The sliding groove that sliding block is adapted.
Further, the inner chamber of above-mentioned diaphragm main body is rectangular configuration, and the controllable register includes the first baffle of rectangle
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 fixed using aluminum rivet riveting.
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, illuminates and lighting source is installed in hole.
The beneficial effects of the utility model are：
(1) the utility model uses motor driven rotor, and the eccentric shoe on rotor is arranged on to the cunning of controllable register
In dynamic groove, while rotor rotates, sliding block slides in sliding groove, so as to drive controllable register to be moved in the inner chamber of diaphragm main body
It is dynamic, complete the open and close controlling of light hole.The opening and closing process of diaphragm is directly driven by a motor, and eliminates the drive mechanism of complexity, drop
The low 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 utility model, corresponding to set controllable register
The arc sliding side that there is same radius with sector structure is set to, is matched with the rotary motion of rotor, reduces rotor rotation
Driving resistance when turning, avoids the appearance of Caton phenomenon.
(3) controllable register is arranged to sandwich sandwich by the utility model, can effectively be prevented electromagnetism and various be penetrated
Beta radiation has an impact through controllable register to subsequent optical part.
(4) the utility model can be provided stable by setting illumination hole and lighting source in diaphragm main body for light field
Lighting condition.
