Description

Technical Field

[0001] The present invention belongs to the technical field of telescope focusing, and specifically relates to a focusing mechanism for an automatic telescope. Background Art

[0002] A telescope is an optical instrument used to observe distant objects. By collecting light and magnifying the image, distant objects can be made to appear clearer and brighter. It is widely used in astronomical observations, ground observations, photography, military, navigation and other fields.

[0003] Many existing telescopes complete the adjustment of the telescope's focal length through manual focusing. When manually focusing, if the focusing base screws are too tight, or the focusing components are loose or have uneven friction, applying an external force will cause a slight displacement of the telescope body, which will in turn cause image drift; moreover, if the force is too strong or the movement is uneven during manual focusing, it may cause the entire telescope to shake, resulting in image drift and affecting the focusing effect. Therefore, we propose a focusing mechanism for an automatic telescope. Summary of the Invention

[0004] The purpose of the present invention is to provide a focusing mechanism for an automatic telescope in order to improve the focusing effect of the telescope body during use.

[0005] The technical solution adopted by the present invention is as follows: A focusing mechanism for an automatic telescope includes a telescope body. A camera fixing base is installed on the right side surface of the telescope body. The upper surface of the left end of the camera fixing base is fixedly connected to a focusing drive bracket. The outer surface of the right end of the telescope body close to the camera fixing base is fixedly connected to a focusing fixing base. A focusing motor is fixedly connected to the upper surface of the focusing fixing base. A focusing motor telescopic rod is installed on the right side surface of the focusing motor. One end of the focusing motor telescopic rod away from the focusing motor is connected to the focusing drive bracket; Two fixing base positioning columns at a certain angle are arranged inside the camera fixing base. An iron sheet is fixedly installed on the upper surface of the focusing fixing base, and the iron sheet is located between the two fixing base positioning columns. A magnet is fixedly connected to the inner surface of the camera fixing base close to the iron sheet.

[0006] In a preferred embodiment of the invention, an objective lens is installed on the left side surface of the telescope body.

[0007] In a preferred embodiment of the invention, the objective lens is connected to the telescope body by means of a threaded connection.

[0008] In a preferred embodiment of the invention, a camera sensor is arranged on the right side surface of the camera fixing base.

[0009] In a preferred embodiment of the invention, the camera sensor is fixedly connected to the right side of the camera fixing base by screws.

[0010] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: 1. In the present invention, two fixing base positioning columns at a certain angle are arranged inside the camera fixing base. The iron sheet is fixedly installed on the focusing fixing base and is located between the two fixing base positioning columns. Under the suction force of the magnet attracting the iron sheet, the camera fixing base closely adheres to the telescope body and maintains gapless sliding, avoiding image drift during the focusing process. Through the cooperation of the above structures, the focusing effect of the telescope body during use can be improved.

[0011] 2. In the present invention, the focusing motor drives the focusing motor telescopic rod to move to the right. The focusing motor telescopic rod is fixedly connected to the focusing drive bracket, the focusing drive bracket is fixedly connected to the camera fixing base, and the camera sensor is also connected to the camera fixing base by screws.
