Abstract
The utility model discloses a door lock, and belongs to the field of embedded door locks. The door lock comprises an outer lock body and an inner lock body, wherein a key hole is formed in the outer lock body, a light intensity sensor and an indicator lamp are further arranged on the outer lock body, the indicator lamp comprises four LEDs which are arranged on the circumference of the key hole to form a cross shape, the light intensity sensor is connected with the four LEDs through a microprocessor in the inner lock body, and a power supply is arranged in the inner lock body. According to the door lock, the indicator lamp can be lightened when the external light rays are dim so that the door lock can be used for assisting a user in rapidly finding the key hole and opening a door, and the door lock is novel in structure and design and practical in function.
Description
Technical field
The utility model relates to a kind of door lock, belongs to embedded door lock field.
Background technology
Door lock is divided into several forms, has external hanging type, embedded and more advanced electronic lock, and the embedded door lock of being furnished with key is the most common.
People go home conventionally to need to turn the key in the lock, bright and clear by day, people can be inserted into key soon very much in the keyhole of lock and open the door, but at night, if not illumination (dark surrounds) of doorway, people cannot find keyhole very soon, with mobile phone, throw light on, slowly gropingly key is inserted to keyhole, making to open the door becomes cumbersome, has delayed the time.
Utility model content
The purpose of this utility model is: propose a kind of door lock with keyhole deixis.
This door lock comprises lock ectosome and lock endosome, and described lock ectosome is provided with keyhole, on described lock ectosome, is also provided with light intensity sensor and indicator lamp, and described light intensity sensor is connected with indicator lamp by the microprocessor in lock endosome, in described lock endosome, is provided with power supply.
Further, described indicator lamp comprises four LED, and described four LED are cross and are arranged on around keyhole.
Further, described power acquisition battery.
Technique effect:
1, can when doorway light is darker, make people find rapidly keyhole to open the door, save the time.
2, indicator lamp adopts sensor automatically to control, and uses easily, and can save electric energy.
3, structure design is novel, is easy to realize, and practical function, is especially applicable to gate at home and uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure title: 1, lock ectosome; 2, keyhole; 3, light intensity sensor; 4, indicator lamp.
The specific embodiment
Below the utility model is described in further detail.
The structure of the utility model door lock as shown in Figure 1, comprise lock ectosome 1 and lock endosome, described lock ectosome 1 is provided with keyhole 2, on lock ectosome 1, be also provided with light intensity sensor 3 and indicator lamp 4, described light intensity sensor 3 is connected with indicator lamp 4 by the microprocessor in lock endosome, in lock endosome, is provided with power supply.
The part that lock ectosome 1 is exposed for embedded door lock, the internal construction that lock endosome is locked, locks ectosome 1 here and mainly refers to the metal locking face on door body.Keyhole 2 is cross key hole, is provided with the induction mouth of light intensity sensor 3 above keyhole 2, and light intensity sensor 3 adopts the TSL2560 light intensity digit chip of TAOS company, and the microprocessor in lock endosome adopts 51 series monolithics to realize; Indicator lamp 4 comprises four LED light, and these four LED are cross and are arranged on keyhole 2 around, by single-chip microcomputer, by LED drive circuit, are controlled and are lighted; Power acquisition is located in battery case with battery.
During use, the real-time detecting gate UV light of light intensity sensor is strong and weak, and reach single-chip microcomputer and process, when responding to light intensity value lower than threshold value, four LED of Single-chip Controlling light, and point out out in the dark the position of keyhole, are convenient to people and insert key, when to daytime (influence value is more than or equal to threshold value), single-chip microcomputer cuts out LED automatically.
Claims (3)
1. a door lock, comprise lock ectosome (1) and lock endosome, described lock ectosome (1) is provided with keyhole (2), it is characterized in that: on described lock ectosome (1), be also provided with light intensity sensor (3) and indicator lamp (4), described light intensity sensor (3) is connected with indicator lamp (4) by the microprocessor in lock endosome, in described lock endosome, is provided with power supply.
