Abstract
The invention discloses a linkage focusing mechanism for telescoping systems. The linkage focusing mechanism comprises a shell body, a plurality of telescoping systems, a focusing hand wheel, a primary focusing gear, a primary focusing rack and a plurality of secondary focusing gears, wherein the telescoping systems are arranged on the shell body, the primary focusing gear is coaxially connected with the focusing hand wheel, the primary focusing rack is engaged with the primary focusing gear, and the secondary focusing gears are respectively engaged with the primary focusing rack; each telescoping system comprises a focusing assembly; each focusing assembly comprises a secondary focusing rack; and the secondary focusing gears and the secondary focusing racks are in one-to-one correspondence and are respectively engaged with each other. With the adoption of the linkage focusing mechanism, the simultaneous focusing of the telescoping systems can be realized by only one-time focusing, and the measuring efficiency can then be increased.
Description
Technical field
the present invention relates to a kind of ganged focus mechanism that is used for telescopic system, can be used for the linear detection system of Precise Orbit based on the telescopic system technology, belong to photoelectric measurement and field of mechanical technique.
Background technology
telescopic system in the market all has only a telescopic system, and a focusing handwheel drives a focusing component, realizes the function of far and near distance focusing.The problem of bringing like this is, sights the demand that two phase close-targets are measured simultaneously if having, and then must sight one earlier and measure, and sights another again and measures.As when using the linear detection system of Precise Orbit to detect track deformation; Must at first sight vertical (or level) scale by the routine measurement process measures; Sight level (or vertically) scale again and measure, the method step is more loaded down with trivial details, causes work efficiency very low.
Summary of the invention
the object of the present invention is to provide a kind of ganged focus mechanism that is used for telescopic system in order to address the above problem.
are in order to reach above purpose; The technical scheme that the present invention adopts is: the ganged focus mechanism that is used for telescopic system; It comprises housing, be arranged on a plurality of telescopic systems on the housing, rotating focusing handwheel, with the burnt gear of the coaxial homophony that links to each other of focusing handwheel, the burnt tooth bar of homophony that is meshed with the burnt gear of homophony, with a plurality of pairs that the burnt tooth bar of homophony is meshed respectively gears of focusing; Each telescopic system comprises focusing component; Each focusing component comprises secondary focusing tooth bar, and secondary focusing gear is corresponding one by one with secondary focusing tooth bar, and engagement respectively.
further, secondary focusing gear comprises one-level secondary focusing gear that is meshed with the burnt tooth bar of homophony and the secondary focusing of the secondary gear that is meshed with pair focusing tooth bar.
Further, a plurality of telescopic systems laterally arrange
, and the focusing tooth bar vertically is provided with.
the present invention is used for the ganged focus mechanism of telescopic system, and a plurality of telescopic systems are combined, and organizes object lens, eyepiece component more and is assemblied in simultaneously on the same housing; When measuring, only need to use one of them eyepiece, the adjustment focusing handwheel; Focusing handwheel drives the focusing tooth bar and moves up and down, and the focusing tooth bar drives a plurality of secondary focusing gears again simultaneously and rotates simultaneously, thereby moves when realizing two focusing components; It is clear to focus, and realizes real ganged focus.Use ganged focus mechanism, only need focusing once, can realize focusing simultaneously, increase work efficiency.

telescopic system also comprises the eyepiece component 6 and objective lens unit 7 that is installed on the housing 1.
Pair focusing gear and telescopic system in
present embodiment respectively have two; Two telescopic systems are provided with up and down and parallel, and focusing tooth bar 3 vertically is provided with, and is corresponding; A plurality of secondary focusing gears also are provided with up and down, and are meshed with focusing tooth bar 3 respectively.Secondary focusing gear comprises one-level secondary focusing gear 1 that is meshed with the burnt tooth bar 3 of homophony and the secondary focusing of the secondary gear 2 that is meshed with pair focusing tooth bar 9, and the secondary focusing of one-level gear 1 is coaxial fixing with the secondary focusing of secondary gear 2.
when measuring, the eyepiece of human eye aiming upper end or lower end is adjusted focusing handwheel 2; Focusing handwheel 2 drives the burnt tooth bar 3 of homophony and moves up and down; The burnt tooth bar 3 of homophony drives two secondary focusing gears again simultaneously and rotates simultaneously, and then drives moving of secondary focusing tooth bar 9, thereby moves when realizing two focusing components 5; It is clear to focus, and has realized real ganged focus.
above embodiment only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the people that is familiar with this technology understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
