Abstract

The invention discloses a transmission device of a sextant. The transmission device comprises a dial, a micro-motion disk and an indicating arm which is fixedly connected with an axis bracket of the dial. The micro-motion disk is connected with the dial through the indicating arm, and moves in a relatively sliding manner along the outer edge of the dial; a salient strip is arranged at the side edge of the micro-motion disk, and is in relative contact with the surface of a handle assembly fixed on the indicating arm. The micro-motion disk slidably moves on the dial through handles, when the micro-motion disk works, the handles are furled and thus the micro-motion disk can slide on the dial, and when the handles are released, and thus a certain distance can be kept between the micro-motion disk and the dial. The transmission device disclosed by the invention has the advantages of being simple in structure of the whole scheme, concise in working procedures and convenient to use, and saves the labor cost, and improves the work efficiency.

Description

technical field [0001] The invention relates to a navigation surveying instrument device, in particular to a transmission device of a sextant. Background technique [0002] A sextant is an optical instrument used to measure the angle between two distant targets. It is usually used to measure the angle between the sun or other celestial bodies and the sea level or horizon at a certain moment, so as to quickly know the latitude and longitude of the position of the ship or aircraft. Played a major role in navigation. The micro-motion plate is an important degree device on the sextant, and the micro-motion plate is pushed to indicate the scale value on the dial. Such a transmission mechanism is neither time-saving nor labor-saving, and the processing procedure is complicated, which increases the production cost. Contents of the invention [0003] The object of the present invention is to solve the above existing problems and provide a sextant transmission device with simple ...
