Description

Technical Field

[0001] The utility model relates to the technical field of equatorial mount accessories, in particular to a two-in-one locking mechanism for an astronomical telescope used in an equatorial mount. Background Art

[0002] The equatorial mount is the most commonly used astronomical instrument in astronomical observation and photography. It was developed to improve the shortcomings of the horizontal device. Its main purpose is to overcome the influence of the earth's rotation on star observation. A set of standard astronomical telescopes is usually composed of a telescope, an equatorial mount, a tripod and other parts.

[0003] An astronomical telescope is usually connected to an equatorial mount via a dovetail locking mechanism. The equatorial mount is equipped with a dovetail locking mechanism. The lens barrel of the astronomical telescope is generally fixed with a clamp. The clamp is provided with a dovetail seat. During installation, the dovetail seat is inserted into the dovetail groove of the dovetail locking mechanism and tightened. However, the lens barrel of the astronomical telescope currently uses a clamp with two different dovetail seats, namely a V-type dovetail seat and an L-type dovetail seat. When installing these two dovetail seats, the existing dovetail locking mechanism cannot be perfectly adapted, resulting in difficulty in meeting usage requirements.

[0004] Therefore, how to design a two-in-one locking mechanism for an astronomical telescope on an equatorial mount has become a problem that we currently need to solve. Utility Model Content
