Abstract
The utility model relates to a safe one-way transparent cat eye which comprises a cat eye body branch pipe, an internal convex lens and an external convex lens, wherein the internal convex lens and the external convex lens are arranged inside the cat eye body branch pipe, a plano lens is arranged on the port of the cat eye body branch pipe close to the external convex lens, and a one-way light-transmitting mirror is arranged on the port of the cat eye body branch pipe close to the internal convex lens; light can be transmitted to the interior of the cat eye body branch pipe from the outside, and transmitted in a room through the external convex lens, the internal convex lens and the one-way light-transmitting mirror, thus enabling people in the room to be capable of seeing the visual image of the outside and people outside the room to be incapable of seeing the visual image in the room, and further realizing the personal safety and property safety and privacy of a user in the room; and furthermore, the one-way light-transmitting mirror is arranged inside a door body, and is not easily damaged by the outside people, thus playing a good protection role in the one-way light-transmitting mirror, and being beneficial to use and protection in the safety aspect.
Description
Technical field
The utility model relates to civilian security fields, is specifically related to a kind of opal peephole, the unidirectional printing opacity opal of particularly a kind of safety.
Background technology
" reflective mirror " arranged in the eyeball of opal, have layer film in amphiblestroid back reflection ray, Here it is, and its eyes seem so bright reason, the cone cell of cat have only green with blue two kinds.Opal is claimed peephole again, is a kind of compact optical instrument that is contained on the door of dwelling house family, is convenient to the resident and observes outdoor situation.
In the prior art, mostly the opal peephole that people use is two-way printing opacity opal, and the thief can be from observing light within doors outdoors, and can judge whether the people is arranged within doors according to light, and then implement larceny; Traditional opal is unfavorable for protecting personal safety and proprietary safety, and is unfavorable for protecting people's privacy.
Therefore, produce a kind of simple in structurely, safety factor is high, and it is anti-tampering guard against theft, is beneficial to the unidirectional printing opacity opal of safety of protecting user's privacy, has vast market prospect.
Summary of the invention
To the deficiency of prior art, the utility model provide a kind of simple in structure, safety factor is high, antitheft is anti-tampering, be beneficial to the unidirectional printing opacity opal of safety of protection user privacy.
The technical scheme of the utility model is such realization: the unidirectional printing opacity opal of a kind of safety; Comprise opal body arm, be arranged on opal body arm inner interior convex lens and outer convex lens; Port near the opal body arm of evagination lens position is provided with goggles, is provided with unidirectional transmissive mirror near the port of the opal body arm of convex lens position.
The diameter of described outer convex lens is greater than the diameter of interior convex lens.
It is inner that described outer convex lens are installed in opal body arm through first bearing.
Convex lens are installed in opal body arm inside through second bearing in described.
The printing opacity direction of the described unidirectional transmissive mirror inside convex lens of outer convex lens of serving as reasons.
The utlity model has following good effect: this product structure is simple; Easy to operate; Comprise opal body arm, be arranged on opal body arm inner interior convex lens and outer convex lens; Port near the opal body arm of evagination lens position is provided with goggles, is provided with unidirectional transmissive mirror near the port of the opal body arm of convex lens position, and it is inner that light can penetrate into opal body arm from the external world; And penetrate within doors through outer convex lens, interior convex lens and unidirectional transmissive mirror; Can make people within doors see extraneous visual imaging, and the people outside the room can not see visual imaging within doors, thereby realize protecting user's personal safety, proprietary safety and privacy within doors; And unidirectional transmissive mirror is installed in the inside of a body, and extraneous personnel are not easy to destroy, and unidirectional transmissive mirror is played a very good protection, and help using and protecting of secure context.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The unidirectional printing opacity opal of a kind of safety; Comprise opal body arm 1, be arranged on opal body arm 1 inner interior convex lens 2 and outer convex lens 3; Port near the opal body arm 1 of outer convex lens 3 positions is provided with goggles 6, is provided with unidirectional transmissive mirror 7 near the port of the opal body arm 1 of interior convex lens 2 positions.
The diameter of described outer convex lens 3 is greater than the diameter of interior convex lens 2.Described outer convex lens 3 are installed in opal body arm 1 inside through first bearing 4.Convex lens 2 are installed in opal body arm 1 inside through second bearing 8 in described.The printing opacity direction of the described unidirectional transmissive mirror 7 outer convex lens 3 inside convex lens 2 of serving as reasons.
In use; Light 5 outside the room can only enter into opal body arm 1 inside through goggles 6; And the outer convex lens 3 of process pass to unidirectional transmissive mirror 7 with interior convex lens 2 with light; And enter into user's sight line within doors through unidirectional transmissive mirror 7, and can let within doors the user observes the visual imaging outside the room, convenient and swift; Otherwise; When the people being arranged outside the room through being installed near the goggles 6 on the port of the opal body arm 1 of outer convex lens 3 positions when observing within doors; The outer convex lens 3 inside convex lens 2 because the printing opacity direction of unidirectional transmissive mirror 7 is served as reasons are so light within doors can not see through unidirectional transmissive mirror 7 back transfer; Promptly; Convex lens 2 and outer convex lens 3 in light within doors can not pass to through unidirectional transmissive mirror 7, whether so the people outside the room can not observe visual imaging within doors, can not judge has the people within doors.
Use the unidirectional printing opacity opal of the described safety of the utility model; Can make people within doors see extraneous visual imaging; And the people outside the room can not see visual imaging within doors; Give thief and lawless person with the fright effect, thereby realize protecting user's personal safety, proprietary safety and privacy within doors.
