Description
Technical Field
The utility model relates to the technical field of optical instrument manufacturing, in particular to a rough and fine focusing mechanism of a target observation mirror.
Background
In the production process of the telescope, due to different focusing requirements, especially the requirements of a plurality of telescope on finer adjustment, a focusing mechanism combining coarse adjustment and fine adjustment is developed by a plurality of enterprises, but the structure is complex, and the operation difficulty is high.
Disclosure of Invention
The utility model aims to provide a coarse and fine focusing mechanism of a target observation mirror, which meets the mutual collection of coarse adjustment and fine adjustment of the target observation mirror through the structural design.
In order to achieve the purpose, the utility model adopts the technical scheme that:
the utility model provides a look rough and fine focusing mechanism of target scope, includes the center pin, outer axle, sleeve pipe, prism, its characterized in that: the outer inside pivot that is hollow of axle, outer inside being provided with rotatable center pin, center pin left end fixed connection fine tuning hand wheel, outer axle left end fixed connection coarse tuning hand wheel, outer off-axial surface is provided with the external screw thread, the intraductal internal thread that is provided with of cover, the sleeve pipe cup joints at outer epaxial and forms the cooperation with the external screw thread, the fixed prism in sleeve pipe lower part, the fixed third gear of center pin right-hand member, the adjustment axle right-hand member is provided with the second gear, the second gear is mutually supported with the third gear, the adjustment axle left end is provided with the fourth gear, outer axle left part is provided with first gear, first gear forms the cooperation with the fourth gear.
Has the advantages that:
this scheme is through the design of hollow outer axle, can install coarse adjusting hand wheel and fine adjustment hand wheel on same axis, rotatable coarse adjusting hand wheel drives outer rotation of shaft, utilize the internal thread of cover intraduct and the external screw thread of outer axle surface to mutually support, thereby it carries out the adjustment of focus to drive the prism production displacement, when needs carry out the fine tuning, rotatory fine adjustment hand wheel drives the center pin rotation, thereby it is rotatory to drive the third gear, because the third gear rotates with the second gear, thereby it rotates to drive the adjustment shaft rotation and consequently drive the fourth gear and rotate, the fourth gear is rotatory to drive first gear and rotate, finally drive outer rotation, owing to adopt multiunit gear to cooperate, can realize the adjustment of different proportions according to the gear combination of difference.
