Abstract
The utility model discloses a vane applied to a stepping aperture, wherein the free end of a vane body extends across a light hole in a gear rotary disc, and when the vane body closes to the center of a aperture hole to close or open the aperture hole, the free end of the vane body is always contacted with the edge of the aperture hole, so that the problem that the vane body is blocked due to cocking deformation in the opening and closing motions is effectively prevented, the vane body is ensured to move smoothly in the stepping aperture, and the vane applied to the stepping aperture has the advantages of simple structure.
Description
[technical field]
The utility model relates to blade, especially a kind of blade for stepping aperture.
[background technology]
Blade in stepping aperture is six, mode with circle is approached to centre, when the complete closed closed gear rotating disk light hole of blade, as shown in Figure 1, blade free end 10 is positioned at gear turntable light hole, between blade, can produce interaction force, and blade itself is very thin, the blade free end 10 meeting perks of stress deformation, and in the structure of camera lens, the space of leaving aperture for is original just very little, the frequent open and close movement of blade, as contacted with eyeglass, easily scratch eyeglass, the blade of distortion also can block gear turntable light hole.
The utility model is researched and proposed for the deficiencies in the prior art.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of blade for stepping aperture, the free end of blade body extends across gear turntable light hole, when blade body, to gear turntable light hole center, draw close and make gear turntable light hole closed or while opening, the free end of blade body rides on gear turntable light hole limit all the time, the problem that effectively prevents blade body from producing distortion perk in opening and closing movement and block, has feature simple in structure.
For solving the problems of the technologies described above, a kind of blade for stepping aperture of the utility model, adopts following technical scheme:
A kind of blade for stepping aperture of the utility model, comprise for blocking the blade body of the gear turntable light hole of gear on turning, described blade body one end be provided with for base on the blade rotation hole that is rotatably assorted of multidiameter, in described blade body, be also provided with for gear turntable on the folding that is slidably matched of the protruding axle of guiding control chute, the described blade body other end is free end, and described free end rides on the limit of gear turntable light hole while rotating all the time.
A kind of blade for stepping aperture of the utility model, the free end of blade body extends across gear turntable light hole, when blade body, to gear turntable light hole center, draw close and make gear turntable light hole closed or while opening, the free end of blade body rides on gear turntable light hole limit all the time, the problem that effectively prevents blade body from producing distortion perk in opening and closing movement and block, guarantee that the activity of stepping aperture Leaf body is smooth and easy, there is feature simple in structure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the structural representation that existing blade body coordinates with the gear turntable light hole of gear turntable.
Fig. 2 is the use constitutional diagram that the utility model blocks gear turntable light hole in stepping aperture.
Fig. 3 is the gear turntable light hole fit structure schematic diagram of the utility model and toothed disc.
[embodiment]
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
A kind of blade for stepping aperture of the utility model, comprise for blocking the blade body 1 of the gear turntable light hole 6 on gear turntable 5, gear turntable light hole 6 waits greatly with diaphragm hole is concentric, described blade body 1 is crescent, described blade body 1 one end be provided with for base 2 on the blade rotation hole 4 that is rotatably assorted of multidiameter 3, in described blade body 1, be also provided with for gear turntable 5 on the folding that is slidably matched of the protruding axle 7 of guiding control chute 8, described blade body 1 other end is free end 9, described free end 9 rides on the limit of gear turntable light hole 6 while rotating all the time, avoid free end 9 distortion to snap in gear turntable light hole 6.
During work, gear turntable 5 rotates, the protruding axle 7 of guiding being positioned on gear turntable 5 rotates together, lead protruding axle 7 along evenly arranging on the circumference of gear turntable light hole 6, multidiameter 3 is also circle distribution on base 2, the circle at place is concentric with gear turntable light hole 6, because the blade rotation hole 4 of blade body 1 one end is rotatably assorted with multidiameter 3, blade body 1 can only be rotated around multidiameter 3, now, folding in blade body 1 is controlled chute 8 under the effect of the protruding axle 7 of guiding, 1 of blade body is corresponding to multidiameter 3 rotations, so that gear turntable light hole 6 is sheltered from, or open gear turntable light hole 6 is exposed.
Claims (2)
1. the blade for stepping aperture, it is characterized in that comprising for blocking the blade body (1) of the gear turntable light hole (6) on gear turntable (5), described blade body (1) one end be provided with for base (2) on the blade rotation hole (4) that is rotatably assorted of multidiameter (3), in described blade body (1), be also provided with for gear turntable (5) on the folding that is slidably matched of the protruding axle of guiding (7) control chute (8), described blade body (1) other end is free end (9), described free end (9) rides on the limit of gear turntable light hole (6) while rotating all the time.
