Description

Technical Field

[0001] The utility model belongs to the technical field of telescopes, and particularly relates to an astronomical telescope. Background Art

[0002] Traditional astronomical telescopes include a telescope tube, a corner mirror attachment, and a star finder attachment. The corner mirror attachment is connected to the telescope tube. The objective lens inside the telescope tube, the corner mirror inside the corner mirror attachment, and the eyepiece form an observation optical path. The user observes distant celestial bodies through the eyepiece of the corner mirror attachment. The star finder attachment is relatively independent of the telescope tube. When the star finder attachment is in use, its optical axis needs to be parallel to the optical axis of the telescope tube. Therefore, the user needs to adjust the optical axis of the star finder attachment, and the adjustment process takes a lot of time.

[0003] Moreover, when the user assembles the astronomical telescope with a camera for photography, the corner mirror attachment needs to be removed from the telescope tube first, and then the camera is installed on the telescope tube. When the user needs to observe distant celestial bodies again, the camera needs to be removed and the corner mirror attachment needs to be reinstalled, resulting in the user having to frequently disassemble and reinstall the corner mirror attachment and the camera attachment, which is very troublesome.

[0004] The information disclosed in this background art section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of implication that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Utility Model

Detailed Implementation Manner

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figures 1 to 6 As shown, this embodiment provides an astronomical telescope, which integrates the objective lens 1, the eyepiece 2, the star finder 3 and the corner mirror 5. The astronomical telescope includes an objective lens 1, an eyepiece 2, a star finder 3, a reflector 4, a corner mirror 5 and a displacement assembly 6.

[0029] Specifically, the objective lens 1 is disposed on the first optical axis 10. The eyepiece 2 is disposed on the second optical axis 11, and the second optical axis 11 has an included angle with and intersects the first optical axis 10. The star finder 3 is disposed on the second optical axis 11, and the star finder 3 and the eyepiece 2 are respectively located on both sides of the first optical axis 10, that is, the first optical axis 10 passes between the star finder 3 and the eyepiece 2. The reflector 4 is disposed at the intersection of the second optical axis 11 and the third optical axis 12, and the third optical axis 12 is parallel to the first optical axis 10. The reflector 4 can reflect the light incident along the third optical axis 12 to the star finder 3. The corner mirror 5 is movably disposed at the intersection of the first optical axis 10 and the second optical axis 11. The corner mirror 5 can reflect the light passing through the objective lens 1 to the eyepiece 2 and can block the light passing through the star finder 3. The displacement assembly 6 includes a moving member 61 connected to the corner mirror 5, and the moving member 61 can drive the corner mirror 5 to move.

[0030] According to the above structural design, refer to Figure 2 and Figure 3 As shown, when the user needs to switch the astronomical telescope to the visual state, the user moves the corner mirror 5 to the intersection of the first optical axis 10 and the second optical axis 11. The corner mirror 5 reflects the light emitted by the objective lens 1 to the eyepiece 2, and the user can directly observe distant celestial bodies through the eyepiece 2 with the naked eye.

[0031] Refer to Figure 5and Figure 6 As shown, when the user needs to switch the astronomical telescope to the star-finding state, the user moves the moving member 61 to drive the deflecting mirror 5 out of the first optical axis 10 and the second optical axis 11. The light rays emitted by distant celestial bodies are incident on the eyepiece 2 through the reflecting mirror 4 and the star-finding mirror 3. The user can quickly find the target celestial body and can conduct a more detailed observation of the target celestial body.

[0032] It can be seen from the above operation process that the user can switch the working state of the astronomical telescope by moving the deflecting mirror 5, which is very convenient. Moreover, the astronomical telescope shares the same eyepiece 2 in the visual state and the star-finding state, reducing the number of eyepieces 2 and saving the manufacturing cost. In addition, since the star-finding mirror 3 and the eyepiece 2 are always on the same optical axis, when the astronomical telescope is switched to the star-finding state, there is no need to perform parallel adjustment on the star-finding mirror 3 like a traditional astronomical telescope.

[0033] The following further introduces the shifting assembly 6 in this embodiment.

[0034] Referring to Figure 2 and Figure 5 As shown, the shifting assembly 6 in this embodiment further includes a track limiting member 62. The moving member 61 is slidably mounted on the track limiting member 62. The track limiting member 62 is used to limit the moving direction of the moving member 61 so that it moves along the extending direction of the track limiting member 62.

[0035] Specifically, the track limiting member 62 can be configured as a rod-shaped structure. Alternatively, the track limiting member 62 can also be configured as a slide rail.

[0036] Preferably, the axis of the track limiting member 62 is perpendicular to the first optical axis 10 and the second optical axis 11.

[0037] Referring to Figure 2 and Figure 5 As shown, the shifting assembly 6 in this embodiment further includes a first connecting arm 63 and a second connecting arm 64. The first connecting arm 63 can rotate around its first end. The second end of the first connecting arm 63 is rotatably connected to the first end of the second connecting arm 64. The second end of the second connecting arm 64 is rotatably connected to the moving member 61.

[0038] During specific operation, when the user rotates the first connecting arm 63, the first end of the second connecting arm 64 can be driven to move away from or close to the deflecting mirror 5. The second end of the second connecting arm 64 transmits the motion state of its first end to the deflecting mirror 5, thereby driving the deflecting mirror 5 to move. Since the moving track of the deflecting mirror 5 is restricted by the track limiting member 62, the deflecting mirror 5 can only move linearly along the track limiting member 62.

[0039] Referring to Figure 1 、 Figure 2 、 Figure 4and Figure 5 As shown in Figure 5 , to facilitate the user to rotate the first connecting arm 63, the displacement assembly 6 in this embodiment further includes a knob 66 and a connecting shaft 65. The axis of the connecting shaft 65 is perpendicular to the axis of the first connecting arm 63, and one end is fixedly connected to the first end of the first connecting arm 63, and the other end is fixedly connected to the knob 66. The user can drive the first connecting arm 63 to rotate by rotating the knob 66, and then drive the corner mirror 5 to move.

[0040] Preferably, both the first connecting arm 63 and the second connecting arm 64 are perpendicular to the first optical axis 10.

[0041] The following further introduces other structures in this embodiment.

[0042] Referring to Figure 3 and Figure 6 As shown, the astronomical telescope in this embodiment further includes a camera connector 7. The camera connector 7 is arranged on the first optical axis 10 and on the side of the corner mirror 5 away from the objective lens 1. The camera connector 7 is used to connect a camera.

[0043] According to the above structural design, on the basis of integrating the objective lens 1, the eyepiece 2, the star finder 3 and the corner mirror 5 into one body, the astronomical telescope in this embodiment also integrates the camera connector 7 for connecting a camera.

[0044] Referring to Figure 5 and Figure 6 As shown, when the user needs to switch the astronomical telescope to the camera state, install the camera on the camera connector 7, and then move the corner mirror 5 out of the first optical axis 10. The light rays emitted by distant celestial bodies can enter the lens of the camera through the objective lens 1, and the user can photograph distant celestial bodies through the camera.

[0045] It can be seen from the above operation process that when the user switches the astronomical telescope to the camera state, there is no need to first remove the corner mirror 5 and then install the camera as in a traditional astronomical telescope.

[0046] Referring to Figure 3 and Figure 6 As shown, the astronomical telescope in this embodiment further includes a first housing 8 with an axis coinciding with the first optical axis 10 and a second housing 9 with an axis coinciding with the second optical axis 11. The objective lens 1 is installed in the first housing 8, and the eyepiece 2, the star finder 3, the reflector 4 and the corner mirror 5 are installed in the second housing 9. The camera connector 7 is installed on the wall of the second housing 9.

[0047] Specifically, both the first housing 8 and the second housing 9 can be set as cylindrical structures.

[0048] Further, an opening 91 is provided in the circumferential direction of the second housing 9 in this embodiment, and the axis of the opening 91 coincides with the third optical axis 12. Moreover, the opening 91 is located on the side of the second housing 9 close to the first housing 8.
