Abstract
The utility model provides a manual optical focusing lens comprising a magnification zoom lens group, a focusing lens group, a zoom linkage element and a focusing linkage element, wherein the magnification zoom lens group is movably connected with the focusing lens group; the zoom linkage element is assembled on the magnification zoom lens group and controls the magnification zoom lens group to zoom; and the focusing linkage element is assembled on the focusing lens group and controls the focusing lens group to focus. The manual optical focusing lens provided by the utility model has the advantages because the zoom linkage element is assembled on the magnification zoom lens group and the focusing linkage element is assembled on the focusing lens group so that all the operation processes for magnification and focusing are prevented from using a stepper motor or a drive chip. The structure of the utility model matching with the computing power of the main chip of a camera can realize zooming and focusing functions which is the same with an existing optical zoom camera, and is low in cost, and the camera has high stability in zooming and focusing processes.
Description
Technical field
The utility model relates to the camera lens of camera, relates in particular to manual optical focusing camera lens.
Background technology
The camera lens of overwhelming majority focusing mode all is to cooperate chip for driving to carry out control with step motor in the existing market; So not only very high to the accuracy requirement of mould; And the design in the mechanism also is quite complicated, and the original paper cost that relates to is quite high, and the collocation of step motor and gear drives is afraid of to run into most collision; In case have the effect of the whole group focusing of the design load of a little skew will entanglement, even the jammed phenomenon of camera lens arranged.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of manual optical focusing camera lens.
The utility model provides a kind of manual optical focusing camera lens; Comprise multiplying power zoom lens group, focus lens group, zoom STATEMENT OF FEDERALLY SPONSORED, focusing STATEMENT OF FEDERALLY SPONSORED; Said multiplying power zoom lens group and said focus lens group are for flexibly connecting; Said zoom STATEMENT OF FEDERALLY SPONSORED is sleeved on the said multiplying power zoom lens group and controls said multiplying power zoom lens group and carry out zoom, and said focusing STATEMENT OF FEDERALLY SPONSORED is sleeved on the said focus lens group and controls said focus lens group and focus.
As the further improvement of the utility model, this manual optical focusing camera lens also comprises and links to each other with said focusing STATEMENT OF FEDERALLY SPONSORED and control the governor motion that said focusing STATEMENT OF FEDERALLY SPONSORED is moved.
Further improvement as the utility model; Said governor motion comprises focusing gear, finger shifting part; Said focusing STATEMENT OF FEDERALLY SPONSORED is provided with the focusing linkage gear, and said focusing gear links to each other with said finger shifting part, and said focusing gear and said focusing linkage gear are meshing with each other.
As the further improvement of the utility model, this manual optical focusing camera lens also comprises lens mount, circuit board, sensor, and said multiplying power zoom lens group and said focus lens group are installed on the said lens mount, and said sensor is arranged on the said circuit board.
As the further improvement of the utility model, said finger shifting part comprises the bar shaped bar or rotates and turn round.
The beneficial effect of the utility model is: because said zoom STATEMENT OF FEDERALLY SPONSORED is sleeved on the said multiplying power zoom lens group; Said focusing STATEMENT OF FEDERALLY SPONSORED is sleeved on the said focus lens group; So whole operating processes of enlargement ratio and focusing have all been avoided use step motor or chip for driving; The computing power of the master chip of respective outer side edges camera through the utility model own has just been accomplished as the existing the same zoom focus function of optical zoom camera; And cost is low, and camera stability in zoom and focus process is high.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model.
Embodiment
As shown in Figure 1; The utility model discloses a kind of manual optical focusing camera lens; Comprise multiplying power zoom lens group 1, focus lens group 2, zoom STATEMENT OF FEDERALLY SPONSORED 3, focusing STATEMENT OF FEDERALLY SPONSORED 5; Said multiplying power zoom lens group 1 is flexible connection with said focus lens group 2; Said zoom STATEMENT OF FEDERALLY SPONSORED 3 is sleeved on the said multiplying power zoom lens group 1 and controls said multiplying power zoom lens group 1 and carry out zoom, and said focusing STATEMENT OF FEDERALLY SPONSORED 5 is sleeved on the said focus lens group 2 and controls said focus lens group 2 and focus.
Because said zoom STATEMENT OF FEDERALLY SPONSORED 3 is sleeved on the said multiplying power zoom lens group 1; Said focusing STATEMENT OF FEDERALLY SPONSORED 5 is sleeved on the said focus lens group 2; So whole operating processes of enlargement ratio and focusing have all been avoided use step motor or chip for driving; The computing power of the master chip of respective outer side edges camera through the utility model own has just been accomplished as the existing the same zoom focus function of optical zoom camera, and cost is low, and camera stability in zoom and focus process is high.
This manual optical focusing camera lens also comprises and links to each other with said focusing STATEMENT OF FEDERALLY SPONSORED 5 and control the governor motion that said focusing STATEMENT OF FEDERALLY SPONSORED 5 is moved.
Said governor motion comprises focusing gear 7, finger shifting part 6, and said focusing STATEMENT OF FEDERALLY SPONSORED 5 is provided with focusing linkage gear 8, and said focusing gear 7 links to each other with said finger shifting part 6, and said focusing gear 7 is meshing with each other with said focusing linkage gear 8.Through finger shifting part 6 focusing gear 7 is rotated,, rotate so drive focusing linkage gear 8 through focusing gear 7 because focusing gear 7 is meshing with each other with said focusing linkage gear 8.
This manual optical focusing camera lens also comprises lens mount 9, circuit board 11, sensor 10, and said multiplying power zoom lens group 1 is installed on the said lens mount 9 with said focus lens group 2, and said sensor 10 is arranged on the said circuit board 11.
Said finger shifting part 6 comprises the bar shaped bar or rotates and turn round.
During use; Be printed on the scale of corresponding enlargement ratio on the zoom STATEMENT OF FEDERALLY SPONSORED 3; The user can pass through hand, reverses zoom group STATEMENT OF FEDERALLY SPONSORED 3 and reaches to the feasible picture amplification of obtaining of the enlargement ratio scale of correspondence, regulates corresponding focal length through the finger shifting part 6 on the camera side again and makes picture clear.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
