Abstract

The utility model discloses a chargeable electric torch, comprising a lamp cap, a housing, a switch, and an accumulator, wherein, a metal conductive rod 4 is arranged on the switch 3, the conductive rod 4 can be contacted with two metal conductive sheets 5 by an ON position, the conductive rod can be disengaged from the metal conductive sheets by an OFF position, one conductive sheet is connected with a bulb base 10, the other conductive sheet is connected with a negative pole of the accumulator, and the bulb base 10 can be a metal and helical torsional spring.

Description

Chargeable electric torch

The utility model is relevant with flashlight.

Existing flashlight switch contacts the back and connects power supply with an elastic sheet metal, though simple in structure, poor durability is used and thousands ofly just broken down after inferior.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.

The purpose of this utility model provides a kind of simple in structure, and is easy to use, and switch is durable, the chargeable electric torch of school light sensitivity.

The utility model is achieved in that

Chargeable electric torch, comprise lamp holder, housing, switch, the charger battery has metal conductive bar 4 on the switch 3, its position of opening can make contact rod 4 contact with two metallic conduction sheets 5, the position of its pass can make contact rod and metallic conduction sheet break away from, and a conducting strip is connected with bulb seat 10, and a conducting strip is connected with battery terminal negative.

Tube face 10 of the present utility model 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 height of metal conductive bar and two metallic conduction sheets to close mode, and is simple in structure, long service life, and switch does not break down for tens thousand of times.Lamp holder is an external screw thread, and the torch housing is the front focus school photo structure of internal thread, and 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 the I place 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, contact, metallic conduction sheet 5B 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, by bulb connection battery positive voltage formation loop.When switch 3 was in open position, the two ends of contact rod 4 closely contacted with the metallic conduction sheet, formed the loop.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.
