Abstract
The utility model provides a monocular convenient for focusing. The monocular comprises a lens cone, an eye lens, an object lens, a focusing lens group located between the eye lens and the object lens, a rack which drives the focusing lens group to move and a first gear which is engaged with the rack, wherein the eye lens and the object lens are arranged on the lens cone. The monocular is characterized in that the first gear is engaged with the second gear; a wheel shaft of the second gear passes through the lens cone, is extended outwardly and is connected with two focusing hand wheels which are symmetrically arranged out of the lens cone. Through conveniently toggling the focusing hand wheels, the wheel shaft drives the second gear to rotate. Then, the second gear drives the first gear to rotate and then the rack and the focusing lens group are driven to move so that focusing is completed. A focusing speed and accuracy can be effectively increased so that some high speed objects can be tracked and observed. A suitable scope of a telescope is enlarged. Usage of the monocular is convenient and practical.
Description
Technical field
The utility model relates to a kind of telescope, and particularly a kind of monocular of being convenient to focus belongs to the optical devices technologies field.
Background technology
Telescope is a kind of important optical device, can make people see scenery at a distance clearly by it, is widely used in fields such as tourism, military affairs, Aero-Space.And ordinary populace employed be wherein to carry the most convenient, the simplest small-sized monotubular of structure or binoculars.The gear train that present monocular generally all adopts screw mandrel to cooperate with nut is focused, though this mode is simple in structure, the speed of focusing is relatively slow, in case need to observe pace of change faster during scenery, this telescope just is difficult to adapt to.This will dwindle the range of application of monocular, make troubles to the user.Therefore be necessary prior art is improved.
Summary of the invention
The purpose of this utility model is to provide a kind of monocular of being convenient to focus.
The utility model provides a kind of like this monocular of being convenient to focus, comprise lens barrel, be located at eyepiece and object lens on the lens barrel, focusing lens group between eyepiece and object lens, drive the tooth bar that the focusing lens group moves, first gear that is meshed with tooth bar, it is characterized in that first gear is meshed with second gear, the wheel shaft of second gear passes lens barrel and stretches out, and link to each other with two focusing handwheels that the lens barrel external symmetry is provided with, to make wheel shaft drive second gear to rotate, again by the rotation of second gear driven, first gear by stirring focusing handwheel, and then drive tooth bar and the focusing lens group moves, to finish focusing.
The wheel shaft two ends of described second gear are connected with lens barrel by bearing and seal, and second gear is located on the interior wheel shaft of lens barrel, and two focusing handwheels are located on the outer wheel shaft of lens barrel, conveniently to stir focusing.
The utlity model has following advantage and effect: adopt such scheme, can make wheel shaft drive the rotation of second gear by stirring focusing handwheel easily, rotate by second gear driven, first gear again, and then drive tooth bar and the focusing lens group moves, finishing focusing, thereby effectively improve focusing speed and accuracy, so that some high speed objects of tracing observation, enlarged the telescopical scope of application, made the use of monocular convenient, practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The monocular of being convenient to focus that the utility model provides, comprise lens barrel 1, be located at the eyepiece of lens barrel 1 one ends and the object lens of the other end, focusing lens group 2 between eyepiece and object lens, drive the tooth bar 3 that focusing lens group 2 moves, first gear 7 that is meshed with tooth bar 3, first gear 7 is meshed with second gear 6, the wheel shaft 5 of second gear 6 passes lens barrel 1 and stretches out, and link to each other with two focusing handwheels 4 that lens barrel 1 external symmetry is provided with, wheel shaft 5 two ends of described second gear 6 are connected with lens barrel 1 by bearing and seal, second gear 6 is located on the wheel shaft 5 in the lens barrel 1, two focusing handwheels 4 are located on lens barrel 1 wheel shaft 5 outward, making wheel shaft 5 drive second gear 6 to rotate, drive first gear 7 by second gear 6 again and rotate, and then drive tooth bar 3 and focusing lens group 2 moves by stirring focusing handwheel 4, finish focusing to stir, as Fig. 1.
