Abstract
The utility model discloses a back focusing structure for a CCD (charge coupled device) camera and a CMOS (complementary metal oxide semiconductor) camera. The back focusing structure is characterized in that an optical lens is arranged at the front end surface of a casing, a sensor assembly and the optical lens are positioned coaxially, the sensor assembly is arranged in the casing, the sensor assembly can move back and forth in the axial direction under the action of an axial driving mechanism, and an operation piece which is provided with an axial driving piece is positioned at the back end part of the casing. The back focusing structure has the advantage that on the premise of not changing the original front focusing structure of the camera, the back focusing function is additionally realized, and the front focusing function and the back focusing function are mutually complemented, so the accurate focusing under all engineering environments can be realized.
Description
Technical field
The utility model relates to the camera structure that adopts CCD, CMOS, imageing sensor such as infrared to constitute, the video camera focusing structure of more specifically saying so.
Background technology
At present, CCD, cmos camera and thermal infrared imager are widely used in security protection, industry, scientific research, education, family, amusement etc., and especially at safety-security area, application quantity rose in recent years, and the installation in general medium-sized city all reaches more than the hundreds of thousands platform.Video camera is installed and used in the process, and picture quality depends on installs the adjusting that focuses on.Focusing improperly will make image blurring unclear, greatly impact effect.All video cameras all can only be regulated at front end and focus in the prior art, connect signal wire and power lead in the rear end.But for the video camera that is installed in the protective housing, it is very inconvenient to operate the focusing structure that is positioned at front end, also is difficult to realize accurate adjusting, is difficult to carry out real-time regulated especially under the state when work; Also there is same problem in occasions such as education, industry, scientific researches.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of CCD, cmos camera back focusing structure are provided, with itself and the two complementation of existing front end focusing function that keeps, realizing the accurate focusing under the various engineering-environments.
The utility model adopts following technical scheme for the technical solution problem:
The characteristics of a kind of CCD of the utility model, cmos camera back focusing structure are: optical lens is arranged on the front end face of housing, the sensor module that is on the coaxial position with described optical lens is installed in the housing, described sensor module can move forward and backward under the effect of axial actuating mechanism vertically, and the controls that described axial actuator is set is in the rearward end of housing.
The characteristics of the utility model CCD, cmos camera back focusing structure also are:
Described axial actuating mechanism is the screw-nut structure that is made of screw rod and nut, described screw rod runs through the rearward end of described housing, be butted on the back of sensor module with the front end face of described screw rod, and can be with the reach that moves axially the described sensor module of pushing tow of screw rod; Described nut is fixedly installed on the rearward end of described housing, one end of extension spring is connected with described sensor module, the other end is connected with described nut, restoring force with described extension spring makes the front end face of described screw rod remain on the back that is butted on described sensor module, and described controls is the knob that is connected spiro rod rear end and is in outside.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model does not change the original front end focusing structure of video camera, increases focusing function in rear end is set, and the two complementation can provide the accurate focusing under the various engineering-environments.
2, simple in structure, the reliable in function of the utility model.
