With the second baffle of rectangle, aperture is provided with second baffle;The sliding block includes the first sliding block and the second sliding block, wherein the
One sliding block is located in the sliding groove of first baffle, and the second sliding block is located in the sliding groove of second baffle.
Further, the inner chamber of above-mentioned diaphragm main body is sector shape structure, and two opposite flanks of the controllable register are
With the arcuate flanks of sector shape structure inner chamber sliding contact.
Further, above-mentioned controllable register is sandwich sandwich, and intermediate layer is stereotype, and two layers is steel plate in addition;Three
Deck panels are riveted using aluminum rivet and fixed.
Further, above-mentioned sliding block is the sliding block of cylindrical protrusions structure, and the sliding groove is the slip of kidney-shaped pore structure
Groove.
Further, illumination hole is additionally provided with above-mentioned diaphragm main body, illumination installs lighting source in hole.
The beneficial effects of the present invention are:
(1) present invention uses motor driven rotor, and the eccentric shoe on rotor is arranged on to the sliding groove of controllable register
Interior, while rotor is rotated, sliding block is slided in sliding groove, so that drive controllable register to be moved in the inner chamber of diaphragm main body,
Complete the open and close controlling of light hole.The opening and closing process of diaphragm is directly driven by a motor, and is eliminated the drive mechanism of complexity, is reduced
The production and processing cost of electronic diaphragm simultaneously improves diaphragm regulation stability.
(2) inner chamber of diaphragm main body could be arranged to sector shape structure in the present invention, corresponding to be set to controllable register
There is the arc sliding side of same radius with sector structure, matched with the rotary motion of rotor, when reducing rotor rotation
Driving resistance, it is to avoid the appearance of Caton phenomenon.
(3) controllable register is set to sandwich sandwich by the present invention, can effectively prevent electromagnetism and various ray spokes
It is shot through overregulating baffle plate and producing influence to subsequent optical part.
(4) present invention can provide stable photograph by setting illumination hole and lighting source in diaphragm main body for light field
Bright condition.
