Abstract
The utility model relates to optical field, and especially a kind of even control rotates shade.It comprises outer shroud, inner ring, rotary screw, rotating shaft, polaroid polarization scale, outer shroud polaroid, inner ring polaroid, described outer shroud is connected with inner ring by rotating shaft, described rotary screw is portrayed in outer shroud, inner ring, and described helical scores is portrayed on swivel plate.Which overcome and adopt the problem such as adjustment obscurity size that traditional shading device can not be random, penetrating light intensity can be regulated easily.
Description
Technical field
The utility model relates to optical field, and especially a kind of even control rotates shade.
Background technology
In many technical fields, often need to control the power of light, such as, plant cultivation process, intensity of sunshine, on the impact of crop, need to control the illumination condition of different time sections, with the requirement of satisfied experiment.But the adjustment obscurity size that traditional shading device often can not be random, when the enhancing of outdoor light, adopts single equipment cannot reach the requirement of user, and then affects scientific experiment accuracy and preciseness.
Utility model content
The utility model is intended to solve the problem, and provides a kind of even control and rotates shade, and which overcome the problems such as the adjustment obscurity size that the traditional shading device of employing can not be random, its technical scheme adopted is as follows:
A kind of even control rotates shade, comprise outer shroud, inner ring, rotary screw, rotating shaft, polaroid polarization scale, outer shroud polaroid, inner ring polaroid, described outer shroud is connected with inner ring by rotating shaft, described rotary screw is portrayed in outer shroud, inner ring, and described outer shroud, inner ring are clear glass steel.
On technique scheme basis, described outer shroud polaroid, the angle that inner ring polaroid is corresponding are respectively the direction allowing light to pass through, and become single polarisation by rear light.
On technique scheme basis, the scale of described helical scores is spiral fashion, different from common ruler scale close-packed arrays, and the sparse arrangement of scale of helical scores, scale is spiral increase on swivel plate.
On technique scheme basis, described outer shroud polaroid, the polarization direction of inner ring polaroid are by being 0 ° → 90 ° → 0 ° → 90 ° → 0 °, to ensure that, in the process that inner ring polaroid rotates, the angle of the polarization direction of outer shroud polaroid, inner ring polaroid is consistent in different directions.
The utility model tool has the following advantages: reasonable in design, can easily regulate penetrating light intensity, workable, easy to carry.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, a kind of even control rotates shade, comprise outer shroud 1, inner ring 2, rotary screw 3, rotating shaft 4, polaroid polarization scale 5, outer shroud polaroid 6-a, inner ring polaroid 6-b, described outer shroud 1 is connected with inner ring 2 by rotating shaft 4, described rotary screw 3 is portrayed in outer shroud 1, inner ring 2, and described outer shroud 1, inner ring 2 are clear glass steel.
Preferably, between outer shroud 1, inner ring 2 except top is spun by rotating shaft 4, other position does not contact and inner ring 2 can 4 to rotate around the shaft.
Preferably, described outer shroud polaroid 6-a, the angle that inner ring polaroid 6-b is corresponding are respectively the direction allowing light to pass through, and become single polarisation by rear light.
Preferably, described outer shroud polaroid 6-a, the polarization direction of inner ring polaroid 6-b are by being 0 ° → 90 ° → 0 ° → 90 ° → 0 °, to ensure that, in the process that inner ring polaroid 6-b rotates, the angle of the polarization direction of outer shroud polaroid 6-a, inner ring polaroid 6-b is consistent in different directions.
In use, be placed in inner ring by needing the article of shading, when the polaroid polarization scale correspondence of inner ring, outer shroud is consistent, namely the angle of the polarization direction of outer shroud polaroid 6-a, inner ring polaroid 6-b is 0 °, and transmittance is 100%, when rotation inner ring, the angle of the polarization direction of outer shroud polaroid 6-a, inner ring polaroid 6-b increases gradually, and transmittance reduces gradually, when angle becomes 90 °, transmittance is 0%, thus realizes the object of light transmission capacity among equal control inner ring.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
