[embodiment]
Below in conjunction with accompanying drawing and embodiment, the present invention is elaborated:
As shown in the figure, a kind of iris ring device, comprises body 11 and the shell 14 being connected and fixed with body 11.At body 11 backs, be provided with four axis of guides 35 and the first blade 15 and the second blade 16.Correspondingly on the first blade 15 and the second blade 16 be provided with the first guide rail 31 and be set in the axis of guide 35 on and along the axis of guide corresponding with the second guide rail 32 of the second guide rail 32, the first guide rails 31 slided.On body 11, be provided with rotation hole 25, be provided with dwang 12 in rotation hole 25, dwang 12 rotates in rotation hole 25.On dwang 12, being respectively equipped with first stirs post 22 and second and stirs post 23, end on the first blade 15 and the second blade 16 is respectively equipped with the first guide hole 33 and the second guide hole 34, thereby described first stirs post 22 and second and stir in corresponding insertion the first guide hole 33 of post 23 and the second guide hole 34 and drive two blades to make the size that relative sliding is controlled aperture.On dwang 12, be also provided with drive post 21, also include the push rod 9 that drives drive post 21 to rotate.
In addition, on camera lens component related to the present invention include before stationary magazine creel 1, rear stationary magazine creel 2, middle boxes 3, iris ring drives frame 4, motor 5, guide shaft A6, guide shaft B7.
During use, part before, during and after front stationary magazine creel 1, rear stationary magazine creel 2 and the common composition optical zoom of middle boxes 3 monitoring camera.Mechanical variable iris apparatus is fixed on above middle boxes 3.Have respectively guide shaft A6 and guide shaft B7 to be fixed on front stationary magazine creel 1 and above rear stationary magazine creel 2, iris ring drives frame 4 to slide on guide shaft A6 and guide shaft B7.Motor 5 provides driving force forward or backward for iris ring drives frame 4.
Iris ring drives frame 4 in optical zoom monitoring camera, can load eyeglass on the one hand, bears the function of zoom in whole optical lens.In addition on the one hand, by push rod 9 and mechanical variable iris apparatus, have an effect, aperture bore is changed.
During use, the first blade 15 slides by the axis of guide 35 on body 11, and the second blade 16 slides by the axis of guide 35 on body 11.Dwang 12 is arranged on the rotation hole 25 of body 11 and rotates, and first the first guide hole 33 of stirring post 22 and the first blade 15 coordinates, and along with the rotation of dwang 12, stirs the first blade 15 and slides up and down.Second the second guide hole 34 of stirring post 23 and the second blade 16 coordinates, and along with the rotation of dwang 12, stirs the second blade 16 and slides up and down.The first blade 15 builds lower half circle, and the second blade 16 builds upper semi-circle, and second circular hole and first circular hole form aperture through hole jointly, along with they slide up and down, form descending, the ascending variation of Circular Aperture of mechanical variable iris apparatus.For the spring 13 resetting, be enclosed within above dwang 12, make dwang 12 under static state, turn to all the time a side, make the Circular Aperture of mechanical variable iris apparatus for maximum.(because the optical system of corresponding optical zoom monitoring camera, in little multiplying power, iris ring drives frame 4 at front stationary magazine creel 1 foremost, and now clear aperature is maximum.) finally with shell 14, by screw hole 27, the reference column 28 of screw hole 29, pilot hole 30 and body 11, work in coordination, dwang 12 and spring 13 are wrapped, form 1 complete system.
Because the effect of iris ring device, is exactly under camera lens different multiplying, can control the size of camera lens light hole.So the zoom rate of calculating according to varifocal optical system and the relation of stop opening are produced the shape of curvilinear guide 41 on push rod 9.Dwang 12, due to the effect of spring 13, drive post 21 can be fitted in above the slipping plane of curvilinear guide 41.Along with iris ring drive frame 4 in the past stationary magazine creel 1 move to foremost rearmost end, curvilinear guide 41 can promote drive post 21 and do angle variation, be that dwang 12 moves in a circle with rotation hole 25, thereby drive two pieces of blades adjacent to each other gradually, clear aperature is dwindled gradually.When iris ring drives the rearmost end of 4 the past of frame stationary magazine creel 1, move to foremost, clear aperature increases gradually.
