Abstract

The utility model relates to an illuminative key which comprises a key body. A light emitting diode is arranged in the front end of the key body; the back end of the key body is provided with a push switch and a battery; the battery, the push switch and a light emitting diode circuit are connected for forming a series circuit; the battery is a dismountable electronic battery; the back end of the key body is also provided with a rotatable cover; and the battery is hidden in the key body through being covered by the cover. Because the light emitting diode is arranged in the front end of the key, the light emitting diode can give out light after the push button is pressed down, and light rays can be sent out from the front end of the key. When the key is used in darkness, the front place can be illuminated, and people can clearly see a lockhole, so the lock can be conveniently unlocked. The utility model has the advantages of simple structure and convenient use, and is worth of popularized application.

Description

A kind of key that throws light on

Technical field

The key that the utility model relates to, particularly be a kind of key that can throw light on.

Background technology

Illuminating lamp is not generally installed in existing esidential building building in the corridor, the resident opened the door in the dark night, because eyes be cannot see the lockhole of door lock, often makes the key can not very fast insertion lockhole, gropes with hand, wastes time, and is very inconvenient.Though there is miniature torch to sell on the market, owing to separate with key, being used for that night illumination opens the door must the both hands operation, promptly uses an adept electric lighting of hand, opens the door by key with the another hand, seems very inconvenient in many cases.

Summary of the invention

The utility model has overcome above-mentioned shortcoming, and provide a kind of can be with door key combination and one, and can singlehanded can finish the key that throws light on of illumination and unlocking action, simple in structure, easy to use.

To achieve these goals, the utility model is to realize by the following technical solutions:

A kind of key that throws light on comprises key body, it is characterized in that, in described key body front end, light emitting diode is installed, described key body tail end is equipped with press button and battery, and described battery, press button and diode circuit are connected, and constitutes a series connection circuit.

According to above-mentioned described a kind of key that throws light on, wherein, described battery is dismountable miniature electronic battery, makes things convenient for the replacing of battery.

According to above-mentioned described a kind of key that throws light on, wherein, also be provided with a rotatable lid on the described key body rear end, described battery is covered in key body by lid, makes battery not be exposed on the external world.

The utility model presses the button switch owing in the front end of key light emitting diode is set, and the light emitting diode electrified light emitting appears light from the front end of key, and at night, when dark place uses key, but the lockhole direction is seen in direct lighting the place ahead clearly, the convenient unlatching.The utlity model has advantage simple in structure, easy to use, be worth of widely use.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.

With reference to figure 1, a kind of key that throws light on of the present utility model, it comprises key body 1, battery 4, press button 2 and Light-Emitting Diode 3; The highlighted light emitting diode 3 of low pressure is installed in key body 1 front end, and this light emitting diode 3 places in the key body 1, but does not hinder key unlocking, and is convenient to shine the place ahead of key; Press button 2 is installed in rear end at key body 1, and this press button 2 is controlled the luminous, easy to use of light emitting diodes 3.In the utility model, can also be installed in a side of key body 1 rear end at press button 2, can a hand control light emitting diode 3 when conveniently unblanking.

In the utility model, on key body 1 rear end miniature electronic cell 4 is installed also, this electronic cell 4 covers up by a rotatable insulation lid 5, makes it not be exposed to the external world.Circuit connects between described battery 4, press button 2 and the Light-Emitting Diode 3, thereby constitutes a series circuit; This light emitting diode 3 passes in the key body with between battery 4 and the press button 2 by lead and is connected.

When the utility model opens the door lock at night in the dark, as long as pin press button 2 with the thumb or the forefinger of a hand, the press button 2 that perhaps utilizes the palm of the hand to pin to be positioned at key tail, can make light emitting diode 3 electrified light emittings, illuminate the door lock lockhole of front, because key and torch one so can very fast key be inserted in the illuminated lockhole with the same hand, are finished unlocking action.When dead battery, get final product uncap, change battery, conveniently reuse.

The utility model presses the button switch 2, light emitting diode 3 electrified light emittings because light emitting diode 3 is set in the front end of key, appear light from the front end of key, at night, when dark place uses key, but direct lighting the place ahead, see the lockhole direction clearly, the convenient unlatching.The utlity model has advantage simple in structure, easy to use, be worth of widely use.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims

1, a kind of key that throws light on, comprise key body, it is characterized in that, in described key body front end light emitting diode is installed, described key body rear end is equipped with press button and battery, and described battery, press button and diode circuit are connected, constitute a series connection circuit, described battery is dismountable electronic cell, also is provided with a rotatable lid on the described key body rear end, and described battery is covered in key body by lid.
