Description
Technical field
The present invention relates to a kind of filter group, espespecially a kind of two ring type filter groups that can be conveniently adjusted filtering effects.
Background technique
Filter is that a kind of radiography assisting device being installed in front of camera lens also can other than it can be used to protect camera lens
Selective absorbing is carried out to the different-waveband of light, to form special effect of shadow on photographic work.General common filter
Mirror such as polariscope or dim light mirror, the principle of polariscope are mainly designed to that the light of a certain optical axis is only allowed to pass through, will not have
The natural light of deflection polarity is converted into polar biased light, therefore polariscope can be the reflector filter on non-metallic object surface, the water surface etc.
It eliminates, keeps color more bright-coloured, and dim light mirror is then that can reduce into light quantity, therefore camera can be helped to reduce shutter speed, strong
In the case that light irradiates, large aperture still can be used to take the effect of the shallow depth of field.A piece of filter is only installed in a previous filter group,
Although the filter group of multiple and different effects can be overlapped using to generate required effect of shadow by user, such to make
With other than it must carry multiple filter groups, also angle coverage being caused to contract because multiple filter groups are overlapped the shortcomings that mode
It is small, therefore someone just designed a kind of filter group for being installed with two panels filter later.
The position that the filter group for being installed with two panels filter of the prior art is designed primarily to wherein a piece of filter is fixed, is another
Piece filter can be rotated.For installing two panels polariscope in the filter group, when the optical axis of two polariscopes is parallel to each other, it can lead to
The light for crossing two polariscopes is most, therefore most bright polarization effect is presented；It, can be by two partially when the optical axis of two polariscopes is mutually perpendicular to
The light of light microscopic is minimum, therefore most dark polarization effect is presented.That is, by two polariscopes arrange in pairs or groups use, in addition to have filtering it is reflective,
Make except bright effect, also has both the effect of dim light, and the variation of the adjustable polarisation of filter group, dimming effect is main
It is orthogonal between 0 degree to 90 degree in the optical axis of the two polariscopes optical axis to two polariscopes that is parallel to each other.
However, criss-cross half-light can be generated when position of the relative angle of the optical axis of two polariscopes at 0 degree and 90 degree
Block, commonly referred to as " cross pattern phenomenon ", and the rotation due to the filter group of the prior art for the rotatable polariscope
There is no restriction for angle, therefore user is when adjusting the angle of the rotatable polariscope, it is necessary to which carefully rotating this can turn
Dynamic polariscope, in order to avoid generate the cross pattern phenomenon.Furthermore the filter group of the prior art is that two polariscope clamping positions exist
Between several ring frames, the rotatable polariscope must be driven by rotating specific ring frame when use, and due to those ring frames
Width it is narrow be difficult to be groped with hand to the ring frame that can drive the rotatable polariscope so that user often has in operation
Problem.As described above, therefore the filter group of the prior art has its inconvenience on operating with, need further to improve.
Summary of the invention
In view of the problems of aforementioned prior art, the purpose of the present invention is to provide a kind of two ring type filter groups,
The rotational angle of its rotatable filter is restricted, and to avoid cross pattern phenomenon is generated, therefore can be operated with convenient for user.
To achieve the above object, the technological means that the present invention uses is to provide a kind of two ring type filter groups, wherein should
Two ring type filter groups include:
One stop collar, a lock ring, a fixed filter, an adjustment ring, rotation filter, at least a drive rod and a pressure ring,
Wherein:
Ring portion, a socket ring portion and an at least arc guide barrel, the internal ring portion are connect with an internal ring portion, one group on the stop collar
It is radially extended, the rear side which connects ring portion from interior ring edge towards the stop collar of the internal ring portion is axially extending, the socket ring
The front side of portion from outer ring edge towards the stop collar of the internal ring portion is axially extending, which is formed through the socket ring portion
On, and the arc guide barrel extends around the center of circle of the socket ring portion；
The internal ring portion that the lock ring is set in the stop collar connects the outside of ring portion with group, and the lock ring and the stop collar are mutual
Snapping；
In the circular space of the interior ring edge for the internal ring portion that the fixation filter is located at the stop collar, and the fixation filter knot
Close the interior ring edge for being fixed on the internal ring portion；
The adjustment ring is located in the circular space of socket ring portion of the stop collar with being able to rotate, which has a court
To the interior side ring surface of the internal ring portion of the stop collar；
The rotation filter is located between the adjustment ring and the internal ring portion of the stop collar, and the rotation filter is combined and is fixed on
The interior side ring surface of the adjustment ring；
Each drive rod is through a corresponding arc guide barrel and is fixed in the adjustment ring；
The pressure ring is installed in the circular space of socket ring portion of the stop collar, and the pressure ring and the socket ring portion with
The mode that can be dismantled is mutually assembled, and the adjustment ring and rotation filter are clamped and limit the internal ring portion in the pressure ring and the stop collar
Between.
Two ring types filter group as described above, wherein the radian of each arc guide barrel is respectively less than 90 degree；Alternatively, each arc
The radian of shape guide groove is 90 degree.
Two ring types filter group as described above, wherein the quantity of the arc guide barrel of stop collar is two, and two arcs are led
Slot is located at the opposite sides of the socket ring portion, and the quantity of drive rod is two, and two drive rods extend through two arcs
Guide groove is simultaneously fixed in the adjustment ring.
Two ring types filter group as described above, wherein fixed filter is combined by viscose with the internal ring portion of the stop collar
It is fixed, filter, which is rotated, by viscose combines fixation with the adjustment ring.
Two ring types filter group as described above, wherein lock ring has one to combine ring portion, this combines ring portion to protrude out shape along axial direction
At in the rear end of the lock ring, and the lock ring is circumferentially positioned at the group of the stop collar and connects around ring portion, this combines the outer of ring portion
External screw thread is formed on side.
Two ring types filter group as described above, wherein fixed filter is polariscope with rotation filter.
It is an advantage of the current invention that the arc when above-mentioned fixed filter and rotation filter are polariscope, on the stop collar
Other than it can guide drive rod adjustment polarisation and dimming effect, the radian of the arc guide barrel is limited in be produced shape guide groove
Between the two limit positions of raw cross pattern phenomenon, the rotational angle range of the drive rod can be limited, accordingly directly to avoid making
User is adjusted to the rotation filter and fixed filter that can generate cross when driving the rotation filter to rotate by the drive rod
The relative angular position of line phenomenon, and the drive rod of the protrusion can allow user clearly to find can drive the rotation filter
The position of rotation, thus two ring type filter groups of the invention operate with it is upper quite convenient.
