Summary of the invention

Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides and the object of this invention is to provide a kind of bending opal, for solving existing opal easily by technical problem that burglar destroys.

Technical scheme: for achieving the above object, the technical solution used in the present invention is:

A kind of bending opal, comprise straight tube and Z-shaped bend pipe, what be provided with concavees lens and convex lens in described straight tube is combined to form image one-way transmission path, one of described Z-shaped bend pipe is arranged at the straight tube open at one end of next-door neighbour's convex lens, two bending parts in described Z-shaped bend pipe are provided with a speculum and form periscope structure, and the other end of described Z-shaped bend pipe is peep hole.

The present invention by connecting Z-shaped bend pipe after straight opal lens tube, by two speculums will outdoors image transmission in room, can prevent outdoors personnel by destroying glass lens by straight tube hole unlatching burglar-proof door or injury room personnel.Above-mentioned bending opal may be used for security door or the left front of naked eye, also may be used for the security door that is connected with CCD imaging system or left front.

Further, in the present invention, described Z-shaped bend pipe comprises middle supervisor and is positioned at the bending tube at supervisor two, and the axis of described bending tube is mutually vertical with the axis of supervisor, and the minute surface of described speculum and the axis angle of bending tube are 30 ° ~ 60 °.

Further, in the present invention, the minute surface of described speculum and the axis angle of bending tube are 45 °.

Beneficial effect:

The problem of current Spy hole of anti-theft door is that metal tube internal diameter size is large, short and point-blank, thus is easy to destroy.The application proposes bending opal first for this reason, namely connects a zigzag bend pipe at original straight tube containing two lens and formed periscope structure by built-in two tilted-putted speculums to be observed to the peep hole of zigzag bend pipe by the image transmission outdoors of the security door of lens combination acquisition in straight tube;

The bending opal of the application can not only ensure that personnel can observe situation outdoors after room door, and attempt to pull the situation of door handle effectively to avoid by drag-line for after destruction lens, because its drag-line of straight opal to be carried out through straight tube can bend once overlapping, pulling process, but bend opal system for Z-type and then need bending three times, it is very difficult that it manipulates door handle outdoors;

In addition the zigzag bend pipe selecting high-strength material to make bending opal therefore also can avoid personnel outdoors by opal hole with personnel in gun injury room may, so the bending opal system of the application can more effectively be protected house to exempt to commit theft, be plundered and personal injury.
