Description
Technical field
The utility model relates to the video technique field, particularly relates to the manual focusing video camera.
Background technology
Existing small-sized image pickup head because volume is small and exquisite, in light weight, the power consumptive province, easy to install, gather the photo resolution height, be used widely in recent years, such as being applied to fields such as security protection, military affairs, traffic administration, public place supervision.
Consult Fig. 1, prior art is a kind of to be applied to monitor and to utilize the video camera of above-mentioned small-sized image pickup head to comprise camera lens.Described camera lens comprises front focus adjustment barrel 110 and rear focus adjustment barrel 120.Be integrated by adapter ring 130 sockets between described front focus adjustment barrel 110 and the rear focus adjustment barrel 120.Described front focus adjustment barrel 110 and rear focus adjustment barrel 120 outer surfaces radially are provided with respectively front burnt adjusting rod 111 and rear burnt adjusting rod 121, by rotate described front burnt adjusting rod 111 and rear burnt adjusting rod 121 at the camera lens circumferencial direction, can regulate respectively the focal length of front focus adjustment barrel 110 and rear focus adjustment barrel 120, to gather the picture of different distance.
For realizing still utilizing camera to monitor on-the-spot purpose under the insufficient light environment, be provided with infrared light board 140 in described front focus adjustment barrel 110 near camera lens front end one side, be used for towards scene emission infrared ray.The infrared view that reflects arrives the image acquisition element of camera lens rear end through camera lens.Described camera lens rear end generally also comprises the structure of camera base or fuselage 150 and so on, and described camera is fixed on buildings or locality by described base or fuselage 150, and fixing described image acquisition element afterwards can be stablized the collection site image.
Consult Fig. 2 and Fig. 3, realize waterproof and dustproof effect for making camera, prior art proposes the method for sheathed urceolus 230 outside described camera 210.For making compact conformation, the space designs lessly between described urceolus 230 and the described camera lens, and remove described preceding burnt adjuster bar and the burnt adjuster bar in back, and replace described preceding burnt adjuster bar and the effect of burnt adjuster bar afterwards with preceding adjusting gear 211 and back adjusting gear 212 in addition, and focus for being implemented in urceolus 230 back, adopted two radicles to be provided with the transmission shaft 213 of meshing gear.The meshing gear of described transmission shaft 213 1 ends and described preceding adjusting gear 211 and 212 engagements of back adjusting gear, the other end extends to the back of whole video camera and stretches out described urceolus 230 dorsal parts, and adopts card extender 214 to fix the position of described transmission shaft 213.Mainly utilize the mode of gear and gear engagement, and power transmission shaft 213 transmits regulating rotary power.At the described power transmission shaft 213 of the back of video camera turn, power transmission shaft drives described front adjusting gear 211 or rear adjusting gear 212 rotates during adjusting, and then drives front focus adjustment barrel and rear focus adjustment barrel rotation, realizes the function of focusing.
But, owing to need user's winding by hand to the back of video camera to remove the described transmission shaft 213 of turn when regulating, and the back of video camera often is a wall, is back to the user, less and the user in the operating space of this position is difficult to observe, and therefore causes operating difficulties; In addition, above-mentioned transmission shaft 213 is long, and the end is less, the difficult control of the feel of its adjusting and precision, and the precision of its cooperation is also had relatively high expectations, fit and complex process; Because need special card extender 214 to fix the position of transmission shaft 213, the part of cooperation is a lot, causes cost just high again; In addition, because corresponding two the outer point of adjustment of stretching out urceolus 230 of focusing part, the waterproof of video camera is also comparatively difficult.
