Can find out that in sum the focus control of existing focusing telescope and diopter adjustment device minute are arranged, focus control is installed on the axis, the diopter adjustment device is installed on one of them lens barrel, this kind structure is not too convenient when operation, and owing to have limitation on the structure, so that the outward appearance of product can't realize variation.
Summary of the invention
For simplifying traditional telescope right lens-barrel the operation inconvenience that the diopter adjustment device brings is set separately, makes simultaneously whole mirror structure compacter, practical, the utility model provides a kind of telescope compound focusing device.
The utility model provides a kind of like this telescope compound focusing device, comprise the telescope axis, be provided with it in telescope axis lower end with focusing lever and the moving member that links to each other with focusing handwheel, this moving member also with its on band look and transfer looking of bar to transfer nut to link to each other, transfer looking of handwheel to transfer axle to link to each other depending on transferring nut to look with its upper band that places telescope axis upper end by dead man, focusing lever with look the accent bar and link to each other with telescopical focusing lens group by connecting rod respectively.
Described moving member comprises outside disk, the inner cylinder with cavity, is positioned at the groove between disk and cylinder, and wherein, the outer wall of disk and focusing handwheel inwall bolt so that during the rotation focusing handwheel, make disk move up and down along the focusing handwheel inwall; Cylindrical outer wall is transferred the nut inner wall bolt with looking, and looks when transferring nut in order to rotate, and makes to look and transfers nut to move up and down along cylindrical outer wall; Telescope axis lower end is fixed in the cylindrical cavity; The focusing lever lower end is fixed by screws in the groove between disk and cylinder.
Looking of described its inwall and moving member cylindrical outer wall bolt transfers outer wall one side of nut to be provided with groove, opposite side is provided with the post ear, place in the groove depending on the lower end of transferring bar, the upper end of post ear places the axial notch of dead man, in order to rotate together with the post ear when dead man rotates, look with drive and to transfer nut to rotate synchronously, thus make look transfer nut and on look and transfer bar to move up and down along the moving member cylindrical outer wall.
Described dead man is provided with axial notch, place in this axial notch depending on the post ear of transferring nut, the upper end of dead man is annulus, annulus is socketed on the telescope axis outer wall, and connect annulus and look the accent axle by latch, look the accent handwheel depending on transferring the axle upper end to be provided with, look when transferring handwheel in order to rotate, making to look transfers axle, dead man to rotate, simultaneously by dead man stir look transfer nut and on look the accent bar, and move up and down along the moving member cylindrical outer wall with looking connecting rod and the focusing lens group of transferring bar to link to each other, thereby the fine setting of realization binocular diopter difference.
The utlity model has following advantages and effect: adopt such scheme, can be easily by rotate focusing handwheel drive moving member and on focusing lever, and look transfer nut and on look and transfer bar together to move up and down, thereby drive and focusing lever with look connecting rod and the focusing lens group of transferring bar to link to each other and move up and down the adjustment of realization telescope focal length; Again by rotation look transfer handwheel to drive to look transfer axle, dead man, look transfer nut and on look the accent bar, and move up and down with looking connecting rod and the focusing lens group of transferring bar to link to each other, thus the fine setting of realization binocular diopter difference.It is easy to operate, and is simple in structure, has simplified traditional telescope right lens-barrel the operation inconvenience that the diopter adjustment device brings is set separately, simultaneously so that mirror structure is compacter, attractive in appearance on the whole.
