Problems solved by technology
The focus of existing telescope photography is usually achieved by turning the rotating parts on the telescope to adjust the distance between the eyepiece and the objective lens. After the focusing is completed, people will accidentally touch the rotating parts when they touch the rotating parts. Turning causes focal length to change, requiring refocusing

Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0017] refer to Figure 1-2 , a focusing mechanism for telescope photography, comprising a fixed tube 1 arranged horizontally, the bottom of the fixed tube 1 is rotatably connected to a connecting tube 3, and the inner ring of one end of the connecting tube 3 protruding from the bottom of the fixed tube 1 is slidably sleeved with a movable shaft 4. The inner ring of one end of the shaft 4 extending into the connecting pipe 3 is welded with a second pole 7 perpendicular to the movable shaft 4, and the end of the movable shaft 4 extending into the connecting pipe 3 is welded with a second gear tooth, and the movable shaft 4 extends out of the connecting pipe 3 One end ...

The invention discloses a telescope photographing focusing mechanism. The mechanism comprises a fixed pipe arranged horizontally, wherein a connecting pipe is rotationally connected to the bottom of the fixed pipe, a movable shaft is arranged in an inner ring at one end of the connecting pipe in a sliding and sleeved mode, a rotary rod is fixedly installed at one end of the movable shaft, two groups of symmetrical threaded columns are rotationally connected to the two sides of the rotary rod respectively, a rotary shaft is arranged in an inner ring at one end of the connecting pipe in a fixedand sleeved mode, a first bevel gear is arranged on an outer ring at the end, extending out of the connecting pipe, of the rotary shaft in a fixed and sleeving mode, a second bevel gear is arranged atone side of the first bevel gear, a screw is arranged in an inner ring of the second bevel gear in a fixed and sleeved mode, a sliding block is rotationally connected to an outer ring of the screw, and an eyepiece pipe is fixedly connected to one side of the sliding block. By rotating the movable shaft, changing of the distance between an eyepiece set and an objective lens is realized, and telescope photographing focusing is realized; and by limiting the rotation of the rotary shaft, the situation that the distance between the eyepiece set and the objective lens is changed again after focusing is completed, and consequently focusing is ineffective is prevented, and it is guaranteed that the distance between the eyepiece set and the objective lens is fixed after focusing is completed.
Description
technical field [0001] The invention relates to the technical field of focusing mechanisms, in particular to a telescopic photography focusing mechanism. Background technique [0002] A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. It uses the light refracted through the lens or reflected by the concave mirror to make it enter a small hole and converge into an image, and then it is seen through a magnifying eyepiece. . The first function of the telescope is to enlarge the opening angle of distant objects, so that the human eye can see details with smaller angular distances. The second function of the telescope is to send the light beam collected by the objective lens that is much thicker than the diameter of the pupil (up to 8 mm) into the human eye, so that the observer can see faint objects that were originally invisible. The focus of existing telescope photography is usually achieved by turning the r...
