Specific embodiment
The illustrative embodiments of the utility model are described in detail with reference to the accompanying drawings.To illustrative embodiments
Description merely for the sake of demonstration purpose, and be definitely not limitation to the utility model and its application or usage.
Fig. 1 is the schematic, exploded for showing adjustable dim light mirror according to the present utility model;Fig. 2 is shown according to originally practical
The schematic, exploded of novel adjustable dim light mirror and camera lens assembly;Fig. 3 be show it is according to the present utility model adjustable in Fig. 2
Dim light mirror be assembled on camera lens after schematic perspective view.
As shown in fig. 1, adjustable dim light mirror according to the present utility model includes: cover 2, the first rotating ring 3, first polarization
Eyeglass 4, the second rotating ring 5 and the second polarized lenses 6.Cover 2 is rendered as tubular frustum-like shape, that is, the end face at the both ends of cover 2
Area is different.It may also be said that cover 2 includes the lesser first end 23 of area and the biggish the second end 24 of area.Cover 2
First end 23 is provided with the first threaded joints 21, for being connected to the camera lens 1 of camera, as shown in Figure 2.The of cover 2
Two ends 24 are provided with the second threaded joints 22, for being connected to the first rotating ring 3, as shown in figs. 1 and 2.That is, cover 2
Camera lens 1 and the first rotating ring 3 are connected respectively to by the first threaded joints 21 and the second threaded joints 22.Specifically,
One rotating ring 3 includes the first rotating ring threaded joints 31, can rotate 360 degree relative to cover 2 with the first rotating ring 3
Mode is connect with the second threaded joints 22 of cover 2.
First polarized lenses 4 are fixedly attached in the first rotating ring 3 by the modes such as be clasped.For example, as an example,
First rotating ring 3 is internally provided with card slot, and the first polarized lenses 4 can be by being fixedly attached to the first rotating ring 3 in insertion card slot.
Thus when the first rotating ring 3 of turn, the first polarized lenses 4 can be driven to rotate together.The second rotation is provided on second rotating ring 5
Change threaded joints 51 are connect in a manner of for being connected through a screw thread with the first rotating ring 3.For example, as an example, first
Rotating ring 3 includes internal screw thread, and the second rotating ring threaded joints 51 on the second rotating ring 5 are external screw thread, from there through inside and outside
Second rotating ring 5 is connected to the first rotation in a manner of it can be rotated 360 degree relative to the first rotating ring 3 by the mode of threaded connection
On ring 3.Similar with the first polarized lenses 4, the second polarized lenses 6 are also to be fixedly attached to second by the modes such as be clasped
In rotating ring 5.For example, the second polarized lenses 6 can be by being embedded in card slot as an example, the second rotating ring 5 is internally provided with card slot
Inside it is fixedly attached to the second rotating ring 5.Thus when the second rotating ring 5 of turn, the second polarized lenses 6 can be driven to rotate together.
The schematic perspective view that adjustable dim light mirror according to the present utility model is assembled on camera lens 1 is shown in Fig. 3.In reality
Border can pass through turn the first rotating ring 3 and/or the second rotating ring in use, after adjustable dim light mirror is installed on camera lens 1
5 angle of cut or angle difference to rotate the first polarized lenses 4 and/or the second polarized lenses 6 to realize two polarized lenses, thus
The amount of the light of filtering is also different, has reached different grades of dimming effect.Specific explanations are folded mutually when a pair of of linear polarization eyeglass
The angle in use, between two polariscopic polarization directions of change is closed, its total light resistance rate can be made to change.When the two polarization direction that
When this is identical, total light resistance rate is minimum;With the increase of the angle of the two polarization direction, total light resistance rate is also more and more big;Work as the two
When polarization direction is vertical each other, total light resistance rate is maximum.It can get as a result, by the linear polarization eyeglass that two panels overlaps a series of
Light resistance rate value realizes the dimming effect of different stage.
As noted previously, as the area of two end faces of cover 2 is different, so adjustable dim light mirror according to the present utility model
The first polarized lenses 4 and the sizes of the second polarized lenses 6 be all larger than the size of camera lens 1.Preferably, the ruler of polarized lenses 4 and 6
Very little is 2 times of the size of camera lens 1.The edge part of camera lens 1 will not shut out the light into camera lens as a result, so that dimming effect is equal
It is even, dark angle is not generated.
Further, since the cover 2 of adjustable dim light mirror according to the present utility model has tubular frustum-like shape structure, so this can
Adjusting and reducing light microscopic can be adapted for mounting to reach dimming effect on spherical surface camera lens, but also have the function of protecting camera lens, answer
With in extensive range.
In addition, as previously described, because the first rotating ring 3 and the second rotating ring of adjustable dim light mirror according to the present utility model
5 are able to drive the rotation of the first polarized lenses 4 and the second polarized lenses 6, thus, it is possible to change the angle of cut of two polarized lenses, from
And different amounts of incident ray can be filtered, achieve the effect that multistage dim light.
Although the utility model is described referring to illustrative embodiments, but it is to be understood that the utility model
It is not limited to the specific embodiment be described in detail and shown in text, in the feelings without departing from claims limited range
Under condition, those skilled in the art can make various changes to the illustrative embodiments.These changes should all fall into this reality
With novel protection scope.
