Abstract
This utility model relates to a kind of machinery diaphragm, and including control light housing, the side that described control light housing is remotely located from light source is disposed with motor support handle and one group of light modulation sheet support shank from top to bottom, and the end of described motor support handle connects motor；Also include one group of light modulation sheet.Each light modulation sheet in this utility model is adjusted by tuning motor, tunes electric machine rotation, so that it may by flexible cord strength, it is achieved light modulation sheet Angle ambiguity；At least significant end, control light housing is provided with a threading opening, connects coiling mouth and the light modulation sheet of lowermost end with a low force spring, is used for making each strength flexible cord exceptionally straight, and the angle of light modulation sheet then keeps consistent.Motor, when tuning anglec of rotation θ, has just tuned light modulation sheet angle, thus has changed extraneous light intake, used such device, just can realize intensity control by motor easily.
Description
Technical field
This utility model relates to intensity control field, is specifically related to a kind of machinery diaphragm.
Background technology
Application to light source often needs the light intensity parameter of light source luminescent is adjusted, particularly use in experiment
In Tu.But existing light intensity regulating is to be realized, not over mechanical system by some parameters changing component mostly
Carry out controlling the device of light.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of machinery diaphragm.
This utility model is that the technical scheme solving the proposition of above-mentioned technical problem is: a kind of machinery diaphragm, including control
Light housing, the side that described control light housing is remotely located from light source is disposed with motor support handle from top to bottom and one group of light modulation sheet props up
Support handle, the end of described motor support handle connects motor；
Also include that one group of light modulation sheet, one end of described every light modulation sheet are respectively hinged to every described light modulation sheet support shank
End, the other end of described light modulation sheet is freely；
Being provided with wheel disc on the power output shaft of described motor, described wheel disc connects draught line, the end of described draught line
End sequentially passes through every described light modulation sheet from top to bottom and is connected with light modulation sheet every described；
It is connected between the light modulation sheet and control light housing of bottom and has extension spring.
Further, draught line is transparent polyethylene line.
Further, described extension spring is moccasin spring.
The beneficial effects of the utility model are:
Each light modulation sheet in this utility model is adjusted by tuning motor, tunes electric machine rotation, so that it may by flexible cord power
Amount, it is achieved light modulation sheet Angle ambiguity；At least significant end, control light housing is provided with a threading opening, connects coiling with a low force spring
Mouth and the light modulation sheet of lowermost end, be used for making each strength flexible cord exceptionally straight, and the angle of light modulation sheet then keeps consistent.Motor rotates in tuning
During angle, θ, just tune light modulation sheet angle, thus changed extraneous light intake, used such device, just can lead to easily
Cross motor and realize intensity control.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings machinery diaphragm of the present utility model is described further.
Fig. 1 is the structural representation of machinery diaphragm in this utility model.
Detailed description of the invention
Embodiment
According to Fig. 1, the mechanical diaphragm in this utility model, including control light housing 1.
Control light housing 1 is remotely located from the side of light source and is disposed with motor support handle 2 from top to bottom and one group of light modulation sheet props up
Support handle 3, the end of motor support handle 2 connects motor 4.
Also including one group of light modulation sheet 5, one end of every light modulation sheet 5 is respectively hinged to the end of every light modulation sheet 5 support shank 3
Portion, the other end of light modulation sheet 5 is freely.
Being provided with wheel disc on the power output shaft of motor 4, wheel disc connects draught line 6, and the end of draught line 6 is from top to bottom
Sequentially pass through every light modulation sheet 5 and be connected with every light modulation sheet 5；
It is connected between the light modulation sheet 5 and control light housing 1 of bottom and has extension spring 7.
Can be as preferably: draught line 6 is transparent polyethylene line.
Can be as preferably: extension spring 7 is moccasin spring.
The above-described embodiment that is not limited to of the present utility model, the technical scheme of each embodiment above-mentioned of the present utility model that
This can form new technical scheme with combined crosswise, and the technical scheme that the most all employing equivalents are formed all falls within this practicality
In the protection domain of novel requirement.
