Description
Technical field
The present invention is Application No. 201310754170.4, filing date December 31 in 2013
Day, the division of the application for a patent for invention of entitled " a kind of self-locking video camera external focusing device "
Application.The present invention relates to video camera, particularly to a kind of self-locking video camera external focusing device.
Background technology
Traditional video camera is when shooting, and object is to become with the relative distance i.e. object distance of video camera
Change.In order to make the object of different object distances can be obtained clearly on Image Plate by camera lens
Image, it is necessary to carry out focussing process.Current focussing process generally uses following two mode to enter
OK: one, changing the focusing mode of image distance, the focal length keeping camera lens is constant, by adjusting whole group
The axial location of camera lens, thus change the distance between camera lens and Image Plate, i.e. change image distance and obtain
To image clearly.This focusing mode need to move whole group of camera lens, due to the eyeglass of whole group of camera lens
Many, volume is big, so focus adjusting mechanism is complicated.Two, change the outer focusing mode of focal length, pass through
The axial location of certain group eyeglass in moving lens, thus change in camera lens between eyeglass relative away from
From, i.e. change lens focus and obtain image clearly.Though this whole group of camera lens of outer focusing mode can
Remaining stationary as, focus adjusting mechanism is relatively simple, but its structural instability, it is impossible to ensure the imaging of camera lens
Quality is in optimum state.With reference to Fig. 1, existing video camera external focusing device includes for adjusting
The drive mechanism 1 ' of the axially opposing distance of eyeglass and the toothed disc of drive mechanism 1 ' on whole camera lens
Gear shaft 2 ', 3 ' that 11 ', 12 ' are meshed and be connected with gear shaft 2 ', 3 ' and control
The guiding mechanism focused outside realizing that gear shaft 2 ', 3 ' rotates.The investigation mission outside the city or town of this kind of structure
Coke installation when adjusting the axially opposing distance of eyeglass on camera lens, the toothed disc of drive mechanism 1 '
11 ', 12 ' engage each other with gear shaft 2 ', 3 ' and to be connected so that it adjusts gear when rotating
Between dish and gear shaft exist a running clearance problem so that its cannot precise positioning, make
Become bigger position deviation so that in camera lens, the relative distance of eyeglass is unable to reach optimal imaging position
Put so that final shooting image quality is the highest, though outside prior art also some other mode
Focusing structure, but structure is complicated, and cost is high.
Summary of the invention
Therefore, for above-mentioned problem, the present invention propose a kind of simple in construction, cost low,
Realize the precise positioning of outer focusing, improve the self-locking video camera of shooting image quality.
For realizing above-mentioned technical problem, the solution that the present invention takes is:
A kind of self-locking video camera, including camera lens and self-locking video camera external focusing device, self-locking
Only video camera external focusing device includes for adjusting the axially opposing distance of eyeglass on described camera lens
Drive mechanism (1), drive mechanism (1) includes two worm gear dishes (11), (12), two snails
Wheel disc (11), (12) obvolvent relatively are on the outer circumference surface of described camera lens；
Also include worm screw (2), (3) and and the worm screw being meshed with worm gear dish (11), (12)
(2), (3) one end be connected and for controlling worm screw (2), guiding mechanism (4) that (3) rotate；
Described guiding mechanism (4) includes that two are connected with worm screw (2), (3) one end respectively
Rotation slot (41), (42).
Said two worm screw (2), the axis of (3) are parallel to each other, and said two worm screw (2),
(3) axis axis with described camera lens respectively is mutually perpendicular to.
Described rotation slot (41), (42) are the cylinder being provided with interior hexagonal groove.
By use preceding solution, the invention has the beneficial effects as follows: by use worm gear with
The rotation blind-mate of worm screw, controls worm screw by guiding mechanism and rotates, then driven by worm screw
Worm gear wheel adjusts the axially opposing distance of eyeglass on camera lens so that video camera realizes the essence of outer focusing
Certainly position, make the relative distance of eyeglass in camera lens reach optimal imaging position, substantially increase
Shooting image quality, present configuration is simple simultaneously, and cost is low, the focusing side of video camera
Just, Stability Analysis of Structures, can wide popularization and application.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing video camera external focusing device；
Fig. 2 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, the present invention is further described.
With reference to Fig. 2, a kind of self-locking video camera disclosed in the embodiment of the present invention, including for adjusting
The drive mechanism 1 of the axially opposing distance of eyeglass and the worm gear dish 11 of drive mechanism 1 on whole camera lens,
Worm screw 2,3 that 12 are meshed and be connected with worm screw 2,3 one end and for control worm screw 2,
3 rotate guiding mechanisms 4, described guiding mechanism 4 include two respectively with worm screw 2,3 one end
The rotation slot 41,42 being connected, described rotation slot 41,42 is and is provided with interior hexagonal groove
Cylinder.
The present invention is by using the rotation blind-mate of worm gear and worm screw, by guiding mechanism control
Worm screw processed rotates, then is driven worm gear wheel to adjust the axially opposing distance of eyeglass on camera lens by worm screw,
Video camera is made to realize the precise positioning of outer focusing, the relative distance of eyeglass in camera lens is reached
Optimal imaging position, substantially increases shooting image quality, and present configuration is simple simultaneously, makes
Valency low cost, the focusing of video camera is convenient, Stability Analysis of Structures, can wide popularization and application.
Although specifically show and describe the present invention in conjunction with preferred embodiment, but without departing from institute
In the scope of the invention that attached claims are limited, in the form and details can be to this
Invention makes a variety of changes, and is protection scope of the present invention.
