Abstract
The utility model discloses a camera lens diaphragm adjusting mechanism. The camera lens diaphragm adjusting mechanism comprises a diaphragm blade assembly, a rear lens assembly and a diaphragm ring, wherein the rear lens assembly sleeves and covers the diaphragm blade assembly, and the diaphragm ring sleeves the rear lens assembly. The camera lens diaphragm adjusting mechanism further comprises a diaphragm shifting rod; the diaphragm shifting rod is connected with the diaphragm ring; the rear lens assembly is provided with a notch structure; a port of the diaphragm shifting rod is provided with a diaphragm shifting rod notch; the diaphragm blade assembly is provided with a protruding shifting sheet; and the diaphragm shifting rod notch on the diaphragm shifting rod is inserted in the protruding shifting sheet of the diaphragm blade assembly through the notch on the rear lens assembly. According to the camera lens diaphragm adjusting mechanism of the utility model, the diaphragm ring can rotate, so that the shifting rod can be driven to perform manual adjustment on the opening degree of diaphragm blades, and therefore, manual adjustment of a diaphragm can be realized, and the whole product can satisfy requirements of a camera lens, and customers will like the product.
Description
Technical field
The utility model relates to a kind of camera and camera lens, is specifically related to a kind of camera lens aperture governor motion.
Background technology
Camera lens is most important parts in camera, because its quality directly has influence on the quality of taking imaging.Single lens reflex camera.The original design of the reflective mirror of this class camera and prism makes cameraman can from view finder, observe directly the image by camera lens.The camera lens that light sees through camera arrives after reflective mirror, is refracted to focusing screen above and forms image, sees through eye lens and pentaprism, and cameraman can see the scenery of outside in picture window.During shooting, when pressing shutter key, reflective mirror just can up be upspring, shutter curtain above is just opened simultaneously, light (image) by camera lens just projects to and on photosensitive-member, makes its sensitization, and just immediate recovery original state of reflective mirror, can see image in picture window again thereafter.In camera lens, to regulate be all that camera lens automatically adjusts by means such as motor driven gears for most apertures, due to two fields of camera lens and camera lens require differently, in camera lens, needing aperture adjusting is manual adjustments.
Utility model content
The utility model has overcome the deficiencies in the prior art, provides solution camera to drive driving lever aperture blades open degree to be carried out to the camera lens aperture governor motion of manual adjustments problem by the rotation of aperture ring.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
A camera lens aperture governor motion, comprises aperture blades group, rear mirror group, aperture ring, and described rear mirror group upper shield is in described aperture blades group; Described aperture ring is socketed in described rear mirror group; Also comprise aperture driving lever; Described aperture driving lever is connected with described aperture ring; In described rear mirror group, be provided with a gap structure; On described aperture driving lever one port, be provided with aperture driving lever breach, bossed plectrum is set in aperture blades group, the aperture driving lever breach on described aperture driving lever is plugged on the plectrum of aperture blades group projection by breach in rear mirror group; Realization drives driving lever to carry out manual adjustments to aperture blades open degree by the rotation of aperture ring.
Further technical scheme is that in rear mirror group, breach is sector structure breach, and sector notch meets the architectural feature of camera lens, and structure is more stable.
Compared with prior art, the beneficial effects of the utility model are: the utility model drives driving lever to carry out manual adjustments to aperture blades open degree by the rotation of aperture ring, realized the object of aperture manual adjustments, make whole product meet the requirement of camera lens, thereby reached users' favor.
Accompanying drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of an embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, an embodiment of the present utility model be take the 70-200 of Canon model camera and is transformed into the camera lens aperture governor motion that aperture manual adjustments is example, and Fig. 1 is the present embodiment exploded view, and wherein aperture blades group and rear mirror group are that exploded view is illustrated out.Comprise aperture blades group 1, rear mirror group 2, aperture ring 3, rear mirror group 2 upper shields are in aperture blades group 1; Aperture ring 4 is socketed in rear mirror group; Aperture governor motion also comprises aperture driving lever 3; Aperture driving lever is connected with aperture ring; As preferred embodiment, in rear mirror group, be provided with a gap structure; Can pass for aperture driving lever, be provided with aperture driving lever breach on aperture driving lever one port, bossed plectrum is set in aperture blades group, the aperture driving lever breach on aperture driving lever is plugged on the plectrum of aperture blades group projection by breach in rear mirror group; Realization drives driving lever to carry out manual adjustments to aperture blades open degree by the rotation of aperture ring.
Specific embodiment is that aperture blades group, in mirror interior portion, is milled out a fan-shaped breach with milling machine in rear mirror group, and aperture driving lever 3 can directly be contacted with aperture blades group 1.The plectrum 5 that has individual projection in aperture blades group, plectrum rotates just can regulate aperture open degree.Thereby the breach of aperture driving lever 3 inserts the rotation by aperture ring 3 in plectrum drives plectrum to drive aperture blades group to rotate, and realizes the object of aperture manual adjustments.
" embodiment " that spoken of in this manual, " another embodiment ", " embodiment ", etc., refer to specific features, structure or the feature in conjunction with this embodiment, described and be included at least one embodiment that the application's generality describes.In instructions, a plurality of local appearance statement of the same race is not necessarily to refer to same embodiment.Furthermore, while describing a specific features, structure or feature in conjunction with any embodiment, what advocate is in conjunction with other embodiment, to realize this feature, structure or feature also to drop in scope of the present utility model.
Although a plurality of explanatory embodiment with reference to utility model is described the utility model here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and within embodiment will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to the building block of subject combination layout and/or layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
Claims (2)
1. a camera lens aperture governor motion, comprises aperture blades group, rear mirror group, aperture ring, and described rear mirror group upper shield is in described aperture blades group; Described aperture ring is socketed in described rear mirror group; It is characterized in that: also comprise aperture driving lever; Described aperture driving lever is connected with described aperture ring; In described rear mirror group, be provided with a gap structure; On described aperture driving lever one port, be provided with aperture driving lever breach, bossed plectrum is set in aperture blades group, the aperture driving lever breach on described aperture driving lever is plugged on the plectrum of aperture blades group projection by breach in rear mirror group.
