Abstract

The utility model discloses a battery converter, which is characterized in that one end of a cylindrical housing of the battery converter is open, while the other end is closed; a conductive strip is arranged at the closed end; a metal spring is fixed on the inner side of the conductive strip; at least three reinforcing plates are radially fixed on the inner side of a sidewall of the cylindrical housing; a space is formed between every two reinforcing plates to hold at least one dry battery. The utility model has the advantages of simple structure, low manufacturing cost, reduced weight of the flash light without changing the housing size of the flash light since the AA or AAA battery is converted into D battery and the D battery used for the flash light is converted into AA or AAA battery and reduced consumption cost of the battery.

Description

Battery converter

Technical field

The utility model relates to and a kind of small cell is converted to the Battery converter that the large size battery size uses.

Background technology

The electronic product of the movable type that daily lifes such as old-fashioned flashlight, portable electricity-saving lamp are used usually uses the large size battery as power supply.Along with the development of led technology, because it saves advantages such as electric energy, long service life, light-emitting diode obtains more and more widely application as light emitting source in this electronic product.Because the light-emitting diode power consumption is few, only need No.5 cell or No. seven batteries to get final product when in flashlight, using.But if use No.5 cell or No. seven batteries, the handle of flashlight must be done more tinyly, holds inconvenience.

The utility model content

The purpose of this utility model will provide a kind of Battery converter exactly, and the size that No. five or No. seven batteries is converted to the large size battery is used.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: the shell of Battery converter is that one one end is an openend, and the other end is the cylindrical outer casing of blind end; This blind end is a conducting strip, and this conducting strip inboard is fixed with a metal spring; The cylindrical outer casing inside sidewalls is fixed with at least three gussets radially, forms the space that can hold at least one dry cell in the middle of each gusset.

For dry cell can be fixed in the cylindrical outer casing preferably, as a kind of improvement, described cylindrical outer casing inside sidewalls is fixed with at least three flexure strips radially, and the elastic tip of each flexure strip extends in the described space that holds dry cell.

As a kind of improvement, described metal spring places in the spring protection cover, and the free end of metal spring stretches out outside the cover.

The summation of the height of described spring protection cover and the height of No.5 cell equals the height of cylindrical outer casing.

The external diameter of described cylindrical outer casing equals the external diameter of large size battery, and the diameter in each formed space of gusset equals the external diameter of No.5 cell or No. seven batteries.

As preferred version, the height of described cylindrical outer casing equals the height of a large size battery.

No. five or No. seven batteries are inserted in the space that forms between each gusset in the Battery converter, and negative pole inwards, and is outwards anodal, promptly converts a large size battery to, uses for electronic products such as flashlights.Certainly, if do longly, can vertically place two or three No. five or No. seven dry cells to the Battery converter shell.

The utility model is simple in structure, low cost of manufacture, dexterously No. five or No. seven batteries are become the large size battery, must use script the flashlight of large size dry cell to become can use No. five or No. seven batteries, under the prerequisite that does not change the flashlight shell size, alleviate the weight of flashlight, saved the battery use cost again.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

As shown in Figure 1, 2, 3, the shell 1 of Battery converter is cylindric, and an end is an openend, and the other end is a blind end, and the diameter of shell 1 is suitable with the shell of a large size dry cell with height; Blind end is a conducting strip 2, and conducting strip can be fixedly connected by chimeric or alternate manner and shell; The inboard of conducting strip is fixed with a metal spring 3; The inside sidewalls of shell is fixed with three gussets 4 and three flexure strips 5 radially, and gusset 4 and flexure strip 5 distribute alternately; Form in the middle of each gusset 4 and the flexure strip 5 one can hold No. five or No. seven batteries the space.The blind end of shell also has a spring protection cover 6; this spring protection cover 6 is positioned at metal spring 3 peripheries; the free height of the aspect ratio metal spring 3 of spring protection cover 6 is low slightly; the free end of metal spring 3 stretches out outside the cover, and the summation of the height of spring protection cover 6 and the height of No. five or No. seven batteries just equals the height of cylindrical outer casing 1.

As Fig. 4, shown in Figure 5, during use, in the space that No. five or No. seven dry cells 7 are inserted between each gusset and the flexure strip, the negative pole of dry cell contacts with metal spring 3, anodal openend from shell 1 stretches out, and promptly becomes a dry cell identical with large size dry cell overall dimension for using.
