The utility model content:

Technical problem to be solved in the utility model provides a kind of accumulator protecting box, and it can reduce erosion, the pollution of dust to storage battery, helps people to understand the degree of depth of electrolyte in the storage battery at any time.

Technology solution of the present utility model is:

The accumulator protecting box, it comprises a box body that is used to place storage battery, and a lid that covers on box body, has ventilative road on box body and the lid.

Described lid screw is connected on the box body.

Described lid is hinged on the box body.

The lower surface of described lid has groove and forms ventilative road or have venthole on box body and form ventilative road.

Described liquid level gauge is fixed on the surface of lid, and the bottom of liquid level gauge is stretched in the accumulator housing from the fill orifice of storage battery.

On the described box body socket is installed, two electric connecting terminals of socket are connected electrically in respectively on the positive and negative electrode of storage battery, and two electric connecting terminal leads of voltmeter are connected on the positive and negative electrode of storage battery.

On the described box body switch is installed, switch is installed on the electric loop of socket and storage battery.

Described lid is provided with preformed hole, and the positive and negative electrode of storage battery stretches out lid from this preformed hole, is fastening the perspex lid on the top of this preformed hole, and this plastic cover and lid are hinged.

Outstanding effect of the present utility model is:

1), the utility model with storage battery and dust by box body, lid is isolated comes, and exempts the pollution that storage battery is subjected to dust, prolongs the useful life of storage battery.

2), the lid blocks dust enters in the accumulator housing by fill orifice, and reduces storage battery energy.

3), liquid level gauge has been installed, can understand the degree of depth of electrolyte in the storage battery at any time, allow the user determine when to battery jar perfusion in vivo electrolyte.

4), box body is fixed tightly in the lid screw, can take convenient for maintaining at any time apart.

5), socket is installed on box body, make things convenient for user's socket of directly pegging graft just can obtain power supply from storage battery.

6), detect the voltage condition of storage battery at any time, allow people learn whether storage battery needs charging by voltmeter.

Embodiment

Embodiment 1, sees Fig. 1,3,5, the accumulator protecting box, and it comprises a box body 2 that is used to place storage battery 1, and a lid 3 that covers on box body 2, has ventilative road on box body 2 and the lid 3.

Described lid 3 screws 7 are fixedly connected on the box body 2.

The lower surface of described lid 3 has and has the ventilative road of venthole 21 formation on groove 32 and the box body 2.

Described liquid level gauge 4 is fixed on the surface of lid 3, and the bottom of liquid level gauge 4 is stretched in the accumulator housing from the fill orifice 12 of storage battery.

On the described box body 2 socket 5 is installed, two electric connecting terminals of socket 5 are connected electrically in respectively on the positive and negative electrode 11 of storage battery 1, and two electric connecting terminal leads of voltmeter 8 are connected on the positive and negative electrode 11 of storage battery 1.

On the described box body 2 switch 6 is installed, switch 6 is installed on the electric loop of socket 5 and storage battery 1.

Described lid 3 is provided with preformed hole 31, and the positive and negative electrode 11 of storage battery 1 stretches out lid 3 from this preformed hole 31, is fastening perspex lid 9 on the top of this preformed hole 31, and this plastic cover 9 is hinged with lid 3.

Operation principle: the utility model by box body 2, lid 3 isolated coming, is exempted the pollution that storage battery 1 is subjected to dust with storage battery 1 and dust, prolongs the useful life of storage battery.Lid 3 blocks dust enter in storage battery 1 housing by fill orifice 12, and reduce storage battery energy.Liquid level gauge 4 has been installed, can have been understood the degree of depth of electrolyte in the storage battery 1 at any time, allowed the user determine when in storage battery 1 housing, pour into electrolyte.Box body 2 is fixed tightly in lid 3 screws 7, can take convenient for maintaining at any time apart.Socket 5 is installed on box body 2, makes things convenient for user's socket 5 of directly pegging graft just can obtain power supply from storage battery 1.The lower surface of lid 3 has groove 32 when being convenient to charge, and the hydrogen, the oxygen that produce from storage battery 1 are separated out.Voltmeter 8 can allow people learn at any time whether storage battery needs charging.Plastic cover 9 can protect storage battery positive and negative electrode 11 to avoid rain erosion and get rusty.
