Abstract

The utility model discloses a charge type electric torch with changeable light, comprising a lamp cap, a housing, a switch, a voltage reduction element, a charger, and an accumulator, wherein, a metal conducting rod 4 is arranged on the switch 3, both ends of the conducting rod 4 can be caused to be contacted with metal conducting sheets 5A and 5B close by an ON position, and both ends of the conducting rod 4 can be caused to be contacted with the metal conducting sheets 5A, 5B, and 5C simultaneously and close by another ON position; the voltage reduction element R is connected between the conducting sheets 5B and 5C, and the conducting rod and the metal conducting sheets can be caused to be disengaged by an OFF position of the switch 3; the conducting sheet 5A is connected with a negative pole of the accumulator. The conducting sheet 5C is connected with a bulb base 10. The switch 3 is in different ON positions. The change of strong and weak light can be realized.

Description

The variable light chargeable electric torch

The utility model is relevant with flashlight.

Existing flashlight switch contacts the back and connects power supply with elastic sheet metal, though simple in structure, poor durability, just break down after using thousands of times, existing torch front focus school photo structure is realized by the rotation lamp holder, but it is insensitive to regulate school light, and slide shakes during focusing.

Existing flashlight does not have the light of change function, and bulb is worked under high voltage for a long time, and bulb life is short.

The purpose of this utility model provides a kind of simple in structure, and is easy to use, and switch is durable, and school light sensitivity has the light of change function, can improve the variable light chargeable electric torch of bulb service life greatly.

The utility model is achieved in that

The utility model comprises lamp holder, housing, switch, voltage drop element, charger, battery, metal conductive bar 4 is arranged on the switch 3, and an one position of opening can make contact rod 4 two ends and

metallic conduction sheet

5A, and 5B closely contacts, another position of opening can make the two ends and the metallic conduction sheet 5A of contact rod 4,5C is closely contact simultaneously, is connected with voltage drop element R between conducting strip 5B and the 5C, and the position that switch 3 closes can make contact rod and metallic conduction sheet break away from, conducting strip 5A is connected with battery terminal negative, and conducting strip 5C is connected with tube face 10.

The utility model tube face 10 is the metal spiral torsion spring, and bulb 11 has screw thread to cooperate with torsion spring 10.

The screw-internal thread fit of the external screw thread of lamp holder 1 of the present utility model and housing 2, slide 13 is connected with lamp holder 1 with reflector 12.

The fixedly torsion spring shape tube face of bulb directly has been installed on the lamp socket of the present utility model, and switch adopts the clutch mode of metal conductive bar and 3 metallic conduction sheets, and is simple in structure, long service life, and switch does not break down for tens thousand of times.And can make and obtain two kinds of voltages on the bulb, realize becoming light, can prolong bulb life greatly.Lamp holder is an external screw thread, and the front focus school photo structure that electric simple housing is an internal thread is simple in structure, and luminous sensitivity is convenient.

Following is accompanying drawing of the present utility model:

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is the switch junctions composition.

Fig. 3 is the C-C cutaway view of Fig. 2.

Fig. 4 is reduction voltage circuit figure.

Fig. 5 is 1 place's partial enlarged drawing of Fig. 1.

Following is embodiment of the present utility model:

Torch housing 2 front ends and lamp holder 1 threaded engagement.Chute on the housing 2 cooperates with switch 3.Switch has protruding seat for 3 times, and metal conductive bar 4 is installed on it.The two ends of contact rod 4 respectively with

metallic conduction sheet

5A, 5B, 5C contact, 5B is connected with voltage drop element R between the 5C, metallic conduction sheet 5C is connected with metal torsion spring 10, the metal torsion spring is fixed on that battery terminal negative is connected with metallic conduction sheet 5A on the lamp socket 6, connects battery positive voltage by bulb and forms the loop.When switch 3 was in low light level open position, the two ends of contact rod 4 closely contacted with

metallic conduction sheet

5A, 5B, and electric current is by conducting strip 5B, voltage drop element R, and conducting strip 5C forms the loop.Switch 3 pushes away forward again, and contact rod 4 simultaneously when contacting

metal conducting strip

5A, 5B, 5C, voltage drop element is ineffective, and obtain full voltage on the bulb this moment, produces high light.Switch is at the dotted line position of Fig. 3, and contact rod 4 disengages with the metallic conduction sheet, opens circuit.Lamp holder 1 adopts externally threaded plastic products, and the anterior plastic products that adopt internal thread of torch housing can change focus point between bulb 11 and the reflector 12 by rotation lamp holder 1, thereby reaches the purpose of school light.There is charging to show light emitting diode 7 and charging plug 8.
