A latitude adjustment mechanism for an equatorial mount

Abstract

The invention discloses a latitude regulating mechanism of an equatorial telescope. The equatorial telescope comprises a supporting seat and an hour angle assembly, wherein the hour angle assembly is mounted on the supporting seat and can rotate round the supporting seat. The latitude regulating mechanism comprises a worm wheel, a worm, a joint, a compression spring, a wrench and a limit screw, wherein the worm wheel penetrates through a slot in the side face of the supporting seat and is fixedly connected with the hour angle assembly, and the worm is horizontally arranged under the worm wheel and meshed with the worm wheel; the joint is fixed arranged at one end of the worm, and the compression spring is arranged on the joint in a sleeving manner; the limit screw penetrates through a through hole in the wrench and is fixedly connected with the tail end of the joint, and the wrench is limited at the tail end of the joint; a tooth-shaped structure hinged with the exterior outline of the joint is arranged in the through hole in the wrench and can slide along the joint. The latitude regulating mechanism can achieve a protection effect after precisely adjusting the latitude of the equatorial telescope, and prevents change of the latitude of the equatorial telescope caused by accidental touch, thus overcoming the defects of the prior art.

Description

technical field [0001] The invention relates to a latitude adjustment mechanism applied to an equatorial mount, which can play a protective role after accurately adjusting the latitude of the equatorial mount and prevent latitude changes caused by false touches, and belongs to the technical fields of astronomy and measurement. Background technique [0002] An equatorial mount is a common instrument for measuring angles. It is usually used in conjunction with astronomical telescopes for astronomical observations, and provides measurement scientific data for astronomical phenomena and astronomical research. Generally speaking, because the equatorial mount must make compound angle adjustments in three-dimensional space, its bracket must have high precision, so that the observation angle of the matching telescope can be accurately adjusted to achieve precise positioning of celestial bodies and real-time track. The existing equatorial mount bracket generally mainly includes a su...

Problems solved by technology

However, the wrench of the manual adjustment part included in this manual latitude adjustment mechanism is easy to rotate due to human error, which will cause the adjusted precise latitude to change. , it affects the effect of astronomical observation; if the user finds a latitude error, he needs to adjust the latitude of the equatorial mount again
