above-mentioned plastic tab is the 0.3-1.2 millimeter, and micro-pore diameter is the 0.0005-0.002 micron.
The utility model is owing to adopted the structure that has a large amount of micropores on plastic tab, gas can freely be come in and gone out, liquid then can not pass through, and has solved the present situation that outside air and cavity volume directly communicate, thereby improved guarantor's fluidity of storage battery, eliminated because of of the pollution of acid solution acid mist to environment.Through test, storage battery in use need not to add electrolyte.In addition, the utility model also has advantage easily manufactured, that cost is low.
Embodiment:
Provide embodiment of the present utility model and accompanying drawing below, and be described further:
Fig. 1, be main cut-away view of the present utility model.
By shown in Figure 1, the utility model is by 3 groups of plug screw lid 2, plug 1 and plastic tabs Become. Have the screw thread 5 that is complementary with the accumulator liquid feeding hole on the plug 1 lower end external diameter, on it The end external diameter is connected with plug screw lid 2, has guide hole 6 in the plug 1, and plastic tab 3 is bonding On the plug 1 at guide hole 6 places. The thickness of plastic tab 3 is the 0.3-1.2 millimeter, is moulding Having a large amount of diameters on the material thin slice 3 is 0.0005-0.002 micron micropore 7. At plug screw lid 2 And have ventilating groove 4 between the plug 1. During use, fixing by the screw thread 5 of plug 1 On the liquid filling hole of battery, then gas can be through micropore 7 and the plug screw lid 2 of plastic tab 3 And 4 discharges of the ventilating groove between the plug 1, and liquid is owing to the effect of micropore 7 can not be discharged. For anticorrosive, above-mentioned plug screw lid 2, plug 1 form by plastic injection-moulded. Be simplified structure, Plug 1 and plastic tab 3 also can pass through two shot process, form one.
