Description
Technical field
The present invention is application No. is 201310754170.4, and the applying date is on December 31st, 2013, a kind of entitled " self-locking
The divisional application of the application for a patent for invention of only video camera external focusing device ".The present invention relates to video camera, more particularly to a kind of self-locking
Only video camera external focusing device.
Background technology
When shooting, relative distance, that is, object distance of object and video camera is variation to traditional video camera.In order to make not
Object with object distance can obtain clearly image by camera lens on Image Plate, it is necessary to carry out focussing process.Current tune
The burnt following two modes of process generally use carry out：One, change the focusing mode of image distance, keeps the focal length of camera lens constant, pass through
The axial position for adjusting whole group camera lens changes image distance and obtains clearly shadow to change the distance between camera lens and Image Plate
Picture.This focusing mode need to move whole group camera lens, since the eyeglass of whole group camera lens is more, volume is big, so focus adjusting mechanism is complicated.
Two, change the outer focusing mode of focal length, by the axial position of certain group eyeglass in moving lens, to change in camera lens eyeglass it
Between relative distance, that is, change lens focus obtain clearly image.Though this outer focusing mode whole group camera lens can remain stationary as,
Focus adjusting mechanism is simpler, but its structural instability, can not ensure that the image quality of camera lens is in optimum state.It is existing with reference to figure 1
Video camera external focusing device include for adjust the transmission mechanism 1 ' of the axially opposing distance of eyeglass on camera lens, with transmission mechanism 1 '
The gear shaft 2 ', 3 ' that is meshed of toothed disc 11 ', 12 ' and be connected with gear shaft 2 ', 3 ' and control the rotation of gear shaft 2 ', 3 '
The adjustment mechanism for realizing outer focusing.The external focusing device of such structure axially opposing distance of eyeglass on adjustment camera lens
When, toothed disc 11 ', 12 ' and the intermeshing of gear shaft 2 ', 3 ' of transmission mechanism 1 ' connect so that toothed disc when it adjusts rotation
There are problems that a running clearance between gear shaft so that its can not precise positioning, cause larger position deviation so that
The relative distance of eyeglass is unable to reach optimal imaging position in camera lens so that final camera shooting image quality is not high, the prior art
Though the also outer focusing structure of some other modes, complicated, of high cost.
Invention content
Therefore, for above-mentioned problem, the present invention proposes a kind of essence simple in structure, cost is low, realization is focused outside
Certainly position, improve camera shooting image quality the self-locking video camera external focusing device with worm gear disk and worm screw.
To realize above-mentioned technical problem, the solution that the present invention takes is：
A kind of self-locking video camera external focusing device with worm gear disk and worm screw, including it is used to adjust eyeglass axis on camera lens
To the transmission mechanism (1) of relative distance, the worm screw (2) being meshed with the worm gear disk (11) of transmission mechanism (1), (12), (3) and with
Worm screw (2), (3) one end be connected and be used to control worm screw (2), (3) rotation adjustment mechanism (4)；
The worm gear disk on the camera lens is two, and two worm gear disks (11), (12) are located at the outer of the camera lens relatively
On periphery.
Described two worm screws (2), (3) axis be mutually parallel.
Described two worm gear disks (11), (12) mutually stagger in Different Plane.
The adjustment mechanism (4) includes two rotation slots (41) being connected respectively with worm screw (2), (3) one end, (42).
Described two rotation slots (41), (42) be located at described two worm screws (2), (3) phase the same side end.
The rotation slot (41), (42) are to set reeded cylinder.
By using preceding solution, the beneficial effects of the invention are as follows：By using worm gear and worm screw rotation continuously
Gap coordinate, by adjusting mechanism controls worm screw rotate, then by worm screw drive worm gear rotation adjustment camera lens on eyeglass it is axially opposing away from
From so that video camera realizes the outer precise positioning focused, so that the relative distance of eyeglass reaches optimal imaging position in camera lens, greatly
Camera shooting image quality, while the configuration of the present invention is simple are improved greatly, cost is low, focusing convenience, the stable structure of video camera,
It can wide popularization and application.
Description of the drawings
Fig. 1 is the structural schematic diagram of existing video camera external focusing device；
Fig. 2 is the structural schematic diagram of the embodiment of the present invention.
Specific implementation mode
In conjunction with the drawings and specific embodiments, the present invention is further described.
With reference to figure 2, dress of focusing outside a kind of self-locking video camera with worm gear disk and worm screw disclosed by the embodiments of the present invention
It sets, includes for adjusting the transmission mechanism 1 of the axially opposing distance of eyeglass on camera lens, being nibbled with the worm gear disk 11 of transmission mechanism 1,12 phases
The worm screw 2,3 of conjunction and the adjustment mechanism 4 for being connected and be used to control the rotation of worm screw 2,3 with worm screw 2,3 one end, the adjustment mechanism
4 include two rotation slots 41,42 being connected respectively with worm screw 2,3 one end, and the rotation slot 41,42 is recessed equipped with interior hexagonal
The cylinder of slot.
The present invention is rotated by using the rotation blind-mate of worm gear and worm screw by adjusting mechanism controls worm screw, then
The axially opposing distance of eyeglass on worm gear rotation adjustment camera lens is driven by worm screw so that the outer precise positioning focused of video camera realization,
So that the relative distance of eyeglass reaches optimal imaging position in camera lens, camera shooting image quality, while knot of the present invention are substantially increased
Structure is simple, and cost is low, focusing convenience, the stable structure of video camera, can wide popularization and application.
Although specifically showing and describing the present invention in conjunction with preferred embodiment, the appended claims institute is not being departed from
In the scope of the invention of restriction, the present invention can be made a variety of changes in the form and details, be the guarantor of the present invention
Protect range.
