Abstract

The utility model discloses a light regulating and charging device for flashlights, which is composed of elements such as a battery container, a rotary linked switch, a turn knob, a charging socket, a flashlight cover, a diode, a luminescent diode for indicating wrong phases, a luminescent diode of an external power supply, a resistor, etc. The light regulating and charging device for flashlights has the advantages of capability of changing a common flashlight into the light regulating and charging flashlight, simple structure, low cost, convenient operation, etc. When the light regulating and charging device for flashlights is used, the utility model is placed into the flashlight, the flashlight cover is covered, a flashlight switch is switched on, and the turn knob is rotated, and then the common flashlight is caused to change the light. An output plug of a charging transformer is inserted on the socket so as to charge for a battery unit inside the flashlight.

Description

Flashlight light modulation and charger

The utility model relates to the light modulation used on a kind of flashlight and the electrical equipment of charging, belongs to flashlight accessory field.

At present, commonly used flashlight in the prior art, its shortcoming is can not light modulation and its battery charged, thereby very inconvenient when using, and the flashlight that some can light modulation, but because of complex structure, cost an arm and a leg and can not generally be accepted by people.

The purpose of this utility model is: a kind of flashlight light modulation and charger simple in structure, cheap, that also can make common flashlight change over light modulation and can charge are provided.

The utility model is to constitute like this: it is by battery case (1), rotation linked switch (2), knob (3), charging socket (4), torch lid (9), diode D1, misphase indication light emitting diode D2, external power supply light emitting diode D3, resistance R 1 and R2 form, the battery case (5) that four symmetries are arranged at battery case (1) upper edge axis direction, end at battery case (5) has battery spring (6), the other end at battery case (5) has anode contact (7), front end at battery case (1) has output electrode (8), switch (2) is installed in the rear end of battery case (1), knob (3) is installed in the rotating shaft of switch (2), socket (4) is housed on knob (3), diode D1, misphase indication light emitting diode D2, external power supply light emitting diode D3, resistance R 1 and R2, stage clip (6), contact (7), output electrode (8) all is connected with switch (2), torch lid (9) contacts with the negative pole of switch (2), R1 and D2 series connection, R2 and D3 series connection, the negative pole of R1 and D1 connects output electrode (8), the positive terminal of the positive pole of D1 and the negative pole of D2 and R2 combination hub (4), the negative pole end of the earth terminal combination hub (4) of the negative pole of D3 and stage clip (6) and switch (2).

The utility model compared with prior art, it has the advantage that can make common flashlight change over light modulation and chargeable flashlight, and has advantages such as simple in structure, cheap, easy to use.During use, the battery that can charge is put into battery case of the present utility model (5), and the utility model put into common flashlight, torch lid (9) is gone up on common torch, at this moment connect the K switch on the common torch, its lamp Q is just luminous, turning knob (3), just can make the four Battery pack group E that are contained in the battery case (5) change over three kinds of connection status of connecting after the in parallel or two groups of parallel connections of four groups of series connection or four groups respectively, thereby make the lamp Q of common torch send the light of different brightness; The output plug of charging transformer directly is inserted on the socket (4), and D3 is bright, promptly the battery pack in the torch is charged, and when the electric power polarity of charging transformer plug connects inverse time, D2 is just luminous for misphase indication light emitting diode, at this moment only needs its polarity transferred to get final product.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1;

Accompanying drawing 3 is circuit theory diagrams of the present utility model.

Embodiment of the present utility model: battery case (1), knob (3) adopts plastics or other insulating materials to make, two layers of third gear, the 24 angle band switches that rotation linked switch (2) adopts market to sell, charging socket (4), diode D1, misphase indication light emitting diode D2, external power supply light emitting diode D3, the finished product that resistance R 1 and R2 all adopt market to sell, torch lid (9) can be according to using the torch with different size to join work, produce the battery case (5) of four symmetries at battery case (1) upper edge axis direction, adorn a battery spring (6) and anode contact (7) respectively at the two ends of each battery case (5), front end at battery case (1) is installed an output electrode (8), switch (2) is installed in the rear end of battery case (1), knob (3) is installed in the rotating shaft of switch (2), on knob (3), load onto socket (4), diode D1, light emitting diode D2 and D3, resistance R 1 and R2, with stage clip (6), contact (7), output electrode (8) all is connected with switch (2), make them when rotating switch (2), can change over three kinds of connection status of connecting after the in parallel or two groups of parallel connections of four groups of series connection or four groups respectively with being contained in four Battery pack group E in the battery case (5), torch lid (9) is contacted with the negative pole of switch (2), R1 and D2 series connection, R2 and D3 series connection, the negative pole of R1 and D1 connects output electrode (8), the positive terminal of the positive pole of D1 and the negative pole of D2 and R2 combination hub (4), the negative pole end of the earth terminal combination hub (4) of the negative pole of D3 and stage clip (6) and switch (2).
