The utility model is arranged in a mirror barrel; wherein two ports of the mirror barrel are provided with a convex and a concave mirror; and the port face of the mirror barrel door is provided with a light protective cone which is connected with the mirror barrel wall through a rotor axis and rotates on the port face of the mirror barrel by winding around the rotor axis; the rotor axis is sleeved with a torsion spring, wherein two arms of the torsion spring are respectively blocked on the mirror barrel and the light protective cone; and the light protective cone can be automatically closed when not under the spring action and opened by an inner door to observe the outside when in need, thereby preventing outside peep.
Description
Affiliated technical field
The utility model is the peephole on a kind of door.
Background technology
At present, people have generally installed peephole in order to see the scene outside the door in door on door.Peephole is made up of lens, combination by convex lens, concavees lens reflects light, makes the observer can see outdoors scene on a large scale with little visual angle in door, people outdoors then can't see the scene in the door, and this has played certain effect at secure context at home.But,,, work the mischief to home safety being added in the scene that just can peep on the peephole in the door with convex lens outdoors along with the commit a crime raising of level of offender.
Summary of the invention
The utility model purpose be to provide a kind of in can't seeing door outdoors the anti-peephole of peeping of scene.
Scheme of the present utility model is: in lens barrel, convex lens, concavees lens are separately positioned in two ports of lens barrel, on the end face in the lens barrel door light shield is set, light shield is connected by rotating shaft with the lens barrel wall, can on the end face of this rotating shaft, rotate at lens barrel, sheathed torsion spring in the rotating shaft, two arms of torsion spring are stuck on lens barrel and the light shield.Light shield is closed by the elastic force effect automatically in time spent not, prevent to peep in door outdoors, then can open light shield in use in the door and outwards observe.
The utility model has the advantages that by on the end face in the lens barrel door light shield being set, this light shield can only outwards be watched when needed by opening in the door, has prevented to peep outdoors in door.
