Description

Illuminating lamp on key

The utility model belongs to the key improvement technology of unblanking.

The key that present common mechanical iron sheet lock is adopted is all aluminium sheet or copper coin is made, one end is the handle of holding of garden shape, one end is the end of unblanking that has different grooves and dialing spring breach, what have is copper material, the aluminum material that has, and its advantage is made simple, the punching press one-shot forming, weak point is not have on the key lighting device is arranged, and the difficulty of unblanking night is used inconvenience.

For solving the deficiency of above key, the purpose of the utility model provides a kind of key illuminating lamp, is furnished with this illuminating lamp on the key general, has effectively solved the problem of unblanking inconvenience night.

Structure design of the present utility model is achieved in that in flat key handle end one side illuminating lamp is housed, its detailed structure is that the outside is a flat plastic casing, in housing, be placed with two button cells side by side, a positive pole upwards, a negative pole upwards, key switch is housed in the middle of the battery, be placed with the shunt contact of two batteries under the switch, return spring is housed on switch simultaneously, be fixed with illuminating lamp to the front in the housing, be light emitting diode, diode two limbs be pressed in respectively two batteries below, whole housing is fixed on the locating hole of key, switch pushes button during use, illuminating lamp is shinny, and unblank night easy to use.

Detailed structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is a key structure of the lighting lamp schematic diagram;

Fig. 2 is a key illuminating lamp orthographic drawing.

Its structure is by shown in Figure 1,1 is key body, is fixed with plastic casing 2 on body 1, and two batteries 3 are housed in housing 2, a positive pole upwards, another negative pole makes progress, and middle 4 is key switch, and switch 4 following 6 is a shunt contact, 5 is light emitting diode, its limb be placed on battery 3 below, 7 is keyhole, 8 is the locating hole of stationary housing.

Advantage of the present utility model: simple in structure, fit on the key night lighting, easy to use, can be fixed on various unblanking and use on the key.
