Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1~3, in the utility model embodiment, a kind of novel multiple thread is driven zoom structure, including C-
MOUNT1, focusing position-limitting pin 2, guide cylinder 3, focusing drum 4, M2 fastening screws 5, diaphragm adjustment barrel 6, diaphragm position-limitting pin 7, consolidate
Safety barrel 8, optics group 1, group's position-limitting pin 10, optics group 2 11, diaphragm rotary cylinder 12, optics group limit trim ring 13
With annular knurl fixed screw 14, main body composition is divided into two part of optics group transmission component and focusing limit assembly.Focusing component with
Main cylinder optics group element is driven by multiple thread, and structure may be implemented between high low power and stretch, diaphragm is adjusted not by shadow
It rings, the start together with main cylinder running part, carry out diaphragm adjusting more simply and easily, diaphragm adjustment barrel 6 is equal with focusing drum 4
It limits and assembles for pin, the optics group 1 and optics group 2 11 are assembled with installation position-limitting pin 10, and group's diaphragm cylinder is dialled
Bar is easier to be aligned with main cylinder limiting slot, and the diaphragm rotary cylinder 12 rotates diaphragm and stirs diaphragm lobe plate work than traditional pin
It is dynamic.
Specifically, this structure is novel multi-bit screw-thread fit, shaking volume can control within 0.03mm, auxiliary and mating surface
Start together can effectively control start diastema, have apparent anti seismic efficiency, after focusing in different use environments,
Be not in defocusing phenomenon, the entire picture that is imaged is more stable, there is obvious advantage in the reliability of camera lens.
Specifically, the high low power zoom of this structure is realized by stretching lock, start range and angle（Surpass 300 °）Bigger is low
Camera lens height becomes smaller when multiplying power, subrange internal segment save space, is conducive to client machine miniaturization.
Specifically, this structure separates start, one ring of component structure due to being only divided into focusing transmission and two part of diaphragm adjustment
A ring is detained, more saves space than conventional lenses, camera lens is wider using field than conventional lenses overall volume smaller.
Specifically, this structure is used since main cylinder is as driving member, rather than separately as fixing piece, and without using set
Cylinder, the component that the traditional structures such as screw must use, therefore it is more cost-effective.
Specifically, this structure camera lens is under the premise of ensureing stability, dismantling is more convenient, and packaging efficiency is opposite with tradition
CAM start lens assemblings are more efficient（Component is less, is fixed without point screw thread glue between cooperation component）.
Specifically, since diaphragm adjustment barrel and focusing drum are that pin limit assembles, diaphragm contraposition and multiplying power scale pair
Position is not allowed to tend to have deviation, can preferably avoid the error between design value in this way, make client more preferable, more easily use.
Specifically, optics group is assembled with installation position-limitting pin 10, group's diaphragm cylinder driving lever is easier and main cylinder limiting slot
Alignment, assembling is more convenient, more time saving.
Specifically, the rotation of diaphragm rotary cylinder 12 diaphragm stirs diaphragm lobe plate than traditional pin and makees dynamic stability more
It is good, in this way can to avoid diaphragm driving cam plate in assembling process due to uneven or since sheet metal part thickness is inadequate to center
Caused by deform.
