Description
Technical field
The utility model is related to a kind of telephoto lenses with visual field handoff functionality, belong to optical observation equipment field.
Background technology
In safety-security area, video monitoring has become the important component of safety and protection system.In recent years, with calculating
The rapid development of machine, network and image procossing, transmission technology, there has also been tremendous developments for Video Supervision Technique.
For current demand, long-distance large-range monitoring is still hot issue, but in order to realize remote monitor,
Mode relatively conventional at present is to rely solely on lens optical zoom；This mode not only can cause cost higher, and need
The very long design cycle.
Therefore, in order to simply and effectively realize remote monitor, a kind of telephoto lens with visual field handoff functionality is designed,
It is those skilled in the art's urgent problem to be solved.
Invention content
To solve the problems, such as that telephoto lens used in monitor camera in the prior art is of high cost, design cycle length, this practicality
A kind of simple structure of novel offer, the telephoto lens with visual field handoff functionality at low cost, using following technical proposals：
A kind of telephoto lens with visual field handoff functionality, which is characterized in that including：Telescope, painted switchable lenticular module；
Wherein, painted switchable lenticular module includes at least one increment microscope group, the connection for connecting and switching increment microscope group
Component, the driving part for being drivingly connected component；
The connecting elements includes being connected to shaft outside painted switchable lenticular module and by increment microscope group circumference around the shaft
The fixing piece of distribution；
The driving part includes stepper motor, controls the controller of stepper motor；The stepper motor and the shaft
It is connected with transmission parts.
Preferably, the increment microscope group is 2, respectively 1.5 times, 2 times distance microscope groups.
Or it is preferred, the connecting elements further includes a shading that light leakage is prevented when increment microscope group is moved away from light path
Circle.
Or it is preferred, the transmission parts are gear pair, belt transmission pair or coaxial connector.
The utility model has the following advantages that：
（1）Compared with the CCTV camera lenses of current monitoring, the price and weight of the utility model will be than CCTV camera lenses
It is much lower.
（2）Large aperture telescope is easier to realize than heavy caliber CCTV camera lenses；Under same illumination condition, especially carry out
When remote monitor, select large aperture telescope that can so that light-inletting quantity is more, to being imaged advantageously.
（3）Between telescope and video camera increase painted switchable lenticular module, increase telescope focal length improve monitoring away from
From under the premise of, overall volume and weight change are little, and the shield and holder for whole system will not form more pressure.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is connecting elements structural schematic diagram in the utility model embodiment；
Wherein：1. video camera, 2. painted switchable lenticular modules, 3. stepper motors, 4. controllers, 5. telescopes, 6. shafts, 7.
Increment microscope group, 8. darkening rings.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of telephoto lens with visual field handoff functionality, including：
Including：Telescope 5, painted switchable lenticular module 2, lens barrel；
Telescope 5 is arranged in lens barrel front end, and painted switchable lenticular module 2 is arranged in lens barrel stage casing；Lens barrel rear end with without imaging lens
The mouth connection of finding a view of the video camera 1 of head, video camera 1 is gun shaped video camera.
Wherein, in the present embodiment, painted switchable lenticular module 2 includes 2 increment microscope groups 7, for connecting and switching teleconverter
Connecting elements, the driving part for being drivingly connected component of group；2 increment microscope groups 7 are respectively 1.5 times, 2 times distance mirrors
Group.
The connecting elements as shown in Fig. 2, including being connected to shaft 6 outside painted switchable lenticular module, by increment microscope group 7
The fixing piece of 6 circle distributions and the darkening ring 8 of light leakage is prevented when increment microscope group is moved away from light path around the shaft；The shaft 6
It is rotatablely arranged at outside painted switchable lenticular module by 2 parts of bearings；The darkening ring 8 and 2 increment microscope groups 7 are uniform
Distribution, outer diameter is identical and is more than or equal to the lens barrel internal diameter.When work, increment microscope group 7 or darkening ring 8 and telescope 5, video camera
A 1 mouthful central coaxial of finding a view.
The driving part includes stepper motor 3, controls the controller 4 of stepper motor；The controller 4 includes PLC, control
System switch；The stepper motor is connect with the shaft with coaxial connector.Control switch selects line traffic control pulse in the present embodiment
Switch, is electrically connected with PLC, and pulse signal can be sent to PLC in the case where controller controls；PLC internal preset programs receive pulse and open
It closes a pulse signal and sends control instruction, stepper motor 3 is made sequentially to rotate fixed angle, be rotation in the present embodiment
120°。
Selected 1.5 times, 2 times distance microscope groups 7 in the present embodiment, existing market have more mature product for choosing
With；The position of painted switchable lenticular module 2 is arranged according to the specification demands of increment microscope group 7.
When for video monitoring, painted switchable lenticular module 2 is mainly used for when monitoring distance farther out, screen shared by target
Ratio it is smaller be difficult when telling the details of target, using driving part switching increment microscope group 7, increment microscope group 7 can will hope
The focal length amplification of remote mirror so that shared ratio increases target in whole screen, is more easy to distinguish the minutia of target.When not
When needing amplification again, it is coaxial with lens barrel that controllable connecting elements switches to darkening ring 8, participates in light path without increment microscope group 7 at this time,
By telescope 5 and 1 cooperating of video camera.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use this practicality new
Type.A variety of modifications of embodiment will be apparent to those skilled in the art, it is as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present utility model, not given
