Abstract
The utility model discloses a kind of curve cylinder focusing lens, the camera lens includes front lens mechanism, rear lens mechanism and curve cylinder, and front lens mechanism is movably connected in one end of curve cylinder, and rear lens mechanism is movably connected in the other end of curve cylinder；The different curved groove of multiple radians is provided with the outside of curve cylinder, preceding lens mechanism and rear lens mechanism is movably connected on curved groove.In the case where lens focus is constant, during the far and near different object of shooting, preceding lens mechanism and rear lens mechanism can move different distance in each different curved grooves, ensure the accurate focusing to photo-object, realize and become apparent from when digital camera gathers image.
Description
Technical field
The utility model belongs to camera technical field, more particularly to a kind of curve cylinder focusing lens.
Background technology
What the general principle of camera operation was just as：Optical image signal is changed into electric signal, in order to store
Or transmission.When we shoot an object, the light reflected on this object is collected by camera lens, it is focused on shooting
On the smooth surface of device, then light is changed into by picture pick-up device by electric energy, that is, obtained " vision signal ".Photosignal is very micro-
It is weak, it need to be amplified by pre-arcing road, then handled and adjusted by various circuits, the standard signal finally obtained can be with
It is sent on the recording mediums such as video recorder and records, or propagates or be sent on monitor by broadcasting system and show.
Camera lens is the important component of video camera, when existing common lens are taken pictures, by the way of rear thread is adjusted
Moving lens distance focusing, the effect of focusing can not be controlled accurately because of displacement, it is difficult to are formed scenery focusing, influenceed camera picture
The definition in face.
Utility model content
To solve the above problems, the purpose of this utility model is that providing one kind can accurately focus, when making collection image
The curve cylinder focusing lens become apparent from.
To achieve the above object, the technical solution of the utility model is as follows.
A kind of curve cylinder focusing lens, the camera lens include front lens mechanism, rear lens mechanism and curve cylinder, the front lens
Mechanism is movably connected in one end of curve cylinder, and rear lens mechanism is movably connected in the other end of curve cylinder；The curve cylinder
Outside is provided with the different curved groove of multiple radians, and the preceding lens mechanism and rear lens mechanism are movably connected in curved groove
On.
Further, the front lens mechanism includes barrel unit, focusing ring, spacer ring and aperture, the barrel unit connection
In the inner side of curve cylinder one end, the spacer ring and aperture are arranged in curve cylinder after assembling successively, and the focusing ring is flexibly connected
On the curved groove of curve cylinder side, and focusing ring is fixedly connected with spacer ring and barrel unit.
Further, the barrel unit includes preceding lens barrel and middle lens barrel, and the preceding lens barrel is connected to one end of middle lens barrel,
And the other end of middle lens barrel is connected to the inner side of curve cylinder one end and is connected to focusing ring and spacer ring.
Further, rear lens mechanism lens barrel, rear lens barrel lens set, pressure ring and C interface, the rear lens barrel,
Lens set, pressure ring and C interface by rear lens barrel are connected to aperture ring after assembling successively, and the aperture ring is movably connected in curve cylinder
On the curved groove of opposite side.
Further, the camera lens also includes identification rings, and the identification rings are clamped between focusing ring and aperture ring, and identification rings
Both ends be flexibly connected respectively with focusing ring and aperture ring.
Advantage of the present utility model is：Compared to prior art, curve cylinder focusing lens provided by the utility model, lead to
Cross and be provided with curve cylinder, preceding lens mechanism and rear lens mechanism, and the curved groove of a plurality of different radians is set on curve cylinder, it is preceding
Lens mechanism and rear lens mechanism are movably connected on curved groove, in the case where lens focus is constant, are shot far and near different
Object when, preceding lens mechanism and rear lens mechanism can ensure to clapping in each mobile different distance in different curved groove
According to the accurate focusing of object, realize and become apparent from when digital camera gathers image.
