Abstract

The invention discloses a mechanism capable of accurately positioning a zooming position of a camera. The mechanism capable of accurately positioning the zooming position of the camera comprises a rotation ring, a support, a driven wheel, a potentiometer and a cover plate, wherein one end of the rotation ring and one end of the support are connected through a torsion spring, the potentiometer is fixed at the other end of the support, the potentiometer and the support are wrapped through the cover plate, and the driven wheel is fixed on the potentiometer. The mechanism capable of accurately positioning the zooming position of the camera is simple in structure. When a cloud platform controls the camera to zoom, a zooming ring on the camera can rotate, the zooming ring can synchronously drive the driven wheel, the driven wheel can drive the internal potentiometer during the rotation process, the potentiometer can transmit the current zooming position to the cloud platform, and then the cloud platform can know the current zooming position of the camera, the zooming position is stored, and in the next time, the preset zooming position can be directly called, and therefore accurate positioning for the zooming position of the common camera is achieved.

The content of the invention
Presetting bit cannot be set to common camera for existing head, disclosure of the invention one kind can be accurately positioned video camera change The mechanism of burnt position, realizes that presetting bit is set to common camera by head.
To achieve these goals, used technical scheme is invented as follows:
A kind of mechanism for being accurately positioned video camera zoom position, including swivel becket, support, with driving wheel, potentiometer and lid One end of plate, the swivel becket and support is connected with torsion spring, and the potentiometer is fixed on the other end of support, the potentiometer and Support is wrapped up by cover plate, described to be fixed on potentiometer with driving wheel.
Preferably, it is described to be rotary structure with driving wheel and potentiometer.
Further, the potentiometer is three layers of forge piece of step type structure, is foremost that, with driving wheel installation axle, centre is installation Axle.
Further, also including pad, spring, output shaft and nut, the installation axle of potentiometer is threadedly coupled with support, defeated Shaft be sleeved on potentiometer with driving wheel installation axle, then being fixed by pin, be sleeved on output shaft with driving wheel, pad set On output shaft, pad is embedded in in driving wheel, nut is locked in spring on output shaft, and the spring other end withstands pad.
Further, it is described to be provided with arc cam with driving wheel excircle.
Further, it is described to be provided with groove with driving wheel, a rubber ring is covered on groove.
Further, the material with driving wheel is rubber or other soft materials.
The beneficial effect of the invention:A kind of mechanism for being accurately positioned video camera zoom position of disclosure of the invention, when swivel becket is solid Regularly, support is subject to the elastic force of torsion spring, promotes support to turn right, and potentiometer is locked on support, and electricity is fixed on again with driving wheel On the device of position, with driving wheel as support turns right, the zoom ring of video camera is close to driving wheel.
Brief description of the drawings
Fig. 1 is the mechanism structure schematic diagram that invention can be accurately positioned video camera zoom position.
Fig. 2 is mechanism's scheme of installation that invention can be accurately positioned video camera zoom position.
Fig. 3 is mechanism's clutch protection schematic diagram that invention can be accurately positioned video camera zoom position.
Fig. 4 is schematic diagram of the invention with the embodiment of driving wheel one.
Fig. 5 is schematic diagram of the invention with another embodiment of driving wheel.
In figure, 1- swivel beckets, 2- torsion springs, 3- potentiometers, 4- supports, 5- is with driving wheel, 6- cover plates, 7- heads, 8- supporting plates, 9- Video camera, 10- axles, 11- pads, 12- springs, 13- nuts, 14- output shafts.
Specific embodiment
The technical scheme invented is described in detail below in conjunction with accompanying drawing, but the protection domain of invention is not limited to The implementation method, the multitude of different ways that can be defined by the claims and cover is implemented.
As shown in Figure 1, Figure 2 and Figure 3, a kind of mechanism for being accurately positioned video camera zoom position of disclosure of the invention, including turn Rotating ring 1, support 4, with driving wheel 5, potentiometer 3, cover plate 6, pad 11, spring 12, output shaft 14 and nut 13, the swivel becket 1 One end torsion spring 2 with support 4 is connected, and the potentiometer 3 is fixed on the other end of support 4, and the potentiometer 3 and support 4 are logical Cross cover plate 6 to wrap up, described to be fixed on potentiometer 3 with driving wheel 5, described to be rotary structure with driving wheel 5 and potentiometer 3, institute State the potentiometer 3 that cover plate 6 at least covers half, form fit.
As shown in figure 3, the potentiometer 3 is three layers of forge piece of step type structure, it is foremost that, with driving wheel installation axle, centre is installation Axle, the installation axle of potentiometer 3 is threadedly coupled with support 4, output shaft 14 be sleeved on potentiometer 3 with driving wheel installation axle, then Fixed by screw, be set with the output shaft 14 with driving wheel 5, pad 11 is set with the output shaft 14, pad 11 be embedded in In driving wheel 5, nut 13 locks spring 12 on the output shaft 14, and the other end of spring 12 withstands pad 11.
As shown in Fig. 2 video camera 9 is arranged on the supporting plate 8 of head 7, axle 10 is fixed on supporting plate 8, and swivel becket 1 is fixed on On axle 5, the zoom ring that video camera 9 is close to driving wheel 5 of upper end.
As shown in figure 5, in the present embodiment, it is described to be provided with arc cam with the excircle of driving wheel 5.
As shown in figure 4, as another embodiment, it is described to be provided with groove with driving wheel 5, a rubber is covered on groove Cushion rubber
The material with driving wheel 5 is rubber or other soft materials.
When the zoom ring of video camera 9 is rotated, with the concomitant rotation of driving wheel 5, zoom ring size ratio is much larger with driving wheel 5, when Zoom ring rotates one and encloses, and is accomplished by rotating several circles with driving wheel 5, that is, drive potentiometer 3 also to take a turn for the better several circles, and 3 turns of potentiometer When moving several circles, it is possible to go to terminal, continue easily to get worse potentiometer 3 if hardness is rotated;By the device of Fig. 3, with Driving wheel 5 is subject to the pressure of spring 12 so that with producing frictional force between driving wheel 5 and output shaft 14, when rotating with driving wheel 5, current potential The concomitant rotation of device 3, when potentiometer 3 turns to terminal, still hardness is rotated during with driving wheel 5, and potentiometer 3 is not just rotated further by, with dynamic Wheel 5 is from rotation.
Head 7 control 9 zoom of video camera when, the zoom ring on video camera 9 will be rotated, zoom ring can synchronously drive with Driving wheel 5, can drive the potentiometer 3 of inside, potentiometer 3 now zoom position can be transferred into cloud with driving wheel 5 in rotation process Platform 7, then head 7 know the zoom position of now video camera 9, after storage location, next time can call this presetting bit.
Above content is only the structure example and explanation to inventing, affiliated those skilled in the art couple Described specific embodiment is made various modifications or supplement or is substituted using similar mode, without departing from invention Structure surmounts scope defined in the claims, all should belong to the protection domain of invention.
