Abstract
The invention discloses a kind of Spy hole of anti-theft door, including object lens and eyepiece it is characterised in that also including electronic-control dimming glass, described electronic-control dimming glass is positioned close to one end of eyepiece, and described electronic-control dimming glass is passed through switch and is connected with drive circuit；Described electronic-control dimming glass is arranged on eyepiece near indoor one end；Described electronic-control dimming glass is LCD electric-controlled dimming glass.This opal safety coefficient is high, the antitheft anti-tampering, privacy beneficial to protection user, and low cost.
Description
Technical field
The present invention relates to antitheft door security fields, particularly to a kind of Spy hole of anti-theft door.
Background technology
Spy hole of anti-theft door is also known as peephole, it is installed in a kind of compact optical instrument on antitheft door, it is easy to resident from indoor situation about observing through opal outdoors, its structure generally includes object lens and eyepiece, object lens are arranged on the outdoor end of antitheft door, eyepiece is arranged on the indoor end of antitheft door, passes through eyepiece for indoor user, outdoor situation observed by object lens.
This opal peephole is two-way translucent cat eye, although thief not so easily sees the situation of interior clearly from objective end, but the light of interior, the change of shadow can be observed from object lens, and interior whether someone can be judged according to the situation of change of light, shadow, and then implement larceny.Traditional opal is unfavorable for protecting personal safety and proprietary safety, and is unfavorable for protecting the privacy of people.
Content of the invention
The purpose of the present invention is for the deficiencies in the prior art, and provides a kind of Spy hole of anti-theft door, and this opal safety coefficient is high, the antitheft anti-tampering, privacy beneficial to protection user, and low cost.
The technical scheme realizing the object of the invention is：
A kind of Spy hole of anti-theft door, including object lens and eyepiece, unlike the prior art, also includes electronic-control dimming glass, described electronic-control dimming glass is positioned close to one end of eyepiece, and described electronic-control dimming glass is passed through switch and is connected with drive circuit.
Described electronic-control dimming glass is arranged on eyepiece near indoor one end.
Described electronic-control dimming glass is arranged between object lens and eyepiece.
Described electronic-control dimming glass is LCD electric-controlled dimming glass.
When electronic-control dimming glass is not powered, it is in opaque impermeable light state, block the light that thief directly observes interior by opal outdoor end object lens, the situation of change of shadow, when indoor user needs to observe outdoor situation from the eyepiece end of opal, the power supply only needing to connect drive circuit is energized to electronic-control dimming glass, electronic-control dimming glass is immediately turned into transparent, the state of printing opacity, observation finishes power-off, electronic-control dimming glass recovers opaque again, lighttight state, block thief and directly observe indoor light by opal outdoor end object lens, the situation of change of shadow, can not be according to light, the situation of change of shadow judges interior whether someone, and then implement larceny, simultaneously, stranger is not because observe the situation of interior, also protect the privacy of user simultaneously.
Therefore, this opal safety coefficient is high, the antitheft anti-tampering, privacy beneficial to protection user, and low cost.
Brief description
Fig. 1 is the structural representation of embodiment 1；
Fig. 2 is the structural representation of embodiment 2.
In figure, 1. object lens 2. eyepiece 3. electronic-control dimming glass 4. drive circuit.
Specific embodiment
With reference to the accompanying drawings and examples present invention is further elaborated, but is not limitation of the invention.
Embodiment 1：
With reference to Fig. 1, a kind of Spy hole of anti-theft door, including object lens 1 and eyepiece 2, also include electronic-control dimming glass 3, described electronic-control dimming glass 3 is positioned close to one end of eyepiece 2, described electronic-control dimming glass 3 is passed through switch and is connected with drive circuit 4.
Described electronic-control dimming glass 3 is arranged on eyepiece 2 near indoor one end.
Described electronic-control dimming glass 3 is LCD electric-controlled dimming glass.
When electronic-control dimming glass 3 is not powered, it is in opaque impermeable light state；When indoor user needs to observe outdoor situation from the eyepiece end of opal, the power supply only needing to connect drive circuit 4 is energized to electronic-control dimming glass 3, electronic-control dimming glass 3 is immediately turned into transparent, printing opacity state, observation finishes power-off, and electronic-control dimming glass 3 recovers opaque, lighttight state again.
Embodiment 2：
With reference to Fig. 2, a kind of Spy hole of anti-theft door, electronic-control dimming glass 3 is arranged between object lens 1 and eyepiece 2, and remaining is with embodiment 1.
