Description
Affiliated field:
The utility model relates to a kind of computer camera.
Background technology:
At present, camera is installed all on many computers, so that transmitted image and mutual interchange in real time on the net, at ordinary times can also photographic images and utilize computing machine to handle, but it has only a short-focus lens, and the distance of shooting is limited, can not take the observation distant objects.For improving its function, a kind of computer camera with telephoto lens just appears, but this long-focus camera still has following defective: 1) Focusing mechanism of this camera utilizes the focus control compression spring to promote moving forward and backward of lens barrel the inside camera lens, focusing speed is slow and unstable, accuracy is low, and the image definition that shooting is come out is not high; 2) photoelectric sensor of this camera can not move, be that reflective mirror is sent on the photoelectric sensor mainly by the light path switching mechanism, because the light path switching mechanism is positioned at the photoelectric sensor top, so when regulating the light path switching mechanism, dust on the switching mechanism (reflective mirror) falls into the photoelectric sensor dead ahead easily, thereby influences image quality; 3) this camera volume is bigger than normal, and structure is not compact.
Summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, focusing speed fast and focusing accurately, can shoot the computer camera of picture rich in detail.
A kind of computer camera, comprise lens cone seat, lens barrel, be located at the optical lens parts in the lens barrel and be positioned at the photoelectric sensor at optical lens parts rear, described lens cone seat is provided with threaded hole, the outside surface of described lens barrel is provided with screw thread, the lens barrel tail end is nested in the threaded hole and with lens cone seat and is threaded, the front end of lens barrel protrudes from lens cone seat and the lens barrel gear is installed, and also is provided with the focusing gear on the described lens cone seat, and this focusing gear is meshed with described lens barrel gear.
The utility model compared with prior art has following advantage: the utility model lens barrel tail end is threaded with lens cone seat, and the front end of lens barrel protrudes from lens cone seat and the lens barrel gear is installed, and this focusing gear is meshed with described lens barrel gear.Stir the focusing gear, lens barrel gear driven lens barrel rotates together, and the lens barrel revolution is moving to advance or a slow astern pitch once enclosing, thereby it is very accurate that lens barrel is moved forward and backward, and realizes fast, accurately focusing, and shoots picture rich in detail, and is simple in structure.
Described lens cone seat is provided with two threaded holes, described lens barrel comprises long lens tube and short-focus mirror tube, long lens tube and short-focus mirror tube branch are installed in two threaded holes, and long-focus optical lens parts wherein are housed in the long lens tube, low beam is housed in the short-focus mirror tube learns lens assembly.Both near objects can be taken, monitoring distant objects, perfect in shape and function can be taken again.Only just can drive two lens barrel gears and rotate the realization focusing by a focusing gear, simple and compact for structure.
Be provided with two catoptrons between burnt optical lens parts of described length and the photoelectric sensor, two catoptrons are parallel to each other and front and back are staggeredly arranged.Increase the distance of light, can make camera integral body more flat, structure is compact more, volume-diminished.
Described photoelectric sensor is installed on the slide plate that is slidingly connected with lens cone seat, and the bottom of slide plate is provided with a slide block, stirs this slide block and can make photoelectric sensor be positioned at the dead astern of long burnt optical lens parts or short burnt optical lens parts.The utility model need not the accommodation reflex mirror, only needs the adjusting slider position, even there is dust to fall, also can drop on the rear of photoelectric sensor, can not be bonded at the front of photoelectric sensor, thereby guarantees image quality.
