Description
The utility model relates to a kind of safety theftproof device of being convenient to observe that is arranged on the door, the optical visible peephole of particularly a kind of similar " opal ".
At present, people have the people to install on door and are convenient to observe " opal " of sound outdoors for safe antitheft.But the radius-of-curvature of this " opal " is less, and inconvenience strengthens the bore (otherwise people outdoors can see indoor scene) of lens again, and therefore, messenger is outdoors observed in people's inconvenience, and being difficult for differentiating messenger is acquaintance or stranger, the security identification ability.In addition, the optical mirror slip of this " opal " is little, and structure is complicated, and general difficult processing is to guarantee image quality.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provide a kind of simple in structure, be convenient to observe, differentiate the high safe antitheft optical visible peephole of discrimination.
The purpose of this utility model is achieved in that it includes lens barrel 3 and lens.The outer end of lens barrel 3 is provided with convex-concave eyeglass 1 by preceding mirror lid 2, the front portion is provided with an optical prism group 4 in lens barrel 3, the middle part is provided with imaging len 5, and rearward end is provided with biconvex sight glass 4 by back trim ring 8, trim ring 6 during the periphery of lens barrel 3 is provided with by screw thread.
The above-mentioned said imaging len 5 that is arranged on middle part in the lens barrel 3, its quantity is two, front and back are arranged in order.
Advantage of the present utility model is simple in structure, appearance looks elegant, and fabrication and installation are convenient, and externally observing has bigger wide-angle (90 °～120 °), and bigger amplification (1～2 times) is arranged, and opposite house stranger's resolution discrimination height has improved the effect of safe antitheft.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the front elevation of the optical prism group 4 among Fig. 1.
Each structure shown in the drawings is exactly embodiment of the present utility model.Among the figure, 1 for being coated with the convex-concave eyeglass of coloured antireflective coating, seems a bright eyes from seeing outdoors, and novel and beautiful also has dustproof effect.2 are the fixing preceding Jing Gai of convex-concave eyeglass 1, after eyeglass is put into it, are fixed by being threaded into a trim ring 9, and internal thread and lens barrel 3 external threads by trim ring 9 join again.3 for being provided with the lens barrel of each eyeglass in it, there is screw thread the outer ring, and back volume is bigger than anterior.4 is the optical prism group of being made up of two prismatic glasseses, and every is semicircle isosceles shapes, and isogonism 〉=45 °.5 is the imaging len of being made up of two eyeglasses.6 for be arranged on the middle trim ring of lens barrel periphery by screw thread, during installation lens barrel 3 is inserted in the aperture of door, is tightened on door by trim ring.7 is the biconvex sight glass.8 are the fixing back trim ring of biconvex sight glass, join by screw thread and lens barrel rear end.9 is the trim ring of fixing len 1.10 is the trim ring of fixed prism 4 and lens 5.11 for fixing the trim ring of two lens 5.The utility model is except that each eyeglass, and whole external structure can adopt metal or plastics die cast all can.The metal surface can be coated with imitative gold increases aesthetic, and working of plastics is decorated with the plastic-blasting color.Each eyeglass adopts optics flint glass commonly used to make.Optical prism 4 in the utility model has just as accepting the effect of light with large tracts of land, by behind the optical prism inverted image through two lens 5, people and thing outdoors can be imaged on the biconvex sight glass 7.The 1st of biconvex sight glass is the polishing sphere, makes outdoors people and thing amplify 1～2 times, increases brightness, and the 2nd is the convex surface frosting, guarantees that edge and center imaging are evenly clear, and the people outside also making can't see the scenery in the door.Indoor people seems a minitelevision image like the visitor outdoors of Direct observation from the screen, particularly makes things convenient for not so good old man of eyesight or child to observe identification in any position from door.
