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 for telescopic system, can be used for the linear detection system of Precise Orbit based on telescopic system technology, belong to photoelectric measurement and field of mechanical technique.
background technology
telescopic system in the market all only has a telescopic system, and a focusing handwheel drives a focusing component, realizes the function of far and near distance focusing.The problem of bringing is like this, if had, sights the demand that two phase close-targets are measured simultaneously, must first sight one and measure, then sight another and measure.As while using the linear detection system of Precise Orbit to detect track deformation, first measuring process must be sighted vertically (or level) scale and measure routinely, 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
in order to address the above problem, the object of the present invention is to provide a kind of ganged focus mechanism for telescopic system.
in order to reach above object, the technical solution used in the present invention is: for the ganged focus mechanism of telescopic system, it comprises housing, be arranged on a plurality of telescopic systems on housing, rotating focusing handwheel, with the burnt gear of the coaxial homophony being connected of focusing handwheel, the burnt tooth bar of homophony being meshed with the burnt gear of homophony, a plurality of pairs of being meshed respectively with the burnt tooth bar of the homophony gears of focusing, each telescopic system comprises focusing component, each focusing component comprises secondary focusing tooth bar, secondary focusing gear is corresponding one by one with secondary focusing tooth bar, and engagement respectively.
further, secondary focusing gear comprises the one-level secondary focusing gear being meshed with the burnt tooth bar of homophony and the secondary focusing of the secondary gear being meshed with pair focusing tooth bar.
further, a plurality of telescopic systems be arranged in parallel, and focusing tooth bar vertically arranges.
the present invention is for the ganged focus mechanism of telescopic system, a plurality of telescopic systems are combined, many group object lens, eyepiece component are assemblied on same housing simultaneously, when measuring, only need to use one of them eyepiece, adjust focusing handwheel, focusing handwheel drives focusing tooth bar to move up and down, and focusing tooth bar drives again a plurality of secondary focusing gears to rotate simultaneously simultaneously, thereby moves when realizing two focusing components, focus clear, realize real ganged focus.Use ganged focus mechanism, only need focusing once, can realize focusing simultaneously, increase work efficiency.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention;
fig. 2 is complete section structural representation of the present invention.
number in the figure is:
1, housing; 2, focusing handwheel; 3, the burnt tooth bar of homophony; 41, the secondary focusing of one-level gear; 42, the secondary focusing of secondary gear; 5, focusing component; 6, eyepiece component; 7, objective lens unit; 8, the burnt gear of homophony; 9, secondary focusing tooth bar.
Embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
from the structural representation of accompanying drawing 1, can find out, the invention provides the ganged focus mechanism for telescopic system, it comprises housing 1, be arranged on a plurality of telescopic systems on housing 1, rotating focusing handwheel 2, the burnt gear 8 of homophony coaxially fixing with focusing handwheel, the burnt tooth bar 3 of homophony being meshed with the burnt gear 8 of homophony, a plurality of pairs of being meshed respectively with the burnt tooth bar 3 of homophony are focused gears, each telescopic system comprises focusing component 5, each focusing component 5 comprises secondary focusing tooth bar 9, secondary focusing gear is corresponding one by one with secondary focusing tooth bar 9, and engagement respectively.
telescopic system also comprises eyepiece component 6 and the objective lens unit 7 being arranged on housing 1.
pair in the present embodiment focusing gear and telescopic system respectively have two, and two telescopic systems are setting up and down and parallel, and focusing tooth bar 3 vertically arranges, corresponding, and a plurality of secondary focusing gears are also setting up and down, and are meshed with the tooth bar 3 of focusing respectively.Secondary focusing gear comprises the one-level secondary focusing gear 1 being meshed with the burnt tooth bar 3 of homophony and the secondary focusing of the secondary gear 2 being meshed with pair focusing tooth bar 9, and the secondary focusing of one-level gear 1 is coaxially fixing with the secondary focusing of secondary gear 2.
when measuring, human eye aims at the eyepiece of upper end or lower end, adjust focusing handwheel 2, focusing handwheel 2 drives the burnt tooth bar 3 of homophony to move up and down, the burnt tooth bar 3 of homophony drives again two secondary focusing gears to rotate simultaneously simultaneously, and then drives the movement of secondary focusing tooth bar 9, thereby moves when realizing two focusing components 5, focus clear, realized real ganged focus.
above embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art understand content of the present invention and implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
