Abstract
The utility discloses a handheld screen-display day and night observation mirror. The observation mirror comprises a mirror body, an objective lens assembly disposed at the front end of the mirror body, an imaging assembly disposed inside the mirror body, wherein the rear end of the mirror body is provided with a display screen assembly and the display screen assembly is connected with the mirror body through a display connection plate and a press plate. According to the observation mirror, a low-light level black and white CCD and infrared additional lighting are adopted, and the observation mirror is more stable in performance and clearer in imaging than night vision devices which adopt vacuum imaging devices such as image enhancing devices; LCD direct display is adopted, and therefore observation is facilitated, and no fatigue is easily caused even in long-time use. The handheld screen-display day and night observation mirror is high in reliability and low in price, and has marketing promotion value.
Description
Technical field
The utility model relates to the photoelectric instrument field, is specifically related to a kind of hand-held screen and shows sight glass round the clock.
Background technology
What present domestic night or daytime, sight glass adopted is the imaging of image intensifier equal vacuum device.Target is imaged on the image intensifier cathode plane through object lens, and after image intensifier strengthened, the image that on display screen, becomes brightness to strengthen, this image need amplify through eyepiece to be observed.This series products need be close on the eyepiece with eyes and observe, the observation place relative fixed, and the brightness of image after eyepiece amplifies is very high; Eyes easy fatigue during long-time the observation; Such valuable product, and adopt the properties of product of generation glass tube unstable, and not fogging clear.
Summary of the invention
The utility model provides a kind of imaging clear, observes comfortablely, and long-time the use is difficult for producing tired, and the hand-held screen of stable performance shows the night vision sight glass.
The technical scheme of the utility model: a kind of hand-held screen shows sight glass round the clock, comprises the mirror body, the objective lens unit that mirror body front end is provided with, and the image-forming assembly of mirror body set inside, mirror body rear end is provided with display screen component, is connected with the mirror body through showing web joint, pressing plate.The image-forming assembly of the utility model adopts to be surveyed illumination and reach 0.001lx, and resolving power is the low-light (level) 1/3 of 480 lines, and " black-white CCD, display screen adopts 2.4 "～2.5 " LCD display; under night or daytime environmental baseline; at image-forming assembly CCD target surface, the CCD assembly is through the processing of circuit outputting video signal with target imaging for object lens, and this signal send display screen component; after assembly circuit drives, demonstrate target image by LCD.Rotate focusing handwheel and can drive the relative objective holder of objective lens and move forward and backward and accomplish focusing, it is clear that the target that can guarantee different distance in 2m～∞ scope all forms images
Connect through Connection Block between mirror body and the objective lens unit; Image-forming assembly is connected with Connection Block through the double-screw bolt of mirror body set inside; Double-screw bolt connects the low-voltage circuit plate through web joint.
Mirror body front end outside is provided with protecgulum, is provided with infrared LED, collector lens, supply socket in the protecgulum.When night ambient light illumination very low, when observing effect is bad, can open the infrared LED switch, light infrared floor light, under the effect of collector lens, night, illumination was improved, and can guarantee the observing effect of 30m with internal object.
Show on the web joint power switch, LED switch, low pressure alarming LED are set.When charged battery voltage was low, by lighting low pressure alarming LED after the detection of low-voltage circuit plate, this moment, the observer used charger, inserted in the supply socket and charged.
Objective lens unit is made up of objective holder, focusing handwheel, camera lens and guard shield.
The mirror body is made up of the right shank of left shank, and the battery cavities that rechargeable battery can be installed is set between the shank of the left and right sides.
Outside, mirror body rear end is provided with the bonnet of band cone.
The technique effect of the utility model: the utility model has adopted the low-light (level) black-white CCD, and infrared floor light is more clear than night vision device stable performance, the imaging of employing image intensifying device equal vacuum image device; LCD directly shows; The convenient observation, long-time use is difficult for producing tired, and reliability is high; Low price has market popularization value.
