Abstract
The utility model relates to a linkage fast focusing telescope which belongs to the design field of an optical instrument. The utility model comprises a lens barrel, an object lens group, a focusing lens group and a focusing handwheel. The utility model is characterized in that the focusing handwheel is connected with a focusing nut through a screw thread. The focusing nut is connected with a focusing lens seat with the focusing lens group through a focusing driving screw; the front end of the focusing handwheel is simultaneously connected with a vortex blade aperture which is installed by a clamping ring, and the vortex blade aperture is installed on the lens barrel by the clamping ring through the screws. The utility model has the advantage that the focus of the telescope provided by the utility model is designed with two grade positions. At the near distance grade, the different scenes within the range from 0.25 to 2m can be seen clearly without changing the focus; at the remote distance grade, the different scenes within the range from 2m to 8 can also be seen clearly without changing the focus. The linkage fast focusing telescope has the functions of the long depth of field and the linkage fast focusing, which satisfies the operating requirement of the frequent change within the working distance from 0.25m to 8.
Description
Technical field:
The utility model relates to the fast focusing telescope of a kind of coordinated type, belongs to the ray machine design field.
Background technology:
New according to looking into both at home and abroad, telescope all adopts common focusing mode at present, be difficult to satisfy the request for utilization of operating distance frequent changes between 0.25m～∞, when particularly observing closely scenery, the subtle change of viewing distance, image just can produce fuzzy, in order to see the scenery in the variable in distance clearly, constantly focusing continuously, this is very inconvenience in practical operation is used.
Summary of the invention
The technical matters that solves
For fear of the deficiencies in the prior art part, the utility model provides a kind of coordinated type fast focusing telescope, has the long depth of field, the coordinated type function of focusing soon.This telescopical focal length design has two gears to put, and sees the different scenery in 0.25～2m scope under the low coverage shelves can be guaranteed focus state not clearly, does not focus at the long distance shelves and also can see different scenery in 2m～∞ scope clearly.Can solve telescope focuses soon and observes the difficult problem of far and near target, convenient telescopical observation operation.
Technical scheme
The utility model comprises: lens barrel 4, objective lens 6, focusing lens group 11, focusing handwheel 3, it is characterized in that: focusing handwheel 3 links to each other with focusing nut 7 by screw thread, focusing drives screw 8 nut 7 of will focus and connects together with the focusing microscope base 10 that focusing lens group 11 is installed, focusing handwheel 3 front ends link to each other with the blade aperture 2 that relies on pressure ring 1 to install simultaneously, and pressure ring 1 is installed in blade aperture 2 on the lens barrel 4 by screw 8.Regulate focusing handwheel 3 and drive screw 8 by focusing nut 7, focusing and drive focusing microscope base 10 and seesaw with focusing lens, thereby change telescopical observation focal length, focusing handwheel 3 front ends are stirred the size that blade aperture 2 changes light holes simultaneously.
The stopper slot of on lens barrel, offering 9, the microscope base 10 that can prevent to focus rotates, and has limited focusing microscope base 10 and the distance that focusing lens group 11 moves forward and backward simultaneously, is the long distance shelves foremost, and most proximal end is the low coverage shelves.
Beneficial effect
The beneficial effects of the utility model are: the telescopical focal length design that the utility model provides has two gears to put, under the low coverage shelves can be guaranteed focus state not, see the different scenery in 0.25～2m scope clearly, do not focus at the long distance shelves and also can see different scenery in 2m～∞ scope clearly.Have the long depth of field, the coordinated type function of focusing soon, satisfy the request for utilization of operating distance frequent changes between 0.25m～∞.

Embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
The utility model is made up of pressure ring 1, blade aperture 2, focusing handwheel 3, lens barrel 4, objective holder 5, objective lens 6, focusing nut 7, focusing drive screw 8, stopper slot 9, focusing microscope base 10, focusing lens group 11, back-up ring 12, other general extension part 13, spring leaf 14.Focusing handwheel 3 links to each other with focusing nut 7 by screw thread, and focusing drives the focusing microscope base 10 that screw 8 will focus nut 7 and focusing lens group 11 is installed and connects together, and focusing handwheel 3 front ends link to each other with the blade aperture 2 of dependence pressure ring 1 installation simultaneously.Regulate focusing handwheel 3 by focusing nut 7, focusing drives screw 8 drive focusing microscope bases 10 and seesaws with focusing lens group 11, promptly change telescopical observation focal length, the stopper slot of offering on the lens barrel 49 is preventing the microscope base 10 of focusing, when focusing nut 7 rotates in company with focusing handwheel 3, limited the distance that focusing microscope base 10 and focusing lens group 11 move forward and backward simultaneously, when focusing drive screw 8 is positioned at (being the long distance shelves) foremost of stopper slot 9, the optimum viewing distance of telescope is 80 meters, when focusing drive screw 8 was positioned at the rearmost end (being the low coverage shelves) of stopper slot 9, the optimum viewing distance of telescope was 1 meter; Carry out above-mentioned focal length when adjusting, regulate focusing handwheel 3 when adjustment focusing microscope base 10 moves forward and backward with focusing lens group 11, focusing handwheel 3 front ends are stirred the size that the blade aperture 2 that relies on pressure ring 1 to install changes light hole, in low coverage shelves light hole minimum, on the contrary in long distance shelves maximum.The utility model elongates the depth of field to scenery closely according to the pinhole imaging system principle, thereby make at telescope when the low coverage shelves guarantee to see clearly 1 meter scenery, also can under focus state not, see the different scenery in 0.25～2 meter scope clearly, when the long distance shelves are seen 80 meters scenery clearly, not focus and also can see different scenery in 2～200 meters scopes clearly.Spring leaf 14 microscope base 10 of will focusing is pressed on the inwall of lens barrel 4, has eliminated the focusing gap.Back-up ring 12 and lens barrel 4 front end together support focusing handwheels 3; Other general extension part is meant some general lighting apparatus components such as image intensifier, eyepiece group.
