Balance mechanism for lens cone

Abstract

The invention discloses a balance mechanism for lens cone, and the balance mechanism for lens cone comprises a fixing base used for fixing and mounting the lens cone of a telescope, two fixing sheets are vertically formed on the upper surface of the fixing base, two fixing sheets are symmetrically formed with interval and the lens cone is formed between two fixing sheets; a balance assembly is formed at the outer side of the fixing sheet, and the balance assembly comprises a first elastic piece, a second elastic piece, a first sliding rail and a second sliding rail, one end of the first elastic piece is fixedly connected to one end of the second elastic piece, the other end of the first elastic piece is connected to the first sliding rail in a sliding mode while the other end of the second elastic piece is connected to the second sliding rail in a sliding mode, the first elastic piece and the second elastic piece can slide along the first sliding rail and the second sliding rail while the lens cone rotates. The balance mechanism for lens cone is reasonable in strdryucture design, the balance and stable state for center of gravity for the lens cone can be guaranteed under any rotating angle of the lens cone, the measurement precision for the telescope and the following shoot to the object can also be guaranteed with good practical value.

Description

technical field [0001] The invention relates to a lens barrel balance mechanism, in particular to a balance mechanism capable of ensuring a stable center of gravity of the lens barrel at any rotation angle of the lens barrel, and belongs to the technical field of astronomical telescope equipment. Background technique [0002] A telescope is a visual optical instrument used to observe distant objects. It can magnify the small opening angle of distant objects by a certain magnification, so that it has a larger opening angle in space, making it impossible to see clearly or clearly with the naked eye. Resolved objects become clearly identifiable. Therefore, the telescope is an indispensable tool in astronomy and ground observation. It is an optical system that keeps the incident parallel light beams parallel to exit through the objective lens and eyepiece, but the existing large telescopes do not have a lens barrel balance mechanism, and the length of the lens barrel is relativ...

AI Technical Summary

Problems solved by technology

It is an optical system that keeps the incident parallel light beams parallel to exit through the objective lens and eyepiece, but the existing large telescopes do not have a lens barrel balance mechanism, and the length of the lens barrel is relatively long. The center of gravity of the telescope will change at any time with the change of the adjustment angle. It is prone to instability when adjusting the focus, and cannot be balanced in time, which will affect the use of the telescope, the accuracy of measurement and the tracking and shooting of the target.
