Abstract
The utility model discloses a shadow burglary -resisting door cat eye, including objective and eyepiece, its characterized in that still includes automatically controlled light control glass and LED lamp, automatically controlled light control glass sets up in the one end of being close to the eyepiece, automatically controlled light control glass passes through the switch and is connected with drive circuit, the LED lamp is connected with random signal generator, the LED lamp sets up the periphery at automatically controlled light control glass, automatically controlled light control glass sets up and is close to indoor one end at the eyepiece, automatically controlled light control glass be the automatically controlled light control glass of liquid crystal, the LED lamp set up and to be close to indoor one end. This kind of cat eye factor of safety is high, the theftproof jam -proof, do benefit to protection user's privacy, and with low costs.
Description
Technical field
The utility model relates to security door security fields, particularly a kind of shadow Spy hole of anti-theft door.
Background technology
Spy hole of anti-theft door is also known as peephole, it is a kind of compact optical instrument be contained on security door, be convenient to resident indoor through opal observation situation outdoors, its structure generally includes object lens and eyepiece, object lens are arranged on the outdoor end of security door, eyepiece is arranged on the indoor end of security door, for the user of indoor through the situation outside eyepiece, object lens observation ward.
This opal peephole is two-way translucent cat eye, although thief is not so easily see indoor situation clearly from objective end, but indoor light, the change of shadow can be observed from object lens, and can judge whether indoor have people according to the situation of change of light, shadow, and then implement larceny.Traditional opal is unfavorable for protection personal safety and proprietary safety, and is unfavorable for the privacy protecting people.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, and provides a kind of Spy hole of anti-theft door, and this opal safety factor is high, antitheft anti-tampering, the privacy that is beneficial to protection user, and cost is low.
The technical scheme realizing the utility model object is:
A kind of shadow Spy hole of anti-theft door, comprises object lens and eyepiece, also comprises
Electronic-control dimming glass, described electronic-control dimming glass is arranged on the one end near eyepiece, and described electronic-control dimming glass is connected with drive circuit by switch;
LED, described LED is connected with random signal generator, and described LED is arranged on the periphery of electronic-control dimming glass.
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.
Described LED is arranged near indoor one end.
When electronic-control dimming glass does not power up, be in opaque light tight state, block thief and directly observe indoor light by the outdoor end object lens of opal, the situation of change of shadow, when the user of indoor needs from situation the eyepiece end observation ward of opal, the power supply connecting drive circuit is only needed to be energized to electronic-control dimming glass, electronic-control dimming glass becomes transparent immediately, the state of printing opacity, observe complete power-off, electronic-control dimming glass recovers again opaque, lighttight state, block thief directly by the light in opal outdoor end object lens observation ward, the situation of change of shadow, what make thief can not according to light, the situation of change of shadow judges whether indoor have people, and then implement larceny, in addition, the electronic-control dimming glass when light that the LED of irregular random light emission sends makes opaque presents the change of irregular light and shade, simulate the shadow change projected when indoor television set or people walk about on electronic-control dimming glass, can confuse thief, make it dare not implement larceny easily, meanwhile, stranger, because do not observe indoor situation, also protects the privacy of user simultaneously.
Therefore, this opal safety factor is high, antitheft anti-tampering, the privacy that is beneficial to protection user, and cost is low.
Accompanying drawing explanation
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 5.LED lamp 6. random signal generator.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model content is further elaborated, but is not to restriction of the present utility model.
Embodiment 1:
With reference to Fig. 1, a kind of shadow Spy hole of anti-theft door, comprises object lens 1 and eyepiece 2, also comprises
Electronic-control dimming glass 3, described electronic-control dimming glass 3 is arranged on the one end near eyepiece 2, and described electronic-control dimming glass 3 is connected with drive circuit 4 by switch;
LED 5, described LED 5 is connected with random signal generator 6, and described LED 5 is arranged on the periphery of electronic-control dimming glass 3.
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.
Described LED 5 is arranged near indoor one end.
When electronic-control dimming glass 3 does not power up, be in opaque light tight state; When the user of indoor needs from situation the eyepiece end observation ward of opal, the power supply connecting drive circuit 4 is only needed to be energized to electronic-control dimming glass 3, electronic-control dimming glass 3 becomes state that is transparent, printing opacity immediately, observe complete power-off, electronic-control dimming glass 3 recovers again opaque, lighttight state; In addition, the electronic-control dimming glass 3 when the light that the LED of irregular random light emission sends makes opaque presents the change of irregular light and shade, simulates the shadow change projected when indoor television set or people walk about on electronic-control dimming glass.
Embodiment 2:
With reference to Fig. 2, a kind of shadow Spy hole of anti-theft door, electronic-control dimming glass 3 is arranged between object lens 1 and eyepiece 2, and all the other are with embodiment 1.
