Description

Lighting key

The utility model relates to a kind of illuminating key, the particularly a kind of illuminating key that can open door lock under condition is understood in the without a licence at night.

At present, common key itself does not have the illumination device, and door lock that some will be opened in the dark or bicycle, automobile, lock for motorcycle bring difficulty to people.

The purpose of this utility model is that a kind of automatic light source and the atomic illuminating key of power consumption will be provided, and does not have the problem that undoes the lock under the light source condition at night to solve people.

The purpose of this utility model is achieved in that

The utility model is by key, light emitting diode, button cell, compositions such as miniature key switch, wherein illumination box is by last, lower box body is formed, the afterbody of lower box body and key bonds together, the afterbody of lower box body has the circular trough of two dress button cells, each rounded trough bottom respectively is bonded with the circular copper sheet of a band contact, the both sides of the front end key of lower box body are bonded with light emitting diode (or miniature miniature bulb) and miniature key switch respectively, upper cartridge body is equipped with an opening in miniature key switch corresponding positions, the button of miniature key switch places in this opening, on, lower box body is fixed by screw-nut.

The utility model is simple in structure, volume is little, has power consumptive province, the life-span is long, cost is low, easy to carry advantage, but also double as low-light illumination has practical value, is applicable to all kinds of keys, and only need press key button can be luminous, very easy to use.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 7 is a circuit diagram of the present utility model.

Among the figure: 1, key, 2,2 ', installing hole, 3, miniature key switch, 4, lack contact, 5, circular copper sheet, 6, circular trough, 7, long contact, 8,8 ', installing hole, 9, circular copper sheet, 10, lower box body, 11, light emitting diode, 12, opening, 13,14, button cell, 15, upper cartridge body, 16, circular trough.

See Fig. 1, the lower box body 10 of illumination box bonds together with the afterbody of key 1, the afterbody of lower box body 10 has two circular troughs 6,16, the circular copper sheet 9(that circular trough 16 bottoms are bonded with a belt length contact 7 sees Fig. 2), the circular copper sheet 5(that the bottom of another circular trough 6 is bonded with a short contact 4 of band sees Fig. 4), the both sides of the front end key of lower box body 10 are bonded with luminous two pipe 11 and miniature key switch 3 respectively, two button cells 13,14 are placed on two circular troughs 6 of lower box body 10 respectively, in 16, negative pole respectively with circular copper sheet 5,9 contacts, the positive pole of button cell 14 contacts with the pipe leg of light emitting diode, the positive pole of button cell 13 contacts with the long contact 7 of circular copper sheet 9, and another pipe leg of light emitting diode and the short contact 4 of circular copper sheet 5 connect the miniature two ends that connect key swich 3 respectively.

See Fig. 6, the corresponding positions of the miniature key switch 3 of the upper cartridge body 15 of illumination box in lower box body 10 is equipped with an opening 12, the button of miniature key switch places in this opening, upper and lower box body 15,10 is by installing hole 2,2 ', fix with screw-nut with 8,8 ', simultaneously button cell is fixedly clamped.Unclamp screw, opening upper and lower box body is replaceable button cell.

Upper and lower box body is that transparent plastic is made, and miniature key switch is optional with the switch on the calculator, and the also available miniature miniature bulb of light emitting diode replaces.

Claims (2)
