Abstract
The utility model provides a camera lens which is convenient to install. The camera lens comprises a lens cone and a lens body, wherein the lens cone can be rotationally arranged at the inner side of the lens body; one of the outer side wall of the periphery of the lens cone or the inner side wall of the periphery of the lens body is provided with at least three guide bars which are uniformly distributed along a peripheral direction; and the guide bars extend entirely or along an axial part.
Description
Technical field
The utility model relates to a kind of camera lens, is the ingredient of video camera.
Background technology
Video camera generally partly is made up of camera lens, imageing sensor, sound transducer, A/D converter, video/audio scrambler, controller, the webserver, external alert, control interface etc.Wherein:
1, camera lens is as the front end component of camera lens, fixed aperture, auto iris, autozoom arranged, kind such as become doubly automatically, and it is identical with analog video camera.
2, imageing sensor has CMOS and two kinds of patterns of CCD.CMOS is a CMOS, and CMOS utilizes silicon and these two kinds of semiconductors that element is made of germanium, realizes basic function by CMOS is upward electronegative with transistor positively charged; Ccd image sensor is made of photoelectric diode that is two-dimensional arrangements on monocrystalline silicon substrate and transmission circuit thereof, and the equipment that transmits excellent image quality usually all adopts ccd image sensor, pays attention to the product of power consumption and cost and then selects cmos image sensor.
3, A/D converter is that image is become digital signal with analog signal conversion such as sound.Based on the image sensor module of CMOS pattern the interface of Direct Digital signal output is arranged, need not A/D converter; And based on the image sensor module of the CCD pattern interface if any Direct Digital output, also need not A/D converter, but, have only the simulation output interface because this module is primarily aimed at the analog video camera design, change so need carry out A/D.
4, image, vocoder, picture coding compress technique have two kinds: a kind of is the hardware encoding compression, is about to coding compression algorithm and is solidificated on the chip; Another kind is based on the software coding compression of DSP, and promptly running software carries out the encoding compression of image on DSP; Equally, the compression of sound also can be adopted hardware encoding compression and software compression, and its coding standard has forms such as MP3.
5, controller is the heart of camera lens, and it is bearing the management and the Control work of camera lens.If the hardware-compressed coding, controller is an individual components; If the software coding compression, controller is the DSP of operation encoding compression software, and promptly the two integrates.
6, the webserver provides the network function of video camera, it has adopted associated the Internet protocol such as RTP/RTCP, UDP, HTTP, TCP/IP, allow the user to use standard browser video camera to be conducted interviews, watch the camera lens and the The Cloud Terrace of realtime graphic and control video camera according to the IP address of camera lens from the PC of oneself.
7, external alert, control interface: video camera is used for engineering practical external interface is provided, and as 485 interfaces of control The Cloud Terrace, is used for the I/O mouth of alerting signal input and output.Find to have target to occur as infrared probe, the alert signal of transmitting messages is given video camera, and video camera is adjusted lens direction and video recording in real time automatically; On the other hand, when video camera has detected moving target when occurring, also can outwards send alerting signal.
Based on aforementioned each ingredient, the ultimate principle of video camera is: after camera lens input of picture signal process and voice signal are imported through microphone, be converted into electric signal by imageing sensor and sound transducer, A/D converter is converted to digital electric signal with analog electrical signal, carry out encoding compression through scrambler by certain coding standard again, under the control of controller, serve LAN (Local Area Network) or INTERNET by the webserver by certain procotol, controller can also receive alerting signal and outwards send alerting signal, and sends control signal on request.
Wherein, described camera lens generally comprises lens barrel and shank two parts, and eyeglass is located on the lens barrel, and lens barrel is located on the shank rotatably, and when lens barrel rotated with respect to shank, lens barrel moving linearly was simultaneously realized zoom and focusing.Employing face contacts between the known camera lens, its lens barrel lateral wall and shank, needs bigger moment when lens barrel moves with respect to shank when focusing like this, need spend more time when accurate focusing.
The utility model content
The purpose of this utility model provides a kind of light camera lens flexibly of adjusting.
The technical scheme that the utility model adopted is such: a kind of camera lens, comprise lens barrel and shank, described lens barrel is located at the shank inboard rotationally, one in described lens barrel periphery wall or the shank inside circumference wall which is provided with along three uniform gib blocks of circumferential direction at least, and described each gib block partly or entirely extends vertically.
Above-mentioned camera lens, described gib block are located on the lens barrel periphery wall.
Above-mentioned camera lens, the quantity of described gib block are four.
Above-mentioned camera lens, described gib block are located on the shank inside circumference wall.
Above-mentioned camera lens, the quantity of described gib block are four.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: because contact area makes into now less than 20% by original 100% between lens barrel and the shank, like this between lens barrel and the shank just seldom a part contact, friction force reduces greatly, adjustment is got up very convenient.

Fig. 2 is the lens construction synoptic diagram of the utility model embodiment two.
Embodiment
With reference to figure 1, embodiment one discloses a kind of camera lens, comprise lens barrel 1 and shank 2, described shank 2 inside circumference walls have can ccontaining lens barrel 1 the hole, described lens barrel 1 periphery wall is provided with the gib block 11 of four part extensions vertically, described each gib block 11 evenly distributes along lens barrel 1 circumferencial direction, part extension described here is meant in whole lens barrel 1 axial stroke scope, the length that gib block 11 extends is enough to play guide effect and gets final product, and the outside of described each gib block 11 is along contacting setting with the madial wall of shank 2.
With reference to figure 2, embodiment two discloses another kind of camera lens, comprise lens barrel 3 and shank 4, described shank 4 inside circumference walls have can ccontaining lens barrel 3 the hole, be provided with four gib blocks 41 in the described hole to the radially inner side projection, described each gib block 41 evenly distributes and axially whole the extension along shank 4 circumferencial directions, and described lens barrel 3 periphery walls contact setting with each gib block 41 radially inner side.
Claims (5)
1. camera lens, comprise lens barrel and shank, described lens barrel is located at the shank inboard rotationally, it is characterized in that: one in described lens barrel periphery wall or the shank inside circumference wall which is provided with along three uniform gib blocks of circumferential direction at least, and described each gib block partly or entirely extends vertically.
