Equatorial telescope mechanism capable of stably bearing loads

Abstract

The invention relates to an equatorial telescope mechanism capable of stably bearing loads. The equatorial telescope mechanism comprises a latitude base, an hour angle base, a deflection angle base, aright ascension shaft and a balance weight. The latitude seat comprises a seat body, the two sides of the base body are vertically connected with the side plates correspondingly, and arc-shaped sliding grooves are respectively formed at the inner side. The two sides of the hour angle base are connected with sliding rails respectively, arc-shaped protrusions are arranged on the two sliding rails respectively, correspond to each other in a one-to-one correspondence manner, are arranged in the sliding grooves, penetrate through the two ends of the sliding grooves and are in slip and cooperativeconnection with the sliding grooves. One upper end of the hour angle base extends to form a columnar protrusion, and the other upper end is fixedly connected with right ascension shaft. The columnar protrusion is coaxial with the right ascension shaft, the two lower ends of the deflection angle base are rotationally installed on the columnar protrusion and the right ascension shafts through bearings respectively, and the balance weight is connected with the deflection angle base through a balance weight rod. According to the equatorial telescope mechanism, a G-shaped structure is formed, the borne weight is located at the two ends of the mechanism, equivalently, the weight of all the loads is divided into two parts, the two ends bear half respectively, and therefore the equatorial telescope mechanism is higher in bearing capacity and is more stable.

Description

technical field [0001] The invention relates to an equatorial mount, in particular to a stable load-bearing equatorial mount mechanism. Background technique [0002] The previous stable load-bearing equatorial mount mechanism, such as patent: CN201710637187.X A stable load-bearing equatorial mount mechanism, which adopts a traditional T-shaped mechanism to press all the load weights on the middle point of the right ascension axis to make the right ascension axis more stable. Deformation easily occurs. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention proposes a G-type stable and load-bearing equatorial mount mechanism. [0004] Technical scheme of the present invention: [0005] A stable load-bearing equatorial mount mechanism comprises a latitude base, an hour angle base, a declination base, a right ascension axis and a counterweight; the latitude base comprises a base body, and two sides of the base body are respectively vert...
