Description

Technical Field

[0001] The invention relates to the technical field of telescopes, and in particular to a prism assembly for a telescope and a processing method thereof. Background Art

[0002] A telescope is an optical system composed of multiple prisms, which is mainly used to correct the refraction and reflection of light and to transform an inverted image into an upright image, thereby obtaining a clearer and more accurate image.

[0003] For example, the Chinese patent with announcement number CN201796184U (a telescope lens group with an additional focal length adjustment lens): includes a telescope objective lens group, a focusing lens, a prism group, a graticule and an eyepiece group. A group of focusing lenses that can move parallel to the optical axis of the objective lens group is added after the objective lens group, and the way of adjusting the telescope's focal length by moving the eyepiece group back and forth is changed, so that the positions of the graticule and the eyepiece group remain fixed, and the objective lens group, the prism group and the eyepiece group form a complete lens group. The focusing lens moves back and forth to adjust the focal length of the telescope. The advantage is that the way of adjusting the focal length of the traditional telescope by moving the eyepiece group back and forth is changed, and a focusing lens is set between the objective lens group and the prism group to achieve focal length adjustment. The position of the eyepiece group is fixed, ensuring that the graticule placed at the front end of the eyepiece group is always clearly imaged in the field of view of the telescope.

[0004] Most of the existing prism groups are fixed inside the telescope. When damaged, the entire telescope needs to be disassembled for replacement, which makes replacement inconvenient. In addition, when the lenses of the prism group are dried after cleaning, the drying rack is moved by pulling, which can easily cause the lenses to fall due to inertia. The protection and safety are low. Therefore, the present invention provides a prism group for a telescope and a processing method thereof. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The present invention forms a prism group by a first prism and a second prism, and the inclined surfaces of the first prism and the second prism are adjacent to each other. The prism group is wrapped by a telescope shell, and replacement openings are set on both sides of the telescope shell. The protective baffle is used for sealing and shading protection, and the first fixing component and the second fixing component are sleeved along the outer side of the protective baffle, and fixed to the telescope shell by fixing screws. The protective baffle is fixed, and the prism group, the objective lens group and the eyepiece group are fixed to prevent shaking and displacement. When the prism group, the objective lens group and the eyepiece group need to be replaced after being damaged, it is only necessary to remove the first fixing component and the second fixing component, and then pull out the protective baffle, and the prism group, the objective lens group and the eyepiece group can be replaced. There is no need to disassemble the entire telescope shell, which saves time and effort. It is not easy to damage the telescope shell during disassembly, which improves safety and convenience, and solves the problem that most of the existing prism groups are fixed inside the telescope, and the entire telescope needs to be disassembled for replacement after being damaged, resulting in inconvenience in replacement.

[0023] () A protection unit is arranged at the front end of the drying rack, the protection unit includes a protection frame and a mounting plate, the mounting plate is fixed to the upper surface of one end of the protection frame, and an extension plate is arranged on the other end surface of the protection frame, and the extension plate and the protection frame move along the external expansion slot and the movable slot respectively. When placing lenses for drying, the protection frame is moved toward the external expansion slot, and the extension plate is inserted into the external expansion slot. At this time, when the protection frame is moved down along the movable slot, the mounting plate does not contact the frame of the drying rack, so that after the protection frame moves down to the bottom, it contacts the bottom surface of the external expansion slot through the extension plate, thereby preventing the lenses from falling off. The protective guard frame is pulled upwards and then moved in the direction of the mounting plate, and the mounting plate is placed on the frame of the drying rack to limit the protective guard frame to prevent it from falling. In this way, the front end of the drying rack is protected to avoid the lenses from falling due to inertia when the drying rack is pushed and pulled, thereby improving safety. This solves the problem that when the lenses of the existing prism group are dried after cleaning, the drying rack is driven to move by pulling and pulling, which is easy to cause the lenses to fall due to inertia, resulting in low protection and safety.
