[detailed description of the invention]
Below in conjunction with accompanying drawing and embodiment, the present invention is elaborated:
As it can be seen, a kind of iris aperture device, including body 11 with is connected the shell 14 fixed with body 11。Four axis of guides 35 and the first blade 15 and the second blade 16 it is provided with at body 11 back。First blade 15 and the second blade 16 are correspondingly provided with the first guide rail 31 and the second guide rail 32, the first guide rail 31 and the second guide rail 32 is set on the axis of guide 35 accordingly and along the axis of guide slide。Body 11 is provided with rotation hole 25, rotation hole 25 is provided with rotation bar 12, rotate bar 12 and rotate in rotation hole 25。Bar 12 is respectively equipped with first stirs post 22 and second rotating and stir 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, and described first stirs post 22 and second stirs post 23 and insert accordingly in the first guide hole 33 and the second guide hole 34 and drive two blades to make relative sliding thus controlling the size of aperture。Rotating, bar 12 is additionally provided with driving post 21, also includes and drive the push rod 9 driving post 21 to rotate。
Additionally, component related to the present invention on camera lens fixes cylinder 1 before including, rear fixing cylinder 2, middle boxes 3, iris aperture drives frame 4, motor 5, guide shaft A6, guide shaft B7。
During use, front fixing cylinder 1, rear fixing cylinder 2 and middle boxes 3 collectively constitute part before, during and after optical zoom monitoring camera。Mechanical variable iris apparatus is fixed on above middle boxes 3。Having guide shaft A6 and guide shaft B7 to be fixed on above front fixing cylinder 1 and rear fixing cylinder 2 respectively, iris aperture drives frame 4 to slide on guide shaft A6 and guide shaft B7。Motor 5 drives frame 4 to provide driving force forward or backward for iris aperture。
Iris aperture drives frame 4 in optical zoom monitoring camera, can load eyeglass on the one hand, undertake the function of zoom in whole optical lens。Still further aspect, is had an effect by push rod 9 and mechanical variable iris apparatus, makes aperture bore change。
During use, the first blade 15 is slided by the axis of guide 35 on body 11, and the second blade 16 is slided by the axis of guide 35 on body 11。Rotating bar 12 to be arranged on the rotation hole 25 of body 11 and rotate, the first the first guide hole 33 stirring post 22 and the first blade 15 coordinates, and along with the rotation rotating bar 12, stirs the first blade 15 and slides up and down。Second the second guide hole 34 stirring post 23 and the second blade 16 coordinates, and along with the rotation rotating bar 12, stirs the second blade 16 and slides up and down。First blade 15 builds lower half circle, and the second blade 16 builds upper semi-circle, lower half circular hole and upper half circular hole and is collectively forming light ring through hole, along with they slide up and down, forms the change that the Circular Aperture of mechanical variable iris apparatus is descending, ascending。Spring 13 for resetting is enclosed within above rotation bar 12, makes rotation bar 12 under static state, turns to side all the time, and the Circular Aperture making mechanical variable iris apparatus is maximum。(because the optical system of corresponding optical zoom monitoring camera, when little multiplying power, iris aperture drives frame 4 at front fixing cylinder 1 foremost, and now clear aperature is maximum。) finally worked in coordination by screw hole 29, hole 30, location and the screw hole 27 of body 11, locating dowel 28 with shell 14, rotation bar 12 and spring 13 are wrapped, forms 1 complete system。
Because the effect of iris aperture device, it is simply that under camera lens different multiplying, it is possible to control the size of camera lens light hole。So the relation according to the computed zoom rate out of varifocal optical system Yu stop opening, push rod 9 is produced the shape of curvilinear guide 41。Rotate bar 12, due to the effect of spring 13, drive post 21 can be fitted in above the sliding surface of curvilinear guide 41。Rearmost end is moved to foremost along with what iris aperture drove frame 4 in the past fixing cylinder 1, curvilinear guide 41 can promote driving post 21 to do angle change, namely rotating bar 12 to move in a circle with rotation hole 25, thus driving two pieces of blades adjacent to each other gradually, clear aperature is gradually reduced。When iris aperture drives the rearmost end of frame 4 fixing cylinder 1 in the past to move to foremost, clear aperature is gradually increased。
