Description
Technical field
This utility model belongs to Household access control system field, particularly relates to a kind of domestic scalable visual field Anti-theft door mirror.
Background technology
Along with the development of society, the safe antitheft consciousness of people gradually strengthens, and the use of antitheft door has spread to each family
Each family, and on antitheft door, the most all can use peephole.Current peephole is due to the limitation of its optical texture, and field range is relatively
Little, it is impossible to see truth outdoors clearly, and utilize light path principle of reversibility, thief can see situation within doors from room clearly, profit
Door lock is opened, it is achieved theft with reserved peephole hole.So continuing a kind of to be realized antitheft door mirror by peephole.
Summary of the invention
This utility model example technical problem to be solved is, it is provided that a kind of good visual effect, low cost, structure letter
Single, safe and reliable peephole.
A kind of scalable visual field Anti-theft door mirror, it is characterised in that: include overall package box (1), described overall package box (1)
Internal one side threaded sleeve type lens barrel (3) of left end, described one side threaded sleeve type lens barrel (3) left part is provided with concavees lens (5), institute
Stating one side threaded sleeve type lens barrel (3) and be arranged above threaded drag strut (2), described concavees lens (5) left part is provided with double straight
Angle mirror cylinder (4), is provided with one side threaded sleeve type lens barrel baffle plate (11) outside described pair of right angle lens barrel (4) left end, described double straight
Angle mirror cylinder (4) left part is provided with a convex lens (6), and described convex lens (6) right part is provided with a reflecting mirror (7), institute
Stating reflecting mirror (7) bottom and be provided with No. two reflecting mirrors (8), described No. two reflecting mirror (8) right parts are provided with No. two convex lenss
(9), described No. two convex lens right parts are provided with No. three convex lenss (10), and described No. three convex lens (10) right parts are provided with looks around mouth
(12).
Further, pipe screw thread, and described one side threaded sleeve type mirror it are provided with outside described one side threaded sleeve type lens barrel
Cylinder diameter is more than right-hand member double right angles lens barrel left end diameter.
Further, described pair of right angle lens barrel is Z-shape.
Further, described reflecting mirror and horizontal line angle are 45 °-60 °.
Further, the diameter of described No. two convex lenss and No. three convex lenss is less than the internal diameter looking around mouth.
This utility model simple in construction that has the technical effect that of the present utility model, reasonable in design, easy for installation, cost is relatively
Low, one side threaded sleeve type lens barrel, double right angles lens barrel and threaded catch bar use stainless steel material, strengthen overall rigidity and
Attractive in appearance.Can realize after installation regulating the visual field, antitheft function, thus protect family's property and privacy.
Accompanying drawing explanation
Fig. 1 is this utility model structure chart；
Detailed description of the invention
The detailed description of the invention of utility model is further illustrated below in conjunction with Figure of description
As it can be seen, a kind of scalable visual field Anti-theft door mirror, it is characterised in that: include overall package box (1), described entirety
Internal one side threaded sleeve type lens barrel (3) of enclosure (1) left end, described one side threaded sleeve type lens barrel (3) left part is provided with recessed
Lens (5), described one side threaded sleeve type lens barrel (3) is arranged above threaded drag strut (2), described concavees lens (5) left part
Double right angle lens barrel (4) is installed, outside described pair of right angle lens barrel (4) left end, one side threaded sleeve type lens barrel baffle plate is installed
(11), described pair of right angle lens barrel (4) left part is provided with a convex lens (6), and described convex lens (6) right part is provided with No. one
Reflecting mirror (7), described reflecting mirror (7) bottom is provided with No. two reflecting mirrors (8), and described No. two reflecting mirror (8) right parts are installed
There are No. two convex lenss (9), described No. two convex lens (9) right parts that No. three convex lenss (10), described No. three convex lenss (10) are installed
Right part is provided with looks around mouth (12).
Described one side threaded sleeve type lens barrel (3) outside is provided with pipe screw thread, and described one side threaded sleeve type lens barrel 3 diameter
More than right-hand member double right angles lens barrel (4) left end diameter.Described pair of right angle lens barrel (4) is Z-shape, and described pair of right angle lens barrel (4) left part
Outside is provided with one side threaded sleeve type lens barrel baffle plate (11).Described reflecting mirror and horizontal line angle are 45 °-60 °.Described biconvex
The diameter of lens is less than the internal diameter looking around mouth.
During use, peephole is mounted on a door, scene outdoors pass sequentially through concavees lens (5), convex lens (6), one
Number reflecting mirror (7), No. two reflecting mirrors (8), No. two convex lenss (9), No. three convex lenss (10) and look around mouth (12) and arrive human eye, room
Interior observer can be observed the scene of outside, but when the people outside room observes within doors, because light cannot pass to recessed from reflecting mirror (7)
Lens (5), so situation within doors cannot be observed.
In sum, this utility model simple in construction that has the technical effect that of the present utility model, reasonable in design, installation side
Just, cost is relatively low, and one side threaded sleeve type lens barrel, double right angles lens barrel and threaded catch bar use stainless steel material, strengthen whole
The rigidity of body and attractive in appearance.Can realize after installation regulating the visual field, antitheft function, thus protect family's property and privacy.
