Description
Technical field
This practical Household access control system field, particularly relates to a kind of family expenses counnter attack and peeps peephole.
Background technology
Peephole popular name is called opal, due to the light that light to be sent by the appearance very similar Persian cat eyes seeing after its refraction it glisten a long way off evening, is opal so call to its.Current peephole is due to the limitation of the optical system of " opal " device, make angle of visibility less, the visual field is narrower, often can not see the truth of outdoor depth clearly, and, due to light path principle of reversibility or use " anti-opal ", make visitor can see situation in room from one end the room of " opal ", make thief carry out from reserved peephole hole in spy on the chance finding theft, simultaneously also from reserved peephole hole, row opening operation can be locked into by opposite house, realize the object of final theft.So be badly in need of a kind of door mirror that peephole can be made can to realize one way vision.
Utility model content
The utility model embodiment technical problem to be solved is, provides that a kind of good visual effect, cost are low, installation is simple, can realize the peephole of one way vision.
Peephole is peeped in a kind of family expenses counnter attack, and comprise straight lens barrel, described straight lens barrel left part is provided with concave-convex lens, and concave-convex lens makes people outdoors or thing imaging within it; Described straight lens barrel right part is provided with curved lens barrel by screw thread, and described curved lens barrel makes light path turn, thus reaches the object of one way vision; Described curved lens barrel circular arc place is provided with concavees lens, and the area that concavees lens accept light is comparatively large, and the picture that concave-convex lens can be made to be formed is completely reflected; Described curved lens barrel right angle is provided with level crossing, and described level crossing can make personage outdoors be presented on wherein, so that the people in door observes; Be provided with on the right side of described curved lens barrel and look around mouth, eyes are placed in and look around mouth place and observable by people; Described looking around in mouth is provided with biconvex lens, and described biconvex lens can make the picture in level crossing amplify, thus makes people be easier to observe.
Further, described straight lens barrel one end is provided with gas thread, and described straight lens barrel right-hand member external diameter is greater than left end and middle part external diameter, and described straight lens barrel material is stainless steel.
Further, described curved lens barrel is L-shaped, and described curved lens barrel left end is provided with external screw thread, and described curved lens barrel material is stainless steel.
Further, described concavees lens and the level crossing back side are coated with beam splitter layer; Described level crossing and horizon angle are 45 ° ~ 55 °.
Further, the external diameter of described biconvex lens is less than the internal diameter looking around mouth.
Technique effect of the present utility model shows: the utility model structure is simple, cost is lower, reasonable in design, easy for installation; the one way vision of peephole can be realized; straight lens barrel and curved lens barrel material all adopt stainless steel; enhance rigidity and the aesthetic property of peephole entirety; after installation, not easily from dismantling outdoors, effectively prevent the pilferage of thief; thus privacy and the safety of household can be protected, for people provide guard space that is good, secret.

In figure: 1, straight lens barrel, 2, concave-convex lens, 3, curved lens barrel, 4, concavees lens, 5, level crossing, 6, look around mouth, 7, biconvex lens.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 2, peephole is peeped in a kind of family expenses counnter attack, comprises straight lens barrel 1, and described straight lens barrel 1 left part is provided with concave-convex lens 2, and concave-convex lens 2 makes people outdoors or thing imaging within it; Described straight lens barrel 1 right part is provided with curved lens barrel 3 by screw thread, and described curved lens barrel 3 makes light path turn, thus reaches the object of one way vision; Described curved lens barrel 3 circular arc place is provided with concavees lens 4, and the area that concavees lens 4 accept light is comparatively large, and the picture that concave-convex lens 2 can be made to be formed is completely reflected; Described curved lens barrel 3 right angle is provided with level crossing 5, and described level crossing 5 can make personage outdoors be presented on wherein, so that the people in door observes; Be provided with on the right side of described curved lens barrel 3 and look around mouth 6, eyes are placed in and look around mouth 6 place and observable by people; Described looking around in mouth 6 is provided with biconvex lens 7, and described biconvex lens 7 can make the picture in level crossing 5 amplify, thus makes people be easier to observe.
Described straight lens barrel 1 one end is provided with gas thread, and described straight lens barrel 1 right-hand member external diameter is greater than left end and middle part external diameter, and described straight lens barrel 1 material is stainless steel.Described curved lens barrel 3 is L-shaped, and described curved lens barrel 3 left end is provided with external screw thread, and described curved lens barrel 3 material is stainless steel.Described concavees lens 4 and level crossing 5 back side are coated with beam splitter layer.Described level crossing 5 is 45 ° ~ 55 ° with horizon angle.The external diameter of described biconvex lens 7 is less than the internal diameter looking around mouth.
During use, indoor peephole is arranged on door, hold screwing of door of peephole insertion in the air and can complete installation, people are by looking around mouth 6 to observing outdoors, and scene is outdoors successively by concave-convex lens 2, concavees lens 4, level crossing 5 and biconvex lens 7, finally imaging in the eye retina of observer, observer can see the scene of outside, but when people from when observing outdoors in door, light path cannot reach concavees lens 4 from level crossing 5, so indoor scene cannot be observed.
In sum; the utility model structure is simple, cost is lower, reasonable in design, easy for installation; the one way vision of peephole can be realized; straight lens barrel 1 and curved lens barrel 3 material all adopt stainless steel, enhance rigidity and the aesthetic property of peephole entirety, after installation; not easily from dismantling outdoors; effectively prevent the pilferage of thief, thus privacy and the safety of household can be protected, for people provide guard space that is good, secret.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
