Specific embodiment
Embodiment 1
As shown in Figure 1, intelligence lens adjustment device provided in this embodiment includes master controller, remote control terminal and camera
Camera lens, remote control terminal is transmitted by optical fiber to be connected with master controller, using fiber optic communication so that the place of working of remote control terminal
Point is unrestricted, and command range can be in the range of 300 meters.Fixed-focus camera camera lens lens barrel 2 and focusing in the present embodiment
The structure of ring, aperture ring 2 and focusing ring and the connection relation between camera lens are roughly the same, simply aperture ring 2 and focusing ring
Diameter and position on camera lens it is different, Fig. 2 and Fig. 3 show 2 mounting structure schematic diagram of aperture ring, focusing ring
Mounting structure schematic diagram is similar.
As shown in Figures 2 and 3, mounting bracket 1 is fixed on the camera lens, mounting bracket 1 is equipped with circular slot, circular
Bearing 3 is installed, aperture ring 2 is circular ring shape housing, and the inner walls of aperture ring 2 cooperate with the inner ring of bearing 3 in slot
And it is rotatably coupled with camera lens.The circumference of madial wall is equipped with external toothing 21 in the housing cavity of aperture ring 2, positioned at light
Micromachine 7 is fixed on bearing 3 in the housing cavity of ring 2, micromachine 7 uses micro-step motor, micromachine 7
