Abstract
The utility model discloses a top cover of a lead acid storage battery, which belongs to the field of storage batteries, and solves the problem that an existing storage battery safety valve is difficult to open. The top cover of the lead acid storage battery is characterized in that the surface of the top cover is provided with a plurality of filling nozzles, each filling nozzle is provided with an annular groove which is matched with a safety valve, each filling nozzle comprises an inner hole, the annular groove is formed in the outer circumference of the inner hole, a barrel is formed between each annular groove and each inner hole, and the upper end surface of the barrel is provided with a groove. The groove is additionally formed in the upper edge of the wall of the inner hole of the filing nozzle, so that the contact area between the gas discharged from the inner hole of the storage battery and the safety valve is increased, the pressure on the safety valve is increased, and the safety valve can be successfully and automatically opened when the gas reaches a given pressure.
Description
Technical field
The utility model relates to storage battery field, particularly a kind of top cover for lead-acid accumulator.
Background technology
Electric boosted automobile-used lead acid accumulator has a small amount of gas in the latter stage of charging and discharges via the endoporus of liquid injecting mouth, generally meeting mounting safety valve on liquid injecting mouth, in the time that gas pressure reaches certain value, air pressure promotes safety valve and opens, thereby avoids the excessive blast causing of air pressure.
In actual production use procedure, find, only depend on the contact-making surface of endoporus and safety valve, gas pressure intensity still cannot be pushed safety valve open in the time being everlasting warning numerical value.
Summary of the invention
The object that the utility model will reach is to provide a kind of top cover for lead-acid accumulator, can increase the gas of storage battery discharge and the contact area of safety valve, the phenomenon of effectively avoiding safety valve to open.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of top cover for lead-acid accumulator, the surface of upper cover is provided with some liquid injecting mouths, each liquid injecting mouth is provided with the cannelure for coordinating safety valve, each liquid injecting mouth comprises an endoporus, cannelure is located at the periphery of endoporus, between cannelure and endoporus, forms cylindrical shell, and the upper surface of cylindrical shell is provided with groove.
Further, described groove is provided with two, and two grooves are located at the two ends of diameter of bore.Make gas because of groove increase the pressure to safety valve even.
Further, described cylindrical shell upper limb is provided with four grooves, and four grooves are uniformly-spaced arranged on the upper surface of cylindrical shell.Further make gas because of groove increase the pressure to safety valve even.
Further, the diameter of described endoporus increases from bottom to top gradually, and the bottom oral area of endoporus protrudes from the bottom surface of upper cover.The endoporus that internal diameter increases gradually from bottom to top can reduce the air pressure of the gas of discharging through endoporus.
Further, the diameter of described endoporus upper end is 9mm-10mm, and the diameter of lower end is 7mm-8mm.The acid solution of avoiding the diameter of bore of 5mm to hinder in pregnant solution kettle enters internal storage battery.
Further, all described liquid injecting mouths are all located at the upper surface of upper cover, and the end face of all liquid injecting mouths upper end is positioned at same plane.The installation of convenient and safe valve.
Further, the lower surface edge of described upper cover is evenly equipped with six projections.While keeping upper cover and below miscellaneous part to install, leave uniform gap, be convenient to epoxide-resin glue and fill, reach the object of excellent sealing.
Adopt after technique scheme, the utlity model has following advantage:
Cylindrical shell upper limb by liquid injecting mouth endoporus adds groove, increased gas that storage battery discharged by endoporus and the contact area of safety valve, thereby increased the pressure to safety valve, and while making gas reach certain pressure intensity, safety valve can be opened smoothly automatically.

Embodiment
Embodiment mono-
Fig. 1-5 are depicted as embodiment mono-of the present utility model.
A kind of top cover for lead-acid accumulator, the upper surface of upper cover is provided with six liquid injecting mouths 1, the end face of all liquid injecting mouths 1 upper end is positioned at same plane, each liquid injecting mouth 1 is equipped with a cannelure 6 for mounting safety valve, liquid injecting mouth 1 also comprises a circular endoporus 2, and cannelure 6 is located at the periphery of endoporus 2, between cannelure 6 and endoporus 2, forms annular cylindrical shell 3, cylindrical shell 3 is being provided with two grooves 4 with the upper limb of endoporus 2 upper end end face, and two grooves 4 are located on the same diameter of cylindrical shell 3.Endoporus 2 from bottom to top internal diameter increases gradually, and cylindrical shell 3 bottoms of endoporus 2 protrude from outside liquid injecting mouth 1 bottom surface, and the endoporus that internal diameter increases gradually from bottom to top can reduce the air pressure of the gas of discharging through endoporus.When after storage battery sealing, safety valve (not shown) one by one correspondence buckles on liquid injecting mouth 1, storage battery is in use inner can produce gas, groove 4 has increased gas and the contact area to safety valve, thereby increase the pressure to safety valve, while making gas reach certain pressure intensity, safety valve can be opened smoothly automatically, and symmetrical groove 4 is the stressed even of safety valve.The diameter maximum (being endoporus 2 upper ends) of endoporus 2 is 9.5mm, also can be other sizes in 9mm or 10mm or 9mm-10mm, the minimum place of diameter (being endoporus 2 lower ends) of endoporus 2 is 7.5mm, also can be other sizes in 7mm or 8mm or 7mm-8mm, the acid solution that can avoid the diameter of bore of 5mm to hinder in pregnant solution kettle enters internal storage battery.The lower surface edge of upper cover is evenly equipped with six projections 5, while keeping upper cover and below miscellaneous part to install, leaves uniform gap, is convenient to epoxide-resin glue and fills, and reaches the object of excellent sealing.
Embodiment bis-
See Fig. 6, different from embodiment mono-, the cylindrical shell 3 of the endoporus 2 of each liquid injecting mouth 1 is provided with 4, four grooves 4 of four grooves and is distributed on annular cylindrical shell 3, can further increase the contact area of groove 4 and safety valve.
