Abstract
The utility model discloses an automatic zooming device for a telescope. The automatic zooming device comprises an astronomical telescope (1) and a limiting switch focusing travel limiting mechanism, wherein the astronomical telescope is provided with a manual zooming mechanism; an ocular lens group (2), an object lens group (3), a lead screw (4) and a lead screw nut (5) are arranged in the lens (1); the outer end of the lead screw (4) is connected with a driving mechanism; the switch focusing travel limiting mechanism comprises limiting switches (6) which are arranged at two ends in the lens cone (1) and close to the limit position of the ocular lens group (2) respectively; and a chock block (7) is arranged on a lead screw nut (4) which moves synchronously with the ocular lens group (2). The automatic zooming device is characterized in that a protective sleeve (8) made of an elastic material is wrapped outside the chock block (7). Due to the adoption of the automatic zooming device for the telescope, the chock block can be prevented from being broken, and normal use is ensured.
Description
Technical field
The utility model relates to the optical instrument technical field, specifically is a kind of telescope Automatic zoom lens focusing device.
Background technology
A kind of telescope Automatic zoom lens focusing device is arranged at present, comprise an astronomical telescope camera lens with manual focusing mechanism, be provided with the speed gear follower on the manual focusing knob axle outside described camera lens, this follower is meshed with the driving wheel of the speed gear that is driven by micromotor.By the rotating of micromotor, drive screw mandrel and be fixed on eyepiece group to-and-fro movement on the feed screw nut, realize zoom function.Also be provided with limit switch focusing stroke limiter: a limit switch is respectively established in the moving near limit position of two ends eyepiece group in lens barrel, on the feed screw nut who is synchronized with the movement with the eyepiece group block is housed.When the eyepiece group moved to the near limit position, block touched limit switch, the stop motion of eyepiece group.This device can be easily with only manually the conventional telescope of zoom be adapted as long focal telescopic mirror with autozoom function, greatly reduce equipment cost.
But the telescope Automatic zoom lens focusing device of above structure still has the following disadvantages: the block of eyepiece group bottom is offseting when spacing with two limit switches, block and limit switch have collision, so long-term use may cause the block fracture, thereby telescope can't normally be used.
The utility model content
The technical problems to be solved in the utility model is the anti-stop block fracture of a kind of energy to be provided, to guarantee the normal telescope Automatic zoom lens focusing device that uses.
The technical solution of the utility model is, a kind of telescope Automatic zoom lens focusing device with following structure is provided, and comprises an astronomical telescope camera lens and a limit switch focusing stroke limiter with manual focusing mechanism; Be provided with eyepiece group, objective lens, screw mandrel and feed screw nut in the described camera lens; The outer end of described screw mandrel is connected with driving mechanism; described switch-focus stroke limiter comprise be located in the lens barrel respectively, a limit switch of eyepiece group near limit position, two ends; on the feed screw nut who is synchronized with the movement with the eyepiece group block is housed, described block external packets is wrapped with the protective sleeve of being made by resilient material.
Described driving mechanism comprises micromotor, driving wheel, engaged wheel, and described driving wheel is installed on the output shaft of micromotor, and described engaged wheel rotates synchronously by synchronous band and driving wheel, and described engaged wheel is installed in the outer end of screw mandrel.
After adopting said structure; the utility model telescope Automatic zoom lens focusing device compared with prior art; have the following advantages: because described block external packets is wrapped with the protective sleeve of being made by resilient material; offseting when spacing with two limit switches like this; protective sleeve is avoided directly and the limit switch collision link stopper; the resilient protection cover can play the effect of protection link stopper, avoids long-term the use to cause the block fracture, thereby guarantees telescope is normally used.
