Abstract
The utility model discloses a chute structure of lens camera lens, include that the light filter base reaches the light filter support that produces the relative slip with the light filter base, be equipped with the recess guide rail on the light filter base, be equipped with the ball bowl on the light filter support, be equipped with the ball between ball bowl and recess guide rail. This chute structure of lens camera lens sets up between light filter base and light filter support and does benefit to gliding ball, has reduced frictional force, and is more smooth and easy when not only making whole mechanism motion, but also has improved life. The utility model is suitable for an optics field.
Description
Technical field
This utility model relates to optical field, particularly relates to the sliding groove structure of a kind of lens。
Background technology
Lens can by making the light path that optical component entered, exited lens change optical characteristics。Such as, cutoff filter (the Infra-redCutFilter through characteristic of lens can be changed, IRCutFilter), polarizer (PolarizationFilter), dim light mirror (NeutralDensityFilter, the various filters such as NDFiler), changing the zoom lens (ConversionLens) at the photography multiplying power of lens, focal length, visual angle, the bore of lens (aperture) can be changed and regulate the lens with additional function。These lens include manually making optical component to enter, the type of exit optical and by the electronic type making optical component entrance, exit optical, the former has the problem that operation is comparatively loaded down with trivial details, the latter is because needing to cause the maximization of lens, cost up with special driver。
At present, optical component holding frame and linkage component cooperation aspect, can form as one with cam with a side, the mode that the opposing party and cam path form as one is arranged, this mode is arranged, easy wear cam groove in long-term motion, the reduction in cam path service life reduces the service life of lens on the whole。
Utility model content
For solving the problems referred to above, this utility model provides the sliding groove structure of a kind of lens reducing abrasion。
This utility model solves its technical problem and be the technical scheme is that
The sliding groove structure of a kind of lens, produces the optical filter support of relative sliding including optical filter pedestal and with optical filter pedestal, and optical filter pedestal is provided with grooved rail, and optical filter support is provided with ball bowl, is provided with ball between ball bowl and grooved rail。
It is further used as the improvement of technical solutions of the utility model, ball bowl is additionally provided with tapped through hole, in tapped through hole, be provided with the nut for regulating ball frictional force。
The beneficial effects of the utility model: the sliding groove structure of this lens, arrange between optical filter pedestal and optical filter support and are beneficial to the ball of slip, decrease frictional force, more smooth and easy when not only making whole mechanism kinematic, but also improve service life。
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is this utility model embodiment overall structure schematic diagram；
Fig. 2 is this utility model embodiment overall structure sectional view。
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to be completely understood by the purpose of this utility model, feature and effect。Obviously; described embodiment is a part of embodiment of the present utility model, rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the premise not paying creative work, belong to the scope of this utility model protection。
With reference to Fig. 1, Fig. 2, this utility model is the sliding groove structure of a kind of lens, the optical filter support 10 of relative sliding is produced including optical filter pedestal 7 and with optical filter pedestal 7, optical filter pedestal 7 is provided with grooved rail 71, optical filter support 10 is provided with ball bowl, is provided with ball 102 between ball bowl and grooved rail 71。
The sliding groove structure of this lens, arranges between optical filter pedestal 7 and optical filter support 10 and is beneficial to the ball 102 of slip, decrease frictional force, more smooth and easy when not only making whole mechanism kinematic, but also improves service life。
As this utility model preferred embodiment, ball bowl is additionally provided with tapped through hole 101, in tapped through hole 101, is provided with the nut for regulating ball 102 frictional force。
As this utility model preferred embodiment, shoe cream room can be set in ball bowl, provide lubricant grease for ball。
This utility model includes, the optical filter pedestal 7 of plastic material, plastic material optical filter support 10, cutoff filter 14 is fixed on optical filter support 10,71 is grooved rail, contact with the ball face of 102 balls, adjustable nut is set in tapped through hole 101, controls the laminating of ball and grooved rail；In whole process, by the adjustable hex nut in the optical filter support 10 of plastic material make ball 102 and grooved rail 71 fully in contact with, and compared in the past, mechanism friction power is also little, fluent movements, precisely。Also improve service life simultaneously。
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art it may also be made that equivalent variations or replacement under the premise without prejudice to this utility model spirit, and these equivalent deformation or replacement are all contained in the application claim limited range。
