Abstract
The utility model discloses a back focal plane type camera. The back focal plane type camera comprises a housing portion and an inner accurately-assembled portion. The housing portion is mainly composed of a front end cover, a middle housing, a rear end cover, a tail board baffle and a baseboard. A pick-up lens is installed on the front end cover, the front end and the rear end of the middle housing are connected with the front end cover and the rear end cover respectively, the lower end of the middle housing is connected with the baseboard, and the tail board baffle is fixed on the rear end cover. The inner accurately-assembled portion is installed inside the housing portion. The accurately-assembled portion is mainly composed of a CCD image sensor, a motor, a guide bar seat and a sliding plate. The CCD image sensor is fixed on a fixed mount which is installed on the sliding plate, the lower end of the motor is installed with a motor shaft, the motor is installed on the sliding plate, the sliding plate is connected with the guide bar seat, and the guide bar seat is fixed on the base. According to the utility model, the shortage of a conventional camera is solved by changing the relative position of the CCD image sensor and the lens of a camera so to as suit the imaging of lights having different wavelengths, so the back focal length of the camera product can be adjusted according to the needs of use, so that the practicability of the camera is improved.
Description
Technical field
The utility model relates to the security product field, is specifically related to a kind of plane video camera of regulating imageing sensor and camera lens relative position device with intelligence.
Background technology
Nowadays the video camera product that uses of safety-security area all is the fixing product of back focal length, and back focal length in use is unalterable, can not be according to the back focal length of corresponding this video camera of change of usefulness needs; Development along with security and guard technology, be used for the video camera of security protection towards using continuously round the clock future development, the video camera General Requirements of working at night adopts the infrared light supply floor light, because infrared light and traditional visible wavelength difference are very large, the back focal length of video camera is regulated and is often caused daytime and work at night and can't take into account, and can not satisfy the requirement of image definition.
The utility model content
For the problems referred to above, the utility model aim to provide a kind of can according to use the corresponding change camera back focus of needs apart from and guarantee the back focal plane video camera of image definition.
For realizing this technical purpose, scheme of the present utility model is: a kind of back focal plane video camera, comprise housing parts and inner hard-cover part, wherein: housing parts mainly is comprised of front end housing, mesochite, rear end cap, tailgate catch and base plate, pick-up lens is installed on the described front end housing, the front and back end of described mesochite is connected with described front end housing, described rear end cap respectively, and the lower end of described mesochite is connected with described base plate, and described tailgate catch is fixed on the described rear end cap; Described inner hard-cover part is installed in the inside of described housing parts; Described hard-cover part mainly contains ccd image sensor, motor, guide rod seat and slide plate and forms, described ccd image sensor is fixed on the fixed mount that is installed in described slide plate, described motor lower end is equipped with motor shaft, described motor is installed on the described slide plate, described slide plate is connected with described guide rod seat, and described guide rod seat then is fixed on the said base.
As preferably, described motor shaft is connected with cam, and described cam is installed on the cam holder.
As preferably, be equiped with ball bearing between described cam and the described slide plate.
As preferably, fixedly mount a pilot pin at described base plate, the upper end of described pilot pin embeds in the curved groove of described cam.
The utility model has solved the deficiency of traditional cameras with the way that is fit to the different wave length image formation by rays by the relative position that changes video camera ccd image sensor and camera lens.When using by day, ccd image sensor is adjusted on the back focal plane of visual light imaging of camera lens, made video camera obtain clearly coloured image; The chien shih time spent very night, infrared floor light is opened, and at this moment we adjust to the video camera ccd sensor on the back focal plane of near infrared imaging, make video camera obtain clearly coloured image; Thereby make the back focal length of video camera product according to using needs to regulate, strengthened the Practical Performance of video camera.

Fig. 2 is structural front view of the present utility model;
Fig. 3 is structural perspective of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, a kind of back focal plane video camera of the utility model specific embodiment, comprise housing parts and inner hard-cover part, ccd image sensor adjusting device of the present utility model is installed in the seal casinghousing, this housing is mainly by front end housing 6, mesochite 13, rear end cap 14, tailgate catch 15 and base plate 9 form, pick-up lens 1 is installed on the described front end housing 6, the front and back end of described mesochite 13 is respectively with described front end housing 6, described rear end cap 14 is connected, the lower end of described mesochite 13 is connected with described base plate 9, and described tailgate catch 15 is fixed on the described rear end cap 14; Ccd image sensor 2 is fixed on the fixed mount 3, described fixed mount 3 is installed on the slide plate 4, described slide plate 4 is connected with guide rod seat 7, described guide rod seat 7 is fixed on the base plate 9, the lower end is set with the motor 5 of motor shaft 10 at slide plate 4, described motor shaft 19 joins with cam 11, described cam 11 is installed in the cam holder 8, again at base plate 9 fixed installations one pilot pin 12, pilot pin 12 upper ends embed in the curved groove of cam 11, between cam 11 and the slide plate 4 ball bearing 16 is installed, when motor 5 rotates, by the rotation of motor shaft 10 with moving cam 11, owing to fixedly mounted pilot pin 11 at base plate 9, cam 11 promotes slide plate 4 and motor 5 fixed thereon under the driving of reaction force, and the ccd image sensor 2 that is installed on slide plate 4 fixed heads 3 is just done and seesawed along with slide plate 4, thereby realize changing the relative position of ccd image sensor 2 and pick-up lens 1, and then change back focal length.
The utility model has solved the deficiency of traditional cameras with the way that is fit to the different wave length image formation by rays by the relative position that changes video camera ccd image sensor and camera lens.When using by day, ccd image sensor is adjusted on the back focal plane of visual light imaging of camera lens, made video camera obtain clearly coloured image; The chien shih time spent very night, infrared floor light is opened, and at this moment we adjust to the video camera ccd sensor on the back focal plane of near infrared imaging, make video camera obtain clearly coloured image; Thereby make the back focal length of video camera product according to using needs to regulate, strengthened the Practical Performance of video camera.
The above; it only is preferred embodiment of the present utility model; not in order to limiting the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, all should be included within the protection range of technical solutions of the utility model.
