Optical instrument

Abstract

The invention discloses an optical instrument which comprises a working bottom plate, a fixing rod is arranged in the middle of the left side of the upper end of the working bottom plate, a mounting bottom ring is arranged on the right side of the middle of the upper end of the working bottom plate, a placing disc is arranged at the upper end of the mounting bottom ring, and an anti-exposure refraction judgment failure triggering mechanism is arranged on the periphery of the bottom end of the placing disc. And an anti-exposure refraction failure judgment mechanism is arranged in the middle of the bottom end in the mounting bottom ring. According to the invention, the starting mechanism is triggered by the anti-exposure refraction failure judgment mechanism, and the movable supporting and stabilizing mechanism is triggered by the starting mechanism, so that the stability of the working bottom plate and the optical observation cylinder in the using process is improved, and the conditions of shaking, deviation and toppling caused by external collision in the working and using process are prevented; and the supporting effect can be achieved if toppling occurs, and property loss can be caused if toppling damage occurs.

Description

technical field [0001] The invention relates to the field of optical instruments, in particular to optical instruments. Background technique [0002] At present, optical instruments are composed of single or multiple optical devices. Optical instruments are mainly divided into two categories. One is optical instruments that form real images, such as slide projectors, cameras, etc., and the other is optical instruments that form virtual images, such as Telescopes, microscopes, magnifiers, etc., after the existing optical instruments move up and down the lens barrel, it is easy to make the horizontal position of the lens barrel invalid, and the working personnel cannot find the problem at the first time, and get it when they continue to use it. The data obtained are easily inaccurate, and when the observation objects are placed and observed, they are directly exposed to the outside. If there is an abnormal light, it will lead to exposure and make it impossible to see the speci...

[0002] At present, optical instruments are composed of single or multiple optical devices. Optical instruments are mainly divided into two categories, one is optical instruments that form real images, such as slide projectors, cameras, etc., and the other is optical instruments that form virtual images, such as For telescopes, microscopes, magnifying glasses, etc., after the existing optical instruments move and adjust the lens barrel up and down, it is easy to make the horizontal position of the lens barrel invalid, and the working personnel cannot find the problem at the first time, and they can get it when they continue to use it. The data is not accurate enough, and when the observation objects are placed and observed, they are directly exposed to the outside. If the light is abnormal, it will lead to exposure, and cause the specific situation of the observation objects to be unclear. The environment for storage and use is constant, and sometimes it will be relatively humid. If you stay in this environment for a long time, mold will grow inside the lens barrel, which will easily lead to errors in the final data results
