Description

Technical Field

[0001] The utility model relates to the technical field of equatorial mounts, in particular to a horizontal latitude connecting rod adjustment mechanism for a large equatorial mount. Background Art

[0002] An equatorial mount is an instrument that rotates with an axis parallel to the Earth's axis of rotation to track the rotation of the sky. It is commonly used in telescopes, satellite dishes and cameras. The advantage of an equatorial mount is that it allows the device connected to it to track any celestial body in the sky that moves with diurnal motion by only driving one axis at a fixed rate.

[0003] When a large equatorial mount is in use, the horizon latitude needs to be adjusted. After the adjustment, there is a lack of a self-locking structure, and it may become loose during the process of tracking celestial bodies in the sky. Therefore, how to design a horizon latitude linkage adjustment mechanism for a large equatorial mount has become a problem that we currently need to solve. Utility Model Content
